Total intravenous anaesthesia refers to a technique in general anaesthesia using a compination of agents given solely by IV route and in the absence of all inhalation agents. TIVA (Total intravenous anaesthesia) is produced by IV propoful. Propofol decreases the cerebral metabolic rate. Propofol does not impair renal function, does not trigger malignant hyperthermia and does not inhibit hypoxic pulmonary vasoconstriction.

Which of the following iodinated compound is present in a maximum concentration in the thyroid?

THYROID HORMONE SYNTHESIS AND SECRETIONThyroid hormones are synthesized in the colloid, near the apical cell membrane of the follicular cells. Catalyzed by the enzyme thyroidal peroxidase, iodide in the thyroid cell is oxidized to iodine.The iodine enters the colloid and is rapidly bound at the 3 position to tyrosine molecules attached to thyroglobulin, forming monoiodotyrosine (MIT).MIT is next iodinated at the 5 position, forming diiodotyrosine (DIT).Two DIT molecules then condense in an oxidative process ("coupling reaction") to form one thyroxine (T4) molecule.Some T3 is probably formed within the thyroid gland by condensation of MIT with DIT. A small amount of reverse T3 (rT3) is also formed.In the normal thyroid, the average distribution of iodinated compounds is 23% MIT, 33% DIT, 35% T4, 7% T3, and 2% reverse T3.

H. capsulatum, a dimorphic fungus, is found in soil heavily contaminated with bird droppings. Which of the following statements best describes the presence of the organism in tissue biopsies?

Histoplasma capsulatum is a dimorphic fungus that forms two types of spores: tuberculate macroconidia and microconidia. Inhalation of the microconidia transmits infection. Inhaled spores (microconidia) are engulfed by macrophages and develop into yeast forms. Most infections remain asymptomatic; small granulomatous foci heal by calcification. However, pneumonia can occur. The heterophile antibody test is useful for early diagnosis of infectious mononucleosis. The figure below illustrates the oval budding yeasts.

Autosomal recessive polycystic kidney disease features include:

Ans. A. Can be diagnosed intrauterineExplanationClinical features of ARPKD (Autosomal recessive polycystic kidney disease) are:Classic ARPKD is generally diagnosed in utero or within the neonatal period and characterized by greatly enlarged echogenic kidneys in diseased fetuses. (Option a)Reduced fetal urine production may contribute to oligohydramnios and pulmonary hypoplasia.About 30% of affected neonates die shortly after birth due to respiratory insufficiency. Close to 60% of mortality occurs within the first month of life.In the classic group, most patients are bom with renal insufficiency and ESRD (End stage renal disease). (Option b)However, infants often have a transient improvement in their GFR; death from renal insufficiency at this stage is rare.Some patients are diagnosed after the neonatal stage and form the older group. Morbidity and mortality in this group often involve systemic hypertension, progressive renal insufficiency, and liver manifestations.The hallmarks of ARPKD liver disease are biliary dysgenesis due to a primary ductal plate malformation with associated periportal fibrosis, namely congenital hepatic fibrosis (CHF) and dilatation of intrahepatic bile ducts (Caroli's disease). CHF and Caroli's disease can then lead to portal hypertension exhibiting hepatosplenomegaly, variceal bleeding, and cholangitis.Some patients with the diagnosis of ARPKD at 1 year of age with nephromegaly exhibit slowly declining renal function over 20 years with only minimally enlarged kidneys at ESRD (Option c and e) and markedly atrophic kidneys following renal transplantation.The slow progression of renal disease is likely due to increasing fibrosis rather than the development of cysts.Systemic hypertension is common in all ARPKD patients, even those with normal renal function. (option d)

Can be diagnosed intrauterine

Proceeds to renal failure till children reaches school going age

Can be palpated abdominally

Hypertension doesn't develop until late stages of the disease

You are the medical officer in charge of the immunisation programme at a sub-centre and you are informed by the local ASHA worker that one of the children who was immunised has has been dizzy. On fuher investigation it was confirmed that the symptoms were due to anxiety of pain of the injection and not as a result of the vaccine. You would consider the incidence as:

The following are the adverse effect following immunisation: Vaccine reaction - Here the event is caused by the inherent propeies of the vaccine when given correctly. Programme error - In this case the event is as a result of error in preparation, handling or administration of the vaccine. Coincidental - The event after immunisation is not caused by the vaccine but by a chance association. Injection reaction - The anxiety of the pain an injection itself may cause hyperventilation, dizziness etc. This is not a result of the vaccine and is called injection reaction.

