Influence on Scar Remodeling

It is apparent that the scar formation and wound contracture that are an integral part of the orderly healing of hand tissues may have a great influence on tendon gliding and joint movement. Measures designed to prevent digital stiffness include elevation, positioning of joints to lessen the possibility of collateral ligament shortening, implementation of early motion programs, relief of pain, control of edema, elimination of hematoma formation, prevention of infection, and the use of splints. Although very little meaningful scientific information has been provided to indicate at which points during the healing process it is most appropriate to use immobilization, mobilization, restriction, and or torque transmission splints to favorably control the production and remodeling of scar tissue, a review of the biologic sequence of the reparative process may allow us to draw some reasonably sound conclusions. After the sixth week of wound healing, during the period of scar maturation and...

Management of scars

Scars in the head and neck are not only disfiguring and noticeable but often have a social stigma attached. Initial wounds can look quite satisfactory but, as healing progresses, scar formation develops. This appears as reddening and increasing size of the scar as it tends to become wider and raised from the skin surface. The scar becomes hard and can be associated with itch and pain. As the scar matures it should become softer paler and flatter. The final scar should look paler than the surrounding skin, flat and soft and have an atrophic appearance (i.e. look thinner than the surrounding skin), with no skin appendages such as hair or sweat glands. This cycle of scar maturation can take 1-2 years, and patients often require support throughout this phase. Occasionally, intralesional injection of corticosteroids can accelerate the process of maturation it can also be a useful treatment for itchy and painful scars. Cosmetically unsightly scars are usually those that cross the lines of...

Hypertrophic Scars

Hypertrophic scars are limited to the wound edges and tend to regress over the first year. The treatment of both keloid and hypertrophic scars is similar, except hypertrophic scars have better outcomes. Genetic expression of various cytokines and inflammatory pathways may affect the myofibrocytes in granulation tissue to continue producing scar the exact causes are being investigated. Pressure dressings and colloidal silicone placed on scars after suture removal or on burn scars may reduce the incidence of both keloids and hypertrophic scars, whereas onion-skin extract (Mederma) alone is not effective (Karagoz et al., 2009). Hypertrophic scar fibroblasts exhibit resistance to a specific form of apoptosis, or cell death, elicited by contraction of collagen matrix gels. This phenomenon depends on excess activity of cell surface tissue transglutaminases (Linge et al., 2005). Pressure dressings in burns help prevent hypertrophic scars (SOR B). Intralesional corticosteroid injections are...

Limit Glial Scar

Immediately after a spinal cord contusion, pe-techial hemorrhages and tissue damage spread and enlarge in centripetal and rostrocaudal directions for up to several days. Resident and activated inflammatory cells infiltrate an increasingly necrotic cavity. Neutrophils, mi-croglia, and proinflammatory chemokines and cytokines initiate macrophage phagocytosis. Within a week, T-lymphocytes and circulating monocytes enter the region of injury. These cells move throughout the perilesional area for more than a month postinjury and contribute to further axonal damage by creating free radicals, cytokines, proteolytic enzymes, and other toxins.239 In addition, extracellular matrix molecules contribute to the glial scar. Cystic cavities within the central core of injury add a further barrier to the penetration of surviving axons. Injured axons retract.

Other Sources of Pain Associated with Cancer Other Conditions

As we've indicated, patients are sometimes fearful of admitting ongoing pain for fear that it means that their condition has worsened. This natural tendency toward denial underscores the importance of recognizing that not all pain associated with cancer means a tumor has grown or recurred or that the cancer has progressed. We have already discussed how treatment of the tumor can cause pain by injuring normal neighboring tissue scarring can also cause pain. Doctors sometimes call such discomfort be

Bone and Cartilage Healing

Unlike the healing by the scar formation of soft tissues, bone is capable of limited regeneration. As with the other tissues, the immediate response to injury includes inflammation and edema with associated bleeding in the marrow cavity and surrounding tissues (Fig. 3-2, A). Within a few days the fibroblas-tic phase of soft tissue healing begins and osteogenic cells from the periosteum and endosteum of the bone begin migration and proliferation at the wound site. These cells lay down callus and a fibrous matrix of collagen to form a bridge between two bony ends at the fracture site (Fig. 3-2, B). The osteogenic cells nearest the bone surface appear to transform directly into osteoblasts and lay down a collagen matrix that calcifies directly into bone (Fig. 3-2, C). The precise mechanism of calcification is not well known, but it appears that the collagen matrix, perhaps in interaction with the surrounding ground substance, initiates crystal formation and deposition.

Strategies to Relieve Pain

Even if pain isn't relieved, it doesn't mean a poor response to the antitumor treatment pain commonly persists even after very effective antitumor treatment (including surgery), especially when the tumor has produced scarring or fibrosis, or when its bulk has chronically stretched, bruised, or infiltrated nerves and other pain-sensitive structures. Sometimes powerful anticancer treatments produce their own new pain, an unfortunate complication.

Emergency Department Treatment and Disposition

Topical anesthetic drops (eg, 0.5 proparacaine or tetracaine) facilitate examination and removal. If superficial, removal with saline flush may be attempted before using a sterile eye spud or small (25-gauge) needle. Consider topical antibiotic drops or ointment for the residual corneal abrasion. Tetanus prophylaxis is indicated. A short-acting cycloplegic (eg, cyclopentolate 1 or homatropine 5 ) may benefit patients with headache or photophobia. FB or rust ring removal should be conducted using slit-lamp microscopy, only by a physician skilled in rust ring removal due to the risk of corneal perforation or scarring. Figure 4.8.

Blunt Abdominal Trauma

Uterine rupture is a rare (1 ) occurrence in blunt abdominal trauma when it does occur, it is usually in association with a fractured pelvis. The site of rupture is commonly the fundus of the uterus or the site of a previous uterine scar. Fetal mortality in such cases is 100 , and maternal mortality 10 35-38. Diagnosis may be difficult with vague abdominal pain, uterine tenderness, but with easily palpable fetal parts, and a poor trace or absence of a fetal heart on cardiotocography. Fetal demise and maternal shock are more dramatic presentations.

Smallpox and the Modern Rise of Population

Smallpox was long recognized as a contagious disease with a pustular rash. Distinctive clinical features, such as the simultaneous maturation of pustules (this distinguishes it from chickenpox) and the centripetal distribution of pustules over the body, were not noted. Oddly, the residual facial scarring among recovered variola major victims, was rarely mentioned. Nevertheless, by the early seventeenth century, smallpox was recognized by both lay and medical observers as a distinctive disease.

Thoracoscopic Transdiaphragmatic Adrenalectomy

Initially described by Pompeo et al. in a porcine model (89), this approach was further developed and the initial clinical series described by Gill et al. (12). In this series, the procedure was performed initially on four cadavers to develop the technique and then on three patients, all of who had significant abdominal scarring and prior ipsilateral renal surgery. After the placement of a double-lumen endotracheal tube, the patient is placed prone and a four-port transthoracic approach without pneumoinsufflation is used. Real-time laparoscopic ultrasound is used to identify the adrenal gland transdiaphragmatically. The diaphragm is incised, and the adrenal gland dissected. There were no intraoperative or postoperative complications, operative times ranged from 2.5 to 6.5 hours, and blood loss ranged from 50 to 500 mL (12).

Neuropathological effects of the blow

Later changes associated with the injury include raised intracranial pressure, secondary insult from extracerebral events, the systemic effects of multiple system injury such as hypoxia and fat embolism, degeneration of white matter (leukodys-trophy), disturbed flow of CSF hydrocephalus, and posttraumatic epilepsy from scar tissue formed during the injury. For example, in a study undertaken in Minnesota

Natural history of MCL injury

Healing of the MCL has been found to be a long and complex process that is subject to local and external influences. Generally, the process involves several discrete but overlapping phases the acute inflammatory or reactive response phase, the repair phase, and finally the tissue remodeling phase. In the acute inflammatory phase, the cellular and tissue responses to injury occur within approximately the first 72 h following a given insult. Capillary damage results in enhanced permeability of local blood vessels, allowing inflammatory cells to migrate into the tissue defect. Fibroblastic proliferation and the formation of scar matrix consisting of randomly aligned collagen and amorphous ground substance occurs simultaneously 66 .

