Mortality rate of Japanese twins and triplets. II. Socioeconomic factors influencing infant deaths of twins after birth to one year of age.

The rates of infant mortality of twin individuals were 4.38% and 7.76% for mothers healthy and nonhealthy after delivery, respectively, and the difference is significant at the 0.01 level. The lowest infant mortality rate was seen in the mothers with paid work during pregnancy (4.56%), followed by the mothers engaged only in housekeeping (4.72%) and by those self-employed during the pregnancy (4.99%). Infant mortality rate for MZ twins decreased with increased monthly expenditure of the household, whereas the rate for DZ twins remained constant with expenditure. Socioeconomic factors still affect the infant mortality of twins, and the infant mortality rate can be improved.

Mortality rate of Japanese twins and triplets. III. Infant deaths of triplets after birth to one year of age.

The rate of infant mortality of triplet individuals (deaths under one year of age) was computed using 34 sets of triplets born in the first half of 1974. The rates were 8.82%, 9.68%, and 10.34% for the first-, second-, and the third-born triplets, respectively. For males and females the rates were 8.33% and 10.34%, respectively, and the difference was not significant. The rate decreased with gestational age up to 32-35 weeks. For those with heavier weight at birth (less than or equal to 2,000 g) the rate was lower (0%) than for those with lighter weight (less than 2,000 g, 8.16%), but the difference is not significant (P = 0.087). Infant mortality rate of triplets decreased with increased monthly expenditure of the household.

Study of HLA antigens among Japanese schizophrenics.

HLA antigens were typed among 136 Japanese schizophrenics. Increased frequencies were seen in A9 (Aw24), A10 (A26) and Bw54, and decreased frequency in B40 antigens when compared to 187 Japanese controls. It is suggested that there may be an association between A9 (Aw24) and schizophrenia with a chronic-progressive course and also an association between A10 (A26) and hebephrenia.

Studies on pituitary-gonadal endocrine function in XYY men.

Serum luteinizing and follicle-stimulating hormones and testosterone levels were studied in 11 patients with 47-XYY chromosomes and a comparison was made to normal men and patients with other testicular diseases, including Klinefelter's syndrome. Serum follicle-stimulating hormone levels in patients with XYY chromosomes were elevated significantly in comparison to those in normal men but lower than those in men with Sertoli cell only syndrome and Klinefelter's syndromes. Serum luteinizing hormone levels were somewhat elevated and serum testosterone levels were somewhat low in comparison to normal men, although the difference was not significant. Results of the short-term human chorionic gonadotropin stimulation test suggested almost normal Leydig cell reserve capacity in patients with XYY chromosomes.
