Abstract
OBJECTIVE Renal biopsy contributes to the diagnosis, follow-up, and treatment of many rheumatic conditions. This study assessed the diagnostic role and safety of renal biopsies in a tertiary rheumatology clinic. METHODS Renal biopsies performed between June 2020 and December 2022 were screened, and demographic, clinical, histopathological, and safety data were collected from patient records. RESULTS In this study, 33 males and 38 females were included. Except for 1 patient who received acetylsalicylic acid, antiaggregant, and/or anticoagulant drugs were stopped before the biopsy. Complications included a decrease of hemoglobin in 8 patients (11.3%) and microscopic hematuria in 40 patients (56.3%). Control ultrasonography was performed in 16 patients (22.5%), and a self-limiting hematoma was found in 4 of them (5.6%) without additional complications. While less than 10 glomeruli were obtained in 9 patients (9.9%), diagnosis success was 94.4%. Histopathological data were consistent with one of the pre-biopsy diagnoses in 54 of 67 cases (80.6%) but showed discrepancies in 19.4% (n=13) of patients. A repeat biopsy was performed in 7 patients for re-staging or insufficient biopsy. CONCLUSIONS Renal biopsy significantly contributes to rheumatology practice, especially in patients with complex clinical and laboratory findings or in whom different treatments can be given according to the presence, severity, and type of renal involvement. Although the possibility of obtaining insufficient tissue and the need for re-staging and repeat biopsy in the follow-up might be expected, complication risk does not seem to be a big concern. Renal biopsy often evidenced discrepancies between pre-biopsy diagnosis and histopathological findings.

Abstract
Cytotoxic activity-guided isolation studies on the underground parts of Valeriana sisymbriifolia Vahl. led to the isolation of 12 secondary metabolites including two undescribed iridoids, sisymbriifolivaltrate and sisymbriifolioside, and two unreported sesquiterpene lactones, sisymbriifolins A and B. Chemical structures of the isolates were established by extensive 1D and 2D NMR analyses as well as HR-ESI-MS. The in vitro cytotoxic activities of the extract, sub-fractions and isolates on lung (A549), breast (MCF7), gastric (HGC27) and prostate (PC3) cancer cell lines were evaluated by MTS assay. Sisymbriifolivaltrate, didrovaltrate, valtrate, 7-homovaltrate and 1-α-acevaltrate exhibited promising cytotoxic activity on MCF7 cell line with IC50 values ranging from 2.5 to 12.3 μM, while valtrate demonstrated the best cytotoxicity against A549 cells with the IC50 value of 7.5 μM. Valtrate and 7-homovaltrate were found to exert noteworthy cytotoxicity towards HGC27 cell line (IC50 values: 2.3 and 3.7 μM, respectively), whereas valtrate, 7-homovaltrate and 1-α-acevaltrate (IC50 values: 2.3-9.7 μM) were found to be potent cytotoxic against PC3 cells. Among the tested compounds, particularly valepotriate-type iridoids were found to be the main cytotoxic principles of V. sisymbriifolia.

Abstract
Thrombotic and microangiopathic effects have been reported in COVID-19 patients. This study examined the contribution of the hereditary thrombophilia factors Prothrombin (FII) and Factor V Leiden (FVL) genotypes to the severity of COVID-19 disease and the development of thrombosis. This study investigated FII and FVL alleles in a cohort of 9508 patients (2606 male and 6902 female) with thrombophilia. It was observed that 930 of these patients had been infected by SARS-CoV-2 causing COVID-19. The demographic characteristics of the patients and their COVID-19 medical history were recorded. Detailed clinical manifestations were analyzed in a group of cases (n = 4092). This subgroup was age and gender-matched. FII and FVL frequency data of healthy populations without thrombophilia risk were obtained from Bursa Uludag University Medical Genetic Department's Exome Databank. The ratio of males (31.08%; 27.01%) and the mean age (36.85 ± 15.20; 33.89 ± 14.14) were higher among COVID-19 patients compared to non-COVID-19 patients. The prevalence of FVL and computerized tomography (CT) positivity in COVID-19 patients was statistically significant in the thrombotic subgroup (p < 0.05). FVL prevalence, CT positivity rate, history of thrombosis, and pulmonary thromboembolism complication were found to be higher in deceased COVID-19 patients (p < 0.05). Disease severity was mainly affected by FVL and not related to genotypes at the Prothrombin mutations. Overall, disease severity and development of thrombosis in COVID-19 are mainly affected by the variation within the FVL gene. Possible FVL mutation should be investigated in COVID-19 patients and appropriate treatment should be started earlier in FVL-positive patients.

