Long-Term Subdural Strip Electrocorticographic Monitoring of Ictal Déjà Vu

Summary: We report a series of 8 patients with ictal déjà vu. Subdural strip electrocorticographic (ECoG) monitoring localized the ictal epileptogenic focus as follows: right (n = 6) and left (n = 2) mesiotemporal lobe. In all 8 patients, the left hemisphere was dominant for language function based on intracarotid amytal testing. In 6 right-handed patients, ictal déjà vu was associated with a right temporal lobe focus. However, in the 2 left-handed patients, the ictal focus was left temporal lobe. Although ictal déjà vu localizes the epileptic focus to temporal lobe, this experiential phenomenon appears to lateralize to the hemisphere nondominant for handedness.     

Kabuki make-up syndrome associated with West syndrome

A Japanese boy with Kabuki make-up syndrome associated with West syndrome is reported. He developed periodic tonic spasms at 6 months of age while his electro-encephalogram also revealed hypsarrhythmia. Although only a few previously reported cases of Kabuki make-up syndrome have been associated with epilepsy, it is likely that epileptic seizures are another primary feature of Kabuki make-up syndrome.

Temporal arteritis presenting with scalp ulceration

We report the case of a 75-year-old-woman who presented with bilateral scalp ulcerations and blindness, accompanied by severe headache and scalp tenderness, due to bilateral temporal arteritis without systemic involvement. A biopsy taken from the border of an ulceration showed evidence of giant cell arteritis. She was treated with oral prednisone, 60 mg per day. The ulcerations healed in a few weeks but the vision loss was irreversible. This case highlights for temporal arteritis the importance of accurate and timely diagnosis as well as the need for prompt therapy with systemic steroids in order to avoid major complications, namely loss of vision. It also demonstrates that scalp necrosis and ulcerations are skin signs associated with a poor prognosis.     

颞叶癫痫的MRI与临床分析

目的：探讨颞叶癫痫的MRI表现、临床特征及治疗。方法：利用MRI辅以EEG诊断并定位32例颞叶癫痫（TLE），抗癫痫药(AED)正规治疗2年控制不良并外科手术治疗。结果：32例TLE患全部海马萎缩，2例双侧；高信号26例。诊断海马硬化26例。24例手术病理结果证实与MRI结果相符。手术后加药物治疗，效果满意15例，显7例，良好2例。结论：海马萎缩与信号增高是硬化常见MRI表现，有诊断价值。MRI有助于TLE定位诊断。手术加药物是治疗顽固性TLE之重要方法。

Ictal Single-Photon Emission Computed Tomography Imaging in Extra Temporal Lobe Epilepsy Using Statistical Parametric Mapping

PURPOSE: To examine the application of statistical parametric mapping (SPM) to analyze ictal single-photon emission computed tomography (SPECT) scans in surgical candidates with extratemporal lobe epilepsy. METHODS: The authors selected patients who underwent successful ictal SPECT acquisition in the process of surgical treatment of intractable partial epilepsy. Thirteen patients were identified who met inclusion criteria for confident seizure localization from either intracranial electroencephalogram recordings or epilepsy surgery outcome. In these cases, ictal scans were registered to an in-house-developed normal SPECT atlas composed of 14 spatially normalized brains of normal subjects. SPM96 was used to test on a voxel-by-voxel basis for statistically significant increases in blood flow associated with each patient's ictal scan. The results were then mapped back onto the patient's magnetic resonance image (MRI) for final interpretation. Statistical parametric mapping (SPM) analysis of ictal SPECT scans was compared to both conventional visual interpretation and the analysis of subtraction ictal SPECT co-registered to MRI (SISCOM). RESULTS: Ten of 13 patient scans showed localizing focal ictal increases in regional cerebral blood flow, all of which were concordant with ultimate epilepsy localization. Of the 3 cases not localized with SPM, 1 was localized by conventional visual interpretation and another, not localized by visual interpretation, was correctly localized with SISCOM. Two cases not localized by SISCOM were localized by both visual and SPM analysis. CONCLUSIONS: This work provides supportive evidence for proof of principle that SPM can be used to provide objective, accurate analysis of ictal SPECT scans in patients with extratemporal lobe epilepsy.     

Following Catastrophic Epilepsy Patients from Childhood to Adulthood

Summary:  As patients with catastrophic epilepsies move from childhood to adulthood, evolving and innovative therapeutic regimens are often required. However, the goal of providing the best quality of life while minimizing both seizures and side effects remains the same. Clinicians can develop appropriate care plans by being aware of patients' changing needs. Clinical symptoms of the catastrophic epilepsies may change over time; by understanding the natural history of a patient's condition, clinicians can help ease the transition from childhood to adulthood. Additionally, as children with catastrophic epilepsies become adults, medical issues (e.g., medication side effects, tolerance, and dependence) and nonmedical issues (e.g., guardian/caretaker issue, group home applications, and respite care options) must be considered when developing strategies for patient care. Regular assessment of patients, the development of emergency plans, and maintenance of consistency in the delivery of care are also important issues to consider. Finally, a multidisciplinary care plan that incorporates resources from health-care practitioners, social service professionals, and community agencies can be valuable in optimizing treatment for patients with catastrophic epilepsies.     

托吡酯对慢性癫(癎)大鼠海马碱性成纤维细胞生长因子表达的影响

目的研究托吡酯（TPM）对慢性癫痫大鼠海马碱性成纤维细胞生长因子（bFGF）表达的影响。方法制作戊四氮（PTZ）慢性癫痫点燃大鼠模型，分为PTZ组、TPM组及正常对照组，每组又以5d、10d、15d3个时间点各分为3小组。免疫组化法观察各组海马CAl、CA3区及齿状回bFGF表达，HE染色观察病理形态学改变。结果（1）行为学观察：PTZ组和TPM组在癫痫发作上无明显差别。（2）bFGF表达：①各组齿状回区bFGF表达：PTZ组和TPM组各时点表达不断增高，与正常对照组比较差异有统计学意义（均P〈0．01），尤以10d及15d时增高更明显，与5d时比较差异有统计学意义（均P〈0．05）。②各组CAl区bFGF表达：PTZ组各时点均有明显表达，且随时间延长而表达不断增高，各时点比较差异有统计学意义（均P〈0．01），与正常对照组比较差异有统计学意义（均P〈0．01）；TPM组在5d时与正常对照组比较差异有统计学意义（P〈0．01），而10d、15d时逐渐下降，接近正常对照组水平。③各组CA3区bFGF表达：5d时3组比较差异无统计学意义。但PTZ组和TPM组在10d时与正常对照组比较差异有统计学意义（P〈0．01），PTZ组在15d时和TPM组及正常对照组比较差异有统计学意义（均P〈0．01）。（3）病理形态学改变：PTZ组和TPM组的海马CAl、CA3区尤其是CAl区可见较多神经元发生变性和坏死，PTZ组更显著。结论PTZ点燃过程中海马bF-GF表达增高，尤其在CAl区，且随时间延长有表达不断增高的趋势。TPM可能通过减少海马神经元损伤而明显下调海马CAl、CA3区bFGF的表达。
