The aim of this part of the FinEsS-studies was to assess whether differences existed in prevalence of asthma, chronic bronchitis, and respiratory symptoms between three Baltic capitals, and to examine risk factor profiles for respiratory conditions. In 1996, a postal survey was performed in these cities with a response rate of 72% in Stockholm, 76% in Helsinki, and 68% in Tallinn. The prevalence of physician-diagnosed asthma was 76% in Stockholm, 6.2% in Helsinki, and 2.3% in Tallinn, while respiratory symptoms were most common in Tallinn. The prevalence of physician-diagnosed chronic bronchitis was 10.6% in Tallinn, 3.4% in Helsinki, and 3.0% in Stockholm. Risk factor analyses revealed a significantly increased risk for those living in Tallinn compared to that of Stockholm for wheezing conditions, OR 1.56-1.69, longstanding cough, OR 1.92 (1.74-2.13), attacks of shortness of breath during the previous 12 months, OR 1.35 (1.20-1.52), and chronic productive cough, OR 1.49 (1.28-1.74). Subjects having symptoms common in asthma were more likely to have physician-diagnosed asthma in Stockholm and Helsinki than in Tallinn, while subjects having bronchitis symptoms had more often physician-diagnosed chronic bronchitis in Tallinn. Prevalence of respiratory symptoms was higher in Tallinn than in Stockholm and Helsinki, while physician-diagnosed asthma was more common in Stockholm and Helsinki. The prevalence of physician-diagnosed chronic bronchitis was three times as high in Tallinn as in Helsinki or Stockholm. Our results also suggest large differences in diagnostic practices between the three countries, while the differences between the capitals in true prevalence of disease may be small.

A cross-sectional descriptive study to determine the economic burden in management of acute lower respiratory infection from the patient's perspective was conducted at Takhli District Hospital from March 2000 to February 2001. Information obtained from interviewing caretakers of 165 children with LRI and data collected from medical records revealed the cost per case ranged from 140 to 6,471 baht with an average total cost per case of 1248 baht. The main determinants of the average total cost per case included the diagnosis of diseases, type of patient (outpatient or inpatient), wheezing association and respiratory syncytial virus positivity. Children with severe pneumonia accounted for the highest in the average total cost per case (2,348 baht) while those with bronchitis accounted for the lowest (924 baht). The average total cost per case of inpatients was 3.5 times higher than that of outpatients. Health policy efforts to improve the effectiveness of care in an ambulatory setting may reduce the financial cost of the illness.

Wheezing was detected in 251 of the 421 (59.6%) children under 5 years old suffering from acute lower respiratory infections (LRI) treated at the Takhli Hospital, Nakhon Sawan Province from November 1998 to October 2000. Bronchitis and pneumonia accounted for 55.0 per cent and 40.6 per cent of LRI with wheezing. Most of the patients, 162 of 251 (64.5%) cases were children under 2 years old. The wheezing symptom declined significantly in children older than 4 years of age. In this study, LRI with wheezing was found all year round but was more frequent in the rainy season similar to other respiratory infections. As the respiratory syncytial virus (RSV) infections were mainly found during the rainy season (July-October), the association of wheezing and RSV infections in the rainy season was evaluated. RSV causing LRI with wheezing in the rainy season revealed 54.7 per cent and 39.4 per cent in the first and second studied year, respectively. The two-year follow-up of 121 cases of LRI with wheezing showed that 37 cases (30.5%) had repeated episodes of wheezing. In conclusion, LRI with wheezing caused by RSV was commonly found in children under 2 years old. The occurrence was all the year round but predominantly in the rainy season.

