Abstract
OBJECTIVE A large number of patients applying to the dermatology clinics are affected by fungal diseases, and a significant portion of which are superficial fungal infections. Dermatophyte infections are a notable public health concern and frequently encountered in clinical practice. Dermatophytosis not only compromises the quality of life but also predisposes individuals to various comorbidities due to its role as a gateway for secondary bacterial agents. This study aims to determine the species distribution of dermatophytes prevalent and assess their susceptibility to antifungal drugs. PATIENTS AND METHODS Skin, nail, and hair samples were obtained from patients with a clinical diagnosis of dermatophytosis. Samples were all cultured to isolate and identify the species. In vitro liquid microdilution tests were conducted to assess the susceptibility of the isolated strains against terbinafine, fluconazole, griseofulvin, and butenafine. RESULTS A total of 353 samples were obtained from the hair, skin, and nail lesions of 326 patients. Dermatophyte was isolated in 71 of the samples (20.1%). The cultured dermatophyte subtypes included Trichophyton rubrum (13.8% in 49 samples), Microsporum audouini (5.7% in 20 samples), and Trichophyton mentagrophytes (0.6% in 2 samples). Antifungal susceptibility testing revealed that terbinafine was the most effective antifungal drug against all dermatophyte species, while fluconazole exhibited the highest resistance. CONCLUSIONS The most common dermatophytosis agent in our region is T. rubrum. The least antifungal resistance was found against terbinafine. Conducting antifungal susceptibility tests is crucial for selecting effective treatment regimens and early detection of resistance development.

Abstract
Background and Aim The aim of this study was to evaluate radiographically the prevalence of mandibular nutrient canals (NCs) in patients with/without periodontal bone loss with aging and to correlate the number of NCs with the severity of bone loss using cone-beam-computed tomography (CBCT). Patients and Methods CBCT examinations of 208 patients were evaluated retrospectively of all patients, 114 had periodontal bone loss, whereas 94 patients were control subjects. Alveolar bone loss investigations were performed according to the Progressive Rate Index. Results NCs were observed in 55% of the control group and 86% of the periodontitis patients. NCs were more prevalent in the elderly age group with periodontal bone loss. In the study group, the NCs were statistically more frequent than in the control subjects (P > 0.05). Conclusion Statistical analysis showed a significant difference between the age groups and the prevalence of NCs increased in patients with periodontal alveolar bone loss with aging (P < 0.05).

Abstract
BACKGROUND Although the immune checkpoint inhibitors (ICIs) became a vital part of cancer care, many patients do not respond to treatment, indicating need for biomarkers. The Pan-Immune-Inflammation Value (PIV) is a recently developed peripheral blood count-based biomarker. Herein, we evaluated a PIV-based candidate scoring system as a prognostic biomarker in ICI-treated patients. METHODS A total of 120 advanced cancer patients treated with anti-PD-1 or anti-PD-L1 inhibitors for any cancer type were included in this study. The PILE scoring system incorporating the PIV (< median vs. ≥ median), lactate dehydrogenase levels (normal vs. > normal) and Eastern Cooperative Oncology Group performance status (0 vs. ≥ 1) was constructed from the multivariate analyses and used for stratification. The association between overall survival (OS), progression-free survival and PILE risk category was evaluated with multivariate analysis. RESULTS The median follow-up was 9.62 months and the median OS of all cohort were 12.42 ± 2.75 months. Patients with higher PIV had significantly decreased OS (7.75 ± 1.64 vs. 18.63 ± 4.26 months, p = 0.037). The patients in the PILE high-risk group (PILE score 2-3) had decreased OS (18.63 ± 4.02 vs. 5.09 ± 1.23 months, HR: 2.317, 95% CI: 1.450-3.700, p < 0.001) and PFS (7.69 ± 1.30 vs. 2.69 ± 0.65 months, HR: 1.931, 95% CI: 1.263-2.954, p = 0.002) compared to PILE low-risk group (PILE score 0-1). The Harrell C-Index values were 0.65 and 0.61 for OS and PFS prediction, respectively. CONCLUSION In this study, we demonstrated a decreased overall survival in ICI-treated patients with a higher PILE score. If prospective studies validate our results, PILE score could be a biomarker for immunotherapy.

