Hardware-Related Skin Erosion in Deep Brain Stimulation for Parkinson's Disease: How Far Can We Go? An Illustrative Case Report.

Skin erosion is a hardware-related complication commonly described after deep brain stimulation (DBS). Hardware exposure is often associated with the development of infection that can lead to implant removal. However, in selected cases, it is possible to manage skin erosion without having to remove the hardware. This article presents the case of a patient with recurrent skin erosions above the IPG, who underwent multiple surgeries. Given the failure of less invasive approaches, a more complex surgery with the employment of a pedunculated flap of pectoralis major in order to cover the IPG was attempted. Nevertheless, the IPG removal was finally unavoidable, resulting in a rapid decline in clinical performance. This illustrative case suggests how, in patients with sustained stimulation who benefit from a good degree of autonomy, it may be useful to use invasive surgical techniques to resolve skin erosions and save the DBS system. In spite of everything, sometimes complete or partial removal of the implant still becomes unavoidable, but this can lead to a severe worsening of PD symptoms. Definitive removal of the system should therefore be considered only in cases of frank infection or after failure of all other approaches.

Effectiveness of Blue light photobiomodulation therapy in the treatment of chronic wounds. Results of the Blue Light for Ulcer Reduction (B.L.U.R.) Study.

BACKGROUND: Lower limb ulcers not responding to standard treatments after 8 weeks are defined as chronic wounds, and they are a significant medical problem. Blue light (410-430 nm) proved to be effective in treating wounds, but there is a lack of data on chronic wounds in clinical practice. The aim of the study was to determine if blue light photobiomodulation with EmoLED (Emoled Srl, Sesto Fiorentino, Florence, Italy) medical device in addition to standard of care is more effective compared to standard of care alone in promoting re-epithelialization of chronic wounds of lower limbs in 10 weeks. METHODS: Ninety patients affected by multiple or large area ulcers were enrolled. To minimize all variabilities, each patient has been used as control of himself. Primary endpoint was the comparison of the re-epithelialization rate expressed as a percentage of the difference between the initial and final area. Secondary endpoints were: treatment safety, pain reduction, wound area reduction trend over time, healing rate. RESULTS: At week 10, the wounds treated with EmoLED in addition to standard care showed a smaller residual wound area compared to the wounds treated with standard of care alone: 42.1% vs. 63.4% (P=0.029). The difference is particularly evident in venous leg ulcers, 33.3% vs. 60.1% (P=0.007). 17 treated wounds and 12 controls showed complete healing at week 10. Patients showed a significant reduction in pain (P=2×10-7). CONCLUSIONS: Blue light treatment in addition to standard of care accelerates consistently the re-epithelialization rate of chronic wounds, especially venous leg ulcers and increases the chances of total wound healing in 10 weeks.

Experimental Study on Blue Light Interaction with Human Keloid-Derived Fibroblasts.

Keloids are an exuberant response to wound healing, characterized by an exaggerated synthesis of collagen, probably due to the increase of fibroblasts activity and to the reduction of their apoptosis rate: currently no standard treatments or pharmacological therapies are able to prevent keloid recurrence. To reach this goal, in recent years some physical treatments have been proposed, and among them the PhotoBioModulation therapy (PBM). This work analyses the effects of a blue LED light irradiation (410-430 nm, 0.69 W/cm2 power density) on human fibroblasts, isolated from both keloids and perilesional tissues. Different light doses (3.43-6.87-13.7-20.6-30.9 and 41.2 J/cm2) were tested. Biochemical assays and specific staining were used to assess cell metabolism, proliferation and viability. Micro-Raman spectroscopy was used to explore direct effects of the blue LED light on the Cytochrome C (Cyt C) oxidase. We also investigated the effects of the irradiation on ionic membrane currents by patch-clamp recordings. Our results showed that the blue LED light can modulate cell metabolism and proliferation, with a dose-dependent behavior and that these effects persist at least till 48 h after treatment. Furthermore, we demonstrated that the highest fluence value can reduce cell viability 24 h after irradiation in keloid-derived fibroblasts, while the same effect is observed 48 h after treatment in perilesional fibroblasts. Electrophysiological recordings showed that the medium dose (20.6 J/cm2) of blue LED light induces an enhancement of voltage-dependent outward currents elicited by a depolarizing ramp protocol. Overall, these data demonstrate the potentials that PBM shows as an innovative and minimally-invasive approach in the management of hypertrophic scars and keloids, in association with current treatments.

