(A) Spondylisthesis# Spondylolisthesis is the forward displacement of a vertebra, especially the fifth lumbar vertebra, most commonly occurring after a break or fracture. Backward displacement is referred to as retrolisthesis.> Variant "listhesis," resulting from division of this compound word, is sometimes applied in conjunction with scoliosis. These "slips" occur most commonly in the lumbar spine. Spondylolysis (a defect or fracture of the pars interarticularis of the vertebral arch-appears as Scotty dog sign or Scottish terrier sign in oblique view X-Ray) is the most common cause of spondylolisthesis, which should not be confused with a slipped disc, in which one of the spinal discs in between the vertebrae has ruptured.> Hangman's fracture is a specific type of spondylolisthesis where the C2 vertebra is displaced anteriorly relative to the C3 vertebra due to fractures of the C2 vertebra's pedicles.

The yellow color is due to degradation of hemoglobin to bilirubin. Deoxyhemoglobin is responsible for bluish bruise seen on the first day after the injury. Bruises change color over time, because of the degradation of haemoglobin in the blood. However, the timescale of this degradation is not fixed, and it is therefore possible only to give a rough estimation of the age of the bruise. Colour changes are: Dark blue/ purple (fresh) Blue Brown Green Yellow

Bitewing (also called interproximal) images include the crowns of the maxillary and mandibular teeth and the alveolar crest on the same receptor.   Bitewing receptors are particularly valuable for detecting interproximal caries in the early stages of development before it becomes clinically apparent. Because of the horizontal angle of the X-ray beam, these radiographs also may reveal secondary caries below restorations that may escape recognition in the periapical views. Bitewing projections are also useful for evaluating the periodontal condition. They provide a good perspective of the alveolar bone crest, and changes in bone height can be assessed accurately through comparison with the adjacent teeth. In addition, because of the angle of projection directly through the interproximal spaces, the bitewing receptor is especially effective and useful for detecting calculus deposits in interproximal areas. (Because of its relatively low radiodensity, calculus is better visualized on images made with reduced exposure). Oral radiology White and Pharaoh; 7th ed. Page no 114

Ref Robbins 8/e p315,9/e p328 Hepatitis C virus is only oncogenic RNA virus in the options.otherd mentioned are oncogenic DNA viruses Hepatitis C Virus Epidemiology and Transmission. HCV also is a major cause of liver disease. The worldwide carrier rate is esti- mated at 175 million persons (a 3% prevalence rate, ranging widely from 0.1% to 12%, depending on the country). Per- sistent chronic infection exists in 3 to 4 million persons in the United States, where the number of newly acquired HCV infections per year dropped from 180,000 in the mid- 1980s to about 19,000 in 2006. This welcome change resulted from the marked reduction in transfusion-associated hepa- titis C (as a result of screening procedures) and a decline of infections in intravenous drug abusers (related to prac- tices motivated by fear of human immunodeficiency virus infection). However, the death rate from HCV will con- tinue to climb for 20 to 25 years, because of the decades- long lag time between acute infection and liver failure. The major route of transmission is through blood inoculation, with intravenous drug use accounting for at least 60% of cases in the United States. Transmission by blood products is now for- tunately rare, accounting for only 4% of all acute HCV infections. Occupational exposure among health care workers accounts for another 4% of cases. The rates of sexual transmission and veical transmission are low. Infections of unknown origin account for 9% to 27% of cases. HCV infection has a much higher rate than HBV of pro- gression to chronic disease and eventual cirrhosis (Fig. 15-13). In fact, hepatitis C is the condition that most frequently necessitates liver transplantation in the United States. Viral Structure and Genome. HCV is a positive-sense single-stranded RNA virus belonging to the family Flavi- viridae. It contains highly conserved 5'- and 3'-terminal regions that flank a single open reading frame of nearly 9500 nucleotides that encode structural and nonstructural proteins. HCV is subclassified into six genotypes, based on the genetic sequence. Moreover, because of the poor fidel- ity of RNA replication, an infected person may carry many HCV variants, called quasispecies. The relationships between quasispecies and disease progression are being investi- gated, but it seems that high multiplicity of quasispecies is associated with worse prognosis. In addition, this variabil- ity seriously hampers effos to develop an HCV vaccine.

The Beta-chain of Hb begins with valine and histidine. Both these amino acids are impoant in the synthesis and structure of heamoglobin. Alignment according to helical designation makes homology evident: Residue F8 is the proximal heme-linked histidine, and the histidine on the distal side of the heme is E7. The iron atom is linked by a coordinate bond to the imidazole nitrogen (N) of histidine F8. The E7 distal histidine, on the other side of the heme plane, is not bonded to the iron atom but is very close to the ligand-binding site. Ref: Natarajan K., Townes T.M., Kutlar A. (2010).

