Lowering the blood pressure (BP) of patients with intracerebral haemorrhage (ICH) can prevent haematoma enlargement but may also promote secondary infarction in areas adjacent to the haematoma, which can lead to neurological deterioration. Little is known about the effects of low BP on early neurological deterioration (END). We conducted a retrospective study to determine whether low BP after admission was associated with END in patients with acute ICH. ⋯ Our findings suggest that a minimum SBP of approximately 120-125 mmHg after admission is associated with a beneficial impact on a reduced risk of END.

Cauda equina syndrome (CES) is a neurological syndrome presenting with non-specific symptoms and signs that often leads to diagnostic confusion and delay. Acute onset CES is a surgical emergency. The common aetiology is a prolapsed lumbar disc. ⋯ Presence of saddle sensory deficit was the only clinical feature with a statistically significant association with MRI positive CES (p = 0.03). This series shows that saddle sensory deficit has a higher predictive value than other clinical features in diagnosing a CES. However, as there is no symptom or sign which has an absolute predictive value in establishing the diagnosis of CES, any patient in whom a reasonable suspicion of CES arises must undergo urgent MRI to exclude this diagnosis.

A logical, rational and reasonable guideline for the management of patients with suspected cauda equina syndrome (CESS) is proposed. This article is intended to promote debate. Ideally spinal surgeons can agree a standard of care that can be applied nationally to the benefit of our patients, our colleagues and, as neurosurgeons and spinal surgeons, ourselves.

Case Reports
An unusual case of spontaneous subarachnoid haemorrhage - a ruptured aneurysm of a basilar perforator artery.
A 51-year-old gentleman with no significant past medical history presented with a WFNS grade 1 subarachnoid haemorrhage. Initial angiographic investigations revealed no cause, but repeat tests showed a small basilar perforator aneurysm. ⋯ Post-operatively the patient made a good recovery. This case highlights the importance of delayed repeat catheter angiography in selected patients with suspicious initial CT head results.

Microdialysate fluid from 145 severely injured NSICU-patients, 88 with subarachnoidal haemorrage (SAH), and 57 with traumatic brain injury (TBI), was collected by microdialysis during the first 7 days following impact, and levels of the neurotrophins fibroblast growth factor-2 (FGF2) and vascular endothelial growth factor (VEGF) were analysed. The study illustrates both similarities and differences in the reaction patterns of the 2 inflammatory proteins. ⋯ This is the first report presenting in some detail the human cerebral response of FGF2 and VEGF following SAH and TBI. Apart from increasing the understanding of the post-impact inflammatory response of the human brain, the study identifies potential threshold values for these chemokines that may serve as monitoring indicators in the NSICU.
