A prospective study of respiratory infections was performed in nineteen married asthmatics and their normal spouses who were examined at monthly intervals during a 1-year period. The colds described were associated with nasal symptoms, sore throat and usually malaise, fever, cough and hoarseness. The asthamtics reported a larger number of these symptomatic episodes than the non-asthmatics but significantly fewer of the episodes in the asthmatics were objectively confirmed by viral isolation or rise in serum titre of viral antibody. The frequency of respiratory infections was not influenced by the long term use of inhaled beclomethasone dipropionate and oral corticosteroid drugs. Less than 10% of the exacerbations of asthma were associated with respiratory infection. The disability resulting from respiratory infections in the asthmatics did not significantly exceed that in the non-asthmatics.

A 40-year-old woman who had recently undergone kidney transplantation was succesfully treated for diffuse influenza virus pneumonia. The illness was acute, with rapid onset, high fever, nonproductive cough, dyspnea, cyanosis, crepitations and rales over both lung bases, and associated arterial hypoxemia, leukopenia, and thrombocytopenia. Prophylactic use of antibiotics to prevent superimposed bacterial infection and reduction of immunosuppressive therapy to minimal dosage during the critical phase of the respiratory infection contributed to the patient's survival. An episode of graft rejection was reversed by resumption of immunosuppressive therapy at standard dosage levels.

Gastroesophageal reflux is the commonest esophageal cause of chronic intermittent aspiration. The authors investigated 1000 consecutive patients with reflux with reference to their medical history, and by barium esophagography, esophageal manometry and pH studies. In patients with respiratory complications, chest roentgenography and pulmonary function tests were also performed. Of the total number, 279 patients aspirated either by coughing and choking during swallowing or as a result of night reflux; of these, 159 had associated respiratory symptoms, which included cough, voice change, recurrent respiratory infection, bronchiectasis and asthma. Of the patients with aspiration, 120 had surgical correction of reflux because conservative management failed. This form of reflux control improved the symptoms of cough and voice change and the condition of patients with recurrent infections or bronchiectasis, but alleviated the symptoms in only 8 of 28 asthmatic persons.

In 276 children admitted to hospital with febrile convulsions a wide range of virus types was identified by means of nasopharyngeal secretions and cough/nasal swabs. The overall virus identification rate was 49%. Analysis of age, sex, family history, and past history showed no marked differences between the virus-positive and the virus-negative children. More than 80% had symptoms of respiratory infection in association with their convulsions, whether or not a virus was identified. Convulsions were not apparently more severe in the virus-positive group. Rapid virus diagnosis was found helpful in the management of children with febrile convulsions. The virus aetiology of many febrile convulsions has implications both for hospital cross-infection and for research into methods of prevention.

In the winter of 1972-1973 a multicentre trial of the treatment of upper and lower respiratory tract infections was carried out in Spain using doxycycline. 85 physicians participated in the study and treated 1,653 patients. The infections included acute bronchitis, acute exacerbation of chronic bronchitis, pneumonia, bronchopneumonia, tonsillitis, pharyngitis, trachetis, sinusitis, and otitis media. The majority of the patients were adult out-patients although some children and adolescents were included: 1,011 of the patients were male and 642 female. A number of the signs of respiratory infection such as temperature, cough, pain and inflammatory symptoms were examined. A rapid reduction in intensity and severity was noted in all of these parameters. Tolerance to the antibiotic was excellent. Only minor side-effects were reported and these were mild and mainly limited to the gastro-intestinal tract - in no case was treatment discontinued. The total number of side-effects was 37; they occurred in 31 out of the 1,653 patients. The overall evaluation of results showed a very good or good response in 85% of the patients. It appears from this multicentre study that the efficacy of doxycycline has in no way decreased over the 7 years of its extensive use in Spain. It remains a fast acting and effective antibiotic in upper and lower respiratory tract infections irrespective of age, sex or diagnosis.

Chronic cough may be the sole presenting manifestation of bronchial asthma (reference 3; Corrao et al, 1979), and "cough variant asthma (CVA)" has been used to categorize such patients. In order to clarify the clinical picture of CVA, we evaluated the clinical history, laboratory data, sputum cytology and pulmonary function in 14 subjects (5 males and 9 females, aged 14 to 65 years) compatible with the following diagnostic criteria: (1) chronic cough persistent for more than 8 weeks, (2) no wheeze nor dyspnea, (3) no rales, (4) no past history of asthma, (5) bronchial hyperreactivity to methacholine proven by Takishima's method (reference 13), (6) effectiveness of bronchodilators against cough, (7) normal chest X-ray film, (8) afebrile and negative CRP, (9) absence of sinusitis and postnasal drip, or if present, they are proved not to be responsible for the cough, and (10) no other causes of cough such as heart disease, prescription of ACE inhibitors, current smoking. The results were as follows. 1) Many of the subjects were atopic, with positive skin tests to one or more common allergens in 10 subjects, elevated serum IgE in 4 subjects, and past history and family history of atopy in 4 and 7 subjects, respectively. 2) Respiratory infection preceded the onset of CVA in 3 subjects. 3) Cough was generally nocturnal, but 2 subjects coughed only in the daytime. 4) FEV1.0% was decreased (less than 70%) in only 2 subjects, whereas V25 was decreased (less than 80% of predicted value) in 11 out of 12 evaluable subjects, which suggested peripheral airway obstruction.(ABSTRACT TRUNCATED AT 250 WORDS)

Two patients of unusual cough related stress fractures of the ribs are presented. Both patients complained of cough and chest pain with respiratory infection, and the initial chest radiographs showed only an infiltrative shadow due to bronchopneumonia in the lung field, however, failed to reveal any definite osseous abnormality of the ribs. Follow up chest radiographs revealed a callus formation in the fracture sites. In both patients, fracture sites were multiple and located at the axillary line, and radionuclide bone scan disclosed focal abnormal concentrations of activity in these characteristic locations of the lesions. Moreover, there were abnormal accumulation sites in the adjacent above and below ribs, and this finding also seemed to be characteristic of cough related stress fractures of the ribs.

