| single | Cleft lip and cleft palate, also known as orofacial cleft, is a group of conditions that includes cleft lip (CL), cleft palate (CP), and both together (CLP).] A cleft lip contains an opening in the upper lip that may extend into the nose. The opening may be on one side, both sides, or in the middle. A cleft palate is when the roof of the mouth contains an opening into the nose. These disorders can result in feeding problems, speech problems, hearing problems, and frequent ear infections. Less than half the time the condition is associated with other disordersMultifacorial inheritance is the type of inheritance followed by traits that are determined by multiple factors both environmental and genetic. Environmental factors interact with many genes to generate a normally distributed susceptibiity.Some diseases for example myocardial infarction, congenital bih defects, cancer, diabetes, mental illnesses and Alzheimer diseases cause along with morbidity, premature moality in two out of three individuals during their lifetime. Many show clustering among families. However their inheritance pattern does not follow that of single gene disorders (Mendelian pattern of inheritance). These kind of diseases are thought to result from complex interactions between genetic and environmental factors, i.e. multifactorial inheritance pattern. | Pathology | General pathology |

beef8b2a-570a-4e6d-9299-c4eafef0db04 | Peptidoglycans are found in large quantities in cell wall of: March 2009 | Virus | Gram positive bacteria | Gram negative bacteria | All of the above | 1b
| multi | Ans. B: Gram positive bacteria The Bacteria (eubacteria), with the exception of the Chlamydias have a semirigid cell wall containing peptidoglycan. Gram negative bacteria's peptidoglycan layer is much thinner than in Gram-positive bacteria In general, the walls of gram positive bacteria have a simpler chemical nature than those of gram negative bacteria. The mycoplasmas are the only bacteria that naturally lack a cell wall. Mycoplasmas maintain a nearly even pressure between the outside environment and the cytoplasm by actively pumping out sodium ions. Their cytoplasmic membranes also contain sterols that most likely provide added strength. All other bacteria have a cell wall Peptidoglycan prevents osmotic lysis. Under the cytoplasmic membrane, bacteria concentrate dissolved nutrients (solute) through active transpo. As a result, the bacterium's cytoplasm is usually hypeonic to its surrounding environment and the net flow of free water is into the bacterium. Without a strong cell wall, the bacterium would burst from the osmotic pressure of the water flowing into the cell. | Microbiology | null |

| multi | Pre-eclampsia is a state of hypeension in pregnancy associated with proteinuria but with or without pathological edema. It is defined as a multi-system disorder of unknown etiology characterised by development of hypeension to the extent of 140/90 mm Hg or more with protienuria after the 20th week of pregnancy in a previously normotensive and a normoproteinuric patient. The typical pathological features are endothelial dysfunction and intense vasospasm. In pre-eclampsia, the glomerular filtration rate decreases. The decrease in glomerular filtration rate is as a result of the following physiological changes: Afferent glomerular aeriolar vasospasm Occlusion of the lumen of the glomerulus resulting from glomerular endotheliosis and fibrin deposits in the basement membrane Decreased renal blood flow Ref: Textbook of Obstetrics By D.C.

Physical examination revealed increased abdominal pain in the paraumbilical region, rebound tenderness over McBurney's point, and a positive psoas test. Blood tests showed marked leukocytosis. Which of the following is the most likely diagnosis? | Ectopic pregnancy | Appendicitis | Cholecystitis | Kidney stone | 1b
| single | Appendicitis is often characterized by acute inflammation and is indicated with both a positive psoas test and rebound pain over McBurney's point. McBurney's point lies 1 inch lateral to the midpoint of an imaginary line in the right lower quadrant, joining the anterior superior iliac spine and the umbilicus. In patients with appendicitis, rebound tenderness may be felt over McBurney's point after quick, deep compression of the left lower quadrant. An ectopic pregnancy would be associated with generalized abdominal pain instead of the localized pain felt over McBurney's point. Cholecystitis results from an inflammation of the gallbladder and would result in pain over the epigastric region shifting to the right hypochondriac region. Kidney stones result in referred pain to the lumbar or possibly inguinal regions. Perforation of the duodenum could result in pain to palpation of the abdomen, together with adynamic (paralytic) ileus, rigidity of the abdominal wall, and referral of pain to the shoulder. | Anatomy | Abdomen & Pelvis |

