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 2019 Turkish Hypertension Consensus Report(2019) Aydogdu, Sinan; Guler, Kerim; Bayram, Fahri; Altun, Bulent; Derici, Ulver; Abaci, Adnan; Tukek, Tufan; Sabuncu, Tevfik; Arici, Mustafa; Erdem, Yunus; Ozin, Bulent; Sahin, Ibrahim; Erturk, Sehsuvar; Bittigen, Atilla; Tokgozoglu, Lale; 31483311The Turkish Hypertension Consensus Report was prepared for the first time in 2015 to adapt the European and American international guidelines to our clinical practice and to create a practical report that could be a basic reference for all physicians dealing with hypertensive patients. This report, which was prepared by a committee with representation from 5 leading hypertension associations, has been accepted and is widely used. New clinical studies in hypertension literature and updated international guidelines since 2015 have demanded an update of the Turkish Hypertension Consensus Report as well. In this updated 2019 report, blood pressure levels were classified as Normal, Elevated, Stage 1, and Stage 2 hypertension. A new section was added for secondary hypertension. It was specified that drug treatment may be initiated with any 1 or a combination of 4 groups of drugs (diuretics, calcium channel blockers, angiotensin-converting enzyme [ACE] inhibitors, and angiotensin receptor blockers [ARBs]), except a combination of an ACE inhibitor and an ARB. It was emphasized that beta-blockers may be a first choice for hypertension treatment in diseases such as atrial fibrillation, heart failure, and coronary artery disease. The initial recommendation for hypertension treatment is a combination therapy in patients with a blood pressure level >= 150/90 mmHg. Target blood pressure values were redefined according to age and the presence of comorbidities. The hypertension treatment algorithm was renewed; it is proposed that drug therapy can also be initiated with a risk-based approach for the group with an elevated blood pressure (systolic blood pressure: 120-139 mmHg, diastolic blood pressure: 80-89 mmHg). The threshold clinic systolic blood pressure level was reduced from 160 mmHg to >= 150 mmHg for the initiation of drug therapy in individuals 80 years of age or more. The section on the treatment of special groups has now been expanded to include pregnancy and lactation. As in the previous report, in this update, practical recommendations for the most common cases seen in the clinic were the goal, rather than a comprehensive report that addresses all aspects of hypertension. This report has evidence-based recommendations for most patients; however, it should be kept in mind that there may be differences from 1 patient to another and that physicians should take an individualized approach according to a good clinical evaluation.Item 2020 ESC Core Curriculum for the Cardiologist: What has changed?

Bahar Sempozyumu Odyogram Ötesi İşitme Problemleri(2024) Üniversitesi, BaskentItem 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 65 Yaş üstü diyabeti olan ve olmayan hastalarda sarkopeni görülme sıklığı ve özelliklerinin araştırılması(Başkent Üniversitesi Tıp Fakültesi, 2022) Göçmen, Emre Ruhi; Kut, AltuğYaşlı nüfusunun artış göstermesi ve diyabet prevalansının her geçen gün artması, yaşlı diyabet hastalarının sayısında hızlı bir artışla sonuçlanmaktadır. Normal popülasyona göre diyabetlilerde sarkopeni prevalansı daha yüksektir ve yaşam kalitesini olumsuz etkilemektedir. Bu çalışmanın amacı diyabet ve sarkopeni ilişkisinin araştırmak ve diyabetli hastalarda sarkopeni sıklık ve şiddetini etkileyen faktörlere açıklık getirmektir. Çalışmamıza Başkent Üniversitesi Ümitköy Endokrinoloji ve Metabolizma Polikliniklerine başvuran denekler dâhil edildi. Çalışmaya katılmayı kabul eden hastaların; değişkenleri diyabeti olan bir vaka grubunda ve olmayan bir kontrol grubunda karşılaştırıldı. İstatistiksel analizlerde; iki grup karşılaştırmasında Student T Testi ve Mann-Whitney U Testi, ikiden çok grubun karşılaştırılmasında Kruskal-Wallis Testi kullanılmıştır. Kategorik değişkenlerde Pearson