In the treatment of undiagnosed megaloblastic anemia, vitamin B12 and folic acid should be given together because :

Vitamin B12 is required for conversion of methionine to homocysteine and for the formation of succinyl CoA from methylmalonyl CoA. Deficiency of vitamin B12 results in megaloblastic anemia, GI manifestations and neurological abnormalities (due to demyelination). Folic acid alone will correct the symptoms of megaloblastic anemia but it does not prevent neurological abnormali­ties, which continue to proceed. Neurological abnormalities manifest initially in the form of loss of posterior column sensations (vibration, proprioception etc.), but later on, can result in subacute combined degeneration of the spinal cord.

Vitamin B12 acts as a cofactor for dihydrofolate reductase

Folic acid alone causes improvement of anemic symptoms but neurological dysfunction continues.

Vitamin B12, deficiency may result in methylfolate trap

Folic acid is required for conversion of methylmalonyl CoA to succinyl CoA.

Which is not true of malaria Eradication programmea) Started in 1953b) Modified plan started in 1970c) Incidence was 2 million cases in 1958d) Incidence decreased to 50,000 in 1961

National anti-malaria Programme The Programme began initially as National Malaria control Programme in 1953. Because of the spectacular success achieved in the control of malaria, the control programme, was converted into an eradication programe in 1958 with the object of eradicating malaria once and for all from the country. The programme went on well for sometimes. The incidence of malaria declined from 75 million cases and 8 lakhs death in 1953 to about 1-2 million cases and no death in 1972. But thereafter the programme suffered serious set backs. There was a sharp increase in malaria incidence, in 1976, there were 6.47 million cases with 59 deaths. The Govt of India in 1977 evolved a "Modified plan of operation" based on "effective control" rather than eradication. The plan has since been implemented and the incidence of malaria began to decline. However, there was gradual, increased in falciparum malaria incidence. Hence a programme for containment of P.falciparum was also launched within the NMEP. Note : Option 'c & d' were given in 19th/e. of Park : - "The incidence of malaria had declined sharply from 75 million cases in 1953 to 2 million cases in 1958". "The annual incidence of malaria cases in India escalated from 50000 in 1961, to a Peak of 6.4 million cases in 1976". Strategic Action plan for malaria control in India (2007-2012) Malaria control is now incorporated into the health service delivery programmes under the umbrella of NRHM. The strategies of National malaria control programme are as follows : - Malaria Control strategies The strategies for prevention and control of malaria and its transmission are-: 1. Surveillance and case management Case detection (passive and active). Early diagnosis and complete treatment. Sentinel surveillance. 2. Integrated vector management (IVM) Indoor residual spray (IRS). Insecticide treated bed nets (ITNs)/ Long Lasting Insecticidal Nets (LLINs). Antilarval measures including source reduction. 3. Epidemic preparadness and early response 4. Supportive interventions Capacity building  Behaviour change communication (BCC) Intersectoral collaboration Monitoring and evaluation Operational research and applied field research. Goals for strategic Plan 2007-2012 The main national goals for malaria control are given below : - At least 50 percent reduction in mortality due to malaria by the year 2010, as per National Health Policy document 2002. At least 80 percent of those suffering from malaria get correct, affordable and appropriate treatment within 24 hours of reporting to the health system, by the year 2012. At least 80 percent of those at high risk of malaria get protected by effective preventive measures such as ITNs/LLINs or IRS by 2012.

