Intrapulmonary metastasis developing eighteen years after complete resection of thymoma

We present a case of intrapulmonary metastasis developing 18 years after complete resection of thymoma. An 8 mm nodule in the lower lobe of the left lung was noted on chest X-ray in a 76-year-old woman who had undergone complete resection of Masaoka’s stage II thymoma 18 years earlier. Since the nodule grew to 17 mm during a 2-year follow-up, wedge resection was performed. The lesion was histologically diagnosed as an intrapulmonary metastasis from thymoma. Extremely late recurrence after complete resection of thymoma is discussed.     

Relationship between the superior attachment type of uncinate process and presence of agger nasi cell: A computer-assisted anatomic study

OBJECTIVE: The uncinate process (UP) is an important anatomic landmark in frontal recess surgery. Its superior attachment shows great anatomic variability. The agger nasi (AN) cell is another important structure that affects frontal recess anatomy and there is a close neighborhood between them. The aim of this study was to investigate the relationship between superior attachment type of UP and the presence of AN cell. STUDY DESIGN: A retrospective anatomical study. METHOD: Computed tomography scans were evaluated of 486 sides of 243 patients who had had paranasal sinus. In 125 (26%) sides, the superior attachment of the UP could not be identified. In the remaining 361 (74%) sides, the prevalence of superior attachment of UP types and the presence of AN cell in each side were recorded. The results were evaluated with chi2 test. RESULTS: The AN cell was found in 290 (80.3%) of 361 sides. The prevalence of AN cell according to superior attachment of UP types were 79.6% for type 1/2, 90.1% for type 3, 71.4% for type 4, 86.5% for type 5, and 83.3% for type 6. The presence of AN cell according to superior attachment types of UP was not statistically significant (chi2= 3.54, P = 0.315). CONCLUSIONS: The AN cell was found to be present in 80.3% of the cases. However, the relationship between the presence of the AN cell and the superior attachment types of UP was not statistically significant.     

The importance of two-step tuberculin skin testing for newly employed healthcare workers.

At the time of hire, 4059 of 6522 healthcare workers required a 2-step tuberculin skin test; 114 workers (2.8%) demonstrated a boosted reaction after the second step. Boosted reactions were significantly associated with male sex and older age. A verbal history of previous tuberculin skin test results was not a reliable indicator of baseline tuberculin skin test status at the time of hire.     

采用泌尿道前列腺切除器经肛门内镜切除直肠肿瘤：131例患者应用的经验

目的：直肠腺瘤和其他疑似为良性的病变应用经肛门内镜切除术并未普及。该项研究旨在评估经肛门内镜切除术的效能和安全性。方法：回顾性研究分析在1993-2004年之间3所斯德哥尔摩医院中经肛门内镜切除术的患，内容包括患自身及病变特性、并发症、随访时间和复发率。结果：180例中共131例行经肛门内镜切除术。160例经组织学诊断为腺瘤，12例为癌瘤，其余8例分别为增生、纤维化或正常黏膜。直肠腺瘤患中，77例仅行单次经肛门内镜切除术，16例因巨大腺瘤而多次行该手术，27例因复发而需另行经肛门内镜切除术或其他手术。中位复发时间为7个月，但未出现直肠癌。16例手术患出现并发症。2例患必须行Hartman手术，1例因肠穿孔，另1例因出血。手术期间无死亡。未复发的中位随访期为32个月（极差0—67）。[编按]