Disease Source Material

Before 1743, influenza was frequently confused with other agues or catarral fevers. Diphtheria was not defined as a separate illness until the eighteenth century. Before that time, it was lumped with scar-letina or the purples. Because measles and smallpox both produced rashes, the two terms were used interchangeably until 1593. By 1629, however, when the Bills of Mortality were established, smallpox and measles were consistently differentiated. Smallpox was noted as flox or smallpox.

Laparoscopic Partial Adrenalectomy For Recurrent Pheochromocytomas

The author reported the first case of laparoscopic partial adrenalectomy for recurrent pheochromocytoma in the literature (52). Walz et al. demonstrated successful laparo-scopic surgical treatment of three locally recurrent pheochromocytomas following open transperitoneal surgery, including one case of partial resection (50). They noted limited scarring around the recurrent tumors allowing clear and rapid identification of landmarks and neoplasm, and recommended endoscopic surgery for recurrent pheochro-mocytomas in experienced hands. In the author's personal experience, laparoscopic partial adrenalectomy was attempted on seven recurrent tumors in five patients with hereditary pheochromocytoma and was successful in five (71 ). Total laparoscopic adrenalectomy was necessary in two cases (Table 1).

Periimplant Soft Tissue Optimization

The existence of pigmented gingival tissues warrants exercising care to avoid scar tissue formation, which would contribute negatively to the esthetic result, especially in high smile line patients. The continuity of the keratinized band should be preserved using less invasive therapeutic techniques, such as flapless surgical entries (See Figure 2.26A). Gingival components that contribute to an esthetically pleasing implant-supported restoration are the marginal radicular form, the interdental tissues status, and the color and texture of healthy keratinized tissues (Tarnow and Eskow 1995a). Figure 2.26A. An intraoral view showing scar tissue opposite to the upper left lateral incisor that leads to discontinuity of the keratinized band in pigmented gingiva. Figure 2.26A. An intraoral view showing scar tissue opposite to the upper left lateral incisor that leads to discontinuity of the keratinized band in pigmented gingiva.

Stimulate Axonal Regeneration

Reactive astrocytes in the region of an injury inhibit axonal sprouting, although these cells do protect nearby neurons and protect the blood-brain barrier.93 Oligodendrocytes and, more so, myelin degradation products especially inhibit regeneration. Myelin-associated glycoprotein94 and Nogo-A95 inhibit axonal regeneration in the adult CNS. MAG is found in uncompacted myelin and in the innermost membrane of myelin, where it contacts its axon. Nogo-A is a protein associated with the endoplasmic reticulum, so it too is exposed only after an injury. Both proteins inhibit the growth cone, perhaps especially when released from damaged oligodendrocytes.96 Thus, intact myelin may be less inhibitory than first considered. Indeed, Davies, Silver, and colleagues showed that in the absence of scar, normal and degenerating white matter in adult rats permitted rapid growth of axons from implanted embryonic neurons and from adult spinal dorsal root ganglia sensory neurons over long dis-tances.9798...

Special Considerations Previous Procedures

Seifman et al. reported on 190 patients, of whom 40 had undergone previous abdominal surgery. The authors found that the group with prior abdominal surgery was associated with longer hospital stay (3.8 days vs. 2.6 days) and higher complication rates (16 vs. 5 ). Specifically they reported that an upper midline and ipsilateral upper-quadrant scar were associated with a higher incidence of access complication (12 vs. 0 ) (9).

Skin and Subcutaneous Tissue

Thorough examination of the surface condition and contours of the extremity helps define pathology and influences splint configuration. Closely correlated with neurovascular status, tissue viability, and the inflammatory process are skin color, temperature, texture, and moisture. These should be carefully noted. Alterations from normal extremity size and contour should also be identified, including areas of atrophy, tissue deficit, scarring, local swelling, generalized edema, and abnormal masses or prominences. In addition to providing important information regarding condition of soft tissue and how the extremity is used, skin creases serve as anatomical guides for splint application. Absence of wrinkles or creases at or near joints may indicate loss of motion or inflammation, and callus formation or embedded surface grime are excellent clues as to how the extremity is used. Because the application of any splinting device, no matter how well fitted, produces pressure and shear to the...

Preventive Surgery for Multiple Endocrine Neoplasia Type 2 Gene Carriers

The thyroid C cells do not concentrate iodine, and reports of radioactive iodine treatment of metastatic MTC have indicated a lack of significant effect.54 Several reports have advocated the use of external beam radiation therapy for MTC.5558 These retrospective studies involved small numbers of patients, and it is difficult to determine whether or not radiation treatment had a significant effect. Other studies have not supported the use of radiation therapy in MTC.23,24,59 In the report by Samaan and colleagues, 202 patients were studied retrospectively. Even though the authors believed that the characteristics of the two groups were comparable, it was found that the patients who received external beam radiation therapy had a worse outcome those who did not.24 A study from France in 1992 reported a series of 59 patients with MTC, all of whom received external beam radiation therapy to the neck and upper mediastinum after surgery.60 Of these 59 patients, 44 had positive nodes and 11...

Finding our way through the white and the grey

If we look at the hemispheres in cross-section, the central portion appears lighter and is referred to as white matter. It appears white because of the presence of myelin, the insulator which allows nerves to conduct signals more quickly. (In diseases like multiple sclerosis, the myelin becomes damaged, seen as multiple patches of sclerosis or scarring throughout the brain.) Covering the white matter, like the rind of an orange, is the darker grey matter or cortex.

What are the risks of surgery How are they treated

A bladder neck contracture is scar tissue that develops in the area where the bladder and urethra are sewn together. This problem occurs in about 1 in every 20 to 30 prostatectomies. The signs and symptoms of a bladder neck contracture include decreased force of stream and straining (pushing) to urinate. The bladder neck contracture is identified during an office cystoscopy, in which a cystoscope, a telescope-like instrument, is passed through the urethra up to the bladder neck and the narrowed area is visualized. If the opening is very small, a small wire can be passed through it and the area dilated using some metal or plastic dilators. Before the procedure, the urethra is numbed with lidocaine jelly to decrease discomfort. Usually, once the bladder neck is dilated, it remains open however, in a small number of men, a repeat dilation or an incision into the scar under anesthesia is needed. A complication of treatment for bladder neck contracture is urinary incontinence. Scar tissue...

Associated Medical Findings

The skin should be checked for rashes, lesions, or evidence of insect bites. The head and neck should be examined for masses, signs of trauma, or postoperative scars. The auricle and ear canal should be examined thoroughly for vesicles, ulcers, or other lesions. The tympanic membrane should be checked for perforation, drainage, or cholesteatoma. Infections, neoplasms, and evidence of prior otological surgery should be sought while examining the middle ear. The oral cavity and pharynx should be checked for masses, ulcerations, fissuring of the tongue, and other lesions. The parotid should always be palpated for tumors and inspected for inflammation. If nonsuppurative parotitis, uveitis, and mild fever are found, Heerfordt's disease, a variant of sarcoidosis, may be present. Endocrinological function should be evaluated, because diabetes insipidus or other evidence of pituitary dysfunction can signify neurosarcoidosis. If there is incomplete eyelid closure, the cornea should always be...

What is brachytherapyinterstitialseed therapy Who is a candidate What are the risks

This narrowing of the urethra is related to the development of scar tissue and occurs in 5 to 12 of men, and tends to develop later. It may present with a change in the force of stream or the need to strain to void. A stricture is identified by cystoscopy in the doctor's office. Treatment of the stricture depends on the location and the extent of the stricture it may require simple office dilation or an incision under anesthesia.