Integra in Scalp Reconstruction After Tumor Excision: Recommendations From a Multidisciplinary Advisory Board.

Integra is a dermal regeneration template used in the reconstruction of burns, traumatic injuries, or excision lesions in patients who present particular risk factors for traditional surgical procedures. A multidisciplinary advisory board of expert dermatologists and plastic surgeons have discussed the use of Integra in the reconstruction of scalp defects after tumor excision, focusing on the evidence derived from literature and on their experience in the treatment of approximately 400 patients. In this position paper, the authors summarize the main evidence discussed during the board, and the common practice guidelines proposed by the experts. The use of Integra is recommended in elderly patients with multiple comorbidities who have a higher risk for potential complications in traditional surgery; these patients may in fact benefit from a lower anesthetic risk, a less complicated postsurgical care and limited morbidity at the donor site obtained with the dermal template. Integra should also be used in the reconstruction of large and complex wounds and in case of bone exposure, as it helps to overcome the challenges related to wound healing in difficult areas. Notably, Integra has proven to be effective in patients who have undergone previous surgical procedures or adjuvant radiation therapy, in which previous incisions, scarring and radiation damages may hamper the effectiveness of traditional procedures. Finally, Integra is recommended in patients with recurrent and aggressive tumors who need closer tumor surveillance, as it gives easy access to the tumor site for oncologic follow-up examination.

Extracorporeal shock waves trigger tenogenic differentiation of human adipose-derived stem cells.

PURPOSES: Incomplete tendon healing impairs the outcome of tendon ruptures and tendinopathies. Human Adipose-derived Stem Cells (hASCs) are promising for tissue engineering applications. Extracorporeal Shock Waves (ESW) are a leading choice for the treatment of several tendinopathies. In this study, we investigated the effects of ESW treatment and tenogenic medium on the differentiation of hASCs into tenoblast-like cells. MATERIALS AND METHODS: hASCs were treated with ESW generated by a piezoelectric device and tenogenic medium. Quantitative real-time PCR was used to check the mRNA expression levels of tenogenic transcription factors, extracellular matrix proteins, and integrins. Western blot and immunofluorescence were used to detect collagen 1 and fibronectin. Collagen fibers were evaluated by Masson staining. Calcium deposition was assessed by Alizarin Red staining. RESULTS: The combined treatment improved the expression of the tendon transcription factors scleraxis and eyes absent 2, and of the extracellular matrix proteins fibronectin, collagen I, and tenomodulin. Cells acquired elongated and spindle shaped fibroblastic morphology; Masson staining revealed the appearance of collagen fibers. Finally, the combined treatment induced the expression of alpha 2, alpha 6, and beta 1 integrin subunits, suggesting a possible role in mediating ESW effects. CONCLUSIONS: ESW in combination with tenogenic medium improved the differentiation of hASCs toward tenoblast-like cells, providing the basis for ESW and hASCs to be used in tendon tissue engineering.

Quantum molecular resonance technology in hard-to-heal extremity wounds: histological and clinical results.

