Immunophenotype The neoplastic cells closely resemble normal germinal center B cells, expressing CD19, CD 20, CD 10, surface Ig, and Bel 6. o Unlike CLL/SLL and mantel cell lymphoma, CD 5 is not expressed. o Bcl 2 is expressed in more than 90% of cases, in distinction to normal follicular center B cells, which are Bcl 2 negative, and mantel cell lymphoma cells which express BCL 1 (cyclin D1). Molecular pathogenesis o The hallmark of follicular lymphoma is (14:18) translocation that juxtaposes the IgH locus on chromosome 14 and the Bel 2 locus on chromosome 18. Bcl 2 antagonizes the apoptosis and promotes the survival of follicular lymphoma cells --> while normal germinal centers contain numerous B cells undergoing apoptosis, follicular lymphoma is characteristically devoid of apoptotic cells"

{
"from": "gpt",
"value": "Answer: Caecum\nExplanation: Iron is absorbed from upper small intestine mainly duodenum. In diet, iron occurs in two forms, haem iron and inorganic (non-haem) iron.\n\nHaem iron is better absorbed than inorganic iron, but the major fraction of diet is inorganic iron. Inorganic iron is mostly in ferric form; needs to be reduced to ferrous form because iron is absorbed in ferrous form.\n\nAfter absorption, ferrous form is once again oxidized to ferric form inside enterocytes.\n\nA fraction of absorbed iron is rapidly delivered to plasma transferrin.\nHowever, most of the iron is deposited in the enterocytes as ferritin,\nsome to be transferred more slowly to plasma transferrin, and some to be lost when senescent mucosal cells (enterocytes) are sloughed into the intestine.\n\nIron absorption is regulated according to the demand, e.g., when there is iron deficiency, absorption increases.\n\nThis regulation is mediated by “iron metabolism regulatory hormone”, i.e., hepcidin that inhibits iron absorption. When there is iron deficiency, the concentration of hepcidin falls and there is increase iron absorption. Hepcidin also decreases the release of iron from storage sites."

Infusion solutions should be changed after hours.# Dosage typically begins at 0.5 microgram/kg/min and may be increased up to 10 g/kg/min.# The drug is given by intravenous infusion and arterial blood pressure monitored via intra-arterial recording.Drug ClassMechanism of actionEffectsIndicationsToxicitiesNotesAngiotensin II-receptor blockers: Losartan, CandesartanBlock angiotensin II receptorsSame as ACE inhibitorsSame as ACE inhibitorsFetal renal toxicity no coughNot as well studied as ACEIs, but seem to have same efficacyVasodilators: Nitroglycerin Nitroprusside Isosorbide dinitrate Hydralazine| nitric oxide -cGMP - vasodilationNitroclycerin, isosorbide dinitrate predominantly venodilatorsNitroprusside; dilation of arteries = veinsCHF, HTN, angina, pulmonary edemaTachycardia, headache, hypotensionNitroprusside, nitroglycerin: used in acute HF Hydralazine, isosorbide dinitrate: used in chronic HF"

Proteinuria is invariably present but is not as specific. White blood cell casts are indicative of interstitial nephritis or infection, and hyaline casts are nonspecific findings."

Maheshwari ortho 3rd/pg. 112; Current Ortho/ Ch.3.)Femoral Neck FractureIntroduction:# There are two types of of the neck of femur .Intracapsular &Extracapsular# Most of the Femoral neck fractures are intracapsular fractures (as a matter of convention, the term fracture of the neck of femur' is used for intracapsular fracture of the neck).# The extracapsular are usually called inter-trochanteric .Classification# A. Anatomical classification# B. Pauwel's classification# C. Garden's classificationGarden classification for acute fractures of femoral neck is the most widely used system:Garden classification for fractures of femoral neckType 1Valgus impaction of the femoral headType 2Complete but nondisplacedType 3Complete fracture, displaced less than 50%Type 4Complete fracture displaced greater than 50%c/f:# The involved extremity may be slightly shortened and externally rotated.# Tenderness in groin# Attempted hip movements painful, and asso with sever spasm# Active straight leg rising not possible.Complications:# 1. Non-union (in 30-40% of IC ).# 2. AVN: high risk of nonunion or avascular necrosis of the femoral head due the unusual vascularization of the femoral head and neck. The incidence of avascular necrosis increases with the amount of fracture displacement and the amount of time before the fracture is reduced.# 3. OARx:# This is rightly termed as \"unsolved \" because of the high incidence of complications.# This invariable needs operative Rx.# An impacted fracture is Rxed conservatively in all age groups (hip spica in childen and Thomas splint in adults).# Unimpacted or displaced fracture:- < 60 yrs: internal fixation.- > 60 yrs: head excised and replaced by prosthesis done as a primary procedure.- In few younger patients, especially if preesenting late, open reduction of is done.- Internal fixation can be done using any of the following implant:# Multiple cancellous screws - most commonly used.# Dynamic hip screws (DHS)# Multiple Knowle's pins/More's pins - used in children.# SP nail - not popular now.- At some centres in general an inter-trochanteric osteotomy (McMurray's osteotomy is preferred).- Hemiarthroplasty is used for elderly patients & Austin Moore prosthesis is used most commonly. This cannot be used as a method of Rx in younger patients as prosthesis becomes loose over a period of time (8-10 yrs).Meyer's procedure ( reduced by exposing it from behind and it is fixed with multiple screws and supplemented with vascularised muscle pedicle bone graft). It is used in treating the fractures presenting late and those with significant communition. It is also used for non-union of the femoral neck .Additional Educational points:The vascular supply of the femoral head is also of paramount importance. There are three main sources of vascular supply:1) The retinacular vessels arising from the lateral femoral circumflex artery and the inferior metaphyseal artery and then running beneath the synovium along the neck, which they penetrate proximally both anteriorly and posteriorly;2) The interosseous circulation crossing the marrow spaces from distal to proximal; and3) Unreliably, the ligamentum teres artery."