Technical Modifications for the Management of Complex Renal Cysts

The branches of the renal vasculature and collecting system are often distorted and splayed by the peripelvic cysts, making them difficult to identify and differentiate from the cyst itself. Prior attempts at percutaneous drainage can also result in inflammation and scarring, making the tissue planes between the peripelvic cyst and hilar structures even less distinct. Placement of a ureteral catheter with retrograde injection of indigo carmine-or methylene blue-stained saline is useful in identifying the course of the splayed collecting system and for identification of collecting system injuries. Precise identification of renal vascular braches can be aided by the use of laparoscopic ultrasound with Doppler if available. Unlike with simple peripheral renal cysts, excision of the entire anterior cyst wall may not be feasible with peripelvic cysts. Overzealous attempts at cyst wall excision as well as cauterization of the cyst lining can lead to vascular and or collecting system injury.

Increase Axonal Regeneration

The major barriers to axonal regeneration include glial scar, molecules in the milieu that inhibit growth cones or are not available to attract growth cones, and a core of necrosis and dead space that cannot be traversed. Following a SCI in rodents, lesioned corticospinal tract axons from layer V pyramidal cells have regenerated into implants of neurotrophins, fetal tissue, peripheral nerve, and Schwann cell grafts, but tend not to extend beyond these stimuli into distal white matter. Olfactory en-sheathing cells have led to greater growth into white matter. Inosine enabled uninjured axons to sprout collaterals into normal white matter. Other axons, especially serotonergic and nora-drenergic fibers, have traversed longer distances after injury.

Molecules For Attraction And Repulsion

Antibodies to specific myelin-associated inhibitors of neurite growth have been given to rats after a partial SCI to prevent the milieu's inhibition of axonal regeneration.243 Schwab and colleagues first implanted hybridomas of plasma cells that made myelin-associated neu-rite inhibitors into the ventricular system of newborn rats lesioned with a hemicordectomy. The primary inhibitor was later characterized as Nogo-A.95,244 The antibodies increased ax-onal growth, although the fibers mostly skirted the surgical scar. Neurotrophin-3, but not BDNF injected into the lesioned rat spinal cord increased the regenerative sprouting of the transected corticospinal tract neutralizing the myelin-associated neurite growth inhibitory proteins resulted in regeneration of up to 20 mm.245 The axons generally did not pass Other approaches to neutralizing inhibitors derived from oligodendrocytes and myelin have shown similar success. A vaccine against extracts of myelin, for example, appeared to block...

Retroperitoneal Vs Transperitoneal Nephrectomy For Nonfunctioning Kidneys Due To Calculous Disease

The initial approach, retroperitoneal or transperitoneal, is the same as described for pyelolithotomy or ureterolithotomy. Subtle differences vary with the degree of perinephric inflammation encountered. In the absence of significant adhesions, we prefer to place the balloon inside Gerota's fascia because this allows rapid and easy dissection of the kidney. The hilum is then approached and the vessels clipped. Past history of pyelonephritis, evidence of renal scarring, perinephric adhesions, and pyonephrosis predominantly lead to dense perinephric adhesions which preclude safe and easy dissection, as the kidney is densely adherent to the posterior abdominal wall. Open conversions typically occur due to excessive bleeding and poor intraoperative progress. Because the adhesions are per-inephric, the space external to Gerota's fascia is still relatively clear. The hilar vessels are approached first to minimize bleeding during the subsequent dissection of the kidney. It is important to...

Resection or Complete Lobectomy

The strap muscles are reapproximated, as is the platysma, with interrupted or continuous absorbable sutures. The skin may be closed by subcuticular suture, or with the use of special broad clips removed after the first or second day, and Steri-Strips placed. Whichever technique is used, it should be done carefully scars in this area can and should be almost invisible. When it is necessary to divide the sternohyoid or sternothyroid muscles, or both, this should be done in the top of the wound to avoid scar fixation and to denervate less muscle, because the ansa hypoglossal nerve innervates these muscles inferiorly.

Clinical Presentation

For patients with symptoms or with a positive PPD, chest radiograph and sputum cultures for AFB are required. Typical chest x-ray findings include hilar or mediastinal lymph-adenopathy, patchy infiltrates, apical scarring, and pleural effusions, but a cavitary lesion or miliary pattern (typical millet-seed granulomas scattered diffusely throughout lung fields) more specifically suggests TB.

What problems have been associated with the use of halo orthosis

Complications associated with use of a halo orthosis include pin-loosening, pin-site infection, discomfort secondary to pins, scars after pin removal, nerve injury, dysphagia, pin-site bleeding, dural puncture (following trauma to the halo ring), pressure sores secondary to vest irritation, reduced vital capacity, brain abscess, and psychological trauma.

Extra Humps and Their Timing

The normal apical impulse has a single outward movement, which is palpable. The rise in left ventricular wall tension during the end of diastole caused by atrial contraction, which may be recorded even in the normal subjects by sensitive instruments (A wave in the apexcardiogram), is not palpable (Fig. 7A). However, in patients with decreased ventricular compliance (stiff ventricles, which offer resistance to expansion in diastole), the atrium compensates for this by generating a stronger or forceful contraction, resulting in higher pressure. This produces an exaggerated A wave, which may become palpable as an extra hump, giving a double apical impulse, also called an atrial kick or hump (9,23). While this corresponds to an audible fourth heart sound (S4), it is not a palpable S4. This type of double apical impulse is easily recognized at the bedside as a step or hesitation in the upswing of the apical impulse. It can also be brought out by holding a tongue depressor over the apical...

Clinical Features

Although any body part or aspect of physical appearance may be a source of concern and several body parts may be involved simultaneously, concerns generally focus on the patient's face or head (e.g., size or shape of the nose, eyes, lips, teeth, or other facial features thinning hair excessive facial hair acne wrinkles scars). Individuals may spend hours per day checking their appearance, engage in excessive grooming or exercising to minimize or erase the defect, and or become housebound.

Who Are Good Candidates

The best candidates are men who are relatively young and who do not have severe forms of prostate cancer. Cryotherapy is also commonly used for individuals who have been treated with radiation but whose cancer has recurred. Surgery cannot be performed on most men who have already had radiation treatment, because the radiation destroys anatomical landmarks and causes scar tissue to form cryotherapy is therefore one of the few options available. In order for it to be effective, the cancer must be confined to the prostate men with advanced cancers are not candidates. Men whose prostate weighs more than approximately 40 gms are also not appropriate candidates unless the prostate can first be downsized with hormone therapy.

Introduction of New Diseases

The history of smallpox in East Asia reveals a curious chronology in the transmission of this disease. Of particular interest is the fact that smallpox is documented much earlier in the ancient civilizations of the West. Egyptian mummies 3,000 years old have been found with scars that resemble the typical pockmarks left by smallpox and the people of ancient Greece, as well as the people of India, are believed to have been afflicted with this disease before 400 B.C. The much later documentation of smallpox in China suggests that smallpox spread to eastern Asia from the West - a journey, if estimates of when smallpox reached China are even close to being correct, that took more than a thousand years.

Describe prolotherapy and its use in LBP

Prolotherapy treats back pain that is related to motion and due to weakened or incompetent ligaments and tendons. The injury-repair sequence is initiated by scraping the tissue or adjacent periosteum with a needle and then injecting a dextrose solution to induce fibroblast proliferation and scarring repair of tissue. Prolotherapy can increase tendon size and strength. Success (less pain, less tenderness) in patients with chronic LBP who have not responded to conventional treatment is reported.

The missing arm that hurts

The shrinking of the phantom limb observed after an amputation in humans is paralleled by the shrinkage of the brain representation of the fingers of a monkey after cutting their sensory nerves. These two observations are related because the image of the body stored in the brain is maintained by the incoming sensory messages. When the messages are discontinued, the brain image of the isolated or amputated part slowly shrinks, because the brain region is invaded by nerve fibers and messages from other areas, such as the face. However, if the scar in the stump irritates the severed nerves and produces pain, the phantom limb tends to persist. The changes in the brain sensory areas and in the subjective perception of the arm illustrate that the brain is plastic and is in a constant state of reorganization. The plasticity of the brain is one of its most remarkable characteristics and illustrates the tight relationship between form and function. These observations have been repeatedly...

