PURPOSE: To design novel balance tests to assess FAI and evaluate whether these tests are affected by BMI or gender, with the goal of developing reliable FAI assessment tests that are not influenced by these factors. MATERIALS AND METHODS: Participants included 20 young, healthy volunteers, 12 males and 8 females, with a mean age of 24+/-4 years and a mean BMI of 23+/-2.28. None of the subjects had known ankle instability. The following tests were assessed in each participant: single leg balance (SLB), percentage of leg press (PLP), single leg cycling (SLC), one leg squat (OLS), multiple direction reach-front/back/side (MDR-F/B/S), single leg hop (SLH), two leg jump (TLJ) and side step (SS). Data were analyzed using the SPSS 12.0 software program with ANOVA and t-test used. RESULTS: When grouped by BMI, we found that despite differences in BMI, the performances of all subjects were equivalent except for the one-leg-squat test, for which the mean ratios for underweight (1.69+/-0), normal weight (1.05+/-0.19), and overweight (0.93+/-0.30) individuals were significantly different (p=0.02); ratios for SLB (p=0.273), SLC (p=0.903), PLP (p=0.664), MDR-F/B/S (p=0.498, 0.908, and 0.503, respectively), SLH (p=0.332) were not significantly different. When calculated according to gender, we found that the OLS (p=0.013) and MDRS (p=0.034) were significantly different, while parameters for all the remaining tests were not affected. CONCLUSION: We found that the SLB, PLP, SLC, MDR-F/B, and SLH ratios were unaffected by BMI or sex and, therefore, are reliable parameters for assessing ankle instability.

We report a 63-years-old woman who developed a nodular lesion in right upper lobe (RUL) of lung after achieving a partial response with salvage chemotherapy for relapsed non-Hodgkin's lymphoma (NHL). Previously, she had been diagnosed as NHL and tuberculous lymphadenitis resulting a complete response with 8 cycles of CHOP regimen and anti-tuberculosis medication for 1 year. CT scan of the chest showed an irregular marginated soft tissue density in RUL with internal punctate calcifications and this lesion was difficult to discriminate between pulmonary tuberculosis and parenchymal involvement of NHL. Because the pulmonary infiltrations progressed despite empirical anti-tuberculosis medication, we performed bronchoscopic biopsy, showing diffuse large B-cell lymphoma. Thereafter, the pulmonary infiltrations were markedly improved with salvage chemotherapy. However, she died of refractory NHL despite high-dose chemotherapy with autologous peripheral blood stem cell transplantation.

PURPOSE: The purpose of this study was to analyze and assess the current situation of Korea's school health education program and to establish measures to efficiently carry out school health education in Korea. METHOD: The survey was conducted through the internet with the health educators of elementary, middle, and high schools nationwide to assess the current condition of school health education programs, and 2,459 samples were collected which accounted for 23.4% of the total respondents. RESULTS: According to school health educators on the enforcement of health education, the higher the education became, the less the health education was enforced. The enforcement rate was 96.9% in elementary schools, 76.7% in middle schools, and 67.3% in high schools. The major reasons were found as difficulty in securing class time (54.5%) and other excessive workloads (20.9%). As a result of the health education awareness survey, over 99% answered that health education is needed, over 80% answered that the education requires independent health textbooks, and over 95% answered that health educators are suitable for the person in charge of the education. CONCLUSION: This study will be a useful in establishing a detailed policy on enhancing school health education in the future.

Purpose: This study aimed to investigate the differences in sleep disturbance changes between patients receiving two hormone therapies (“tamoxifen plus ovarian function suppression group [T+OFS group]” versus “tamoxifen group [T group]”) and the chronological changes in sleep disturbances in each group. Methods: Premenopausal women with unilateral breast cancer who underwent surgery and were scheduled to receive hormone therapy (HT) with tamoxifen alone or with tamoxifen plus gonadotropin-releasing hormone (GnRH) agonist for ovarian function suppression were included. The enrolled patients wore an actigraphy watch for two weeks and completed questionnaires (insomnia, sleep quality, physical activity [PA], and quality of life [QOL]) at five time points: immediately before HT and 2, 5, 8, and 11 months after HT. Results: Among the 39 enrolled patients (21 and 18 patients in the T+OFS group and T group, respectively), 25 (17 and 8 patients in the T+OFS group and T group, respectively) were finally analyzed. There were no differences between the two groups in time-dependent changes in insomnia, sleep quality, total sleep time, rapid eye movement sleep rate, QOL, and PA;however, the severity of hot flashes was significantly higher in the T+OFS group than in the T group. Although the interaction between group and time was not significant, insomnia and sleep quality significantly worsened at 2–5 months of HT when changes over time were analyzed within the T+OFS group. In both the groups, PA and QOL were maintained without significant changes. Conclusion Unlike tamoxifen alone, tamoxifen plus GnRH agonist initially worsened insomnia and sleep quality, but gradually improved with long-term follow-up. Patients who initially experience insomnia during tamoxifen plus GnRH agonist administration can be reassured based on the results of this study, and active supportive care may be used during this period.

Rituximab is a chimeric monoclonal antibody that specifically targets the CD20 molecule on the B cell surface. Although rituximab was originally introduced for the treatment of lymphoid neoplasms such as non-Hodgkin's lymphoma (NHL) and chronic lymphocytic leukemia (CLL), it is now emerging as an effective and relatively safe therapeutic option for the patients with refractory immune thrombocytopenic purpura (ITP). We report here on a case of life-threatening toxic epidermal necrolysis (TEN) that was related with the use of rituximab in a patient with refractory ITP. The patient developed extensive erythematous papules and bullous lesions on his whole body associated with fever and visual disturbance during the second cycle of rituximab. The rituximab was discontinued and high dose intravenous immunoglobuline and steroid were administrated. Four weeks later, he fully recovered without any sequelae. A review of the literature reveals this to be the first reported case of TEN associated with rituximab injection in Korea.

