1e860791-b860-4cb7-a19d-90b7b8031150 | A 4-month-old infant has undergone surgical treatment for meningo myelo encephalocele. A CT tomogram of head was made immediately after birth (see Figure below). At birth, an operation was carried out in the posterior cranial fossa to partially replace brain cerebellar contents to an intracranial position.

| single | Ref: Robbins Pathologic Basis of Disease, 8'k edition. & Bailey and Love's Short Practice of Surgery 25th EditionExplanation:INSULINOMAfi-cell tumors (insulinomas) are the MC of pancreatic endocrine neoplasms.They may be responsible for the elaboration of sufficient insulin to induce clinically significant hypoglycemia.The characteristic triad of clinical symptomsHypoglycemia (Glucose levels < 50 mg/dL)CNS manifestations such as confusion, stupor, tremor and loss of consciousnessS ymptoms precipitated by fasting or exercise and are promptly relieved by feeding or glucose administrationClinical featuresProfound hypoglycemia during fasting or after exercise.Signs and symptoms of neuroglycopeniaAnxietyTremorConfusionObtundationSympathetic response (Hunger, Sweating, and Tachycardia)Whipple's triad refers to the clinical criteria for the diagnosis of insulinoma:- Hypoglycemic symptoms during monitored fasting.- Blood glucose levels less than 50 mg/dL. and- Relief of symptoms after administration of intravenous glucose.Factitious hypoglycemia (excess exogenous insulin administration) and postprandial reactive hypoglycemia must be excluded. (Estimation of C peptide will differentiate)In insulinoma, C peptide levels are increased but in Factitious hypoglycemia, it is decreasedMorphologyInsulinomas are most often found within the pancreas and are generally benign.Most are solitary, although multiple tumors may be encountered.Bona fide carcinomas, making up only about 10% of cases, are diagnosed on the basis of local invasion and distant metastases.On rare occasions an insulinoma may arise in ectopic pancreatic tissue.In such cases, electron microscopy reveals the distinctive granules of |3.Solitary tumors are usually small (<2 cm in diameter) and are encapsulated, pale to red- brown nodules located anywhere in the pancreas.Histologically, these benign tumors look remarkably like giant islets, with preservation of the regular cords of monotonous celts and their orientation to the vasculature.Deposition of amyloid in the extracellular tissue is a characteristic feature.ImagingDynamic CT scanning at 5-mm intervals with oral and intravenous contrast is the initial localizing test for insulinoma, with success in 35-85% of cases.Endoscopic ultrasound is also effective but is operator dependentIndium-111 (111 In)-octreotide scintigraphy is less effective (approximately 50%) for localization of insulinoma than other islet cell tumors because insulinomas typically have few somatostatin receptors.Selective arteriography with observation of a tumor "blush'- is the single best diagnostic study for the primary tumor and hepatic metastases. If a tumor is still not identified, regional localization to the head. body, or tail of the pancreas can be accomplished by portal venous sampling for insulin or by calcium angiography.Calcium angiography involves injection of calcium into selectively catheterized pancreatic arteries and measurement of plasma insulin through a catheter positioned in a hepatic vein.TreatmentIt is surgical in nearly all cases.Use of intraoperative ultrasonography greatly facilitates identification of small tumors, especially those located in the pancreatic head or uncinate process.Most insulinomas can be enucleated from surrounding pancreas, although those in the body or tail may require resection.In general, blind pancreatectomy should NOT be performed when the tumor cannot be identified. Approximately 5% of insulinomas are malignant, and 10% are multiple (usually in association with MEN type I).Medical treatment for insulinoma with diazoxide. verapamil, or octreotide has limited effectiveness but may be used in preparation for surgery or for patients unfit for surgery. | Surgery | Pathophysiology - Pancreatic Endocrine Tumors |

