Anti-goat antibodies as a rare cause of high gonadotropin levels during menopausal transition

Abstract

Objective: To understand the origin of extremely high gonadotropin levels in a perimenopausal woman.

Methods: A 52-year-old woman with a 2?months of amenorrhea followed spontaneous menstrual cycles recovery was referred to our outpatient clinic with elevated follicle-stimulating hormone (FSH, 483 mUI/ml), luteinizing hormone (LH, 475 mUI/ml) and prolactin (PRL, 173?ng/ml). She was known to take levosulpiride. The gonadotropin levels did not fit with the clinical features.

Results: A gonadotroph tumor was ruled out. Further analysis confirmed constantly high FSH, LH and PRL levels. The measurements were repeated using different analytical platforms with different results. After serial dilutions, nonlinearity was present suggesting an immunoassay interference. After post-polyethylene glycol recovery, hormone levels appeared in the normal range. Anti-goat antibodies were recognized in the serum of the patient.

Conclusions: This case report shows a case of falsely abnormal high gonadotropin and PRL levels in a woman during menopause transition. In the clinical practice the evaluation of gonadotropin profile is not recommended at this age, but the abnormal levels stimulated further evaluation. An interference in the assay due to anti-goat antibodies resulted in abnormally high level of FSH and LH. A strict collaboration between clinicians and the laboratory is needed, when laboratory findings do not correspond to clinical findings.     

Longer Operative Time Results in a Higher Rate of Subsequent Periprosthetic Joint Infection in Patients Undergoing Primary Joint Arthroplasty

Background

Whether prolonged operative time is an independent risk factor for subsequent surgical site infection (SSI) and periprosthetic joint infection (PJI) following total joint arthroplasty (TJA) remains a clinically significant and underexplored issue. The aim of this study is to investigate the association between operative time and the risk of subsequent SSI and PJI in patients undergoing primary TJA.

风险管理在护理管理中的应用分析

目的:探讨风险管理在护理管理中的应用效果。方法:选取2012年8月~12月实施风险管理前于我科接受手术治疗患者180例作为对照组;2014年1月~5月于我科接受手术治疗的210例患者作为观察组,对实施护理风险管理前后患者对护理工作者工作质量的评价、护理工作者应急能力等指标进行比较。结果:1护理质量:风险管理应用到护理管理中,患者投诉情况、护理不良事件发生情况以及满意情况均优于应用前(P<0.05)。2工作质量:风险管理应用后,护理工作人员在责任心、沟通能力、服务态度以及操作熟练程度方面评分均显著高于应用前,P<0.05。3风险意识:风险管理应用后,护理工作者对于风险管理、风险因素的认识,风险管理态度以及应急能力均较之于应用前显著提高。结论:风险管理应用于护理管理,可降低护理纠纷,提高患者护理满意度。
