[Seizures in pregnancy: not always eclamptic seizures].

Background: The differential diagnosis of seizures during pregnancy is extensive and includes potentially fatal underlying diagnoses. Both pregnancy and non-pregnancy related aetiologies should be considered.

Case Description: A 38-years old pregnant woman presented to the emergency department at 31 weeks and 5 days with generalized tonic-clonic seizures.

[Orthostatic tremor: unsteadiness while standing still].

We present three patients with histories of the typical unsteady feeling in the legs while standing still which disappears when walking or sitting down. An orthostatic tremor is a disorder that is difficult to recognise because patients describe balance disturbances rather than tremors. Clinical findings include a fine tremor in the legs which may be invisible but can be heard on auscultation and felt on palpation of the leg muscles.

Chronic daily headache in children and adolescents.

Objective: To describe the clinical features of children with chronic daily headache (CDH) and examine the usefulness of the International Classification of Headache Disorders-II.

Background: Few data are available on chronic daily headache and analgesic overuse in children and adolescents and there are no specific criteria for headache in children.

Methods: We retrospectively reviewed all charts of 79 children and adolescents (<16 years) with headache on > or =15 days/month presenting to the outpatient clinic of the Department of Neurology of the Leiden University Medical Center between 1994 and 2001.
