| single | * Microscopically, the bone is of five types, namely lamellar (including both compact and cancellous), woven, fibrous, dentine and cement. 1. Lamellar bone: Most of the mature human bones, whether compact or cancellous, are composed of thin plates of bony tissue called lamellae. These are arranged in piles in a cancellous bone, but in concentric cylinders (Haversian system or secondary osteon) in a compact bone. 2. Woven Bone: seen in fetal bone, fracture repair and in cancer of bone 3. Fibrous bone is found in young foetal bones, but are common in reptiles and amphibia. 4. Dentine and 5. Cement occur in teeth. * Compact bone ( coical bone) In shaft (diaphysis) of long bone - lamellae arranged to form Haversian system - Bone marrow Yellow which stores fat after pubey. It is red before pubey - Hard and ivory-like * Cancelled bone spongy, or trabecular bone - In the epiphyses of long bone - arranged in a meshwork, so Haversian systems are not present - bone marrow red, produce RBCs, granular series of WBC and platelets - spongy * Nails are made of a tough protective protein called keratin - consists of the nail plate, the nail matrix and the nail bed below it, and the grooves surrounding it (Reference : BDC Handbook of General Anatomy , 5th edition, pg 39) | Anatomy | General anatomy |

| single | Laboratory diagnosis of HIV infection
Laboratory diagnosis is made by:
A. Antibody detection
It is the most common method used for diagnosis of HIV infection.
ELISA is the most sensitive test and therefore is the screening test of choice.
Western blot is the most specific (Confirmatory) test and therefore is the’gold standard’ for diagnosis.
Antibodies test usually nucleic acid or antigen.
B. Detection of HIV nucleic acid or antigen
P24 antigen detection by ELISA can be done 16 days after infection (earlier than antibody detection).
Nucleic acid detection tests are the earliest to become positive (12 days after infection), Most commonly used test is reverse transcriptase PCR, (RT-PCR), other methods used are DNA-PCR, RNA-PCR, RNA-bDNA (branched DNA), and RNA-NASBA (nuclei acid sequenced based assay).

| multi | ANSWER: (D) Water soluble low molecular weight contrast swallowREF: with textUse of non ionic water soluble contrast medium instead of barium is warranted when there is any risk of aspiration or esophageal leak. (Ref: Gastrointestinal Imaging: The Requisites By Giles W. Boland 4th ed page 2)Careful endoscopic assessment at the end of any procedure combined with a chest X-ray will identify many cases of perforation immediately. If not recognised immediately, then early and late suspected perforations should be assessed by a water-soluble contrast swallow. If this is negative, a dilute barium swallow should be considered. A CT scan can be used to replace a contrast swallow or as an adjunct to accurately delineate specific fluid collections. (Bailey 25th ed page 1015)Diagnosis of an esophageal perforation may be made radiographically. A chest roentgenogram may demonstrate a hydropneumothorax. A contrast esophagram is done using barium for a suspected thoracic perforation and Gastrografin for an abdominal perforation. Barium is inert in the chest but causes peritonitis in the abdomen, whereas aspirated Gastrografin can cause life-threatening pneumonitis. A surgical endoscopy needs to be performed if the esophagram is negative or if operative intervention is planned. (Ref: Sabiston 18th ed chapter 41) | Surgery | Esophageal Perforation |

It is accompanied by a significant increase in water insoluble proteins. However, the total protein content and distribution of cations remain normal. There may or may not be associated deposition of pigment urochrome and/or melanin derived from the amino acids in the lens. The nucleus may become diffusely cloudy (greyish) or tinted (yellow to black) due to deposition of pigments. In practice, the commonly observed pigmented nuclear cataracts are either amber, brown (cataracta brunescens) or black (cataracta nigra) and rarely reddish (cataracta rubra) in colour.

