| single | Jaundice
Jaundice is not a disease but rather a sign that can occur in many different diseases.
Jaundice is the yellowish staining of skin and sclerae which is caused by the high level of blood bilirubin.
On the basis of etiology, jaundice can be divided into 3 types : -
1. Prehepatic jaundice
Prehepatic jaundice is due to increased production of bilirubin which results in an increased bilirubin load presented to the liver.
The liver is normal and is able to conjugate the bilirubin at a normal rate; However, due to overproduction of bilirubin, conjugation capacity of the liver is overwhelmed and unconjugated bilirubin is increased → Unconjugated hyperbilirubinemia.
Prehepatic jaundice is caused by hemolysis, i.e., hemolytic anemia due to any cause, e.g., hereditary spherocytosis, Thalassemia, SCA, Malaria, Drugs (methyldopa, quinine) etc.
2. Hepatic jaundice
Here the cause lies within the hepatocytes which have either a defect in the conjugation process or in the excretion of conjugated bilirubin into the bile.
This type of jaundice is caused by all causes of hepatitis (infection, alcohol, drugs, toxin or autoimmune); in congenital hyperbilirubenemias; and in cirrhosis.
3. Post hepatic (extrahepatic) jaundice
Post hepatic jaundice is due to obstruction of the excretion into the bile, e.g., in stone in CBD, carcinoma pancreas, CBD carcinoma etc.
Conjugation capacity of hepatocytes are normal and they continue their conjugation process without any interference leading to conjugated hyperbilirubinemia. | Pathology | null |

d0d3e944-0e3f-44c1-bb82-39d4c75f93a7 | Which of the following regulates lipolysis in adipocytes? | Activation of fatty acid synthesis mediated by cyclic AMP | Activation of triglyceride lipase as a result of hormone-stimulated increases in cyclic AMP levels | Glycerol phosphorylation to prevent futile esterification of fatty acids | Activation of cyclic AMP production by insulin | 1b
| single | Ans. B. Activation of triglyceride lipase as a result of hormone-stimulated increases in cyclic AMP levelsa. Lipolysis is directly regulated by hormones in adipocytes. Epinephrine stimulates adenylate cyclase to produce cyclic AMP, which in turn stimulates a protein kinase.b. The kinase activates triglyceride lipase by phosphorylating it. Lipolysis then proceeds and results in the release of free fatty acids and glycerol.c. A futile re esterification of free fatty acids is prevented, since adipocytes contain little glycerol kinase to phosphorylate the liberated glycerol, which must be processed in the liver. Inhibition of lipolysis occurs in the presence of insulin, which lowers cyclic AMP levels. Lipoprotein lipase is not an adipocyte enzyme. | Biochemistry | Endocrinology |

Impoant mitochondrial membrane transpoers. 1 = PYT (pyruvate transpoer); 2 = TCT (tricarboxylate transpoer); 3 = ANT (adenine nucleotide transpoer) is dissipated as heat. This is achieved by removal of the proton gradient. (Table 19.5; Fig. 19.17). The uncoupling of oxidative phosphorylation is useful biologically. In hibernating animals and in newborn human infants, the liberation of heat energy is required to maintain body temperature. In Brown adipose tissue, thermogenesis is achieved by this process. Thermogenin, a protein present in the inner mitochondrial membrane of adipocytes, provides an alternate pathway for protons. It is one of the uncoupling proteins (UCP). Thyroxine is also known to act as a physiological uncoupler.Ref: DM Vasudevan Textbook of Medical Biochemistry, 6th edition, page no: 234 | Biochemistry | Respiratory chain |

| single | Cushing's reflex , is a physiological nervous system response to increased intra cranial pressure.Results in cushings triad - increased BP, irregular breathing and bradycardia. Usually seen in terminal stages of head injury . It can also be seen after iv administration of epinephrine. In head injury- CPP=MAP-ICP. CPP- cerebral perfusion pressure. MAP- Mean aerial pressure. ICP- intra cranial pressure Head injury causes increased ICP thus lowering CPP causing ischemia. When ICP approaches the level of mean systemic pressure , cerebral perfusion falls . Bodys response to fall in cerebral perfusion is raise systemic blood pressure and dialate cerebral vessels which increases cerebral blood volume and increases ICP followed by lowering CPP.And causes a vicious cycle. When aerial pressure lowers , a reflex called CNS ischaemic response is initiated by the hypothalamus . Hypothalamus activates sympathetic nervous system causing peripheral vasoconstriction and increased cardiac output. This increases aerial pressure and cerebral blood flow is restored. This response stimulates the baroreceptors in the carotid bodies thus slowing the hea rate drastically- bradycardia(baroreceptor reflex -refer image) 2) Marey's law- Explained by barereceptor reflex States that' hea rate is inversely propoional to blood pressue '(but not the vice versa) .

