OBJECTIVES: This study examined the effects of nutrition education and exercise therapies on the hematological status and diabetes knowledge of diabetic patients. For this purpose, a 12-week intensive management program was provided to diabetic patients participating in an exercise program in S health subcenter in Kwangju city and the effects were analyzed. METHODS: The subjects were 26 diabetic patients, who provided written informed consent. As a preliminary survey, this study examined the general characteristics, physical status, obesity, blood pressure, hematological status, daily activity level, diabetes knowledge, diet performance, and barriers to diet therapy. After the 12-week intensive management program was completed, a post-test was conducted in the same way as the preliminary test. The data were analyzed with using SPSS 18.0. The data from this study are presented as the mean ± standard deviation. A paired t-test was conducted to compare differences in the means before and after the program. Statistical significance was set to p < 0.05. RESULTS: The results of the program are presented as follows. The HDL-cholesterol levels changed from 39.8 ± 10.5 mg/dL to 48.3 ± 13.1 mg/dL, showing a significant increase (p < 0.001). The blood sugar 2 hours after a meal changed from 175.2 ± 67.1 mg/dL to 140.5 ± 42.5 mg/dL, showing a significant decrease (p=0.014). The glycosylated hemoglobin levels decreased significantly from 6.7 ± 1.1% to 6.3 ± 1.0% (p=0.010). The total scores of the daily activity levels increased significantly from 3.8 ± 2.4 to 4.8 ± 2.5 (p=0.040). The scores of knowledge on diabetes increased from 11.5 ± 3.6 to 14.0 ± 3.8 (p=0.001). The scores of knowledge on diet therapy changed from 6.7 ± 2.2 to 7.9 ± 1.7, showing a significant increase (p=0.027). CONCLUSIONS: The 12-week intensive management program intervened by nutrition education and exercise therapies induced positive changes to the HDL-cholesterol, blood sugar 2 hours after a meal, glycosylated hemoglobin, daily activity levels, and knowledge on diabetes.

A cyst is cavity occuring in either hard or soft tissue with a liquid, semiliquid material, or air content. It is surrounded by a definite connective tissue wall or capsule and usually has an epithelial lining. The contained substance is a predominant feature in proportion to the size of the entire mass of tissue. It was classified as odontogenic cyst and non-odontogenic cyst in origin. The anatomic distribution, clinical features, final diagnosis, and treatment methods are discussed.

PURPOSE: This study evaluated the prognostic differences in invasive cancer that progressed from a superficial transitional cell carcinoma (TCC) compared to an already invasive TCC at the time of the initial presentation. MATERIALS AND METHODS: Seventy-one patients who had a radical cystectomy performed for an invasive TCC were enrolled in this study. They were divided into two groups. In the first group, the patients were diagnosed as a superficial TCC at initially, which progressed to an invasive tumor. The second group consisted of patients who were diagnosed with invasive TCC at the time of the initial diagnosis. Two groups were compared with regard to the TNM stage, Ash grade, presence of accompanying carcinoma in-situ and survival rate. RESULTS: The group with invasive cancer at the time of the initial presentation had a significantly higher grade than the progressed group. The five-year survival rate was lower in the progressed group. Moreover, Kaplan-Meier analysis showed it was statistically significant (p=0.04). CONCLUSIONS: The grade was higher and the five-year survival rate was lower in the group with invasive cancer at the time of the initial presentation. Therefore, the invasive TCC at the initial diagnosis might take a more aggressive nature than the progressed group.

Anticancer effect of methanol extract of Caesalpinia sappan L. on oral carcinoma (KB) and osteosarcoma (HOS) cells were investigated in this study. In order to elucidate the anticancer mechanism of Caesalpinia sappan L, we analyzed telomerase inhibitory effect of the methanol extract of Caesalpinia sappan L. In addition we prepared 5 fraction samples according to its polarity differences and analyzed anticancer effects on oral carcinoma and osteosarcoma cells. Following results are obtained in this study. 1. 50% cell proliferation inhibitory value (IC50) of the methanol extract of Caesalpinia sappan L. against oral carcinoma (KB) cells and osteosarcoma (HOS) cells were 9.0 microgram/ml and 10.9 microgram/ml, respectively. 2. The methanol extract of Caesalpinia sappan L. showed inhibitory effect of telomerase which is required for cancer cell immortality. Therefore, it seems that the anticancer effect of methanol extract of Caesalpinia sappan is at least partially due to telomerase inhibitory effect. 3. Five fraction samples were prepared according to its polarity and 88.7% of ingredient of total methanol extract was transferred to ethylacetate fraction. Thin layer chromatography analysis showed that dichloromethane fraction contained ingredient with relatively high polarity and ethylacetate fraction contained similar ingredient found in total methanol extract. 4. Anticancer effect was observed in n-hexane, dichloromethane, and ethylacetate fractions. The highest anticancer effect was found in dichloromethane fraction which had IC50 value of 4.4 and>4.0 microgram/ml against oral carcinoma (KB) cells and osteosarcoma (HOS) cells, respectively.