A schwannoma (also known as acoustic neuroma, acoustic neurinoma, or acoustic neurilemoma) is a benign, usually slow-growing tumor that develops from the vestibular nerves supplying the inner ear. The tumor comes from an overproduction of Schwann cells--the cells that normally wrap around nerve fibers like onion skin to help suppo and insulate nerves. As the vestibular schwannoma grows, it presses against the hearing and balance nerves, usually causing unilateral (one-sided) or asymmetric hearing loss, tinnitus (ringing in the ear), and dizziness/loss of balance. It comprises 5-10% of all intracranial neoplasms in adults. Incidence peaks in the fifth and sixth decades and both sexes are affected equally.

Baonella henselae is the infective agent of cat scratch disease, which generally presents as regional lymphadenopathy with or without low fevers and headaches. Baonella is a gram-variable pleomorphic rickettsial organism that is introduced to the skin in a cat bite or scratch. It produces a self-limited granulomatous response in the draining lymph nodes. Borrelia burgdorferi is a spirochetal organism that is transmitted by a tick bite (Ixodes spp.), producing Lyme disease. Lyme disease progresses from a skin rash to fevers, headache and pain over about one month. It may produce lymphadenopathy, but is not associated with granuloma formation. Chlamydia psittaci infection occurs after contact with infected bird droppings and produces an atypical pneumonia. The central nervous system may also be involved, but lymph nodes are spared. Chlamydia trachomatis is the chlamydial species that typically produces suppurative nodal granulomas (lymphogranuloma venereum). Coxiella burnetii infection is transmitted by inhaling dusts or drinking milk from infected mammals, especially sheep and cows. The disease in humans, Q fever, is marked by mild nonspecific symptoms or pneumonia, and may progress to myocarditis or hepatitis.

Ans. A. CroupCroup is the most common etiology for hoarseness, cough, and onset of acute stridor in febrile children. Symptoms of coryza may be absent, mild, or marked. The vast majority of children with croup recover without consequences or sequelae.Croup manifests as hoarseness, a seal-like barking cough, inspiratory stridor, and a variable degree of respiratory distress.However, morbidity is secondary to narrowing of the larynx and trachea below the level of the glottis (subglottic region), causing the characteristic audible inspiratory stridor. Parainfluenza viruses (types 1, 2, 3) are responsible for about 80% of croup cases. Urgent care or emergency department treatment of croup depends on the patient's degree of respiratory distress. Most children with mild croup symptoms can be successfully treated at home by their caregivers. In severe cases are treated by Dexamethasone and inhaled epinephrine.

Foy percent of retinoblastomas are heritable; the child inherits one mutant allele through the germline and a somatic mutation in the other allele occurs, resulting in the loss of function of that gene. This leads to tumor development, often with multiple tumors in both eyes. Penetrance, however, is not complete, since the second mutation is a chance event. Sixty percent of retinoblastomas are sporadic; both alleles are inactivated by somatic mutation. Because this is a rare event, tumors usually are in only one eye and present at a later age. To detect a mutation in the Rb gene and differentiate between heritable and sporadic cases of retinoblastoma, PCR is the most appropriate technique of the choices given. Using the appropriate primers, a deletion can be detected as a change in size of the DNA band amplified. In heritable cases, one chromosome will show the altered length from the deletion or the translocation in any cell in the body. In sporadic retinoblastoma, samples isolated from anywhere other than the tumor should have two normal alleles. DNA footprinting is a protocol used to detect specific protein binding to DNA molecules by comparing the fragmentation patterns of DNA bound with the protein of interest vs. unbound DNA following digestion with DNase I. If the bound protein protects against DNase I digestion, the position of the protein on the DNA can be deduced by the loss of the characteristic fragment. FACS uses antibodies coupled to fluorescent markers to determine cell surface molecules on whole cells. It is very useful for determining the stage of development or activation of cells, but does not give you any insight into the DNA. Nohern blotting, the RNA counterpa to Southern blotting, will determine the size and abundance of mRNA of a specific gene in a given sample of RNA. RNA is not able to be cleaved by restriction enzymes the way the DNA can; however, RNA molecules for different proteins are of different lengths. The sample is separated by agarose gel electrophoresis, transferred to a nitrocellulose membrane, and probed with a specific, labeled probe. This will be exposed to film and the bands will appear, revealing the size and the abundance of specific mRNAs.

