SUMMARY Subjective sleep quality and its related factors were investigated in 869 (530 F, 339 M) 17-year-old adolescents, who were selected from the pupils of state-run secondary schools in the city of Pavia in the north west of Italy. The study was conducted cross sectionally, and it consisted of a questionnaire based survey. One hundred and fortytwo subjects (16.5% of the whole sample, 19% of the females and 11.7% of the males) met the criteria chosen for definition as poor sleepers (namely, a complaint of 'non restorative nocturnal sleep', 'often' or 'always' over the previous 12 mo). A significant association was found between chronic poor sleep and (1) gender (female) (2) emotional factors, such as worries, anxiety and depression (3) poor sleep hygiene (4) arousal related parasomnia. Only 4% of poor sleepers took sleep promoting drugs (including benzodiazepines, homeopathic products and other medications), generally without seeking medical advice. adolescence, poor sleep INTRODUCTION schools in the city of Pavia, which is a medium sized city of 80000 inhabitants in the north west of Italy.

The majority of patients with epilepsy maintain seizure control during pregnancy. The apparently higher risk of seizures among women treated with oxcarbazepine and the more frequent increases in drug load in the oxcarbazepine and lamotrigine cohorts prompts further studies on relationships with pharmacokinetic changes. Risks associated with status epilepticus appear to be lower than previously reported.

The kinetics of oxcarbazepine (OXC) and its active metabolite 10-hydroxy-carbazepine (10-OH-CZ) after a single oral OXC dose (600 mg) were compared in healthy control subjects and in epileptic patients treated with phenobarbitone or sodium valproate (n = 8 in each group). In all groups, serum 10-OH-CZ concentrations were much higher than those of the parent drug. In patients on valproate, the kinetics of OXC and 10-OH-CZ did not differ significantly from those observed in controls. In patients on phenobarbitone, AUC values of both OXC and 10-OH-CZ were lower than in controls (2.9 ± 0.4 vs 5.1 ± 0.7 ,ug ml-' h and 89 ± 7 vs 119 ± 10 ,ug ml-' h respectively, means ± s.e. mean, P < 0.05), whereas 10-OH-CZ half-lives were only marginally shorter (17 ± 1 h vs 20 + 2 h, NS). These data indicate that the biotransformation of OXC and 10-OH-CZ may be accelerated by concomitant treatment with phenobarbitone but that the magnitude of this effect is unlikely to be of great clinical significance.

1. The single dose pharmacokinetics of orally administered nimodipine (60 mg) were investigated in normal subjects and in two groups of epileptic patients receiving chronic treatment with hepatic microsomal enzyme‐inducing anticonvulsants (carbamazepine, phenobarbitone or phenytoin) and sodium valproate, respectively. 2. Compared with the values found in the control group, mean areas under the plasma nimodipine concentration curve were lowered by about seven‐fold (P less than 0.01) in patients taking enzyme‐inducing anticonvulsants and increased by about 50% (P less than 0.05) in patients taking sodium valproate. 3. Nimodipine half‐lives were shorter in enzyme‐induced patients than in controls (3.9 +/‐ 2.0 h vs 9.1 +/‐ 3.4 h, means +/‐ s.d., P less than 0.01), but this difference could be artifactual since in the patients drug concentrations declined rapidly below the limit of assay, thus preventing identification of a possible slower terminal phase. In valproate‐treated patients, half‐lives (8.2 +/‐ 1.8 h) were similar to those found in controls.

