[Cranial trauma: the predictability of the presentation symptoms as a screening for radiologic study].
A prospective study was performed on 4,262 consecutive patients who had had skull examinations for recent head trauma. Clinical signs and symptoms and patient history were correlated with skull fractures and intracranial sequelae as identified on CT studies, in order to evaluate the predictive value of each clinical finding and to identify high-yield referral criteria. Ninety-seven skull fractures (3%) and 32 intracranial sequelae (0.7%) were observed. ⋯ The most predictive finding for brain injury was the depressed level of consciousness: brain injuries were never observed in fully conscious patients; in altered consciousness with GCS 15-13 we observed 4% of skull fractures with no sequelae; at GCS values 12-9, 61% of skull fractures and 20% of sequelae were present, whereas at GCS less than 8, 100% of complicated fracture were observed. The finding of skull fracture showed 33% of predictivity for brain damage, which was, however, always associated with "high or moderate risk" clinical signs. Therefore, the authors suggest some guidelines for the management of patients with recent head trauma, including referral criteria for X-rays or CT studies, based on signs and symptoms with high, intermediate and low risk of developing intracranial sequelae.

Comparative Study[The incidence of disk changes in volleyball players. The magnetic resonance findings].
In order to evaluate the to potential hazards related to athletic functional overload on the intervertebral disk we studied with MRI the incidence of intervertebral disk abnormalities in a group of 45 volunteers who had been playing professional volleyball for 3-7 years. As a control group we examined with MRI 30 professional swimmers as well. Among the volley-ball players the incidence of intervertebral disk alterations was 44.4%; they were represented by 8 cases of disk degeneration, 11 cases of bulging and 9 disk herniations (in 8 patients the simultaneous presence of more than one lesion was observed). ⋯ Among the 26 athletes who were trained with exercises that caused significant functional overload, 16 had intervertebral disk lesions at MRI (61.5%). Moreover, our data showed that the correlation of the incidence of disk lesions with the type of training (and relative varying degree of overload) is definitely more important than the one existing with the age of volley-ball players and the overall period of their athletic activity. MRI proved to be a useful technique for the early assessment of the intervertebral disk damage caused by an incorrect training in young athletes, even when asymptomatic.