Abstract
Abstract
Background
The aim of this study is to determine the effect of ACE gene polymorphism on the parameters studied (push-up & sit-up) in a long-term study, which has been carried out for many years and to find out whether the differences in ACE gene's metabolism due to the influence of parameters such as outside impacts and lifestyle (active or sedentary life) have a role in the development of strength endurance or not.
Main text
59 male army officers made up the research team. A follow-up study of strength endurance (push-up and sit-up) test was conducted in the gym. The exam took two minutes to complete, and each application was tested separately. In both 2004 and 2019, persons with genotype ID had the best mean sit-up and push-up outcomes, followed by participants with genotype DD, and finally participants with genotype II (P 0.05). Compared to the original rates in 2004, all genotype groups showed a significant reduction in push-up and sit-up scores in the test.
Conclusion
The findings of this study may reveal if strength and lifestyle choices affect the metabolic implications of the genetic polymorphism in the body. Particular varieties actuated by genes, on either hand, don’t result in significant improvements without any changes in individuals’ practices or ways of living, as per the conclusions.

Abstract
Relapsing polychondritis (RP) is a a rare multisystemic disease and it affects cartilaginous tissue and proteoglycan rich organs. The spectrum of clinical features are intermittent inflammation involving especially the auricular and nasal regions. In some patients with RP, systemic vasculitis, autoimmune diseases or malignancy may accompany. Although rare, any of the ANCA-associated vasculitis have been reported in patients with RP. Eosinophilic granulomatous with polyangiitis (EGPA) is a multisystem small vessel vasculitis associated with asthma and eosinophilia. Here we present a case of coexistence of RP and EGPA.

Abstract
BACKGROUND Congenital myasthenic syndromes (CMS) are composed of numerous hereditary disorders involving genetic mutations in proteins essential to the integrity of neuromuscular transmission. The symptoms of CMS vary according to the age at onset of symptoms, and the type and severity of muscle weakness. Effective treatment and genetic counseling depend upon the underlying pathogenic molecular mechanism and subtype of CMS. METHODS A retrospective and cross-sectional study was performed with 16 patients with a genetically confirmed diagnosis of CMS to share our experience with clinical symptoms, demographic data, genetic variants, and treatments applied. RESULTS Sixteen patients with a specific CMS genetic diagnosis (three novel mutations) were identified, including CHRNE (n = 7), DOK7 (n = 2), AGRN (n = 2), RAPSN (n = 1), CHRNA1 (n = 1), CHRNB1 (n = 1), CHAT (n = 1), and SCN4A (n = 1). Age at onset of symptoms ranged from the neonatal period to 12 years. Genetic diagnosis was confirmed between the ages of three months and 17 years. A significant delay was determined between the onset of symptoms and genetic diagnosis of the disease. CONCLUSIONS This study highlights the importance of genetic testing in CMS. Due to the rarity of CMS, more cases will be recognized and reported as the use of laboratory and genetic testing accelerates. We hope that our experience will grow and contribute further to the literature as clinical follow-up and treatment increase.

Abstract
The lactate/albumin (L/A) ratio correlates with Acute Physiology and Chronic Health Evaluation 2 (APACHE-2) and Sequential Organ Failure Assessment (SOFA) scores. This study examined whether the L/A ratio has prognostic value in a larger group of critically ill (adult) patients admitted to an intensive care unit (ICU) due to pneumosepsis.This retrospective study analyzed the data of 273 patients with pneumosepsis admitted to the Internal Medicine ICU of Adana City Training and Research Hospital between 2018 and 2020. Patients diagnosed with pneumosepsis were included in the study. The data were obtained from the hospital system. Patients who had cancer, who were pregnant, and patients whose necessary data could not obtain for the study were excluded from the study.The L/A ratio was superior to lactate or albumin alone as a predictor of mortality. Furthermore, this result was valid for patients with kidney and hepatic dysfunction. A correlation occurred between the L/A ratio and APACHE-2 and SOFA scores in patients with pneumosepsis.The L/A ratio can be an independent predictor of mortality in patients with pneumosepsis and patients with pneumosepsis with renal and hepatic dysfunction. The L/A ratio correlated positively with lactate levels and APACHE-2 and SOFA scores but negatively with albumin levels.

