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...

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.

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...

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...

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.

Emergency Department Treatment and Disposition

Hidradenitis suppurativa should be identified and a systemic infection ruled out. Topical and systemic antibiotics help improve lesions, especially if a secondary infection is suspected. Oral doxycycline or minocycline should be tried first with topical clindamycin. In addition, antibacterial soap is helpful to prevent secondary colonization. Incision and drainage should not be performed as this can induce chronic sinus tract formation and scarring. Referral to a dermatologist for long-term management is indicated.

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).

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

Children and Adolescents

With advanced renal disease, patients may undergo dramatic changes in physical appearance, as a result of either the disease process itself or adverse effects of treatment. Short stature and delayed puberty are common, along with long-term psychological effects that accompany these deficits (Grooten-huis et al. 2006 Rosenkranz et al. 2005). Bone deformity may be a result of ESRD. Scarring from catheter and port placements for dialysis, as well as gastrostomy tubes, may be a source of embarrassment and impaired body image. Corticosteroids and immunosuppressants commonly cause cosmetic

Removal of supernumerary teeth

If there is an associated buried incisor, a decision should be made on whether surgical exposure is indicated. It may well be opportune to avoid a further anaesthetic but many orthodontists prefer to wait for eruption, as the gingival contour may be uneven following surgical exposure. Healing after removal of a large supernumerary often produces a barrier of scar tissue, however, and patients may require surgery if the incisor fails to erupt.

What are the side effects of MUSE

The most common side effect, occurring in one-third to one-half of all men who take MUSE, is pain. This pain may be present in the penis, urethra, testis, or perineum. The intensity of the pain varies according to the dose taken. Thus, as the dose increases, the intensity of the pain may likewise increase. Hypotension and syncopal episodes (temporary loss of consciousness caused by decreased blood flow to the brain) have been reported in 1.2 to 4 of men who took MUSE, with their frequency depending on the dose used. Other side effects include urethral bleeding (in 4 to 5 of men who took MUSE), dizziness (in 1 ), and urinary tract infection (in 0.2 ). Prolonged erections and penile fibrosis (scarring) rarely occur. Ten percent of female partners experience vaginal irritation or vaginitis.

Historical Considerations

Matz and Gillies subsequently improved Bogoras's technique by creating a phallus which incorporated a urethra using the tube within a tube concept. These procedures were multistaged, resulted in extensive scarring and disfigurement of the donor area, and produced a phallus with no sensation.3,4 These types of phalloplasty are currently used for salvage cases only. Further advances involved the use of infraumbilical skin and groin flaps.5-10 However, the main limitation of these techniques were the formation of a nonsensate and wedge-shaped phallus. Musculocutaneous thigh flaps, used when there is extensive abdominal scarring from previous surgery or radiotherapy, also have been abandoned due to poor results.11 16

Tissue Engineering in Maxillofacial Surgery

Bone is a dynamic, highly vascularized tissue with a unique capacity to heal and remodel without leaving a scar (Sommerfeldt and Rubin 2001). These properties, together with its capacity to rapidly mobilize mineral stores on metabolic demand, make bone the ultimate smart material. Its main role is to provide structural support for the body. Furthermore, the skeleton also

Potential Indications

The selection of an individual candidate for PMC must be based on both clinical and anatomic variables, bearing in mind that anatomy is a simple, practical way to select patients for PMC even though it is not the sole criterion. No problem of indication is presented in cases in which surgery is contraindi-cated or with ideal candidates, such as young adults with good anatomy pliable valves and only moderate subvalvular disease (echocardiography score

Exposure of buccal canines

Overlying mucosa in the sulcus may be excised and a pack inserted, but often the tissues close over or the tooth is tethered by unsightly scar tissue. A better option is to take a normal flap and attach a gold chain as described above or simply to close the flap over the surgically exposed crown.

Endovascular Cardiovascular Valve Repair System CVRS

Is aligned with the long axis of the heart. The arms of the clip are then rotated until they are perpendicular to the line of coaptation of the valve leaflets. The open clip is advanced into the left ventricle, and retracted during systole to grasp the middle scallops of the anterior and posterior valve leaflets in the gripper arms. The positioning is confirmed by echo and the clip is locked into position. If needed, the clip is reopened, detaching from the leaflets, withdrawn into the left atrium, and the process is repeated until a functional double orifice is created. When the positioning is considered adequate, the clip is released from the guide and remains attached to the mitral valve leaflets. Eventually, fibrosis and scarring occur in the bridging segment, similar to that seen with the surgical edge-to-edge repair.55

Other Annuloplasty Devices

The application of radio frequency (RF) to remodel the mitral annulus is under development by QuantumCor (Lake Forest, CA). The concept is termed transventricular annulus remodeling, and relies on scarring and shrinkage of the mitral annulus after application of RF energy directly to the annulus. The device is intended both for surgical and transcatheter use (transseptal) and has a malleable tip with eight electrodes to deliver RF energy. The catheter is connected to a pulse generator that is modulated by temperature sensors in the electrodes to regulate the amount and time of energy delivered. The catheter can be manipulated to deliver energy to specific locations on the annulus, allowing for adjustment of the procedure to individual anatomy. This device is currently under study in an animal model.

Cervicofacial actinomycosis

Where pus is formed, incision and drainage should be carried out. Antibiotics should be prescribed for 6 weeks because they take a considerable time to penetrate the granulomatous fibrous tissue reaction in the soft tissues. Shorter courses may result in a recurrence of the infection and it is therefore important to stress to the patient the importance of continuing the antibiotic for the full prescribed period. Actinomyces israelii is sensitive to most commonly used antibiotics and, being a narrowspectrum antibiotic, penicillin is a sensible choice. If cervicofacial actinomycosis presents late or is treated inadequately, it can gravitate from the neck into the mediastinum, and this is clearly a serious complication. Less serious but disfiguring is the scarring that results from the fibrotic reaction in the neck.

Alternative recording methods for electrical signals

Surface (electrocorticographic activity (EcoG)), or from within the brain (local field potentials (LFPs)) or neuronal action potentials (spikes). These three alternatives are shown in Fig. 33.2. Each recording method has advantages and disadvantages. EEG recording is easy and non-invasive, but EEG has limited topographical resolution and frequency range and may be contaminated by artifacts such as elec-tromyographic (EMG) activity from cranial muscles or electrooculographic (EOG) activity. ECoG has better topographical resolution and frequency range, but requires implantation of electrode arrays on the cortical surface, which has as yet been done only for short periods (e.g., a few days or weeks) in humans. Intracortical recording (or recording within other brain structures) provides the highest resolution signals, but requires insertion of multiple electrode arrays within brain tissue and faces as yet unresolved problems in minimizing tissue damage and scarring and ensuring long-term...

