Oxidative Stress in ED Associated with Cigarette Smoking

Cigarette smoke is a complex mixture of chemical compounds containing a high concentration of ROS, NO, peroxynitrite, and free radicals of organic compounds. These constituents get into the bloodstream and can directly activate vascular ROS production. In the general vasculature, cigarette smoking (or products of cigarette smoke) increases superoxide generation by both endothelial and smooth muscle cells from NADPH oxidase and uncoupled eNOS, and upregulates proinflammatory cytokines and the RhoA ROCK contractile pathway. This results in reduced NO bioavailability, increased vasoconstriction, and endothelial dysfunction 82, 83 . Cigarette smoking, both active and passive, is a risk factor for ED 84, 85 . Increasing evidence provided by basic science studies supports the concept that smoking-related ED is associated with reduced bioavailability of NO due to increased oxidative stress. Chronic cigarette smoke exposure impairs neuroregula-tory control of penile erection and impairs NO...

The Myth of Filtered Cigarettes

There is a mistaken popular belief that filtered brands of cigarettes, which now account for more than 97 of those sold in the United States, are safer than nonfiltered cigarettes and that formerly labeled light cigarettes convey a degree of health protection. Low-tar and low-nicotine filtered cigarettes are now the most commonly purchased products. Because the addiction is to nicotine, people who smoke low-nicotine cigarettes undergo compensatory smoking, in which they inhale more frequently and more deeply to maintain their blood nicotine levels. As a result, tar intake increases, so the cigarette changes from the low-tar to the high-tar category. Smokers who take 14 puffs per cigarette inhale 58 more tar than those taking the standard 8.7 puffs per cigarette. Most manufacturers create tiny perforations in the filter to dilute the smoke with air, thus creating their light and ultralight cigarettes. Many smokers, however, block the holes with their lips or their fingers to obtain...

Electronic Cigarettes

Electronic cigarettes (e-cigarettes), first developed in China in 2003, consist of a metal tube resembling a normal cigarette, a battery, an atomizer, and a replaceable cartridge containing liquid nicotine, propylene glycol, and flavoring. Examples of flavorings are chocolate, cherry, and bubblegum, all of which can be enticing to children. When a user puffs on the e-cigarette, an indicator light at the tip glows and the heating element vaporizes the solution from the cartridge containing nicotine and other substances. A mist is produced that is similar to cigarette smoke and contains the propylene glycol, a known pulmonary irritant used in antifreeze. To date there are no published clinical trials and there is no quality control to limit the amounts of chemicals in e-cigarettes, including known carcinogens. The sale of electronic cigarettes containing nicotine is illegal in Australia. In the United States the American Cancer Society (ACS) and other professional organizations have...

Nicotine Inhaler and Nasal Spray

The nicotine inhaler resembles a cigarette and mimics the act of smoking, thus permitting perpetuation of a behavioral ritual, but the nicotine is absorbed through the buccal mucosa rather than the lungs. Its efficacy is similar to that of the patch. The nicotine nasal spray is more rapidly absorbed than the other forms of NRT and should be a first-line treatment for heavier smokers. As monotherapy, the nasal spray has a higher odds ratio for success than the other NRT used alone (Fiore et al., 2008).

JM is a 69-year-old Hispanic male who understands English, speaks English fairly well, but does not read. He came into the Geriatric Primary Care Clinic for a cholesterol screening because he has been eating bad food for over 10 years and not exercising. He smokes one pack of cigarettes and drinks two to three beers a day. He takes a baby aspirin daily ever since he suffered a mini-stroke 2 years ago. His other medical conditions include hypertension, arthritis, chronic obstructive pulmonary disease, allergies, and Parkinson's disease. He was hospitalized for pneumonia 2 months ago. He takes nine chronic medications including his inhalers.

Nonsmall Cell Lung Cancer

The first step in treatment of NSCLC involves confirmation of the clinical stage and determination of resectability of the tumor. This decision should always be made by a thoracic surgeon who routinely performs lung cancer surgery. Treatment options depend on the advancement of disease (i.e., local, locally advanced, or metastatic), PS, and eligibility for resection.

Clinical Trials In Lung Cancer

Recently, several clinical studies have demonstrated that early stage lung cancers can be detected with the use of spiral CT that would not have been detected by routine chest X-ray.7 Spiral CT is a CT scan which does not evaluate the mediastinum and thus does not use contrast or require the presence of a radiologist, employs low doses of radiation and can be completed within one patient 'breath'. Because it can be done rapidly and does not require a radiologist to be present, it is being used in some centres to screen for lung cancers in high-risk populations. However, it has not been determined whether there is a survival benefit with this technique.6 7 Given the availability of this scanning technique in the community, it is imperative that clinical trials be completed to determine if the early detection of small tumours results in improved survival that is not a result of lead time or length bias. LUNG CANCER Chemoprevention Patients with a resected stage I NSCLC are at high risk...

Nonsmall Cell Lung Cancer Staging

Metastatic spread of NSCLC is very common, with bone, adrenal, and brain being the most common sites.14 Brain metastases occur in approximately 33 of patients. Solitary metastases are noted in approximately 30 of cases. NSCLC stages are typically designated I to IV, including subsets IIA, IIB, IIIA, and IIIB. Staging is determined using standard tumor, node, and metastasis (T, N, M) criteria. The extent of staging tests performed depends on a number of factors, including the presenting symptoms, the extent of disease, and the exact tumor type. A thorough medical history and physical examination are the most important steps in the staging and subsequent work-up of a patient with suspected lung cancer. Clinical symptoms suggestive of brain metastasis include headache, seizures, or focal neurologic deficits. If a thorough medical history and physical examination demonstrate no evidence of extrapulmonary metastases, and a chest computed tomography (CT) scan sug Patients with stage IV lung...

Brain Metastasis From Nonsmall Cell Lung Cancer

Brain metastases from tumors arising outside the central nervous system are exceptionally common. There are an estimated 75,000 to 100,000 cases of brain metastasis each year in the United States. Approximately 30 to 60 of all brain metastases originate in a primary lung cancer. In light of the marked frequency with which this illness is encountered in general oncology practice, a thorough understanding of the principles of diagnosis and treatment is essential for all practitioners. Lung cancers are primarily classified as either small cell or non-small cell lung cancer (NSCLC), with NSCLC representing more than 80 of cases. These two classes each have a distinct biologic activity and response to various forms of therapy and should therefore be considered as distinct entities from a clinical perspective. Only NSCLC will be considered in this chapter.

Cigarette smoking

Smoking is a well-documented preventable risk factor of stroke. Large observational studies have shown cigarette smoking to be an independent risk factor for stroke in both men and women e.g. 4-7 . A meta-analysis of 22 studies indicates an overall risk increase for stroke (RR 1.5 95 CI 1.4-1.6) 8 . Smoking causes changes in blood pressure and weight adjusted for age, blood pressure and obesity stroke risk was RR 2.6 (95 CI 2.3-2.9). A dose-response relationship was identified ranging from RR 2.5 (1-14 cigarettes day) to RR 3.8 (> 25 cigarettes day) 8 . Stroke risk for smokers as compared to non-smokers differed between stroke types, being highest for subarachnoid hemorrhages (OR 2.9 95 CI 2.5-3.5), nearly 2-fold for ischemic stroke (OR 1.9 95 CI 1.7-2.2) and no clear relationship for intracerebral hemorrhages (OR 0.7 95 CI 0.6-1.0) 8 . Smoking is a well-established risk factor for ischemic stroke 8 . A meta-analysis focusing only on subar-achnoid hemorrhages (SAH) found a relative...

