The regulation of blood glucose concentration (through negative feedback) illustrates how the endocrine system maintains homeostasis by the action of antagonistic hormones treatment interstitial cystitis effective 4 mg avandia. Bundles of cells in the pancreas called the islets of Langerhans contain two kinds of cells treatment 1st degree av block buy avandia 4 mg, alpha cells and beta cells medicine to help you sleep effective avandia 4mg. These cells control blood glucose concentration by producing the antagonistic hormones insulin and glucagon medicine buddha mantra purchase 4mg avandia. When the concentration of blood glucose raises such in after eating, beta cells secret insulin into the blood. Liver and muscle cells convert glucose to glycogen, for short term storage, and adipose cells convert glucose to fat. In response, glucose concentration decreases in the blood, and insulin secretion discontinues through negative feedback from declining levels of glucose. When the concentration of blood glucose drops such as during exercise, alpha cells secrete glucagon into the blood. Glucagon also stimulates the production of ketone bodies from amino acids and fatty acids. When blood glucose levels return to normal, glucagon secretion discontinues through negative feedback. Another example of antagonistic hormones occurs in the maintenance of Ca2+ ion concentration in the blood. Thyroid gland the Thyroid gland is one of the largest endocrine glands in the body. It is positioned on the neck just below the Larynx and has two lobes with one on either side of the trachea. It is involved in the production of the hormones T3 (triiodothyronine) and T4 (thyroxine). The thyroid also produces and releases the hormone calcitonin (thyrocalcitonin) which contributes to the regulation of blood calcium levels. Thyrocalcitonin or calcitonin decreases the concentration of calcium in the blood. A deficiency of iodine in the diet leads to the enlargement of the thyroid gland, known as a simple goiter. Hyperthyroidism leads to a condition known as exophthalmic goiter, characterized by weight loss as well as hyperactive and irritable behavior. The thyroid gland is a two-lobed gland that manifests a remarkably powerful active transport mechanism for up-taking iodide ions from the blood. As blood flows through the gland, iodide is converted to an active form of iodine. Following its formation, the thyroxine becomes bound to a polysaccharide-protein material called thyroglobulin. The normal thyroid gland may store several weeks supply of thyroxine in this bound form. An enzymatic splitting of the thyroxine from the thyroglobulin occurs when a specific hormone is released into the blood. A variety of bodily defects, either dietary, hereditary, or disease induced, may decrease the amount of thyroxine released into the blood. The most popular of these defects is one that results from dietary iodine deficiency. This is a futile attempt to synthesize thyroid hormones, for iodine levels that are too low. Normally, thyroid hormones act via a negative feedback loop on the pituitary to decrease stimulation of the thyroid. In goiter, the feedback loop cannot be in operation - hence continual stimulation of the thyroid and the inevitable protuberance on the neck. Today, the incidence of goiter has been drastically reduced by adding iodine to table salt. Thyroxine serves to stimulate oxidative metabolism in cells; it increases the oxygen consumption and heat production of most body tissues, a notable exception being the brain. The most likely explanation being that thyroxine promotes the effects of growth hormone on protein synthesis. Thyroxine also plays a crucial role in the closely related area of organ development, particularly that of the central nervous system.

In a patient with severe symptoms of claudication that are interfering with his or her lifestyle treatment scabies quality avandia 4 mg, intervention is indicated treatment innovations best avandia 4 mg. Axillofemoral bypass grafts are an alternative to aortofemoral procedures medicine during the civil war generic 2 mg avandia, but have a lower 5-year patency rate and should be reserved for high-risk patients with bilateral iliac disease or an infected aortic aneurysm or graft medicine for vertigo order avandia 4mg. In a young, healthy patient with unilateral iliac artery occlusive disease, when angioplasty is not a treatment option, an aortofemoral bypass offers excellent long-term relief. Aortobifemoral bypass, while clearly the most risky of the treatment options offered, provides the best long-term patency. In elderly patients with severe comorbidities who are considered at high risk for complications, extra-anatomic bypasses (femorofemoral or axillofemoral bypasses) offer fair long-term patencies while not subjecting the patient to the risks of general anesthesia. Femorofemoral bypass offers the additional benefit of not disturbing sexual function; however, femorofemoral bypass is not an option in a patient with bilateral iliac artery disease. Neither common femoral and profunda femoral endarterectomies nor femoropopliteal bypass is beneficial in this patient who has aortoiliac disease. Which of the following is the recommended treatment for stage A (superficial and submucosal) transitional cell carcinoma of the bladder Which of the following is the optimal management of bilateral undescended testicles in an infant Chorionic gonadotropin therapy for 1 month; operative placement into the scrotum before age 2 if descent has not occurred c. Observation until age 2; operative placement into the scrotum if descent has not occurred d. Observation until age 5; if no descent by then, plastic surgical scrotal prostheses before the child enters school. No therapy; reassurance of the parent that full masculinization and normal spermatogenesis are likely even if the testicle does not fully descend 436. Which of the following is the most accurate method in obtaining a diagnosis of testicular cancer On physical examination, he is noted to have a high-riding, firm, and markedly tender left testis. Manual detorsion of the left testicle with external rotation toward the thigh; orchiopexy if the condition recurs b. Manual detorsion of the left testicle with internal rotation toward the thigh; orchiopexy if the condition recurs c. A 45-year-old woman presents with a 7-cm renal cell carcinoma with radiologic evidence of abdominal lymph node involvement with no distant metastases. A 60-year-old man seeks medical attention because of recurrent urinary tract infections. The patient also reports a history of increasing difficulty in urination (decreased flow, straining, and hesitancy) over the last several months. The left ureter is partially transected (50% of circumference) during the course of a difficult operation on an unstable, critically ill patient. Placement of an external stent through the proximal ureteral stump with delayed reconstruction b. Placement of a catheter from the distal ureter through an abdominal wall stab wound d. Immediate placement of a Foley catheter through the urethra into the bladder to align and stent the injured portions c. Immediate reconstruction of the ruptured urethra after initial stabilization of the patient d. Immediate exploration of the pelvis for control of hemorrhage from pelvic fracture and drainage of pelvic hematoma. Upon further questioning he also complains of frequency, urgency, dysuria, and a decreased urinary stream. Digital rectal examination demonstrates exquisite tenderness on the anterior aspect. Laboratory examination reveals leukocytosis and findings on urinalysis are consistent with a bacterial infection. It is most prevalent among men with a history of heavy smoking and is usually multifocal and superficial, even when recurrent. When the disease is still superficial, transurethral resection of visible lesions and intravesicular chemotherapy are most often recommended.