Chronic wounds are commonly associated with high morbidity rates due to the patient's need of frequent dressing changes and repeated visits to the outpatient wound clinic. Furthermore, chronic wounds are often characterised by severe pain, which can cause significant disability to the patient. New technologies aim to develop an optimal device to reduce discomfort of the patient and to heal wounds. The device Rexon-age® is introduced for the first time in wound healing, and preliminary data on clinical and histological results are shown. From April 2014 to April 2015, 11 patients - 7 females and 4 males - were enrolled in the present study. The study was conducted at the Plastic and Reconstructive Institute of the Università degli Studi di Torino, Città della Salute e della Scienza of Torino, Italy. For histological characterisation, pre- and post-treatment biopsies on the wound bed were performed. Data regarding age, gender, weight, height, comorbidity, drug therapy and topical pre-treatment and dressings of the wound were collected as well. Moreover, local factors regarding the wound data were as follows: aetiology, time of the wound formation until first Rexon-age treatment, wound dimensions, wound bed, moisture, margins and anatomical region of the wound. A visual analogue scale (VAS) was used to monitor the pain before and after each treatment. Rexon-age treatment resulted in improvement in granulation tissue and wound contraction. Moreover, a significant reduction of pain was observed with the reduction of painkillers drug usage. Among these Rexon-age-treated patients, three patients displayed 60-80% reduction in pain intensity, and two patients showed complete pain relief. In outpatient follow-up appointments, we registered long-term durability of pain relief. As assessed by histological analyses, post-treatment biopsies of all nine patients revealed a decreased amount of inflammatory cells and lower expression levels of metalloproteinases (e.g. MMP9). We observed increased capillary thrombosis as well as up-regulation of vascular endothelial growth factor (VEGF) expression. The current study presents the first evidence that Rexon-age-based therapy can significantly ameliorate and accelerate the healing process of chronic wounds. Although this study analysed only a small number of patients, we could consistently observe positive effects on both the clinical aspect of the lesions, which underwent size reduction and wound reactivation, and the quality of life of our patients due to long-term pain relief.

EWMA Document: Negative Pressure Wound Therapy.

1. Introduction Since its introduction in clinical practice in the early 1990's negative pressure wounds therapy (NPWT) has become widely used in the management of complex wounds in both inpatient and outpatient care.1 NPWT has been described as a effective treatment for wounds of many different aetiologies2,3 and suggested as a gold standard for treatment of wounds such as open abdominal wounds,4-6 dehisced sternal wounds following cardiac surgery7,8 and as a valuable agent in complex non-healing wounds.9,10 Increasingly, NPWT is being applied in the primary and home-care setting, where it is described as having the potential to improve the efficacy of wound management and help reduce the reliance on hospital-based care.11 While the potential of NPWT is promising and the clinical use of the treatment is widespread, highlevel evidence of its effectiveness and economic benefits remain sparse.12-14 The ongoing controversy regarding high-level evidence in wound care in general is well known. There is a consensus that clinical practice should be evidence-based, which can be difficult to achieve due to confusion about the value of the various approaches to wound management; however, we have to rely on the best available evidence. The need to review wound strategies and treatments in order to reduce the burden of care in an efficient way is urgent. If patients at risk of delayed wound healing are identified earlier and aggressive interventions are taken before the wound deteriorates and complications occur, both patient morbidity and health-care costs can be significantly reduced. There is further a fundamental confusion over the best way to evaluate the effectiveness of interventions in this complex patient population. This is illustrated by reviews of the value of various treatment strategies for non-healing wounds, which have highlighted methodological inconsistencies in primary research. This situation is confounded by differences in the advice given by regulatory and reimbursement bodies in various countries regarding both study design and the ways in which results are interpreted. In response to this confusion, the European Wound Management Association (EWMA) has been publishing a number of interdisciplinary documents15-19 with the intention of highlighting: The nature and extent of the problem for wound management: from the clinical perspective as well as that of care givers and the patients Evidence-based practice as an integration of clinical expertise with the best available clinical evidence from systematic research The nature and extent of the problem for wound management: from the policy maker and healthcare system perspectives The controversy regarding the value of various approaches to wound management and care is illustrated by the case of NPWT, synonymous with topical negative pressure or vacuum therapy and cited as branded VAC (vacuum-assisted closure) therapy. This is a mode of therapy used to encourage wound healing. It is used as a primary treatment of chronic wounds, in complex acute wounds and as an adjunct for temporary closure and wound bed preparation preceding surgical procedures such as skin grafts and flap surgery. Aim An increasing number of papers on the effect of NPWT are being published. However, due to the low evidence level the treatment remains controversial from the policy maker and health-care system's points of view-particularly with regard to evidence-based medicine. In response EWMA has established an interdisciplinary working group to describe the present knowledge with regard to NPWT and provide overview of its implications for organisation of care, documentation, communication, patient safety, and health economic aspects. These goals will be achieved by the following: Present the rational and scientific support for each delivered statement Uncover controversies and issues related to the use of NPWT in wound management Implications of implementing NPWT as a treatment strategy in the health-care system Provide information and offer perspectives of NPWT from the viewpoints of health-care staff, policy makers, politicians, industry, patients and hospital administrators who are indirectly or directly involved in wound management.

