The objective of the present study was to report the incidence, demographic characteristics, and various presentations of tuberculosis in solid-organ transplant recipients. Materials and Methods: We evaluated a total of 999 patients (male/female = 665/334, 661 renal and 338 liver transplants) who underwent solid-organ transplant between 2003 and 2013. The medical records of all patients were retrospectively reviewed. Patients' demographics, transplant type, primary site of tuberculosis specimen culture and pathology results, chest radiograph, and thoracic computed tomography findings, total blood count and chemistry were all recorded. Results: Among the 999 subjects, 19 patients (1.9%) (male/female: 15/4, mean +/- SD age, 42 +/- 18.5 y) were diagnosed with tuberculosis. The majority of patients (85%) were diagnosed with tuberculosis within 6 months after transplant, and 15% were diagnosed within 3 months. Most diagnoses of tuberculosis were based on histopathologic examination of biopsy material. Of these patients, 9 were diagnosed with pulmonary tuberculosis, 8 had extrapulmonary tuberculosis, and 2 had both. Nontuberculosis mycobacteria infections were detected in 3 patients. Conclusions: Even with a negative exposure history, tuberculosis can manifest as different clinic presentations in solid-organ transplant patients on immunosuppressive drugs, particularly in the first 6 months after transplant. Therefore, clinicians should always consider tuberculosis as the potential cause of an infectious disease with unknown cause to successfully diagnose and manage solid-organ transplant recipients.Item A 10-year retrospective analysis of intimate partner violence patients in the emergency department(2022) Kavak, Nezih; Kavak, Rasime Pelin; Ozdemir, Meltem; Sever, Mustafa; Ertan, Nurcan; 35652880BACKGROUND: Intimate partner violence (IPV) is an important human rights problem faced by one in three women worldwide. The aim of this study is to evaluate the demographic, trauma, and radiological characteristics of patients admitted to a tertiary emergency department due to IPV. METHODS: Sociodemographic characteristics (age, gender, education level, and marital status), trauma characteristics (severity, type, and location), radiological imaging findings (radiography, computed tomography, and magnetic resonance imaging) of patients diagnosed with IPV were evaluated. RESULTS: In the study, 1225 patients were evaluated, and 98.7% of them were women (mean age 35 [IQR: 17] years). Of the patients, 63.1% were high school and university graduates. The rate of married women was 74.6%. No relationship was found between gender, age, educational status, and marital status (p>0.05). Most of the traumas were minor (85.4%) and blunt (81.9%) trauma, and the most common types of trauma were kicking (49.9%) and punching (47.3%). It was found that the most frequently affected areas of the patients were the head and neck (76.7%), and the frequency of pelvic trauma was high in male patients (p<0.05). The most common bone fracture was nasal (40.5%) followed by ulna fractures (14.5%). The left-sided diaphyseal fractures were the most common in patients exposed to IPV. In our study, the frequency of mortality was 12.9%, and it was found to be significantly higher in males (p<0.05). CONCLUSION: Female patients are more frequently exposed to IPV. Specific injury characteristics can be detected in patients diagnosed with IPV and old fractures detected in these patients should alert the clinician about IPV.Item 17 Years Of Pediatric Liver Transplantation Experience For Cirrhosis And Hepatocellular Carcinoma(2022) Ozcay, Figen; Sezer, Oya Balci; Sarialioglu, Faik; Boyvat, Fatih; Coskun, Mehmet; Reyhan, Nihan Haberal; Haberal, Mehmet; https://orcid.org/0000-0002-3462-7632; AAJ-8097-2021Item The 2-Stage Liver Transplant: 3 Clinical Scenarios(2015) Gedik, Ender; Bicakcioglu, Murat; Otan, Emrah; Toprak, Huseyin Ilksen; Isik, Burak; Aydin, Cemalettin; Kayaalp, Cuneyt; Yilmaz, Sezai; 0000-0001-9293-8116; 0000-0002-2395-3985; 0000-0002-7175-207X; 0000-0003-4657-2998; 25894175; ABB-5579-2020; AAH-1764-2021; AAN-4023-2020; A-6657-2018; ABI-2971-2020The main goal of 2-stage liver transplant is to provide time to obtain a new liver source. We describe our experience of 3 patients with 3 different clinical conditions. A 57-year-old man was retransplanted successfully with this technique due to hepatic artery thrombosis. However, a 38-year-old woman with fulminant toxic hepatitis and a 5-year-old-boy with abdominal trauma had poor outcome. This technique could serve as a rescue therapy for liver transplant patients who have