bccc793d-a17d-4cab-a32a-3291bd629a7b | Which of the following is a superantigen | Cholera toxin | Diphtheria toxin | TSST | Vero-cytoxin | 2c
| single | Superantigens
Certain species of infectious microorganisms produce powerful,
immunostimulatory and disease-causing toxins called superantigen, so called because of their ability' to a polyclonally active large fraction ( up to 20% ) of T cell population.
Superangens are potent acvators of T-lymphocytes.
Superangens smulate very large numbers of T cells, without relaon to their epitope specificity'.
This leads to an excessive and dysregulated immune response with release of cytokines IL - 1, IL - 2, TNF - α and IF - γ.
Conventional antigens bind to MHC class I or II molecules in the groove
of the β dimer (T cell receptor). In contrast, superantigen bind directly to the lateral portion of TCR β chain and MHC class II β chain, and stimulate T cells solely on γ β gene segment utilized
independent of the D, J and γ aα - sequences present → γ β restricted T cell mitogens.
Superantigens are capable of giving up to 20% of the peripheral T-cell pool,
whereas conventional antigens activate < 1 in 10, 000.
Examples of superantigen Staphylococcal toxic shock syndrome toxin □ Certain nonhuman retroviral proteins,
Staphylococcal enterotoxins □ Yersinia pseudotuberculosis Staphylococcal exfoliative (erythrogenic) toxin □ Mycoplasma arthritis. Streptococcal toxic shock syndrome toxin □ Mouse mammary tumor virus. | Microbiology | null |

| multi | Pyogenic organisms, predominantly Staphylococcus aureus, cause tissue necrosis and suppuration. Pus is composed of dead and dying white blood cells, predominantly neutrophils, that have succumbed to bacterial toxins. An abscess is surrounded by an acute inflammatory response composed of a fibrinous exudate, oedema and the cells of acute inflammation. Granulation tissue (macrophages, fibroblasts and new blood vessel proliferation) forms later around the suppurative process and leads to collagen deposition. If it is not drained or resorbed completely, a chronic abscess may result. If it is partly sterilised with antibiotics, an antibioma may form.

In the intestine, it slows emptying of the stomach and stimulates the release of insulin from the pancreas.Pancreatic polypeptide is a 36-amino acid peptide secreted by islet cells of the pancreas in response to a meal and of unceain physiologic function;glucagon a polypeptide hormone secreted by the alpha cells of the islets of Langerhans in response to hypoglycemia or to stimulation by growth hormone. It increases blood glucose concentration by stimulating glycogenolysis in the liver and can be administered parenterally to relieve severe hypoglycemia from any cause, especially hyperinsulinism.Somatostatin is a cyclic tetradecapeptide hormone and neurotransmitter that inhibits the release of peptide hormones in many tissues. It is released by the hypothalamus to inhibit the release of growth hormone (GH, somatotropin) and thyroid stimulating hormone (TSH) from the anterior pituitary; it is also released by the delta cells of the islets of Langerhans in the pancreas to inhibit the release of glucagon and insulin and by the similar D cells in the gastrointestinal tract.Ref: Ganong&;s review of medical physiology;24th edition; page no-433 | Physiology | Endocrinology |

| multi | Answer is B (Presence of Hypeonic Contents in small intestine) DUMPING SYNDROME refers to a syndrome of abdominal and vasomator symptoms which results from dumping of food stuffs with a high osmotic load, front the stomach, into the small bowel. Loss of storage capacity of stomach and ablation, by pass or destruction of pylorus, results in rapid emptying of hyperostnolar chyme into duodenummm and small intestine. Extracellular fluid then shifts into the intestinal lumen to restore isotonicity resulting in decreased intravascular volume, which gives rise to the vasomotor symptoms. Note that while reduced gastric capacity contributes, option (b) is a more accurate answer. Dumping Syndrome is actually of two types: Early dumping syndrome (as described above) Late dumping syndrome: This is Reactive hypoglvcemiae. The carbohydrate load in thesmall intestine later causes a rise in plasma glucose, which in turn causes insulin levels to rise causing a secondary hypoglycemia. | Medicine | null |

