OBJECTIVES: This study was carried out to evaluate the effects of industrial noise on blood pressure and heart rate. METHODS: Resting blood pressure, hearing loss, and general characteristics of the 102 subjects who were engaged in a factory in Pusan were measured from March to June for two years, in 1998 and 1999. With noise dosimeter, noise exposure level was measured from 8 A.M. to 4 P.M. Ambulatory blood pressure and heart rate were also measured every 30 minutes from 8 A.M. to 10 P. M. RESULTS: Controlling for age, smoking, and Quetelet's index, in subjects of under 40 years old exposed to higher than 85dBA, noise exposure and systolic blood pressure had a statistically significant correlation, and the same result was obtained in all subjects. The daily variability of ambulatory blood pressure and heart rate were observed in older than 40 years old group, but only heart rate in under 40 years old. CONCLUSIONS: The blood pressure and heart rate would be elevated when the workers exposed to noise. And in under 40 years old, the systolic blood pressure was elevated to the workers exposed to higher than 85dBA.

OBJECTIVES: With the elderly population rising sharply, there is a rising interest in dementia, and recently researches on risk factors for dementia, particularly of Alzheimer's disease have been actively conducted. The purpose of this research is to examine the effect of the late-onset depression as a risk factor for Alzheimer's disease. METHODS: The subjects were divided into the group of the patients who were diagnosed with depression in the National Health Insurance Corporation Ilsan Hospital from March 1, 2000 to December 31, 2009 and the corresponding control group, which was the group of the patients who were diagnosed with osteoarthritis for the same period. Of the above patients, the following cases were excluded from the final analysis. The excluded cases were those who were first diagnosed with either of the two diseases at the age of less than 50, and those who were diagnosed with major psychiatric disorder or neurologic disorder. As a result, a total of 5,347 people, made up of 1,697 depression patients and 3,650 osteoarthritis patients, were selected. Two groups were compared through survival analysis. RESULTS: Form the Log-Rank tests, it could be confirmed that there were significant differences (p<0.01) among the two groups. Even when many confounding factors including age and gender were controlled, the degree of occurrence of Alzheimer's disease was found to be higher in the group of late-onset depression patients than in the group of osteoarthritis patients (HR : 2.53-2.80). CONCLUSION: The late-onset depression can become independently the risk factor for Alzheimer's disease. Therefore it can be expected that the rate of occurrence of Alzheimer's disease may be reduced through active medical treatment of depression.

Although aseptic meningitis is a common neurological disorder, a combination of acute urinary retention and aseptic meningitis has been recognized rarely. To our knowledge, only a few case reports are available on this combination and the underlying pathology remains unclear. We reported on a patient showing acute urinary retention and aseptic meningitis with a review of the literatures.

The spectrum of neurological complications that occurs in the setting of HIV-1 infection includes AIDS-dementia complex, progressive multifocal leukoencephalopathy, brain lymphoma, toxoplasma encephalitis, and cryptococcal meningitis. We present a 36-year-old man with subacute multifocal neurologic signs who had a 3-year history of HIV-1 infection and a year history of left optic neuritis. The clinical presentation, CSF findings, and neuroradiological features in our patient were compatible with multiple sclerosis (MS), and hence he represented a rare case of HIV-related MS-like illness.

OBJECTIVES: Alcohol craving, is not only the most common symptom but the key element in alcohol dependence. The aim of this study is to measure ERPs, especially P3 elicted by alcohol related photographs in order to assess the craving in alcohol dependent patients. METHODS: Based on the result of previous study, 6 alcohol related photographs and 6 control photographs were chosen as visual stimuli. Each stimuli set consisted of alcohol related or control photographs as target stimuli and the same sized checkerboards as non-targets. Stimuli were presented using oddball paradigm for 300 msec with an inter-stimulus interval of 1000 msec in 12 normal controls and 16 abstinent alcohol dependent patients. One session consisted of three blocks; exercise block, control block, alcohol craving block. RESULTS: The amplitudes of P3 elicited by alcohol related visual stimuli were significantly larger than those of P3 elicited by control stimuli in alcohol dependent patients while there was no significant difference in normal controls. CONCLUSION: Consistent with the hypothesis, only alcohol-dependent patients were characterized by increased P3 amplitude associated with alcohol-realted visual stimuli compared with control stimuli. The results suggest the ERPs can be used as a neurophysiological correlate of alcohol craving in alcohol dependent patients. Future investigations will be needed to assess the relapse in the patients included in this study in order to elucidate the meaning of the increased P3 amplitude.

