Peutz-Jeghers syndrome(PJS) is a relatively rare autosomal-dominant disease characterized by the occurrence of extensive mucocutaneous hyperpigmentation and gastrointestinal polyps. PJS patients are considered to have a high prevalence of intussusception due to polyps. We report the radiological findings in two cases of intussusception due to polyps in patients with PJS, and review the literature.

OBJECTIVE: The purpose of this study was to evaluate the effect of tele-health service on knowledge and family support of hypertension patients. METHODS: The subjects were two hundred thirty seven primary hypertension patients who were enrolled at health care center located at the cities of Chunchon, Wonju, and Kangreung, Kwangwon-Do. Tele-health system were located health care center of each cities and the service had been provided for three months. Tele-health system called patients every morning to remind them of taking the prescribed medicine by a 12.5 second pre-recorded message. In addition, tele-health system informed the patients of knowledges on hypertension(medication, exercise, nutrition, regular examination) by 18.4 through 25.3 second pre-recorded message during weekend. Data were collected using a questionnaire before and after the service. RESULTS: The differences of knowledge on hypertension before and after tele-health service was significant(t=-7.908, p=.000). Family support before and after the service was statistically significant as well(t=-7.550, p=.000). CONCLUSION: Tele-health service was effective to manage hypertension.

BACKGROUND: As a leading cause of death in Korea, cancer is known to be related to lifestyle including diet. In 2007, the World Cancer Research Fund announced 10 evidence-based guidelines for reducing the number of cancers. The purpose of this paper was to produce guidelines specific to and relevant to the people of Korea. METHODS: Ranging over 6 categories, 15 dietary factors known to be associated with cancers were selected after reviewing the results of relevant researches including Korean subjects and evidence-based research documents regarding the relationships between cancer and diet. The levels of intake of these selected dietary factors by Koreans were compared to the established dietary guidelines and detailed practices for cancer prevention. RESULTS: The Korean dietary guidelines for cancer prevention consists of 8 detailed recommendations along with multiple specific practices based on the analyses of data and documents on weight and intake of cereals, fruits, vegetables, meat, salt, dairy products, alcohol, and nutrient supplements. CONCLUSIONS: The Korean dietary guidelines for cancer prevention were established based on valid scientific approach by analyzing the most recent available data. For some dietary factors, however, sufficient analysis for intake levels in Koreans was not possible. Therefore, fundamental data for the establishment of national strategy and for guideline amendments for preventing cancers need to be gathered through the analyses of relationships between cause and deaths due to cancer, database reinforcement, additional research including Korean subjects, and assessment of usual intake.

OBJECTIVES: Cognitive behavioral therapy of schizophrenia has been developed as a psychological therapy for drug resistant patients with schizophrenia. However, there are some controversial issues regarding the size and mode of the therapeutic effect. The aim of this study is to compare the effect of cognitive behavioral therapy with supportive therapy after treatment. METHODS: Patients with drug resistant schizophrenia were randomly allocated, and stratified according to two mental health institutes to two different therapy groups. We used four assessment scales to evaluate residual symptoms of patients in detail. Patients were assessed twice by a blind rater, at baseline and after treatment. RESULTS: No significant differences in the change of PANSS (Positive and Negative Syndrome Scale) scores were observed between the cognitive behavioral therapy and supportive therapy groups at one month after treatment. There was no significant difference in change of K-PSYRATS (Korean-Psychotic Symptom Rating Scale)-Delusion score, however, a trend toward significance in K-PSYRATS - Hallucination was observed between the two groups. In the aspect of insight, a significant difference in the change of SDMD-K (The Scale to assessment Unawareness of Mental Disorder-Korean version) score was observed between the two groups after treatment. CONCLUSION: Despite remarkable development of pharmacotherapy for schizophrenia, many patients still suffer from residual symptoms. Findings of this study showed that cognitive behavioral therapy can improve the insight of patients and reduce the severity of residual positive symptoms, especially hallucination. Cognitive behavioral therapy should be practiced effectively in the psychiatric clinic and community mental health system.