To assess frequency, types, and mechanisms of comorbidities in people with epilepsy and verify their association with disease features and outcome. Methods: This cohort study was performed in 13 Italian epilepsy centers with nationwide distribution and accurate records. Eligible patients were children and adults diagnosed before December 31, 2005, and followed for a minimum of 10 years. Two pairs of raters independently reviewed patients' records and classified each comorbidity. In case of disagreement, a third reviewer made the final decision. Comorbidities were classified according to type (organ/system) and underlying mechanism (causal, shared risk factors, chance association). Comorbidity types and mechanisms were described in the entire sample and according to epilepsy prognostic patterns (sustained remission, relapsing-remitting course, no remission). Results: Of 1006 included patients, 266 (26.4%) had at least one comorbidity. The most common were developmental/perinatal (7.5% of cases), psychiatric (6.2%), cardiovascular (5.3%), and endocrine/metabolic (3.8%). Among 408 reported comorbidities, the underlying mechanisms were, in decreasing order, chance association (42.2%), shared risk factors (31.1%), and causal (26.7%). Psychiatric diseases were present in 13.3% of patients with no remission, 5.9% of patients with relapsingremitting course, and 4.8% of patients with sustained remission (p = .016). The corresponding numbers for endocrine/metabolic diseases were respectively, 9.6%, 3.4%, and 2.9% (p = .013); for respiratory diseases were 3.6%, .3%, and .3% (p = .001), and for urogenital diseases were 3.6%, .7%, and 1.6% (p = .048). The association of endocrine/metabolic, psychiatric, and respiratory comorbidities with epilepsy prognosis was confirmed by multivariable analysis adjusted for the main demographic and

Four of five members of a family complained of repeated attacks of hemiplegic migraine, migraine with aura of different types, or migraine without aura. The hemiplegia always outlasted the headache and was often accompanied by altered consciousness, aphasia, and, in one patient, coma; in this latter patient, the ictal EEG, recorded during two attacks, showed delta activity in the hemisphere contralateral to the hemiplegia. At least 2 months after their latest attacks, three patients showed dyscalculia, attentional disturbances, and impaired long-term verbal memory on neuropsychologic assessment. There were no cognitive disturbances in the unaffected relative. The severity of cognitive impairment appears to be correlated with migraine history. We attempt to classify these cases according to the criteria of the International Headache Society.

Summary:Purpose: To investigate the risk of illnesses in a cohort of patients with epilepsy and in matched nonepilepsy controls, by type and complications.Methods: A total of 951 children and adults with idiopathic, cryptogenic, or remote symptomatic epilepsy and 904 matched controls seen in secondary and tertiary centers in eight European countries (England, Estonia, Germany, Italy, the Netherlands, Portugal, Russia, Slovenia) were followed prospectively for 17,484 and 17,206 person-months and asked to report any spontaneous complaint requiring medical attention (illness), its type and complications (hospitalization, absence from work or school, medical action). Risk assessment was done by actuarial methods, relative risks (RR), and 95% confidence intervals (CIs).Results: During the study period 644 patients (68%) and 504 controls (56%) reported an illness (p < 0.0001); 30% were seizure related. The cumulative probability of illness at 12 and 24 months was 49 and 86% in the cases and 39 and 75% in the controls (p < 0.0001). The largest differences regarded disorders affecting the nervous system (NS) (RR, 3.3; 95% CI, 2.3-4.2) and ear, nose, and throat (ENT) (RR, 1.3; 95% CI, 1.0-1.6). In patients with epilepsy, an NS illness was more likely to be followed by hospital admission, work absence, or medical intervention. All risks were significantly reduced after excluding seizure-related events.Conclusions: Patients with epilepsy are at higher risk of NS and ENT illnesses and complications than the general population. However, the risk of illness is significantly reduced when seizure-related events are excluded. Key Words: EpilepsyMorbidity-Illnesses.Patients with epilepsy have been thought to have a higher risk of illness than the general population, but comorbidity in epilepsy has been investigated in few population-based prevalence or analytic studies. Other clinical conditions and disabilities were reported by 47% of adults with epilepsy in Sweden, with psychiatric, cardiovascular, pulmonary, systemic, and renal diseases in decreasing order (1). Lifetime mental and gastric disorders were reported by 7 and 3% of adults with childhoodonset epilepsy in the Czech Republic (2). In Finland, somatic comorbidity was found in 84-95% of patients with childhood-onset epilepsy and 67-74% of controls (3). In a multicenter European cohort study of children and adults with idiopathic, cryptogenic, or remote symptomatic epilepsy, we found one or more illnesses at entry in 30% of cases compared with 17% of age-and sex-matched controls (4).These contrasting results may be explained by differences in the study populations and in the study design and methods. In addition, the morbidity risk attributable Accepted September 14, 2003. Address correspondence and reprint requests to Dr. E.