This resistance to tearing is known as tear strength. Polysulfide impression materials have high tear strength that allows them to be removed from undercuts without tearing.\nHydrocolloids, on the other hand, lack adequate tear strength. Hence, to prevent tearing, most impressions have to be removed with a snap motion, parallel to the long axis of the teeth."

"from": "gpt",
"value": "Answer: Positive feed back\nExplanation: Undamped oscillations are oured by a high gain and a long dead time. The high gain makes it likely that the response may overshoot the desired level. The long dead time allows the overshoot to reach a considerable value before the overshoot is corrected by the negative feedback mechanism. Thus, the oscillations continue. A good example of undamped oscillations is Cheyne - Stokes' breathing. SERVOMECHANISM: In some control systems, the set point is not a fixed entity. If the set point changes from time to time, the system is called a servomechanism. The stretch reflex which regulates muscle length is an example of a servo mechanism. The stretch reflex has a variable gain. The initial high gain increases the speed with which most of the response is completed. The low gain later reduces the oscillations in the response."

},
{
"from": "gpt",
"value": "Answer: Digoxin\nExplanation: Milrinone, commonly known and marketed under the brand name Primacor, is a medication used in patients who have hea failure. It is a phosphodiesterase 3 inhibitor that works to increase the hea's contractility and decrease pulmonary vascular resistance. Milrinone also works to vasodilate which helps allete increased pressures (afterload) on the hea, thus improving its pumping action. While it has been used in people with hea failure for many years, studies suggest that milrinone may exhibit some negative side effects that have caused some debate about its use clinically Overall, milrinone suppos ventricular functioning of the hea by decreasing the degradation of cAMP and thus increasing phosphorylation levels of many components in the hea that contribute to contractility and hea rate. Milrinone use following cardiac surgery has been under some debate because of the potential increase risk of postoperative atrial arrhythmias.] However, in the sho term milrinone has been deemed beneficial to those experiencing hea failure and an effective therapy to maintain hea function following cardiac surgeries. There is no evidence of any long term beneficial effects on survival.In critically ill patients with evidence of cardiac dysfunction there is limited good quality evidence to recommend its use Cyclic adenosine monophosphate (cAMP) causes increased activation of protein kinase A (PKA). PKA is an enzyme that phosphorylates many elements of the contractile machinery within the hea cell. In the sho term this leads to an increased force of contraction. Phosphodiesterases are enzymes responsible for the breakdown of cAMP. Therefore, when phosphodiesterases lower the level of cAMP in the cell they also lower the active fraction of PKA within the cell and reduce the force of contraction. Milrinone is a phosphodiesterase-3 inhibitor. This drug inhibits the action of phosphodiesterase-3 and thus prevents degradation of cAMP. With increased cAMP levels there is an increase in the activation of PKA. This PKA will phosphorylate many components of the cardiomyocyte such as calcium channels and components of the myofilaments. Phosphorylation of calcium channels permits an increase in calcium influx into the cell. This increase in calcium influx results in increased contractility. PKA also phosphorylates potassium channels promoting their action. Potassium channels are responsible for repolarization of the cardiomyocytes therefore increasing the rate at which cells can depolarize and generate contraction. PKA also phosphorylates components on myofilaments allowing actin and myosin to interact more easily and thus increasing contractility and the inotropic state of the hea. Milrinone allows stimulation of cardiac function independently of b-adrenergic receptors which appear to be down-regulated in those with hea failure. Ref Davidson 23rd edition pg 467"

