Impact of Body Mass Index on the Accuracy of Physical Examination and MRI of the Shoulder.

Background: The physical examination of overweight patients can require specific adaptations. Orthopaedic literature on the impact of body mass index (BMI) on the physical examination of the shoulder is virtually nonexistent.

Purpose: To assess whether BMI affects the sensitivity and specificity of common shoulder tests, using arthroscopy as a gold standard.

Software simulations of changing offsets and thus soft tissue tension when revising anatomic to reverse total shoulder arthroplasty in convertible platform systems.

Background: Revision shoulder arthroplasty may involve the need to remove a well-fixed humeral stem. To avoid this, convertible platform systems have been introduced. The biomechanics of reverse total shoulder arthroplasty (rTSA) differs from anatomic shoulder arthroplasty (aTSA).

The "Parachute" Technique: A Simple and Effective Single-Row Procedure to Achieve an Increased Contact Area Between the Cuff-Tendon and Its Footprint.

Many techniques of arthroscopic rotator cuff repair have been described. No significant differences in clinical outcomes or rerupture rates have been observed when comparing single-row with double-row methods. Not all single- and double-row repairs are the same.

Recurrent rotator cuff tear: is ultrasound imaging reliable?

Background And Hypothesis: The diagnostic workup of the painful shoulder after rotator cuff repair (RCR) can be quite challenging. The aim of this study was to assess the reliability of ultrasonography (US) for the detection of recurrent rotator cuff tears in patients with shoulder pain after RCR. We hypothesized that US for the diagnosis of recurrent rotator cuff tear after RCR would not prove to be reliable when compared with surgical arthroscopic confirmation (gold standard).

The "Purse String" Procedure for Recurrent Anterior Glenohumeral Instability: A Simple Technique to Achieve Bankart Repair, Capsular Shift, and a Good Labral Bumper.

Failure of arthroscopic techniques in cases of recurrent anterior glenohumeral instability may result from inadequate treatment of capsular injury. The use of few anchors has been cited as a cause of failure in arthroscopic stabilization techniques. This applies to the use of the suture anchors as spot-welding points in conventional techniques.

Intraobserver and interobserver reliability of the Copeland-Levy classification for arthroscopic evaluation of subacromial impingement.

Background: Defining a simple and reliable classification for acromial and bursal impingement lesions is necessary to standardize terminology, to improve communication, and to allow better evaluation of the proper treatment of impingement lesions and rotator cuff tears. The purpose of this study was to assess orthopedic surgeons' intraobserver and interobserver reliability of the Copeland-Levy classification.

Methods: Six fellowship-trained orthopedic surgeons reviewed shoulder arthroscopy videos of 69 consecutive patients who underwent shoulder arthroscopy for rotator cuff tear repair or subacromial decompression.

Manipulation under anaesthetic for frozen shoulder using Codman's paradox: a safe and early return of function.

Purpose: Although previously frozen shoulder was thought to resolve by two to three years, recent studies demonstrated the symptoms can remain for much longer. Manipulation under anaesthetic (MUA) has been shown to be successful in relieving pain and restoring function. Yet, concerns have been raised regarding its safety and the risks of complications.

Proximal Femoral Shortening After Cephalomedullary Nail Insertion for Intertrochanteric Fractures.

Objective: To assess the incidence of proximal femoral shortening (PFS) and its effect on the patient outcomes when intertrochanteric fractures were treated with a cephalomedullary nail (CMN).

Design: Retrospective cohort study.

Settings: Level II trauma center.

[THE IMPACT OF A COMMUNITY INTERVENTION PROGRAM IN ISRAELI WORKSITES TO REDUCE THE RISK OF CARDIOVASCULAR DISEASES].

Introduction: Atherosclerosis is the main cause of cardiovascular (CV) morbidity and mortality in the western world. Detection and treatment of risk factors (such as hypertension, dyslipidemia and diabetes mellitus) reduce CV events. We have shown cost utility in reducing these CV risk factors in community clinics and community centers.

[THE ISRAELI RAT GENOME CENTER].

The Israeli Rat Genome Center, which is located at the Barzilai Medical Center Campus of the Faculty of Health Sciences of the Ben-Gurion University of the Negev in Ashkelon, was established to provide a repository of unique genetic strains of rats that were created in Israel and that simulate complex diseases. The Center incorporates models of: salt-sensitive hypertension (SBN/y and SBH/y rats), type 2 diabetes (CDr and CDs rats), combined hypertension and diabetes (CRDH) and additional genetic strains (transgenics, consomics, congenics). All these strains are available to researchers who are interested in the study of complex diseases, on the basis of collaboration.

[Medical research improves quality of care].

The Barzilai Medical Center has recently been designated as an Academic Medical Center. The challenge to become an academic center arose from the realization that the level and quality of care provided to patients are necessarily improved when clinical medicine is practiced in a teaching and research environment. Indeed, after years of close working ties between the Barzilai Medical Center in Ashkelon and the Ben-Gurion University of the Negev, the center officially became an Academic Medical Center and was recognized as one of the two leading clinical campuses of the Faculty of Health Sciences.

Radiographic templating of total hip arthroplasty for femoral neck fractures.

