SUMMARYTo search for a method for treatment of bilateral temporal lobe epilepsy (BTLE), we report one patient with BTLE experienced bilateral stereotactic radiofrequency amygdalohippocampectomy (SAHE). Neuropsychological examinations were performed before and 5 days, and 6, 18, and 48 months after operation. No seizure occurred in the follow-up time, and no long-term memory and intelligence deficits were found except for a transient decline of the scores immediately after operation. Because severe damage of memory could be caused by bilateral resection surgery, bilateral SAHE should be considered as a possible approach for the treatment of BTLE. However, further studies with accumulation of cases are needed, especially in the detailed assessment of neuropsychological function.
Background. Some patients with temporal lobe epilepsy have bilateral discharges and a few have bilateral medial temporal sclerosis. Stereotactic bilateral radiofrequency thermocoagulation (RFTC) of the amygdalohippocampal complex can terminate seizures or reduce seizure severity in patients with bilateral medial temporal lobe epilepsy (BMTLE).
Aim. To explore the safety and efficacy of bilateral transfrontal minimal RFTC of the amygdalohippocampal complex for the treatment of BMTLE.
Methods. A total of 12 BMTLE patients were treated with bilateral transfrontal minimal RFTC of the amygdalohippocampal complex under limited coagulations. The volumes of coagulated lesions were less than 0.6 cm3 Clinical outcomes were evaluated using Engel's classification, the Liverpool Seizure Severity Scale (LSSS) 2.0, Wechsler Adult Intelligence Scale‐Revised (WAIS‐R), and Wechsler Memory Scale‐Revised (WMS‐R). Quality of life (QOL) was evaluated using the 36‐item Short Form Health Survey (SF‐36).
Results. Of the 12 patients, five (42%) were assessed as Engel Class I during 12–62 months of follow‐up. LSSS scores declined sharply compared with the baseline of patients not in the seizure‐free category. Functions of memory and intelligence declined transiently without statistical significance (p>0.05) immediately after surgery, but improved significantly (p<0.05) six months later. The qualities of life improved except vitality.
Conclusion. Bilateral transfrontal minimal RFTC of the amygdalohippocampal complex may terminate seizures or reduce seizure severity in patients with BMTLE. Under limited coagulations, neuropsychological function was not affected but improved along with seizure control.
We aimed to validate three IgAN risk models proposed by an international collaborative study and another CKD risk model generated by an extended CKD cohort with our multicenter Chinese IgAN cohort. Biopsy-proven IgAN patients with an eGFR ≥15 ml/min/1.73 m2 at baseline and a minimum follow-up of 6 months were enrolled. The primary outcomes were a composite outcome (50% decline in eGFR or ESRD) and ESRD. The performance of those models was assessed using discrimination, calibration, and reclassification. A total of 2,300 eligible cases were enrolled. Of them, 288 (12.5%) patients reached composite outcome and 214 (9.3%) patients reached ESRD during a median follow-up period of 30 months. Using the composite outcome for analysis, the Clinical, Limited, Full, and CKD models had relatively good performance with similar C statistics (0.81, 0.81, 0.82, and 0.82, respectively). While using ESRD as the end point, the four prediction models had better performance (all C statistics > 0.9). Furthermore, subgroup analysis showed that the models containing clinical and pathological variables (Full model and Limited model) had better discriminatory abilities than the models including only clinical indicators (Clinical model and CKD model) in low-risk patients characterized by higher baseline eGFR (≥60 ml/min/1.73 m2). In conclusion, we validated recently reported IgAN and CKD risk models in our Chinese IgAN cohort. Compared to pure clinical models, adding pathological variables will increase performance in predicting ESRD in low-risk IgAN patients with baseline eGFR ≥60 ml/min/1.73 m2.
