The Safe Practice of Female Genital Plastic Surgery.

The purpose of this article is to guide surgeons in the safe practice of female genital plastic surgery when the number of such cases is steadily increasing. A careful review of salient things to look for in the patient's motivation, medical history, and physical examination can help the surgeon wisely choose best candidates. The anatomy is described, with particular attention given to the variations not generally described in textbooks or articles. Descriptions are included for labiaplasty, including clitoral hood reduction, majoraplasty, monsplasty, and perineoplasty with vaginoplasty. Reduction of anesthetic risks, deep venous thromboses, and pulmonary emboli are discussed, with special consideration for avoidance of nerve injury and compartment syndrome. Postoperative care of a variety of vulvovaginal procedures is discussed. Videos showing anatomic variations and surgical techniques of common female genital procedures with recommendations to reduce the complication rate are included in the article.

Re-excision of incompletely excised cutaneous squamous cell carcinoma: histological findings influence prognosis.

INTRODUCTION: We have previously shown 28.6% of re-excisions for margin-positive cutaneous SCC to yield residual tumour (positive re-excision). Original tumour diameter and thickness conferred significant risks for positive re-excision. We now report a 5-year prospective follow-up of our re-excision cohort. RESULTS: Of 676 consecutive SCC patients, 84 underwent wider-excision for positive margins. 79 of these patients completed a mean of 28 months follow-up. Overall, 9/79 (11%) of this re-excision cohort experienced locoregional recurrence, all within 2 years of primary resection. Of the positive re-excisions, 29% experienced recurrence, vs 5% in those with negative re-excisions. Logistic-regression analysis revealed positive re-excision to predict recurrence (P<0.05, RR 10.1), independent from tumour-grade, anatomical site, size, and delay to re-excision. CONCLUSION: Factors associated with residual tumour on re-excision are similar to characteristics of high-risk SCCs; larger tumours in particular are more likely to persist and may benefit from wider excision-margins at original resection. Positive re-excision is newly identified as a significant risk for locoregional recurrence, whilst negative re-excision is associated with a return to a low-risk prognosis, for all tumours. Our findings thus support the treatment of cutaneous SCC through to completion. We also recommend re-excision where narrow or close margins are reported. Patients with a positive re-excision should be considered at high risk for recurrence, requiring extended follow-up.

Metachronous melanoma in breast reconstruction patients.

The incidence and mortality due to malignant melanoma has increased three- to four-fold across males and females in England and Wales over the past thirty years. Ninety percent of patients with primary melanoma have no clinical evidence of lymphadenopathy at presentation. In this paper we describe our management of impalpable axillary melanoma deposits in a patient with a pedicled latissimus dorsi (LD) flap reconstruction to the ipsilateral breast. No such case has been previously described in the literature.

Topical negative pressure wound therapy: a review of its role and guidelines for its use in the management of acute wounds.

Over the past two decades, topical negative pressure (TNP) wound therapy has gained wide acceptance as a genuine strategy in the treatment algorithm for a wide variety of acute and chronic wounds. Although extensive experimental and clinical evidence exists to support its use and despite the recent emergence of randomised control trials, its role and indications have yet to be fully determined. This article provides a qualitative overview of the published literature appertaining to the use of TNP therapy in the management of acute wounds by an international panel of experts using standard methods of appraisal. Particular focus is applied to the use of TNP for the open abdomen, sternal wounds, lower limb trauma, burns and tissue coverage with grafts and dermal substitutes. We provide evidence-based recommendations for indications and techniques in TNP wound therapy and, where studies are insufficient, consensus on best practice.

Evidence-based medicine: vacuum-assisted closure in wound care management.

A review of the evidence base for the use of vacuum-assisted closure (VAC) therapy is presented, analysing both experimental and clinical data.

Interface dressings influence the delivery of topical negative-pressure therapy.

BACKGROUND: Topical negative-pressure therapy is a widely used wound management system that generates a negative pressure at the wound surface through a foam pad, which aids in wound stimulation through mechanical forces on the wound bed. System guidelines state that the foam dressing should be placed in direct apposition with the wound surface; however, an interface dressing is often inserted at this point to promote comfort at dressing changes. METHODS: Topical negative-pressure dressings were applied to 40 healthy volunteers. Pressures at the skin surface under the dressing were recorded and compared with those measured by a topical negative-pressure machine using the Therapeutic Regulated Accurate Care pad system. These were repeated, inserting different types of interface dressings: petroleum jelly (Vaseline)-impregnated gauze, nonadherent silicone dressing, and mylar polyester film dressing. RESULTS: Pressures recorded at the skin interface with no interface dressing were close to those set on the topical negative-pressure machine (mean pressure change, -5.11 +/- 0.55 mmHg). Interposition of dressings at the skin/foam interface affected pressure transmission through the foam, and some caused significant decreases in pressures recorded at the skin surface (e.g., Vaseline-impregnated gauze: mean pressure change, -11.76 mmHg; maximum pressure change, -41 mmHg). CONCLUSION: The loss in negative pressure means that pressures designated by the machine cannot be relied on as a measure of wound pressure when certain dressings are used at the interface. This could be important in determining the outcome of some wounds under topical negative-pressure therapy treatment.