Abstract
INTRODUCTION This study aimed to evaluate the relationship between tympanic plate morphology and degeneration of temporomandibular joint (TMJ) condyle and articular eminence (AE). MATERIAL AND METHODS Cone beam computed tomography images of 700 patients (345 males, 355 females) were evaluated. The prevalence and location of tympanic plate pneumatization (TPP) and foramen tympanicum (FT) were recorded. Sagittal scans of the TMJs were classified according to the degenerative bone changes of condyle and AE (flattening, osteophytes, erosion, sclerosis, and subcortical cysts). RESULTS TPP was found in 106 of 700 patients (15.2%) while FT was found in 165 (23.2%) of the patients. TPP and FT were bilateral in 52 (49.1%) patients and 46 (27.9%) patients, respectively. The mean axial diameter of FT was 2.53mm and the mean sagittal diameter was 2.52mm. The most common degenerative changes for condyle and AE were flattening. CONCLUSION To know these structures is important for surgical operations in the region of TMJ and ear to prevent complications. CBCT is useful to evaluate these anatomical landmarks and the relationship between them and the degenerative bone changes of condyle and AE.

Abstract
INTRODUCTION Kaposi sarcoma (KS) is an angioproliferative malignancy associated with HHV-8. It is mostly observed in patients affected by HIV and/or chronic immunosuppression, while classic KS without underlying immunosuppression are relatively rare. Systemic chemotherapy is used for advanced diseases, although there is no consensus in treatment algorithms. With the demonstration of PD-1 expression in KS, immune-checkpoint-inhibitors (ICI) emerged as possible treatment options. Notwithstanding, the data of ICIs is limited to case reports/series. Herein, we present a case of advanced classic KS, which has been treated successfully with nivolumab. CASE REPORT 82-year-old male patient was investigated for erythematous lesions on thigh. Punch biopsy lead to KS diagnosis. Abdominal CT showed lymphadenopathies in the inguinal region. After radiotherapy follow-up, patient had shown vertebral & gastric metastases. Because of the PSA elevation patient was diagnosed with prostatic adenocarcinoma. Metastases were investigated for origin. The lesions showed no uptake in Ga-68 PET-CT, therefore accepted as KS metastases. Patient rejected chemotherapy options and consented to immunotherapy trial.Management and outcome: Nivolumab was initiated 3 mg/kg bi-weekly with 12-dose protocol. After nivolumab patient wellbeing is improved and control endoscopy shown no metastases. With these findings patient has been assessed as complete response. DISCUSSION ICI on KS is still a blurred option to be included in standard regimens; but progressive understanding of PD-1 expression and its role in disease progression may be a milestone for further treatment algorithms on KS. Besides good efficacy, tolerability of ICIs could be helpful patients with comorbidities precluding the use of chemotherapy.

Abstract
INTRODUCTION Testicular germ cell tumors (GCT) are the most common tumor in young men. Their distinctive feature is the exceptional response to platin based combination chemotherapy.Since the prognosis is poor in relapsed and refractory patients, the immune checkpoint inhibitors are candidate agents in these patients although clinical trials are mostly lacking. Herein, we describe a patient with a refractory nonseminomatous GCT using nivolumab as a last resort therapy and provided long term response without any significant toxicity. CASE REPORT A 41-year-old male presented with the complaint of flank pain eleven years ago. The patient underwent a retroperitoneal lymph node excision and pathology reported as the mixed germ cell tumor. There were no mass in the testicles and the patient was diagnosed with a primary retroperitoneal GCT. Since the disease has progressed under multiple lines of chemotherapy and autologous stem cell transplantation, treatment was started with nivolumab. MANAGEMENT AND OUTCOME The patient started to treatment with nivolumab 3 mg/kg two weekly as a last resort treatment. The nivolumab was continued and the patient's response to this treatment is ongoing and has been stable for 13 months. DISCUSSION There are limited treatment options in platinum-refractory germ cell tumors. Recently, immune checkpoint inhibitors tried in this setting with some success in especially non-seminomatous GCTs. We see a good response and prolonged benefit with the use of nivolumab in our patient. Further research including prospective studies on the use of immune checkpoint inhibitors in platinum-resistant testicular cancer can further delineate the role of immunotherapy.

Abstract
PURPOSE In this study, we aimed to describe the real-life practice outcomes of pertuzumab-trastuzumab-taxane (PTT) combination in visceral organ metastatic, trastuzumab-naive breast cancer (BC) patients. METHODS This study was conducted by Turkish Oncology Group and included 317 patients' data from 36 centers. RESULTS Median age was 51 (22-82). Median PFS was 28.5 months, while median OS was 40.3 months. Patients with brain metastases (n: 13, 4.1%) had worse PFS (16.8 m vs. 28.5 m; p = 0.002) and OS (26.7 m vs. 40.3 m; p = 0.009). Patients older than 65 years of age (n: 42, 13.2%) had significantly lower OS results (19.8 m vs. 40.3 m; p = 0.01). Two hundred sixty-eight patients (86.7%) received docetaxel while 37 patients (11.7%) received paclitaxel. PFS and OS were similar between taxane groups. In eight patients (2.5%), 5-40% ejection fraction decrement from baseline was detected without any clinical sign of heart failure. CONCLUSIONS Our RLP trial included only visceral metastatic, trastuzumab-naïve BC patients including cases with brain involvement who received PTT combination in the first-line treatment. Regardless of negative prognostic characteristics, our results are in parallel with pivotal trial. Further strategies for brain metastasis should be developed to improve outcomes despite encouraging results with PTT treatment. Taxane selection can be personalized and endocrine maintenance may further improve outcomes after taxanes were discontinued. To our knowledge, this is the largest scale real-life clinical practice study of pertuzumab-trastuzumab-taxane therapy to date.

