BACKGROUND Ovarian and uterine carcinomas are the most common cause of cancer-related deaths in gynecological malignant diseases. We aimed to assess whether the L1 adhesion molecule, an important mediator for cell migration for neural and tumour cells, is expressed in these carcinomas. METHODS We investigated L1 expression by immunohistochemistry, RT-PCR,(More)
Hydatidiform mole with co-existing live fetus is a rare entity. Two cases are reported. In the first, complete mole with a co-existing live fetus was suspected on ultrasound examination at 16 weeks of gestation. A termination of pregnancy was performed due to early onset of severe preeclampsia and thyrotoxicosis. In the second case, the patient was admitted(More)
BACKGROUND Despite the excellent prognosis of Fédération Internationale de Gynécologie et d'Obstétrique (FIGO) stage I, type I endometrial cancers, a substantial number of patients experience recurrence and die from this disease. We analyzed the value of immunohistochemical L1CAM determination to predict clinical outcome. METHODS We conducted a(More)
STUDY OBJECTIVE To assess obstetric performance and fetal outcomes after laparoscopy or laparotomy performed during pregnancy. DESIGN Nationwide, multicenter, retrospective chart review (Canadian Task Force classification II-2). SETTING Seventeen hospitals throughout Israel: 12 university or university-affiliated hospitals and 5 general hospitals. (More)
Apoptosis and the apoptosis-related proteins (ARP) (Fas, Fas ligand (FasL), bcl-2 and p53) were analyzed in macrophages of different human ovarian epithelial tumors. Few macrophages were found in ovaries of women without oncologic disorders. In ovarian benign cysts, macrophagic density reached 4.9+/-1.2 per 50,000 microm2, most were present in(More)
OBJECTIVES To determine the pre-malignant and malignant potential of endometrial polyps and to assess whether different clinical parameters are associated with malignancy in the polyps. STUDY DESIGN Four hundred and thirty consecutive cases of hysteroscopic diagnosis of endometrial polyp were retrieved. The medical records, preoperative vaginal sonography(More)
OBJECTIVE To determine whether pituitary down-regulation after gonadotropin-releasing hormone analogue (GnRH-a) administration can be accurately predicted by transvaginal ultrasonographic measurement of endometrial thickness. DESIGN Prospective study. SETTING An IVF unit of an academic medical center. PATIENT(S) One hundred eighty-one patients(More)
L1 cell adhesion molecule (CD171) represents a strongly unfavorable prognostic biomarker for ovarian and endometrial carcinomas. Here we carried out an immunohistochemical survey of L1 expression in normal adults and in a broad range of benign and malignant tumors using monoclonal antibody L1-11A and the novel monoclonal antibody L1-14.10. In normal(More)
Persistent trophoblastic activity after salpingostomy for ectopic pregnancy implies the presence of intra-abdominal trophoblastic tissue, usually within the fallopian tube. We report a case of disseminated trophoblastic peritoneal implants, presenting as hemoperitoneum three weeks after laparoscopic salpingectomy. Only 23 such cases have been reported.(More)
The objective of the study was to compare the outcome measures of patients with endometrial adenocarcinoma diagnosed by endometrial biopsy, uterine curettage, or hysteroscopy. Medical records of 392 women diagnosed with apparent early-stage endometrial adenocarcinoma were reviewed. Data concerning the mode of diagnosis, histologic type and grade, surgical(More)
