RESUMO
Pleomorphic adenoma of major salivary gland like parotid is most common and generally it affect the superficial lobe of the gland. It sometime affect the minor salivary gland of different structure of face. It is rarely seen in minor salivary gland of the hard and soft palate . Surgery with negative margins does not lead to recurrence. We have encountered a pleomorphic adenoma of minor salivary gland of posterior part of hard palate in young female patient and it was excised with definitive margin with no recurrence. The defect was left to granulate of itself uneventfully.
RESUMO
This study compares water quality parameters, shrimp growth and mortality rates, and biomass at harvest in two ponds of equal size, seeded with the same density (7 m-2) of White Spot Syndrome Virus (WSSV) and Monodon Baculo Virus (MBV) negative post-larvae (PL)-20 of shrimp, Penaeus monodon in the Vellar estuary of South India. The primary difference between the ponds was the water source; one was filled from the estuary and the second with water from bore wells with high alkalinity. Temperature in both ponds was similar and reached 32oC after 185 days of culture. Dissolved oxygen (DO) levels were within the acceptable range although levels in the alkaline pond were near the lower limit for the last 90 days before harvest. Salinity levels were similar in both ponds, above optimal levels, and increased over the 185 days. Alkalinity in the estuarine water was typically < 50 ppm and again 200-320 ppm in the alkaline pond. In the alkaline pond, beginning on the 75th day mineral deposits was observed covering all parts of the shrimp including the eye and the inner gill chambers, and by harvest, 42% of the shrimp showed this coating. Elemental analysis identified the major constituents as calcium, phosphorus and manganese. Survival rates in the estuarine-water-fed pond was 92% with a total pond biomass at harvest of 1.65 tons ha-1 compared to survival of 79% in the alkaline pond and a biomass at harvest of 1.020 tons ha-1. When well water must be used, its alkalinity should be monitored and diluted with water from other sources.
RESUMO
Background: The use of computers is increasing among medical students, therefore we carried out a cross sectional study in Mangalore, India, with the objective of assessing the pattern of computer and Internet use among both undergraduate and postgraduate medical students. Methods: A total of 500 medical students from 4 different medical colleges in Mangalore participated in the study. 400 were undergraduates and 100 were postgraduates / interns. A pre-tested semi-structured questionnaire was used to collect data and data analysis was done using SPSS Version 11. Results: The majority of students who participated in the study were from the age group 19-21years constituting 34.6%. The computer was used for entertainment mainly by the 1st and 2nd year medical students (69.5%) whereas 40% PG / Interns use it for general information and 31% for research activities. Majority of the PG/Interns (77%) were satisfied with computer assisted teaching while 20% 1st and 2nd year students were not. Majority of 1st and 2nd year medical students (50.5%) use Internet most often to communicate socially while 21% Pre final and final year students use Internet most often to engage in work for classes. The use of E-mail was the most popular of Internet services used by 87% PG/Interns. Conclusion: A significant relationship was demonstrated between the year of study and the purpose of computer/Internet use. As the students progress through their curriculum the use of computer for entertainment is declining and use for general information and thesis / research work is rising.
RESUMO
Drug eluting stents have made a significant impact on restenosis. However, there are concerns regarding delayed "catch-up" of restenosis. In this case report we present two such patients with delayed occurrence of restenosis after drug eluting stent implantation.
