Objective To explore the clinical and electroencephalographic characteristics of frontal lobe ep- ilepsy(FLE).Methods The clinical and electroencephalographic data of 80 patients with FLE were analyzed.Re- suits The seizure types of frontal lobe epilepsy were simple focal seizure-complex focal seizure and secondary gen- eral tonic.clonic seizure.Seizures were often exhibited in relatively short duration,hyper motor,tonic or postural.Fre- quent nocturnal attacks and slight postictal mental confusion was increased.Interictal EEG manifested sharps or spikes or slow wave in the frontal area.Ictal EEG showed paroxysm rhythms.Conclusion FLE is a distinct epilepsy syndrome.

Objective This research summarized the nursing experience of critically ill patients infected by H7N9 avian influenza who were treated with extracorporeal membrane oxygenation (ECMO) and artificial liver device.Methods 10 critically ill patients infected by H7N9 avian influenza were selected,during treatment of ECMO combined with artificial liver device,nursing care such as careful observation of the changes of symptoms,strict disinfection and protection,contact isolation,symptomatic treatment to fever,correct management of airway and ventilator circle,pipeline nursing of ECMO and artificial liver device,mental nursing,symptomatic and support therapy which included antivirus,anti-hypoxia and anti multiple organ failure,anti-shock,anti-infection,microecological balance maintenance and water-electrolyte balance maintenance.Results 4 critically ill patients infected by H7N9 avian influenza improved and removed ECMO and artificial liver device,among whom one patient rehabilitated and was discharged.Another 6 patients were in a steady state.Conclusions For critically ill patients infected by H7N9 avian influenza,comprehensive and elaborate care can facilitate early recovery of patients.

Objective To summarize the clinical characteristics of Foix-Chavany-Marie syndrome.Methods The clinical,electroencephalography and imaging characteristics,as well as etiology,treatment and prognosis of 4 cases of Foix-Chavany-Marie syndrome were retrospectively evaluated,and relevant literature was reviewed to investigate its pathogenesis.Results All the 4 cases presented with hypersalivation,facial diplegia,dysarthria and dysphagia with autonomic-voluntary dissociation.Brain MRI showed bilateral cortical or subcortical lesions in the opercula and perisylvian areas.Three cases were secondary to encephalitis,and 1 case was related to perinatal hypoxic-ischemic encephalopathy.After administration of antiepileptic drugs,they were free of seizures.But all the other symptoms remained.Conclusions Autonomic-voluntary dissociation is a feature of Foix-Chavany-Marie syndrome.Most patients are due to bilateral structural or functional lesions between motor cortices and brain-stem cranial motor nuclei.The prognosis depends on the heterogeneous etiologies,such as encephalitis and cerebrovascular disease.

Objective To observe the results of multifocal visual evoked potential (mfVEP) examination in patients with anterior ischemic optic neuropathy (AION) before and ater treatment,and to probe its clinical significance.Methods A total of 90 patients (90 eyes) with AION were examined by mfVEP;the second-order reaction of mfVEP was analyzed.The reaction was divided into upper and lower hemi-field of visual field,or 1 / 4 quadrant visual field (superior nasal,inferior nasal,superior temporal,and inferior temporal).The sum of waves of each response was analyzed and the results in various regions were compared.The features of wave configuration was compared between the AION eyes and the contralateral eye,and between the AION eyes before and after treatment.Results The amplitude and latency of P-wave of mfVEP was 0.198±0.033 and 100.197±7.354 respectively in AION eyes before treatment,and was 0.271±0.024 and 98.567±6.794 in the contralateral eyes;the difference was significant (t=16.556,18.330;P＜0.01).The amplitude and latency of P-wave of mfVEP was 0.229±0.016 and 100.104±10.603 respectively in AION eyes after treatment,which differed much from that before the treatment (t=13.649,8.858;P＜0.01) and also from that of the contralateral eyes (t=13.649,8.858;P＜0.01).Conclusions The amplitude and latency of P-wave of mfVEP may accurately reflect the recovery of local optic nerve damage in AION eyes before and after treatment with good repeatability.AION can be used as a new method for AION diagnosis and detection of the prognosis.

