Objective: Cardiorenal syndrome (CRS) describes a dysregulation of the heart and kidneys affecting each other. Recently hemodialysis treatments were used more frequently. Aim was to analyze the effects of conventional diuretic and UF treatments. Material and Methods: Thirty-four Type 4 CRS diagnosed patients were included. Baseline characteristics were recorded. Echocardiography measured at the admission and at the end of the treatment. Results: The mean age 67.4±9.3 (51-93) years and follow-up period were 15.9±11.5 months. The patients were grouped as diuretic group, n=12 and UF group, n=22. At the beginning mitral valve A wave, bl . . .ood urea nitrogen and creatinine values were higher in the UF group while creatinine values were higher in the UF group compared to diuretic group at the end of the study. Although basal ejection fraction (EF) values were not different, it was higher in the UF group at the end of the study (42.38±12.70 % and 29±3.67 %, p 0.05). Conclusion: In Type 4 CRS, mortality and hospital admissions were not reduced by UF treatment but cardiac function assessed by EF was significantly improved suggesting this therapy to be beneficial in appropriate patients Daha fazlası Daha az

Background/Aim. Coronary artery ectasia (CAE) is considered as a variant of atherosclerosis. Tumor necrosis factor-alpha (TNF- ) and interleukin-6 (IL-6) are among the sensitive markers of systemic inflammation. The aim of this study was to evaluate the plasma levels of the cytokines; TNF- and IL-6 in CAE patients. Methods. Plasma concentrations of TNF- and IL-6 were measured in 36 patients with CAE (28 males, mean age: 58.2±12 years), and results were compared with age and sex-matched controls (n = 32) without coronary artery ectasia. TNF- and IL-6 concentrations in blood were assesed by enzyme-linked immunosorbent assay (ELISA). R . . .esults. Baseline characteristics of the two groups were similar. TNF- and IL-6 levels were significantly higher in CAE group than controls (15.6±11.2 pg/mL versus 7.8±3.7 pg/mL, Daha fazlası Daha az

Bu çalışmada kısa süreli marihuana (esrar) kullanımı sonrası oligoastenospermi ve jinekomasti belirlenen bir olgunun sunulması amaçlanmıştır. Olgu: Otuzbir yaşında erkek, yaklaşık 20 günlük sol göğüs meme başı altında kitle yakınması ile başvurdu. Kitlenin ortaya çıkmaya başlamasından önceki yaklaşık 15 gün boyunca günlük esrar kullanımı tanımlamaktaydı. Fiziki muayenede sol meme areola altında hassas olmayan, çevre dokuya fikse olmamış 50 mm'lik kitle palpe edildi. Hastanın serum östradiol düzeyi yüksek bulundu. Ayrıca; sperm sayısının azalmış ve motilitesinin kaybolmuş olduğu saptandı. Meme ultrasonografisinde; sol memede 45 x 35 . . .x 25 mm'lik kitle vardı. Belirlenen kitlenin total eksizyonu ile yapılan patolojik inceleme ile hipertrofik meme dokusuna ait fibroadipoz doku içinde duktal yapılarında kistik genişlemeler dikkati çekti. A tipi veya displazi bulgusu mevcut değildi. Hastaya bu bulgularla jinekomasti tanısı konuldu ve ek tedavi planı yapılmadı. Hasta rutin poliklinik kontrollerine çağrıldı. Bu bir yıllık dönemde esrar hiç kullanmayan hastada jinekomasti bulgusu tekrarlamadı. Medikal tedavisiz bir yıllık takipte olgunun jinekomasti açısından herhangi bir yakınması yoktu ve serum estradiol seviyesi normal bulundu. Ayrıca; kontrol sperm analizinde düzelmeye başladığı saptandı. Bu olgu, bize kısa dönem esrar kullanımı ile bile jinekomasti ve oligoastenospermi gelişebileceğini düşündürmektedir. We aimed to present a case with oligoasthenospermia and gynecomastia after short term use of marihuana (cannabis). Case: Thirty one years old male admitted with complaint of sensation of mass in his left breast for the last 20 days. He was using cannabis for 15 days before noticing the mass. At physical examination; he had a subareolar nontender mass in his left breast which was approximately 50 millimeters in diameter and without signs of fixation into surrounding tissue. The patient had elevated serum estradiole levels. Sperm analysis revealed decreased sperm count and loss of sperm motility. Breast sonography revealed a hypoechoic mass 45x35x25 millimeters in diameters in his left breast. Abdomi-nal and scrotal sonographic examinations were normal. To-tal excision of the defined mass revealed hypertrophic mam-mary glands with cystic dilatations of several ductal structure in a fibroadipose tissue. There was no sign of atypia and or dysplasia. Gynecomastia was diagnosed and no further treatment was planned. He was called for routine follow up. During the next one year, he did not use cannabis and gynecomastia did not reappear. His control serum estradiol levels were decreased to normal ranges. Moreover; control sperm analyses were also evaluated as nearly normal. This case suggests that even short term use of cannabis can lead to gynecomastia and oligoasthenospermia Daha fazlası Daha az

