Idiopathic thrombocytopenic purpura in pregnancy: a single institutional experience with maternal and neonatal outcomes.

We observed 13 pregnant women of 70 females with idiopathic thrombocytopenic purpura (ITP) from January 1992 through September 2002. Thirteen mothers with ITP gave birth to twelve babies and two fetuses died. One of the pregnancies produced twins. Seven of the cases were diagnosed with ITP before pregnancy and six during pregnancy. One of the thirteen pregnancies was complicated by preeclampsia, one by ablatio placentae, and one by intrauterine death. Seven mothers received corticosteroid treatment, four high-dose immunoglobulin therapies, and one underwent splenectomy in the second trimester of gestation. At the time of delivery six mothers had normal platelet counts and seven had low platelet counts. Nine deliveries were by vaginal route and four were by cesarean section. Eleven infants were born with normal platelet counts and one was thrombocytopenic at the time of delivery. No infant showed any clinical signs of hemorrhage and there were no neonatal complications. Two fetuses died; one of them because of ablatio placentae and the other was intrauterine dead. In conclusion, ITP in pregnancy requires the management of two patients, the mother and her baby; hence, the close collaboration of a multidisciplinary group composed of a hematologist, obstetrician, anesthesiologist, and neonatologist is essential.

Placental and decidual lipid peroxidation and antioxidant defenses in preeclampsia. Lipid peroxidation in preeclampsia.

We evaluated lipid peroxidation in serum, placenta and decidua basalis and antioxidant defenses in preeclampsia and normal pregnancy. The study group consisted of 70 women with preeclampsia and 72 healthy pregnant women. Lipid peroxides in serum, placenta and decidua basalis, and serum vitamin E and total carotene were measured by spectrophotometric methods. Unpaired Student's t-test, chi(2)-test and Pearson correlation test were used for the statistical analyses. Levels of lipid peroxides in serum, placenta and decidua basalis were markedly higher; and serum vitamin E, total carotene, bilirubin, albumin levels were markedly lower in preeclamptic pregnants compared with healthy pregnant women. Our findings demonstrated that both placenta and decidua basalis tissues may be a source of lipid peroxides in preeclamptic pregnancies. Prophylactic antioxidant therapy may abate the disease process. Further studies are needed to clarify the pathophysiology of preeclampsia and effectiveness of prophylactic antioxidant therapy in preeclampsia.

The role of plasma renin activity in distinguishing patients with polycystic ovary syndrome (PCOS) from oligomenorrheic patients without PCOS.

All the components of the renin-angiotensin system have been identified in the human ovary. Renin plays a major role in folliculogenesis, and possibly in follicular atresia. Polycystic ovary syndrome (PCOS) is characterized by early follicular atresia. We studied whether assessment of plasma renin activity would be useful for diagnosing PCOS and distinguishing PCOS and non-PCOS in oligomenorrheic patients. Patients were divided into three groups: PCOS group (group 1, n = 40), non-PCOS oligomenorrheic group (group 2, n = 30) and ovulatory control group (group 3, n = 30). Plasma renin activity was determined in the early follicular phase of the menstrual cycle. Baseline serum levels of follicle stimulating hormone (FSH), luteinizing hormone (LH), prolactin, insulin, aldosterone and androgens (total testosterone, free testosterone, androstenedione, dehydroepiandrosterone sulfate and 17alpha hydroxyprogesterone) were determined in all groups. The mean LH level was lower (4.94 +/- 4.65 mIU/ml) in control patients than in PCOS patients (12.9 +/- 1.75 mIU/ml) and non-PCOS oligomenorrheic patients (10.8 +/- 1.65 mIU/ml). There was no statistically significant difference between the groups regarding FSH levels. The mean plasma renin activity was 3.47 +/- 0.29 ng/ml in the PCOS group. The mean plasma renin activity was 1.59 +/- 0.21 ng/ml the non-PCOS oligomenorrheic group (statistically significiant differrence). There was no statistically significant difference between the non-PCOS oligomenorrheic (1.59 +/- 0.21 ng/ml) and control groups (1.2 +/- 0.16 ng/ml). Use of plasma renin activity alone as a diagnostic marker in PCOS is not useful, because the clinical findings of PCOS are heterogeneous and the pathogenesis is unclear. However, it can be used together with other variables to diagnose women with PCOS and to distinguish non-PCOS oligomenorrheic women from those with PCOS.

Activated protein C levels in patients with gynecologic tumors.