Extracorporeal shock waves modulate myofibroblast differentiation of adipose-derived stem cells.

Mesenchymal stem cells are precursors of myofibroblasts, cells deeply involved in promoting tissue repair and regeneration. However, since myofibroblast persistence is associated with the development of tissue fibrosis, the use of tools that can modulate stem cell differentiation toward myofibroblasts is central. Extracorporeal shock waves are transient short-term acoustic pulses first employed to treat urinary stones. They are a leading choice in the treatment of several orthopedic diseases and, notably, they have been reported as an effective treatment for patients with fibrotic sequels from burn scars. Based on these considerations, the aim of this study is to define the role of shock waves in modulating the differentiation of human adipose-derived stem cells toward myofibroblasts. Shock waves inhibit the development of a myofibroblast phenotype; they down-regulate the expression of the myofibroblast marker alpha smooth muscle actin and the extracellular matrix protein type I collagen. Functionally, stem cells acquire a more fibroblast-like profile characterized by a low contractility and a high migratory ability. Shock wave treatment reduces the expression of integrin alpha 11, a major collagen receptor in fibroblastic cells, involved in myofibroblast differentiation. Mechanistically, the resistance of integrin alpha 11-overexpressing cells to shock waves in terms of alpha smooth muscle actin expression and cell migration and contraction suggests also a role of this integrin in the translation of shock wave signal into stem cell responses. In conclusion, this in vitro study shows that stem cell differentiation toward myofibroblasts can be controlled by shock waves and, consequently, sustains their use as a therapeutic approach in reducing the risk of skin and tissue fibrosis.

Electrical stimulation for difficult wounds: only an alternative procedure?

In the wound healing research, the exact mechanism of action of different modalities of electrical stimulation (ES) remains controversial and unresolved. In this study we discuss a particular ES, with a different type of waveform, corresponding to the principle of stochastic resonance. Between July 2008 and May 2010, 32 patients were enrolled and ES was applied to wounds using the bioelectrical signal therapy (BST) device (LifeWave, Petach Tiqwa, Israel). The outcome evaluated in group 1 (n = 21) was wound healing, while group 2 (n = 11) was evaluated for wound-related pain [Visual Number Scale (VNS) pain scale] during treatment. In group 1, 87% of the wounds closed in an average time of 97 days (range 10-150 days); three patients were lost to follow-up. In group 2, 45% of the patients experienced a complete pain disappearance after 7 days of treatment; 36% reported a reduction in VNS from 9·3 to 3·2 in 7 days; 19% stopped morphine-like painkillers after 2 weeks. The clinical application of the stochastic resonance enables the usage of easy-to-use, non-invasive, painless and pain-relief treatment. Our experience with ES has demonstrated the BST device to be a very good alternative in cases of small size defects, compared with other therapies such as surgery, dressing and negative pressure devices.

Gauze-based negative pressure wound therapy: a valid method to manage pyoderma gangrenosum.

Pyoderma gangrenosum (PG) is an uncommon ulcerative, non-infective chronic inflammatory skin disorder of unknown aetiology. Systemic therapies are necessary to control the associated medical diseases, and, due to the inflammatory nature of PG, topical or systemic immunosuppressant agents are effective, but wound healing is usually slow. Negative wound pressure therapy (NPWT) has become an important tool for the management of complex skin ulcers, and usage in PG has been recently described in the literature: we present four cases of classic PG in which NPWT in association with systemic therapy achieved wound healing and a drastic pain reduction.

