OBJECTIVES: For years, South Korea has had one of the highest levels of tobacco use among males in the world, but a steady decline has been observed recently. This study examined how the smoking behaviour of male adults changed with age after the implementation of national tobacco control policies in 1995. STUDY DESIGN: Repeated cross-sectional study using a national survey. METHODS: Data were obtained from the 1992, 1995, 1999, 2003 and 2006 results of a repeated cross-sectional survey, the Social Statistics Survey. The smoking status of adult men was compared before (1992 and 1995 surveys) and after (1999, 2003 and 2006 surveys) the implementation of government-directed tobacco control policies using graphical methods and logistic regression analysis. RESULTS: After the implementation of tobacco control policies, the percentage of current male smokers decreased while the percentage of former smokers increased markedly. Smoking prevalence among older men (aged 50 years or more) reduced initially, and this decline was more pronounced after the tobacco control policies were implemented. Smoking prevalence in younger men (aged 30-49 years) declined in 2003 when more comprehensive tobacco control policies were implemented. CONCLUSIONS: This study suggests that comprehensive tobacco control policies in South Korea reduced smoking prevalence among males, initially among older men and later among both older men and younger men.

A 57-year-old right-handed man presented with speech disturbance 1 day prior to his admission. The standardized aphasia test batteries showed transcortical sensory aphasia. MRI revealed a left frontal and insular infarct. Positron emission tomography scans also revealed a glucose hypometabolism in the same region as the infarcted area on MRI. Repeated aphasia testing showed that his aphasia only partially improved.

We report the first case of subcutaneous hyalohyphomycosis caused by the genus Cephalotheca, which has not been reported to cause human infection. A 67-year-old immunocompetent farmer presented with a 10-year history of verrucous erythematous plaques on the right foot dorsum, great toe, heel and sole. Histopathology of the lesions revealed chronic granulomatous inflammation with numerous nonpigmented fungal spores in the dermis. Cultures of biopsy specimens on Sabouraud's dextrose agar for 2 weeks developed into yellowish brown, velvety colonies that subsequently turned black after 8 weeks because of the production of black cleistothecia indicating the teleomorph. On the basis of mycological features, scanning electron microscopic morphology and molecular analysis data, a new species of Cephalotheca was identified and designated Cephalotheca foveolata. Because there was no response to the antifungal agents administered, the patient was successfully treated by surgical excision with skin graft.
