INTRODUCTION Notalgia paresthetica is a sensory mononeuropathy that affects dorsal segments T2 to T6. It can have a significant effect on quality of life. Numerous treatments have been used with variable results. MATERIAL AND METHODS Five patients diagnosed with notalgia paresthetica were treated with intradermal botulinum toxin A. None had achieved relief of the pruritus with previous treatm...

INTRODUCTION The objective of this study was to determine whether a hand diagram could be used to predict ulnar mononeuropathy. METHODS This was a prospective study of 117 consecutive patients referred for hand symptoms. Each subject filled out a hand diagram of symptoms and had median and ulnar sensory and motor nerve conduction studies, including ulnar conduction across the elbow. RESULTS...

Neuropathies are among the most common of all the long-term complications of diabetes, affecting up to 50% of patients.1–5 There are many subgroups of neuropathies; readers are referred to recent reviews for discussion of the autonomic neuropathies6 and the mononeuropathies.7 This article will focus on the most common of all the peripheral neuropathies: the somatic neuropathies affecting the lo...

INTRODUCTION We report a rare case of fulminant vasculitic mononeuropathy resulting in brachial diplegia, with suspected brainstem and autonomic nervous system involvement in a patient with diabetes mellitus. CASE PRESENTATION A 58-year-old Hispanic Caucasian man with diabetes mellitus presented with a 1-year history of progressive bilateral upper extremity weakness, orthostatic intolerance a...

Neuritis ossificans is a rare reactive process affecting the peripheral nerves that is challenging to diagnose and treat. The usual presentation is mononeuropathy, pain, variable weakness, and a palpable mass along the nerve distribution. A paucity of literature exists on this disorder. It is often confused with myositis ossificans; many cases in the literature have reported myositic masses tha...

IMPORTANCE The newly recognized entity IgG4-related disease (IgG4-RD) is characterized by an elevated IgG4 serum concentration and tissue infiltration by IgG4-positive plasma cells. We describe, for the first time, the clinical features and nerve biopsy findings of a patient with IgG4-RD who presented with neuropathy in the extremities. OBSERVATIONS A 55-year-old man had histopathologically d...

Bariatric surgical procedures are increasingly common. In this review, we characterize the neurologic complications of such procedures, including their mechanisms, frequency, and prognosis. Literature review yielded 50 case reports of 96 patients with neurologic symptoms after bariatric procedures. The most common presentations were peripheral neuropathy in 60 (62%) and encephalopathy in 30 (31...

BACKGROUND Hereditary neuropathy with liability to pressure palsies (HNPP) is an autosomal-dominant painless peripheral neuropathy characterized by episodes of repeated focal pressure neuropathies at sites of entrapment/compression, with a considerable variability in the clinical course. Electrodiagnostic and genetic testing are important in the diagnostic evaluation of these patients. CASE P...

Hereditary neuropathy with liability to pressure palsy is characterized by acute, painless, recurrent mononeuropathies secondary to minor trauma or compression. A 16-year-old boy had the first episode of right foot drop after minor motorcycle accident. Electromyography revealed conduction block and slowing velocity conduction of the right deep peroneal nerve at the fibular head. After motor reh...

• Eosinophilic granulomatosis with polyangiitis (EGPA), formerly known as Churg-Strauss syndrome The respiratory system is commonly involved in all three syndromes, which share certain histopathologic and clinical features. Other features are unique and diseasedefining (Table 1). Diffuse alveolar hemorrhage (Figure 1, A1, see page 2) is a potentially life-threatening complication of each of the...
