Background: Rhabdomyolysis is a potentially life-threatening syndrome that can develop from a variety of causes. The aim of the work is to analyze the clinical spectrum and to evaluate the prevalence of various etiologies in children, who present to the emergency department (ED) with rhabdomyolysis. Methods: During a 6-year study period, we retrospectively analyzed the medical charts of patients, aged 18 years or younger, with a definite diagnosis of rhabdomyolysis and serum creatinine phosphokinase (CK) levels greater than 1000IU/L. We analyzed the clinical spectrum and evaluated the potential risk factors of acute renal failure (ARF). Results: Thirty-seven patients (mean age = 10.2 +/- 5.5 years), including 26 males and 11 females, were enrolled in the study. Two of the most common presented symptoms in these 37 patients were muscle pain and muscle weakness (83.8% and 73%, respectively). Dark urine was reported in only 5.4% of the patients. The leading cause of rhabdomyolysis in the 0- to 9-year age group was presumed infection, and the leading cause in the 10- to 18-year age group was trauma and exercise. The incidence of ARF associated with rhabdomyolysis was 8.1 % and no child needed for renal replacement therapy (RRT). We did not identify any reliable predictors of ARF or need for RRT. Conclusions: The classic triad of symptoms of rhabdomyolysis includes myalgia, weakness and dark urine are not always presented in children. The cause of rhabdomyolysis in younger age is different from that of teenager group. However, the prognosis of rhabdomyolysis was good with appropriate management.

Purpose: This study aimed to determine whether routine urinalysis may serve as a tool in discriminating between acute appendicitis and perforated appendicitis in children. Basic procedures: We prospectively collected 357 patients with clinically suspected acute appendicitis. Urinalysis was performed in patients with clinically suspected acute appendicitis before surgical intervention. Routine urinalysis is composed of 2 examinations: chemical tests for abnormal chemical constituents and microscopic tests for abnormal insoluble constituents. Receiver operating characteristic curves for urine white blood cell (WBC) counts and urine red blood cell (RBC) counts in distinguishing between patients with simple appendicitis and patients with perforated appendicitis were also analyzed. Main findings: Urine ketone bodies, leukocyte esterase, specific gravity, pH, WBC, and RBC counts were all significant parameters among patients with normal appendices, simple appendicitis, and perforated appendicitis (all P < .05). Based on multivariate logistic regression analysis, positive urine ketone bodies and nitrate were significant parameters in predicting perforated appendicitis (P = .002 and P = .008, respectively). According to the results of receiver operating characteristic curves, the appropriate cutoff values were 2.0/high-power field for urine RBC counts and 4.0/high-power field for urine WBC counts in predicting perforated appendicitis in children. Principal conclusions: Routine urinalysis may serve to aid in discriminating between simple and perforated appendicitis. Clinically, we believe that these urine parameters may aid primary emergency physicians with decision making in patients with clinically suspected appendicitis. (C) 2013 Elsevier Inc.

This study aimed to determine predictive factors for sustained return of spontaneous circulation (ROSC) in pediatric patients with traumatic out-of-hospital cardiac arrest (OHCA) and compared to those with nontraumatic OHCA. This was a retrospective prognostic study of children with OHCA presenting to the emergency department (ED) was conducted from 2005 to 2010. Related clinical factors that influenced sustained ROSC in traumatic OHCA patients were identified and compared to nontraumatic cases. Significant parameters in predicting sustained ROSC in traumatic OHCA children were also determined using multivariate logistic regression analysis, and etiologies of the ICU admissions were analyzed in patients with sustained ROSC. Among 2,978 critically ill children admitted to the ED, 150 were pediatric OHCA patients, including 76 traumatic cases and 74 nontraumatic cases. Of children with OHCA, initial sustained ROSC was achieved in 51 cases (34.0 %), including 31 traumatic cases and 20 of nontraumatic cases. Head and neck injuries were the majority of traumatic cases in the traumatic OHCA children, followed by abdominal injuries and chest injuries. However, abdominal injuries accounted for the highest rate to gain sustained ROSC, while chest injuries had the lowest rate for successful sustained ROSC. Significant factors associated with sustained ROSC in traumatic OHCA included initial cardiac rhythm (P < 0.05), the period from scene to hospital (P < 0.05), and the duration of in-hospital cardiopulmonary resuscitation (CPR) (P < 0.05). Significant factors related to sustained ROSC have been identified as initial cardiac rhythm, duration of in-hospital CPR, and the period from scene to hospital. Head and neck injuries were the majority of traumatic cases and the prevention in head and neck trauma may play an important part in public health aspects.