Radiotherapy and wound healing.

Radiotherapy is an invaluable weapon when treating cancer. However, the deleterious effects of radiation, both immediate and long-term, may have a significant effect on local tissues. Problematic wound healing in radiation-damaged tissue constitutes a major problem that is frequently overlooked during the management of patients who require radiotherapy, or have had radiotherapy in the past. Poor wound healing may lead to chronic ulceration, pain, secondary infection and psychological distress and compromise the outcome of general or reconstructive surgery. We discuss the pathophysiology of poor wound healing following radiotherapy, specific problems for radiation-damaged tissue and potential treatments to improve wound healing of irradiated tissues.

Topical radiant heating in wound healing: an experimental study in a donor site wound model*.

The importance of temperature in the wound-healing process is rapidly being recognised as a novel way in which to manipulate the wound-healing environment. In this study, we aimed to investigate the direct effect of topical radiant heating (TRH), using a novel bandaging system (Warm-Up, Arizant Health care Inc., Eden Prairie MN, USA; Augustine Medical, USA), on wound healing at a physiological and cellular level. Experimental bandages were positioned over split-thickness skin graft donor site wounds of 12 patients undergoing graft harvesting from the anterior thigh. The experimental group (n=6) underwent intermittent heating for 5 hours (three 1-hour heating cycles at 38 degrees C, separated by two 1-hour rest periods), whilst the control group (n=6) received no radiant heating. Physiological blood-flow recordings both in the control group and the topical radiant heat cohort were undertaken using Laser Doppler Imaging (LDI). Skin biopsies were obtained at identical time points, and immunohistochemical analysis was undertaken using antibodies against neutrophils (NP57), lymphocytes (CD3) and macrophages (CD68). We found that TRH significantly increased local dermal blood flow (P<0.001) by up to 100% in both injured and intact skin. Furthermore, this increase in flow was associated with a significant (P<0.05) increase in CD3 immunoreactivity on day 1 postoperatively. This study demonstrates that TRH increases local blood flow and lymphocyte (CD3) extravasation, and we postulate that these changes may enhance local innate immunity within the healing wound environment.

Telemedicine in wound healing.

Better care for patients and improved health care depends on the availability of good information which is accessible when and where it is needed. The development of technology, more specifically the Internet, has expanded the means whereby information can be acquired and transmitted over large distances enabling the concept of telemedicine to become a reality. Telemedicine, defined as the practise of medicine at a distance, encompasses diagnosis, education and treatment. It is a technology that many thought would expand rapidly and change the face of medicine. However, this has not happened and during the last decade although certain telemedicine applications, such as video-consulting and teleradiology, have matured to become essential health care services in some countries, others, such as telepathology, remain the subject of intensive research effort. Telemedicine can be used in almost any medical specialty although the specialties best suited are those with a high visual component. Wound healing and wound management is thus a prime candidate for telemedicine. Development of a suitable telemedical system in this field could have a significant effect on wound care in the community, tertiary referral patterns and hospital admission rates.

Necrotising fasciitis: a new management algorithm based on clinical classification.

Necrotising fasciitis is a rare infection of the subcutaneous tissues. If untreated, it is invariably fatal, and thus a high index of suspicion for the diagnosis is required. The disease's manifestation can range from a fulminant presentation to a subtle and insidious development. The priority in every case is to proceed to radical surgical debridement. On review of the literature and based on our clinical experience, we propose a new classification based on clinical presentation and suggest an algorithm to facilitate the management of this devastating condition. Increasing awareness should be given to the management of the large wounds resulting from the surgical debridement of necrotising fasciitis.

Topical negative pressure therapy: mechanisms and indications.

Topical negative pressure (TNP) therapy has emerged as a high-technology, microprocessor-controlled physical wound-healing modality. Complex effects at the wound-dressing interface following application of a controlled vacuum force have been documented. These include changes on a microscopic, molecular level and on a macroscopic, tissue level: interstitial fluid flow and exudate management, oedema reduction, effects on wound perfusion, protease profiles, growth factor and cytokine expression and cellular activity, all leading to enhanced granulation tissue formation and improved wound-healing parameters. Primary indications for clinical use have been documented and include traumatic wounds, open abdominal wounds, infected sternotomy wounds, wound bed preparation, complex diabetic wounds and skin-graft fixation. Whilst this therapy now forms an essential part of the wound healing armamentarium, extensive clinical trials are recommended to confirm efficacy and delineate its optimum use.