Abstract
BACKGROUND Cystic fibrosis, a pulmonary disease which is an autosomal recessive, inherited, multisystemic genetic disease commonly seen in the Caucasian race, is the most frequent cause of mortality and morbidity. So far, more than 2000 disease-causing gene variants have been found and this number has been increasing with the studies conducted. Although there is not yet enough data that include the Turkish population, the recent increase of studies is noteworthy. AIMS To discover the genetic variation in patients diagnosed with cystic fibrosis in the Central Anatolian region. STUDY DESIGN Cross-sectional study. METHODS The study was carried out in the Central Anatolian region in 3 pediatric pulmonology departments (Kayseri, Konya, and Ankara) in Turkey between July 2014 and December 2017. The Sanger and Next Generation Sequence analyses were used for exon and exon-intron boundaries in the cystic fibrosis transmembrane conductance regulatory (CFTR) gene, and in selected patients, mutation analysis was performed using the Multiplex Ligation-dependent Probe Amplification technique for large deletions and duplications. RESULTS CFTR gene analysis was performed for 316 patients and 215 of them were genetically diagnosed with cystic fibrosis. Sixtythree different variants were defined in these patients and 7 of these were large deletions/duplications detected with the MLPA method. The most frequent variants were F508del (29.6%), G85E (8.2%), N1303K (8.2%), Y515* (7.5%), and G542* (3.4%). CONCLUSION Using sequencing and Multiplex Ligation-dependent Probe Amplification methods, the identification of seven new mutations that were not previously reported in the literature contributes to a better understanding of the heterogeneous nature of CFTR mutations in the Turkish population. When no mutations are detected (pathogenic/probably pathogenic) in clinically compatible cases, Multiplex Ligationdependent Probe Amplification analysis contributes significantly to the diagnosis.

Abstract
Objective There are currently no studies on the role of vitamin D receptor (VDR) levels
as a cause of or risk factor for sepsis. We aimed to establish the
association between VDR levels and 28-day mortality in critically ill
patients with sepsis. Methods This prospective cross-sectional observational study included 148 patients
diagnosed with sepsis who were treated in the intensive care unit. We
measured VDR levels, laboratory characteristics, and health scores and
related them to survival. Results The 148 patients included 96 survivors and 52 non-survivors, with VDR levels
of 1.92 and 1.36 ng/mL, respectively. Baseline VDR was a significant
predictor of 28-day mortality, with an area under the curve of 0.778. A low
VDR level was significantly associated with lower overall survival in
patients with sepsis according to Kaplan–Meier curve analysis. VDR levels
were also negatively correlated with lactate, C-reactive protein, acute
physiological and clinical health evaluation (APACHE) II and sequential
organ failure assessment (SOFA) scores, and disease severity. Conclusions VDR levels were associated with high 28-day mortality and negatively
correlated with lactate, C-reactive protein, APACHE II and SOFA scores, and
disease severity in patients with sepsis. VDR levels can predict poor
outcomes in patients with sepsis.

Abstract
Background Iodine uptake is a main factor affecting thyroid disease. In Turkey, mandatory salt iodization began in 1999-2000. Aims This study in 2009 determined the prevalence of thyroid diseases in older people in Mamak district, Ankara after iodization to ascertain if salt iodization alone is sufficient to reach adequate iodine levels in the older population. Methods All Mamak residents ≥ 65 years were eligible for inclusion in the study. Demographic data and medical history were recorded. All participants had a thyroid ultrasound. Blood samples were taken to assess thyroid function and autoantibodies, and urine samples to assess iodine concentration. Participants with low levels of thyroid stimulating hormone underwent scintigraphy to assess thyroid uptake. Fine-needle aspiration biopsy was done of nodules ≥ 1.5 cm where thyroid stimulating hormone was not suppressed. Results Of 1200 eligible residents, 979 were included. Their mean age was 70.9 (standard deviation (SD) 5.7) years; 49.7% were women. Mean urinary iodine concentration was 98 (SD 81.29) μg/L. Goitre was found in 18.2% (89/487) of women and 6.7% (33/492) of men (P < 0.001) and 43.8% (428/979) had nodules. Subclinical hypothyroidism was found in 5.8% (57/979) of the participants, overt hyperthyroidism in 0.8% (8/979), subclinical hyperthyroidism in 2.2% (22/979) and T3 thyrotoxicosis in 0.3% (3/979). Toxic multinodular goitre and toxic adenoma caused 80% of hyperthyroidism cases. Biopsy detected no malignant pathology. Conclusion After salt iodization, iodine levels have not yet reached favourable levels in older people. Iodization of salt seems insufficient to achieve these levels in older people; alternative iodine supplementation should be considered.

