Abdominoplasty provides a reconstructive but rarely aesthetic cosmetic solution after major weight loss. Few articles document quality of life (QOL) issues and the psychological impact of abdominoplasty on obese patients. We report a retrospective study of 41 abdominoplasties performed after an average weight loss of 40.2 kg. Data were obtained through review of patient medical files, double-blind surgical and psychological examinations, and two specifically designated questionnaires used to assess pre-abdominoplasty body perception and QOL, post-body contouring perception of improvement, and psychological status. To date, 14 patients have regained >10 kg; 84.6% have improved QOL; 86.5% have improved psychological status; 74% have better sexual relations; 53.9% admit liking their body; 76.9% are satisfied with the results of abdominoplasty; and 96.1% would be willing to undergo abdominoplasty again. Anterior dermolipectomy improves both QOL and psychological status. Provision of patient education, multidisciplinary management, and long-term follow up are necessary to obtain satisfactory results.
Introduction Rheumatoid arthritis (RA) is a heterogeneous disease and its underlying molecular mechanisms are still poorly understood. Because previous microarray studies have only focused on long-standing (LS) RA compared to osteoarthritis, we aimed to compare the molecular profiles of early and LS RA versus control synovia.
Our quantitative values concerning the skin paddle related to the perforator arteries may be of significant interest to the surgeon who aims to harvest a composite musculocutaneous gracilis flap, in order to improve its reliability by reducing the risk of cutaneous necrosis.
Mastocytosis is a group of disorders characterized by abnormal mast cell proliferation, involving the skin in 80% of cases. Cutaneous mastocytosis, which appears in childhood in 60% of cases, usually has a benign course with a gradually regressive evolution before puberty. Mast cell sarcomas, part of the systemic forms of mastocytosis, are very rare tumors characterized by a destructive growth of highly atypical mast cells, with secondary spread, poor prognosis, and low survival rates. We report the first known case of primary cutaneous mast cell sarcoma due to the transformation of a benign solitary mastocytoma in an adult suffering from an unregressive localized cutaneous mastocytosis. Histologic characteristics of the tumor, mutation analysis, and c-Kit expression were compared with available data. Wide surgical excision of the tumor followed by adjuvant local radiotherapy were performed, and for the first time the use of imatinib was attempted, as neoplastic mast cells expressed the CD117 marker. However, they failed to control the progression of sarcoma. To date, no treatment is known to be effective for this disease, which is associated with short-term survival of the patients.
Several flaps have been described to treat severe soft tissue defects of the finger dorsal side. Many authors studied vascular organization of the hand on its dorsal side; most of them insisted on deep vascularization into the intermetacarpal spaces, which is formed by the dorsal metacarpal arteries. Those dorsal metacarpal arteries are the anatomical support of many flaps, which do not preserve the dorsal interosseous muscles fascias. Only few authors described dorsal vascular organization at the level of the proximal phalanx; however, using a rotation point of a flap distally to the metacarpal head with a donor site on the dorsal aspect of the hand could cover all distal soft tissue defect of long finger. In order to determine the technical limitations of dorsal digito-metacarpal flap procedures, we studied number and location of arterial anastomoses between the reticular subcutaneous dorsal network and the rest of the vascularization at this level, which was formed by the deeper dorsal metacarpal arteries, common palmar digital arteries and proper palmar digital arteries, and between the dorsal digital arteries. Twenty-four long fingers from embalmed cadavers were studied after a reverse flow injection of colored latex and dissected layer-by-layer preserving the digital-metacarpal arterial network. At the level of the hand, the dorsal metacarpal arteries of the third and fourth intermetacarpal spaces were inconstant. When present, two or three arteries anastomosed in star shape with the reticular network. No such arterial anastomosis was observed proximally to the level of the intertendinous connections (junctura tendinorum) that bridge the extensor digitorum communis tendons. When no dorsal metacarpal artery was present, some communicant arteries arose from the common palmar digital arteries. Moreover, all the nutrient branches were more numerous distally to the intertendinous connections (junctura tendinorum). At the level of the metacarpophalangeal joints, the hand cutaneous network was always anastomosed with the dorsal cutaneous network. At the level of fingers, the dorsal cutaneous network was always supplied by four branches arising from the proper digital artery. Our study supported the reliability of dorsal digitometacarpal flaps, supplied by numerous palmodorsal digital anastomoses and by a rich plexiforme network joining the hand skin supply and that of the dorsal finger skin. During the procedure, we recommend limiting the surgical dissection of the flap at the level of the middle phalanx.
Adipose tissue is an abundant source of various cell types including not only adipocytes, but also progenitor and endothelial cells from thestroma. Interest in adipose tissue has surged since the identification in 2001 of adipose-derived stem cells (ADSCs) and of the stromal vascular fraction (SVF) obtained from adipose tissue by enzymatic digestion and centrifugation. SVF has been proven effective in ensuring tissue regeneration, thus improving tissue trophicityand vascularisation. These effects have generated strong interest among both physicians and surgeons, particularly in the field of hand surgery. Several applications have been developed and used, for instance to treat Dupuytren's contracture, systemic sclerosis-related hand lesions, and skin ageing at the hand. Other uses are being evaluated in clinical or animal studies. The objective of this article is to review the capabilities of adipose tissue and their current and potential applications in hand surgery.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
