Recent studies suggest that the risk of cerebral infarction is increased during the puerperium but not during pregnancy itself. Most of the known causes of ischaemic stroke in the young have been reported during pregnancy. In most of these conditions, it is uncertain whether pregnancy is coincidental or plays a role in the occurrence of stroke. ⋯ Pregnancy and in particular the puerperium seem to be associated with an increased risk of intracerebral haemorrhage. The most common causes are eclampsia and ruptured vascular malformations. Whether pregnancy increases the risk of rupture of an arteriovenous malformation is controversial.

The value of conventional transcranial Doppler ultrasound in the diagnosis and monitoring of cerebral vein thrombosis is unclear. Previous studies have suggested the usefulness of this method in two cases with superior sagittal sinus thrombosis that showed increased velocities of deep cerebral veins. The purpose of the present study was to evaluate the deep intracranial venous circulation in patients with that pathology. ⋯ One patient showed slightly increased velocities in the BVR, and the other two showed normal venous velocity values. This study confirms the usefulness of conventional transcranial Doppler ultrasound in detecting superior sagittal sinus thrombosis. However, a normal examination does not exclude this diagnosis.

Neuroborreliosis, a manifestation of infection with the spirochete Borellia burgdorferi, has become the most frequently recognised arthropod-borne infection of the nervous system in Europe and the USA. The best criterion of an early infection with B. burgdorferi is erythema migrans (EM), but this is present in only about 40-60% of patients with validated borreliosis. Therefore use of the duration of the disease as a classification criterion for neuroborreliosis is increasing, the chronic form being distinguished from the acute when symptoms persist for more than 6 months. ⋯ Penicillin G 20 mega units/day and doxycycline 200 mg/day may be suitable for uncomplicated meningopolyneuritis, without involvement of the central nervous system. The durationof treatment--at least 2 weeks in the acute forms and 3 weeks in the chronic forms of neuroborreliosis--is very important for successful treatment. Corticosteroids are recommended only for patients with severe pain that does not respond to antibiotics an analgesics.

In 32 subjects without signs or symptoms of peripheral nerve disorder, sensory nerve action potentials (SNAPs), elicited by stimulation at the wrist, were recorded from the fingers of both hands with ring electrodes. Recordings from the volar proper digital nerves confirmed the standard distribution of the median and ulnar cutaneous innervation. ⋯ Furthermore, we found that the dorsal aspect of the proximal part of the ring finger is mainly supplied by the DCUN. These findings differ from the standard cutaneous innervation pattern as depicted in neurological textbooks, but they are in agreement with earlier anatomical studies.

Review Case ReportsPalliative therapy in the terminal stage of neurological disease.
As recently pointed out by the American Academy of Neurology, providing adequate palliative care to dying patients is the duty of every neurologist. Because of a lack of relevant articles in the neurological literature, we have compiled current treatment recommendations for the most important symptoms arising in the endstage of neurological diseases. ⋯ A discussion of difficult decisions is included, e.g., the appropriate extent of fluid substitution or the ethical implications of sedation in the terminal phase. It is hoped that this compilation may provide a basis for future research in palliative therapy in neurology.
