All 607 men, aged 17 to 69, comprising a stratified sample of workers from one shipyard completed a respiratory questionnaire, clinical examination, and detailed spirometry. Chest radiographs were available on 332 men. Among the men aged 50-69 the prevalence of persistent cough and phlegm (chronic bronchitis) was 40%, of wheeze on most days 25%, and undue breathlessness on exertion 25%. After allowing for age the relative risk of welders and caulker/burners having these symptoms were respectively 2.8, 2.2, and 3.1 compared with other shipyard tradesmen. The effects were of comparable magnitude to and interacted with those of current smoking. Among the welders and caulker/burners who smoked, the relative risk of developing chronic bronchitis or undue breathlessness was related to the average fume exposure; the relative risk of wheeze was related to the average fume exposure in all smoking categories, with the strongest association in the ex-smokers. The occurrence of wheeze was also associated with a history of previous metal fume fever. A history of pleurisy but not of pneumonia was related to the fume exposure in the welders. After allowing for age and stature, forced expiratory volume (FEV1) was on average higher in young welders (age less than 30) than other tradesmen. In welders and caulker/burners who were current or ex-smokers, FEV1 and PEF were reduced in relation to the average fume exposure (mean reductions respectively 0.25 l and 0.99 l s-1). The FEV1% (of forced vital capacity), the flow rates at small lung volumes (MEF50%FVC and MEF25%FVC), the mean transit time, and its standard deviation were also reduced by fume exposure or the declines with age were increased, or both. No impairment was demonstrable in the non-smokers and many men had given up smoking with apparently beneficial results. The occupational component of the respiratory impairment related mainly to exposures in the past; information was needed on the effects of present conditions in the industry.

Broncholithiasis, a disease that is probably much more common than has been reported, is most often associated with pulmonary infections, for example, tuberculosis and histoplasmosis. Stones originate from calcified peribronchial lymph nodes that erode into the tracheobronchial tree, but lithoptysis occurs infrequently. The most common symptoms are persistent cough and hemoptysis, sometimes followed by findings of obstructive pneumonia (fever, chills, and purulent sputum). Physical findings are nonspecific, and radiologic findings are varied. Complications include formation of a fistula between the respiratory tract and the esophagus or aorta and obstructive pulmonary symptoms. Treatment ranges from conservative management (simple observation) to thoracotomy for patients in whom complications from stone erosion develop. The prognosis of patients with broncholithiasis is generally excellent.

Congenital tracheobiliary fistulas are uncommon and almost always are diagnosed in the first weeks or months of life. Untreated congenital tracheobiliary fistulas cause intractable pneumonia and are revealed by a persistent cough. Medical therapy is not effective, and surgical repair is needed. A 22-year-old woman was treated successfully by resection of a fistula communicating between the tracheobronchial tree and the liver.

Forty eight patients with the acquired immunedeficiency syndrome (AIDS) presented to the Mount Sinai Hospital in New York with persistent cough and dyspnoea or an abnormal chest radiograph, or both. Thirty two (67%) were found to have Pneumocystis carinii pneumonia, either alone or in combination with another pathogen. Of these patients, eight (25%) had a normal chest radiograph. Abnormalities in the single breath carbon monoxide diffusing capacity and alveolar-arterial oxygen gradient [A-a) DO2) suggested infection with Pneumocystis carinii. Fibreoptic bronchoscopy with transbronchial biopsy was 100% sensitive in the diagnosis of pneumocytis pneumonia. Fibreoptic bronchoscopy should be undertaken in patients suspected of having a pulmonary complication of AIDS, even if the chest radiograph is normal.

Between 1968 and 1983, 54 patients underwent surgery for symptomatic aortic arch and pulmonary artery anomalies at St Christopher's Hospital for Children. Presenting symptoms included stridor, wheeze, apnea, recurrent pulmonary infections, or dysphagia. Diagnosis was established with chest roentgenogram, bronchoscopy, barium esophagram, and arteriography. Four types of vascular anomalies were encountered; double aortic arch (24 patients), right aortic arch with left ligamentum arteriosum (17 patients), anomalous innominate artery (10 patients), and pulmonary artery sling (three patients). There were no intraoperative deaths and only one postoperative death. All surviving patients had immediate relief of their severe respiratory or swallowing symptoms. Mild respiratory symptoms persisted postoperatively from 3 months to 4 years and included frequent or severe upper respiratory infections, persistent cough, stridor and pneumonia. Five of the 53 surviving patients were lost to follow up. The remaining 48 patients were followed from 6 months to 14 years and all but one patient noted complete resolution of all respiratory symptoms. Twenty-nine patients at follow up were old enough to undergo pulmonary function testing including vital capacity, functional residual capacity, and inspiratory and expiratory flow volume loops. Seventeen of these 29 asymptomatic patients consented to these studies, and nine of these patients had abnormal flow volume loops indicative of significant central airway obstruction; the other eight studies were normal. We conclude that surgical repair for vascular rings and slings is safe and symptomatically efficacious. However, anatomic tracheal or bronchial distortion persists in a significant number of these patients as evaluated by pulmonary function studies.

