Long-term results of arthroscopic repair of type II SLAP lesions in sports: assessment of return to pre-injury playing level and critical risk factors for complication.

Purpose: The management of isolated SLAP lesions is still debated especially in athletes. Aims of the study were: 1. to analyse our algorithm to treat SLAP lesions starting from the selection of patients for surgery and 2.

Therapeutic and prognostic predictive value of the Control Volume severity grade on proximal humerus fractures due to bone fragility.

Background: The treatment of proximal humerus fracture complicated by bone fragility is still controversial. The aim of this study is to compare the Neer classification and the Control Volume severity grade for the accuracy in the selection of the type of treatment and for prognostic evaluation.

Materials And Methods: We retrospectively collected the records of all patients admitted at the Emergency Department of our Institute, from 2013 to 2020, for a closed displaced proximal humerus fracture further investigated with a CT scan before treatment decision.

Osteochondral allograft transplantation for complex distal humeral fractures assisted by 3D computer planning and printing technology: technical note.

Purpose: The surgical treatment of comminuted distal humeral articular fractures (DHF) is challenging and is jeopardized by the high rate of complications. The study aims to describe the application of osteochondral allograft (OCA) transplantation for the treatment of complex DHF assisted with a 3D printed specific instrumentation.

Methods: Retrospective study.

A new classification of impacted proximal humerus fractures based on the morpho-volumetric evaluation of humeral head bone loss with a 3D model.

Background: This study aimed to classify the pathomorphology of impacted proximal humeral fractures according to the control volume theory, with the intention to introduce a severity index to support surgeons in decision making.

Methods: In total, 50 proximal humeral fractures were randomly selected from 200 medical records of adult patients treated from 2009 to 2016. Four nonindependent observers used 2 different imaging modalities (computed tomography scans plus volume rendering; 3D model) to test the classification reliability.

Analysis of early and late clinical and radiologic complications of proximal humeral fractures using open reduction, internal fixation, and intramedullary titanium cage augmentation.

Background: An intramedullary augmentation technique using a titanium cage with different types of hardware can be considered a new option in the management of proximal humeral fractures. This study aimed to report the perioperative, early, and late complications of proximal humeral fractures using the intramedullary augmentation technique.

Methods: From 2005 to 2017, 142 displaced proximal humeral fractures were treated in the same unit by the aforementioned technique.

3D laser scanning in conjunction with surface texturing to evaluate shift and reduction of the tibiofemoral contact area after meniscectomy.

Meniscectomy significantly change the kinematics of the knee joint by reducing the contact area between femoral condyles and the tibial plateau, but the shift in the contact area has been poorly described. The aim of our investigation was to measure the shift of the tibiofemoral contact area occurring after meniscectomy. We used laser scans combined to surface texturing for measuring the 3D position and area of the femoral and tibial surfaces involved in the joint.

Endogenous isoflavone methylation correlates with the in vitro rooting phases of Spartium junceum L. (Leguminosae).

Spartium junceum L. (Leguminosae) is a perennial shrub, native to the Mediterranean region in southern Europe, widespread in all the Italian regions and, as a leguminous species, it has a high isoflavone content. An in vitro culture protocol was developed for this species starting from stem nodal sections of in vivo plants, and isoflavone components of the in vitro cultured tissues were studied by means of High Performance Liquid Chromatography (HPLC) analytical techniques.

Micropropagation of Helleborus through axillary budding.

Helleborus genus, belonging to the Ranunculaceae family, has 20 species of herbaceous perennial flowering plants. The commercial exploitation of this plant is dependent on the selection and propagation of appropriate lines. High propagation rate could be accomplished by using a suitable tissue culture method enabling the rapid introduction of valuable selections in the market.

Multiple symmetric lipomatosis: a review of 3 cases.

Multiple symmetrical lipomatosis, or Madelung's disease, is a rare disease of unknown etiology. It is characterized by the presence of loose adipose tissue deposits localized in the cervical region and in the upper body. The neoformations grow slowly and their initial consequence is purely esthetic.

Comparing postoperative quality of life in children after microdebrider intracapsular tonsillotomy and tonsillectomy.

Objective: To evaluate postoperative quality of life in patients undergoing microdebrider intracapsular tonsillotomy and adenoidectomy (PITA) in comparison with traditional adenotonsillectomy (AT) and to assess PITA's efficacy in solving upper-airway obstructive symptoms.

Methods: 29 children with adenotonsillar hyperplasia referred for AT were included. Patients were divided into two groups: Group 1 (underwent PITA) included 14 children (age 5.

Voice therapy for laryngeal hemiplegia: the role of timing of initiation of therapy.

Objective: Laryngeal hemiplegia, also known as vocal fold paralysis, causes severe communicative disability. Although voice therapy is commonly considered to be beneficial for improving the voice quality in several voice disorders, there are only a few papers that present scientific evidence of the effectiveness of voice therapy in treating the disabilities of laryngeal hemiplegia. The aim of this study was to evaluate the outcomes of voice therapy in patients with laryngeal hemiplegia and to evaluate the role of the time gap between onset of laryngeal hemiplegia and initiation of therapy.

Biochemical basis for retinol deficiency induced by the I41N and G75D mutations in human plasma retinol-binding protein.

Retinol-binding protein (RBP) is the retinol-specific carrier protein present in plasma, where it circulates almost entirely bound to thyroxine-binding transthyretin (TTR). Recently, depressed plasma retinol and RBP levels in carriers of the I41N and G75D RBP point mutations have been reported. We show here that although recombinant human N41 and D75 RBPs can form complexes with retinol and TTR in vitro, the retinol-mutated RBP complexes are significantly less stable than human normal holo-RBP, as revealed by the markedly facilitated retinol release by mutated holo-RBPs to phospholipid membranes, in accordance with the location of mutated residues inside the RBP retinol-binding cavity.
