PURPOSE: The purpose of this study was to investigate the feasibility and survival benefits of combined treatment with radiotherapy and adjuvant temozolomide (TMZ) in a Korean sample. MATERIALS AND METHODS: A total of 750 Korean patients with histologically confirmed glioblastoma multiforme, who received concurrent chemoradiotherapy with TMZ (CCRT) and adjuvant TMZ from January 2006 until June 2011, were analyzed retrospectively. RESULTS: After the first operation, a gross total resection (GTR), subtotal resection (STR), partial resection (PR), biopsy alone were achieved in 388 (51.7%), 159 (21.2%), 96 (12.8%), and 107 (14.3%) patients, respectively. The methylation status of O6-methylguanine-DNA methyltransferase (MGMT) was reviewed retrospectively in 217 patients. The median follow-up period was 16.3 months and the median overall survival (OS) was 17.5 months. The actuarial survival rates at the 1-, 3-, and 5-year OS were 72.1%, 21.0%, and 9.0%, respectively. The median progression-free survival (PFS) was 10.1 months, and the actuarial PFS at 1-, 3-, and 5-year PFS were 42.2%, 13.0%, and 7.8%, respectively. The patients who received GTR showed a significantly longer OS and PFS than those who received STR, PR, or biopsy alone, regardless of the methylation status of the MGMT promoter. Patients with a methylated MGMT promoter also showed a significantly longer OS and PFS than those with an unmethylated MGMT promoter. Patients who received more than six cycles of adjuvant TMZ had a longer OS and PFS than those who received six or fewer cycles. Hematologic toxicity of grade 3 or 4 was observed in 8.4% of patients during the CCRT period and in 10.2% during the adjuvant TMZ period. CONCLUSION: Patients treated with CCRT followed by adjuvant TMZ had more favorable survival rates and tolerable toxicity than those who did not undergo this treatment.

PURPOSE: Reactive oxygen species modulator 1 (Romo1) is a key mediator of intracellular reactive oxygen species production. However, examination of the clinical usefulness of Romo1 in cancers has been limited. We evaluated the association of Romo1 expression with clinical outcomes in advanced non-small cell lung cancer (NSCLC) patients treated with platinum-based chemotherapy. MATERIALS AND METHODS: Romo1 expression in tumor tissue was examined by immunohistochemistry and evaluated by histological score. Survival analyses were performed according to Romo1 expression and the association between Romo1 expression and clinical parameters was evaluated. RESULTS: A total of 88 tumor specimens were analyzed. Significantly shorter median progression-free survival (PFS) was observed in the high Romo1 group compared with the low Romo1 group (4.5 months vs. 9.8 months, p < 0.001), and the median overall survival (OS) of the high Romo1 group was also significantly shorter than that of the low Romo1 group (8.4 months vs. 15.5 months, p < 0.001). Results of multivariate analyses showed significant association of high Romo1 expression with both poor PFS (hazard ratio [HR], 2.75; 95% confidence interval [CI], 1.71 to 4.44) and poor OS (HR, 3.99; 95% CI, 2.36 to 6.74). Results of the subgroup analysis showed a similar association regardless of tumor histology. Romo1 expression showed no association with any clinical parameter including age, sex, smoking status, stage, differentiation, or tumor histology. CONCLUSION: Romo1 overexpression was associated with poor response to treatment and shorter survival in advanced NSCLC patients treated with platinum-based chemotherapy. Romo1 could be a potential adverse predictive marker in this setting.

A 46-year-old woman visited our hospital presenting throat pain and globus sensation. The symptoms occurred seven days after eating raw perch and mullet. An endoscopy under sedation showed a fluke―with an approximate length of 4.8 mm and width of 1.5 mm―on the left aryepiglottic fold, with active motility on the mucosa. It was extracted from the larynx using biopsy forceps and was identified as Clinostomum complanatum. To the best of our knowledge, this is the second reported case of human infection with Clinostomum complanatum diagnosed and treated by an endoscopy in Korea. Endoscopy is a useful tool in the diagnosis and treatment of patients at risk for parasitic infections complaining of throat pain.

