Pulmonary infections may be caused by bacteria, fungi, viruses, or mycoplasma. Bacterial infections generally result in a polymorphonuclear (neutrophil) response. Bacterial infection of the lung (pneumonia) results in consolidation of the lung, which may be patchy or diffuse. Patchy consolidation of the lung is seen in bronchopneumonia (lobular pneumonia), while diffuse involvement of an entire lobe is seen in lobar pneumonia. Histologically, bronchopneumonia is characterized by multiple, suppurative neutrophil-rich exudates that fill the bronchi and bronchioles and spill over into the adjacent alveolar spaces. In contrast, lobar pneumonia is characterized by four distinct stages: congestion, red hepatization, gray hepatization, and resolution Reference: Robbins & Cotran Pathologic Basis of Disease, 9edition.

Most tissue adhesives or glue are cyanoacrylate polymers, such as n-butyl-2-cyanoacrylate (eg, Histoacryl®, PeriAcryl®) or 2-octyl cyanoacrylate (eg, Dermabond®, Surgiseal). Cyanoacrylate tissue adhesives are liquid monomers that undergo an exothermic reaction on exposure to moisture (eg, on the skin surface), changing to polymers that form a strong tissue bond. When applied to a laceration, the polymer binds the wound edges together to allow normal healing of the underlying tissue. Compared with wounds closed with sutures, the tensile strength of wounds closed by tissue adhesives is less at the time of initial application, but equalizes by one week post-repair. Advantages: Less painful application, and sometimes no need for local anesthetic injection More rapid application and repair time Cosmetically similar results at 12 months post-repair Waterproof barrier Antimicrobial properties Better acceptance by patients No need for suture removal or follow-up Indications and contraindications: For use of tissue adhesives the wound needs to be clean, dry with near perfect hemostasis and under no tension. Complex stellate lesions or crush injuries should not be closed with tissue adhesives since good wound approximation is difficult to achieve. Tissue adhesives are not recommended for lacerations of the hands, feet, or joints, since repetitive movements could cause the adhesive bond to break before sufficient tensile strength is achieved. Tissue adhesives are not recommended for the oral mucosa or other mucosal surfaces or areas of high moisture such as the axillae and perineum. Lacerations involving the hairline or vermilion border require more precision, and should be repaired with traditional sutures.

Answer is A (Autonomic neuropathy): Hypoglycemic unawareness refers to a loss of warning symptoms that ale individuals to the presence of hypoglycemia and prompt them to eat and'abo the episode. Hypoglycemic unawareness can be attributed to two factors : Autonomic neuropathy Loss of catecholamine response to hypoglycemia : This means that patients with repeated attacks of hypoglycemia lose their capacity to release epinephrine and norepinephrine in response to hypoglycemia. (increase release of glucogon in response to hypoglycemia is lost very early in type I Diabetes Thus type I patients overeated with insulin may be unaware of critically low levels of blood glucose because of an adaptive blunting of their alarm systems owing to repeated episodes of hypoglycemia.

Ans. A: 1-123 The radionuclides that are used in thyroid scans are two isotopes of iodine, 1-131 and 1-123, and an isotope of technetium known as 99m Tc. Technetium scanning is preferred for some diagnostic workups because it is relatively fast and does not require the patient to fast beforehand. Many prefer to reserve 1-131 for follow-up evaluations of cancer patients, and use 1-123 for thyroid uptake tests and routine thyroid scans. The reason for the distinction is the higher radiation burden of 1-131.

Ref: Robbins Pathologic Basis of Disease, 8th edition, Pg: 183Explanation:T Cell-Mediated (Type IV) HypersensitivityThe cell-mediated type of hypersensitivity is initiated by antigen-activated (sensitized T lymphocytes, including CD4+ and CD8+ Tcells.Tubercle bacilli colonizing the lungs are persistent or nondegradable antigensThe perivascular infiltrate is dominated by macrophages over a period of 2 or 3 weeks.The activated macrophages often undergo a morphologic transformation into epithelium-like cells and are then referred to as epithelioid cells.A microscopic aggregation of epithelioid cells, usually surrounded by a collar of lymphocytes, is referred to as a granuloma.This pattern of inflammation, called granulomatous inflammation is typically associated with strong T-cell activation with cytokine production.M. tuberculosis enters macrophages by endocytosis mediated by several macrophage receptors: mannose receptors bind lipoarabino- mannan. a glvcolipid in the bacterial cell wall, and complement receptors bind opsonized mycobacteria.M. tuberculosis organisms replicate within the phagosome by blocking fusion of the phagosome and lysosomeAbout 3 weeks after infection, a T-helper 1 (TH1) response is mounted that activates macrophages to become bactericidal.Differentiation of TH1 cells depends on IL-12, which is produced by antigen-presenting cells that have encountered the mycobacteria.Mature TH1 cells, both in lymph nodes and in the lung, produce IFN-g.INF-g is the critical mediator that enables macrophages to contain the M. tuberculosis infection.IFN-g stimulates formation of the phagolysosome in infected macrophages, exposing the bacteria to an inhospitable acidic environment.Macrophages activated by IFN-y differentiate into the "epithelioid histiocytes" that characterize the granulomatous response, and may fuse to form giant cells.Activated macrophages also secrete TNF. which promotes recruitment of more monocytes.

