Between 6.5% and 15.0% of all strokes occur in patients already in hospital, many of whom are there for surgical procedures or cardiac disorders. This important group of patients could potentially be assessed more rapidly than others and could be candidates for interventional therapies. However, delays in recognition and assessment are common, possibly related to comorbidities and the complexities of hospital practice. ⋯ In the postoperative setting, intra-arterial thrombolysis is feasible and reasonably safe in carefully selected patients. Experimental agents and the manipulation of physiological variables are other treatment possibilities that could be applied early in this group of patients. Increasing the awareness by hospital physicians of such interventions may be an important factor that reduces delays in assessment of patients who have stokes while in hospital.

Functional roles and therapeutic targeting of gelatinase B and chemokines in multiple sclerosis.
Multiple sclerosis (MS) is a demyelinating disease of the CNS of unknown cause. Pathogenetic mechanisms, such as chemotaxis, subsequent activation of autoreactive lymphocytes, and skewing of the extracellular proteinase balance, are targets for new therapies. ⋯ Blockage of chemotaxis or cell adhesion molecule engagement, and inhibition of hydroxymethyl-glutaryl-coenzyme-A reductase to lower expression of gelatinase B, may become effective treatments of MS, alone or in combination with interferon beta. This may allow interferon beta to be used at lower doses and prevent side-effects.

Cognitive impairment during epileptiform discharges: is it ever justifiable to treat the EEG?
Epileptiform EEG discharges are not confined to people with epilepsy, and their frequency is only weakly related to severity. A fundamental principle of EEG practice is, therefore, to avoid overinterpretation of epileptiform activity. Epileptiform discharges not accompanied by obvious clinical events are generally regarded as subclinical or interictal. ⋯ In children it may be associated with behavioural disorders. An important practical issue is whether TCI materially impairs psychosocial function and, if so, whether drug treatment is desirable or effective. Uncontrolled reports and two preliminary randomised controlled trials of antiepileptic treatment of TCI have suggested that suppression of discharges is associated with significant improvement in psychosocial function.
