  • SEEG-guided radiofrequency thermocoagulation in the treatment of bilateral posterior cortex epilepsy: a case report and review of the literature

    ObjectiveTo explore the clinical value of SEEG-guided radiofrequency thermocoagulation therapy in patients with posterior cortex epilepsy.MethodsA case of epilepsy secondary to viral encephalitis was reported in this paper, SEEG implantation confirmed that the seizure began in bilateral posterior head, and the right posterior head was the main area of disabling lesion. After a series of complete preoperative neuropsychological assessment, the right posterior head was found to have functional retention. Therefore, we used a minimally invasive radiofrequency thermocoagulation therapy to damage epileptic foci.ResultsThe patient were followed up for 2 years after operation, the seizure frequency were significantly reduced, and the patients did not show symptoms of functional loss.ConclusionPosterior cortex epilepsy is common in neonates with brain injury. The localization and lateralization of operation is difficult because its EEG showed bilateral discharges, or the seizures start from both sides of posterior head, meanwhile, posterior head involves functional areas, which makes the operation even more difficult. This minimally invasive treatment destroys the lesion and maximizes the protection of the patient's functional areas, which provides a new surgical approach for bilateral posterior cortex epilepsy in the future, especially for symptomatic epilepsy caused by hypoxic-ischemic brain injury and encephalitis.

  • The advantage of diffusion weighted imagin technique in the toxicity detection of vigabatrin

    ObjectiveTo explore the differences in the detection of vigabatrin-associated brain abnormalities on MRI by different MRI sequences, so as to further guide the clinical understanding of VABAM and improve the appropriate imaging sequences. MethodsA total of 353 patients with infantile spasm or epileptic spasm who were admitted to the Epilepsy Center of Yuquan Hospital of Tsinghua University from January 2020 to January 2023 were retrospectively included. MRI was performed in 131 cases, including 3D T1, T2, T1- fluid-attenuated inversion recovery sequence (FLAIR) images, DWI and ADC sequences, of which 65 cases taking VGB. We aim to evaluate the detection of vigabatrin-associated brain abnormalities on MRI by different MRI sequences in these children. Results Among the 65 patients, VABAM was detected in 23 cases, the detection rate was 35.4%. The average dosage of vigabatrin was 100.73±35.54 mg/(kg·d). The positive detection rates of VABAM were 95.7% in DWI sequence, 26.1% in ADC sequence, 21.3% in FLAIR sequence, 4.3% in T2 sequence and 0 in T1 sequence. The detection rate of ADC sequence was significantly different from DWI sequence and T1 sequence, but not from T2 sequence and FLAIR group. ConclusionDWI sequence has irreplaceable advantages in the detection rate of VABAM. Therefore, for patients with infantile spasm and epileptic spasm who take vigabatrin, we should try our best to add DWI sequence scanning to improve the positive detection rate and avoid clinical symptoms, so as to avoid further brain damage.

  • Analysis of the status of evidence for disease burden research

    ObjectivesTo conduct a bibliometric analysis to research the status of disease burden domestically and overseas so as to understand the status of diseases burden, and to provide scientific and reasonable reference for health disease prevention, control strategies formulation and future research.MethodsPubMed, Web of Science, EMbase, The Cochrane Library, WanFang Data, CBM and CNKI databases were electronically searched to collect literature on disease burden from inception to October, 2018. Two reviewers independently screened literature and extracted data. EndNote X7 software was used for literature management, Excel 2016 software and VOS viewer software were also used to analyze data. Literature was classified by the aspects of literature publication characteristics, diseases, background areas, influencing factors, evaluation indicators and poverty caused by illness.ResultsA total of 325 studies were included in the bibliometric analysis. 41 articles (12.6%) were published in journals indexed by SCIE; original research evidence accounted for 97.0% (315 articles); 272 articles were from China (83.7%). The main diseases involved were malignant tumors (58 articles, 17.8%), diabetes (29 articles, 8.9%) and hypertension (24 articles, 7.4%). Factors affecting the disease burden primarily included hospitalization days (9 articles, 2.8%), complications (5 articles, 1.5%), delays in treatment (5 articles, 1.5%), and economic income (4 articles, 1.2%). Sixity-one articles (18.8%) reported poverty due to illness, and related diseases were chronic obstructive pulmonary disease (12 articles, 3.7%), hypertension (10 articles, 3.1%), diabetes (10 articles, 3.1%), malignant tumors (9 articles, 2.8%) and hepatitis B (6 articles, 1.8%).ConclusionsAt present, the disease burden research are focusing more on the burden of chronic non-communicable diseases such as malignant tumors, hypertension, diabetes, cardiovascular and cerebrovascular diseases in developing countries and regions. Medical costs vary from different diseases and treatment, different demographic characteristics of patients, and the coverage medical security of different population are the primary reasons for the " expensive in medical treatment” of current residents and the heavy burden of disease. DALY and total direct medical expenses are the main evaluation indexes of epidemiological burden and economic burden of disease, respectively. Future researches should focus on strengthening the scientific nature of study design to improve the quality of research, as well as paying more attention to diseases and aspects that are rarely involved, such as major diseases caused by poverty due to illness, comprehensive analysis of multiple diseases and aspects of health investment measurement, and comprehensively use the evaluation indicators of disease burden to strengthen the research on the comparability index of disease economic burden.

