Aim: To compare the vascular densities (VDs) of macular microvascular (MMV) and radial peripapillary
capillaries (RPC) according to Erectile dysfunction (ED) in non-ocular Behçet's (NOB) patients, and to
examine the correlation between the patients' International Index of Erectile Function (IIEF)-15 scores in 5
different sexual function domains and the values measured by OCT -A.
Patients and Method: This cross-sectional study was conducted between April 2019 - March 2020. Of the
94 male Behçet's patients, 23 without eye involvement and who met the inclusion criteria were included in
the study. The control group consisted of 25 age-matched healthy individuals. Values measured by optical
coherence tomography angiography (OCT-A) were compared between patients with and without ED and
controls. The correlation between the patients' scores in 5 different sexual function domains of the IIEF-15
questionnaire and those measured by OCT -A was examined.
Results: Compared to controls, VDs were reduced in the whole area of the deep capillary plexus in both
patients with and without ED. VDs of all vessels of the whole area in the RPC network were also decreased
in EDs compared to controls and non-EDs. In addition, retinal nerve fiber layer (RNFL) thicknesses in the
inferior quadrant were found to be decreased in patients with ED compared to controls and those without ED.
In the correlation analysis between NOB patients' scores in 5 domains of IIEF-15 and OCT-A measurements,
there was a positive correlation between the RNFL thickness values and VDs of all vessels in the whole area
of RPC, and the scores in 4 domains of IIEF-15.
Conclusions: After excluding factors that may cause ED, MMV and RPC VDs and RNFL inferior quadrant
thicknesses were found to be decreased in NOB patients with ED. In addition, a correlation was found between
IIEF-15 scores in sexual function domains and RPC VDs and RNFL thicknesses of NOB patients.

We have studied on 47 thyroidectomy material that vvere came to Fırat University Medical Faculty Department of Pathology for the determination of proliferative activity. PCNA method vvere applied, normal thyroid(9), adenomatous goiterfl 1), follicular adenoma(7), papillary carcinoma(l6), follicular carcinoma(2) and anaplastic carcinoma(2). Ali cases paraffin sections stained PCNA/cydin monoclonal antibody. Positive painted nuclei vvas evaluated and PCNA indices vvere calculated as percentage. PCNA indices vvere evaluated normal thyroid %0.5, adenomatous goiter %2.1, follicular adenoma %2.6, papillary carcinoma %6.2, follicular carcinoma %15.7 and anaplastic carcinoma %32.2. As a conclution, thyroid carcinomas shovved significantly increased numbers of PCNA positive cells when compared vvith benign thyroid tumors.

Objective: Most of the renal neoplasms are the epithelial and malign ones. The renal cell carcinoma (RCC), which is the most frequently seen malign renal tumor, consists of 2-4% of all the malign tumors seen among adult individuals and 80-90% of all the malign renal tumors. RCCs peak at sixties and seventies and its prevalence among males is two folds of its prevalence among females. RCCs have bad prognosis. The recurrence is seen in 40% of the cases, and the metastasis despite the early diagnosis was detected in 50% of cases. In present study, it was aimed to distribution of renal tumors in our hospital, discuss the prognostic factors such as the, pathological stage, nuclear grade and tumor diameter accompanied by literature information.

Patients and Method: By retrospectively scanning the records of Pathology Department of Medical Faculty, Fırat University, for the period between 1988 and 2009, 140 renal tumor cases were determined and the previous diagnoses, histological degrees, pathological stages of these cases were evaluated and the final diagnoses were taken as base in the present study. In pathologically staging (pT) of RCCs, TNM classification was used, whereas Fuhrman nuclear grading (FNG) was used in nuclear grading procedure. The patients were divided into different groups based on their genders and ages. The statistical analyses were performed in SPSS-12.0 software by using Chi-Square and Correlation tests.

Results: When compared to the literature in terms of the mean age, the present study involves relatively young population (mean age 57), and the majority was male (male/ female:1.1). The distributions of renal tumours, malign and benign subtypes, and RCC subtypes show similarities with the general literature. When examining the RCCs statistically, no significant relationship was found between diagnosis and age, and between nuclear grade and tumor diameter (p>0.05). In the present study, the RCCs with largest diameter were papillary type (9,78cm) ones, whereas the RCCs with lowest diameter values were classic type. A statistically significant relationship was observed between the benign, borderline and malign tumor diagnoses and diameters (p= 0.023). It was determined that approximately one-four of RCC cases were in highly pathological stage (21,6%, pT3a-3b). A direct proportional and statistically significant relationship was found between nuclear grade and diameter (p=0,002).

Conclusion: RCCs have poor prognosis and their frequency is increasing. Pathological stage, nuclear grade and diameter are the leading factors affecting the prognosis. As in our study, in retrospective studies involving old ages and not enough sampling, tumor diameter may be used as an alternative prognostic factor for pathological staging in tumors with a stage above pT2.

Introduction: Our aim is to evaluate the cardiac involvement of Neurofibromatosis type 1  patients in our region and to compare them with other clinical findings. In this study, we wanted to show the frequency and variety of cardiac involvement.

Material and Methods: Patients diagnosed with Neurofibromatosis type 1  in Hatay Mustafa Kemal University Medical Faculty Pediatric Neurology Clinic between 01/09/2019 and 01/09/2020 were included in the study. The patients included in the study were examined by a Pediatric Cardiology Specialist, and echocardiography and electrocardiography were taken. Demographic information, examination findings, brain magnetic resonance images were collected from the files of the patients. Electrocardiography and echocardiography were examined and recorded by the Pediatric Cardiology Specialist.

