Publication RETROSPECTIVE ANALYSIS OF BORDERLINE OVARIAN TUMORS: OUTCOMES AT A SINGLE CENTER(2019-03-01T00:00:00Z) YILMAZ, ERCAN; Sahin, NURHAN; KÖLELİ, IŞIL; MELEKOĞLU, RAUF; Tanrikut, Emrullah; Faydali, Simge; KARAER, ABDULLAH; Coskun, Ebru Inci; ŞAHİN, NURHANWe wanted to discuss our experiences in the approach to borderline ovarian tumors, which constitute a group different from epithelial ovarian tumors with respect to their biological structure in line with retrospective information gathered from our cases. A total of 25 patients operated on for the indication of adnexal masses diagnosed as borderline ovarian tumors based on frozen section results were included in our study. Patient age, tumor diameter, tumor markers and surgeries performed were discussed in the light of the literature. Statistical analyses were performed using the SPSS software. The patient mean age was 43.84 +/- 11.34 years. The mass was localized in the right (n=13), left (n=11) or both (n=1) adnexal regions. The mean tumor diameter was 12.9 +/- 5.84 cm. Histopathologic examination established the diagnosis of serous borderline (n=14 patients) and mucinous borderline (n=11) ovarian tumors. Although the results of our study are consistent with current literature data, a greater number of current studies should be performed on borderline ovarian tumors, which are defined as a class of tumors different from epithelial ovarian tumors.Publication Cytological and cytomorphometric characteristics of buccal mucosa cells from smokeless tobacco users(2017-11-01T00:00:00Z) Dagli, Adile Ferda; Sahin, NURHAN; Bozdag, Zehra; Ucer, Ozlem; AKATLI, AYŞE NUR; Artas, Gokhan; Sahin, Ibrahim; Yardim, Meltem; Dalkilic, Semih; Akkoc, Ramazan Fazil; Simsek, Sercan; Aydin, Suleyman; ŞAHİN, NURHANBackgroundUse of smokeless tobacco (ST) is increasing in many communities. We investigated whether ST alters the cytological and cytomorphometric features of buccal mucosa cells.Publication Clinical and Pathological Findings on Intoxication by Yellow Phosphorus After Ingesting Firework Cracker: A Rare Case of Autopsy(2016-01-01T00:00:00Z) Samdanci, Emine Turkmen; Cakir, Ebru; Sahin, NURHAN; Elmali, Candan; Sayin, Sadegul; ŞAHİN, NURHANYellow phosphorus is a toxic substance used in the production of firework cracker, fireworks, ammunition and agricultural dung. When ingested, it shows its effects mainly in the liver, the kidneys, and the brain. A four-year-old girl had died as a result of acute hepatic failure caused by ingesting a firework cracker. The case showed high levels of hepatic enzymes, along with non-specific signs such as nausea, vomiting and diarrhea. Autopsy revealed diffuse microvesicular steatosis in the liver and disseminated degeneration in the proximal tubules of the kidneys. In cases with concomitant hepatorenal failure and cardiovascular collapse, death is inevitable. However, when only hepatic failure develops, hepatic transplantation may be lifesaving. Although intoxication from ingesting yellow phosphorus has a very high rate of mortality, forensic cases are extremely rare in the literature.Publication Vulvar vestibular papillomatosis(2012-12-01T00:00:00Z) Bilgic, Ozlem; Karincaoglu, Yelda; Sahin, NURHAN; ŞAHİN, NURHANVestibular papillomatosis (VP) is a benign, asymptomatic anatomical condition present in approximately 1% of women. It is characterized by linear, pink, smooth or filiform papules symmetrically distributed on the vulva. The clinical resemblance of VP to genital warts may lead to unnecessary laboratory tests and treatments. This report presents four cases of VP in order to call attention to this entity (Turkderm 2012; 46: 220-2)Publication CD47 expression in urothelial carcinoma and its correlation with histopathological findings.(2023-11-30) Çoban G.; Yıldız P.; Şahin N.; Ersöz C.; Toprak A.; Ünver N.; Elagöz Ş.; ÇOBAN, GANİME; ŞAHİN, NURHAN; ERSÖZ, CEVPERPublication Report of a Case of Signet Ring Carcinoma Presenting as Gastric Mucosal Thickening: A Diagnostic Dilemma(2021-01-01T00:00:00Z) Karatoprak, Cumali; Akçakaya, Adem; Şentürk, Hakan; Çoban, Ganime; Şahin, Nurhan; Türk, Hacı Mehmet; KARATOPRAK, CUMALİ; AKÇAKAYA, ADEM; ŞENTÜRK, HAKAN; ÇOBAN, GANİME; ŞAHİN, NURHAN; TÜRK, HACI MEHMETThe number of cancer cases has been increasing worldwide. Early diagnosis and tumor resection remain as the most effective treatments for gastric cancer. However, early diagnosis is not always possible as it is frequently not possible to make treatment decisions without pathologic diagnosis in patients with clinically suspected cancer. This causes delays in diagnosing cancer. We presented a 58 years old woman with gastric signet ring cell carcinoma that could not be diagnosed despite using four different methods of stomach biopsies. We aimed to emphasize that despite the use of advanced methods, if clinical cancer in non-diagnosed cases is suspected, we should be more aggressive for early diagnosis.Publication A milia en plaque case(2018-01-01T00:00:00Z) Cenk, Hulya; SARAÇ, GÜLBAHAR; Sahin, NURHAN; ŞAHİN, NURHANPublication Total Surgical Excision by Ultrasound-Guided Wire Localization for Spontaneous Abdominal-Wall Endometriosis(2019-12-03T00:00:00Z) TAKMAZ, TAHA; KIRAN, Gürkan; ÖZCAN, PINAR; Sahin, NURHAN; Tanoglu, Basak; TAKMAZ, TAHA; KIRAN, GÜRKAN; ÖZCAN, PINAR; ŞAHİN, NURHANBackground: Extrapelvic endometriosis is the most-common form of abdominal-wall endometriosis (AWE). This rare condition usually results from transport of endometrial tissue into incision sites of surgical operations or adjacent tissues. Spontaneous AWE also occurs. A common symptom is a painful and tender mass usually associated with menstruation. Noncyclic pain can occur in 45% of patients. Standard treatment is complete surgical excision. Case: This 44-four-year-old patient, gravida 0, presented with persistent cyclic pain in her right inguinal area, but she had no history of previous abdominal surgery Ultrasonography (USG) showed an obscure, heterogeneous-hypoechogenic mass of similar to 2.0 x 1.5 cm in the right lower quadrant of her abdominal wall. She underwent total surgical excision by ultrasound-guided-wire localization. Results: The nonpalpable mass that was localized via an ultrasound-guided wire was surgically excised. A diagnosis of AWE was confirmed by histopathologic examination of the mass. Two months postoperatively, this patient-s pain disappeared. Conclusions: Extrapelvic endometriosis can be located in almost any organ of the body, including the abdominal wall. The incidence of AWE is reported to be up to 0.03%-3.5%, and most cases of AWE commonly arise in an incision made during a cesarean section. Spontaneous AWE is less common, compared to cesarean-scar endometriosis. The diagnosis of AWE is difficult due to its rarity, subclinical presentation, and generally nonpalpable lesions. Ultrasound-guided-wire localization is a reliable, simple, and practical solution for localizing nonpalpable lesions.Publication The Effect of Bemiparine Na and Hyaluronic Acid on Postoperative Adhesions in Rat Uterine Horn Model(2022-03-14) Baydemir S.; Gökmen Karasu A.
