Assessment of Thermal Influence on an Orthodontic System by Means of the Finite Element Method.

The development of the finite element method (FEM) combined block polynomial interpolation with the concepts of finite difference formats and the variation principle. Because of this combination, the FEM overcomes the shortcomings of traditional variation methods while maintaining the benefits of current variation methods and the flexibility of the finite difference method. As a result, the FEM is an advancement above the traditional variation methods.

Nasal polyposis from cystic fibrosis in children - the experience of a single center.

Background: Cystic fibrosis (CF) is the most common monogenic disease, characterized by clinically notable polymorphism. Respiratory disease is the main factor that influences the disease outcome and prognosis of the patient with CF, bacterial infections being responsible for severe exacerbations and rhinosinusitis a difficult complication, besides lung disease.

Aim: The aim of the paper was to present a case series of CF-associated nasal polyposis and our management experience, providing new data for nasal and sinus complications.

An Experimental and Virtual Approach to Hip Revision Prostheses.

(1) Introduction: The changes in the joint morphology inevitably lead to prosthesis, but the hip pathology is complex. The hip arthroplasty is a therapeutic solution and can be caused, most frequently, by primary and secondary coxarthrosis due to or followed by traumatic conditions. The main aim of this study was to find the method of revision hip prosthesis that preserves as much bone material as possible and has sufficiently good mechanical strength.

Case Presentation of Soft Tissue Defect after Bimalleolar Fracture Osteosynthesis.

A 59-year-old patient presented in the ER with wound dehiscence and skin necrosis on the right ankle, with osteosynthesis implant visible, after open reduction and fixation with plate and screws, performed abroad, 16 days prior to the presentation, for a bimalleolar fracture. The patient was admitted to the plastic surgery department, where surgical debridement of the necrotic tissue was initially performed. Postoperatively, the patient was treated with Negative-pressure wound therapy (VAC dressing) and Platelet rich plasma (PRP) therapy.
