T and B lymphocytes in patients with enteric fever.

Estimation of T and B lymphocytes was done in 50 patients of enteric fever, 50 duration matched non enteric fever patients and 50 normal healthy individuals. The difference in both early and late rosette forming T lymphocytes was found to be statistically significant in enteric versus non-enteric patients. Significant difference was also observed in enteric versus normal individuals in case of late rosette forming T lymphocytes.     

Tear film profile in Graves' ophthalmopathy.

Tear film profile was studied in 30 patients with Graves' ophthalmopathy. Tear film pH, fluorescein staining, marginal tear strip and Schimer test values in patients with Graves' ophthalmopathy were comparable with controls, indicating normal tear secretion. Tear film break-up-time (BUT) in late Graves' ophthalmopathy was significantly low suggesting unstable tear film. Rose bengal as well as lissamine green staining intensity scores were significantly high, indicating presence of drying epithelial cells in early as well as late Graves' ophthalmopathy patients.     

Preserved vision in a case of morning glory syndrome: some pertinent questions

Morning glory syndrome, an unusual developmental anomaly of the optic nerve head, presenting with funnelled enlargement of the disc with a white dot in the centre and a peripheral vascular pattern along the disc margin, with features of typical entry and exit of retinal vessels on the optic nerve head and exceptionally good vision in the involved eye with old traumatic retinal detachment in the other, in a young Indian girl is described here for its rarity and indifferent clinical presentation. Various factors in its pathogenesis are postulated.     

Effect of treatment on pulmonary functions in chronic severe anaemia.

Pulmonary functions were measured in 15 patients with severe chronic anaemia (haemoglobin level < 5 g/dl). The measurements were repeated after correction of anaemia (Hb > 10 g/dl). Twenty age and sex matched, asymptomatic, non-smoker subjects served as controls. There was 80-100% improvement in various lung functions after correction of anaemia. Effort dependent parameters, viz FVC, ERV, IC, MVV were low in anaemic patients which improved with the rise of haemoglobin. The TLCO, DM, VC, KCO were not significantly influenced during anaemic state. FEV1, PEFR, RV/TLC were essentially normal. We conclude that the observed changes produced in lung functions during anaemic state are fully reversible after its correction.
