ABSTRACT
OBJECTIVES: We review the sleep problems of the alcohol dependence patients. Especially we are interested in the prevalence, the severity of symptoms, anxiety, depression, and sleep quality of restless legs syndrome (RLS) in the alcohol dependence patients. METHODS: We recruit 86 alcohol dependence patients who were admitted from October 6th, 2008 to October 17th, 2008. We interviewed each patient and evaluated sleep questionnaires such as the Sleep Disorder Questionnaire (SDQ), the Pittsburgh Sleep Quality Index (PSQI) and the International Restless Legs Syndrome Study Group (IRLSSG) rating scale. The presence of RLS and its severity were assessed using the IRLSSG diagnostic criteria and the IRLSSG severity scale, respectively. Depression and anxiety were evaluated by the Beck Depression Inventory (BDI) and the Beck anxiety inventory (BAI). RESULTS: Of all 86 patients, 59 patients have insomnia, 33 patients have RLS, 30 patients have Periodic limb movement disorder (PLMD), 29 patients have nightmare. RLS patients have more high score in the BAI (21.70+/-10.36 vs 14.67+/-11.98), and their sleep quality was poor in the PSQI (11.09+/-4.08 vs 7.92+/-3.91) than non-RLS patients. CONCLUSION: This study shows that alcohol dependence patients show many sleep problems such as insomnia and RLS. So we should notice that the sleep problems of alcohol dependence patients are important in clinical approach and treatment.

Malaria is still a major health problem in Thailand and its incidence is currently rising in Korea. To identify a useful antigen for the diagnosis of malaria patients, a cDNA expression library from malaria parasites was constructed and screened out immunologically. One clone was selected in view of its predominant reactivity with the patient sera. The recombinant malaria parasite antigen (Pv30) with 27 kDa as a C-terminal His-tag fusion protein that was produced in Escherichia coli was identified through immunoblot analysis. The deduced amino acid sequence had the sequence homology with the merozoite surface protein 1 (MSP1) genes of Plasmodium falciparum and P. yoelii, each by 41% and 42%, respectively. Measurement of serum IgG and IgM antibody to Pv30 by enzyme-linked immunosorbent assay (ELISA) was evaluated as a serodiagnostic test for malaria patients in Thailand (endemic area) and Korea (recently reemerging area). The sensitivity of P. vivax, P. falciparum, and P. malariae was 96.3% (26 /27), 90.6% (29/32), and 100% (6/6), respectively, and the specificity was 63.5% (40/63) in Thailand samples. The sensitivity of P. vivax was 98.8% (88/89), and the specificity was 96.6% (86/89) in Korean samples. Pv30 appears to be a good and reliable recombinant antigen for serodiagonosis of malaria in a nonendemic area.
