This region is densely packed with genes. These genes encodes two major proteins or antigens i.e., MHC I & MHC II. These proteins play an impoant role in the differentiation of foreign cells from host cell. Presence of these proteins is necessary for identification of host cells. Identification of the cells is impoant for immune responses. If the cell is recognised as self, the immune system will not mount an immune response against it. How does MHC helps in this ??? Cells continuously display small pieces of their own internal protein, carrying them, outsie the cell membrane where the immune system can see them. These peptides are just pieces of the normal proteins found inside the cell. These peptides are held together at the cell surface by major histocompatibility complex, which holds these peptides together for the immune system to examine them. Each persons immune system is customized early in life to ignore these peptides, so healthy cells are not able to trigger the immune system and they are left alone. But if any virus or other microorganism is multiplying inside the cell, the peptides synthesized by it also is displayed on the surface. The MHC displays these unusual (foreign) protein on the surface of the cell. The immune system is triggered because of these peptides, staing, a series of event that will eventually lead to killing of the cell containing foreign peptide. MHC is also the cause of tissue rejection during skin grafts and organ grafts. This is how the MHC protein got its name; the term histocompatibility refers to the difficulty of finding compatible grafts between a donor and a patient. Each person has their own collection of MHC molecules. If you graft a piece of skin that has a different collection of MHC types they will trigger the immune system to destroy the cell. So a compatible donor is needed such as a relative who has a similar collection of MHC molecules. MHC is also active against cancer Cancer cells, like normal cells, display pieces of their own protein on their surface. So if any of these proteins carries recognizable cancer mutations, this provides a signal to the immune system that something is wrong and the cell is killed. MHC plays role in activation of T helper cells (Th) MHC class II molecules are present on the membranes of dendritic cells, macrophages. These cell function as antigen presenting cell during immune response. They capture the antigen and present it to T helper cells. In response, the T helper cells secrete cytokines that stimulate B cell proliferation and antibody production. The impoant point about T helper cells is that they respond to only those antigens which have been presented to them by cells that have host matching MHC complex on the presenting cell. In general the antigen presenting cell .first phagocytoses the protein antigen and cleaves it to peptides in the lysosomes. These peptides are then extruded and attached to the presenting cell's surface MHC complex. T helper cells first, make sure, that these MHC class II molecules are host's own MHC and then responds appropriately. So, we can say that receptor on the T helper cell is thus responsive to the combination of antigen and host matching MHC complex on the presenting cell.

However, the use of these tools to cardiac imaging is severely limited because of motion aifacts produced by constantly in motion hea completing an entire cycle of contraction and relaxation in about 1 second.- So radiological cardiac imaging requires a 'window' of minimum cardiac motion to reduce motion aifacts and achieve meaningful images. The phase of minimum cardiac motion is although variable and depends on several factors especially hea rate and the chamber (i.e. right /left - atrium or ventricle) to be specifically imaged. However, the phase of minimum cardiac motion (= optimum phase for cardiac & coronary vessel imaging)."}

His postinfarction course is marked by congestive hea failure and intermittent hypotension. On the fouh day in hospital, he develops severe midabdominal pain. On physical examination, blood pressure is 90/60 mm Hg and pulse is 110 beats per minute and regular; the abdomen is soft with mild generalized tenderness and distention. Bowel sounds are hypoactive; stool Hematest is positive. Which of the following is the most appropriate next step in this patient's management?\nA) Barium enema\nB) Upper gastrointestinal series\nC) Angiography\nD) Ultrasonography", "output": "2, because In the absence of peritoneal signs, angiography is the diagnostic test of choice for acute mesenteric ischemia. Patients with peritoneal signs should undergo emergent laparotomy. Acute mesenteric ischemia may be difficult to diagnose. The condition should be suspected in patients with either systemic manifestations of aeriosclerotic vascular disease or low cardiac-output states associated with a sudden development of abdominal pain that is out of propoion to the physical findings. Because of the risk of progression to small-bowel infarction, acute mesenteric ischemia is an emergency and timely diagnosis is essential. Although patients may have lactic acidosis or leukocytosis, these are late findings. Abdominal films are generally unhelpful and may show a nonspecific ileus pattern. Since the pathology involves the small bowel, a barium enema is not indicated. Upper gastrointestinal series and ultrasonography are also of limited value. CT scanning is a good initial test, but should still be followed by angiography in a patient with clinically suspected acute mesenteric ischemia, even in the absence of findings on the CT scan. In addition to establishing the diagnosis in this stable patient, angiography may also assist with operative planning and elucidation of the etiology of the acute mesenteric ischemia. The cause may be embolic occlusion or thrombosis of the superior mesenteric aery, primary mesenteric venous occlusion, or nonocclusive mesenteric ischemia secondary to low-cardiac output states. A moality of 50% to 75% is repoed. The majority of affected patients are at high operative risk, but early diagnosis followed by revascularization or resectional surgery or both are the only hope for survival. Celiotomy must be performed once the diagnosis of aerial occlusion or bowel infarction has been made. Initial treatment of nonocclusive mesenteric ischemia includes measures to increase cardiac output and blood pressure. Laparotomy should be performed if peritoneal signs develop"}

