This study is to investigate the predictive factors of blood loss in ankylosing spondylitis (AS) patients. Retrospective analysis was performed in patients with thoracolumbar kyphotic deformity secondary to ankylosing spondylitis who underwent PSO from 2008 through 2013. Patient's demographics, preoperative and postsurgical global kyphosis (GK) angle, preoperative hematologic tests and other factors related to PSO were analyzed. ⋯ Multiple stepwise analysis identified male sex (P = 0.000), and two-level osteotomy (P = 0.016) to be predictive factors of increased EBL/EBV percentage in AS patients undergoing PSO for thoracolumbar kyphosis. Male and two-level osteotomy are the two most significant factors predicting increased EBL/EBV percentage in AS patients undergoing PSO for thoracolumbar kyphosis. These predictors can provide more adequate preoperative preparations.

Wire-reinforced endotracheal tubes are used to prevent obstruction. Risk factors related to reinforced endotracheal tube obstruction were believed to be repeatedly used tube and in presence of N2O. In our case, even in free of these risk factors, a delayed tube obstruction occurred with the progress of surgical duration. This delay suggests that the obstruction was caused by diffusion of warm air/oxygen into an initially small defect, especially as the duration of surgery progresses.

Giant congenital melanocytic nevi (GCMN) are rare conditions that defined as melanocytic lesion recognized at birth, which will reach a diameter larger than 20 cm, and they occur in about 1 per 500,000 newborns. Despite its rarity, they may associate with severe abnormalities like spina bifida occulta, meningocele, club foot and hypertrophy or atrophy of deeper structures of a limb, Carney complex, premature aging syndromes, neurofibroma, vitiligo, lipoma and dysplasia of bilateral hip impact on the patient. ⋯ We highlight the importance of proper histopathological examination of the biopsy taken from the single huge nodule which revealed features of both neurofibroma and lipoma coexisting. The objective of this paper is to report a rare case with the clinical and pathologic findings.

Postoperative nausea and vomiting (PONV) is a frequent complication in postoperative period. The aim of the current meta-analysis was to assess the efficacy of dexmedetomidine on PONV. ⋯ The present meta-analysis indicates that dexmedetomidine shows superiority to placebo, but not to all other anesthetic agents on PONV. And this efficacy may be related to a reduced consumption of intraoperative opioids.

Impulse oscillometry (IOS) is a good method for measuring airway resistance. The aim of this study was to assess the diagnostic contribution of IOS combined with bronchial dilation test (BDT) when distinguishing between patients with asthma and those with chronic obstructive pulmonary disease (COPD). 870 were enrolled in the study including 561 patients with asthma, 100 patients with COPD and 209 patients with chronic coughing or normal subjects. All the participants underwent routine pulmonary function tests, IOS and BDT examination. ⋯ Our findings show, that X5, X25 and Fres may be useful for predictions and evaluations for COPD. And R5, X35 and Zrs may provide useful IOS parameters for asthma. IOS combined BDT could be useful diagnostic and differential diagnosis between asthma and COPD.