Preoperative color duplex echographical venous mapping before autologous fat graft for calf augmentation: a case report of superficial vein thrombosis and prevalence of intersaphenic anastomosis.

Autologous fat grafting for calf augmentation is considered an easy and safe technique. Only few cases of potential complications have been described in literature; among them, vein thrombosis was never reported. We report a case of superficial vein thrombosis of the intersaphenic anastomosis after fat graft for calf symmetrization in club-foot syndrome. A color duplex echographical study showed that such intersaphenic anastomoses are present in all patients, but they have an ectatic diameter in 70% of patients with great saphenous vein insufficiency and in 50% of patients without insufficiency. The plastic surgeon should be aware of the presence and topography of such anatomical variations before performing the procedure. Moreover, a preoperative color duplex echographical venous mapping may help the surgeon in avoiding the trauma on vein variants and subsequent complications.

Can single use negative pressure wound therapy be an alternative method to manage keloid scarring? A preliminary report of a clinical and ultrasound/colour-power-doppler study.

Keloid scarring represents a pathological healing where primary healing phenomenon is deviated from normal. Pico is a single use negative pressure wound therapy system originally introduced to manage open or just closed wounds. Pico dressing is made of silicone, and distributes an 80 mmHg negative pressure across wound bed. Combination of silicon layer and continuous compression could be a valid method to manage keloid scarring. Since November 2011, three patients were enrolled and evaluated before negative pressure treatment, at end of treatment (1 month) and 2 months later, through Vancouver Scar Scale (VSS), Visual Analog Scale (VAS) and a scoring system for itching. Ultrasound (US) and colour-power-doppler (CPD) examination was performed to evaluate thickness and vascularisation of the scar. One patient was discharged from study after 1 week. In last two patients, VSS, VAS and itching significantly improved after 1 month therapy and the results were stable after 2 months without any therapy. At end of therapy, the 'appearance of palisade vessels' disappeared in both cases at CPD exam; US showed a thickness reduction (average 43·8%). We propose a well-tolerated, non invasive treatment to manage keloid scarring. Prospective studies are necessary to investigate whether these preliminary observations are confirmed.

Treatment of chronic heel osteomyelitis in vasculopathic patients. Can the combined use of Integra® , skin graft and negative pressure wound therapy be considered a valid therapeutic approach after partial tangential calcanectomy?

Osteomyelitis of the calcaneus is a difficult problem to manage. Patients affected by osteomyelitis of the calcaneus often have a below-the-knee amputation because of their comorbidity. In this article, we present seven cases of heel ulcerations with chronic osteomyelitis treated with Integra(®) Dermal Regeneration Template, skin graft and negative pressure wound therapy after partial tangential calcanectomy, discussing the surgical and functional results. In this casuistic of patients, all wounds healed after skin grating of the neodermis generated by Integra(®), with no patient requiring a below-knee amputation.

Patient's pain feedback using negative pressure wound therapy with foam and gauze.

Wounds can be caused by different mechanisms and have a significant morbidity and mortality. Negative pressure wound therapy (NPWT) is one of the most successful treatment modalities for wound healing. We have been using both foam and gauze-based NPWT. During application of NPWT, we noticed that the patient's pain was of varying intensity depending on the filler used. The aim of our work was to compare the level of pain and feedback before, during the treatment and at the dressing change after treatment with NPWT with two different fillers. For this study, we compared a pool of 13 gauze-treated patients with a pool of 18 foam-treated patients regarding the level of pain and feedback before, during the treatment and at the dressing change after treatment with NPWT. They were all post-traumatic patients with loss of tissue up to the muscular band. The patients were asked to respond to a questionnaire interviewed by the same physician to assess the level of pain using VNS (verbal numerical scale). We observed similar difference of means before and during the treatment with NPWT with gauze and foam. Regarding the pain at the dressing change, the mean of the scores for the foam was 6·5 while for the gauze was 4·15. In this case, we noticed the most significant difference between means from the scores given: 2·35 which was a statistically significant difference between the two groups (P = 0·046). The finding of this study confirms less pain at the dressing change after treatment with gauze-based NPWT. In our opinion, this finding is related to the more adhesive property of the foam probably because of the ingrowth of the granulation tissue in the micropores present on the foam. Considering this statement, we recommend the foam for neuropathic and paraplegic patients and the gauze for patients with bone and tendon exposition wounds, patients that do not tolerate NPWT with foam and low compliant patient particularly paediatric and old-age patients. We remind that the performance of this study was not sponsored by any company.

