OBJECTIVES To compare the long-term results of stripping vs. haemodynamic correction (Ambulatory Conservative Haemodynamic Management of Varicose Veins, CHIVA) in the treatment of superficial venous incompetence resulting in chronic venous disease (CVD). DESIGN Randomised comparative trial. PATIENTS 150 patients affected by CVD, CEAP clinical class 2-6, were randomised to saphenous strippin...

Liquid membranes usually consist of an extracting agent (carrier) in an organic solvent which separates "feed" and "stripping" phases containing aqueous solutions of the solute of interest and a stripping agent, respectively. In supported liquid membranes (SLMs) the membrane solution is immobilised into a thin solid microporous support, between the feed and stripping phases where transport is f...

Primary tumors of scapula are rare. The majority of them have a cartilaginous origin, being the most frequent the osteochondroma, followed by the chondrosarcoma. In this article we will review the main features of the osteochondroma and another rare tumor, the periosteal chondroma, from which there are very few cases reported in the literature. After reviewing the main features of both tumors, ...

Periosteal osteoid osteoma is extremely rare. The diagnosis is not always clear. We report a case of periosteal osteoid osteoma arising from the posterior surface of the right distal femur in a 21-year-old woman. After careful evaluation and excisional biopsy, histological examination confirmed the diagnosis of osteoid osteoma, showing the nidus, surrounding osteosclerosis, and catarrhal synovi...

In the last 10 years, traumatologists have become more aware of the importance of blood supply to fracture fragments for both the healing of fractures and prevention of infection. Due to our experience with fractures having severely disrupted periosteal blood supply, we are looking more critically at intramedullary reamed nailing as a treatment option. This research was a result of our increase...

The influence of nanoparticle aggregation on anodic stripping voltammetry is reported. Dopamine-capped silver nanoparticles were chosen as a model system, and melamine was used to induce aggregation in the nanoparticles. Through the anodic stripping of the silver nanoparticles that were aggregated to different extents, it was found that the peak area of the oxidative signal corresponding to the...

INTRODUCTION Orthopaedic fracture fixation plates are applied using metal bone screws. Surgeons do this manually by “feel” without monitoring the torque applied. Few studies have measured the stripping torque of bone screws in human bone [1-3]. No studies have measured stripping torque in the synthetic bones increasingly being used in biomechanical studies. The present aim was to measure stripp...

Osteointegration is a direct structural relationship between the bone and implant surface, properly osseointegration can function without mobility. We aim to evaluate this process using serial radiological examinations, where characteristics such as sclerosis cortical-periosteal thickening will be investigated. A retrospective analytic-observational study was conducted on 96 patients after ceme...

OBJECTIVE The objective of this randomized study was to compare the efficacy of the CHIVA method for the treatment of varicose veins with respect to the standard treatment of stripping. CONTEXT Varicose veins are a sign of chronic venous disorder. For over a century, varicose veins have been treated with surgical ablative techniques, with stripping being the standard treatment. Currently, pos...
