Impact of chronic obstructive pulmonary disease (COPD) in the Asia-Pacific region: the EPIC Asia population-based survey.

Background: Chronic obstructive pulmonary disease (COPD) is a clinical syndrome encompassing a group of chronic, progressive, and debilitating respiratory conditions, that are characterized by incompletely reversible airflow limitation. Within the Asia-Pacific region, prevalence estimates have been derived using various protocols and study methods, and there is little data on the impact of COPD exacerbations. This study aimed to provide a comprehensive picture of the current prevalence and burden of COPD in this region.

Prevalence of gastroesophageal reflux in Thai asthmatic patients.

Background: Asthma is a chronic inflammatory disorder of airways and associated with airway hyperresponsiveness and reversible bronchoconstriction. Gastroesophageal reflux disease (GERD) is a disorder caused by the reflux of gastric content up into the esophagus. It has been proposed that GERD is one of the exacerbating factors in the patients with poor controlled asthma.

Pulmonary alveolar proteinosis: a report of seven patients from King Chulalongkorn Memorial Hospital.

From 1983 to 2001, 7 patients with pulmonary alveolar proteinosis were admitted to the King Chulalongkorn Memorial Hospital. Presenting symptoms varied from asymptomatic (1 patient), progressive dyspnea on exertion (4 patients) to respiratory failure (2 patients). Other symptoms included dry cough and weight loss.

Survey of asthma control in Thailand.

Objective: The aim of the study was to determine whether asthma management in Thailand is succeeding in achieving the levels of control, specified in national and international asthma guidelines.

Methodology: Adults with asthma in Bangkok, Chiang Mai, Songkhla, and Khon Kaen were interviewed, and we have reported on their asthma severity, morbidity, control, perception of asthma, and healthcare use.

Results: A total of 466 asthma sufferers were interviewed.

Bronchiolitis obliterans syndrome after heart-lung transplantation: a case report and review of literature.

Bronchiolitis obliterans syndrome (BOS) is regarded as a manifestation of chronic rejection after lung transplantation and remains the major cause of late morbidity and mortality after lung and heart-lung transplantation. The authors, herein, reported the first documented case of a patient who receiving heart-lung transplantation at our institute and developed BOS as a late complication. The patient presented 5 years after received heart-lung transplantation with progressive shortness of breath due to obstructive lung disease.

Acute effect of sulphur dioxide from a power plant on pulmonary function of children, Thailand.

Background: Epidemiological studies have shown reversible declines of lung function in response to air pollution, but research on the independent effect of short-term exposure to ambient sulphur dioxide (SO2) on pulmonary function is limited. This study evaluated the association of short-term exposure to increased ambient SO2 and daily pulmonary function changes among children with and without asthma.

Methods: The associations of daily exposure to SO2 and particulate matter 10 microm in diameter (PM10) with pulmonary function were examined in 175 asthmatic and non-asthmatic children aged 6-14 years who resided near a coal-fired power plant in Thailand.
