Nephrotic syndrome in non-cirrhotic portal fibrosis: a report of three cases.

We describe three patients with nephrotic syndrome and non-cirrhotic portal fibrosis. In two of them, the liver disorder preceded the nephrotic syndrome while in the third patient the two conditions presented together. All three patients achieved remission of nephrotic syndrome with prednisolone and cyclophosphamide.

Environmental pollution and chronic arsenicosis in south Calcutta.

Careless handling of industrial wastes often creates problems for human health and the environment. Chronic arsenic toxicity, resulting from household use of arsenic-contaminated water occurred in 53 out of 79 members (67%) of 17 families residing in South Calcutta close to a factory that manufactured Paris-green (copper acetoarsenite). Clinical investigation of 20 of these affected persons showed typical skin pigmentation as well as palmar and plantar keratosis in all of them, while gastrointestinal symptoms, anaemia and signs of liver disease and peripheral neuropathy were seen in many. The water used by the affected families for drinking and cooking had been taken from shallow tubewells and had arsenic levels from 5.0 to 58 mg/l (WHO permissible limit, 0.05 mg/l). Other residents in the same area whose drinking-water came from deep tubewells or from tap water supplied by the Calcutta Municipal Corporation (arsenic levels, less than 0.05 mg/l) were not affected. The study confirms that arsenic in the shallow tubewells was due to the waste discharged by the factory producing Paris-green.

Hepatic lesions caused by excretory and secretory products of Ascaris lumbricoides in golden hamster.

OBJECTIVE: To ascertain the role of excretory and secretory (ES) products of Ascaris lumbricoides in liver damage. METHODS: The ES products of A lumbricoides were collected in vitro and their SDS-PAGE analysis was done. Feeding and subcutaneous injection of ES products were done in hamsters. Estimation of serum proteins, alkaline phosphatase and alanine aminotransferase and histology of liver were carried out. Control animal experiments were done concurrently. RESULTS: The ES products of A lumbricoides contained several proteins ranging in molecular weight from 14 to 205 Kd. Prolonged feeding of ES products caused elevation of ALT and amyloid deposition in the liver, whereas short term feeding or subcutaneous challenge caused focal cell necrosis and granuloma formation in the liver. CONCLUSION: ES products of A lumbricoides can produce liver damage.

Amyloidosis

Symptomatic solitary giant congenital cysts of liver.

Three cases of non-parasitic liver cysts are reported. Each of them presented with upper abdominal pain and enlarged liver, and a cyst of enormous size was detected by ultrasound and isotopic scan. Residual cavity following cyst surgery was obliterated by different surgical techniques.

Abdominal Pain

Immunological status of women with prolonged oral contraceptives and occurrence of giardiasis.

Immunological status of 14 women taking oral contraceptive for prolonged period (more than 6 months, low dose pill) was studied. Phytohaemagglutinin induced lymphocytes stimulation (PILT) was found to be significantly depressed in these subjects though T-lymphocyte subpopulation was found to be normal. Serum IgA and IgG levels in these cases were found to be normal but IgM level was increased. Though incidence of G lamblia infection was reported to be high in immunocompromised subjects, it was found only one out of 14 subjects taking oral contraceptive harboured the protozoa.

Clinical observations on smallpox: a study of 1233 patients admitted to the Infectious Diseases Hospital, Calcutta, during 1973.

The paper presents clinical observations on 1 233 persons with smallpox who were admitted to the Infectious Diseases Hospital, Calcutta, in 1973. The disease was of the modified type in 53 patients (4.3%), the ordinary type in 717 (58.2%), the flat type in 249 (20.2%), and the haemorrhagic type in 214 (17.3%). The fatality of these types of smallpox was found to be 5.7%, 26.8%, 88.4%, and 98.1%, respectively, and the overall case fatality was 50.7%. The haemorrhagic type was found mainly among older patients and affected males more often than females. The vaccination status of 1 218 patients was known. Of these, 901 (73.9%) were unvaccinated and had a fatality rate of 53.4%, whereas the 317 (26.1%) vaccinated patients had a fatality rate of 36.5%. Among the 201 haemorrhagic cases, 145 patients were unvaccinated (16.09% of the total number unvaccinated) and 56 (17.67%) had been vaccinated. Of 34 patients vaccinated during the incubation period, 19 (41.1%) died, whereas of 18 patients who had been vaccinated after the onset of fever, but before the appearance of rash, 9 (50%) died.

Gastric acidity in cholera and noncholera diarrhoea.

Gastric acid production, unstimulated and following stimulation with betazole hydrochloride, was measured in Indian men with cholera or acute vibrio-negative diarrhoea-Measurements were made during acute illness and after different periods of convalescence. Men from the same socioeconomic group and from a higher one served as controls. Stimulated acid production was severely reduced during diarrhoea caused by V. cholerae and related vibrios but not during acute vibrio-negative diarrhoea. Acid production returned to stable convalescent values 1-3 days after cessation of diarrhoea. Stimulated acid production was significantly lower in controls from the lower socioeconomic group than in those from the higher socioeconomic group. Achlorhydria that did not respond to betazole administration occurred in 32% of the convalescent cholera patients but in none of the controls or convalescent vibrio-negative diarrhoea patients. It is concluded from these results that diarrhoea produced by V. cholerae and related vibrios is accompanied by transient inhibition of gastric acid secretion, that cholera occurs largely in a population with impaired acid secretion, and that preexisting achlorhydria may predispose to infection with V. cholerae.
