Five-Year Outcomes among U.S. Bronchiectasis and NTM Research Registry Patients.

Nontuberculous mycobacteria (NTM) are prevalent among patients with bronchiectasis. However, the long-term natural history of patients with NTM and bronchiectasis is not well described. To assess the impact of NTM on 5-year clinical outcomes and mortality in patients with bronchiectasis.

Scapula fractures: interobserver reliability of classification and treatment.

Objectives: There is substantial variation in the classification and management of scapula fractures. The first purpose of this study was to analyze the interobserver reliability of the OTA/AO classification and the New International Classification for Scapula Fractures. The second purpose was to assess the proportion of agreement among orthopaedic surgeons on operative or nonoperative treatment.

Classification of patients with pain based on neuropathic pain symptoms: comparison of an artificial neural network against an established scoring system.

Wider use of pain assessment tools that are specifically designed for certain types of pain--such as neuropathic pain--contribute an increasing amount of information which in turn offers the opportunity to employ advanced methods of data analysis. In this manuscript, we present the results of a study where we employed artificial neural networks (ANNs) in an analysis of pain descriptors with the goal of determining how an approach that uses a specific symptoms-based tool would perform with data from the real world of clinical practice. We also used traditional statistics approaches in the form of established scoring systems as well as logistic regression analysis for the purpose of comparison.

Continuous peripheral nerve block in replantation and revascularization.

Continuous infusion of a local anesthetic by means of a percutaneous forearm catheter and an infusion pump was studied for its utility in achieving sympathetic blockade following replantation and revascularization of the digits. The efficacy of the technique was demonstrated by cold stress testing. When the technique was used in 55 patients who underwent digital replantation or revascularization, 53 of 57 replanted digits (93 percent) and 25 of 26 revascularized digits (96 percent) survived.