OBJECTIVES: This study is to examine the efficacy and the limitation of translated Korean version of the Obsessive-compulsive Drinking Scale. The Korean version of the scale is to be used for treatment and research on alcoholism. METHODS: This study was carried out to examine reliability and validity of the translated Korean version of the Obsessive-compulsive Drinking Scale. One hundred forty two out-patient alcohol dependence subjects were measured of their cognitive and behavioral aspects of craving with this scale. RESULTS: For 142 tested alcoholic subjects, internal consistency among 14 items of the Obsessive-compulsive Drinking Scale was 0.8947(Crohnbach's alpha). For 40 detoxified alcoholics, test-retest reliability of total score of the Korean version of the Obsessive-compulsive Drinking Scale was 0.76 (correlation coefficient, p<0.01). In 131 alcoholic subjects, validity of total score of the Korean version of the Obsessive-compulsive Drinking Scale was examined by correlation analysis with visual analogue scale (VAS). Correlation coefficient was 0.52 with VAS. Especially, correlation coefficient of compulsive subscale of the Korean version of the Obsessive-compulsive Drinking Scale was 0.61 with VAS. The total score of the Korean version of the Obsessive-compulsive Drinking Scale which was analyzed by repeated measure analyses of variance during 8 weeks was significantly different between the relapse group and the abstinence group. CONCLUSION: The Korean version of the Obsessive-compulsive Drinking Scale shows very similar psychometric performance to the original Obsessive-compulsive Drinking Scale developed by Anton. The Korean version, therefore, is an useful instrument that reflects characteristic drinking behaviors of alcoholics.

OBJECTIVES: Craving is the subjectively experienced motivational states inducing ongoing drug use in addicts. It also proceeds or precipitates relapse episode in drug addicts. Alcohol craving may be triggered by exposure to an object, environment, or emotion that a person has come to associate with alcohol consumption. Such stimuli are called alcohol-related cues. Among alcohol-related cues, alcohol-related visual stimuli are simple and reliable methods in inducing alcohol craving. The object of this study is to develop alcohol-related visual stimuli which induce alcohol craving reliably and to investigate the characteristics of alcohol-related visual stimuli in alcoholics. METHODS: First, the authors developed 27 alcohol and drinking color photos as candidate stimuli. Then, 3 photos which induce alcohol craving most were chosen as alcohol-related visual stimuli respectively by alcoholics, alcoholism high risk group and normal control group. The authors compared characteristics, situation and complexity of selected alcohol-related visual stimuli among three groups. RESULTS: 1) 'A glass of Soju', 'Drinking together' and 'A glass of beer, a bottle of beer and a sidedish' were chosen as alcohol-related visual stimuli which induce most craving in alcoholics, alcoholism high risk group and normal control group respectively. 2) Alcohol photo(stationary object) induced craving most in alcoholics in contrast with drinking photo(situation) in social drinkers. Alcoholics clung to alcohol per se, not to atmosphere or situation of drinking, and alcoholism high risk group felt craving by the expectation of drinking situation. Normal control group showed no consistent finding in choosing alcohol-related visual stimuli. CONCLUSION: With these results, the author suggests classical conditioning as psychopathological model of alcohol craving with alcoholics. In contrast with alcoholics, alcohol craving of alcoholism high risk group may be related to alcohol specific memory or positive expectancies about alcohol use. These finding may support different neurobiological mechanisms of alcohol craving between alcoholics and social drinkers.

Many researchers have used cue reactivity paradigm to study alcohol craving. But the difference of craving response to drinks between alcoholic patients and social drinkers was little evaluated. To investigate characteristics of alcohol-related visual cues which induce alcohol craving in alcoholism, we examined the response of subjects to alcohol-related cues considering qualitative aspects. The authors developed 27 photographs related to alcohol as candidate visual cues. Thirty five patients with alcohol dependence, 35 heavy drinkers and 35 social drinkers were shown these pictures and asked to rate these 6 pictures in order of inducing alcohol craving the most. 'A glass of Soju' and 'A Party scene' were chosen as the alcohol-related visual cues which induced craving the most in the patients and heavy drinkers, respectively. The results suggest that the patients with alcohol dependence are more absorbed by alcohol without drinking context such as an atmosphere or situation involving drinking. Heavy drinkers may experience craving in anticipation of being in a drinking situation.

Purpose:
The mean platelet volume (MPV) is regarded as a marker for thrombosis, atherosclerosis, and inflammation in various vascular diseases. However, it still remains unclear whether plasma MPV is associated with cerebral white matter hyperintensities (WMH) and cerebral microvascular pathology in the elderly population.
Materials and Methods:
We examined whether MPV level is associated with the presence of cerebral WMH on brain magnetic resonance imaging from 870 non-stroke outpatient subjects. The subjects were divided into three groups according to the consecutive level of MPV (low T1, middle T2, and high T3 MPV tertile groups). To determine the association of MPV levels with the WMH, logistic regression and receiver operating characteristic curve analyses were conducted.
Results:
Subjects with higher MPV level were older and more likely to have hypertension, diabetes mellitus, and low renal function. Cerebral WMH were more prevalent in subjects with higher MPV level. After adjusting for confounding factors, moderate to severe cerebral WMH were significantly associated with high MPV tertile level. This association remained significant after adjusting for other cerebral vascular pathologies. T2 [odds ratio (OR): 1.49, 95% confidence interval (CI): 1.03–2.15] and T3 MPV tertile groups (OR: 1.51, 95%CI: 1.04–2.20) had more cerebral WMH lesions compared to T1 MPV tertile group. In addition, the subjects with higher Fazekas scores showed higher MPV level (p=0.020).
Conclusion
We found that high MPV level is independently associated with cerebral WMH. This result suggests that platelet activation plays a role in the development of cerebral WMH.
