BACKGROUND: This study was conducted to confirm the predictive power of preoperative pulmonary functions tests (PFTs) for intra- and post-operative cardiopulmonary complications during corrective surgery for scoliosis. METHODS: A retrospective review of hospital charts of patients who underwent surgical correction for scoliosis and/or kyphosis at our medical center between September 2002 and September 2008 was performed. RESULTS: A total of 141 patients were enrolled in this study. The overall intra- and post-operative cardiopulmonary complication rate was 33.3% (47/141). There were 32 and 19 complications related to pulmonary issues (22.7%) and cardiovascular complications (13.5%), respectively. The complication rate of neuromuscular scoliosis (NMS) was 47.3% (35/74), while that of non-neuromuscular scoliosis (NNMS) was 17.9% (12/67). The cardiopulmonary complication rates of groups with FEV1 volumes below 1 L, 1-1.5 L, 1.5-2 L and over 2 L were 66.7% (18/27), 43.3% (13/30), 20.0% (7/35) and 18.4% (9/49), respectively. The group with FEV1 volumes below 1 L showed a significantly increased risk when compared to the group with FEV1 volumes over 2 L (P<0.05, Odds ratio = 5.15, multivariate logistic regression test). The cardiopulmonary complication rates of groups with FVC volumes below 1 L, 1-1.5 L, 1.5-2 L and over 2 L were 70.8% (17/24), 37.5% (9/24), 33.3% (11/33) and 16.7% (10/60), respectively. Additionally, the group with FVC volumes below 1 L showed significantly increased risk when compared to a group with FVC volumes greater than 2 L (P<0.001, Odds ratio = 8.0, multivariate logistic regression). CONCLUSIONS: The correction for NMS carries a higher complication rate than NNMS. Intra- and post-operative cardiopulmonary complication rates of a group with FEV1 or FVC volumes below 1 L were higher than the rates of groups with FEV1 and FVC volumes greater than 2 L.

A retrospective review of 546 consecutive female patients who had undergone mammographically controlled needle localizations was performed to assess the effectiveness of the technique and to analyze the number and the characteristics of the criteria malignancies found in this group. Localization biopsy was recommended if one or more of the following criteria were present: evidence of a mass, microcalcifications, parenchymal distortion, and/or spiculation. Of those 546 patients who had undergone specimen mammography after needle localization biopsy, a lesion was detected on 544 cases and missed in 2 cases(0.3%). Fifty-five cancers were detected(10.1%) Histologically, the cancers included 23 invasive and 32 in-situ tumors. The predominant histologic cell type was ductal in origin with only three having lobular characteristics. Postoperative pathologic findings of the lymph nodes showed 3 of the 55 were positive for metastases. In summary, the technique of preoperative needle localization in this series had a 99.7% success rate. The cancer detection rates for a 'mass with a microcalcification', a 'microcalcification', and a 'mass' were 17.0, 14.0, and 5.1% respectively. As a conclusion, needle localization biopsy is a safe and effective method for definitely diagnosing nonpalpable breast lesions.
