Cyclin D1, Ret and P27 Expression in Papillary Thyroid Microcarcinoma.

Th e aim of the study was to determine the influence of RET, p27 and cyclin D1 on regional lymph node metastases in papillary microcarcinoma. The analysis included 70 patients with papillary thyroid microcarcinoma that underwent surgery at Split University Hospital Center between 1999 and 2001. Immunohistochemistry was performed on formalin-fixed, paraffin-embedded tissue by the RET, p27 and cyclin D1 antibodies.

A decrease in blood pressure following pyelolithotomy but not extracorporeal lithotripsy.

Our aim was to evaluate the hypothesis that relief of renal obstruction lowers the arterial blood pressure if the procedure of stone removal does not injure the kidney itself. Sixty patients with unilateral renal stone were evaluated at baseline and 3 months after electrical shockwave lithotripsy (ESWL, n=30) or Gil-Vernet intrasinus pyelolithotomy (n=30). Blood pressures were measured noninvasively and renal vascular resistances were obtained from radionuclide measurements of renal blood flow.

Pyelolithotomy improves while extracorporeal lithotripsy impairs kidney function.

Purpose: Extracorporeal shock wave lithotripsy (ESWL) causes acute depression of kidney function, which chronically returns to baseline levels. This sequala could indicate chronic regression of acute lesions or a balance between lesions and relief of obstruction. We compared changes in kidney function 1 week and 3 months after ESWL and pyelolithotomy.
