The psychological impact of immediate breast reconstruction for women with early breast cancer.

Twenty-five patients were evaluated, 13 who had immediate breast reconstruction and 12 who had delayed breast reconstruction for early breast cancer. Data were elicited about the psychological impact of the cancer, the mastectomy, and the reconstruction. Our results support the conclusion that immediate breast reconstruction is accompanied by a lower incidence of psychological morbidity postoperatively, and we recommend that immediate breast reconstruction be offered as an alternative to women with early breast cancer.

Memory regulatory T cells reside in human skin.

Regulatory T cells (Tregs), which are characterized by expression of the transcription factor Foxp3, are a dynamic and heterogeneous population of cells that control immune responses and prevent autoimmunity. We recently identified a subset of Tregs in murine skin with properties typical of memory cells and defined this population as memory Tregs (mTregs). Due to the importance of these cells in regulating tissue inflammation in mice, we analyzed this cell population in humans and found that almost all Tregs in normal skin had an activated memory phenotype. Compared with mTregs in peripheral blood, cutaneous mTregs had unique cell surface marker expression and cytokine production. In normal human skin, mTregs preferentially localized to hair follicles and were more abundant in skin with high hair density. Sequence comparison of TCRs from conventional memory T helper cells and mTregs isolated from skin revealed little homology between the two cell populations, suggesting that they recognize different antigens. Under steady-state conditions, mTregs were nonmigratory and relatively unresponsive; however, in inflamed skin from psoriasis patients, mTregs expanded, were highly proliferative, and produced low levels of IL-17. Taken together, these results identify a subset of Tregs that stably resides in human skin and suggest that these cells are qualitatively defective in inflammatory skin disease.

The Safety and Efficacy of Breast Implants for Augmentation Mammaplasty

This review of the efficacy and safety of breast implants was intended to focus on our current body of knowledge about these devices. There are informational gaps, but not all of these can be laid at the door of imperfect studies or failed scientific methods. Certain properties of the implants are still unmeasurable, immunologic investigation is still evolving, the cause of wound contraction is inexplicable here or in the burnscar contracture, and the indications for and results of this surgery necessarily are subjective. Still, there are a number of investigative avenues open to us, and our cumulative experience shows no reluctance on the part of plastic surgeons to initiate further studies.

Management of benign tumors of the adolescent breast.

Learning Objectives: After studying this article, the participant should be able to: 1. Describe the differential diagnosis of breast tumors in adolescent girls. 2. Compare and contrast surgical options for the management of adolescent breast tumors. 3. Recognize the utility of a reduction mammaplasty technique when resecting these larger tumors in adolescents. Summary: Although 99 percent of breast lesions in female adolescents are benign tumors, surgical intervention is commonly required. This article reviews the differential diagnosis, evaluation, and management of these benign tumors. A modified surgical technique for resection of large fibroadenomas and reconstruction of the remaining breast is described. The authors review the approach to five specific breast lesions: fibroadenomas, phyllodes tumors, juvenile hypertrophy, inflammatory processes, and premature breast development.

Psychological evaluation of patients undergoing breast reconstruction using two different methods: autologous tissues versus prostheses.

Breast reconstruction has become an available option for most patients undergoing mastectomy. In fact, many authors agree that breast reconstruction does not interfere with possible therapies and improves the womens quality of life. The aim of this study was to evaluate the psychological adjustment of patients who had immediate or delayed reconstruction using two different methods: implants and autologous tissues. Specifically, it was explored whether the different methods of breast reconstruction have caused significant changes in psychological functioning. The study population (102 patients) was derived from patients who underwent breast reconstruction in the period January 1988 to December 1991 at the Department of Plastic and Reconstructive Surgery of the National Institute for Cancer Research in Genoa, Italy. Fifty-two patients underwent breast reconstruction using implants and 50 using the transverse rectus abdominis myocutaneous (TRAM) flap. Demographic information was gathered from each patient. The psychological instruments consisted of three standardized self-administered questionnaires: Psychological Distress Inventory, State Trait Anxiety Inventory, Form Y, and the Eysenck Personality Inventory. To better assess the changes in body image after breast reconstruction, three more specific questions about sexual desire, physical image, and social relationships were added. The 102 patients assessed in this study indicated a low incidence of psychological distress. Impairment was reported regarding body image by patients who underwent delayed reconstruction; these patients also showed higher distress scores. The type of breast reconstruction also seems to influence body image, showing in the patients with TRAM flap reconstruction more relevant psychological discomfort.(ABSTRACT TRUNCATED AT 250 WORDS)

Antibiotic Prophylaxis for Preventing Surgical-Site Infection in Plastic Surgery: An Evidence-Based Consensus Conference Statement from the American Association of Plastic Surgeons

