Introduction: Ulnar neuropathy at the elbow (UNE) is the second most common entrapment neuropathy. Our goal was to create and analyze a grading system for UNE electrodiagnostic severity. Methods: We retrospectively analyzed EMG reports with UNE. We then classified 112 limbs as having mild, moderate, or severe grade UNE based on electrodiagnostic findings. The association between presenting symptoms and signs, EMG findings, treatment type, and electrodiagnostic grade was statistically analyzed. Results: Seventeen limbs (15.2%) had mild, 80 (71.4%) had moderate, and 15 (13.4%) had severe UNE. Symptoms (P =.016), exam findings (P <.001), and treatment type (P =.043) were significantly associated with electrodiagnostic grade. Discussion Our UNE grading system was significantly related to symptoms, physical exam, and treatment selection and may be useful to measure electrodiagnostic severity. [ABSTRACT FROM AUTHOR]

Introduction: Causes of small-fiber peripheral neuropathies (SFN) are often undefined. In this study we investigated associations of serum autoantibodies, immunoglobulin G (IgG) vs fibroblast growth factor receptor-3 (FGFR-3), and immunoglobulin M (IgM) vs trisulfated heparan disaccharide (TS-HDS) in cryptogenic SFN.Methods: One hundred fifty-five patients with biopsy-proven SFN and no identified cause for their neuropathy were blindly tested for serum IgM vs TS-HDS and IgG vs FGFR-3.Results: Forty-eight percent of SFN patients had serum antibodies, 37% with IgM vs TS-HDS and 15% with IgG vs FGFR-3. TS-HDS antibodies were more frequent in SFN patients than in controls (P = .0012). Both antibodies were more common in females, and with non-length-dependent nerve pathology. Nintey-two percent of patients with acute-onset SFN had serum IgM vs TS-HDS.Discussion: Autoantibodies directed against TS-HDS and FGFR-3 suggest an immune disorder in otherwise idiopathic SFN. Serum IgM vs TS-HDS may be a marker for SFN with an acute onset. [ABSTRACT FROM AUTHOR]

Introduction: Prior studies have demonstrated superiority of the combined sensory index (CSI) algorithm in diagnosing mild carpal tunnel syndrome (CTS) and have compared presenting symptoms to CTS grade. However, CTS symptoms, signs, and outcomes, including CSI-diagnosed cases, have not been compared with CTS grade.Methods: We retrospectively studied 294 CTS hands from 2010 to 2013; stratified them into mild, moderate, and severe grades; and analyzed the association between CTS grade and presenting symptoms/signs and outcomes.Results: Sensorimotor symptoms (P = 0.017) and signs (P < 0.001) were significantly associated with CTS grade. Regardless of CTS grade, 94% of hands improved with surgery compared with 42% with conservative treatment (P < 0.001). Even in mild CTS, 100% improved with surgery vs. 33% with conservative management (P = 0.011).Discussion: These results corroborate prior studies that compared symptoms to CTS grade and suggest that more objective signs associate even better. CTS grades associate with outcomes, but additional studies are required. Muscle Nerve 57: 45-48, 2018. [ABSTRACT FROM AUTHOR]

ABSTRACT: Johannes Pompe is famous for describing type II glycogenosis, Pompe disease. However, Pompe's participation in the Dutch resistance during World War II has not been well described in the neurology literature. Pompe saved many Jews by hiding them as patients, saved a Jewish boy who was a neighbor, hid many young resistance fighters in his laboratory, resisted the Nazi call for all Dutch doctors to submit to their puppet physician's chamber, and hid a radio transmitter in the animal room of his laboratory. He was executed by firing squad in a German reprisal shortly before the end of the war. Pompe's patriotism and religious and humanitarian values seem to have been the basis for his actions. His heroic and tragic story should not be forgotten and should serve as an example to all during such dark times. Muscle Nerve 46: 134-138, 2012 [ABSTRACT FROM AUTHOR]
