A double-blind cross-over trial was carried out to evaluate the antitussive activity of viminol p-hydroxybenzoate; the comparison was done with three preparations: a placebo and the drug at two doses, 70 and 140 mg respectively. The responses were scored hourly up to 4 hours after the administration of single doses in the morning to subjects with persistent cough. The highest dose of viminol showed a definite antitussive activity, whereas the lowest did not differ from the placebo. The antitussive effect appears clinically useful for the treatment of cough, but further studies are indicated to define optimal dosage schedules.

The effect of intravenous lidocaine in the treatment of persistent cough occurring after diagnostic bronchoscopies performed under general anaesthesia was investigated in a controlled clinical trial. The study comprised 28 adults patients, all of whom had regained consciousness after anaesthesia. Fifteen patients were treated with lidocaine (1.05 mg/kg body weight) and 13 patients with placebo (saline). In each patient the intravenously injected dose was repeated once after 5 min. In 11 of the 15 patients (73%) who received lidocaine coughing ceased, while it continued in all 13 patients in the placebo group. The difference is highly significant (P less than 0.001). None of the patients developed side effects such as hypotension, arrhythmias, central nervous system symptoms or respiratory depression after injection of lidocaine. It is therefore concluded that intravenous lidocaine in man is a safe and useful cough-suppressant.

The primary purpose of sputum cytology is to detect preinvasive and invasive malignancy. Candidates for the screening procedure include long-time smokers with productive cough, patients chronically exposed to asbestos, patients with hemoptysis, persistent cough and/or weight loss, and asymptomatic patients with x-ray lesions or unexplained pleural effusions. The procedure is inexpensive and highly diagnostic. Five consecutive specimens produced by deep coughing are required for adequate evaluation.

A chronic persistent cough is one that lasts longer than eight weeks in a patient without known chronic pulmonary disease. These patients may experience prolonged frustration, guilt and self-imposed social isolation, besides risking the medical and surgical complications of recurrent coughing episodes, if the cause of their cough is not quickly established and treated. A comprehensive discussion of the management approach to this problem with reference to the recent literature is presented.

The case of a 10.5-year-old girl, who was diagnosed with a case of thalassemia major at the age of 8 months and had been on regular blood transfusions since then, is related. Donor screening for HIV was started in mid-1988, thus she had received unscreened blood for a number of years. In February 1991, she presented with a dry persistent cough, moderate grade continuous fever, and breathlessness on exertion for over 2 weeks. Chest X-ray showed bilateral infiltrations. She was put on penicillin and chloramphenicol with a provisional diagnosis of bronchopneumonia. In March 1991, she had to be hospitalized for impending respiratory failure. After treatment with intravenous fluids and parenteral antimicrobials, her condition stabilized and she was discharged. In April 1991, she was readmitted because of complaints of difficulty in swallowing and weight loss. Her chest signs had persisted and she had developed oropharyngeal candidiasis with ulcerations. She also had alopecia, a generalized lymphadenopathy, digital clubbing, and bilateral parotid enlargement. Candidiasis responded to vigorous therapy with clotrimazole. Fine needle aspiration of lymph node showed a reactive hyperplasia. HIV antibodies were detected in the serum with ELISA and confirmed by Western blot. Immunologic tests showed evidence of severe immunodeficiency. The Multitest CMI, which simultaneously tests delayed skin hypersensitivity to seven common recall antigens, was totally nonreactive. She was classified as having AIDS according to World Health Organization criteria for children under 13 years of age. The diagnosis of lymphocytic interstitial pneumonitis (LIP) was also made based on the symptoms. Oral prednisolone was given 2 mg/kg/day in 3 divided doses for a month. The cough and dyspnea showed great improvement and the parotid swellings disappeared; lymphadenopathy, clubbing, and alopecia, however, persisted. The child was kept on maintenance therapy of prednisolone and on alternate day co-trimoxazole for prophylaxis against Pneumocystis carinii infection.

In order to tackle the problems of underdiagnosis and undertreatment of asthma in childhood general practitioners need to be aware of which children in their practices have or might have asthma. In an effort to identify a cohort of asthmatic or potentially asthmatic children a trained audit facilitator studied all the medical records of children aged between one year and 15 years who were registered with 12 Tayside general practices. From a total of 10,685 medical records the frequency of 'key items' sometimes associated with asthma were as follows: one or more episodes of bronchospasm or wheeze 23.7% of children, persistent cough 23.2%, treatment with anti-asthma therapy in the past 20.0%, exercise induced cough or wheeze 5.2% and history of 'wheezy bronchitis' 4.6%. However, in only 896 children (8.4%) had a formal diagnosis of asthma been made. Of all the children, 5.4% had received a prescription for anti-asthma medication within the past three months. Only 1.2% were taking an inhaled corticosteroid and 1.0% sodium cromoglycate, but many more were taking inhaled bronchodilators (3.1%) and oral bronchodilators (1.7%). The findings suggest that a systematic review of medical records by a trained facilitator can identify those children who could benefit from clinical review. Practices who wish to know which of their children have or might have asthma should consider using medical record review to search for key items associated with asthma.

