PURPOSE: This study was to compare short arm double splint allowing forearm rotation with sugar tong splint in terms of loss of reduction and incidence of shoulder stiffness after closed reduction of the distal radius factures. METHODS: From June 2012 to February 2013, we retrospectively reviewed patients with distal radius fractures applied short arm double splint or sugar tong splint after closed reduction. Patients with more than 18 years old, acceptable reduction in X-ray and followed up at least 4 weeks were enrolled. Short arm double splint (SD) group was applied in 47 cases and sugar tong splint (ST) group was 34 cases. Gender, age and fracture types were not significantly different between two groups. The radiographic parameters were measured for palmar tilt, articular step-off, radial length, radial inclination, ulnar variance. The incidence and time of the reduction loss were also evaluated. In functional outcomes, the occurence of ipsilateral shoulder stiffness and the disabilities of the arm, shoulder and hand (DASH) score were evaluated with the medical records or telephone questionnaires at 6 months after initial trauma. RESULTS: Loss of reduction was occured 16 cases in SD group (34%) and 10 cases in ST group (29.4%), which did not differ significantly between the groups (p=0.169). The DASH score and shoulder stiffness were not statistically different between two groups. CONCLUSION: There was no significant difference in loss of reduction after closed reduction of distal radius fractures and functional outcomes in both groups.

BACKGROUND/AIMS: Serum procalcitonin (PCT) levels are low in healthy individuals but are elevated in patients with a serious bacterial infection or sepsis. In this study, we examined the ability of serum PCT concentration to diagnose infections in end-stage renal disease (ESRD) patients, and sought to determine an appropriate threshold level. METHODS: Serum PCT levels were measured in ESRD patients on antibiotic therapy for a suspected bacterial infection (ESRD infection [iESRD] group, n = 21), and compared with those of ESRD patients on hemodialysis with no sign of infection (ESRD control [cESRD] group, n = 20). RESULTS: The mean serum PCT concentration of the iESRD group was significantly higher than in the cESRD group (2.95 +/- 3.67 ng/mL vs. 0.50 +/- 0.49 ng/mL, p = 0.006), but serum PCT concentrations did not correlate with severity of infection. The optimized threshold level derived for serum PCT was 0.75 ng/mL, rather than the currently used 0.5 ng/mL; this threshold demonstrated a sensitivity and specificity of 76.2% and 80.0% for infection and 100% and 60.6% for systemic inflammatory response syndrome, respectively, compared with the cutoff of 0.5 ng/mL. CONCLUSIONS: This study suggests that serum PCT at a cutoff value of 0.75 ng/mL is an appropriate indicator of infection in ESRD patients.

PURPOSE: It has been studied prognostic factors about secondary displacement after conservative treatment of the distal radius fracture, but each study showed different results. Authors retrospectively evaluated factors known to be involved secondary displacement of the distal radius fracture to determine its significance. METHODS: One hundred eighteen cases of the radiographically unstable distal radius fractures that closed reduction was adequately performed were retrospectively studied and the radiographic images were taken at 1, 2, 3, 4, 6 weeks after closed reduction. During follow-up, dorsal tilt more than 15°, volar tilt more than 20°, ulnar positive variance more than 4 mm, radial length less than 6 mm, radial inclination less than 10° were thought of the loss of reduction. RESULTS: In 41 cases (34.7%), the loss of reduction occurred. Sex, intra-articular fracture, dorsal and volar comminution, concomitant ulnar fracture and involvement of the distal radio-ulnar joint were statistically not significant. Analysis results of the binomial logistic regression model were as follows: age (p=0.003), radial shortening (p=0.010) and ulnar positive variance (p=0.010) were statistically significant as the predictive prognostic factors. Analysis results of the multinomial logistic regression model showed age (p=0.006) as an only statistically significant factor. CONCLUSION: As the predictive prognostic factors for development of secondary displacement after conservative treatment of the unstable distal radius fracture, age was determined as most significant factor. Also radial shortening and ulnar positive variance were thought of the predictive factors for secondary displacement.

PURPOSE: To present preliminary results of intensity-modulated radiotherapy (IMRT) using the simultaneous modulated accelerated radiation therapy (SMART) boost technique in patients with nasopharyngeal carcinoma (NPC). MATERIALS AND METHODS: Twenty patients who underwent IMRT for non-metastatic NPC at the Asan Medical Center between September 2001 and December 2003 were prospectively evaluated. IMRT was delivered using the "step and shoot" SMART technique at prescribed doses of 72 Gy (2.4 Gy/day) to the gross tumor volume (GTV), 60 Gy (2 Gy/day) to the clinical target volume (CTV) and metastatic nodal station, and 46 Gy (2 Gy/day) to the clinically negative neck region. Eighteen patients also received concurrent chemotherapy using cisplatin once per week. RESULTS: The median follow-up period was 27 months. Nineteen patients completed the treatment without interruption; the remaining patient interrupted treatment for 2 weeks owing to severe pharyngitis and malnutrition. Five patients (25%) had RTOG grade 3 mucositis, whereas nine (45%) had grade 3 pharyngitis. Seven patients (35%) lost more than 10% of their pretreatment weight, whereas 11 (55%) required intravenous fluids and/or tube feeding. There was no grade 3 or 4 chronic xerostomia. All patients showed complete response. Two patients had distant metastases and loco-regional recurrence, respectively. CONCLUSION: IMRT using the SMART boost technique allows parotid sparing, as shown clinically and by dosimetry, and may also be more effective biologically. A larger population of patients and a longer follow-up period are needed to evaluate ultimate tumor control and late toxicity.
