Viral Hepatitis Special
    Background/Aims: This study aimed to evaluate the real-life efficacy and tolerability of direct-acting antiviral treatments for patients with chronic hepatitis C (CHC) with/without cirrhosis in the Turkish population. Material and Methods: A total of 4,352 patients with CHC from 36 different institutions in Turkey were enrolled. They received ledipasvir (LDV) and sofosbuvir (SOF)+/- ribavirin (RBV) ombitasvir/paritaprevir/ritonavir +/- dasabuvir (PrOD)+/- RBV for 12 or 24 weeks. Sustained virologic response (SVR) rates, factors affecting SVR, safety profile, and hepatocellular cancer (HCC) occurrence were analyzed. Results: SVR12 was achieved in 92.8\% of the patients (4,040/4,352) according to intention-to-treat and in 98.3\% of the patients (4,040/4,108) according to per-protocol analysis. The SVR12 rates were similar between the treatment regimens (97.2\%-100\%) and genotypes (95.6\%-100\%). Patients achieving SVR showed a significant decrease in the mean serum alanine transaminase (ALT) levels (50.90 +/- 54.60 U/L to 17.00 +/- 14.50 U/L) and model for end-stage liver disease (MELD) scores (7.51 +/- 4.54 to 7.32 +/- 3.40) (p<0.05). Of the patients, 2 were diagnosed with HCC during the treatment and 14 were diagnosed with HCC 37.0 +/- 16.0 weeks post-treatment. Higher initial MELD score (odds ratio {[}OR]: 1.92, 95\% confidence interval {[}CI]: 1.22-2.38

    (INT SOC ADVANCEMENT SPINE SURGERY-ISASS, 2019-01-01) Karabulut, Cem; Ayhan, Selim; Yuksel, Selcen; Nabiyev, Vugar; Vila-Casademunt, Alba; Pellise, Ferran; Alanay, Ahmet; Sanchez Perez-Grueso, Francisco Javier; Kleinstuck, Frank; Obeid, Ibrahim; Acaroglu, Emre; Grp, European Spine Study
    Background: Treatment of adult spinal deformity (ASD) in elderly patients remains controversial. The aim of this study was to identify the factors leading to the surgical treatment by comparing the baseline characteristics of operative versus nonoperative patients, to evaluate the safety and efficacy of surgery, and to compare operative and nonoperative management of elderly ASD patients at the end of the 2-year follow-up period. Methods: Retrospective review of a multicenter, prospective ASD database was performed. Patients over 70 years of age with ASD who were scheduled to undergo surgical treatment and who were treated and/or followed without surgical intervention participated in the study. Demographic, clinical, surgical, and radiological characteristics and health-related quality-of-life (HRQOL) (Core Outcome Measures Index {[}COMI], Oswestry Disability Index {[}ODI], Short-Form-36 Mental Component Summary {[}SF-36 MCS], Short-Form-36 Physical Component Summary {[}SF36-PCS], and Scoliosis Research Society-22 {[}SRS-22]) parameters of such group of patients were evaluated pre-and posttreatment. Results: A total 90 patients (females: 71, males: 29

    The Influence of Diagnosis, Age, and Gender on Surgical Outcomes in Patients With Adult Spinal Deformity
    (SAGE PUBLICATIONS LTD, 2018-01-01) Ayhan, Selim; Yuksel, Selcen; Nabiyev, Vugar; Adhikari, Prashant; Villa-Casademunt, Alba; Pellise, Ferran; Sanchez Perez-Grueso, Francisco; Alanay, Ahmet; Obeid, Ibrahim; Kleinstueck, Frank; Acaroglu, Emre; Grp, European Spine Study
    Study Design: Retrospective review of prospectively collected data from a multicentric database. Objectives: To determine the clinical impact of diagnosis, age, and gender on treatment outcomes in surgically treated adult spinal deformity (ASD) patients. Methods: A total of 199 surgical patients with a minimum follow-up of 1 year were included and analyzed for baseline characteristics. Patients were separated into 2 groups based on improvement in health-related quality of life (HRQOL) parameters by minimum clinically important difference. Statistics were used to analyze the effect of diagnosis, age, and gender on outcome measurements followed by a multivariate binary logistic regression model for these results with statistical significance. Results: Age was found to affect SF-36 PCS (Short From-36 Physical Component Summary) score significantly, with an odds ratio of 1.017 (unit by unit) of improving SF-36 PCS score on multivariate analysis (P < .05). The breaking point in age for this effect was 37.5 years (AUC = 58.0, P = .05). A diagnosis of idiopathic deformity would increase the probability of improvement in Oswestry Disability Index (ODI) by a factor of 0.219 and in SF-36 PCS by 0.581 times (P < .05). Gender was found not to have a significant effect on any of the HRQOL scores. Conclusions: Age, along with a diagnosis of degenerative deformity, may have positive effects on the likelihood of improvement in SF-36 PCS (for age) and ODI (for diagnosis) in surgically treated patients with ASD and the breaking point of this effect may be earlier than generally anticipated. Gender does not seem to affect results. These may be important in patient counseling for the anticipated outcomes of surgery.