All of the following statements are true about congenital rubella except-

. <p>congenital rubella syndrome:- Refers to infants born with defects secondary to intrauterine infection or who manifest symptoms or signs of intrauterine infection sometime after bih. Congenital infection is considered to have occurred if the infant has IgM antibodies sholy after bih.( as IgM antibodies do not cross placenta,their presence indicate they must have been synthesised by the infant inutero) or if IgG antibodies persist for more than 6 months. At bih virus is easily detected in pharyngeal secretion,multiple organs, CSF ,urine and rectal swabs. Rubella infection inhibits cell division. The classic triad- deafness,cardiac malformation and cataract. Other defects include glaucoma, retinopathy, microcephalus, cerebral palsy, intrauterine growth retardation,hepatosplenomegaly, mental and motor retardation. These defects occuring singly/in combination is known as " congenital rubella syndrome ". Congenital rubella- chronic infection Acquired rubella- acute infection. The gestational age at which maternal infection occurs is a major determinant for extend of foetal infection. 1. First trimester- most disastrous as the organs are developing. Infection during this period results in abnormalities in 85% cases. 2. Second trimester- 16% cases. 3. After 20 weeks- bih defects uncommon. {Reference: park&;s textbook of preventive and social medicine, 23rd edition, pg no.151}</p>

Black malarial pigment is seen in: September 2009

Ans. B: P.falciparum In well-stained preparations the nuclei of the parasites are always stained red and the cytoplasm blue. The presence of malaria pigment is very characteristic of the older stages of Plasmodium sp. P. falciparum often contains a single black dot. P. vivax often contains countless fine golden yellow/brown specks of malaria pigment. In P. ovale and P. malariae the pigment inclusions are many and brownish black. Countless fine red spots in the red blood cell (Schiiffner's dots) can be seen in P. vivax and P. ovale (the more mature the parasite, the more dots). In P. ovale the dots are sometimes called James's dots. Sometimes a few flecks can be observed in P. falciparum (Maurer's dots or clefts). P. malariae almost never exhibits dots (Ziemann's dots). The visibility of these dots depends to a great extent on the acidity (pH) with which the thin slide preparation is stained (slightly alkaline: pH = 8 is best). The acidity is impoant because blood smears are usually stained for haematological tests with a slightly acid pH.

Conjunctivitis: It is one of the most common complication of herpes zoster. It may occur as mucopurulent conjunctivitis with petechial haemorrhages or acute follicular conjunctivitis with regional lymphadenopathy. Sometimes, severe necrotizing membranous inflammation may be seen. 2. Zoster keratitis: May precede the neuralgia or skin lesions. 3. Episcleritis and scleritis: These usually appear at the onset of the rash but are frequently concealed by the overlying conjunctivitis. 4. Iridocyclitis: It is of a frequent occurrence and may or may not be associated with keratitis. There may be associated hypopyon and hyphaema (acute haemorrhagic uveitis). 5. Acute retinal necrosis: 6. Anterior segment necrosis and phthisis bulbi. 7. Secondary glaucoma: It may occur due to trabeculitis in early stages and synechial angle closure in late stages.

Which statement is false about allosteric regulation?

Allosteric regulation is usually the mode of regulation for the first step in reaction pathways. Allosteric modulators can be activators or inhibitors.They bind non-covalently at allosteric/regulatory site. By binding at allosteric site, they induce changes in the active site, where substrate binds and they modulate the binding of substrate. Binding of dissociable ligands (allosteric regulation) achieve regulation of enzymic activity within seconds

It is usually the mode of regulation for the last step in reaction pathways

Cellular response is faster with allosteric control than by controlling enzyme concentration in the cell

The regulation usually is impoant to the conservation of energy and materials in cells

Allosteric modulators bind non-covalently at sites other than the active site and induce conformational changes in the enzyme

In treatment of osteosarcoma, all of the following are used EXCEPT:

