目的 探讨经胼胝体-穹窿间入路切除第三脑室肿瘤术后，近期下丘脑反应的发生情况及相关因素，为防治第三脑室肿瘤术后下丘脑反应提供参考。 方法 回顾分析2003年1月－2008年12月经胼胝体-穹窿间入路切除的78例第三脑室肿瘤患者手术后近期（1个月内）下丘脑反应的发生情况，并将其按照肿瘤部位、病理性质、大小、血供、手术切除程度进行分类统计，用SPSS 13.0软件logistic 回归分析影响这些并发症的因素。 结果 78例术后下丘脑反应37例，发生率47.4%；死亡5例，下丘脑反应病死率为13.5%（5/37）。其中电解质糖代谢紊乱33例（42.3%），尿崩症27例（34.6%），激素水平低下16例（20.5%），高热6例（7.7%）。好转痊愈率：激素水平低下43.7%，其余均＞70%。第三脑室前部颅咽管瘤术后最容易发生下丘脑反应（P＜0.05）。 结论 经胼胝体-穹窿间入路切除第三脑室肿瘤术后近期存在程度不同的下丘脑反应，其发生与肿瘤部位、病理性质有密切关系。经积极治疗，大部分下丘脑反应能在术后1个月内好转甚至痊愈。
目的 探讨可逆性胼胝体压部病变的临床特征和致病机制。 方法 总结Pubmed和Springer数据库中2000年1月1日－2011年8月1日报道的年龄＞6岁的可逆性胼胝体压部病变患者的临床特征，分析该病可能的致病机制。 结果 14例患者中男7例，女7例；年龄（27.4 ± 15.6）岁，最小7岁，最大58岁；病因为发热、疫苗接种、感染、癫痫发作、接受抗癫痫药物或突然停用抗癫痫药治疗、接受四环素或氟尿嘧啶治疗、营养不良、慢性酒精消耗，临床症状出现率50%，为视幻觉、错觉、定向功能障碍、意识模糊、嗜睡、共济失调步态、急性尿潴留；可逆性胼胝体病变持续时间为（20.6 ± 14.5） d，最短2 d，最长50 d，影像学特征是T1加权成像低或等信号，T2加权成像、弥散加权成像高信号，表观弥散系数成像低信号，水抑制成像常无明显结构或信号异常发现，T1-钆对比剂增强成像无病灶强化。 结论 可逆性胼胝体压部病变病因多样，临床表现复杂，致病机制可能主要为低钠血症、低血糖、精氨酸血管加压素功能紊乱、感染或药物毒性等导致胼胝体压部细胞毒性水肿。
ObjectiveTo investigate the efficacy and safety of the phase Ⅰ corpus callosotomy in the treatment of adult refractory epilepsy. MethodsWe conducted a retrospective analysis of 56 adults with intractable epilepsy in Tangdu Hospital from January 2011 to July 2016.All patients were treated for the phase Ⅰ total corpus callosotomy, followed up 1~5 years after surgery. Results14 cases (25.0%) patients achieved complete seizure free after surgery, 19 cases (33.9%) whose seizures reduced more than 90%, 10 cases (17.9%) reduced between 50%~90%, 7 cases (12.5%) between 30%~50%, 6 cases (10.7%) decreased below 30%; Drop attacks of 47 cases (83.9%) patients disappeared. Postoperative complications occurred in 13 cases(23.2%), and most of them recovered well. 5 cases(8.9%) had long-term sensory disassociation, no serious complications and death. The percentage of patients reporting improvement in quality of life was 67.9%. ConclusionsFor patients with intractable epilepsy who can not undergo focal resection, Ⅰ phase total corpus callosotomy has a certain effect on reducing seizure frequency, eliminating drop attacks, and improving the quality of life.
Post-traumatic stress disorder (PTSD) is one of the common chronic diseases in psychiatry. It has a long course of disease which seriously affects patient’s life and work, and has a serious impact on social function. So far, the diagnosis of PTSD is limited to clinical symptom manifestations and physician experience, and no exact pathological substance basis is found, while the pathological substance basis is crucial for accurate diagnosis, selection of effective treatment methods, evaluation of treatment results, and assessment of disability. Head MRI is currently one of the most promising techniques to solve this problem. This paper reviews the progress in MRI research on brain structure changes in PTSD patients, in order to explore the possible future development directions.
Objective To investigate the clinical features and prognosis of acute isolated corpus callosum infarction. Methods The clinical and imaging data of patients with acute isolated corpus callosum infarction diagnosed in the Department of Neurology of Beijing Geriatric Hospital and the Department of Neurology of China-Japan Friendship Hospital from February 2017 to February 2021 were retrospectively selected. Patients were divided into groups according to infarction location, infarction size and prognosis. According to the infarction location, the patients were divided into single-site lesion group and multi-site lesions group. According to the infarction size, the patients were divided into large lesion group and small lesion group. According to the prognosis, the patients were divided into good prognosis group and poor prognosis group. The clinical characteristics, etiology and prognosis of these diseases were observed and analyzed. Results A total of 52 patients were included. Among them, there were 32 males (61.5%) and 20 females (38.5%), with an average age of (65.4±7.1) years. The most common risk factors were hypertension (44 cases, 84.6%), hyperlipidemia (32 cases, 61.5%), and diabetes (28 cases, 53.8%). The most common infarction site was splenium in the single-site lesion group (24 cases, 46.2%). The vast majority of patients (92.3%) had nonspecific clinical symptoms, and only 4 (7.7%) had corpus callosum disconnection syndrome. In the TOAST etiological classification, Large-artery atherosclerosis (LAA) was the most common (25 cases, 48.1%), followed by small-artery occlusion (14 cases, 26.9%), the responsible vascular lesions were the most common in the P1/P2 segment of posterior cerebral artery (10 cases) and the A1/A2 segment of anterior cerebral artery (9 cases). There was no significant difference in etiology between the groups with different infarction location and the groups with different infarction size (P>0.05). Forty-four cases (84.6%) had a good prognosis, and 8 cases (15.4%) had a poor prognosis. Combined with multiple risk factors, multiple involvement of lesions and large infarction size were associated with poor prognosis (P<0.05). Conclusions Acute isolated corpus callosum infarction is a rare type of ischemic stroke, with the most common involvement of splenium. Its clinical manifestations are mostly nonspecific, and a few may be manifested as disconnection syndrome. The etiology is mostly LAA, and the overall prognosis of such patients is good, and the poor prognosis may be related to the combination of multiple risk factors and the wide range of infarcts.
