Diabetic neuropathy in some form or other afflicts a majority of patients with diabetes mellitus. Neuropathic disturbance of sensory, motor or autonomic nerves may occur singly or in combination. Cranial nerve and other mononeuropathies generally resolve spontaneously. Autonomic neuropathy which can result in orthostatic hypotension, gastroparesis diabeticorum, nocturnal diarrhea, atonic bladde...

Two Japanese persons with consanguinous parents had a motor and sensory neuropathy of the hypertrophic type with excessive myelin outfolding in the myelinated fibers. A morphometric analysis of the biopsied sural nerve was made. Excessive myelin outfolding, segmental demyelination, and remyelination and decrease in the density of both large and small myelinated fibers were evident. Using linear...

A 59-year-old man was admitted with numbness, pain, and a tingling sensation in both lower legs. He was initially diagnosed with diabetic peripheral neuropathy based on a symptom questionnaire and a quantitative sensory test. Despite symptomatic treatment of diabetic neuropathy, he complained of worsening sensory symptoms and additional motor weakness in both lower extremities. As the motor wea...

To construct a sensory neuropathy model, excess pyridoxine (150 mg/kg s.i.d.) was injected subcutaneously in dogs over a period of 7 days. During the administrations period, the dogs experienced body weight reduction and proprioceptive loss involving the hindquarters. After pyridoxine administration was completed, electrophysiological recordings showed that the M wave remained at a normal state...

Arnold's nerve ear-cough reflex is recognised to occur uncommonly in patients with chronic cough. In these patients, mechanical stimulation of the external auditory meatus can activate the auricular branch of the vagus nerve (Arnold's nerve) and evoke reflex cough. This is an example of hypersensitivity of vagal afferent nerves, and there is now an increasing recognition that many cases of refr...

Amyloid-like immunoglobulin M (IgM) deposition neuropathy associated with Waldenström macroglobulinemia is a rare phenotype of IgM-related neuropathy. The prominent clinical features are painful sensory-dominant neuropathy followed by distal motor weakness and atrophy over a long clinical course that are refractory to immunosuppressive treatment in many patients. Herein, we report a case of amy...

Sensory Guillain-Barré syndrome (GBS) is an acute demyelinating neuropathy that presents clinically with involvement of the sensory peripheral nerve only. To date, <10 cases of pure sensory GBS have been reported; thus, the clinical and pathological features of sensory variant GBS are yet to be well characterized. The current study reports the case of a 43-year-old female that presented with ac...

Quantitative sensory testing was used to assess the prevalence of sensory dysfunction in patients with cancer, carefully screened for other risk factors for neuropathy. Large fibre type sensory function was evaluated using vibration threshold (VT) determinations while small fibre type sensory function was assessed by thermal threshold (TT) determinations. Mean VT and TT were significantly eleva...

Acute autonom ic and sensory neuropathy was first described by Colan and colleagues in 1980 (1 ). The disease is characterized by autonomic dysfunction and severe sensory deficit with acute onset (2, 3). The disease is rare and is thought to be a variant form of acute pandysautonomia ( 4, 5) and Guillain-Barre syndrome (6) . Pathologically , the abnormality in this disease as found in two autop...

Silver syndrome (Silver spastic paraplegia syndrome) is a rare disorder of the peripheral nervous system that combines features of spastic paraparesis and peripheral neuropathy. The underlying genetic defects are two mutations in the BSCL2 gene which have been described in several families. Silver syndrome--related to the N88S mutation in the BSCL2 gene--is characterized by a spectrum of clinic...
