The tussive and bronchoconstrictive effects of histamine inhalation in 7 normals, 7 asthmatics, and 24 patients with chronic cough (PCC) were measured by counting coughs during a standard histamine inhalation challenge. All PCC had a tussive response. Fifteen PCC exhibited significant linear correlations between cough count and either the change in forced expiratory volume at 1.0 (delta FEV1) or conductance-volume ratio (sGaw) (delta sGaw). Normals and asthmatics had little or no cough. Metaproterenol pretreatment in seven PCC reduced both the FEV1 and cough response to histamine without changing the relationship between cough and delta FEV1. The tussive and bronchoconstrictive effects of methacholine inhalation were also measured in 7 asthmatics and 16 PCC. One asthmatic coughed. Fifteen PCC coughed. There were significant linear correlations between cough count and delta FEV1 or delta sGaw in 10 PCC. At comparable delta FEV1 and delta sGaw, histamine produced more cough than methacholine. These data indicate that during inhalation of histamine or methacholine by PCC cough is related to, and may be caused by, bronchoconstriction. Histamine also causes cough by an additional mechanism not related to bronchoconstriction.

One hundred and thirty out-patients, affected by acute and chronic cough caused by upper respiratory tract inflammation, took part in two clinical studies aimed at evaluating the efficacy and tolerability of glaucine , a new antitussive agent. The first study involved 90 patients in a double-blind comparative trial of glaucine and codeine: both treatments were administered as a syrup at a dosage of 30 mg 3-times daily for 7 days. The cough suppressant effect of the two treatments was checked by the physician and the patient using a 4-point scale (from absent to severe), and by the patient using a visual analogue scale. Mean scores of the physician's evaluation decreased from 3.0 to 1.10 after codeine and from 3.0 to 0.47 after glaucine (p less than 0.001 between treatments). Mean values of the patients' visual analogue scales decreased from 83 mm to 17 mm after codeine, and from 85 mm to 7 mm after glaucine (p less than 0.001 between treatments). Constipation and nausea were reported by 9 patients on codeine and by no patient on glaucine (p less than 0.01). One patient on codeine was withdrawn from the study after 3 days because of vomiting, constipation and nausea. The second study was an open trial in 40 patients who received glaucine capsules at a dosage of 30 mg 3-times daily for 28 days. The antitussive effect of the treatment was evaluated on the basis of the same criteria as in the first study. The mean score of the physician's evaluation decreased from 3.0 to 0.15 (p less than 0.001); the mean value of the patients' visual analogue scales decreased from 93 mm to 1 mm (p less than 0.001).(ABSTRACT TRUNCATED AT 250 WORDS)

Twenty-four inpatients affected by chronic cough completed a single-dose double-blind cross-over study of placebo, glaucine 30 mg and dextromethorphan 30 mg. The study was carried out using a balanced incomplete block design, each patient receiving two of the three experimental treatments. Objective evaluation of cough was ensured by means of a writing cough recorder. Coughs after dextromethorphan and glaucine were fewer than coughs after placebo: however only glaucine was significantly different from placebo in reducing coughs. Treatments were well tolerated: clinical results included a reduction in pulse rate after both dextromethorphan and glaucine , and a large number of patients reporting side effects after dextromethorphan administration.

The effects of terbutaline sulphate were studied in 30 patients who presented with chronic cough at an allergy clinic. After a three week baseline period terbutaline and its placebo were given for two periods of three weeks each in a randomised, double blind, crossover manner. Patients kept a daily record of day and night cough scores and peak expiratory flow readings. Twenty one patients responded to terbutaline; placebo produced no significant effect. Both day and night cough scores (p less than 0.001) and peak expiratory flow rates were significantly improved (p less than 0.05) by the end of the first week of treatment with terbutaline. This improvement was achieved with only a fairly small change in airway calibre.

During a 5 months' period from January to May 1981 faecal samples of 176 donkeys from 59 herds all over the country were examined at the Institute of internal medicine, The Royal Veterinary and Agricultural University, Copenhagen. In addition, the investigation also included 106 horses from 30 of the donkey herds and 34 horses hospitalized with symptoms of dyspnoea and chronic coughing. In all, 87.5% of the donkeys were shown to excrete D. arnfieldi larvae, often in very high numbers, and the larval excretion was the only symptom of lungworm infection. There was no significant correlation between larval excretion and age, sex or herd size. In horses, the frequency of D. arnfieldi infection was approximately the same in the horses from donkey herds and in horses hospitalized due to chronic cough (10.4% and 8.8% resp.). In contrast to the donkeys, the infection in horses was always accompanied by dyspnoea and coughing.

