1. Capnografia volumétrica na avaliação de crianças e adolescentes com asma persistente / Volumetric capnography for the avaliation of children and adolescents with persistent asthma
Objective: To study changes in the variables of volumetric capnography in children and adolescents with persistent asthma compared with controls, and investigate their changes with the use of bronchodilators and in response to bronchial provocation test. Methods: Hundred-three asthmatics and 40 healthy volunteers (aged 6-15 years) were serially enrolled. Spi

2. Pulmonary function and screening for allergic asthma in patients with common variable immunodeficiency / Avaliação da função pulmonar e investigação da asma alérgica em pacientes com imunodeficiência comum variável
A imunodeficiência comum variável (ICV) é uma síndrome heterogênea caracterizada por hipogamaglobulinemia e infecções bacterianas de repetição. As doenças obstrutivas, como a asma, estão presentes em aproximadamente 50% dos pacientes. Os sintomas decorrentes de infecções respiratórias de repetição podem mascarar os sintomas de alergia respira

3. Quantitative skin prick and bronchial provocation tests with platinum salt.
Occupational asthma due to platinum salts is a frequent disease in platinum refineries. The diagnosis is based upon a history of work related symptoms and a positive skin prick test with platinum salts. Bronchial provocation tests have not been performed in epidemiological studies because the skin test is believed to be highly specific and sensitive. As no r

4. Interstitial lung disease and asthma in hard-metal workers: bronchoalveolar lavage, ultrastructural, and analytical findings and results of bronchial provocation tests.
Five patients with respiratory disorders associated with hard metal exposure are described. In four patients electron microprobe analysis of bronchoalveolar lavage cells or lung tissue was used to show tungsten and other hard-metal components. Three patients had interstitial pneumonia and fibrosis with unusual multinucleate giant cells. Electron microscopy s

5. Occupational asthma in a hairdressing salon.
Occupational asthma among hairdressers has been recognised for some years and cases of work related asthma due to hair bleaches containing persulphates and hair dyes have been reported. The extent of the disease among hairdressers remains unknown. An investigation was carried out on an entire hairdressing salon, which specialised in hair bleaching and colour

6. Occupational asthma in a coal miner.
Occupational asthma in coal miners is hardly recognised. A report is presented of a coal miner whose clinical picture suggested a respiratory allergy which occurred only in the mine where he worked. Serum specific IgE levels, skin tests, and bronchial provocation tests with different commercial extracts showed sensitisation to Rhizopus nigricans. Rhizopus sp

7. Effect of antihistamines and antiallergic drugs on responses to allergen and histamine provocation tests in asthma.
The inhibition of immediate allergen or histamine induced airflow obstruction by inhaled ketotifen, clemastine, sodium cromoglycate, and placebo was studied in two groups of asthmatic subjects. Single doses of ketotifen (0.5 mg), clemastine (0.5 mg), sodium cromoglycate (20 mg), or placebo were administered by inhalation 45 minutes before bronchial provocati

8. Sauna builder's asthma caused by obeche (Triplochiton scleroxylon) dust.
Two carpenters developed rhinitis, conjunctivitis, bronchial wheezing, and dyspnoea while using obeche (Triplochiton scleroxylon, African maple) at their work while they built saunas. Skin prick tests showed an immediate reaction, specific IgE to obeche was detected in their serum, and bronchial provocation test with obeche gave an immediate reaction with de

9. Occupational asthma due to glutaraldehyde and formaldehyde in endoscopy and x ray departments.
BACKGROUND--Glutaraldehyde is the best disinfectant for fibreoptic endoscopes. It is also used in the processing of x ray films. A number of studies have reported eye, nose, and respiratory symptoms in exposed workers. Three individual case reports of occupational asthma in endoscopy workers and a radiographer have also been published. We describe a further

10. Occupational asthma due to soft corrosive soldering fluxes containing zinc chloride and ammonium chloride.
Two cases of occupational asthma due to soft corrosive soldering fluxes used in metal jointing are described in which the diagnosis was based on work related deterioration in daily peak expiratory flow rate and positive responses in bronchial provocation tests. Both fluxes contained ammonium chloride and zinc chloride. Occupational asthma provoked by these a

11. Occupational asthma due to an emulsified oil mist.
A toolsetter developed occupational asthma due to the oil mist generated by his lathe on which it was used as a coolant. The diagnosis was confirmed by serial measurements of peak expiratory flow at home and work, including a prolonged period away from work. Occupational type bronchial provocation tests were performed using the whole emulsified oil and its c

12. Effect of pH on bronchial response to inhaled histamine.
In order to investigate the effect of pH on bronchial responsiveness to inhaled histamine, 15 subjects with non-specific bronchial hyperreactivity performed two histamine inhalation tests, one with unbuffered, and the other with buffered histamine acid phosphate solutions. The unbuffered histamine solutions were prepared with 0.9% sterile saline and had a pH
