The most important desideratum of a provisional crown is an adequate marginal fit that is essential for maintaining optimal periodontal health, reducing the sensitivity of freshly prepared dentin and protection of the pulp. The purpose of this in vitro study was to compare the vertical marginal accuracy of provisional crown materials using three different material systems (chemically activated PMMA powder-liquid system, light activated UDMA single paste system, and chemically activated Bis-GMA two paste auto mix system) and two different techniques (direct and indirect). ⋯ This study has shown that provisional crowns fabricated with Bis-GMA composite resin material (two paste auto mix system) registered the best marginal accuracy. Provisional crowns fabricated with indirect technique recorded less marginal opening than with direct technique.

To determine frequency of hepatitis-C in dialysis patients at start of hemodialysis, seroconversion from HCV negative to HCV positive over study duration and factors affecting seroconversion. ⋯ Frequency of HCV seroconversion among chronic hemodialysis patient is found to be 53.37%. Arteriovenous access, number of dialysis, reuse of dialyzer and blood transfusions are important risk factors.

To assess the short- and long-term effects of the adjustable fortification (ADJ) regimen on growth parameters in premature infants and to evaluate the amount of protein supplements given to reach the targeted blood urea nitrogen (BUN) levels. ⋯ A higher protein intake through the ADJ regimen improves the physical growth rate of premature infants in the NICU and after discharge. However, sometimes, the targeted growth and BUN values cannot be achieved despite the administration of protein at the recommended increased doses. Increasing protein supplementation up to 1.6 g/day is safe, feasible, and beneficial for these infants.

To determine the frequency of mycobacterium tuberculosis detection, in bronchial washing in sputum-scarce cases of suspected pulmonary tuberculosis. ⋯ Bronchial washing Gene Xpert has an excellent diagnostic yield for detection of mycobacterium tuberculosis in sputum-scarce cases of suspected pulmonary tuberculosis.

Purpose of this study was to find out frequency of anemia and its causes in newly diagnosed treatment naive lymphoma patients. ⋯ Anemia is a common feature in newly diagnosed lymphoma patients with anemia of chronic disease as the commonest cause. It is more frequent in patients with higher stages of lymphoma especially when bone marrow is involved by lymphoma. Since anemia is an important adverse prognostic factor for the outcome of lymphoma patients, work up for anemia prior to initiation of chemotherapy should be done in every lymphoma patient in order to help improve the management of these patients.