Nicotine

When we talk about nicotine, we are basically talking about smoking, because nicotine is the addictive ingredient in cigarettes that promotes repeated smoking. Experiments have shown that the rate and frequency of smoking are adjusted to keep blood levels of nicotine in a certain range where the rewarding effects are experienced. A first cigarette usually produces negative reactions like choking and stomach upset, but with continued use, these negative feelings subside, and the addicting properties of nicotine begin to take hold. Nicotine stimulates receptors for the neurotransmitter acetylcholine, specifically the nicotinic receptors. Stimulation of these receptors causes a release of dopamine in the nucleus accumbens, a neural effect common with many other addicting drugs. The behavioral effects of nicotine are subtle and less of a worry compared to other drugs. The drug alleviates anxiety and stress, reduces aggression and anger, and causes a pleasant state of relaxation and...

Nicotine Patch

The nicotine patch is a mainstay of treatment, often combined with other forms of replacement or psychotropic medication and counseling. The main advantages of the patch are consistent delivery, easy use, and concealment. The major disadvantage is insomnia, which can be avoided by not wearing the patch at night. In a study by Cornish and Gariti (2002), by the second day of patch use, nicotine levels are about half or greater than those achieved by smoking. Quit rates at 4 to 8 weeks (depending on the study) are about double the rate of success for placebo that is, up to 70 for the nicotine patch versus up to 40 for placebo. After 1 year, the abstinence rates are about 25 for the gum and patch compared with 12 for placebo. The combination of a short-acting form of NRT (gum, lozenge, nasal spray) added to the patch increases the odds of success, because it helps control cravings and gives the smoker the ability to titrate the dose. Recent evidence also indicates that smokers who begin...

Nicotine Lozenges

Nicotine lozenges deliver slightly more available nicotine than nicotine gum, are easier to use, and have fewer gastric side effects. The lozenge comes in several flavors and should be sucked like candy, slowly, until the flavor becomes intense. It is then held between the cheek and gums, like nicotine gum, and sucked again after the flavor has diminished. It should not be chewed or swallowed. The 4-mg strength lozenge should be used for those whose first cigarette is within 30 minutes of waking, with the 2-mg strength used for lighter smokers. Smokers should use seven or eight lozenges or more per day, up to 20.

Smokers Genetics

Genetic testing may be able to indicate persons most susceptible to becoming addicted to nicotine. Addictive individuals who have a particular gene and are trying to quit may be more responsive to nicotine patches than nonnicotine measures such as bupropion (Zyban). Multiple genes are involved, however, and considerable research will be needed to create practical applications for these discoveries. Much work is currently underway regarding genes and gene mutations that predispose cigarette smokers to lung cancer. Gene methylation is a chemical modification that may be a marker for the early detection of lung cancer. The gene GPC5 has an important tumor suppressor-like function that, if insufficient, can promote lung cancer development. A variant of this gene has been found in one third of nonsmokers who develop lung cancer (Yang, 2010).

Nicotine MNP product

Nicotine is an alkaloid found in the nightshade family of plants, predominantly in tobacco. It functions as an antiherbivore chemical, being a potent neurotoxin with particular specificity to insects. In low concentrations (an average cigarette yields about 1 mg of absorbed nicotine), the substance acts as a stimulant in mammals and is one of the main factors responsible for the dependence-forming properties of tobacco smoking. The pharmacologic and behavioral characteristics that determine tobacco addiction are similar to those that determine addiction to drugs such as heroin and cocaine. Current nicotine products include chewing gum, oral lozenge, nasal spray, oral inhalant, and transdermal patch. The objective of the nicotine MNP product is to provide controlled and continuous delivery of nicotine through the skin. The MNP formulation can be customized with respect to onset and duration of action. Based on in vitro data (given below), it is expected that the MNP product will have...

Clinical trials and statistics

Simply using a coin or random numbers causes problems in small studies because of the likelihood of generating unequal groups, which cause statistical difficulties. The usual remedy is block randomization. In an intended study of 40 patients, which is probably an average-sized clinical study but in statistical terms is small, block randomization ensures two groups of 20 receive each treatment. If there are known important preoperative factors that affect outcome, e.g. smoking in a study of postoperative chest infections, randomization can be stratified, so that smokers and non-smokers are allocated by separate randomization. Clinicians must beware of confusing association between variables, whether correlation or regression, with causation. For example, alcohol consumption and incidence of lung cancer are correlated, but alcohol does not cause lung cancer. The confounding variable is tobacco use. A common cause of false association is both variables changing with time.

Types of Radiation Damage

Repair the sublethal damage, and more cells survive than if all the radiation had been delivered in a single fraction. This repair of sublethal damage may be seen as the shoulder of a cell survival curve when radiation dose is plotted against the surviving cell fraction. Some tumors, such as small-cell lung cancer, are very radiosensitive, have limited repair of sublethal damage, and exhibit a minimal shoulder on a cell survival curve. Other malignancies demonstrate a greater ability to repair sublethal damage and demonstrate a cell survival curve with a broader shoulder. Potentially lethal damage may be repaired if postirradiation conditions are suboptimal for growth. Its importance to clinical radiation oncology is uncertain. It has been postulated that some tumors that are radioresistant may be better able to repair potentially lethal damage than radiosensitive tumors.

The Rationale for Fractionation

Two common fractionation strategies used to modify radiation response are hyperfractionation and acceleration. Hyperfractionation refers to the concept of dividing a radiation dose into multiple smaller fractions given two or three times each day, with the total duration similar to that for conventional fractionation. By giving a smaller dose per fraction, the late effects of radiation are reduced, permitting the delivery of a higher total dose and thus possibly improving tumor control. Accelerated fractionation occurs when the overall treatment duration is shortened while the total numeric dose is kept approximately the same. This most commonly is achieved by giving more than one fraction per day at a reduced dose per fraction (accelerated hyperfractionation). Shortening the overall course of treatment could improve tumor control, especially where accelerated repopulation is common. Several studies have examined altered fractionation schedules with varying success in lung cancer,...

Clinical Presentation And Coexisting Risk Factors

Appropriate technique in measuring BP is a vital component to the diagnosis and continued management of hypertension in the outpatient setting. Accurate measurement of a patient's BP identifies and controls for factors that may influence the variability in the measure. Failure to consider how each of these factors may influence BP measurement results in significant variation in measurements, leading to misclas-sification or inaccurate assessments of risk. Factors including body position, cuff size, device selection, auscultatory technique, and dietary intake prior to the clinic visit may contribute to such inaccuracies. Clinicians should instruct patients to avoid exercise, alcohol, caffeine, or nicotine consumption 30 minutes before BP measurement. Patients should be sitting comfortably with their back supported and arm free of con-strictive clothing with legs uncrossed and feet flat on the floor for a minimum of 5 minutes before the first reading.

Whats in This Book and Why Should I Read It

Getting hooked on drugs is a sequence of attraction, seduction, compulsion, and pain. Drugs are dangerous and widespread, and dealing with them requires knowledge and help. This book is about alcohol, nicotine, and illegal drugs how they work, what they do to the brain, and what can be done to stop using them. The book is especially about what happens inside the brain and why the brain just happens to be set up for drugs. Yes, the brain is set up for drugs the brain is a co-conspirator, albeit an unwitting one

Detection of Telomerase by In Situ Hybridization and by Polymerase Chain Reaction Based Telomerase Activity Assay

The utility of in situ hybridization for the RNA component of human telomerase (hTR) for cancer diagnosis has been recently evaluated (13,14). Whereas the detection of telomerase activity using the TRAP assay requires fresh or fresh-frozen tumor biopsies, analysis of hTR can be accomplished using archival, formalin-fixed, paraffin-embedded specimens, as well as frozen sections and cultured cells (15-17). In lung cancer, an excellent correlation between in situ hybridization for telomerase RNA and relative telomerase activity levels has been demonstrated (18). The excellent morphologic preservation of tissue with this technique makes it a useful alternative to the PCR-based TRAP assay.