The mitochondrial creatine kinase (CKm) is present in the mitochondrial intermembrane space, where it regenerates phosphocreatine (PCr) from mitochondrially generated ATP and creatine (Cr) impoed from the cytosol. Apa from the two mitochondrial CK isoenzyme forms, that is, ubiquitous mtCK (present in non-muscle tissues) and sarcomeric mtCK (present in sarcomeric muscle), there are three cytosolic CK isoforms present in the cytosol, depending on the tissue. Whereas MM-CK is expressed in sarcomeric muscle, that is, skeletal and cardiac muscle, MB-CK is expressed in cardiac muscle, and BB-CK is expressed in smooth muscle and in most non-muscle tissues. Mitochondrial mtCK and cytosolic CK are connected in a so-called PCr/Cr-shuttle or circuit. PCr generated by mtCK in mitochondria is shuttled to cytosolic CK that is coupled to ATP-dependent processes, e.g. ATPases, such as acto-myosin ATPase and calcium ATPase involved in muscle contraction, and sodium/potassium ATPase involved in sodium retention in the kidney. The bound cytosolic CK accepts the PCr shuttled through the cell and uses ADP to regenerate ATP, which can then be used as energy source by the ATPases (CK is associated intimately with the ATPases, forming a functionally coupled microcompament). PCr is not only an energy buffer but also a cellular transpo form of energy between subcellular sites of energy (ATP) production (mitochondria and glycolysis) and those of energy utilization (ATPases)Thus, CK enhances skeletal, cardiac, and smooth muscle contractility, and is involved in the generation of blood pressure Finally, high CK in the blood may be an indication of damage to CK-rich tissue, such as in rhabdomyolysis, myocardial infarction, myositis and myocarditis. This means creatine kinase in blood may be elevated in a wide range of clinical conditions including the use of medication such as statins; endocrine disorders such as hypothyroidism;and skeletal muscle diseases and disorders including malignant hypehermia,and neuroleptic malignant syndrome Ref Harrison20th edition pg 2567

Hepato-renal syndrome is a form of functional renal failure without renal pathology. Diagnosis is made in the presence of a large amount of ascites in patients who have a step-wise progressive increase in creatinine. Type 1 HRS is characterized by a progressive impairment in renal function and a significant reduction in creatinine clearance within 1-2 weeks of presentation. Type 2 HRS is characterized by a reduction in GFR with an elevation of S. creatinine level, but it is fairly stable and is associated with a better outcome than that of Type 1 HRS.

The features noted are those of Vibrio cholerae, the causative organism of the severe diarrheal disease, cholera. The diarrhea is the result of the action of the cholera enterotoxin, which acts by ADP-ribosylating adenylate cyclase, leading to increased cyclic AMP with secondary increased efflux of Cl- and H2O. World-wide, cholera is usually spread by fecally contaminated water. Pseudomonas is an oxidase-positive, gram-negative rod that characteristically produces the blue pigment, pyocyanin. Salmonella is a motile, gram-negative rod that is a non-lactose fermenter that produces H2S. Shigella are non-motile gram-negative rods.

Ans. c (Serotonin) (Ref. Harrison's medicine 17th ed., 2717; Kaplan & Sadock's Synopsis of Psychiatry, 10th ed., p. 901)Biological Factors in Suicide# Diminished central serotonin plays a role in suicidal behavior.# Low concentrations of CSF 5-HIAA also predicts future suicidal behavior.ETIOLOGY AND PATHOPHYSIOLOGY OF SUICIDE# There is some evidence that a functional polymorphism in the serotonin transporter (5-HTT) gene may interact with stressful life events to markedly increase risk of depression and suicide.# Postmortem examination of brains of suicide victims indicate altered noradrenergic activity, including increased binding to a1, - a2-, and b-adrenergic receptors in the cerebral cortex and decreased numbers of noradrenergic neurons in the locus coeruleus. Involvement of the serotonin system is suggested by findings of reduced plasma tryptophan levels, a decreased cerebrospinal fluid level of 5-hydroxyindolacetic acid (the principal metabolite of serotonin in brain), and decreased platelet serotonergic transporter binding. An increase in brain serotonin receptors in suicide victims and decreased expression of the cyclic AMP response element-binding (CREB) protein are also reported.# However, a decrement in mood after tryptophan reduction is considerably less robust in untreated patients, indicating that, if presynaptic serotonergic dysfunction occurs in depression, it likely plays a contributing rather than a causal role.DiseaseAssociated Change in NeuotransmitterSucidal behavior>|?HIAA and serotoninAnxiety| NE, GABA, |serotonin (5HT).DepressionNE and | serotonin (5HT).Alzheimer's dementia|ACh.Huntington's disease|GABA, |ACh.Schizophrenia| dopamine.Parkinson's disease|dopamine, | ACh.Educational point:NTCell BodiesTerminal locationNotesGlutamateGABACortexStriatumSpinal CordInter-neurons,Spinal CordAMPA (Na), NMDA (Ca), Ketamine, Stroke/ lschemiaAnticonvulsantsBarbiturateBenzodiazepineAnestheticsEtOHAchNucleus Basalis, SeptumCortex, HabenulaMemoryAlzheimer'sMyasthenia gravisDopamineSubstantia Nigra, VTACaudatePutamen, Limbic,Frontal Cortex,PituitaryParkinson'sDrug craving Psychosis| ProlactinNELocus CoeruleusCortex Limbic-5-HTRaphe nucleiForebrainLow levels in suicidal behavior.Acts as inhibitor of pain pathways in the cord.Sleep.Acts an inhibitor in higher regions of CNS is believed to help control the mood.MigraineAnti-anxiety.Anti-psychosis.Anti-emetic.Opioid peptidesHypothalamusBasal gangliaPituitaryHypothalamusEndorphinEnkephalinDynorphin

