Cimetidine inhibits cytochrome P450 and reduces hepatic blood flow. As a result it inhibits the metabolism of OCP's and enhance their blood levels and increases their effectiveness. Phenytoin and Griseofulvin induces cytochrome P450 enzymes and thereby enhance the metabolism of oral contraceptive pills. Ampicillin suppresses the intestinal flora and decreases enterohepatic circulation of OCP. Ref: Essentials of Medical Pharmacology By K D Tripathi, 5th Edition, Page 590

A patient with carbon monoxide poisoning is treated with hyperbaric oxygen that increases the aerial PO2 to 2000 mm Hg. The amount of oxygen dissolved in the aerial blood (in ml/100 ml) is:
|
Since the solubility of oxygen is 0.003 ml O2/100 ml blood, an aerial PO2 of 2000 mm Hg will increase the concentration of the dissolved oxygen to 6 ml O2/100 ml blood. Note that this actually exceeds the normal aerial-venous difference for the oxygen concentration.

Unlike sterilization, disinfection is not sporicidal (does not kill spores). Decontamination The process of rendering of an aicle or area free of danger from contaminants, including microbial, chemical, radioactive and other hazards. Antisepsis It is defined as" Prevention of infection, usually by inhibiting the growth of bacteria in wound or tissues". Antiseptics Chemical disinfectants which can be safely applied to skin or mucous membrane are called antiseptics or skin disinfactant. Best and most commonly used antiseptic is povidone iodine (betadine). Commonly used skin disinfactants for hand washing are povidone iodine (betadine), chlorhexidine and isopropyl alcohol. Disinfectants Antimicrobials applied only to inanimate object. They are not used for surface disinfection(A"9) (skin or mucous membrane). Germicides These include both antiseptics and disinfectant.

It is increased(hypersthenuria) in diabetes mellitus, in nephrosis and in excessive perspiration. In chronic renal failure, the specific gravity of urine is low and fixed at 1.010 (isosthenuria). The earliest manifestation of renal damage may be the inability to produce concentrated urine. Reference : page 317-18 Textbook of Biochemistry D M Vasudevan 6th edition

Initial treatment for perforated corneal ulcer is:March 2009
|
Ans. B: Tissue adhesive glueBacterial corneal ulcer requires intensive foified antibiotic therapy to treat the infection.Fungal corneal ulcers require intensive application of topical anti-fungal agents.Viral corneal ulceration caused by herpes virus may respond to antivirals like topical acyclovir ointment instilled at least five times a day.Alongside, suppoive therapy like pain medications are given, including topical cycloplegics like atropine or homatropine to dilate the pupil and thereby stop spasms of the ciliary muscle.All forced expiration like blowing the nose, coughing etc. must be avoided.Proper nutrition, including protein intake and Vitamin C are usually advised.In cases of Keratomalacia, where the corneal ulceration is due to a deficiency of Vitamin A, supplementation of the Vitamin A by oral or intramuscular route is given.Drugs that are usually contraindicated in corneal ulcer are topical coicosteroids and anesthetics - these should not be used on any type of corneal ulcer because they prevent healing, may lead to superinfection with fungi and other bacteria Fuher option is the use of a tissue adhesive such as N-butyl 2-ethyl cyanoacrylate monomer which is applied to the area of perforation after careful debridement. Drying of the adhesive may take few minutes after which anterior chamber may reform.Following this, a continuous-wear soft contact lens can be applied or a definite surgical procedure such as therapeutic penetrating keratoplasty or conjunctival flap undeaken.Superficial ulcers may heal in less than a week.

Normal bud ends in trigone and there is no reflux, but in the lower bud which drains the lower pole of kidney will end more laterally in the bladder via a submucosal tunnel and will usually have vesicoureteric reflux.* If detected in children VUR is common, if detected in adults usually have no symptoms.* Reflux of urine from one ureter to other ureter instead of flowing distally is known as "Yoyo reflex" and is seen in such types of duplicated ureters and renal pelvis.

Umami taste sensation is due to-
|
Ans. is 'b' i.e., Glutamic acid o The umami taste is the fifth taste which is unique. The proposed mechanism of umami taste is through glutamate taste sensors (glutamate receptors) with release of neuronal glutamic acid.o Umami taste sensation is the most recent one, discovered in early 1900s.Taste sensationso There are four basic tastes namely Sweet, bitter, Salty and Sour. There mechanisms of sensory transduction are : o There are different mechanisms of sensory transduction.1) Sweet receptor is a Gprotein coupled receptor and leads to an increase in cAMP concentration in the sensory cells which results in closure of K+ channels and depolarization.2) Bitter receptors are also G protein coupled receptors and causes rise in intracellular Ca+2 by IP3-DAG system. Rise in intracellular Ca+2 triggers neurotransmitter release.3) Salty-tasti ttg substances depolarize taste cells by activating amiloride-sensitive Na+ channels.4) Sour-tasting substances depolarize taste cells by raising the intracellular //+ ion concentration, which causes closure of K+ channels.o The umami taste is the fifth taste which is unique. The proposed mechanism of umami taste is through glutamate taste sensors (glutamate receptors) with release of neuronal glutamic acid.

