It has a slow generation time of 4-6 weeks to obtain a colony of mycobacterium tuberculosis cholesterol range chart canada pravachol 10 mg without prescription. Cord factor which is a cell wall glycolipid component is aviable on virulent strains 2 cholesterol screening purchase pravachol 20mg otc. Tuberculosis heat shock protein is similar to human heat shock protein and may have a role in autoimmune reactions induced by M cholesterol medication raises blood pressure best 20 mg pravachol. Inhibition of acidification has been associated with urase secreted by the mycobacteria cholesterol over 300 pravachol 20mg online. Race: North American Indians, black Africans and Asians are much more susceptible than others Age: Extremes of ages due to imperfect immune responses Immunologic and other host factors immunocompromized patients are more liable to develop tuberculosis. First, the organisms are phagocytosed by alveolar macrophages and transported by these cells to hilar lymph nodes. Lyses of these macrophages results in the formation of caseating granuloma and direct toxicity to the mycobacteria may contribute to the necrotic caseous centers. The primary infection of sub-pleural lesion, the intervening macrophage reactions within accompanying lymphangitis and the hilar lymph nodes caseous lesions is called primary complex (often called a Ghon focus). T-cell mediated immune response induces hypersensitivity to the organisms and controls 95% of primary infection. This is associated with progressive fibrosis and calcification of persistent caseous debris. However, if the infected person is immunologically immature, as in a young child or immunocompromized (eg. Such persons lack the capacity to coordinate integrated hypersensitivity and cell- mediated immune responses to the organism and thus often lack the capacity to contain the infection. Granulomas are poorly formed or not formed at all, and infection progresses at the primary site in the lung, the regional lymph nodes or at multiple sites of disseminations. Progressive primary tuberculous pneumonia: commonly seen in children less than five years of age but it ours in adults as well in those with suppressed or defective immunity. Subpleural focus may discharge bacilli or antigen into the pleural cavity resulting in the development of pleural effusion. Hilar or mediastinal groups of lymph nodes enlargement with caseous necrosis that may result in: a. Obstruction of the bronchus by the enlarged lymph nodes leading to lobar collapse. The caseous hilar lymph node may penetrate the bronchial wall and resulting in rupture of the wall with pouring of caseous materials into the bronchus hence, tuberculosis broncho-pneumonia ensues. The caseous materials may be disseminated to other parts of the body via blood streams. Miliary tuberculosis It refers to disseminated sites that produce multiple, small yellow nodular lesions in several organs. The lungs, lymph nodes, kidneys, adrenals, bone marow, spleen, menings and liver are common sites for miliary lesions. Seeding of the bacilli in lungs, bones, kidneys, fallopian tubes, bladder, epididimis etc, that may persist in and their subsequent reactivation produces destructive, necrotizing granulmatious disease, sometimes known as end organ tuberculosis. Intestinal primary infection the primary complex is similar to that of the lungs the initial site may be in the gum with lymphatic spread of bacilli to the cervical lymph nodes the commonest location for the primary lesion is the illocaecal region with local mesenteric node involvement. Lymph nodes Tuberculous lymph adenitis is the most common type of extra pulmonary tuberculosis that frequently involves the cervical groups of lymph nodes with enlargement, and subsequent periadenitis followed by matting and eventual ulcerations if left untreated. Skin is also involved in various forms of tuberculosis Post -primary (secondary) tuberculosis Conventionally the term post-primary tuberculosis is used for lung infections occurring 5 years or more after the primary infection. The commonest sites for post primary tuberculosis are the posterior or apical segment of the upper lobe and the superior segment of the lower lobe and their predilection for the anatomy location is due to good ventilation. Hypersensitivity reaction is welldeveloped and it thus, restricts the granulomatous reactions locally. Pulmonary and bronchial arteries around caseous cavities are occluded by endarteritis obliterans where the wall of the artery may weaken resulting in aneurysm formation (mycotic aneurism) that may occasionally rupture and cause hemoptosis. Post primary (20) tuberculosis in endemic countries occurs due to re-infection or reactivation of previously residing bacilli. Infected sputa may be swallowed resulting in tuberculous ulcer in the larynx or small intestine Secondary amyloidosis is a common complication of chronic tuberculosis. Certain tissues are relatively resistant to tuberculous infection, so it is rare to find tubercles in the heart, skeletal muscle, thyrord and pancreas.

