[Clinical value of SPECT scanning in children with neurological disorders].

We retrospectively evaluated the clinical value of Tc-99-HMPAO brain single photon emission tomography (SPECT) in 21 children with neurological disorders of varied aetiology. All 21 patients were examined with electroencephalograms (EEGs), 17 with computed tomography (CT) and ten with magnetic resonance imaging (MR). New relevant information was obtained from SPECT in all 21 cases and in four of these cases the investigation directly led to a change in diagnosis and better assessment of the prognosis. It is concluded that SPECT is an important investigational method in children with neurological symptoms of partly or completely unknown aetiology.

["The withered arm". A multifocal motor neuropathy and considerations in differential diagnosis].

Multifocal motor neuropathy (MMN) is a newly recognized disorder with a characteristic clinical picture. The diagnosis of MMN is established by the presence of a specific electrodiagnostic abnormality, conduction block confined to motor axons, and in some instances by the associated high titers of anti-GM1 antibodies. Clinical improvement may be achieved by treatment with intravenous immunoglobulin or cyclophosphamide, which underlines the importance of recognizing these patients. We present two patients with slowly progressive predominantly distal weakness and muscle wasting of an upper extremity characteristic of MMN. Extensive electrophysiological examinations are necessary to demonstrate conduction block of motor axons, which distinguishes patients with MMN from patients with motor neuron disease. Other diagnostic possibilities are discussed.

[Chronic inflammatory demyelinating polyradiculoneuropathy].

During recent years chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) has been characterized on the basis of clinical and laboratory findings. Immune modifying treatment with glucocorticoids, plasma exchange and infusion of immune globulins has had a therapeutic effect in controlled studies. Decisive for increased therapeutic efforts against CIDP in Denmark is intensified electrophysiological search in patients with polyneuropathy with examination of several nerve segments for evidence of demyelination including conduction block, potential dispersion and reduction of conduction velocity by more than 40%.

A case of malignant lymphoma and myasthenia gravis.

A 25-year-old man with myasthenia gravis and a non-Hodgkin lymphoma stage III B involving the thymus, is reported. The association myasthenia gravis and non-Hodgkin lymphoma has not been described previously. Treatment with chlormetin, vincristine, procarbazine, prednisone (MOPP) resulted in complete remission of both the myasthenic symptoms and the malignant lymphoma.
