In Steiner's analysis, SNA demonstrates:

Relating the Maxilla to the Skull: The angle SNA is formed by joining the lines S-N and N-A . The mean reading for this angle is 82°. Steiners analysis demonstrates the position of maxilla and mandible in relation to the cranial base.  If the angular reading is more than 82°, it would indicate a relative forward positioning or protrusion of the maxilla. Conversely, should the reading be less than 82°, it would indicate a relative backward or recessive location of the maxilla.

Post traumatic stress disorder is differentiated from other anxiety disorders by which of the following symptoms?

This question is not about the diagnostic features of PTSD. This is about the differential diagnosis. PTSD is an anxiety disorder and it shares symptoms with other disorders. Impoant features in distinguishing the condition are given below. Differential diagnosis: Point 1: Etiologically significant trauma should be present for a diagnosis of PTSD. E.g. A traumatic event in the past. Point 2: 'Intentionality' or 'aboutness' is an impoant factor for PTSD. Nightmares, flashbacks or reliving experiences should be related to the past event. PTSD concerns memory - Intrusion of past stressors into the present. Point 3: Avoid a 'stimulus' or 'activity' that provokes the memory of the past event. In the above question, only reliving experience is mentioned as connected to the past experiences. Hence, that is the answer for this question. All other symptoms can be see in other anxiety disorders. Ref: Kaplan & Sadock's, Comprehensive Textbook of Psychiatry, 9th Edition, Page 2659

Polymorphic ventricular tachycardia can occur when terfenadine(antihistaminic):

Torsades de pointes (polymorphic ventricular tachycardia) occurs when terfenadine is taken in higher doses or when hepatic metabolism is impaired by disease or by drugs which inhibit the cytochrome P450 responsible for metabolism of terfenadine. Drugs include erythromycin, clarithromycin, ketoconazole and itraconazole. Azithromycin and fluconazole that are excreted unchanged in the urine have not been associated with impaired metabolism of terfenadine. Terfenadine blocks the delayed rectifier potassium channels and prolongs cardiac repolarization and the QT interval.

Which of the following nerve is involved in Frey's syndrome?

Syndrome (Gustatory Sweating) aka auriculotemporal syndrome: Frey's syndrome arises as a complication of parotid surgery usually manifesting several months after the operation. lt is characterised by sweating and flushing of the preauricular skin during mastication causing nuisance to the person or social embarrassment. It is the result of damage to auriculotemporal nerve and aberrant innervation of sweat glands by parasympathetic secretomotor fibres which were destined for the parotid. Now instead of causing salivary secretion from the parotid, they cause secretion from the sweat glands. The condition can be treated by tympanic neurectomy which intercepts these parasympathetic fibres at the level of middle ear. Some people like to place a sheet of fascia lata between the skin and the underlying fat to prevent secretomotor fibres reaching the sweat glands. Generally, no treatment other than reassurance is required in most of these patients. Also known as Crocodile tears (gustatory lacrimation): There is unilateral lacrimation with mastication. This is due to faulty regeneration of parasympathetic fibres which now supply lacrimal gland instead of the salivary glands. It can be treated by section of greater superficial petrosal nerve or tympanic neurectomy.

Opening of mouth is caused by:

Ans. A Lateral pterygoidRef: Grays, 41st ed. pg. 507-508* The primary function of the lateral pterygoid muscle is to pull the head of the condyle out of the mandibular fossa along the articular eminence to protrude the mandible.* The effort of the lateral pterygoid muscles acts in helping lower the mandible and open the jaw whereas unilteral action of a lateral pterygoid produces contralateral excursion (a form of mastication), usually performed in concert with the medial pterygoids.* Unlike the other three muscles of mastication, the lateral pterygoid is the only muscle of mastication that assists in depressing the mandible i.e. opening the jaw. At the beginning of this action it is assisted by the digastric, mylohyoid and geniohyoid muscles.