Relating the physical and chemical characteristics of nanomaterials to their toxicity

Nanomaterial shape has already been mentioned briefly, with nanomaterials found to have many different morphologies. Fibre shape, also known as high aspect ratio, appears to play an important role in determining the toxic potential of respirable particles. Asbestos fibres (which are not nanomaterials) are related to lung fibrosis (scar tissue formation) and cancer, in particular a rather aggressive form of cancer known as mesothelioma. Mesothelioma occurs in the pleural space between the outer lung surface and the inner wall of the rib cage. The tumour is slow growing, sometimes taking 40 years to generate discernable symptoms, by which time it is so far progressed that treatment is not possible and life expectancy is often under one year. Asbestos-related diseases currently kill more than 2000 people per year due to the widespread historical use of this material. The death rate is anticipated to increase further over the next decade, and there is currently no known cure for such...

Prevalence Of Psychological Changes In Neurological Patients

Anxious, and psychotic after their brain injury Is it a simple consequence of well-understood cognitive deficits sustained in the accident For example, are they depressed because they are now amnesic or aphasic Could it even be a consequence of peripheral (i.e., nonbrain) injuries to the body, as anyone might become depressed following a brachial plexus lesion or facial scarring after a motor vehicle accident When one systematically investigates the effects of focal brain lesions, it becomes clear that specific sorts of psychological change reliably follow from particular lesion sites. For those working in cognitive neuropsychology (and cognitive neuropsychiatry) it is of no consequence whether the lesion is caused by stroke, head injury, or tumour providing it disrupts the brain region or psychological function of interest. Matters of epidemiology are also of no great concern, with scientists showing a clear preference for striking, or exceptionally pure, cases. As a result, the...

Magnetic Resonance Imaging

Through delayed hyperenhancement techniques, cardiac MRI has demonstrated that asymptomatic patients with HCM frequently have patchy foci of myocardial scarring at the junction of the interven-tricular septum and the right ventricular free wall. Furthermore, scarring was limited to the areas of abnormal hypertrophy, and the degree of scarring was proportional to the magnitude of hypertrophy, whereas wall thickening was inversely related.39 In addition, a greater extent of hyperenhancement was positively associated with high risk for SCD and with progressive disease.63 Cardiac MRI also allows for better characterization of papillary muscle insertion and orientation. It is not uncommon to see hyper-trophic, displaced, or distorted papillary muscles contributing to the obstruction and or mitral valve

How do I use the penile prosthesis and how is it placed

A penoscrotal incision is used for placement of multipart prostheses, for reoperations, and in cases of penile fibrosis (scarring). This kind of incision is made in the midline of the upper part of the scrotum. If you look at your scrotum, you will see that a line runs up the middle of the scrotum the incision is made in this line so that when it heals, it will be incorporated in the normal scrotal line.

Therapyrelated changes

Surgical scarring varies from a subtle isodense line at the site of earlier operation to a large, irregular, dense, spiculated area with marked surrounding distortion and skin change. In the latter case, detection of recurrent disease is more difficult and comparison with previous films is very helpful. For this reason, early follow-up films after wide local excision are often performed. Mammogram appearance consistent with radial scar Mammogram appearance consistent with radial scar Left image shows surgical scar and radiotherapy changes in the right breast. Right image shows normal left breast for comparison Left image shows surgical scar and radiotherapy changes in the right breast. Right image shows normal left breast for comparison

Novel Catheterbased Intervention Techniques In The Pericardial Space

Epicardial scar-related reentry has been recognized as an important cause of ventricular tachycardia, especially in patients with nonischemic cardiomyopathy. Other infrequent but clinically significant arrhythmias, such as supraventricular tachycardias and idio-pathic ventricular tachycardia, were also found to possess epicardial foci that cannot be ablated but from the epicardium. Epicardial catheter mapping and ablation in the electrophysiology laboratory have thus opened a new perspective in cardiac elec-trophysiology, which was previously limited largely to the operating room. On the other hand, the peri-cardial space is recognized as a natural drug receptacle that can restrict drug delivery to the heart, with many investigators attempting to exploit it as a reservoir to deliver therapeutic substances to the heart and coronary arteries.48 In addition, there has been increasing need to replace the standard pericardio-centesis with a safer technique, particularly in patients with...

Peroneal Tendon Injuries

Swelling and tenderness on palpation along the course of the tendon(s) is present, especially behind the lateral malleolus. Provocative maneuvers include resisted ankle eversion and dorsiflexion as well as passive ankle inversion. Patients with tendon rupture often have ankle eversion weakness. MRI may be a useful diagnostic adjunct, especially if a tendon rupture is suspected based on the mechanism of injury, severity of symptoms, and physical exam findings. Evidence of tendinopathy (fluid edema, scarring) or degenerative traumatic tendon tears will show up on MRI.

Myocardial Cellular Delivery

Autologous cells derived from striated muscle biopsy taken from the patient's limb. Isolated satellite immature cells (i.e., myoblasts) are cultured ex vivo for 1 month, then implanted directly into cardiac scar tissue in order to improve cardiac function.93 The third patient population is those with prior myocardial infarction and myocardial territory lacking viability. The aim among these patients is to regenerate the scarred area in order to improve regional and global left ventricular function.104-106 The cells being studied are predominantly autologous myoblastic cells obtained from the quadriceps muscle and expanded ex vivo for 1 month. Intramyo-cardial injection was performed either as a standalone intervention or as an adjunct to CABG surgery. The clinical results obtained so far are contradic-tory.104-106 In addition, there are a few cases of malignant ventricular arrhythmias reported soon after transplantation, indicating that the procedure may not be without significant...

Approaches To Cell Therapy

In its simplest form, differentiated cell transplantation (Fig. 58-1A), the goal is to transplant autologous cells that are differentiated or committed to differentiate into specific cells into areas of myocardial scar, with the goal being to replace areas of scar tissue with living, viable cells. In perhaps its most futuristic form, stem cell mobilization (see Fig. 58-1B), cell therapy involves the pharmacologic mobilization of a patient's own bone marrow cells into the bloodstream, homing of these stem cells to engraft into areas of myocardial damage, and then differentiation of the engrafted stem cells into cardiac myocytes and vascular structures that fully integrate with the native myocardium. An in-between strategy, stem cell transplantation (see Fig. 58-1C) involves the removal of stem cells from the bone marrow of the patient, followed by injection of the whole bone marrow or a selected population of bone marrow-derived stem cells into the infarct zone.