| multi | Ans. C: Hyperplastic polypsIt is now appreciated that hyperplastic polyps are without malignant potentialJuvenile polyps that are single and have been completely excised carry no significant increased risk of malignancy. Multiple juvenile polyps can be a sign of the familial juvenile polyposis syndrome. This has a significant risk (approximately 10 per cent) of subsequent colon cancer and also a possible increased risk of cancers of the stomach and duodenum (first pa of the small intestine).Juvenile polyposis (JP)Autosomal dominant.Multiple hamaomatous polyps of the colorectum (98%), stomach (13%), small bowel (6%)Juvenile polyps are usually pedunculated, smooth, lobulated with a vulnerable surface.Diagnostic criteria:- 5 or more juvenile polyps in the colon or rectum; OR- One juvenile polyp and positive family history of JP; OR- Juvenile polyps outside the colon or rectum, i.e. stomach/small bowel.Family history positive in 20-50%, suggesting high incidence of spontaneous mutations or low penetrance.Children/ adolescents often presents with iron deficiency anemia, hypoproteinemia and retarded growth. Also rectal prolapse or other congenital abnormalities (15%) in CVS, Urogenital tract and CNS.Cancer risk:- Increased risk, lifetime risk of 20-60% for colorectal cancer.- Median age at diagnosis is 35-40 years.- Increased risk for gastric and duodenal cancersGenetic testing- Germline mutations of the SMAD4 and BMPR1A are detected in 11-25% and 18-30% of patients of JPC.- Gastric polyposis seems to be more frequent and severe in patients with SMAD4 mutations.Treatment- Colectomy and gastric surgery in severe polyposis.Familial adenomatous polyposis (FAP)<1% of all colorectal cancers.Autosomal dominant inherited disease, > 100 colorectal adenomas, caused by germline mutations of the tumor suppressor gene APC (detectable in 80-90% of patients with typical FAP) Prevalence 1:10000 with penetrance close to 100%.25% of patients with FAP do not have positive family history. These are de novo germline mutations.Polyp development stas in distal colorectum at an average age of 15Majority of patients become symptomatic with bloody diarrhea by the age of 25Extracolonic manifestation:- Up to 90% of patients with FAP develop polyps in upper GIT- 30-40% gastric fundic gland polyposis and 5-10% gastric adenomas- Risk for gastric cancer not increased.Major causes of death in colectomized FAP patients are duodenal and ampullary cancer.Spigelman classification for polyposis in upper GIT to allow adequate follow up.Extra-intestinal manifestation of FAP include:- Desmoid tumours (10-20%)- Epidermoid cysts (30-50%)- Fibromas- Osteomas (often in the mandibula)Congenital hyperophy of the retinal pigment epithelium (70%)- Dental abnormalities. Gardner's syndrome:- Polyposis, epidermoid cysts, osteomaTurcot's syndrome in FAP- Polyposis, CNS tumours (medulloblastoma)Increased risk observed for:- Hepatoblastoma, follicular thyroid cancer, brain tumours (usually medulloblastoma).Treatment:- Procedure: Proctocolectomy with ileal-pouch-anal anastomosis (IPAA): Gold standard.Peutz Jeghers syndrome (PJS)Autosomal dominant.Special type of hamaomatous GI polyp (PJ polyp) and mucocutaneous melanin pigmentations.PJ polyps occur throughout alimentary tract with predilection for the small bowel.Mostly jejunal. Esophagus is spared. Rarely nose, gallbladder and ureter.Polyps characterized by extensive smooth muscle aborization throughout polyp.Pigment lesions in 95% of patients but may disappear with age. Mostly lips, peri-oral and intra-oral mucosa.Diagnostic criteria:2 or more PJ polyps- One PJ polyp and mucocutaneous pigment lesion- One PJ polyp and positive family history of PJS.Endoscopic or surgical excision of large or symptomatic polyps is recommended.Family history is negative in up to 45% of index cases indicating de novo germline mutations.Recurrent colicky abdominal pain due to intussusception in adolescence or young adulthood. Also occult bleeding with iron-deficiency anemia. Pigmentation not always present in childhood and may fade later in life.Intra-epithelial neoplasia predisposes to cancer - hamaoma-adenoma-carcinoma sequenceCancer risk:- 85% by age 70 years- 57% GI cancer.- Colorectal cancer most common with lifetime risk of 39%. Lifetime pancreatic cancer risk is 11%.Extraintestinal cancers include breast risk (31-50%), endometrium and ovary.Cancer uncommon before age 30 years.Almost all female patients with PJS develop potentially malignant ovarian tumour, the sex cord tumour with annular tubules (SCTAT). Malignant transformation in 20% of all cases. Seoli cell tumours considered as male equivalent of SCTAT with gynaecomastia.Genetic testing- PJS is caused by germline mutation of the STKII tumour suppressor gene. | Pathology | null |

Pilocarpine also acts on the ciliary muscleand causes it to contract. When the ciliary muscle contracts, it opens the trabecular meshwork through increased tension on the scleral spur. This action facilitates the rate that aqueous humor leaves the eye to decrease intraocular pressure | Pharmacology | Autonomic nervous system |

| multi | Answer 'a' i.e. Weightloss is commonest feature Symptoms of gastric cancer Earliest symptom is usually vague postprandial abdominal heaviness Most common symptom is weight loss Other symptoms are: - anorexia - abdominal pain (usually not severe) vomiting may be present and becomes a major feature if pyloric obstruction occurs. It may have coffee-ground colour due to bleeding by the tumor. - dysphagia may be the presenting symptom if the lesion is at the cardia. Paraneoplastic symptoms such as - Trousseau's syndrome (thrombophlebitis) - Acanthosis nigricans (hyperpigmentation of the axilla and groin) - Peripheral neuropathy Option b & c Spread of gastric carcinoma - intramural spread within the submucosa - direct spread through the gastric walls - lymphatic spread hematogenous - transperitoneal through peritoneal seedlings about option 'b' - I am not very sure, but it appears to be uncorrect. Most common secondaries are noted in intrabdominal and supraclavicular lymphnodes. Liver is the most common site for hematogenous spread of tumor (Harrison 16/e, p 525) Option 'd' - Barium meal is -75% sensitive for gastric cancer and is the simplest study to perform but it is not confirmatory. Endoscopy with biopsy is always needed if gastric Ca is suspected, to confirm the diagnosis. Harrison 16/e, p 526 writes - "Gastric adenocarcinoma is a relatively radioresistant tumor and adequate control of the primary tumor requires doses of external beam irradiation that exceeds the tolerance of surrounding structures, such as the bowel mucosa and the spinal cord. As a result, the major role of radiation therapy in patients has been palliation of pain." | Surgery | null |

