Minimal important difference after hand surgery: a prospective assessment for DASH, MHQ, and SF-12.

Introduction: Minimal important difference (MID) score is an important measure for surgical clinical research and impacts on treatment decisions. Our approach considered patient satisfaction as the relevant anchor criteria. The aims of this study were: determine after surgery MID for three relevant questionnaires: Disabilities of the Arm, Shoulder and Hand (DASH), Michigan Hand Questionnaire (MHQ), and Short Form 12 (SF-12); and assess the correlation between these scores and patient reported satisfaction.

Translation and Cross-Cultural Adaptation of the 6-Item Carpal Tunnel Syndrome Symptoms Scale and Palmar Pain Scale Questionnaire Into Brazilian Portuguese.

Background: There are several medical questionnaires to evaluate the quality of life of carpal tunnel syndrome patients. However, most measures are only available in English. We chose to translate and culturally adapt to Portuguese the Six-Item Carpal Tunnel Syndrome Symptoms Scale and Palmar Pain Scale (CTS-6) questionnaire because it provides objective assessment using a small number of questions.

Peripheral nerve regeneration with conduits: use of vein tubes.

Treatment of peripheral nerve injuries remains a challenge to modern medicine due to the complexity of the neurobiological nerve regenerating process. There is a greater challenge when the transected nerve ends are not amenable to primary end-to-end tensionless neurorraphy. When facing a segmental nerve defect, great effort has been made to develop an alternative to the autologous nerve graft in order to circumvent morbidity at donor site, such as neuroma formation, scarring and permanent loss of function.

Does dorsal capsule interposition improve the results of proximal row carpectomy in Kienböck's disease? One year randomized trial.

Introduction: Proximal row carpectomy (PRC) is an option as a salvage procedure in late stage Kienböck's disease. In this study, we hypothesize that interposition of a dorsal capsular flap following PRC improves functional outcomes. No comparative study is available to assess whether interposition is effective from the functional perspective.

Identification of QTLs for Resistance to Sclerotinia sclerotiorum in Carioca Common Bean by the Moving Away Method.

The aim of this study was to use multiple DNA markers for detection of QTLs related to resistance to white mold in an F2 population of common bean evaluated by the straw test method. The DNA from 186 F2 plants and from the parents was extracted for genotypic evaluation using SSR, AFLP, and SRAP markers. For phenotypic analysis, 186 F2:4 progenies and ten lines were evaluated, in a 14 × 14 triple lattice experimental design.

Percutaneous release of trigger fingers.

Open surgery has been indicated as the surgical treatment for trigger finger for many years; however, minimally invasive techniques are replacing conventional methods. Minimally invasive techniques enable early recovery of the patient with minimal damage to soft tissues. The authors’ study showed that levels of effectiveness of open surgical and percutaneous methods were superior to those of the conservative method using corticosteroid based on the cure and reappearance rates of the trigger.
