Malaria still a threat to life--a postmortem study.

This study is of 25 cases of acute malaria encountered at autopsy. Cause of death was malaria in all the cases. The study covers a period of 6 years i.e. from January 1994 to December 1999. There was an upward trend in deaths due to malaria. P. falciparum malaria with its complications accounted for majority of deaths and cerebral malaria (CM) topped the list. Other complications observed were adult respiratory distress syndrome (ARDS), acute septicemic malaria, acute renal failure (ARF) and disseminated intravascular coagulation (DIC). The commonest presenting symptoms were fever with chills associated with central nervous system (CNS) complaints like altered sensorium and unconsciousness.

Entomopthoromycosis--report of four cases.

Entomopthoromycosis is a rare subcutaneous infection and manifests in two clinically distinct forms. Subcutaneous zygomycosis which manifests as a painless nodule on the trunk or the extremities and rhinofacial zygomycosis which is a locally progressive infection of the nasal cavity, paranasal sinuses and soft tissues of the face. Neither of these two forms occur in patients with underlying disease or defective immunity. Here we report four cases of entomopthoromycosis.

Niemann Pick disease--a case report.

Niemann Pick disease is a rare disorder occuring in paediatric age group. The clinical features, hematological characteristics and autopsy findings in an one year old male diagnosed to have Niemann Pick disease are presented.

Amyloid (spheroid) deposits in pituitary adenoma presenting as Cushing disease--a case report.

A rare case of pituitary adenoma with spheroid amyloid deposits encountered in a 40 year old male is presented.

Blood transfusion associated fatalities.

16 post transfusion deaths were studied by reviewing clinical and blood bank records and by postmortem examination whenever possible. 13 of these cases belonged to regional blood bank, 2 were transfused in other hospitals and referred for management of transfusion reactions and one case be longed to other blood bank in the city. 3 deaths could not be attributed to transfusion reaction. Post transfusion endotoxaemia (7 cases) was the most frequent mode of transfusion associated fatality followed by cardiac overload (5 cases) and septicaemia (3 cases). In two cases endotoxaemia coexisted with cardiac overload. The pretransfusion compromised clinical course unfavourably thereby contributing significantly in death. The 3 clinically stable patients succumbed to posttransfusion endotoxaemia. The incidence of transfusion associated fatality in the present institute was 0.028% amongst total transfusions.

Study of systemic fungal infections in autopsy material.

A retrospective study of 2526 autopsy cases was done in order to find out the pattern of systemic fungal infections. The autopsy records were reviewed for case histories, gross and histological findings. The histological sections from cases showing evidence of fungalo infections were reviewed. The fungal infections were found in 28 cases. Of these 11 (93.29 percent) were aspergillosis, 8 (28.27 percent) were mucormyosis, 6 (21.43 percent) were monilial infections and 3 (10.71 percent) were monilial infections and 3 (10.71 percent) were cryptococcosis. The incidence of systemic fungal infection was 1.11 percent. The most common type of fungal infection was aspergillosis. The maximum number of fungal infection was seen in the respiratory system. The fungal infections presented as opportunistic infections in all but one case. The metabolic disturbance was the most frequent predisposing condition for systemic fungal infections.

Effect of 'Arogyavardhini' against carbon tetrachloride induced hepatic damage in albino rats.

'Arogyavardhini'-an indigenous formulation was evaluated for its hepatoprotective activity in rats, using two models of carbon tetrachloride (CCl4) hepatic damage, one simulating vital hepatitis and the other simulating fatty change. The protective effect was assessed from serum aspartate transaminase (AST) and alkaline phosphatase levels and from histopathological changes in liver. The results revealed that 'Arogyavardhini' (5 mg/100g, PO daily) was effective in minimizing the changes in serum levels of AST and alkaline phosphatase induced by CCI. The protective effect was also evident on histopathological examination.

Altered sensitivity to acetylcholine during chronic administration of organophosphorus anticholinesterase (fenthion) in albino mice.

Tissue sensitivity to acetylcholine during chronic administration of fenthion was assessed in mice. Fenthion was injected intra-muscularly every fourth day and experiments were carried out at various intervals. The parameters selected for testing cholinergic effects were, acetyl choline-induced contraction of isolated ileum and salivary secretion in vivo. In both types of experiments an initial supersensitivity followed by tolerance to acetylcholine were observed. The underlying mechanisms are discussed.
