Biomechanical Evaluation of Posterior Shoulder Instability With a Clinically Relevant Posterior Glenoid Bone Loss Model.

Background: Existing biomechanical studies of posterior glenoid bone loss and labral pathology are limited by their use of anterior instability models, which differ in both orientation and morphology and have been performed in only a single, neutral arm position.

Purpose: To evaluate the biomechanical effectiveness of a posterior labral repair in the setting of a clinically relevant posterior bone loss model in various at-risk arm positions.

Study Design: Controlled laboratory study.

Effects of Lateral Opening-Wedge Distal Femoral Osteotomy on Meniscal Allograft Transplantation: A Biomechanical Evaluation.

Background: Lateral meniscal deficiency with valgus malalignment increases the rate of lateral compartment osteoarthritis. Lateral meniscal allograft transplantation (LMAT) with a concomitant varus-producing opening-wedge distal femoral osteotomy (DFO) is an option yet to be evaluated biomechanically.

Purpose/hypothesis: The purpose of this study was to clarify the biomechanical effects of the realignment procedure in the setting of LMAT.

Preventing varus collapse in proximal humerus fracture fixation: 90-90 dual plating versus endosteal fibular allograft strut.

Introduction: Screw cut out and varus collapse are the most common complication of locked plate fixation of proximal humerus fractures. The purpose of this study was to compare dual plating and endosteal fibular allograft struts as augmentation strategies to prevent varus collapse.

Materials And Methods: A trapezoidal osteotomy was created at the metaphysis to create a 2-part proximal humerus model in 18 paired shoulder specimens.

Weight Loss in Patients Waiting for Total Hip Arthroplasty: Fiber-Enriched High Carbohydrate Diet Improves Hip Function and Decreases Pain before Surgery.

The impact of obesity on clinical outcomes following joint replacement procedures is resounding. Therefore, multiple strategies to achieve a substantial weight loss before surgery are needed in obese patients. The aim of the study was to test the effect of a fiber-enriched high carbohydrate (FEHC) diet on the reduction in body weight and pain in elderly obese patients undergoing total hip arthroplasty (THA).

The relationship between fluid biomarkers and clinical outcomes in sports-related concussions: a systematic review.

Objectives: The literature on fluid biomarkers for concussion has primarily focused on comparing athletes with and without a diagnosis of concussion and on examining the relationship between fluid biomarkers and exposure to head trauma. This systematic literature review aims to examine the strength of evidence for fluid biomarkers to be associated with clinically relevant outcomes in sports-related concussion.

Methods: A systematic literature review was conducted using EmBASE, PubMed, and CINAHL.

[Fetoscopic laser coagulation in 100 consecutive monochorionic pregnancies with severe twin-to-twin transfusion syndrome].

Objectives: To report pre- and post-surgical datas of large series of severe twin-to-twin transfusion syndrome (TTTS) managed with laser ablation surgery in our centre, to evaluate the incidence of complications, perinatal outcome and to compare with other cohorts.

Patients And Methods: Observational study of 100 cases of TTTS consecutively treated with fetoscopic laser coagulation between January 2004 and April 2010 in CMCO-SIHCUS of Schiltigheim.

Results: There are nine stage I, 49 stage II, 38 stage III and four stage 4.

Pseudoischemic electrocardiogram in myasthenia gravis with thymoma: reversibility after thymectomy.

Abnormal ST T-wave changes can be found at presentation in various noncoronary disorders; misinterpretation of these patterns as ischemic heart disease can lead to erroneous diagnosis and treatment. Here we present a case of myasthenia gravis (MG) with thymoma, in which the resting electrocardiogram (ECG) led to a misleading diagnosis of myocardial ischemia. After thymectomy, the ECG resumed a normal pattern.

In-hospital mortality and morbidity of elderly medical patients can be predicted at admission by the Modified Early Warning Score: a prospective study.

Objective: Although early warning scores were originally derived as bedside tools for alerting the medical staff, they may serve as decision rules for the admission of medical patients. We conducted this study to investigate the ability of the Modified Early Warning Score (MEWS) to identify a subset of patients at risk of deterioration, who might benefit from an increased level of attention.

Design: Prospective, single centre, cohort study.

A patient with loss of vision in the right eye and neurofibromatosis type 1.

Neurofibromatosis type 1 is a common autosomal dominant condition that affects about 1 in 5000 people. We describe a 75-year-old man who, in addition to many classic developmental changes of the disease in his skin, eyes and nervous system, had blindness in his right eye as a complication.

[An unusual case of pulmonary infiltrates with hepatic involvement in a woman with eosinophilia].

The literature reports many cases of eosinophilic pulmonary infiltrations, with different etiology. In our case clinical pictures were not very clear and specific at first and the clinical course was altered by an ex adjuvantibus steroid treatment before admission to hospital. It was new and unusual because it presented some characteristics of chronic eosinophilic pneumonia and idiopathic hypereosinophilic syndrome, with hepatic involvement as in the former, but without serious heart disease as in the latter.

[Pheochromocytoma and autoimmune hypothyroidism].

The association of multiple endocrine diseases is frequent and the coincidental involvement of the thyroid and adrenal glands is well recognized. On the contrary, two cases of hypo or hyperthyroidism have only been reported in literature: one concerning adrenal pheochromocytoma with simultaneous autoimmune hypothyroidism and another of a diffuse toxic goiter associated with pheochromocytoma. The purpose of the present report is to point out a new case of a pheochromocytoma associated with an autoimmune hypothyroidism in which the latter is florid and not biochemical.

Lithium-induced sinus node dysfunction.

A 74-year-old woman, on lithium carbonate treatment, developed symptomatic sinus node dysfunction and central nervous toxicity, which disappeared after discontinuation of the drug and when serum lithium fell from 2 to 1.27 mEq/L. Our review of the literature demonstrates that sinus node abnormalities can occur both in presence of therapeutic and toxic serum lithium levels and are frequently asymptomatic and completely reversible.

Free-cortisol assay by immunoextraction: comparison with an equilibrium dialysis procedure.

We describe a new method for directly determining the apparent free cortisol concentration in plasma samples by use of an antibody-coated test-tube RIA. Buffer-diluted plasma or standard serum is added to antibody-coated test tubes, incubated at 4 degrees C for 4 h, and the solutions are aspirated. 125I-labeled cortisol is added to each tube and incubated for 3 h at 4 degrees C.

Prenylamine-induced ventricular arrhythmias and syncopal attacks with Q-T prolongation. Report of a case and comment on therapeutic use of lignocaine.

A 70-year-old man, on prenylamine for exertional angina, complained of syncopal attacks which seemed to be caused by bursts of ventricular tachycardia associated with Q-T prolongation. These symptoms disappeared after treatment with lignocaine, and the Q-T interval gradually returned to normal when prenylamine was stopped. This communication emphasizes the possibility of the occurrence of Q-T prolongation with associated ventricular arrhythmias in patients treated with prenylamine and the usefulness of a cautious trial with lignocaine in ventricular arrhythmias linked to Q-T prolongation.
