Mycoplasma synoviae (MS) obtained from broiler chickens condemned for airsacculitis was used to determine the influence of air temperature and relative humidity on the severity of airsacculitis produced experimentally. Infectious bronchitis virus was administered to 3-week-old broilers 5 days before aerosol exposure to MS broth cultures, producing extensive airsacculitis within 21-day study periods. High (31-32 C), medium (19-24 C), and low (7-10 C) air temperatures were studied in conjection with high (75-90%), medium (38-56%), and low (23-26%) relative humidities. Airsacculitis was most extensive (45%) at low temperatures regradless of high or medium humidity. The incidence of airsacculitis was greater (39%) at low humidity than at high humidity (17%) when air temperatures were medium. At high temperature, the trend was toward more airsacculitis (12%) at high humidity than (5%) at low humidity. However, the effect of cold air temperature was more dominant than the effect of relative humidity.

A study of chronic bronchitis was carried out on 195 ex-servicemen from Victoria New South Wales and Queensland. Exacerbations of chest symptoms were commonly found and chronic bronchitis was in important cause of haemoptysis. Weather conditions, especially cold weather, affected chest symptoms and early age of starting to smoke affected the incidence of severe bronchitis. The clinical profiles of the cases studied were similar to those in some of the reports from Canada and Britain.

The analysis of the haemodymanic responses and the behaviour of many "contractility indices" of the right ventricle -- after acute intravenous injection of large doses of acetil-digoxin, in twelve patients with CPC caused by COLD with predominant clinical signs of emphysema (group A) or bronchitis (group B) -- showed an alarming, although transient, increase of the average pulmonary pressure (PAP), accompanied by rise of pulmonary arteriolar resistanced (RAP), especially in patients of the first group. In these cases a slow and cautious digitalization is required. It furthermore suggested that such treatment should start only after an efficient restoration of ventilation, in order to allow a good response of the heart to cardiocynetic treatment.

57 cases of common cold, influenza, acute tonsillitis and acute bronchitis were treated by rapid needling with filiform needles at Dazhui (Du 14), Fengchi (GB 13), and Quchi (LI 11). The indices for observation were first determined, and the 19 cases that manifested an axilla temperature drop of over 1 degree C after treatment and a ratio of < 0.3 of the main symptom scores after treatment were regarded as markedly effective; the 27 cases that manifested an axilla temperature drop of 0.5-1.0 degree C and a symptom score ratio of 0.3-0.6 were regarded as effective, and the 11 cases that manifested an axilla temperature drop of < 0.5 degrees C and a symptom score ratio of > 0.7 were regarded as failures. The total effective rate was 80.7%. Analysis of the individual patients indicated that the peripheral blood leucocyte and lymphocyte counts differed insignificantly after needling, while the body temperature, rate of respiration, pulse, blood pressure and acupoint temperature all dropped, with a simultaneous increase in the percentage of T-lymphocytes. The immediate effects were especially marked in fevers due to exogenous wind and cold.

A girl of eight years fell ill with signs of common cold and bronchitis. Already on the second day of illness, before any treatment was started, she showed symptoms of a sicca-syndrome, beginning in the eyes, later the mouth. Ophthalmologic examination showed keratitis filiformis, histology of the salivary glands in the mucosa of the mouth was normal. Local substitution therapy led to subjective improvement. The disorder of secretion persisted for four months only, then rapid restitutio ad integrum of tears and saliva production occurred. Pathogenetically a parainfectious immunologic mechanism seems probable. During the observed period there were significant changes of antibody titers against RS-virus and streptococci, but it is not possible to identify the cause of the illness really. We conclude that a sicca-syndrome with normal histology of mouth-mucosa-glands is not necessarily prognostically infavorable.

Infections caused by Chlamydia pneumoniae were first described in 1985. The infection can cause common cold, sore throat, hoarseness, cough, headache, fatigue and sometimes influenza-like illness. Examination can indicate serous otitis media, sinusitis, laryngitis, bronchitis and pneumonia. The course can be long and relapsing. The recommended drugs for treatment are tetracycline or erythromycin for at least two weeks. Five verified cases are described in the article, four of them with symptoms from the upper respiratory tract only. It is concluded that Chlamydia pneumoniae is a not unusual cause of upper airway diseases. Up to now the diagnosis can best be verified by micro immunofluorescence. The authors call for a rapid and reliable test for use in physician's office. It is proposed that infections caused by Chlamydia pneumoniae be termed TWAR.

