We report a case of early abdominal pregnancy (6 weeks amenorrhea). The diagnosis of ectopic pregnancy was suspected according to the usual clinical, serologic, and sonographic procedure. It was confirmed by laparoscopy. Laparoscopic surgery was unable to assess the trophoblastic site and the hemostasis of the lesion that was histologically proven.
We report one case of pregnancy in a non-oriental woman who had Takayashu's disease. Pregnancy was characterised by toxemia and caesarean section had to be carried out at 31 weeks because of fetal distress. The disease did not worsen and nor were there any maternal complications but the child died on the 7th day.

A retrospective study was done to appraise the recent practice of breech extraction of the second twin (with or without internal version) in our unity. From January 1st, 1988 to April 30, 1991 23 patients with a twin gestation were delivered in our unity (0.5% of all deliveries). Nineteen patients (83%) were delivered vaginally. Each procedure was done by a resident under control of a senior obstetrician and in the presence of two midwives, a pediatrician, and an anesthesiologist. Ten patients having had a breech extraction (GE group) were studied, 13 patients were excluded for not having had a breech extraction. In the GE group the presentations were: 7 vertex/breech and 3 breech/breech. Mean Apgar scores of the second twin at 3 minutes were 8 in the GE group. These results suggest that breech extraction of the second twin is not a pernicious technique if done by trained operators with precise limits. These results need to be confirmed through a prospective randomized and comparative study.
An exploratory examination of the possibility of using multiple causes of death information from death certificates in mortality studies has been undertaken. The formation of a matrix of primary by contributory causes has been suggested. The matrix gives an overall picture of mortality patterns, serves as a scheme to identify disease combinations, and can be utilized as a data-editing device. From the matrix, several conventional, as well as several new statistics can be computed. The methodology has been illustrated with data from a cohort of steelworkers. The gain in information as a result of routinely recording multiple causes of death has also been discussed.
