Oligodendroglial cytolysis caused by a papovavirus C generic differin 15 gr with amex. CD8+ T cell attack on neuroglial cells minimally infected with a retro- virus D. Misfolding of a protease-resistant protein causing plaques in the brain E. Mutation in the matrix protein of a virus causing viral persistence Key Concept/Objective: To be familiar with theories of pathogenesis for CNS diseases caused by slow viruses and similar agents Spongiform encephalopathies are caused by prions: proteins that, when abnormal, pre- cipitate as crystals, yielding plaques and spongiform degeneration. HIV dementia is thought to be caused by injury to neurons by toxins secreted from HIV-infected microglia. HTLV-I–associated myelopathy is thought to be the result of autoimmune attack by CD8+ T cells on HTLV-I–infected glial cells. Lysis of cells that produce myelin (oligodendrocytes) by reactivated JC virus, a papovavirus, is the cause of progressive multifocal leukoen- cephalopathy. Subacute sclerosing panencephalitis (SSPE) is a late CNS disease caused by the measles virus containing mutated protein, perhaps accounting for viral persistence in the presence of an appropriate host-humoral response. An HIV-seropositive 36-year-old woman presents with progressive right-sided weakness and right inferi- or quadrantanopia. MRI reveals hypointense T1-weighted lesions without gadolinium enhancement and with hyperintense T2-weighted lesions involving the left frontoparietal and occipital white matter. Biopsy shows areas of demyelination, large atypical astrocytes with bizarre nuclei, and oligodendrocytes with enlarged nuclei, some with displacement of the chromatin by an intranuclear basophilic process. What is the most appropriate therapy for this patient at this time?

What would be your recommendation regarding the management of this patient’s gallstones? Recommend not having surgery and continue to monitor clinically B buy cheap differin 15gr online. Recommend cholecystectomy, because he has diabetes and he is at high risk for developing complications from acute cholecystitis in the future C. Recommend surgery, because he is at high risk for developing gallblad- der cancer in the next few years D. Recommend oral ursodiol for dissolution of the stones Key Concept/Objective: To know the appropriate treatment of asymptomatic cholelithiasis Most gallstones are asymptomatic and are an incidental finding on ultrasonography per- formed for other reasons. Exceptions may be made for patients at increased risk for gall- bladder cancer. In this case, the pain was related to nephrolithiasis (hematuria, left-sided pain, left kidney stones), and the patient has been otherwise asymptomatic. Oral dissolution therapy is usually unsuccessful and requires long-term treatment. On the basis of this information, prophylactic cholecystectomy is not indicated for this patient; observation is the appropriate management. A 35-year-old man comes in for evaluation because his wife thinks he looks yellow. He feels fine, his med- ical history is unremarkable, and he takes no medications. On review of systems, he has no weight loss, anorexia, fevers, chills, or abdominal pains.

These complex clinical and ultrastructural conditions constitute the final stage of EFP differin 15gr amex. EFP involves venous alterations, especially at the macrocirculatory level. The deter- mining pathogenic situation is recurrent edema of the adipose tissue with a concomitant venule–capillary permeability increase that unleashes the disease itself. In localized adiposity, the characteristic is adipocyte hypertrophy with preserved morphology, histochemistry, and biochemistry. The main cause of adipocyte hypertrophy is associated with genetic and hormone evolutionary factors. Hence, EFP may be considered as a pathological process of the adipose tissue, whereas localized adiposity is borderline functional because no regressive adipocytic or stromal alterations may be detected. Treatments should be different because etiopathogenesis and evolution are different. The term ‘‘cellulite’’ should be qua- lified somehow to avoid such confusions (59,60). In other words, localized adiposity and EFP are two different stages of closely related clinical and semiological events. It might be said that EFP occurs on a favorable bed: hypertrophy of some areas of adipose tissue, especially in the lower limbs. Such localized adiposity provides the basis for the development of EFP. Let us do without the term ‘‘cellulite’’ tout court, and substitute ‘‘cellulite’’ qualified by a specification of the pathology involved. There are also references in the literature to cellulite being derived from venous– lymphatic insufficiency, but this is not always the case. PATHOPHYSIOLOGY OF CELLULITE & 71 Because microcirculatory flow is slowed down, current literature mentions a stasis characteristic of hypotonic phlebopathy, because no sign of venous hypertension has been detected in this pathology.
