BACKGROUND: This study evaluated the performance of 2 Bayer Hepatitis B Chemiluminescent Assays by comparing their performance to the corresponding DPC Immulite 2000 assays. METHODS: 953 samples were tested by both Immulite 2000 and Centaur HBsAg methods; and 75 samples were tested by both Immulite 2000 and Centaur anti-HBc IgM methods. RESULTS: The overall agreement between Immulite 2000 and ADVIA Centaur anti-HBc IgM assays was 100%. The agreement between Immulite 2000 and Centaur HBsAg assays was 100% for Immulite 2000 positive samples. The overall agreement for HBsAg negative samples was 99.9% after confirmation result was included. However, discrepancy between the 2 assays was observed in 53 samples which were tested initially as "weakly reactive"(index 1.0-1.95) but were not confirmed subsequently by the neutralization test on Immulite 2000. All 53 samples tested negative by Centaur HBsAg assay at the initial run. Furthermore, one Immulite 2000 HBsAg negative sample was reactive and confirmed by Centaur assay. CONCLUSIONS: While the performance of Bayer Hepatitis B HBsAg and aHBc IgM assays are in good agreement with corresponding DPC assays, the Bayer HBsAg assay is more efficient than the Immulite 2000 assay with its better separation of signal and background noise, and its complete automation features. 相似文献

Background
Total parenteral nutrition (TPN) is often used in children with perforated appendicitis, despite the absence of clear indications. We assessed the validity of specific clinical indications for initiation of TPN in this patient cohort.Methods
Data were gathered prospectively on duration of nil per os (NPO) status and TPN use in a cohort of children treated under a perforated appendicitis protocol during a 19-month period. TPN was started in the immediate postoperative period in patients who had generalized peritonitis and severe intestinal dilatation at operation, or later per the discretion of the attending surgeon. At discharge, TPN was considered to have been used appropriately, according to consensus guidelines, if the patient was NPO ≥ 7 days or received TPN ≥ 5 days.Results
During the study period, TPN was initiated in 31 (25.4%) of 122 patients operated for perforated appendicitis. Sixteen (51.6%) received TPN per operative finding indications and 15 (48.4%) for prolonged ileus. The operative indications demonstrated 47% sensitivity, 86% specificity, a positive predictive value (PPV) of 35%, and a negative predictive value (NPV) of 91%, when adherence to TPN consensus guidelines was considered the gold standard.Conclusion
Patients without severe intestinal dilatation and generalized peritonitis at operation should not be placed on TPN in the immediate postoperative period. Refinement of selection criteria is necessary to further decrease inappropriate TPN use in children with perforated appendicitis.Type of study

Background
Tracheomalacia is the most common congenital abnormality of the trachea. Posterior tracheopexy to alleviate posterior intrusion contributing to dynamic tracheal collapse has been reported using thoracotomy or median sternotomy. Here we describe the minimally invasive operative technique of thoracoscopic posterior tracheopexy with bronchoscopic guidance.Operative technique
After preoperative computed tomography and bronchoscopy, a right thoracoscopic approach is utilized. The esophagus is mobilized and the membranous trachea is sutured to the prevertebral fascia under direct bronchoscopic visualization. Immediate improvement in tracheal collapse is noted. No major complications are reported and length of stay is short. Aortopexy may also be required to address anterior vascular compression.Conclusion
Thoracoscopic posterior tracheopexy is safe and feasible. Further studies with more patients and longer follow-up are needed to assess durability. 相似文献106.
