    Bloody Nipple Discharge As A Benign, Self-Limiting Disorder in Young Children: A Systematic Review Including Two Related Case Reports
    (2015) Acer, Tugba; Derbent, Murat; Hicsonmez, Akgun; 0000-0001-5391-9094; 26410727; E-4455-2019
    Background/purpose: Bloody nipple discharge (BND) is rare, distressing for parents, and presents a challenge for physicians. Methods: We used PubMed to search for cases of BND that were diagnosed before adolescence and added data from two of our cases. Results: The analyzed cohort comprised 46 patients (28 boys and 18 girls; mean [SD] age, 12.5 +/- 13.3 months; range, 20 days to 4 years). The mean time for spontaneous resolution was 2.8 +/- 2.4 months (range, 1 week to 8 months) after onset of BND without any intervention. The diagnosis was mammary ductal ectasia (MDE) in 15 patients, gynecomastia with MDE in two patients, hemorrhagic cysts in two patients, and gynecomastia alone in one patient. The majority (89.3%) of patients <1 year old were managed conservatively, but half of them aged >1 year (50.0%) underwent surgery. Surgery was performed more often in patients in whom a mass had been identified. Conclusions: Age and findings at physical examination affect selection of treatment, but not sex. We found no reported cases of malignancy. Symptoms in children who are managed conservatively resolve within 10 months. Children with BND should be conservatively managed to avoid the risk of developing breast deformities before adolescence. (c) 2015 Elsevier Inc. All rights reserved.

    The Effect of Intraperitoneal N-Acetylcysteine on Postoperative Adhesions in Rat Models
    (2017) Asian, Gizem Inal; Otgun, Ibrahim; Acer, Tugba; Tepeoglu, Merih; Hicsonmez, Akgun; https://orcid.org/0000-0002-9894-8005; 28874629; AAK-5222-2021
    ATM: In this study, we researched the effect of local administration of N-acetylcysteine (NAC) on postoperative intra-abdominal adhesion formation in the rat models. METHODS: 20 female Wistar Albino rats which were 5-7 months old are used for the study. The rats were divided into two equal groups. Group one was administered saline solution (n=10) while group two was administered NAC (n=10) after caecal abrasion. They were dissected on postoperative tenth day and were examined macroscopically and microscopically for the adhesion formation. Intraperitoneal adhesion formation was scored blinded with Evans model. The most adherent bowel section was excised for histopathologic examination. Mann Whitney U test were used for statistical analysis. RESULTS: In Group one, all rats have had adhesions. None of the rats in Group two had either severe inflammatory cell reaction or dense interstitial fibrosis. Macroscopic adhesion formation and microscopic inflammatory cell reaction and interstitial fibrosis formation after surgery were less at the group two (NAC applied) (p<0.05, p<0.05, p<0.05). CONCLUSION: We believe that the intraperitoneal single dose usage of NAC may be promising for decreasing the postoperative intraabdominal adhesions.

    The Separation of The Epididymis and The Abnormal Attachment of The Gubernaculum Cause Undescendence in The Rat Testes
    (2014) Acer, Tugba; Hicsonmez, Akgun; https://orcid.org/0000-0001-5391-9094; 25217829; E-4455-2019
    Epididymal anomalies are common in cryptorchid patients. This led us to consider that anomalies of the epididymis, to which the gubernaculum is attached, or abnormal attachment of the cranial end of the gubernaculum, could lead to cryptorchidism. Twenty-eight male Sprague-Dawley rats were divided into two groups: In Group 1 rats (n = 14), the epididymis was isolated from the testis, and in Group 2 rats (n = 14), the gubernaculum was isolated from the epididymis and re-attached to the tail of the epididymis. In both groups, the non-operated testes were used as the control. In Group 1, cryptorchidism rates were 1/14 in the control testes and 8/14 in the operated testes (p < 0.01). In Group 2, cryptorchidism rates were 0/13 in the control testes and 6/13 in the operated testes (p < 0.01). Cryptorchidism was seen when the epididymis was loosely or non-connected to the testis and the gubernaculum was attached solely to the epididymis (mimicking anomalies of ductal fusion) and when the gubernaculum was attached to the tail of the epididymis (mimicking anomalies of ductal suspension). Therefore epididymal anomalies and abnormal attachment of the gubernaculum may play a role in the undescendence of the testes in the rats.
