Status epilepticus is a medical emergency that requires rapid seizure control. Intravenous bolus diazepam has been used in the rapid reversal of status epilepticus; this agent usually is combined with parenteral phenobarbital or phenytoin for a more sustained suppression of seizure activity. In certain situations, these longer-acting agents are not effective in controlling the seizure disorder, necessitating alternative therapeutic measures. Continuous diazepam infusion has been used successfully to treat persistent seizure activity. Its use, however, is fraught with pharmaceutical problems. This article reviews the pharmacology, efficacy, and pharmaceutical results of using continuous infusion intravenous diazepam to treat status epilepticus.

A Rare Case Report of Dengue Fever Presenting With Acute Leukoencephalopathy With Restricted Diffusion.

Acute leukoencephalopathy with restricted diffusion (ALERD) is an emerging clinico-radiological syndrome marked by sudden onset encephalopathy and characteristic restricted diffusion in the subcortical white matter on MRI. While typically linked to other viral etiologies, its association with dengue fever is not well known and is rarely documented in the literature. In this report, we describe a rare case of ALERD associated with dengue fever in a young patient, emphasizing clinical features, neuroimaging findings, management, and outcome.

Acute intermittent porphyria (AIP) is a rare inherited metabolic disorder caused by decreased activity of the enzyme porphobilinogen deaminase in the heme synthesis pathway. This leads to the accumulation of toxic porphyrin precursors, such as porphobilinogen and δ-aminolevulinic acid. Clinical manifestations typically include episodic bouts of severe neurovisceral pain and autonomic dysfunction.

Cortical spreading depolarization (CSD), a slowly propagating wave of transient cellular depolarization, is a reliable cortical response to various brain insults (stroke, trauma, seizures) and underlying mechanism of migraine aura. Little is known about CSD effects on brain network activity. Using undirected (mutual information, MI) and directed (transfer entropy, TE) measures, we studied the dynamics of cross-hemispheric connectivity associated with the development of unilateral CSD in freely behaving rats and the involvement of inhibitory transmission in mechanisms of the coupling changes.

The free-living amoeba (NF) causes a rare but lethal parasitic meningoencephalitis (PAM) in humans. Currently, this disease lacks effective treatments and the specific molecular mechanisms that govern NF pathogenesis and host brain response remain unknown. To address some of these issues, we sought to explore naturally existing virulence diversity within environmental NF isolates.

Scleroderma is a rare connective tissue disease categorized as systemic or localized. Linear subtype of localized scleroderma usually manifests as a cutaneous linear scar-like lesion most commonly on the scalp. It may present with neurologic, ophthalmologic, and rheumatologic symptoms.
