Comparison of bronchodilatation produced by an anticholinergic (ipratropium bromide), a beta-2 adrenergic (fenoterol) and their combination in patients with chronic obstructive airway disease. An open trial.

Fenoterol hydrobromide (200 micrograms), ipratropium bromide (40 micrograms) and a combination of the two in the same dosage were administered by metered dose inhaler on 3 separate days to 20 patients with chronic bronchitis and emphysema. On each day, baseline forced vital capacity (FVC), forced expiratory volume in one second (FEV1), peak expiratory flow rate (PEFR) and mid maximum flow rate (MMFR) were recorded. The values were again recorded after administration of the drug at 15, 30, 45 and 60 minutes. Side effects if any were recorded. There was a significant increase from baseline in FVC and FEV1 with all the three regimens at 15, 30 and 45 minutes. However, the rise in MMFR was significant only with ipratropium bromide and the combination regimen. At 60 minutes, the rise in FVC, FEV1 and MMFR was significant only with the combination regimen. There was no significant change in the PEFR values at any time with any drug. The difference in rise in all the four parameters with the 3 regimens was not statistically significant. No side effects were noted. Thus, a combination fenoterol and ipratropium bromide produced a more prolonged bronchodilatation, and ipratropium bromide perhaps acts both in the major (indicated by rise in FEV1) and small airways (measured by MMFR).

Blood carboxyhaemoglobin levels in smokers of Indian cigarettes with and without filters.

Blood carboxyhaemoglobin levels showed no significant difference between smokers of Indian cigarettes with and without filters (14.66 +/- 1.85 vs 16.07 +/- 1.92%; p greater than 0.05), although the value was slightly lower in the former. This may be because filters do not provide protection against absorption of carbon monoxide in the smoke. Further study in a large number is required.

Fiberoptic bronchoendoscopic examination in patients with haemoptysis and normal chest roentgenogram.

The role of flexible fiberoptic bronchoendoscopic (FOB) examination was evaluated in a retrospective analysis in 155 patients with unexplained haemoptysis and normal chest skiagrams. The procedure was helpful in reaching a specific diagnosis in 11 (7.1%) patients, 4 of whom revealed mycobacteria in bronchial secretions and 7 had neoplastic lesions. In another 68 (43.9%) cases only non-specific findings like inflammation were found, but the site of abnormality could be localized. We recommend the use of FOB in the routine assessment of haemoptysis.

Wegener's granulomatosis in north India. An analysis of eleven patients.

Eleven patients with Wegener's granulomatosis were seen at this Institute over a period of 20 years. There were six men and five women. The average age of presentation was 38.3 years, and the mean duration of symptoms was 10.5 months. Constitutional symptoms (82%), cough (82%), ocular symptoms (64%), arthralgias (55%), rhinorrhoea (55%), haemoptysis (45%), nasal granuloma (45%), otorrhoea (36%), sinusitis (36%), skin lesions (27%), and renal failure (27%) were the clinical manifestations encountered. All patients had an elevated ESR, and 55% had leucocytosis. Proteinuria and haematuria were observed in 64% and 55% respectively. Chest radiographs were abnormal in 82%. In four patients the disease had a fulminant course and the patients died before adequate treatment was given. Two patients received corticosteroids alone and have since been lost to follow up. Five (45%) received adequate cytotoxic therapy and have done well for 8-46 months (mean, 24.8 months) after diagnosis. Wegener's granulomatosis in India is apparently similar to that seen elsewhere, but the high incidence of tuberculosis interferes with early diagnosis and treatment.

Tuberculous pleural effusion and lymphadenitis treated with rifampin-containing regimen.

Rifampin, isoniazid, and ethambutol were administered in single daily dose for nine months to 91 patients with pleural effusion and 45 patients with lymphadenitis, both of tuberculous etiology. Clinical and roentgenographic clearance of pleural effusion was successfully achieved in all cases at the end of nine months of treatment. Followup of 80 cases of pleural effusion up to nine months, in 55 cases up to one year, and up to two years in 30 cases after completion of therapy, showed no recurrence. In the cases of tuberculous lymphadenitis, resolution of lymph nodes occurred in 31 cases (68.8 percent) at the end of nine months of treatment. Therapy had to be extended for varying periods for achieving successful response, and in five cases, medical treatment had to be supplemented with surgical drainage and excision of the nodes. Short course chemotherapy can be used to treat pleural effusion, but the same mode of treatment is less effective for cases of tuberculous lymphadenitis.

Radioactive uranium in various Indian tobaccos and consumable products (snuff, chutta, bidi and cigarette).

Tobacco is chewed in the form of snuff and thus its radioactivity--if there is any--goes directly into the body. Besides normal smoking, tobacco is also smoked in reverse manner in the form of "chutta", an indigenously prepared cigar made from the home grown plants of Nicotinia tobacum in South East coastal towns and villages in India. The burnt residue and the radioactive element--if there is any--in the case of chutta smoking will also go directly in the body causing hazardous effects. Uranium traces were determined in commercially available samples of snuff, chutta, bidi and cigarette tobacco using radiation damage etch technique. The analysis showed that uranium levels varied from 7.4 to 19.1 ppm in snuff, 0.16 to 0.37 ppm in chutta, 0.13 to 0.23 in bidi and 0.037 to 0.12 ppm in cigarette tobacco.

Sarcoidosis in north India: the clinical profile of 40 patients.

Sarcoidosis is being increasingly recognized in India. Over the last 7 years we studied 40 patients. Older males out numbered young females. Thoracic (98%), constitutional (50%) and ocular (40%) involvement dominated the clinical profile. In addition, erythema nodosum (20%), facial palsy (13%), parotid enlargement (8%), lymphadenopathy (42%), hepatomegaly (37%) and splenomegaly (17%) were also observed. Radiologically, 53%, 30% and 15% of patients were in Stage I, II and III respectively at presentation. Kveim test was positive in 45% of those tested. The diagnosis was histologically confirmed in 80% of patients. The remaining eight patients (20%) were relatively asymptomatic, all had bilateral hilar lymphadenopathy and either erythema nodosum or uveitis or both. 88% were tuberculin negative. Systemic steroids were used in 60% and topical steroid eye drops in a further 20%. Response to therapy was excellent except in Stage III disease where radiological and spirometric deterioration was observed in three patients. There were no fatalities. The overall clinical behaviour of north Indian patients with sarcoidosis was quite similar to that of patients in England but different from previously reported Indian patients.

Clinical experience with short-course chemotherapy in patients with tubercular pleural effusion and lymphadenitis.

Twenty-one patients with pleural effusion and 27 patients with lymphadenitis, both tubercular in origin, were administered isoniazid, rifampicin and ethambutol in a daily single dose for 9 months. 100% response was seen in patients with pleural effusion. In the case of tuberculous lymphadenitis the therapeutic response was unsatisfactory, and complete resolution of lymph nodes was achieved in 16 out of 27 patients only (59%). Drug treatment had to be extended for another 3 months which gave 89% response. In view of our present findings, short-course chemotherapy appears not to be the ideal mode of treatment for tuberculous lymphadenitis. There were no side effects from drug therapy in either group of patients.
