The most constant and most important BAEP waves from the clinical point of view are waves I, III & V. Their measurements include absolute latency and interpeak latency. The Interpeak latencies represent conduction time through relay stations of auditory pathway in the brainstem. Thus IPL I-III is a measure of conduction from acoustic nerve to pontomedullary region, III-V conduction in the more rostral pontine and midbrain portion of the pathway and I-V reflects the total brainstem conduction time. Concerning electrophysiological measures, it appears that at least for middle and late evoked potentials male and female differences appear in adulthood. There appears to be less agreement among researchers with respect to the age at which gender differences are evident with the auditory brainstem response. The aim of our study is to find out the effect of gender on BAEP waves latencies and amplitudes. We assigned one hundred and five subjects for study. Out of them 55 were males and 50 females between the age group of 20-35 years. Wave III and wave V latencies & I-III and I-V interpeak latencies were significantly (P < 0.01) shorter in females than in males. The difference in mean wave V latency between males & females was 0.18 ms. The significant changes in the BAEPs in our study support the possible role of gender as contributive factors for normal variations.
In India smoking is a common habit in both rural and urban areas . According to national sample survey 35% of men and 12% of women in India use tobacco in some form or other and it causes various effects on body including blood . Evidence is that accumulating haemostatic factors have a pathogenic role in ischemic heart diseases and stroke ,smoking habit is known to affect several haemostatic heart diseases.
In this study 100 healthy male subjects, 50 chronic smokers and 50 non smokers were assessed for differential white blood cell count .there was decreased neutrophil and basophil count while lymphocyte count was significantly increased to about 30% in smokers from about 24% in non smokers ,while there was no significant changes in other white blood cells.
Objectives- 1.To study the effect of tobacco smoking on different white blood cell count.
2.To establish a correlation between chronic tobacco smoking and its effects on parameters which were studied.
3.To create awareness in tobacco smokers about the effect of tobacco on their health.
Opportunistic infections of the gastrointestinal tract have played a critical role in determining symptomatic illness in immuno compromised individuals. In recent years intestinal infections such as Cryptosporidium, Cyclospora and Isospora are becoming more prevalent in acquired immuno deficiency syndrome. Strongyloides stercoralis infections can lead to hyper infection syndrome and found to be lethal in immuno compromised patients the present study was under taken to determine the prevalence of intestinal parasites in HIV sero positive patients. Stool samples from 166 HIV infected patients with diarrhoea and 123 HIV infected patients without diarrhoea were examined for intestinal parasites by microscopy. Intestinal parasites were seen in 69.2% HIV patients with diarrhoea as compare to their presence in 30.08% HIV patients without diarrhoea.
