PURPOSE: We evaluated the effect of tamsulosin for the short-term treatment of urinary stones. MATERIALS AND METHODS: Two hundred forty-seven patients who were diagnosed with urinary stones were enrolled in this prospective, randomized multicenter study. The treatment and extracorporeal shock wave lithotripsy (ESWL) group (Group 1, n=115) was given diclofenac sodium 100 mg plus tamsulosin 0.2 mg for 1 week. The control and SWL group (Group 2, n=92) was given diclofenac sodium for 1 week. The treatment and no SWL group (Group 3, n=19) was treated the same as Group 1. The control and no SWL group (Group 4, n=21) was given diclofenac sodium only. Patients in Groups 3 and 4 did not want to take SWL treatment. The size of the stone, expulsion rate according to stone location and ESWL machines, changes in pain score, and distance of stone migration when expulsion of the stone failed were compared among the groups. RESULTS: There were no differences in the 4 groups in sex or stone size. The stone expulsion rate of lower ureter stones in group 1 (59.6%) was significantly higher than in group 2 (30.8%) (p=0.01). The distance of stone migration in group 3 was longer than that in group 4 (5.63+/-5.48 cm compared with 0.33+/-0.68 cm; p=0.002). Although the difference was not significant in the SWL groups, the distance of stone migration in group 1 was longer than that in group 2 (7.08+/-6.9 cm compared with 5.46+/-7.4 cm; p>0.05). There were no significant differences in changes on the pain scale among the groups. CONCLUSIONS: These results suggest that adjunctive medical therapy for 1 week with tamsulosin after SWL increases the stone expulsion rate of lower ureteral stones and increases the distance of stone migration in case of failure of stone expulsion.

The present study was conducted to determine the antibiotic susceptibilities of local Mycoplasma hyopneumoniae (Mhp) and Mycoplasma hyorhinis (Mhr) filed isolates. Minimum inhibitory concentrations (MICs) of Mhp and Mhr field isolates (twelve each) obtained from enzootic pneumonia-like lung lesions during 2009-2011 from Korea were determined using the broth microdilution method. Tylvalosin showed the highest activity against Mhp and Mhr field isolates, with MIC90 values of 0.06 µg/mL and 0.12 µg/mL, respectively. Therefore, Korean Mhp and Mhr isolates are highly susceptible to tylvalosin.

In addition to cellular damage, ischemia-reperfusion (IR) injury induces substantial damage to the mitochondria and endoplasmic reticulum. In this study, we sought to determine whether impaired mitochondrial function owing to IR could be restored by transplanting mitochondria into the heart under ex vivo IR states. Additionally, we aimed to provide preliminary results to inform therapeutic options for ischemic heart disease (IHD). Healthy mitochondria isolated from autologous gluteus maximus muscle were transplanted into the hearts of Sprague–Dawley rats damaged by IR using the Langendorff system, and the heart rate and oxygen consumption capacity of the mitochondria were measured to confirm whether heart function was restored. In addition, relative expression levels were measured to identify the genes related to IR injury. Mitochondrial oxygen consumption capacity was found to be lower in the IR group than in the group that underwent mitochondrial transplantation after IR injury (p < 0.05), and the control group showed a tendency toward increased oxygen consumption capacity compared with the IR group. Among the genes related to fatty acid metabolism, Cpt1b (p < 0.05) and Fads1 (p < 0.01) showed significant expression in the following order: IR group, IR + transplantation group, and control group. These results suggest that mitochondrial transplantation protects the heart from IR damage and may be feasible as a therapeutic option for IHD.

BACKGROUND AND PURPOSE: It was recently reported that the prevalence of poststroke memory dysfunction might be higher than previously thought. Stroke may exist concomitantly with underlying Alzheimer's disease (AD), and so we determined whether post-stroke memory dysfunction indicates manifestation of underlying subclinical AD. METHODS: Of 1201 patients in a prospective cognitive assessment database, we enrolled subjects with poststroke amnestic vascular cognitive impairment-no dementia (aVCIND; n=48), poststroke nonamnestic vascular cognitive impairment-no dementia (naVCIND; n=50), and nonstroke amnestic mild cognitive impairment (aMCI; n=65). All subjects had cognitive deficits, but did not meet the criteria for dementia. A standardized neuropsychological test battery and magnetic resonance imaging were performed at least 90 days after the index stroke (mean, 473 days). Visual assessment of medial temporal atrophy (MTA) was used as a measure of underlying AD pathology. RESULTS: The MTA score was significantly lower in the naVCIND group (0.64+/-0.85, mean+/-SD) than in the aVCIND (1.10+/-1.08) and aMCI (1.45+/-1.13; p<0.01) groups. Multivariable ordinal logistic regression analysis revealed that compared with naVCIND, aVCIND [odds ratio (OR)=2.69; 95% confidence interval (CI)=1.21-5.99] and aMCI (OR=5.20; 95% CI=2.41-11.23) were significantly associated with increasing severity of MTA. CONCLUSIONS: Our findings show that compared with poststroke naVCIND, the odds of having more-severe MTA were increased for poststroke aVCIND and nonstroke aMCI.

BACKGROUND AND PURPOSE: A substantial proportion of patients with atrial fibrillation (AF) are not treated optimally; however, the inappropriateness of drug therapy has never been evaluated before or after a stroke event. We investigated the adherence to guidelines for therapy in AF patients hospitalized with acute ischemic stroke (AIS) before stroke onset and at discharge, with the aim of identifying the factors associated with inappropriate therapy. METHODS: AIS patients with AF hospitalized within 7 days of onset were identified from a prospective nine-center stroke registry database. Two cohorts were defined: patients diagnosed with AF prior to the stroke event (admission cohort) and patients diagnosed with AF at discharge from hospital (discharge cohort). Any of the following conditions were regarded as nonadherence to guidelines in this study: use of anticoagulant or nonuse of antithrombotics with CHADS2 score=0, nonuse of antithrombotics with CHADS2 score=1, or nonuse of anticoagulant with CHADS2 score > or =2. RESULTS: Overall, 406 patients were enrolled in the admission cohort and 518 in the discharge cohort. The rates of nonadherence before a stroke event and at discharge were 77.8% and 33.3%, respectively. These rates varied widely for both cohorts, with interhospital differences being statistically significant. Multivariable analysis revealed that old age, stroke history, and congestive heart failure were associated with nonadherence before stroke. At discharge, males, coronary heart disease, inappropriate antithrombotic use before stroke, and functional disability at discharge were associated with nonadherence. CONCLUSIONS: This study shows that antithrombotic use in AIS patients with AF might be not optimal before and after stroke in Korea.