Concurrent medical problem is common in dementia patients and critical to their care. Despite its importance, there was no bedside global rating scale for the seriousness of medical comorbidity. Lykestos et al. newly developed a reliable bedside scale, the General Medical Health Rating(GMHR). The objective of this study was to standardize the GMHR in form of Korean version(KGMHR). The study population consisted of 35 dementia patients in nursing home. Rating was performed by 1 physician and 2 nurses. Forty percent(14/35) of patients had one or more unstable medical illnesses. KGMHR ratings no more than 3 were 71.5%(25/35) of patients. The value of interrater reliability coefficient alpha was 0.9121. Correlations between KGMHR ratings and number of unstable medi-cal illnesses were high(r=-0.487, p<0.01). KGMHR ratings were also correlated with number of medications being taken for comorbid conditions(r=-0.542, p<0.01). In conclusion, KGMHR is a very reliable and simple rating scale for medical comorbidity in dementia patients. So the KGMHR could be a useful tool for evaluation of comorbidity in dementia patients. To verify the prognostic value of KGMHR, further large sized long-term study are needed.

BACKGROUND: This study was conducted to analyze the current problems in completing death certificates and to identify the correct method for completing death certificates. METHODS: We reviewed 262 death certificates in three hospitals from March 1 to April 30, 2000, and 119 death certificates in one hospital from March 1 to 31, 2000. We identified major and minor errors and analyzed and compared them retrospectively. RESULTS: A total of 381 death certificates were reviewed: 59 in Seoul National University Hospital, 101 in Ewha Woman's University Hospital, and 102 in Gachon Medical College Hospital, which has no education program for completing death certificates in postgraduate training, and 119 in Samsung Medical Center which has an education program for completing death certificates. 358 certificates(94.0%) had at least one error. There were only 23 death certificates(6.0%) without an error. In 182 cases(47.8%), there was one major error. In 321 death certificates(84.3%), there were more than two errors. A comparison of Samsung Medical Center with the other hospitals showed that the number of total errors was statistically different(p=0.001). CONCLUSION: There were few death certificates without an error in this study. In a hospital which has postgraduate training in completing death certificates, there are fewer errors than in other hospitals which have no training course. Emergency physicians actually certify many deaths, so they must know the correct method of completing death certificates for statistics on morbidity and mortality.

Anticancer effect of methanol extract of Caesalpinia sappan L. on oral carcinoma (KB) and osteosarcoma (HOS) cells were investigated in this study. In order to elucidate the anticancer mechanism of Caesalpinia sappan L, we analyzed telomerase inhibitory effect of the methanol extract of Caesalpinia sappan L. In addition, we prepared 5 fraction samples according to its polarity differences and analyzed anticancer effects on oral carcinoma and osteosarcoma cells. Following results are obtained in this study. 1. 50percent cell proliferation inhibitory value (IC(50)) of the methanol extract of Caesalpinia sappan L. against oral carcinoma (KB) cells and osteosarcoma (HOS) cells were 9.0 microgram/ml and 10.9 microgram/ml, respectively. 2. The methanol extract of Caesalpinia sappan L. showed inhibitory effect of telomerase which is required for cancer cell immortality. Therefore, it seems that the anticancer effect of methanol extract of Caesalpinia sappan is at least partially due to telomerase inhibitory effect. 3. Five fraction samples were prepared according to its polarity and 88.7percent of ingredient of total methanol extract was transferred to ethylacetate fraction. Thin layer chromatography analysis showed that dichloromethane fraction contained ingredient with relatively high polarity and ethylacetate fraction contained similar ingredient found in total methanol extract. 4. Anticancer effect was observed in n-hexane, dichloromethane, and ethylacetate fractions. The highest anticancer effect was found in dichloromethane fraction which had IC(50) value of 4.4 microgram/ml and > 4.0 microgram/ml against oral carcinoma (KB) cells and osteosarcoma (HOS) cells, respectively.

Objectives: The Panbio COVID-19 Ag Rapid Test Device (Panbio COVID-19 Ag, Abbott Rapid Diagnostics) is a lateral flow immunochromatographic assay targeting the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) nucleoprotein in nasopharyngeal specimens for the diagnosis of coronavirus disease 2019 (COVID-19). This study aimed to verify the performance of the Panbio COVID-19 Ag for implementation in clinical laboratories. Methods: Sixty nasopharyngeal swab specimens (30 positive and 30 negative) dipped in transport medium, and COVID-19 was confirmed using real-time RT-PCR using Allplex SARS-CoV-2 assay (Seegene), were tested using the Panbio COVID-19 Ag. Reproducibility was evaluated using positive and negative control materials. Sensitivity and specificity were calculated based on the results of realtime RT-PCR as the standard test method. Results: Reproducibility was confirmed by the consistent results of repeated tests of the quality control materials. The overall sensitivity and specificity of Panbio COVID-19 Ag were 50.0% and 100.0%, respectively. Panbio COVID-19 Ag demonstrated high sensitivity (88.2%) in analyzing the detection limit cycle threshold (Ct) value of 26.67 provided by the manufacturer as a positive criterion, and the sensitivity was 100.0% for the positive criterion of Ct values <25, although it was less sensitive for Ct ≥ 25. Conclusion Considering the high sensitivity for positive samples with Ct values <25 and the rapid turnaround of results, Panbio COVID-19 Ag can be used in clinical laboratories to diagnose COVID-19 in limited settings.

A 54-year-old man presented with primary position upbeat nystagmus and wall-eyed bilateral internuclear ophthalmoplegia. He also showed bilateral limb ataxia and impaired horizontal gaze. Upbeat nystagmus obeyed Alexander's law and attenuated by visual fixation and disappeared by convergence. Brain magnetic resonance imaging showed acute infarction in the bilateral paramedian midbrain involving the crossing of brachium conjunctivum. Multiple mechanisms including the interruption of central vestibulo-ocular projections from anterior canal may be postulated in upbeat nystagmus of this patient.