Abstract
BACKGROUND The sex hormone estrogen has an immune-supporting role in both trauma and sepsis-related to its immune-modulator role. The aim of the current study was to examine the prognostic role of (serum G Protein-coupled estrogen receptor-1) GPER-1 in sepsis and sepsis-related mortality. METHODS Prospective evaluation was made of the data on a total 160 patients followed-up in the Intensive Care Unit because of sepsis. Patients were separated into two groups as survivor and non-survivor group. The Sequential Organ Failure Assessment (SOFA) Score, APACHE II Score and Charlson Comorbidity Index (CCI) were calculated for each patient. Serum GPER-1 levels were evaluated for each patient. RESULTS Compared with non-survivors, the surviving patients were determined with significantly higher levels of PLT, CRP, GPER-1, SOFA, and APACHE II scores. The GPER-1 levels showed a significant positive correlation with CRP levels, SOFA, and APACHE II scores. ROC curve analysis demonstrated 85.7% sensitivity and 72.1% specificity of GPER-1 to predict 28-day mortality. GPER-1 and APACHE II scores were determined to be an independent prognostic factor for predicting mortality. CONCLUSIONS Serum GPER-1 can be used as a new prognostic factor for survival in patients diagnosed with sepsis.

Abstract
ABSTRACT The mortality rate of patients diagnosed with sepsis is high. To date, many markers in sepsis patients have been studied to diagnose, determine their prognosis, and contribute to treatment. These studies were conducted in both experimental and clinical settings, but clinical trials remain limited. Therefore, more well-planned clinical studies are needed in patients with sepsis.The current study aimed to examine the prognostic role of signal peptide-CUB-epidermal growth factor-like domain-containing protein 1 (SCUBE-1) in sepsis and sepsis-related mortality. We also wanted to study its relationship with inflammatory markers and scoring systems.This prospective, cross-sectional, observational study included a total of 187 sepsis cases treated in the intensive care unit. Venous samples were obtained after diagnosis. The patients were separated into 2 groups: (1) the survivor group who were discharged or transferred within 28 days of the first diagnosis and (2) the nonsurvivor group who died within 28 days of the first diagnosis.The SCUBE-1, C-reactive protein, procalcitonin, creatinine, lactate values, acute physiology and chronic health evaluation 2, sequential organ failure assessment scores were significantly higher in the survivor group, and platelets were higher in the survivor group. In addition, SCUBE-1 positively correlated with the inflammatory markers C-reactive protein, lactate, sequential organ failure assessment, and acute physiology and chronic health evaluation 2. Additionally, the SCUBE-1 value predicts 28-day mortality, and the optimal cutoff value for predicting mortality is 4,73 pg/mL.Sepsis is a disease with high mortality. SCUBE-1 can be used as a new prognostic factor for sepsis patients.

Abstract
Cystic fibrosis (CF) is one of the most common autosomal recessive and multisystemic diseases. CF affects many systems. One of these systems is the endocrine and exocrine functions of the pancreas, causing cystic fibrosis-related diabetes, which is extremely complex and has unique pathogenesis. Maturity-onset diabetes of the young (MODY) is a rare type of diabetes with autosomal dominant inheritance and is not expected in patients with CF. In this study, we present MODY due to a novel glucokinase gene mutation, which is an unexpected form of diabetes in patients with CF. This is previously unreported in the literature.

Abstract
Background Cystic fibrosis is the most common metabolic chronic disease among European Caucasian children. Cystic fibrosis incidence in Northern Europeans countries is approximately 1 in 3000 births while the worldwide prevalence varies considerably. Aims To determine the incidence of cystic fibrosis in the central region of Anatolia in Turkey using the newborn screening program data. Study Design Cross-sectional study Methods We used the records of the newborn screening program which is implemented by the Konya and Kayseri Provincial Health Directories. Between January 2015 and December 2016, there were a total of 119006 live births in Konya and Kayseri. The newborn screening test was applied to all these babies. Results During this period, there were 22 live born babies diagnosed with cystic fibrosis in Konya with an incidence of 2.9 per 10000 live births and 13 live born babies diagnosed with cystic fibrosis in Kayseri with an incidence of 2.8 per 10000 live births. In genetic of 30 patients, fifteen patients were homozygous, and 15 patients were a compound heterozygote. Twenty-one different gene variants were detected and the most common mutation was F508del (17/30). Conclusion We found the incidence of cystic fibrosis in central Anatolia similar to northern European countries.

