Objective To explore the effect and adverse reaction of topiramate(TPM) on treating Lennox-Gastaut syndrome(LGS)(including therapeutic alliance or single ). Methods Twenty-four cases with LGS whose attacks could not be controlled by re-(gular) therapy were selected.TPM was gradually increased from low dosage till its showing effect or untolerant adverse reaction.Results Two cases were excluded because of adverse reaction and increase of attacks. The remained cases were followed up from 6 months to 15 months (average: 9 months). The total effective rate was 82.6%, 11 cases accounting for 45.8% free of attack. The tonic-clonic seizure reduced more than 50% accounting for 82.2%, the full control accounting for 66.7%. The myoclonic seizure reduced more than 50% accounting for 81.8%,the full control accounting for 58.8%.The atypical absence seizure reduced more than 50% accounting for 81.8%, the full control accounting for 63.6%. The maximum effect occurred about 2-40 weeks following TPM used, the dosage about 2-10 mg/(kg?d).The adverse reaction included anorexia (8 cases), language disorder (5 cases), drowsiness (4 cases), decrease of anamnesis (3 cases), weight loss or unchanged(3 cases), inattention (3 cases), depression (3 cases), mental bradypraxia (2 cases ), skin damage (1 case), stupor (1 case), gross hematuria(1 case).The hepatic and renal function were normal during therapy. Conclusion TPM is a new, broad-spectrum, effective and safe antiepileptics drug on treating LGS.

Objective To evaluate the correlation between the degree of cochlea endolymphatic hydrops(EH) and hearing loss and symptoms in patients with unilateral Meniere's disease. Methods Fifty seven patients with unilateral Meniere's patients were retrospectively quantitatively analyzed, which evaluated the correlation between the cochlea EH and hearing loss and symptoms. The affected ears in the experimental group(57 ears) and the asymptomatic ears in the control group(57 ears), were confirmed by bilateral intratympanic Gd-DTPA injection and 3D real IR MRI scan after 24 h. The maximum length of endolymph space and labyrinth chamber along the modiolus cochleae and their ratio which represented the endolymph space proportion of each turn(R1, the basal turn;R2, the middle turn;R3, the apical turn) were calculated. And the paired t test was used to compare the differences in EH degree between the experimental and control group;Pearson correlation analysis was used to analyze the correlation between the cochlea EH degree and hearing loss and duration of symptoms. Results R1, R1 and R3 of ipsilateral cochlea were higher than normal cochlea(ipsilateral R1:0.354±0.097 vs. normal R1:0.185±0.031, P<0.01;ipsilateral R2:0.445 ± 0.098 vs. normal R2:0.201 ± 0.046, P<0.01;ipsilateral R3:0.467 ± 0.102 vs. normal R3:0.221 ± 0.053, P<0.01). A positive correlation was found between the degree of EH in each turn and high-frequency hearing loss(r=0.275, 0.281, 0.329, respectively;all P<0.05), whereas no correlation was found between the extent of EH and the time of vertigo, tinnitus and hearing loss(P>0.05). In addition, there was a correlation between the degree of EH in the apical turn and low, medium, high-frequency hearing loss(r=0.271, 0.269, 0.329, respectively; all P<0.05). Conclusions The degree of cochlea EH in the basal and second turn showed great relevance with the high-frequency hearing loss, and the apical turn EH degree was relevant with the low, medium, high-frequency hearing loss, but there was no correlation between the EH degree of each turn, ages and symptoms.
