Choriocarcinoma is the most malignant tumor of gestational trophoblastic disease arising from any gestation. It has a tendency toward relapse as well as metastasis. Here, a case of relapsed high-risk choriocarcinoma (FIGO stage IV, WHO score 12) in a 37-year-old female presenting with vaginal bleedings is described. Relapse developed at the site of the surgical scar from hysterectomy that had been performed 2 years earlier. Although the patient was treated with aggressive chemotherapy, she was in a bad general condition and died from infection and liver insufficiency. © 2013 S. Karger AG, Basel.

Background: Our aim was to study the effect of GnRH agonist and antagonist protocols of ovarian stimulation on oxidative stress parameters in serum and the influence of oxidative stress parameters change on the outcome of IVF cycles. Methods: This prospective study included 82 patients who un der went IVF procedures. We determined SOD, MDA and SH groups in serum. Serum samples were obtained between the second and fourth day of the cycle and on the day of HCG administration during ovarian stimulation. Results: Patients were divided into two groups depending on the protocol of stimulation. The mean total and mature oocytes number and number of fertilized oocytes were higher in GnRH agonist group. There was no significant difference in biochemical pregnancy, miscarriage and live -birth rate in both groups. Mean serum SOD was significantly lower, while mean serum MDA and SH groups were significantly higher after ovarian stimulation. Delivery rate was higher in patients without OS while miscarriage rate was higher in patients with OS. Conclusions: Our study confirmed that there is a difference in the concentration of oxidative stress parameters before and after ovarian stimulation. IVF outcome is better in patients without OS after ovarian stimulation. However, the protocol of ovarian stimulation is neither associated with a change in oxidative stress parameters nor with the outcome of ART procedures. © 2017 by Lidija Tulić.

Introduction Uterus didelphys with obstructed hemivagina and ipsilateral renal agenesis represents a complex congenital anomaly, also known in the literature as Herlyn-Werner-Wunderlich (HWW) syndrome. Case Outline A 16-year-old patient presented with secondary amenorrhoea and abdominal pain. Her history revealed anorexia nervosa; she had menarche at the age of 14; her menstrual cycles were regular, with progressive dysmenorrhoea. Nine months after the explorative laparotomy performed at the regional healthcare center there was no a definitive diagnosis. Pelvic examination showed a paravaginal pelvic mass located on the right side. Magnetic resonance imaging of the abdomen and pelvis confirmed the diagnosis of HWW syndrome. Transvaginal excision and marsupialisation of the vaginal septum were performed. Regular menstrual cycles were resumed after four years following the treatment of anorexia nervosa. Twelve years after the operation, the patient conceived spontaneously; pregnancy developed in the left non-obstructed uterus. She underwent Cesarean section at the 37th gestational week and gave birth to a healthy female infant. Conclusion HWW syndrome is an uncommon cause of abdominal pain and progressive menstrual discomfort shortly after menarche. It is therefore essential to maintain a high index of suspicion of the existence of this syndrome in such cases, since prompt and adequate treatment prevents the development of complications and allows for preservation of the reproductive potential of both hemi-uteri.
