| single | Ans: A (Fatty streaks) Ref: Robbins Pathologic Basis of Disease, 8th edition.Explanation:Fatty streaks are the earliest lesions in atherosclerosis " Ref: RobbinsMorphology of AtherosclerosisFatty StreaksThese are the earliest lesions in atherosclerosis.They are composed of lipid-filled foamy macrophages.Beginning as multiple minute flat yellow spots, they eventually coalesce into elongated streaks 1 cm or more in length.These lesions are not significantly raised and do not cause any flow disturbanceAortas of infants less than 1 year old can exhibit fatty streaks, and such lesions are seen in virtually all children older than 10 years, regardless of geography, race, sex, or environment.The relationship of fatty streaks to atherosclerotic plaques is uncertainThey may evolve into precursors of plaques, not all fatty streaks are destined to become advanced lesions.Atherosclerotic PlaqueThe key processes in atherosclerosis are intimal thickening and lipid accumulationAtheromatous plaques impinge on the lumen of the artery and grossly appear white to yellow: superimposed thrombus over ulcerated plaques is red-brown.Plaques vary from 0.3 to 1.5 cm in diameter but can coalesce to form larger massesAtherosclerotic lesions are patchy, on cross- section, the lesions appear "eccentric"Local flow disturbances (e.g., turbulence at branch points) leads to increased susceptibility to plaque formation.In descending order, the most extensively involved vessels are theLower abdominal aorta (MC)The coronary arteries (Second MC)The popliteal arteriesThe internal carotid arteriesVessels of the circle of WillisVessels of the upper extremities are usually spared, as are the mesenteric and renal arteries, except at their ostia.Atherosclerotic plaques have three principal components:Cells, including smooth muscle cells, macrophages, and T cellsECM, including collagen, elastic fibers, and proteoglycansIntracellular and extracellular lipidSuperficial fibrous cap composed of smooth muscle cells and dense collagen.Beneath and to the side of the cap (the "shoulder") is a more cellular area containing macrophages, T cells, and smooth muscle cells.Deep to the fibrous cap is a necrotic core, containing lipid (primarily cholesterol and cholesterol esters), debris from dead cells, foam cells (lipid-laden macrophages and smooth muscle cells), fibrin, variably organized thrombus, and other plasma proteins and cholesterolThe periphery of the lesions show neovascularization (proliferating small blood vessels;Plaques generally continue to change and progressively enlarge due to cell death and degeneration, synthesis and degradation (remodeling) of ECM, and organization of thrombus.Atheromas often undergo calcificationAtherosclerotic plaques are susceptible to the following clinically important changes* Rupture, ulceration, or erosion of the intimal surface of atheromatous plaques exposes the blood to highly thrombogenic substances and induces thrombosis.* Such thrombosis can partially or completely occlude the lumen and lead to downstream ischemia.* If the patient survives the initial thrombotic occlusion, the clot may become organized and incorporated into the growing plaque.* Hemorrhage into a plaque. Rupture of the overlying fibrous cap, or of the thin-walled vessels in the areas of neovascularization, can cause intra-plaque hemorrhage; a contained hematoma may expand the plaque or induce plaque rupture.* Atheroembolism. Plaque rupture can discharge atherosclerotic debris into the bloodstream, producing microemboli* Alienism formation. Atherosclerosis-induced pressure or ischemic atrophy of the underlying media, with loss of elastic tissue, causes weakness resulting in aneurysmal dilation and potential rupture. | Pathology | Atherosclerosis and Arteriosclerosis |

| single | When LDH-1 is greater than LDH-2, it is referred to as flipped LDH and is indicative of MI. LDH-1 isoenzyme is found primarily in hea muscle and is lesser in concentration than the LDH-2 Isoenzyme which is primarily found in RBC. When the concentration of LDH-1 is observed to be greater than LDH2. It is referred to as flipped LDH and is indicative of Myocardial infarction. LDH has five isoenzymes: LDH-1 LDH-1 is found primarily in hea muscle 17% to 27% LDH-2 LDH-2 is primarily found in Red blood cells 27% to 37% LDH-3 LDH-3 is highest in the lung 18% to 25% LDH-4 LDH-4 is highest in the kidney, placenta, and pancreas 3% to 8% LDH-5 LDH-5 is highest in the liver and skeletal muscle 0% to 5% The LDH test helps determine the location of tissue damage. Thus in Normal ratios LDH-1 is less than LDH-2 and LDH-5 is less than LDH-4. When LDH-1 is greater than LDH-2: It is referred to as flipped LDH. It is indicative of MI. When your LDH-5 is greater than your LDH-4: It could mean damage to the liver or liver disease. This includes cirrhosis and hepatitis. Ref: Harrisons 19th edition | Medicine | C.V.S |