Background: Lipid emulsion (LE) is effective in treating intractable cardiac depression induced by the toxicity of highly lipid-soluble drugs including local anesthetics. However, the effect of LE on chloroquine (CQ)-evoked cardiac toxicity remains unclear. This study aimed to examine the effect of Lipofundin MCT/LCT, an LE, on the cardiotoxicity caused by CQ in H9c2 rat cardiomyoblasts and elucidate the underlying cellular mechanism. Methods: The effects of CQ (1 × 10-4 M), LE, and the reactive oxygen species (ROS) scavengers mitotempo and N-acetyl-L-cysteine (NAC), alone or combined, on cell viability and migration, apoptosis, ROS production, calcium levels, mitochondrial membrane potential, and adenosine triphosphate (ATP) were examined. Additionally, the effects of LE on the activities of catalase (CAT), malondialdehyde (MDA), and superoxide dismutase (SOD) induced by CQ were assessed. Results: Pretreatment with LE, mitotempo, or NAC reversed the reduction in cell migration and viability, mitochondrial membrane potential, and ATP levels evoked by CQ, and inhibited the increase in cleaved caspase-3, ROS, and calcium concentration induced by CQ. LE inhibited the increase in Bax expression, terminal deoxynucleotidyl transferase dUTP nick end labeling-positive cells, MDA activity, and late apoptosis, and reversed the reduction in SOD and CAT activity induced by CQ. CQ did not significantly affect cleaved caspase-8 expression, and LE did not significantly affect CQ concentration. Conclusions Collectively, these results suggest that LE (Lipofundin MCT/LCT) inhibits the cardiotoxicity and late apoptosis induced by CQ toxicity via the intrinsic mitochondrial apoptotic pathway that is associated with direct inhibition of ROS production.

BACKGROUND/AIMS: Recent studies have shown that the genotype of hepatitis B virus (HBV) may correlate with the disease natural history and treatment outcome. However, several of these studies used low sensitivity assays in a small number of patients, and this has precluded an accurate evaluation of Korean HBV genotypes. We analyzed Korean HBV genotypes in a large population by employing a new technology, restriction fragment mass polymorphism (RFMP) using MALDI-TOF mass spectrometry, in a sensitive and specific manner. METHODS: Between February 1995 and December 2003, a total of 475 patients with chronic HBV infection were enrolled. The assay is based on the mass measurement of oligonucleotides having genotypic variations of the S gene. Clinical features including the virologic status and disease progression were also evaluated. RESULTS: The median age of the total patients was 35.5 years. Out of 475 patients, there were 162 (34.1%) inactive carriers, 172 (36.2%) had chronic hepatitis, 77 (16.2%) had liver cirrhosis and 64 (13.5%) had hepatocellular carcinoma (HCC). There were 454 patients (95.6%) with genotype C, 4 patients (0.8%) with genotype A, 16 patients (3.4%) with the mixed A and C genotype [7 patients (1.4%) with AA], and 1 patient (0.2%) with B genotype. Comparing genotype A and C, genotype A patients were all inactive carriers without HCC, whereas genotype C patients included those with chronic hepatitis, liver cirrhosis and HCC. CONCLUSIONS: HBV genotype C is highly prevalent in Korea. Although it is a small percentage, genotype A also exists and it seems to take a more benign clinical course than genotype C. Further studies are necessitated to assess the relationship between HBV genotypes and the various aspects of the diseases' clinical course.

BACKGROUND: Topical 5% minoxidil solution stimulates new hair growth and it helps stop the loss of hair on individuals with androgenetic alopecia (AGA). OBJECTIVE: We wanted to assess the efficacy and safety of topical 5% minoxidil solution for treating Korean men with AGA. METHODS: This was a 24-week, open label, clinical trial that was conducted at 14 university dermatologic centers nationwide throughout South Korea as a multicenter study of the Korean Hair Research Society. The eligible subjects for this study were 18- to 65 year-old men with androgenetic alopecia, as defined by the Norwood scale as type III vertex, IV and IVA. A total of 175 men (20~62 years old) with AGA applied topical 5% minoxidil solution twice daily. Efficacy was evaluated by 1) the total hair count per 1 cm2 and 2) the mean hair diameter and 3) the patient assessment and 4) the investigator assessment of the change in scalp coverage and the benefit of treatment. RESULTS: At week 24 as compared with baseline, there was a statistically significant increase in the total hair counts and the mean hair diameter (p<.0001). Topical 5% minoxidil solution helped improve the investigator and patient assessments. The topical 5% minoxidil solution was well tolerated over a 24-week period. CONCLUSION: We believe that topical 5% minoxidil solution is a safe and effective drug for Korean men with AGA.