BACKGROUND: Korean milk consumption and low-fat milk sales are steadily increasing. The purpose of this study was to examine the association of metabolic syndrome according to the type of milk. METHODS: The subjects included 5,553 persons who aged 19 to 64 years, from the data of the Korea National Health and Nutrition Examination Survey (KNHANES) 2013–2015. All subjects were divided by intake of type of milk that are ‘whole milk intake group’, ‘low-fat milk intake group’ and ‘no milk intake grou’p. And the subects were classified as 19-39 years old and 40-64 years old. In order to check differences of demo-sociographic characteristics and metabolic risk factors in three groups, the data was analyzed by chi-square test, t-test and binary logistic regression analysis. RESULTS: For subjects aged 40–64, whole milk intake group had lower relevance with metabolic syndrome than no milk intake group (odds ratio [OR] 0.807, P=0.035, 95% confidence interval [CI] 0.660–0.985). But low fat milk intake group was't relevant (OR 0.879, P=0.350, 95% CI 0.670–1.152). Looking at the 19-39 year-old subjects, whole milk and low fat milk intake group were not associated with metaboic syndrome (OR 1.023, P=0.911, 95% CI 0.686–1.525; OR 1.547, P=0.103, 95% CI 0.915–2.617). CONCLUSIONS: The results of this study show that whole milk intake is less relevant to the metabolic syndrome than no milk intake. Low fat milk intake was not relevant. More researches are needed to determine the effects of low fat milk and whole milk on metabolic syndrome.

BACKGROUND: Hypertension is highly prevalent among patients who visit primary care clinics. Various factors and lifestyle behaviors are associated with effective blood pressure control. We aimed to identify factors and lifestyle modifications associated with blood pressure control among patients prescribed antihypertensive agents. METHODS: This survey was conducted at 15 hospital-based family practices in Korea from July 2008 to June 2010. We prospectively recruited and retrospectively assessed 1,453 patients prescribed candesartan. An initial evaluation of patients' lifestyles was performed using individual questions. Follow-up questionnaires were administered at 4, 8, and 12 weeks. We defined successful blood pressure control as blood pressure <140 mm Hg systolic and <90 mm Hg diastolic. RESULTS: Of the 1,453 patients, 1,139 patients with available data for initial and final blood pressures were included. In the univariate analysis of the change in performance index, weight gain (odds ratio [OR], 2.18; 95% confidence interval [CI], 1.52 to 3.11; P<0.001), physical inactivity (OR, 1.195; 95% CI, 1.175 to 3.387; P=0.011), and increased salt intake (OR, 1.461; 95% CI, 1.029 to 2.075; P=0.034) were related to inadequate blood pressure control. Salt intake also showed a significant association. Multivariate ORs were calculated for age, sex, body mass index, education, income, alcohol consumption, smoking status, salt intake, comorbidity, and family history of hypertension. In the multivariate analysis, sex (OR, 3.55; 95% CI, 2.02 to 6.26; P<0.001), salt intake (OR, 0.64; 95% CI 0.43 to 0.97; P=0.034), and comorbidity (OR, 1.82; 95% CI, 1.23 to 2.69; P=0.003) were associated with successful blood pressure control. CONCLUSION: Weight gain, physical inactivity, and high salt intake were associated with inadequate blood pressure control.

Femoral nerve block with tumescent anesthesia is used to perform the radiofrequency ablation of varicose veins. The surgery can be done as day-case. But if recovery from motor block is delayed, it can make hospital discharge difficult. Prolonged femoral nerve blocks with motor blockade of the quadriceps have been noted after the use of bupivacaine. The motor blockade lasted up to 30–40 hours when 15–30 mL of 0.5% bupivacaine was used. However, it was rarely reported in ropivacaine. We report that femoral nerve block with 15 mL of 0.375% ropivacaine induced prolonged motor blockade up to 30 hours.

Glioblastoma multiforme (GBM) is the most common and aggressive form of brain tumors. GBMs, like other tumors, rely relatively less on mitochondrial oxidative phosphorylation (OXPHOS) and utilize more aerobic glycolysis, and this metabolic shift becomes augmented under hypoxia. In the present study, we investigated the physiological significance of altered glucose metabolism and hypoxic adaptation in the GBM cell line U251 and two newly established primary GBMs (GBM28 and GBM37). We found that these three GBMs exhibited differential growth rates under hypoxia compared to those under normoxia. Under normoxia, the basal expressions of HIF1α and the glycolysis-associated genes, PDK1, PDK3, and GLUT1, were relatively low in U251 and GBM28, while their basal expressions were high in GBM37. Under hypoxia, the expressions of these genes were enhanced further in all three GBMs. Treatment with dichloroacetate (DCA), an inhibitor of pyruvate dehydrogenase kinase (PDK), induced cell death in GBM28 and GBM37 maintained under normoxia, whereas DCA effects disappeared under hypoxia, suggesting that hypoxic adaptation dominated DCA effects in these GBMs. In contrast, the inhibition of HIF1α with chrysin suppressed the expression of PDK1, PDK3, and GLUT1 and markedly promoted cell death of all GBMs under both normoxia and hypoxia. Interestingly, however, GBMs treated with chrysin under hypoxia still sustained higher viability than those under normoxia, and chrysin and DCA co-treatment was unable to eliminate this hypoxia-dependent resistance. Together, these results suggest that hypoxic adaptation is critical for maintaining viability of GBMs, and targeting hypoxic adaptation can be an important treatment option for GBMs.