Nuclear Perfusion Tests

If both tests show adequate blood flow, the heart and coronary arteries are probably normal. If both sets of scans show a defect, or an area of the heart where there is no uptake of thallium, this indicates that the muscle has probably been replaced by scar tissue from a previous heart attack. If the scan shows faint uptake of thallium during exercise but more normal uptake at rest, it indicates that the heart muscle in that area is probably still alive but the coronary artery may be blocked. In this case, a cardiac catheterization can identify the exact area of blockage.

Positron Emission Tomography or PET Scanning

PET can also tell if an area of the heart is not performing normally because it has been damaged during a heart attack and has now turned to scar tissue. In that case, there would be no need to place a bypass graft to an area that is never going to function normally anyway.

Laparoscopic Technique

Decompress the bladder and stomach, respectively. In the absence of a previous midline scar, access and insufflation are accomplished with a Veress needle using conventional laparoscopic techniques. Once pneumoperitoneum has been achieved, a 3-trocar transperitoneal approach is used. The placement of trocars is similar to a laparoscopic pelvic lymph node dissection (Fig. 1). A 12-mm trocar is placed for use by the camera along with an additional 12-mm trocar for potential use of a clip applier. A 5-mm trocar is placed for laparoscopic instruments. The peritoneal cavity is inspected for adhesions. Careful attention should be paid to check whether the adhesions will complicate marsupialization of the lymphocele and potential mobilization of the omentum. Identification and extent of the lesion may be facilitated by a percutaneous needle or catheter placed into the lymphocele either by preoperative or intraoperative ultrasound guidance. Often the lymphocele appears as a blue-tinged dome...

Functional Neuromuscular Stimulation

Short-term or intermittent stimulation sessions employ surface electrodes with low impedances placed over muscles. Long-term stimulation for daily use is most practical using electrodes implanted near each muscle's motor point with connecting wires that run under the skin to the stimulator. Implanted electrodes are designed for easy placement, immobility once in the contracting muscle, minor tissue responses to prevent infection and scarring, and durability. Electrodes designed for injection by a hypodermic needle under fluoroscopy must be quite thin and have barbs to keep them in place. Surgically implanted electrodes can be thicker and more durable and placed in the muscle or sewn onto the epimysium. A wireless, injectable electrode called the BION was released in 2000 to evaluate its utility in clincial applications (Advanced Bionics Corp, Sylmar, CA A.E. Mann Foundation for Scientific Research, Santa Clarita, CA).5 The ceramic case is approximately 2.5 mm wide and 15 mm long. It...

Multiple choice questions

D Treatment with anti-inflammatory drugs reduces the risk for myositis ossificans (after hip arthroplasty). e When left unchecked it can lead to a chronic situation and destruction of tendons and surrounding tissue resulting in ruptures of tendons, scar tissue and adherence.

Interpretation of physical impairment

To interpret this scale we must look again at the definition of impairment. This is a pragmatic method based entirely on clinical findings. It does not depend on pathologic or clinical diagnosis. Our previous study showed that the only permanent lumbar impairments were structural deformities, fractures, surgical scarring, and neurologic deficits. None of these apply to the patient with non-specific low back pain, and they do not appear in the present scale. This method provides an objective clinical evaluation, but it is not a measure of anatomic or structural impairment. Instead, all the tests in our scale are really measures of physical function. They are functional limitations associated with pain or disuse. More graphically, they are measures of inability to do because of pain. It is a matter of perspective whether we regard these findings as physiologic impairment as in the WHO definition or as clinical observations of performance. In any event, performance in these tests depends...

Vaginal Birth after Cesarean

Previous cesarean delivery, adequate pelvis, no uterine scars, and immediate availability of both a physician to perform an emergency cesarean delivery and facilities and anesthesia to support an immediate cesarean delivery. Use of pros-taglandin cervical ripening is discouraged in these women because of the small increased risk of uterine rupture associated with these medications when used with a scarred uterus. After careful patient selection, preparation, and management, 7 or 8 of 10 women with uterine scars deliver vagi-nally. The strongest predictor of the safety of VBAC is the location of the previous uterine scar. Safety of TOLAC in women with history of one cervical low-transverse cesarean has been documented. Rupture of these incisions is low,

How are trial spinal cord stimulation electrodes placed

Some physicians prefer placing plate-type electrodes for the trial implant, especially if there is scarring in the epidural space following prior spinal surgery, which can make placement of catheter type electrodes challenging. Plate-type electrode placement can be performed either under mild sedation in combination with local anesthesia or under general anesthesia with the patient awakened during the procedure for testing. The trial period may last days to weeks, but trial periods beyond 3 to 5 days require that the leads be tunneled under the skin from the insertion site to decrease the risk of infection.

Videolaparoscopyassisted Implantation Of Continuous Ambulatory Peritoneal Dialysis Catheter 5162

Historically, this procedure has been performed under general anesthetic because a pneumoperitoneum with CO2 gas is not well tolerated by patients. Subsequently, this procedure has been modified by Giannattasio et al. and Crabtree and Fishman and can now be performed under local anesthesia with nitrous oxide gas and intravenous sedation. Currently videolaparoscopy is used more due to many benefits such as lower risk of trauma, short recovery time, short hospital stay, and small surgical scar (51).

Total Glans Resurfacing TGR

There are several advantages of using the technique of TGR. Unlike any other treatment, an undamaged histological specimen is obtained to confirm complete excision of the disease. This is important when dealing with a prema-lignant condition. Given that the glans and sub-coronal epithelial and subepithe-lial tissues are completely excised, the chance of local recurrence is minimal, although long-term follow-up is still required. Moreover, TGR restores normal anatomy with minimal scar tissue formation. It appears particularly suitable for younger men in whom there is minimal operative risk, and in whom cure is paramount.

What is the Arnold Chiari malformation

The Arnold-Chiari malformation is a developmental anomaly in which the brainstem and cerebellum are displaced caudally into the spinal canal. In Type 1 Arnold-Chiari malformation, the cerebellar tonsils are displaced into the cervical spinal canal. This malformation is associated with other cervical anomalies including basilar impression and Klippel-Feil syndrome. Dense scarring at the level of the foramen magnum may lead to hydromyelia or syringomyelia. Type 2 Arnold-Chiari malformation is a more complex anomaly and is usually associated with myelomeningocele. Cerebellar displacement is accompanied by elongation of the fourth ventricle, as well as displacement of the fourth ventricle and cervical nerve roots.

A woman may also present with amenorrhea. The four most common causes of secondary amenorrhea (when a woman who previously had normal menses stops having menses for at least 6 months) are pregnancy, hyperprolactinemia, thyroid disorders, and iatrogenic (from medications). Other reasons for amenorrhea include outflow obstruction (e.g., Asherman's syndrome, caused by scarring of uterus from instrumentation, or cervical stenosis) and primary ovarian failure. Evaluation of a woman with amenorrhea begins with a history and physical examination. Laboratory studies should include a pregnancy test and thyroid-stimulating hormone (TSH) and prolactin levels. The next step is an induced withdrawal bleed after administering progesterone for 10 to 14 days. If a woman has a menstrual bleed after the progesterone, outflow obstruction and low estrogen state

Heart Attack and Heart Failure

In the event a patient survives a large heart attack, a considerable portion of heart muscle will turn into scar tissue and no longer contract. This can lead to heart failure. The patient will become short of breath and frequently fatigued because of the reduced amount of blood being pumped by the heart, resulting in a relative lack of oxygen and other nutrients getting to the body's tissues. The patient may develop swelling in the ankles or in the legs or abdomen as the heart fails and fluid backs up into the tissues.