Also in a team presentations, usually speakers stand as they speak; in panel discussions, usually speakers sit the whole time. Technically, a panel discussion consists of questions and answers only, and a symposium consists of a series of prepared speeches, followed by questions and answers. The chairman/ moderator must monitor time and manage questions. If each paicipant is making a speech for a set period of time, he should signal the speakers at the one minute to go mark and at the stop mark. If a speakers goes more than one or two minute he can stop them to gave the equal rights to each speakers. The chairman/ moderator must be a biased person; he is neither in our nor against the topic.

This patient most likely has difficulty in synthesizing which one of the following?\nA) Heme\nB) Creatine phosphate\nC) Cysteine\nD) Thymine", "output": "0, because The patient has acute intermittent porphyria, which is a defect in one of the early steps leading to heme synthesis. The buildup of the intermediate that cannot continue along the pathway leads to the dark urine, and it turns darker when ultraviolet (UV) light interacts with the conjugated double bonds in the molecule. Erythromycin is metabolized through an induced P450 system, which requires increased heme synthesis. This leads to metabolite buildup to the level where the abdominal pain appears. The defect in heme synthesis does not affect creatine phosphate, cysteine, thymine, or methionine levels."}

It is about 10% of total activity and is increased in obstructive jaundice and to some extent in metastatic carcinoma of liver.# Alpha-2 heat labile ALP is stable at 56degC; but loses its activity when kept at 65degC for 30 minutes. It is produced by hepatic cells. Therefore, exaggerated alpha-2 band suggests hepatitis. This liver iso-enzyme forms about 25% of total ALP.# Alpha-2 heat stable ALP will not be destroyed at 65degC, but is inhibited by phenylalanine. It is of placental origin, which is found in blood in normal pregnancy. An iso-enzyme closely resembling the placental form is characteristically seen in circulation in about 15% cases of carcinoma of lung, liver and gut and named as Regan iso-enzyme (after the first patient in whom it was detected) or carcinoplacental iso-enzyme. Chronic heavy smoking also increases Regan iso-enzyme level in blood. Normal level is only 1% of the total ALP.# Pre-beta ALP is of bone origin and elevated levels are seen in bone diseases. This is most heat labile (destroyed at 56degC, 10 min). Wheat germ lectin will precipitate bone isoenzyme. This constitutes about 50% of normal ALP activity.# Gamma-ALP is inhibited by phenylalanine and originates from intestinal cells. It is increased in ulcerative colitis.

Each episode, called an apnea, lasts long enough so that one or more breaths are missed, and such episodes occur repeatedly throughout sleep.> The standard definition of any apneic event includes a minimum 10 second interval between breaths, with either a neurological arousal (a 3-second or greater shift in EEG frequency, measured at C3, C4, O1, or O2), a blood oxygen desaturation of 3-4deg/: or greater, or both arousal and desaturation. Sleep apnea is diagnosed with an overnight sleep test called a polysomnogram, or a \"Sleep Study\".> Treatment: The most common treatment and arguably the most consistently effective treatment for sleep apnea is the use of a continuous positive airway pressure (CPAP) device, which 'splints' the patient's airway open during sleep by means of a flow of pressurized air into the throat. However the CPAP machine only assists inhaling whereas a BiPAP machine assists with both inhaling and exhaling, and is used in more severe cases. Medications like Acetazolamide lower blood pH and encourage respiration. Low doses of oxygen are also used as a treatment for hypoxia but are discouraged due to side effects."}