Abstract
Objective: Hyperferritinemia cataract syndrome (HFCS) is an autosomal dominantly inherited disease characterized by increased serum ferritin levels and bilateral cataract formation in the early period of life. Heterozygote mutations in the 5’ untranslated region of the L-ferritin gene (FTL) have been reported to cause this disease. In this study, our purpose was to research the FTL gene mutations that cause HFCS in Central Anatolia and the clinical effects of these mutations. Materials and Methods: Seventeen patients from 6 families with high ferritin levels in performed serum measurements, those who were found to have cataracts in eye examinations, and families with vertical inheritance, since the disease is autosomal dominant, were included in the study. Exons, exon-intron boundaries, and 5’ and 3’ untranslated regions of FTL (NM_000146) were sequenced using the Sanger sequencing method. Results: The female/male ratio of the patients was 7/10. All of the patients were found to have c.-160A>G heterozygous mutation in the FTL gene. Conclusion: In the Turkish population, the prevalence of HFCS is about 1/100,000 and the commonly observed mutation is c.-160A>G mutation.

Abstract
Whole-exome sequencing (WES) is an ideal method for the diagnosis of autosomal recessive diseases. The aim of this study was to evaluate the diagnostic power of WES in patients with autosomal recessive inheritance and to determine the relationship between genotype and phenotype. Retrospective screenings of 24 patients analysed with WES were performed and clinical and genetic data were evaluated. Any pathogenic mutation that could explain the suspected disease in 4 patients was not identified. A homozygous pathogenic mutation was detected in 18 patients. 2 patients had heterozygous mutations. According to this study results, WES is a successful technique to be used at the stage of diagnosis in patients who are accompanied by various degrees of intellectual disability matching the inheritance of the autosomal recessive.

Abstract
The isolation and identification of microorganisms associated with digital dermatitis (DD) in Turkish dairy cattle was investigated using punch skin biopsy samples from typical clinical lesions; they were collected from dairy farms and abattoirs in 5 different geographical locations in Turkey. Morphological characteristics and flagellation types were examined using a transmission electron microscope, and their enzyme profiles by enzyme activation kits; their catalase reaction characteristics were evaluated by the addition of 3% H2O2. Their phylogenies were identified using 16S rRNA and the results compared with known gene bank data. Bacterial cells were 5.0 to 18.2 µm long, 0.2 to 0.5 µm wide, and their minimum number of periplasmic flagellum was 4 (4:8:4) with a maximum of 8 (8:16:8). All isolates were catalase negative. Of the spirochetes isolated and identified, group I organisms showed close similarity with Treponema pedis (99% genetic homology), whereas those in group II were similar to Treponema phagedenis (98% homology). This is the first report of specific sub-groups of Treponema spp., isolated from Turkish dairy cattle presenting with DD lesions, being associated with this disease; these morphotypes were similar to those found globally in housed dairy cattle units and are probably significant microorganisms associated with the aetiopathogensis of this infectious disease causing acute bovine lameness. These results suggest that the distribution of DD-associated treponemes is not specific to particular geographic regions of Turkey.

Abstract
Osteopoikilosis is an inherited condition with autosomal dominant trait resulting in sclerotic foci throughout the skeleton. It has been suggested that loss-of-function mutations of LEMD3 gene located on 12q14.3 result in osetopoikilosis. A bp heterozygote deletion was detected in our patient at the cytosine nucleotide at position 1105 with molecular genetic analysis. Although this mutation has not been previously described, it was considered to be the most likely cause of the disease in our patient due to frame shift and premature stop codon formation. As in our case, three phase bone scintigraphy and whole body imaging did not reflect the true extent of lesion sites and lesion activity. SPECT/CT images could reflect lesion location and activity more accurately, and could be a good alternative for differential diagnosis of unexplained bone pain and sclerotic lesions in one examination.

Abstract
OBJECTIVE The objective of this study was to assess the cognitive performance of endurance athletes and its relation with circulating brain-derived neurotrophic factor (BDNF) and irisin levels. METHODS 26 endurance athletes (14 elite orienteers (mean ± SD: age = 26.33 ± 4.08, body weight = 70.33 ± 4.64, body height = 177.7 ± 6.1), 12 pentathletes (mean ± SD: age = 29.42 ± 5.32, body weight = 74.77 ± 6.59, body height = 180.8 ± 3.8)) and ten sedentary (mean ± SD: age = 27.30 ± 2.06, body weight = 76.65 ± 12.50, body height = 176.9 ± 5.2) men at almost same ages and educational levels participated in this study. Cognitive functions were analyzed with mini-mental-state examination (MMSE) and Isaacs' Set Test of Verbal Fluency (IST) tests. Insulin-like growth factor-1 (IGF-1), BDNF and irisin levels were measured in the blood samples. RESULTS The MSSE and IST scores of the endurance athletes were higher than that of the sedentary control group (P < 0.05). Serum IGF-1 levels were higher in the pentathletes (111.18 ± 22.26 ng mL(-1)) than the orienteers (85.89 ± 19.32 ng mL(-1)) (P < 0.05). Plasma BDNF (2.78 ± 0.81, 4.28 ± 1.03, and 3.93 ± 0.77 ng mL(-1) in the sedentary, orienteers and pentathletes, respectively) and irisin (3.25 ± 0.70, 6.16 ± 0.99, and 6.58 ± 1.09 µg mL(-1) in the sedentary, orienteers and pentathletes, respectively) concentrations of the endurance trained athletes were higher than that of the sedentary control group (P < 0.05). Positive correlation between the cognitive function test results and BDNF and irisin concentrations were observed (P < 0.05). There was also a positive correlation between the circulating irisin and BDNF concentrations (P < 0.05). CONCLUSION These results suggested that irisin and BDNF levels positively correlated with cognition in the endurance trained athletes.