Ki-Kare Testi ve Fisher Exact Testi veya Yates Testi kullanılmıştır. Vaka grubuna 66 (%50,8) ve kontrol grubuna 64 denek (%49,2) alındı. Deneklerin %16,2’sinde (n=21) sarkopeni saptandı. Sarkopeni şiddetine göre deneklerin %3,9’u (n=5) sarkopenik ve %12,3’ü (n=16) şiddetli sarkopenikti. Bunların %24,2’si (n=16) vaka, %7,8’i (n=5) kontrol grubundaydı ve diyabetin sarkopeni sıklığını anlamlı olarak artırdığı görülmektedir. Yaş ortalaması vaka grubunda, kadın cinsiyet oranı kontrol grubunda yüksek saptanmıştır. Diğer sosyodemografik özellikler yönünden vaka ve kontrol grubu birbirine benzer özellikte saptanmıştır. Analizlerde diyabet yaşı, diyabet komplikasyonları ve glisemik seviye ile sarkopeni arasında anlamlı bir ilişki saptanamamıştır. Deneklerin vücut kompozisyon ve antropometrik ölçümlerine bakıldığında vaka grubundaki deneklerin daha yüksek kilo, VKİ ve yağ kitlesi miktarına ve daha geniş bel çevresi, baldır çevresi ve üst kol çevresi ölçülerine sahip oldukları saptanmıştır. Yaşam kalitesinin daha da bozulmaması için diyabet ve sarkopeni açısından taramalar yapılmalı ve gereken önlem ve tedaviler uygulanmalıdır. The increase in the elderly population and prevalence of diabetes result in a rapid increase in the number of elderly diabetic patients. The prevalence of sarcopenia is higher in diabetics than normal population, and it negatively affects quality of life. Aim of this study is to investigate the relationship between diabetes and sarcopenia and to clarify the factors affecting the frequency and severity of sarcopenia in diabetic patients. Subjects who applied to Başkent University outpatient clinics were included. Variables of patients who agreed to participate were compared in a diabetic case group and a non-diabetic control group. Student T Test and Mann-Whitney U Test were used for comparison of two groups, and Kruskal-Wallis Test for more than two groups. Pearson Chi-Square Test and Fisher Exact Test or Yates Test were used for categorical variables. The case group contained 66 (50.8%) subjects and 64 subjects (49.2%) in the control group. Sarcopenia was detected in 16.2% (n=21) of subjects. Of the subjects 3.9% (n=5) were sarcopenic and 12.3% (n=16) were severe sarcopenic. Of these, 24.2% (n=16) were in the case group and 7.8% (n=5) were in the control group, and it seems that diabetes significantly increases the frequency of sarcopenia. The mean age was higher in the case group and the female sex ratio was higher in the control group. In terms of other sociodemographic characteristics, the case and control groups were found to be similar. No significant relationship was found between the age of diabetes, diabetic complications, glycemic level and sarcopenia. It was determined that the subjects in the case group had higher weight, BMI and fat mass, larger waist circumference, calf circumference and upper arm circumference. In order not to deteriorate the quality of life, screening for diabetes and sarcopenia should be performed and necessary precautions and treatments should be applied.Item 65 yaş üstü sepsis ve septik şok hastalarında acil serviste ilk bakılan platelet lenfosit oranı ve laktat düzeyinin mortalite üzerine etkisi(Başkent Üniversitesi Tıp Fakültesi, 2017) Bıyıklı, Ebru; Kayıpmaz, Afşin EmreBaşkent Üniversitesi Ankara Hastanesi Acil Servis’ine 1 Ağustos 2014 ile 1 Ağustos 2016 tarihleri arasındaki 2 yıllık süreçte başvuran 65 yaş üzerindeki sepsis ve septik şok tanısı almış hastaların demografik özelliklerini, komorbit hastalıklarını, başvuru anındaki hemodinamik parametrelerini, acil servisteki ilk tedavi ihtiyaçlarını (sıvı, vazopressör, kan transfüzyonu, steroid ve antibiyotik gibi), mekanik ventilasyon, kardiyopulmoner resüsitasyon uygulamalarını hasta bilgi yönetim sistemi ve hasta dosyaları arşivinden elde ettik. 