Sixty female patients with clinically demonstrable stress incontinence of urine have had a Stamey operation during the last 3 years. The results have been good in curing stress incontinence, whilst the majority of the failures have been in patients with severe detrusor instability or a chronic cough. There have been few post-operative complications and urodynamic studies have shown improved cough urethral profiles and no evidence of bladder outflow obstruction. The Stamey procedure can be recommended as the initial operation for surgically curable incontinence. Mild bladder instability is not a contraindication to the operation and it is also useful in elderly, unfit or obese patients.

Thirty-eight patients, affected by chronic cough and hospitalized in 14 different rooms, entered a double-blind cross-over trial aimed at evaluating efficacy and tolerance of single oral doses of glaucine (eo mg) versus single oral doses of codeine (30 mg) and placebo. Patients occupying the same room were administered on 3 consecutive nights, and an objective evaluation of efficacy was ensured by means of a tape recorded. The mean cough counts during the 8-h interval after drug administration were 269.3 after placebo, 241.8 after glaucine, and 201.9 after codeine (p less than 0.05). The antitussive effects of glaucine and codeine were practically superimposable up to the 6th h, when glaucine effect declined. Treatments were well tolerated by all the patients, they themselves were not able to detect any difference in cough suppression among the three treatments.

Standardized respiratory disease questionnaires (ATS-DLD-78) were administered to 5,686 adult women. Risk factors were evaluated by logistic analysis that adjusted for multiple potential confounding factors. Among current smokers, the number of cigarettes smoked per day was consistently the strongest risk factor for chronic cough, chronic phlegm, wheeze, and dyspnea. The odds ratios for these symptoms in a smoker of 25 or more cigarettes per day relative to a smoker of 1--14 cigarettes per day were 4.74, 4.21, 2.05, and 3.71, respectively. Ex-smokers showed risks between those of current and never smokers. Cigarette tar content was a significant independent risk factor for chronic cough (p = 0.005) and of borderline significance for chronic phlegm (p = 0.077). High tar cigarette smokers in this population (average, 22 mg) had an odds ratio of 2.01 for chronic cough and 1.59 for chronic phlegm relative to low tar cigarette smokers (average, 7 mg). The effect of cigarette tar was linear and independent of cigarettes smoked per day. Smoke inhalation was a significant risk factor for chronic cough (p = 0.029) and for chronic phlegm (p = 0.038). Tar content and smoke inhalation were not significant risk factors for wheeze or dyspnea. Cigarette particulate content (tar) appears to be causally linked to cough and phlegm production., but the association of cigarette smoking and symptoms of wheeze and dyspnea may be more strongly related to the vapor phase of cigarette smoke.

To determine how frequently bronchoscopic examination and pulmonary function testing are useful in establishing a diagnosis in patients with chronic cough as an isolated clinical symptom, we reviewed the records of all patients referred to pulmonary specialists at 3 community hospitals for evaluation of cough over a 6-yr period. There were 109 patients with the isolated symptom of chronic cough and a normal or stable chest roentgenogram. Bronchoscopy was performed in 51. All patients but 1 were followed until the cough disappeared or for a minimum of 1 yr. Carcinoma was established as the cause for cough in 1 patient. Spirometry and/or bronchial inhalation challenge was performed in 87 patients. Previously undiagnosed asthma was discovered in 39 patients by these means. Pulmonary function testing has diagnostic value in this population, but bronchoscopy is of limited value in determining the cause of isolated chronic cough.

All the Tahitian school children from 3rd to final grade were questioned by an auto-questionnaire in May 1979. 93% replied to the questions asked (3,870). The prevalence of upper respiratory infections was increased as well as broncho-pulmonary symptoms (cough or other lung disease) during the year under study when compared to a control group in Metropolitan France. This prevalence was significantly increased both in boys and girls who smoked. The incidence of frequent or chronic cough was most increased in the older pupils, boarders, those followed a technical curriculum and belonging to the lower socio-professional categories. Asthma was very frequent at 11.5%, had an equal sex incidence and was not linked to any identifiable factor--the same enquiry was done in the Bas-Rhin department in France 3 years before; Tahitian school children, in general, have double the incidence of respiratory disease that is found in the Bas-Rhin.
