Eight collie-cross pups, eight weeks old, were inoculated intramuscularly with an aluminum hydroxide adjuvanted preparation of killed Bordetella bronchiseptica; the inoculation was repeated after two weeks. Two weeks after the second inoculation, the vaccinated dogs and a control group of four unvaccinated animals were placed in contact with a group of five pups of similar age which had been experimentally infected with a pathogenic strain of B bronchiseptica by an aerosol method. All four unvaccinated control dogs as well as all five experimentally infected dogs developed a respiratory disease characterised by persistent coughing. Six of the vaccinated dogs remained free from clinical respiratory disease while disease was less severe and of shorter duration in the remaining two than in controls. Only slight changes were found in the lungs of vaccinated animals at necropsy while in the controls there was a severe tracheobronchitis. There was a marked reduction in the numbers of B bronchiseptica isolated from the respiratory tract of vaccinated animals when compared with controls. An aluminium hydroxide adjuvanted vaccine may be of value in controlling naturally occurring canine respiratory disease in which B bronchiseptica is involved.

The efficiency of the Racal Airstream helmet respirator in improving peak expiratory flow rates (PEFR) and symptoms (dyspnea, wheezing, and cough) in aluminum potroom workers with respiratory complaints was assessed in 19 workers. Peak expiratory flow readings and symptom recording from a 2-week working period with use of the respirator were compared with a period when the 3M 9906 disposable mask was used. The study was designed as a randomized, parallel, cross-over study with five or six daily measurements of PEFR and daily symptom recording. A significant number of workers (15) had a higher mean peak flow in the helmet period than in the nonhelmet period (p less than 0.01); symptoms did not improve significantly in the helmet period. Objective evidence of respiratory protection was observed for the group of workers as a whole, but the effect on symptoms as well as individual effect on peak flow was minor in the majority of the workers.

A 42-year-old woman presented with chronic cough and dyspnea. A leiomyoma of the right middle lobe of the bronchus was diagnosed by bronchoscopic biopsy and treated successfully by neodymium-yttrium aluminum garnet laser, via fiberoptic bronchoscope. The presentations of bronchial leiomyoma are mainly due to partial or complete occlusion of the involved bronchus. Symptoms are mainly cough, wheeze, chest pain and fever, as a result of atelectasis, consolidation, collapse or bronchiectasis. The management of this benign tumor of the lung is discussed, and the importance of early diagnosis and conservative therapy are emphasized.

The new International Union Against Tuberculosis (IUAT) bronchial symptoms questionnaire was completed by 827 subjects participating in a prospective study of respiratory symptoms and lung function in aluminum smelter workers. A modified Medical Research Council (MRC) questionnaire was also administered. Bronchial reactivity (BR) was measured in 809 subjects by methacholine challenge using a rapid method. Factor analysis demonstrated sensible clustering of responses to items unique to the new questionnaire such as nocturnal, spontaneous, and postexertional dyspnea, dust-induced dyspnea and tightness, and breathing difficulty. Responses to IUAT questions concerning past asthma, wheeze, chest tightness, morning cough and sputum, and asthma medication agreed well with corresponding items from the MRC questionnaire. Questions concerning asthma, medication, dust-induced, nocturnal, and spontaneous dyspnea, chest tightness, wheeze, nocturnal cough, postexertional dyspnea and breathing difficulty also had high validity against the criterion of concurrently measured bronchial reactivity. It is concluded that the IUAT questionnaire is a valid asthma questionnaire.

Three basic techniques (and one modified technique) were developed, allowing successful excision of subepiglottic cysts in 10 horses (5 Standardbreds, 4 Thoroughbreds, and 1 Quarter Horse; mean age, 3.5 years) via peroral approach. This approach eliminated the need for laryngotomy or pharyngotomy and reduced postoperative care. None of the cysts redeveloped. Clinical signs of disease before surgery included respiratory noise, exercise intolerance, coughing, and dysphagia and were eliminated in all horses except one that raced successfully, but in which some respiratory noise was detected. Peroral subepiglottic cyst excision was performed on anesthetized horses that were positioned in lateral recumbency and intubated via the nares and trachea. General anesthesia allowed careful intraoral palpation and endoscopic visualization of the oropharynx on a television monitor. Custom-designed instruments, including a guide tube, cyst snare, and long grasping forceps, facilitated either laser or snare, or laser and snare cyst excision. Hemorrhage was negligible in all horses. Initial attempts to develop a technique to submucosally excise subepiglottic cysts through a transnasal transendoscopic approach in conscious horses, using a contact neodymium:yttrium aluminum garnet laser, were unsuccessful. In each of 3 horses, the cyst was inadvertently penetrated before it could be excised, causing it to collapse and disappear beneath the soft palate. Postoperative complications were excessive subepiglottic swelling after laser excision (n = 1 horse), which resolved completely in response to anti-inflammatory treatment, and subepiglottic cicatrix formation after snare excision (n = 1 horse), which required surgical excision of the cicatrix.

