[Changes in the lumbosacral spine caused by sports microtraumas]. / Alterazioni del rachide lombosacrale da micropolitraumatismi sportivi.

The results are reported of a clinical and radiological study of a group of athletes that investigated the often asymptomatic alterations found in the spinal area. In comparison with non-athletic controls the sportsmen revealed a significantly higher incidence in the pars intearticularis of the posterior apophysis in the lumbar region. Practitioners of sports requiring violent spasmodic effort also revealed spondylolysis and spondyloisthesis. The early appearance of lumbar degenerative arthritis in practitioners of sports requiring moderate but sustained effort was also statistically significant.

[Emergency heart stimulation with a transthoracic electrode. Our experience in 35 cases]. / La stimolazione cardiaca d'urgenza con elettrodo transtoracico. Nostra esperienza in 35 casi.

35 cases of heart stimulation using a transthoracic electrode are presented. It is emphasised that the technique is only applicable in very few cases (total AVB with a critical frequency below 20/min, all types of asystolia). The simple technique, results and complications (in theory many but in practice only 1 occurred) are briefly described.
