Five cases of the respiratory infections, in which Neisseria meningitidis was isolated upon the examination of the transtracheal aspiration (TTA), were reported. Patients studied were four males at the ages of 18, 56, 66 and 78 years, and a 18-year old female. Five cases were bronchopneumonia (two cases), acute bronchitis (two cases) and diffuse panbronchiolitis (DPB) (one case). Underlying diseases were as follows: lung cancer or acute myocardial infarction in cases of bronchopneumonia, and interstitial pneumonia or pulmonary tuberculosis in cases of acute bronchitis. There was a case in which only N. meningitidis was cultured from specimens obtained by TTA, although another different organism, in addition to N. meningitidis, was recovered from the patient of other cases. Other organisms found together with N. miningitidis were H. influenzae (2 cases), S. dysgalactiae (1 case) and M. tuberculosis (1 case). Predisposing factors were common cold in the female patient and bronchoscopic examination in the cases of lung cancer and of interstitial pneumonia. Two of the five cases occurred consecutively in the same room and so they were considered as nosocomial infections. With these findings, it can be posturated that N. meningitidis might be one of the etiological agents of the respiratory infections.

In Germany approximately 5 per cent of the population suffer from asthma. The disease is characterized by nonspecific airway hyperresponsiveness to various stimuli, leading to airways obstruction. In the majority of cases sensitizations to inhaled or food allergens are revealed by skin tests and/or in-vitro tests (RAST) ("extrinsic" asthma). Due to an allergen-induced increase of non-specific airway hyperresponsiveness allergencontacts favor asthmatic symptoms after non-specific stimuli, such as cold air or exercise. Therefore diagnostic measures in asthma should include allergic history and standard allergen skin tests in each case. Nonspecific stimuli often play a predominant role among the causes of acute airways obstruction, depending on the degree of nonspecific hyperresponsiveness. Other cases of asthma are characterized by the absence of senzitizations ("intrinsic" asthma). Usually, the symptomatology of these cases is more severe than in extrinsic asthma. In most cases of allergic asthma prognosis is favourable, in contrast to chronic obstructive bronchitis and/or emphysema. The therapeutic approach consists of allergen avoidance and hyposensitization, if feasible, and of a combination of bronchodilating and antiinflammatory drugs. A number of work places has to be avoided. Drug treatment should aim at reducing airways hyperresponsiveness and absence of asthmatic symptoms, requiring (inhaled) steroids in most cases. Other therapeutic principles have to be considered, such as allergen avoidance, cessation of cigarette smoking, change of work place, choice of favourable climates during holidays, and hyposensitisation.

Nine cases of respiratory infections caused by syncytial respiratory virus which were diagnosed by direct immunofluorescence with monoclonal antibodies are presented here. Six of them have been clinically diagnosed as bronchiolitis and the remaining three are diagnosed as obstructive bronchitis, upper respiratory cold and respiratory distress respectively. Seven are male and two are female. Their ages vary from 13 days to eleven months. Its usefulness is indicated given its speed and the current availability of specific antiviral therapeutics. The test would be especially indicated in atypical cases like nursing babies with apnea or those with congenital heart disease or other underlying lung diseases and also to prevent intrahospital epidemias. The conclusion is reached that direct immunofluorescence seems to be an attractive alternative for laboratories that do not have costly cell culture equipment.

Mycoplasma pneumoniae is a pathogenic micro-organism frequently held responsible for acute respiratory infection. The disease is ubiquitous and often proceeds in epidemics among small communities of young people (families, army barracks, universities). Its usual clinical manifestations consist of a stubborn cough symptomatic of tracheo-bronchitis with or without fever, and inflammation of the upper respiratory tract. Cases where chest X-rays show a pulmonary infiltrate are less frequent, but they differ from other lung diseases in that the respiratory signs at physical examination are discreet. The presence of cold agglutinins is not specific, but it contributes to the diagnosis. Cutaneous, neuromeningeal, cardiovascular and osteo-articular manifestations are rare, usually delayed and of lesser importance. Diagnosis rests on positive cultures of tracheo-bronchial or pharyngeal samples and/or on a significant increase in the titers of serum antibodies directed against M. pneumoniae. The disease is usually benign. Antibiotic therapy with macrolides or tetracyclines shortens its duration and reduces the incidence of complications. The latter chiefly concern elderly subjects and patients with COLD for whom M. pneumoniae infection constitutes a major risk of respiratory failure.

