On ethylene oxide neurotoxicity: report of two cases of peripheral neuropathy.

Two cases of clinically and electromyographically proven ethylene oxide neuropathy occurred among 12 workers at the Lecco Hospital Sterilization Center. Cessation of exposure to the gas, which had lasted for two years, was followed by swift remission of the symptoms and complete normalisation of the EMG record at follow-up six months later. The paucity of published data on the subject may well mean that the real risk of ethylene oxide toxicity is being underrated.

Paroxysmal kinesigenic choreoathetosis. Case report.

A case of sporadic, idiopathic, paroxysmal kinesigenic choreoathetosis is described. The frequent attacks triggered by the initial phase of voluntary movement responded well to treatment with diphenylhydantoin. The nosological, etiopathogenetic, clinical and therapeutic aspects of paroxysmal choreoathetosis are discussed and the literature reviewed.

[Hypothyroid neuropathy. Description 2 cases].

Although neurological complications of hypothyroidism are well recognized, scanty data, to the best of our knowledge, are available about peripheral neuropathies in this condition. The electrographic studies so far performed are nearly all devoted to the well known association myxoedema-carpal tunnel syndrome. Our data concern two patients affected by neuropathy in hypothyroidism, presenting diffuse anomalies of electrographic parameters (motor and sensitive nerve conduction velocity, F-wave, H-reflex, H-index); and, in one of these cases, a marked segmental demyelination and axonal degenerations were disclosed by pathological examination of sural nerve (according to Dyck and Lambert, 1970; Shirabe and coll.

The significance of cyclic EEG changes in Creutzfeldt-Jakob disease: prognostic value of their course in 9 patients.

The diagnostic value of the EEG in Creutzfeldt-Jakob disease is based not only on the presence of a typical pattern of periodic discharges but also on the appearance of cyclic changes in the EEG. The pattern of the cyclic EEG changes was analysed in 9 patients with Creutzfeldt-Jakob disease. The changes appear when the level of wakefulness is reduced.

[Epilepsy in later life: seizures persisting after the age of 60].

In a group of 657 epileptic patients there were 51 presenting with fits even after having reached the age of 60. The onset of seizures dated back to the first 20 years in 15 patients between 20 and 40 years in 15 and between 40 and 60 years in 21. In 67% of the cases it was possible to determine the cause of seizures.

[Epilepsy in the third age: seizures presenting after the age of 60 years (author's transl)].

In a group of 400 epileptic inpatients of the Neurological Clinic of Parma, 82 were over 60 years of age. Only 59 of them presented fits for the first time after the 60th year of age and in 78% of these, a definite anatomical damage could be demonstrated (neuroradiological investigations). One half of the epileptic syndromes with known etiology were thought to be related to cerebrovascular disease, but only few cases followed a stroke with persistent neurological symptoms.
