Brain-stem auditory evoked potentials in supratentorial brain tumors.

A group of 42 adult patients with supratentorial brain tumors were studied with computed tomography (CT or/and NMR) and brain-stem evoked potentials (BAEPs). 12 patients had meningiomas and 30 had malignant tumors (gliomas and metastases). The latencies of wave V and of the interpeak latency I-III, III-V and I-V were evaluated both on the lesion side and the opposite side. In meningiomas mean latencies did not show significant differences from normal, while mean latencies in malignant tumors were significantly prolonged, except for the I-III interpeak latency. The results of this study demonstrate that BAEPs may be altered by supratentorial brain tumors. This examination appears to be useful in the monitoring of these lesions after treatment.

The VEP in evaluation of pituitary tumors.

12 patients with pituitary tumors were studied with VEP, to demonstrate involvement of the optic chiasma. In 3 patients VEP was recorded pre- and post-surgery to evaluate a modification in the shape and latencies of the potentials. 2 patients were studied only pre-surgery, the other 7 post-surgery. The utility of this test is discussed.

Silent period in spinal cord pathology.

The silent period evoked by the electrical stimulus of the abductor pollicis brevis and the triceps surae muscles was studied in both normal subjects and in patients affected by spinal compression, by multiple sclerosis and by familial degenerative myelopathy. In normal subjects, the duration of the silent period is shorter in the upper limbs than in the lower limbs. In patients with spinal compression and multiple sclerosis, the duration of the silent period in the lower limb is significantly greater. On the contrary, the duration in familial degenerative myelopathy is significantly longer, recording from the abductor pollicis brevis. The authors conclude that this technique is useful in the diagnosis of spinal lesions from compression and demyelination.

Anterior interosseous nerve syndrome.

Weakness of the flexor pollicis longus, flexor digitorum profundus and pronator quadratus is usually related to an isolated paralysis of the anterior interosseous nerve in the volar aspect of the forearm. The same syndrome may be caused by lesions of the median nerve in the supracondylar region and by involvement of the fibers assigned to the abovementioned nerve in the medial and lateral cords of the brachial plexus. We report 4 cases of the anterior interosseous nerve syndrome (3 spontaneous and one traumatic), review and discuss etiological factors, clinical features and electromyographic findings in the syndrome.

Laughing and running fits as manifestation of early traumatic epilepsy.

Early traumatic epilepsy, whose frequency is rather high, especially in children, is usually characterized by focal motor seizures (57%) or by generalized seizures (43%). The association of both running and laughing fits in the same patient on the contrary is quite exceptional, as only three cases have been reported in literature. There are no observations about temporal lobe epilepsy, nor, particularly, about running or laughing fits in early traumatic epilepsy. We report here the interesting case of a boy whose early traumatic epilepsy manifested itself as temporal lobe epilepsy characterized by running and laughter.

Remarks concerning 102 watersoluble contrast ventriculographies.

The Authors report their experience in using water-soluble contrast medium in ventriculographies having carried out 102 ventriculographies partly with Dimer X and partly with "Uromiro 300". Their conclusions are practically similar to those already reported by the many Authors who have written on this subject: 1) facility of examination particularly in urgent cases; 2) excellent neuroradiological definition of the cases; 3) possibility of obtaining a selective ventriculography; 4) indication especially in space-occupying lesions of the posterior cranial contrast medium; 6) possibility of reducing complication rate by carefully carrying out the examination and by avoiding the use of excessive quantities of contrast. In particular the Authors describe some useful methods for obtaining better technical results from the examination and reducing the complication rate.

Lonidamine in the combined treatment of malignant gliomas. A randomized study.

Lonidamine (LND) is a drug that interferes with energy metabolism of cancer cells, principally inhibiting aerobic glycolytic activity, by its effect on mitochondrially-bound hexokinase (HK). In such way LND could impair energy-requiring processes, as recovery from potentially lethal damage, induced by radiation treatment and by some cytotoxic drugs. A randomized study started in November 1983, to evaluate the efficacy of LND in association with radiotherapy as first line treatment in malignant gliomas, after surgical procedure. LND was also used in association with Lomustine (CCNU) at the moment of documented clinical and neuroradiological recurrence. At the present time 60 patients entered the study, and 47 are evaluable. Present preliminary results are not statistically significant, however indicate that LND tends to prolong the median survival time and the rate of one year survivors.

The effect of brain radiotherapy on the P3 component of ERP's.

Nine patients with lung cancer without brain metastasis were studied pre and post brain prophylactic radiotherapy (30 Gy) to verify the effect of radiation on the cognitive processes. The P3 component of event-related potentials was used in this study. The latencies pre and post-radiation were compared and a significant delay (p less than 0.01) was detected in patients after treatment. These results suggest that brain radiotherapy may produce a cognitive impairment, as reported by many Authors.

Segmental abdominal zoster paresis.

A case of uncommon feature of herpes zoster, a segmental abdominal paresis, is described. The importance of searching a motor defect in the thoracoabdominal segments and the utility of the electromyographic examination are stressed.

The pronator teres syndrome. Clinical and electrophysiological features in six surgically verified cases.

Six surgically verified cases of pronator teres syndrome are reported. The anatomy of the median nerve at the upper third of the forearm, the relationships between the nerve and the pronator teres muscle and the serial innervation of the muscles of the forearm supplied by the n. medians are described. Clinical and electrophysiological features are reported in detail and their contribution in diagnosing the lesion is discussed.

Spasmophilia: a clinical neurophysiopathological and biochemical study.

Spasmophilia is a problem much debated as regards its nosographic location. Its paroxysmal onset in a "neurotic" patient has confined spasmophilia within a psychiatric syndromic complex for many years. In the present study, strict clinical criteria used in selecting a population of spasmophilic patients included clinical, neurophysiological, biohumoral and psychological evaluations, providing further information about the real organic features of this syndrome. Moreover, on the basis of an organic pathogenetic hypothesis, all patients were administered medical therapy which resulted in clinical amelioration in a significant number of cases.

Early somatosensory evoked potentials in supratentorial brain tumors.

Early somatosensory evoked potentials were recorded in 33 patients with supratentorial brain tumors (9 benign tumors, 17 glioblastomas and 7 metastases). All the cases were studied with CT scan and all but 2 were surgically explored and histologically classified. Evoked potentials were statistically analyzed regarding the nature and site of the tumors. The temporal malignant tumors showed the most significant alterations in latencies, particularly for waves P25, N34 and P44.
