Shoulder Arthroplasty Options for Glenohumeral Osteoarthritis in Young and Active Patients (<60 Years Old): A Systematic Review.

Aim: This study aims to describe the shoulder arthroplasty options for young and active patients (<60 years old) with glenohumeral osteoarthritis.

Methods: A systematic review of the literature was conducted by searching on Pubmed database. Studies that reported outcomes of patients with glenohumeral arthritis, younger than 60 years, that underwent shoulder arthroplasty [(Hemiarthroplasty (HA), Hemiarthroplasty with biological resurfacing (HABR), Total shoulder arthroplasty (TSA), Reversed total shoulder arthroplasty (RSA)] were included.

TSDC and DSC Investigation on the Molecular Mobility in the Amorphous Solid State and in the Glass Transformation Region of Two Benzodiazepine Derivatives: Diazepam and Nordazepam.

In this work we study the molecular mobility in the amorphous solid state and in the glass transformation region of two compounds, diazepam and nordazepam; these are two benzodiazepines, a family of psychotropic drugs with sedative, anxiolytic and muscle-relaxing properties. The experimental techniques used are thermostimulated currents (TSC) and differential scanning calorimetry (DSC). TSC is a time-dependent technique recognized for its high resolving power; the use of this technique in the depolarization and polarization modes (TSDC and TSPC respectively), provides results that confirm and complement results of dielectric relaxation spectroscopy (DRS) published recently.

Comparison of short-stem versus conventional stem for hip arthroplasty in patients younger than 60 years: 7-14 years follow-up.

Purpose: Short-stem prostheses in hip arthroplasty have emerged as an alternative to conventional stems, especially in younger patients. The purpose of this study was to compare functional and radiological results of a short metaphyseal fitting cementless stem versus a conventional stem implant, in patients younger than 60 years.

Methods: All patients operated from January 2006 to April 2013 were included, obtaining a minimum follow-up of 7 years.

Tuberosity Healing after Reverse Shoulder Arthroplasty for Proximal Humerus Fractures: Is there Clinical Improvement?

 To compare the functional results of patients with complex proximal humerus fracture submitted to total shoulder reverse arthroplasty with and without tuberosity healing. The secondary goal was to know the tuberosity healing rate after reverse shoulder arthroplasty with our surgical technique.  A retrospective, cohort type study, with a prospective database collection.

Isolated traumatic posterior dislocation of the radial head in an adult, a rare injury: New case report.

Isolated radial head dislocations are rare in adults with only 23 cases published in 45 years. The diagnosis may be easily missed on radiographs and a CT-scan is often required. If managed promptly patient can restore normal range of motion and elbow function.

The slow relaxation dynamics in active pharmaceutical ingredients studied by DSC and TSDC: Voriconazole, miconazole and itraconazole.

The slow molecular mobility of three active pharmaceutical drugs (voriconazole, miconazole and itraconazole) has been studied by differential scanning calorimetry (DSC) and thermally stimulated depolarization currents (TSDC). This study yielded the main kinetic features of the secondary relaxations and of the main (glass transition) relaxation, in particular their distribution of relaxation times. The dynamic fragility of the three glass formers was determined from DSC data (using two different procedures) and from TSDC data.

Moderate exercise improves depression parameters in treatment-resistant patients with major depressive disorder.

Background: Treatment-resistant major depressive disorder (MDD) is a complex condition, with very low remission rates. Physical exercise has been used, with some encouraging results, as an alternative therapy in other depressive disorders. This study assessed the impact on depression and functioning parameters of a moderate intensity exercise program, as an adjuvant to pharmacotherapy, in treatment-resistant MDD patients.

Bilateral posterior fracture-dislocation of the shoulder: Report of two cases.

Bilateral posterior fracture-dislocation of the shoulder is a very rare injury. Almost 50% of bilateral posterior dislocations are due to a convulsive seizure, rising to 90% if the dislocations are associated with fractures. Electric shock accounts for less than 5% of bilateral posterior dislocations of the shoulder.

Estimation of the fragility index of indomethacin by DSC using the heating and cooling rate dependency of the glass transition.

In this study we have investigated the features of the glass transition relaxation of indomethacin using Differential Scanning Calorimetry (DSC). The purpose of this work is to provide an estimation of the activation energy at the glass transition temperature, as well as of the fragility index, of amorphous indomethacin from DSC data. To do so, the glass transition temperature region of amorphous indomethacin was characterized in both cooling and heating regimes.

The activation energy at Tg and the fragility index of indomethacin, predicted from the influence of the heating rate on the temperature position and on the intensity of thermally stimulated depolarization current peak.

Purpose: The purpose of this study was to estimate the activation energy at the glass transition temperature (and the fragility index) of amorphous indomethacin from the influence of heating rate on the features of the relaxation peaks obtained by thermally stimulated depolarization currents (TSDC) and to compare the obtained results with those obtained by other procedures based on TSDC data.

Methods: The glass transition temperature region of amorphous indomethacin was characterized at different heating rates by TSDC in a way similar to that used to determine the kinetics of the glass transition relaxation by differential scanning calorimetry. The features of a thermal sampled TSDC peak, namely the temperature location and the intensity, depend on the heating rate.
