Entrapment neuropathy of the internal pudendal nerve in the Alcock canal is a rare entity and literature on the subject is lacking. The pathogenesis of this disease is probably related to repeated microtraumatisms of the perineal region acting on the Alcock canal or dysmetabolic diseases favouring compression of the pudendal nerve inside the Alcock canal. In this article two new cases which have come to our attention are described and literature on the topic, with special regard to diagnosis and treatment, is reviewed.
We have executed 183 cranioplasties in order to repair cranial defects using stainless steel wire mesh over a period of a decade, using Gardner's technique with minor modifications. The follow-up was possible in 100 patients and it ranged from 4 to 134 months, with an average of 64.1 months (5.3 years). Among these, 8 patients developed postoperative complications (8%): 7 needed cranioplasty remotion (7%) and 1 needed cranioplasty revision without remotion (1%). The causes of morbidity were due to: infection (3%), CSF leak (1%), haematoma (1%), skin local soaking (1%), posttraumatic plastic dislodgement (2%). Our total morbidity rate (8%) may compare with that resulting from the use of different materials such as alloplastics (6-12%), osteoplastics (until 40%) and miscellaneous (5.5%). The group in which cranioplasty was done within six months following the first operation had our highest complication rate (18.2%). In our experience the stainless steel wire mesh was shown to be an effective material to repair cranial defects.
A case of cerebellopontine angle petrous bone osteoma manifesting as homolateral trigeminal neuralgia and causing a mild brain stem compression is presented. The literature concerning osteomas and particularly those affecting the temporal bone is reviewed. This is the second report of an osteoma located on the inner surface of the petrous bone and causing intracranial complications. Moreover, we discuss the intracranial tumors presenting with trigeminal neuralgia or atypical facial pain.
A 35-year-old basketball player suffered a serious double head injury during a match. An (Figure 1). The patient's haematoma was then evacuated via a left temporal parietal craniotomy. At surgery, a double vertical fracture of the temporal and parietal bones was found, which had not been appreciated at radiography. The postoperative course was uneventful and 10 days later the patient, in a satisfactory condition, was
DiscussionAccording to statistics compiled by the US National Center for Catastrophic Sports Injury Research, the sports with the highest incidence of catastrophic head or neck injuries include football; gymnastics; ice hockey and wrestling. Other sports in which there is a significant possibility of head injury include the pole-vault; baseball; horse racing; motorcycle, automobile and boat racing; sky diving; boxing; martial arts and rugby'. Golf, shooting, climbing and skating were also reported2.Basketball has traditionally been regarded as having a low risk of nervous system injuries even if it has the highest frequency of college non-collision sport injuries3. The only report which we found concerning a potentially catastrophic head injury, during a basketball game, which evolved into an acute intracranial haematoma, concerned a 17-yearold boy who was struck on the left side of the head by a ball rebounding off the metal rim of the basket. The boy underwent frontal-temporal craniotomy in order to evacuate the acute subdural haematoma as well as 95
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