Abstract
BACKGROUND/AIM Small vehicles known locally as pat-pats, which are used in agricultural work, are forbidden in traffic. The inherent instability of the vehicle may result in accidents, both on farmland and in traffic. The aim of this study was to evaluate orthopaedic injuries related to pat-pats. MATERIALS AND METHODS Patients hospitalised for pat-pat accidents in two central hospitals in Samsun between December 2006 and October 2013 were scanned using ICD codes. A total of 46 patients with orthopaedic injuries (43 male, 3 female) with a mean age of 36 ± 13.3 years were evaluated. RESULTS The most injured age group was between 10 and 49 years (n = 40, 87%), and accidents occurred most in summer (n = 30, 65%). Open fractures were determined in 42 (91%) patients. Amputation was necessary in 4 (8%) patients. The hospitalisation period was a mean of 17.1 ± 14 days. A statistically significant relationship was determined between open fracture type and the hospitalisation period (P < 0.001). CONCLUSION As most of the orthopaedic injuries related to home-made agricultural machines are open fractures, it is important to guard against these types of injuries. The regulations that these machines are not used in traffic should be enforced and safer practices should be applied for use in agriculture.

Abstract
PURPOSE There is currently no gold standard treatment for unstable intertrochanteric fractures of the elderly. Internal fixation and hemiarthroplasty are two common treatment methods but studies comparing the functional outcomes of these procedures in the elderly are limited. This study evaluates the functional outcomes of hip fracture patients treated either with internal fixation or hemiarthroplasty. METHODS Eighty-six elderly (>60 years) patients who presented with isolated, unstable intertrochanteric fractures between 2009 and 2013 were included in the study. According to the classification of Association for Osteosynthesis/Orthopaedic Trauma Association; 12 of the patients had a 31A1.3 fracture type, 36 of the patients had 31A2.2 and 19 had 31A2.3 fracture type, 12 had 31A3.1 and seven had 31A3.3 fracture. Forty-two of 86 hip patients (Group 1) were treated with intramedullary nailing and antirotator proximal femoral nail implant (TST, Turkey), and 44 (Group 2) were treated with cementless bipolar hemiarthroplasty. Preoperative social function (Jensen) score, EQ-5D index score and mobility (Palmer/Parker) scores were obtained. Five dimensions of EQ-5D were obtained at every follow-up visit until 24 months postoperative. RESULTS There was no statistically significant difference between two groups according to preoperative demographic variables, including mean age and sex and Jensen, Palmer/Parker,EQ-5D index, five dimensions of EQ-5D and American Society of Anesthesiologists scores. At end of 24 months follow-up, health-related quality of life had increased more in Group 1 and they reported better social functioning and mobility scores (p<0.01). CONCLUSION Internal fixation resulted in better social functioning and mobility scores compared with cementless bipolar hemiarthroplasty at the end of 24 months in treatment of unstable pertrochanteric hip fracture in the elderly.

Abstract
Total hip arthroplasty for severe developmental dysplasia of the hip is a technically challenging procedure. Subtrochanteric femoral osteotomy enables reducing the femoral head and restoring abductor muscle strength without compromising proximal femoral bone stock in advanced dysplasia.We aimed to retrospectively evaluate Crowe type III or IV developmental dysplasia of the hip who underwent reconstruction with cementless total hip arthroplasty combined with a transverse subtrochanteric femoral osteotomy. Sixty hips of 52 patients (11 male, 49 female) with Crowe type III (n: 37) or IV (n: 23) developmental dysplasia of the hip were included. The average age was 51.4 years. Surgery was performed in lateral decubitis position with posterolateral approach. Subtrochanteric transverse femoral osteotomy were used with cementless components. 40 of the femoral components were Secur-Fit type, and 20 of them were secur-fit plus max type. Ceramic-ceramic coupling was used in 24 cases and metal-polyethylene coupling was used in 36 cases. Merle D'Aubigne and Harris Hip score were used to rate the clinical outcome at the final follow up. All femoral shortening osteotomies were united at a mean of 5.7 months. Mean Merle D'Aubigne pain score was increased from 3.1 to 5.4, and mean Harris Hip score improved from 39 to 92.8, postoperatively (p<0.01). There was no significant difference in time to union between different types of stems. 4 femoral stems had asymptomatic radiolucent lines. There was no significant difference in time to union between different types of stems.