Thumb Ligament Injuries

Complete ruptures of the UCL less than 2 months after injury can usually be addressed by careful excision of scar and reinsertion of the retracted ligament.45 Chronic UCL injuries have been treated by using a scarred capsule to create a new ligament, adductor advancement, or reconstruction with a free tendon graft.45,50,51 The postoperative rehabilitation is similar to that for acute repair. However, an additional 1 to 2 weeks of immobilization is recommended. MP arthrodesis may also be considered to address chronic UCL insufficiency. Partial RCL tears are treated with immobilization in a hand-based thumb spica cast or splint for approximately 4 weeks. Mobilization of the MP joint is initiated at 1 month with continued splinting for an additional 2 weeks. Athletes are protected with splint or taping for 10 to 12 weeks after injury. Both immobilization and early repair have been advocated for the treatment of complete ruptures of the RCL.45,52,53 Physical...

Cardiac Conduction System

Myocardial cells are specialized cells designed to shorten when activated by a threshold electrical stimulus, thus providing mechanical force to produce contraction. The cell membrane is characterized by fast, sodium channel activation. Depolarization of the cell results in release of sarco-plasmic calcium and cardiac cell contraction. Conduction velocities are intermediate between SA and AV nodal cells and the Purkinje cells. Cell death, injury resulting in scarring or functional conduction slowing, or changes in cellular automaticity may result in clinical arrhythmias (Zipes, 1992).

Other Disorders Of Neuronal Migration And Cortical Formation

Ulegyria is another distinct cortical anomaly. Ulegyria is best characterized as a fusion of layer 1 at the depths of sulci with relative sparing of the crests of the gyri. The fusion is frequently associated with gliosis in the cortex, neuronal loss, and obliteration of the cortical lamination. The scarring at the depth of a sulcus and sparing at the surface of the brain results in a mushroom appearance when the gyrus is viewed on cross section. These lesions have very well-defined borders and discrete islands of preserved neurons within the lesion. The histology and location, frequently in an arterial zone, have led to the contention that ulegyria arises late in gestation or in early neonatal life as a vascular injury to the immature cortex, possibly related to hypoperfusion. Ulegyria may be clinically silent or manifest as seizures, similar to those of polymicrogyria discussed earlier.

Reconstruction in the head and neck region

Wound healing by a mixture of contacture and re-epithelialisation. One problem with laser excision is that any resection specimen will have thermal damage and pathological examination of margins will be impossible. In theory, scarring is less and, if selection of the tumour is correct, then function will be minimally affected. Re-epithelialisation is most effective where there is no possibility of contracture. Raw surfaces can be left in the hard palate, for example, which will re-epithelialise over a period of time.

Preservative Interproximal Papilla Incision

A complete mobilization of the flap is required when major bone-grafting procedures are conducted. Then a mucoperiosteal flap that includes the interproximal papilla might be undertaken to allow for better access, bearing in mind that the vertical incision should be as far as possible from the area of interest to provide a better blood supply to the flap, reduce the tendency for suture rupture, and reduce the tendency for scar tissue formation, as shown in Figures 5.10A-C.

Advantages and Disadvantages

The advantage of the cosmetic outcome is generally considered obvious because a scar of 1 to 2 cm tends to be better accepted than a 4- to 6-cm scar in the same region. Patients' satisfaction evaluated in a prospective study by means of a visual analog scale score proved to be significantly better in a minimally invasive video-assisted parathyroidectomy versus a conventional procedure.19

Neurogenic and Vascular Tumors of the Head and Neck

In most cases, the surgical excision of all but the most pedunculated, cutaneous hemangiomas that are in a location that permits excision with camouflage of the surgical scar is questionable. The exception to this is that of periorbital hemangioma previously alluded to whose excision is considered a surgical emergency.3 In the case of subglottic hemangiomas requiring treatment for airway compromise, the initial role for surgery may be in the establishment of an airway via a tracheostomy, with laser excision only considered for small, well-circumscribed lesions secondary to the risk of subglottic stenosis.8,10 In the rare situation where an intramuscular hemangioma is suspected of causing functional compromise secondary to the compression of adjacent structures, surgical excision can be accomplished, keeping in mind the higher rate of recurrence of these tumors secondary to their more infiltrative pattern of growth.6

RS Williams and P Rosenberg

Hypertrophic hearts are susceptible to abnormalities of cardiac rhythm, and have impaired relaxation (diastolic dysfunction), although contractile performance can be preserved. However, when hypertrophic stimuli are unrelieved, the remodeling phenomenon progresses to dilated cardiomyopathy and increasing degrees of replacement of cardiomyocytes with fibrotic scar, and circulatory failure ensues. Morphological hypertrophy occurring in response to pathological stimuli is associated with changes in gene expression, prominently including the reactivation of genes expressed normally in the fetal heart but silenced in the adult heart (Hill et al. 2002 Williams 2002).

Inhibitors of axon regeneration

Contains multiple myelin-associated inhibitors of axon outgrowth and regeneration (Volume I, Chapter 21). Identified inhibitors include myelin-associated glycoprotein (MAG), oligodendrocyte-myelin glycoprotein (OMgp), and Nogo (McKerracher et al., 1994 Mukhopadhyay et al., 1994 Chen et al., 2000 GrandPre et al., 2000 Prinjha et al., 2000 Kottis et al., 2002 Wang et al., 2002). MAG is a transmembrane Ig superfamily member expressed by myelinating glia in the PNS and CNS. OMgp is a GPI-linked membrane protein component of CNS myelin. Nogo is expressed by oligodendrocytes, but not Schwann cells, and is the protein recognized by IN-1, a monoclonal antibody that enhances axon outgrowth on substrates of myelin in vitro and promotes axon regeneration in the mammalian CNS (reviewed in Schwab and Bartholdi, 1996). Remarkably, these three structurally unrelated proteins all interact with the same cell surface receptor, NgR, a GPI-linked membrane protein widely expressed by neurons that was...

Pharmacologic Therapy

Topical corticosteroids are employed in some cases of bacterial keratitis. The suppression of inflammation may reduce corneal scarring. However, local immunosup-pression, increased ocular pressure, and reappearance of the infection are disadvantages to their use. There is no conclusive evidence that they alter clinical outcomes. If the patient is already on topical corticosteroids when the keratitis occurs, discontinue use until the infection is eliminated.

Inlay Tissue Grafting

In esthetically demanding areas where only increased tissue height is required, no vertical relaxing incisions should be made at the recipient site to avoid any possibility of future scar tissue formation. Connective tissue grafts can be applied to the recipient site in a pouch-like shape. These are used to correct confined minor ridge deficiencies, where the color and surface characteristics of the area after grafting should not differ from the orig-

Clinical Manifestations

Pelvic Inflammatory Disease (PID) Perhaps the major modern concern about gonorrhea is its potential for destruction of female reproductive organs. The gonococcus may spread upward from the cervix to inflame the uterine lining of the fallopian tubes (salpingitis) and ultimately cause peritonitis. Once established, PID becomes chronic, of long duration, and with serious consequences. Approximately 20 percent of women will have a recurrence after treatment for a primary episode of gonococcal PID. The syndrome of chronic pain, lower abdominal discomfort, and dyspareunia reflects insidious scarring and closure of the fallopian tubes, which may cause ectopic pregnancy and lead ultimately to involuntary infertility. Studies in Sweden indicate that the risk of sterility is 12 to 16 percent after a single episode of salpingitis and rises to 60 percent after three episodes. The other major mode of transmission of the gonococcus is from mother to child. A newborn may become infected during...

Epidemiology and etiology

A spectrum of acne lesions is seen on the face of a 17-year-old male comedones, papules, pustules, and erythematous macules and scars at the site of resolving lesions. The patient was successfully treated with a 4-month course of isotretinoin there was no recurrence over the next 5 years. (From Wolff K, Johnson RA. Disorders of sebaceous and apocrine glands. Fitzpatrick's Color Atlas & Synopsis of Clinical Dermatology. 5th ed. New York McGraw-Hill, 2005 5.) (From Ref. 2.) FIGURE 65-1.

