Oocyte retrieval and histological studies of follicular population in buffalo ovaries.

Ovaries (N = 250) from slaughtered buffaloes were collected to study follicular population and compare methods of oocyte retrieval. The number and size of surface follicles were recorded and grouped into different categories. Different sized follicles in relation to oocyte diameter were studied histologically. Yield of oocytes per ovary were less (P < 0.05) from ovaries bearing a corpus luteum (CL). Techniques used for oocyte recovery included slicing, follicle puncture and aspiration. The oocyte recovery rate was greatest (P < 0.05) using slicing. The average number of visible surface follicles was 5.20 +/- 0.97 with mean numbers of 2.5, 1.2, 0.82 and 0.62 per ovary for follicles sized 4, 8, 12 and 12mm respectively. Histological studies revealed large numbers of primordial follicles in prepubertal and atretic follicles in senile buffaloes. They also established a biphasic relationship of growth between oocyte diameter and follicular size.

Anterior fontanel size.

Anterior fontanel size was determined in a cross-sectional study of 445 infants ranging in age from newborn period to 2 years. The mean anterior fontanel size in neonates was 3.37 +/- 0.61 cm which decreased to 0.37 +/- 0.06 cm in 24 months age group. The age of closure of anterior fontanel was 12, 18 and 24 months in 40%, 70.4% and 91.3%, respectively.

Modified Levinson's test in rapid diagnosis of tuberculous meningitis.

Modified Levinson's precipitation test was done in 64 cases of TBM, 54 cases of TBM with inconsistent CSF finding, and 32 cases of pyogenic meningitis. The test was positive in 93.7% cases of TBM (sensitivity, 93.7%), 85.5% cases of TBM with doubtful diagnosis and in 9.4% cases of pyogenic meningitis (specificity 90.6%) compared to 79.7%, 72.2% and 18.8% in original Levinson's test, respectively. With CSF examination only 66% cases of TBM could be diagnosed while with modified Levinson's test and CSF analysis 89% cases could be diagnosed (p < 0.001). So modified Levinson's test for diagnosis of TBM is better than Levinson's test (p < 0.05) with an added advantage of time saving.

Poliomyelitis with special reference to immunization status.

One hundred ninety one children below 5 years of age suffering from poliomyelitis were analyzed to find out the immunization status and its correlation with the incidence of poliomyelitis. Effects of age, sex, immunization status and seasonal variation on the morbidity and mortality status were studied. The maximum number of cases were admitted during the months of July (23.6%) and August (23.1%). Of 191 cases, 143 (74.9%) had no immunization and 48 (25.1%) were partially immunized. A total of 155 (81.2%) cases had spinal polio, 23 (12.01%) bulbo-spinal polio, and 13 had (6.8%) bulbar polio. Serious illness (bulbospinal and bulbar type) was more in partially immunized children (25%) as compared to unimmunized children (16.8%). The mortality rate was more than two times higher in the partially immunized (29.6%) as compared to unimmunized children (11.2%). The possible explanation for high mortality in partially immunized children could be due to the adverse effect of OPV which has not been studied so far.

Prothrombin time in first week of life with special reference to vitamin K administration.

Prothrombin time was estimated in 100 neonates (80 full term and 20 preterm). Among the full term infants 50 were healthy and 30 sick. Prothrombin time was altered in neonates with birth hypoxia and prematurity (p less than 0.001). Vitamin K administration to anoxic babies resulted in improvement in prothrombin time after 48-72 hours (p less than 0.001). Four newborns has bleeding, 2 had anoxia and 2 were only in preterms who did not receive vitamin K after birth. It is concluded that vitamin K should be given to all preterms and those with difficult deliveries; term, healthy newborns do not need it.

Blunt renal injury--an experience of 30 cases.

Thirty cases of blunt renal injury are reviewed. The need for rapid and accurate diagnosis of these cases with excretory urography, supplemented in certain patients with renal angiography, is discussed. High-dose excretory urography allows the cases to be categorized into minor or major injuries. All minor injuries can be managed without operation. For major injuries, a conservative approach, if necessary followed by surgical exploration, avoids loss of organ in most of the cases.

Urodiagrams: a new method of uroflow pattern analysis.

Uroflow diagrams, obtained by plotting the mean flow rate at 1-second intervals for controls and patients with bladder outflow obstruction, have been studied in 60 healthy controls and 100 patients. Standard patterns were obtained for male and female controls in 3 different age groups and for patients with various types of lower urinary tract obstruction. Outflow diagrams in age and sex-matched controls were compared to those obtained from patients, indicating the nature and the site of obstruction.