| multi | Ans. A. Clostridium botulinum.(Ref. Nelson Textbook of Pediatrics, 19th ed. Chapter 367)Sudden infant death syndrome# Sudden infant death syndrome (SIDS) is the unexpected, sudden death of a child under age 1 in which an autopsy does not show an explainable cause of death.# SIDS is most likely to occur between 2 and 4 months of age. SIDS affects boys more often than girls. Most SIDS deaths occur in the winter.# The following have been linked to a baby's increased risk of SIDS:# Sleeping on the stomach# Being around cigarette smoke while in the womb or after being bom# Sleeping in the same bed as their parents (co-sleeping)# Soft bedding in the crib# Multiple birth babies (being a twin, triplet, etc.)# Premature birth# Having a brother or sister who had SIDS# Mothers who smoke or use illegal drugs# Being bom to a teen mother# Short time period between pregnancies# Late or no prenatal care# Living in poverty situations# Honey is the one identified, avoidable source of C botulinum spores for susceptible infants.# Because botulinal toxin is the most potent poison known (about 10-9 mg per kg of body weight given intravenously being a lethal amount for man), it appeared possible that rapid in vivo production of botulinal toxin might in some infants lead to sudden death if upper airway obstruction or apnea resulted from flaccidity of airway and respiratory muscles.# In a British study released May 29, 2008, researchers discovered that the common bacterial infections Staphylococcus aureus and Escherichia coli appear to be risk factors in some cases of SIDS. | Pediatrics | Infection |

| single | The lesion is a squamous cell carcinoma of the skin. Actinic keratosis, which is a hyperplastic lesion of sun-damaged skin, predisposes for squamous cell carcinoma. Another predisposing condition to remember is xeroderma pigmentosum, which predisposes for both squamous cell and basal cell carcinomas of skin. A nevus is a mole, containing characteristic cells called nevocellular cells. If the nevocellular cells are located at the dermal-epidermal junction (junctional nevus), in the dermis (dermal nevus), or both (compound nevus) they do not predispose for squamous cell carcinomas of the skin.

When asked to his family, they say that he has been muttering to self and gesticulating. There is no of psychiatric illness. Likely diagnosis is: | Dementia | Acute psychosis | Delirium | Delusional disorder | 1b
| single | B i.e. Acute psychosis- Delusions or hallucinations (suchas hearing voices in this case) with grossly disorganized speech and behavior (such as muttering to self, gesticulation, aggressiveness in this case) of acute onset with normal cognition & consciousness indicate the diagnosis of acute psychosis (i.e. psychosis of acute onset). This acute psychosis may be d/t psychotic disorder d/t general medical condition (such as high fever as in this case) or d/t brief psychotic disorder (DSMIVTR), or d/t acute and transient psychotic disorder (ICD-10). So here the term acute psychosis is used to depict the clinical picture not the cause of that clinical picture.Delirium can also present acute onset disorganized behavior (agitation) and speech (incoherent) with delusions or hallucinations but the delusions are poorly elaborated & transient, the course of disease is fluctuant (eg sun downing). And characteristically there is clouding of (disturbance in) consciousnesss (i.e. reduced clarity of awareness of the environment) and disorientation (change in cognition) in delirium. Just like psychosis clinical picture of delirium may also be d/t various reasons such as general medical condition / substance intoxication/ withdrawal.- Dementia is a chronic slow/insiduous process presenting with decrement in intellectual abilities (such as sho & long term memory, judgement, abstract thinking, impulse control, personal care and personality)Q.- Delusional disorder presents with nonbizarre delusions (involving situations that occur in real life) of at least 1 months durationQ. Apa from the impact of delusion (s) or its ramifications, functioning is not markedly impaired and behavior is not obviously odd or bizarre (i.e. criteria. A of schizophrenia has never been met).

| single | Genital HPV infection is extremely common and most often cause no symptoms. A propoion of individuals infected with low-risk HPV types such as HPV-6 or HPV-11 will develop genital was, whereas a subset of women with high-risk HPVs such as HPV-16 or HPV-18 will develop preneoplastic lesions of cervical intraepithelial neoplasia (CIN). Low-grade cervical dysplasias are common and most regress spontaneously. In contrast, the minority of lesions that progress to high-grade dysplasias tend to persist and/or progress to carcinomas in situ before becoming invasive cancers. The majority of adenocarcinomas of the cervix and of squamous cell cancers (SCC) of the vulva, vagina, penis and anus are caused by HPV-16 and HPV-18 (together accounting for about 70% of cases globally), the remaining 30% being due to other high-risk HPV types (such as HPV-31, -33, -35, -39, -45,-51, -66). HPV is also associated with other cancers of the anus, head and neck, and rarely, recurrent respiratory papillomatosis in children. | Gynaecology & Obstetrics | null |
