Current status of sterilization.

About 50 per cent of child bearing women in Australia are being sterilized. The selection of patients for the procedure requires careful counseling in order to avoid the risk of regret. Factors increasing the risk of regret are enumerated. Laparoscopy is the most popular method for sterilization, but mini laparotomy is a reasonable alternative for patients not having access to skilled laparoscopists. Clips and rings provide a greater chance of successful reversal of sterilization, and are recommended for use in younger women. The sequelae of sterilization are slight, with failure of technique, infection and temporary regret being the commonest. Serious psychological or physical sequelae are rare. If reversal is required the microsurgical technique is recommended.

Disseminate and recurrent infundibulofolliculitis.

Disseminate and recurrent infundibulofolliculitis is an uncommon pruitic papular follicular eruption that affects the trunk and proximal extremities and occurs almost exclusively in blacks. Little is known about the cause, and treatment has been totally unsuccessful. Extensive laboratory investigations, including histology and direct immunofluorescence in four cases, were unrevealing. Oral vitamin A therapy was effective in controlling five of six cases. We consider this disease to be a specific clinical and pathologic response to an, as yet, unknown cause or causes.

Perinatal asphyxia and outcome of very low birthweight infants.

Seventy-eight very low birthweight (VLBW) infants (whose birthweights were 1500 g or less) were admitted to the Neonatal Special Care Unit in 1977. Seventy-two of them required treatment in the intensive care area; these represented 40% of admissions to that area of the Unit. The mortality rate was 20% for infants weighing 1001 g to 1500 g, and 52% for those weighing 501 g to 1000 g. An Apgar score of 0 to 3 at two minutes and five minutes was reported in 34% and 19% of VLBW infants respectively. Although there was no difference in birthweight between the groups with a high or low Apgar score, the mortality rate of infants with a five-minute Apgar score of 0 to 3 was 79% compared to 22% in those with a score of 4 to 10. Over 50% of the infants developed hyaline membrane disease regardless of Apgar score. However, in the infants with a five-minute Apgar score of 0 to 3, the severity of respiratory insufficiency was increased as indicated by increased requirement for high inspired oxygen, and the need for intermittent positive pressure ventilation. The duration of stay in the neonatal intensive care area, and the total length of hospital stay of the 49 VLBW survivors were shorter in the group with higher two-minute and five-minute Apgar scores. Long-term morbidity cannot yet be ascertained. It is likely that prevention, or prompt detection, and appropriate management of perinatal asphyxia would produce a further decline in mortality as well as morbidity for VLBW infants.

Continuous measurement of tissue pH in the human fetal scalp.

A method for continuous measurement of scalp tissue pH is described. The tissue pH probe was found to be robust and values for tissue pH were close to those for scalp blood pH. Combining the pH and fetal heart fate (FHR) electrodes in the one mechanical assembly facilitated application to the fetal scalp in early labour but the combined assembly electrode was found to have some disadvantages and manufacture of a separate tissue PH electrode is recommended. Continuous monitoring of scalp tissue pH enables closer study of the physiological basis of changes in fetal acid base status and should prove useful to the obstetrician in management of high risk pregnancies during labour.

Menopausal hot flushes: a double blind comparison of placebo, ethinyl oestradiol and norgestrel.

A double blind crossover study was planned in order to compare the effects of oestrogen, progestogen and placebo on hot flushes. The 49 women studied had previously undergone hysterectomy and bilateral oophorectomy. The drug regimen consisted of three months each of ethinyl oestradiol 50 microgram/day, d norgestrel 250 microgram/day, a combination of these two substance ("Nordiol") and a placebo. The predominant reason for requesting a change of medication was intolerable hot flushes associated with placebo use. All hormonal preparations were found to be significantly more effective than placebo in reducing hot flush frequency and intensity. Oestrogen containing medications were more effective than the progestogen (norgestrel).

New aspects of the treatment of tubal infertility.

Three aspects of the treatment of tubal infertility are discussed: current surgical procedures, including the use of microsurgery; an attempt at tubal transplantation; and the use of in vitro fertilization.

Clinical features and plasma hormone levels after surgical menopause.

This study reports the plasma levels of follicle stimulating hormone, luteinising hormone, oestradiol and testosterone in 43 women who had undergone bilateral oöphorectomy. Age was the only variable of those investigated which appeared to influence a hormone level; testosterone levels were found to decrease with increasing age. Two significant associations were found between clinical features of the menopause and the plasma hormone levels measured. Low levels of oestradiol were associated with pruritus vulvae and high levels of testerone were associated with headaches.
