RESUMO

OBJECTIVE: From data in the literature, we hypothesized that high vascular resistance values in the uterine arteries at the end of the first trimester would increase adverse pregnancy outcomes and therefore might be accompanied by changes in VEGF/VEGFR1 immunoreactivities. STUDY DESIGN: In our university hospital 82 women (Study I n=62 and Study II n=20) were divided into two groups according to their uterine vascular resistance values. Uterine vascular resistance values were measured in the 10-13th weeks of gestation by color-Doppler ultrasonography. Women were divided into low and high vascular resistance groups. In the prospective follow-up study (Study I) the data of the pregnancy outcome were recorded. In cross-sectional study (Study II), VEGF and VEGFR1 immunoreactivities were measured on the tissue samples from women who underwent termination of pregnancy. RESULTS: In the high vascular resistance group (PI>2.3), the probability of adverse pregnancy outcome was significantly higher (40.0% vs. 12.8%). No differences in VEGF and VEGFR1 immunoreactivities were observed between groups. In both groups, intense VEGF immunoreactivity was observed in the maternal glandular epithelium and in the decidual cells. Weak reactivity was observed in the villous trophoblast. VEGFR1 immunoreactivity was intense in all regions. CONCLUSIONS: Our data suggest that high vascular resistance values in the first trimester are independent from VEGF/VEGFR1 immunoreactivities and markedly increase the probability of adverse pregnancy outcomes. This may be used for early screening of pregnant women in the first trimester.

RESUMO

The influence of membranous glomerulonephritis (MGN) on maternal and fetal outcome is controversial, as is the effect of pregnancy on the course of preexisting nephrotic syndrome. We report a case of successful management of a pregnancy with preexisting severe nephrotic syndrome due to biopsy-proven primary MGN. Our patient became pregnant in a non-compliance period, discontinued the nephrological follow-up program and her kidney disease decompensated. From the 22nd gestational week the patient was treated with intermittent pulses of methylprednisolone (250 mg i.v.) and a maintenance dose of 32-64 mg/day orally, along with azathioprine 100 mg/day. She also received antihypertensive, diuretic, and anticoagulant therapy, and supplementation with fresh frozen plasma and albumin. In the 33rd gestational week a cesarean section was performed due to deteriorating creatinine clearance, low serum total protein levels, increasing edema and progression of intrauterine growth retardation of the fetus. Three months after delivery, the patient's renal disease went into complete remission. To our knowledge, this is the first report of using azathioprine during pregnancy with severe nephrotic syndrome due to primary MGN.

RESUMO

Pure rhabdomyosarcomas occurring in the adult uterus are very rare, with poor prognosis. We present a case of a 67-year-old woman with postmenopausal vaginal bleeding caused by pleomorphic rhabdomyosarcoma of the uterus, treated with hysterectomy, bilateral salpingo-oophorectomy, pelvic/paraaortic lymphadenectomy and partial sigmoidectomy. Postoperative chemotherapy (Doxorubicin) was given according to protocol. Follow-up examinations one year after surgery revealed no abnormalities or tumor recurrence. The rarity of this histological entity makes the presented case worthy of publication.

RESUMO

Congenital primary intracranial hemangiopericytomas are exceptionally rare tumors. We present a case of a fetus, with the prenatal sonogram at 33 weeks of gestation revealing a large cerebral tumor. Because of the enlarged head, a cesarean section was performed. The tumor was confirmed by postnatal ultrasound, magnetic resonance imaging (MRI) and biopsy. Elevated intracranial pressure and hemorrhage led to death on the 11th day. Autopsy revealed a 10x9 cm large inhomogeneous tumor located centrally, mainly in the posterior fossa. Histology showed a hypercellular and hypervascular tumor with extended necrosis and high mitotic rate. The tumor cells were positive for vimentin and CD34 antigens and negative for several neurological markers, desmin and CD31. The diagnosis of a congenital primary cerebral hemangiopericytoma was confirmed.

