Öğe Abdominal aort anevrizması olan üç olgunun spiral bt anjiografisi(İnönü Üniversitesi Tıp Fakültesi Dergisi, 1997) Kutlu, Ramazan; Saraç, Kaya; Baysal, Tamer; Türköz, Rıza; Gülcüler, Metin; Gülcan, ÖnerAbdominal aort anevrizması operasyonlarının planlanmasında, cerrahi öncesi komşu vasküler yapılarla ilişkisinin belirlenmesi önemlidir. Bu yazıda abdominal aort anevrizması tespit edilen üç olgunun, cerrahi öncesi spiral bilgisayarlı tomografik anjiografi (SBTA) ile elde edilen görüntülerini ve SBTA’nın bu tip olgulardaki değerini irdeledik. SBTA'nın abdominal aort anevrizmalarında, anevrizmaların teşhisinden öte lokalizasyon ve diğer damarlarla ilişkisini saptamada oldukça önemli olduğunu düşünmekteyiz.Öğe Acute renal failure caused by blunt trauma in a kidney transplant recipient(Medicine Science | International Medical Journal, 2016) Ünal, Bülent; Kayabaş, Üner; Taşkapan, Hülya; Pişkin, Turgut; Baysal, Tamer; Kayhan, BaşakInjuries in renal graft are mostly caused by blunt trauma to the abdomen in any time after transplantation. The response to a trauma depends on the balance between inflammatory and antiinflammatory mediators. Trauma associated renal failure can be confused with acute humoral/cellular rejection in an allograft recipient. Delay in diagnosis and appropriate treatment can cause loss of graft in those patients. A 27-year-old male patient underwent renal transplantation because of unidentified end-stage renal failure. He was admitted to emergency department with abdominal pain on graft region, hematuria and oliguria. He informed that he fell down on his bottom from tabouret in the bath before onset of the complaints. After observing hematoma in renal pelvis of the transplanted kidney by urinary ultrasonography, an ureteral double J stent was applied. The serum creatinine level continuously increased, anuria was observed and creatinine level rose to 7.9 mg/dL. The patient was treated with pulsed doses of methylprednisolone, anti-thymocyte globulin because of acute allograft rejection with preliminary diagnosis. But both radiological findings of renal allograft and the performed immunological tests excluded the diagnosis of renal acute allograft rejection and confirmed the renal kidney failure due to post-traumatic blood clots in the renal pelvis and ureter of the allograft. Then he was discharged with functional graft through applied medical interventions.The application of basic immunophenotyping protocols together with clinical assessment may help to distinguish rejection from the other situations in renal transplant recipient with acute renal failure following blunt trauma.Öğe Ankilozan spondilitli hastalarda yaş ve cinsiyete göre düzeltilmiş göğüs ekspansiyonunun klinik pratikte kullanımı(Türkiye Fiziksel Tıp ve Rehabilitasyon Dergisi, 2011) Durmuş, Bekir; Altay, Zuhal; Baysal, Özlem; Ersoy, Yüksel; Hacıevliyagil, Süleyman Savaş; Baysal, Tamer; Aytemur, Zeynep Ayfer; Doğan, ErdalÖz: Amaç: Bu çalışmanın amacı; ankilozan spondilit (AS)’li hastalarda yaş ve cinsiyete göre düzeltilmiş göğüs ekspansiyonunun klinik pratikte kullanı mının uygun olup olmadığını ve göğüs ekspansiyonunun pulmoner fonk siyonlar ve hastalık şiddeti ile ilişkisini araştırmaktır. Gereç ve Yöntem: Çalışmaya 82 AS’li hasta ve 42 sağlıklı gönüllü alındı. Hastalar, yaş, cinsiyet ve düzeltilmiş göğüs ekspansiyonuna göre; göğüs ekspansiyonu kısıtlanmış ve kısıtlanmamış olmak üzere iki gruba ayrıldı. Hastalar, klinik parametrelere ek olarak, Bath AS Disease Activity Index (BASDAI), Bath AS Functional Index (BASFI) ve Bath AS Metrology Index (BASMI) ile değerlendirildi. Bulgular: Zorlu vital kapasite ve 1. saniyedeki zorlu ekspiratuar hacim; göğüs ekspansiyonu kısıtlanmış hastalarda, kısıtlanmamış hastalar ve kont rol grubuna göre anlamlı derecede azalmış bulundu. Ağrı, BASFI ve BASMI skorları, göğüs ekspansiyonu kısıtlanmış grupta istatistiksel olarak anlamlı düzeyde yüksekti. Göğüs ekspansiyonu, klinik parametreler ve solunum fonksiyon testleri ile anlamlı derecede korele idi. Sonuç: AS’li hastalarda yaş ve cinsiyete göre düzeltilmiş göğüs ekspansi yonunun klinik pratikte kullanılmasının daha uygun olduğu ve göğüs eks pansiyonunun pulmoner fonksiyonlar ve hastalık şiddeti ile ilişkili olduğu kanısına varıldı.

