The varied semiology of seizures in the context of small anterior temporal encephaloceles

Aims. Small encephaloceles of the anterior temporal pole have been increasingly recognised as an underlying epileptogenic substrate in patients with medically refractory epilepsy. The current report aims to expand on the current knowledge by emphasising that seizure semiology in such patients can vary significantly. Methods. Patients were selected from an epilepsy surgery database between 2012 and 2017. Results. Of the 143 patients who underwent epilepsy surgery, six patients had a temporal encephalocele. Four of these patients had stereo-EEG implantation. Of the four patients studied, each had a seizure semiology discordant with an ictal focus in the temporal lobe. Intracranial EEG assessment demonstrated, irrespective of this semiology, seizures originated from the anterior temporal pole. Seizures were observed to rapidly propagate to the orbitofrontal cortex, insula, temporo-occipital junction, and posterior language regions. Engagement of the mesial temporal structures could occur early or late, however, a good surgical outcome was achieved following a focused lesionectomy in either situation. Conclusion. The major finding was that seizures arising from anterior temporal encephaloceles can have an extra-temporal semiology. The varied clinical semiology and the rapid propagation to seemingly distant cortical regions could be explained by the connectivity of the anterior temporal lobe.

急性心肌梗死后外周血单个核细胞表面CD147与基质金属蛋白酶-9 mRNA表达的相关性

目的：基质金属蛋白酶在急性心肌梗死后的心室重构中起着重要作用，但其调节机制目前尚未明确。实验拟通过动物模型的建立及体外细胞培养，观察急性心肌梗死后单个核细胞表面CD147与心肌成纤维细胞基质金属蛋白酶-9 mRNA表达的关系。 方法：实验于2006—08／2007-06在河北省人民医院临床实验中心完成。实验材料：SD大鼠及SD仔鼠（出生1～3d）购自河北医科大学试验动物中心。实验过程中对动物处置符合动物伦理学标准。实验方法：①将30只大鼠随机分为急性心肌梗死组（n=15）和假手术组（n=15），假手术组只过线不结扎。流式细胞分析法检测大鼠术后24h外周血单个核细胞表面CD147表达。②选择SD仔鼠制备心肌成纤维细胞。将单个核细胞与心肌成纤维细胞以细胞数0．5：1，1：1，2：1混合培养24h后，半定量反转录一聚合酶联反应法检测基质金属蛋白酶-9 mRNA表达。当单核细胞与心肌成纤维细胞2：1混合时，加入CD147单克隆抗体1，2，4μL/L，培养24h后检测基质金属蛋白酶-9 mRNA表达。 结果：①急性心肌梗死后外周血单个核细胞表面CD147表达明显增加。②单个核细胞与心肌成纤维细胞混合培养，随着单个核细胞比例的增加，心肌成纤维细胞基质金属蛋白酶-9 mRNA表达增加。③在单个核细胞与心肌成纤维细胞2：1混合培养体系中，随着加入CD147单克隆抗体浓度的增加，基质金属蛋白酶-9 mRNA生成减少。 结论：急性心肌梗死后单个核细胞表面CD147表达明显增加，对心肌成纤维细胞基质金属蛋白酶-9生成起上游调节作用。     

Psychological problems in gastroenterology outpatients: A South Australian experience. Psychological co-morbidity in IBD,IBS and hepatitis C

Background

In independent studies, IBD, IBS and HCV have each been associated with a substantially increased risk of psychological problems such as depression and anxiety and impairment of quality of life compared to the general healthy population. However, the relative psychological burden for each of these diagnoses is unknown as it has never been compared contemporaneously at one institution. Current local data are therefore needed to enable an evidence-based allocation of limited clinical psychological resources.

Methods

Overall, 139 outpatients (64 IBD, 41 HCV, and 34 IBS) were enrolled in this cross-sectional study. The HADS, SCL90, SF-12 and appropriate disease-specific activity measures were administered. Differences between groups were assesed with ANOVA, the Chi-Square test and the independent samples t-test (two-tailed).

Results

Each of the three groups had significantly lower quality of life than the general population (p < 0.05). Overall, a total of 58 (42%) participants met HADS screening criteria for anxiety and 26 (19%) participants for depression. The HCV group had a significantly higher prevalence of depression than either of the other groups (HCV = 34%, IBS = 15% and IBD = 11%, p = 0.009). In the SCL90, the three disease groups differed on 7 out of 12 subscales. On each of these subscales, the HCV group were most severely affected and differed most from the general population.

Conclusion

Patients with these common chronic gastrointestinal diseases have significant impairment of quality of life. Anxiety is a greater problem than depression, although patients with HCV in particular, should be regularly monitored and treated for co-morbid depression. Evaluation of specific psychological interventions targeting anxiety is warranted.
