ReviewAlbumin and lipid enriched albumin for the critically ill.
Albumin, the principal transporter of plasma fatty acids, binds to majority of the drugs ingested, traps oxygen radicals and has potent anti-oxidant actions. Albumin binds to its specific binding sites on vascular endothelial cells and thus, prevents endothelial apoptosis. Albumin regulates the enzyme pyruvate dehydrogenase, the flux of glucose and lactate in astrocytes, and enhances the formation of anti-inflammatory lipoxins, resolvins and protectins from docosahexaenoic acid (DHA) and other polyunsaturated fatty acids that, in turn, could limit ischemia-induced neuronal damage. This may explain the beneficial action of DHA-enriched albumin in stroke and other critical diseases.

ReviewVitamin D status in India--its implications and remedial measures.
Vitamin D deficiency is epidemic in India despite of plenty of sunshine. The interpretation of vitamin D levels should be done with the solar zenith angle, minimal erythemal dose, skintype, UV Index and geographical location. All Indian studies uniformly point to low 25(OH)D levels in the populations studies despite abundant sunshine. ⋯ The effect of short course of loading doses of vitamin D doesn't have a lasting effect and a maintenance dose is needed. Low 25(OH)D levels has its implications of lower peak bone mass and lower BMD compared to west. There may be a public health need to fortify Indian foods with vitamin D.

Case ReportsIsoniazid toxicity presenting as status epilepticus and severe metabolic acidosis.
Isoniazid (INH) is an integral component of treatment of tuberculosis. An acute overdose is potentially fatal and is characterized by the clinical triad of repetitive seizures unresponsive to the usual anticonvulsants, metabolic acidosis with a high anion gap and coma. The diagnosis of INH overdose should be considered in any patient who presents to emergency medical services (EMS) with the triad. We report a patient presenting with multiple generalised tonic clonic (GTC) convulsions with severe metabolic acidosis as a manifestation of INH toxicity.