Ans. is d i.e. Prophylactic oophorectomy BRCA-1 and BRCA-2 are tumour suppressor genes. BRCA-1 is located on chromosome 17 and BRCA-2 on chromosome 13. Individuals who inherit mutations of BRCA-1 and BRCA-2 are highly susceptible for the development of hereditary breast or ovarian cancer. The mutations are inherited as autosomal dominant. Lifetime risk of Ovarian Ca in individual with these mutation - 25% Lifetime risk of Breast Ca in individual with these mutation - 50% BRCA-1 - (20-40% life time risk of ovarian cancer). BRCA-2 - (10-20% life time risk of ovarian cancer). Men in these families have an increased risk of prostate cancer. Strategies for prevention of hereditary ovarian cancer Genetic testing for susceptibility to ovarian cancer is rapidly becoming integrated into the clinical practice of oncology. Strategies have been adopted to reduce the incidence of ovarian cancer in patient with BRCA-1 and BRCA-2 mutations. Prophylactic oophorectomy : "The only proven way to prevent ovarian cancer is surgical oopherectomy. As another possible site of disease among these high risk patients is fallopian tube therefore should be removed. IN BRCA 1 or BRCA-2 mutation carriers, prophylactic bilateral salpingo-oophorectomy (B50) may be performed on either completion of childbearing or at age 35. In these patients, the procedure is approximately 90% effective in preventing epithelial ovarian cancer. In women with HNPCC, the risk reduction approaches 100%." Additional benefit of prophylactic oopherectomy is that the risk of breast cancer is reduced by 50-80%. Oral contraceptive pills : Data received from a multicenter control of genetic screening centers indicates that the use of oralcontraceptive pill is associated with 50% decreased risk for developing ovarian cancer in women who have mutation in either in BRCA - 1 or BRCA - 2. However there is sho term increased risk of developing breastcancer. Role of screening with CA 125 and transvaginal ultrasound : "In BRCA1- BRCA2 mutation carriers who donot wish to undergo prophylactic surgery a combination of through pelvic examination, transvaginal sonographic examination and CA 125 blood testing should be done". Oral contraceptive pills : Data received from a multicenter control of genetic screening centers indicates that the use of oral contraceptive pill is associated with 50% decreased risk for developing ovarian cancer in women who have mutation in either in BRCA - 1 or BRCA - 2.

Somatosensory evoked potential (SEP or SSEP) is the electrical activity of the brain that results from the stimulation of touch. SEP tests measure that activity and are a useful, noninvasive means of assessing somatosensory system functioning. By combining SEP recordings at different levels of the somatosensory pathways, it is possible to assess the transmission of the afferent volley from the periphery up to the coex. SEP components include a series of positive and negative deflections that can be elicited by viually any sensory stimuli. For example, SEPs can be obtained in response to a brief mechanical impact on the fingeip or to air puffs. However, SEPs are most commonly elicited by bipolar transcutaneous electrical stimulation applied on the skin over the trajectory of peripheral nerves of the upper limb (e.g., the median nerve) or lower limb (e.g., the posterior tibial nerve), and then recorded from the scalp. In general, somatosensory stimuli evoke early coical components (N25, P60, N80), generated in the contralateral primary somatosensory coex (S1), related to the processing of the physical stimulus attributes. About 100 ms after stimulus application, additional coical regions are activated, such as the secondary somatosensory coex (S2), and the posterior parietal and frontal coices, marked by a parietal P100 and bilateral frontal N140. SEPs are routinely used in neurology today to confirm and localize sensory abnormalities, to identify silent lesions and to monitor changes during surgical procedures. It is done mostly under General Anaesthesia to monitor neural pathway.