BACKGROUND: Androgenetic alopecia (AGA) is a common hair loss disease with genetic predisposition among men and women, and it may commence at any age after puberty. It may significantly affect a variety of psychological and social aspects of one's life and the individual's overall quality of life (QoL). OBJECTIVE: This study aimed to investigate the QoL of AGA patients and discover the factors that can influence the QoL of AGA patients, including previous experience in non-medical hair care, reasons for hospital visits, age, duration, and the severity of AGA. METHODS: A total of 998 male patients with AGA were interviewed, using the Hair Specific Skindex-29 to evaluate the QoL of AGA patients. RESULTS: The results of the Hair Specific Skindex-29 on patients with AGA were as follows: symptom scale: 26.3+/-19.5, function scale: 24.0+/-20.1, emotion scale: 32.1+/-21.8, and global score: 27.3+/-19.1. According to this assessment, QoL was more damaged if the patient had severe alopecia, a longer duration of AGA, younger age, had received previous non-medical hair care, and visited the hospital for AGA treatment. CONCLUSION: This study showed that AGA could harmfully affect the patients' QoL. These findings indicate that dermatologists should address these QoL issues when treating patients with alopecia.

BACKGROUND/AIMS: Symptom-to-door time is associated with the prognosis for ST-segment elevation myocardial infarction. However, this value has not been a concern in patients with non-ST segment elevation myocardial infarction (NSTEMI). The aim of this study was to assess the relationship between symptom-to-door time and clinical outcomes in patients with NSTEMI. METHODS: In total, 1,971 patients with NSTEMI (64.8+/-12.1 years, 23.6% women) were enrolled between Nov. 2005 and Jan. 2008. The patients were divided into two groups according to the time difference between the presentation of symptoms and first medical contact: group I (<12 hours, n=1433) and group II (>12 hours, n=538). One-year mortality rates were compared between the groups. Thrombolysis In Myocardial Infarction (TIMI) and Global Registry of Acute Coronary Events (GRACE) risk scores were calculated in all study patients. RESULTS: The mean age was 64.4+/-12.2 years in group I and 65.6+/-12.0 years in group II (p=0.046). No significant differences existed between the two groups, except for the prevalence of hypertension, diabetes mellitus, initial systolic blood pressure, and initial serum creatinine levels. One-year mortality rates decreased significantly in group I patients [hazard ratio (HR)=1.35, 95% CI (confidential interval): 1.03~1.75, p=0.028] based on a multivariate Cox proportional analysis, which was adjusted by GRACE score, baseline characteristic variables, and predictors of a 1-year mortality in a univariate analysis. In intermediate-to high-risk patients (n=1,184, defined as having a TIMI risk score above 3 points), significant differences were observed in mortality rates between the two groups (HR=1.35, 95% CI: 1.02~1.80, p=0.037); the low-risk patients (n=787, HR=1.57, 95% CI: 0.80~3.05, p=0.188), however, showed no such differences. CONCLUSIONS: Symptom-to-door time was an independent long-term clinical predictor in patients with NSTEMI, especially in intermediate-to high-risk groups.

Objective: Pharmacotherapy including mood stabilizers and antipsychotics are frequently used in bipolar disorder (BD); however, the lack of consensus regarding the definition of polypharmacy hinders conducting comparative studies across different settings and countries. Research on Asian Prescription Pattern (REAP) is the largest and the longest lasting international collaborative research in psychiatry in Asia. The objective of REAP BD was to investigate the prescription patterns of psychotropic medications across Asian countries. The rates of polypharmacy and psychotropic drug load were also analyzed. Methods: The data collection was web-based. Prescription patterns were categorized as (1) mood stabilizer monotherapy: one mood stabilizer; (2) antipsychotic monotherapy: one antipsychotic; (3) simple polypharmacy: one mood stabilizer and one antipsychotic; and (4) complex polypharmacy: ≥ 2 mood stabilizers or/and antipsychotics. The psychotropic drug load in each patient was calculated using the defined daily dose method. Results: Among 2003 patients with BD (52.1% female, 42.4 years) from 12 countries, 1,619 (80.8%) patients received mood stabilizers, 1,644 (82.14%) received antipsychotics, and 424 (21.2%) received antidepressants, with 14.7% mood stabilizer monotherapy, 13.4% antipsychotic monotherapy, 48.9% simple polypharmacy, 20.3% complex polypharmacy, and 2.6% other therapy. The average psychotropic drug load was 2.05 ± 1.40. Results varied widely between countries. Conclusion Over 70% of psychotropic regimens involved polypharmacy, which accords with the high prevalence of polypharmacy in BD under a permissive criterion (2 or more core psychotropic drugs) worldwide. Notably, ≥ 80% of our sample received antipsychotics, which may indicate an increasing trend in antipsychotic use for BD treatment.