Inherited hyperammonemia is a result of deficiency of which enzyme of Krebs-Henseleit urea cycle?

Inherited hyperammonemias are a group of six diseases caused by inborn deficiencies of the enzymes of the Krebs-Henseleit urea cycle. The enzymes involved are: 1. N-acetyl glutamate synthetase 2. Arbamyl phosphate synthetase (CPS) 3. Ornithine transcarbamylase (OTC) 4. Argininosuccinic acid synthetase (citrullinemia) 5. Argininosuccinase deficiency 6. Arginase deficiency Most Severe Cases: In the most severe forms of the hyperammonemic disorders, the infants are asymptomatic at bih and during the first day or two of life, after which they refuse their feedings, vomit, and rapidly become inactive and lethargic, soon lapsing into an irreversible coma. Profuse sweating, focal or generalized seizures, rigidity with opisthotonos, hypothermia, and hyperventilation have been observed in the course of the illness. These symptoms constitute a medical emergency, but even with measures to reduce serum ammonia, the disease is usually fatal. Ref: Ropper A.H., Samuels M.A. (2009). Chapter 37.

Lens develops from?

Ans. c (Surface ectoderm). (Ref. Human Embryology by IB Singh, 6th/352)LENS# LENS develops from surface ectoderm.# Compared to the cornea, it has a much lower converging power of 17 diopters because of the relatively similar refractive indices of aqueous humor, lens, and vitreous body (cornea 42 D).# However, the lens is the only part of the refractive apparatus that is adjustable.# Adjustment to near vision (accommodation) therefore involves only the lens.# In addition, the lens functions as a UV filter for wavelengths between 300 and 400 nm and thus has a protective function for the macula.# Notching of the lens = "pseudocoloboma".# Wilson's disease can induce a yellow-green lens discoloration (chalcosis/ sunflower cataract).# Granular gold deposits located under the lens (chrysiasis lends) can occasionally occur after prolonged treatment with gold preparations (e. g. in primary chronic polyarthritis ).# Other medications, e.g., amiodarone or chlorpromazine, are sometimes deposited in the lens.# In patients with cataract, glittering cholesterol crystals are not infrequently found in the lens (so-called Christmas tree/ decoration cataract).

A 49-year-old female taking ibuprofen for increasing joint pain in her hands presents with increasing pain in her midsternal area. Gastroscopy reveals multiple, scattered, punctate hemorrhagic areas in her gastric mucosa. Biopsies from one of these hemorrhagic lesions reveal mucosal erosions with edema and hemorrhage. No mucosal ulceration is seen.

Gastritis is a nonspecific term that describes any inflammation of the gastric mucosa. Acute gastritis refers to the clinical situation of gastric mucosal erosions (not mucosal ulcers). Acute gastritis is also known as hemorrhagic gastritis or acute erosive gastritis. Acute gastritis is associated with the use of nonsteroidal anti-inflammatory drugs, such as aspirin, ibuprofen, and coicosteroids, and also with alcohol, chemotherapy, ischemia, shock, and even severe stress. Two types of stress ulcers are Curling's ulcers, seen in patients with severe burns, and Cushing's ulcers, seen in patients with intracranial lesions. Grossly acute gastritis appears as multiple, scattered, punctate (less than 1 cm) hemorrhagic areas in the gastric mucosa. This is helpful in differentiating acute gastritis from peptic ulcers, which tend to be solitary and larger. Microscopically the gastric mucosa from a patient with acute gastritis is likely to reveal mucosal erosions, scattered neutrophils, edema, and possibly hemorrhage. Acute gastritis. Erosion and complete effacement of the epithelium is observed. The residual glands, on the left, display regenerative changes with basophilic epithelium.

