A case of squamous cell carcinoma arising in a dermoid cyst of the ovary of a 38 year-old woman is reported. Its frequency is nearly 1%; nevertheless it is opinion that the real frequency could be higher if the hystological examination of the cyst would be made more accurately. Clinical and pathological findings of this case are presented in this brief note. The importance to always make an intraoperatively frozen-section examination is emphasized. The patient is alive and well after six months after surgery.
The data collected from women who delivered in the Institute of Obstetrics and Gynecology of the University of Parma since 1/7/81 till 31/12/81 were compared to those of the Obstetric-Pediatric Policentric Study of the Subproject of Perinatal Medicine sponsored by N.R.C. (National Research Council) collected since 1973 to 1977. The maternal wish of pregnancy and the total number of obstetrical controls during pregnancy were higher in the data of Parma than in the data of N.R.C. No differences between the two groups were noted in the obstetrical pathological patterns. Spontaneous labor and elective cesarean section are more frequent in Parma meanwhile there is a minor incidence of low weight newborn and perinatal mortality. No difference was noted in the preterm labor incidence.

The oral glucose tolerance test has been traditionally used to detect women with the gestational form of impaired glucose tolerance. We investigated whether the assessment of HbA1 levels could be a useful adjunct to these measurements. We found that HbA1 levels measured after the 35th week are not predictive of the percentile of each neonatal anthropometric parameter. Both metabolic and clinical maternal parameters as well as neonatal anthropometric parameters must also be evaluated.
In the present study the Authors considered some neonatal anthropometric parameters such as head and chest circumference besides the neonatal weight and placental weight that may be more expressive of the fetal growth. All these parameters were correlated separately and jointly with maternal HbA1 levels of the third day of the post partum period. All mothers spent a pregnancy without any clinical and metabolic disorder. The data show a significant higher HbA1 mean value, than the controls, in mothers whose newborn showed one or more parameters like/superior the 90th centile. This finding may suggest that the evaluation of all the parameters together, the maternal HbA1 value can give more informations about the fetal growth.
A prospective randomized clinical trial was conducted to test the effectiveness of long-term and short-term prophylaxis with cefuroxime in preventing morbidity after cesarean section. Sixty patients who required emergency cesarean section were randomly assigned to one of three treatment groups: a control group of 20 patients receiving no prophylactic antibiotics; a group of 20 patients receiving 24 hours of cefuroxime prophylaxis (0.75 gm 30 to 60 minutes before surgery and at 8 hours and 16 hours after surgery); and a group of 20 patients receiving five days of cefuroxime prophylaxis (0.75 gm three times a day, the first dose being given postoperatively). The short-term and long-term prophylaxes were equally effective in reducing morbidity, assessed by postoperative temperatures, presence or absence of endometritis, and duration of postoperative hospital stay.

Postpartum HbA1 levels were studied in 114 mothers with a normal pregnancy. HbA1 levels were correlated with neonatal anthropometric parameters and with maternal metabolic parameters. A strong positive correlation was found between weight gain during pregnancy and postpartum HbA1 levels. There was also an increased frequency of infants with large thoracic circumference born to mothers with HbA1 levels above 8.6%. Thus, postpartum HbA1 levels in mothers in whom the serial HbA1 determination is not possible, may be a useful index of glucose control during the gestational period.