Background: There is a growing concern for microbial resistance as a result of overuse of antibiotics. Although guidelines have focused on the use of antibiotics for surgery in general, few have addressed plastic surgery specifically. The objective of this expert consensus conference was to evaluate the evidence for efficacy and safety of antibiotic prophylaxis in plastic surgical procedures. Methods: The authors searched for existing high-quality systematic reviews for antibiotic prophylaxis in the literature from the MEDLINE, Cochrane Library, and Embase databases. All synonyms for antibiotics were combined with terms for relevant plastic surgery procedures. The searches were not limited by language, and included all study designs. In addition, supplemental hand searches were performed of bibliographies of relevant articles, and extensive “related articles.” Meta-analyses were performed and reviewed by experts selected by the American Association of Plastic Surgeons to reach consensus recommendations. Results: Database searches identified 4300 articles, from which 2042 full-text articles were identified for eligibility. De novo meta-analyses were performed for each plastic surgical category. In total, 67 studies met the inclusion criteria, including nine for breast surgery, 17 for head and neck surgery, 10 for orthognathic surgery, seven for rhinoplasty/septoplasty, 19 for hand surgery, five for skin surgery, and two for abdominoplasty. Conclusions: Systemic antibiotic prophylaxis is recommended for clean breast surgery and for contaminated surgery of the hand or the head and neck. It is not recommended to reduce infection in clean surgical cases of the hand, skin, head and neck, or abdominoplasty.

Cavernous nerve repair with allogenic adipose matrix and autologous adipose-derived stem cells

OBJECTIVES To investigate whether adipose-derived matrix seeded with adipose-derived stem cells (ADSC) can facilitate the repair of injured cavernous nerves (CNs). METHODS Human and rat adipose tissues were decellularized and fabricated into various forms, including adipose tissue-derived acellular matrix thread (ADMT). ADMT seeded with ADSC were transplanted into subcutaneous space and examined for signs of inflammation. ADSC-seeded ADMTs were then used to repair CN injury in rats, followed by assessment of histology and erectile function. RESULTS Adipose tissue can be fabricated into acellular matrices of various shapes and sizes, including threads and sheets. Seeding of ADMT occurred rapidly: within 24 hours, 55% of the surface was covered with ADSC and within 1 week, 90% was covered. Transplantation of the seeded ADMT into the subcutaneous space of an allogenic host showed no signs of inflammatory reaction. At 3 months after grafting into CN injury rats, approximately twice as many cells were found on seeded ADMT as on unseeded ADMT. The seeded ADMT also had various degrees of S100 and neuronal nitric oxide synthase expression, suggesting CN axonal ingrowth. Rats grafted with seeded ADMT overall had the best erectile function recovery when compared with those grafted with unseeded ADMT and those ungrafted. However, as a result of large variations, the differences did not reach statistic significance (P = .07). CONCLUSIONS Grafting of ADSC-seeded matrix resulted in a substantial recovery of erectile function and improvement of histology. However, further refinement of the matrix architecture is needed to improve the success rate.

Plastic surgeons over 50: practice patterns, satisfaction, and retirement plans.

Background: Approximately 56 percent of all currently active plastic surgeons in the United States are older than 50 years and are likely to retire in the next 10 to 20 years. The 2006 Survey of Plastic Surgeons Over the Age of 50 was designed to provide insight regarding the practice patterns, retirement plans, and issues of importance to plastic surgeons older than 50 to provide an indicator of future workforce needs for the specialty. Methods: The survey was part of a larger study of physicians older than 50 across all specialties conducted by the Association of American Medical Colleges Center for Workforce Studies, in collaboration with the American Society of Plastic Surgeons, the American Medical Association, the Council of Medical Specialty Societies, and seven additional medical specialty associations. Surveys were mailed to 1434 active and retired plastic surgeons aged 50 to 79 years; the response rate was 59.1 percent. Results were compared with responses from physicians of all specialties. Results: Full-time reconstructive plastic surgeons older than 50 spend more hours per week practicing medicine (56.5 hours per week) than cosmetic plastic surgeons (49.7 hours per week) and all physicians (53.7 hours per week). Plastic surgeons retire slightly earlier than other physicians and cite rising malpractice costs, insufficient reimbursement, and increasing competition as important factors when considering retirement. Conclusions: There are significant differences in the practices, satisfaction, and factors influencing retirement plans for plastic surgeons that focus on cosmetic versus reconstructive surgery. Further study of these two components of plastic surgery may be warranted.

The effect of prostaglandin inhibitors on wound contraction and the myofibroblast.

The production and smooth muscle-like activity of the myofibroblast do not appear to be diminished in a granulating wound treated with prostaglandin inhibitors. Prostaglandins are mediators of inflammation and smooth-muscle stimulants, but inhibition of the prostaglandins and their precursors failed to alter the course of wound contraction and, by inference, the activity of the myofibroblast in this experimental model.

Malignant transformation in concurrent benign mixed tumors of the parotid and submaxillary glands.

This patient is the only reported case of concomitant mixed tumors of the parotid and contralateral submaxillary gland. Each lesion had histologic changes consistent with different stages in the transformation of a benign to a malignant mixed tumor. Identifying premalignant disease in the parotid tumor and early preinvasive carcinoma in the submaxillary tumor lends support to the concept of malignant progression in salivary gland mixed tumors.
