PURPOSE: to study the causes and associated factors of fetal death. METHODS: epidemiological descriptive study, composed of 190 cases of fetal loss amongst 11,825 pregnant women that gave birth at the two only hospitals (Casa de Saúde Divino Espírito Santo and Hospital Nossa Senhora Auxiliadora) of Caratinga City, in the State of Minas Gerais, Brazil, in the period from January 1, 1995 to April 30, 2000. The variables were the number of pregnancies, the timing of the pregnant women at the time of hospitalization, the occurrence of fetal death in relation to delivery and the cause of fetal death. Since there were no comparative groups, tables, percentages and arithmetical means were applied, following the guidelines of the Course of Statistics, of the "Universidade Federal de São Paulo". RESULTS: among the 189 pregnant women with fetal death, 77 were primigravidal and 76 had already been pregnant 2 to 5 times. The gestational age in 113 women was from 20 to 37 weeks. In relation to parturition, the fetal loss occurred during the antepartum period in 164 of 190 dead fetuses. The most frequently noticed death causes were: abruptio placentae in 35 cases, fetal anomaly in 12 cases, and hypertension syndrome in 8 cases. Nervertheless, there was no explanation for the etiology of 117 cases of fetal death. CONCLUSION: stillbirth has frequently been observed among the primigravidae (40.74%), in preterm period (59.79%), and in the antepartum period (86.31%). Among fetal death causes, the most frequent was a abruptio placentae (18.42%), and in 61.57% of the cases the fetal death could not be explained.

PURPOSE: to evaluate maternal and perinatal outcomes of premature rupture of membranes up to the 26th week of gestation. METHODS: retrospective analysis of the cases of premature rupture of membranes up to the 26th week of gestation, without signs of labor or treatment for this condition before admission, followed up at the Obstetric Pathology Infirmary of the "Maternidade Escola Assis Chateaubriand", Federal University of Ceará, from January 1994 to December 1999. The cases with gestational age less than 22 weeks and birth weight lower than 500 g were excluded. Premature rupture of membranes was confirmed by sterile speculum examination. In doubt, amniotic fluid crystallization test and pH determination were performed. All pregnant women underwent ultrasound examination to determine gestational age and amniotic fluid volume. Data concerning the result of gestation and consequences for the mother, fetus and neonate were analyzed. RESULTS: a total of 29 cases of premature rupture of membranes fulfilled inclusion criteria. The mean gestational age at rupture of membranes was 22 weeks. The mean duration of the latency period was 21.7 days. There Were 22 spontaneous vaginal and 3 induced deliveries, besides 4 cesarean sections. In six pregnant women there were signs of infection before labor. Antibiotics were administered in 37.9% of the cases and corticosteroids in 6.9%. No patient underwent tocolysis. There were 3 fetal and 25 neonatal deaths. Only one infant survived. This child remained at the neonatal care unit for 19 days due to infection and respiratory distress syndrome. There was no maternal death. CONCLUSION: the premature rupture of membranes up to the 26th week of gestation has been a fatal discase for fetuses and newborns in our institution.

PURPOSE: to establish a normality curve of cervical length during pregnancy measured by transvaginal ultrasonography. METHODS: we conducted a prospective, longitudinal study on 82 healthy pregnant women who were followed up from the beginning of pregnancy to delivery at four-week intervals, of whom 49 concluded the study. Patients were divided according to parity into nulliparous women and women with one or more previous deliveries. Cervical length was measured in a sagittal view by transvaginal ultrasonography, as the linear distance between internal and external cervical os. RESULTS: no significant difference was observed in mean cervical length or the 5th, 25, 50th, 75th, or 95th percentile according to gestational age between groups (p>0.05). Between the 20thand 24th gestacional week, the 5th, 50th and 95th percentiles of cervical length were 28, 35 and 47.2 mm, respectively. Cervical length decreased progressively during normal pregnancy, with a significant shortening observed after 20 weeks of gestation and being more marked after 28 weeks (p<0.05). CONCLUSION: the pattern of cervical length behavior does not seem to differ between nulliparous women and women with one or more previous deliveries. The numerical values of the normality curve of cervical length according to gestational age reflect the variability in the peculiar characteristics of the studied sample, thus emphasizing the value of the parameters established for different populations.

PURPOSE: to analyze obstetrical and perinatal data in 26 cases of meconium aspiration syndrome (MAS). METHODS: a retrospective review was performed in 26 newborn records diagnosed with meconium aspiration syndrome. Patients were studied emphasizing average days in neonatal intensive care unit and main maternal findings and neonatal complications, correlating them with each other. RESULTS: Eighteen babies were delivered at GH-CSUF and eight out of this hospital. At this time 3,976 deliveries occurred at GH-CSUF, with an incidence of MAS of 0.45%. Nine of 18 babies were born by vaginal delivery; weight was >2,500 g in 16 cases. One-minute Apgar score was >7 in three cases (16.7%), between 4 and 6 in seven cases (38.9%), and between 0 and 3, in eight cases (44.4%). At 5 minutes, seven babies remained <7. Anoxia was the main neonatal complication (36%). The mortality rate was 7.7% and the average hospital stay was 19.9 days. CONCLUSION: MAS is a very important neonatal pathology correlated with high neonatal mortality rates, thick meconium in at least half of the cases, and with a majority of depressed newborns at delivery.

Liposarcoma is a rare neoplasia that originates from primitive mesenchymal cells and is the most common histological type of sarcoma. It mainly affects the limbs but can reach other regions. Genital localization is, however, rare. The authors report a case of vulvar liposarcoma in a 27-year-old patient, who presented a progressively growing mass that limited her movements. Physical examination showed a large ulcerated vulvar tumor. The patient underwent local resection and histopathological examination diagnosed a well-differentiated liposarcoma with uncompromised margins. At the present time, 24 months after surgery, the patient is well and without recurrence of the disease.