It also binds to the glucocorticoid receptor, but is only a weak anti-glucocorticoid relative to mifepristone, and has no relevant affinity to the estrogen, androgen and mineralocorticoid receptors. Phase II clinical trials suggest that the mechanism might consist of blocking or delaying ovulation and of delaying the maturation of the endometrium.Medical Uses* Emergency contraception: For emergency contraception, a 30mg tablet is used within 120 hours (5 days) after an unprotected intercourse or contraceptive failure. It has been shown to prevent about 60% of expected, pregnancies, and prevents more pregnancies than emergency contraception with levonorgestrel.* Treatment of uterine fibroids: Ulipristal acetate is used for preoperative treatment of moderate to severe symptoms of uterine fibroids in adult women of reproductive age in a daily dose of a 5mg tablet. Treatment of uterine fibroids with ulipristal acetate for 13 weeks effectively controlled excessive bleeding due to uterine fibroids and reduced the size of the fibroids.InteractionsUlipristal acetate is metabolized by CYP3A4 in vitro. Ulipristal acetate is likely to interact with substrates of CYP3A4, like rifampicin, phenytoin, St John's wort, carbamazepine or ritonavir. Therefore, concomitant use with these agents is not recommended. It might also interact with hormonal contraceptives and progestogens such as levonorgestrel and other substrates of the progesterone receptor, as well as with glucocorticoids.Adverse EffectsCommon side effects include abdominal pain and temporary menstrual irregularity or disruption. Headache and nausea were observed under long-term administration (12 weeks), but not after a single dose.ContraindicationsUlipristal acetate should not be taken by women with severe liver diseases because of its CYP-mediated metabolism. It has not been studied in women under the age of 18.Pregnancy: Unlike levonorgestrel, and like mifepristone, ulipristal acetate is embryotoxic in animal studies. Before taking the drug, a pregnancy must be excluded."}

The patient should be tested for which of the following ?\nA) HBV\nB) HCV\nC) EBV\nD) Parvovious", "output": "1, because Hepatitis C This is caused by an RNA flavivirus. Acute symptomatic infection with hepatitis C is rare. Most individuals are unaware of when they became infected and are identified only when they develop chronic liver disease. Eighty per cent of individuals exposed to the virus become chronically infected and late spontaneous viral clearance is rare. There is no active or passive protection against hepatitis C virus (HCV). Hepatitis C infection is usually identified in asymptomatic individuals screened because they have risk factors for infection, such as previous injecting drug use , or have incidentally been found to have abnormal liver blood tests. Although most people remain asymptomatic until progression to cirrhosis occurs, fatigue can complicate chronic infection and is unrelated to the degree of liver damage. Hepatitis C is the most common cause of what used to be known as 'non-A, non-B hepatitis'. If hepatitis C infection is left untreated, progression from chronic hepatitis to cirrhosis occurs over 20-40 years. Risk factors for progression include male gender, immunosuppression (such as co-infection with HIV), prothrombotic states and heavy alcohol misuse. Not everyone with hepatitis C infection will necessarily develop cirrhosis but approximately 20% do so within 20 years. Once cirrhosis has developed, the 5- and 10-year survival rates are 95% and 81%, respectively. One-quaer of people with cirrhosis will develop complications within 10 years and, once complications such as ascites develop, the 5-year survival is around 50%. Once cirrhosis is present, 2-5% per year will develop primary hepatocellular carcinoma. Ref Davidson edition23rd pg877"}

A biopsy of this mass is diagnosed as a moderately differentiated squamous cell carcinoma.

This patient's paraneoplastic syndrome is most likely the result of ectopic production of\nA) Parathyroid hormone\nB) Calcitonin\nC) Parathyroid hormone-related peptide\nD) Calcitonin-related peptide", "output": "2, because Symptoms not caused by either local or metastatic effects of tumors are called paraneoplastic syndromes. Bronchogenic carcinomas are associated with the development of many different types of paraneoplastic syndromes. These syndromes are usually associated with the secretion of ceain substances by the tumor cells. For example, ectopic secretion of ACTH may produce Cushing's syndrome, while ectopic secretion of antidiuretic hormone (syndrome of inappropriate ADH secretion) may produce hyponatremia. Hypocalcemia may result from the production of calcitonin, while hypercalcemia may result from the production of parathyroid hormone-related peptide (PTHrP), which is a normal substance produced locally by many different types of tissue. PTHrP is distinct from parathyroid hormone (PTH) patients with this type of paraneoplastic syndrome have increased calcium levels and decreased PTH levels. As a result of decreased PTH production, all of the parathyroid glands in these patients are atrophic. Other tumors associated with the production of PTHrP include clear cell carcinomas of the kidney, endometrial adenocarcinomas, and transitional carcinomas of the urinary bladder. Lung cancers are also associated with multiple, migratory venous thromboses. This migratory thrombophlebitis is called Trousseau's sign and is more classically associated with carcinoma of the pancreas. Hyperophic osteoahropathy is a syndrome consisting of periosteal new bone formation with or without digital clubbing and joint effusion. It is most commonly found in association with lung carcinoma, but it also occurs with other types of pulmonary disease. Erythrocytosis is associated with increased erythropoietin levels and some tumors, paicularly renal cell carcinomas, hepatocellular carcinomas, and cerebellar hemangioblastomas. It is not paicularly associated with bronchogenic carcinomas. Reference: Robbins & Cotran Pathologic Basis of Disease, 9edition."}
