The evolution of perforator flap breast reconstruction: twenty years after the first DIEP flap.

It is over 20 years since the inaugural deep inferior epigastric perforator (DIEP) flap breast reconstruction. We review the type of flap utilized and indications in 2,850 microvascular breast reconstruction over the subsequent 20 years in the senior author's practice (Robert J. Allen). Data were extracted from a personal logbook of all microsurgical free flap breast reconstructions performed between August 1992 and August 2012. Indication for surgery; mastectomy pattern in primary reconstruction; flap type, whether unilateral or bilateral; recipient vessels; and adjunctive procedures were recorded. The DIEP was the most commonly performed flap (66%), followed by the superior gluteal artery perforator flap (12%), superficial inferior epigastric artery perforator flap (9%), inferior gluteal artery perforator flap (6%), profunda artery perforator flap (3%), and transverse upper gracilis flap (3%). Primary reconstruction accounted for 1,430 flaps (50%), secondary 992 (35%), and tertiary 425 (15%). As simultaneous bilateral reconstructions, 59% flaps were performed. With each flap, there typically ensues a period of enthusiasm which translated into surge in flap numbers. However, each flap has its own nuances and characteristics that influence patient and physician choice. Of note, each newly introduced flap, either buttock or thigh, results in a sharp decline in its predecessor. In this practice, the DIEP flap has remained the first choice in autologous breast reconstruction.

Dedicated general practitioner education sessions can improve diagnostic capabilities and may have a positive effect on referral patterns for common skin lesions.

INTRODUCTION: General practitioners (GPs) require the necessary skills to identify potentially malignant skin lesions and refer patients in an appropriate and timely manner. We examined the impact of a single consultant delivered education session to GP trainees on their diagnosis of common skin lesions. METHODS: A prospective analysis of baseline knowledge was assessed using a photographic questionnaire. A dedicated education session was delivered by a consultant plastic surgeon. Their knowledge was re-assessed after 3 months. RESULTS: There were 23 participants. Baseline ability to correctly diagnose skin lesions improved significantly at 3 months following dedicated teaching (baseline mean 30.2%, 3-month mean 65.9%, p = 0.001). All trainees recommended that dedicated skin education should be incorporated into GP training curricula. CONCLUSION: Dedicated education sessions on skin lesions can improve the diagnostic accuracy of GP trainees, and we suggest that they are incorporated into the GP training curriculum.

Is satisfaction with surgeon a determining factor in patient reported outcomes in breast reconstruction?

BACKGROUND: Patient reported outcomes are increasingly being taken into account in planning health service provision. Few studies have examined how the process of care influences patients' perception of outcome. The aim of the current study was to quantify patient satisfaction with breast reconstruction and to examine the demographic, disease and process-of-care variables that contributed to satisfaction with breasts and overall outcome. METHODS: A cross-sectional study was designed and the BREAST-Q outcomes assessment instrument was used to evaluate patient-reported psychosocial, physical and sexual well-being, as well as satisfaction with breasts, overall outcome and process of care. To identify factors predictive of satisfaction with breasts and overall outcome, the relation between covariates and each of these scales was assessed using linear regression models. RESULTS: Sixty one patients, with a mean age of 50 years, completed the survey. Mean satisfaction with breasts was 59.6% and satisfaction with overall outcome was 73.2%. Satisfaction across health-related quality of life scales ranged from 44.6% for sexual well-being to 74.6% for physical well-being. The mean rating for psychosocial well-being was 67.9%. Satisfaction ratings for surgeon, medical staff and office staff were all over 90%. Satisfaction with plastic surgeon was predictive of satisfaction with outcome and satisfaction with breasts (P = 0.001 and 0.021 respectively). DISCUSSION: The surgeon-patient relationship significantly influences patient reported outcomes in breast reconstruction. Further service development must recognize the need for additional time and personnel to deliver high standard, patient-centered care.

21 year follow up of a DIEP (deep inferior epigastric perforator) flap: a tale of a "nulltiple".

Since the first description of "The free abdominoplasty flap for breast reconstruction" by Hans Holmstrom in 1979, [see Ref. 1] the use of lower abdominal tissue has revolutionised reconstruction of the breast. DIEP (deep inferior epigastric perforator) free flap offers an abundance of reconstructive material, aesthetically-pleasing results and limited donor site morbidity. We report our first case of breast reconstruction with what presently is known as DIEP flap, performed in 1991 at St. Andrew's Centre for Plastic Surgery and Burns in Essex, The United Kingdom and the recent follow up results. We also discuss the historical events surrounding the evolution of this unpublished case and other documented cases.

Autologous microvascular breast reconstruction.

Autologous microvascular breast reconstruction is widely accepted as a key component of breast cancer treatment. There are two basic donor sites; the anterior abdominal wall and the thigh/buttock region. Each of these regions provides for a number of flaps that are successfully utilised in breast reconstruction. Refinement of surgical technique and the drive towards minimising donor site morbidity whilst maximising flap vascularity in breast reconstruction has seen an evolution towards perforator based flap reconstructions, however myocutaneous flaps are still commonly practiced. We review herein the current methods of autologous microvascular breast reconstruction.

