This study reports 3 cases of pure hemisensory syndrome due to lacunar infarction at the pons, demonstrated by magnetic resonance. In all patients somatosensory evoked potentials were abnormal. In two out of the 3 cases these potentials remained abnormal even after clinical exploration normalized. ⋯ None of them had data on somatosensory potentials. In our experience the study of somatosensory evoked potentials has a high sensitivity. It appears that the distribution of the sensitive defect is independent of the location of the structural lesion.

We present the epidemiology and the outcome of the patients younger than 15 years-old who were admitted to our hospital during 1986 with the diagnosis of head injury. One hundred and fifty-five met the required inclusion criteria, this offers an incidence of head injury in children of 139/100,000. The boy/girl ratio was 2.1/1. ⋯ There were two intrahospital deaths, that happened in the 8 patients with severe head injury, giving a mortality rate of 25% for this group; and 5 deaths out of hospital. Thus, the global mortality secondary to head injury for children was 6.3/100,000 and year. These data show: a) the sanitary importance of the head injury in children; b) the necessity of a separate study of the head injury in children since the precipitating causes and the clinical outcome are specific; and c) the shortcomings in the urgent out of hospital medical attention, as indicates an out of hospital mortality rate of 71% which is well above that of other developed countries.
