The frequency of asthma in 10 971 school-children between the ages of 5 and 14 years was reported by their parents to be 3-8%. Of these, 20-7% were said to have had bronchitis, 5-9% pneumonia, and 4-7% eczema. Asthma was reported more commonly in boys than girls and was greatest in children of social classes I and II. One-third of the children were reported to have their first attack before the age of 2 years. Few (18%) first attacks started after the age of 5 years. There was no evidence that bronchitis predisposed to the later development of asthma, or vice versa. Within each age-sex group children with a history of asthma had lower peak expiratory flow rates than children who gave no such history. These diffences in PEFR were greater than for children with a history of bronchitis.

This article examines the hypothesis that children with long-term (continuing) asthma attacks are more likely to suffer from allergy-related conditions such as eczema and hayfever than are children who suffer for only a short period of time. The analyses were based on a large British national cohort of children who were studied from birth to 16 years of age. The findings provide evidence in support of the "allergic" model since those with short duration asthma report less eczema, hayfever, and sneezing than do those with long-standing asthma. Short-term asthmatics also report fewer occurrences of bronchitis, pneumonia, and chest infections than those with continuing asthma. These differences suggest that there are underlying etiological differences in children suffering from short- and long-term asthma.

A review of hospital admissions of patients with status asthmaticus at the Childrens Hospital of Los Angeles showed a marked increase in admissions in recent years. Asthma mortality did not increase. Patients tended to be young, boys, and black as compared with patients admitted to a general hospital. Interviews with 100 patients and/or their parents admitted between February and June 1988 indicated that the majority of patients had frequent, severe, and/or disabling symptoms and a significant number were undertreated. Forty-five percent of these patients and 46% of all patients admitted between January 1986 and October 1988 because of status asthmaticus also had sinusitis, otitis, or pneumonitis.

Five-thousand portable or posterior-anterior-lateral radiographs of acute care emergency department patients were interpreted. They revealed serious disease in 35% of patients with chest symptoms, in 27% of all patients examined, and in 18% of patients with noncardiorespiratory symptoms. The highest incidence of abnormal radiographs (42%-79%) occurred in patients with symptoms of congestive heart failure, dyspnea, hemoptysis, dysrhythmia, and hypertension. Asthma (14%) and trauma (5%) presented the lowest incidence of significant findings. Radiographs of patients suspected of having pneumonia were abnormal in 25% of cases, and in those patients with either cough or fever alone, the incidences of pneumonia were 13% and 18%. Whereas 24% of patients with dyspnea alone had radiographic findings of congestive heart failure, 52% of those with congestive heart failure diagnosed on clinical grounds had abnormal radiographs. The chest radiograph continues to be a significantly important examination in the diagnosis of disease, the prevention of overtreatment, and the redirection of clinical investigation in the acute care emergency department unit.

To determine whether hospital admissions for acute childhood asthma were rising in Cape Town in line with the experience of other countries, Red Cross War Memorial Children's Hospital's records for the period 1978-1990 were analysed. These were compared with total admissions for non-surgical causes and lower respiratory tract illness as well as those for bronchiolitis and pneumonia. Asthma admissions showed a sharp upward trend from 1978 to 1984, a slower rise through 1987 and a levelling off since. The profile of hospital admissions for respiratory illness was also analysed. Black children were under-represented among asthma admissions compared with those for pneumonia. Asthma admissions occurred throughout the year but showed seasonal peaks in May and November. Reasons for these trends and patterns are discussed, as well as hypotheses for further research into the epidemiology of asthma in South Africa.

Computed tomography (CT) is useful in evaluating bronchial and bronchiolar abnormalities. Common bronchial and bronchiolar abnormalities include bronchiectasis, asthma, bronchial obstruction, and various forms of bronchiolitis. Causes of bronchiectasis include cystic fibrosis, childhood viral infection, allergic bronchopulmonary aspergillosis, and pulmonary fibrosis. On CT scans, cystic fibrosis may manifest with bronchial wall thickening, bronchiectasis (usually cylindrical, with varicose and cystic forms seen in advanced cases), and mucus plugs in the bronchi. Allergic bronchopulmonary aspergillosis is characterized by central, varicose or cystic bronchiectasis, predominantly in the upper lobes, with mucoid impaction in the bronchi. Traction bronchiectasis may be seen on CT scans of pulmonary fibrosis. Asthma is characterized by bronchial wall thickening due to inflammation. Bronchial dilatation and air trapping may also be seen. Bronchiolitis obliterans is manifested by direct and indirect signs on CT scans; the former consist of centrilobular branching structures and nodules, and the latter consist of bronchiectasis and bronchiolectasis, mosaic perfusion, and air trapping. CT findings of bronchiolitis obliterans organizing pneumonia (also known as cryptogenic organizing pneumonia) include air-space consolidation and nodules, with occasional bronchial dilatation and pleural effusions.

