OBJECTIVE: The aim of the present study was to provide clinical consensus and evidence regarding initial treatment strategies for the pharmacological treatment of social anxiety disorder (SAD) in Korea. METHODS: We prepared a questionnaire to derive a consensus from clinicians regarding their preference for the pharmacological treatment of SAD in Korea. Data regarding medication regimens and psychotropic drugs used during initial treatment, the doses used, and the pharmacological treatment duration were obtained. Responses were obtained from 66 SAD experts, and their opinions were classified into three categories (first-line, second-line, third-line) using a chi-square analysis. RESULTS: Clinicians agreed upon first-line regimens for SAD involving monotherapy with selective serotonin reuptake inhibitors (SSRIs) or the serotonin-norepinephrine reuptake inhibitor (SNRI) venlafaxine, or combined therapy using antidepressants with betablockers or benzodiazepines on a standing or as-needed basis. First-line psychotropic drug choices for initial treatment included the following: escitalopram, paroxetine, sertraline, venlafaxine, and propranolol. The medication dosage used by domestic clinicians was found to be comparable with foreign guidelines. Domestic clinicians tended to make treatment decisions in a shorter amount of time and preferred a similar duration of maintenance treatment for SAD when compared with foreign clinicians. CONCLUSION: This study may provide significant information for developing SAD pharmacotherapy guidelines in Korea, especially in the early stage of treatment.

PURPOSE: Emerging evidence indicates that runt-related transcription factor 3 (RUNX3) is an important tumor suppressor gene in several cancer types, including colorectal cancer (CRC). However, the clinical significance of RUNX3 inactivation in CRC remains unclear. The aim of this study was to examine the correlation between clinicopathologic factors and RUNX3 hypermethylation/expression in CRC. METHODS: Sixty-two CRC patients who were treated at the Soonchunhyang University College of Medicine were recruited in this study. The hypermethylation of CpG islands in the RUNX3 promoter and the expression of RUNX3 mRNA were identified by methylation-specific polymerase chain reaction (PCR) and reverse transcriptase-PCR, respectively. The expression of RUNX3 was determined by immunohistochemical staining. RESULTS: Of the 62 CRC tissue samples, 20 (32.3%) presented hypermethylated RUNX3 promoters. Aberrant RUNX3 hypermethylation was found to be associated with vascular (P = 0.006) and lymphatic (P = 0.002) invasion. Hypermethylation of RUNX3 was associated with poor survival outcomes (P = 0.038). However, expression of RUNX3 was not a prognostic factor (P = 0.363). CONCLUSION: Hypermethylation of RUNX3 may be a predictor of a poor prognosis in CRC.

Arachnoid cysts (AC) are intraarachnoidal cerebrospinal fluid collections, and account for 1% of all intracranial space-occupying lesions. Intracystic hemorrhage of the AC can occur spontaneously, but this is an extremely rare event. Herein, we present a case of hemorrhagic AC in a nontraumatic patient in the left middle cranial fossa. We also performed relevant literature review on this disease.

BACKGROUND AND OBJECTIVES: The transplantation of human umbilical cord blood cells (hUCBCs) has been shown to attenuate the unregulated activation of microglia in a rat model of cerebral palsy (CP). To investigate whether hUCBCs transplantation is also anti-inflammatory in humans, we performed a clinical trial in patients with CP. METHODS AND RESULTS: Allogeneic or autologous hUCBCs and erythropoietin (EPO) were intravenously injected into human patients with CP (mean age of approximately 38 weeks), and patients were analyzed for their motor function and social behavior. Blood samples were tested for cytokine levels. The most surprising finding in the study was that the cytokine levels were dependent on the donor cell source (allogeneic or autologous). Interestingly, the allogeneic treatment group demonstrated significantly decreased levels of pro-inflammatory factors, such as IL-1alpha, IL-6, TNF-beta, and RANTES, and showed a statistically significant improvement in motor and social behavior compared to the autologous treatment group. CONCLUSIONS: Given that inflammation plays a pivotal role in CP, our results suggest that allogeneic hUCBCs therapy may be an appropriate strategy for CP treatment. In addition, prior to transplantation, a detailed analysis of the amount of proinflammatory cytokines in cord blood may be needed to avoid exacerbating inflammatory responses.

