RESUMO

AIM: The aim of this study was to determine the safety of vaginal delivery with a non-vertex second twin when the first twin is in the vertex presentation. MATERIALS AND METHODS: A retrospective analysis was undertaken, utilizing a cohort of twin gestations in which the presenting twin was vertex and the second twin was either vertex (group A) or non-vertex (group B). We assessed maternal and neonatal outcomes including emergency cesarean delivery, 5-minute Apgar scores, cord arterial pH, NICU admissions, and adverse maternal postpartum outcomes including ICU admissions and the requirement of blood products. RESULTS: Six hundred and eighty-five women with a vertex presenting twin were admitted to labor and delivery. Three hundred and ninety-five women were included in group A (vertex/vertex) and 290 were included in group B (vertex/non-vertex). No statistically significant differences were found in the 5-minute Apgar scores, cord arterial pH, or in the rates of emergency cesarean deliveries, NICU admission, maternal blood transfusion or ICU admissions. CONCLUSION: In conclusion, vaginal delivery of a breech second twin when the presenting twin is vertex was found as safe as vaginal delivery of twins in the vertex/vertex presentation.

RESUMO

OBJECTIVE: Gynecologic Sarcomas are rare, aggressive tumors. The aim of this study was to explore the incidence and outcomes of gynecologic sarcomas in a large national data registry and to compare them with reports from other countries. STUDY DESIGN: Records of gynecologic sarcomas diagnosed in Israel (1980-2014) were extracted from the National Cancer Registry and classified according to International Classification of Diseases for Oncology-3 and characterized according to anatomical site, morphology and demographics. Age-standardized incidence rates and 1, 3, 5 and 10-year relative survival rates were calculated for 3 time periods (1980-1994, 1995-2001 and 2005-2014) according to patient age, stage and years of diagnosis. RESULTS: During 1980-2014, 1271 new gynecologic sarcomas were diagnosed in Israel, with incidence slightly increasing in 1980-2004, to an age-standardized incidence rate of 13 per million women. The most common histologic diagnosis was leiomyosarcoma (48%) and the most common anatomical site was the uterus (89%). The age-standardized incidence rate for uterine sarcoma is higher in Israel (10.55 per million) than in England (7.4 per million) and Germany (5.8 per million) respectively. The 5-year overall survival was significantly poorer in patients >70-years, as compared to younger patients (p<0.001) and in those with leiomyosarcoma compared to endometrial stromal sarcoma (p<0.001). The survival rate of patients with leiomyosarcoma in Israel are comparable to survival rates reported by other studies, although substantially lower regarding endometrial stromal sarcoma. CONCLUSIONS: Uterine leiomyosarcoma was the most common gynecologic sarcoma found in the Israeli, European and American registries. Older patients and those with leiomyosarcoma have the worst prognoses. Histological and anatomical variations in Israel are comparable with global statistics, but the incidence in Israel seems higher than in Europe.

RESUMO

A rapid and reliable intraoperative diagnostic technique to support clinical decisions was developed using Fourier-transform infrared (FTIR) spectroscopy. Twenty-six fresh tissue samples were collected intraoperatively from patients undergoing gynecological surgeries. Frozen section (FS) histopathology aimed to discriminate between malignant and benign tumors was performed, and attenuated total reflection (ATR) FTIR spectra were collected from these samples. Digital dehydration and principal component analysis and linear discriminant analysis (PCA-LDA) models were developed to classify samples into malignant and benign groups. Two validation schemes were employed: k-fold and "leave one out." FTIR absorption spectrum of a fresh tissue sample was obtained in less than 5 minutes. The fingerprint spectral region of malignant tumors was consistently different from that of benign tumors. The PCA-LDA discrimination model correctly classified the samples into malignant and benign groups with accuracies of 96% and 93% for the k-fold and "leave one out" validation schemes, respectively. We showed that a simple tissue preparation followed by ATR-FTIR spectroscopy provides accurate means for very rapid tumor classification into malignant and benign gynecological tumors. With further development, the proposed method has high potential to be used as an adjunct to the intraoperative FS histopathology technique.

