Meningococcal disease--outbreak in Delhi.

Meningococcal disease occurs both endemically and epidemically across the world. In India also meningococcal disease occurs sporadically with epidemics occurring at regular intervals. Epidemics of meningococcal disease have occurred in Delhi in the year 1935, then in the year 1966 which lasted for a year and again in 1985-86. The last epidemic took a great toll with case fatality rate nearly 13%. This year also there has been an outbreak of meningococcal disease with nearly 400 cases and case fatality rates of about 10% majority are males between the age group of 21-30 years and from the inner crowded areas of the city.

A rat model of radiofrequency ablation of trigeminal innervation via a ventral approach with stereotaxic surgery.

Neurotrophic keratopathy (NK), a consequence of sensory denervation of the cornea, must be better understood in order to develop new approaches to therapy. The purpose of this study was to create a rat model for neurotrophic keratopathy by denervating the trigeminal nerve through a ventral approach with stereotaxic surgery. Stereotaxic coordinates were measured in 46 male Sprague Dawley rat cadavers for localization of V1. After further refining the coordinates in nine live animals, radiofrequency ablation was chosen as an effective method of disrupting the innervation to the cornea. Fifty-two live rats were treated with radiofrequency ablation to define the anatomical localization of the lesion by utilizing gross and histopathological studies. A gross lesion of the trigeminal nerve and/or ganglion was observed in 47 (90%) of the 52 animals. Histopathological studies revealed that all 52 animals had anatomical damage of the trigeminal innervation to the eye. Low mortality and little morbidity were observed in these animals. We have developed a rat model for neurotrophic keratopathy that is simple to produce, accurate in creating a lesion by utilizing stereotaxic techniques combined with radiofrequency ablation, and successful in decreasing morbidity and mortality.

Stroke in children.

Stroke is a thrombohemorrhagic disorder of the central nervous system, with a fairly good outcome in pediatric age group except for the infancy period. In children ischemic type is more common than hemorrhagic type. Though it is difficult to distinguish between thrombotic and embolic phenomenon but it is largely due to cardiovascular lesions, at times it may be the first symptom to appear. The signs and symptoms also appear to be vague in children, hence difficult to pinpoint the etiology. The treatment of stroke is largely for stabilization of the patient, but it is very important to know the cause to prevent future strokes. Use of heparin in ischemic stroke is very promising and thrombolytic therapy is under trial.