Exposure to particulate matter (PM) may exacerbate preexisting respiratory diseases such as asthma, chronic obstructive pulmonary disease (COPD), bronchitis, and pneumonia. However, few experimental studies have addressed the effects of PM on lower respiratory tract (LRT) viral infection. Respiratory syncytial virus (RSV) is a major etiological agent for LRT infections in infants, the elderly, and the immunocompromised and may lead to chronic wheezing and the development of asthma in children. In this study, we examined the effects of carbon black (CB) on RSV-induced pulmonary inflammation, chemokine and cytokine expression, and airway hyperresponsiveness in a mouse model of RSV. Female BALB/c mice were instilled via the trachea (i.t.) with 1 x 106 plaque forming units (pfu) RSV or with uninfected culture media. On day 3 of infection, mice were i.t. instilled with either 40 micro g ultrafine CB particles or with saline. End points were examined on days 4, 5, 7, and 14 of RSV infection. Viral titer and clearance in the lung were unaffected by CB exposure. Neutrophil numbers were elevated on days 4 and 7, and lymphocyte numbers were higher on days 4 and 14 of infection in CB-exposed, RSV-infected mice. CB exposure also enhanced RSV-induced airway hyperresponsiveness to methacholine, bronchoalveolar lavage (BAL) total protein, and virus-associated chemokines monocyte chemoattractant protein (MCP-1), macrophage inflammatory protein (MIP-1 alpha), and regulated upon activation, normal T cell expressed and secreted (RANTES). MIP-1 alpha mRNA expression was increased in the alveolar epithelium, where ultrafine particles deposit in the lung. These data demonstrate a synergistic effect of ultrafine CB particles on RSV infection, and suggest a potential mechanism for increased respiratory infections in human populations after PM exposure.

The recent understanding of the key role of adhesion molecules in the pathogenesis of chest allergy in parasitic infections may provide a pharmacological target for the associated asthmatic symptoms. Circulating levels of the endothelial cell adhesion molecules (CAMs): sICAM-1, sVCAM-1 and sE-selectin in sera of 18 allergic asthmatic patients. 16 fascioliasis cases (acute & chronic), 24 fascioliasis cases with allergic chest manifestations and 10 apparently healthy control subjects were estimated by ELISA method. Also, IL-4 serum level was evaluated in all groups. Chest allergy in association with fascioliasis included mainly bronchial asthma, beside eosinophilic bronchitis, persistent wheezing and chronic cough. The study provided evidence that adhesion molecules expression is up regulated in acute and chronic fascioliasis cases with allergic chest manifestations. sVCAM-1 seemed to be an early indicator of asthma development in human fascioliasis. IL-4 cytokine was suggested to be responsible for the increased expression especially in the chronic phase of the disease, yet the role of other cytokines cannot be excluded.

There is convincing evidence that several distinct wheezing syndromes exist in childhood. The purpose of this research was to assess the potential of using healthcare utilization profiles to identify wheezing syndromes in children which are distinct from asthma. Using population-based healthcare administrative data, a cohort of children, aged 5-15 years, with bronchitis diagnoses from time of birth to 1995, but no physician diagnoses of asthma, was followed over the period January 1996-March 1998. In this follow-up period, 13% had subsequent healthcare utilization for asthma, 23% had continued healthcare utilization for bronchitis, and 64% had no further healthcare utilization. The likelihood of bronchitis vs. asthma outcomes was determined for a variety of asthma risk factors. In a cohort of 11,043 children with initial healthcare contact for bronchitis but not asthma, two potentially distinct entities of bronchitis emerged from our data: 1) transient bronchitis, similar to transient wheezing of early childhood, which was associated with winter-only healthcare utilization and absence of allergy, and 2) recurrent bronchitis which differed from asthma on the basis of winter-only healthcare utilization, prematurity at birth, absence of allergy, and low socioeconomic status. Healthcare administrative records can be used to describe the natural history of wheezing in children and to identify markers which may discriminate asthma from other syndromes.

Chronic and recurrent respiratory tract disorders are a frequent problem in general practice. The purpose of the study was to investigate the role of hypersensitivity to house dust mites in respiratory tract diseases in general practice patients. We tried to assess the influence of determined risk factors exposure on development of respiratory tract allergy. Patients from family practitioners surgeries with chronic or recurrent respiratory tract symptoms who had no diagnosis of allergy were recruited to the study (n = 89). All patients responded to a questionnaire focused on history of symptoms, atopic conditions in family and exposure to determined environmental factors like dwelling conditions, obstetrician history, diet in the first year of life. All patients underwent skin prick test with common inhalant allergens. Families of the patients were asked to participate in the study. Families who agreed to take part also responded to the questionnaire and underwent skin tests. In patients and their families blood samples were taken to determine total IgE and specific IgE antibodies to mites allergens. Dust samples were collected by vacuuming of patients' bedroom carpets and mattresses to determine house dust mites allergens concentration. Data on 30 complete patients family sets of their brotherhood, mother and father were collected. Total and specific serum IgE antibodies were determined by disc enzyme-immunoassay (Analco). Mites allergens concentration in dust was measured by simple Acarex strip test (Nexter). The results of the assays (positive skin tests and/or elevated levels of specific IgE) showed allergy to house dust mites in 24 of 89 study patients from general practitioners surgeries (27%). The prevalence of chronic rhinitis, recurrent bronchitis, chronic or recurrent cough, wheezing, dyspnoea was higher in allergic than in nonallergic subjects. Patients with the diagnosis of allergy to house dust mites had usually worse dwelling conditions. Especially the influence of dampness in flats on several respiratory symptoms was observed. Subjects who had been found to be allergic were more frequently exposed to higher concentrations of house dust mites allergens in bedroom carpets and in mattresses. In allergic children early introducing of sensitizing components into the diet in infancy related to shorter breast feeding was observed.