Irwin and co-workers have designed an anatomic approach to the diagnosis and treatment of cough. In their hands, diagnosis was consistently determined and treatment successful almost without exception, if sustained. We reviewed the results of a similar approach in 139 consecutive and unselected patients referred to pulmonary specialists in two community hospitals. Thirty-nine patients demonstrated hyperreactive airways (HA) by carbachol inhalation and/or eucapnic hyperventilation of cold air. Twenty-seven of 78 without HA had postnasal drip, and 13 of 78 had a persistent cough following acute upper airway inflammation. Other less common diagnoses included chronic bronchitis, gastro-esophageal reflux, occupational bronchitis, interstitial lung disease, and psychologic causes. We were able to find the cause of cough 88 percent of the time. Treatment adjusted for noncompliance was not always a success. While all patients with HA improved, 8 percent of patients without HA or specific diagnosis did not have an improvement in their cough upon retrospective inquiry. Based on this analysis, we find that the diagnosis and treatment of cough may not be as successful as originally reported using Irwin's approach.

Lipid peroxidation (LPO) in the blood plasma and erythrocytes was studied in 99 inhabitants of the southern part of West Siberia suffering from chronic bronchitis, of them 64 with obstructive bronchitis. They were sent for treatment to the contrast climatic zone (Yalta, the Crimea), and LPO was examined before the trip and after return in the course of a month (three times). LPO activity at a later stage as compared to the initial one was raised in the patients with signs of disadaptation (54 patients). The time course of LPO up to the initial level was over up to the 12th day after return in the patients with moderate symptoms of disadaptation in the warm season and up to the 30th day in the cold period. LPO activity in the patients with pronounced symptoms of disadaptation was more noticeable, the time course of the indicators up to the initial level was more delayed, particularly in erythrocytes and in the cold season. Thus LPO activity in chronic bronchitis in terms of its expression and period depends on patients' adaptogenicity to contrast change of climatic geographic zones after therapy in a sanatorium.

The cold-air isocapnic hyperventilation (CAIH) test is a challenge test for non-specific bronchitis which was recently incorporated into the study of bronchial hyperreactivity. As it is easy to perform and to reproduce, the CAIH test is regarded as a valuable examination in clinical pharmacology. We carried out a study using this test in 12 atopic asthmatics in intercritical phase. The patients were treated for a few days before, under double-blind conditions and random order, with Duovent (80 micrograms ipratropium bromide + 200 micrograms fenoterol), fenoterol (400 micrograms), salbutamol (200 micrograms), disodium cromoglycate (DSCG) (10 mg) and placebo. All the drugs were administered by aerosol 30 min before the test which was repeated at intervals of 120, 240 and 360 min after intake of the drug. Certain parameters of respiratory function were measured by dry spirometry (Vicatest 2 C) before administration of the drug as well as before and 0, 3, 5, 15, 30 and 60 min after each test. For the sake of brevity only the FEV1 values are shown in the figures since the other parameters all revealed a similar pattern. After placebo, all the patients reacted to the CAIH test with significant falls after each of the 4 tests, but there was no statistically significant difference between the 4 tests; there were no statistically significant differences between the pretreatment values in FEV1 recorded before each treatment (verum or placebo).(ABSTRACT TRUNCATED AT 250 WORDS)