Abstract
In the pathogenesis of peripheral nerve injury, mechanical as well as vascular pressure, and chemical reasons play a role. In the applications of peripheral nerve block, there can be mechanical injury due to the type of needle and intrafascicular injections. In humerus fractures, nerve injury can be seen due to the surgical retractions and close proximity of the nerves with the bone. In addition, trauma may be the reason for posttraumatic nerve injury. In this presentation, we discussed the causes of postoperative nerve damage, which is seen after the operation of the distal humerus fracture.

Abstract
BACKGROUND Amputation of limb is essential in certain conditions; however, it may have significant impact on the patient's psychological condition. The present study investigates psychological responses of upper limb (UL) amputees versus lower limb (LL) amputees regarding prosthetic adjustment, social discomfort, depression, and body image anxiety. METHODS Traumatic major amputations of 20 upper and 38 lower extremities of 58 patients who were currently using prosthesis were included. 12 of UL amputations were of dominantly used limb. Seven of the UL amputations, and nine of the LL amputations were female. The Trinity Amputation and Prosthesis Experience Scales was used for adjustment, restriction, and satisfaction. Anxiety and depression levels were assessed using Hospital Anxiety and Depression Scale (HADS). Body image disturbance and social discomfort were assessed with Amputation Body Image Scale-Revised (ABIS-R) and Social Discomfort Score, respectively. RESULTS 58 individuals with 20 UL and 38 LL amputations were included. Mean age of UL amputees was 44.76 ± 12.26 and 49.1 ± 14.3 years for LL amputees. Mean time of daily prosthesis use was 11.35 ± 4.8 and 11.52 ± 4.7 h, respectively. Mean time since amputation was 35.4 ± 14.3 and 36.05 ± 13.6 months; length of prosthesis use time was 24.8 ± 13.4 and 23.9 ± 15.12 months, respectively. Social adjustment and adjustment to limitation subscales had significantly higher scores in LL amputees (p < 0.001). There was statistically significant difference between mean HADS depression and anxiety scores (p < 0.001). Mean total ABIS-R score indicated significantly greater body image disturbance for UL amputees (p < 0.001). CONCLUSION Well-adjusted LL prosthesis probably has better cosmetic appearance compared to that of UL prosthesis and perception of cosmetic appearance may be the key factor that leads to increased levels of body image anxiety and social discomfort.

Abstract
UNLABELLED PURPOSE Of THE STUDY To compare the clinical results of clavicular fractures operated by superior locking plate using either horizontal or vertical incision by physical examination and nerve conduction tests. MATERIAL AND METHODS Between January 2010 and January 2013, 63 patients with displaced midshaft clavicle fracture were treated with superior locking plate (22 female, 41 male) with either horizontal (n = 38) or vertical incisions (n = 25). Mean interval between trauma and surgery was 3 days (1 to 8 days). Electrodiagnostic tests were performed to 15 patients who felt numbness across their shoulder or chest and ASES test was performed to each of the patient 12 weeks postoperatively. IBM SPSS Statistics 22 (IBM SPSS, Türkiye) programme was used for statistical analysis. Student t-test was used for comparison of normally distributed parameters (quantity) and continuity (yates) test was used. p < 0.05 was accepted to be statistically signifiant. RESULTS 8 patients of the horizontal incision group and 7 patients of the vertical incision group described numbness across their shoulders. 14 patients had abnormal sensorial electrodiagnostic fidings. Comparison of electrodiagnostic fidings did not reveal any statistical signifiance. The mean ASES score of the affected shoulder was 76.39 ±1.20 in the horizontal group, in the vertical group it was found to be 79.00 ± 2.5 ( p < 0.01). CONCLUSIONS Electrodiagnostic study revealed similar results in both groups. According to these results, signifiant difference in mean ASES scores of both groups was not related to sensorial injury of the supraclavicular nerve.

