Defective T wave combined with incomplete right bundle branch block: a new electrocardiographic index for diagnosing atrial septal defect / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Incomplete right bundle branch block (ICRBBB) is commonly associated with atrial septal defect (ASD), but lacks sufficient diagnostic test characteristics. An abnormal T wave is also often observed in ASD, with horizontal or inverted displacement of the proximal T wave limb in the right precordial leads, termed "defective T wave" (DTW).</p><p><b>METHODS</b>We examined the diagnostic test characteristics of combining ICRBBB with DTW as a new index to diagnose ASD. A total of 132 consecutive patients with ASD and 132 cases of age/gender-matched controls without ASD were enrolled.</p><p><b>RESULTS</b>Sensitivities of DTW, ICRBBB, and both were 87.1% - 87.9%. Specificities were 97.0%, 96.2%, and 100%, respectively. Positive predictive values were 1.3%, 1.1%, and 100.0% respectively, while negative predictive values were 99.9% for each.</p><p><b>CONCLUSION</b>Combining ICRBBB with DTW in electrocardiogram (ECG) as a new index significantly increased the specificity and positive predictive values while maintaining a high sensitivity in diagnosing ASD.</p>

Literature review of the efficacy and safety of hyperthermic intraperitoneal perfusion chemotherapy after cytoreductive surgery in the treatment of pseudomyxoma peritonei / 中华胃肠外科杂志

<p><b>OBJECTIVE</b>To evaluated the safety and efficacy of hyperthermic intraperitoneal perfusion chemotherapy(HIPC) in the prevention and treatment of pseudomyxoma peritonei (PMP) recurrence after cytoreductive surgery(CRS).</p><p><b>METHODS</b>Studies published in English before 2010 on HIPC after CRS for PMP were searched in PubMed database. Each study was carefully evaluated based on pre-determined criteria. Study results were comprehensively displayed in a form. A descriptive systematic review was performed.</p><p><b>RESULTS</b>A total of 11 studies were included. The median survival time of patients in these studies ranged from 25.6 months to 156 months. The ranges of 1-year, 2-year, 3-year, 5-year, and 10-year survival rates were 72%-100%, 55%-96%, 59%-96%, 52%-96%, and 55%-96%, respectively. The overall complication rate ranged from 2%-15%, and the total perioperative mortality were from 0 to 7%.</p><p><b>CONCLUSION</b>HIPC after CRS is effective and safe for patients with PMP.</p>
