Skin grafts offer a dynamic repair option for nasal defects of appropriate size, depth, and location. Granulation and grafting can successfully be used as stand-alone reconstructive options or in conjunction with flap repair. This article reviews suitable indications for graft and granulation use in nasal repair to achieve optimum functional and esthetic outcomes.

BACKGROUND: Calcific uraemic arteriolopathy (calciphylaxis) is an unusual and potentially fatal condition characterised by small-vessel calcification and ischaemic skin necrosis. It mainly affects patients with end-stage renal disease (ESRD) on haemodialysis, but may rarely occur in the absence of ESRD in conditions such as primary hyperparathyroidism, malignancy, alcoholic liver disease and connective tissue disease. METHODS: We reviewed the records of all patients diagnosed with calciphylaxis while on renal replacement therapy at Tygerberg Hospital, Cape Town, South Africa, between 1990 and 2014, to describe its presentation, course and final outcome...

Nearly 80% of all burns include the hands of affected individuals. Skin grafting is the gold standard in burns treatment, but in the case of the burn wound bed, it may require the necessity of utilising skin substitutes to facilitate closure. The aim of this study is to assess the impact of a porcine-derived wound dressing (Oasis™) for application to hand burns compared to a synthetic dressing (Suprathel™). Comparative assessments were made, including the time to heal, quality of healing and pain intensity...

In this study, we analysed the effects of pure epidermal micrografts generated with an automated device in a standardised human wound model. Epidermal micrografts were harvested using an automated device. Micrografts were then transplanted onto split-skin donor sites. The target area was only partially covered with transplants to create an intra-individual control area. Wounds were evaluated by subjective assessment as well as measurements with combined laser and white light spectroscopy and cutometry. The epidermal graft sites remained completely stable, whereas control sites offered partially unstable and blistering areas...

BACKGROUND: Silicone oil injection can cause several complications including pain, cellulitis, abscesses, skin compromise, migration, embolism and multiorgan failure. Oil-infested tissue excision remains the solely treatment to prevent such complications. OBJECTIVES: The authors evaluate tumor-like excision of the oil-infested tissue as a treatment for patients experiencing silicone injections in the lower limbs, to both preserve aesthetic appearance and solve further risk of complication from silicone...

A major goal of testicular xenografting is to salvage germ cells from immature animals that cannot be used for reproduction and generate their offspring. In this study, we investigated whether porcine fetal testicular tissue would acquire the ability to produce sperm with full developmental competence after they had been cryopreserved and grafted into nude mice. Testicular fragments from fetuses at 35, 55 and 90 days postartificial insemination (dpi) were vitrified and stored in liquid nitrogen. Immediately after warming, testicular fragments at each fetal stage were transplanted under the back skin of castrated nude mice (Crlj:CD1-Foxn1(nu)) (35-, 55- and 90-dpi groups, respectively) (day 0 = grafting)...

Jean Kanitakis, Emmanuel Morelon
Vascularized composite tissue allografts include skin, which frequently undergoes, in the early post-graft period, acute rejections. The diagnosis of acute rejection may be difficult as it can be mimicked by several dermatoses. We present a bilateral hand allograft recipient who developed, 16.5 years post-graft, cutaneous lesions raising suspicion about rejection. Physical examination and skin biopsy were diagnostic of scabies. This ectoparasitosis should be added in the list of dermatoses that can mimic allograft rejection in vascular composite allografts...

OBJECTIVES: To investigate the disease-modifying effects of phosphodiesterase 4 (PDE4) inhibition in preclinical models of systemic sclerosis (SSc). METHODS: We studied the effects of PDE4 inhibition in a prevention and a treatment model of bleomycin-induced skin fibrosis, in the topoisomerase mouse model as well as in a model of sclerodermatous chronic graft-versus-host disease. To better understand the mode of action of PDE4 blockade in preclinical models of SSc, we investigated fibrosis-relevant mediators in fibroblasts and macrophages from healthy individuals and patients suffering from diffuse-cutaneous SSc on blockade of PDE4...

BACKGROUND: The liver as transplantation site for human pancreatic islets is a harsh microenvironment for islets and it lacks the ability to retrieve the graft. A retrievable, extrahepatic transplantation site that mimics the pancreatic environment is desired. Ideally this transplantation site should be located subdermal for easy surgical-access but this never resulted in normoglycemia. Here we describe the design and efficacy of a novel prevascularized, subcutaneously implanted, retrievable poly (D,L-lactide-co-ε-caprolactone) (PDLLCL) scaffold...

BACKGROUND: Kidney transplantation in recipients with a previous malignancy is often deferred 2-5 years after cancer treatment due to fear of cancer recurrence. In Norway, the required waiting period has been 1 year. METHODS: We compared patient and graft survival of recipients with pretransplant cancer to the outcomes of matched recipients without such cancer (comparators) using Cox regression. RESULTS: From 1963 to 2010, 377 of 5867 recipients (6...

Facial scaring is considered one of the most difficult cosmetic problems for any plastic surgeon to solve. The condition is more difficult if the direction of the scar is not parallel to relaxed skin tension lines. Attempts to manage this difficult situation included revisions using geometric designs, Z plasties or W plasties to camouflage the straight line visible scaring. The use of long-lasting resorbable sutures was tried too. Recently, the use of botulinum toxin during revision improved the results. Fractional CO2 lasers, microfat grafts, and platelet-rich plasma were added to the armamentarium...

For the treatment of skull defect compensation after neurosurgery, a customized artificial bone is often employed owing to its toughness and the relative ease of producing cosmetically good result. However, implants are vulnerable to infection and removal of implant is sometimes necessary. Several other treatment options such as autologous bone graft or free flap are likely to be considered for the secondary reconstruction to avoid reinfection; however, reimplantation of artificial bone is beneficial for the patients, being not concerned with donor site morbidity...

BACKGROUND: Reconstruction of large defects of the upper eyelid is challenging because of its complex anatomy and specialized function. The aim of this work is to develop a single-stage reconstruction procedure based on a new approach. The technique consists of the advancement of an orbicularis oculi myocutaneous flap designed within the blepharoplasty skin excision pattern. METHODS: After the tumor's excision is completed with clear margins, the borders of the flap are incised down to the submuscular plane inside the classical pattern of upper eyelid blepharoplasty...

Full-thickness wounds that have rendered patients candidates for amputation may require techniques that may include a combinatorial approach above traditional standard of care. The purpose of this retrospective study was to evaluate the effectiveness of an innovative approach whereby several therapies were combined to avoid amputation. Patients with full-thickness wounds who were previously recommended for amputation and were treated with the combinatorial approach of muscle flap reconstruction and concentrated bone marrow aspirate, platelet-rich plasma, INTEGRA Wound matrix, vacuum-assisted closure, and split-thickness skin grafts were assessed retrospectively...

Giant juvenile fibroadenomas are relatively rare, accounting for less than 1% fibroadenomas. Large breast tumors create significant asymmetry and provide unique reconstructive challenges after removal. In this case, we describe a 21-year-old female with delayed presentation of a giant fibroadenoma of the right breast. This represents an unusual presentation of benign breast disease requiring reduction of the skin envelope, extensive glandular resection, lower pole reconstruction, and free nipple grafting to achieve symmetry with the opposite breast...