Weekly data for seven conditions reported to the weekly returns service of the Royal College of General Practitioners' Birmingham research unit over a 52-week period have been compared with those reported to the Oxford regional sentinel practice scheme. The mean weekly recorded rates for otitis media, asthma and intestinal infectious disease were similar in both systems; in the weekly returns service, mean weekly rates for common cold, acute bronchitis and influenza/influenza-like illness were approximately twice and for sore throat/tonsillitis slightly higher than rates in the Oxford scheme.In the weekly returns service no recommendations are made about criteria for diagnosis but in the Oxford scheme diagnostic criteria agreed by the participants are used. Where rates in both monitoring systems are the same, agreed criteria are likely to be conventional clinical practice and therefore superfluous. Where rates are different, the use of criteria enhances specificity of the information content but results in an underestimation of the total incidence of - respiratory disease presented to general practitioners.For common cold, acute bronchitis, otitis media and influenza/ influenza-like illness the associations between the rates in the two systems were high (R>/=O. 79), as might be expected, but these high values cross validate both recording systems in their monitoring of trends. For the remaining (non-epidemic) conditions the associations were low. There were no significant associations between the rates for asthma and the upper respiratory infectious diseases in either recording system, which suggests there was effective discrimination of asthma.

Sixty-three otherwise healthy adults with acute productive cough and no clinical evidence of pneumonia were randomized to receive a ten-day course of erythromycin or placebo. Fifty-seven of these patients returned completed symptom diaries or returned for a two-week follow-up visit. Patients treated with erythromycin reported a more rapid improvement in subjective ratings of cold symptoms, general health, sputum production, and a mean symptom score. Fewer patients in the erythromycin group required cough or cold medications or were congested by day 10 (P less than .05). The treatment group was also less likely to have purulent sputum (9 percent vs 36 percent, P less than .05) and abnormal lung examinations (0 percent vs 29 percent, P less than .01) at a two-week follow-up visit. These results support the use of erythromycin in acute bronchitis.

A cross-sectional epidemiological study was carried out among 141 male subjects exposed to inorganic manganese (Mn) in a Mn oxide and salt producing plant (mean age 34.3 years; duration of exposure, mean 7.1 years, range 1-19 years). The results were compared with those of a matched control group of 104 subjects. The intensity of Mn exposure was moderate as reflected by the airborne Mn levels and the concentrations of Mn in blood (Mn-B) and in urine (Mn-U). A significantly higher prevalence of cough in cold season, dyspnea during exercise, and recent episodes of acute bronchitis was found in the Mn group. Lung ventilatory parameters (forced vital capacity, FVC; forced expiratory volume in one second, FEV1; peak expiratory flow rate, PEFR) were only mildly altered in the Mn group (smokers) and the intensity and the prevalence of these changes were not related to Mn-B, Mn-U, or duration of exposure. There was no synergistic effect between Mn exposure and smoking on the spirometric parameters. Except for a few nonspecific symptoms (fatigue, tinnitus, trembling of fingers, increased irritability), the prevalence of the other subjective complaints did not differ significantly between the control and Mn groups. Psychomotor tests were more sensitive than the standardized neurological examination for the early detection of adverse effects of Mn on the central nervous system (CNS). Significant alterations were found in simple reaction time (visual), audioverbal short-term memory capacity, and hand tremor (eye-hand coordination, hand steadiness). A slight increase in the number of circulating neutrophils and in the values of several serum parameters (ie, calcium, ceruloplasmin, copper, and ferritin) was also found in the Mn group. There were no clear-cut dose-response relationships between Mn-U or duration of Mn exposure and the prevalence of abnormal CNS or biological findings. The prevalences of disturbances in hand tremor and that of increased levels of serum calcium were related to Mn-B. The response to the eye-hand coordination test suggests the existence of a Mn-B threshold at about 1 microgram Mn/100 ml of whole blood. This study demonstrates that a time-weighted average exposure to airborne Mn dust (total dust) of about 1 mg/m3 for less than 20 years may present preclinical signs of intoxication.
