We present a new reconstructive system encompassing prostheses and fat grafting as integrated tools to improve the final reconstructive outcome. Fat grafting in our view is a pre-operatively planned part of the reconstruction. The final volume we achieve will be made up of fat and implants in a variable percentage according to patient's body contour and breast morphology. We used the "Hybrid Breast Recontruction" technique in more than 350 reconstructions, both immediate and delayed, two-stage and DTI, without experiencing higher loco-regional recurrence and complication rates when compared with conventional two-stage reconstructions, obtaining excellent aesthetic results and high patients' satisfaction levels...

The bilateral V-Y flap concept for fingertip reconstruction was first desribed by Kutler. This method has limitations, such as flap size and advancement, therefore larger flap modifications are described to increase the advancement capacity of the flaps. We described a small direct-flow homodigital island flap method, called the 'super Kutler flap', for recontruction of finger pulp defects. In addition, neurorrhaphy was performed between the cut ends of the digital nerves to prevent neuroma formation. This method was used in 10 fingers in patients who had undergone pulp tissue reconstruction of fingertip defects from May 2008 to October 2011...

Bacterial biofilms play key roles in environmental and biomedical processes, and understanding their activities requires comprehension of their nanoarchitectural characteristics. Electron microscopy (EM) is an essential tool for nanostructural analysis, but conventional EM methods are limited in that they either provide topographical information alone, or are suitable for imaging only relatively thin (<300 nm) sample volumes. For biofilm investigations, these are significant restrictions. Understanding structural relations between cells requires imaging of a sample volume sufficiently large to encompass multiple cells and the capture of both external and internal details of cell structure...

BACKGROUND: Instability of the sternoclavicular joint is a very uncommon disorder of the shoulder girdle. Acute traumatic dislocations are commonly treated nonoperatively. But severe displacement or chronic instability with recurrent symptomatic subluxation may require surgical intervention. We present our results with open reduction and internal fixation through an autologous gracilis tendon transplant or fiber tape in 8 patients treated surgically. The operative stabilisation of the sternoclavicular joint reduces pain level and improves function of the shoulder...

BACKGROUND: After a review of clinical cases of the Unit of Plastic Surgery of the University of Siena, Italy, we found that 22 patients undergoing lipofilling for breast recontruction needed less pain drugs compared to 18 patients which did not undergo lipofilling. In this work, the postoperative pain was analyzed in two groups of patients: a cohort treated with prosthesis and a cohort treated with prosthesis implant together with a lipofilling procedure. PATIENTS AND METHODS: During the immediate postoperative period, a visual analog scale for pain was submitted to every patient every eight hours until they were discharged, then every day for a week, every two days during the second week and once a week in the first three months...

Myosin interacting-heads (MIH) motifs are visualized in 3D-reconstructions of thick filaments from striated muscle. These reconstructions are calculated by averaging methods using images from electron micrographs of grids prepared using numerous filament preparations. Here we propose an alternative method to calculate the 3D-reconstruction of a single thick filament using only a tilt series images recorded by electron tomography. Relaxed thick filaments, prepared from tarantula leg muscle homogenates, were negatively stained...

A widening spectrum of increasingly advanced bronchoscopic techniques is available for the diagnosis and treatment of various bronchopulmonary diseases. The evolution of computed tomography (CT)-multidetector CT in particular-has paralleled these advances. The resulting development of two-dimensional and three-dimensional (3D) postprocessing techniques has complemented axial CT interpretation in providing more anatomically familiar information to the pulmonologist. Two-dimensional techniques such as multiplanar recontructions and 3D techniques such as virtual bronchoscopy can provide accurate guidance for increasing yield in transbronchial needle aspiration and transbronchial biopsy of mediastinal and hilar lymph nodes...

BACKGROUND: The trehalose synthetic pathway is present in bacteria, fungi, plants and invertebrate animals, but is absent in vertebrates. This disaccharide mainly functions as a stress protectant against desiccation, heat, cold and oxidation. Genes involved in trehalose synthesis have been observed in apicomplexan parasites, but little was known about these enzymes. Study on trehalose synthesis in apicomplexans would not only shed new light into the evolution of this pathway, but also provide data for exploring this pathway as novel drug target...

BACKGROUND: In cholesteatoma surgery the use of autogenous ossicles for restoration of sound conduction is often limited because of ingrowth of matrix epithelia into the ossicular bone. In an attempt to eliminated these epithelial cells we tested extracorporal high-pressure hydrostatic treatment as a new method for devitalizing the bone but maintaining its structure. METHODS: The inpact of different high hydrostatic pressures either on single cell suspensions of fibroblasts and osteoblasts, or on cells in ex-vivo ossicles chain was examined with different methods (quantitative proceedings, live/dead assay)...