Makale | 2013 | Journal of Cardiology Cases8 ( 1 ) , pp.35 - 39

Dual left anterior descending coronary artery (LAD) is a rare coronary anomaly and is divided into six subgroups in the literature according to the origin and course of the short and long branches of the anomalous artery. We present two distinct cases of dual LAD which are distinguished by two branches of equal length from their counterparts in the literature. Learning objective: In our cases a novel dual LAD variant is presented with two main branches of equal length and reaches the cardiac apex. Cardiologists and cardiovascular surgeons should be aware of these variants to avoid misinterpretation of coronary angiography and intrao . . .perative complications. © 2013 Japanese College of Cardiology Daha fazlası Daha az

Makale | 2011 | Echocardiography28 ( 6 ) , pp.612 - 618

Background: Our aim was to investigate whether diastolic functions, myocardial velocities and pulmonary vein flow show diurnal variation within a 24-hour day. Method and Results: Fourty-four healthy subjects with no history of cardiovascular or systemic diseases (32 males, 12 females; mean age 34.7 ± 8.7 years, mean BMI: 25.5 ± 3.5 kg/m 2) were enrolled in this study. None of the subjects had a history, symptoms or signs of cardiovascular or systemic diseases or were taking drugs of any kind. All underwent echocardiographic examination at 7 a.m., 1 p.m., 7 p.m., and 1 a.m. M-mode systolic, diastolic velocities and pulmonary vein flo . . .w measurements were obtained. There were no differences in systolic and diastolic blood pressures and heart rate. The left atrial diameter was greater at 1 p.m. (3.80 ± 0.44; P = 0.031). The isovolumic contraction time (ICT) was found to be the shortest (41 ± 12 msn; P = 0.050), and ejection time (ET) the longest (290 ± 31 msn; P = 0.017) at the 1am measurements. The mitral myocardial performance index (MPI) was lowest during the 1 a.m. measurements (0.42 ± 0.11; P = 0.001). The systolic myocardial velocities (Sm) obtained from the septum and inferior region were significantly higher at 1 p.m. and lower at 7 a.m. (9.17 ± 1.79, 10.25 ± 2.29; 8.11 ± 1.06, 8.63 ± 1.49; P < 0.05). The late diastolic velocities obtained from the lateral, inferior and anterior regions were higher at 1 p.m. and 7 p.m. Conclusion: The left ventricular diameter and ejection fraction did not exhibit circadian variations. However, our data indicate that some parameters reflecting diastolic function, systolic myocardial velocities and MPI, as well as left atrial diameter change at different times of the day, independent of blood pressure and heart rate. © 2011, Wiley Periodicals, Inc Daha fazlası Daha az