Haemorrhage is the most frequent life-threatening complication of thyroidectomy. Around 1 in 50 patients will develop a haematoma, and in almost all cases this will develop in the first 24 hours. If an aerial bleed occurs, the tension in the central compament pressure can rise until it exceeds venous pressure. Venous oedema of the larynx can then develop and cause airway obstruction leading to death. If a haematoma develops, clinical staff should know to remove skin sutures in order to release some pressure and seek senior advice immediately. Endotracheal intubation should be used to secure the airway while the haematoma is evacuated and the bleeding point controlled.Ref: Bailey and Love, page no: 815

Temporo-mandibular joint is weight-bearing joint though not covered by hyaline cartilage like sterno-clavicular joint. Clavicle ossifies at five weeks followed by mandible at six weeks. Absence of hyaline cartilage is because no cartilaginous precursor exists at that time. This does not mean that the joint is non-weight bearing, it is the early ossification which has made the joint free of hyaline cartilage.

Koebner response or the isomorphic response, attributed to Heinrich Kobner, is the appearance of skin lesions on lines of trauma. The Koebner phenomenon may result from either a linear exposure or irritation. Pseudokoebner phenomenon-Conditions demonstrating linear lesions after a linear exposure to a causative agent include molluscum contagiosum, was and toxicodendron dermatitis (dermatitis caused by a genus of plants including poison ivy). Was and molluscum contagiosum lesions can be spread in linear patterns by self-scratching ("auto-inoculation"). Toxicodendron dermatitis lesions are often linear from brushing up against the plant. True koebner phenomenon-Causes of the Koebner phenomenon that are secondary to scratching rather than an infective or chemical cause include vitiligo, psoriasis, lichen planus, lichen nitidus, pityriasis rubra pilaris, and keratosis follicularis Ref Harrison 20th edition pg 2111

Ans. a. Met loss of muscle protein due to increased breakdown (Ref: Ganong 24/e p21)Increased levels of alanine in serum after fasting are primarily due to net loss of muscle protein due to increased breakdown."The quantity of carbohydrate normally stored in the entire body can supply the energy required for body functions for 10-12 hours. Therefore, except for the first few hours of starvation, the major effects are progressive depletion of tissue fat and protein. Fat depletion is steady and continues unabated until most of the fat stores in the body are gone. Proteins undergo three phases of depletion-rapid depletion of mobilizable proteins at first, then greatly slowed depletion (during this time increased fat breakdown leads to a state of ketosis), and finally, rapid depletion again shortly before death. The major aim of protein catabolism during a state of starvation is to provide the glucogenic amino acids (especially alanine and glutamine) that serve as substrates for gluconeogenesis in the liver."

