Carcinoma of the vulva arising in condylomata acuminata.

A case of carcinoma of the vulva arising in condylomata acuminata is presented. The patient was much younger than is classically reported for carcinoma of the vulva. The vulvar growth was first noted during pregnancy, and it continued to grow and enlarge following delivery. Malignancy appeared to develop after a relatively short time. It is sometimes difficult to distinguish vulvar condylomata acuminata from carcinoma from clinical evidence alone. It is, therefore, mandatory in doubtful cases to take multiple biopsies from the lesion before treatment is instituted.

The hysterographic diagnosis of stromal endometriosis.

The hysterographic appearances in three histologically verified cases of stromal endometrosis are presented. Interpretation of the unusual radiographic findings on the basis of uterine pathology is attempted. Little is known about the preoperative diagnosis of the disease. A triad of uterine enlargement, endometrial stromal hyperplasia with few or no glands in the curettings and unusual hysterographic findings strongly suggests a diagnosis of stromal endometriosis.

Effects of contraceptive pills and intrauterine devices on urinary bladder.

The incidence of bacteriuria and cystoscopic changes in women on oral contraceptives or users of IUD (intrauterine devices) were evaluated compared with a control group. Subjects with bacteriuria accounted for 40.5 per cent of pill users, 20 per cent of women fitted with IUD, and 16 per cent of the control group. Bladder trabeculations were found in 50.5 per cent of the pill group, 8.7 per cent of the IUD group, and 8 per cent of the controls. Congested bladder trigone was observed in 24.6 per cent of women fitted with an IUD. The mode of action of ovarian hormones and their possible side effects on the bladder are discussed. The relation of IUD to pelvic inflammatory disease and its effect on the urinary bladder are evaluated.

A note on the human sex ratio and factors influencing family size in Japan.

A reanalysis of a set of data on the sex distribution of children in Japanese families shows that further increase in family-size is related to the sex of the second child (P less than 0.025). When the second child is male, there is a reduced likelihood of further children. This result is consistent with findings from a U.S. fertility study.

A model for evaluating the effect of son or daughter preference on population size.

This paper develops a micro probabilistic model to describe the family extension process. The parameters are: the probability that a newborn is a boy (P), the number of desired boys (B), the number of desired girls (G), and the maximum possible number of children (N). This maximum is a stopping rule rather than a biological maximum. The variables are the ultimate number of boys and girls. According to this model, each couple determines B, G, and N, at the beginning of the reproductive period and continues to reproduce until at least B and at least G are achieved, or until the total number of children reaches N. The probability distribution of the ultimate number of boys and girls in the population is derived for this model. Simulation techniques are used to generate offspring. The results showed that the population size increases with the absolute differences, [B-G] for fixed N. They also suggested that son or daughter preference may be an important factor in fertility determinants, which may have important implications in population policies.