  • SEEG-guided radiofrequency thermocoagulation ablation for tuberous sclerosis-associated epilepsy

    ObjectiveTo study the therapeutic efficacy of stereoelectroencephalography (SEEG)-guided radiofrequency thermo-coagulation ablation (RF-TC) in the treatment of tuberous sclerosis (TSC) related epilepsy and to investigate the prediction of the therapeutic response to SEEG-guided RF-TC for the efficacy of the subsequent surgical treatment. MethodsWe retrospectively analyze TSC patients who underwent SEEG phase II evaluation from January 2014 to January 2023, and to select patients who underwent RF-TC after completion of SEEG monitoring, study the seizure control of patients after RF-TC, and classify patients into effective and ineffective groups for RF-TC treatment according to the results of RF-TC treatment, compare the surgical outcomes of patients in the two groups after SEEG, to explore the prediction of surgical outcome by RF-TC treatment. Results59 patients with TSC were enrolled, 53 patients (89.83%) were genetic detection, of which 28 (52.83%) were TSC1-positive, 21 (39.62%) were TSC2-positive, and 4 (7.54%) were negative, with 33 (67.34%) de novo mutations. The side of the SEEG electrode placement: left hemisphere in 9 cases, right hemisphere in 13 cases, and bilateral hemisphere in 37 cases. 37 patients (62.71%) were seizure-free at 3 months, 31 patients (52.54%) were seizure-free at 6 months, 29 patients (49.15%) were seizure-free at 12 months, and 20 patients (39.21%) were seizure-free at 24 months or more. 11 patients had a seizure reduction of more than 75% after RF-TC, and the remaining 11 patients showed no significant change after RF-TC. There were 48 patients (81.35%) in the effective group and 11 patients (18.65%) in the ineffective group. In the effective group, 22 patients were performed focal tuber resection laser ablation, 19 cases were seizure-free (86.36%). In the ineffective group, 10 patients were performed focal tuber resection laser ablation, only 5 cases were seizure-free (50%), which was a significant difference between the two groups (P<0.05). ConclusionsOur data suggest that SEEG guided RF-TC is a safe and effective both diagnostic and therapeutic treatment for TSC-related epilepsy, and can assist in guiding the development of future resective surgical strategies and determining prognosis.

  • Clinical summary and analysis of patients with refractory epilepsy in tuberous sclerosis complex with peripheral blood gene negative

    ObjectiveTuberous sclerosis complex (TSC) is a multisystem disease, which often manifests as refractory epilepsy in the nervous system and multifocality in Magnetic resonance imaging (MRI). We summarized patients with TSC whose peripheral blood gene test was negative,and analyzed their medical history, EEG, MRI and postoperative conditions. MethodsWe summarized and analyzed 205 patients with TSC diagnosed clinically and pathologically and underwent surgery from April 2008 to February 2024. 11 patients with TSC whose peripheral blood gene test was negative and underwent surgery were screened out.All patients underwent gene examination, MRI and long-range video EEG monitoring. All patients underwent detailed preoperative evaluation and direct resection surgery, intracranial electrode thermocoagulation surgery or laser surgery. ResultsOf the 11 patients with peripheral blood gene test negative, 11 (100%) patients achieved Engel Ⅰ within 1 year after surgery, and 10 (91%) patients achieved Engel Ⅰwithin 2 years. The median age of onset of 11 patients was 6 months, and 8 patients (73%) had onset less than 1 year old. All patients had multiple nodules in the brain. Except for the brain, the changes of the other organs were polycystic kidney and skin changes in 2 patients, skin changes in 8 patients, and normal in 1 patients. ConclusionTSC patients with peripheral blood gene negative who have young onset age, frequent seizures, and multiple nodules on MRI often present with refractory epilepsy. However, the postoperative effect is good, and the postoperative EEG of most patients is normal.
