Multicenter Study
Health-related quality of life after upper extremity injuries and predictors for suboptimal outcome.
The purpose of this study was to examine the impact of upper extremity injuries (UEIs) on health-related quality of life (HRQoL) in adult patients compared with victims of other types of injuries and with the general population, in order to establish recovery patterns of different types of UEIs and determine predictors for suboptimal outcome in the long term. ⋯ The impact of UEIs on HRQoL exceeds the health consequences of the group with all injuries. Proximal UEIs had a lower HRQoL and slower recovery than distal injuries. The predictors for the outcome on specific UEIs need to be further investigated in clinical studies, to understand how these differences affect patient-reported outcome measures. These data provide additional insight into treatment outcome and are needed to improve quality of care.

Multicenter Study Comparative Study
Sensory signs in complex regional pain syndrome and peripheral nerve injury.
This study determined patterns of sensory signs in complex regional pain syndrome (CRPS) type I and II and peripheral nerve injury (PNI). Patients with upper-limb CRPS-I (n=298), CRPS-II (n=46), and PNI (n=72) were examined with quantitative sensory testing according to the protocol of the German Research Network on Neuropathic Pain. The majority of patients (66%-69%) exhibited a combination of sensory loss and gain. ⋯ However, in contrast to recent suggestions, small fiber deficits were less frequent than large fiber deficits. Sensory gain is highly prevalent in PNI, indicating a better similarity of animal models to human patients than previously thought. These sensory profiles should help prioritize approaches for translation between animal and human research.

Multicenter StudyTraumatic peripheral nerve injuries: epidemiological findings, neuropathic pain and quality of life in 158 patients.
The objectives of this study were (1) epidemiological analysis of traumatic peripheral nerve injuries; (2) assessment of neuropathic pain and quality of life in patients affected by traumatic neuropathies. All consecutive patients with a diagnosis of traumatic neuropathies from four Italian centres were enrolled. Electromyography confirmed clinical level and site diagnosis of peripheral nerve injury. ⋯ Moreover, there was a strong correlation between the quality of life and the severity of the pain, particularly neuropathic pain (Short Form-36 [SF-36] p < 0.005; Beck Depression Inventory [BDI] p < 0.0001). Traumatic neuropathies were more frequent in young males after road accidents, mainly in the upper limbs. Severe neuropathic pain and not only disability contributed to worsening the quality of life in patients with traumatic neuropathies.

Randomized Controlled Trial Multicenter Study Comparative Study
Gabapentin in traumatic nerve injury pain: a randomized, double-blind, placebo-controlled, cross-over, multi-center study.
A double-blind, randomized, placebo-controlled cross-over multi-center study was conducted to evaluate the efficacy and safety of gabapentin in the treatment of neuropathic pain caused by traumatic or postsurgical peripheral nerve injury, using doses up to 2400 mg/day. The study comprised a run-in period of two weeks, two treatment periods of five weeks separated by a three weeks' washout period. The primary efficacy variable was the change in the mean pain intensity score from baseline to the last week of treatment. ⋯ Both the Patient (p=0.023) and Clinician (p=0.037) Global Impression of Change indicated a better response with gabapentin compared with placebo. Gabapentin was well tolerated. The most common adverse effects were dizziness and tiredness.