PURPOSE: We compared the efficacy of tamsulosin between 0.2 mg and 0.4 mg in Asian prostatic hyperplasia (BPH) patients using network meta-analysis due to lack of studies with direct comparison. METHODS: The literature search was conducted using the MEDLINE, Embase, and Cochrane Library. Keywords used were “BPH,”“tamsulosin,”“placebo.” Experimental groups were defined as tamsulosin 0.2 mg (Tam 0.2) and 0.4 mg (Tam 0.4) and common control group was defined as placebo for indirect treatment comparison. Mixed treatment comparison was performed including one direct comparison study. RESULTS: Seven studies met the eligible criteria. Indirect treatment comparison revealed that total International Prostate Symptoms Score (IPSS) and quality of life score of IPSS were not significantly different in Tam 0.2 and Tam 0.4 (P>0.05). There was no significant difference of maximal flow rate and postvoid residual urine volume in Tam 0.2 and Tam 0.4 (P>0.05). Mixed treatment comparison including one direct comparison study showed inconsistency (P<0.001). Therefore, analysis using direct treatment comparison effect sizes of Tam 0.2 vs. placebo and Tam 0.4 vs. placebo was done and there was no significant difference. CONCLUSIONS: Network meta-analysis showed no difference of efficacy between tamsulosin 0.2 mg and 0.4 mg and the evidence of tamsulosin 0.4 mg as initial dose for Asian BPH patient seems to be insufficient. Therefore, initial dose of tamsulosin for Asian BPH patient should be 0.2 mg.

Management options for patients with immune thrombocytopenia (ITP) have evolved substantially over the past decades. The American Society of Hematology published a treatment guideline for clinicians referring to the management of ITP in 2011. This evidence-based practice guideline for ITP enables the appropriate treatment of a larger proportion of patients and the maintenance of normal platelet counts. Korean authority operates a unified mandatory national health insurance system. Even though we have a uniform standard guideline enforced by insurance reimbursement, there are several unsolved issues in real practice in ITP treatment. To optimize the management of Korean ITP patients, the Korean Society of Hematology Aplastic Anemia Working Party (KSHAAWP) reviewed the consensus and the Korean data on the clinical practices of ITP therapy. Here, we report a Korean expert recommendation guide for the management of ITP.

Mucosal-associated invariant T (MAIT) cells and natural killer T (NKT) cells are known to play important roles in autoimmunity, infectious diseases and cancers. However, little is known about the roles of these invariant T cells in multiple trauma. The purposes of this study were to examine MAIT and NKT cell levels in patients with multiple trauma and to investigate potential relationships between these cell levels and clinical parameters. The study cohort was composed of 14 patients with multiple trauma and 22 non-injured healthy controls (HCs). Circulating MAIT and NKT cell levels in the peripheral blood were measured by flow cytometry. The severity of injury was categorised according to the scoring systems, such as Acute Physiology and Chronic Health Evaluation (APACHE) II score, Simplified Acute Physiology Score (SAPS) II, and Injury Severity Score (ISS). Circulating MAIT and NKT cell numbers were significantly lower in multiple trauma patients than in HCs. Linear regression analysis showed that circulating MAIT cell numbers were significantly correlated with age, APACHE II, SAPS II, ISS category, hemoglobin, and platelet count. NKT cell numbers in the peripheral blood were found to be significantly correlated with APACHE II, SAPS II, and ISS category. This study shows numerical deficiencies of circulating MAIT cells and NKT cells in multiple trauma. In addition, these invariant T cell deficiencies were found to be associated with disease severity. These findings provide important information for predicting the prognosis of multiple trauma.