| single | Functions: Transpo Systems An essential role of biomembranes is to allow movement of all compounds necessary for the normal function of a cell across the membrane barrier. These compounds include a vast array of substances like sugars, amino acids, fatty acids, steroids, cations and anions to mention a few. These compounds must enter or leave the cells in an orderly manner for normal functioning of the cell. A. 1. Ion Channels Ion channels are transmembrane channels, pore-like structures composed of proteins. Specific channels for Na+, K+, Ca++, and Cl- have been identified. Cation conductive channels are negatively charged within the channel and have an average diameter of about 5 to 8 nm. All ion channels are basically made up of transmembrane subunits that come together to form a central pore through which ions pass selectively. All channels have gates and are controlled by opening and closing. Types of Gates Two types of gated channels. They are a. Ligand-gated channels: In this, a specific molecule binds to a receptor and opens the channel. Example: Acetylcholine receptor is present in the postsynaptic membrane. It is a complex of five subunits, having a binding site for acetylcholine. Acetylcholine released from the presynaptic region binds with the binding site of the postsynaptic region, which triggers the opening of the channel and influx of Na+. b. Voltage-gated channels: These channels open or close in response to changes in membrane potential. Some propeies of ion channels * Composed of transmembrane protein subunits. * Highly selective. * Well regulated by the presence of "gates". * Two main types of gates: Ligand-gated and voltage-gated. * Activities are affected by ceain drugs. * Mutations of genes encoding transmembrane proteins can cause specific diseases. 2. Ionophores Ceain microorganisms can synthesize small organic molecules, called ionophores, which function as shuttles for the movement of ions across the membrane. Structure: These ionophores contain hydrophilic centres that bind specific ions and are surrounded by peripheral hydrophobic regions. Types: Two types: (a) Mobile ion carriers: Like valinomycin (Refer uncouplers of oxidative phosphorylation). (b) Channel formers: Like gramicidin. 3. Water Channels (Aquaporins) In ceain cells, e.g. in red blood cells, and cells of the collecting ductules of the kidney, the movement of water by simple diffusion is enhanced by movements of water through water channels, composed of tetrameric transmembrane proteins called aquaporins. About five distinct types of aquaporins have been recognised. CLINICAL ASPECT Recently mutations in the gene encoding AP-2 (Aquaporin 2) protein, have been shown to be the cause of one type of nephrogenic diabetes insipidus. 4. Gap Junction Ceain cells develop specialized regions on their membranes for intercellular communications which are in close proximity. Function: They mediate and regulate the passage of ions and small molecules upto 1000 to 2000 mol wt, through a narrow hydrophilic core connecting the cytosol of adjacent cells. Structure: They are primarily composed of protein, called connexon which contains four membrane-spanning a-helices. the mitochondrial membrane also has paicularly energy coupling mechanism.Ref: MN Chatterjea Textbook of Medical Biochemistry, 8th edition | Biochemistry | Respiratory chain |
963aee66-8c6e-46da-ae29-8b9d67cdad80 | Burst supression pattern on EEG is typically seen in: | Anoxic encephalopathy | Absence seizures | SSPE | Herpes simplex encephalitis | 0a
| multi | Ref: Ref: Harrisons 18/e p e-45 chapter
As the depth of coma increases, the EEG becomes nonreactive and may show a burst-suppression pattern, with bursts of mixed-frequency activity separated by intervals of relative cerebral inactivity. In other instances there is a reduction in amplitude of the EEG until eventually activity cannot be detected. Such electrocerebral silence does not necessarily reflect irreversible brain damage, because it may occur in hypothermic patients or with drug overdose.
The prognosis of electrocerebral silence, when recorded using an adequate technique, depends upon the clinical context in which it is found. In patients with severe cerebral anoxia, for example, electrocerebral silence in a technically satisfactory record implies that useful cognitive recovery will not occur. | Unknown | null |

| single | Hypeension due to an occlusive lesion of a renal aery is renovascular hypeensionIn the initial stages, the mechanism of hypeension generally is related to activation of the renin-angiotensin system. Obstruction of the renal aery leads to decreased renal perfusion pressure, thereby stimulating renin secretion. Over time, possibly as a consequence of secondary renal damage, this form of hypeension may become less renin-dependent.As a screening test, renal blood flow may be evaluated with a radionuclide -ohoiodohippurate (OIH) scan, or glomerular filtration rate may be evaluated with a - diethylenetriamine pentaacetic acid (DTPA) scan before and after a single dose of captopril (or another ACE inhibitor).Contrast aeriography remains the "gold standard" for evaluation and identification of renal aery lesions.Harrison 19e pg: 1618 | Medicine | All India exam |