    Management of neuroendocrine carcinomas of the breast: A rare entity
    (SPANDIDOS PUBL LTD, 2011-01-01) Yildirim, Yesim; Elagoz, Sahende; Koyuncu, Ayhan; Aydin, Cengiz; Karadayi, Kursat
    Neuroendocrine (NE) carcinoma of the breast is extremely rare and constitutes less than 0.1\% of all breast tumors. Only a few studies are currently available in the literature and a standard approach to treating this tumor has yet to be established. The aim of this study was to apply pathological treatment modalities in clinical practice and to select the most appropriate treatment accordingly. Six female patients were diagnosed with primary NE carcinoma of the breast. The patients underwent modified radical mastectomy with axillary dissection. Pathological specimens were stained with hematoxylin and eosin and an immunohistochemical panel of antibodies {[}neuron-specific enolase (NSE), chromogranin, synoptophysin, estrogen and progesterone receptor, c-erbB2 and Ki-67]. The results showed that tumor size ranged from 2 to 4.5 cm in diameter. Lymph node metastasis was detected in 4 (67\%) patients. Estrogen and progesterone receptor expression was found in 5 (83\%) patients. None of the patients expressed c-erbB2. Chromogranin was found to be positive in 5 (83\%) patients. Synoptophysin expression was detected in 5 (83\%) patients. NSE was stained in 4 (67\%) patients. An intraductal component was found in 5 (83\%) patients. Lymphovascular invasion was found in 5 (83\%) patients. Adjuvant chemotherapy was administered to patients with a Ki-67 index of >= 10\%. Radiotherapy was administered to 4 (67\%) patients, and 4 (67\%) patients received hormonal therapy. The mean follow-up time was 31.1 months (range 12-52). All 6 patients survived, although following chemotherapy and tamoxifen, the disease progressed in 1 patient who received second-line hormonal therapy. In conclusion, NE carcinoma of the breast is a distinct entity. Management of this rare tumor may include surgery and radiotherapy depending on the size of the tumor and lymph node status. However, the exact role of chemotherapy and hormonal therapy has yet to be established. Adjuvant chemotherapy is recommended for patients with a Ki-67 index of >= 10\%, and hormonal treatment appears to be feasible in patients who are positive for estrogen and/or progesterone receptor.

    A case of elephantiasis nostras verrucosa treated successfully by a new type of compressive garment
    (WILEY, 2020-01-01) Mansur, A. Tulin; Ozker, Emre; Demirci, Gulsen Tukenmez
    Elephantiasis nostras verrucosa (ENV) is a clinical manifestation composed of hyperkeratotic, verrucous, and papillomatous lesions and dermal fibrosis, which complicate chronic lymphedema. There is currently no cure for ENV, however, several measures have been used to reduce lymphedema and the resultant pseudoepidermal hyperplasia. Supportive dressings and compression therapy still constitute an important part of the treatment. In this report, we present a 69-year-old male patient with ENV developed due to chronic lymphedema caused by venous insufficiency. After failure of healing with conventional two- and three-layered bandages, and elastic stockings, he was successfully treated by a new type of compression garment. We recommend this user friendly garment for prevention of frictional trauma, contact dermatitis, and secondary infection, which all may complicate compression treatments.

    Colorectal cancer is the third most common cancer in Turkey. The current guidelines do not provide sufficient information to cover all aspects of the management of rectal cancer. Although treatment has been standardized in terms of the basic principles of neoadjuvant, surgical, and adjuvant therapy, uncertainties in the management of rectal cancer may lead to significant differences in clinical practice. In order to clarify these uncertainties, a consensus program was constructed with the participation of the physicians from the Acibadem Mehmet Ali Aydinlar and Koc Universities. This program included the physicians from the departments of general surgery, gastroenterology, pathology, radiology, nuclear medicine, medical oncology, radiation oncology, and medical genetics. The gray zones in the management of rectal cancer were determined by reviewing the evidence-based data and current guidelines before the meeting. Topics to be discussed consisted of diagnosis, staging, surgical treatment for the primary disease, use of neoadjuvant and adjuvant treatment, management of recurrent disease, screening, follow-up, and genetic counseling. All those topics were discussed under supervision of a presenter and a chair with active participation of related physicians. The consensus text was structured by centralizing the decisions based on the existing data.