Activated protein C (APC) levels were measured in the plasma of patients with benign and malignant gynecologic tumors preoperatively, and on postoperative days 1 and 7. Preoperative levels of APC were found to be significantly low in both groups of patients compared to a group of healthy subjects. On postoperative day 1, levels of APC decreased significantly in both groups of patients compared to preoperative levels. By the 7th postoperative day, levels of APC in patients with benign tumors had increased significantly compared to postoperative day 1; levels in patients with malignant tumors, however, remained low. Our findings imply that there is a substantive correlation between gynecologic tumors, gynecologic surgery and the coagulation inhibitor, APC, which, in turn, can presumably be used to identify gynecologic patients who are at high risk for venous thrombosis.

Pelvic-peritoneal tuberculosis with elevated serum and peritoneal fluid Ca-125 levels. A report of two cases.

We report 2 patients with pelvic-peritoneal tuberculosis and elevated serum and peritoneal fluid levels of Ca-125. The first was a young and infertile women who had cul-de-sac nodularity and dysmenorrhea. The other was postmenopausal and presented with weight loss and ascites. While a preoperative diagnosis of endometriosis was made in the former, intraperitoneal malignancy was considered in the latter. The diagnosis of pelvic-peritoneal tuberculosis was reached by laparoscopic-directed biopsy in both patients. Serum levels of Ca-125 returned to normal limits following antituberculous drug treatment.

Complications of radical vulvectomy and inguinal lymphadenectomy for the treatment of carcinoma of the vulva.

Forty-two patients with invasive carcinoma of the vulva, subjected to radical vulvectomy and inguinal lymphadenectomy, were evaluated retrospectively. The mean age of patients was 61.6 years. Fifteen patients (35.7%) had complicating medical diseases, the histopathological diagnoses were squamous carcinoma (n = 39), undifferentiated carcinoma (n = 1), and malignant melanoma (n = 2). The postoperative morbidity and mortality rates were found to be 73.8% and 11.6%, respectively.

Prognosticators of second-look laparotomy findings in patients with epithelial ovarian cancer.

Prognosticators of outcome at second-look laparotomy (SLL) were evaluated in 49 patients with epithelial ovarian carcinoma undergoing SLL. Residual tumor volume was found to be the most significant prognosticator of outcome, with initial tumor stage being of secondary importance. Grade of tumor played no role in outcome at SLL. The results of the study led us to the conclusion that the second-look procedure may be safely omitted in stage I patients. The importance of optimal cytoreduction during primary surgery was stressed.

The value of human menopausal gonadotropin treatment in patients with unexplained infertility.

The role of multiple ovulation with human menopausal gonadotropin (HMG) in the treatment of unexplained infertility is evaluated. Of a total 73 patients with unexplained infertility, 39 received four cycles of HMG, whereas, 34 were left untreated. Eight (20.5%) women conceived during HMG treatment, in comparison to only 1 (2.9%) in the control group (P less than 0.05). This study gives further credit to the value of HMG treatment for unexplained infertility.

Evaluation of adhesion formation after laparoscopic treatment of polycystic ovarian disease.

The incidence and fertility effects of postoperative adhesion formation after laparoscopic ovarian electrocautery or laser photocoagulation of polycystic ovaries has not been adequately analyzed. Short-interval second-look laparoscopy appears to be a useful method for addressing this issue. Employing short-interval second-look laparoscopy 3 to 4 weeks after the initial laparoscopic intervention, we were able to demonstrate adhesions in 6 of 7 patients (85%) treated with ovarian electrocautery and 8 of 10 patients (80%) submitted to laser therapy. The adhesions were amenable to laparoscopic lysis in 12 of 14 patients (85%). The subsequent conception rates within 6 months of second-look laparoscopy that were 57% and 40% in the electrocautery and the Nd:YAG laser groups, respectively, may in part be attributed to the restoration of normal pelvic anatomy during this procedure.

Digoxin-like immunoreactive substance and preterm labor.

An endogenous digoxin-like substance (DLIS) that may be related to preterm labor has been studied. Using a commercially available radioimmunoassay kit. DLIS levels were determined in 110 women, of whom 33 were in preterm labor, 27 were in labor at term, 26 had normally ongoing pregnancies before term and were not in labor, and finally 24 were at term but not in labor. Mean DLIS levels of women in preterm labor was found to be significantly high (greater than 0.2 ng/ml, p less than 0.05). Whether this finding points to a causative role for DLIS in preterm labor remains to be further investigated.

Serum and peritoneal fluid CA-125 levels in early stage endometriosis.

Serum and peritoneal fluid (PF) CA-125 levels were assayed using the immunoradiometric assay in 17 women with minimal endometriosis and 21 control women at the time of laparoscopy. Serum levels of CA-125 were not significantly higher in women with minimal endometriosis. Minimal endometriosis was diagnosed with a 70.6% rate of sensitivity and a 71.4% rate of specificity with 16 U/ml as the upper limit of normal. PF CA-125 levels were significantly higher than serum levels but showed no significant difference between control and endometriosis patients.