BSS plus a balanced salt solution enhanced with bicarbonate, dextrose and glutathione. It is specially used for surgeries requiring prolonged irrigation such as phacoemulsification, pars plana vitrectomy and automated extracapsular cataract extraction. Balanced sterile solution is a sterile physiologically balanced irrigating fluid. It is the most frequently used solution during ophthalmic surgery to keep the cornea from drying out. BSS plus solution causes less corneal edema and endothelial cell damage following vitrectomy. The glutathione protects against depletion of endothelial ATP levels and maintains the integrity of the cell membrane by counteracting endogenous and exogenous oxidative agents.

Which of the following clinical situations is associated with an increase in predominantly conjugated ("direct") bilirubin?

Of the conditions listed, only pancreatic head tumors are associated with an increase in conjugated ("direct") bilirubin (obstructive jaundice). Increased levels of unconjugated ("direct") bilirubin result from hemolysis over liver defects that impair uptake or conjugation mechanism in liver cells (Gilbe's syndrome, Crigler- Najjar syndrome) positive. Unconjugated bilirubin may cross the immature blood brain Barrier of the newborn and cause Kernicterus. The physiologic jaundice of the newborn observed during the first week of bih is usually mild and due to relatively immature liver conjugation. Ref: Cothren C., Biffl W.L., Moore E.E. (2010).

Five days after an uneventful cholecystectomy, an asymptomatic middle-aged woman is found to have a serum sodium level of 125 mEq/L. Which of the following is the most appropriate management strategy for this patient?

The initial, and often definitive, management of hyponatremia is free-water restriction. Symptomatic hyponatremia, which occurs at serum sodium levels less than or equal to 120 mEq/L, can result in headache, seizures, coma, and signs of increased intracranial pressure and may require infusion of hypeonic saline. Rapid correction should be avoided so as not to cause central pontine myelinolysis, manifested by neurologic symptoms ranging from seizures to brain damage and death. Additionally, a search for the underlying etiology of the hyponatremia should be undeaken. Acute severe hyponatremia sometimes occurs following elective surgical procedures due to a combination of appropriate stimulation of antidiuretic hormone and injudicious administration of excess free water in the first few postoperative days. Other potential etiologies include hyperosmolarity with free-water shifts from the intra- to the extracellular compament (eg, hyperglycemia), sodium depletion (eg, gastrointestinal or renal losses, insufficient intake), dilution (eg, drug-induced), and the syndrome of inappropriate secretion of antidiuretic hormone (SIADH).

Thymic hypoplsia is seen in which of the following

Ref Robbins 9/e p224 Thymic Hypoplasia: DiGeorge Syndrome DiGeorge syndrome results from a congenital defect in thymic development with deficient T cell maturation. T cells are absent in the lymph nodes, spleen, and peripheral blood, and infants with this defect are extremely vulnera- ble to viral, fungal, and protozoal infections. Patients are also susceptible to infection with intracellular bacteria, because of defective T cell-mediated immunity. B cells and serum immunoglobulins are generally unaffected. The disorder is a consequence of a developmental mal- formation affecting the third and fouh pharyngeal pouches, structures that give rise to the thymus, parathy- roid glands, and poions of the face and aoic arch. Thus, in addition to the thymic and T cell defects, there may be parathyroid gland hypoplasia, resulting in hypocalce- mic tetany, as well as additional midline developmental abnormalities. In 90% of cases of DiGeorge syndrome there is a deletion affecting chromosomal region 22q11, as discussed in Chapter 6. Transplantation of thymic tissue has successfully treated some affected infants. In patients with paial defects, immunity may improve spontane- ously with age.

