Magnetic resonance neurography is a technique that complements clinical and electrophysiological study of the peripheral nerves and brachial and lumbosacral plexuses. Numerous focal processes (inflammatory, traumatic, primary tumors, secondary tumors) and diffuse processes (diabetic polyneuropathy, chronic idiopathic demyelinating polyneuropathy due to amyloidosis or Charcot-Marie-Tooth disease...

The term diabetic polyneuropathy is probably the one you will encounter most frequently during your medical studies. What are the most common causes of polyneuropathy? Which are hereditary, and which are acquired? How are they diagnosed and what types of therapy are available? The following article will provide you with answers to all of these questions. It has been prepared with the medical ex...

Intoxications due to organophosphate insecticides are common in our country, since agriculture has an important place. Besides the well known acute cholinergic toxicity, these compounds may cause late-onset distal polyneuropathy occurring two to three weeks after the acute exposure. An eight-year-old boy and a 13-year-old girl admitted to the hospital with gait disturbances. Beginning 15 and 20...

Adenosine deaminase deficiency is a type of severe combined immunodeficiency that involves about 15% of all SCID cases. This form of SCID has low B cells, T cells, and NK cells. This condition is complex with many possible complications including neurological abnormalities. Guillainbarré syndrome is an acute inflammatory disease of the peripheral nerves that involves an autoimmune attack on mye...

POEMS (polyneuropathy, organomegaly, endocrinopathy, M-band, and skin changes) syndrome is characterized by chronic progressive polyneuropathy and plasma-cell dyscrasia. A major diagnostic criterion of POEMS is elevation of circulating vascular endothelial growth factor (VEGF), which is believed to play a pathogenic role in this disease. We report a case of POEMS that presented as relapsing acu...

Guillain-Barre syndrome, an acute or subacute inflammatory demyelinating polyradiculoneuropathy, usually causes ascending paralysis, areflexia, and sensory disturbances. l A similar syndrome, more chronic and sometimes relapsing, has been called chronic inflammatory demyelinating polyneuropathy.2 Thought to have an immunologic cause, Guillain-Barre syndrome can be found in association with infe...

Twelve patients with familial amyloidosis with polyneuropathy were examined both by cross sectional echocardiography and by technetium-99m pyrophosphate scintigraphy to assess involvement of the heart non-invasively. All 12 patients had echocardiographic abnormalities. The most prominent findings were highly refractile myocardial echoes, thickened heart valves, and increased thickness of the he...

BACKGROUND Polyneuropathy organomegaly endocrinopathy M-protein skin changes (POEMS) syndrome is a rare cause of polyneuropathy. Calciphylaxis, a severe disease leading to necrotic ulcers of the skin, is associated with POEMS syndrome and also with renal disease. This case report describes a patient with POEMS syndrome plus primary focal segmental glomerulosclerosis. CASE PRESENTATION A 27-ye...

INTRODUCTION Sensory chronic inflammatory demyelinating polyneuropathy (CIDP) can be difficult to diagnose. METHODS We report 22 patients with chronic sensory polyneuropathy with ≥1 clinical sign atypical for chronic idiopathic axonal polyneuropathy (CIAP) but no electrodiagnostic criteria for CIDP. RESULTS Clinical signs atypical for CIAP were: sensory ataxia (59%), generalized areflexia (...

Neurological findings were examined in 186 forestry workers with a mean exposure to chain saw vibration of 16.6 hours. The prevalence of active vibration induced white fingers was 5%, parethaesias of the hands 53%, and muscle weakness 13%. Clinical polyneuropathy was observed in 16 forestry workers in the hands (7.5%) which did not correlate with alcohol consumption. Seventy nine forestry worke...
