Primary glaucomas: current concepts and management.

Glaucoma is a leading cause of blindness. Delay in diagnosis of open angle glaucoma (OAG) results from lack of symptoms. In angle closure glaucoma (ACG) there is often neglect of symptoms. Creating awareness about the disease and screening the high risk groups would reduce the burden of irreversible blindness due to glaucoma. Adequate therapy in the form of drops, lasers and surgery is available. Close interaction with the physician is important as many topical antiglaucoma medications have adverse systemic side-effects and many drugs used for systemic diseases raise the intra-ocular pressure (IOP). All drugs currently available for glaucoma lower IOP but new drugs for neuroprotection may change the future management strategies. While drugs and surgery are the mainstay for OAG, laser iridotomy is the definitive treatment for ACG.

Sterilisation of tonometers and gonioscopes.

Precautions to prevent spread of infection through tonometers and gonioscopes are described in this article. Tonometers and gonioscopes should not be used in the presence of clinically manifest conjunctivitis and keratitis. The Schiotz tonometer should be dipped in a 1:1000 merthiolate solution, and rinsed in saline/distilled water prior to use. The Goldmann applanation prism tip can be wiped with gauze soaked in 70% isopropyl alcohol and then dried before use. Gonioscopes should be cleaned in running water, wiped with gauze soaked in 70% isopropyl alcohol, and then dried before use. Koeppes and goniotomy lenses can be sterilized with ethylene oxide, prior to use in surgery.

Isolation of poliovirus from cases of acute flaccid paralysis.

OBJECTIVE: To evaluate the frequency of isolation of polio and other viruses from fecal samples in subjects with acute flaccid paralysis in northern parts of India. SETTING: Rural and Urban Immunization Centers used for Expanded Programme on Immunization. METHODS: 219 fecal samples were collected by anal tube in 1992 from Punjab, Haryana, Himachal Pradesh and Chandigarh and processed for virus isolation. RESULTS: Of 219 fecal samples, 103 (47%) were positive for viruses in the age group of 3 mo to 5 yr. Amongst the positive samples, the predominant isolated was poliovirus type 1 (70.9%) from all the States. Non polio enteroviruses were isolated from 20.4% of fecal samples. CONCLUSION: Even though poliovirus is still the most common etiologic agent for acute flaccid paralysis in northern India, non polio enteroviruses are also emerging as important causal pathogens in this condition.

Leucocyte migration inhibition in cow's milk protein intolerance.

The leucocyte migration inhibition (LMI) was determined in an assay after in vitro challenge with beta-lactoglobulin. The assay was considered positive when migration inhibition index was greater than 20% (mean +3 SD of healthy infants). Ninety-eight infants with protracted diarrhoea and failure to thrive, 16 healthy, 12 malnourished, and 16 infants suffering from acute gastroenteritis were studied. Of the 98 patients with protracted diarrhoea, 12 fulfilled Goldman's criteria for cow's milk protein intolerance, 63 had lactose malabsorption, and in 15 no associated causative factor was identified. The mean index of migration inhibition in the cow's milk allergic group (58.83 +/- 11.98) was higher than in healthy controls (8.25 +/- 3.91), the difference being statistically significant (p less than 0.05). The test was positive in all patients with cow's milk protein intolerance. The assay was also positive in four other patients suffering from protracted diarrhoea, two of whom had lactose malabsorption. All the infants with acute gastroenteritis and malnutrition had values within the normal range. The migration inhibition index in five patients with cow's milk intolerance had declined to 24.74 +/- 4.87 in assays performed 1-6 weeks after return of clinical tolerance to cow's milk (p less than 0.05) but the test was still within the positive range in three of the five infants. These results suggest that this cell mediated immune assay is a sensitive test for the diagnosis of cow's milk protein intolerance in infants. The specificity needs to be reassessed in the light of more objective criteria for the diagnosis of cow's milk protein intolerance.