Results: We accepted 17 patients from our center to the study. Six patients (35.3%) were diagnosed with sporadic Neurofibromatosis type 1, while 11 patients (64.7%) had familial Neurofibromatosis type 1. All of our patients had cafe au late spots on the skin. In addition, 10 (58.8%) patients also had axillary and / or inguinal freckles. We detected optic glioma in 3 of our patients with ocular involvement, and lish nodules in 3 of them with papillary edema. When we looked at central nervous system involvement, we encountered various involvements in brain MRIs of 8 (47%) patients. In our cardiac examination, we found QT length in 1 patient’s electrocardiography. In the echocardiography we performed for the detection of cardiac structural pathologies, we detected nodular appearance compatible with subendocardial neurofibroma in 3 patients, mitral insufficiency in 3 patients, patent foramen ovale in 1 patient, atrial septal defect in 1 patient, and bicuspid aorta in 1 patient.

Discussion: In our study, unlike the literature, subendocardial nodular hyperechogenic appearance was present in 3 patients. Although these findings are quite rare, subendocardial nodular hyperechogenic images in 3 of our 17 patients suggest that this pathology may be more common. In addition, one of our patients had a long QT. As far as we know, this is the first case of Neurofibromatosis type 1 and Long QT syndrome. In conclussion; Cardiac involvement in patients with Neurofibromatosis type 1 could more common than mentioned in the literature.

Papillary cystic neoplasrn of the pancreas is a rare pancreatic condition with low grade malignant behavior. It occurs mainly in young adult females and surgical resection is amenable to cure in early cases. A 26 yaar old woman who had epigastric mass and pain was operated on with the diagnosis of pancreatic tumor and biopsy specimens showed papillary cystic tumor. We report this case for it is a rare condition. great in size and his-tologically documented vascular and capsular invasion with no metastases.

We aimed to propose a management in a patient with thyroidectomized and high thyroglobulin (Tg) level, but negative radioiodine scan, whose lymph nodes detected with PET/CT. PET/CT was done to a patient, 31 years-old, with thyroidectomized and given radioiodine treatment, but not followed for a long time, for high Tg level and negative radioiodine scan. Metabolically active lymph nodes were detected in the cervical region. So, lymph nodes were excised with minimally invasive surgery. Radioiodine treatment was done because of papillary carcinoma metastasis. PET/CT may contribute to diagnosis in cases of high Tg levels, but negative radioiodine treatment in differentiated thyroid carcinoma.

Black hairy tongue, also named as lingua villosa nigra, is a painless, asymptomatic, benign condition characterized by an abnormal brownish–black discoloration of the dorsal surface of the tongue caused by variety of precipitating factors. It usually appears in people over age 40 years with a history of poor oral hygiene, smoking and antibiotic use. Here we report a case of 65-year-old diabetic woman patient presented to our outpatient clinic with black hairy tongue. By means of this case, data about this disorder will be able to reviewed and reminded to be aware of this rarely seen disease in daily practice and advise to pay more attention to oral hygiene and brushing techniques that will help treating this disorder.

In this light microscopic study, the effects of age and sex on the thickness of epidermis and the number of melanocytes were determined in human skin samples by using histological methods. Skin samples from a group of various ages including 10 men and 10 women were fixed in 10 % formaldehyde solution.The formalin fixed skin samples were processed using routine histologic procedures and embedded in paraffin. In this study, the most consistent results are in the epidermis of aging individuals is flattenning of the dermo-epidermal junction and decreased number of dermal papilla. However, it was found that numbers of melanocytes in epidermis decreased with age and changed with sex. Consequently, there is a significant statistical difference between epidermis thickness and age ( p< 0,0001 ). However, a high negative correlation was determined between epidermis thickness and age ( r= -0,8047). In conclusion epidermal thickness decrease %80 with age. But there is a no significant statistical difference between epidermis thickness and sex ( p= 0,7622). Also, there is a significant ( p

Abstract

Aim: We aimed to assess the changes in retinal nerve fiber layer (RNFL) and optic nerve head (ONH) in patients with chronic obstructive pulmonary disease (COPD).

Patients and Methods: Thirty patients having severe COPD and 29 age and sex-matched healthy subjects were enrolled in the study. After a detailed ophthalmic examination, the ONH and RNFL thickness measurements were taken by an optical coherence tomography (OCT) (Stratus OCT-3). Arterial blood gases (pO₂ and PCO₂) were measured and respiratory functional tests were performed for the staging of COPD patients. The OCT parameters were compared difference between the 2 groups using independent t test, while Pearson correlation analysis was performed to assess the correlations between respiratory functional tests, arterial blood gases and RNFL thickness parameters. A p value less than 0.05 was accepted as statistically significant.

Results: There were no significant differences in optic disc area, cup area and rim area between COPD and healthy subjects (p>0.05). Parameters of mean and superior quadrant RNFL thickness were found to be significantly thicker in COPD subjects (114.52±7.7 µm and 141.07 ±18.2 µm, respectively) compared to the control subjects (107.9±5.4 µm and 131.31±13.6 µm, respectively) (p<0.05). No correlation was found between pO₂ and RNFL thickness (r=-0.22, p=0.33). There was a moderate correlation between pCO₂ and superior quadrant RNFL (r= 0.53 and p=0.017), and a high negative correlation between FEV₁/FVC and superior quadrant RNFL (r=-0.76, p=0.003).

Conclusions: The increase in pCO2 and the decrease in FEV1 / FVC indicate increased hypoxia. Peripapillary RNFL loss associated with RGC death can be masked by hypoxia / ischemia-induced retinal and optic disc edema. Increased mean RNFL thickness in COPD patients was thought to be due to retinal edema associated with increased hypoxia.