Which type of injury is seen in this patient? | Irreversible cell injury | Autolysis | Pyroptosis | Reversible cell injury | 3d
| single | Reversible cell injury:-
→ Hypoxia is the most common cause of cell injury.
→ Oxygen is an important requirement of mitochondria, for the formation of ATP, therefore hypoxia will result in earliest involvement of mitochondria, resulting in decreased formation of ATP.
→ Important organelles affected are
Cell membranes (require ATP for functioning of Na+ - K+ pump)
Endoplasmic reticulum (require ATP for protein synthesis)
Nucleus.
→ Swelling of organelles like endoplasmic reticulum, results in decreased protein synthesis.
→ Bleb results due to outpouching from the cell membrane to accommodate more water.
→ Loss of microvilli.
→ Formation of cellular organelle like endoplasmic reticulum. These are composed of phospholipids.
→Myelin figures are intracellular whorls of laminated lipid material.
When these myelin figures are present in membrane-bound structure, containing lysosome enzymes, these are known as myeloid bodies. | Pathology | null |

| single | Five basic mechanisms of transmembrane signaling are well understood. Each uses a different strategy to circumvent the barrier posed by the lipid bilayer of the plasma membrane. These strategies use: a lipid-soluble ligand that crosses the membrane and acts on an intracellular receptor. a transmembrane receptor protein whose intracellular enzymatic activity is allosterically regulated by a ligand that binds to a site on the protein's extracellular domain. a transmembrane receptor that binds and stimulates a protein tyrosine kinase. a ligand gated transmembrane ion channel that can be induced to open or close by the binding of a ligand. a transmembrane receptor protein that stimulates a GTP-binding signal transducer protein (G protein), which in turn modulates production of an intracellular second messenger. Known transmembrane signaling mechanisms:1: A lipid-soluble chemical signal crosses the plasma membrane and acts on an intracellular receptor (which may be an enzyme or a regulator of gene transcription); 2: the signal binds to the extracellular domain of a transmembrane protein, thereby activating an enzymatic activity of its cytoplasmic domain; 3: the signal binds to the extracellular domain of a transmembrane receptor bound to a separate protein tyrosine kinase, which it activates; 4: the signal binds to and directly regulates the opening of an ion channel; 5: the signal binds to a cell-s urface receptor linked to an effector enzyme by a G protein.

d02a62d3-231a-4572-af84-a9f649fd0089 | A 26 year old female patient complains of discoloured teeth. Intra-oral examination reveals generalized intrinsic tetracycline stains. Which of the following is an effective and esthetic treatment in this case? | External bleaching | Intracoronal bleaching | Veneers | Full coverage crowns | 3d
| single | Bleaching tetracycline-stained teeth is difficult, some clinicians advocate intentional endodontic therapy along with the use of an intracoronal nonvital bleaching technique to overcome this problem. Although the esthetic result appears much better than that obtained from external bleaching, this approach involves all the inherent risks otherwise associated with endodontic treatment. External bleaching techniques offer a safer alternative, although they may not be as rapid or effective.
Patients who have darkly stained teeth always should be informed that although porcelain (or composite) veneers can result in improved esthetics, they may not entirely eliminate or mask extremely dark stains. Because of the limited thickness of the veneers and the absolute necessity of incorporating intrinsic opacity, the realistic translucency or esthetic vitality of veneered teeth may never be comparable with that of natural, unaffected teeth. Full porcelain coverage with all-ceramic crowns may be indicated in some patients with severe discoloration because of the crown’s greater capacity to restore esthetic vitality.

| multi | Intestinal amoebiasis - amoebic dysentery Most amoebic infections are asymptomatic. The incubation period of amoebiasis ranges from 2 weeks to many years, followed by a chronic course with abdominal pains and two or more unformed stools a day. Offensive diarrhoea, alternating with constipation, and blood or mucus in the stool are common. There may be abdominal pain, especially in the right lower quadrant (which may mimic acute appendicitis). A dysenteric presentation with passage of blood, simulating bacillary dysentery or ulcerative colitis, occurs paicularly in older people, in the puerperium and with super-added pyogenic infection of the ulcers. Amoebic liver abscess The abscess is usually found in the right hepatic lobe. There may not be associated diarrhoea. Early symptoms may be only local discomfo and malaise; later, a swinging temperature and sweating may develop, usually without marked systemic symptoms or signs. An enlarged, tender liver, cough and pain in the right shoulder are characteristic but symptoms may remain vague and signs minimal. A large abscess may penetrate the diaphragm, rupturing into the lung, and may be coughed up through a hepatobronchial fistula. Rupture into the pleural or peritoneal cavity, or rupture of a left lobe abscess in the pericardial sac, is less common but more serious. Ref Davidson edition23rd pg 287 | Medicine | G.I.T |

