| single | PRESBYCUSIS Sensorineural hearing loss associated with physiological aging process in the ear is called presbycusis. It usually manifests at the age of 65 years but may do so early if there is hereditary predisposition, chronic noise exposure or generalized vascular disease. Four pathological types of presbycusis have been identified. 1. Sensory. This is characterized by degeneration of the organ of Coi, staing at the basal coil and progressing gradually to the apex. Higher frequencies are affected but speech discrimination remains good. 2. Neural. This is characterized by degeneration of the cells of spiral ganglion, staing at the basal coil and progressing to the apex. Neurons of higher auditory pathways may also be affected. This manifests with high tone loss but speech discrimination is poor and out of propoion to the pure tone loss. 3. Strial or metabolic. This is characterized by atrophy of stria vascularis in all turns of cochlea. In this, the physical and chemical processes of energy production are affected. It runs in families. Audiogram is flat but speech discrimination is good. 4. Cochlear conductive. This is due to stiffening of the basilar membrane thus affecting its movements. Audiogram is sloping type. Patients of presbycusis have great difficulty in hearing in the presence of background noise though they may hear well in quiet surroundings. They may complain of speechbeing heard but not understood. Recruitment phenomenon is positive and all the sounds suddenly become intolerable when volume is raised. Tinnitus is another bothersome problem and in some it is the only complaint. Patients of presbycusis can be helped by a hearing aid. They should also have lessons in speech reading through Visual cues. Cuailment of smoking and stimulants like tea and coffee may help to decrease tinnitus.

| multi | The breast becomes fully differentiated during pregnancy and lactation. The terminal lobular units are most affected during this physiologic state. Several histologic changes occur in the terminal ducts and lobules with enlargement and formation of new lobular units early in pregnancy. By the end of the second trimester secretory changes are well developed and the cuboidal luminal epithelial cells show evidence of vacuolization. Accumulation of fat droplets occurs within the cytoplasm of the epithelium of the lobules during the third trimester. The lobules undergo striking hyperplasia to occupy most of the breast parenchyma during this time, with a decrease in the interlobular connective tissue. At term the expanded lobular units show marked distention of their lumina by colostrum. Ref: Cunningham F.G., Leveno K.J., Bloom S.L., Hauth J.C., Rouse D.J., Spong C.Y. (2010). Chapter 5.

| multi | LEPROMIN TEST The test is performed by injecting intradermally 0.1 ml of lepromin into the inner aspect of the forearm of the individual. As a routine, the reaction is read at 48 hours and 21 days. Two types of positive reactions have been described: (a) EARLY REACTION : The early reaction is also known as Fernandez reaction. An inflammatory response develops within 24 to 48 hours and this tends to disappear after 3 to 4 days. It is evidenced by redness and induration at the site of inoculation. If the diameter of the red area is more than 10 mm at the end of 48 hours, the test is considered positive. The early positive reaction indicates whether or not a person has been previously sensitized by exposure to and infection by the leprosy bacilli. In this sense, the early reaction is much superior to the late reactfon. The early reaction has been described as delayed hypersensitivity reaction to "soluble" constituents of the leprosy bacilli. The reaction corresponds to the Mantoux reaction in tuberculosis, caused by the soluble antigens (PPD) of the tubercle bacilli. (b) LATE REACTION : This is the classical Mitsuda reaction. The reaction develops late, becomes apparent in 7-10 days following the injection and reaching its maximum in 3 or 4 weeks. The test is read at 21 days. At the end of 21 days, if there is a nodule more than 5 mm in diameter at the site of inoculation, the reaction is said to be positive. The nodule may even ulcerate and heal with scarring if the antigen is crude. It may be noted that the diameter of the red area in the early reaction, and the diameter of the nodule in the late reaction are measured. The early reaction is induced by the soluble constituents of the leprosy bacilli; and the late reaction by the bacillary component of the antigen. It indicates cell-mediated immunity. In the first 6 months of life, most children are lepromin negative; some may become positive by the end of first year. Data obtained from different pas of the world indicate that in endemic areas, lepromin reaction is already positive in 20 per cent of children under 5 years of age, and this propoion increases to around 60 per cent or more in the 10-14 years age group, and to 80 per cent or more in persons over 19 years of age. BCG vaccination is capable of conveing the lepra reaction from negative to positive in a large propoion of individuals. Value of the lepromin test Lepromin test is not a diagnostic test. The two drawbacks that stand in the way of this test being used for diagnosis are : (i) positive results in non-cases, and (ii) negative results in lepromatous and near-lepromatous cases. The test has been generally accepted as a useful tool in evaluating the immune status (CMI) of leprosy patients. It is of considerable value in confirming the results ofclassification of cases of leprosy on clinical and bacteriological grounds. In other words, the test is widely used as an aid to classify the type of disease. The test is also of great value in estimating the prognosis in cases of leprosy of all types. The test is usually strongly positive in the typical tuberculoid cases, and the positivity getting weaker as one passes through the spectrum to the lepromatous end, the typical lepromatous cases being lepromin negative indicating a failure of CMI. It is known that lepromin negative individuals are at a higher risk of developing progressive multibacillary leprosy, but those who are lepromin positive either escape the clinical disease (the majority) or develop paucibacillary disease (the minority).

| multi | Trans fatty acids (TFA) are atherogenic. They lower HDL level and elevate LDL level. TFA is present in dairy products and hydrogenated edible oils. It is widely used in the food industry since it increases the shelf life of fried food. Cooking media containing PUFA and fast food preparations have a high content of trans fatty acids. Trans fatty acids adversely affect endothelial function and aggravate insulin resistance and diabetes.