OBJECTIVES: The aim of this study was to compare the effects of the new generation ß-blocker anti-hypertensive drugs carvedilol and nebivolol on aortic elastic properties which are important indicators of hypertension-related morbidity and mortality.METHODS: A total of 50 patients who had been diagnosed with stage 1 hypertension according to the Joint National Committee (JNC) VII criteria and who had not received any anti-hypertensive treatment were enrolled in this study. Patients were randomized to receive either 25 mg/day carvedilol (n=25) or 5 mg/day nebivolol (n=25) for 3 months at the beginning of the study. Three patients (1 . . .in the carvedilol group, 2 in the nebivolol group) who did not attend 3 month follow-up measurements were excluded from the study. The study was completed with 47 patients (25 women; mean age: 49 ± 9 years). The aortic elastic parameters such as aortic strain (AS), aortic distensibility (AD), and aortic stiffness index (ASI) were measured by echocardiography.RESULTS: Carvedilol and nebivolol provided a similar decline in both systolic and diastolic blood pressures (-12/-7 mmHg, Daha fazlası Daha az

OBJECTIVES: Studies have shown that nitric oxide (NO) may play a major role in sustaining mucosal integrity; however, NO has been also implicated in the pathogenesis of ischemia/reperfusion (I/R)-related tissue injury. We investigated the effects of L-arginine and N-nitro L-arginine methyl ester (L-NAME) on the acetylcholine-induced contractile response of ileum and the levels of malondialdehyde (MDA) and reduced glutathione (GSH). Histopathological changes were also evaluated in ileal preparations. MATERIALS AND METHODS: Male Wistar Albino rats were subjected to mesenteric ischemia (30 min) followed by reperfusion (3 hours). Four g . . .roups were designed: sham-operated control; I/R; I/R and L-arginine pretreatment; and I/R and L-NAME pretreatment. After reperfusion, ileum specimens were collected to determine the parameters mentioned above. RESULTS: Following reperfusion, a significant decrease in acetylcholine-induced contractile response, an increase in lipid peroxidation, a decrease in GSH content, and mucosal damage of the ileal preparations were observed. We showed that decreased contractility, increased lipid peroxidation, and reduced GSH content have been reversed by L-arginine but not by L-NAME. Mucosal injury was significantly lowered in the L-arginine group. CONCLUSIONS: Treatment with L-arginine exerted a protective effect in intestinal I/R injury, which was mediated in part by regulating MDA and GSH levels, consequently ameliorating impaired contractile response and mucosal injury. © 2008 Lippincott Williams & Wilkins, Inc Daha fazlası Daha az

Staphylococcus lugdunensis is an infrequent cause of infective endocarditis (IE) and usually involves native valves of the heart. It causes life-threatening events such as rupture of cardiac valve or cerebral or pulmonary embolism due to necrosis on the endocardial tissue involved by the bacteria. Antibiotic therapy without cardiac surgery or delayed cardiac surgery usually follows a fatal course in S.lugdunensis endocarditis. In this report the first case of S.lugdunensis endocarditis from Turkey was presented. A 37 years-old man was admitted to the emergency department with a 2-weeks history of fever chills and accompanying interm . . .ittent pain on the left side of the thorax. Other than recurrent folliculitis continuing for 20 years, his history was unremarkable. Echocardiography revealed vegetation on the mitral valve of the patient and vancomycin plus gentamicin were initiated with the diagnosis of IE. All blood cultures (5 sets) taken on admission and within the initial 48 hours of the antibiotic therapy yielded S.lugdunensis. According to the susceptibility test results, the antibiotic therapy was switched to ampicillin-sulbac-tam plus rifampin. Blood cultures became negative after the third day of therapy, however, cardiac failure was emerged due to rupture of mitral valve and chorda tendiniea on the 12 th day of the therapy. Cardiac surgery revealed that mitral valve and surrounding tissue of the valve were evidently necrotic and fragile, anterior leaflet of the mitral valve was covered with vegetation, posterior leaflet and chorda tendiniea were ruptured. Vegetation was removed and the destructed mitral valve was replaced with a mechanical valve. Vegetation culture remained sterile, however, antibiotics were switched to vancomycin plus rifampin due to persistent fever on the 21 st day of the therapy (9 th day of operation). Fever resolved four days after the antibiotic switch. Antibiotics were stopped on the 9 th weeks of admission and the patient was discharged. He had no problem in follow-up controls for one year. In conclusion, proper antibiotic therapy combined with early cardiac surgery seems to be the optimal therapeutic approach in IE caused by S.lugdunensis Daha fazlası Daha az