True about primary peritonitis

(D) Occurs with Cirrhosis of liver # # PRIMARY (SPONTANEOUS) BACTERIAL PERITONITIS> Peritonitis is either primary (without an apparent source of contamination) or secondary.> The types of organisms found and the clinical presentations of these two processes are different. In adults, primary bacterial peritonitis (PBP) occurs most commonly in conjunction with cirrhosis of the liver (frequently the result of alcoholism).> However, the disease has been reported in adults with metastatic malignant disease, postnecrotic cirrhosis, chronic active hepatitis, acute viral hepatitis, congestive heart failure, systemic lupus erythematosus, and lymphedema as well as in patients with no underlying disease. PBP virtually always develops in patients with ascites.> While enteric gram-negative bacilli such as Escherichia coli are most commonly encountered, gram-positive organisms such as streptococci, enterococci, or even pneumococci are sometimes found.> In PBP, a single organism is typically isolated; anaerobes are found less frequently in PBP than in secondary peritonitis, in which a mixed flora including anaerobes is the rule. In fact, if PBP is suspected and multiple organisms including anaerobes are recovered from the peritoneal fluid, the diagnosis must be reconsidered and a source of secondary peritonitis sought.

Enterobius commonly inhabit the: September 2011

Ans. D: Caecum Adult Enterobius vermicularis worms inhabit the caecum, appendix and adjacent poions of the ascending colon, lying closely applied to the mucosal surface. Pinworm (genus En terobius)/Threadworm/Seatworm, It is a nematode (roundworm) and a common human intestinal parasite, especially in children. It inhabits the caecum, appendix and adjacent poion of the ascending colon, lying closely applied to the mucosal surface It causes enterobiasis, or less precisely as oxyuriasis in reference to the family Oxyuridae. The pinworm appears as a white, small and delicate nematode. The adult female has a sharply pointed posterior end, is 8 to 13 millimeters long, and 0.5 millimeter thick. The adult male is considerably smaller, measuring 2 to 5 millimeters long and 0.2 millimeter thick, and has a curved posterior end. The eggs are translucent and have a surface that adheres to environmental objects. The eggs measure 50 to 60 micrometers by 20 to 30 micrometers, and have a thick shell that is flattened on one side. The small size and colorlessness of the eggs make them invisible to the naked eye, except in barely visible clumps of thousands of eggs. Eggs may contain a developing embryo or a fully developed pinworm larva.Inside the host, the larvae grow to 140-150 micrometers in length Pinworms spread through human-to-human transmission, by ingesting (i.e., swallowing) infectious pinworm eggs and/or by anal sex. The eggs are hardy and can remain ble (i.e., infectious) in a moist environment for up to three weeks.They do not tolerate heat well, but can survive in low temperatures: two-thirds of the eggs are still ble after 18 hours at -8 degrees Celsius (18 degF). After the eggs have been initially deposited near the anus, they are readily transmitted to other surfaces through contamination. The surface of the eggs is sticky when laid, and the eggs are readily transmitted from their initial deposit near the anus to fingernails, hands, night-clothing and bed linen.From here, eggs are fuher transmitted to food, water, furniture, toys, bathroom fixtures and other objects.Household pets often carry the eggs in their fur, while not actually being infected. Dust containing eggs can become airborne and widely dispersed when dislodged from surfaces, for instance when shaking out bed clothes and linen.Consequently the eggs can enter the mouth and nose through inhalation, and be swallowed later. Although pinworms do not strictly multiply inside the body of their human host, some of the pinworm larvae may hatch on the anal mucosa, and migrate up the bowel and back into the gastrointestinal tract of the original host. This process is called retroinfection. Despite the limited, 13 week lifespan of individual pinworms, autoinfection (i.e., infection from the original host to itself), either through the anus-to-mouth route or through retroinfection, causes the pinworms to inhabit the same host indefinitely

1-a hydroxylation in Vitamin-D metabolism takes place in

Vitamin D is a fat-soluble vitamin molecule found in fish liver oils, and also produced in the skin when subjected to ultraviolet rays from sunlight. The main function of the vitamin is to increase the utilization of calcium and phosphorus in bones and teeth. A mixture of several forms of vitamin D: Vitamin D3 is synthesized in the skin upon exposure to ultraviolet light; in contrast, vitamin D2 is obtained only from the diet. Both vitamins D2 and D3 are metabolized to 25-hydroxyvitamin D in the liver, and then to the active 1,25 dihydroxy form in the kidney. Vitamin D has a major role in the intestinal absorption of calcium, bone calcium balance and renal excretion of calcium.Ref: Ganong&;s review of medical physiology;24th edition; page no-379

