We evaluated the efficacy of chotosan for headache patients via multiple regression analysis. The subjects were 46 patients with headache (31 migraine, 14 tension-type, and1combination headache), consisting of 1 3males and 33 females, mean age 48 years (range 19-77 years), who were treated with chotosan according to their Sho (symptoms) for more than1month. The relationships between the improvement of headache and 38 factors, including age, sex, height, body weight, hypertension and other symptoms noted upon first medical examination, were examined through multi-dimensional cross-sectional analysis. Morning headache, dizziness, insomnia, body weight, tinnitus and vasodilatation of sublingual veins were significant factors. Morning headache is traditionally an indication for the use of chotosan, and our results support its efficacy for this purpose. Three factors, i.e. morning headache, vasodilatation of sublingual veins and stiff shoulder, were the best subset of explanatory variables. Stiff shoulder is a key symptom for the application of chotosan, while stiffness in the back is a key symptom for the application of yokukansan.

OBJECTIVE: To study the characteristics of the diagnostic parameters of acute respiratory distress syndrome/multiple organ dysfunction syndrome on plateau (H-ARDS/MODS) and compare the accuracy of the three MODS scoring criteria in predicting the outcome of syndrome. METHODS: Five hundred and forty cases fulfilling the criteria of MODS were divided into four groups according to the altitude of their inhabitation area: control group (on plain, CG, n=113, altitude: <430 m), moderate high altitude group 1 (H1G, n=314, altitude: 1,517 m), moderate high altitude group 2 (H2G, n=78, altitude: 2,261 m to 2,400 m) and high altitude group (HG, n=35, altitude: 2 808 m to 3 400 m). According to the diagnostic criteria of Lushan conference and Marshall (1995) commonly used on plain, and Lanzhou criteria drafted by the authors, three data analyzing models were set up to draw the receiver operating characteristic (ROC) curves, the Yordon Index and the optimum cutoff points of the parameters were calculated and the accuracy of the three respective diagnostic criteria was evaluated in predicting the outcome of ARDS/MODS. Multiple factors affecting the outcome of MODS were analyzed using the method of stepwise forward regress model. RESULTS: Following the increase in altitude, Lanzhou criteria was clearly superior to the other two criteria in the area of ROC, the sensitivity, the specificity, and also for the optimum cutoff points of MODS. Multi-variable regression analysis showed that the impacting factor of Lanzhou criteria was the highest (P<0.05). CONCLUSION: (1)Some parameters of the current diagnostic criteria of ARDS/MODS are not suitable in moderately high or high altitude areas. It is necessary to set up the diagnostic criteria of H-ARDS/MODS. (2)Some clinical characteristics might change in areas 1,500 m altitude or higher. The pathophysiological mechanism might be attributable to peculiar biologic reactions due to hypoxia stress reaction, and it is worth further study.

BACKGROUND: Angiogenesis and osteoclastogenesis are increased in the bone marrow of multiple myeloma (MM) patients in parallel with the tumor progression. Osteopontin (OPN) is a multifunctional protein that is involved in angiogenesis and bone destruction and, eventually, in tumor progression in MM. OPN is known to increase in MM patients as the disease progresses and bone is destroyed. We studied the clinical usefulness of OPN as a monitoring marker for treatment response in patients with MM. METHODS: We obtained 70 serial sera from 27 MM patients and 14 sera from healthy individuals. OPN was measured by a sandwich ELISA method. The hospital records were reviewed, and the clinically important markers for monitoring the treatment response, such as monoclonal component, immunoglobulin, free light chain, and hemoglobin, etc, were analyzed together with OPN levels. RESULTS: There was no significant difference in OPN levels between MM patients and healthy controls. OPN showed no significant correlations with the markers used for monitoring of treatment response such as M component, immunoglobulin, and free light chain levels. There was no difference in OPN levels between the 3 groups classified by the amount of M component. In addition, OPN levels showed no compatible changes to the treatment response of MM patients. CONCLUSIONS: Although OPN has been known to have an important role in the formation and progression of MM by involving angiogenesis and bone destruction, our results show that OPN is not valuable as a clinical marker for monitoring the treatment response in MM patients because of inconsistency in its levels in MM patients.