Environmental and External Factors Related to Mitochondrial ROS

The carcinogenic and toxic effects of cigarette smoking on the health of an individual are well documented. Smoking has also been shown to result in an increased likelihood of male infertility, with significantly higher levels of seminal ROS generation 123 and DNA damage 124 found in these men. Previous research has shown a significant elevation in the activity of MnSOD (mitochondrial isozyme) in cigarette smokers 125 , indicating that cigarette smoking may cause increased mitochondrial ROS generation, rather than via a cytosolic or membrane oxidase system. In smokers, the overall mitochondrial ETC function is significantly decreased which also correlates with increased peroxidative damage to lymphocyte membranes 126 . An extremely large Danish study of 2,542 healthy men, without bias towards reproductive history, discovered that compared with nonsmokers, smokers exhibited significantly decreased sperm concentration, semen volume, motility, and total sperm count 127 . Although the...

Nonpharmacologic Interventions

It is imperative that patients recognize the role of selfmanagement in HF. Nonpharmacologic treatment involves dietary modifications such as sodium and fluid restriction, riskfactor reduction including smoking cessation, timely immunizations, and supervised regular physical activity. Patient education regarding monitoring symptoms, dietary and medication adherence, exercise and physical fitness, risk factor reduction, and immunizations are important for prevention of AHF exacerbations. Modification of classic risk factors, such as tobacco and alcohol consumption, is important to minimize the potential for further aggravation of heart function. Data from observational studies suggest that patients with HF who smoke have a mortality rate 40 higher than those who do not consume tobacco products.1 All HF patients who smoke should be counseled on the importance of tobacco cessation and offered a referral to a cessation program. Patients with an alcoholic cardiomyopathy should abstain from...

The Predictability of Esthetic Implant Therapy

Practical prosthodontic procedures related to anterior maxillary fixed implant restorations. The evaluation concluded that most of these studies do not include well-defined esthetic parameters. The success rate of dental implants placed and restored in the esthetic zone has a success rate that is similar to that reported for other segments of the jaws. Single anterior tooth replacement therapy revealed that predictable treatment outcomes, including esthetics, can be achieved routinely. The research stated that implant therapy in the anterior maxilla is considered an advanced or complex procedure and requires comprehensive pre-operative planning and precise surgical execution based on a restoration-driven approach. Patient selection should be approached with caution when it comes to esthetic implant therapy, because esthetic results are less consistent in smokers and systemically involved patients.

Characteristics of Stroke

Apart from age, the most important risk factor for CVD is arterial hypertension. Control of severe and moderate, and even mild, hypertension has been shown to reduce stroke occurrence and stroke fatality. Cardiac impairment ranks third, following age and hypertensive disease. At any level of blood pressure, people with cardiac disease, occult or overt, have more than twice the risk of stroke. Other risk factors are cigarette smoking, increased total serum cholesterol, blood hemoglobin concentration, obesity, and use of oral contraceptives.

Burden of Disease

Approximately 9000 people die each year of abdominal aortic aneurysm (AAA), and most of them are men older than age 65. AAAs occur in 4 to 8 of older men and 0.5 to 1.5 of older women (Fleming et al., 2005). Major risk factors include age 65 or older, smoking (> 100 cigarettes in a lifetime), and male gender. Family history also increases risk in men and possibly in women (USPSTF, 2005). As many as one of every three untreated AAAs may rupture, and most of these individuals will die (Fleming et al., 2005).

Accuracy of Screening Tests

Ultrasound is a noninvasive test that accurately identifies AAA. It is 95 sensitive and 100 specific when appropriately performed. Physical examination is not an acceptable screening substitute (USPSTF, 2005). Patients without AAA on their initial ultrasound are unlikely to develop clinically important AAAs in their lifetimes (Fleming et al., 2005). Among men in the target age group (65-74 years), the number needed to screen to prevent one AAA-related death in 5 years is 500 smokers or 1783 nonsmokers (USPSTF, 2005).

Effectiveness of Counseling Intervention

The optimal duration and frequency of tobacco counseling interventions is unknown, but good evidence indicates that even brief counseling interventions (< 3 minutes) increase tobacco abstinence rates. Increasing the intensity of the counseling increases its efficacy (Fiore et al., 2008). The 5As behavioral counseling framework provides a useful strategy for engaging patients in smoking cessation discussions (see later discussion).Providing problem-solving guidance and social support within and outside treatment is particularly important. Patients who are unwilling to try to quit should receive an intervention designed to motivate them to quit. Several pharmacotherapies are safe and effective in helping adults to quit smoking. Nicotine replacement therapy nicotine gum, transdermal patches, nicotine nasal spray, and nicotine inhalers and sustained-release bupropion and varenicline are among the medications shown to be effective in increasing abstinence rates. There is limited evidence...

How Is Illegal Drug Use Assessed

Unfortunately, cigarette smoking, alcohol, and other drugs are seen among athletes just as they are among the general population. One should always ask about drugs in the routine health history of a patient. Whether or not a urine specimen is necessary to rule out drugs is case sensitive. At the professional and college level, athletes are required to undergo routine urine testing.

Occupational Diseases

Communities acknowledged its significance and such investigators as Wilhelm Heuper, Harriet Hardy, Irving Selikoff, and Lorin Kerr began to link exposure to dusts and toxins at the workplace to a variety of cancers. The investigations by Irving Selikoff of as-bestosis, mesothelioma, and lung cancer were particularly effective in galvanizing popular and professional attention the widespread dispersal of asbestos throughout the general environment caused profound awareness of the dangers of industrial production to the nation's health.

Reward Deficiency And Neurophysiological Adaption

This model assumes that chemical imbalance is manifested as one or more behavioral disorders called the reward deficiency syndrome (Blum, Cull, Braver-man, & Comings, 2000, para. 3). This disorder, and others like it, are linked by a common biological substrate, a hard-wired system in the brain (consisting of cells and signaling molecules) that provides pleasure in the process of rewarding certain behaviors (Blum et al., 2000, para. 3). He suggests that this reward deficiency syndrome may cause a predisposition, or vulnerability, to addiction that includes alcohol, cocaine, heroin, nicotine, sugar, pathological gambling, sex, and other behavior disorders.

Otitis Media Clinical Summary

Children between the ages of 6 months and 2 years are at highest risk of developing acute otitis media (AOM). Children at increased risk of recurrent AOM contract their first episode prior to 12 months, have a sibling with a history of recurrent AOM, are in day care, or have parents who smoke.

Historical perspective

At the incidence of lung cancer among British doctors. This study established a link between smoking and the development of small cell (oat cell) carcinoma of the lung. Further work undertaken by Doll and Hill has identified that the risk of dying from lung cancer is 32 times higher in heavy smokers compared with non-smokers (Horton-Taylor, 2001). A laboratory experiment, undertaken in 1915, proved for the first time that it was possible to develop cancer as a direct result of exposure to a chemical - coal tar. It was applied directly to the skin of a rabbit, resulting in the development of skin cancer (Yarbro, 2000a). In 1896 a German physicist, Roentgen, identified the use of radiation (X-rays) as a diagnostic tool. Further work looking at the use of radiation resulted in it being used as a new treatment for cancer by the close of the nineteenth century. However, within 7 years of Roentgen discovering the use of X-rays as a diagnostic tool, a causal link between exposure to...

01 An integrated approach of health maintenance (e.g., smoking cessation), drug therapy, and supplemental therapy (e.g., oxygen and pulmonary rehabilitation) should be used in a stepwise manner. Smoking cessation slows the rate of decline in pulmonary function in patients with COPD.

Epidemiology And Etiology

Exposures and host factors play a role in the development of COPD. Cigarette smoking is the leading cause of COPD and accounts for 80 to 90 of cases in developed countries.4 Environmental tobacco smoke (i.e., secondhand smoke) may increase the risk of COPD. Occupational exposure to dusts and chemicals (vapors, irritants, and fumes) also plays a role. Environmental air pollution has been implicated as an etiologic factor, but its exact role is unclear. Not all smokers develop clinically significant COPD, which suggests that genetic susceptibility plays a role. The best documented genetic factor is a rare hereditary deficiency of a1-antitrypsin (AAT). Severe deficiency of this enzyme results in premature and accelerated development of emphysema. Asthma and airway hyper-responsiveness have been identified as risk factors, but how they influence the development of COPD is unknown. Failure to reach maximal lung function, due to recurrent infections or exposure to tobacco smoke during...