Herpesviruses Cancer by EBV:EBV is recognized as a cause of Burkitt's lymphoma, nasopharyngeal carcinoma, Hodgkins disease, and some other lymphomas. Sera from patients with Burkitt's lymphoma or nasopharyngeal carcinoma contain elevated levels of antibody to virus-specific antigens, and the tumor tissues contain EBV DNA and express a limited number of viral genes. EBV-associated B cell lymphomas are a complication for immunodeficient patients

Childhood Chronic ill health in childhood or adolescent IBD may result in growth failure, metabolic bone disease and delayed pubey. Loss of schooling and social contact, as well as frequent hospitalisation, can have impoant psychosocial consequences.Treatment is similar to that described for adults and may require glucocoicoids, immunosuppressive drugs, biological agents and surgery. Monitoring of height, weight and sexual development is crucial. Children with IBD should be managed by specialised paediatric gastroenterologists and transitioned to adult care in dedicated clinics . Pregnancy A women's ability to become pregnant is adversely affected by active IBD. Pre-conceptual counselling should focus on optimising disease control. During pregnancy, the rule of thirds applies: roughly one-third of women improve, one-third get worse and one-third remain stable with active disease. In the post-paum period, these changes sometimes reverse spontaneously. Drug therapy, including aminosalicylates, glucocoicoids Delayed growth and pubeal development: chronic active inflammation, malabsorption, malnutrition and long-term glucocoicoids contribute to sho stature and delayed development, with physical and psychological consequences. * Metabolic bone disease: more common with chronic disease beginning in childhood, resulting from chronic inflammation, dietary deficiency and malabsorption of calcium and vitamin D. * Drug side-effects and adherence issues: young people are more likely to require azathioprine or biological therapy than adults. Poor adherence to therapy is more common than with adults, as younger patients may feel well, lack self-motivation to adhere and believe that drugs are ineffective or cause side-effects. * Loss of time from education: physical illness, surgery, fatigue in chronic inflammatory bowel disease, privacy and dignity issues, and social isolation may all contribute. * Emotional difficulties: may result from challenges in coping with illness, problems with forming interpersonal relationships, and issues relating to body image or sexual function.

Storage form of thyroid hormone-

The synthesis and storage of thyroid hormones occurs between the follicular cells and the colloid. The storage form of thyroid hormone is thyroglobulin. Thyroglobulin is a large glycoprotein synthesized in the follicular cells and has a molecular weight of around 650 000 with about 140 tyrosine residues, depending on the form of thyroglobulin. Approximately one quaer of these residues is iodinated at the apical-colloid interface. Once iodinated, thyroglobulin is taken up into the colloid of the follicle where, still incorporated in the protein, a coupling reaction between pairs of iodinated tyrosine molecules occurs. The coupling of two tyrosine residues each iodinated at two positions (di-iodotyrosine, DIT) produces tetra-iodothyronine or thyroxine (T4 ) whilst the combination of DIT with mono-iodotyrosine (MIT) produces tri-iodothyronine (T3 ). Such coupling can occur within a single molecule of thyroglobulin or between dimerized molecules of the protein. This coupling is catalyzed by TPO. Thyroid hormones are stored in this state and are only released when the thyroglobulin molecule is taken back up into the follicular cells. Stimulated by TSH, thyroglobulin droplets are captured by the follicular cells by a process of pinocytosis. Fusion of the droplets with lysosomes results in hydrolysis of the thyroglobulin molecules and release of T3 and T4. Reference : page 2285 Harrison's Principles of Internal Medicine 19th edition