Management General Treatment

Patients with altered consciousness and acute hydrocephalus require emergency neurosurgical consultation. Ventricular drainage by placement of catheters into one or both lateral ventricles is indicated as an emergency procedure, often done at the bedside in an intensive care unit, in most cases. The goal is to drain cerebrospinal fluid to relieve acute hydrocephalus, reduce intracranial pressure, and restore neurologic function. The risks are insignificant in this situation and include intra-cerebral or intraventricular hemorrhage, aggravation of brain shift and neurologic injury from draining one lateral ventricle, and not the contralateral one, and inadvertent puncture of the cyst and spillage of inflammatory contents into the ventricles, causing aseptic meningitis and scarring of the ventricular system and permanent hydrocephalus and infection. External ventricular drainage is a temporizing measure to stabilize the patient until a definitive procedure can be carried out. Cranial CT...

Pathophysiology Of Myocardial Ischemiainfarction

The infarcted area, particularly when large, can undergo excessive thinning before formation of a firm scar. This process, when it occurs without additional myocardial necrosis, is termed infarct expansion. Pathologically this involves myocyte and tissue loss with disruption of normal myocardial cells in the infarct zone.

What do you do now

The decision is relatively easy in patients who present with a first seizure, and mostly relies on the use of antiepileptic medications for seizure control. In patients with CMs and chronic intractable seizures, management should be guided by the benefit risk ratio of further anticonvulsant therapy vs. the benefit risk ratio of surgical excision. The current indications for treatment of CM are recurrent bleeding, progressive neurological deficit, or intractable epilepsy. Treatment options include surgical resection or stereotactic radiosurgery. The location of the lesion in the vicinity of an eloquent cortical region such as the language areas of the brain and its association with another venous anomaly are associated with increased surgical risks including residual neurological injury and venous infarction. It is also important to consider that 1) resection of the CM does not necessarily relieve the patients of their seizures for a variety of reasons, including postoperative scar...

Resection of OLF of the Thoracic Spine Using an Image Guidance System

When thoracic myelopathy due to OLF occurs, conservative treatment is not effective, and surgery is often indicated. Because OLF is situated in the posterior part of the thoracic spinal canal, a posterior procedure with laminectomy has been employed 16-18 . Although controversial, it has been reported that laminectomy sometimes causes complications owing to scar formation in the epidural space and increased kyphotic deformity of the spine, especially in the thoracolumbar junction 17 . To prevent these complications, some

Percutaneous Fully Transvenous ICD

One new company has engineered an ICD that leverages familiar percutaneous interven-tional techniques for a time-efficient implant of this catheter-like device. The ICD is a series of thin titanium cylinders, each containing either batteries, capacitors, or circuitry, all connected by flexible couplers allowing low-impact maneuvering of anatomical angles. Positioned within the vena cava and anchored distally, the ICD also utilizes a fully integrated RV ICD lead. Early testing indicates efficient defibrillation and reliable sensing through both conventional and novel vectors. Advantages of this device in addition to the implant simplicity include that it is invisible to the patient, leaves no scar, has safety pacing and ATP capabilities, simplified follow-up capabilities tuned to the needs of the primary prevention patient, and, due to the modular design, can be readily iterated to a broader cardiac rhythm management platform.

Pathophysiology Of Diastolic Dysfunction

Several factors can affect the compliance of the left ventricle, thereby affecting the filling characteristics as well as its diastolic filling pressures. These include the completeness of ventricular relaxation, the chamber size, the thickness of the wall, the composition ofthe wall (inflammation, infiltrate, ischemia or infarction, scars, etc.), the pericardium, and the right ventricular volume and pressure.

Local therapies of nail psoriasis only rarely induce complete remission of the disease

Pustular psoriasis of the nail unit usually fails to respond to conventional topical treatments. Local treatment with topical anti-metabolites (mechlorethamine, 1 fluorouracil) is an option, even though results are variable. Systemic steroids, PUVA and cyclosporin can arrest the development of pustular lesions and avoid permanent scarring of the nail apparatus. A study of 46 patients with pustular psoriasis of the nails indicates that systemic retinoids at low dosage (less than 0.5 mg of acitretin per day) are the treatment of choice in patients with multiple nail involvement, whereas topical calcipotriol is the best option for pustular psoriasis limited to one or two nails. Topical calcipotriol is also useful as maintenance therapy in patients who responded to retinoids, in order to prevent recurrence.

Locoregional Recurrence After Primary Radiation Therapy

Additional radiation therapy can sometimes be considered for this group of patients who are not surgical candidates. However, it is important that any potential patient be chosen carefully and judiciously. Carte blanche use of re-irradiation is associated with a high major complication risk (eg, necrosis) and poor therapeutic results. The recurrent malignant cells very likely would be in a rather hypoxic environment due to the effects of the initial radiation therapy (such as scarring) and this could decrease the efficacy of treatment. These patients would need to be evaluated with respect to the following criteria (1) general condition of the patient, (2) time interval since completion of initial radiation therapy, (3) radiation dosage initially administered to the tumor and adjacent vital organs, (4) tolerance of radiation therapy and development of any complications, (5) anatomic location, extent of recurrence and adjacent vital organs, (6) condition of previously irradiated...

Myocardial Infarct Repair

The heart has very little intrinsic regenerative capacity. Numerous studies have shown that surviving cardiomy-ocytes do not re-enter the cell cycle to any significant extent (for review, see Soonpaa and Field 1998), although there are isolated reports in the literature of relatively high proliferation rates (Beltrami et al. 2001). Additionally, unlike skeletal muscle, it is not at all clear whether there is a myogenic stem cell population in the heart. As a result, infarcted myocardium is removed by phagocytes and replaced by a fibroblast-rich, provisional wound repair tissue termed granulation tissue. Granulation tissue remodels over time to form a relatively hypocellular, collagen-rich scar. Although the scar tissue has high tensile strength and serves to bridge the muscle defect in the heart, it does not contract. As a result, many patients suffer from heart failure after a myocardial infarct. 2000). The infarcted wall thins dramatically, with the final scar often being only 25...

Cardiomyocyte Grafting

Since myocardial infarction results in cardiomyocyte deficiency, a reasonable hypothesis is that replacing car-diomyocytes through cellular grafting would form new myocardium and improve left ventricular function. Initial studies with cardiomyocyte grafting showed that fetal or neonatal cardiomyocytes could form new myocardium when implanted into the normal hearts of mice (Soonpaa et al. 1994 Koh et al. 1995), rats (Leor et al. 1996 Con-nold et al. 1997 Reinecke et al. 1999 Scorsin et al. 2000 Muller-Ehmsen et al. 2002), and dogs (Koh et al. 1995). In contrast, adult cardiomyocytes did not form viable grafts (Reinecke et al. 1999). Furthermore, Soonpaa et al. (1994) showed that the transplanted cardiomyocytes formed intercalated disks (specialized junctions for electromechanical coupling) with host cardiomyocytes, suggesting they would beat synchronously with the host. Subsequent studies showed that fetal or neonatal car-diomyocyte transplantation could form new myocardium in injured...

