Background: Fecal incontinence is defined as involuntary passage of stool through the anus. It may vary from soiling to complete evacuation. This involuntary loss of feces, flatus or urge incontinence adversely affects quality of life. Urinary urge incontinence is characterized by symptoms of frequency, urgency and urge incontinence (either alone or in combination). Urgency frequency syndrome is defined as symptoms of frequency and urgency without incontinence episodes.

Objectives: To evaluate the efficacy of sacral neuromodulation on these pathologies. 

Methods: Following a detailed investigation, 51 patients with either urinary or fecal incontinence, or both, who did not respond to medical and behavioral treatment were offered the temporary implant. Of the 51 patients 40 showed improvement and advanced for a permanent device.

Results: After a mean follow-up of 5 years (range 1–8), there was a significant reduction in the number of incontinence episodes (P < 0.0001), and the number of pads used also declined significantly (P < 0.0001). A marked improvement in quality of life was reported by 71.4% of the women and 58.3% of the men.

Conclusions: Sacral neuromodulation as shown in this study appears to be a promising treatment for urinary and fecal incontinence and can dramatically improve patients' quality of life.

 

Background: The precise genes involved in conferring prostate cancer risk in sporadic and familial cases are not fully known.

Objectives: To evlauate the genetic profile within several candidate genes of unselected prostate cancer cases and to correlate this profile with disease parameters.

Methods: Jewish Israeli prostate cancer patients (n=224) were genotyped for polymorphisms within candidate genes: p53, ER, VDR, GSTT1, CYP1A1, GSTP1, GSTM1, EPHX and HPC2/ELAC2, followed by analysis of the genotype with relevant clinical and pathologic parameters.

Results: The EPHX gene His113 allele was detected in 21.4% (33/154) of patients in whom disease was diagnosed above 61 years, compared with 5.7% (4/70) in earlier onset disease (P < 0.001). Within the group of late-onset disease, the same allele was noted in 5.5% (2/36) with grade I tumors compared with 18% (34/188) with grade II and up (P = 0.004). All other tested polymorphisms were not associated with a distinct clinical or pathologic feature in a statistically significant manner.

Conclusions: In Israeli prostate cancer patients, the EPHX His113 allele is seemingly associated with a more advanced, late-onset disease. These preliminary data need to be confirmed by a larger and more ethnically diverse study.
