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.
