The hemolytic - uremic syndrome (HUS) presents with a triad of acute renal failure, microangiopathic hemolytic anemia and thrombocytopenia associated with high morbidity and mortality. On the differential diagnosis, other entities must be considered like preeclampsia, HELLP syndrome, acute fatty liver of pregnancy and thrombotic thrombocytopenic purpura. We report a case of HUS occurring in the immediate postpartum period in a patient initially diagnosed as having preeclampsia. The differential diagnosis was based on abrupt renal failure, blood pressure increase and clinical and laboratorial evidence of hemolysis. Attention is directed to investigation, clinical management and prognosis based on review of the literature.

Purpose: to evaluate if multiple courses of antenatal corticosteroids are more effective than single ones to reduce morbidity and mortality of preterm infants. Methods: retrospective study of 184 newborns with gestational age less than 34 weeks from a tertiary-level hospital in São Paulo from January 1988 to December 1998. The patients were divided into two groups: single course (n=135) - newborns whose mothers were exposed to a complete single course (2 doses of betamethasone or 4 doses of dexamethasone between 24 h and 7 days prior to delivery); multiple courses (n=49) - newborns whose mothers were exposed to two or more complete courses. The primary clinical outcomes for the two groups were: frequency of respiratory distress syndrome (RDS), intra-hospital mortality and combined neonatal morbidity (including the presence of the following: RDS, peri-intraventricular hemorrhage, bronchopulmonary dysplasia, necrotizing enterocolitis, sepsis or intra-hospital death). Numerical data were compared by Student's t test or Mann-Whitney test and categorical data by chi² or Fisher exact test, with the odds ratio and its confidence interval. Results: there were no differences between the groups that received single or multiple courses of antenatal corticosteroids in regard to the occurrence of RDS (single course: 22% and multiple course: 18%), intra-hospital mortality (single course 18% and multiple 12%) and combined neonatal morbidity (single course 62% and multiple 63%). Conclusions: multiple courses of antenatal corticosteroids did not reduce the morbidity and mortality of preterm infants. This study emphasizes the present guidelines that recommend the use of one single course of corticosteroid for fetal maturation in pregnant women at risk for preterm delivery.

Purpose: to study pregnancy in adolescent women as a possible risk factor for low birth weight. Material and Methods: a cross-wide study was performed on 562 adolescent and non-adolescent mothers who were interviewed during the first 24 h after delivery in the period from January 10,2002, to March 25, 2002, in a public maternity hospital located in Rio Branco, Acre State, Brazil. Those who delivered dead fetuses, whose babies died after being born, or had twins were excluded from the study. Results: among the 562 mothers who were studied, 37.0% (n=208) were teenagers (16±1.6 years), and 63.0% (n=354) were 20 or more years old (22.9±6.3 years). The average weight of the newborns was statistically higher (p<0.010) among the adult mothers (3,158.64±626.50 g) than among the adolescent mothers (3,019.93±587.43 g). When the 32 (5.7%) premature newborn babies (<37 week's pregnancy) were excluded, there was also a significantly greater proportion (p<0.007) of newborns with low weight (<2,500 g) among the adolescent mothers (11.9%) than among the non-adolescent ones (5.5%). The analysis of logistic regression showed an increased risk for newborns with low weight among the adolescent mothers (OR=2.99; 1.47-6.07), as well as for abortion (OR=2.78; 1.23-6.30) and pregnancy - induced hypertensive disorders (OR=5.16; 1.65-16.12). Conclusions: the present study shows that associated with the psychosocial, familial, and economic impact, already reported in the literature, pregnancy in adolescents is associated with deleterious effects on the conceptus, which requires a cohort study to assess the repercussions at both the medium- and long-term.

Purpose: to assess the evolution of epileptic seizures during pregnancy and the occurrence of malformations in neonates born to epileptic mothers who used anticonvulsant drugs during pregnancy, as well as the perinatal characteristics of the newborns. Methods: a total of 126 medical records of epileptic patients seen at the high-risk pregnancy outpatient clinic were analyzed retrospectively in terms of the following variables: age, parity, diagnosis of the type of epileptic seizure, anticonvulsant drug used during the prenatal period, evolution of epileptic seizures during the prenatal period, type of delivery, gestational age at resolution, and perinatal characteristics of the newborns. Results: the incidence of pregnant women with epilepsy was 0.2% in relation to prenatal patients, with simple partial epilepsy being the most frequent type (40% of cases). Monotherapy was applied to 75% of the patients and carbamazepine was the most frequently used drug. Among the 111 patients evaluated in terms of course of the disease during pregnancy, 53% showed no change, 31% became worse and 16% improved. Normal delivery was performed in 62.5% of cases, with a satisfactory perinatal result in terms of Apgar score, and with a rate of low birth weight neonates above the values for low-risk populations. No fetal malformations were observed. Conclusion: epilepsy showed a favorable course during pregnancy and was not aggravated by the latter, with cases of worsening of signs and symptoms being associated with epilepsy of difficult control before pregnancy. Evaluation of the perinatal characteristics of the neonates showed satisfactory Apgar scores and evolution, indicating that epilepsy and anticonvulsant drugs do not cause severe impairment of intrapartum vitality. No cases of malformations or hemorrhagic complications were detected in the present study.

