Comparison of success and pain levels of supination-flexion and hyperpronation maneuvers in childhood nursemaid's elbow cases.

OBJECTIVE: The aim of this study was to compare the hyperpronation (HP) and the supination-flexion (SF) reduction techniques for reducing nursemaid's elbow in terms of efficacy and pain. METHODS: This prospective, pseudorandomized, controlled, nonblinded study was conducted in an urban tertiary care emergency department between October 1, 2009, and October 1, 2010. A total of 150 patients (51 males [34%] and 99 females [66%] between the ages of 0 to 6 years) were included in the study. When the first reduction attempt failed, second attempt was performed using the same technique. After failure of the second attempt, reduction technique was changed to an alternate technique. Level of pain was evaluated using the Modified Children's Hospital of Eastern Ontario Pain Scale in 113 patients older than 1 year who had a successful reduction process on the first attempt. RESULTS: Successful reduction was accomplished in 121 (80.7%) of the patients during the first attempt, in 56 (68.3%) of the patients using the SF technique and in 65 (95.6%) of the patients using the HP technique (P < .001). At the end of total attempts, we found that the SF (59/84) technique was less successful than the HP (91/93) technique (P < .001). The pain levels of the both techniques were not statistically different. CONCLUSION: The HP technique was found to be more successful compared with the SF technique in achieving reduction. We were unable to find any significant difference in pain levels observed between the 2 techniques.

Elevated serum S100B protein and neuron-specific enolase levels in carbon monoxide poisoning.

OBJECTIVE: Carbon monoxide (CO) poisoning causes cerebral and generalized hypoxia. This study aimed to assess the possible use of serum glial marker S100B protein and neuron-specific enolase (NSE) as biochemical markers of hypoxic brain damage in acute CO poisoning. METHODS: Patients with acute CO poisoning admitted to the ED of 2 training hospitals (Ankara, Turkey) were included in this cross-sectional study. Serum levels of S100B and NSE were measured on admission. The patients were divided into 2 groups (unconscious and conscious). Twenty healthy adults were included in the study to serve as controls. RESULTS: A total of 70 patients poisoned by CO (mean age +/- SD, 36.6 +/- 16.3 years; 64.3% women) were enrolled. Although S100B concentrations were higher in patients than in the control group (P = .018), no significant difference was determined between patient and control groups with respect to NSE concentrations (P = .801). A positive correlation was noted between levels of S100B and NSE (r = 0.388; P = .001). The S100B and NSE values were higher in unconscious patients than in the control group (P = .002 and P = .013, respectively). Furthermore, S100B and NSE values were higher in unconscious vs unconscious patients (P = .047 and P = .005, respectively). CONCLUSION: Elevated serum S100B and NSE levels were associated with loss of consciousness in CO poisoning in this series of patients. Serum S100B and NSE may be useful markers in the assessment of clinical status in CO poisoning.