Foregut cysts frequently cause symptoms in the first three decades of life. The symptoms consist of dyspnea, wheezing, cough and sputum, dysphagia, stridor, and those associated with right heart strain. Symptoms and the radiological appearance of the uncomplicated cyst mimic mediastinal tumour and mediastinal obstruction. The symptoms and radiological appearance of the ruptured infected cyst simulate those of lung abscess, diaphragmatic hernia, ruptured hydatid cyst, cavitated peripheral carcinoma and pulmonary tuberculosis. In this series the differentiation from other cysts was made thus: with intralobar sequestration, a systemic arterial blood supply was demonstrated; with hydatid cyst, there was a positive intradermal skin test and (radiologically) following rupture, the appearance of a pericystic pneumatocele followed by the water-lily sign was diagnostic; with emphysematous cysts, the signs of associated bronchitis were present; in the presence of pseudocysts, there was a previous history of lung abscess, staphylococcal infection or tuberculosis. Cysts should be removed when first diagnosed.

A 29-year-old man was admitted to our hospital complaining of cough, wheezing, dyspnea, and fever one month after handling paint spray containing isocyanate (MDI). Chest HRCT findings showed diffuse ground-glass attenuation in both lung fields. A pulmonary function test revealed restrictive impairment, and the reversibility test was positive. His symptoms, HRCT findings, and pulmonary dysfunction were improved only after the cessation of isocyanate administration. BALF showed lymphocytosis, and the pathological findings of the TBLB specimen revealed cellular alveolitis, but no Masson bodies or epitheloid cell granuloma. As a result of environmental provocation, fever, hypoxia, and reduced peak expiratory flow developed, and the environmental provocation test was positive. The specific antibodies against MDI and TDI were positive in both serum and BALF, and the lymphocyte stimulation test against MDI was positive in peripheral blood. Combined hypersensitivity pneumonitis and bronchial asthma due to isocyanate were therefore diagnosed. Pulmonary dysfunctions due to isocyanate are known to include bronchitis, bronchial asthma, and hypersensitivity pneumonitis. However, case reports of combined hypersensitivity pneumonitis and bronchial asthma due to isocyanate are rare.

OBJECTIVE: To assess the prevalence of asthma symptoms and of asthma in children due to the high frequency of pediatrics patients with symptoms suggestive of the disease and to the lack of data regarding prevalence of asthma in this population. METHODS: We carried out a cross-sectional study with 2,735 school-age children aged 6-7 years and 3,509 adolescents aged 13-14 years selected by random sampling. Data were collected between 1998 and 1999 using a translated version of the questionnaire of the International Study of Asthma and Allergies in Children, which has been previously tested and approved. Guardians were responsible for answering the questionnaire of younger children, whereas adolescents answered their own, in classroom. The data were computed and analyzed using EPI-info software. RESULTS: The response rates for questionnaires were 73.2% (6-7-years old) and 94% (13-14 years old). The prevalence of symptoms in children and adolescents were, respectively: wheezing ever 46.7% and 44.3% (P<0.05); wheezing in the last 12 months 22.7% and 21.2%; speech limited due to wheezing 4.7% and 4.0%; wheezing following exercise 6.3% and 18.2% (P<0.05); nighttime cough in the last 12 months 38.5% and 45.8% (P<0.05); asthma (bronchitis) ever 28.2% and 26.4% (P=0.11). CONCLUSIONS: The prevalence of asthma symptoms and of asthma of the two groups are among the highest results ever reported in Brazil; these results were compatible with those of high prevalence results reported worldwide using ISAAC questionnaires. The high prevalence of symptoms suggests a high prevalence of the disease, which makes asthma an important problem for public health in the region.
