Dural metastasis from prostatic adenocarcinoma mimicking meningioma : report of a case with unilateral loss of vision

We report a case of PCa (prostatic adenocarcinoma) with transdural metastasis which radiologically simulated a meningioma. During the course of the disease, the patient complained of progressive unilateral loss of vision as the first presentation of intracranial, extra-axial metastasis

Can Hounsfield unit values of the cortex and papillae determined by computed tomography demonstrate the possibility of kidney stone formation?

WOS: 000304590300014PubMed: 21497033Purpose: This study is aimed at measuring HU values of the renal cortex and papillae in patients with nephrolithiasis and demonstrating renal changes associated with nephrolithiasis. Materials and methods: Measurements were performed with regard to HU values of the cortex and papillae of 82 patients with unilateral nephrolithiasis and 81 patients in the control group at the level of the upper pole, middle region and lower pole of both kidneys. Results: When the HU values obtained from the upper pole, middle region and lower pole of the kidney with calculi and unaffected kidney in patients with nephrolithiasis were compared with those for the control group, the difference among the groups were found to be significant (p < 0.001). A comparison of the cortex and papillae densities of the affected and unaffected kidneys in patients with unilateral nephrolithiasis were compared with regard to the upper pole and middle region, no statistically significant difference was observed with regard to both the cortex and papillae densities of the upper pole, middle region. However, in those patients with calculi in the lower pole, the region with calculi has a higher papillae density as compared to the unaffected region. Conclusion: Both kidneys in patients with calculi have a comparatively high renal cortex and papillae densities. In the future, this information may be useful in predicting which patients may develop nephrolithiasis. (C) 2011 Elsevier Ireland Ltd. All rights reserved

Evaluation of effects of Extracorporeal Shock Wave Lithotripsy on renal vasculature with Doppler ultrasonography

WOS: 000334024100004PubMed: 24286090In this prospective study, we aimed to demonstrate the effects of Extracorporeal Shock Wave Lithotripsy (ESWL) on renal blood flow in patients treated for renal/ureteral stones. Material and methods: The study group comprised 41 patients (26 males, 15 females, aged between 18-63 years, mean age 45 years), 23 with renal and 18 with ureteral stones, who underwent ESWL between March 2010 and January 2011. Colour Doppler ultrasonography and pulsed wave spectral analysis was performed before, 1 hour, and 7 days after ESWL to both ipsilateral and contralateral kidneys in order to measure resistive index (RI), pulsatility index (PI) and acceleration time (AT) values. Results: One hour after ESWL, RI and PI values showed significant increase from pre-ESWL values in both ipsilateral and contralateral kidneys. However, no significant change was found in AT values. Seven days after ESWL, PI in both ipsilateral and contralateral kidneys and RI in contralateral kidney returned to pre-ESWL values. But, 7 days after ESWL, RI in the ipsilateral kidney did not return to pre-ESWL values, although decrease in RI values were observed. Conclusion: Spectral Doppler analysis can provide valuable information as a non-invasive method to assess the hemodynamic changes and renal microcirculation status in cases managed with ESWL

Coenzyme Q(10) treatment reduces lipid peroxidation, inducible and endothelial nitric oxide synthases, and germ cell-specific apoptosis in a rat model of testicular ischemia/reperfusion injury

WOS: 000273601200042PubMed: 19683231In this experimental study, we assessed the preventive effects of coenzyme Q(10) (CoQ(10)) in a rat model of ischemia/reperfusion injury. The results of this study show that CoQ(10) administration before the reperfusion period of testicular torsion provides a significant decrease in testicular lipid peroxidation products and expressions of inducible nitric oxide synthase, endothelial nitric oxide synthase, and germ cell-specific apoptosis.
