Case ReportsEarly diagnosis and treatment reverse clinical features in Hoffmann's syndrome due to hypothyroid myophaty: a case report.
Hypothyroidism is a frequently diagnosed endocrine disorder that has characteristic clinical signs and symptoms. Myopathy is one of the manifestations of hypothyroidism and relatively common. ⋯ He was diagnosed with Hoffmann's syndrome with low levels of thyroid hormones and high levels of muscle enzymes. After six months of thyroid hormone replacement therapy, both the clinical picture and laboratory findings were remarkably improved.

ReviewStandards of care for adults with convulsive status epilepticus: Belgian consensus recommendations.
Status epilepticus (SE) is a significant health problem, affecting approximately 1,000 to 4,000 individuals per year in Belgium. A workshop was convened by a panel of neurologists from major Belgian centers to review the latest information relating to the definition, diagnosis and treatment of convulsive SE. The panelists sought to make recommendations for practising neurologists, but also primary care physicians and physicians in intensive care units when initiating emergency measures for patients with convulsive SE. ⋯ If the patient does not recover after therapy, monitoring of seizures should involve an electroencephalogram to avoid overlooking persistence of clinically silent SE. As a general rule, the intensity of the treatment should reflect the risk to the patient from SE, and drugs likely to depress respiration and blood pressure should initially be avoided. If initial treatment with a benzodiazepine fails to control seizures, the patient must be referred to the emergency unit and a neurologist should be contacted immediately.

Neuroprotection of patients with acute ischemic stroke should start at the scene and continue in the ambulance with the assessment and treatment of the airway, breathing, circulation, body temperature, and blood glucose. The key goal in eligible patients should be fast vessel recanalization with intravenous recombinant tissue-type plasminogen activator Results from a meta-analysis suggest that systemic thrombolysis is effective when given within 4.5 hours after stroke onset. The time window extends to 6 hours for patients undergoing intravascular thrombolysis. ⋯ Thus far, despite promising preclinical studies, clinical trials with neuroprotective drugs in acute ischemic stroke have been disappointing. However, we have been able to identify many of the factors that were responsible for these failures, and better-designed clinical trials with neuroprotective drugs should look more promising. Mild induced hypothermia is another form of neuroprotective treatment that is currently being investigated in acute stroke.

ReviewProphylaxis of the epilepsies: should anti-epileptic drugs be used for preventing seizures after acute brain injury?
In many circumstances antiepileptic drugs are used in patients who have never presented any clinical epileptic seizures. These substances are administered on the assumption of a potential risk for the patients of developing acute or delayed chronic seizures after brain injuries such as trauma, stroke, hemorrages or even neurosurgical interventions. ⋯ We will distinguish between the prevention of acute (early onset-provoked) seizures and a delayed truly post-lesional (unprovoked) epilepsy. Some therapeutic goals can be achieved under the former circumstances whereas in the latter situation we all agree for the absence of any coherent antiepileptic prophylactic behaviour.

Neurostimulation is an emerging treatment for refractory epilepsy. To date the precise mechanism of action remains to be elucidated. Better insight in the mechanism of action may identify seizure types or syndromes that respond to such a treatment and may guide the search for optimal stimulation parameters and finally improve clinical efficacy. ⋯ Several hypotheses have been raised for the mechanism of action of DBS for refractory seizures. Seizure reduction may be due to a microlesion caused by electrode insertion or by provoking a reversible functional lesion due to the effect of electrical current on hyperexcitable tissue. Neurophysiological techniques such as evoked potentials monitoring and intraoperative single unit potential recordings may guide correct electrode placement, individual DBS titration and elucidation of the mechanims of action of DBS for epilepsy.