Authors Preferred Method

After adequate tendon debridement and bony resection, all bone edges are smoothed and feathered and bone fragments lavaged. The split Achilles fibers are reapproximated loosely with simple interrupted buried absorbable suture. The paratenon is reapproximated with a running absorbable stitch. We feel that closure of the paratenon is critical to prevent scar adherence of the skin to the Achilles tendon. The skin is closed with nonabsorbable monofilament vertical mattress stitch after a suction drain is placed (Fig. 19.9). The patient is placed in a non-weight bearing, bulky Robert-Jones dressing with the ankle in 10 degrees of plantarflexion.

Micro and Nanoscale Smart Polymer Technologies

Smart polymers are macromolecules capable of undergoing rapid, reversible phase transitions from a hydrophilic to a hydrophobic phase and are thermodynamic systems that undergo a phase transition for a certain range of parameters such as pressure, temperature, and pH.8,15-18,20 Furthermore, there are protein-based polymers that will adhere to surrounding tissue or behave as a barrier to scar tissue, as well as polymers that are electroactive in nature whose properties change drastically upon change of stimulus. Additionally, polymers that respond differently to changing mechanical properties such as strain rates have numerous potential uses in the musculoskeletal system in terms of replacement devices or shock absorbers in the human joints. Aging often results in degenerative joints that have less efficient shock-absorbing behavior, which is further amplified in the spine, where each intervertebral disc serves as a shock absorber to spinal motion....

Guided bone regeneration

Healing by osteoblasts produces bone but, when a blood clot is organised by fibroblasts, collagen formation is predominant and scar tissue is formed. When a suitable membrane is placed over bone, however, fibroblasts are excluded and angiogenesis and osteogenesis occur in the cavity below. This is the basis of guided bone regeneration.

Clinical Manifestations and Pathology

1 or 2 days of fever, chills, malaise, and gastrointestinal symptoms before symptoms of local disease appear. Either with or without prodromal symptoms the patient becomes aware of some pain, at times with itching, in the area of the affected segmental nerves. After several days, crops of vesicles on an erythematous base appear in the distribution of the nerves of one or several posterior root ganglia, usually accompanied by hyperesthesia and pain. The vesicles dry and become crusted in about a week, although the course may be slower in aged persons. Hyperesthesia or pain may last for weeks and months especially in those patients with malignant disease. In an occasional aged patient, these residua never disappear. Herpes of the ophthalmic branch of the trigeminal nerve is not uncommon and may be accompanied by keratoconjunctivitis, which may be followed by serious corneal scarring and glaucoma. Zoster of the geniculate ganglion produces Ramsey Hunt's syndrome. The characteristic pain...

Models of Human Development

Although this example takes a stage-like view of human development, another tradition looks to the work of Vygotsky and his followers, seeing development more as a process of internalization from social situations that scaffold for the thinking of the participant (1978). In addition to its Pi-agetian emphasis, the work of Adey and Shayer draws upon social scaffolding. Scar-damalia and colleagues developed an initiative initially called CSILE (Computer Supported Intentional Learning Environments) and now Knowledge Forum, that engages students in the collaborative construction of knowledge through an online environment that permits building complex knowledge structures and labels for many important epistemic elements such as hypotheses and evidence (Scardamalia, et al., 1989). The social character of the enterprise and the forms of discourse it externalizes through the online environment create conditions for Vygotskian internalization of patterns of thinking. Studies of impact have...

Clinical Manifestations and Pathology Trachoma

Stage 3 (cicatrizing trachoma) is the scarring and healing stage. The follicles rupture, and scar tissue forms on the undersurface of the upper lids. Scar tissue also appears elsewhere on the conjunctiva. At first, the scars are pink but later turn white. It is not uncommon for a new infection of C. trachomatis to occur at this stage and to start the process all over again. Thus Stages 2 and 3 may coexist for many years and may be further complicated by repeated bacterial infections. With each new attack, more scar tissue appears, and an ever-increasing pannus covers the cornea. This phase may be several years in duration. Stage 4 (healed trachoma) is the final stage of the disease in which healing has been completed without any signs of inflammation, and the disease is no longer infectious. Trachomatous scarring remains, however, and may deform the upper lid and cause opaqueness in the cornea. The thickening of the upper lids gives a hooded appearance to the eyes. Because scarring of...

Diseases Of Connective Tissue And Joints

Usually Ehlers-Danlos syndrome is characterized by excessive mobility ofjoints and a thin stretchable skin. However, in type 4 Ehlers-Danlos syndrome these findings are attenuated and patients have bruises and pigmented scars over the bony prominences. Patients with type 4 Ehlers-Danlos syndrome may have an aortic aneurysm and rupture as well as mitral valve prolapse (103a).

Approach to the Reoperative Patient

In a classic study by Purnell and associates15 of a large number of patients with asymptomatic HPT being followed without operation, it was clearly demonstrated that 20 developed compelling indications for operation within 5 years. Parathyroidectomy for asymptomatic HPT results in normalization of biochemical values and bone density, and approximately one quarter of those who did not undergo operation did have some progression for periods of up to 10 years.16 Cervical exploration seems justified in all patients with documented primary HPT since normocalcemia is restored in more than 95 of patients, mortality is nearly nil, and morbidity is rare when the operation is performed by an experienced endocrine surgeon.1 However, in contrast with patients with primary HPT, this liberal indication should be reconsidered cautiously in patients with recurrent or persistent primary HPT. In the reoperative situation, the obliteration of tissue planes by scar tissue leads to a greater risk of...

Clinicopathologic Correlations


Both types of ulcers usually heal within 2 to 3 weeks without scarring. A solitary, or giant, aphthous ulcer of the palate is shown in Figure 12-45. The patient has periadenitis mucosa necrotica recurrens, also known as major aphthous ulcer. These lesions are larger than multiple aphthous ulcers and start as submucosal lesions that break down to form ulcers that may persist for many weeks before healing by secondary intention. Any part of the oropharynx may be affected, but the tonsils and soft palate are the most common sites.

What other disorders can mimic BPH

A urinary tract infection can cause urinary frequency and burning with urination. A urethral stricture or scar tissue in the urethra from old infections or trauma can cause a decrease in the urinary stream.

Physical Examination

Vaginal Palpation

Inflammatory lesions, ulceration, discharge, scarring, warts, trauma, swelling, atrophic changes, and masses are noted. Figures 19-14 and 19-15 show condylomata acuminata of the labia. The perineum and anus are inspected for masses, scars, fissures, and fistulas. Is the perineal skin reddened The anus should be inspected for hemorrhoids, irritation, and fissures.