Objective To investigate the clinical characteristics,treatment and prognosis of senile epilepsy. Methods The clinical characteristics of 180 elderly patients with epilepsy were retrospectively studied. Results The common causes of senile epilepsy were cerebrovascular disease (8 cases,4.4％),brain tumor(24 cases,13.3％),brain trauma and operation (18 cases,10.0％),brain atrophy (6 cases,3.3 ％ ),The most type of seizures were focal seizures (106 cases,58.9 ％) or focal seizures preceding a generalized (62 cases,34.4％). Electroencephalogram (EEG) usually showed focal slow wave activity or rhythm.Most of seizures were responsive well to single antiepilepsy drug. Conclusions The causes of elderly epilepsy are cerebrovascular disease,brain tumor,brain trauma, brain operation, brain atrophy. Senile epilepsy is more likely to have symptomatic and focal seizures,and can be controlled by anti-epilepsy drugs.

Objective To analyse clinical characteristics of patients with epilepsy induced by playing Mah-jong.Methods The medical records of 14 epileptic patients who were admitted at the Epilepsy Center of PUMC Hospital chief complaint of Mah-jong induced epileptic seizures from 1996 to 2000 were retrospectively reviewed.Results 12 patients showed generalized tonic-clonic seizures and 2 patients showed partial seizures with secondary generalization. Interictally, normal EEG were found in 13 patients, and one patient was discharged. None patients recept anticonvulsant therapy for preventing seizures. Conclusion Mah-jong induced epilepsy, a reflex epilepsy, is probably related to thinking,spatial task and decision making while playing mah-jong. It is benign, and could be easily prevented by stopping playing Mah-jong.

Objective To analyze clinical characteristics of patients with juvenile myoclonic epilepsy in China. Methods Eighty-seven patients were retrospectively studied in the aspects of family history, febrile seizures, clinical features, EEG, treatment effect. Results There was a female preponderance of incidence. In contrast to the earlier studies we found a high incidence of febrile seizures and a low incidence of family history. myoclonic seizures began at age of ( 13.1?3.4) years. That combined with generalized tonoclonic seizures began at age (14.3?3.8) years. Absence seizures began at age (10.0?3.3) years. The correct diagnosis was delayed at a mean of 2.2 years from onset of the disease. The incidence of abnormal EEG discharge could be enhanced by hyperventilation, photic stimulation and sleep. Sixteen patients who had received carbamazepine or phenytoin were experienced aggravation of seizures. Forty-five patients who received monotherapy with sodium valproate remained seizure-free in a follow-up longer than 0.5 years. Conclusions Failure to recognize JME may result in uncontrolled seizures, and even aggravated of seizures by using antiepilepsy drugs. Effective treatment was achieved with small doses of sodium valproate.

Objective To investigate clinical features and the pathophysiology of 43 children with atypical idiopathic partial epilepsies of childhood(IPEC)that is unclassified according to the International League Against Epilepsy classification.Methods All the children with partial epilepsy of childhood in out hospital were followed up,including those age-related cases with benign process and excluding those with benign epilepsy of childhood with centro-temporal EEG foci,Panayiotopoulos type and Gastaut type.We reviewed their EEGs,seizures and therapeutic data to analyze the semiologieal characters and the interietal activities during they were awake and sleeping.Results The average age of onset of epilepsy was 8.84years old.Frontal absences(43.2%),adversive seizures(47.7%)were more common.Everyday seizures occurred in 38.6%of patients and monthly seizures in 56.8%of patients.Atypical focal(43.2%),multifocal(27.3%),and generalized spike and waves(29.5%),were more predominant in frontal location when they were awake.During sleep,sharp waves generalized or the amplitude increased.At the last follow-up,88.6%of patients were in complete clinical remission and EEG in 22.7%of cases was normal.Among them 2 patients had stopped taking antiepileptic drugs(AEDs)and 6 patients were reducing the doses of AEDs.EEG Was abnormal only in sleep or decreased synchronization.The patients were more responsive to earbamazepine combined with sodium valproate(P<0.01).Conclusion Special partial epileptic syndrome is age-related,having excellent prognosis,which might origin from the frontal lobe.
