Traumatic isolated oculomotor nerve palsy is not common. Oculomotor nerve palsy without internal ophthalmoplegia (pupil sparing) is extremely rare. We report a case of this condition in a child. ⋯ Magnetic resonance imaging indicated mild bending of the ipsilateral oculomotor nerve at the posterior petroclinoid ligament. One month after injury, movement of the patient's eyes was normal on examination, but there was mild diplopia. The suggested mechanism of the oculomotor nerve palsy with pupil sparing in this case is stretching of the oculomotor nerve at the posterior petroclinoid ligament, maintaining an intact pupillomotor nerve.

In the past 5 years, cerebral perfusion pressure (CPP) management has become the standard in the treatment of severe head injuries. Guidelines published in 2000 suggest that CPP should be at least 70 mmHg; however, there is still debate about the optimal CPP. The purpose of the present study was to evaluate the effectiveness of these three widely used therapies: (i) intracranial pressure (ICP) targeted; (ii) CPP-targeted with CPP >70 mmHg; and (iii) modified CPP-targeted (mCPP) therapy with CPP >60 mmHg. ⋯ Highest intake/output ratio, amount of vasopressor used and pulmonary complications were seen in the CPP patients. The mCPP patients showed the best clinical outcome and lowest complication rate. Although CPP-targeted therapy is the most recommended therapeutic protocol, our data show that patients treated with modified CPP-target therapy with CPP >60 mmHg have better clinical outcomes and fewer complications.

S100-B and neuron specific enolase (NSE) are known predictors of outcome in head injured and stroke patients. This study was conducted to test the hypothesis that S-100B and NSE can predict the development of vasospasm and outcome within the first 3 days after subarachnoid haemorrhage (SAH). Fifty-one SAH patients (mean age 51+/-11 years, male : female ratio 1.0 : 1.6, mean World Federation of Neurological Surgeons [WFNS] Grade 3+/-1.5) were included in the study. ⋯ NSE was normal, intermediate and high in 82%, 8% and 10% of patients, respectively. Patients with WFNS 4-5 and/or Fisher Grade 4 had significantly higher NSE values than all others. Across the first 3 days after SAH, measuring S-100B is useful to predict outcome and vasospasm.