Methotrexate (Mtx): It is one of the oldest and highly efficacious antineoplastic drugs; inhibits dihydrofolate reductase (DHFRase)-blocking the conversion of dihydrofolic acid (DHFA) to tetrahydrofolic acid (THFA) which is an essential coenzyme required for one carbon transfer reactions in de novo purine synthesis and amino acid interconversions. The inhibition is pseudoirreversible because Mtx has 50,000 times higher affinity for the enzyme than the normal substrate. Methotrexate is apparently curative in choriocarcinoma: 15-30 mg/ day for 5 days orally or 2G-40 mg/m2 BSA i.m. or i.v. twice weekly. It is highly effective in maintaining remission in children with acute leukaemias, but not good for inducing remission: 2.5-15 mg/day. It is also useful in other malignancies, rheumatoid ahritis, psoriasis and as immunosuppressant.The use of folinic acid rescue has permitted much higher doses of Mtx and has enlarged its scope to many difficult-to-treat neoplasms. USES: 1)NEOPLASMS 2)MENINGEAL LEUKEMIA 3)OSTEOSARCOMA 4)RHEUMATOID AHRITIS 5)PSORIASIS 6)BREAST CANCER 7)HEAD AND NECK CANCER 8)MYCOSIS FUNGOIDES Cyclophosphamide: It is inactive as such: produces few acute effects and is not locally damaging. Transformation into active metabolites (aldophosphamide, phosphoramidemustard) occurs in the liver, and a wide range of anti tumour actions is exeed. It has prominent immunosuppressant propey. Thus, it is one of the most popular anticancer drugs. It is less damaging to platelets, but alopecia and cystitis (due to another metabolite acrolein) are prominent. Chloramphenicol retards the metabolism of cyclophosphamide. USES: 1)MALIGNANT DISEASES 2)NEPHROTIC SYNDROME 3)JUVENILE IDIOPATHIC AHRITIS 4)LUPUS NEPHRITIS 5)BREAST CANCER 6)NON HODGKIN LYMPHOMA 7)SYSTEMIC SCLEROSIS Vincristine ( oncovin) :It is a rapidly acting drug, very useful for inducing remission in childhood acute leukaemia, but is not good for maintenance therapy.

A 20-year-old man presents with dysuria, urgency, and urethral discharge. Physical examination shows suppurative urethritis, with redness and swelling at the urethral meatus. Which of the following is the most likely etiology of urethritis in this patient?

Urethritis is the most common manifestation of sexually transmitted diseases in men, in whom it typically presents with urethral discharge. Both gonococcal and nongonococcal urethritis have an acute onset and are related to recent sexual intercourse. The infection manifests with urethral discharge, typically purulent and greenish yellow. Symptoms include pain or tingling at the meatus of the urethra and pain on micturition (dysuria). Redness and swelling of the urethral meatus are usually seen in both sexes. In gonococcal urethritis, the urethral discharge contains N. gonorrhoeae, which can be identified microscopically in smears of the urethral exudates. The other choices do not present with urethral suppurative discharge.Diagnosis: Gonorrhea, urethritis

Cholesterol present in LDL

On accumulation in the cell inhibits replenishment of LDL receptors If LDL cholesterol is increased inside the cell, it down regulates LDL receptors so that further uptake is inhibited. HDL cholesterol is the cholesterol that is removed from peripheral tissues; LDL cholesterol represents the cholesterol which is to be delivered to peripheral tissues. LDL binds to LDL receptors and whole LDL particle is endocytosed by receptor mediated endocytosis via clathrin-coated pits (not by diffusion:- diffusion and endocytosis are different processes). Intracellular cholesterol activates intracellular enzyme acyl-CoA cholesterol acyl transferase (ACAT).

Irreversible Injury: Defect in membrane function in general, and plasma membrane in particular, is the most important event in irreversible cell injury in ischaemia. Oxygen deprivation causes shift of calcium from mitochondria and endoplasmic reticulum into the cytosol. Increased level of calcium in the cytosol activates endogenous phospholipases from ischaemic tissue which degrade membrane phospholipids progressively which are the main constituent of the lipid bilayer membrane. An alternate hypothesis is decreased replacement-synthesis of membrane phospholipids due to reduced ATP. Myelin figures & cellular swelling are the changes seen in Reversible cell injury.