Negative pressure wound therapy using gauze and foam: histological, immunohistochemical and ultrasonography morphological analysis of the granulation tissue and scar tissue. Preliminary report of a clinical study.

Negative pressure wound therapy (NPWT) is becoming routine for the preparation of wounds prior to grafting for wound closure. We have been using both foam- and gauze-based NPWT to prepare wounds for closure prior to skin grafting and have obtained similar proportions of closed wounds; 7/7 for wounds treated with gauze-based NPWT and 11/11 for wounds treated with foam-based NPWT. In our follow-up consultations we observed that skin grafts on the foam-treated patients were less pliable than those on the gauze-treated patients. To assess what the mechanism of this effect might be, we compared the specific details of the treatments of both 11 foam and 7 gauze patients, including depth, location, patients' age and co-morbidity; biopsies of granulation and scar tissue were taken and stained with haematoxylin-eosin and by Masson's trichrome staining and conducted ultrasound analysis of the closed wounds, to see if there were features which explained those effects. All foam patients were treated at -125 mm Hg for an average of 25·9 days before skin grafts were applied. All gauze patients were treated at -80 mm Hg for an average of 24·7 days before skin grafts were applied. Biopsies of granulation tissue prior to skin grafting from five foam and four gauze-based NPWT patients did not reveal any obvious histological differences between the treatments. Ultrasound analysis of the skin-grafted wounds showed an average depth of scar tissue of 18 mm in the wound beds of the foam-treated wounds and 7 mm in the gauze-treated ones. Biopsies taken on the scar tissue after treatment with the gauze showed a minor tissue thickness and disorganisation and less sclerotic components. The findings of this preliminary analysis suggest that foam-based NPWT may induce a thicker layer of scar tissue beneath skin grafts than gauze-based NPWT which might explain a reduced pliability of the reconstructed bed. At present it is unclear which mechanism might be responsible for the difference in pressure (-125 versus -80 mm Hg), either the length of the time taken to reconstruct the wound bed or the intrinsic nature of the foam or gauze on the tissue surface. Prospective studies are necessary to investigate whether these preliminary observations are confirmed and to investigate what the mechanism might be.

Surgical debridement with VERSAJET: an analysis of bacteria load of the wound bed pre- and post-treatment and skin graft taken. A preliminary pilot study.

Surgical debridement, which is used for the removal of necrotic tissue from a wound, is becoming more and more important in the treatment of skin injuries. VERSAJET (VERSAJET™, Versajet Hydrosurgery System, Smith and Nephew, Hull, UK) is one of the techniques used for wound debridement. Medical literature does not present either analytical or comparative data correlating the bacterial load with the VERSAJET treatment. For this reason, we have decided to carry out a study to evaluate the level of bacterial contamination before and after the surgical debridement treatment with VERSAJET and, in connection with this, the correlation between the bacterial load and the successful healing of the skin graft. We took a total of 100 bacteriological swabs, 50 before and 50 from 27 selected patients after the treatment with VERSAJET, with which the wound bed was prepared to receive the skin graft or Integra graft in order to acquire data about the level of bacterial contamination. After analysing all those data we can assume that reducing the bacterial load is not the only variable which the successful healing of the skin graft depends on. In conclusion, there is still many data to analyse and study in order to better understand the qualitative and quantitative presence of bacteria and the success of this future surgical procedure. We remind that the performance of this study was not sponsored by any company.