The Indo-Dutch Environmental and Sanitary Engineering Project under Ganga action Plan in Kanpur and Mirzapur is being executed within the framework of Indo-Dutch bilateral development cooperation. The project aims to integrate technological, social and health related improvements. It is expected that the development approach and methodology can be replicated in other urban settlements in India. The project is being supplemented by a training and institutional strengthening programme, which will facilitate the transfer of new technologies and improvements in operation and maintenance of these new technologies. One of the project's goals is to improve living conditions in the targeted areas by installing drinking water and drainage systems. A socio-economic unit (SEU) in the project supports these technical interventions by encouraging the community to participate in project activities. The Occupational Health Programme in Mirzapur was conceived by the SEU to improve the health and living conditions of child and adult weavers. At the start of the programme, 200 weavers and 60 non-weaver workers from Mirzapur city, matched for age and socio-economic status, were interviewed and underwent a physical examination. The mean age of the weavers is 27 years, reflecting the relatively large percentage of child labour (13.5%). Illiteracy among them is 73%, whereas 14% have had only a primary education. 64.5% of the carpet weavers are Muslims and 35.6% are Hindus. 61% own a loom or work in a family owned loom shed. 95% of the weavers have a monthly income of less than 600 Rs. Complaints of a persistent cough and cough with expectoration, backache, the common cold and joint pains occurred more often in the weaver population than in the comparison group and have been identified as 'occupational hazards'. An intervention programme has been implemented based on the results of the occupational health survey. These interventions include awareness camps, installment of plexiglass tiles for light improvement in the loom sheds, training of community health volunteers and house-to-house health education. Another essential part of the programme is the provision of functional literacy classes for child and adult labourers in the carpet weaving industry. Occupational health as an entry point proved to be a successful approach in this segment of the informal sector, where child labour plays an important role.

Cough is a powerful physiological reflex mechanism that causes central airways to be cleared of foreign material and excess secretions. Chronic cough is a very common presenting symptom in general practice with a prevalence in the population of about 5%. As a general rule, persistent cough represents organic disease of the upper and lower airways, the lung parenchyma, the pulmonary circulation, the pleural space, the mediastinum and the upper gastro-intestinal tract. The most common cause is cigarette smoking, but virtually any chronic lung disease may be occasionally associated with cough. Complications of coughing are tussive syncopes, rib fractures, rupture of respiratory muscles and eventually hernias. Based on a detailed clinical history and physical examination, the investigation includes a chest radiograph, spirometry, and sputum smears. Radiography of the sinuses, bronchoscopy and upper gastro-intestinal endoscopy may be added. If the treatment of an underlying disease is successful, chronic cough may disappear. There are few 'antitussive' drugs with proven suppression of the cough reflex.

Unexplained chronic persistent cough has been shown to be associated with increased episodes of otherwise asymptomatic gastroesophageal reflux; however, normal subjects without cough also exhibit some reflux. We postulate that the prompt clearance of refluxed acid from the esophagus may play an important role in the prevention of cough, and we sought to determine if patients with chronic cough have impaired clearance. Thirty patients with unexplained chronic cough underwent 24-h ambulatory esophageal pH monitoring. Compared to 12 matched control subjects, patients experienced significantly more episodes (all values expressed as median [range]) of reflux per 24 h (88.3 [5.0 to 338.0] vs 5.7 [0 to 13.0]; p < 0.0001) and had impaired clearance of esophageal acid as measured by the duration of individual reflux episodes (3.0 [0.1 to 20.5] min per reflux vs 0.7 [0 to 2.5] min per reflux; p < 0.01). We conclude that patients with chronic persistent cough have impaired clearance of esophageal acid.

The clinical effects of inhaled ipratropium bromide were studied in 14 non-smoking patients with persistent post-viral infective cough employing a controlled double-blind, cross-over trial. Patients were selected if they demonstrated no apparent underlying cause for their persistent cough after appropriate radiological and respiratory function tests including methacholine reactivity and bronchoscopic examination. Inhaled ipratropium bromide (320 micrograms day-1) produced significantly less day and night time cough (P < 0.05) with overall clinical improvement in 12 cases, five of whom had total resolution of their cough. We conclude that ipratropium bromide is an effective treatment in non-smoking adults with protracted cough following clinical upper respiratory tract infection.