97680640-ea40-4384-bdfb-b6ae47417707 | A 63 year old man presents with a triad of angina, syncope and congestive hea failure. Which of the following valvular hea lesion can be suspected- | antral stenosis | Tricuspid regurgitation | Aoic stenosis | Aoic regurgitation | 2c
| single | Even severe AS may exist for many years without producing any symptoms because of the ability of the hyperophied LV to generate the elevated intraventricular pressures required to maintain a normal stroke volume. Most patients with pure or predominant AS have gradually increasing obstruction over years, but do not become symptomatic until the sixth to eighth decades. Exeional dyspnea, angina pectoris, and syncope are the three cardinal symptoms. Dyspnea results primarily from elevation of the pulmonary capillary pressure caused by elevations of LV diastolic pressures secondary to reduced left ventricular compliance and impaired relaxation. Angina pectoris usually develops somewhat later and reflects an imbalance between the augmented myocardial oxygen requirements and reduced oxygen availability. Exeional syncope may result from a decline in aerial pressure caused by vasodilation in the exercising muscles and inadequate vasoconstriction in nonexercising muscles in the face of a fixed CO, or from a sudden fall in CO produced by an arrhythmia.

| single | Ref:Robbins Basic Pathology (9th Edition),page no.478,479 Sarcoidosis Although sarcoidosis is considered here as an example of a restrictive lung disease, it is impoant to note that sarcoidosis is a multisystem disease of unknown etiology characterized by noncaseating granulomas in many tissues and organs. MORPHOLOGY The diagnostic histopathologic feature of sarcoidosis is the noncaseating epithelioid granuloma, irrespective of the organ involved. This is a discrete, compact collection of epithelioid cells rimmed by an outer zone of largely CD4+ T cells. The epithelioid cells are derived from macrophages and are characterized by abundant eosinophilic cytoplasm and vesicular nuclei. It is not uncommon to see intermixed multinucleate giant cells formed by fusion of macrophages. A thin layer of laminated fibroblasts is present peripheral to the granuloma; over time, these proliferate and lay down collagen that replaces the entire granuloma with a hyalinized scar. Two other microscopic features are sometimes seen in the granulomas: (1) Schaumann bodies, laminated concretions composed of calcium and proteins; and (2) asteroid bodies, stellate inclusions enclosed within giant cells. Their presence is not required for diagnosis of sarcoidosis--they also may occur in granulomas of other origins. Rarely, foci of central necrosis may be present in sarcoid granulomas, suggesting an infectious process. Caseation necrosis typical of tuberculosis is absent The lungs are involved at some stage of the disease in 90% of patients. The granulomas predominantly involve the interstitium rather than air spaces, with some tendency to localize in the connective tissue around bronchioles and pulmonary venules and in the pleura ("lymphangitic" distribution). The bronchoalveolar lavage fluid contains abundant CD4+ T cells. In 5% to 15% of patients, the granulomas eventually are replaced by diffuse interstitial fibrosis, resulting in a so-called honeycomb lung. Intrathoracic hilar and paratracheal lymph nodes are enlarged and calcification in 75% to 90% of patients, while a third present with peripheral lymphadenopathy. The nodes are characteristically painless and have a firm, rubbery texture. Unlike in tuberculosis, lymph nodes in sarcoidosis are "nonmatted" (nonadherent) and do not ulcerate. | Pathology | Respiratory system |

Ridges - Linear elevations.Supraventricular crest - a ridge present between the pulmonary and atrioventricular orifices, extends downwards in the posterior wall of the infundibulum.2. Bridges -'Muscular elevations with fixed ends on ventricular walls, the center being free.Septomarginal trabecula: It is a specialized bridge which extends from the right of ventricularseptum to the base of anterior papillary muscle. It contains the right branch of atrioventricular bundle.3. Papillary muscles are conical projections of muscle fiber bundles. Their base is attached to the ventricular wall and the apex is attached to the chordae tendinae, which are further attached to the cusps of atrioventricular (AV) valves. There are three papillary muscles in the right and two in the left ventricle. They regulate closure of atrioventricular valves.ii) Smooth outflowing part (infundibulum or conus arteriosus)# Smooth outflowing part develops from mid portion of bulbus cordis and surrounds pulmonary valveSupraventricular crest (crista supraventriculars) or infundibuloventricular crest separates tricuspid (AV) orifice and pulmonary orifice, i.e. inlet and outlet parts. | Anatomy | Thorax |