| single | (A) Diffuse large B-cell lymphoma (DLBCL or DLBL)[?]Diffuse Large B-Cell LymphomaoDiffuse large B-cell lymphoma (DLBCL) is the most common form of NHL.oEach year in the United States there are about 25,000 new cases.oThere is a slight male predominance. The median patient age is about 60 years, but DLBCL also occurs in young adults and children. Germinal centre or post germinal center B celloDiverse chromosomal re-arrangements, most often BC26 (30%), BCL2 (10%), or C-MYC (5%).oAll ages, most common in Adults, 30% extranodal, aggressiveoTHC positive for CD10, CD20, CD10 & BCL6oPathogenesis:-Genetic, gene expression profiling, and immunohistochemical studies indicate that DLBCL is molecularly heterogeneous.-One frequent pathogenic event is dysregulation of BCL6, a DNA-binding zinc-finger transcriptional repressor that is required for the formation of normal germinal centers.-About 30% of DLBCLs contain various translocations that have in common a breakpoint in BCL6 at chromosome 3q27.-Acquired mutations in BCL6 promoter sequences that abrogate BCL6 autoregulation (an important negative-regulatory mechanism) are seen even more frequently.oImmunophenotype:-These mature B-cell tumors express CD19 and CD20 and show variable expression of germinal center B-cell markers such as CD10 and BCL6. Most have surface Ig.oSpecial Subtypes: Immunodeficiency-associated large B-cell lymphoma, Primary effusion lymphomaoClinical Features:-DLBCL typically presents as a rapidly enlarging mass at a nodal or extranodal site.-It can arise virtually anywhere in the body.-Waldeyer ring, the oropharyngeal lymphoid tissue that includes the tonsils and adenoids, is involved commonly.-Primary or secondary involvement of the liver and spleen may take the form of large destructive masses.-Extranodal sites include the gastrointestinal tract, skin, bone, brain, and other tissues.-Bone marrow involvement is relatively uncommon and usually occurs late in the course.-Rarely, a leukemic picture emerges.Other Options[?]Hairy cell Leukemia:-This rare but distinctive B-cell neoplasm constitutes about 2% of all leukemias.-Hairy cell leukemias are associated in more than 90% of cases with activating point mutations in the serine/threonine kinase BRAF, which is positioned immediately downstream of RAS in the MAPK signaling cdscade[?]Burkitt's lymphoma:-Within the category of Burkitt Lymphoma fall (1) African (endemic) Burkitt lymphoma, (2) sporadic (non-endemic) Burkitt lymphoma, and (3) a subset of aggressive lymphomas occurring in individuals infected with HIV.-Burkitt lymphomas occurring in each of these settings are histologically identical but differ in some clinical, genotypic, and virologic characteristics.-All forms of Burkitt lymphoma are highly associated with translocations of the MYC gene on chromosome 8 that lead to increased MYC protein levels.-Essentially all endemic Burkitt lymphomas are latently infected with EBV, which is also present in about 25% of HIV-associated tumors and 15% to 20% of sporadic cases.-Characteristic "starry sky" pattern.-When the bone marrow is involved, aspirates reveal tumor cells with slightly clumped nuclear chromatin, two to five distinct nucleoli, and royal blue cytoplasm containing clear cytoplasmic vacuoles.[?]Mantle Cell lymphoma:-Mantle cell lymphoma is an uncommon lymphoid neoplasm that makes up about 2.5% of NHL in the United States and 7% to 9% of NHL in Europe.-It usually presents in the fifth to sixth decades of life and shows a male predominance.-As the name implies, the tumor cells closely resemble the normal mantle zone B cells that surround germinal centers.-Virtually all mantle cell lymphomas have an (11;14) translocation involving the IgH locus on chromosome 14 and the cyclin D1 locus on chromosome 11 that leads to over expression of cyclin D1.-Most common presentation is painless lymphadenopathy.-Symptoms related to involvement of the spleen (present in -50% of cases) and gut are also common. | Pathology | Blood |
