(C) Neural crest # MERKEL CELLS, which are believed to be derived from the neural crest, contain many large (50-100 nm) dense-cored vesicles, presumably containing transmitters, which are concentrated near the junction with the axon. F.S. Merkel referred to these cells as Tastzellen or "touch cells" Merkel cells are found in the skin and some parts of the mucosa (stratum germinativum) of all vertebrates. In mammalian skin, they are clear cells found in the stratum basale (at the bottom of sweat duct ridges) of the epidermis approximately 10 pm in diameter. They also occur in epidermal invaginations of the plantar foot surface called rete ridges. Most often, they are associated with sensory nerve endings, when they are known as Merkel nerve endings (Merkel cell-neurite complex). They are associated with slowly adapting (SA1) somatosensory nerve fibers. They are associated with the sense of light touch discrimination of shapes and textures. They can turn malignant and form the skin tumor known as Merkel cell carcinoma.DERIVATIVES OF NEURAL CRESTDerivative of neural crestDeveloping partsNeurons1.

Patient is showing features suggestive of herpes simplex encephalitis. Clinical manifestations in viral encephalitis includes altered level of consiousness (confusion, behavioral abnormalities), mild lethargy to coma, evidence of both focal or diffuse neurologic signs and symptoms and focal or generalized seizures. Investigations: CSF shows lymphocytic leukocytosis, red blood cells due to hemorrhagic necrosis and elevated cerebrospinal fluid (CSF) protein levels. In HSV encephalitis80% will have abnormalities in temporal lobe and 10% have extra temporal abnormalities. The lesions are typically hyper intense on T2-weighted images. Brain biopsy has been the gold standard for defining HSV encephalitis, but now PCR for detection of HSV DNA in CSF has largely replaced biopsy for defining CNS infection. Acyclovir is used in the treatment. Ref: Harrison's Internal Medicine, 18th Edition, Pages 3421, 3437, Chapters 179, 379, 381.

Nonproliferative diabetic retinopathy usually appears late in the first decade or early in the second decade of the disease and is marked by retinal vascular microaneurysms, blot hemorrhages, and cotton wool spots.> Mild nonproliferative retinopathy progresses to more extensive disease, characterized by changes in venous vessel caliber, intraretinal microvascular abnormalities, and more numerous microaneurysms and hemorrhages. The pathophysiologic mechanisms invoked in nonproliferative retinopathy include loss of retinal pericytes, increased retinal vascular permeability, alterations in retinal blood flow, and abnormal retinal microvasculature, all of which lead to retinal ischemia.

(B) Ageusia # Ageusia is the loss of taste functions of the tongue, particularly the inability to detect sweetness, sourness, bitterness, saltiness, and umami (the taste of monosodium glutamate). It is sometimes confused for anosmia--a loss of the sense of smell. Because the tongue can only indicate texture and differentiate between sweet, sour, bitter, salty, and umami most of what is perceived as the sense of taste is actually derived from smell. True aguesia is relatively rare compared to hypogeusia--a partial loss of taste--and dysgeusia--a distortion or alteration of taste.> Causes of Ageusia:> Neurological damage: Tissue damage to the nerves that support the tongue can cause ageusia, especially damage to the lingual nerve and the glossopharyngeal nerve.> Neurological disorders such as Bell's palsy, Familial dysautonomia, and Multiple sclerosis cause similar problems to nerve dam- age, as do certain infectious conditions like primary amoeboid meningoencephalopathy. The lingual nerve (which is a branch of the trigeminal V3 nerve, but carries taste sensation back to the chorda tympani nerve to the geniculate ganglion of the facial nerve) can also be damaged during otologic surgery, causing a feeling of metal taste.> Problems with the endocrine system:> Deficiency of vitamin B3 (Niacin) and zinc can cause problems with the endocrine system, which may cause taste loss or alteration. Disorders of the endocrine system, such as Cushing's syndrome, hypothyroidism and diabetes mellitus, can cause similar problems.> Ageusia can also be caused by medicinal side-effects from antirheumatic drugs such as penicillamine, antiproliferative drugs such as cisplatin, ACE inhibitors, and other drugs including azelastine, clarithromycin and zopiclone.> Other causes:> Local damage and inflammation that interferes with the taste buds or local nervous system such as that stemming from radiation therapy, glossitis, tobacco abuse, and denture use also cause ageusia. Other known causes include loss of taste sensitivity from aging (causing a difficulty detecting salty or bitter taste), anxiety disorder, cancer, renal failure and liver failure.