Hereditary C2 Deficiency

The rash in atypical cutaneous lupus erythematosus patients bears striking resemblance to the rash in the antinuclear antibody (ANA)-negative group and to that in SCLE. The skin lesions have been described as non-scarring, papillosquamous, or annular polycyclic, with a characteristic distribution (i.e., the lesions spare the knuckles, inner aspects of the arm, axilla, lateral part of the trunk, and are rarely seen below the waist). Because the skin lesions differ from those in discoid lupus erythematosus in their clinical appearance and

Olecranon Fracture Screw Fixation

A postoperative posterior splint at 90 degrees of elbow flexion and neutral rotation is removed within 2 weeks. Progressive range-of-motion exercises are followed by progressive resistance exercises once full range of motion is achieved. Residual or recurrent pain is treated with decreased activities, anti-inflammatory drugs, scar massage, ultrasound therapy, and cryotherapy. Surgical intervention is reserved for refractory cases with symptoms persisting longer than 6 months to 1 year despite persistent conservative management. Precise localization of the maximal point of tenderness preoperatively is important (Fig. 35-6). The origin of the pronator teres and flexor carpi radialis are exposed. Torn, scarred, and abnormal tissue is excised. Normal tissue is left intact to avoid iatrogenic injury to the ulnar collateral ligament. Care must be taken to protect the medial Figure 35-8 The thickened, scarred olecranon bursa is excised through an incision centered lateral to the midline....

Bleeding From The Lower Genital Tract

Major Blood Loss

As always, initial management consists of resuscitation measures and analgesia followed by a period of observation. For hematomas that are less than 5 cm and not expanding, conservative treatment with ice packs, pressure dressing and analgesia is recommended22. The visible skin margin of the hematomas should be marked to help establish whether it is expanding. For hematomas that are expanding or more than 5 cm in size, surgical intervention is recommended. Where possible, the surgical incision should be made via the vagina to minimize visible scarring. Distinct bleeding points should be under-run with figure-of-eight dissolvable sutures. The presence of any residual bleeding or a hematoma cavity is an indication for insertion of a drain, a vaginal pack and a Foley catheter, all of which should be left in place for at least 24 h. Usually, however, no distinct bleeding point can be seen, in which case a drain and pack should be inserted10.

Papillary Thyroid Carcinoma Rationale for Total Thyroidectomy

I also recommend completion total thyroidectomy, except for patients who have occult papillary or minimally invasive follicular thyroid cancers. When the initial thyroid operation was a total lobectomy, this completion thyroidectomy should not be associated with any higher risk of complications, as my colleagues and I58 and others59 have reported. The best time to perform a total thyroidectomy is also at the initial operation, when it can be done safely and there is less scarring.

Nowhere is the link between mind and body more evident than in the experience of abuse. This connection gives us a unique opportunity to employ body-centered methods to heal emotional scars. While talk-based and cognitive therapies can be of great benefit, there are situations in which mind-body approaches, such as yoga, qigong, tai chi, breathing practices, and meditation can be extremely beneficial and sometimes necessary for full recovery.

Splints Acting on the Thumb

Immobilization splints prevent motion of the entire thumb or of selected segments within the thumb ray to allow healing, control early postoperative motion, decrease pain, or enhance functional use. Inflammatory conditions and soft tissue injuries of thumb structures often require splint immobilization. Postoperative immobilization between exercise periods effectively limits use while allowing early motion. Mobilization splints maintain or increase passive range of motion. For supple thumb joints, in a paralyzed or partially paralyzed thumb, mobilization splinting preserves passive range of motion and prevents deformity while permitting continued functional use. Since optimal effectiveness of the thumb depends on combined mobility and stability, when thumb motion is limited by tethering scar and fibrosed soft tissues, restoration of motion of the three thumb joints is an important part of the rehabilitation process. Splinting and active range of motion exercises, combined with...

Indications and Contraindications

Ruptured Ovarian Cyst

Because of the high incidence of cyst recurrence following simple percutaneous drainage, multiple sclerosing agents have been proposed, including the use of alcohol, tetracycline, minocycline, or povodine-iodine with variable success (5,19,20). These sclerosing agents should, however, be avoided in parapelvic cysts as scarring and strictures of the collecting system have been reported (5).

Retroperitoneal lymph node dissection

Primary RPLND is associated with negligible mortality and minimal morbidity rates when performed by experienced surgeons 33,34 . In the Indiana University experience there were no perioperative deaths, no permanent disability from complications, and 2.3 of patients required reoperation 33 . The most common long-term complications of primary RPLND are a 1 to 2 incidence of small bowel obstruction, a 0.4 incidence of lymphocele or chylous ascites, and a midline abdominal surgical scar.

Specific Complications

A well-positioned collar incision, approximately 2 cm above the jugulum or 1 cm below the cricoid cartilage, extended laterally and closed by intracutaneous running suture, gives the best cosmetic result. A lower incision is more prone to keloid development. If this occurs, excision of the scar after 1 year may reduce the size of the deformity. Infections occur rarely in thyroid surgery, most often when combined with lymph node dissection (3 patients 0.4 in our series, one of whom also had a tracheostomy). Apart from normal surgical hygiene and disinfection and the avoidance of operations in patients with acute sore throats, no additional preventive measures are required. Infections should be treated by opening the wound and evacuating the pus. After adequate drainage, when granulation starts, the wound can be excised and closed secondarily by intracutaneous suture, which gives the same excellent aesthetic result as in uncomplicated primary closure. Seroma can be treated by aspiration.

Diagnosis Of Sjogrens Syndrome With Salivary Gland Biopsy

Sjogren Disease Histology

Incisional biopsy of the parotid gland has at least theoretical benefit and justification in the diagnosis of Sjogren's syndrome. Previous recommendations for major salivary gland biopsy reported potential complications of facial nerve damage, cutaneous fistula, and scarring of the facial skin when utilizing a parotid biopsy to establish or confirm a diagnosis of Sjogren's syndrome. Incisional parotid biopsy may be performed without assuming any of these complications, except in very rare circumstances (Marx, Hartman, and Rethman 1988). Recent studies, in fact, point to a higher yield of diagnosis when using the parotid biopsy (Marx 1995) (Figure 6.6). In Marx's series of 54 patients with Sjogren's syndrome, 31 (58 ) had a positive labial biopsy, while 54 (100 ) had a positive parotid biopsy (Marx 1995). He concluded his study by stating that incisional parotid biopsy will confirm and definitively document the diagnosis of Sjogren's syndrome (Figure 6.7). The incisional parotid biopsy...

Extracorporeal High Intensity Focused Ultrasound Tissue Tripsy in Prostatic Disease

The approach was first used clinically to ablate the transition zone in obstructive benign prostatic enlargement. Although both experimental and phase II clinical studies showed high-intensity focused ultrasound for benign prostatic enlargement to be safe and minimally invasive, long-term results were disappointing (51-57). In spite of treatment times in spinal anesthesia of around 60 minutes, tissue ablation with larger median lobes or calcification was frequently insufficient. Obstruction at the bladder neck was often not permanently eliminated because of the development of scar tissue, and the treatment result was poorly predictable in the individual patient.

