Immunohistochemical pattern of T lymphocytes population within bilharzial-associated bladder neoplasm microenvironment.

The present work aimed to investigate the cellular and immunochemical pattern of T cells population in biopsy material from chronic schistosomiasis haematobium Egyptian patients complicated with bladder cancer. Digital real-time quantitative photocytometry was applied to auto-analyze 29 stained tissue sections from cases and 17 controls using STAT4, GATA3, FOXP3, and CD8 markers specific for Th1, Th2, T regulatory, and T cytotoxic cells, respectively. Area percentage showed significant high level of GATA, followed by FOXP3 and low level of both STAT and CD8 was reported.

Genomic instability in complicated and uncomplicated Egyptian schistosomiasis haematobium patients.

Background: Exploration of genetic changes during active Schistosoma infection is important for anticipation and prevention of chronic sequelae. This study aimed to explore the genomic instability in chromosomal and cellular kinetics in Egyptians suffering from uncomplicated active schistosomiasis haematobium infection in addition to chronic schistosomiasis haematobium cases complicated by bilharzial-associated bladder cancer (BAC).

Results: This study was conducted on 46 schistosomiasis haemotobium cases, 22 were active (Viable S.

Percutaneous nephrolithotomy in horseshoe kidneys: is rigid nephroscopy sufficient tool for complete clearance? A case series study.

Background: this study represents a case series to evaluate how successful is the rigid percutaneous nephroscopy as a tool for clearance of all stones in various locations in horseshoe kidneys.

Methods: Between 2005 and 2009, we carried out PCNL (percutaneous nephrolithotomy) for calculi in horseshoe kidneys in 21 renal units (17 patients) in our department. The indications were large stone burden in 18 units and failed SWL(shock wave lithotripsy) in 3 renal units.