In the Munich Survey on Asthma and Allergy the parents of 9,349 fourth-class schoolchildren (mean age 9.8 years) in Munich and Southern Bavaria were addressed by a questionnaire to which 8,204 responded (87%). In 7,192 children (76%) a skin prick test was performed and 7,284 (77%) had pulmonary function tests with maximum expiratory flow-volume loops before and after cold air challenge. Of the 6,083 children of German nationality, 160 children (2.6%) had physician-diagnosed asthma, 79 (1.3%) so called asthmoid bronchitis and 373 children (6.1%) spastic bronchitis. Since physician-diagnosed diseases does not reflect all children with respiratory disease, symptoms reported in the questionnaire, results of skin prick and pulmonary function tests were combined to a score of probable asthma (VSA) with 9 items. Of the group with physician-diagnosed asthma, 79.4% of the children (127) have an elevated VSA, of 68.4% (54) of asthmoid bronchitis, 35.9% (134) of spastic bronchitis, 11.4% (192) of simple bronchitis and 3% of (114) never-diagnosed bronchial disease. The cumulative prevalence of asthma in ten-year-old children is therefore estimated at 10.2%. Only half of these children have been diagnosed with asthmatic disease.

A health survey was carried out among 8259 second- and fifth-grade schoolchildren living in three towns along the Israeli coast. The schoolchildren performed the following pulmonary function tests: forced vital capacity, forced expiratory volume in 1 sec, and peak expiratory flow, their parents filled out an American Thoracic Society-National Heart and Lung Institute health questionnaire. The aim of the survey was to study the impact of environmental and home exposures on the prevalence of respiratory conditions and on pulmonary function tests among Israeli schoolchildren. The health effects of exposure to passive smoking are discussed in detail. A trend of a higher frequency of reported respiratory conditions was found among schoolchildren whose fathers or mothers are smokers compared with children whose parents do not smoke. A statistically significant excess between 1.4% (for wheezing without cold) and 4.7% (for cough with cold) was found for children of smoking fathers; the excess for children of smoking mothers was between 1.6% (for wheezing with cold) and 3.6% (for cough with cold) compared with children of nonsmokers. A gradual excess in symptoms was found among children with none, one, and two smoking parents. Relative risks were found to be between 1.13 (for bronchitis) and 1.28 (for wheezing without cold) for children of smoking fathers, and between 1.24 (for asthma) and 1.41 (for cough with sputum) for children of smoking mothers, compared with 1.00 for children of nonsmokers. There was no consistent trend of reduced pulmonary function tests among children of smokers compared with nonsmokers' children.

Nasopharyngeal aspirates were obtained on admission from 614 patients younger than 2 years of age who were hospitalized in a ward for acute respiratory infections from June 1988 through October, 1989, in Santiago, Chile. Patients in two rooms were followed during the cold seasons by sampling aspirates every other day during the child's entire hospital stay. Clinical features were recorded daily. Indirect monoclonal immunofluorescent assay and isolation in HEp-2 were used for respiratory syncytial virus (RSV) diagnosis. The mean RSV detection rate was 39% at the time of admission, ranging from 8% in April, 1989, to 62% in July, 1988. During the cold months 43 of 288 (15%) nosocomial RSV cases were detected. Pneumonia and wheezing bronchitis were the principal diagnoses of both groups admitted, whether they were shedding RSV or not. It is concluded that RSV plays a major role in admissions for acute respiratory infections, as well as in nosocomial infections, in Santiago. Because clinical features do not allow one to differentiate viral from bacterial acute respiratory infections, the importance of rapid viral diagnosis is emphasized.

During 9 months (from January 1988 to September 1988), we experienced 82 patients (94 episodes) of respiratory infections with Branhamella catarrhalis in 5 different hospitals. There were 11 patients of acute bronchitis, 8 patients of pneumonia, 56 patients of chronic bronchitis (68 episodes), 3 patients of bronchiectasis, 3 patients of bronchial asthma with infection and chronic pulmonary emphysema in one patient. Ten cases of acute bronchitis and 3 cases of pneumonia had a recent history of common cold, with no underlying disease. There were 68 episodes of acute exacerbation of chronic bronchitis, the highest among 94 episodes of all respiratory infection. In chronic bronchitis the single pathogen B. catarrhalis was more than B. catarrhalis associated with other pathogens. H. influenza was associated with B. catarrhalis in in most cases of polymicrobial infection. beta-lactamase producing B. catarrhalis was 71% and oral penicillin was not effective in 8 cases of infection by beta-lactamase producing strains. These results show that B. catarrhalis is very important as a common pathogen of respiratory infection.