Risk Factors and Etiology

Trauma most often draws attention to an existing tumor, but there is no conclusive evidence to support the association of sarcomas to scar tissue. Risk factors for chondrosarcomas are thought to include the presence of pre-existing multiple chondromas or osteochondromas while predisposing factors for osteosarcoma include a history of retinoblastoma and genetic factors, Paget's disease of bone, fibrous dysplasia, and previous radiation therapy.

Etiology and Epidemiology

Infection with the herpes simplex virus results from person-to-person contact. HSV-1 infections commonly are transmitted by oral secretions through kissing or the sharing of eating utensils, and thus herpetic infection can easily be spread within a family. Normally HSV-1 infections are painful and bothersome but have no serious consequences. An exception can be when the virus invades the cornea of the eye. Conjunctival or corneal herpes may produce scars that impair vision. It may occur among wrestlers from skin-to-skin contact. Another form of HSV-1 infection, called herpetic paronychia, may occur in dentists and in hospital personnel.

Surgical Treatment And Outcome

Postoperative neurologic improvement has been noted in 50 to 80 of patients in large series.3,17,23 Outcomes are favorable even in the case of patients with paraplegia.17 Features of en plaque tumors such as significant arachnoid scarring and invasion of the spinal cord parenchyma prevent complete resection. Extradural tumors can have unfavorable prognosis because of their invasiveness and their vascular nature and aggressive clinical course.17 Predictors of poor outcome also include long duration of symptoms before diagnosis, profound neurologic deficits, subtotal tumor removal, and old age.24

Pathophysiology of Achilles Tendinopathy

Histologic examination of the peritendinous structures reveals the presence of both fibroblasts and myofibroblasts, comprising up to 20 of the peritendi-nous cells in chronic paratendinopathy.54-56 Under mechanical strain, fibroblasts secrete TGF-P that follows a paracrine mechanism to induce tenocyte metaplasia into myofibroblasts, resulting in peritendinous tissue scarring and contraction. This causes a constrictive effect on the local circulation that may leave an area of relative tendon hypovascularity.

Large Number Of Different Skin Diseases

The term acne refers to a group of disorders characterised by abnormalities of the sebaceous glands. Acne vulgaris is the most common condition and is characterised by polymorphous lesions, including comedones (blackheads), inflammatory lesions such as papules or pustules, and scars, affecting the face and less frequently the back and shoulders. A combination of factors are considered as pathogenetic, including the hormonal influence of androgens, seborrhea, abnormalities in the bacterial flora with overgrowth of Propionibacterium Acnei, and plugging of pilosebaceous openings. Mild degrees of acne are extremely common amongst teenagers (more than 80 ) and decrease in later life. The prevalence of moderate to severe acne has been estimated at about 14 in 15-24 year-olds, 3 in 25-34 year-olds and about 1 in 35-54 year-olds. It is likely that the vast majority of sufferers of mild acne do not seek medical advice. Around 70 of those affected with acne experience shame and embarrassment...

Uterine abnormalities

Abnormalities of uterine vasculature such as arteriovenous malformations and false aneurysms may also lead to secondary postpartum hemorrhage. Arteriovenous malformations are due to an abnormal communication between an artery and vein with proliferation of each vessel with interconnecting fistula. It is believed these malformations may result from venous sinuses becoming incorporated in scars within the myo-metrium after necrosis of the chorionic villi. The majority are acquired after pregnancy and may result from trophoblastic disease, previous uterine curettage, uterine or cervical malignancy8,9 or Cesarean section10,11. Diagnosis is made using ultrasound with color Doppler analysis.

Table 283 Causes Of Postmastectomy Patn And Symptoms

Keep the arm in a flexed position close to the chest wall. The intercostobrachial nerve has been reportedly injured in 80 to 100 of mastectomy patients undergoing axillary dissection and has been described as the cause of the axillary and upper arm pain.73 Phantom breast pain occurs in 10 to 64 of women, with most of the phantom pain and sensations reported in the nipple. This is because the nipple is the most highly innervated breast tissue. It is supplied by the fourth intercostal nerve.173 Other causes of postmastectomy pain include damage to the long thoracic nerve, leading to denervation of the serratus anterior muscle winged scapula and musculoskeletal pain in the shoulder girdle damage to the thoracodorsal nerve, leading to denervation of the latissmus dorsi and musculoskeletal pain and mastectomy scar sensation, which is described as painful and dysesthetic. 013 Table 28-3 summarizes the causes of postmastectomy pain. The incidence of chronic post-thoracotomy pain ranges from...

Cesarean section wound dehiscence or surgical injury

Surgical injury to pelvic blood vessels at the time of Cesarean section10 usually presents within 24 h. However, later presentations, in particular those causing broad ligament hematomas, have been described5 and should be considered in women presenting acutely with signs of intra-abdominal hemorrhage. Delayed presentation of bleeding from non-union dehiscence of the Cesarean section uterine scar has also been described. This is believed to be due to local infection at the site of uterine closure causing erosion of blood vessels. In the

Causes of Mitral Regurgitation

The leaflet may be congenitally cleft, and this abnormality may be seen in association with ostium primum atrial septal defect (40). The leaflets may also be congenitally large and redundant and may show overhanging hooded or prolapsed appearance because of myxomatous degeneration (49,50). The chordae may also be excessively lengthened as well as showing some thickening. The chordae could rupture spontaneously if the elastic fibers are significantly destroyed because of myxomatoaus degeneration. The leaflets, on the other hand, may be contracted and scarred because of repeated inflammation, as may happen with rheumatic involvement. They may eventually show areas of calcification. The chordae that are scarred and shortened will prevent proper leaflet closure. In addition, the commissures may be fused, resulting in varying degrees of stenosis. In infective endocarditis, the infective process could cause destructive lesions in the leaflets or the chordae besides formation of vegetation....

Robot Assisted Laparoscopic Radical Cystectomy

250 mL and hospital stay, 7.3 days (21). Menon et al. reported technical feasibility of nerve-sparing robot-assisted radical cystectomy with extracorporeally created urinary diversion in 14 men and 3 women (22). Mean blood loss was less than 150 mL, and operative time for robotic radical cystectomy, extracorporeal ileal conduit, and extracorporeal orthotopic neobladder were 140, 120, and 168 minutes, respectively, although 13 (76 ) patients had associated bilharziasis, with significant periureteric, perivesicular, and perivesical scarring. The functional and oncological data in this series were awaited.

Spiritual and Existential Health

There is no doubt that religion also has the potential to go very wrong and to play a destructive role in terms of mental health. Religion is easily contaminated by individuals in authority who twist the process in order to accommodate their own perversions, control ambitions, and eccentric interpretations. Additionally, it is possible for religions to incorporate beliefs and worldviews that can prove disturbing to members, and ritual practices that are sometimes the source of emotional scarring, but the fact that all cultures throughout history have created religion speaks to some extent of religion's capacity to afford members with certain benefits. Even so, modernity has ushered in dramatic changes that have important implications for religion's ability to function as a mental health prophylactic.

Concept of Doubledoor Laminoplasty

Until the 1970s, laminectomy had been the sole therapeutic option for posterior decompression of the spinal cord. However, wide laminectomy of the cervical spine sometimes caused early or late neurological deterioration (or both). The possible causes of such deterioration were the progression of malalignment such as kyphosis or listhesis, postoperative progression of ossification of the posterior longitudinal ligament (OPLL) associated with malalignment and instability of the cervical spine in patients with OPLL, and massive scar formation in the epidural space, known as postlaminectomy membrane 1-4 . To resolve the problems associated with laminectomy, several variations of laminoplasty have been developed in Japan and used instead of laminectomy 5-7 .