| single | Clinical features of Peptic ulcers Peptic ulcer disease is a chronic condition with spontaneous relapses and remissions lasting for decades, if not for life. The most common presentation is with recurrent abdominal pain that has three notable characteristics: localisation to the epigastrium, relationship to food and episodic occurrence. Occasional vomiting occurs in about 40% of ulcer subjects; persistent daily vomiting suggests gastric outlet obstruction. In one-third, the history is less characteristic, especially in elderly people or those taking NSAIDs. In this situation, pain may be absent or so slight that it is experienced only as a vague sense of epigastric unease. Occasionally, the only symptoms are anorexia and nausea, or early satiety after meals. In some patients, the ulcer is completely 'silent', presenting for the first time with anaemia from chronic undetected blood loss, as abrupt haematemesis or as acute perforation; in others, there is recurrent acute bleeding without ulcer pain. The diagnostic value of individual symptoms for peptic ulcer disease is poor; the history is therefore a poor predictor of the presence of an ulcer.

Healing by primary intention It occurs in wounds with opposed edges, e.g., surgical incision.The healing process follows a series of sequantial steps : ?Immediate after incision Incisional space filled with blood containing .fibrin and blood cells.Dehydration of the surface clot forms scab that covers the wound.Within 24 hours Neutrophils appear at the margins of wound.In 24-48 hoursEpithelial cells move from the wound edges along the cut margin of dermis, depositing basement membrane components as they move.They fuse in the midline beneath the surface scab, producing a continuous but thin epithelium layer that closes the wound.By day 3Neutrophils are largely replaced by macrophages.Granulation tissue progressively invades the incision space.Collegen fibers now present in the margin but do not bridge the incision.By day 5Incisional space is largely filled with granulation tissue.Neovascularization is maximum.Collegen fibrils become more abundant and begin to bridge the incision.The epidermis recovers its normal thickness.During second weekLeukocytes and edema have disappeared.There is continued accumulation of collegen and proliferation of fibroblast.By the end offirst month Scar is made up of a cellular connective tissue devoid of inflammatory infiltrate covered now by intact epidermis.B. Healing by secondary intention It occurs in wounds with seperated edges in which there is more extensive loss of cells and tissue.Regeneration of parenchymal cells cannot completely restore the original architecture, and hence abundant granulation tissue grows.Healingby secondary from primary intention in several respects : Inflammatory reaction is more intense.Much larger amounts of granulation tissue are formed.Wound contraction occurs - Feature that most clearly differentiate secondary from primary healing.Permanent wound contraction requires the action of myolifibroblasts - Fibroblasts that have the ultrastructural characteristic of smooth muscle cells. | Pathology | null |

| single | The oral cavity offers a range of different niches (mucosa, tongue, tonsils, saliva and teeth, etc.) where the bacteria can adhere and survive. The transmission of bacteria from one niche to another is likely to occur.
If this transmissions occurs at high speed (nothing but translocation), it could jeopardize the outcome of periodontal therapy (because of reinfection). This can be prevented by 'One-stage Full mouth disinfection', which is nothing but scaling and root planning of all pockets in 2 visits within 24 hrs, in combination with tongue brushing with 1% chlorhexidine gel for 1 min, mouth rinsing with 0.2% chlorhexidine solution for 2 mins and subgingival irrigation of all pockets with 1% chlorhexidine gel.

| single | Ref Robbins 9/e p218 Systemic lupus erythematosus (SLE) is a multisystem auto- immune disease of protean manifestations and variable clinical behavior. Clinically, it is an unpredictable, remit- ting and relapsing disease of acute or insidious onset that may involve viually any organ in the body; however, it affects principally the skin, kidneys, serosal membranes, joints, and hea. Immunologically, the disease is associ- ated with an enormous array of autoantibodies, classically including antinuclear antibodies (ANAs). The clinical pre- sentation of SLE is so variable, with so many overlapping features with those of other autoimmune diseases (RA, polymyositis, and others), that it has been necessary to develop diagnostic criteria for SLE (Table 4-9). The diag- nosis is established by demonstration of four or more of the criteria during any interval of observation. Hematoxylin bodies are seen these are deposition of antigen antibody complexes in various tissues | Anatomy | General anatomy |

| single | Ans. b (2 to 6%). (Ref. Nelson, Textbook of Paediatrics, 18th/pg. 1878)Congenital heart disease occurs in# 0.5 to 0.8% of live births.# 3 to 4 % of stillboms.# 10 to 25% of abortuses.# 2% of premature infants (except PDA)# 0.8% of normal population.# 2-6% after birth of a child with CHD or if parent affected.# 20-30% when 2 first-degree relatives have congenital heart disease.NOTE: Most congenital defects are well tolerated in the fetus because of the parallel nature of the fetal circulation. Even the most severe cardiac defects (hypoplastic left heart syndrome) can usually be well compensated for by the fetal circulation. It is only after birth when the fetal pathways (ductus arteriosus and foramen ovale) are closed that the full hemodynamic impact of an anatomic abnormality becomes apparent. One notable exception is the case of severe regurgitant lesions, most commonly of the tricuspid valve. In these lesions (Ebstein anomaly), the parallel fetal circulation cannot compensate for the volume load imposed on the right side of the heart. In utero heart failure, often with fetal pleural and pericardial effusions, and generalized ascites (nonimmune hydrops fetalis) may occur. | Pediatrics | C.V.S. |