Ans. b. Intussusception (Ref; Ghai 8/e p287; Sabiston 19/e p1851; Schwartz 9/e p1433-I434; Bailey 26/e 1184. 1187, 1193. 25/e p1191, 1196. 1198; Shackelford 7/e p1059-106)Most likely diagnosis in a 6 months old child, who woke up in night, crying with abdominal pain, which got relieved on passing red stool, is intussusception.'Intussusception refers to the telescoping of a proximal segment of intestine (intussusceptum) into a distal segment (intussuscipiens). This is a common cause of intestinal obstruction in children between 3 months and 6 years. Most cases occur in infants during the weaning period following introduction of a new food, vaccination or upper respiratory tract infection. The classic triad of abdominal pain, red current jelly stools (blood and mucus) and palpable mass is seen only in a small percentage of children. Ultrasound is the investigation of choice that confirms the diagnosis ('dough nut' sign) and provides information about presence of a mass as lead point. Early reduction either with saline (under ultrasound guidance), barium contrast (both diagnostic and therapeutic) or with air insufflation is advisable. Reduction with air is safer with lower recurrence rates. Failure of radiological reduction or suspected intestinal gangrene may necessitate surgery and resection.'- Ghai 8/e p287IntussusceptionTelescoping of one portion of the intestine into the other.Middle layer is isolated between two sharp bends and first to become gangrenousQ.Highest incidence between 4 and 10 monthsQ of ageApprox. 80-90% of cases occurs between 3 and 36 monthsQ.Mostly idiopathic in infants and toddlersQ (no clear etiology).MC type: IleocolicQEtiology and Predisposing Factors:Upper respiratory tract infections or gastroenteritisQ (adenovirus and rotavirus have been implicated) have been thought to be contributory to the development of 'idiopathic' intussusception. Hypertrophy of Peyer's patchesQ can be seen at surgery, but no single etiologic factor predominates.Approximately 5-10% of cases have a true pathologic lead point. The older the toddler, the more likely there will be a lead pointQ.MC lead point is Meckel's diverticulumQ.Other lead points include polyps, the appendix, intestinal duplication, foreign bodies, and tumors such as hamartomas associated with Peutz-Jeghers syndrome.Henoch-Schonlein purpura: Submucosal hemorrhage acts as a lead pointQ.Cystic fibrosis: Risk for recurrent intussusceptionQClinical Features:Typical history: Sudden, short-duration, cyclic crampy abdominal painQ.During these episodes the infant cries inconsolably with the knees drawn upQ.Between episodes the infant is asymptomaticQ.Vomiting is almost universalQ.Initially the passage of stools may be normal while later on blood mixed with mucus is evacuated- red currant jelly stool.An abdominal mass may be palpated- a sausage shaped abdominal massQ (increase in size and firmness during the paroxysm of pain)There may be an associated feeling of emptiness in the right iliac fossa (Sign of Dance)QOccult or gross blood in 60-90% of cases on rectal examinationQApex may be palpable or even protrude from anus in extensive ileocolic or colocoiic intussusceptionQDiagnosis:USG: Kidney-shaped mass in the longitudinal view or a target sign in the transverse viewHydrostatic reduction by contrast agent or air enema (preferred) is the diagnostic and therapeutic procedure of choiceQ.Successful reduction is confirmed by reflux of airQ (or barium) into the small bowel.Treatment:Hydrostatic reduction by contrast agent or air enema is the diagnostic and therapeutic procedure of choiceQ.The success rate with air or barium reduction should exceed 70%Q.Failure of reduction or the presence of peritonitis mandates operative interventionQ, which can be performed laparoscopically or by a standard approach.Definitive surgical procedure: Ileocolectomy with primary anastomosisQRecurrence:Recurrence after successful hydrostatic reduction is 5-10%, recurrence rate after operative reduction is 1-4%.Recurrence is usually managed by hydrostatic reductionQ.Third recurrenceQ is an indication for operative intervention to look for a lead point.

Light rays from distant objects do not require as much refraction (bending) as do light rays from objects close at hand. Therefore, a thinner lens with less curvature is required for viewing distant objects. The process of accommodation adjusts the thickness of the lens for near and far vision by contracting or relaxing the ciliary muscle that surrounds the lens of the eye; contraction of the ciliary muscle thickens the lens, and relaxation causes the lens to become thinner.

Ans. C: Increased renal blood flow GFR = Kf x Net filtration pressure Net filtration pressure represents the sum of the hydrostatic and colloid osmotic forces that either our/oppose filtration across glomerular capillaries Hydrostatic pressure inside the glomerular capillaries (PGC) - Promotes filtration Hydrostatic pressure in the bowman's capsule outside the capillaries (PB)-opposes filtration Colloid osmotic pressure of glomerular capillary plasma proteins-Opposes filtration Colloid osmotic pressure of Bowman's capsule proteins-promotes filtration - Afferent aeriolar constriction will reduce renal blood flow and reduce PGC, causing a reduction in GFR. - Efferent aeriolar constriction will reduce renal blood flow but increase PGC; these changes act in opposite directions with respect to GFR and the net effect on GFR is minimal. - A reduction in Kf will reduce GFR (contraction of mesangial cells and reducing the area available for filtration) - Any given vasoactive agent may have a spectrum of effects (on afferent/efferent aeriolar tone or Kf), making the net effect on GFR difficult to predict. Thus, angiotensin II, a major regulator of glomerular function, causes constriction of both afferent and efferent aerioles, as well as reducing Kf. The overall outcome for GFR depends on the relative magnitudes of these actions, which vary in different pathophysiological conditions. A high protein intake increase renal blood flow and GFR - Large increase in blood glucose levels in uncontrolled D increase renal blood flow and GFR. Kf: Glomerular ultrafiltration coefficient, PGC: mean hydrostatic pressure in glomerular capillaries

Rapid institution of full nutritional support can cause "refeeding syndrome" in malnourished patients. The hall mark of this condition is hypophosphatemia. Phosphate is taken up by phosphate-depleted cells trying to metabolize the nutrition and levels of ATP fall precipitously. This leads to respiratory failure. Refeeding syndrome can be avoided by starting nutritional support at low levels and increasing slowly. The other substances listed are not associated with respiratory failure after starting nutritional support.