Başlık (İngilizce): Clinical use of chest expansion corrected for age and sex in patients with ankylosing spondylitisÖğe Atlanto odontoid osteoarthritis in rheumatoid arthritis dynamic CT findings(Clin Rheumatol, 2004) Baysal, Özlem; Baysal, Tamer; Sığırcı, Ahmet; Ersoy, Yüksel; Altay, ZuhalWe analyzed the CT appearances of degenerative change in the atlanto-odontoid joint (AOJ) in patients with rheumatoid arthritis (RA) and evaluated the effect of these changes on atlanto-axial joint (AAJ) rotation by dynamic CT. This revealed that 9 patients (24%) treated with methotrexate had degenerative features in the AOJ. The ratio of AAJ rotation to the total rotation of the cervical spine was significantly higher in normal subjects (54±3%) than in patients (38±12%). The degree of AAJ rotation was significantly lower in the patient group with degenerative features in the AOJ (20.9±8.4) than in patients without degenerative features (28.5±7.4). RA patients with a history of longstanding disease and treatment with antirheumatic drugs may develop AO OA. Although secondary OA was described as healing phenomena in the joints of RA patients, it can limit rotation in the AAJ and cause suboccipital neck pain. A regular check-up of the AAJ and AOJ by means of dynamic CT in all RA patients is proposed to avoid possible antirheumatic drug complications.Öğe Brain metabolite changes on proton magnetic resonance spectroscopy in children with poorly controlled type 1 diabetes mellitus(Neuroradiology, 2005) Saraç, Kaya; Akıncı, Ayşehan; Alkan, Alpay; Aslan, Mehmet; Baysal, Tamer; Özcan, AbdulcemalAbstract The metabolite changes in the brains of children with poorly controlled type 1 diabetes mellitus (DM) were investigated by proton magnetic resonance spectroscopy (MRS). A total of 30 subjects and 14 age-matched healthy volunteers underwent single-voxel MRS (TE: 136). The duration of disease, medication, presence of hypoglycaemia episodes and the level of haemoglobin A1C (HbA1C) in the patients were noted. Voxels were placed in the pons, left basal ganglion (LBG) and left posterior parietal white matter (PPWM). N-acetylaspartate (NAA)/creatinine (Cr) and choline (Cho)/Cr ratios were calculated. The average HbA1c level was 11.9±3.4 (8.2–19.4). The average number of keto-acidosis episodes was 1.9±2.2 (0–9) and the average number of daily insulin injections was 2.8±0.97 (2–4). MRS revealed lower NAA/Cr and Cho/Cr ratios in the pons and lower NAA/Cr ratio in the PPWM of patients with DM than in control subjects. No significant correlation was observed between the number of hypoglycaemia episodes and metabolite ratios. Metabolic abnormalities have been observed by MRS in the brain of poorly controlled type 1 DM children. These metabolic changes, in particular in the pons region, include a decrease in NAA, indicating neuronal loss or functional impairment, and likely explanations for a decrease in Cho may be dynamic changes in membrane lipids and/or decreased membrane turnover.Öğe Brain metabolite changes on proton magnetic resonance spectroscopy in children with poorly controlled type1 diabetes mellitus(NEURORADIOLOGY, 2005) Saraç, Kaya; Akıncı, Ayşehan; Alkan, Alpay; Aslan, Mehmet; Baysal, Tamer; Özcan, AbdulcemalThe metabolite changes in the brains of children with poorly controlled type 1 diabetes mellitus (DM) were investigated by proton magnetic resonance spectroscopy (MRS).