Abstract
BACKGROUND The aim of this study was to determine whether paranasal sinus dimensions and volume can be useful to identify gender and age estimation for ancient skulls using cone-beam computed tomography (CBCT) images. MATERIALS AND METHODS CBCT scans of 32 ancient skulls of approximately 1000 years of age were included in this retrospective study. The gender and age estimation of the skulls were made by an independent anthropologist, which was considered as the gold standard. Paranasal sinuses' dimensions (width and height) and volumes of each sinus were measured from the CBCT data set that was linked to the three-dimensional rendering software (Anatomage, Invivo 5.2). All measurements were performed by an independent observer. Intra-observer analysis was made. Mann-Whitney and Kruskal-Wallis tests were used to compare paranasal sinus parameters in terms of age estimation and gender (p < 0.05). RESULTS The results demonstrated no statistically significant difference between measurements (p < 0.05). The measurements were found to be highly reprodu- cible. The mean volumes of frontal and sphenoid sinus were found to be higher in males. The distance from anterior-posterior wall of sphenoid sinus in axial sec- tions is larger in males (p > 0.05). The frontal sinus width and volume increased statistically with age above 60 years of age (p > 0.05). CONCLUSIONS The paranasal volume and dimensions' measurements from CBCT data can be a promising technique to determine gender and age of ancient skulls because of its lower voxel sizes and higher resolution.

Abstract
Introduction The present study indicates that simple and hydatid cysts in liver are a common health problem in Turkey. The aim of the study is to differentiate different types of hydatid cysts from simple cysts by using diffusion-weighted images. Materials and Methods In total, 37 hydatid cysts and 36 simple cysts in the liver were diagnosed. We retrospectively reviewed the medical records of the patients who had both ultrasonography and magnetic resonance imaging. We measured apparent diffusion coefficient (ADC) values of all the cysts and then compared the findings. Results There was no statistically meaningful difference between the ADC values of simple cysts and type 1 hydatid cysts. However, for the other types of hydatid cysts, it is possible to differentiate hydatid cysts from simple cysts using the ADC values. Conclusion Although in our study we cannot differentiate between type I hydatid cysts and simple cysts in the liver, diffusion-weighted images are very useful to differentiate different types of hydatid cysts from simple cysts using the ADC values.

Abstract
AIM Apical extrusion of debris in primary root canal treatment has not been well elucidated. The purpose of this study is to compare the amount of apically extruded debris during the preparation of primary molar root canals using ProTaper, ProTaper Next, Self-adjusting File (SAF) and hand files. MATERIALS AND METHODS One hundred sixty extracted primary mandibular molar teeth were assigned to 2 groups: Group 1: Resorbed (n=80) and Group 2: Non-resorbed (n=80) and randomly to four subgroups (n=20 teeth for each subgroup) according to the instruments used, ProTaper, ProTaper Next, SAF, and hand file. The apically extruded debris was collected and dried in preweighed Eppendof tubes. The dry weight was calculated by subtracting the preoperative weight from the postoperative weight. STATISTICS Data were analysed statistically using the ANOVA and the Bonferroni post hoc t-test. RESULTS The amount of apically extruded debris was significantly less for the non-resorbed group compared to the resorbed group (P<0.05). Regardless of the resorption groups, ProTaper Next and SAF extruded significantly less debris than did the ProTaper and hand files (P<0.05), while no statistically significant difference was found between ProTaper Next and SAF (P>0.05). CONCLUSION All instruments caused apically extruded debris in primary teeth.

Abstract
Polymethyl methacrylate is the most commonly used contact lens material due to its excellent optical properties. However the presence of residual monomer in the structure alters its transparency as well as its biocompatibility, thus, there is a need to detect any remaining methyl methacrylate. Raman spectroscopy is a rapid, sensitive, and non destructive method as compared to other spectroscopic, chromatographic or polarographic methods. In this study, the spectra of some lens materials (prepared from methyl methacrylate, 2-hydroxy ethyl methacrylate, hexamethyl disiloxane and polypropylene glycol with or without the addition of crosslinker ethylene glycol dimethylacrylate) were obtained by Raman spectroscopy. It was observed that an amount of crosslinker present in the structure proves effective for the unpolymerized monomer content. None of the samples, except those containing hexamethyl disiloxane, demonstrated any monomer residue.

