Background:Hypertension is one of the most common complication during pregnancy. It contributes significantly to maternal and perinatal morbidity and mortality. This study was designed to investigate the morphological and histopathological changes in placenta from pregnancies complicated with hypertension.Objectives:To study the morbid changes in placenta in cases of pregnancy-induced hypertension (PIH) and to correlate the findings with birth weight of new born babies in comparison with normotensive mothers.Materials and Methods:The study was done on 100 placentas, out of which 50 were collected from normotensive mothers and the remaining 50 from PIH cases. All the placentas were studied morphologically and histologically. The birth weight of neonates was recorded.Results:In the present study it was observed that weight and dimensions of placenta was less in study group when compared with control group. The mean neonatal birth weight was more in normal pregnancy and feto-placental weight ratio was significantly high in hypertensive group. Histopathological study showed significant number of syncitial knots, areas of fibrinoid necrosis, hyalinization, calcification, and medial coat proliferation of medium sized blood vessels in hypertensive group.Conclusion:PIH significantly affects the placenta by reducing its weight and dimensions. These changes may cause placental insufficiency as a result of compromised utero-placental blood flow. Therefore has an adverse affect on the neonatal birth weight. PIH has definite influence on morphology, histology of placenta, and thus affects the growth of the fetus.

Context:The distribution of uropathogens and their susceptibility pattern to antibiotics vary regionally and even in the same region, they change over time. Therefore, the knowledge on the frequency of the causative microorganisms and their susceptibility to various antibiotics are necessary for a better therapeutic outcome.Aim:The aim was to study the frequency and distribution of uropathogens and their resistance pattern to antibiotics in a tertiary care hospital.Settings and Design:Retrospective study for a period of 1 year from January 2011 to December 2011 in a tertiary care hospital.Materials and Methods:The culture and sensitivity data of the uropathogens from suspected cases of UTI were collected from the records of Microbiology Department for study period. Midstream urine samples were processed for microscopy and culture, and the organisms were identified by standard methods. Antibiotic susceptibility was carried out by Kirby-Bauer disk diffusion method according to Clinical and Laboratory Standards Institute guidelines. Descriptive statistics were used to analyze the data.Results:Of 896 urine samples, 348 (38.84%) samples were positive for urine culture. Escherichia coli (52.59%) was the most common organism followed by Klebsiella. E. coli was least resistant to imipenem (8%) and amikacin (16%) and was highly resistant to co-trimoxazole (69%) and ampicillin (86%). Klebsiella species were least resistant to amikacin (26%) and were highly resistant to ampicillin (92%). The overall resistance pattern of antibiotics to uropathogens was the highest to nalidixic acid (79%) followed by co-trimoxazole (75%) and ampicillin (72%). Good susceptibility was seen with imipenem and cephalosporins.Conclusion:E. coli is still the most common uropathogen. Nalidixic acid, ampicillin, co-trimoxazole, and first-generation fluoroquinolones have limited value for the treatment of UTI. Sensitivity to imipenem and amikacin are still retained and may be prescribed for complicated UTI. Routine monitoring of drug resistance pattern will help to identify the resistance trends regionally. This will help in the empirical treatment of UTIs to the clinicians.