Iliac crest involvement is common in which condition: March 2007

Ans. A: Ankylosing Spondylitis The basic pathologic lesion of ankylosing spondylitis occurs at the entheses, which are sites of attachment to bone of ligaments, tendons, and joint capsules. Enthesopathy results from inflammation, with subsequent calcification and ossification at and around the entheses. Inflammation with cellular infiltration by lymphocytes, plasma cells, and polymorphonuclear leukocytes is associated with erosion and eburnation of the subligamentous bone. The process usually stas at the sacroiliac joints. Other enthesopathic sites include the iliac crest, ischial tuberosity, greater trochanter, patella, and calcaneum. Ankylosing spondylitis/ AS/ Bechterew's disease/ Bechterew syndrome/ Marie Strumpell disease/Spondyloahritis is a chronic, painful, degenerative inflammatory ahritis primarily affecting spine and sacroiliac joints, causing eventual fusion of the spine. AS is a systemic rheumatic disease and one of the seronegative spondyloahropathies. About 90% of the patients express the HLA-B27 genotype. Men are affected more than women by a ratio in excess of 10:1. Typical signs of progressed AS are the visible formation of syndesmophytes on X-rays and abnormal bone outgrowths similar to osteophytes affecting the spine. Complete fusion results in a complete rigidity of the spine, a condition known as bamboo spine. In 40% of cases, ankylosing spondylitis is associated with iridocyclitis causing eye pain and photophobia. 4.1 AS is also associated with ulcerative colitis, Crohn's disease, psoriasis, and Reiter's disease Other complications are aoic regurgitation, Achilles tendinitis, AV node block and amyloidosis & restrictive lung disease. A clinical examination and X-ray studies of the spine, which show characteristic spinal changes and sacroiliitis, are the major diagnostic tools. The Schober's test is a useful clinical measure of flexion of the lumbar spine performed during examination.

The number of ATPs generated in krebs cycleare ?

Ans. is 'b' > b' i.e., 24 One turn of the TCA cycle, staing with acetyl CoA produces 10 ATPs. When the staing molecule is pyruvate, the oxidative decarboxylation of pyruvate, the oxidative decarboxylation of pyruvate yields 2.5 ATPs and therefore, 12.5 ATPs are produced when staing compound is pyruvate. Since, two molecules of pyruvate enter the TCA cycle when glucose is metabolized (glycolysis produces 2 molecules of pyruvate), the number of ATPs is doubled. Therefore, 25 ATP molecules, per glucose molecule, are produced when pyruvate enters the TCA cycle.Note : Previously calculations were made assuming that NADH produces 3 ATPs and FADH generates 2 ATPs. This will amount a net generation of 30 ATP molecules in TCA per molecule glucose and total 38 molecules from staing. Recent experiments show that these values are overestimates and NADH produces 2.5 ATPs and FADH produces 1.5 ATPs. Therefore, net generation during TCA is 25 ATPs and complete oxidation of glucose through glycolysis plus citric acid cycle yield a net 32 ATPs.Energy yield (number of ATP generated) per molecule of glucose when it is completely oxidized through glycolysis plus citric acid cycle, under aerobic conditions, is as follows :- Method ofNo of ATPsNo of ATPsPathwayStepEnzymeSource ATP formationgained perglucose(new calculation)As per oldcalculationGlycolysis1Hexokinase MinusMinus 1Do3Phosphofructokinase MinusMinus 1Do5Glyceraldehyde-3-p DHNADH Respiratory chain2.5 x 2 = 53 x 2 = 6Do61,3-BPGkinase ATPSubstrate level1 x 2 -- 21 x 2 = 2Do9Pyruvate kinaseATP Substrate level1 x 2 = 21 x 2 = 2Pyruvate to?PyruvateNADH Respiratory chain2.5x2= 53x2= 6Acetyl CoA Dehydrogenase TCA cycle3Isocitrate DHNADH Respiratory chain2.5x2= 53 x 2= 6Do4Alpha keto glutarate DHNADH Respiratory chain2.5x2= 53x2= 6Do5Succinate thiokinaseGTP Substrate level1 x 2 = 21 x 2 = 2Do6Succicinate DHFADH2Respiratory chain1.5x2= 32 x 2= 4Do8Malate DHNADH Respiratory chain2.5x2= 53 x 2= 6Net generation in glycolytic pathway 9 minus 2= 7 10 minus 2= 8Generation in pyruvate dehydrogenase reaction 5 * 6Generation in citric acid cycle 20 * 24Net generation of ATP from one glucose mole 32 * 38

A female child with virilization, hypertension with low plasma renin diagnosis is :

