BackgroundTo evaluate and compare the diagnostic efficiency of serum (s) and pleural (p) levels of adenosine deaminase (ADA)-1, ADA-2, total ADA, and interferon-gamma (IFN-γ) for the differential diagnosis of pleural tuberculosis (TB).MethodsClinical and analytic data of 93 consecutive patients with pleural effusions from May 2012 to February 2013 were prospectively evaluated. The study population included 43 pleural TB, 23 malignancies, and 27 other exudates. The median and interquartile range of ADA-1, ADA-2, total ADA, and IFN-γ were evaluated according to their underlying diseases.ResultsThere were no significant differences in sADA-1 and sIFN-γ values among each group. pADA-1, pADA-2, total pADA, and pIFN-γ levels were significantly higher in patients with pleural TB than in other patients (p < 0.0001). As for pleural TB receiving operating characteristic (ROC) curves identified the following results. The best cut-off value for pADA-2 was 20.37 U/L and it yielded a sensitivity and specificity of 95.35% and 86%, respectively. Taking a cut-off value of 40.68 U/L for total pADA, the sensitivity and the specificity were found to be 88.37% and 88%, respectively. ROC curve identified 110 U/L as the best cut-off value for pμg/ml, while the sensitivity and the specificity were 74.42% and 68%, respectively. Finally, the best cut-off value for pADA-1 was 16.8 U/L and yielded a sensitivity and specificity of 69.77% and 68%, respectively.ConclusionsTo distinguish pleural TB, pleural levels of ADA-2 have the highest sensitivity among the different diagnostic parameters and may find a place as routine investigation for early detection of TB in the future.

Objective: The aim of this study is to investigate the effect of low-energy shock wave therapy (LESWT) on angiogenesis factors at penile tissue in a diabetic rat model. Material and methods:A total of 30 male Sprague-Dawley rats which were allocated into three equal groups were included study. Group 1 (control group) included 10 male rats which did not receive any treatment were randomly chosen to serve as normal control. The remaining rats were injected intraperitoneally with 60 mg/kg of streptozotocin (STZ) to induce diabetes. Diabetic rats were divided into two equal group which constituted diabetic control, and LESWT treatment (DM+LESWT) group. Each rat in the DM+LESWT group received L-ESWT therapy. Endothelial nitric oxide synthase (eNOS) and vascular endothelial growth factor (VEGF) mRNA expression levels of penile tissue were evaluated. Results:Following STZ dosing eNOS level dropped in the diabetic control group relative to the control group. Statistically significant increase in eNOS levels were seen in the LESWT+DM group. Similarly, in the diabetic control group STZ treatment decreased VEGF levels, while in the LESWT+DM group VEGF nearly approached to baseline levels. However variations in VEGF levels were not statistically significant. Conclusion:Mechanism action of ESWT in the penile tissue seems to involve angiogenic factors.