Transdermal patch systems

The drugs that have made it into the transdermal market include sco-polamine, nitroglycerine, nicotine, clonidine, fantanyl, estradiol, testosterone, lidocaine, and oxybutinin (Langer, 2004). Recent additions to this list include lidocaine-tetracaine, selegiline, methyl phenidate, and rotigotine. However, the future focus is production of transdermal systems capable of delivering peptides and proteins including insulin, growth hormone, and vaccine across the skin.

Acute Coronary Syndromes

In ACS, African American patients are more likely to be younger and to have hypertension, diabetes, heart failure, and renal insufficiency. They are also less likely to have insurance coverage or specialist care.96,97 Recently, the investigator of CRUSADE, a large NSTEMI registry, found that African American patients were likely to receive more older ACS treatments, such as aspirin, P-blockers, and ACE inhibitors, but were significantly less likely to receive newer ACS therapies such as GP IIb IIIa inhibitors, clopido-grel, and statin therapy.96 Also, African Americans were less likely to receive cardiac catheterization, revascularization, or smoking cessation counseling. The rates of in-hospital death and postadmission MI were similar between African American and Caucasian patients in CRUSADE (adjusted OR 0.92 95 CI 0.81 to 1.05).96 However, in TACTICS-TIMI 18, African American patients were had an increased risk of death, MI, or rehospitalization (adjusted OR 1.34 95 CI 1.14 to...

Vitamin E and the Heart

A number of recent studies have attempted to determine whether taking vitamin E supplements lowers the risk of atherosclerotic heart disease and heart attacks by inhibiting low-density lipoprotein (LDL, the bad type of cholesterol). In the early 1990s, three studies found no correlation between the naturally occurring level of vitamin E in the blood and heart attacks or cardiovascular deaths. In a randomized, double-blind study, a relatively low dose of vitamin E was tested for lung cancer prevention effects. No effect on cardiovascular mortality was found.

Nonpharmacologic Therapy

Smoking Cessation Smoking cessation slows the rate of decline in pulmonary function in patients with COPD.6'7 Stopping smoking can also reduce cough and sputum production and decrease airway reactivity. Therefore, it is a critical part of any treatment plan for patients with COPD. Unfortunately, achieving and maintaining cessation is a major challenge. A clinical practice guideline from the U.S. Public Health Service recommends a specific action plan depending on the current smoking status and desire to quit (Fig. 15-2).8 Brief interventions are effective and can increase cessation rates significantly. The five As and the five Rs can be used to guide brief interventions (Table 15-3). Avoidance of risk factors), especially through smoking cessation influenza vaccination Short-acting inhaled bronchodilator when needed (e.g ipratropium, albuterol, or combination inhaler) ADD All tobacco users should be assessed for their readiness to quit and appropriate strategies implemented.

When and How to Intervene

Because many patients are not motivated, and the health rewards of behavior change are often not immediate, physicians must also take steps to avoid burnout. A long-term view is often helpful. The goal is to change readiness in increments over time and to be ready to detect a change in motivation that will allow meaningful change in behavior. It can also be the case that events will take place that cause a dramatic shift, usually caused by a change in perceived risk. These events are opportunities to explore health beliefs in the hope that they have changed. In the meantime, the best strategy is to be nonjudgmental, to feel rewarded for small changes that patients make, and to accept that some people will not change despite one's best efforts. If, for example, the annual smoking quit rate in a practice increases to 10 from a baseline of 5 of smokers per year, physicians should not despair about the other 90 , but instead congratulate themselves on doubling the rate of smoking...

Patient Encounter Part 1

A 42-year-old man with a history of diabetes and hypertension presents complaining of heartburn. He reports a burning sensation in his upper chest and some regurgitation of sour-tasting material into his throat. The symptoms began about 1 month ago, occur about twice a week, and are associated with heavy meals and lying down after eating. He says that he smokes about one pack of cigarettes per day and drinks coffee and alcohol-containing beverages on most days. His weight is 116 kg (255 1b).

Other Causative Factors

Cigarette smoking is associated with a higher prevalence of ulcers and may also impair healing of ulcers that develop.6 The exact mechanism(s) for the detrimental effects of smoking on the gastric mucosa are unclear but may involve increased pepsin reduced bicarbonate and prostaglandin (PG) production. ' It is unknown whether nicotine or one of the many other ingredients found in cigarettes is responsible for these deleterious effects.

Carcinoembryonic Antigen

Lung cancer Nonsmokers Smokers Former smokers The adult reference range for CEA is 2.5 ng mL or less for nonsmokers and 5.0 ng mL or less for smokers. The degree of CEA elevation correlates with tumor bulk at diagnosis and therefore with prognosis. Values less than 5 ng mL before therapy suggest localized disease and favorable prognosis, whereas

Squamous Cell Carcinoma

The most common sites for carcinoma in the oropharynx are the base of the tongue and the tonsil, while tumors of the soft palate and posterior wall are less common (Figure 6-6). Most squamous cancers initially expand along the mucosal surface and eventually invade the deeper structures, spreading along fascial planes and neurovascular structures. The base of the tongue is an exception because tumors tend to invade its musculature early, resulting in decreased mobility or fixation of the tongue and nodal metastasis. The anterior surface of the soft palate is affected more frequently than its posterior surface and delineation of the lesion from leukoplakia and keratinization may be difficult in heavy smokers. Tumors of the pharyngeal wall are commonly associated with extensive submucosal spread and so-called skip lesions.

Evaluation For Osteoporosis

Once diagnosed with osteoporosis, a complete medical history should be obtained with particular attention to the risk factors for osteoporosis. These include age of 65 years or older, a history of vertebral fracture or any fracture during childhood, a family history of hip fracture, low body weight (BMI < 21 or weight < 127 lb), cigarette smoking, and use of corticosteroids for more than 3 months.6 The physical examination should be performed particularly at the spine region. Height should be measured and compared with the greatest known height to determine height loss, which is an indicator of the presence of vertebral compression fractures. Balance and walking gait should be observed in each individual. The assessment of functional balance is performed by using the single limb stance test and the 6-minute walking test.

Mood Self Management and Self Help

One sees, for example, a high school student who is going to take a very important SAT exam, but who has had very little sleep for the past few nights. Or one finds people arguing or making decisions about important life issues when they are extremely tired or are under stress. Exercise is often avoided at the very times when it might be most beneficial. In addition, negative long-term effects often develop from some of the most common methods people use to manage energy and tension using drugs such as caifeine, nicotine, or alcohol. Illicit drugs are also used, but less commonly. And it may be true that the most common drug of all used for managing energy and tension is food, particularly sugar (see Chapter 8).

Pharmacologic Potentiation

Just how a drug affects restitution or substitution is often speculative. A reduction of diaschisis, promotion of collateral sprouting, denervation supersensitivity to neurotransmit-ters,180 the unmasking of latent connections, and facilitation of the cellular bases for new learning have been suggested.15,181 Other possible mechanisms include replacement of a normally present transmitter, provision of a mediator of synaptic plasticity for cortical representational adaptations, stimulation of a pattern generator, and modulation of substances such as growth factors. A variety of agents appear to enhance sprouting of den-drites and dendritic spines. Inosine and AIT-082 were mentioned earlier and nicotine and amphetamine may expand dendrites in frontal regions (see Experimental Case Studies 2-6). Some drugs will have more clear-cut mechanisms of action. For example, 4-aminopyridine may partially restore the conduction of action potentials along demyelinated axons. The drug blocks...

Persons Who Have Used Contrarian Strategies

The Los Angeles Times also published an article, Renegades Reinvent the Bicycle. Apparently the mountain bike - a modification of what Britannica called the most efficient means yet devised to convert human energy into propulsion - came out of nowhere, a product of counterculture - invented by hippies, no less, a ragtag of pot-smokers and Haight-Ashbury drifters who barely got through high school. Note the term counterculture -a group of contrarians.