Response to Co2, PaCO2 is most impoant factor in control of ventilation under normal conditions. PCo2 is most impoant input regulating magnitude of ventilation under resting conditions. Changes in alveolar ventilation have immediate, pronounced effect on aerial Pco2 (unlike Po2). Even slight alterations from normal Pco2 induce significant reflex. Increased Pco2 increases ventilation. Blood Brain Barrier is permeable to Co2, so increased aerial Pco2 increases brain ECF Pco2 and , it stimulates central chemoreceptors which increases ventilation by stimulating respiratory centers. Regulation of respiration: The rhythmic discharges from the brain that produce spontaneous respiration are regulated by alterations in aerial Po2, PCo2, and H+ concentration. There are numerous factors that affect and control ventilation. Chemical control Co2 ( CSF and brain interstitial fluid H+ concentration) o2 ( carotid and aoic bodies) H+ ( carotid and aoic bodies) Nonchemical control Vagal afferents from receptors in the airways and lungs Afferents from the pons, hypothalamus, and limbic system Afferents from proprioceptors Afferents from baroreceptors: aerial, atrial, ventricular, pulmonary Preipheral (Carotid & Aoic) Chemoreceptors: The carotid bodies are located at the bifurcation of common carotid aery. They send afferents in the carotid sinus nerve to the glossopharyngeal nerve (IX) the aoic bodies are located between the arch of aoa and pulmonary aery afferents ascend in the recurrent laryngeal nerves to the vagus (X). Stimulation results from a decrease in carotid and aoic body tissue PO2. Central Chemoreceptors: situated near (beneath) the ventral surface of the medulla, near the origins of the vagi and glossopharyngeal nerves these are anatomically separate from the respiratory centres, and are bathed in brain ECF. This is impermeable to both H+ and HCO3 -, however CO2 diffuses readily and decreases pH of CSF within a few minutes, which subsequently increases ventilation.

Answer is A (Methaemoglobinemia) Pronounced cyanosis together with chocolate brown colour of 'freshly drawn blood suggests a diagnosis of methaemoglobinemia Methaemoglobinemia * * * Methaemoglobinemia is an uncommon but distinct cause of central cyanosis in the absence of hypoxemia or cardio vascular compromise Methaemoglobinemia occurs when a significant concentration of hemoglobin (Hb) is oxidized to methaemoglobin (Met Hb) When the haem moety (iron atoms) of' Hb molecule encounter a strong oxidizing agent iron loses an electron and switches from the Ferrous (2+) to Ferric (3+) state turning Hb to 'Met Hb' Methaemoglobin has such high oxygen affinity that viually no oxygen is delivered Presentation * * Methaemoglobinemia most commonly presents as cyanosis unresponsive to supplemental oxygen The most notable physical examination finding is generalized cyanosis which can manifest as muddy brown dark mucus membranes before proceding to global skin discolaration 'The charachteristic muddy appearance (chocolate brown) of freshly drawn blood can be a critical clue'-*Blood appears dark brown, brownish, muddy or chocolate in colour immediately after withdrawal. In contrast to normal venous blood, the color does not change with addition of oxygen or agitation in the air'- Diffirential diagnosis in Internal Medicine Methaemoglobinemia > 15% cause symptoms of cerebral ischaemia Methaemoglobinemia > 60% is usually lethal Diagnosis * The hest Methaemoglobinomia is * Methaemoglohin Assay' Treatment * The most effective emergency management for methaemaglobinemia is administration of Methylene bluee which serves as an antidote (intravenous) Methylene blue is not effective in patients with methaemoglobinemia due to Hemoglobinopathy MQ (Haemoglobin M) Methylene blue is contraindicated in patients with G6 PD deficiencyQ since it can cause severe hemolysis due to its potential for oxidation Outline of The Four Main Pathways to MetHb Production 1. Congenitally abnormal hemoglobin: Hemoglobin M Hemoglobin M is passed as an autosomal dominant trait affecting either the alpha or beta chain of hemoglobin; homozygous Hb M affecting both alpha and beta chains is incompatible with life. Amino acid substitution (often a tyrosine for histidine) near the heme iron facilitates iron oxidation. 2. Inherited enzyme deficiencies: NADH-dependent cytochrome b5 -reductase and cytochrome bc deficiency. Deficiency of either cytochrome b5 or its reducing enzyme, cytochrome b5-reductase, decreases reduction of MetHb back to Hb 3. Nitrite (NO2), other oxidants and oxygen-reducing compounds Nitrites are a common oxidizing source of MetHb production. Reducing agents paradoxically produce methemoglobinemia by reducing oxygen to a free radical or water to 1-1,O2, which then oxidizes hemoglobin. 4. "Sensitive" hemoglobin: Blue baby syndrome Bacteria in the immature gastrointestinal tracts of infants conve nitrate (NO3) to the powerful oxidant nitrite (NO,). Infants have a relative NADH-dependent reductase deficiency (only 50% of adult levels) and are more susceptible to oxidative injury.

