Abstract
OBJECTIVE Interleukin 34 (IL-34) is a molecule whose expression is increased in conditions such as autoimmune disorders, inflammation, and infections. Our study aims to determine the role of IL-34 in the diagnosis, follow-up, and prognosis of Coronavirus Disease-19 (COVID-19). METHOD A total of 80 cases were included in the study as 40 COVID-19 positive patient groups and 40 COVID-19 negative control groups. The COVID-19-positive group consisted of 20 intensive-care unit (ICU) patients and 20 outpatients. Serum IL-34, c-reactive protein (CRP), ferritin, D-dimer, troponin I, hemogram, and biochemical parameters of the cases were studied and compared between groups. RESULTS IL-34 levels were significantly higher in the COVID-19-positive group than in the negative group. IL-34 levels increased in correlation with CRP in predicting the diagnosis of COVID-19. IL-34 levels higher than 31.75 pg/m predicted a diagnosis of COVID-19. IL-34 levels did not differ between the outpatient and ICU groups in COVID-19-positive patients. IL-34 levels were also not different between those with and without lung involvement. CONCLUSION While IL-34 levels increased in COVID-19-positive patients and were successful in predicting the diagnosis of COVID-19, it was not found to be significant in determining lung involvement, risk of intensive care hospitalization, and prognosis. The role of IL-34 in COVID-19 deserves further evaluation.

Abstract
INTRODUCTION The prevalence rates of hepatosteatosis and gallstones are increasing owing to the multifactorial causes of chronic kidney disease, and the prevalence may change with the availability of different forms of renal replacement therapy. We aimed to determine the incidence or prevalence rates of hepatosteatosis, cholelithiasis, and acute cholecystitis in patients with chronic kidney disease and compare them between renal replacement therapy modalities. METHODS A total of 270 patients (90 with chronic kidney disease stages III-V, 90 undergoing peritoneal dialysis, and 90 undergoing hemodialysis) were included and categorized into the pre-dialysis, hemodialysis, and peritoneal dialysis groups. The patients were questioned about previous gallbladder surgeries and chronic diseases. The results of abdominal ultrasonography, tomography, and magnetic resonance imaging were retrospectively evaluated with respect to the findings on the hepatobiliary system. Hepatosteatosis and cholelithiasis were diagnosed by expert radiologists on the basis of abdominal ultrasonography, tomography, and magnetic resonance imaging findings. The prevalence rates of hepatosteatosis, cholelithiasis, and other liver findings were compared between the groups. FINDINGS Hepatosteatosis and cholelithiasis were detected in 16.7% and 21.5% of the 270 cases, respectively. Hepatosteatosis was present in 17.8%, 25.6%, and 6.7% of patients in the pre-dialysis, hemodialysis, and peritoneal dialysis groups, respectively. The prevalence of hepatosteatosis was significantly higher in patients undergoing hemodialysis than in patients undergoing peritoneal dialysis (p = 0.002). However, no statistically significant difference was found between the peritoneal dialysis and pre-dialysis groups or between the hemodialysis and pre-dialysis groups (p >0.05). The prevalence rates of cholelithiasis were 15.6%, 28.9%, and 20.0%, in the pre-dialysis, hemodialysis, and peritoneal dialysis groups, respectively, and there were no statistically significant differences among the groups. The incidence of acute cholecystitis was significantly higher in the hemodialysis group than in the pre-dialysis group (p = 0.006). DISCUSSION Our study showed that the hepatobiliary system is frequently affected in chronic kidney disease and that the findings may differ depending on the renal replacement therapy modality.

Abstract
BACKGROUND Intestinal barrier dysfunction in acute pancreatitis (AP) may progress to systemic inflammatory response syndrome (SIRS) and multi-organ failures by causing bacterial translocation. Larazotide acetate (LA) is a molecule that acts as a tight junction (TJ) regulator by blocking zonulin (Zo) receptors in the intestine. AIMS In our study, we aimed to investigate the effects of LA on intestinal barrier dysfunction and bacterial translocation in the AP model in rats. METHODS Thirty-two male Sprague-Dawley rats were divided into 4 groups; control, larazotide (LAR), AP, and AP + LAR. The AP model was created by administering 250 mg/100 g bm L-Arginine intraperitoneally 2 times with an hour interval. AP + LAR group received prophylactic 0.01 mg/mL LA orally for 7 days before the first dose of L-Arginine. For intestinal permeability analysis, fluorescein isothiocyanate-dextran (FITC-Dextran) was applied to rats by gavage. The positivity of any of the liver, small intestine mesentery, and spleen cultures were defined as bacterial translocation. Histopathologically damage and zonulin immunoreactivity in the intestine were investigated. RESULTS Compared to the control group, the intestinal damage scores, anti-Zo-1 immunoreactivity H-Score, serum FITC-Dextran levels and bacterial translocation frequency (100% versus 0%) in the AP group were significantly higher (all p < 0.01). Intestinal damage scores, anti-Zo-1 immunoreactivity H-score, serum FITC-Dextran levels, and bacterial translocation frequency (50% versus 100%) were significantly lower in the AP + LAR group compared to the AP group (all p < 0.01). CONCLUSIONS Our findings show that LA reduces the increased intestinal permeability and intestinal damage by its effect on Zo in the AP model in rats, and decreases the frequency of bacterial translocation as a result of these positive effects.