Leg perforators and leg length: an anatomic study focusing on topography and angiogenesis.

The highly variable anatomic distribution of lower leg perforators is explored, with a standardization based on leg length. The possibility of a correlation between leg length and number of perforators is investigated. Twenty-two lower limbs of cadavers were utilized for an anatomic study on the leg perforators branching from the three major vascular axes, anterior tibial, posterior tibial, and fibular. The parameters considered were the number of vascular pedicles per each major axis, the caliber, the distance of the fascial hole from the bony landmark (knee joint line), and the route of the vessels (muscular, septal). Arteries taken into account had a caliber of 0.5 mm or greater, with a maximum of 1.7 and a mean of 0.78. The perforators of the anterior tibial artery distribute along the entire length of the leg, but the peak of concentration is between second and third tenth and around the middle tenth. The fibular system provides perforators between the fourth and seventh tenth. The posterior tibial perforators concentrate to the middle third and to the supramalleolar region. A correlation exists between leg length and number of perforating vessels for the tibial vascular systems, possibly due to neoangiogenesis during growth, at the level of the metaphyseal plates. On the contrary no relationship was noticed for the fibular artery, whose perforators concentrate far from the growth cartilages. Some tenths where perforators concentrate are identifiable. Tibial systems have a perforator incidence depending on leg length, which, on the contrary, does not influence the number of fibular perforators.

Ramirez's abdominoplasty technique combined with intraperitoneal chemohyperthermia after surgical cytoreductive procedures for the treatment of advanced intraperitoneal cancer in patients with ventral hernia.

Patients affected by peritoneal carcinomatosis are frequently submitted to repeated laparotomies to reduce intra-abdominal bulky lesions and to enhance the systemic chemotherapeutic action. Aim of our study is to evaluate feasibility and results of cytoreductive surgery and intraperitoneal chemohypertermic (IPCH) perfusion combined with Ramirez's abdominoplastic technique in selected patients with voluminous ventral hernias.At the same time, we support the hypothesis that Ramirez' technique would allow a normal intra-abdominal pressure leading to an optimal capability of penetration of chemotherapeutic agents in IPCH.From January 1998 to December 2003, 30 patients were submitted to a surgical debulking and IPCH through a laparotomic approach involving a ventral hernia. After extensive cytoreductive surgery, we closed the large abdominal wall damage with Ramirez's abdominoplasty technique, followed by IPCH. The technique described by Ramirez uses bilateral muscle flap complexes transposed medially to reconstruct the central abdominal wall without using meshes to supply or reinforce the abdominal reconstruction.A total of 23 patients (76.7%) were completely cytoreducted and subjected to IPCH. Postoperative mortality was 1/30 (3.3%). Major morbidity was 5/30 (16.7%). After a mean follow-up of 3 years, no sign of recurrent ventral hernia was noted in the survivors.This study suggests that surgical debulking combined with IPCH is feasible in patients with a previously large abdominal wall defect using the functional Ramirez's abdominoplasty technique. The reconstructive technique allows a regular IPCH procedure without recurrence of the ventral hernia confirmed by clinical examination and abdominal computed tomography.

The Tripier reverse flap for reconstruction of the upper eyelid.

INTRODUCTION: The Tripier flap is a bipedicled bridge-shaped flap, originally designed on the upper eyelid. The classically described use was for reconstruction of split-thickness defects of the lower eyelid. In the literature no mention exists of bipedicled flaps from the lower eyelid for reconstructing the upper. CASE REPORT AND SURGICAL TECHNIQUE: Authors report a case of a partial thickness defect in the upper eyelid, reconstructed through a bipedicled bridge-shaped flap from the lower eyelid. The reconstructed lid healed uneventfully and 6 months' follow up is satisfactory with regard to reconstruction. CONCLUSION: The reverse Tripier flap is therefore a valid technique for the repair of the upper eyelid when other options are not feasible.