toxic liver syndrome or abdominal trauma. These patients required intensive support during long anhepatic states. The transplant team should decide early whether to use this technique before irreversible conditions develop.Item 2019 Expert opinion on biological treatment use in inflammatory bowel disease management(2019) Toruner, Murat; Akpinar, Hale; Akyuz, Filiz; Dagli, Ulku; Hamzaoglu, Hulya Over; Tezel, Ahmet; Unsal, Belkis; Yildirim, Suleyman; Celik, Aykut Ferhat; 32207688Item The 2100 Mhz Radiofrequency Radiation of A 3G-Mobile Phone and The DNA Oxidative Damage in Brain(2016) Sahin, Duygu; Ozgur, Elcin; Guler, Goknur; Tomruk, Arin; Unlu, Ilhan; Sepici-Dincel, Aylin; Seyhan, Nesrin; 26775761We aimed to evaluate the effect of 2100 MHz radiofrequency radiation emitted by a generator, simulating a 3G-mobile phone on the brain of rats during 10 and 40 days of exposure. The female rats were randomly divided into four groups. Group I; exposed to 3G modulated 2100 MHz RFR signal for 6 h/day, 5 consecutive days/wk for 2 weeks, group II; control 10 days, were kept in an inactive exposure set-up for 6 h/day, 5 consecutive days/wk for 2 weeks, group III; exposed to 3G modulated 2100 MHz RFR signal for 6 h/day, 5 consecutive days/wk for 8 weeks and group IV; control 40 days, were kept in an inactive exposure set-up for 6 h/day, 5 consecutive days/wk for 8 weeks. After the genomic DNA content of brain was extracted, oxidative DNA damage (8-hydroxy-2'deoxyguanosine, pg/mL) and malondialdehyde (MDA, nmoL/g tissue) levels were determined. Our main finding was the increased oxidative DNA damage to brain after 10 days of exposure with the decreased oxidative DNA damage following 40 days of exposure compared to their control groups. Besides decreased lipid peroxidation end product, MDA, was observed after 40 days of exposure. The measured decreased quantities of damage during the 40 days of exposure could be the means of adapted and increased DNA repair mechanisms. (C) 2016 Elsevier B.V.

The deletion typically involves the terminal band 22q13.3 and has been associated with both familial and de-novo translocations. We report the case of an 11-year-old Turkish girl with 22q13.3 deletion syndrome presenting with repeated seizures during the course of a rubella infection. We also review the clinical features of 22q13.3 deletion syndrome and emphasize the importance of considering a rare microdeletion syndrome for idiopathic mental retardation when results of a routine karyotype analysis are normal. To the best of our knowledge, this is the first reported case of a Turkish patient with isolated 22q13.3 deletion syndrome.Item 25 Oh Vitamin D Levels and Effects on Children Who Underwent Liver Transplantation(2017) Gulsen, M.; Baris, Z.; Ozcay, F.; 0000-0003-4494-9536; 0000-0002-5214-516X; AAX-9638-2021; AAB-4153-2020; ABG-5684-2020Item 3 Year Follow Up Results of Heart Failure Patients Included in the Journey HF-TR Study(2020) Sabanoglu, C.

Phenotypic features of the syndrome have not been fully characterized due to the new definition and rarity. Facial dysmorphology, musculoskeletal anomalies, cardiovascular abnormalities, gastrointestinal abnormalities, and dental abnormalities can be seen.Case. A 28-month-old male patient was brought to the child and adolescent psychiatry clinic with a complaint of speech delay. He had mild dysmorphic symptoms. He was also sensitive to voice and often covered his ears. Balloon valvuloplasty was performed on the postnatal 28th day due to severe pulmonary stenosis. While karyotype was found to be normal, in array-Comparative genomic hybridization (aCGH), copy loss was detected in the long arm of chromosome 3 (arr[hg19] 3q29[196,209,689-197,601,344]x1), which contains approximately 1.4 Mb harboring 30 genes. Genetic counseling was given to the family of the patient who was diagnosed with 3q29 microdeletion syndrome.Conclusions. In conclusion, we present 3q29 microdeletion syndrome with global developmental delay (GDD), dysmorphic face, hyperacusis, scoliosis, and severe pulmonary stenosis. Performing genetic analysis in patients with developmental delay and congenital heart disease (CHD) for which the cause cannot be explained will prevent these rare diseases from being missed, and the characteristics of the diseases will be better characterized with the reported cases.Item 46,XY Partial gonadal dysgenesis; diagnosis and long-term outcome at puberty(2022) Guven, Ayla; 0000-0002-2026-1326; I-8448-2019Item 68Ga-DOTATATE PET/CT Imaging in Medullary Thyroid Carcinoma Patients with Raised Serum Calcitonin(2018) Torun, N.; Erhamamci, S.; Reyhan, M.; Yapar, A.