BACKGROUND: Although echocardiography is usually used for quantitative assessment of left ventricular function, the recently developed 16-slice multidetector computed tomography (MDCT) is not only capable of evaluating the coronary arteries but also left ventricular function. Therefore, the objective of our study was to compare the values of left ventricular function quantified by MDCT to those by echocardiography for evaluation of its regards to clinical applications. MATERIAL AND METHOD: From 49 patients who underwent MDCT in our hospital from November 1, 2003 to January 31, 2005, we enrolled 26 patients who underwent echocardiography during the same period for this study. Left ventricular end-diastolic volume index (LVEDVI), left ventricular end-systolic volume index (LVESVI), stroke volume index (SVI), left ventricular mass index (LVMI), and ejection fraction (EF) were analyzed. RESULT: Average LVEDVI (80.86+/-34.69 mL for MDCT vs 60.23+/-29.06 mL for Echocardiography, p<0.01), average LVESVI (37.96+/-24.52 mL for MDCT vs 25.68+/-16.57 mL for Echocardiography, p<0.01), average SVI (42.90+/-15.86 mL for MDCT vs 34.54+/-17.94 mL for Echocardiography, p<0.01), average LVMI (72.14+/-25.35 mL for MDCT vs 130.35+/-53.10 mL for Echocardiography, p<0.01), and average EF (55.63+/-12.91 mL for MDCT vs 59.95+/-12.75 mL for Echocardiography, p<0.05) showed significant difference between both groups. Average LVEDVI, average LVESVI, and average SVI were higher in MDCT, and average LVMI and average EF were higher in echocardiogram. Comparing correlation for each parameters between both groups, LVEDVI (r(2)=0.74, p<0.0001), LVESVI (r(2)=0.69, p<0.0001) and SVI (r(2)=0.55, p<0.0001) showed high relevance, LVMI (r(2)=0.84, p<0.0001) showed very high relevance, and EF (r(2)=0.45, p=0.0002) showed relatively high relevance. CONCLUSION: Quantitative assessment of left ventricular volume and function using 16-slice MDCT showed high relevance compared with echocardiography, therefore may be a feasible assessment method. However, because the average of each parameters showed significant difference, the absolute values between both studies may not be appropriate for clinical applications. Furthermore, considering the future development of MDCT, we expect to be able to easily evaluate the assessment of coronary artery stenosis along with left ventricular function in coronary artery disease patients.

OBJECTIVES: To investigate the therapeutic compliance and its related factors in lung cancer patients. METHODS: The subjects of this study comprised 277 patients first diagnosed with lung cancer at Kyungpook National University Hospital between Jan 1999 and Sept 1999. Of these, 141 (50.9%) participated in the study by properly replying to structured questionnaires. The data was analyzed using a simplified Health Decision Model. This model includes categories of variables covering therapeutic compliance, health beliefs, patient preferences, knowledge and experience, social interaction, sociodemographic and clinical characteristics. RESULTS: The therapeutic compliance rate of the 141 study subjects was 78.0%. An analysis of health beliefs and patient preferences revealed health concern (p<0.05), dependency on medicine (p<0.05), perceived susceptibility and severity (p<0.05) as well as preferred treatment (p<0.01) as factors related to therapeutic compliance. Factors from the sociodemographic characteristics and clinical factors that were related to therapeutic compliance were age (p<0.01), monthly income (p<0.05), histological type (p<0.05) and clinical stage (p<0.05) of cancer. CONCLUSIONS: In order to improve therapeutic compliance in lung cancer patients it is necessary to educate the aged, low-income patients, or patients who have small cell lung cancer or lung cancer of an advanced stage for which surgery is not indicated. Additionally, it is essential for medical personnel to have a deep concern about patients who have poor lifestyles, a low dependency on medicine, or a high perceived susceptibility and severity. Practically, early diagnosis of lung cancer and thoughtful considerations of low-income patients are important. By means of population-based education in a community, we may promote attention to health and enhance the early diagnosis of lung cancer.

