Current concepts in the diagnosis of transverse myelopathies

The clinical symptoms and MRI characteristics of transverse myelopathy (TM) due to non-compressive causes are reviewed, with special emphasis on the differential diagnosis between inflammatory demyelinating lesions, and metabolic and vascular myelopathies. Inflammatory transverse myelopathies are the commonest and most difficult ones to identify. The differentiation between clinically isolated syndromes, multiple sclerosis, neuromyelitis optica, acute disseminated encephalomyelitis and metabolic causes is based on both clinical symptoms and paraclinical signs including magnetic resonance imaging, cerebrospinal fluid analysis, and immunological and biochemical parameters. The most intriguing form of TM is that where there is clinical evidence of complete spinal cord transection, with normal findings in magnetic resonance imaging in the acute phase, but subsequent cord atrophy.

CNS demyelination in autoimmune diseases

Autoimmune diseases represent a diverse group of disorders that have generally of unknown etiology and poorly understood pathogenesis. They may be organ-specific or systemic, giving rise to overlapping syndromes; more than one autoimmune disease may occur in the same patient. Numerous case reports have documented that multiple sclerosis (MS) may be present concurrently with other autoimmune diseases, most commonly rheumatoid arthritis, autoimmune thyroid disease, type I diabetes mellitus and pernicious anemia. Case reports of disseminated encephalomyelitis (DEM) coincidental with other autoimmune diseases are rare. Many of systemic autoimmune diseases cause central nervous system (CNS) demyelination and are frequently then diagnosed as MS, whereas they often are instances of DEM, the result of vascular, granulomatous or postinfectious manifestations. We have reviewed 15 patients with autoimmune diseases and CNS demyelination in order to determine the nature of the demyelinating process.

Severe progression of ALS / MND after intervertebral discectomy

We observed seven patients who developed their first signs and symptoms of motor neuron disease together with signs of protrusion/prolapse of intervertebral disc. The age of the patients was between 55 and 67, of which one female and six male patients. All of them suffered from cervical spine pain or low back pain. The female patient and one male patient developed weakness in the small feet muscles as initial symptom and they complained of paresthesia along dermatomes L5S1 and of severe pain. The other five patients developed wasting of the hands muscles. They had a rather mild pain in the cervical spine and early morning paresthesia as well as severe causalgia along dermatomes C5C6 or C6C7. After the diagnosis of compressive radiculopathy in all patients, they underwent surgical treatment and very soon developed very severe progression of muscle wasting which included muscles of limbs, trunk and bulbar innervated muscles with signs and symptoms of lower and upper motor neuron lesion. Five patients died from 12 to 15 months after surgical treatment and two patients are still living.

Motor neurone disease associated with several immunological disorders: A case report

A 44-year-old woman developed rheumatoid arthritis, pemphigus vulgaris and myasthenia gravis. Motor neurone disease appeared 2 years later. Hashimotos thyroiditis was diagnosed after a severe stress in the autumn of 1991.

Stiff-person syndrome in a female patient with type 1 diabetes, dermatitis herpetiformis, celiac disease, microcytic anemia and copper deficiency Just a coincidence or an additional shared pathophysiological mechanism?

The low level of serum copper in presented patient with Stiff-person syndrome, type 1 diabetes, dermatitis herpetiformis, celiac disease and microcytic anemia opens a question of the role of copper and possibly other trace elements in the development of autoimmune diseases.
