The metronome-based methodology to monitor the stroke length changes in trained swimmers.

The aim of our study was to develop a methodology that uses the metronome to constrain the swimmers' stroke rate with the aim to monitor changes in stroke length (SL) during two different periods of the season. Thirteen young trained swimmers (15.7 ± 1.

Muscle Fatigue and Swimming Efficiency in Behind and Lateral Drafting.

Drafting in swimming is a tactic in which an athlete (drafter) swims in the wave of another athlete (leader). Our aim was to compare the effects of this tactic on the drafter, as far as muscle fatigue, muscle activity, and swimming efficiency are concerned. Fifteen drafters performed three 200 m front crawl trials at a controlled submaximal pace in three configurations: Behind Drafting (BD), Lateral Drafting (LD), and Free Swimming (FS).

[Histological follow-up after implantation of grains of I-125 for prostatic cancer].

The authors report a preliminary study of 12 cases of carcinoma of the prostate confined to the prostate (T1, T2, T3, NO, MO) treated by pelvic lymphadenectomy and the implantation of grains of I 125 in the prostatic tissue. Irradiation continued for six months, providing most dose of 100 Gy in the prostate. Interstitial irradiation caused not only the destruction of tumour cells but also "radiation prostate" lesions with vascular obliteration which itself caused sufficient impairment of the vitality of the prostatic tissue for any residual tumour to disappear with a frequency which increased with the time elapsing between the follow up prostatic biopsy and the implantation of radioactive iodine.

[Embolization of the inferior mesenteric artery in hemorrhagic bladder neoplasms after failure of hypogastric arteries embolization].

The authors report 3 cases of revascularisation through the inferior mesenteric artery of bladder tumors which had previously been treated by transcatheter occlusion of both hypogastric arteries because hemorrhage. New uncomplicated embolizations of the inferior mesenteric artery are performed in 2 cases and recurrency of the bleeding was stopped.

[Percutaneous dilatation of renal artery stenoses. Apropos of 7 cases].

The authors report the results of percutaneous dilatation of renal artery stenoses, performed on 8 occasions in 7 patients. One patient had bilateral stenoses which were operated at two separate occasions. The authors had no complications and they confirm the stability of the results with a follow-up of up to 2 years.
