Cholelithiasis in sickle cell disease in India.

Eighty cases (63 Males and 17 Females) of sickle cell disease were searched for gall stone by ultrasonography, 8 (10%) cases had gall stone. Gall stones were more common in males (11.1%) than females (5.8%). It was not found below 13 years of age. Three cases had single and five cases had multiple gall stones. Three of them had thickened gall bladder wall. Typical biliary colic was uncommon (1 case). There was no case of obstructive jaundice. HbF% level was significantly lower in cases with gall stone (12.31 +/- 3.95) than without gall stones (16.73 +/- 6.30). Episodes of aggravated anaemia and total serum bilirubin was significantly higher (1.27/pt and 4.12 +/- 1.34 mg%) in cases with gall stone than without gall stone (0.31/pt and 2.74 +/- 1.47 mg%). The above findings suggest association of greater degree of haemolysis with formation of gall stone in sickle cell disease cases.

Serum immunoglobulins in sickle cell disease.

Immunoglobulins IgG, IgA and IgM were estimated in 20 cases of sickle cell disease in steady state, eleven cases of sickle cell disease in crisis and/or infection, 20 cases of sickle cell trait and 14 normal healthy controls. Immunoglobulin deficiency has not been observed in sickle cell disease. Significantly raised IgG but normal IgA and IgM found in sickle cell disease cases was probably due to chronic stimulation of reticuloendothelial cells secondary to chronic hemolysis. IgM levels were significantly higher in patients with splenic enlargement > 3 cm. There was no alteration in immunoglobulin levels in sickle cell trait.

Coagulation disorder following viper bite in Orissa.

Forty-three cases of viper bite were studied for coagulation disorder of which 34 (79.1%) cases had bleeding manifestations from one or more sites, haematuria being the commonest (46.5%). Disseminated intravascular coagulation was the predominant coagulation abnormality. Administration of snake venom antiserum resulted in prompt recovery from coagulation disorder. However, natural recovery from coagulation abnormality did occur though took longer time.

Double blind clinical trial on centperazine & DEC in bancroftian filariasis.

Centperazine, an analogue of DEC, was subjected to a double blind controlled trial, to evaluate its efficacy as a newer antifilarial agent. Centperazine (300 mg/day) along with equivalent quantities of DEC and placebo were administered to different types of filariasis patients. DEC was found to be significantly effective in reducing peripheral microfilaraemia, in different weeks and months of follow-up, except at the end of 6th month, as compared to Centperazine. There was no significant difference between the placebo and Centperazine treated patients, in this respect, revealing that the drugs had no efficacy in eliminating peripheral microfilaraemia. Recurrence of acute attack within 6 months was nearly equal with both Centperazine and DEC, being 28.2 and 24 per cent respectively, whereas in the placebo group the recurrence rate was 48.9 per cent. Centperazine treated patients showed significantly less side effects (8.9%), as compared to DEC treated patients (34%). Giddiness, nausea and vomiting were the common adverse effects observed.

Detection of a new focus of Brugia malayi infection in Orissa.

526 people were surveyed in a village called Chudamani, in Balasore district of Orissa, for detection of asymptomatic microfilaria (mf) carriers. Of these 36 (6.8 per cent) were cases found to harbour mf; 19 cases had Brugia malayi, 4 Wuchereria bancrofti and 5 cases had mixed infection. In 8 cases, species could not be ascertained. For the first time after 1955, a focus of B. malayi has been detected in Orissa.
