Abstract Taurine, a sulphur amino acid found endogenously in human and in several others. It is significantly in higher concentration in mammals and has a number of physiological and pharmacological actions and also used in the therapy of important organ dysfunctions. It is essential for cat and conditional for humans. A patient on parenteral nutrition (PN) may develop taurine deficiency which may hamper proper growth and development.

Abstract The aggravation of cerebral ischemic neuronal damage by preischemic hyperglycemia has been lauded as the proof that lactic acidosis is a major detrimental factor in such damage. This phenomenon has steered clinicians to attenuate blood glucose levels as a means of brain protection against the risk of ischemia during cardiopulmonary bypass surgery and neurosurgical procedures. Researchers who use in vivo models of ischemia have repeatedly confirmed this paradoxical phenomenon where the only energy substrate capable of supporting ATP formation in the absence of oxygen must be avoided.

Central diabetes insipidus (DI) is a very rare sequela of near-drowning. We report this case to add to the limited existing knowledge of this highly unusual complication in this group of patients. A young female rescued from fresh water submersion developed polyuria associated with hypernatremia 4 days after the accident. Desmopressin (DDAVP) was used to control the inappropriate diuresis and stabilize her intravascular volume and tonicity. Despite satisfactory re- sponse to DDAVP, she remained in a comatose state and cardiac arrest supervened 18 days after the accident.

For much of medical history, the precise mechanism of sudden cardiac arrest was assumed to be the abrupt cessation of activity in diastole. Not until the nineteenth century was ventricular fibrillation recognized as the causative entity, and not until the late twentieth were practical electrical defibrillators developed for terminating this dysrhythmia. Timely defibrillation is considered by many to be the most important single factor in successful cardiac arrest resuscitation.