Abstract
Thyroid nodules are one of the most common health problems in the community. Although most of the nodules are benign, Fine needle aspiration biopsy (FNAB) is requested due to malignancy concerns. In this research, the aim was to make a comparison of the results of thyroid ultrasonography (USG) and FNAB for thyroid nodules. This study was conducted retrospectively on the data of 532 patients. Detail Edu ultrasonographic assessment was conducted before the FNAB procedure and FNAB was performed by an endocrinology specialist. FNAB results and Thyroid USG features were compared, and thyroid FNAB results were graded using the classification of World Health Organization Bethesda-2017. The average age of the individuals included in the research was 49.99 ± 13.65 (min = 18-max = 97). According to the 2017 Bethesda classification, 74.6% of FNAB results were benign, 16% follicular lesion of undated mined significance or A type of undated mined significance, 0.9% were malignant, and 1.1% were suspicious for malignancy. When USG findings were compared according to FNAB results, it was found that malignant lesions were significantly higher in single nodules (non- cystic and non- mixed lesions). Lesions with a single nodule on USG were found to be 3.6 times more likely to be malignant (OR 95% CI: 1.172-11.352). The gold standard method for the diagnosis the presence of thyroid nodules is thyroid fine needle aspiration biopsy with ultrasound guidance. Taking samples from the correct nodule and component increases its value. The presence of a single nodule from the thyroid USG features was found to be an important predictor of malignancy according to the biopsy results.

Abstract
We describe a male with a variant Klinefelter syndrome (KS), and trisomy Xq resulting from an isochromosome Xq [47,Xi(Xq)Y]. He had many characteristics of classical KS: bilateral atrophic testes and microcalcifications, normal masculinization, azoospermia, hypergonadotropic hypogonadism, elevated FSH and LH, normal intelligence and normal androgenization, but his stature was not increased. Ultrasonographic evaluation also revealed parenchymal alterations secondary to previous epididymo-orchitis. After initial evaluation the patient underwent incisional biopsy of testes which showed tubular hyalinisation, Leydig cell hyperplasia and Certoli cell syndrome. The i(Xq) was found in all cells analyzed. These findings indicate that extra copies of the long arm of X have phenotypic expression, even though activated only in early development. In conclusion, review of literature on 20 adult patients supports the view that the presence of an isochromosome Xq in KS has a favorable prognosis in terms of normal mental development and normal stature.

Abstract
Nitroimidazole derivatives are commonly used in the treatment of protozoal and anaerobic infections, and reports of their hepatotoxicity are rare. We report a case of severe hepatitis due to the long-term (8 weeks) use of ornidazole. A 27-year-old woman presented for evaluation of elevated serum transaminase and total bilirubin levels. Liver biopsy revealed portal inflammation, hepatocellular and canalicular cholestasis, porto-portal and portocentral bridging fibrosis, and a tendency to form nodules. No aetiological factors associated with chronic liver disease were identified. The abdominal ultrasonographic findings were compatible with chronic liver disease. We therefore made the diagnosis of severe hepatitis resulting from the long-term use of ornidazole. We conclude that nitroimidazole derivatives may lead to serious liver damage, especially in female patients.

Abstract
We present a patient with acromesomelic chondrodysplasia and genital anomalies caused by a novel homozygous mutation in BMPR1B, the gene coding for bone morphogenetic protein receptor 1B. The 16 year old girl, the offspring of a multiconsanguinous family, showed a severe form of limb malformation consisting of aplasia of the fibula, severe brachydactyly, ulnar deviation of the hands, and fusion of carpal/tarsal bones. In addition, she presented with hypoplasia of the uterus and ovarian dysfunction resulting in hypergonadotrophic hypogonadism. Mutation analysis of BMPR1B revealed a homozygous 8 bp deletion (del359-366). This mutation is expected to result in a loss of function and is thus different from the heterozygous missense mutations in BMPR1B recently shown to cause brachydactyly type A2 through a dominant negative effect. The patient's skeletal phenotype shows an overlap with the clinical spectrum of the acromesomelic chondrodysplasias of the Grebe, Hunter-Thompson, and DuPan types caused by homozygous mutations in the gene coding for growth differentiation factor 5 (GDF5) which is a high-affinity ligand to BMPR1B. However, the phenotype described here differs from GDF5 associated chondrodysplasias because of the additional presence of genital anomalies and the distinct limb phenotype.

Abstract
BACKGROUND AND STUDY AIMS Bacterial translocation (BT) has been implicated in the development of infectious complications in many serious clinical conditions such as fulminant hepatic failure (FHF). We aimed to investigate the effects of Gingko biloba (GB), vitamin E (Vit E) and melatonin on intestinal oxidative damage and BT in thioacetamide (TAA)-induced FHF in rats. MATERIALS AND METHODS A total of 42 rats were divided into five groups. Group 1 (n = 8) was the control group. Group 2 (n = 10) was the TAA group, in which rats received 350 mg/kg TAA daily by the intraperitoneal (ip) route for 3 days. Oral 100 mg/kg GB per day was administered to group 3 (n = 8), oral 200 mg/kg Vit E per day to group 4 (n = 8) and ip 3 mg/kg melatonin per day to group 5 (n = 8) 48 h prior to the first TAA injection and was continued for 5 consecutive days. RESULTS When compared with the control group, serious hepatic and intestinal oxidative damage, increased Escherichia coli counts in ileal aspirates and high BT frequencies were observed in the TAA group (all p < 0.0001). Only GB treatment attenuated hepatic oxidative damage (p < 0.0001). There was no difference in intestinal oxidative damage, E. coli counts in ileal aspirates and BT frequency between TAA and the other antioxidant treatment groups (p > 0.05). CONCLUSION Our results suggest that intestinal oxidative damage plays a major role in the development of BT by disrupting the barrier function of intestinal mucosa.