Ans. D: Instrumentation Instrumentation is by far the most common cause of perforation Boerhaave syndrome/Esophageal perforation, is rupture of the esophageal wall caused by excessive vomiting in eating disorders such as bulimia although it may rarely occur in extremely forceful coughing or other situations, such as obstruction by food. It can cause pneumomediastinum and/or mediastinitis (air or inflammation of the mediastinum) and sepsis. Boerhaave syndrome is a transmural perforation of the esophagus, distinct from Mallory-Weiss syndrome, a nontransmural esophageal tear also associated with vomiting. The term is useful for distinguishing it from iatrogenic perforation, which accounts for 85-90% of cases of esophageal rupture, typically as a complication of an endoscopic procedure, feeding tube, or unrelated surgery. It is associated with "Mackler's triad" which consists of vomiting, lower thoracic pain and subcutaneous emphysema which the later can be heard as Haman's crunch on physical examination. The most common anatomical location of the tear in Boerhaave syndrome is at left posterolateral wall of the lower third of the esophagus, 2-3 cm before the stomach.

C5, C6, C7, C8 and C9 are the factors present in common terminal pathway. The classic activation pathway, mannose-binding lectin activation pathway and alternative activation pathway converge on the final common terminal pathway. The cleavage of C3 by each pathway (classic activation pathway, mannose-binding lectin activation pathway and alternative activation pathway) causes activation of C5, C6, C7, C8 and C9 in the terminal pathway, resulting in the formation of membrane attack complex (MAC) that gets attached to the target cells or bacteria and lyses them.

The complications of IVRA is mainly attributable to the use of the tourniquet. On inflation of the touniquet there is physiological deoxygenation. In patients with sickle cell disease this might lead to sickling crisis. In these patients IVRA causes stasis, local acidosis and hypoxia. Hence IVRA is best avoided in sickle cell disease patients. Adequate oxygenation of the patient would be prudent. Ref: Complications of regional anesthesia By Brendan T. Finucane, Page 216; Essentials of Regional Anesthesia By Alan David Kaye, Richard D.

Sterilization is the most effective contraception to achieve NRR =1 Male sterilization Male sterilization or vasectomy being a comparatively* simple operation can be performed even in primary health centres by trained doctors under local anaesthesia. When carried out under strict aseptic technique, it should have no risk of moality. In vasectomy, it is customary to remove a piece of vas at least 1 cm after clamping. The ends are ligated and then folded back on themselves and sutured into position, so that the cut ends face away from each other. This will reduce the risk of recanalization at a later date. It is impoant to stress that the acceptor is not immediately sterile after the operation, usually until approximately 30 ejaculations have taken place. During this intermediate period, another method of contraception must be used. If properly performed, vasectomies are almost 100 per cent effective. Following vasectomy, sperm production and hormone output are not affected. The sperm produced are destroyed intraluminally by phagocytosis. This is a normal process in the male genital tract, but the rate of destruction is greatly increased after vasectomy. Vasectomy is a simpler, faster and less expensive operation than tubectomy in terms of instruments, hospitalization and doctor's training. Cost-wise, the ratio is about 5 vasectomies to one tubal ligation. Ref: Park 25th edition Pgno : 543