Prevent pregnancy for a minimum of 6 months using hormonal contraception.2. Monitor serum hCG levels every 2 weeks. Serial measurement of serum hCG is important to detect trophoblastic neoplasia, and even small amounts of trophoblastic tissue can be detected by the assay. These levels should progressively fall to an undetectable level.3. Chemotherapy is not indicated as long as these serum levels continue to regress.4. Once the hCG level falls to a normal level, test the patient monthly for 6 months; then follow-up is discontinued and pregnancy allowed. | Radiology | Obstetrics And Gynaecology |

| multi | Method of application of neutral sodium fluoride according to Knutson's technique-
If the sodium fluoride reagent is pure and uncontaminated, this solution has a pH of 7. Treatments are given in a series of four appointments.
At the initial appointment, the teeth are first cleaned with aqueous pumice slurry and then isolated with cotton rolls and dried with compressed air. Teeth can either be isolated by quadrant or by half mouth.
Using cotton-tipped applicator sticks, the 2% sodium fluoride solution is painted on the air-dried teeth so that all surfaces are visibly wet. Then with the teeth still isolated, the solution is allowed to dry for 3 to 4 minutes.
This procedure is repeated for each of the isolated segments until all of the teeth are treated.
A second, third and fourth fluoride application, each not preceded by a prophylaxis, is scheduled at intervals of approximately one week.
The four-visit procedure is recommended for ages 3, 7, 11 and 13 years, coinciding with the eruption of different groups of primary and permanent teeth. Thus, most of the teeth would be treated soon after their eruption, maximizing the protection afforded by topical application. | Dental | null |
e530aeef-ed12-4384-ae0d-9e178feb8c1c | Disadvantage of radioactive iodine include the following except: | Hypothyroidism | High chances of relapse | Delayed therapeutic effect | Development of thyroid carcinoma | 1b
| multi | Radioactive iodine emits beta particles that destroy some thyroid tissue and impair the ability of the remaining follicles to replicate; hence once the patient becomes euthyroid, chances of relapse are negligible. Though the amount of radioactive iodine to be administered is estimated by the size of the gland and its iodine uptake, about 40-60% of the patients may develop hypothyroidism. The beneficial effects take 3-4 weeks to become apparent. Neoplasms of the thyroid have been reported in children following treatment with it. | Pharmacology | null |

| single | Keratoconus (conical cornea) is a noninflammatory bilateral (85%) ecstatic condition of the cornea in its axial pa. It usually stas at pubey and progresses slowly. Keratoconus may be associated with :Ocular conditions e.g. ectopia lentis, congenital cataract, aniridia, retinitis pigmentosa, and vernal keratoconjunctivitis (VKC). Systemic conditions e.g., Marfan's syndrome, atopy, Down's syndrome, Ehlers-Danlossyndrome, osteogenesis imperfecta, and mitral valve prolapse. Treatment. Falling vision may not be corrected by glasses due to irregular astigmatism. Contact lenses (rigid gas permeable) usually improve the vision in early cases. In later stages penetrating keratoplasty may be required. Intacs, the intracorneal ring segments, are repoed to be useful in early cases. Keratoconus can occur in patients with vernal keratoconjunctivitis due to repeated rubbing of the eye. early complications: This constant damage to the cornea may cause severe complications, including shield ulcers and vernal plaques, keratoconus, corneal scarring, microbial keratitis, and limbal epithelial stem cell deficiency. As some of these complications occur during the first decade of life, they may result in amblyopia. Ref khurana 16th edition pg 256 Ref: Khurana; 4th ed; Pg 119 | Ophthalmology | Conjunctiva |
