An ovarian adenomyoma developed in a 38-year-old infertile patient following treatment with exogenous gonadotrophins. Laparoscopic excision was performed. Histological examination showed thick muscular bundles resembling myometrium lined with endometrial glands and stroma. Gonadotrophins might be involved in the pathogenesis of extrauterine adenomyoma.

Aim:  A biopsy is often taken as part of the preoperative workup, regardless of the indication for hysterectomy. Some authors believe that dilatation and curettage is a poor diagnostic procedure for intrauterine pathologies, but dilatation and curettage has been the method of choice for obtaining an endometrial sample. The aim of this study was to investigate the concordance between endometrial histopathological diagnoses from preoperative dilatation and curettage and hysterectomy specimens. The differences between premenopausal and postmenopausal women were also investigated.

Preoperative and postoperative psychological factors, postoperative pain, analgesic consumption, treatment satisfaction were compared in patients treated with intravenous patient-controlled analgesia (IV-PCA) or intramuscular analgesics after laparoscopic ovarian cystectomy. Thirty-one women with laparoscopically operated benign ovarian cysts were recruited in Zonguldak Karaelmas University Faculty of Medicine, Department of Obstetrics and Gynecology. Postoperatively sixteen women received morphine delivered by IV-PCA pump system and 15 women were prescribed another opioid (meperidine) intramuscularly. Two weeks before and one day after the surgery, Beck Depression Inventory (BDI) and Beck Anxiety Inventory (BAI) were self-administered. Afterwards, the operation visual analog scale (VAS) and satisfaction with pain control scale were recorded. Preoperative BDI and BAI scores of both groups were comparable. Postoperative BDI (7.9 ± 7.2 versus 13.8 ± 6.9, P = 0.03) and BAI (11.4 ± 9.1 versus 17.4 ± 6.2, P = 0.045) scores were significantly lower in the IV-PCA group. Morphine usage with PCA resulted in significantly higher pain scores than equivalent doses of meperidine administered intramuscularly (2.94 ± 1.0 versus 1.67 ± 0.7, P = 0.001). Although higher pain scores were obtained from IV-PCA group, self-reported satisfaction rates were higher in this group (8.3 ± 1.1 versus 7.4 ± 1.1, P = 0.04). Involvement of patients in their pain management might increase the awareness of pain but their satisfaction about the control of postoperative pain was significantly improved.

Background and objective: The purpose of intraperitoneal local anaesthetic administration is to block visceral nociceptive conduction and to provide an additional route of analgesia. The present study evaluates the effects of sequential injections of bupivacaine on postoperative pain through a subphrenic catheter. Methods: In this double‐blinded controlled study, patients scheduled for gynaecological laparoscopy were randomly divided into two groups. One group received 20 mL of saline with 1: 200 000 epinephrine through a subphrenic catheter before the incision closure and at 4‐hourly intervals for the first postoperative 20 h. The second group received 20 mL of bupivacaine 0.125% with 1: 200 000 epinephrine at the same injection times. Postoperative pain scores and consumption of analgesics were compared. Results: There were no statistical differences in pain scores at rest or incidence of shoulder pain between the two groups, but the patients of the bupivacaine group reported lower pain scores on coughing only in the first hour postoperatively (P = 0.007). Although the patients consumed comparable amounts of metamizole and ondansetron, the number of patients requiring supplemental meperidine and flurbiprofen in the bupivacaine group were significantly lower than in the saline group (P < 0.05). Conclusions: This study demonstrates that intraperitoneal bupivacaine may reduce pain on coughing in the early postoperative period and the consumption of analgesics postoperatively. The subphrenic catheter technique had no impact upon pain at rest and shoulder‐tip pain after gynaecological laparoscopy.

Herlyn-Werner-Wunderlich syndrome (uterus didelphys, blind hemivagina and ipsilateral renal agenesis) - a case report.