Even though the Cox-Maze III procedure is the gold standard in the therapy for atrial fibrillation (AF) and its outcome is excellent, the complexity of the operation, longer cardiopulmonary bypass time and the risk of bleeding have tended to dissuade cardiac surgeons from its application. The recent data of the pathogenesis of AF and the development of alternative energy sources have facilitated the development of the modified Cox-Maze procedure rapidly. We reported that atrial fibrillation was conversed to sinus rhythm by the epicardial microwave ablation without cardiopulmonary bypass and the normal sinus rhythm was observed during 33 months of follow-up period.

BACKGROUND: There are several reports on outbreaks of V. paraphaemolyticus enteritis, however, these are only complicated cases or microbiologic surveillance in marine environment. We experienced an outbreak associated with eating flavored crabs and investigated the magnitude of the outbreak on a large scale located in Inchon. METHOD: We took medical history and stool cultures from patients with diarrhea, visited the Inha University Hospital from September 14 to September 30, 1998. Pulsed-field gel electrophereis of isolates from stool culture performed to identify the relation. We counted the number of diarrheal patients visited the emergency rooms of 5 other general hospitals and 9 private clinics in Inchon from August 16 to September 30, 1998. We bought 6 crabs and 2 flavored crabs at a nearby market and cooked 6 crabs flavored at our hospital. Cultures from the flavored crabs stored at a refrigerator were done daily for consecutive 5 days. RESULTS: The outbreak began on September 5 and ended on September 29, 1998. The numbers of patients visiting ERs of 6 general hospitals and private clinics during outbreak were estimated 1,033 and 4,530, respectively. All 8 crabs revealed Vibrio spp., but identification up to species level was not possible. Pulsed-field gel electrophoresis of 12 isolates showed different patterns and suggested different sources. CONCLUSION: In 1998, an outbreak estimated more than 5,000 patients of V. parahaemolyticus enteritis occurred in Inchon, Korea. Because the magnitude of food-associated enteritis is enormous, that surpass the number which we assumed from clinical practice, early report and prompt investigation of such cases are necessary.

This phase II study evaluated the efficacy and safety of combination chemotherapy with paclitaxel, cisplatin, and 5-fluorouracil (5-FU) in advanced gastric cancer. Patients with histologically confirmed gastric adenocarcinoma were eligible for the study. Paclitaxel (175 mg/m(2)) and cisplatin (75 mg/m(2)) were given as a 1-hr intravenous infusion on day 1, followed by 5-FU (750 mg/m(2)) as a 24-hr continuous infusion for 5 days. This cycle was repeated every 3 weeks. Forty-five eligible patients (median age, 56 yr) were treated in this way. Of the 41 patients in whom efficacy was evaluable, an objective response rate (ORR) was seen in 51.2% (95% CI, 0.35-0.67), a complete response in two, and a partial response in 19 patients. The median progression free survival was 6.9 months (95% CI, 5.86-7.94 months), and the median overall survival was 12.7 months (95% CI, 9.9-15.5). The main hematological toxicity was neutropenia and greater than grade 3 neutropenia was observed in twelve patients (54%). Febrile neutropenia developed in three patients (6.8%). The major non-hematological toxicities were asthenia and peripheral neuropathy, but most of patients showed grade 1 or 2. In conclusion, combination chemotherapy with paclitaxel, cisplatin, and 5-FU is a promising regimen, and was well tolerated in patients with advanced gastric cancer.

BACKGROUND: Accurate measurement of blood glucose concentrations is essential for defining diabetes, and the minimization of ex vivo glycolysis has been recommended. Recent guidelines advocate two kinds of methods for sample collection and processing: either the sodium fluoride (NaF) method or immediate refrigeration using a serum separation tube (SST). We investigated the difference between the two methods in measuring subsequent glucose concentrations using blood specimens from participants recruited for the fourth Korean National Health and Nutrition Examination Survey. METHODS: Paired venous blood samples were collected in an SST and a NaF tube from 1,103 men and women. SST serum was separated within 30 min, including standing for 15 min, and then refrigerated. The NaF samples were refrigerated, but not separated until immediately before analysis. We compared the blood glucose concentrations between the SST (SST glucose) and NaF (NaF glucose) methods. RESULTS: The mean SST glucose was significantly higher than NaF glucose (99.0 mg/dL vs 96.5 mg/dL, P<0.05). NaF glucose showed a negative mean bias of 2.6 mg/dL vs SST glucose but showed high correlation (R=0.9899). There was no significant correlation between the bias of blood glucose concentrations by two methods and the storage time of NaF glucose. CONCLUSIONS: The negative bias associated with the use of NaF tubes may significantly affect the prevalence of diabetes. Serum separation and refrigeration within 30 min after venous sampling is recommended over NaF method, not only to minimize the preanalytical impact on detecting diabetes but also to reduce sample volume and number of tubes.

We cloned the full-length cDNA of O Manisa, the virus for vaccinating against foot-and-mouth disease. The antigenic properties of the virus recovered from the cDNA were similar to those of the parental virus. Pathogenesis did not appear in the pigs, dairy goats or suckling mice, but neutralizing antibodies were raised 5-6 days after the virus challenge. The utilization of O Manisa as a safe vaccine strain will increase if recombinant viruses can be manipulated by inserting or removing a marker gene for differential serology or replacing the protective gene from another serotype.
