Studies on the identification and control of pathogen Saprolegnia in selected Indian major carp fingerlings at mid hill altitude.

The Indian major carp cultured in ponds in the North Eastern hilly states of India frequently suffer from fungal disease during winter months resulting in mass mortality. This study examined the pathogenic fungi isolated from farmed raised Indian major carp fingerlings and identified as Saprolegnia. For treatment, the diseased fish were exposed to 4g salt per litre of water for 2 min followed by dip treatment with 5ppm KMnO4 for 10 min, thrice every week for a period of 6 weeks. The treatment resulted in recovery from the disease after 6 weeks from the beginning of treatment. Soon after recovery, the pond management practices such as removal of pond bottom soil, application of lime and replenishment with freshwater were followed in the infected ponds. Our study concluded that rapid decrease in pond water temperature from 22 to 8°C that remains low for months together coupled with increased water pH (9) and decreas dissolved oxygen (4ppm) causes saprolegniasis to the fingerlings of Indian major carps.

Wunderlich's syndrome with hepatic angiomyolipoma in tuberous sclerosis.

We present a patient of tuberous sclerosis complex with bilateral renal angiomyolipoma and hepatic angiomyolipoma with spontaneous retroperitoneal hemorrhage from right angiomyolipoma (Wunderlich's syndrome). Nephron preserving approach was tried but the right kidney could not be salvaged. Hepatic angiomyolipoma was managed conservatively. Wunderlich's syndrome has been found in around 10% of cases of renal angiomyolipomas. Hepatic Angiomyolipoma is a benign mesenchymal neoplasm of the liver which is rarely reported in literature.

Tuberculosis--historical landmarks.

Tuberculosis (TB) since time immemorial has inflicted most miseries in mankind. In ancient times TB was called by many names but the modern one comes from the word 'tubercle'. TB as Pott's disease was widely prevalent among Egyptians in 3700-1000 BC. Hippocrates (460-377 BC) recognised symptomatology of TB. The name tuberculosis was first used by Lanneac and Bayle in early 19th century. Robert Koch in 1882 AD discovered tuberculosis bacillus. Calmette and Guerin laid the foundation BCG vaccination. In 1943, chemotherapy began with the advent of streptomycin (SM) followed by PAS in 1946 and then INH in 1951. Short course chemotherapy results were published in mid 1970s.

Alteration in the activities of the membrane-integrated enzymes of polymorphonuclear leukocytes in obesity.

Oubain sensitive and insensitive adenosine triphosphatase showed decrease in their activities in the polymorphonuclear leukocytes of obese patients while the activity of acetylcholinesterase was found to be increased significantly. The contents of sodium, potassium and magnesium were found to be significantly decreased in polymorphonuclear leukocytes of obese patients. Polymorphonuclear leukocytes obtained from treated obese patients showed considerable restoration.

Fetal outcome and childhood mortality in offspring of mothers with sickle cell trait and disease.

The sickle cell hemoglobinopathy is a major public health problem which causes high morbidity and mortality in India. Although the hematological and clinical profile of the patients is extensively studies. The reproductive outcome of mothers afflicted with sickle cell trait and disease is still unknown in India. In a retrospective study, we have examined the reproductive profile of 190 mothers afflicted with sickle cell, attending Medical Out-Patient Department at V.S.S. Medical College Hospital, Burla in Western Orissa, India during the year 1991-1992. Seventy-three mothers who were found normal after medical examination and were free from hemoglobinopathic disorders, anemia, jaundice, iron deficiency, etc. constituted the control group and 66 mothers with sickle cell trait and 51 with sickle cell disease formed the study group. The reproductive history was recorded for number of conceptions, fate of offspring, live birth, surviving children and childhood mortality. Hematological investigations and hemoglobin electrophoresis were done as per the standard procedure. There was no difference in mean number of livebirths per mother between controls and sickle cell trait mothers. But between the controls and sickle cell homozygotes (p < 0.01), and sickle cell trait and disease (p < 0.01) mothers, this mean number was significant. For abortions/miscarriages, the difference between controls and sickle cell homozygotes (p < 0.001), and sickle cell trait and disease (p < 0.01) mothers was highly significant. The number of stillbirths per mother in homozygous sickle cell mothers was higher (p < 0.01) as compared to controls. There were significantly higher childhood deaths in sickle cell trait (p < 0.05) and disease (p < 0.05) mothers than in the controls. It seems that the sickle cell heterozygote and hemoglobin E heterozygote mothers are genetically better fit than the sickle cell homozygotes. Further, the sickle cell disease is clinically severer than the hemoglobin E disease in India probably due to molecular diversity.

Haematological and coagulation profile in acute falciparum malaria.

The haematological and coagulation profile of 30 cases of acute falciparum malaria were studied. Anaemia, mostly normocytic, normochromic, was observed in 86.7% of cases majority of whom had complications. Severe anaemia (HB < 6gm.) observed in 10% of cases was associated with 100% mortality. Leucocytosis and leucopenia were observed in 13.3% and 6.6% of cases respectively. 90% of cases had thrombocytopenia, the lowest count recorded being 26,000/- cmm. 16.7% of cases had evidence of intravascular coagulation but manifested as generalised bleeding in only one case. Bone marrow aspiration done in 10 cases revealed no abnormality, except for falciparum parasites observed in 2 cases.
