Cerebral white matter changes (WMCs) and silent brain infarcts (SBIs) are common radiologic findings in neurologically asymptomatic elderly people, but are associated with an increased risk of subsequent stroke. We investigated the prevalence and risk factors for these cerebral changes on brain computed tomography (CT) in 480 community-dwelling healthy Korean adults without stroke or dementia, who were recruited for an early health program. Cerebral WMCs were defined as the presence of approximately 5 mm wide ill-defined and moderately hypodense lesions, and SBIs were defined as the presence of >2 mm wide well-defined hypodense lesions. Of the 480 patients, 49 (10.2%) had cerebral WMCs and SBIs findings on brain CT. The prevalence of WMCs and SBIs increased with age: the prevalence was 2.4%, 9%, and 32% for subjects in their 50, 60s, and 70s, respectively. In addition, hypertension, abdominal obesity, increased levels of homocysteine and high sensitivity C-reactive protein were significantly associated with cerebral WMCs and SBIs. Our study suggests that regular monitoring of risk factors is required to prevent cerebral WMCs and SBIs and decrease the incidence of stroke and dementia in healthy individuals.

OBJECTIVES: To review the patterns of the dermatologic consultations of psychiatric adolescent inpatient and to explore the relationship between the dermatologic disorders and psychiatric disorders. METHODS: We retrospectively studied the data from 22 cases referred by psychiatric adolescent for a dermatologic consultation over 10 years in Daegu Catholic University Medical Center and compared with the data from 108 cases referred by the other department adolescent patients. RESULTS: The mean age of patients was 15.9. The male to female ratio was 1:1.44. The most common psychiatric and dermatologic disorder was major depressive disorder and acne, respectively. The most frequent reason for consultation was to ask for dermatologic disease or condition(54.5%) followed by to perform cosmetic procedure of patients need(40.9%) and to perform dermatologic test(4.6%). CONCLUSIONS: More than just a cosmetic disfigurement, dermatologic disorders are associated with a variety of psychopathologic problems that can affect the patient. Increased understanding of biopsychosocial approaches and liaison among psychiatrists and dermatologists could be beneficial.

OBJECTIVE: Little is known about the characteristic differences in alexithymic construct in various psychiatric disorders because of a paucity of direct comparisons between psychiatric disorders. Therefore, this study explored disorder-related differences in alexithymic characteristics among Korean patients diagnosed with four major psychiatric disorders (n=388). METHODS: Alexithymic tendencies, as measured by the Korean version of the 20-item Toronto Alexithymia Scale (TAS-20K), of patients classified into four groups according to major psychiatric diagnosis were compared. The groups consisted of patients with depressive disorders (DP; n=125), somatoform disorders (SM; n=78), anxiety disorders (AX; n=117), and psychotic disorders (PS; n=68). RESULTS: We found that substantial portions of patients in all groups were classified as having alexithymia and no statistical intergroup differences emerged (42.4%, 35.9%, 35.3%, and 33.3% for DP, SM, PS, and AX). However, patients with DP obtained higher scores in factor 2 (difficulties describing feelings) than those with SM or AX, after adjusting for demographic variables. CONCLUSION: These findings suggest that alexithymia might be associated with a higher vulnerability to depressive disorders and factor 2 of TAS-20K could be a discriminating feature of depressive disorders.

OBJECTIVES: This study was conducted to investigate the relationship between heat-related illnesses developed in the summer of 2012 and temperature. METHODS: The study analyzed data generated by a heat wave surveillance system operated by the Korea Centers for Disease Control and Prevention during the summer of 2012. The daily maximum temperature, average temperature, and maximum heat index were compared to identify the most suitable index for this study. A piecewise linear model was used to identify the threshold temperature and the relative risk (RR) above the threshold temperature according to patient characteristics and region. RESULTS: The total number of patients during the 3 months was 975. Of the three temperature indicators, the daily maximum temperature showed the best goodness of fit with the model. The RR of the total patient incidence was 1.691 (1.641 to 1.743) per 1degrees C after 31.2degrees C. The RR above the threshold temperature of women (1.822, 1.716 to 1.934) was greater than that of men (1.643, 1.587 to 1.701). The threshold temperature was the lowest in the age group of 20 to 64 (30.4degrees C), and the RR was the highest in the > or =65 age group (1.863, 1.755 to 1.978). The threshold temperature of the provinces (30.5degrees C) was lower than that of the metropolitan cities (32.2degrees C). Metropolitan cities at higher latitudes had a greater RR than other cities at lower latitudes. CONCLUSIONS: The influences of temperature on heat-related illnesses vary according to gender, age, and region. A surveillance system and public health program should reflect these factors in their implementation.