Tissue repair process

Following tissue injury, the process that in principle leads to recovery is divided into three overlapping phases inflammation, repair and remodeling (Evans 1980 Hardy 1989 Enwemeka 1989 Barlow and Willoughby 1992). No inflammation no repair is a valid dictum (Carrico et al. 1984). In fact, each part of this process is essential to the structure of the final result. Connective tissue and muscle do not regenerate if damaged, but are replaced by inferior fibrous scar tissue (Evans 1980 Hardy 1989). To produce optimal repair tissue, all phases of this process need to be completed in the appropriate time. To encourage good quality repair with collagen fibres oriented according to stress lines, gentle natural tension should be applied to recent injuries, commencing at about the fifth day (Evans 1980). Gentle tension applied early in the healing process promotes greater tensile strength in the long-term. From the first week a progressive increase in movement should be encouraged so that...

The Challenge of Creating Cultures of Thinking

Culture has been mentioned briefly in previous sections, but one still might ask What is it about culture, and cultures of thinking in particular, that demands attention (see Greenfield, Chap. 27, for further discussions on the role of culture) Three important motives are worthy of attention First, the supporting structures of culture are needed to sustain gains and actualize intelligent behavior over time, as opposed to merely building short-term capacity (Brown & Campione, 1994 Scar-damalia et al., 1994 Tishman, Perkins, & Jay, 1 993). It is through the culture of the classroom that strategies and practices take on meaning and become connected to the work of learning. Second, culture helps to shape what we attend to, care about, and focus our energies upon (Bruner, Olver, & Greenfield, 1966 Dasen, 1977 Super, 1980). Thus, culture is integrally linked to the dispositional side of thinking and to the cultivation of inclination and sensitivity. Third, researchers and program developers...

Achieving Soft Tissue Closure in Immediate Implant Therapy

Epithelial Tissue Tooth Extraction

The free gingival graft might lead to the creation of an adequate zone of keratinized tissues on the donor tooth, avoiding the creation of mucogingival problems however, scar tissue can be noticeable a few months' posthealing. Becker and Becker (1990) have recommended using a split-thickness flap from the tooth adjacent to the donor tooth to cover the exposed bone on the donor tooth, or closing the mesial and the vertical incision the best way possible, and to correct any mucogin-gival problems at a later date, if they arise. The patient is placed on 500 mg of amoxicillin every 8 hours for 10 days, starting 24 hours before the procedure, and is Figure 6.10a View of the rotation of the buccal flap to cover the implant Figure 6.10F.

Complications of wound healing

Infection Dehiscence Incisional hernia Hypertrophic scarring Keloid scarring Contractures Hypertrophic scarring Hypertrophic scarring is essentially excess collagen scar tissue formation - almost an overhealing of a wound. It is non-progressive after 6 months and does not extend beyond the edges of the wound. It occurs most frequently in specific areas, particularly around joints and where Langer's lines of tension are crossed by the incision. Poor skin suturing technique frequently results in hypertrophic scar formation, especially where the edges of the skin are overlapping instead of being accurately apposed. Treatment is difficult and further surgery should not be attempted for at least 6 months. Excision of the scar and resuturing often has disappointing results, resulting in the same overhealing. Radiotherapy used to be used but has now been abandoned. Some improvement can be achieved with local injection of corticosteroids directly into the scar, a process that might need...

Esthetic Guidelines of Implant Exposure Surgery

Soft Tissue Manipulation Around Implants

To avoid the formation of any scar tissue on the labial gingival interface Cosmetic incisions can be beveled toward the center of the flap at a 45-degree angle, thereby minimizing the chances of postoperative soft tissue scarring. This can be achieved with the use of microscalpel blades and small-diameter suturing materials. Some second-stage surgical guidelines or recommendations are made to reduce postoperative complications and maximize the esthetic outcome around dental implants. They can be used as a guide or a reference for clinicians who desire esthetic surgical results. There is a close relation between implant positioning osseous crest and resultant perio-implant soft tissue contours.

Contraction Stress Test

Is considered positive if late decelerations accompany 50 or more of contractions. A positive CST is predictive of fetal compromise and distress in labor in up to 80 of cases and in specific clinical situations indicates need for delivery of the fetus. The presence of fewer decelerations indicates a suspicious study. The latter two conditions mandate need for further evaluation. Contraindications to a CST include risk of preterm labor, placenta previa, classic uterine scar or full thickness scar from previous uterine surgery, incompetent cervix, and multiple gestation (Babbitt, 1996).

Aims advantages and disadvantages of laminoplasty

Nuchal muscles and spinal ligaments which were totally or partially detached to expose laminae can be reat-tached to preserved posterior spinal structures, and this may prevent development of the cervical instability which often happens after laminectomy, particularly in those subjects below 50 years of age. The spared laminae preserve the protective function of the spine, shielding the spinal cord from pressure from hematoma during the early postoperative period and preventing the invasion of scar tissue subsequent to hematoma in the late convalescent period. Development of kyphosis in combination with a thick peridural scar following laminectomy is a notorious cause of late neurological deterioration in laminectomy.

Lower Uterine Segment

Important pathologies here involve implantation on a previous Cesarean section scar, with abnormal adherence or formation of a diverticulum. An important cause of weakening of a Cesarean section scar is infection. Postoperative wound infection is not uncommon following Cesarean section, particularly emergency section. Prophylactic antibiotics can modify the extent and rate of infection, as can the quality of closure, the amount of local tissue trauma, the technique used (one- or two-layer), swelling, hematoma and the nature of the organisms infecting the wound. There may be extensive disruption and inflammation in the uterine wall despite a normal healing appearance of the skin wound. Conservative treatment of the wound is normal, and surgical debridement the exception. Accordingly, the consequences may be only appreciated in a subsequent pregnancy. If the patient does present before this, hemorrhage and or vaginal discharge may prompt internal examination. A defect may be identified...

Shoulder Arthroscopic Bankart Repair

Lateral Shoulder Arthroscopy Drape

Either an open or arthroscopic approach for revision surgery can be used to address recurrent instability however, scarring and disruption of normal tissue planes can complicate an open revision. If an open approach is chosen, an initial arthroscopy can be beneficial. The posterior and superior labral attachments should be evaluated. Although the surgical approach for open revision stabilization is the same as previously described, the separation of the capsule from the subscapularis is inherently more difficult. The Bankart lesion, if present, is repaired and a capsulorrhaphy to eliminate capsular redundancy is performed.

Techniques of laminoplasty and supplementary procedures

Double Door Laminoplasty

A cervical spine with OPLL tends to be kyphotic, although the reason for this is not clear. Fortunately, few patients deteriorated due to kyphotic deformity after lamino-plasty. Formed laminae prevent infiltration of scar tissue into the spinal canal and maintain room for the spinal cord.

