[EX Q]: Migraine is associated with epilepsy, but the time order and nature of the relationship are unclear. We conducted a population based case control study to clarify the time order to determine whether migraine is a risk factor for epilepsy.', 'Migraine symptoms were evaluated in a population-based case-control study of all incident epilepsy in Icelandic children and in matched controls (next two same sex births in the country).', 'Migraine was associated with a fourfold increased risk for developing epilepsy, an association explained by migraine with aura (odds ratio, 8.1; 95% confidence interval, 2.7-24.3). Migraine without aura did not increase risk for epilepsy.

[EX Q]: To investigate the relationship between the damages of hand functions and the type of cerebral palsy (CP) in children with CP.', 'A total of 280 children aged 4-12 years old with CP in the 20 districts of Chengdu were included. The damages of hand functions were assessed with the Chinese Version of Manual Ability Classification System (MACS) and its relationship with the type of CP were analyzed.', 'Among the 280 investigated children, there were 195 chidren with spastic CP, which accounted for the largest proportion (69.64%), wherein the spastic diplegia was most common (56.41%). The classification of MACS was level I-II in 65.13% children with spastic CP, whereas the classification of MACS was level IU-V in 84. 44% and 80.95% children with mixed and dyskinetic CP, respectively. With the increase of the degree of cognitive dysfunction in children with CP, the level of MACS was also increased. There was a difference between the classification of MACS and the different type of CP (P<0.05). The children with spastic CP were mostly mild hand dysfunction, while the children with mixed and dyskinetic type of CP were mostly middle and severe hand dysfunction. A positive correlation was found between the MACS and the subtype of spastic CP (r=0.541, P<0.05). In most of the children with diplegia from spastic CP, the hand dysfunction was mild, whereas the children with quadriplegia from spastic CP were mostly middle and severe hand dysfunction.

[EX Q]: Clinical trials of adjuvant radiotherapy after mastectomy have largely excluded women aged 70 years or over, even though they comprise 30% of the breast cancer population. This study examined outcomes in elderly women with high-risk breast cancer treated with or without postmastectomy radiotherapy (PMRT).', 'Data were analysed for 233 women aged 70 years or over with high-risk breast cancer (tumours > 5 cm or > or = 4 positive axillary nodes) treated with mastectomy and referred to the British Columbia Cancer Agency from 1989 to 1997. Tumour and treatment characteristics were compared between two cohorts: women treated with PMRT (n = 147) vs women treated without PMRT (n = 86). Univariate and multivariate analyses of 10-year Kaplan-Meier locoregional recurrence (LRR), distant recurrence, breast cancer-specific survival and overall survival were carried out.', 'Median follow-up time was 5.5 years. The distribution of tumour sizes was similar in the two groups. Compared with women treated without PMRT, higher proportions of women who underwent PMRT had four or more positive nodes (83% vs 67%, P = 0.01) and positive surgical margins (14% vs 4%, P = 0.02). Systemic therapy, used in 94% of women, was comparable in the two cohorts (P = 0.63). Elderly women treated with PMRT had significantly lower LRR compared with women treated without PMRT (16% vs 28%, P = 0.03). No differences in distant recurrence, breast cancer-specific survival or overall survival were observed in the two treatment groups (all P > 0.05). On multivariate analysis, the omission of PMRT and the presence of high-grade histology were significant predictors of LRR, whereas an increasing number of positive nodes was significantly associated with distant recurrence and overall survival.