Visceral adipose tissue (VAT) is a strong predictor of carbohydrate metabolism disorders. Abdominal bioelectrical impedance analysis (A-BIA) is a simple method for the measurement of VAT and is a promising tool in screening and follow-up of abdominal obesity. However the role of A-BIA in dieting individuals has not been evaluated adequately in longitudinal follow-up studies. Objective. The aim of this study is to determine the role of A-BIA in identifying the changes in metabolic predictors after diet and/or exercise therapy. Design. All patients who sought weight loss treatment underwent baseline assessment and were prescribed a program of diet. After a mean follow-up of 3.2 months, data were analyzed. Subjects and Methods. Ultimately, 103 participants who reported adhering to the diet, enrolled to the study. We tested associations between changes in body composition measures and changes in laboratory measures using correlations and multivariate linear regression analysis. Results. Mean loss of body weight was 3.4 +/- 2.8 kg. All but waist-to-hip ratio, low-density lipoprotein cholesterol and high-density lipoprotein cholesterol levels changed significantly (p<0.001). Decreases in body weight, body mass index (BMI), and VAT level significantly correlated with decreases in fasting blood glucose, fasting insulin level, and HOMA-IR score (r=0.230-0.371). In multiple linear regression analysis changes in BMI and VAT significantly correlated with change in HOMA-IR score (F(7.93)=2.283, p=0.034, R2=0.147). Conclusion. Decreases in BMI and VAT, as determined by A-BIA, were predictors of changes in metabolic laboratory measures. A-BIA is useful for follow-up of patients receiving diet therapy for weight loss.Item Abdominal CT Findings in Patients with Primary Lymphoma Causing Small Bowel Obstruction(2017) Karadeli, Elif; Erbay, Gurcan; Parlakgumus, Alper; Yabanoglu, Hakan; 0000-0002-0352-8818; 0000-0002-1706-8680; 0000-0002-1161-3369; 29132484; AAK-5399-2021; AAK-5370-2021; AAJ-7865-2021The purpose of this study was to investigate retrospectively CT findings in patients with primary lymphoma causing small bowel obstruction. CT scans of 11 patients with small bowel lymphoma were separately analysed in terms of affected section of the small bowel, focality, wall thickness, pattern and degree of contrast enhancement, lymphadenopathy, organ involvement, perforation, and the presence of intraabdominal fluid. Eight patients had diffuse large B-cell lymphoma, and one patient each had marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT), T-cell lymphoma, and anaplastic T-cell lymphoma. Affected sections of the bowels involved were jejunum (n=5, 45.4%), ileum (n=2, 18.1%), and one case (9%) each of distal ileum, distal jejunum, distal jejunum and ileum, and distal jejunum and colon. Primary gastrointestinal (GI) lymphoma is an uncommon disease, that may lead to small bowel obstruction sometimes.Item Abdominal Ischemia-Reperfusion Induced Cardiac Dysfunction Can Be Prevented by MitoTEMPO(2021) Akkoca, Ahmet; Celen, Murat Cenk; Tuncer, Seckin; Dalkilic, Nizamettin; 33761811Background Cardiac dysfunction is secondary to acute mesenteric ischemia (AMI) and abdominal aortic aneurysms (AAA). The underlying cause of distant organ damage in the heart is the formation of oxidative stress caused by ischemia-reperfusion. In this study, we investigated the possible protective effects of a novel mitochondria-targeted antioxidant MitoTEMPO on contractile dysfunction and structural defects of the rat papillary muscle caused by abdominal ischemia-reperfusion (AIR). Methods and Results In the experiments, adult Wistar-Albino rats were used and animals were divided randomly into 3 groups; sham-operated group (SHAM), an IR group that had aortic cross-clamping for 1 h followed by 2 h reperfusion, and a third group that received protective 0.7 mg/kg/day MitoTEMPO injection for 28-day before IR. As a result, it was observed that MitoTEMPO injection had a protective effect on the mechanical activities and structural properties of the papillary muscle impaired by AIR. Our study also showed that AIR disrupted the contractile function of the papillary muscle for each stimulation frequency and post-potentiation responses tested. This is common for each measured and calculated mechanical parameter and MitoTEMPO injection showed its protective effects. Conclusion Consequently, calcium homeostasis seems to be impaired by AIR, and MitoTEMPO may exert its protective effect through energy metabolism by directly targeting the mitochondria.
