The dopamine D4 receptor gene has a hypervariable segment in the coding region charcterized by a varying number of 48bp repeats in exon III of the gene. Varying the numbers of repeated segments may change the length, structure, and function of the receptor, which makes this gene a possible candidate for variations in dopamine-related behaviors. such as alcoholism and drug abuse. We evaluated the dopamine D4 receptor genotype in male alcoholics and normal controls. All alcoholics and controls were unrelated and from the Korean population. Genotype and allele frequencies in 67 alcoholics were compared to 67 controls who were free of alcohol abuse. substance abuse. and major mental illness. No association was found between the dopamin D4 recepto allele and alcoholism. This result indicate that there is no association of the dopamine D4 receptor with alcoholism in Korean. Further systemized investigation to determine the role of dopamine D4 receptor gene in alcoholism with a larger sample size will be required.

Alcohol has extensive effects on sleep and daytime sleepiness. Alcohol has a sleep inducing effect and the effect of increased non-REM sleep and suppressed REM sleep during the first half portion of night sleep, but alcohol induces the effect of decreased non-REM sleep and increased light sleep and frequent awakenings and REM rebound during the second half portion of night sleep. Alcohol provokes chronobiological change such as the changes of amplitude or the phase shifts of hormones or core body temperature. The sleep disruption resulting from alcohol drinking may lead to daytime fatigue and sleepiness. The elderly are at particular in the increased risk of alcohol-related sleep disorders because they achieve higher levels of alcohol in the blood and brain than do younger adults after consuming an equivalent dose. Bedtime alcohol consumption among older adults may lead to unsteadiness if walking is attempted during the night, with increased risk of falls and injuries. Continued alcohol use for sleep induction often induces aggravation of insomnia, alcoholism or sleep related breathing disorders such as obstructive sleep apnea. Alcohol should not be used as substitution of sleep pill because of the dependence and tolerance for sleep inducing effect, and the sleep disruption produced by alcohol withdrawal.

OBJECTIVE: This study was performed to determine the prevalence and age-adjusted prevalence of anti-HCV antibody among the employees and their partners in Korea, and whether prevalence varies with job type. METHOD: The blood serum of 29, 278 people, employees and their partners aged between 20 and 60 residing in Seoul or Kyung-gee province, were tested with Immunoradiometric Assay (IRMA) method using third generation anti-HCV serum. RESULTS: Twenty-five among the 29, 278 people tested positive; a prevalence rate of 0.9 per 1, 000 (95% CI 0.6-1.3). The prevalences of different age groups were 0, 0.5, 1.3, and 4.2 per 1, 000 among the subjects in their 20s, 30s, 40s and 50s respectively, which shows the increasing rate of prevalence with age. Age adjusted prevalence among employees was 1.3 per 1, 000. The prevalences among different kinds of job were 1.9 per 1, 000 (95% CI: 0.5~7.0) for construction, 1.7 per 1, 000 (95% CI: 0.7~3.9) for finance, and 1.2 per 1, 000 (95% CI: 0.2~6.6) for telecommunication. No significant statistical difference was found in the prevalence according to job type(p>0.05). CONCLUSIONS: Employees in Korea showed a lower prevalence rate of anti-HCV antibody than that of blood donors, health screening examinees and the general population. This result is in line with that of other studies abroad and is considered to be because employees may have lower rates of Hepatitis C risk activities, such as needle sharing, than unemployed.

OBJECTIVES: The course of Alzheimer's disease is often complicated by psychiatric symptoms including depression, delusion and hallucination. And these psychiatric symptoms may be due to neuropathological changes of the disease itself. This study examined whether psychiatric symptoms in Alzheimer's disease are associated with cerebral perfusion using single photon emission computed tomography (SPECT). METHODS: Supratentorial transaxial perfusion measurements were obtained in frontal, anterior temporal, posterior temporoparietal and occipital cortical areas in both hemispheres, in a baseline population of 29 mild to moderately impaired AD patients. We interviewed all the patients and their primary caregivers to assess their current and past psychiatric functioning. To compare the SPECT findings, all the patients were divided into two groups by presence of depression, delusion, hallucination and illusion, of which symptoms were explored separately. RESULTS: The patients with hallucination had hypoperfusion of both the posterior temporoparietal and the occipital regions of interest, compared with scans of the patients without hallucination. And in other symptom profiles, there was no difference in SPECT findings between the patients with symptoms and without symptoms. CONCLUSION: Psychotic patients with Alzheimer's disease had a pattern of cerebral perfusion deficits, which is different from that of nonpsychotic patients. This finding suggests that specific patterns of cerebral dysfunction probably be related to the specific psychiatric symptoms in Alzheimer's disease.

OBJECTIVES: Several studies suggest that psychotropic drugs may affect on lipid metabolism and body weight. And the differences of levels of seam lipids were observed in patients with several psychiatric disorders. Hence, in order to elucidate the effects of psychotropic drugs on serum lipid, lipoprotein and apolipoprotein, the authors estimated the serum lipid profile in the psych op harmacological treatment. METHODS: Thirty six patients with schizophrenia and 42 patients with depressive disorder or anxiety disorder were recruited from the inpatient psychiatric units and withdrawn from all psychotropic drugs at least far 3 months. The levels of seam total cholesterol, high-density lipoprotein cholesterol(HDL-C), trighlyceride, apolipoprotein A, apolipoprotein B, and lipoprotein(a) were measured before the treatment and after 2, 4, 8 and 12 weeks of the treatment. RESULTS: No statistically significant change was found on all serum lipid profiles in the antipsychotics group. However, the changes on serum total cholesterol, low-density lipoprotein (LDL-C), apolipoprotein A, and apolipoprotein B from the baseline to the following weeks have been observed in tricyclic antidepressants group. And the serum total cholesterol and apolipoprotein B have been observed to be changed from the baseline to the following weeks in the selective serotonin reuptake inhibitors poop. The changes on seam lipoprotein(a) were proved not to be statistically significant during all the psychotropic drugs treatment. CONCLUSION: These results implicate that all psychotropic drugs might affect on the lipid metabolism, especially for tricyclic antidepressants. Therefore, this implication could be important in clinical situation because the changes on serum lipid profiles may be related to the cardiovascular disease especially in psychiatric patients with the cardiovascular risk factor.