BACKGROUND: Non-small lung cancer(NSCLC) develops as a result of the accumulation of multiple genetic abnormalities. Loss of heterozygosity(LOH) is one of the most frequent genetic alterations that is found in NSCLC, and the chromosomal regions that display a high rate of LOH are though to harbor tumor suppressor genes(TSGs). This study was done to determine the frequency of LOH in 21q with the aim of identifying potential TSG loci. METHOD: Thirty-nine surgically resected NSCLCs were analysed. Patietns peripheral lymphocytes were used as the source of the normal DNA. Five microsatellite markers of 21q were used to study LOH : 21q21.1(D21S1432, and D21S1994) ; 21q21.2-21.3(D21S1442) ; 21q22.1(21S1445) ; and 21q22.2-22.3(D21S266). The fractional allelic loss(FAL) in a tumor was calculated as the ratio of the number of markers showing LOH to the number of informative markers. RESULT: LOH for at least one locus was detected in 21 of 39 tumors(53.8%). Among the 21 tumors with LOH, 5(21.8%) showed LOH at almost all informative loci. Although statistically not significant, LOH was found more frequently in squamous cell carcinomas(15 of 23, 65.2%) than in adenocarcinomas(6 of 16, 37.5%). In the squamous cell carcinomas the frequency of LOH was higher in stage II-III (80.0%) than in stage I (53.8%). The FAL value in squamous cell carcinomas(0.431±0.375) was significantly higher than that found in adenocarcinomas(0.192±0.276). CONCLUSION: These results suggest that LOH on 21q may be involved in the development of NSCLC, and that TSG(s) that contribute to the pathogenesis of NSCLC may exist on 21q.

Secondary hyperparathyroidism is the condition which leads to excessive production of the parathyroid hormone secreted to compensate for longstanding hypocalcemia in chronic renal failure. After restoration of normal renal function, some patients continue to have autonomous parathyroid hyperfunction. In 1963 St. Goar termed it tertiary hyperparathyroidism. Hyperparathyroidism in the chronic renal failure is mostly well managed medically, but sometimes may require surgical intervention in refractory hyperparathyroidism. Recently, we have experienced a female patient diagnosed as tertiary hyperparathyroidism with persistent hypercalcemia after renal transplantation and report the results of subtotal parathyroidectomy and thyroid right lobectomy due to hyperparathyroidism and thyroid papillary carcinoma found coincidentally.

BACKGROUND: In patients with chronic obstructive pulmonary disease(COPD), several factors have been associated with a poor prognosis. These include old age, low FEV, low diffusing capacity, high alveolar-arterial oxygen pressure difference, and finally cor pulmonale. This study was done to investigate in the ECG signs suggesting cor pulmonale were independent prognostic factors in patients with COPD. METHOD: We analyzed ECG, pulmonary function data and arterial blood gas values in 61 patients who were admitted through the emergency department with an acute exacerbation of COPD. The ECG signs reflecting cor pulmonale were right atrial overloading(RAO), right bundle branch block, right ventricular hypertrophy and low-voltage QRS. The 61 patients were divided into 2 groups, group I with no ECG signs(n=36) and group II with one or more ECG signs(n=25) suggesting cor pulmonale. RESULTS: Poor prognostic factors by univariate analysis were low FEV1, FEV1 % pred., VC% pred., DLco, DLco % pred., PaO2 and SaO2 high PaCO2 presence of ECG signs reflecting cor pulmonale, presence of mental status change, use of mechanical ventilator, and long tern use of glucocorticoid. A multivariate analysis indicated that age(risk ratio=1.13, 95% confidence interval 1.05~1.23), Dlco % pred. (risk ratio=0.97, 95% confidence interval 0.94~0.99), PaO2 (risk ratio=0.95, 95% confidence interval 0.90~0.99) and RAO(risk ratio=5.27, 95% confidence interval 1.40~19.85) were independent prognostic factors of survival. There was a significant difference in survival between the patients with and without RAO(p=0.038). The survival rates at 1, 2, and 5 years were 94.5%. 81.4%, and 50.0% in patients without RAO and 82.4%, 70.6%, and 27.5% in patients with RAO, respectively. CONCLUSION: These results suggest that the presence of ECG signs reflecting cor pulmonale is a predictor of survival and that RAO of these ECG signs is a significant independent predictor of survival in patients with COPD.