Raman spectroscopic analysis of human skin tissue sections ex-vivo: evaluation of the effects of tissue processing and dewaxing.

Raman spectroscopy coupled with K-means clustering analysis (KMCA) is employed to elucidate the biochemical structure of human skin tissue sections and the effects of tissue processing. Both hand and thigh sections of human cadavers were analyzed in their unprocessed and formalin-fixed, paraffin-processed (FFPP), and subsequently dewaxed forms. In unprocessed sections, KMCA reveals clear differentiation of the stratum corneum (SC), intermediate underlying epithelium, and dermal layers for sections from both anatomical sites. The SC is seen to be relatively rich in lipidic content; the spectrum of the subjacent layers is strongly influenced by the presence of melanin, while that of the dermis is dominated by the characteristics of collagen. For a given anatomical site, little difference in layer structure and biochemistry is observed between samples from different cadavers. However, the hand and thigh sections are consistently differentiated for all cadavers, largely based on lipidic profiles. In dewaxed FFPP samples, while the SC, intermediate, and dermal layers are clearly differentiated by KMCA of Raman maps of tissue sections, the lipidic contributions to the spectra are significantly reduced, with the result that respective skin layers from different anatomical sites become indistinguishable. While efficient at removing the fixing wax, the tissue processing also efficiently removes the structurally similar lipidic components of the skin layers. In studies of dermatological processes in which lipids play an important role, such as wound healing, dewaxed samples are therefore not appropriate. Removal of the lipids does however accentuate the spectral features of the cellular and protein components, which may be more appropriate for retrospective analysis of disease progression and biochemical analysis using tissue banks.

Epidermoid cyst post dermofasciectomy.

We report the finding of an unusual presentation of an epidermoid cyst 3 years following dermofasciectomy for Dupuytren's disease. Epidermoid cysts remain a rare entity in the palmoplanter distribution but also a very unusual finding within the confines of a full thickness skin graft.

Structural adaptation and intracortical bone turnover in an ovine model of osteoporosis.

Compact bone makes up approximately 80% of the human skeletal mass. This study examines the effect of estrogen deficiency on compact bone turnover and associated geometrical structural adaptation over a 31-month period in a large animal model. Twenty-seven skeletally mature sheep were divided into control (n = 16) and ovariectomy group (OVX, n = 11). Animals were administered five different fluorochrome dyes to label intracortical bone turnover, and sacrificed at 31 months. Compact bone samples were analyzed for cortical geometry, intracortical turnover at five time points, resorption cavities, porosity, and compressive strength. Intracortical bone turnover was significantly increased in OVX, which demonstrated seasonal variation. Cross-sectional area in OVX was significantly greater than control and was associated with an increased section modulus. Intracortical porosity was significantly increased in OVX, however, there was no significant difference in ultimate compressive strength between the groups. Our results demonstrate increased intracortical bone turnover, resportion spaces, and porosity in OVX, without adversely affecting compressive strength. Our results also support the hypothesis of geometrical adaptation of compact bone in response to estrogen deficiency. These results suggest an early structural compensatory response in compact bone, despite increased intracortical turnover.

Silver nitrate masquerading as a radiopaque foreign body.

Silver nitrate is commonly used as a method of chemical cauterization to areas of hypergranulation. We report two cases wherein silver nitrate in the hand was misinterpreted radiologically as foreign bodies.

Postoperative stiffness and adhesion formation around repaired and immobilized Achilles tenotomies are prevented using a model of heat shock protein induction.

BACKGROUND: Tendon repair and subsequent immobilization is frequently complicated by postoperative stiffness secondary to inflammation and peritendinous adhesions. Thermal preconditioning is known to reduce inflammation by inducing formation of cytoprotective heat shock proteins. This study evaluates the role of thermal preconditioning following complete division and repair of the Achilles tendon, with subsequent immobilization, mimicking the typical clinical scenario. MATERIALS AND METHODS: Twenty-four New Zealand White rabbits were used in the study. The treatment group underwent thermal preconditioning, by elevating their core temperature to 41.5 degrees C for 20 minutes. The Achilles tendon of the hindlimb was divided and repaired 18 hours following thermal preconditioning. The animals were sacrificed following 3 weeks of immobilization. Range of movement of the ankle, tendon gliding, quantity of adhesions, and weight of repaired tendons were assessed. RESULTS: Loss of range of movement at the ankle was significantly less in the treatment group versus controls (P = 0.02). The quantity of adhesions and weight of the repaired tendons were significantly reduced in the treatment group (P = <0.001 and P = 0.005, respectively). Tendon gliding relative to the surrounding soft tissue was also significantly improved in the treatment group (P = 0.002). CONCLUSION: Preconditioned animals demonstrated a significantly better range of ankle movement, decreases in adhesion formation and in the gliding, and dimensions of tendons. Thermal preconditioning therefore has the potential to improve clinical results in tendon surgery following repair and immobilization.
