目的 探讨延髓肿瘤的治疗策略，以达到最佳预后。 方法 回顾分析2007年1月－2010年12月19例延髓肿瘤患者的临床资料，其中18例经外科手术治疗和病理证实，1例通过影像学确诊。 结果 12例血管网状细胞瘤中，11例手术全切，1例手术次全切；2例室管膜瘤均手术全切；2例海绵状血管瘤分别手术全切及伽马刀治疗；3例胶质瘤均手术部分切除。18例手术治疗患者术后神经功能障碍明显好转者13例，无明显变化者3例，2例因术后严重并发症死亡；1例伽马刀治疗患者症状好转。术后随访6～48个月，平均24个月。11例恢复工作，4例生活可自理，2例因肿瘤复发死亡。结论 术前通过MRI检查、术中神经电生理监测及熟练的显微外科技术是外科治疗优势，伽马刀治疗延髓较小肿瘤有着损伤小的优点，因此制定合理的治疗策略有利于提高患者生存质量。
ObjectivesTo identify the clinical characteristics and prognosis for CRKP (Carbapenem-resistant Klebsiella pneumonia, CRKP) infection among ICU patients in the Second Affiliated Hospital of Anhui Medical University. MethodsWe conducted a retrospectively analysis in which 19 patients infected by CRKP with another 21 CSKP (Carbapenem-sensitive Klebsiella pneumoniae, CSKP) infected patients from January 2017 to April 2018. Risk factors for CRKP infection were assessed. ResultsThe lower respiratory tract is the most common site of CRKP infection in our department. CRKP infection was associated with several clinical symptoms, particularly a higher incidence of sepsis shock (χ2=8.338, P=0.004), more application of the combined medicine (χ2=26.3, P<0.001), prolonged hospital stays (χ2=–2.217, P=0.027) and more expenses on antibiotics (χ2=12.855, P=0.005), and the declined survival rates in 14 days (χ2=4.269, P=0.039) and 21 days (χ2 =5.647, P=0.017). The resistance rate of CRKP strains was high, however no resistance to tegafycline was found. The risk factors of CRKP infection included three generations of cephalosporin and/or hydrocarbonase antibiotics exposure (χ2 =6.388, P=0.041), exposure time of three generations of cephalosporin (U=–2.187, P=0.029), exposure time of hydrocarbonase antibiotics (U=–2.103, P=0.035), tracheal intubation (χ2=6.352, P=0.012), tracheotomy (χ2 =4.821, P=0.028), SOFA score (t=4.505, P<0.001) and Charlson comorbidity index (t=3.041, P=0.004). The SOFA score was the only factor independently associated with CRKP bacteremia (P=0.02). ConclusionsCRKP infections in ICU directly affect the course of disease, survival time and treatment expenses of patients. Therefore, monitoring bacterial resistance, rational use of antibiotics, and protection of the immune function are of great significance for prevention and treatment of CRKP infection.
