Association of snoring with chronic bronchitis.

Background: Snoring is more prevalent in patients with chronic bronchitis than in persons without it. Few studies have examined the effect of snoring on chronic bronchitis. We prospectively investigated the association between snoring and the incidence of chronic bronchitis.

Aspiration pneumonia due to polyethylene glycol-electrolyte solution (Golytely) treated by bronchoalveolar lavage.

Polyethylene glycol (PEG)-electrolyte solution (Golytely), is most commonly used for bowel preparation before colonoscopy, as well as for barium enema and colon surgery. In this case, a 70-year-old man developed ARDS following the administration of Golytely by mouth before a scheduled colonoscopy. Aspiration of PEG-electrolyte solution was suspected, and the patient was successfully treated by BAL.

Clinical characteristics of acute pulmonary thromboembolism in Korea.

Background: Acute pulmonary thromboembolism (APTE) remains an important cause of morbidity and mortality in Western countries. In Korea, both the incidence and the mortality rate of APTE were thought to be low compared to Western countries. We performed the present study to investigate the current status of APTE in Korea.

Association of habitual snoring with glucose and insulin metabolism in nonobese Korean adult men.

Habitual snoring is associated with cardiovascular morbidity and mortality, and metabolic abnormalities such as impaired glucose homeostasis. Many studies were performed in obese Western populations. The purpose of this study was to examine the association of habitual snoring with glucose and insulin metabolism in nonobese Korean men who were free of diabetes and hypertension.

Relation of epidermal growth factor receptor expression to mucus hypersecretion in diffuse panbronchiolitis.

Study Object: Diffuse panbronchiolitis (DPB) is a hypersecretory airway disease, and the mechanism of mucus hypersecretion in DPB is poorly understood. Moreover, mucin synthesis in the airways has been reported to be regulated by neutrophilic inflammation-induced epidermal growth factor receptor (EGFR) expression, and the degranulation of goblet cells is known to be mediated by neutrophilic elastase. In this study, we examined the relationship between EGFR expression in the bronchiolar epithelium with neutrophilic inflammation and mucus hypersecretion in the tissues of DPB patients.