ALA synthase catalyzes the conversion of succinyl CoA and glycine to delta aminolevulinate. This is the rate limiting enzyme in porphyrin biosynthesis in the mammalian liver. Synthesis of ALA occurs in mitochondria. Last 3 steps of heme synthesis occur in the cytoplasm. The 3 enzymes which catalyse the reactions in cytoplasm are ferrochelatase, protoporphyrinogen oxidase and coproporphyrinogen oxidase. Coproporphyrinogen oxidase catalyze conversion of coproporphyrinogen III to protoporphyrinogen III. Protoporphyrinogen oxidase catalyze conversion of protoporphyrinogen III to protoporphyrin III.

References to the position have been found in some of the oldest known medical documents including versions of the Hippocratic oath. The position is named after the ancient surgical procedure for removing kidney stones, gall stones and bladder stones via the perineum. The position is perhaps most recognizable as the 'often used' position for childbirth: the patient is laid on the back with knees bent, positioned above the hips, and spread apart through the use of stirrups.Obvious benefits from the position is that it provides good visual and physical access to the perineal region. The position is used for procedures ranging from simple pelvic exams to surgeries and procedures involving, but not limited to reproductive organs, urology, and gastrointestinal systems. Used for perianal surgeries like haemorrhoidectomy, fistulectomy, lateral sphinc-terotomy; perineal surgeries like APR & vaginal hysterectomy. | Surgery | Disorders of the Anal Canal |

| single | The common human hookworms are Ancylostoma duodenale and Necator americanus. The larger A duodenale is more pathogenic because it consumes more blood, up to 0.5 mL per worm per day. The adult worms attach with their mouthpas to the mucosa, from which they suck blood. Blood loss is the major sequel of infection which leads to iron-deficiency anemia. Chronic hookworm infection is a common cause of moderate and severe hypochromic microcytic anemia, and heavy infection can cause hypoproteinemia with edema. Chronic hookworm infection in children may lead to growth delay, deficits in cognition, and developmental delay. Ref: Dominguez S.R., Levin M.J. (2012). Chapter 43. Infections: Parasitic & Mycotic.

| single | TYPE II RESPIRATORY FAILUREThis type of respiratory failure is a consequence of alveolar hypoventilation and results from the inability to eliminate carbon dioxide effectively. Mechanisms are categorized by Impaired central nervous system (CNS) drive to breathe (drug overdose, brainstem injury, sleep-disordered breathing, and severe hypothyroidism), Impaired strength with failure of neuromuscular function in the respiratory system. Reduced strength can be due to impaired neuromuscular transmission (e.g., myasthenia gravis, Guillain-Barre syndrome, amyotrophic lateral sclerosis) or respiratory muscle weakness (e.g., myopathy, electrolyte derangements, fatigue).Increased load(s) on the respiratory system. The overall load on the respiratory system can be subclassified into Resistive loads (e.g., bronchospasm), Loads due to reduced lung compliance (e.g., alveolar edema, atelectasis, intrinsic positive end-expiratory pressure --see below), Loads due to reduced chest wall compliance (e.g., pneumothorax, pleural effusion, abdominal distention), and ads due to increased minute ventilation requirements (e.g., pulmonary embolus with increased dead-space fraction, sepsis).Ref: Harrison 19e pg: 1732 | Medicine | Respiratory system |

| multi | Ans: C (Fracture occur through growth plate, metaphysic & epiphysis) SALTER~HARRIS FRACTURES http://wwwlbpt.bridgeport.edu/-gwl/salter-barrisdassification.htmThere are nine types of Salter-Harris fractures; types 1 to V as described by Robert B Salter and W Robert Harris in 1963, and the rarer types V! to IX which have been added subsequently:Type I - A transverse fracture through the growth plate (also referred to as the "physis"): 6% incidenceType II - A fracture through the growth plate and the metaphysis, sparing the epiphysis: 75% incidence, takes approximately 2-3 weeks to heal.Type III - A fracture through growth plate and epiphysis, sparing the metaphysis: 8% incidenceType IV - A fracture tb rough all three elements of the bone, tbegrowth plate, metaphysis, and epiphysis: 10% incidenceType V - A compression fracture of the growth plate (resulting in a decrease in the perceived space between theepiphysis and diaphysis on x-ray): 1% incidenceType VI -Injury to the peripheral portion of the physisand a resultant bony bridge formation which may produce an angular deformity (added in 1969 by Mercer Rang)Type VII - Isolated injury of the epiphyseal plate (VII--IX added in 1982 by JA Ogden)Type VIII - Isolated injury of the metaphysis with possible impairment of endochondral ossificationType IX - Injury of the periosteum which may impair intramem bra nous ossificationThe mnemonic "SALTR" can be used to help remember the first five types: This mnemonic requires the reader to imagine the bones as long bones, with the epiphyses at the base,I - S = Slip (separated or straight across), Fracture of the cartilage of the physis (growth plate)II - A = Above. The fracture lies above the physis, or Away from the joint.III - L = Lower. The fracture is below the physis in the epiphysis.IV - TE = Through Everything. The fracture is through the metaphysis, physis, and epiphysis.V - R = Rammed (crushed). The physis has been crushed, (alternatively SALTER can be used for the first 6 types - as above but adding Type Vr 'E' for Everything or Epiphysis and Type VI'R' for Ring)Fig: Types of Salter-Harris fractures | Orthopaedics | Injuries Around Arm & Elbow |
