[Treatment of trigeminal neuralgia: an update and future prospects of percutaneous techniques].

Introduction: Trigeminal neuralgia is one of the most severe facial pain syndromes. The annual incidence varies between 4-13% and has a significant effect on patients' quality of life. When the pain cannot be controlled by pharmacological treatment, several different surgical options can be considered.

Continuous cerebral PtO2 measurements in awake patients as a diagnostic tool in suspected chronic adult hydrocephalus--a retrospective study of 10 cases.

Background: During the last decade of the 20th century, continuous invasive PtO(2) recording has become a widely accepted and well-established means of monitoring patients with acute traumatic or spontaneous cerebral lesions. It is considered a safe and reliable tool for the detection of hypoxia in the ICU setting. However, while invasive measurements of intracranial pressure are being used both in the ICU and in standard diagnostic protocols for suspected chronic adult hydrocephalus the same has not yet happened in relation to PtO(2) recordings.

Anton's syndrome due to a giant anterior fossa meningioma. The problem of routine use of advanced diagnostic imaging in psychiatric care.

We present a case of blindness and Anton's syndrome in a psychiatric patient with late diagnosis of a giant frontal meningioma. The criteria for advanced diagnostic imaging in the psychiatric population are discussed. We conclude that MR or CT scan is indicated in psychiatric in-patients who fail to improve with standard psychiatric treatment.