RESUMO

Cell-cell and cell-extracellular matrix interaction is crucial in tumor progression. Tight junction (TJ) proteins as occludin and claudins (CLDNs) play important role in this process together with several extracellular matrix components, as syndecan. Our previous work suggested significant changes in the expression of claudins even in the early stages of cervical carcinogenesis. The aim of our present work was to study the expression of occludin and syndecan-1, as compared to CLDNs, in early phases of cervical carcinogenesis. Paraffin sections of 50 samples were studied by immunohistochemistry, including cervical intraepithelial neoplasias (CINI-II-III), in situ carcinomas (CIS) and normal cervical samples. Occludin and CLDN-2 were found colocalized in the basal layer, while syndecan-1 and CLDN-1, -4 and -7 were coexpressed in the parabasal and intermedier layers in normal epithelia. Intensity of occludin staining decreased in CIN/CIS lesions, although it was more extended towards the upper epithelial layers with inverse relation with grades, as seen in the case of CLDN-2 expression. CLDN-1, -2, -4 and -7 were detected in the entire epithelium in CIN, showing decrease in CIS. The progression of CIN was associated with reduced syndecan-1 expression, in contrast to CLDN-1, -4 and -7 which increased toward CIS. The obtained data suggest that significant changes occur in the composition of cell adhesion complexes even in early stages of cervical carcinogenesis. The pattern of expression is characteristic for the alteration, the changes in the different components, however, are not parallel with each other.

RESUMO

Authors review a case of a 53 years old female patient with a cystic alteration 9 cm in diameter, located in the presacral region, in the medial line. Histological examination proved the mass to be a quite rare hindgut cyst which during surgery, however, did not show any connection with the rectum. The case is reported due to its relative rareness and the differential diagnostic questions emerging.

RESUMO

The authors present a case of a Sertoli-cell type androblastoma of the ovary. The tumor is mainly seen in young women and is mostly discovered through hormonal dysfunctions linked to it. Histopathological evaluation is indispensable for an exact diagnosis. Because of its rarity, there is little experience with the tumor and the histological identification is also sometimes very challenging. The tumor is occasionally associated with Peutz-Jeghers syndrome, tumor of the thyroid, or goiter. Biologically it follows a low-malignant course with a fair prognosis, long-term complex patient follow up is necessary after unilateral oophorectomy of the diseased organ.

RESUMO

INTRODUCTION The authors investigated the prevalence of depressive disorders and response to citalopram among perimenopausal women visiting menopause clinics. METHOD One hundred and eighty-five consecutive outpatients were screened using the short Beck Depression Inventory. A psychiatrist investigated persons who showed medium or severe Beck depression. In the case of DSM-IV major depressive episode, a 6-week open trial with citalopram (20-40 mg daily) was started. The 17-item Hamilton Depression Rating Scale (HDRS) measured the severity of depression at baseline and at weeks 3 and 6. The primary outcome measure was the rate of responders at weeks 3 and 6 (more than 50% drop in the total HDRS score at weeks 3 and 6 compared to baseline). RESULTS Of the 185 consecutive outpatients screened, 48 (26%) have experienced medium or severe Beck depression, and 37 of them (20%) had DSM-IV major depression. Citalopram was started in 30 patients (daily doses ranged from 20 to 40 mg) and 21 (70%) finished the trial. The rate of responders at week 3 was 7/22 (32%) and at week 6 was 13/21 (62%). CONCLUSIONS Depressive disorders are common among perimenopausal women visiting menopause clinics, and the majority of those with depression respond well to citalopram. Interdisciplinary cooperation is the key point of the detection and follow up of these patients.

RESUMO

OBJECTIVES: The authors discuss upon the changes in the two cell types involved in cell mediated immunity (Killer and Natural Killer) as a result of operation in malignant ovarian tumor atients. METHODS: They study the preoperative and postoperative cell mediated immunity of 28 malignant cystadenocarcinoma cases (FIGO stage I/a-III/c). To determine the maximum K and NK cell activity they used the kinetic model of cytotoxicity enzyme. RESULTS AND CONCLUSIONS: They conclude that operation of malignant ovarian tumors had no significant influence on K and NK cell activity. They hypothesize that unchanged cell mediated immunity seems to be independent of malignant tumors, especially in these conditions. We need further information about this change of cell mediated immunity.