Retained sponge in the breast is extremely rare in the literature. The radiologic identification of gossypiboma is difficult because of their variable appearance. But when typical radiologic appearances are present in a patient with previous breast surgery, pre-operative diagnosis of a retained surgical sponge may prevent fatal complications. We present Aunt Minnie'' findings of gossypiboma in a patient with previous breast surgery including ultrasound (US), mammogram and computed tomography (CT). (C) 2005 The College of Radiographers.

[Turgut Özal Tıp Merkezi Dergisi 1998;5(l):68-70]Öğe BT eşliğinde yapılan toraks ince iğne aspirasyon biyopsilerinde erken sitolojik değerlendirmenin yeri(Türk Tanısal ve Girişimsel Radyoloji Dergisi, 2002) Baysal, Tamer; Mızrak, Bülent; Soysal, Ömer; Sığırcı, Ahmet; Kutlu, RamazanToraks patolojilerinde bilgisayarlı tomografi eşliğinde yapılan ince iğne aspirasyon biyopsilerinde hasta başında yapılan erken sitolojik değerlendirmenin tanıya katkısını araştırmaktır. GEREÇ VE YÖNTEM Bronkoskopik biyopsi yöntemi ile tanı konulamayan 65 olguda bilgisayarlı tomografi eşliğinde ince iğne aspirasyon biyopsisi yapıldı. Sitoloğun hasta başında biyopsi materyalini değerlendirmesi erken sitolojik değerlendirme, patoloji bölümünde tüm lamların değerlendirilmesi son sitolojik değerlendirme olarak kabul edildi. Sitolojik tanılar ile histopatolojik bulgular karşılaştırıldı. BULGULAR Doğru tanı konan 63 olgunun sitolojik değerlendirmesine göre 41 olguda malign, 22 olguda benign patoloji saptandı. Sitolojik olarak benign patoloji tanısı alan bir olguda histopatolojik sonuç malign çıktı. Erken ve son sitolojik tanılar arasında malign lezyonlarda %100, benign olanlarda % 89 uyum vardı. Malign lezyonlarda sitolojik ve histopatolojik tanılar %97.6 uyumlu idi. Biyopsi tekrar oranı %13.8 ve pnömotoraks görülme oranı %7.7 idi. SONUÇ Erken sitolojik değerlendirme toraks ince iğne aspirasyon biyopsilerinde tanıya erken ve yüksek doğ- ruluk oranı ile ulaşılmasını sağlayan, biyopsi tekrarını ve dolayısı ile komplikasyon oranını en aza indiren bir multidisipliner çalışmadır. Özellikle sitolojik incelemenin spesifisitesinin düşük olduğu benign lezyonlarda sitoloğun radyolojik olarak lezyon morfolojisi hakkında fikir edinmesi, sitolojik yoruma olumlu katkıda bulunmaktadır.Öğe Büyük kalsifiye substernal benign guatra bağlı üst solunum yolu obstrüksiyonu(İnönü Üniversitesi Tıp Fakültesi Dergisi, 1996) Hasanoğlu, Adnan; Baysal, Tamer; Bülbüloğlu, Ertan; Yıldırım, ZekiTiroid bezinde, solunum yolu obstrüksiyonu oluşturacak kalsifiye, büyük benign nodüller sık görülmemektedir. 53 yaşındaki kadın hasta, büyük kalsifiye benign guatra bağlı üst hava yolu obstrüksiyonu, stridor ve dispne ile bize geldi.