Purpose: to analyze the perinatal results of patients submitted to a 100 g oral glucose tolerance test (OGTT) during prenatal care at the Instituto Materno-Infantil de Pernambuco (IMIP), according to three different criteria. Methods: a cross-sectional study was conducted involving 210 pregnant patients attended at the IMIP, who were tested by a 100 g OGTT and had a singleton, topic pregnancy, without history of diabetes or glucose intolerance before pregnancy, and who delivered at the IMIP. The patients were classified into one of the following categories according to the levels found by OGTT: controls, mild hyperglycemia, Bertini's group, Carpenter's group and the National Diabetes Data Group (NDDG). These classes were then compared and association between the categories and preeclampsia, large for gestational age (LGA) newborns, rate of cesarean delivery, stillbirth, and mean birth weight was investigated. Results: the frequency of gestational diabetes was 48.1, 18.1, and 9% according to Bertini's, Carpenter and Coustan's and NDDG criteria, respectively, and mild hyperglycemia was present in 10.5%. Age of patients increased with a higher degree of carbohydrate intolerance. The groups did not differ regarding frequency of LGA, C-section, stillbirths, and birth weight. There was an increased frequency of preeclampsia among women with hyperglycemia and gestational diabetes according to Carpenter and Coustan's criteria. Conclusions: prevalence of gestational diabetes varied between 9 and 48% according to the different criteria, but maternal and perinatal results did not differ significantly among the groups. Strict diagnostic criteria can determine overdiagnosis without improvement of perinatal outcome.

Purpose: to study the association between long-standing type 1 diabetes with bad glycemic control and breast inflammatory lesions which can simulate inflammatory carcinoma. Patients and Methods: eighteen patients were studied, retrospectively, in a mastology reference center from January 1998 to December 2001, presenting with breast inflammatory lesion with or without palpable mass. They were submitted to serum glucose and glycosylated hemoglobin determination, as well as image examination and histopathologic analysis, and diabetic mastopathy was diagnosed. Results: the patients' average age was 50.2 years, and all had insulin-dependent diabetes mellitus, with average disease time of 14.9 years. All patients, with no exception, had a bad glycemic control; the average blood glucose was 329.6 mg/dL and the glycosilated hemoglobin average was 9.7%. NPH insulin dose being applied per day was 37.2 units. Patients underwent a clinical treatment with antibiotics and control of the glycemic levels with NPH insulin and had resolution of the symptoms in about five weeks. Conclusion: the professionals involved in women health care must be aware of this inflammatory pathology of the breast and its benign characteristics to avoid unnecessary procedures sometimes with patient injury.

Purpose: to evaluate the diagnostic accuracy of sonohysterography as a diagnostic method for the evaluation of the uterine cavity in postmenopausal women with abnormal uterine cavity at conventional endovaginal sonography. Methods: this study consisted of the evaluation of 99 postmenopausal patients with abnormal uterine cavity on conventional endovaginal sonography, that was defined as endometrial thickness equal to or larger than 5 mm in a postmenopausal patient not on hormone replacement therapy, or endometrial thickness equal to or larger than 8 mm in patients on hormone replacement therapy, with irregular bleeding. These patients were subjected to sonohysterography, and specimens were obtained for pathologic examination by biopsy guided by histeroscopy in 92 patients, endometrial biopsy in four patientes and hysterectomy in three patients. The results of sonohysterography were compared with the pathologic findings, considered "gold standard". Results: there were eight cases of normal uterine cavity and 20 cases of atrophic endometrium and sonohysterography had high levels of specificity (97.8 and 97.5%) and low sensitivity (35 and 25%). There were high levels of sensitivity (92.3 and 75.0%) and specificity (94.1 and 97.9%) for polyps (65 cases) and submucous myomas (four cases). There were three cases of endometrial carcinoma and the sonohysterography had a sensitivity and specificity of 100%. Conclusions: sonohysterography showed to be accurate in the diagnostic of focal diseases (endometrial polyps and submucous myomas). There were three cases of endometrial cancer, and sonohysterography correctly diagnosed all of them. This method was also accurate to exclude endometrial abnormality. However, in the cases of diffusely thickened endometrium, the accuracy was low, because atrophic and normal endometrium on histopathology frequently appears as diffusely thickened endometrium at endovaginal sonography and sonohysterography. Sonohysterography did not lead to complications during and after the procedure.
