Vagus nerve stimulation (VNS) is an established treatment for selected patients with medically refractory seizures. Recent studies suggest that VNS could be potentially useful in the treatment of resistant depressive disorder. Although a surgical procedure is required in order to implant the VNS device, the possibility of a long-term benefit largely free of(More)
We have reviewed all acute neurosurgical admissions between December 2007 and December 2009. Hundred and nine (46.6%) of our admissions were head injuries. A subdural haematoma(SDH) was found in 51.4%(56) of the head injuries. Of these, 50/56 presented with a Glasgow Coma Scale(GCS) of 14 to 15, 41.1% (23) of these SDH needed surgery. The commonest mode of(More)
Spinal cord stimulation (SCS) has been shown to be particularly useful, safe and effective treatment in the management of patients with refractory angina pectoris and those unsuitable for percutaneous or surgical revascularisation. Clinical and experimental research has shown that it decreases myocardial ischemia without masking the clinical symptoms of its(More)
A patient with a Spetzler-Martin-grade-III AVM, initially embolized and then stereotactically irradiated, who - with a latency of several months - showed progressive neurological deterioration, is reported. Magnetic resonance imaging revealed enormous ipsilateral brain oedema, which did not respond to dexamethasone. Upon further neurological deterioration(More)
Chordomas are relatively rare neoplasms that appear to originate from benign remnants of primitive notochord. They account for about 0.15% of all intracranial neoplasm and are the most common of extradural neoplasms that involve the clivus. Although they present mostly with signs and symptoms of other intracranial lesions they rarely present with high(More)
There has been a renaissance in the surgical management of Parkinson's disease. This has been due to long-term effects of levodopa and a better understanding of the basal ganglia and its circuitry. Ablative surgery and neurostimulation are the only realistic surgical options at present. Although surgical treatments, such as ablation and stimulation are(More)
BACKGROUND Motor vehicle accidents are the most common cause of spinal injuries in Saudi Arabia. Camel collisions usually result in cervical spine injuries. Although extremely rare, dorsal spine injuries have also resulted from these accidents. METHOD Retrospective analysis of the type of accident of all the patients with dorsal spine injuries was(More)
BACKGROUND Camel collision accidents are a common occurrence in Saudi Arabia, with a high rate of mortality and morbidity. Isolated injuries are rare because of the nature of impact sustained by the person. CASE DESCRIPTION A 4-year-old child with an isolated depressed skull fracture resulting from a camel collision is described. The other occupants of(More)