Lung Disease in Primary Care

Breathing and heartbeat draw the line between life and death. Pulmonary disease, respiratory symptoms, and respiratory failure are common, high-impact conditions. For example, asthma is the most common chronic disease of childhood, respiratory failure causes many admissions to our nation's intensive care units (ICUs), and lung cancer is now the leading cause of cancer death for both men and women in America. Lung cancer accounts for 31 of cancer deaths in men and 25 of cancer deaths in women (American Cancer Society, 2002). In part because of the global spread of tobacco, the World Health Organization (WHO) estimates that chronic obstructive pulmonary disease will move from

Smoking and Other Risk Factors for Lung Disease

Than 400,000 deaths per year, or one in every five deaths. People who smoke suffer more than a 20-fold increase in risk of death from lung cancer and a 10-fold increase in risk of death resulting from bronchitis or emphysema (CDC, 1993). For women in the United States, there are more deaths caused by lung cancer than by breast cancer. Worldwide there were 5 million deaths attributable to smoking in 2000, almost 2 million of which were related to lung cancer and other lung diseases. WHO projects a doubling of smok-ing-related deaths by 2020 (Ezzati, 2003). Smoking cessation is the most important factor in preventing lung and cardiovascular disease and all-cause mortality. Avoidance of secondary exposure to smoke, especially in the household, is also important in preventing childhood asthma and infections as well as adult cancers (DHHS, 2006). Even simple physician advice to quit smoking provides a marginal benefit of 2.5 of patients quitting successfully (Lancaster and Stead, 2004)....

Cardiovascular disease

Smoking causes vasoconstriction and is associated with Buerger's Disease, a condition causing intermittent claudication and gangrene. Moseley et al. (1978) suggested that smoking also interfered with the proliferation of erythrocytes, thereby reducing the available oxygen. A review of the effects of smoking on wound healing by Siana et al. (1992) found that nicotine affected macrophage activity and reduced epithelialisation and wound contraction. Jorgensen et al. (1998) found that smoking impedes collagen synthesis and recommended that patients be advised to stop smoking prior to surgery.

Epidemiology and Risk Factors

The strongest risk factors for developing asthma are exposure to household smokers and a family history of asthma or atopy (asthma, atopic dermatitis, or allergic rhinitis). Family history of nasal polyps or aspirin hypersensitivity can also suggest risk for IgE-mediated atopic disease. Data are mixed on the impact of early childhood infections and bottle feeding versus breastfeeding on the development of asthma, although both are clearly associated with wheezing episodes in the first 3 years of life. Data showing a paradoxical protective effect of early childhood exposure to pets, farm animals, and bacterial antigens are still controversial (Adler et al., 2005 Platts-Mills et al., 2005 Remes et al., 2005 Waser et al., 2005).

Clinical Presentation and Diagnosis

A complete history in patients suspected of having asthma should include the frequency and severity of recent symptoms and should distinguish between daytime and nocturnal symptom frequency, a factor that is also important in staging asthma. A history of past or present smoking (tobacco or other drugs) is essential, as is an inquiry about current passive exposure to smokers in the household or occupational secondary exposure to tobacco smoke (e.g., bartenders, restaurant staff). The clinician should also inquire about activities, acute illnesses, or environmental exposures that trigger episodes, a family history of asthma or atopic disease, and a detailed occupational history. Some patients are also exposed to bronchial irritants through hobbies such as woodworking or oil painting.

Clinical Presentation

Often, patients who smoke have had a chronic smoker's cough for years and present for medical treatment only when symptoms such as shortness of breath on exertion or at rest begin to appear. The hallmark symptom of symptomatic COPD is progressive and persistent shortness of breath. Because of the built-in reserve of the pulmonary system, such functional disability often is not noticed until there is a substantial decline in pulmonary function and substantial damage to lung parenchyma. Still, the U.S. Preventive Services Task Force (USPSTF) recommends not screening routinely with spirometry for obstructive lung disease or declining lung function.

Social Class Structure and Mental Health

In a recent study we further examined the relationships between measures of social class (Wright's social class indicators, i.e., relationship to productive assets) and indicators of mental health (Borrell et al., 2004). We tested this scheme using the Barcelona Health Interview Survey, a cross-sectional survey of 10,000 residents of the city's non-institutionalized population in 2000. Health-related variables included self-perceived health (tapping mostly mental health), nicotine addiction, eating behaviors, and injuries. Findings revealed that, contrary to conventional wisdom, health indicators are often worse for employers than for managers, and that supervisors often fare more poorly than workers. Our findings highlight the potential health consequences of social class positions defined by relations of control over productive assets. They also confirm that social class taps into parts of the social variation in health that are not captured by conventional measures of social...

The Health and Occupational Reporting

The Health and Occupational Reporting (THOR) is an example of a UK system for occupational disease surveillance. THOR activity at the Centre of Occupational and Environmental Health, University of Manchester has a range of surveillance programmes. It includes surveillance of work-related and occupational respiratory disease (SWORD), particularly occupational asthma, benign and malignant pleural disease, mesothelioma, lung cancer, and pneumoconiosis surveillance. The most common cause of occupational asthma in the UK consists of the di-isocyanates (used in various industries such as in 'twin-pack' spray painting). Other important asthma hazards include colophony fume (from soldering flux). The SWORD scheme successfully picked up trends such as an increase in asthma associated with exposure to latex, and thus helped in raising awareness and reducing the risks.

General Considerations

Oral cancer represents about 3 of all cancers. Cancer of the oral cavity and pharynx was responsible for 7550 deaths in 2007, killing approximately 1 person per hour, 24 hours per day. The rate of death from oral cancer is higher than those from cervical cancer Hodgkin's disease cancer of the brain, liver, testis, kidney, or ovary or malignant melanoma. One of the reasons for this high death rate is that the cancer is routinely discovered late in its development, with metastases to other areas or invasion deep into local structures. Oral cancer is also particularly dangerous because it has a high risk of producing second primary tumors. This means that patients who survive a first encounter with the disease have up to a 20 times higher risk for development of a second cancer. There is a 2 1 male-to-female incidence ratio and a 2 1 African-American-to-white death rate ratio. It is estimated that a man has a 1 72 lifetime risk for development of oral cancer. The American Cancer Society...

Patient Encounter 1 Part 1

HPI BA is a 58-year-old male recently diagnosed with lung cancer. Following surgery he was placed on morphine patient-controlled analgesia (PCA). He has been using 80 mg of morphine 24 hours with adequate pain control. SH Lives with wife has four grown children smoked two packs of cigarettes per day x 40 years (quit with diagnosis of lung cancer)

Epidemiology and Presentation

Outside the United States, the most common cause of pleural disease is tuberculosis. In the United States, TB is still significant, but other disorders, such as pneumonia, HIV-related infections, connective tissue disease (especially lupus), and malignancies (mesothelioma, peripheral lung cancer) must also be considered. Pleural effusions can be caused by systemic sources of transudate (CHF, hepatic failure with ascites, autoimmune disease) or by local inflammatory processes (parapneumonic effusion, pancreatitis, neoplasia).

Intracranial Carotid Artery Dissection

A 46-year-old woman arose and prepared for work. She was found on the floor a few hours later by her husband. She was awake but could not speak or move her right side. Her husband reported that she had complained of a severe headache in and over her left eye the day and night before. There was no history of transient ischemic attacks, migraine headaches, or neck or head trauma. She did not have hypertension, diabetes, or heart disease, and was not taking oral contraceptives. She did smoke cigarettes.

Epidemiological studies

These studies, conducted with unexampled care and the closest adjustment for the effects of confounding factors, have shown that long-term exposure to fine particles is associated with an increase in the risk of death from cardiovascular disease and from lung cancer. It is worth noting that the studies show that long-term exposure to 10 g m3 of fine particles (PM25) is associated with a 6 increase in the risk of death from all causes and a 9 increase in the risk of death from cardio-pulmonary causes. This is a large effect and implies a heavy burden on public health. Adjustment for confounding factors is critically important and, in these studies, factors such as social class, smoking habits, diet, alcohol intake, and education have been found to be important.

