Background: Abnormal uterine bleeding is defined as any alteration in the pattern or volume of menstrual blood flow, and it is preferably treated using hysterectomy, endometrial destruction or the levonorgestrel-releasing intrauterine system (Mirena(®) ). Recently, it has been demonstrated that studies of Mirena(®) were generally small and consequently imprecise.

Aims: Our study was aimed at assessing the effects of a slow-release levonorgestrel (20 μg/day) intrauterine device in fertile and postmenopausal women experiencing abnormal uterine bleeding that did not respond to traditional medical management.

Background/purpose: The stripping of benign ovarian cysts has been reported to be preferable to cyst wall ablation. The procedure can be performed via either an open or laparoscopic approach. The aim of our study was to evaluate the efficacy of the technique of stripping performed by laparoscopy and laparotomy in the treatment of benign ovarian masses in the pediatric age group with respect to healthy ovarian tissue.

This report presents the uncommon case of a 154-day delayed delivery in a spontaneous twin pregnancy associated with uterine atony. After abortion of the first fetus at 16 weeks, a healthy male was born at 38 weeks. Postpartum hemorrhage due to uterine atony, which was successfully treated with prostaglandins, occurred.

Aim: The aim of our study was to evaluate the efficacy of the laparoscopic stripping technique on benign ovarian masses with respect to healthy ovarian tissue.

Material And Methods: Seventy-six patients between 14 and 40 years of age were enrolled after receiving a diagnosis of mono-lateral ovarian cyst and underwent laparoscopic surgery for cyst excision with the stripping technique. Histological observations of these specimens were then performed and graded on a semiquantitative scale.

Objective: Endometrial hyperplasia without cytological atypia is commonly treated with progestins, but other treatment regimes may be available with equivalent efficacy and low side effects.

Design: A randomized double-blind, placebo and progesterone-controlled clinical trial to evaluate the effects of genistein aglycone in reducing endometrial hyperplasia.

Patients: A group of 56 premenopausal women with non-atypical endometrial hyperplasia were enrolled and received: genistein aglycone (n=19; 54 mg/day); norethisterone acetate (n=19; 10 mg/day on days 16-25 of the menstrual cycle) or placebo (n=18) for 6 months.

Introduction: Wnt-1 is capable of inducing metanephric mesenchyme to undergo tubulogenesis. A relationship between the degree of cystogenesis and reduced E-cadherin (E-cad) expression was described. Syndecan-1 (Sdc-1) has a critical role in kidney development.

Introduction and Aim. Disorders of esophageal motility causing dysphagia and gastroesophageal reflux are frequent in survivors to esophageal atresia (EA) and distal tracheoesophageal fistula (TEF). The aim of the present study was to investigate the histologic and immunohistochemical features in both esophageal atretic segments to further understand the nature of the motor disorders observed in these patients.

Purpose: Dextranomer/hyaluronic acid implantation is associated with a granulomatous inflammatory reaction, replaced by fibrosis. Appearance of myofibroblasts is considered a crucial event in fibrosis, and CD68 positive cells and other factors are implied in their activation. Mast cells are a source of these factors and tryptase can induce fibroblast to express alpha-smooth muscle actin, which is characteristic of myofibroblasts.

Background: Stripping of the cystic wall is performed by gynecologists to treat large ovarian cysts. Information in the pediatric population is poor. We prospectively evaluated the pathologic specimens of large ovarian cyst to determine whether the stripping technique is a tissue-sparing procedure even in this age.

Background: Occult hepatitis B virus (HBV) infection frequently occurs in patients with HBV surface antigen (HBsAg)-negative chronic liver disease, and much evidence suggests that it is a risk factor for hepatocellular carcinoma (HCC) development. However, to the authors' knowledge, no follow-up study has been performed to date evaluating HCC occurrence over time in chronic hepatitis patients with or without occult HBV infection.

Methods: A cohort of the 380 HBsAg-negative chronic hepatitis patients attending the study institution between 1991-2000 were evaluated and tested for occult HBV DNA by analysis of liver biopsy specimens.

We report a case of severe hepatotoxicity associated with ductopenia in a 61-year-old woman. The patient developed jaundice, vomiting, and abdominal pain a few weeks after the beginning of treatment with candesartan cilexetil, 16 mg/d, for essential hypertension. Liver biopsy showed parenchymal bilirubinostasis with portal cholangitis and ductopenia.
