History of surgery for temporal lobe epilepsy.

The history of epilepsy and its treatment goes back to ancient times when it included medicinal herbs, lifestyle modifications, and even surgery. Trepanation is considered the oldest surgical procedure for the treatment of epilepsy. The first series of temporal lobectomies for the treatment of drug-resistant epilepsy were reported by Penfield and Flanigin (1950). During the years since then, neuroimaging and other technologies have had remarkable and revolutionary progress. This progress has resulted in tremendous advancements in understanding the underlying causes and pathophysiology of epilepsies. With the help of these technologies and advancements, we may now offer surgery as a safer therapeutic option to more patients who are suffering from drug-resistant temporal lobe epilepsy. However, the degree of improvement in surgery outcome has not been proportionate to the technological progress.

Factors associated with tonic-clonic seizures in patients with drug-resistant mesial temporal epilepsy.

PURPOSE: Among different seizure types, tonic-clonic seizures are more significant because they are more often associated with morbidity. No prior study has been done to investigate risk factors associated with tonic-clonic seizures in patients with mesial temporal epilepsy. METHODS: In this retrospective study, all drug-resistant mesial temporal epilepsy patients in the database of patients who underwent epilepsy surgery at Jefferson comprehensive epilepsy center were recruited. These patients were prospectively registered in a database from 1986 till 2014. Patients' age, gender, epilepsy risk factors, age at seizure onset, and preoperative seizure type(s) were registered routinely. Potential risk factors associated with experiencing preoperative tonic-clonic seizures were investigated. RESULTS: Two hundred seventy-five patients (132 males and 143 females) were studied. Aura type was associated with experiencing perioperative tonic-clonic seizures. Patients with epigastric auras less frequently reported having tonic-clonic seizures compared with those who had other types of auras (odds ratio: 0.37 and 95% confidence interval: 0.19-0.70; p=0.001) and those who did not have any auras (odds ratio: 0.35 and 95% confidence interval: 0.16-0.77; p=0.008). CONCLUSION: Epigastric auras may indicate that a specific anatomic location is involved in epileptogenesis from which generalization is harder because of that location's poor connections with other brain regions.

Worksite physical activity interventions and obesity: a review of European studies (the HOPE project).

OBJECTIVE: Our aim was to review the effectiveness of physical activity promotion interventions in the worksite setting in Europe in order to identify those studies that had measured obesity-related outcomes and to evaluate how external validity of the findings had been assessed. METHODS: We conducted a review of studies conducted in Europe, published up to December 2009. We assessed levels of evidence regarding effectiveness and analysed external validity using the RE-AIM framework. RESULTS: Studies included (n = 33) were divided in 6 intervention categories. Moderate evidence of effectiveness was found for physical fitness outcomes with exercise training interventions and for physical activity outcomes with active commuting interventions. There was no or inconclusive evidence for obesity-related outcomes for all intervention categories. For external validity, elements receiving the least attention (<20%) were representativeness of participants, setting-level inclusion/exclusion criteria and representativeness, characteristics regarding intervention staff, implementation of intervention, costs, long-term effects and programme sustainability. CONCLUSIONS: Active commuting and exercise training appear as promising approaches to promote physical activity or fitness in the workplace. The effect of interventions on obesity-related outcomes remains to be further investigated. There is a need to better report elements of generalizability and dissemination for translation into practice of worksite physical activity interventions.