Surgery for advanced, non-resectable pancreatic adenocarcinoma can palliate obstruction of CBD or duodenum, as well as control visceral pain.
Hepaticojejunostomy, choledochojejunostomy or choledochoduodenostomy offers durable drainage of an obstructed bile duct.
Cholecystojejunostomy is less reliable but can be employed when tumor bulk precludes common duct procedure.
Gastrojejunostomy (antecolic anastomosis) palliates gastric outlet obstruction.
Antecolic anastomosis is done to avoid complications from an expanding lesser sac tumor.

They can be of two types-Dysostoses or Dysplasias.'-Robbins 8/e p1210 Developmental anomalies resulting from localized problems in the migration of mesenchymal cells and their formation of condensations are known as dysostoses. They are usually limited to defined embryologic structures and may result from mutations in ceain transcription factors (Homeobox genes). Mutations in the regulators of skeletal organogenesis, such as cellular signaling mechanisms (e.g., growth factors and their receptors), and matrix components (e.g., types 1 and 2 collagen), affect cailage and bone tissues globally, and these disorders are known as dysplasias.-

A 30year old male with past history of otitis media and mastoiditis presented with severe throbbing headache , high grade fever ,nausea, vomiting, confusion, gait disturbance. On examination he was febrile, ataxic with nystagmus and there was no neck rigidity. Mri brain with contrast revealed a brain abscess. Which of the following is likely site of brain abscess?
|
Approximately one-third of brain abscesses are associated with otitis media and mastoiditis, often with an associated cholesteatoma. Otogenic abscesses occur predominantly in the temporal lobe (55-75%) and cerebellum (20-30%). In some series, up to 90% of cerebellar abscesses are otogenic. The clinical presentation of a brain abscess depends on its location, the nature of the primary infection if present, and the level of the ICP. Hemiparesis is the most common localizing sign of a frontal lobe abscess. A temporal lobe abscess may present with a disturbance of language (dysphasia) or an upper homonymous quadrantanopia. Nystagmus and ataxia are signs of a cerebellar abscess. Signs of raised ICP--papilledema, nausea and vomiting, and drowsiness or confusion--can be the dominant presentation of some abscesses, paicularly those in the cerebellum. Meningismus is not present unless the abscess has ruptured into the ventricle or the infection has spread to the subarachnoid space. Ref Harrison 20th edition page 1013,1014.

Ans:C.)Antecubital Fossa. Atopic dermatitis It is a chronic, pruritic inflammatory skin disease (see image below) of unknown origin that usually stas in early infancy, but also affects a substantial number of adults. AD is commonly associated with elevated levels of immunoglobulin E (IgE). That it is the first disease to present in a series of allergic diseases--including food allergy, asthma, and allergic rhinitis, in order--has given rise to the "atopic march" theory. The earliest lesions affect the creases (antecubital and popliteal fossae), with erythema and exudation. Over the following few weeks, lesions usually localize to the cheeks, the forehead and scalp, and the extensors of the lower legs; however, they may occur in any location on the body, usually sparing the diaper area and the nose. Lesions are ill-defined, erythematous, scaly, and crusted (eczematous) patches and plaques.

It is a narrow zone of complete hemolysis by theta toxin which is surrounded by a wider incomplete hemolysis by alpha-toxin.2) Naegler's reaction detects alpha toxin (phospholipase or lecithinase C). When Cl. perfringens is grown on a medium with the antitoxin spread on one half of the plate, colonies on the other half without the antitoxin will be surrounded by a zone of opacity. There will be no opacity around the colonies on the half of the plate with the antitoxin, due to the specific neutralisation of the alpha-toxin.* Alpha toxin is phospholipase (lecithinase-C).

Toxic shock syyndrome caused by staphylococcus is due to -
|
The pyrogenic toxin superantigens are a family of small-molecular-size, structurally similar proteins that are responsible for two diseases: TSS and food poisoning. TSS results from the ability of enterotoxins and TSST-1 to function as T cell mitogens. Enterotoxins bind directly to the invariant region of MHC--outside the MHC class II groove. The enterotoxins can then bind T cell receptors the vb chain, and thisbinding results in a dramatic overexpansion of T cell clones (up to 20% of the total T cell population). The consequence of this T cell expansion is a "cytokine storm," with the release of inflammatory mediators that include interferon g, IL-1, IL-6, TNF-a, and TNF-b. The resulting multisystem disease produces a constellation of findings that mimic those in endotoxin shock; however, the pathogenic mechanisms differ.