Treatment Options And Recommendations

Most authors now recommend surgical intervention for all acute injuries resulting in severe tibial subluxation and for combined multiligamentous injuries.1,6,10 Surgery is also recommended for avulsion injuries with translation greater than 10 mm. If the fragments are small, the PCL should be reconstructed, but if the fragments are sufficiently large, internal fixation may be attempted. Combined injuries are best treated within 2 weeks, after which capsular scarring develops and direct repair of collateral and posterolateral corner structures is usually not possi-ble.9 ACL reconstruction may be delayed, however, in order to regain knee motion and allow capsular healing. Multiple surgical options exist for ligament reconstruction, including choice of graft, single- versus double-bundle techniques, and tibial tunnel versus tibial inlay techniques. These are discussed in more detail in the next section.

Single Bundle versus Double Bundle Techniques

Tubercle through a longitudinal 2- to 3-cm incision. This results in a trajectory of 50 to 60 degrees to the long axis of the tibia, creating a graft orientation at the posterior tibia of approximately 45 degrees. This reduces the effects of the killer turn, a term referring to the sudden bend that the graft must take as it passes from the tunnel into the knee joint.10 The anterior skin incision can also be placed lateral to the tubercle, which may further reduce graft angulation.21 It has been recommended that one make a 2-cm safety incision posteromedially, which will allow access for the surgeon's finger to directly protect the neurovascular structures and monitor any instruments placed in posterior knee10 (Fig. 53-14). A guidewire is drilled under arthroscopic visualization, and a 10- to 12-mm tunnel then drilled over the wire, taking care to protect the neurovascular structures at all times because, even with the knee flexed 90 degrees, the distance between the popliteal artery...

Transtibial versus Tibial Inlay Techniques

It is sometimes difficult to pass a graft around the sharp angle at the back of tibial tunnel, and this bend poses several potential long-term disadvantages tibial tunnel erosion may occur, excessive bending may increase graft strain and wear, and the abrasive ridge may lead to elongation, fraying, or failure.23 Drilling of the tibial tunnel also risks neurovascular injury. Furthermore, the tibial tunnel technique requires a longer graft (usually at least 40mm), which may be a problem, especially when using bone-patellar tendon-bone grafts. The tibial inlay method is an alternate technique that uses direct exposure and visualization for tibial fixation, eliminating the acute turn because the graft is fixed directly to a trough on the posterior tibia via a bone block. This is theoretically more secure, allows use of a bone-tendon or bone-tendon-bone allograft with bone-to-bone healing and may improve isometry. However, patient positioning is more difficult, as is hardware removal if...

Squamous Cell Carcinoma

Cutaneous squamous cell carcinoma is the second most common form of skin cancer, also arising primarily on sun-exposed skin of middle-aged and older adults. Most SCCs arise from sun-induced precancerous lesions (actinic keratoses). As in BD, there is a higher risk of SCC in patients with radiation dermatitis (x-ray damage), leukoplakia or erythro-plakia (in oral or genital mucosa), burn scars, and chronic skin ulcers. It is important to note that organ transplant recipients have a 40 to 250 times greater risk of developing SCC, purportedly from interaction of HPV and immuno-suppression.

What is Peyronies disease and what causes it

Peyronie's disease is a benign condition of the penis that tends to affect middle-aged males. The exact cause of Peyronie's disease is not known. The disease is characterized by the formation of plaques in the tunica albuginea of the penis. These plaques may be felt on penile examination and at times can feel as hard as bone. The plaques are like scar tissue and affect the function of the tunica in that area. Because the plaque is not elastic and stretchy like the rest of the tunica, it pulls the penis to the side of the plaque during an erection and may also cause wasting narrowing at the site of the plaque. There may also be pain associated with an erection. Lastly, because the plaque does not behave like normal tunica, it may also cause erectile troubles. The plaque may occur anywhere along the penile shaft but is more commonly identified on the top (dorsal) surface of the penis. More than one plaque may be palpable. The hallmarks of Peyronie's disease are a palpable plaque (a hard...

Management of the Groin in Clinically Node Positive cN Patients

Suspicious enlarged node the surgeon should pay attention to the anatomical localization of the inguinal incision, as the inguinal scar should be removed at the time of completion inguinal lymphadenectomy. Patients presenting with fixed inguinal nodes are candidates for neoadjuvant chemotherapy prior to undergoing surgery.64

Preserving Biological Soft Tissue Contours

Several methods are used to guide the peri-implant tissues to their optimal contour with a provisional restoration immediately after implant installation or exposure (El Askary 2001). A novel method is used to improve the esthetic outcome of dental implants and to stabilize soft tissue margins. It might also stimulate gingival creeping in an incisal direction, which in turn improves many unfavorable clinical conditions. The method is used when immediate implant therapy is being conducted, by applying an immediate, delayed, or nonfunctional type of loading. This method is aimed at preserving natural tissue contours post-operatively, and was developed to avoid the resultant soft tissue complications from attempting soft tissue closure in the first-stage surgery, after which resultant scar tissue and altered mucosal continuity have been observed (Rosenquist and Grenthe 1996). This is especially true in patients with thin scalloped tissue biotype, which

Paramedian Forehead Flap

Blood supply is provided by branches of the facial, infraorbital and angular vessels. Superiorly-based nasolabial flaps are more useful for reconstruction of small-sized nasal defects, due to easier transposition. The inferiorly-based pedicle flap is often advanced in a V-Y fashion for cheek or upper lip defects (Figure 18-15).20 Nasolabial flaps are usually elevated in a superficial subcutaneous plane that excludes the main vascular pedicle. The donor site is usually closed primarily, with the scar concealed within the skin fold. Sometimes a secondary revision may be needed. Bilateral nasolabial flaps, based on the facial artery and vein, have been used to resurface floor of mouth and intraoral defects.21,22

Muscle And Musculocutaneous Flaps

The PM flap has been used to resurface cervical, facial, intraoral and pharyngeal defects (Figure 18-18).39-44 Although it can reach as far as the orbit, the most distal part of the flap may be compromised due to limited arc of rotation. In addition, it is often too bulky for intraoral reconstruction where thin, pliable tissue is needed to replace intraoral lining. The donor site may be closed primarily however, a very noticeable scar and nipple-areola distortion is often observed. Large or multiple skin islands may result in the need for donor site skin grafting.

Latissimus Dorsi Flap

The vertical trapezius flap has a wider range of transfer in the head and neck area than other flaps (see Figure18-21). Its blood supply comes from the dorsal scapular artery, originating from the descending branch of the transverse cervical artery, near the cranial border of the scapula or emerging directly from the subclavian artery. It descends vertically midway between the vertebral column and the medial border of the scapula, where the skin island of the flap usually is centered. Its caudal end may extend beyond the muscle and has a random blood supply. The skin island may be as large as 9 x 20 cm. The donor site may be closed primarily if it is less than 9.0 cm wide however donor site healing in this area is frequently associated with seroma formation and a very noticeable scar. This flap has been used for reconstruction of defects centered around the orbit and upward to the skull, across the midline, or for intracranial reconstruction. Although color match and texture of the...

Management of dysfunction syndrome

The treatment of adhesions, contractures or adaptive shortening as in an articular dysfunction essentially requires the application of movements that encourage the process of remodelling. Only with the application of such loading strategies will normal tissue function be re-established. Ideally such movements commence during the stages of repair and remodelling in the weeks after an injury (Evans 1980 Hardy 1989 Hunter 1994 Barlow and Willoughby 1992). If appropriate and graded tension is applied to injured tissue during the proliferative and remodelling phases of healing, adhesions and contractures will not form and dysfunction is prevented. The longer the time lapse between repair and the initiation of the recovery of full function, the more consolidated the scar tissue. Thus the task of remodelling will be more difficult and the time to recovery will be longer. Once the scar tissue is well consolidated, the very nature of the abnormal tissue prohibits a rapid recovery of function....