Bowens Disease and Erythroplasia of Queyrat

Erythroplasia Queyrat

Bowen's disease (BD) is squamous cell carcinoma (SCC) in situ most often caused by chronic solar damage. Therefore, lesions are found most often on the dorsal hands and forearms, neck, ears, bald scalp, and face. HPV also has been documented as a cause of BD, especially HPV-16. Inorganic arsenic ingestion, radiation dermatitis (x-ray damage), immunosuppression or HIV, burn scars, and chronic ulcers are also associated with BD. The overall risk of progression of BD to invasive cancer is about 3 to 5 , However, risk is greater for patients with oral and genital lesions (about 10 ), as well as those with a history of arsenic exposure or lesions located in a chronic scar or ulcer.

Aphthous Ulcers Canker Sores Clinical Summary

Aphthous ulcers are shallow painful mucosal ulcers of 1 to 15 mm. A prodromal burning sensation may be noted 2 to 48 hours before an ulcer is noted. The initial lesion is a small white papule that ulcerates and enlarges over 48 to 72 hours. Lesions are typically round or ovoid with a raised yellow border and surrounding erythema. Multiple aphthous ulcers may occur on the lips, tongue, buccal mucosa, floor of the mouth, or soft palate. Spontaneous healing occurs in 7 to 10 days without scarring. The exact etiology is unknown. Deficiencies of vitamin B12, folic acid, and iron as well as viruses have been implicated. Stress, local trauma, and immunocompromised states have all been cited as possible precipitators.

Directed Neurological Examination

The examination proceeds with an inspection of the external ear and ear canal looking for malformations, infections, masses, or asymmetry. Next, the tympanic membranes should be inspected for wax, perforation, otitis, or mass lesions. It is usually prudent to remove wax before embarking on more sophisticated diagnostic procedures. The tympanic membranes contribute about 20 db to the hearing level. Disorders such as perforation, scarring, fluid accumulation, or wax impaction can cause a conductive hearing loss. A normal tympanic membrane is translucent. Fluid behind the tympanic membrane imparts a straw color.

Cervical Spine Assessment

Examining the cervical spine requires a thorough neurological and a rthrological scan of the spine and entire upper quadrant. The temporomandibular joint, upper thoracic spine, costovertebral joints, costotransverse joints, first rib, rib cage, and shoulder complex also have a large influence on the cervical spine and should be ruled out when assessing cervical pathologic conditions. Because of the frequent occurrence of motor vehicle accidents, the athlete must always be questioned regarding a previous accident or whiplash injury. If there has been a previous whiplash to the cervical spine, there is usually scar tissue and dysfunction that will affect the testing. It is also important to determine the emotional status of the athlete in the general history because stress or increased muscle tension can make testing more difficult and may alter the results.

Pericytes and Disease

Pericyte loss or a reduced pericyte to EC ratio may be achieved through migration of pericytes from their microvascu-lar location under pathological or physiological conditions, selective pericyte death or from reduced pericyte turnover or maintenance. Pericytes migrate naturally during the early phases of physiological angiogenesis to make way for growing sprouts (113, 114), or in response to stress or injury (21). Migration following TBI is thought to promote survival as pericytes remaining in their vascular location show signs of degenerative activity (21). However, migration is also thought to play a pathogenic role in diabetic retinopathy (115). Decreased pericyte to EC ratios have been observed following TBI (21) and stroke (116), multiple sclerosis (117-121), brain tumor (122, 123), diabetic retinopathy (124), aging (125, 126), and in a variety of angiopathies (127). Pericyte loss may also play a role in Alzheimer's disease, however enhanced pericyte coverage of some vessels...

History and Geography Antiquity

Trachoma is a roughness of the inner surface of the lids. When the disease is of greater intensity it is also called fig disease. If the disease is chronic and cicatricial then it is called scar. Topical medications are indicated. They consist of wine and two kinds of red iron ore. These are washed and then the inner surface of the lid is gently cauterized. (Hirschberg 1982) The Greeks and the Arabs thus knew far more about trachoma than did their counterparts in Europe until the nineteenth century. They recognized different forms of trachoma (MacCallan's four stages in contemporary language) the follicles and papillae, which they compared to the appearance of a halved fig the scars the contagiousness (sometimes referred to as heredity, meaning in the family ) and the danger of old trachoma, or reinfection. The Arabs were also able to recognize the connection of trichiasis and pannus with trachoma, and their operative and topical treatments of tra When the ship arrived in Guadeloupe,...

Surgical Technique Biceps Tenodesis

Several techniques for tenodesis of the biceps have been described that range from all open to arthroscopically assisted to all arthroscopic. Many of these techniques require expensive implants or involve creating large drill holes in bone. Presented in this chapter is a simple all-arthroscopic percutaneous intra-articular transtendon (PITT) technique.26 This technique requires no specialized hardware and can be performed with a spinal needle, suture material, and standard arthroscopic equipment. The design of the percutaneous intra-articular transtendon technique is based on the premise of tenotomy with scarring in the bici-pital groove that occurs in cases of trauma or degeneration.

Surgical complications

Although morbidity is limited, the most frequent complication from inguinal orchiectomy is bleeding from the spermatic vessels into the scrotum or retroperitoneum. Misinterpretation of retroperitoneal hematomas as metastatic disease may result in unnecessary treatments 11 . Inappropriate scrotal violation, reported in up to 17 of cases, can alter lymphatic drainage and or contaminate the scrotum with neoplastic cells resulting in a risk of local recurrence between 2.9 and 11 12-14 . Wide excision of the scrotal scar should be performed in such cases. Additional treatment for seminoma should include extension of the radiation field to include the ipsi-lateral groin and scrotum, although systemic cyto-toxic therapies do not demonstrate a survival advantage.

Expansive Laminoplasty

Radiografia Cervical

For cervical myelopathy caused by multilevel OPLL. However, surgical results were rather unpredictable owing to the inherent traumatic nature of laminectomy, leading to various complications, including vulnerability of the unprotected spinal cord and recurrent myelopathy caused by the development of postoperative kyphosis or epidural scar formation 7 . In 1968, Kirita devised a sophisticated technique in which the laminae were thinned and divided at the midline using a high-speed drill followed by total resection of the laminae to achieve simultaneous decompression of the compromised spinal cord 8 . This procedure significantly improved the surgical results and reduced the postoperative complication rate. However, problems inherent to laminectomy, such as postoperative kyphosis, vulnerability of the spinal cord, and stenosis due to scar formation, remained unsolved 9 . To address such issues, in 1973 Hattori and his coworkers devised an expansive Z-plasty of the laminae in which the...

