Several studies have reported several platelet abnormalities in patients with sub-clinical or overt thyroid dysfunctions. The primary mechanism that affects the hemostatic balance is excess or deficiency of thyroid hormones. The different ways of thyroid gland to the platelet function are not yet clearly understood. The relationship between in the thyroid gland and platelet activation without thyroid hormones has not been studied yet. The aim of our study is to determine the platelet function in euthyroid patients undergoing thyroidectomy in females. The study group includes 52 female euthyroid patients undergoing thyroidectomy. The control group consisted with 21 healthy euthyroid female. Platelet count (PC), platelet mass (PM), mean platelet volume (MPV), and platelet distribution width (PDW) were measured. PM was calculated by multiplying MPV and PLT. MPV (8.4 ± 1.3 versus 7.9 ± 0.8) and PDW (17.8 ± 1 versus 17.6 ± 0.8) values were similar between the two groups. Thyroid gland does not directly affect platelet activation. Accordingly, platelet abnormalities of thyroid disease can be considered to be independent of the underlying thyroid tissue. This finding suggests that association between thyroid diseases and platelet function is dependent on the status of thyroid hormones.

Aim: The aim of our study is to determine the microbiology of the external auditory canal and nose in uremic patients on chronic dialysis. Methods: All patients undergoing regular hemodialysis for at least 3 months were included in this study. The nasal and external auditory canal swabs were collected from 83 haemodialysed patients. Results: From 83 patients (37 females, 46 males) nasal and external auditory canal cultures were obtained. Mean duration on dialysis was 41.75 ± 45 months and mean age of patients was 61 ± 13 years. Microflora in the nasal cavities (70/80, 87.5%) and external auditory canal (48/59, 81.3%) were similar in all culture positive patients (coagulase-negative staphylococci). Coexistence of coagulase- negative staphylococci and diphteroids was detected in 20 patients' (25.0%) nasal vestibule and in eight patients' (13.5%) external auditory canal. Conclusion: Microflora in the nasal cavities and external auditory canal were similar in chronic renal patients. External auditory canal microflora was not associated with history of diabetes mellitus, hepatitis status and starting date of hemodialysis in our study.

Introduction: Cardiovascular disease is the leading cause of morbidity and mortality in hemodialysis patients. Therefore, evaluation and prevention of cardiovascular diseases in end-stage renal disease (ESRD) patients are very important. The plasma level of omentin was found to be associated with different conditions such as insulin resistance. It is one of the novel adipokines synthesized mainly in the visceral adipose tissue. In this study, we aimed to investigate the level of omentin in patients with ESRD receiving hemodialysis. Methods: The study population consisted of 59 adult chronic hemodialysis patients (30 women and 29 men) and age-matched control subjects were selected from apparently healthy subjects (28 participants; 14 women and 14 men). Blood samples were obtained before the dialysis session. Omentin concentrations were determined by using enzyme-linked immunosorbent assay. Results: Plasma levels of omentin were found to be markedly higher in ESRD patients (606.6 ± 313.0 ng/ml) than in the control group (357.5 ± 147.4 ng/ml; p < 0.0001). Also, serum omentin levels were found to be correlated with creatinine (r = 0.333, p = 0.002). Conclusions: Omentin levels were found to be elevated in patients with ESRD receiving hemodialysis. To the best of our knowledge, this is the first clinical study that demonstrated the association between omentin and ESRD. Copyright © 2012 S. Karger AG, Basel.

Introduction: In this study, we aimed to investigate the relationship between glycated haemoglobin (HbA1c) levels and the severity of coronary artery disease (CAD) in < 40 years old patients. Material and methods: The study population consisted of 211 premature coronary atherosclerotic patients (pCAP) (aged 36.4 ± 2.5 years) and 160 control subjects (36.4 ± 2.4 years). The severity of CAD was evaluated by the Gensini scoring system. HbA1c levels and the other basic biochemical parameters were analysed, and relations with severity of CAD were evaluated. Results: There were statistically significant differences in serum HbA 1c levels between the two groups (pCAP = 6.1 ± 1.8%, control = 4.7 ± 1.2%, p < 0.001). HbA1c levels significantly positively correlated with the Gensini score in pCAP (r = 0.662, p < 0.001). In linear multivariate regression analysis (including age, sex, HbA 1c, smoking, diabetes mellitus and hypertension as dependent parameters), only HbA1c was found to be an independent risk factor for the presence of severe CAD (Beta = 0.374, p < 0.001). In ROC curve analysis, the optimal cut-off value of HbA1c to predict severe CAD was 6.52%, with 74.4% sensitivity and 75.1% specificity (area under the curve 0.781, 95% confidence interval 0.661 to 0.901, p < 0.001). Conclusions: HbA1c levels were found to be correlated with the Gensini score in pCAP with and without diabetes. In this respect, glucose metabolism abnormalities, indicated by HbA1c, may play an important role in premature CAD.

Pancreatic ischemia is an uncommon cause of acute pancreatitis. Ischemia with resultant pancreatitis has been reported in vasculitis, atheroembolism, intraoperative hypotension, survivors of cardiac arrest and hemorrhagic shock. Ischemic acute pancreatitis is difficult to recognize clinically. In this report we present a 63 year old woman with painless ischemic pancreatitis following urosepsis. We suggest that if a critically ill patient is hypotensive for more than 24-48 hours, amylase levels must be monitored to establish ischemic acute pancreatitis (AP) even if the patient remains asymptomatic. © 2013 OMU.
