Tranexamic Acid Treatment Reduces Blood Loss After Elective and Semi-Urgent Reverse Total Shoulder Arthroplasty.

Introduction: Post operative blood loss after reverse shoulder arthroplasty (RSA) is associated with the need for blood transfusion and prolonged hospital stay, among other complications. Tranexamic acid (TXA) reduces perioperative blood loss and is effective when delivered systemically or locally. We compared the effects of TXA on perioperative blood loss between elective and semi-urgent RSA.

At long-term follow-up many first-time male traumatic shoulder dislocators remain symptomatic.

Objectives: To assess the status at 13 to 17 years follow-up of a cohort of young male traumatic shoulder dislocators.

Study Design: Prospective cohort study.

Methods: A prospective study of first-time young male traumatic shoulder dislocators, began in 2004.

The effect of steroid injection into the shoulder on glycemia in patients with type 2 diabetes.

Background: Injections of corticosteroids into or around joints have been reported to increase blood glucose in patients with diabetes due to corticosteroid absorption into the bloodstream. However, the magnitude, duration, and clinical implications of local corticosteroid injections on glycemic control are not clear. The purpose of this study was to evaluate the effects of corticosteroid injection to the shoulder on glycemia in patients with type 2 diabetes mellitus using a continuous glucose monitoring device.

Combined Bankart and SLAP repair: patient-reported outcome measurements after a minimum 5-year follow-up.

Background: Anterior shoulder instability is typically characterized by detachment of the anteroinferior labrum (Bankart lesion). Some patients also sustain a superior labrum anterior-to-posterior (SLAP) injury. The purpose of this study was to compare the medium-term clinical results of isolated anterior Bankart repairs (ABR) with those of combined Bankart and SLAP repair (ABR + SLAP).

Significance of tibial MRI findings of special forces recruits at the onset of their training.

Introduction: MRI is commonly used to evaluate medial tibial stress syndrome (MTSS), based on grading assessments developed in civilian populations. When MTSS represents stress fracture, rest is required to allow for bone remodelling to occur. False positive evaluations can lead to unnecessary recruit attrition.

Hyaluronic acid injections for chronic tennis elbow.

Background: For most patients, tennis elbow (TE) resolves within 6 months of onset. For those with persistent and painful TE, nonsurgical treatment options are limited. Thousands of studies have tried to find effective treatments for TE but have usually failed.

MTADV 5-MER peptide suppresses chronic inflammations as well as autoimmune pathologies and unveils a new potential target-Serum Amyloid A.

Despite the existence of potent anti-inflammatory biological drugs e.g., anti-TNF and anti IL-6 receptor antibodies, for treating chronic inflammatory and autoimmune diseases, these are costly and not specific.

A Multicenter Retrospective Study With a Minimum 5-Year Follow-up Comparing Arthroscopic Bankart Repair and the Latarjet Procedure.

Background: Arthroscopic Bankart repair (ABR) and the Latarjet procedure are surgical techniques commonly used to treat anterior shoulder instability. There is no consensus among shoulder surgeons regarding the indications for choosing one over the other.

Purpose: To compare the results of the Latarjet procedure with those of ABR for the treatment of anterior shoulder instability.

Friedrich Disease: A Case Report.

Case: A 16-year-old girl presented with pain and swelling of the medial edge of the clavicle. She denied previous trauma and was evaluated by multiple physicians for a possible infection or neoplastic lesion. The patient underwent multiple studies and procedures, including blood tests, imaging studies, and biopsy.

Combined bacteriophages and antibiotics as an efficient therapy against VRE Enterococcus faecalis in a mouse model.

Clinical applications of bacteriophage therapy have been recently gathering significant attention worldwide, used mostly as rescue therapy in cases of near-fatal antibiotic failure. Thus, clinically relevant in-vivo models presenting both short- and long-term implications of phage therapy given as rescue treatment for fulminant infections are of highest importance. In this study, a cocktail consisting of two lytic bacteriophages was used to evaluate the therapeutic efficacy of phage therapy as a rescue treatment for severe septic peritonitis in a mouse model.

[FROM THE LAB BENCH TO THE PATIENT - CAN INJURED SKELETAL TISSUES REGENERATE?].

Regenerative medicine research has evolved significantly in recent years. There is a great un-met clinical need for developing new treatments that will induce regeneration of injured skeletal tissues in cases such as large bony defects caused by trauma or tumor resection, articular cartilage defects and torn or degenerate tendons and ligaments. Except for bone that can regenerate small defects, all other skeletal tissues do not hold the natural capability for regeneration after injury and rather form a less functional scar tissue.

Biceps Tenotomy Does not Affect the Functional Outcomes of Patients Treated with Spacer Implantation Due to Massive Irreparable Rotator Cuff Tears.