Uterovaginal duplication with obstructed hemivagina and ipsilateral renal agenesis is referred to as the Herlyn-Werner-Wunderlich (HWW) syndrome. A 17 year old woman presented with right pelvic pain and dysmenorrhea, present since menarche at 13 and worsening over the past year. Ultrasound examination revealed a right pelvic mass (5×5 cm), double endometrial echoes, and hematocolpos. A right pelvic mass, agenesis of the right kidney, double uterus, and blind hemivagina with hematocolpos were detected by magnetic resonance imaging and intravenous pyelography. A right tubo-ovarian abscess with dense adhesions and a double uterus were observed on diagnostic laparoscopy. Adhesiolysis was carried out and purulent material irrigated. After a course of antibiotics, a vaginal septum resection was performed and the pyocolpos drained. She remained symptom free after four months of follow-up. Prompt and accurate diagnosis and treatment of this syndrome can significantly improve the lives of sufferers and prevent future complications.

Eikenella Corrodens, Cause of a Vulvar Abscess in a Diabetic Adult

Nefise Oztoprak; Ülkü Bayar; Güven Çelebi; Mustafa Basaran; Füsun Cömert

We report a case of Eikenella corrodens causing vulvar abscess in a diabetic patient. Eikenella corrodens is a slow growing, nonmotile, facultative anaerobic, Gram-negative bacillus which is commensal of the oral cavity, intestinal and genital tracts. The most common clinical sources of this organism are human bite wounds, head and neck infections and respiratory tract infections. In our knowledge, the presented case is the first report of Eikenella corrodens causing vulvar abscess in a diabetic patient.

Management of Fetal Bronchogenic Lung Cysts: A Case Report and Short Review of Literature

Ülkü Bayar; Varı̂m Numanoğlu; Sibel Bektas; Hakan Sade; Duygu Tatlı

Congenital malformations of the lung (CML) are rare with similar embryological and clinical spectra and could result in mortality if left untreated. Bronchogenic cysts are formed during the budding of the tracheal diverticula and ventral foregut in the embryological period. In this paper we want to present a case of bronchogenic cyst with continuous intrauterine cyst aspiration follow-up. After the baby birth was operated and the postoperative period was uneventful. The pathological examination revealed a bronchogenic cyst.

Idiopathic ileoileal invagination two days after cesarean section

Muge Harma; Mehmet Harma; Guldeniz Karadeniz; Ilker Arikan; Aykut Barut; Ülkü Bayar

Postoperative enteroenteric invagination is rare. The only previously reported case post‐cesarean was secondary to colonic adenocarcinoma. A 27‐year‐old woman with preeclampsia delivered a baby by cesarean section. On the second postoperative day, she had abdominal pain, nausea, vomiting, constipation, and distention. An abdominal x‐ray showed air‐fluid levels, while free fluid (ascites) was detected by ultrasonography. A computed tomography scan did not show the typical invagination picture. Her condition did not improve after 72 h of conservative treatment, and diagnostic laparotomy was performed. A 10 × 3‐cm ileoileal invagination 80 cm proximal to the ileocecal valve was found and manually reduced. The patient was discharged on the fifth postoperative day, and her six‐month follow‐up was normal.

Rengin Kosif; Ülkü Bayar; Mustafa Başaran; Şener Gezer; Dündar Kaçar; Aysu Kiyan

Aim: To research the relationship between diameter and length of umbilical cord and fetal and maternal parameters, with respect to postpartum period. Materials and Methods: Maternal, placental and neonatal parameters of202 women who delivered singleton delivery was filled to forms prepared previously and researched prospectively. Findings: Negative correlation was determined between maternal BMI and umbilical cord length (p=0.045, r= -0.130). Diameter of umbilical cord showed positive correlation with weight, lenght, BMI and chest circumference of newborn. Positive correlation between umbilical cord length and 5. minute Apgar score was found. Umbilical cord length showed positive correlation with placental central thickness. Umbilical cord diameter showed positive correlation with all dimensions of placenta and 5. minute Apgar score. There was a negative correlation between umbilical cord diameter and umbilical cord length (p=0.00, r= -0.227). All test scores showed statistically significant but weak correlations with umbilical cord length and diameter. Evaluating of the umbilical cord morphometry is important because of changes in umbilical cord diameter may especially affect outcome of newborn.
