In covering wounds, efforts should include use of the safest and least invasive methods with a goal of achieving optimal functional and cosmetic outcome. The recent development of advanced technology in wound healing has triggered the use of cells and/or biological dermis to improve wound healing conditions. The purpose of the study was to evaluate the effects of fibroblast-seeded artificial dermis on wound healing efficacy.Ten nude mice were used in this study. Four full-thickness 6-mm punch wounds were created on the dorsal surface of each mouse (total, 40 wounds). The wounds were randomly assigned to one of the following 4 treatments: topical application of Dulbecco phosphate-buffered saline (control), human fibroblasts (FB), artificial dermis (AD), and human fibroblast-seeded artificial dermis (AD with FB). On the 14th day after treatment, wound healing rate and wound contraction, which are the 2 main factors determining wound healing efficacy, were evaluated using a stereoimage optical topometer system, histomorphological analysis, and immunohistochemistry.The results of the stereoimage optical topometer system demonstrated that the FB group did not have significant influence on wound healing rate and wound contraction. The AD group showed reduced wound contraction, but wound healing was delayed. The AD with FB group showed decreased wound contraction without significantly delayed wound healing. Histomorphological analysis exhibited that more normal skin structure was regenerated in the AD with FB group. Immunohistochemistry demonstrated that the AD group and the AD with FB group produced less α-smooth muscle actin than the control group, but this was not shown in the FB group.Fibroblast-seeded artificial dermis may minimize wound contraction without significantly delaying wound healing in the treatment of skin and soft tissue defects.

Anterior cervical osteophytes are commonly found in elderly patients, but rarely produce symptoms. When symptoms occur, they can range from mild symptoms of dysphagia, dysphonia, and foreign body sensation to severe symptoms of airway obstruction due to compression of the pharynx or larynx. We report the case of a 59-year-old man who underwent brain tumor surgery, and developed post-operative respiratory difficulty due to progressive pharyngo-laryngeal edema, requiring urgent endotracheal intubation, secondary to the presence of a previously asymptomatic anterior cervical osteophyte. It is paramount to recognize that asymptomatic anterior cervical osteophytes are a potential cause of life-threatening post-operative respiratory complications that can rapidly progress to life-threatening airway obstruction after surgeries in the prone position, especially in elderly patients.

Most women with asymmetric pectus excavatum suffer from hypoplastic breasts. Hence, aesthetic correction of pectus excavatum has to address thoracic wall deformity, breast hypoplasia, and asymmetry.In retrospective series, 21 patients with a diagnosis of pectus excavatum with hypoplastic breasts were corrected using the pectus bar procedure and subpectoral augmentation mammoplasty. Results were assessed by analyzing prospectively collected data and calculating pectus indices from computed tomographic scans. At 12 months postoperatively, cosmetic evaluations were performed by the patients and by an independent, board-certified plastic surgeon using score from 0 (very poor) to 4 (very good).Cosmetic results evaluated by plastic surgeon were good (3.33 ± 0.03) and patient satisfaction was high (3.52 ± 0.03). Furthermore, indices of pectus excavatum were corrected to near normal.The authors consider that the pectus bar procedure with subpectoral augmentation mammoplasty is useful for the aesthetic correction of pectus excavatum with hypoplastic breasts.
