OBJECTIVE: Excessive external rotation of the hemiplegic foot is a common problem of hemiplegic gait. There has been a few report on etiological investigation and corrective measurement of an excessive external rotation of hemiplegic foot. Thus we present a newly designed Torque heel to correct the external rotation of hemiplegic foot. METHOD: Ten hemiparetic patients with an excessive external rotation of affected foot participated in this study. All of the participants were able to walk at least 10 meters with metal a ankle foot orthosis (AFO) using a single cane. Each of these patients was placed on four tries of walk: (1) on a bare foot; (2) with an AFO; (3) with an AFO and a quarter inch of lateral wedge; and (4) with an AFO and the Torque heel . Gait patterns were analysed by the Vicon 370, three dimensional motion analyser. RESULTS: The speed and stride length increased in all tries except for the bare foot walk. Those who walked with the assistive devices showed no difference in the speed and stride length. All the participants showed an increased in external rotation of pelvis and ankle. Those who walked with an AFO and Torque heel presented a decrease in the external rotation of foot and pelvis. The hip and ankle motions of the hemiplegic limbs were not affected with the AFO and Torque heel . A significant degree of correction in pelvic rotation with an AFO and Torque heel was noted. CONCLUSIONS: This study indicates that an AFO with Torque heel is beneficial to the correction of external rotation of a hemiplegic foot. And the excessive external rotation of hemiplegic foot may be due possibly to the external rotation of pelvis.

New surgical techniques utilizing computer-aided engineering have been recently developed to improve the quality of surgery and reduce the risk to patients. This paper reports the surgical cases using rapid prototyping assisted orthopeadic fracture surgery (RPAOFS). RPAOFS utilizes the symmetric characteristics of the human body, and the potential for RE and RP in which the physical shape is manufactured repidly from the CT data. The physical shape before the injury was manufactured from the RP using the mirror transformed CAD data of the uninjured extents. Subsequently, pre-operative planning, such as the selection of the proper implant, preforming of the implant, selection of the fixation positions, and surgery are performed utilizing the physical shape. RPAOFS was applied to two cases such as a distal tibia communited fracture and a proximal tibia plateau fracture. The surgical results showed that RPAOFS is an effective surgical tools.

PURPOSE: This study compared in-hospital mortality within 30 days of admission, lengths of stay, and inpatient charges among patients with heart failure admitted to public and private hospitals in South Korea. MATERIALS AND METHODS: We obtained health insurance claims data for all heart failure inpatients nationwide between November 1, 2011 and May 31, 2012. These data were then matched with hospital-level data, and multi-level regression models were examined. A total of 8406 patients from 253 hospitals, including 31 public hospitals, were analyzed. RESULTS: The in-hospital mortality rate within 30 days of admission was 0.92% greater and the mean length of stay was 1.94 days longer at public hospitals than at private hospitals (mortality: 5.18% and 4.26%, respectively; LOS: 12.08 and 10.14 days, respectively). The inpatient charges were 11.4% lower per case and 24.5% lower per day at public hospitals than at private hospitals. After adjusting for patient- and hospital-level confounders, public hospitals had a 1.62-fold higher in-hospital mortality rate, a 16.5% longer length of stay, and an 11.7% higher inpatient charge per case than private hospitals, although the charges of private hospitals were greater in univariate analysis. CONCLUSION: We recommend that government agencies and policy makers continue to monitor quality of care, lengths of stay in the hospital, and expenditures according to type of hospital ownership to improve healthcare outcomes and reduce spending.

BACKGROUND: Acute respiratory distress syndrome (ARDS) remains a life-threatening disease. Many patients with ARDS do not recover fully, and progress to terminal lung fibrosis. Angiotensin-converting enzyme (ACE) inhibitor is known to modulate the neurohormonal system to reduce inflammation and to prevent tissue fibrosis. However, the role of ACE inhibitor in the lungs is not well understood. We therefore conducted this study to elucidate the effect of renin-angiotensin system (RAS) blockage on the prognosis of patients with ARDS. METHODS: We analyzed medical records of patients who were admitted to the medical intensive care unit (ICU) at a tertiary care hospital from January 2005 to December 2010. ARDS was determined using the Berlin definition. The primary outcome was the mortality rate of ICU. Survival analysis was performed after adjustment using propensity score matching. RESULTS: A total of 182 patients were included in the study. Thirty-seven patients (20.3%) took ACE inhibitor or angiotensin receptor blocker (ARB) during ICU admission, and 145 (79.7%) did not; both groups showed similar severity scores. In the ICU, mortality was 45.9% in the RAS inhibitor group and 58.6% in the non-RAS inhibitor group (P = 0.166). The RAS inhibitor group required a longer duration of mechanical ventilation (29.5 vs. 19.5, P = 0.013) and longer ICU stay (32.1 vs. 20.2 days, P < 0.001). In survival analysis, the RAS inhibitor group showed better survival rates than the non-RAS group (P < 0.001). CONCLUSIONS: ACE inhibitor or ARB may have beneficial effect on ARDS patients.

Because additive effects of inhaled corticosteroids and long-acting anticholinergics are unclear, we undertook this study to compare the efficacy of tiotropium alone and tiotropium plus budesonide in patients with chronic obstructive pulmonary disease. The study subjects were randomized to receive either tiotropium 18 microgram once daily with or without budesonide 200 microgram twice daily for 6 weeks. The efficacy variables were changes in trough forced expiratory volume in one second (FEV1), St. George's Respiratory Questionnaire (SGRQ), 6-minute walk distance (6MWD), and use of rescue medication. One hundred patients were randomized and 81 completed the study. The mean age was 64.0 yr, and the mean FEV1 was 39.7% predicted. Compared with tiotropium alone (N=40), the tiotropium/budesonide combination (N=41) was related to an improvement in the SGRQ total score (tiotropium -2.8 units and tiotropium/budesonide -5.6 units, p=0.003). 6MWD was improved by 13.5 m in the tiotropium group and by 22.5 m in the tiotropium/budesonide group (p=0.031). Changes in trough FEV1 and the use of rescue medication were similar between two groups. In conclusion, compared with tiotropium alone, the tiotropium/ budesonide combination was related to an improved health-related quality of life. These data support that low-dose budesonide may enhance the efficacy of tiotropium.

OBJECTIVE: To identify fetal gender using fetal DNA in maternal plasma. METHODS: DNA from maternal plasma of 55 pregnant women(47: inpatients, 8: outpatients) underwent a sensitive Y-PCR assay to identify gender. RESULTS: Of the inpatients, fetus-derived Y sequences were detected in 26(80.6%) of the 31 maternal plasma samples from women bearing male fetuses. None of the 16 women bearing female fetuses had positive results from plasma DNA. Eighteen weeks is earliest gestation of gender identification. Of the outpatients(GA 8-11 weeks), fetus-derived Y sequences were detected in 7 of the 8 maternal plasma. Only one patient's fetal gender(GA 9 weeks) was identified. The others were not identified at this moment. CONCLUSION: We identified fetal DNA in maternal plasma. The sensitivity of Y-PCR was 80.6% in women bearing male fetus and the specificity was 100% in women bearing female fetus.
