Activation of blood coagulation after aneurysmal subarachnoid haemorrhage: a prospective observational trial by rotational thromboelastometry (ROTEM ®)
Aneurysmal subarachnoid haemorrhage (aSAH) is reported to actuate blood coagulation. Rotational thromboelastometry (ROTEM ®) is a dynamic haemostatic test that can differentiate various coagulation abnormalities, for example, increased coagulation activity can be detected as a wider amplitude of tracing (maximal clot firmness [MCF]). Previously, ROTEM® has not been used to evaluate coagulation changes after aSAH. The aim of this prospective, observational study was to evaluate the on-going coagulation process in patients with aSAH by comparing their ROTEM assay results to the control values obtained from patients u...

Carotid Stenosis: Utility of Diagnostic Angiography
Carotid artery stenosis is frequently diagnosed through screening tests with non-invasive imaging. Because of differences noted between the various modalities, we sought to investigate our experience comparing non-invasive imaging (ultrasound, CT angiography, MR angiography) with invasive imaging (digital subtraction angiography). In a multi-center retrospective analysis, 249 carotid vessels were reviewed based on angiography with the associated non-invasive imaging. Overall, medical or surgical decision management was changed in 43% (107/243) of cases investigated with digital subtraction angiography due to a discrepancy ...

Factors influencing medical student interest in a career in neurosurgery
Exposure to neurosurgery at the undergraduate level is an important factor in determining future interest in, and applications to, the specialty. Given the high competition for training posts, this exposure is also becoming an almost essential addition to an applicant ’s portfolio. For this reason, we organised a neurosurgical conference aimed at undergraduate medical students. We aimed to determine factors attracting and deterring students from the specialty before and after this conference. (Source: World Neurosurgery)

An Unusual Presentation of Chronic Subdural Hematoma with Isolated Footdrop
Patients with chronic subdural hematoma typically present with symptoms of increased intracranial pressure including headache, nausea/vomiting, and somnolence or with contralateral weakness. Compression of the convexity cerebral cortex usually causes motor deficit that is more readily appreciated in the upper extremity rather than in the leg, and very subtle deficit may be only detected by looking for pronator drift. The precise pattern of signs and symptoms in a given patient with chronic subdural may vary from case to case depending upon the specific anatomy of compression, but isolated lower extremity weakness is rare. ...
