As it is more common to expose the body in certain cultures and in sunny countries such as Brazil, cellulite is of great concern to many women and also represents a problem of great social impact. In today’s globalized culture, physical well-being, including the care taken with appearance, is highly valued. From this perspective, it is very important to evaluate the impact on quality of life (QOL) of such cosmetic problems as cellulite, wrinkles, and aging. The fact that these have an impact on the QOL is indirectly shown by the growing interest in the investigation and treatment of these problems, which until recently were considered to be of minor significance. New studies involving QOL will benefit all those who suffer to a greater or lesser degree from these problems, and will be of great value in assessing the need for new scientific research into the treatment of these problems. Their study revealed that in the 37 different cultures studied, men and women gave greater priority to sexual attraction in the choice of partners than to aspects of personality such as independence, emotional stability, and maturity (1). Dermatological diseases and cosmetic problems significantly affect self-esteem. As the symp- toms are visible, the discomfort and psychoemotional effects are frequently more serious than the physical alterations caused by the disease. Thus, it becomes very important to assess and quantify the emotional and social parameters in these patients in order to understand the dis- ruption that the problem causes in various daily activities. Thiswill facilitate the follow-up and treatment evaluation, and consequently allow for improvements in the QOL of the patients. The great importance given to QOL evaluation in clinical investigation and patient care has led to the development of questionnaires designed for the collection of information from 1 2 & HEXSEL AND HEXSEL patients on the impact of the disease on their everyday lives. This knowledge allows the medi- cal professional to better observe how the disease affects the patients physically, psychologi- cally, and socially, and facilitates the evaluation of the effects on the lives of the patients. In the case of cellulite, the reasons that lead the patient to seek treatment are gener- ally social and, sometimes, also emotional. These may include the embarrassment caused by cellulite in social, affective, and sexual relations as well as the avoidance of normal everyday activities such as visiting a swimming pool or beach, practicing sports, or expos- ing the body during intimacy.

The primary goal of a bone graft material is to stabilize the periodontal defect buy 160mg diovan with visa, while promoting recovery of native bone cheap diovan 80mg visa. Engineering porosity into the degradable construct enhances cellular ingrowth and osteointegration within bone graft substitutes [28 buy generic diovan 40mg online,30–32] discount diovan 40mg with visa. Average pore sizes on the order of 150 to 500 m are desired for optimal bone cell ingrowth [33,34]. Bony ingrowth enables integration of the synthetic material within host tissue and promotes replace- ment of the degrading material with native bone. Porosity and mechanical properties of PPF composites as a function of material formulation were optimized for treatment of maxillofacial and mandibular defects. Formulation of the PPF-based bone graft substitutes enables easy application to osseous defects. Mixing of PPF and crosslinkers creates a putty that may be applied to defect sites and cured in situ. Viscosity of the resultant mixture permits injection through needles as small as 16 gauge. The set time of the material ranges from 1 to 10 min, during which time the material expands to fill void spaces and may be molded or placed by the surgeon. The crosslinking reaction is not highly exothermic, with temperatures between 37 and 40 C measured within the curing graft substitute. Highly exothermic reactions, such as those observed in PMMA bone cements, have been associated with local tissue necrosis. The PPF-based bone graft substitute approaches peak mechanical properties 18–24 h after application. Developing porosity of the cured graft substitute has been used to promote osteointegration and incorporation of the synthetic material. Engineered porosity of PPF-based bone graft substi- tutes has been created prior to implantation via a porogen leaching process. Controlled pore sizes are prepared by leaching porogen materials (either gelatin microspheres or salt particles like sodium chloride) from crosslinked PPF scaffolds [31,36]. Porous PPF scaffolds have also been produced using calcium carbonate and tricalcium phosphate as porogen fillers. These techniques are useful in engineering porosity in the scaffold as a function of particulate size and solubility. Generation of pores during the curing process was used as a method to induce immediate porosity and expansion of the graft substitute in situ. The addition of effervescent agents to the formulation controls expansion of the test material during curing. Expansion enables the material to intimately fill the defect site and creates pores that encourage tissue ingrowth. Porosity of the cured PPF composites was analyzed by scanning electron microscopy (SEM) (Fig. Tuning the concentration of effervescent agents—sodium bicarbonate (SB) and citric acid (CA)—effec- tively controls the porosity of the cured test material yielding average pore sizes ranging from 50 to 500 m. Porosity of the bone graft substitute promotes osteointegration and new bone formation within the graft substitute. Porosity of the PPF-based bone graft substitute affects the mechanical integrity of the material. Compressive mechanical properties were determined for highly porous, photocross- linked PPF scaffolds. Porosities greater than 80%, as produced by salt leaching, yielded a compressive strength of 0. The highly porous scaffolds had mechanical properties less than the average value for cancellous bone. Flexural properties of nonporous PPF and beta-tricalcium phosphate composite cylinders were evaluated using four-point bending.