9] Congenital adrenal hyperplasia represents a group of autosomal recessive inherited, metabolic errors, each characterized by decency or total lack of a particular enzyme involved in the biosynthesis of cortical steroids, Steroidogenesis is then channelled into other pathways leading to increased production of androgens, which accounts for virilization. Simultaneously, the decency of cortisol results in increased secretion of ACTH resulting in adrenal hyperplasia. Following enzymes are implicated in the congenital adrenal hyperplasia 21 α hydroxylase decency (partial or complete) 17 α hydroxylase deficiency 11β hydroxylase deficiency 21 α hydroxylase deficiency • Two forms of this deficiency include - A. Salt-wasting adrenogenital ism B. Simple Virilizing adrenogenital ism A) Salt-wasting syndrome (complete lack) The salt wasting syndrome results from complete lack of 21 hydroxylases. There is no synthesis of mineralocorticoids and glucocorticoids in the adrenal cortex. Decreased mineralocorticoids causes marked sodium loss in the urine, resulting in hyponatremia, hyperkalemia, acidosis and hypotension. Because of the enzyme block, there is increased formation of 17 - hydroxyprogesterone, which is then shunted into the production of testosterone. This may cause virilism (pseudo-hermaphroditism) in female infants. That is (XX) Female with 21 hydroxylase deficiency develops ovaries, female ductal structures and external male genitalia. But in the male child, the effect of increased testosterone will not be manifested at the time of birth. The complete21 hydroxylase deficiency or salt wasting syndrome usually comes to light only after the birth because in utero the electrolytes and uids can be maintained by maternal kidneys. Males with this disorder comes to clinical attention 5 to 15 days later because of salt losing crisis while females come to attention soon after the birth because of the virilization. B) Simple Virilizing adrenogenital syndrome (Partial deficiency) Occurs in individuals with partial deficiency of 21 hydroxylases Less severe deficiency of mineralocorticoid, is sufficient for salt reabsorption, but the lowered glucocorticoid fails to cause feedback inhibition of ACTH secretion. Thus level of aldosterone is mildly reduced, testosterone is increased and ACTH elevated with resultant adrenal hyperplasia. 11B hydroxylase deficiency-. Rare Leads to decreased cortisol and increased ACTH. This, in turn, leads to the accumulation of DOC (deoxycorticosterone) and 11 deoxycortisol both of which are strong mineralocorticoids. This results in increased sodium retention by the kidneys and hypertension, hypokalemia. Patients also develop virilization due to androgen excess. 17 α hydroxylase deficiency - Patients with deficiency of 17 hydroxylases also have impaired cortisol production, increased ACTH and secondary increased DOC. These patients, however, cannot synthesize normal amount of androgens and estrogens. This is because the gene that codes for 17 α hydroxylase is the same for the enzyme in the adrenal cortex and the gonads and the decency is same in both organs. Because of decreased sex hormones, genotypic females develop primary amenorrhoea and fail to develop secondary sex characteristics while genotypic males will present as pseudohermaphrodite. 3 β hydroxylase deficiency 3-β hydroxylase deficiency is a rare genetic disorder of steroid biosynthesis that results in decreased production of all three groups of adrenal steroids which include mineralocorticoid, glucocorticoid and sex steroids. Decreased mineralocorticoid secretion results in varying degrees of salt wasting in both males and females. Decent androgen production results in ambiguous genitalia in males The usual presentation is a male child with ambiguous genitalia and severe salt wasting. Sometimes it may also occur in females

Ans. is 'b' ie pressure abrasion (Ref: Parikh; 6/e, p4.3).An abrasion is a superficial injury involving only the superficial layers of the skin (epidermis only), caused by friction and / or pressure between the skin and some rough object or surface. It bleeds very slightly, heals rapidly in a few days and leaves no scar.They can be classified into 3 types, depending on the manner they are created.ScratchIs a linear injury produced by a sharp object, such as pin, thorn or finger nail.Graze (Sliding, scraping or grinding abrasion).Is produced when a broad surface of skin slides against a rough surface.It is also known as brush or friction burn because it is caused by the frictional force and resembles a burn after dryingIt is commonly found in road traffic accidents.Imprint, Pressure or contact abrasion.Is produced as a result of direct impact or pressure of or contact with some object at right angles to the skin surface.The cuticle is crushed, and the object marks a reproduction of its shape and pattern on the to the skin, therefore it is known as patterned abrasion.Example are ligature marks in hanging and strangulation, nail and thumbs marks in throttling, teeth marks in biting, radiator, grill or tyre mask in vehicular accidents.

