Several alloplastic biomaterials are available for injection to the breast, nevertheless not all of them are approved for biomedical use. Although in North America and Western Europe experience with synthetic biomaterials for breast augmentation is very limited, migratory streams might expose physicians worldwide to manage the related complications...

The objectives of abdominal hernia repair are to restore the structural integrity of the abdominal wall. Current techniques include primary closure, staged repair and the use of prosthetic materials. Techniques for mini-abdominoplasty include the use of the transverse lower abdominal incision and the resection of excess skin. We report a case of ep...

Background: Because the ischial region is the main weight-bearing area in sitting, it is one of the areas most frequently affected by pressure ulcers in paraplegic patients resuming the sitting position during the subacute and chronic stages. The techniques described to date have not been able to reduce the high rates of recurrence and flap dehisc...

The exposure of bone, tendons, vessels, and nerves in a digital defect is one of the most frequent and severe problems to solve in hand surgery and current approaches are still disappointing. We show the use of an homodigital adipofascial flap taken from the same finger for covering the pulpar defect in a one-step surgical technique able to preserv...

To date silicone gel and silicone occlusive plates are the most useful and effective treatment options for hypertrophic scars (surgical and traumatic). Use of silicone sheeting has also been demonstrated to be effective in the treatment of minor keloids in association with corticosteroid intralesional infiltration. In our practice, we encountered f...

Keloids and hypertrophic scars are abnormal responses to wound healing. In general, keloids exhibit a proliferative growth beyond the margins of the scar and remain persistent; while hypertrophic scars are contained to the original wound and may regress over time. In particular, keloid formation is one of the most challenging clinical problems, wit...

Gluteal augmentation with autologous fat is becoming a standard ancillary procedure for sculpting the buttock area. The high rate of resorption due to aggressive harvesting techniques or inadequate injection procedures often leads to repeated treatments. Currently, several techniques for storing fat by controlled freezing and thawing procedures can...

The role of surgically removing subcutaneous fat by abdominoplasty on circulating inflammatory markers and myocardial dysfunction, evaluated by myocardial performance index (MPI), were investigated. Twenty volunteers submitted to the abdominoplasty (abdominoplasty group), and other 28 women treated by hypocaloric diet (diet group) were evaluated. E...

Hypertrophic scar (HS) and keloid (KL) are two forms of an abnormal cutaneous scarring process, mainly characterized by excessive extracellular matrix deposition and fibroblast proliferation. Despite the increased understanding of the molecular and cellular events leading to HS and KL, the pathogenesis of these lesions remains poorly understood. A...

Periprosthetic capsular contracture represents a specific iatrogenic phenomenon with different side effects. Recently, interesting data have disclosed a potential role of leukotrienes as important mediators of inflammation in the reactivation process of capsular contracture. Some preliminary studies have assessed the efficacy of leukotriene antagon...

Actually silicone gel and silicone occlusive sheeting are the most useful and effective treatment for hypertrophic scars, surgical and traumatic. Moreover it was recommended also in the treatment of minor keloid in association with corticosteroid intralesional infiltration. Unfortunately, we incurred in some problems: maceration, rashes, itching an...

The development of a fibrotic capsule around foreign material in the body is a physiologic reaction undertaken by the body to protect itself from a material it does not recognize. The periprosthetic capsule can pathologically contract, pressing on the implant; it can cause pain, firmness, and sometimes implant extrusion. The pathogenesis of capsula...

Adipose tissue is a metabolically active tissue. The hypertrophic fat cells of obese patients produce increased quantities of leptin and tumor necrosis factor-alpha (TNF-alpha) and are less sensitive to insulin. This study aimed to determine whether aspirating large amounts of these subcutaneous fat cells by large-volume liposuction (LVL), could ch...

Obesity is a major risk factor for coronary heart disease, and surgical treatment of obese patients as part of a multidisciplinary approach seems to provide faster results than diet therapy. The aim of this study was to evaluate the effect of dermolipectomy on insulin action and inflammatory markers in 20 obese women. At baseline and 40 days after...

The results obtained with a technique using the dermis suspension associated with a central pedicled dermo-glandular-adipose flap, for the durable filling of the superior pole over time, are presented. Forty patients, affected by marked mammary hypertrophy, have been selected and divided into 2 groups (A, B) of 20 patients each. In both groups we h...

During surgical procedures, coagulation complications may occur. Discriminating factors are multiple and may vary because of the anatomical regions involved and because of preexisting diseases. The aim of this study was to analyze changes in such hematological parameters of patients undergoing conventional abdominoplasty with standard surgical proc...

The finding of an untreated omphalocele in adulthood is extremely rare. We report the case of a 29-year-old patient, who presented to us with a congenital defect of the abdominal wall and protrusion of underlying viscera.