Assessing applicability

After evaluating validity and analysing the results of a trial, the next step is to decide if the results can be applied to our own patients. Trials provide information that can help us decide this. For example, we can check if our patients' characteristics satisfy the inclusion and exclusion criteria. We can also look at treatment effects in subgroups of patients that more closely approximate the individual patient we are trying to help (subgroup analysis). Unfortunately, in real life there are simply too many patient subtypes and trials are typically too small to address more than a few subgroup hypotheses. It would be very unlikely for example, that we find a trial on a drug for hypertension which analyses effects among male smokers aged 40-45, weighing 60-70 kg, with a total cholesterol of 6-7 mmol Li and a family history of stroke

What It Can Do for You

Hypnosis is not a cure-all for physical, emotional, or addictive disorders. It cannot reprogram the body and mind to stop smoking or drinking, for example. It cannot cure serious disease and should never be used as an alternative to conventional, mainstream medicine. It is not recommended for the treatment of psychosis, organic psychiatric conditions, or antisocial behavior.

Patients present with either ischemia or subarachnoid bleeding Patients presenting with ischemia rarely develop

A 19-year-old college student reported to the infirmary at the university when he discovered that he could not see to his right. During the previous days he had had some discomfort in his right shoulder and in the back of his neck and head. He was an athlete and played on the volley ball and soccer teams of his university but recalled no unusual trauma. He had no past medical ills and did not smoke cigarettes or take drugs of any kind.

Stress Exercise and Drug Manipulations

Some recent research in my laboratory suggests that sugar ingestion (Thayer, 1987a) and cigarette smoking may also be used to induce either energetic or tense arousal. And finally, arousal-affecting manipulations of sleep states have been extensively studied in relation to moods. A later chapter will concentrate more fully on these kinds of studies.

Indoor air pollutants

The indoor environment presents special problems direct sources of pollutants such as cookers and fires may vent into the limited indoor space. This can lead to high indoor concentrations of pollutants, especially in houses with a low air exchange rate. Modern trends in building design, which reduce the need for space heating by insulation, exacerbate this problem. Some pollutants, including organic species released by carpets and adhesives, reach effective concentrations only indoors formaldehyde, released from composition boards, is also a special indoor air problem. The dangers of indoor exposure to carbon monoxide have been discussed above. Tobacco smoke is also a special indoor air problem high concentrations of carbon monoxide and nitrogen dioxide are found in tobacco smoke.

Implications for Clinical Therapeutics

Trastuzumab (Herceptin), a humanized monoclonal antibody directed against Erb-B2 (Her-2), has undergone several phase II and phase III clinical trials that have demonstrated a survival benefit in patients with Her-2-overexpressing breast cancers.89 These studies have led to the licensing of trastuzumab in many countries for use in combination with paclitaxel. EGFR antagonists are also being aggressively investigated. Cetuximab (IMC-225, Erbitux), a monoclonal antibody that binds the extracellular domain of EGFR, has been investigated in phase II and phase III trials in colorectal cancer, non-small cell lung cancer (NSCLC), and squamous cell carcinomas of the head and neck. Early results show good response rates and few toxicities.

Other Methodological Issues

Failure to take these insights into account leads to a ''low birth weight paradox,'' viz., puzzlement over the finding that ''LBW babies in high-risk populations . . . usually have lower mortality than LBW babies in better-off populations'' (Wilcox 2001a 1234). A prime example occurs in what at first glance seems to be an enigmatic effect of smoking. While it early became clear that both low birth weight and infant mortality are more likely among babies of mothers who smoke, it was also discovered that ''LBW babies born to mothers who smoked had lower infant mortality than the LBW babies of mothers who did not smoke'' (Wilcox 2001a 1234 emphasis in the original). The puzzle is solved when infant mortality is plotted by relative birth weight (adjusted to z-scores), in which case '' m ortality with mother's smoking is higher across the whole range of weights'' (Wilcox 2001a 1237).

Behavioral Definitions

Demonstrates a maladaptive pattern of tobacco use, manifested by increased tolerance and withdrawal. 3. Exhibits physical indicators (chronic obstructive lung disease, bronchitis, lung cancer, oral cancers, etc.) that reflect the results of a pattern of heavy tobacco use. 4. Denies that nicotine dependence is a problem, despite feedback from significant others that the use of tobacco is negatively affecting them and others. 5. Continues tobacco use despite knowledge of experiencing persistent physical, financial, vocational, social, and or relationship problems that are directly caused by the use of nicotine. 6. Presents with physical withdrawal symptoms (e.g., nicotine craving, anxiety, insomnia, irritability, depression) when going without nicotine for any length of time. 9. Nicotine dependence is concurrent with other addictive behaviors, and their practice reinforces one another.

Does the Brain Ever Get Back to Normal

Here is an anecdote from my own history. As a young man, I smoked tobacco for years. But, when a relative died of lung cancer, I decided to stop smoking and much to my surprise (it shouldn't have been) I craved tobacco for a long time The second six months of abstinence produced worse craving than the first six months (at least it seemed that way). I especially craved when others smoked after a meal, which was the time when I enjoyed smoking the most. Sometimes I would even get up and leave the table so I wouldn't be affected by others' lighting up. After about a year, the craving for tobacco began to reduce, and after about 18 months, I experienced no craving at all. Today, many years later, smoking bothers my throat and lungs and leaves me coughing, and I consider myself totally cured of that addiction. Because of this, I feel that addiction is curable (at least in my case). Still, I can't be absolutely sure that there isn't some residue of change left in my brain that somehow...

Therapeutic Interventions

Complete psychological testing or objective questionnaires for assessing nicotine abuse dependence. (3) 3. Administer to the client psychological instruments designed to objectively assess nicotine abuse dependence (e.g., Addiction Severity Index ASI , Substance Abuse Subtle Screening Inventory-3 SASSI-3 , Fagerstrom Test for 6. Attend group therapy sessions to share thoughts and feelings associated with reasons for, consequences of, feelings about, and alternatives to nicotine abuse. (9, 10) 7. List the negative consequences resulting from or exacerbated by nicotine dependence. (11) Nicotine Dependence FTND ) give the client feedback regarding the results of the assessment. 5. Complete a thorough family and personal biopsychosocial history that has a focus on nicotine abuse and any other addictions. 6. Assign the client to attend a nicotine dependence didactic series to increase knowledge of the patterns and effects of nicotine dependence. 7. Require the client to attend all nicotine...

High risk of bias due to incomplete outcome data

Even if incomplete outcome data are balanced in numbers across groups, bias can be introduced if the reasons for missing outcomes differ. For example, in a trial of an experimental intervention aimed at smoking cessation it is feasible that a proportion of the control intervention participants could leave the study due to a lack of enthusiasm at receiving nothing novel (and continue to smoke), and that a similar proportion of the experimental intervention group could leave the study due to successful cessation of smoking. The common approach to dealing with missing outcome data in smoking cessation studies (to assume that everyone who leaves the study continues to smoke) may therefore not always be free from bias. The example highlights the importance of considering reasons for incomplete outcome data when assessing risk of bias. In practice, knowledge of why most participants drop out is often unavailable, although an empirical study has

Conclusions And Research Directions

Although the U.S. population is generally healthy with good longevity prospects, several factors may hamper future gains. For instance, the increasing prevalence of obesity is an alarming trend and presages increasing mortality from diabetes, heart disease, and some forms of cancer. Further, in the four decades since the U.S. Surgeon General brought to public attention the hazards of cigarette smoking, nearly a quarter of the U.S. adult population continues to smoke, and surprisingly large proportions of individuals start smoking every year. These patterns threaten to offset improving longevity prospects that result from increasing levels of education and public health efforts and are especially pernicious as they disproportionately affect racial and ethnic minorities (U.S. Department of Health and Human Services 2000). There is an opportunity to better understand the social and contextual influences on mortality. Although much work has focused on various social relationships,...