Posttraumatic Epilepsy

Post-traumatic seizures may be associated with the typical pathological changes that may be seen in brain injuries including reactive gliosis, axon retraction balls, wallerian degeneration, microglial scar formation, and cystic white matter lesions. y When a contusion or cortical laceration is present, the breakdown of hemoglobin releases iron. Based on animal and cell culture studies, iron may increase intracellular calcium oscillation and may increase free radical formation through activation of the arachidonic acid cascade producing increased intracellular calcium resulting in excitotoxic damage, neuronal death, and glial scarring, which lead to epileptiform activity. y These findings suggest a possible role for neuroprotective treatment in the future.

Splinting for Joint Contractures

Human Joint Contractures

Maintained at a constant level over time. Although in human flexor tendon the amount of creep is very small, a ligament was found to demonstrate considerably more elongation. He does note, however, that when a ligament of predominantly elastic fibers is subjected to a small force, the creep cannot be measured accurately. It was his impression that when the load is applied to a finger, the elongation that occurs actually reflects creep in the scar around the ligament rather than the ligament itself. The load levels that can be applied and tolerated by a finger are far below those, which cause tendon or ligament elongation, and changes that occur are probably the result of physical changes within the scar tissue. There must be particular concern for the effect of excessive stress on a joint when it is applied for too long a period or with too great a mechanical advantage. The joint quickly reaches the maximum rotation permitted by the scar tissue, and at that point the joint can be...

What happens when hormone therapy fails

Still believed to have organ-confined disease. Individuals in this group include those who have a Gleason score 6, a low pretreatment PSA level ( 10 ng mL), and low clinical stage tumor (T1c or T2a). At the time of the salvage prostatectomy, they should still have a favorable Gleason score, a low clinical stage, and, ideally, a PSA that is 4 ng mL. Salvage prostatectomy is a challenging procedure, and if you are considering this option, you should seek out an urologist who has experience with it because there is an increased risk of urinary incontinence, erectile dysfunction, and rectal injury with this procedure. Rarely, because of extensive scarring, it is necessary to remove the bladder in addition to the prostate, and a urinary diversion would be necessary. A urinary diversion is a procedure that allows urine to be diverted to a segment of bowel that can be made into a storage unit similar to a bladder or allows urine to pass out of an opening in the belly wall into a bag, similar...

Ascites In Pathophysiology In Book

Portal Vein Anatomy

Sinusoidal damage from cirrhosis is the most common cause of portal hypertension. The sinusoids are porous vessels within the liver that surround radiating rows of hepatocytes, which are the basic functional cells of the liver (Fig. 22-2). Progressive destruction of hepatocytes and an increase in fibroblasts and connective tissue surrounding the hepatocytes culminate in cirrhosis. Fibrosis and regenerative nodules of scar tissue modify the basic architecture of the liver, disrupting and reducing hepatic blood flow as well as normal liver function. Reduced hepatic blood flow alters the normal metabolic breakdown processes and decreases protein synthesis within the liver. The course of alcoholic liver disease moves through several distinct phases from development of fatty liver to the development of alcoholic hepatitis and cirrhosis. Fatty liver and alcoholic hepatitis may be reversible with cessation of alcohol intake, but cirrhosis itself is irreversible. Although the scarring of...

Chlamydia trachomatis

Donovan Bodies

The majority of women with Chlamydia infection are without symptoms. Many men are asymptomatic as well. Regular screening for Chlamydia, as recommended by the USPSTF, can significantly reduce the incidence of pelvic inflammatory disease (PID), one of the most serious sequelae of untreated infection. In women with untreated Chlamydia infection, in addition to PID, tubo-ovarian abscess, tubal scarring and ectopic pregnancy, and infertility can all result.

Tarsal Tunnel Syndrome

SYMPTOMS There is aching or sharp pain around the medial part of the foot and ankle joint, often radiating along the medial or the lateral part of the foot, or towards the plantar fascia insertion. AETIOLOGY This syndrome is caused by trapping of the posterior tibia nerve or any of its branches in the tarsal tunnel, most often after scarring from trauma. Other non-traumatic aetiology, such as varicose veins, neuroma or tumours, may also trap the nerve.

Recurrent attacks may be less painful to painless as generalized corneal anesthesia develops. Patients with AIDS or other immunosuppressive conditions are very susceptible to this recurring infection. Figure 10-56 shows a corneal ulceration secondary to HSV infection. Marked blepharospasm is common with corneal ulceration. The most common characteristic finding of HSV-related keratitis is the dendritic ulcer on the cornea. This ulcer is the result of active viral replication in the corneal epithelial cells. Figure 10-57 shows HSV-related keratitis. The eye has been stained with rose bengal. The devitalized, swollen cells laden with the replicating virus stain brightly with this substance. Figure 10-58 shows corneal scarring in another patient as a result of a previous herpes zoster infection.

Lateral Approach for Parathyroid Exploration

The lateral approach is preferable in parathyroidectomy under local anesthesia because the limited dissection and moderate retraction of the neck muscles are well tolerated by patients.68 Another indication for the lateral approach is parathyroidectomy after previous neck surgery. The lateral approach in these patients provides a dissection plane more likely to be devoid of scar tissue from the previous operation.75

Aqua therapy may be implemented using a flotation device to prevent weight bearing on the operative leg. Range-of-motion exercises are continued from week 2 in order to increase dorsiflexion to neutral using a strap or towel (Fig. 9.2).

The most common complications of PUD include UGIB, perforation, penetration, and gastric outlet obstruction. An upper GI hemorrhage can occur in up to 15 of patients with PUD and is most common in patients older than 60, with mortality as high as 10 . Perforation occurs in approximately 7 of patients with PUD, again classically in elderly patients receiving long-term nonsteroidal anti-inflammatory drugs (NSAIDs). Perforation can be confirmed on plain abdominal radiography barium contrast studies and upper endoscopy are contraindicated with suspected perforation, and urgent surgical consultation is mandatory. Mortality may be as high as 30 to 50 in patients with perforation, particularly in elderly and debilitated patients. Penetration occurs when the ulcer crater erodes through and into adjacent organs, including the small bowel, pancreas, liver, and biliary tree. Often subtle, it typically presents as acute pancreatitis. Gastric outlet obstruction occurs in 1 to 3 of PUD patients,...

Treatment Desired Outcomes and Goals

While eliminating existing lesions and preventing the development of new lesions are primary goals of acne therapy, secondary goals include relieving pain or discomfort and preventing permanent scarring.8 In addition, acne can cause patients a significant amount of stress, anxiety, frustration, embarrassment, and even depression. 0 Because of these psychological symptoms, treatment compliance and patient education on both physical and psychological aspects of this skin disorder are also imperative.

Submandibular Gland Tumors

In recurrent PA the disease will frequently be multinodular as in the parotid, and as 45 of these cases involve the subcutaneous tissue under the previous operative scar, excision of the scar with a margin of the surrounding skin is recommended as part of the en bloc excision (Laskawi et al. 1995).