Ans: A (Debridement) Ref: Campbell's Operative Orthopaedics, 11th editionExplanation:Management of Open FracturesThree components of open fracture management are:o Aggressive wound debridement.o Definitive fracture stabilization with internal or external fixation; and o Delayed wound closure.Of these wound debridement is the first and most important step to avoid infection.Tscherne Classification of Open Fracture Management into Four Eras:The era of life preservation / preantiseptic era: Until 20th century.The era of limb preservation: During World War I and World Warll.The era of infection avoidance: Until the mid-1960s when antibiotic came into use.The era of functional preservation: At present; management consists of aggressive wound debridement, definitive fracture stabilization with internal or external fixation, and delayed wound closure.Gustilo, Burgess, Tscherne and AO-ASIF group recommendations for open fractures:1.Treat open fractures as emergencies.2.Perform a thorough initial evaluation to diagnose life-threatening and limb-threatening injuries.3.Begin appropriate antibiotic therapy in emergency department and continue treatment for 2 to 3 days only.4.Immediately debride the wound of contaminated and devitalized tissue, copiously irrigate, and repeat debridement within 24 to 72 hours.5.Stabilize the fracture with the method determined at initial evaluation.6.Leave the wound open (Controversial).7.Perform early autogenous cancellous bone grafting.8.Rehabilitate the involved extremity aggressively.Modified Gustilo-Anderson Classification for Open FracturesType I open fractures: Clean wound less than 1 cm long.Type II open fractures: Laceration more than 1 cm long, no extensive soft-tissue damage, skin flaps or avulsions.Type IMA open fractures: Extensive soft-tissue lacerations or flaps, but maintain adequate soft-tissue coverage of bone, or they result from high-energy trauma regardless of the size of the wound. Includes segmental or severely comminuted fractures, even those with 1 cm lacerations.Type NIB open fractures: Extensive soft-tissue loss with periosteal stripping and bony exposure; usually massively contaminated.Type MIC open fractures: Open fractures with an arterial injury that requires repair regardless of the size of the soft-tissue wound.

Which of the following cells Contain organelles needed for the secretion of a proteinaceous product

Pancreatic acini - The secretory elements of the exocrine pancreas are long and tubular (but they are usually described as acini as they appear rounded or oval in sections). Their lumen is small. Secretory Cells - The cells lining the alveoli appear triangular in section, and have spherical nuclei located basally. In sections stained with haematoxylin and eosin the cytoplasm is highly basophilic (blue) paicularly in the basal pa. With suitable fixation and staining numerous secretory (or zymogen) granules can be demonstrated in the cytoplasm, specially in the apical pa of the cell. These granules are eosinophilic. They decrease considerably after the cell has poured out its secretion. With the EM the cells lining the alveoli show features that are typical of secretory cells. Their basal cytoplasm is packed with rough endoplasmic reticulum (this being responsible for the basophilia of this region). A well developed Golgi complex is present in the supranuclear pa of the cell. Numerous secretory granules (membrane bound, and filled with enzymes) occupy the greater pa of the cytoplasm (except the most basal pa).

The following statements concerning the abdominal part of the sympathetic trunk are not true except:

The abdominal portion of the sympathetic trunk is situated in front of the vertebral column, along the medial margin of the Psoas major. It consists usually of four lumbar ganglia, connected together by interganglionic cords. It is continuous above with the thoracic portion beneath the medial lumbocostal arch, and below with the pelvic portion behind the common iliac artery. The ganglia are of small size, and placed much nearer the median line than are the thoracic ganglia. Gray rami communicantes pass from all the ganglia to the lumbar spinal nerves. The first and second, and sometimes the third, lumbar nerves send white rami communicantes to the corresponding ganglia. The rami communicantes are of considerable length, and accompany the lumbar arteries around the sides of the bodies of the vertebrae, passing beneath the fibrous arches from which some of the fibers of the Psoas major arise.

Doppler ultrasonography (duplex) has become the best initial test for screening patients with carotid disease. It has become a highly accurate test, often obviating the need for carotid arteriography prior to carotid endarterectomy. Carotid arteriography remains the "gold standard" when quantifying the degree of carotid stenosis, but it is usually performed after noninvasive testing suggests significant stenosis. Spiral CT angiography is a new noninvasive modality that has been used to evaluate many segments of the vascular tree, but as yet its accuracy does not approach that of standard arteriography and it would certainly not be used in the initial evaluation of a patient with an asymptomatic bruit. Magnetic resonance arteriography (MRA) is also a relatively new modality that has enjoyed moderate success in the investigation of carotid disease. Although not quite as accurate as standard arteriography, it has been used in conjunction with the duplex as a complementary study. Once again, because of its cost, MRA would not be used as the primary screening modality. Transcranial Doppler studies are used to assess the intracranial vasculature.