Nicotinic Hypofunction

Patients with schizophrenia are notoriously heavy smokers, which lead researchers to examine the cholinergic system of the brain. Smoking may be a form of self-medication since gating deficits are temporarily restored by stimulation of the nicotine receptor, specifically the a7-nicotinic receptor (Adler et al., 1998). There is an abnormal expression of a7 -nicotinic receptors in the hippocampus of postmortem brain from schizophrenia patients. While this was originally believed to be simply a consequence of heavy smoking, it is now being revisited as an inherited vulnerability factor since linkage studies have found a dinucleotide polymorphism at chromosome 15q13-14, the site of the a7-nicotinic receptor (Freedman et al., 1997).

Mothers Health Babys Risks

Risks for a child can be caused by maternal age (a mother who is older or an adolescent), obesity or malnutrition, high blood pressure, or any number of infectious diseases. Low birth weight, which puts a newborn at a higher risk for complications due to underdeveloped organs and body systems, has been linked to the mother's use of nicotine, alcohol, and both illegal and certain prescription drugs during pregnancy.

Adrenalectomy For Solitary Metastasis

Patients with metastatic lung cancer typically have a poor prognosis. Only 7 of patients present with solitary metastasis (10). Although still controversial, a survival advantage has been noted in patients with solitary adrenal metastasis from a non-small cell lung malignancy, whether synchronous or metachronous (11-15). These published series, with relatively small numbers and intermediate follow-up, have reported survival in this very select subset of patients. Luketich and Burt (11) compared the median survival of eight patients with isolated adrenal metastases from lung cancer who underwent adrenalectomy and chemotherapy with six patients who underwent chemotherapy alone. The median survival in the surgical group was found to be significantly increased (31 months) versus the chemotherapy alone group (8.5 months, p 0.03). In another study, survival was noted in a multicenter trial of 43 patients with isolated adrenal metastases (32 synchronous, 11 metachronous) for patients with...

Laparoscopy For Malignant Adrenal Lesions

Our review of 31 patients (33 procedures) with malignant adrenal lesions is the largest published experience to date (33). The cohort comprised metastatic cancer (n 26) and primary adrenal malignancy (n 7). Mean adrenal tumor size was 5 cm (range, 1-10 cm). Mean operative time was three hours with estimated blood loss 258 cc and a mean hospital stay of 2.1 days. Of the 33 procedures, one was electively converted to open surgery. There was no operative mortality. The metastatic group consisted most commonly of RCC (n 13), colonic malignancy (n 6), and lung cancer (n 5). With a median follow-up of 26 months, 17 (55 ) were alive, of whom 15 (48 ) had no evidence of disease. Five-year actuarial survival was 40 . Seven (23 ) patients had local recurrence with no cases of port-site metastasis. Local recurrence was associated with an inferior survival when compared to no local recurrence (p 0.016). Survival did not correlate to a patient's age, gender, tumor size, tumor side, or surgical...

State Dependent and Congruent Memory Processes

First, state-dependent learning has frequently been demonstrated with animals as well as with humans (Overton, 1984). In such research, drugs that act on the central nervous system are employed to demonstrate that if learning occurs or attention given during a particular drug state, when the subjects are reintroduced to that same drug state later, they will have a better memory of what was learned than if recall is attempted in a nondrugged or a different drug state. This state-dependent memory retrieval has been demonstrated with such well-known drugs as alcohol and marijuana, as well as with a wide range of others, including various anesthetics, narcotics, anxiolytics, and stimulants. Even nicotine was recently employed to show state dependency (Peters & McGee, 1982). Early theorizing about this phenomenon centered on particular brain mechanisms, but more recent ideas have focused on the conditioning of stimulus contextual cues (cf. Tulving & Thompson, 1973) arising from the...

Epidemiologic Overview

NSCLC is the most common form of lung cancer. It is the leading cause of cancer-related deaths in the United States for both men and women and is estimated to cause 160,000 deaths per year.10 Although the incidence of new cases of lung cancer for men appears to be at a plateau of 80 cases per 100,000 people, the incidence among women is rising, presumably because of increased smoking by women. Eight-seven percent of lung cancer cases are related to smoking, with a strong correlation between the amount of tobacco exposure and the risk of developing lung cancer. Approximately 33 of patients with NSCLC develop metastases to the brain during the course of their disease.

Role Of Brain Imaging Before Lung Resection

Most patients with stage IV cancer are not considered surgical candidates with regard to their lung tumors. There is little debate as to the benefit of brain imaging in patients exhibiting neurologic signs or symptoms suggesting a brain metastasis. The role of such imaging in asymptomatic patients is more difficult to define. One important consideration is that the discovery of an asymptomatic brain metastasis will often direct lung cancer therapy away from curative and toward palliative modalities. This raises the question of whether all patients with lung cancer should undergo brain imaging before surgery on the lung primary. A review of recent literature yields somewhat ambiguous results.

Synchronous Brain Metastasis And Isolated Thoracic Disease

The role of surgery can also be critical in the case of an asymptomatic brain mass identified as part of the initial staging work-up for a patient with newly documented lung cancer. Because asymptomatic intracranial meningioma and other benign neoplasms may be discovered on any screening CT or MRI scan, it would be imprudent to assume that a solitary lesion identified in a patient with lung cancer is necessarily metastatic. In this situation there may be a role for surgery to define the pathologic nature of the intracranial lesion, in addition to any therapeutic benefit derived from surgical resection. We have seen several cases in which a presumptive brain metastasis has been excised, only to discover that this lesion was a meningioma. Conversely, we have operated on several patients with presumptive meningioma that has turned out to be metastatic carcinoma. Failure to adhere to this principle may exclude some stage I or II NSCLC patients from curative surgery or, conversely, expose...

Wholebrain Radiation Therapy

NSCLC patients with brain metastases have a median survival time of 3 to 7 months, depending on ambulatory status, primary tumor control, and presence of extracranial metas-tases.9 Increased age, decreased KPS score, and more extensive extracranial disease all predict a worse response to therapy. In predicting the prognosis, KPS score should be based on the patient's status after a response to steroids.9 WBRT yielded a median survival of 28 weeks for lung cancer patients who were ambulatory, had a primary tumor that was controlled, and had no evidence of extracranial metastases.

Illustrative Case

A 56-year-old woman who was an ex-smoker was found to have a left lower lobe pulmonary mass 2 cm in maximal diameter. On careful questioning, the patient reported mild disequilibrium. An MRI scan of the brain revealed a solitary lesion 2.5 cm in maximal diameter in the left cerebellum. The remainder of the metastatic work-up revealed no evidence of disease. She underwent craniotomy for removal of the brain metastasis, followed by thoracotomy for resection of the lung primary. The FIGURE 53-2 Metastatic non-small cell lung cancer FIGURE 53-2 Metastatic non-small cell lung cancer

Formation of Reactive Metabolites

Nicotine appears to be both a psychostimulant drug and a common environmental pollutant promoting ''passive smoking.'' It should be also considered to be a drug of addiction, since thousands of heavy tobacco smokers are unable to give up smoking, showing therefore a true dependence on nicotine. Smoking and inhalation are routes of administration that allow a very rapid delivery of the drug to the brain, and the first daily puff on a cigarette is considered by tobacco smokers to be ''the best one'' because it efficiently attenuates the morning's withdrawal symptoms. Nicotine is a pharmacologically active tertiary amine, efficiently metabolized to cotinine by both liver and brain CYP (76) through the formation of a reactive nicotine-A 1'(5') -imminium ion, which is an alkylating species (77). During its metabolism, nicotine undergoes covalent binding to microsomal protein, supporting the concept that reactive metabolic intermediates may play a role in the pharmacology and toxicity of...