30 günlük mortaliteyle ilgili bilgileri ise Merkezi Nüfus İdare Sistemi (MERNİS) aracılığıyla edindik. Mortalite olan ve olmayan gruplar arasında normal dağılan verileri bağımsız iki örnek t-testi ile değerlendirdik. Normal dağılmayan verilerin karşılaştırılmasında ise Mann-Whitney U testini kullandık. Hastaların mortalite durumlarına göre qSOFA skorlarını Chi-square testiyle değerlendirdik. Mortalite üzerine bağımsız faktörleri değerlendirmek için lojistik regresyon analizi yaptık. p<0,05 değerini istatistiksel olarak anlamlı kabul ettik. Otuz gün içerisinde mortalite gözlenen ve gözlenmeyen gruplar arasında sistolik ve diastolik kan basıncı (sırasıyla p=0,045 ve p=0,002), Glaskow Koma Skalası puanı (p<0,001) ve kan üre azotu (p<0,001) yönünden anlamlı fark saptadık. Solunum sayısı (p=0,503), ateş (p=0,588), pulse oksijen saturasyonu (p=0,172), kreatinin (p=0,082), hemoglobin (p=0,541), ortalama platelet hacmi (p=0,593), lenfosit (p=0,478), PLR (p=0,821) ve laktat düzeyi (p=0,120) yönünden ise anlamlı fark saptamadık. Çalışmamızda iki grup arasında quick-Sepsis related Organ Failure Assessment (qSOFA) skorları yönünden anlamlı farklılık mevcuttu (p<0,001). Mortalite ve qSOFA arasında ise pozitif yönde korelasyon saptadık (Pearson korelasyon katsayısı 0,321). Bununla birlikte lojistik regresyon analizinde qSOFA’nın, mortalitenin bağımsız bir belirteci olmadığını tespit ettik. Sonuç olarak PLR’nin mortaliteyi öngörme yönünden klinisyene katkısını göstermeye ilişkin başka çalışmalara da ihtiyaç olduğu görüşündeyiz. Çalışmamızda mortalite gözlenen gruptaki ilk bakılan laktat düzeyleri gözlenmeyen gruba göre yüksekti ancak istatistiksel olarak anlamlı farklı değildi. Konuyla ilgili önceki çalışmalar da göz önünde bulundurulduğunda hastaların seri laktat ölçümlerinin başlangıçta bakılan tek laktat düzeyine göre klinisyene mortaliteyi öngördürme yönünde daha fazla yarar sağlayacağı inancındayız. Sepsis is a disease that can be mortal and costly to treat. The disease is especially common among elderly patients. In this study, we investigated the role of platelet-lymphocyte ratio and lactate levels measured in the emergency department for predicting the mortality from sepsis in patients older than 65 years. We enrolled 131 patients who were older than 65 and diagnosed with sepsis and septic shock in the emergency department of Baskent University Ankara Hospital between 1 August 2014 and 1 August 2016. We used the patient information management system and patient files archive information to obtain information about these patients’ demographic information, comorbid diseases, admission hemodynamic parameters, emergency department interventions (e.g., fluid replacement, vasopressor administration, blood transfusion, steroid use, and antibiotherapy), mechanical ventilation status, and cardiopulmoner resuscitation needs. We also obtained information about their 30 days’ mortality from the Central Demographics Management System. We detected a statistically significant difference between systolic and diastolic blood pressures (p = 0.045 and p = 0.002, respectively), Glasgow Coma Scale (p < 0.001), and blood urea nitrogen (p < 0.001) of the groups with and without mortality by 30 days. Respiration rate (p = 0.503), fever (p = 0.588), pulse oxygen saturation (p = 0.172), creatinine (p = 0.082), hemoglobin (p = 0.541), mean platelet volume (p = 0.593), lymphocyte (p = 0.478), platelet-lymphocyte ratio (PLR) (p = 0.821), and lactate levels (p = 0.120) were not statistically significant. We also revealed a statistically significant difference (p = 0.001) between the two groups with respect to the quick Sepsis Related Organ Failure Assessment (qSOFA) scores. We detected a positive correlation between the mortality and qSOFA (r=0.321, p<0.05). However, qSOFA was not an independent predictor of mortality in logistic regression analysis. In conclusion, we suggest that further studies of PLR are required to predict mortality in this patient population. Although lactate levels were higher in the mortality group, the difference was not significantly different. Under the light of data from previous studies, we suggest that continuous monitoring of lactate levels, as compared to an initial single measurement of lactate level, would provide clinicians with more relevant information about short term mortality.