Abstract
Purpose To investigate whether the central corneal thickness (CCT) shows alterations in Graves disease and Graves ophthalmopathy (GO) cases according to the disease severity and hormonal status of the patients. Methods A total of 150 patients (62 male, 88 female) with Graves disease and 32 control subjects (11 male, 21 female) were included in the study. The patients were divided into six groups according to the severity of orbital involvement and thyroid hormone status. Best-corrected visual acuity, pupillary responses, color vision, biomicroscopy, CCT, intraocular pressure, and funduscopy were performed, and proptosis was measured with Hertel exophthalmometry in all patients. Results CCT values of patients with Graves disease and patients with GO with hyperthyroid or euthyroid hormonal status showed no statistical difference among themselves and versus control subjects (p>0.05). Conclusions Hyperthyroidism or severity of orbital disease does not affect the CCT.

Abstract
INTRODUCTION Chronic otitis media (COM), affecting all over the world and in a wide range of age groups in Turkey, is an important cause of ear discharge and hearing loss. The main clinical manifestations are tympanic membrane perforation, ear, nose and throat problems. On the tympanic membrane perforation becomes persistent and cholesteatoma development, there are a lot of opinions today. Especially in the pathology associated with otitis media with effusion eustachian tube, it is known that COM and cholesteatoma develop. MATERIALS AND METHODS In our study, we interpreted 210 patients' temporal computed tomography (CT). Seventy of these 210 patients had otitis media with cholesteatoma, 70 patients had only otitis media without cholesteatoma, and 70 patients had no otitis media. The eustachian tubes were evaluated using temporal CT multiplanar reconstruction method. Angles with the horizontal plane of the eustachian tube and Reid and tubotympanic angles were measured. RESULTS The angles between eustachian tube and horizontally oriented Reid plane of the patients with cholesteatoma were found to be significantly lower than the patients with otitis media without cholesteatoma and the patients with no history of otitis media. For the tubotympanic angle, no statistically significant differences were observed between the groups. CONCLUSION These results suggest that the decrease in the angle with the horizontal plane of Reid in the eustachian tube in adults may play a significant role in the etiology of cholesteatoma.

Abstract
BACKGROUND Synovial sarcoma (SS) is a malignant mesenchymal tumor, which comprises 5%-10% of all the sarcomas. There is insufficient information on prognostic factors and salvage treatments of advanced SS. In this study, we aimed to further clarify the clinicopathological features, prognostic factors, and treatment modalities in advanced SS. MATERIALS AND METHODS A total of 45 SS patients followed up between 2001 and 2015 at our cancer institute, Department of Medical Oncology, were retrospectively evaluated. Eleven patients were initially metastatic, and remaining patients developed metastasis or became inoperable due to locally advanced disease. Overall survival was evaluated by Kaplan-Meier analysis. RESULTS The median age of patients was 37 (17-70) years and 60% (n = 26) of them were female. SS was most commonly localized in the lower extremity and abdomen-pelvis (29% and 29%, respectively). Median follow-up time was 33 (6-175) months. Patients were treated with a median of two (1-5) line chemotherapies at metastatic stage. Ifosfamide plus adriamycin (IMA) (49%, n = 22) and cisplatin-etoposide (13%, n = 6) were the most often used chemotherapy regimen as first line in metastatic stage. Partial response was obtained in 32% of the patients treated with IMA chemotherapy. Furthermore, median progression-free survival was 6 (1-123) months. Median survival of metastatic stage at diagnosis or in follow-up was 21 months (14-27) and 21 (12-29) months (P = 0.53), respectively. Most metastatic locations were lung (75%) and bone. Factors influencing survival at metastatic stage were evaluated; statistically significant longer survival was observed in patients with lung metastasis, primary tumor size smaller than 10 cm, patients who underwent surgery for the metastasis, and development-to-metastasis period longer than 12 months. CONCLUSION Median survival of patients in metastatic stage SS was 21 months. Lung was the most common metastatic site.

Abstract
INTRODUCTION Shear wave elastography is a method for the measurement of tissue stiffness. The advantage of this method is that its outcome is not operator dependent. Our aim was to compare the elastiscity values of the right lobe of the liver of normal weighted and morbidly obese patients. MATERIALS AND METHODS The mean elastiscity values of the right lobe of the liver were calculated for 38 normal weighted and 37 morbidly obese patients. All the patients had no history of liver disease. RESULTS The mean elastiscity value was significantly higher in morbidly obese patients than (25,7 +3,30 kPascal) in normal weighted patients for the right lobe of liver (10,55 +2,20 kPascal). CONCLUSION Morbidly obese patients have a potential risk for liver fibrosis even in the absence of hepatosteatosis.