Background: Lesions of the long head of the biceps (LHB) tendon are frequently associated with massive rotator cuff tears (RCT) and may be responsible for shoulder pain and disability.

Objective: This study aimed to evaluate functional outcomes of arthroscopic biodegradable spacer implantation with or without biceps tenotomy as treatment for persistent shoulder dysfunction and pain due to a massive irreparable RCT.

Methods: A total of 48 patients were implanted with the subacromial spacer using arthroscopic approach with or without biceps tenotomy.

Should Patients With Frozen Shoulder Be Screened for Diabetes Mellitus?

Background: Idiopathic frozen shoulder (nontraumatic) is commonly encountered in patients between the ages of 35 and 60 years in general orthopaedic practice. While the prevalence of frozen shoulder among the general population is estimated to be between 2% and 4%, a significantly higher prevalence of 10% to 22% has been reported in patients with diabetes mellitus. Since diabetic patients are more prone to develop frozen shoulder than nondiabetics, the question arises as to whether patients diagnosed as having idiopathic frozen shoulder are at greater risk to develop diabetes mellitus and should be routinely screened for this condition.

Phage Therapy: A New Horizon in the Antibacterial Treatment of Oral Pathogens.

Dental diseases are perhaps the most prevalent infection-related diseases in humans. Biofilm is involved in almost every infectious disease compromising oral health, notably caries, periodontal disease, gingivitis, endodontic infections and peri-implantitis. Current therapies of biofilm-derived oral infections lack sensitivity; they are not species-specific and kill pathogenic species as well as commensal species, which are protective against the formation of pathogenic biofilms.

Phage therapy against Enterococcus faecalis in dental root canals.

Antibiotic resistance is an ever-growing problem faced by all major sectors of health care, including dentistry. Recurrent infections related to multidrug-resistant bacteria such as methicillin-resistant Staphylococcus aureus, carbapenem-resistant Enterobacteriaceae, and vancomycin-resistant enterococci (VRE) in hospitals are untreatable and question the effectiveness of notable drugs. Two major reasons for these recurrent infections are acquired antibiotic resistance genes and biofilm formation.

Sustained Release of Antibacterial Lipopeptides from Biodegradable Polymers against Oral Pathogens.

The development of antibacterial drugs to overcome various pathogenic species, which inhabit the oral cavity, faces several challenges, such as salivary flow and enzymatic activity that restrict dosage retention. Owing to their amphipathic nature, antimicrobial peptides (AMPs) serve as the first line of defense of the innate immune system. The ability to synthesize different types of AMPs enables exploitation of their advantages as alternatives to antibiotics.

Synovial Lipomatosis of the Glenohumeral Joint.

Synovial lipomatosis (also known as lipoma arborescens) is a rare and benign lesion affecting synovium-lined cavities. It is characterized by hyperplasia of mature fat tissue in the subsynovial layer. Although the most commonly affected site is the knee joint, rarely additional locations such as tendon sheath and other joints are involved.

Cigarette Smoking Is Associated with a Lower Concentration of CD105(+) Bone Marrow Progenitor Cells.

Cigarette smoking is associated with musculoskeletal degenerative disorders, delayed fracture healing, and nonunion. Bone marrow progenitor cells (BMPCs), known to express CD105, are important in local trophic and immunomodulatory activity and central to musculoskeletal healing/regeneration. We hypothesized that smoking is associated with lower levels of BMPC.

Evidence for the adverse effect of starvation on bone quality: a review of the literature.

Malnutrition and starvation's possible adverse impacts on bone health and bone quality first came into the spotlight after the horrors of the Holocaust and the ghettos of World War II. Famine and food restrictions led to a mean caloric intake of 200-800 calories a day in the ghettos and concentration camps, resulting in catabolysis and starvation of the inhabitants and prisoners. Severely increased risks of fracture, poor bone mineral density, and decreased cortical strength were noted in several case series and descriptive reports addressing the medical issues of these individuals.

Targeting Enterococcus faecalis biofilms with phage therapy.

Phage therapy has been proven to be more effective, in some cases, than conventional antibiotics, especially regarding multidrug-resistant biofilm infections. The objective here was to isolate an anti-Enterococcus faecalis bacteriophage and to evaluate its efficacy against planktonic and biofilm cultures. E.

The supine apprehension test helps predict the risk of recurrent instability after a first-time anterior shoulder dislocation.

Background: We previously identified the positive result of the supine apprehension test after completion of rehabilitation following a first dislocation as a possible predictor of high risk for redislocation. We extend the follow-up of a previous cohort of patients with first-time shoulder dislocations to better assess this test.

Methods: Fifty-three men aged 17 to 27 years who sustained a first traumatic shoulder dislocation were treated by shoulder immobilization for 4 weeks and then rehabilitated with a standard physical therapy protocol.