The effectiveness of continuous compared with intermittent amoxicillin prophylaxis administered to subjects with a history of recurrent otitis media enrolled during the winter respiratory infection season was assessed in a prospective single blinded clinical trial. Patients with three or more chart-documented episodes of otitis media (OM) in the preceding 6 months were enrolled and randomly assigned to each treatment group. Patients in the continuous group received amoxicillin twice a day every day for up to 4 months. During the same period patients in the intermittent group received amoxicillin twice a day only when they developed respiratory symptoms of congestion, runny nose or cough. Among the 30 patients receiving continuous amoxicillin who were followed for at least 3 months, 22 (73%) had no OM episodes and 8 (28%) had one OM episode. Among the 25 patients receiving intermittent amoxicillin for at least 3 months, 13 (52%) had no OM episodes, 8 (32%) had 1 episode and 4 (16%) had 2 episodes. Significantly fewer patients had fewer than 2 OM episodes on continuous compared with intermittent amoxicillin (P less than 0.04). The incidence density was 0.46 episode/120 days at risk in the continuous treatment group compared with 1.10 episodes/120 days at risk for intermittent treatment (P less than 0.03). Among patients 12 months or older the incidence density of OM episodes per 120 days was 3.5 times higher in the intermittent amoxicillin group (0.80) compared with the continuous amoxicillin group (0.23) (P = 0.05). The incidence densities of the continuous vs. intermittent therapy groups did not differ significantly for patients younger than 12 months of age. The findings suggest that continuous amoxicillin prophylaxis may be more effective than intermittent treatment in preventing OM episodes in patients 12 months or older with a history of recurrent otitis media.

The purpose of this study was to ascertain whether in patients with persistent cough the presence of bronchial hyperresponsiveness (BH) and development of asthma could be speculated based on clinical data. Only patients who met strict criteria excluding exogenous factors that influence BH, especially smoking or respiratory infection, were included in this study. The study group included 15 males and 50 females aged 18 to 62 years (mean +/- S.D. of 44 +/- 12 years) whose physical findings, chest X-rays, spirometry results and peripheral leukocyte counts were within normal limits. Duration of cough was at least one month. The patients had no history of wheezing, dyspnea or previous bronchodilator therapy. None of them had ever been smokers. In addition, there was no history of upper respiratory tract infection in the preceding month. BH was assessed by "Astograph" using methacholine. Cmin and Dmir or SGrs/Grs cont. were measured as the indexes of bronchial sensitivity or reactivity respectively. A methacholine Cmin of 3, 125 micrograms/ml or less was taken as a positive indication of BH. The evaluated clinical data were age, pulmonary function (spirogram or flow volume curve), atopic factors (serum total IgE and family or personal history of atopic diseases), peripheral eosinophil count, bronchial sensitivity or reactivity, and clinical features of cough (induction by exercise or cold air and nocturnal worsening). The results were as follows. (1) Twenty-nine (45%) of 65 patients were BH-positive (BH-positive group). (2) There was no significant difference in age, %FVC, IgE, and family or personal history of atopic diseases between the BH-positive and negative group. However, the BH-positive group had significantly lower FEV1.0%, %FEV1.0, PEFR, (p less than 0.05) and V25/H (p less than 0.01) and a higher peripheral eosinophil count (p less than 0.05) than the BH-negative group. (3) Seventeen (85%) of 20 BH-positive patients prescribed bronchodilators (beta 2 agonist/theophylline) responded to therapy within a month. (4) Seven (29%) of 24 BH-positive patients available for 2 years follow-up developed clinical asthma. (5) There was no significant difference in %FVC, FEV1.0%, V25/H and peripheral eosinophil count between the patients who developed asthma (Group A) and those who did not (Group N-A). However, The patients in Group A were older than those in Group N-A.(ABSTRACT TRUNCATED AT 400 WORDS)

A cross sectional study was carried out to determine the prevalence of bronchial hyperresponsiveness and asthma in 3067 students aged 11-17 years in an urban and a rural area of Guangzhou (Canton), China. The methods used included a self administered questionnaire, a histamine bronchial provocation test, and allergen skinprick tests. Bronchial hyperresponsiveness was defined as a 20% fall in FEV1 and peak expiratory flow at a provoking dose of histamine (PD20) less than 7.8 mumol on two occasions four weeks apart. The response rate was 98.0% and 99.2% in the two areas. The prevalence of bronchial hyperresponsiveness was 4.1% and of diagnosed asthma 2.4% in the total population. There were no significant differences in prevalence between the urban and the rural area or between boys and girls. The 11-12 year group had a higher prevalence of bronchial hyperresponsiveness (7.6%) than the older groups. Of the 125 with bronchial hyperresponsiveness, 12.0% were defined as having severe or moderate (PD20 less than 0.8 mumol), 26% mild (0.9-3.2 mumol), and 62% slight bronchial hyperresponsiveness (3.3-7.8 mumol). The severity of bronchial hyperresponsiveness was closely related to diagnosed asthma, wheezing, and cough, though half the students with bronchial hyperresponsiveness were symptom free. The most common allergens were house dust and house dust mite in the city, and hay dust, pollen, and feathers in the rural area. The odds ratios for having respectively slight, mild or moderate, and severe bronchial hyperresponsiveness were 5.9, 21.0, and 30.4 for atopy; 1.9, 1.9, and 7.3 for early respiratory infection; and 3.1, 2.5, and 5.6 for a history of parental asthma.
