[Monitoring of intracranial pressure].

A very small fiberoptic catheter initially developed as an intravascular pressure sensor was incorporated into a system to be used as an intracranial pressure (ICP) monitor. 13 patients with intracranial hypertension have been studied with this probe. The clinical experience confirmed the safety, accuracy and reliability of the device. The monitor has functioned very well, and there have been no complications except for two breakages of optic fiber as a result of nursing manoeuvres. This new device can be placed into the ventricular, subdural and epidural space. Camino System appears to offer advantages over other monitors presently in use.

Investigation on cerebrospinal fluid opioids and neurotransmitters related to spinal cord stimulation.

The purpose of this study was to assess the biochemical mechanisms underlying spinal cord stimulation (SCS). Seventeen patients with chronic pain were investigated by measuring cerebrospinal fluid concentrations of endogenous opioids and biogenic amines before and during dorsal column stimulation. Basal cerebrospinal fluid beta-endorphin levels were below the normal range. No significant change of norepinephrine, epinephrine, dopamine, beta-endorphin, beta-lipotropin, or adrenocorticotropic hormone levels were found after SCS. A 50% increase of cerebrospinal beta-endorphin and beta-lipotropin levels occurred in 6 out of 16 patients, namely those where SCS gave the major pain relief. These data confirm the derangement of the endogenous opioid system in chronic pain conditions and suggest that the beta-endorphin response to SCS could have clinical value in predicting the success of treatment.

Paretic neurosyphilis and cerebral gumma. Case report.

A rare case of neurosyphilis presenting with dementia paralytica and radiological appearance of cerebral gumma is reported. In accordance with previous comparable reports Authors noticed that diagnosis of this disease actually is still based on serological tests and clinical examination. CT, NMR and Cerebral angiography were not able to provide diagnostic findings, although NMR confirmed its ability to detect lesions not discovered by CT scan. Also findings from stereotactic biopsy only revealed an old not active infection.

Ossifying parasellar chondroma. Case report.

The Authors report a case of cartilaginous tumor of the parasellar region, diagnosed as ossifying chondroma by virtue of the intense calcification it presented. Preoperative diagnosis was suggested by CT, which showed a characteristic honeycomb conformation, with alternate areas of greater or lesser density, without contrast enhancement. Angiography is, however, essential in planning the operation, which must on occasion be confined to partial resection only. This limitation may be acceptable where functionally important areas are concerned, since these neoplasms show an apparent tendency to only modest growth.