Instructions to all patients with dysfunction syndrome

Patients will be attending the clinic with pain. To be told that they must go away and regularly cause the pain that they are complaining about needs a very good explanation to gain their adherence to the programme. As long as patients are given a good justification for performing the exercises, most will follow the advice that is given. Most will understand the idea of scar tissue that needs to be 'stretched' to recover full movement that stretching the scar hurts, and on releasing the stretch the pain will abate. Reassure patients that when their pain is consistently reproduced they are affecting the necessary tissues - 'if it doesn't hurt it isn't right'. Before giving patients the following gUidelines, it is essential that they understand the reason they are performing the exercises.

Clinical Manifestations and Pathology

In the leonine facies of lepromatous leprosy, the other polar type, the reaction on the skin surface is dramatic and severely disfiguring, because the intermediate healing of involved skin produces thick, corrugated scar tissue. The lesions are often teeming with infective bacilli. The two clinical forms are not caused by morphologically distinguishable forms of M. leprae. Thus either a strong or a weak immunologic response (if this difference is the cause of the two forms of disease) produces crippling and disfigurement.

Endo Risks and Symptoms Could This Be

Endometriosis can be a stubborn and frustrating condition because of the complex interplay of hormones and unknown scarring and adhesions. Dr. Joel Hargrove, of Vanderbilt, Tennessee, has spent many years studying the effects of endometriosis. He states that PMS is reported by 80-90 percent of women with endometriosis. Conventional medical treatment is controversial and must be individualized. Medications are often prescribed to suppress ovarian function. Oral contraceptives may also be used in an attempt to prevent the proliferation of endometriosis. Side effects of suppressive medications, such as danazol, are often unpleasant and include weight gain, fluid retention, fatigue, decreased breast size, acne, hot flashes, and muscle cramps.

Timing of Reconstruction

It is essential to reconstruct the segmental mandibular defect immediately because if the resected ends of the mandible are allowed to scar and fibrose, one can never restore the native mandible to its proper position. Postoperative radiation therapy compounds the problem with contracture, and creates a functional trismus that can never be corrected. The refinement of microsurgical techniques has allowed the reconstructive surgeon to immediately and reliably transfer well-vascularized bone and soft tissue in a single operation. Immediate replacement of the tissue that is lost contributes significantly to primary wound healing. This decreases hospital stay and also helps the patient's psychological status by restoring their sense of well-being and body image. The ability to initiate radiotherapy chemotherapy early after surgery is a further benefit of primary reconstruction. Thus immediate reconstruction generally provides the optimal esthetic and functional result and is indicated for...

Determining Activation Time

The voltages recorded from the electrodes represent the sum of all potentials that are present throughout the heart at each instant of the cardiac cycle. They represent both locally generated potentials (e.g., from those cells in direct contact with the electrode) and the potentials from cells throughout the rest of the myocardium. This potential field is continuous in nature, meaning that there are no abrupt changes within the heart or on its surface. This is true even for the tissues and cells that are not excitable (e.g., blood and its constituent cells, blood vessels, connective tissue, scar tissue, and so forth), since they all have resistive properties that allow for the spread of the potential filed. Hence voltages measured from these unexcitable tissues will only reflect those potentials from distant depolarizing cells. Regardless of the algorithm used to determine a unique depolarization time, electrodes over these unexcitable cells will not have an activation time.

Soft Tissue Reconstruction

Many patients that undergo mandible resection for cancer have significant soft-tissue involvement of the floor of mouth and the tongue by tumor. Resection of the intraoral mucosal lining can lead to scarring and immobility of the remaining portion of tongue, which can create significant functional problems. Recreation of an adequate buccal sulcus

Implantable Cardioverter Defibrillator

Implantable cardioverter defibrillator (ICD) therapy is increasingly a top-choice intervention for life-threatening arrhythmias in pediatric patients. Children undergoing ICD treatment face the challenge of adjusting to a device that emits both appropriate and inappropriate shocks, the latter of which occur at a higher frequency in children than adults (Costa et al. 2007). In addition, these children encounter obstacles familiar to any child who copes with a chronic physical illness, such as school absences, physical limitations, and body scars (DeMaso et al. 2009). The literature is sparse, however, regarding the psychological impact of ICDs on children and adolescents (Blom 2008 DeMaso et al. 2004).

Vestibular dentureinduced hyperplasia

In the established denture wearer, the roll of tissue is usually composed of very mature connective tissue, which, even if the flange is trimmed back, will not shrink appreciably and resolve. However, trimming of the flange should always be carried out at the time of presentation, with or without the use of a tissue-conditioning lining to maximise the retention of the prosthesis. Surgical trimming of the excess tissue is almost always needed and this is usually done under local anaesthesia. The surgeon can manipulate the roll of tissue better by passing a suture through the lesion, allowing accurate incision along its margins. When the incision on the outer and inner aspects of the role of tissue is completed, its base can often be simply lifted and separated using a scalpel. It is undesirable to cut down to deeper tissues, as this can cause excessive scarring on healing thus reducing sulcus depth. When the base of the wound extends into lip or cheek, superficial 'tack' sutures can be...

Regression Require Commensurate Vascular Remodeling

Intermittent treatment of ob ob mice with TNP-470. Body weights of obese mice were cycled with intermittent administration of TNP-470, demonstrating vascular regulation of adipose tissue growth. (A) Obese mice were treated with vehicle or TNP-470 (10 mg kg d) (n 15) until they reduced to the weight of age-matched C57BL 6 mice. Treatment was then discontinued and the mice were permitted to regain to approximately their starting weights. The drug was then restarted and the cycle was repeated three times. (B) Photograph of representative mice from each group on day 173 (bottom of cycle 4). Except for superficial scarring, TNP-470 treatment was well tolerated. The marked remodeling capacity of adipose tissue is notable. (Reprinted, with permission, from Rupnick et al. 2002 copyright National Academy of Sciences .) Figure 2.

Preferences by Procedure

Patients with prior peritonitis, or abdominal surgery with postoperative complications that would be expected to worsen abdominal scarring, are the only subgroups in which we distinctly avoid a transperitoneal laparoscopic approach. Interestingly, patients with smaller abdomens, or prior abdominoplasty procedures, tend to be more challenging for hand assistance, because there is less room to work once the surgeon's hand is in the abdomen.

Morphology and Nomenclature of the Interproximal Papillae

Because of the absence of the periodontal ligament. This makes the interimplant papillae more like scar tissue, which may complicate any attempts for surgical repair or reconstruction. When the interimplant papilla is missing or does not totally fill the embrasure space, the condition looks like and is called a black triangle. This triangle becomes an esthetic defect that disturbs the overall treatment outcome, especially in high smile line patients, as shown in Figure 8.13. Peri-implant papillae are more clinically achievable than the interimplant papillae because the topography of the CEJ at the proximal surface of the adjacent natural tooth follows a reverse scalloping toward the incisal edge. Sharpey's fibers keep the inter-proximal bone at the same height (Misch 1999), but this is not the case for adjacent multiple implants. In cases single-tooth implants and when the distance from the contact point to the osseous crest is optimized, the results become highly predictable. (See...

Maxillary Defects and Obturators

A split-thickness skin graft should be used to line the cheek surface of the defect. This skin graft provides a keratinized surface to support the prosthesis and forms a scar contracture at the junction of the skin graft and buccal cheek mucosa, forming an undercut with which the lateral wall of the obturator can engage for increasing stability and support.

Procedures for Papilla Reconstruction

Reconstructing the interimplant papilla is one of the most technique-sensitive procedures in dental implan-tology. It requires greater surgical skills and optimal scientific background. The nature of the interimplant papilla (scar tissues) also might compromise an optimal

How To Reduce Acne Scarring

Acne is a name that is famous in its own right, but for all of the wrong reasons. Most teenagers know, and dread, the very word, as it so prevalently wrecks havoc on their faces throughout their adolescent years.