Abstract
OBJECTIVE The aim of this study was to detect the incidence of estrogen receptors in human hip joint capsule and ligamentum teres. METHODS The study included biopsies of the ligamentum capitis femoris (LCF) and hip joint capsule from 15 patients undergoing hip surgery for developmental dysplasia of the hip (DDH) and from the control hips of 15 cases of intrauterine fetal death. Mean age was 10.3 (range: 6 to 18) months at the time of surgery. Full-thickness 1x1 cm anterior capsule and LCF portions were taken as biopsy specimens. An immunohistochemical study using monoclonal antibody against estrogen receptors was performed to identify the rate of target estrogen cells in the hip joint capsule and LCF. RESULTS Estrogen receptor (ER) staining rates were 1.6±0.2% for the LCF and 1.3±0.2% for the hip joint capsule in the control groups, and 2.5±0.3% for the LCF and 2.0±0.3% for the hip joint capsule in the DDH groups. Estrogen receptor staining rates in the LCF and hip joint capsule control groups were significantly lower than that in the DDH groups (p<0.001). In both groups, ER rates were significantly lower in the hip joint capsule than in the LCF (p<0.01). CONCLUSION The high rate of ERs in the LCF and hip joint capsule appears to support the effect of estrogen in the etiology of the DDH.

Abstract
Epistaxis is a very common medical problem in otolaryngology practice and can usually be controlled with conservative interventions. Rarely, uncontrolled and life threatening epistaxis occurs. We present the case of a 29-year-old male who developed intractable intermittent epistaxis due to post-traumatic pseudoaneurysms arising from the cavernous segment of the left internal carotid artery. The patient was successfully treated with endovascular embolization.

Abstract
Tick-borne diseases are seen all over the world and their importance rises increasingly. It is noticeably important that disease and death rates due to tick-bites in our country in different areas increased in 2008. In Turkey, the numbers of diseases which are transmitted by ticks are considerably large and all of them are not detected. Reports of isolated facial paralysis cases due to tick infestation in the ear are infrequent in literature. The development of isolated facial paralysis due to ticks can be explained by several theories. This article reports a case report of a 3 year- old girl who was bought to our clinic with severe left ear pain and paresthesia on the left half of her face. She couldn't close her left eye and she lisped. The tick was removed from her external auditory canal surgically.

Abstract
OBJECTIVE In recent years, thyroid cancer has been at the forefront of molecular pathology as a result of the consequences of the Chernobyl disaster and the recognition of the role of RET/PTC rearrangements in papillary thyroid carcinomas (PTCs). Correlation of RET/PTC expression with clinical outcome is controversial. This study aims to identify the prevalence of RET/PTC oncogene expression in Turkey, and to investigate the correlation between RET/PTC oncogene expression and the known prognostic factors of PTC in 101 patients. METHODS The RET rearrangements were examined by means of reverse transcriptase-polymerase chain reaction analysis, with primers flanking the chimeric region. Statistical evaluation was performed by using Independent samples t-test, One-sample Chi-square test and Pearson Chi-square or Fisher's Exact Test. RESULTS RET/PTC was determined positive in 67(66.3%) of totally 101 patients (p<0.001). RET/PTC1 in 32(31.7%), RET/PTC3 in 21(20.8%), RET/PTC1+RET/PTC3 both in 10(9.9%) patients were found to be positive. There was RET/PTC2 positiveness in two patients, RET/PTC2,3 positiveness in one patient, and RET/PTC1,2,3 positiveness in one patient. No statistical difference was found between RET/PTC1 and RET/PTC3. None of genetico-clinical analyses showed any significant association between RET/PTC expression and the clinical and pathological features of the cancers. CONCLUSION While this prevalence of the RET/PTC is less than RET/PTC frequency seen after Chernobyl in Belarus, its prevalence in our region is also high (66.3%). As a result, no significant correlation was found in between prognosis and RET/PTC frequency.

Abstract
OBJECTIVE Persistence of the left superior vena cava (PLSVC) is a congenital anomaly resulting from failure of degeneration of the left cardinal vein. The prevalence of this anatomical variant is approximately 0.3% in the general population. The aim of this study was to determine the prevalence of the persistence of the left superior vena cava in order to avoid potential complications. SUBJECTS AND METHODS The study was conducted during a five-year period in 152 patients (64 males, 88 females) aged 1-65 years who underwent cardiac surgery for congenital heart diseases. RESULTS The persistence of the left superior vena cava was found in 5 of 152 patients (3.3%). All persistent left superior vena cavae opened into the coronary sinus. Furthermore, the coronary sinus was enlarged in all patients. The right superior vena cava was absent in one of the five cases (20%) in this study. CONCLUSION This anatomical variant must be recognized to avoid the potential complications.
