Extradural haematomas: how many deaths can be avoided? Protocol for early detection of haematoma in minor head injuries.
Since 1988 in the referral area of the Neurosurgical Unit of Cesena, Italy, a protocol for prevention of deterioration in minor head injury was adopted. Adult patients admitted to any hospital with a GCS score of 15 and 14 (transient) without neurological deficit are submitted to skull x-ray: if a fracture is present the patient is sent for CT to the nearest regional Center. In children skull x-ray is not routinely performed and the patients are admitted for observation to the nearest regional hospital. ⋯ Most of the patients deteriorated either during transport after being recognized as at risk or already in Neurosurgery allowing rapid surgical treatment. b) Impaired consciousness (18 cases) and c) Minor head injury (50 cases) are groups of patients treated without morbidity and mortality. If we compare these results with those of a previous study of our group done in 1980-86, there is a statistically significant difference concerning both mortality and morbidity. Our protocol proved therefore to be adequate in preventing most deaths that occurred following clinical deterioration in an apparently low risk patient.

Case ReportsTension pneumocephalus after transsphenoidal surgery: two case reports.
In this paper, a brief information on factors taking role in intracranial air formation and tension pneumocephalus because of two cases epidural air formation and tension pneumocephalus following transsphenoidal operation is presented. Two cases were treated conservatively.

CT and clinical criteria for conservative treatment of supratentorial traumatic intracerebral haematomas.
In search of guidelines for the management of traumatic intracerebral haematomas (TICHs) with slight mass effects on computed tomography (CT) scans, the author reviewed the records of 29 patients who did not undergo surgery and 11 patients who did. It is found that patients with a TICH volume of less than 15 ml, a midline shift of less than 5 mm, an open perimesencephalic cistern on CT scans, a Glasgow Coma Scale (GCS) score of 12 or more, and an absence of lateralizing signs may be treated conservatively and expected to make a good recovery. On the other hand, with zero mortality and satisfactory outcomes, the patients under-going early surgery tended to have a TICH volume of more than 15 ml, a midline shift of more than 5 mm, an obliterated perimesencephalic cistern on CT scans, a GCS score of less than 12, and the presence of lateralizing signs. However, the position of such features as the criteria of early operation for a TICH is weakened by the retrospective nature of this study because some surgical patients, free of lateralizing signs in particular, might have managed to do well without craniotomy.

Perimesencephalic and nonperimesencephalic subarachnoid haemorrhages with negative angiograms.
van Gijn and co-workers identified "Perimesencephalic haemorrhage" (PM) as distinct, benign, non-aneurysmal subarachnoid haemorrhage. However, there is only one retrospective series of this entity outside the Netherlands. ⋯ This study confirms that perimesencephalic haemorrhage is a distinct entity within the larger group of subarachnoid haemorrhage with negative angiograms, with a good short term and long-term prognosis, and no need for repeated angiographic investigation.

Thoracic percutaneous facet denervation has been employed for the treatment of thoracic zygapophysial joint pain. But the surgical anatomy of this procedure has been assumed to be the same as for lumbar medial branch neurotomy. To establish the anatomical basis for thoracic medial branch neurotomy, an anatomical study was undertaken. ⋯ Although the curved course remained essentially the same, the inflection occurred at a point superior to the superolateral corner of the transverse process. At no time during the dissection were nerves encountered crossing the junctions between the superior articular processes and transverse processes which have been the target points advocated for thoracic facet denervation. Rather, the results of this study indicate that the superolateral corners of the transverse processes are more accurate target points.