Metarials and Methods: Eighty-two patients with AS and 42 healthy controls were included in the study. The patients were divided into two groups according to chest expansion corrected by age and sex: restricted and non-restricted groups. Additional to the clinical evaluation, the Bath AS Disease Activity Index (BASDAI), Bath AS Functional Index (BASFI), and Bath AS Metrology Index (BASMI) were used to evaluate disease activity functional impairment, and mobility respectively. Results: Forced vital capacity and forced expiratory volume in the first second were significantly decreased in the restricted group when compared to the non-restricted and control groups. Pain, BASFI, and BASMI scores were significantly higher in the restricted group compared to the non-restricted one. Chest expansion was significantly correlated with clinical parameters and pulmonary function tests. Conclusion: Chest expansion measurement corrected for age and sex is appropriate for clinical practice and chest expansion is associated with pulmonary functions and disease severity.

A 36-year-old diabetic woman referred to our clinic with severe pain in the left anteromedial thigh. She had a 15-year history of Type 2 diabetes mellitus (DM). She was complicated by diabetic nephropathy and requiring hemodialysis. She had first noticed pain and swelling in her left thigh after a minimal trauma for 2 days prior to presentation. Clinical and laboratory evaluation, and muscle biopsy revealed the diagnosis of muscle infarctions. She did no respond to the conservative therapy. Pain and swelling in her thigh worsened progressively. She underwent surgical debridment and then, her clinical status improved. We describe the characteristic clinical and pathologic findings and the course of the illness with emphasis on the importance of recognition of the syndrome so that unnecessary investigation and overzealous therapy can be avoided.Öğe Diffusion-weighted magnetic resonance imaging in differentiation of postobstructive consolidation from central lung carcinoma(Elsevier Science Inc, 2009) Baysal, Tamer; Mutlu, Deniz Yakar; Yologlu, SaimPurpose: To prospectively evaluate diffusion-weighted (DW) magnetic resonance (MR) imaging for differentiation of postobstructive consolidation from centrally located lung carcinomas by using apparent diffusion coefficients (ADCs). Materials and Methods: An institutional review board approved this study; informed consent was obtained from patients. Forty-nine consecutive patients (3 women, 46 men; mean age, 63.6 years; age range, 42-85 years) with lung carcinoma underwent DW MR imaging. Forty patients had central and nine patients had peripheral lung carcinomas. ADC of each lung carcinoma was calculated from DW MR images obtained with two different h Values (0, 1000 s/mm(2)). In the final Study group including 27 patients with central lung carcinoma accompanying distal lung consolidation (mean age, 67.2 years, 3 women, 24 men), ADCs Of lung carcinomas were statistically compared among cytologic/histologic types and accompanying postobstructive consolidations. Unpaired t test was used for measurable variables with normal distribution, and Kruskal-Wallis variance analysis and Mann-Whitney U tests were used for the Measurable variables without normal distribution. Results: There was no significant difference between mean ADC values of all types of carcinomas (P=.302) and also between mean ADC values of central (1.91 +/- 0.7 x 10(-3) mm(2)/s) and peripheral carcinomas (1.58 +/- 0.6 x 10(-3) mm(2)/s) (P=.224). The mean ADC value for the masses Of Central lung carcinoma with postobstructive consolidations was 1.83 +/- 0.75 x 10(-3) mm(2)/s, and for consolidation was 2.50 +/- 0.76 x 10(-3) mm(2)/s. ADC of central carcinoma masses was significantly lower than that of postobstructive consolidations (P=.003). Conclusions: A DC values of central lung I I Ling carcinoma masses appear to be lower than accompanying postobstructive consolidations. A DC values Could be considered useful as a differentiating parameter among central lung carcinomas and accompanying postobstructive consolidations. (C) 2009 Elsevier Inc.