Harrison's Medicine 18th/ Chapter 144., KDT 6th/682).........Sulphacetamide eye drops used for ophthalmic neonatorum.The SULFONAMIDES may be classified into 3 groups on the basis of the rapidity with which they are absorbed and excreted: (1) agents that are absorbed and excreted rapidly, such as sulfisoxazole and sulfadiazine: (2) agents that are absorbed very poorly when administered orally and are active in the bowel lumen, such as sulfasalazine: (3) agents that are used topically, such as sulfacetamide, mafenide. and silver sulfadiazine: and (4) long-acting sulfonamides, such as sulfadoxine. that are absorbed rapidly but excreted slowly.SULFONAMIDESRapidly Absorbed And Eliminated SulfonamidesSulfisoxazole.Sulfamethoxazole.Sulfadiazine.Sulfisoxazole is a rapidly absorbed and excreted sulfonamide with excellent antibacterial activity.Since its high solubility eliminates much of the renal toxicity inherent in the use of older sulfonamides, it has essentially replaced the less-soluble agents.Sulfisoxazole is bound extensively to plasma proteins.Sulfisoxazole currently is preferred over other sulfona- mides by when a rapidly absorbed and rapidly excreted sulfonamide is indicated.Sulfamethoxazole is a close congener of sulfisoxazole, but its rates of enteric absorption and urinary excretion are slower.It is administered orally and employed for both systemic and urinary tract infections.Precautions must be observed to avoid sulfamethoxazole crystalluria.The uses of sulfamethoxazole are the same as sulfisoxazole.Sulfadiazine given orally is absorbed rapidly from the GI tract, and peak blood concentrations are reached within 3 to 6 hours after a single dose.About 15% to 40% of the excreted sulfadiazine is in acetylated form. In adults and children who are being treated with sulfadiazine, every precaution must be taken to ensure fluid intake adequate to produce a urine output of at least 1200 ml in adults.Poorly Absorbed Sulfonamides.Sulfasalazine is very poorly absorbed from the Gl tract.It is used in the therapy of ulcerative colitis and regional enteritis, but relapses tend to occur in about one-third of patients who experience a satisfactory initial response.Corticosteroids are more effective in treating acute attacks, but sulfasalazine is preferred to corticosteroids for the treatment of patients who are mildly or moderately ill with ulcerative colitis. The drug also is being employed as the first approach to treatment of relatively mild cases of regional enteritis and granulomatous colitis. Sulfasalazine is broken down by intestinal bacteria to sulfapyridine, an active sulfonamide that is absorbed and eventually excreted in the urine, and 5-aminosalicylate, which reaches high levels in the feces. 5-Aminosalicylate is the effective agent in inflammatory bowel disease, whereas sulfapyridine is responsible for most of the toxicity. Toxic reactions includeHeinz-body anemia, acute hemolysis in patients with glucose-6-phosphate dehydrogenase deficiency, and agranulocytosis. Nausea, fever, arthralgias, and rashes occur in up to 20% of patients treated with the drug; desensitizationhas been an effective treatment. Sulfasalazine can cause a reversible infertility in males owing to changes in sperm number and morphology.Long-Acting Sulfonamides.SulfadoxineIt has a particularly long half-life (7 to 9 days).It is used in combination with pyrimethamine for the prophylaxis and treatment of malaria caused by mefloquine - resistant strains of Plasmodium falciparum.Because of severe and sometimes fatal reactions, including the Stevens-Johnson syndrome, the drug should be used for prophylaxis only where the risk of resistant malaria is high.Sulfonamides for Topical Use.Sulfacetamide.Solutions of the sodium salt of the drug are employed extensively in the management of ophthalmic infections.Although topical sulfonamide for most purposes is discouraged, its advantage is it penetrates into ocular fluids and tissues in high concentration. Sensitivity reactions to sulfacetamide are rare, but the drug should not be used in patients with known hypersensitivity to sulfonamides.Silver sulfadiazine inhibits the growth in vitro of nearly all pathogenic bacteria and fungi, including some species resistant to sulfonamides.The compound is used topically to reduce microbial colonization and the incidence of infections of wounds from burns.It should not be used to treat an established deep infection.Adverse reactions burning, rash, and itching are infrequentMafenide.When applied topically, it is effective for the prevention of colonization of burns by a large variety of gram-negative and grampositive bacteria. It should not be used in deep infection. Superinfection with Candida may be problem. Mafenide is rapidly absorbed systemically and converted to poro-carboxybenzenesulfonamide.Adverse effects include intense pain at sites of application, allergic reactions, and loss of fluid by evaporation from the burn surface because occlusive dressings are not used.Metabolic acidosis with compensatory tachypnea and hyperventilation may ensue; these effects limit its usefulness."