Ionexchange materials

Conaghey et al. (1998) studied the in vitro iontophoretic transdermal delivery of nicotine by ion-exchange resins in agar hydrogel. Both strong and weak resins were used and the heterogeneous vehicles were shown to have advantages over comparable simple hydrogel vehicles in their versatility, in their capacities to store the drug, and to control the delivery rate during iontophoresis. Kankkunen et al. (2000, 2002, 2004) studied controlled transdermal delivery of the zwitterionic levodopa by iontophoresis and ion-exchange fiber. Ion-exchange kinetics and transdermal permeation of a cationic (presumably more stable) model drug, metaraminol, were compared to the corresponding data for levodopa. Levodopa was rapidly oxidized in the presence of water, especially at basic pH. At acidic pH, stability was improved significantly. Ion-exchange groups and pH had a clear effect on the release of both the levodopa and metaraminol from the ionexchange fiber. Iontophoretic enhancement of drug...

Central Nervous System Metastases

Breast cancer can spread to the CNS in one of three ways. Solid brain tumors are the most common end point (85 to 95 ), carcinomatous meningitis is next in frequency (approximately 5 to 15 ), followed most rarely by intraparenchymal spread to the substance of the spinal cord (approximately 1 ). Breast cancer is the second most common cause of solid brain metastases after lung cancer, accounting for 14 to 20 of the total (an even larger percentage among women). Estimates of the prevalence of symptomatic CNS metastases among patients with breast cancer range from 5.9 to 16.2 . By the time of autopsy, prevalence rates have increased to 18 to 30 of patients. CNS invasion is more likely to occur in premen-opausal women with widely disseminated disease and in patients with estrogen-receptor-negative tumors. Recent reports have speculated that brain metastases may occur more commonly in patients treated with trastuzumab (Herceptin).25,131 In approximately 20 of patients who develop CNS...

Clinical investigation

Most patients with oral cancer are likely to be heavy smokers and drinkers. It is important that all investigations necessary for deciding whether the patient is physically and mentally fit for treatment are carried out. Particular attention should be paid to the cardiovascular and respiratory systems, the nutritional status of the patient, and his or her social circumstances. A psychological assessment can also be of value. This is to allow an informed decision to be made on any further treatment.

General Characteristics

The IBD are more frequent among whites than blacks, but Crohn's disease is increasing among black populations of the United States and Britain. Ulcerative colitis and especially Crohn's disease are much more common among Jews of the United States, Britain, and Sweden than among other groups. Ulcerative colitis and Crohn's disease occur among all ethnic groups, including Maoris, Arabs, and probably the Chinese, albeit infrequently. There is a scarcity of cigarette smokers among ulcerative colitis patients, and ex-smokers apparently have an increased vulnerability to it. By contrast, there is an excess of smokers in Crohn's disease populations. This intriguing observation, however, has yet to be explained.

Prognosis Studies of disease course and outcomes

'We both know that smoking cigarettes caused your lung cancer.' Smoking tobacco causes lung cancer. (Premise A) 'You must stop Smoking must stop if Do the results of clinical trials and other smoking the patient's survival analytical studies show that stopping Astute readers will note right away that two of several valid premises are available. Each premise is supported by extensive etiological research (premise A) and survival studies (premise B). Is conclusion C a natural corollary of premises A and B, which are supposed to support and lead to that conclusion Conclusions in this example do not follow from other, equally solid evidence that tobacco smoking is not only a predominant etiological (risk) factor of bronchial cancer, but also a prognostic one. Are there studies, particularly clinical trials, which show that if lung cancer patients stop smoking, their life expectancies will increase Or does quitting smoking merely offer a chance to improve some symptoms Neither focus, nor...

Additional Resources

Defining addiction as a disease relieves addicts of the overwhelming shame and responsibility for having caused the addiction and its devastating consequences. At the same time, it empowers the client to take corrective action. Refuting the discouraging idea that addiction is a moral failure allows clients to focus on getting better by accepting the hard truth Abstinence is their solution. Just as lung cancer patients are expected to stop smoking and diabetics to avoid sugar, addicts must altogether avoid ingesting alcohol and other psychoactive drugs as part of their recovery.

Trials Of Behaviour Change

And pressure can affect the trials in major ways. If there are changes in restaurant or workplace smoking regulations during the time of a trial looking at ways to get people to stop smoking, the likely trends in the control group as a result of the new regulations will make detection of benefit from the intervention more difficult. the need to stop smoking, improve diet and get better preventive medical attention.

Degradation of Complement Proteins with Proteases

Demonstrated that such proteases can also cleave complement components and, thus, inhibit complement activation (Ollert et al., 1990 Jean et al., 1995, 1996). Best studied is the degradation of C3, a key protein in the complement cascade, by tumor proteases. Human melanoma cells contain a C3-cleaving serine protease, p65, that rapidly degrades surface deposited C3b and is mostly expressed on the surface of melanoma cell lines resistant to complement-mediated lysis (Ollert et al., 1990). Blocking studies revealed that p65 contributed to resistance of melanoma cells to human complement. A C3-cleaving cysteine protease related to procathepsin-L, p39, was also identified on the membrane and in conditioned medium of murine melanoma cells (Jean et al., 1995). Inhibition of p39 with specific antibodies caused increased susceptibility of murine melanoma cells to complement lysis. A human cystein protease, antigenically related to murine p39 and to human procathepsin-L, was purified from a...

Patients Outcome And Adjuvant Treatment Of Systemic Disease

In a 2001 study of patients with brain metastases from an unknown primary tumor, survival was comparable in those whose primary tumor became known during follow-up and in those in whom it remained occult.41 Overall survival was not affected by disclosure of the primary site, because most patients with brain metastases were ultimately found to have lung cancer, for which effective systemic therapy is unavailable. However, a few patients received specific treatment in a timely fashion, which probably resulted in their improved survival.

Sensitivity analyses based on selection models

Copas developed a model in which the probability that a study is included in a meta-analysis depends on its standard error. Because it is not possible to estimate all model parameters precisely, he advocates sensitivity analyses in which the value of the estimated intervention effect is computed under a range of assumptions about the severity of the selection bias (Copas 1999). Rather than a single intervention effect estimated 'corrected' for publication bias, the reader can see how the estimated effect (and confidence interval) varies as the assumed amount of selection bias increases. Application of the method to epidemiological studies of environmental tobacco smoke and lung cancer suggests that publication bias may explain some of the association observed in meta-analyses of these studies (Copas 2000).

Question 2 How precise is the estimate of the risk

In contrast, the 2x2 table in Panel B shows that the sampling in case-controls is vertical we recruit cases (persons with the outcome) and controls (persons without the outcome) and determine the proportion who were exposed. The rational comparison in this case would be risk of exposure among cases and the risk of exposure among controls, i.e. a (a + c) + b (b + d). This may be referred to as the relative risk of an exposure. This would be a useless number. It would be like telling a patient 'Sir, you have lung cancer, there is a 10-fold rise in the risk that you are a smoker' 3. To counter this problem, statisticians use the odds of exposure a c ('a is to c') and b d ('b is to d') instead of the risk of the exposure which is a (a + c) and b (b + d). (You might want to review Tackle Box 3.2, if you find this confusing.) The ratio ofodds would then be (a c) + (b d). This is still a vertical comparison. Instead of the useless relative risk of exposure, we have converted it to a useless...

Fight Back with Antioxidants

Unfortunately, harmful agents called free radicals are produced when we breathe and process oxygen. In fact, these destructive bad guys can also be produced as a result of pollution, stress, pesticides, asbestos, x-rays, preservatives, exhaust fumes, tobacco smoke, and injury. As discussed in a previous chapter, free radicals trek all over the body and actually destroy the cell's DNA a cancer-promoting activity. The good news is that we naturally protect ourselves by forming antioxidants, substances that help our body's defense system fight off free radicals and preserve healthy cells.

Other Mood Related Topic Areas

The effects of drugs on mood is another topic that has generated a large amount of published research. In the past ten years, the greatest number of studies has concerned the effects of alcohol on mood, but a number of studies were also published concerning the effects of benzodiazepines (e.g., Valium), amphetamines, caffeine, and nicotine on mood. The multivolume edited work, Handbook of Psychopharmacology, is an excellent reference for much of this research (Iversen, Iversen, & Snyder, multiyear).