Several studies in recent years have suggested that exposure to airborne particles and to ozone are associated with increases in respiratory hospital admissions. Few of those studies have used inhalable particles as their measure of exposure, and the studies did not always examine both particle and ozone exposure. This study examined the association between both PM10 and ozone and respiratory hospital admissions for persons 65 yr of age and older in the Detroit, Michigan, metropolitan area during the years 1986 to 1989. After controlling for seasonal and other long-term temporal trends, temperature, and dew point temperature, both PM10 (RR = 1.012, 95% CI = 1.019-1.004) and 24-h ozone concentrations (RR = 1.026, 95% CI = 1.040-1.013) were associated with daily admissions for pneumonia. The relative risks are for a 10-microgram/m3 increase in PM10 and a 5-ppb increase in 24-h ozone concentration and from models including both pollutants. Admissions for COPD other than asthma were associated with PM10 (RR = 1.020, 95% CI = 1.032-1.009) and ozone (RR = 1.028, 95% CI = 1.049-1.007) as well. Asthma admissions were not associated with either pollutant. Controlling for one pollutant did not effect the magnitude of the association with the other pollutant. The magnitude of these relative risks are very similar to those recently reported in Birmingham, Alabama, Ontario, and New York State. This suggests that the associations with both pollutants are likely to be causal.

Asthma admissions of children aged 5 years or younger to the Kaiser Foundation Hospital in Honolulu were analyzed for the years 1986-1989. Admissions increased at an annual rate of 4.5% during the study period, in agreement with a worldwide trend. Most children wheezed before their first admission, but their diagnosis was bronchitis rather than asthma. This shows that physicians find it difficult to diagnose asthma in young children. Pneumonia was the initial diagnosis in 25% of admissions, mainly due to overinterpretation of chest radiographs, and this contributed to the overuse of antibiotics. Inpatient treatment with inhaled and systemic bronchodilators and anti-inflammatory agents conformed to standard practice. Recent adoption of the guidelines by the National Asthma Education program and the establishment of an outreach program and asthma register should promote more appropriate outpatient treatment and a reduction of admissions for asthma.

Plastic bronchitis is a rare disorder characterized by the formation and, sometimes dramatic expectoration of long, branching bronchial casts. DIsorders associated with bronchial casts either produce an increase in the volume or viscosity of secretions, such as allergic bronchopulmonary aspergillosis, asthma, cystic fibrosis, pneumonia, and chronic bronchitis; or there are obstructions or structural abnormalities that decrease mucous clearance, such as bronchiectasis. The diagnostic evaluation should include serum laboratory studies, specimen cultures, skin tests, chest radiograph and CT scan, pulmonary function tests, and bronchoscopy. Therapy should be directed towards the underlying disorder and should also include maneuvers to facilitate removal of casts to prevent complications, such as secondary pneumonia.

Asthma is a common and debilitating problem in children. Its many costs to society include morbidity, hospitalization and treatment expenses, and a rising mortality rate. This paper examines recent trends in therapy for status asthmaticus. Oxygen, inhaled beta-adrenergic agonists, and corticosteroids remain the cornerstones of therapy for the child with a severe exacerbation of asthma. Ipratropium bromide provides additional bronchodilatation in the patient who does not respond to standard therapy. Theophylline may have a role in chronic outpatient management of asthma, but the data supporting the addition of this medication in acute therapy for status asthmaticus are inconclusive. Antibiotics are only indicated in children with asthma complicated by infection, such as sinusitis or pneumonia. Magnesium sulfate and heliox may have a role in helping the asthmatic child who is critically ill and for whom other interventions have failed. Mechanical ventilation has many complications. The concept of permissive hypercapnia may be important in limiting barotrauma. Prevention of exacerbations of asthma include limiting environmental exposure to allergens and tobacco, using corticosteroids, and reinforcing compliance with therapy.
