RESUMO
Very few immunological studies in vernal catarrh have been conducted in India and abroad, but none in Himachal Pradesh in spite of its high incidence in the State. In the present study 25 patients of vernal catarrh residing at a height ranging between 1000 to 2500 meters above mean sea level have been evaluated. Their immunological status of serum and tears after detailed clinical assessment was studied by single radial immunodiffusion technique of Mancini et al. The values of serum IgA and IgM were significantly higher in patients than in controls. The serum IgE level had no significant difference. The IgG was significantly lower in patients with vernal catarrh. The values of tear IgM, IgE and IgA in these patients were significantly higher than in controls. However, in no case or control group C3C and C4 were detected in tears. The limbal type of vernal catarrh was found to be the most common in this part of the country. No mixed case was seen. Derangement of the immune system in the pathogenesis of vernal catarrh is suggested.

The accuracy of a non-invasive estimation of systolic pulmonary artery pressure in 33 patients with ventricular septal defect and/or tricuspid regurgitation, by colour guided continuous wave Doppler was evaluated. The estimated pulmonary artery pressure correlated well with values obtained at cardiac catheterization (r = 0.93). Correlation was better in cases with ventricular septal defect (r = 0.98) than in cases with tricuspid regurgitation (r = 0.87). Pulmonary artery pressure was under-estimated in cases with mild tricuspid regurgitation, probably due to eccentricity of regurgitant jet in some of these cases.