Eight chimpanzees were examined. Two served as negative control and six inoculated with Mycoplasma pneumoniae became colonized. Colonization persisted for 28-68, 16-50 and 21 days with an average duration of 47, 32.5 and 21 days in the oropharyngeal, tracheal and lung tissues, respectively. Mycoplasma titers ranged from 10(8) to 10(1) color-changing units per specimen during the course of the infections. Seroconversion occurred within 12-15 days and peak antibody titers ranged from 1.256 to 1.1024 and developed between days 28 and 48 post-inoculation. Positive cold agglutinin titers were detected between 12 to 15 days and peak titers ranged from 1:80 to 1:640. Significant increases in sIgA and IgG immunoglobulin antibody levels were detected in lung lavage fluids. Unlike the many other experimentally infected animals examined, chimpanzees infected with M. pneumoniae had positive X-ray findings, developed cold agglutinins and showed overt signs of disease. These signs include persistent cough, low grade fever, rhinitis, oropharyngitis, diarrhea, and loss of appetite. Peak severity of disease corresponded with peak lung colonization, and the detection of cold agglutinins and positive X-ray findings. The microbiological, serological and clinical aspects of pneumonia induced in chimpanzees was similar to naturally occurring primary atypical pneumonia in humans.

A 70-year-old woman with no history of smoking was admitted to the hospital because of a persistent cough and pneumonia in the right lower lobe. Examination with a fiberoptic bronchoscope revealed an intratracheal polypoid tumor and a polypoid tumor almost completely obstructing the right bronchus B(8). Biopsies were done, and histological diagnosis of both tumors was squamous cell carcinoma. A sleeve resection of the trachea with end-to-end anastomosis and right lower lobectomy were done. Examination of specimens resected from both tumors revealed moderately differentiated squamous cell carcinoma. Synchronous double-primary cancer (both squamous cell carcinoma) of the lung and trachea in a non-smoker is very rare.

The objective has been to identify the different etiologies and elaborate a diagnostic and therapeutical methodology for patients with chronic cough. During one year we studied prospectively 83 patients with persistent cough of daily appearance with an evolution of four or more weeks and no previous etiologic diagnosis. We worked on three diagnostic (D) levels. D1: Based on the anamnesis and physical examination. D2: Sequential incorporation of complementary exams. D3: Evaluation of the response to the specific treatment. We divided the population into 2 groups: G1 healthy children, G2 children followed in our hospital for different conditions. The mean age was 4.7 years (range, 3 months to 15 years), and the average duration of cough was 4.9 months (range, 1 to 36 months). In G1 the following causes were identified in 78 children: cough variant asthma 41 (52%), asthma+upper respiratory tract infections 8 (10%), asthma+lower respiratory tract infections 6 (7%), postnasal drip syndrome (sinusitis, adenoiditis) 5 (6%), psychogenic 6 (7%), undetermined 4 (5%), gastroesophageal reflux 2, asthma+cigarette 2, AIDS 1, Sjogren syndrome 1, vascular ring 1, cricopharyngeal foreign body 1. In G2 out of 5 children we have found: 2 children with chronic encephalopathies who had swallowing disorders and gastroesophageal reflux, 1 patient with Down syndrome presenting hypogammaglobulinemia and bronchiectasis, 1 tracheaesophageal fistula in H in a child with recurrent pneumonia, 1 lymphocytic pneumonia in an AIDS patient. The D1 was correct in 92% of the cases. The specific therapy has proved useful for achieving the remission of the symptoms. Although asthma is the most frequent cause of chronic cough, other etiologies exist and must be ruled out.

This study analyzes patient demand in a regional public health pulmonology practice. The following data were recorded for all first-visit patients for a period of two years: age, sex, referral source, initial diagnosis by the referring physician, final diagnosis by the pulmonologist, and destination. The service studied 1,486 patients (men/women: 1.5). Most (71%) were between 40 and 80 years old. Referrals were from the family doctor (60%), health center (9%), emergency service (10%), hospital (12%), other specialists (6%), and others (3%). The most frequent reasons for remission were upper airway disease (UAD) (36%), specifically chronic obstructive pulmonary disease (COPD) and asthma, and the presentation of symptoms (28%) such as dyspnea, cough, hemoptysis and chest pain. Analysis of the final diagnoses for the patients presenting with symptoms showed that no disease could be detected in one third of those with dyspnea and hemoptysis or in half of those who complained of chest pain; acute respiratory infection was diagnosed in 45% of those complaining of persistent cough. UAD was the most frequent cause of symptoms. The index of doctor's visit/inhabitant was 0.97% for patients referred by family doctors and 0.38% for those from health centers, but the initial and final diagnosis profiles of these patients were not statistically different. Patients referred by emergency services had significantly more (p < 0.001) in number of radiological findings and hemoptysis. Those sent from hospitals more often suffered pneumonia. In conclusion, this profile of a regional public health pulmonology practice shows that: 1) UAD and clinical symptoms are the most frequent reasons for patient remission; 2) family doctors generate three times mor demand for services than do health centers, and 3) 14% of patients can be considered normal.
