BACKGROUND: Chemotherapy-induced peripheral neuropathy (CIPN) seriously affects the quality of life of patients with multiple myeloma (MM) as well as the response rate to chemotherapy. Acupuncture has a potential role in the treatment of CIPN, but at present there have been no randomized clinical research studies to analyze the effectiveness of acupuncture for the treatment of CIPN, particularly in MM patients. METHODS: The MM patients (104 individuals) who met the inclusion criteria were randomly assigned into a solely methylcobalamin therapy group (500 μg intramuscular methylcobalamin injections every other day for 20 days; ten injections) followed by 2 months of 500 μg oral methylcobalamin administration, three times per day) and an acupuncture combined with methylcobalamin (Met + Acu) group (methylcobalamin used the same way as above accompanied by three cycles of acupuncture)...

Ulnar nerve entrapment is the second most common compressive neuropathy after carpal tunnel syndrome. The accessory anconeus epitrochlearis muscle - present in 4% to 34% of the general population - is a known, but rare cause of ulnar nerve entrapment at the elbow. The aim of this article was to expand our knowledge about this condition based on six cases that we encountered at our hospital between 2011 and 2015. Every patient had a typical clinical presentation: hypoesthesia or sensory deficit in the fourth and fifth fingers; potential intrinsics atrophy of the fourth intermetacarpal space; loss of strength and difficulty with fifth finger abduction...

BACKGROUND: Nerve injuries resulting from major or minor trauma often cause some disabilities for patients. Neurotmesis, characterized by complete anatomical rupture of the nerve, is the most severe form of the injury which will not recover without reconstructive surgery and nowadays such neural damages are improved by microsurgical procedures. Some studies have used low power laser for nerve cell growth in order to improve the rehabilitation results of peripheral nerves. Low power laser can complement the reformation of postsurgical nerve injuries...

Proximal median (PMNE) and radial (RNE) nerve entrapment syndromes are uncommon. This article provides an evidenced-based treatment guideline for PMNE and RNE based on the available literature. Arriving at an accurate diagnosis must involve an electrodiagnostic (EDx) workup. EDx, including nerve conduction velocity studies and needle electromyography, should corroborate the clinical diagnosis and must be done before consideration of any surgical treatment. Conservative care includes rest, modified activities, splinting at wrist and elbow, physical therapy, antiinflammatory drug therapy, and corticosteroid injections...
