On imaging, inflammatory demyelinating pseudotumor appears very similar to intramedullary tumors such as gliomas. It is often misdiagnosed as intramedullary tumor and surgically resected. In view of this, the clinical and magnetic resonance imaging manifestations and the pathological fea- tures of 36 cases of inflammatory demyelinating pseudotumer in the spinal cord were retrospec- tively analyzed and summarized. Most of these cases suffered from acute or subacute onset and exhibited a sensofimotor disorder. Among them, six cases were misdiagnosed as having intrame- dullary gliomas, and inflammatory demyelinating pseudotumor was only identified and pathologically confirmed after surgical resection. Lesions in the cervical and thoracic spinal cord were common. Magnetic resonance imaging revealed edema and space-occupying lesions to varying degrees at the cervical-thoracic junction, with a predominant feature of non-closed rosette-like reinforcement （open-loop sign）. Pathological examination showed perivascular cuffing of predominantly dense lymphocytes, and demyelination was observed in six of the misdiagnosed cases. These re- sults suggest that tumor-like inflammatory demyelinating disease in the spinal cord is a kind of special demyelinating disease that can be categorized as inflammatory pseudotumor. These solitary lesions are easily confused with intramedullary neoplasms. Patchy or non-closed reinforcement （open-ring sign） on magnetic resonance imaging is the predominant property of inflammatory de- myelinating pseudotumor, and inflammatory cell infiltration and demyelination are additional patho- logical properties.展开更多

Neurologic disorders associated with IBD are not frequent, being reported in 3% of patients, but they often represent an important cause of morbidity and a relevant diagnostic issue. In addition, the increasing use of immunosuppressant and biological therapies for IBD may also play a pivotal role in the development of neurological disorders of different type and pathogenesis. Hence, we provide a complete and profound review of the main features of neurological complications associated with IBD, with particular reference to those related to drugs and with a specific focus on their clinical presentation and possible pathophysiological mechanisms.展开更多

However, little is known about idiopathic inflammatory demyelinating diseases （IIDDs） of the central nervous system （CNS） in patients following alIo-HSCT. Methods A nested case-control study was conducted in a large cohort of 1365 patients, who underwent alIo-HSCT at the Institute of Hematology and Peking University People＇s Hospital, between January 2004 and December 2009, 36 patients of whom developed CNS IIDDs. Kaplan-Meier method, univariate and multivariate Cox regression were applied in our statistical analysis using SPSS 16.0. Results The cumulative incidence of all cases of IIDDs at 6 years posttransplantation was 3.6%. Thirty-five patients （97.2%） suffered IIDDs after transplantation, 16 patients （44.4%） between day 0 to day 100 post-transplantation, 10 patients （27.8%） between day 100 to 1 year post-transplantation, and 9 patients （25.0%） 1 year post-transplantation. Multivariate regression analysis identified donor type （P=0.031）, infection （P=0.009）, and acute lymphatic leukemia （P=0.017） as independent risk factors for posttransplantation IIDDs. The median survival time of patients with IIDDs was 514 days after transplantation （95% CI： 223-805）. Survival at 6 years was significantly lower in patients who developed the diseases compared to those who did not （26.6% vs. 73.5%, P 〈0.001）. Of the 36 patients experiencing IIDDs, 58.3% （n=21） died. The causes of death were graft-versus-host disease （GVHD） （n=4）, underlying disease relapse （n=3）, infections （n=12）, and other causes （n=2）. Conclusions IIDDs is an uncommon but serious complication of alIo-HSCT, especially in patients with a primary diagnosis of acute lymphatic leukemia, mismatched transplants, and infections. Our study results indicate that patients with IIDDs tend toward a poor prognosis following alIo-HSCT.展开更多

文摘目的 探究入院-出院-随访一站式护理服务模式在中枢神经系统特发性炎性脱髓鞘病(central nervous system-idiopathic infl ammatory demyelinating diseases,CNS-IIDDs)患者中的应用效果。方法 选择2021年1月—2022年6月收治的60例CNS-IIDDs患者作为研究对象,按照组间基线资料均衡可比的原则分为对照组和观察组,各30例。对照组使用常规护理服务模式;观察组在对照组基础上实施入院-出院-随访一站式护理服务模式。采用疾病不确定感成人量表(Mishel Uncertainty in Illness Scale,MUIS-A)和疾病不确定感社区量表(Mishel Uncertainty in Illness Scale Community Form,MUIS-CF)评价两组患者疾病不确定感,采用Morisky服药依从性量表(Morisky Medication Adherence Scale,MMAS-8)评价患者的用药依从性,采用焦虑自评量表(Self-Rating Anxiety Scale,SAS)和抑郁自评量表(Self-Rating Depression Scale,SDS)评价患者的心理状态,采用简明健康调查量表(the Mos Item Short From Health Survey,SF-36)和满意度评价量表分别评价患者的生存质量及护理满意度。结果 干预后,观察组患者MUIS-A、MUIS-CF、SAS、SDS评分均低于对照组,差异均有统计学意义(P<0.05);观察组患者依从性高于对照组,生存质量各项维度评分和护理满意度总分均高于对照组,差异均有统计学意义(P<0.05)。结论 入院-出院-随访一站式护理服务模式可以降低CNS-IIDDs患者疾病不确定感,提升其用药依从性,有利于改善患者的心理状态和生存质量,有效提升患者护理满意度。