Cocaine causes contraction band necrosis by blocking the reuptake of norepinephrine, resulting in excessive vasoconstriction of coronary vessels, leading to ischemia and infarction of hea tissue. Under these pathological conditions, myocardial cells switch to anaerobic metabolism and therefore glycolysis becomes the sole source of ATP substrate-level phosphorylations by phosphoglycerate kinase and pyruvate kinase. Phosphofructokinase-1 (PFK-1) is the rate-limiting enzyme of glycolysis, and its activity would therefore be increased. Phosphoenolpyruvate carboxykinase is a regulatory enzyme in gluconeogenesis, which is induced by coisol, epinephrine, and glucagon. It functions in the hepatic synthesis of glucose when energy levels from beta-oxidation of fatty acids are adequate. Pyruvate dehydrogenase produces acetyl-CoA from pyruvate and coenzyme A, bridging glycolysis and the Krebs cycle. It requires 5 cofactors, including NAD and FAD, which would no longer be produced by the electron transpo under hypoxic conditions, decreasing its activity. Succinate dehydrogenase is a key enzyme of the Krebs cycle, producing a reduced equivalent of FAD to feed into the electron transpo chain. It is also known as Complex II. The Krebs cycle only functions if oxygen is in appropriate concentrations since it is regulated by the levels of NADH, which is only consumed by the electron transpo chain if there is enough oxygen. The absence of oxygen leads to an accumulation of NADH and a subsequent decrease in the enzyme activities of the Krebs cycle. Ref: Bender D.A., Mayes P.A. (2011). Chapter 20. Gluconeogenesis & the Control of Blood Glucose. In D.A. Bender, K.M. Botham, P.A. Weil, P.J. Kennelly, R.K. Murray, V.W. Rodwell (Eds), Harper's Illustrated Biochemistry, 29e.

Phosphorylation occurs at the hydroxyl groups of serine, threonine, and tyrosine. A protein kinase is a kinase enzyme that modifies other proteins by chemically adding phosphate groups to them (phosphorylation). Phosphorylation usually results in a functional change of the target protein (substrate) by changing enzyme activity, cellular location, or association with other proteins. The chemical activity of a kinase involves transferring a phosphate group from a nucleoside triphosphate (usually ATP) and covalently attaching it to one of three amino acids that have a free hydroxyl group.Most kinases act on both serine and threonine, others act on tyrosine, and a number (dual specificity kinases) act on all three. There are also protein kinases that phosphorylate other amino acids, including histidine kinases that phosphorylate histidine residues.

Laboratory diagnosis of HIV infection Laboratory diagnosis is made by: A. Antibody detection It is the most common method used for diagnosis of HIV infection. ELISA is the most sensitive test and therefore is the screening test of choice. Western blot is the most specific (Confirmatory) test and therefore is the’gold standard’ for diagnosis. Antibodies test usually nucleic acid or antigen. B. Detection of HIV nucleic acid or antigen P24 antigen detection by ELISA can be done 16 days after infection (earlier than antibody detection). Nucleic acid detection tests are the earliest to become positive (12 days after infection), Most commonly used test is reverse transcriptase PCR, (RT-PCR), other methods used are DNA-PCR, RNA-PCR, RNA-bDNA (branched DNA), and RNA-NASBA (nuclei acid sequenced based assay). C. Virus isolation Co-cultivation of the patient’s lymphocyte with uninfected lymphocytes in the presence of IL-2. Not suitable as a routine diagnostic procedure. In infected individual HIV can be isolated from Blood Semen Saliva Urine Lymphocytes Cervical secretions Tears Breast milk

Vasomotor Reversal Of Dale - Adrenaline has biphasic effect on blood pressure. - a1 - Strong receptor thus more effect. - b2 - Sensitive receptor thus stimulated at low dose too. When adrenaline is given IV at high doses 1st BP will increase due to stimulation of a1 > b2 & then BP will decrease due to b2 stimulation. When adrenaline is given IV at high dose with a blocker, exaggerated fall of BP occurs called as Vasomotor Reversal of Dale. In adrenaline producing pheochromocytoma, If person is treated by alpha blocker, then this phenomenon will occur and thus death can occur due to severe hypotension. Therefore alpha blocker is always combined with beta blocker in adrenaline producing tumor.

Nuclear senile cataract: The usual degenerative changes are intensification of the age- related nuclear sclerosis associated with dehydration and compaction of the nucleus resulting in a hard cataract. It is accompanied by a significant increase in water insoluble proteins. However, the total protein content and distribution of cations remain normal. There may or may not be associated deposition of pigment urochrome and/or melanin derived from the amino acids in the lens. The nucleus may become diffusely cloudy (greyish) or tinted (yellow to black) due to deposition of pigments. In practice, the commonly observed pigmented nuclear cataracts are either amber, brown (cataracta brunescens) or black (cataracta nigra) and rarely reddish (cataracta rubra) in colour.