Purpose: The purpose of this study was to evaluate the use of pre-operative digital templating to minimize complications including limb length discrepancy (LLD), intraoperative fractures and early dislocations in patients with intracapsular femoral neck fractures.

Methods: We retrospectively compared 23 patients undergoing total hip arthroplasty (THA) for intracapsular femoral fractures with pre-operative digital templating and 48 patients without templating.

Results: The mean post-operative LLD was significantly lower in patients who had pre-operative templating than in the control group (6.

Revision shoulder arthroplasty from resurfacing to non-cemented short-stem reverse prosthesis.

Objective: To assess the surgical parameters and the clinical and radiological outcomes of revisions of resurfacing shoulder arthroplasty to non-cemented short-stem reverse total shoulder arthroplasty.

Material And Methods: A total of 23 revisions from resurfacing shoulder arthroplasty to reverse total shoulder arthroplasty were performed. The mean age was 70.

Macrophages dictate the progression and manifestation of hypertensive heart disease.

Background: Inflammation has been implicated in the initiation, progression and manifestation of hypertensive heart disease. We sought to determine the role of monocytes/macrophages in hypertension and pressure overload induced left ventricular (LV) remodeling.

Methods And Results: We used two models of LV hypertrophy (LVH).

Capsular closure does not affect development of heterotopic ossification after hip arthroscopy.

Purpose: The purpose of this study was to evaluate the role of capsular closure after hip arthroscopy in reduction of the incidence of heterotopic ossification (HO).

Methods: One hundred (50 study group, 50 control group) consecutive hip arthroscopy procedures with radiographic follow-up of more than 9 weeks were included in the study. The study group consisted of 50 patients in whom capsular closure with 2 No.

Reverse shoulder arthroplasty with a short metaphyseal humeral stem.

Purpose: Reverse shoulder prostheses have been gaining popularity in recent years. A short metaphyseal stem design will allow bone stock preservation and minimize stem related complications. We examined the clinical and radiographic short-term outcome of a short metaphyseal stem reverse shoulder arthroplasty.

Epidural hematoma secondary to sinusitis: a case report and review of the literature.

Epidural hematoma is a potentially life threatening event that demands prompt diagnosis and surgical treatment, usually following head trauma. We present a case of a 9-year-old boy with no history of head trauma, and who was diagnosed with epidural hematoma secondary to frontal sinusitis; and the medical literature was reviewed.

Unmasking of proteinuria in the course of genetic dissection of nonproteinuric diabetic nephropathy.

We previously described the development of nonproteinuric diabetic nephropathy (NPDN) in the Cohen diabetic rat (CDs), a model that simulates Type 2 diabetes in humans. Using linkage analysis in an F2 cross, we currently set out to investigate the mechanisms underlying NPDN. We crossbred between CDs and SBN/y, a nondiabetic rat strain, generated F1 and F2 progenies, fed them diabetogenic diet that elicits diabetes and NPDN in CDs but not in SBN/y, and determined metabolic and renal phenotypes.

Hemophagocytic lymphohistiocytosis associated with parechovirus 3 infection.

Hemophagocytic lymphohistiocytosis (HLH) denotes the common final pathway of a potentially fatal hyperinflammatory condition of diverse etiologies. We describe the first case of documented HLH associated with human parechovirus 3. A monoallelic Ala91Val mutation was found in the PRF1 gene, but the contribution of this mutation to HLH remains controversial.

Left atrial function during pregnancy: a three-dimensional echocardiographic study.

Background: Alteration of diastolic function is considered a sensitive means for detecting changes in the normal cardiac adaptation to pregnancy. Our aim was to evaluate volumetric and functional atrial parameters, using real time three-dimensional echocardiography (RT3DE) in women in early and late third trimester of pregnancy.

Methods: We studied pregnant women in early third trimester (III-E = gestational age 26-33 weeks), in late third trimester (III-L = gestational age 34-40 weeks), and control nonpregnant women (C).

Geno-transcriptomic dissection of proteinuria in the uninephrectomized rat uncovers a molecular complexity with sexual dimorphism.

Investigation of proteinuria, whose pathophysiology remains incompletely understood, is confounded by differences in the phenotype between males and females. We initiated a sex-specific geno-transcriptomic dissection of proteinuria in uninephrectomized male and female Sabra rats that spontaneously develop focal and segmental glomerulosclerosis, testing the hypothesis that different mechanisms might underlie the pathophysiology of proteinuria between the sexes. In the genomic arm, we scanned the genome of 136 male and 111 female uninephrectomized F2 populations derived from crosses between SBH/y and SBN/y.

Sex-specific genetic dissection of diabetes in a rodent model identifies Ica1 and Ndufa4 as major candidate genes.

The aim of the study was to initiate a sex-specific investigation of the molecular basis of diabetes, using a genomic approach in the Cohen Diabetic rat model of diet-induced Type 2 diabetes. We used an F2 population resulting from a cross between Cohen Diabetic susceptible (CDs) and resistant (CDr) and consisting of 132 males and 159 females to detect relevant QTLs by linkage and cosegregation analyses. To confirm the functional relevance of the QTL, we applied the "chromosome substitution" strategy.