A 46-year-old man presents with diffuse chest pain at rest and recent history of cough, fever and rhinor - rhea lasting for 3 days.

Ans. (a) Acute pericarditis.The tracing reveals sinus rhythm at approximately 75 beats/ min. The PR interval is prolonged to 200 milliseconds consistent with borderline first-degree AV block. The QRS axis and intervals are normal.ST elevations with concave upward morphology are seen in I and aVL, II and aVF, and V2 through V6. No Q waves are present. Furthermore, subtle PR-segment depression is seen in leads I and II. The differential diagnosis for ST-segment elevation includes, among other things, acute myocardial infarction, pericarditis, and left ventricular aneurysm. In this case, the upward concavity of the ST segment, the PR-segment depression, the lack of Q waves, and the diffuse nature of the ST-segment elevation in more than one coronary artery distribution make pericarditis the likely etiology. Patients with pericarditis will complain of chest pain, typically described as sharp and pleuritic. Radiation is to the trapezius ridge. The pain is improved with sitting up and leaning forward and worsened by leaning backward.

Ans. b (50%). (Ref. Shorttext book, Anaesthesia, 2nd ed., 54-55)Anesthetic potency of volatile anesthetics is measured by MAC. MAC represents the alveolar concentration of an anesthetic (at one atmosphere) that prevents movement in 50 percent of the subjects in response to pain.MINIMUM ALVEOLAR CONCENTRATION (MAC) - MAC = 1/ potency of drug# For determination of MAC in humans, the usual stimulus used is surgical skin incision.# It represents after a short time the partial pressure of the anesthetic in the central nervous system (CNS) and it is therefore the most useful index of anesthetic potency.# MAC is age-dependent, being lowest in newborns, reaching a peak in infants, and then decreasing progressively with increasing age.# The MAC can also be altered following administration of opioids.# As a rule of thumb, the addition of every one percent of alveolar nitrous oxide to another inhalation anesthetic will decrease in the MAC of that gas about one percent.# Increases in MAC result from hyperthermia and hypernatremia.# Decreases in MAC can result from hypothermia, hyponatremia, pregnancy, hypotension, and drugs such as lithium, lidocaine, opioids, and alpha2 agonists.Minimum alveolar concentration of inhaled anesthetics in 100% oxygen:- Halothane 0.74 percent- Enflurane 1.68 percent- Isoflurane 1.15 percent- Desflurane 6.3 percent- Sevoflurane 2.0 percent- Nitrous oxide 104 percent Factors increasing MACFactors decreasing MACDrugs decreasing MAC1) Hyperthermia2) MAO inhibitors3) Hypernatremia4) Alcohol abuse (chronic)1) Hyperthermia2) Hypoxia3) Metabolic acidosis4) Pregnancy5) Alcohol abuse (acute).1) Opiods, Pancuronium2) Propofol, Ketamine3) Benzodiazepines4) Barbiturates, Lidocaine5) Clonidine.

Useful diagnostic studies in the evaluation of upper-extremity pain include all of the following, EXCEPT:

Pain in the upper extremity may be of musculoskeletal or neurologic origin. Compression of the nerves supplying the upper extremity can occur at various levels from the spinal cord all the way down to the fingers. Cervical spine x-ray is helpful for detecting bony abnormalities, which may cause nerve compression. Pancoast's tumor, which can be demonstrated on chest x-ray, may be responsible for pain. Neural conduction studies of the median nerve may disclose the presence of carpal tunnel syndrome as the cause of pain. Finkelstein's test produces pain in patients with de Quervain's disease. The test is performed by asking the patient to grab his own thumb with the other fingers of the same hand and then move the wrist in the ulnar direction. If pain is elicited, then the test is positive. Adson's test is very helpful in detecting the presence or absence of collateral circulation between the radial and ulnar aeries and is not diagnostic for pain. Ref: Rapp J.H., MacTagga J. (2010). Chapter 34. Aeries. In G.M. Dohey (Ed),CURRENT Diagnosis & Treatment: Surgery, 13e.