For a term small for date baby, true is –
|
First let me differentiate the following three terms
Low birth weight neonates
Preterm infant (Premature infant)
Small for gestational age (small for date)
i) Low birth weight
Any neonate weighing less than 2500 gms at birth irrespective of the gestational age.
ii) Preterm infant (premature infant)
Any neonate born before 37 weeks of gestation irrespective of the birth weight.
Because birth weight is a function of gestation, a preterm baby is expected to have less weight.
iii) Small for date (MGR)
Babies with a birth weight less than 10 percentile for that gestational age. These may be preterm (born before 37th week) or term (born between 37 to 42 weeks).
So, both preterm infant and small for date neonate have low birth weight.

True about location of Ig chromosome:
|
A i.e. lc- 2In humans, genes for light chains-Kappa (lc) is in chromosome 2; for light chain lambda (X) is in chromosome 22 and genes for heavy chains are in chromosome 14Q.Each of the 5 classes of immunoglobulin has a characterstic type of heavy chain - alpha (a) in IgA, gamma (y) in IgG, delta (8) in IgD, mu (.t) in IgM and epsilon (c) in IgE.Immunoglobin has 2 identical light (L) & 2 identical heavy (H) chains, each containing variable (V) & constant (C) regions. Variable regions of light- & heavy chains (i.e. VL & VH) bind to specifc antigen and form a pa of Fab (antigen binding fragment).IgM is natural antibody produced in primary response to antigen. It does not cross placenta, therefore, the fetus even though it carries an incompatible antigen, is protected from natural antibodies of mother. It fixes complementQ (like IgG) and agglutinates bacteria (like IgA & G). It has antigen receptors on B cells, surface (IgD is found on surface of B cells where it acts as a receptor for antigen).Newly mature B cells produce both IgM and IgD, which can switch to other class of immunoglobulin (i.e. IgG, IgA or IgE) in a process k/a isotype/class switching.

Inhalation agent of choice in head injury with raised ICT is ?
|
Ans. is 'a' i.e., Isoflurane Isoflurane It is an isomer of enflurane with similar propeies but 11/2 times more potent. BP falls due to vasodilation, while cardiac output is maintained inhalation anaesthetic of choice in Cardiac surgery (intravenous anaesthetic of choice for cardiac surgery is etomidate). It does not sensitize the hea to Adr --> Safe in pheochromocytoma. Isoflurane causes minimum increase in ICT Preferred agent in increased ICT. It does not provoke seizures --> preferred in neurosurgery. Uterine and skeletal muscle relaxant action is similar to halothane --> can be used for assisting version as an alternative to halothane. It causes significant respiratory depression. Isoflurane is the volatile agent of choice in liver disease as it has least effect on hepatic blood flow. It can cause coronary steal phenomenon. It can be used for day care surgery (also sevoflurane and desflurane). It is also used to produce controlled hypotension, as it causes maximum decrease in systemic vascular resistance.

POEMS Syndrome includes all, EXCEPT:
|
The features of this syndrome are polyneuropathy, organomegaly, endocrinopathy, multiple myeloma, and skin changes (POEMS). Patients usually have a severe, progressive sensorimotor polyneuropathy associated with sclerotic bone lesions from myeloma. Polyneuropathy occurs in ~1.4% of myelomas, but the POEMS syndrome is only a rare subset of that group. Unlike typical myeloma, hepatomegaly and lymphadenopathy occur in about two-thirds of patients, and splenomegaly is seen in one-third.

In a neonate, kidney is supplied by?
|
Upto 5th week of intrauterine life, kidney is in lumbar region and renal aeries are branches of common iliac aery (see above explanation). After that, differential growth of abdominal wall causes the kidney to ascent to lumbar region. Adult position (lumbar region of abdomen) is attained by 9th week. Druing progressive ascent, the aeries to kidney are derived from different levels of aoa. After full ascent, definitive renal aery is branch of aoa at 2nd lumbar segment. Thus, neonatal kidney is supplied by aoa.

Cold temperature slows the onset and progression of rigor mois. It is because of the slow onset and breakdown of ATP in cold weather. Rigor mois usually has an onset 1-2 hours after death and gets well established in the entire body in about 9-12hrs. Factors accelerating the onset of rigor mois are: Warm temperature Thin body built Aerobic exercise Strychnine poisoning (produces convulsions) Ref: Forensic Science: Fundamentals & Investigations By Anthony J.
