ABSTRACT
In this first study comparing epilepsy-specific quality-of-life measures of children after epilepsy surgery (2.4 years after focal resection) with those of a matched comparison group of nonoperated patients, seizure severity, medication side effects, overall quality of life, general health, physical activity, and well-being were better in surgical patients (70.6% seizure free vs 8.3%). Cognitive, social, and behavioral functioning did not differ, suggesting that these may require additional interventions during postsurgical follow-up.

OBJECTIVE: To identify risk factors for subclinical hypothyroidism (SCH) (thyroid-stimulating hormone levels >5 mIU/mL) in patients receiving valproate (VPA) therapy. STUDY DESIGN: During a period of 2 years, consecutive patients with epilepsy receiving VPA and a control group of patients with diseases other than epilepsy attending a tertiary care neurology clinic were screened for SCH. The 2 groups were compared. The association between SCH and specific risk factors was investigated with bivariate and multivariate analyses. RESULTS: Thirty-six of 143 patients receiving VPA (25.2%, mean age +/- SD: 8.5 +/- 6.6 years) and none of the 35 control subjects had SCH (P < .001). Predictors of SCH were younger age (OR: 1.15, cutoff age 3.9 years); duration of treatment between 6 and 24 months versus <6 months (OR: 2.98) and >24 months (OR: 2.66); VPA polytherapy with enzyme-inducing agents (OR: 6.08), or polytherapy with non-enzyme-inducing agents (OR: 3.34) compared with VPA monotherapy. Most (88.2%) patients with duration of therapy >2 years were older than 3.9 years. CONCLUSION: Risk factors for SCH were young age, co-medication with antiepileptic drugs, and duration of therapy between 6 and 24 months. Screening patients with these risk factors may be warranted.

OBJECTIVE: To investigate the effects of two doses of vitamin D given over 1 year on bone density in ambulatory patients on long-term antiepileptic drug (AED) therapy. METHODS: We conducted two parallel, randomized, controlled trials in 72 adults (18 to 54 years old) and 78 children and adolescents (10 to 18 years) on long-term AED therapy. They received either low-dose vitamin D 400 IU/day or high-dose vitamin D 4,000 IU/day (adults) and 2,000 IU/day (children/adolescents). Bone mineral density (BMD) was measured using dual-energy x-ray absorptiometry. RESULTS: In adults, baseline BMD was lower than that of age- and gender-matched controls vs either a Western or an ethnically identical population. After 1 year, there were significant increases in BMD at all skeletal sites compared to baseline in the high-, but not in the low-dose treatment group. However, BMD at 1 year remained below normal. In children, baseline BMD was normal vs age- and gender-matched controls and showed significant and comparable increases in both treatment groups. CONCLUSIONS: In ambulatory adults on antiepileptic drugs, high-dose vitamin D therapy substantially increased bone mineral density at several skeletal sites. In children, both doses resulted in comparable increases in bone mass.
