Gastrointestinal (GI) perforation accounts for over 90% of acute abdomen and pneumoperitoneum. The presence of pneumoperitoneum secondary to spontaneously perforated pyometra is an interesting yet confusing finding given the absence of gast…

Background: Ovarian remnant syndrome is a rare gynecologic complication, most induced by difficult bilateral salpingo-oophorectomy (BSO) with the residual ovarian tissue on the pelvic wall. The residual ovarian tissue may eventually cause m…

Intrauterine devices (IUDs) provide highly effective, long-term, safe, reversible contraception, and are the most widely used reversible contraceptive method worldwide. The levonorgestrel-releasing IUD (LNG-IUD), originally designed for lon…

Ovarian remnant syndrome (ORS) is a rare, but well-known gynecological complication, most often induced by difficult bilateral salpingo-oophorectomy (BSO) procedures that leave residual ovarian tissue on the pelvic wall. The most common pre…

A 40-year-old woman visited our hospital with asymptomatic macroscopic hematuria. A nonpapillary ureteral tumor protruding from the left orifice was identified by cystoscopy. Computed tomography revealed left hydronephrosis due to the urete…

Abdominal pain with an associated pelvic mass is a common problem in everyday practice. Concerns about ectopic pregnancy, torsion of an enlarged ovary or malignancy usually dominate the diagnostic evaluation. On physical and imaging examina…

Sequential Management with Gonadotropin-Releasing Hormone Agonist and Dienogest of Endometriosis-Associated Uterine Myoma and Adenomyosis

PURPOSE: Uterine leiomyomas are the most common benign tumors of reproductive age women, but there is no effective medical therapy to data. Aim of this study was to examine and compare the efficacy of gonadotropin-releasing hormone agonist …

BACKGROUND: Because of its low incidence, medical treatment of has not yet been well established although surgical excision is generally considered effective. We report the first case of primary bladder endometriosis successfully managed wi…

ObjectiveImpaired sensitivity of endometrial tissue to spontaneous apoptosis in women with endometriosis contributes to the abnormal implantation and growth of endometrium at ectopic sites. Our purpose was to examine the effect of gonadotro…

Changes in serum glucose levels were examined in a female with insulin-independent diabetes who received a gonadotropin-releasing hormone (GnRH) analog treatment for pelvic endometriosis. The mean blood glucose levels were higher on buserel…

Levels of CA125, CA72-4 and CA19-9, serum markers for ovarian cancer, were measured throughout menstrual cycles in a patient with probable pelvic endometriosis. The patient had CA125 levels >1000 U ml(-1), CA72-4>10 U ml(-1) and CA19-9>150 …

Rabbit uterus contains type I and II oestrogen binding sites in the cytosol, and nuclear fractions. Oestrogen-stimulated increase in uterine weight was inhibited by concurrent treatment with progesterone or danazol. Oestrogen-induced type I…
