    A rare cause of glans penis masses in childhood: Fibroepithelial polyp
    (Medknow Publications, 2014) Sencan A.; Sencan A.; Gunsar C.; Cayirli H.; Nese N.
    Fibroepithelial polyps of glans penis are very rarely seen in childhood. A 6-month-old male admitted to our institution with a slowly enlarging glans penis mass on the ventral side of the glans penis. The mass was totally excised, and hystopathological diagnosis was a fibroepithelial polyp. All of the reported cases published previously, except one, are of adult age and all of them have been associated with the history of long-term condom catheter use. The presence of the case in childhood; however, suggests that the pathology might be congenital. This is the second pediatric case presented in the English literature.

    Sonic hedgehog, TBX18, and TSHZ3 proteins involved in pyeloureteral motility development are overexpressed in ureteropelvic junction obstruction: An immunohistochemical, histopathological, and clinical comparative study
    (Saudi Arabian Armed Forces Hospital, 2016) Yilmaz O.; Nese N.; Dalgic M.; Kesici G.P.; Genc A.; Taneli C.; Gunsar C.; Sencan A.; Cayirli H.; Isisag A.
    Objectives: To compare pathological samples obtained from cases that underwent surgery for ureteropelvic junction (UPJ) obstruction with samples obtained during autopsies of subjects. Methods: Retrospectively, 42 patients who had undergone surgery due to UPJ obstruction (group 1) were included in the study. Histopathological and immunohistochemical features for sonic hedgehog (SHH), TBX18, and TSHZ3 of UPJ were evaluated and findings were compared with 20 autopsy cases (group 2). Original Articles Results: In group 1, the scores were statistically significantly higher in terms of cytoplasmic SHH, nuclear TBX18, cytoplasmic and nuclear TSHZ3 staining. Statistically, no correlation was found between age and the staining scores belonging to these 3 antibodies in group 1 and group 2. Intense inflammation was found to be related with nuclear staining for TBX18. Conclusion: Gene product expressions of SHH, TBX18 and TSHZ3 are statistically higher in patients with UPJ obstruction, when compared with control group. The explanation may be the reactivation of the processes, which had shown their effects in the embryological period, due to the chronic inflammation and long-term micro-trauma created by the disease. © 2016, Saudi Arabian Armed Forces Hospital.

    Central Precocious Puberty Secondary to Adrenocortical Adenoma in a Female Child: Case Report and Review of the Literature
    (Elsevier USA, 2017) Ersoy B.; Kizilay D.; Cayirli H.; Temiz P.; Gunsar C.
    Background Pediatric adrenocortical tumors are rare but significant causes of virilization and peripheral precocious puberty (PPP). Case A 4-year-old girl presented with development of breast, pubic hair, and facial acne. Her bone age was advanced, and her gonadotropin level did not elevate in a gonadotropin-releasing hormone (GnRH) test. High levels of dehydroepiandrosterone sulfate, estradiol, and testosterone, and detection of a tumor in the left adrenal gland of the abdomen using computed tomography led to a diagnosis of PPP due to adrenal tumor. Adrenal adenoma was diagnosed with pathology after the tumor was removed. Ultrasonography detected multicystic ovaries before surgery. Although the androgen levels decreased, high estrogen levels persisted after complete tumor resection. Approximately 1 year after the surgery, the patient's breast development persisted, bone age progressed rapidly, and gonadotropin levels increased in a GnRH test. Central precocious puberty was diagnosed, and treatment with GnRH analogues was started. Summary and Conclusion Adrenal adenoma might present with isosexual PPP as well as virilization in girls. The ovaries should be carefully assessed in these patients. Prolonged exposure to androgen and estrogen might cause ovarian multicysts leading to persistence of high estrogen levels and initiation of central precocious puberty. © 2017 North American Society for Pediatric and Adolescent Gynecology

    Successful outcomes in laparoscopic pyeloplasty using knotless self-anchoring barbed suture in children
    (Elsevier Ltd, 2019) Yilmaz O.; Tanriverdi H.I.; Cayirli H.; Ertan P.; Sencan A.; Genc A.; Taneli C.
    Introduction: Laparoscopic pyeloplasty for ureteropelvic junction obstruction in children has gained increasing importance over the last decade. Intracorporeal knot tying still remains a technical challenge for the surgeon. Self-anchoring suture incorporates a new concept for tissue approximation and reduces intracorporeal knot tying problems. There are very few reports on self-anchoring knotless suture and its application for laparoscopic pyeloplasty in children. We present our results of a series of consecutive children undergoing laparoscopic pyeloplasty with knotless barbed sutures. Material and method: We prospectively evaluate 15 consecutive patients who underwent laparoscopic pyeloplasty with knotless barbed sutures (V-LocTM, Covidien) for ureteropelvic anastomosis. The decision of the operation was given by pediatric nephrology-urology-radiologic imaging diagnostic team, and all patients were operated by a single surgeon. Pyeloplasty was performed without pelvic reduction, and the anastomosis was made by barbed sutures using running fashion. Results: The mean age of the patients were 5.39 (3 months-17 years). Two cases had undergone a right-sided pyeloplasty, and thirteen had undergone a left-sided pyeloplasty. The duration of the operative procedure was 60–110 min. Neither intraoperative nor postoperative complication was encountered in any of the cases. Patients were followed by ultrasonographic evaluation. The anteroposterior diameter (AP) diameter of renal pelvis and hydronephrosis grade Society for Fetal Urology (SFU) are significantly different when compared with pre-operative and postoperative period (p = 0.001 and p = 0.001, respectively). Owing to the renal parenchymal thickness change by age pre-operative and postoperative thickness comparison is adjusted by age, because age is considered as a covariate (confounder variable). We observed statistically significant (p = 0.003) difference in parenchymal thickness in all cases. Follow-up periods of the 15 consecutive pediatric pyeloplasty cases were 6–54 months. Conclusion: In the present study, successful outcome of the laparoscopic pyeloplasty using barbed suture was shown for the first time in children in literature. We believe that successful outcome of laparoscopic pyeloplasty could be achieved by eliminating knots and less manipulation on the wound edge also minimizes tissue injury during the procedure.[Formula presented] [Table presented] © 2019 Journal of Pediatric Urology Company
