A study of postpill amenorrhea.

Levels of follicle-stimulating hormone, luteinizing hormone and prolactin were evaluated in 52 cases of postpill amenorrhea at the Institute of Post Graduate Medical Education and Research, Calcutta, India. All 52 patients had experienced amenorrhea for one year since discontinuation of oral contraceptive therapy. The incidence of postpill amenorrhea was much higher in patients with histories of oligomenorrhea or irregular menstrual periods. No relationship was seen between the number of cycles of pills used and the incidence of postpill amenorrhea. The ratio of luteinizing hormone to follicle-stimulating hormone in all cases exceeded unity, indicating that postpill amenorrhea is a type of functional secondary amenorrhea.

Sialic acid in human semen.

Sialic acid of seminal fluid of eighty two human subjects has been studied in relation to infertility. Normozoospermic group had highest sialic acid content (94 mgm/100 ml of the fluid) and was significantly different from other groups. The lowest sialic acid level was observed in necrozoospermic group (54 mgm/100 ml of the fluid). Azoospermic (62 mgm/100 ml) and vasectomised group (73 mgm/100 ml) had 33 and 22 percent less sialic acid level respectively than normozoospermic group. For the pooled observation sialic acid was found to be correlated (r = 0.282, significant at 5 percent level) with the total sperm count.

Perinatal mortality in eclampsia in relation to drug therapy.

Fifty-nine babies were born to eclamptic mothers among 7500 deliveries giving incidence of occurrence of 0.77 percent. The perinatal mortality in eclamptic babies was 32.7%, whereas the total perinatal mortality rate amongst all the deliveries was 10.5%. The mothers were treated within Group I--diazepam, Group II i chlorpromazine (largactil), phenargan and diazepam and Group III--largactil, phethidine and phenargan. The mortality rate was 23.8%, 18.8% and 66.6% respectively. The highest number of still-born i.e. six out of 8 occurred in Group III. Hundred percent still-born was noted in 28-32 weeks of gestation and birth weight less than 1.5 kg irrespective of drug regimes. Iargactil potentiates the respiratory depressant effect of pethidine and may cause high rate of still-birth and death after birth.

Value of Mantoux Test in diagnosis of tuberculosis in chronic illness.

Total 240 cases of 2-12 years age group who had contact of tuberculosis indirectly or directly and had chronic illness were screened for tuberculosis. Out of 240 cases, 180 cases were diagnosed as tuberculosis. Special emphasis was given on Mantoux Test (M.T.), though the battery of tests were done to diagnose tuberculosis. Out of 180 cases of Tuberculosis, M.T. was Positive in 97 cases (40.41%) and repeat M.T. was done after 3 weeks and was converted to Positive in 20 cases (8.33%). Thus only M.T. help in diagnosis of Tuberculosis in almost 50% of the cases.

Child health, poverty and the environment: the Canadian context.

In Canada, there has been little research exploring the link between child poverty and exposure to environmental contaminants. However, children living in poverty are more likely to grow up in neighbourhoods adjacent to polluting industries and heavily used transportation corridors. They are also more likely to live in improperly designed or maintained buildings where levels of contaminants and toxic residuals may be high, and indoor air quality poor. Risk factors such as exposure to cigarette smoke and poor nutritional status, together with the above living conditions during growth and development, create conditions that make children living in poverty more vulnerable to the effects of environmental contaminants. In Toronto, the South Riverdale Community Health Centre is developing grassroots techniques to build awareness and protect citizens. Given the growing levels of child poverty in Canada and decreasing environmental protection, the author suggests increased community action and health research for use in advocating for appropriate policy changes.