The duct runs forwards for a sho distance between the buccinator and the oral mucosa. Finally, the duct turns medically and opens into the vestibule of the mouth(gingivobuccal vestibule)opposite the crown of the upper second molar tooth. Notes: Parotid abscess may be caused by spread of infection from the opening of parotid duct in the mouth cavity. <img src=" /> REF.BDC VOL.3,Sixth edition pg 110

All the teeth in patient’s mouth are similarly affected as shown in the radiograph. What is the most likely anomaly?

Dentinal dysplasia Dentinal dysplasia is an inherited condition affecting both dentitions. It is divided into two types: Type I (radicular dentinal dysplasia) and Type II (coronal dentinal dysplasia). It occurs less frequently than dentinogenesis imperfecta. Clinical features Type I is the more frequent type. Teeth erupt normally with no obvious abnormality but rapidly develop mobility resulting from limited root support. In type II, the deciduous teeth are similar to those in dentinogenesis imperfecta, whereas the permanent teeth appear normal. Radiological signs In Type I, all the teeth, except the canines, have extremely short roots. The roots are conical or blunted. There is pulpal obliteration and the inferior aspects of the crown exhibit linear crescent-shaped radiolucent lines. Periapical radiolucencies are commonly seen associated with non-carious teeth in Type I dentinal dysplasia. In Type II dentinal dysplasia, obliteration of the pulp occurs post eruption in the deciduous dentition. In the permanent dentition, there is alteration in the configuration of the pulp resulting in enlarged pulp chambers extending well down into the root. The pulp contains multiple calcifications.

Middle aged female with mass in sella turcica hormone increased is -

The sella turcica is a saddle shaped depression of the sphenoid bone. It forms the caudal border of the pituitary gland. Sella turcica is an anatomically complex area with a number of different potential pathologies especially neoplastic process. Pathologies of sella turcica can lead to important clinical presentations such as hormonal imbalances from pathologies affecting the pituitary gland and neurological symptoms from the mass effect. Sella turcica is critically located as several structures pass close to it due to compression of the adjacent structures.

All will predispose to atherosclerosis, except

Elevated plasma levels of  homocysteine are associated with increased risk of atherosclerosis, thrombosis and hypertension. Lipoprotein A inhibits fibrinolysis, therefore predisposes to atherosclerosis. Atherosclerosis (Greek  athere-mush)  is a complex disease characterized by thickening or hardening of arteries due to the accumulation of lipids (particularly cholesterol, free, and esterified), collagen, fibrous tissue, proteoglycans, calcium deposits, etc. in the inner arterial wall.  Satyanarayana, Ed 3, Pg No 152

Most serious complication seen in other eye after traumatic injury to one eye: March 2005, September 2008

Ans. C: Sympathetic ophthalmia Sympathetic ophthalmia (SO) is a condition in which serious inflammation attacks the sound eye after injury (including intraocular surgeries) to the other. It is the most dreaded complication of unilateral severe eye injury, as it can leave the patient completely blind. Symptoms may develop from days to several years after a penetrating eye injury. Sympathetic ophthalmia is thought to be an autoimmune inflammatory response toward ocular antigens, specifically a delayed hypersensitivity to melanin-containing structures from the outer segments of the photoreceptor layer of the retina. It is thought that Louis Braille, who injured his left eye as a child, lost vision in his right eye due to SO Floating spots and loss of accommodation are among the earliest symptoms. The disease may progress to severe iridocyclitis with pain and photophobia. Commonly the eye remains relatively painless while the inflammatory disease spreads through the uvea. The retina, however, usually remains uninvolved. Papilledema, secondary glaucoma, vitiligo and poliosis of the eyelashes may accompany SO. Diagnosis is clinical, seeking a history of eye injury. An impoant differential diagnosis is Vogt-Koyanagi-Harada syndrome (VKH), which is thought to have the same pathogenesis, without a history of surgery or penetrating eye injury. Definitive prevention of SO requires prompt (within the first 7 to 10 days following injury) enucleation of the injured eye. Evisceration--the removal of the contents of the globe while leaving the sclera and extraocular muscles intact--is easier to perform, offers long-term orbital stability, and is more aesthetically pleasing. But evisceration may lead to a higher incidence of SO compared to enucleation. Immunosuppressive therapy is the mainstay of treatment for SO. When initiated promptly following injury, it is effective in controlling the inflammation and improving the prognosis.
