Randomized Controlled Trial Comparative StudyA Randomized Prospective Comparison of Ultrasound-Guided and Landmark-Guided Steroid Injections for Carpal Tunnel Syndrome.
The aim of this study was to compare the clinical and electrodiagnostic efficacy of ultrasound (US)-guided versus landmark (LM)-guided steroid injections in patients with carpal tunnel syndrome (CTS). ⋯ Both US-guided and LM-guided steroid injections were effective in reducing the symptoms, improving the function and electrodiagnostic findings of CTS. Although there was better symptomatic improvement with US-guided injections and better increase in sensory nerve action potential amplitude with LM-guided injection, a significant difference was not generally observed between US-guided and LM-guided CTS injections.

Comparative StudyCompound Muscle Action Potential Decrement to Repetitive Nerve Stimulation Between Hirayama Disease and Amyotrophic Lateral Sclerosis.
To compare repetitive nerve stimulation (RNS) between Hirayama disease (HD) and amyotrophic lateral sclerosis (ALS). ⋯ The significantly different RNS results between ALS and HD patients support the application of RNS, especially performing RNS in proximal muscles, as a supplementary test in distinguishing these two diseases, even in the early stages. These results may also imply a difference in underlying pathophysiology between ALS and HD.

Quantification of Chronic Oxaliplatin-Induced Hypesthesia in Two Areas of the Hand.
Oxaliplatin is a platinum derivate widely used in cancer treatment but producing dose-limiting peripheral neurotoxicity. Acute neuropathy is characterized by a transient cold-induced distal allodynia, whereas chronic neuropathy leads to sensory loss. To design a method for quantitative assessment of oxaliplatin-induced peripheral neuropathy, we developed a study that aims to characterize the most appropriate skin area of the hand to perform sensory tests. ⋯ These results reveal that distal hypesthesia occurring under treatment with oxaliplatin is markedly pronounced in the fingertips; however, as thermal threshold is unknown before treatment, it is difficult to assert that fingertip thermal hypesthesia has developed under treatment. Finally, this short study may be useful to design a method for quantifying oxaliplatin-induced neuropathy.