The goal of this study was to evaluate the prevalence of first-line anti-tuberculosis drug resistance and risk factors associated with multidrug-resistant tuberculosis (MDR TB) among young soldiers in the Korean military, which has a strict tuberculosis control program. All patients with culture-confirmed pulmonary tuberculosis during their service at the Armed Forces Capital Hospital from January 2001 to December 2006 were enrolled in the study. Drug resistant Mycobacterium tuberculosis was isolated from 18 patients (12.2%) and multidrug-resistant M. tuberculosis was isolated from 12 patients (8.1%). Previous treatment of tuberculosis and the presence of a cavity on the patient's chest computed tomography scan were associated with MDR TB; military rank, smoking habits, and positive acid-fast bacilli smears were not associated with MDR TB. In a multiple logistic regression analysis, previous treatment of tuberculosis was a significant independent risk factor for MDR TB (odds ratio 6.12, 95% confidence interval 1.53-24.46). The prevalence of drug resistant tuberculosis among young soldiers in the Korean military was moderately high and the majority of resistant cases were found in patients who had undergone previous treatment of tuberculosis. Based on our results, we suggest that relapsed tuberculosis cases within communal settings should be cautiously managed until the drug susceptibility tests report is completed, even if previous treatment results were satisfactory.

BACKGROUND: Bone mass changes in men is related to age, BMI, sex hormones and other factors. In prior studies, bone markers were negatively correlated with bone mineral density, free testosterone, and estrogen and was positively correlated with SHBG. In a study of sex hormones and bone markers in Korean men estradiol was negatively correlated with deoxypyridinoline. In this study, the relationship of testosterone, estradiol, calculated free testosterone, FEI and SHBG to bone turnover markers in adult men were investigated. METHODS: This was a cross-sectional study of 184 men who had undertaken a health screening program in one general hospital in Bundang from November, 2001 to February, 2003. We surveyed information concerning the past medical history, current medication, alcohol consumption amount per week and smoking amount by means of self questionnaire records. Serum total testosterone, estradiol, SHBG and osteocalcin, alkaline phosphatase were measured at a fasting state. Urine was tested for deoxypyridinoline. Free testosterone was calculated using albumin, SHBG, and total testosterone level. RESULTS: Deoxypyridinoline adjusted by age, BMI was negatively correlated with FEI (r=-0.17, P=0.020) and was positively correlated with smoking amount (r=0.20 P= 0.007). Osteocalcin was negatively correlated with calculated free testosterone and ethanol consumption amount (r=-0.186, P=.0.12, r=-0.186, P=0.012). Multiple regression analysis showed that the most powerful factor influencing deoxypyridinoline was smoking amount (R2= 0.046), followed by FEI, BMI, and the one influencing osteocalcin was BMI (R2=0.050), ethanol amount and calculated free testosterone. After adjusting for age, BMI, drinking amount and smoking amount FEI shown to be a predictor of deoxypyridinoline (beta=-0.08, p<0.01, R2=0.101). After adjusting for age, BMI, and drinking amount calculated free testosterone was shown to be a predictor of osteocalcin (beta=-0.570, P<0.01, R2=0.130) in multiple regression model. CONCLUSIONS: In adult men, FEI shown to be a predictor of deoxypyridinoline and calculated free testosterone to be a predictor of osteocalcin as an independent variable.

BACKGROUND: Angiogenesis is important for the proliferation and survival of multiple myeloma (MM) cells. Bone marrow (BM) microvessel density (MVD) is a useful marker of angiogenesis and is determined by immunohistochemical staining with anti-CD34 antibody. This study investigated the prognostic impact of MVD and demonstrated the relationship between MVD and previously mentioned prognostic factors in patients with MM. METHODS: The study included 107 patients with MM. MVD was assessed at initial diagnosis in a blinded manner by two hematopathologists who examined three CD34-positive hot spots per patient and counted the number of vessels in BM samples. Patients were divided into three groups according to MVD tertiles. Cumulative progression-free survival (PFS) and overall survival (OS) curves, calculated by using Kaplan-Meier method, were compared among the three groups. Prognostic impact of MVD was assessed by calculating Cox proportional hazard ratio (HR). RESULTS: Median MVDs in the three groups were 16.8, 33.9, and 54.7. MVDs were correlated with other prognostic factors, including beta2-microglobulin concentration, plasma cell percentage in the BM, and cancer stage according to the International Staging System. Multivariate Cox regression analysis showed that high MVD was an independent predictor of PFS (HR=2.57; 95% confidence interval, 1.22-5.42; P=0.013). PFS was significantly lower in the high MVD group than in the low MVD group (P=0.025). However, no difference was observed in the OS (P=0.428). CONCLUSIONS: Increased BM MVD is a marker of poor prognosis in patients newly diagnosed with MM. BM MVD should be assessed at the initial diagnosis of MM.