RESUMO

Cleavage of the MUC1 glycoprotein yields two subunits, an extracellular alpha-subunit bound to a smaller transmembrane beta-subunit. Monoclonal antibodies (mAbs) directed against the MUC1 alpha-beta junction comprising the SEA domain, a stable cell-surface moiety, were generated. Sequencing of all seven anti-SEA domain mAbs showed that they clustered into four groups and sequences of all groups are presented here. mAb DMB5F3 with picomolar affinity for the MUC1 SEA target was selected for further evaluation. Immunohistochemical staining of a series of malignancies with DMB5F3 including lung, prostate, breast, colon, and pancreatic carcinomas revealed qualitative and qualitative differences between MUC1 expression on normal versus malignant cells: DMB5F3 strongly stained malignant cells in a near-circumferential pattern, whereas MUC1 in normal pancreatic and breast tissue showed only weak apical positivity of ductal/acinar cells. Humanized chimeric DMB5F3 linked to ZZ-PE38 (ZZ IgG-binding protein fused to Pseudomonas exotoxin) induced vigorous cytotoxicity of MUC1+ malignant cells in vitro. The intensity of cell killing correlated with the level of MUC1 expression by the target cell, suggesting a MUC1 expression threshold for cell killing. MUC1+ Colo357 pancreatic cancer cells xenotransplanted into nude and SCID mice models were treated with the chDMB5F3:ZZ-PE38 immunocomplex. In both transplant models, chDMB5F3:ZZ-PE38 exhibited significant in vivo anti-tumor activity, suppressing up to 90% of tumor volume in the SCID model compared with concomitant controls. The efficacy of chDMB5F3:ZZ-PE38 immunotoxin in mediating tumor killing both in vitro and in vivo strongly suggests a clinical role for anti-MUC1 SEA antibody in the treatment of MUC1-expressing malignancies.

RESUMO

Two topotecan treatment schedules in patients with recurrent epithelial ovarian cancer were evaluated. Protocol A (21 days) was 1.5 mg/m(2)/day topotecan on days 1 through 5 of a 21-day cycle; Protocol B (weekly) 4 mg/m(2) on days 1, 8, and 15 of a 28-day cycle. Efficacy was determined by clinical exam, CT scan, and CA125 levels. Forty-three patients on Protocol A and 21 on Protocol B were evaluated. As second-line treatment, Protocol A response was 9/20 (45%). Response to Protocol B was 4/17 (23.5%; NS). As third line or more, the response on Protocols A and B together was only 3/27 (11%). High-grade haematological toxicity was reported in 12/43 (27.9%) on Protocol A and 1/21 (4.8%) on Protocol B (p = 0.04). There was no difference in progression-free-intervals between schedules in second-line treatment. The weekly protocol had lower severe haematological toxicity. Clinical response in third line or more was very low.

RESUMO

OBJECTIVE: Intrauterine pressure catheter (IUPC) is the primary device used to evaluate uterine activity. In contrast to the IUPC, electrical uterine myography (EUM) enables noninvasive measurement of frequency, intensity, and tone of contractions. The aim of this study was to determine the accuracy of EUM compared to IUPC. STUDY DESIGN: EUM measured myometrial electrical activity using a multichannel amplifier and a noninvasive position sensor. In all, 47 women in labor were monitored simultaneously with an IUPC and EUM. We compared the frequency, intensity, and tone of uterine contractions between the methods. RESULTS: The correlation of the frequency, intensity, and tone of contractions between uterine electromyography and IUPC was strong with significant r values of 0.808-1 (P < .0001). CONCLUSION: Electrical uterine electromyography yields information about uterine contractility comparable to that obtained with IUPC.

RESUMO

BACKGROUND & AIMS: We aimed to study the personal compliance of physicians and nurses with recommendations for the administration of iron supplements for their own children and their compliance with the routine child and maternal health care surveillance recommended during the first year of life. METHODS: Five hundred physicians and nurses from Haifa and Tel Aviv area working in hospitals and the community were asked to answer a self administered questionnaire. The questionnaire included questions assessing their compliance (using a 100 mm analogue visual scale) with iron and vitamin A + D supplementation, immunizations and routine examinations at the child and maternal health care center for their children. RESULTS: One hundred and forty one physicians and 135 nurses (55.2%) cooperated and returned the questionnaire. We found that 41.2% of medical personnel graded their compliance with iron supplementations as 6 or less, in a scale of 0-10. Significant differences were found between the different professions. Nurses were significantly more compliant compared to physicians (54.9% of nurses reported full compliance compared to only 32.4% of physicians, (p = 0.001)). The degree of seniority also affected compliance. Specialists were significantly less compliant compared to interns (22% vs. 38.8% respectively). Certified nurses were also less compliant compared to uncertified nurses (52.9% vs. 61.5% respectively). Significant differences between physicians and nurses were also noted in A + D administration and routine health visits. Although nurses demonstrated more compliance with vaccinations these differences were not significant (p = 0.076). CONCLUSIONS: The compliance of medical staff for iron and A + D administration to their own children is poor especially among physicians.