The purpose of this study was to evaluate the Doppler sonographic blood-flow parameters and spectral patterns in the inferior mesenteric artery (IMA) and superior mesenteric artery (SMA) in patients with active and inactive (remission-phase) ulcerative colitis (UC). Methods. The IMAs and SMAs of 25 patients with active-phase UC (group 1), 19 patients with remissionphase UC (group 2), and 22 healthy, asymptomatic subjects (control group) were evaluated by duplex Doppler sonography. The 25 patients in group 1 were categorized into 2 subgroups on the basis of the extent of disease as determined by double-contrast barium enema x-ray study and colonoscopy. The first subgroup (group 1a) consisted of 11 patients with active involvement of the left colon from the rectum to the splenic flexure. The second subgroup (group 1b) consisted of 14 patients with active involvement of the entire colon. The peak systolic velocity (PSV), enddiastolic velocity (EDV), mean velocity (Vmean), resistance index (RI), and pulsatility index (PI) were determined from the Doppler spectral analysis. The inner diameter and cross-sectional area of the IMA and SMA were measured, and the blood-flow volume was calculated. The results were compared between the patient groups and control subjects. Results. In the IMA, the mean blood-flow volume, mean PSV, mean EDV, and Vmean were significantly higher, the mean PI was significantly lower, and the mean diameter and the mean cross-sectional area were significantly larger in group 1 than in group 2 or in the control group (p < 0.001). The mean PSV and the Vmean of the IMA were significantly higher in group 1a than in group 1b (p < 0.05). The mean blood-flow parameters in the SMA were not significantly different between groups 1 and 2 or between either group 1 or group 2 and the control subjects. The mean EDV in the SMA was significantly higher and the mean PI and the mean RI were significantly lower in group 1b than in group 1a (p < 0.01). Conclusions. Duplex Doppler sonography of the IMA and SMA can be used to evaluate inflammatory disease of the large bowel, to assess disease extent, and to document response to therapy.Öğe Doppler waveforms and blood flow parameters of the superior and inferior mesenteric arteries in patients having behçet disease with and without gastrointestinal symptoms(J Ultrasound Med, 2003) Sığırcı, Ahmet; Şenol, Mustafa; Aydın, Erdinç; Kutlu, Ramazan; Alkan, Alpay; Altınok, M. Tayfun; Yoloğlu, Saim; Baysal, Tamer; Saraç, KayaObjective. To evaluate hemodynamic changes in mesenteric arteries in patients with Behçet disease with and without gastrointestinal symptoms. Methods. Doppler sonography of mesenteric arteries was performed in 25 symptomatic and 15 asymptomatic patients having Behçet disease and in 25 healthy control subjects. The peak systolic, minimal, and mean velocities, resistive and pulsatility indexes, inner diameter, cross-sectional area, and blood flow volume of mesenteric arteries were evaluated. The results were compared between patient groups and controls. Results. The mesenteric artery flow was significantly greater in patients in the symptomatic group than in those in the asymptomatic group or in controls. In the superior mesenteric artery, mean velocity and mean blood flow volume (0.35 ± 0.18 m/s and 711 ± 404 mL/min, respectively; P < .0001) in the symptomatic group were significantly higher than in the asymptomatic group (0.16 ± 0.07 m/s and 305 ± 168 mL/min, respectively) or in controls (0.15 ± 0.07 m/s and 290 ± 123 mL/min, respectively). The mean peak systolic velocity (1.23 ± 0.47 m/s; P < .005) in the symptomatic group was significantly higher than in controls (0.93 ± 0.23 m/s). In the inferior mesenteric artery, mean velocity and mean blood flow volume (0.25 ± 0.10 m/s and 139 ± 79 mL/min) in the symptomatic group were significantly higher than in the asymptomatic group (0.16 ± 0.07 m/s; P < .006; and 78 ± 26 mL/min; P < .007) or in controls (0.17 ± 0.07 m/s; P < .003; 83 ± 48 mL/min; P < .004). Conclusions. In this study, symptomatic patients with gastrointestinal Behçet disease were associated with a significant increase in mesenteric artery flow that could be evaluated easily on spectral patterns of arteries during Doppler sonography. The Doppler sonographic findings also revealed that intestinal involvement in patients with Behçet disease without gastrointestinal symptoms is not significantly different from that of healthy controls.