Dementia is one of the most common psychiatric problem in the elderly. According to the increase of the older people with dementia, management of dementia need to be systemized at the community level. The local center for dementia will be established for the community-based systematic and comprehensive management of dementia. It will be extended to all provinces of Seoul Metropolitan City. Activities of the local center for dementia includes 1) education, prevention, and public relations for dementia, 2) early detection and intervention for dementia, 3) establishment of effective, continuous, and personalized management system for the patient with dementia, 4) the development and promotion of community-based resources, 5) the construction of information and data related to dementia care system. This activity will increase the quality of life in the elderly with dementia and their caregivers. Finally, this management system for dementia may contribute to enhancement of the quality and the cost-effectiveness of community health promotion system for the older people.

Anxiety disorders are common psychiatric illnesses in the elderly. However, anxiety disorders in older people have not drawn much attention from researchers and clinicians alike, compared with late-life depression or dementia. The author searched for articles published from 1986 to 2006 using the key words including "anxiety", "elderly", "aged", and "pharmacological" therapy in the MEDLINE, PsychINFO, and KMbase in order to clarify effective pharmacological therapy in the elderly with anxiety disorders. Well designed studies for pharmacologic intervention in late-life anxiety disorders were rarely found. Nonetheless, studies on young adults demonstrated a number of pharmacological treatment options that can be applied to these patients. Pharmacologic treatments for the elderly include therapies using antideprssants, especially SSRI or SNRI, buspirone, or benzodiazepines. The latter requires special caution in the administration in the elderly because it can lead to adverse events. Therefore, well designed clinical trials are further needed to obtain optimal pharmacological intervention for the elderly with anxiety disorders.

OBJECTIVES: This study aims to analyze the association between the severity of sleep apnea, sleep and mood related scales, and activity during sleep in obstructive sleep apnea syndrome (OSAS) patients. METHODS: One hundred seventy six drug-free male patients confirmed as OSAS (average age=43+/-11 years) were selected through nocturnal polysomnography (NPSG). OSAS was diagnosed with apnea-hypopnea index (AHI) >5, mean AHI was 39.6+/-26.0. Sleep related scales were Stanford Sleepiness Scale (SSS), Epworth Sleepiness Scale (ESS), Pittsburg Sleep Quality Index (PSQI) and Morningness-Eveningness Scale (MES). Mood related scales were Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), State-Trait Anxiety Inventory (STAI) I, II and Profile of Mood States (POMS). NPSG was performed overnight with both wrist actigraphy (WATG). Parameters produced from WATG were total activity score, mean activity score and fragmentation index. We analyzed the correlation between each scale, AHI scored from NPSG and activity score analyzed from WATG. RESULTS: ESS showed significant positive correlation with PSQI, BDI, BAI and STAI I, II, respectively (p<0.01). SSS showed significant positive correlation with PSQI and BAI (p<0.05, p<0.01). BAI showed significant positive correlation with total activity score, mean activity score and fragmentation index (p<0.05, p<0.01, p<0.05). Total activity score showed significant positive correlation with ESS and BAI, respectively (p<0.05). Fragmentation index showed significant positive correlation with ESS, PSQI and BAI (p<0.05, p<0.01, p<0.05). AHI, indicator of sleep apnea is showed no significant correlation with each sleep and mood related scale. CONCLUSION: The degree of daytime sleepiness tends to be associated with night sleep satisfaction, depression and anxiety, and the activity during sleep rather than the severity of sleep apnea.

Thirty-two patients with transitional cell carcinoma of the renal pelvis and ureter were analyzed to determine whether there was any correlation between tumor characteristics and patient survival. The patients consisted of 26 male and 6 female. Patient age ranged from 12 to 80 years with a mean of 53.6 years. Of these patients. 28 were followed for 1 to 10 years. The most common presenting symptom was hematuria (87.5% ). Excretory urogram demonstrated NVK (nonvisualization or the kidney) in 16 patients and filling defect in 10. Pathologically. 31% of the patients were stage T1. 46% stage T2, 12% stage T3 and l6% stage T4. Histologically, 16% of the patients had grade I . 47% grade II and 37% grade III disease. Recently 6 patients, of whom 5 presented with stage T2 and 1 with stage T4. were treated postoperatively with adjuvant M-VAC (methotrexate, vinblastine. adriamycin and cisplantin) chemotherapy. H these 6 patients, 3 had subsequently recurrent tumor and their mean survival was 15 months. The 2 years survival rates of 28 patients follow-up were 90.0, 45.5, 33.3 and 0% for stage T1, T2, T3 and T4 disease, respectively, and 100, 66.7 and 10% for grade I to III disease, respectively. Overall 2 years and 5 years survival rates were 53.6% and 23.1% respectively. It is concluded from this study that age, sex. NVK on excretory urogram. synchronous or metachronous bladder tumors seem to have no influence on patient survival while patient survival correlates with stage and grade of tumor.