Seizure occurs as part of the initial presentation of bacterial meningitis medicine man trusted avandia 4mg, or during the course of the illness in 20-40 % of patients In Meningococcal meningitis of sudden onset with severe course symptoms 8 days post 5 day transfer 4 mg avandia, patients develop diffuse erythromatus maculopapular rash which rapidly becomes petechial medicine questions 2 mg avandia, purpural or bullos lesions 3 medications that cannot be crushed avandia 4 mg. The petichiae are found on the trunk, lower extremities, in the mucous membrane and the conjunctiva, and occasionally on the palms and soles. Viral encephalitis Learning Objective: At the end of this unit the student will be able to 1. Definition: Inflammation of the brain parenchyma, with or without involvement of the meninges, caused by virus. Most common focal findings are aphasia, ataxia, hemiparesis (with hyperactive tendon reflexes), involuntary movements and cranial nerve deficits. Brain biopsy: reserved for patients with unclear diagnosis, lack of response to therapy and who have abnormalities on imaging techniques. They overlap with each other, may affect many organ systems, and often respond to immunosuppressives. Circulating immune complexes and autoantibodies cause tissue damage and organ dysfunction. The potential of the synovial inflammation to cause cartilage damage and bone erosion and subsequent changes in joint integrity is the hall mark of the diseases. Women are more affected than men with F: M ratio of 3:1 the prevalence increases with age and, and the sex difference diminishes in the older age group. Morning stiffness which lasts greater than 1 hr, which is a feature of inflammatory arthritis is a common complaint. Axial involvement is limited to cervical spines; Atlantoaxial ligament involvement, in the cervical spine can lead to instability between C1 and C2 vertebrae and potential neurologic complaints Commonly affected joints are:- Joint deformities: with persistent inflammation, a variety of characteristic joint changes develop due to damage or weakening of ligaments, tendons and joint capsule. However, occasionally they may be the major evidence of disease activity and source of morbidity. More often, these manifestation occur in patients who have high titer of rheumatoid factor and patients who have more severe and established diseases a) Rheumatoid nodules: are the most common features of extraarticular diseases and are found in 20-25 % of patients. These firm subcutaneous masses typically are found in areas on periarticular structures and on areas exposed to of repetitive trauma. Myocarditis and Valvular dysfunction are rare findings 568 Keratoconjuctivitis sicca is seen in 10% -15 % of rheumatoid arthritis patients who have a secondary form of Sjogren syndrome Scleritis or episcleritis occur less common Pleuritis and pleural effusion may be seen is some patients. Intestinal fibrosis Rheumatoid nodules may appear on the lung, single or multiple. It is typically present in 60 % of patients in the first year and 80% of patients with long standing diseases. Note that 30 -40 % of patients with rheumatoid arthritis may be sero-negative for Rheumatoid factor. Late: sustained inflammation leads to loss of bones at joint margins (erosion) and joint space narrowing as a result of cartilage loss and joint deformity. Short term: Controlling pain and reducing inflammation without causing undesired side effects 2. These agents are rapidly effective in alleviating pain and symptoms, but there effect on long term disease progression is minimal. These drugs may be used singly mostly, but they may be prescribed in combinations in patients with bad prognosis or refractory diseases. Systemic sclerosis (Scleroderma) It is defined as a connective tissue characterized by widespread small vessel obliteration disease and fibrois of the skin and multiple internal organs. Some patients may have fulminant course that acute respiratory failure or myoglobinurin acute renal failure can ensue. Gout Learning objectives: at the end of this lesson the student will be able to: 1) Define Gout 2) Describe the etiology and pathogenesis of Gout 3) Identify the clinical features of Gout 4) Understand the diagnostic approach and investigations for Gout 5) Understand the management principles of different types Gout Definition: A group of disorders of purine metabolism that are characterized by serum uric acid elevation (hyperuricemia), urate deposits in articular or extraarticular tissues.
