ABSTRACT
<p><b>OBJECTIVE</b>To study the value of transesophageal atrial pacing (TEAP) in neonates with tachyarrhythmia.</p><p><b>METHODS</b>The clinical data of 26 neonates with tachyarrhythmia who underwent TEAP electrophysiological examination or cardioversion were collected.</p><p><b>RESULTS</b>Of the 26 neonates, 15(58%) were diagnosed with atrioventricular reentrant tachycardia, 3(12%) were diagnosed with sinus tachycardia, 3(12%) were diagnosed with ventricular tachycardia, 2(8%) were diagnosed with fast/slow atrioventricular nodal reentrant tachycardia, 2(8%) were diagnosed with atrial tachycardia, and 1(4%) was diagnosed with sinus tachycardia with ventricular preexcitation. Overdrive suppression was performed for 22 neonates, among whom 18 achieved successful cardioversion, and 2 with atrial tachycardia and 2 with ventricular tachycardia failed to restore sinus rhythm.</p><p><b>CONCLUSIONS</b>TEAP is helpful to the diagnosis of tachyarrhythmia in neonates and can bring about a high rate of cardioversion success.</p>
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the causes of unintentional injuries in children and to provide reference for reducing the incidence of unintentional injuries in children.</p><p><b>METHODS</b>A retrospective analysis was performed on the clinical data of 924 children with unintentional injuries who were hospitalized in Zhongshan Boai Hospital from January 2008 to December 2010.</p><p><b>RESULTS</b>Of the 924 cases, 26.4% suffered falls, which was the most common cause of injuries, 15.7% suffered burns and scalds, 14.0% were injured by foreign bodies, and 13.1% were injured in traffic accidents. Unintentional injuries occurred mainly among children aged 0-3 years (67%). The proportion of cases in summer (July to September) was significantly higher than in any other season (P < 0.05), and burns were the common causes of injuries in summer. Home was the most common place where unintentional injuries occurred (36.9%). The incidence of traffic accidents was significantly higher in non-local children than in local children (P < 0.001). As for the parents' educational levels, the children whose parents had an education level below junior middle school accounted for the highest proportion of all cases of unintentional injury (45.5%). Injuried cases in rural areas accounted for a significantly higher percentage than in urban areas (P < 0.05).</p><p><b>CONCLUSIONS</b>Falls are the principal cause of unintentional injuries in children. Young children (0-3 years) are most vulnerable to unintentional injuries. Unintentional injuries mostly occur at home. The incidence of traffic accidents is higher in non-local children than in local children. Parents' education levels are associated with the incidence of unintentional injuries. In order to reduce the incidence of unintentional injuries in children, preventive measures must be carried out, and safety education should be enhanced in consideration of children's age, sex and family background.</p>

<p><b>OBJECTIVE</b>To explore the clinical value of urodynamic study in patients with neurogenic bladder by pelvic fracture postoperative.</p><p><b>METHODS</b>Postoperative 12 cases with pelvic fracture resulted in uroschesis, there were 8 males and 4 females,and age from 26 to 70 years with an average of 46.5 years. Urodynamic study was done in patients at 1 d,1,3 weeks after operation and compared with 12 cases normal subjects.</p><p><b>RESULTS</b>There was a significant relationship between urodynamic parameter (including residual urine volume of bladder, max free flow, urethral closing pressure in filling end and so on) and course of disease. The residual urine volume of bladder and urethral closing pressure in filling end increased of urodynamic tests in all patients with uroschesis as compared with the normal subjects (P < 0.05); but max free flow decreased at 1 d, 1, 3 weeks after operation (P < 0.05). In the patients with uroschesis, residual urine volume of bladder markedly increased (P < 0.05) and urethral closing pressure in filling end markedly depressed (P < 0.05) at 1 week after operation than other time (at 1 d, 3 weeks after operation), but max free flow had not significant difference (P > 0.05).</p><p><b>CONCLUSION</b>Urodynamic study might evaluate regenerate the degree of neurogenic bladder by pelvic fracture postoperative and predict the prognosis of the neurogenic bladder.</p>
