Colorectal cancer screening programme by faecal occult blood test in Tuscany: first round results.

Screening with faecal occult blood test (FOBT) has been shown to be effective in reducing mortality from colorectal cancer. Tuscany was the first region in Italy in which a screening programme for colorectal cancer by FOBT was initiated region-wide. The aim of the paper was to describe organizational aspects, a quality control model and the results of this experience.

Varicocele in prepubertal boys. Evaluation of clinical Doppler and hormonal findings.

Hormonal, clinical and scrotal Doppler findings were assessed in 16 prepubertal patients having unilateral varicocele. As already described in pubertal patients, Doppler studies made it possible to detect patterns of prolonged, intermittent or permanent reflux. An LH-RH test and an hCG test measuring LH, FSH and testosterone (T) were performed in all cases.

Pubertal varicocele: correlation between clinical, Doppler, and hormonal findings.

Clinical, Doppler, and hormonal findings in puberal patients with unilateral and bilateral varicocele were evaluated. No correlation was found between clinical and hormonal findings. A significant increase was found in LH response to LH-RH in patients with bilateral varicocele as well as an increase in T to hCG in those with unilateral varicocele with prolonged reflux.