Hyperactivity/Inattention secondary to other (learning/developmental) disorders a cholesterol numbers chart explained generic pravachol 10 mg visa. Objectives 2 Through efficient cholesterol levels high risk buy discount pravachol 10 mg on line, focused which cholesterol ratio is most important cheap 20mg pravachol amex, data gathering: Determine whether there is family history for attention deficit or any of the co-morbid conditions cholesterol medication controversy buy 20mg pravachol mastercard. Determine whether there is evidence of development delay, genetic syndromes, encephalopathies, poisoning. Obtain (with consent) an education history (from teachers); physical examination should focus on ruling out underlying medical disorders (hearing, vision, mental status, neurologic disease). Select patients who require further medical investigation or psychological testing. The management of patients with hyperactivity/attention deficit disorder is resource intensive. The physician requires special knowledge and skill in how to access the needed resources. The management of patients with hyperactivity/attention deficit disorder may on occasion involve the use of medications that are considered controlled substances. Provincial licensing authorities may be involved in the regulation of such medications and may require the co-operation of the physician in regulating their use. The management of patients with hyperactivity/attention deficit disorder may involve a team structure that includes other health care workers, educators etc. This relationship and delegation of certain aspects of care must be based on respect and clear communication. Lower intestinal bleeding usually manifests itself as hematochezia (bright red blood or dark red blood or clots per rectum). Melena may be seen in 5 - 10% of patients with colorectal/small bowel bleeding and hematochezia may be seen with massive upper gastrointestinal bleeding. Objectives 2 Through efficient, focused, data gathering: Outline the diagnostic value/limitations of contrasting hematochezia and melena. The urgency of treatment and the nature of resuscitation depend on the amount of blood loss, the likely cause of the bleeding, and the underlying health of the patient. Objectives 2 Through efficient, focused, data gathering: Determine whether a bleeding diathesis may contribute to the bleeding. Early identification of colorectal cancer is important in preventing cancer-related morbidity and mortality (colorectal cancer is second only to lung cancer as a cause of cancer-related death). Rectal injuries and sexual abuse Key Objectives 2 List the key steps in the management of lower gastrointestinal bleeding in high-risk patients as resuscitation and assessment, localization, and diagnosis and treatment (early involvement of a gastroenterologist and surgeon is essential). Objectives 2 Through efficient, focused, data gathering: List indications for nasogastric tube aspiration and diagnose the most likely cause of hematochezia. List and diagnose the presence of associated drugs or medical conditions predisposing to the development of diverticulosis or colorectal cancer. List and interpret critical clinical and laboratory findings which are key in the processes of exclusion, differentiation, 2 and diagnosis: Select colonoscopy as the initial examination for diagnosis and treatment. Bleeding usually starts and stops unpredictably, but under certain circumstances may require immediate establishment of an airway and control of the bleeding. With massive hemoptysis/respiratory difficulty, once the patient is stabilized, refer promptly for bronchoscopy. Objectives 2 Through efficient, focused, data gathering: Differentiate between the causes of hemoptysis; determine the presence of prior lung, renal, or cardiac involvement. Identify presence of smoking, prior hemoptysis or family history of hemoptysis, infectious symptoms, upper airway or gastrointestinal symptoms; determine exposure to chemicals/asbestos, travel history, anticoagulants/platelet drugs; examine for skin rash, murmurs, deep venous thrombi. Conduct an effective initial plan of management for a patient with hemoptysis: 2 In the presence of massive hemoptysis (>200 ml/day), ensure adequacy of ventilation and hemodynamic stability first and consult a specialist. Outline the management of causes of hemoptysis which are not life threatening and do not require immediate referral to a specialist. Contrast the disproportionate amount of blood flow in the pulmonary arteries, almost the entire cardiac output but at low pressure, to the much smaller blood flow at high pressure through the bronchial arteries, usually one or two branches off the aorta for each lung. Despite this disproportion,>90% of the time, hemoptysis originates from the bronchial arteries. Identify the pulmonary arteries as supplying nutritive blood supply for the airways, hilar lymph nodes, visceral pleura, and some of the mediastinum.

Vitamin A deficiency Indevelopedcountries,vitaminA(retinol)deficiencyis seen as a complication of fat malabsorption when supplementation has been inadequate. Clinical mani festations under these circumstances are rare, except for impaired adaptation to dark light. It causes eye damage (xerophthalmia), which may progress from night blindness to corneal ulcerationandscarring. Prevention in developing countries with high prevalence is by giving young children a dose of vitamin A; in some countriesfoodisfortified.