Sperm acquires motility in ?

Ans. is 'c' i.e., Epididymis Spermatozoa leaving the testis (seminiferous ubules) are not fully mobile. They continue their maturation and acquire their mobility during their passage through epididymis. From epididymis they come to vas deference, distal end of which also receives the secretions of seminal vesicle, and continues as the ejeculatory duct. The ejeculatory duct joins the prostatic urethra. Once ejeculated into the the female, vaginal secretions improve the motility and feilizing ability of sperms. Fuher exposure to secretions of female genital tract (in uterus and/or fallopian tube) fuher improves the mobility and feilizing ability of the sperms. The beneficial effects of stay in the female genital tract are collectively called capacitation, from the isthmus, capacitated sperms move rapidly to the ampullas, where feilization takes place.

Management of Osteoradionecrosis would be:

Treatment of osteoradionecrosis at the present time is unsatisfactory. Decortication with sequestrectomy and hyperbaric oxygen with antibiotics have been used with limited success because of poor healing after surgery. Conservative approaches with the aim to maintain the integrity of the lower border of the mandible, keeping the site free of infection and the patient free of pain, may in the long-term prove more successful. The risk for osteoradionecrosis is greater in the presence of odontogenic or periodontal disease and in individuals with poor oral hygiene or ill-fitting dentures. Patients should be referred for dental care before undergoing a course of radiation therapy to minimize radiation caries and osteoradionecrosis. Radiation caries can be minimized by restoring all carious lesions before radiation therapy and initiating preventive techniques of good oral hygiene and daily topical fluoride.

Which of the following maternal complication during pregnancy result in giving bih to a large baby?

Maternal development of gestational diabetes result in fetal macrosomia. The pathophysiology of fetal macrosomia is not very clear but it seems clear that fetal hyperinsulinemia is one driving force. The insulin like growth factor, as well as fibroblast growth factor, also are involved, so a hyperinsulinemic state with increased levels of some growth factors, with increased expression of GLUT proteins in syncytiotrophoblast, may promote excessive fetal growth. It could also be due to elevated levels of maternal free fatty acid which leads to its increased transfer to the fetus accelerating triglyceride synthesis and resulting in adiposity.

He has been brought for psychiatric evaluation as recently he has been denying any memory of taking loans from the bank. Interestingly, all other memory functioning is pretty intact. This is suggestive of:

Dissociative Amnesia: Commonest clinical type of dissociative disorder. Occurs mostly in adolescent and young adults. Severe psychological trauma, the patient temporarily and unconsciously shuts down the memory of the traumatic event Circumscribed loss of traumatic memory is seen in these individuals The other memories are intact and this cannot be explained by normal forgetting Treatment: Suppoive psychotherapy Identify trauma related cognitive distoions and help the individual cope with adaptive behaviours Drug assisted interview could be beneficial to elicit information- abreaction

A 55-year-old man is admitted to the hospital for an iliofemoral bypass. The operation is performed successfully and the blood flow between the iliac and femoral arteries is restored. During rehabilitation which of the following arteries should be palpated to monitor good circulation of the lower limb?

The dorsalis pedis is the continuation of the anterior tibial artery into the foot, as it passes the distal end of the tibia and the ankle joint. The pulse of the dorsalis pedis can be felt between the tendon of the extensor hallucis longus and the tendon of the extensor digitorum longus to the second toe. A strong pulse is a positive indicator of circulation through the limb. The fibular (peroneal) artery is a branch of the posterior tibial artery and passes in the calf between the flexor hallucis longus and tibialis posterior, making it difficult to palpate. The deep plantar artery, the extension of the first dorsal interosseous or lateral plantar arteries, passes deep to the aponeurotic tissues and central muscles of the foot, making palpation unlikely. The dorsal metatarsal branches of the dorsalis pedis pass under cover of the extensor digitorum longus and brevis tendons. Palpable pulses of the first or other dorsal metatarsal arteries can therefore be difficult to detect.