Transendoscopic neodymium:yttrium-aluminum-garnet (Nd:YAG) laser was used to treat 12 standing horses with epiglottic entrapment (EE) or dorsal displacement of the soft palate (DDSP), or both. In four horses, transendoscopic laser staphylectomy was performed. The most common presenting complaints were respiratory stridor, cough, and exercise intolerance. Ten horses with EE healed without epiglottic complications; in one horse, partial adhesion of the aryepiglottic fold to one side of the epiglottis was corrected surgically through a laryngotomy incision. One horse with DDSP had no further signs, one continued to have continual DDSP, and two had induced DDSP. Transendoscopic Nd:YAG laser proved to be a feasible means of correcting EE and selected cases of DDSP.

Neodymium-yttrium-aluminum-garnet laser treatments were performed in 70 patients aged 62 +/- 10 (1 SD) years for incomplete malignancy-induced obstruction of the trachea or main bronchi, or both, associated with uncontrolled cough, dyspnea, atelectasis/pneumonia, and hemoptysis. Forty-three patients had been treated with surgical techniques, chemotherapy, or radiotherapy, or all three, while 27 patients were untreated before laser therapy because of acute respiratory distress. Laser treatment produced palliative improvement in 81% of the treated group (35 of 43), with survival of 4.3 +/- 3.9 months. Unsuccessfully laser-treated patients survived 0.7 +/- 0.4 month (p less than .05). Eighty-five percent of the untreated patients (23 of 27) showed postlaser improvement, with survival of 8.5 +/- 6.9 months. Unsuccessfully laser-treated patients survived 1.4 +/- 0.6 months (p less than .05). Twenty-three of the 27 previously untreated patients underwent radiation therapy after laser treatment. Laser treatments also were administered to 23 patients aged 61 +/- 13 years with complete obstruction of the main bronchi. Of this group, 17 patients had been treated and 6 had not been treated before the laser therapy. Laser treatment was successful in 47% of the treated patients (8 of 17), but there was no difference (p greater than .05) in survival between successfully and unsuccessfully treated patients (3.0 +/- 2.5 vs. 2.9 +/- 4.6 months). Similarly, laser treatment was successful in 50% of the untreated patients (3 of 6), and there was also no difference (p greater than .05) in survival between successfully and unsuccessfully treated patients (3.4 +/- 3.5 vs. 3.5 +/- 2.8 months).(ABSTRACT TRUNCATED AT 250 WORDS)

We conducted a 6-y follow-up study that included workers in an aluminum smelter in British Columbia. Of the original cohort, 951 workers left the industry and 985 workers participated in both studies. Comparison of those who left and those who remained showed that those who left were (1) older, (2) had a slightly higher prevalence of respiratory symptoms, and (3) had lower lung function; this was especially true for workers who were 50 + y of age at the time the initial study was conducted. Analyses were conducted only on 586 male workers who did not change their job location or smoking habits between the initial and the follow-up study. Potroom workers in the "high-exposure" group had a significant reduction in the prevalence of cough, but experienced an increase in the prevalence of wheeze. There was no significant difference in the annual decline in forced expiratory volume in 1 sec and forced vital capacity between the potroom workers and controls. In general, older workers and smokers had a greater decline in lung function compared to younger workers and nonsmokers. Leukocyte count done during the initial study was found to be an independent predictor of longitudinal decline in lung function. The lack of exposure effect on longitudinal decline in lung function could be due to "healthy worker" effect and improvement in the working condition of the smelter.

To evaluate the health effects of occupational phosphine exposure, 22 workers engaged in fumigation of stored grains were subjected to a clinical and environmental study. These workers were used to placing aluminum phosphide tablets on the stacks of grains and covering it with a gas-proof plastic cover. The mean age of the workers was 48 years (range 24-60) and mean duration of exposure 11.1 years (range 0.5-29). After fumigation they reported minor symptoms, which included cough (18.2%), dyspnoea (31.8%), tightness around the chest (27.3%), headache (31.8%), giddiness, numbness and lethargy (13.6% each), anorexia and epigastric pain (18.2% each). The abnormal physical signs included bilateral diffuse rhonchi and absent ankle reflex each occurring in one worker. Motor nerve conduction velocity of median and peroneal nerves, and sensory conduction velocity of median and sural nerves were normal. Phosphine concentration in the work environment ranged from 0.17 to 2.11 ppm. Occupational phosphine exposure in the workers was associated with mild to moderate symptoms, which were transient. However, to assess the chronic effects, long-term follow-up is recommended.

Thirty-five men developed bronchial asthma while working in the potrooms in a primary aluminum production plant. Their asthma was diagnosed as work-related ("potroom asthma"). When examined 1-43 months after cessation of exposure (average follow-up period 2.5 yr), the group had an increased relative risk of morning cough (RR 1.7 CL95% 0.6-5.1), dyspnea on exertion (RR 2.8 CL95% 0.9-8.4), and wheezing (RR 6.1 CL95% 2.3-16.3) compared to controls from the same plant, in a 1:2 matched analysis. Matching criteria were age, smoking habits, and time of employment in the plant. The group means for FEV1 and MMEF were lower than for the controls, but the differences were not statistically significant. Ten of the 35 reported persisting asthma, dyspnea at night, or dyspnea on exertion. The study indicates an increased risk of respiratory dysfunction after potroom asthma. Medical follow-up after cessation of exposure is recommended.