Giriş ve amaç: Standart üçlü tedavi ile Helicobacter pylori (H. pylori) eradikasyonu sağlanmayan olgularda ikinci tedavi ile eradikasyon daha zordur. H. pylori eradikasyon başarısızlıklarında uygulanacak tedavi kombinasyonları kesin belirlenmemiştir. Bu çalışmada lansoprazol, amoksisilin ve klaritromisin (LAK) ile yapılan standart üçlü tedavi ile H. pylori eradikasyonu sağlanamayan olgularda lansoprazol, ranitidin bizmut sitrat, tetrasiklin ve metronidazolden (LBTM) oluşan dörtlü tedavinin etkinliğini araştırdık. Gereç ve yöntem: Peptik ülser hastalığı veya nonülser dispepsi nedeniyle standart üçlü LAK tedavisi verilen ve H. pylori . . .eradikasyonu sağlanamayan toplam 36 olgu çalışmaya alındı. Bu olgulara lansoprazol (2x30 mg), ranitidin bizmut sitrat (2x400 mg), tetrasiklin (4x500 mg) ve metronidazolden (3x500 mg) oluşan dörtlü tedavi 14 gün verildi. Tedavinin bitiminden iki ay sonra endoskopik biyopsi ile H. pylori eradikasyonu değerlendirildi. Bulgular: Olgulardan beşi tedavi bitiminde kontrole gelmediğinden çalışma dışı bırakıldı. Dörtlü tedavi ile H. pylori eradikasyon oranı çalışmaya alınan tüm olgular değerlendirildiğinde %58.3, çalışma sonunda kontrole gelen olgular değerlendirildiğinde ise %67.7 saptandı. Sonuç: Bölgemizde standart LAK tedavisi ile H. pylori eradikasyonu sağlanamayan olgularda LBMT dörtlü tedavi kombinasyonunun başarı oranını oldukça düşük bulduk. Bu durumun ülkemizdeki metronidazol direncinin yüksek seviyelerde olması ile açıklanabileceğini düşünmekteyiz. Ülkemizde farklı bölgelerde H. pylorinin antibiyotik direnç durumunu ve tedavi başarısızlığı sebeplerini değerlendiren araştırmalara ihtiyaç vardır. Background/aim: Successful eradication of Helicobacter pylori (H. pylori) infection after failure of standard triple therapy is difficult. There are no guidelines on second-line therapies for H. pylori eradication failures. In the present study we investigated the efficacy of a 14-day quadruple regimen combining lansoprazole, ranitidine bismuth citrate (RBC), tetracycline and metronidazole as rescue treatment for Helicobacter pylori infection after failure of standard triple therapy combining lansoprazole, amoxicillin, clarithromycin (LAC). Materials and methods: A prospective study was designed consisting 36 patients infected with H. pylori and diagnosed with peptic ulcer or non-ulcer dyspepsia in whom triple therapy with LAC had failed. The patients were treated with quadruple therapy including lansoprazole, 30 mg twice daily, RBC, 400 mg twice daily, tetracycline, 500 mg four times daily, and metronidazole, 500 mg three times daily, for 14 days. Two months after completion of therapy, endoscopic biopsy evaluation was performed to confirm eradication. Results: Five cases who did not attend to the appointment were excluded from the study. With quadruple therapy, the H. pylori eradication rates were 58.3% by intention-to-treat analysis and 67.7% by per protocol analysis. Conclusion: The success rate of quadruple therapy with LBTM was found to be low in patients in whom standard triple therapy had failed in western Blacksea region. This finding may be explained by higher rates of metronidasole resistance in our country. We conclude that further studies about the drug resistance rates and explanation of reasons for treatment failure must be carried out Daha fazlası Daha az
