Z Riedelová-Reicheltová, E Brynda, T Riedel
Fibrin is a versatile biopolymer that has been extensively used in tissue engineering. In this paper fibrin nanostructures prepared using a technique based on the catalytic effect of fibrin-bound thrombin are presented. This technique enables surface-attached thin fibrin networks to form with precisely regulated morphology without the development of fibrin gel in bulk solution. Moreover, the influence of changing the polymerization time, along with the antithrombin III and heparin concentrations on the morphology of fibrin nanostructures was explored...

We demonstrate that it is possible to use a nonabsorbable mesh for abdominal wall reconstruction after total wound rupture and successfully split-skin graft directly on the mesh. Sufficient granulation tissue formation prior to skin grafting was obtained with long-term use of negative pressure wound therapy (NPWT).

A 78-year-old man visited our hospital with a prolapsed hemorrhoid. He was referred to the dermatology unit due to the thickness and redness of the perianal skin. He was diagnosed as having extra mammary Paget's disease by skin biopsy. After a biopsy of the anal polyp was performed to investigate the primary site, he was diagnosed with early anal canal cancer with Pagetoid spread and underwent a radical operation. Abdominoperineal resection with skin(D2 prx D3 lymphadenectomy) was performed with perineal reconstruction using a gracilis muscle graft...

Invasive trophoblast from Day-34 horse conceptuses survives in extra-uterine sites in allogeneic recipients that are immunologically naïve to donor major histocompatibility complex class I antigens. The ectopic trophoblast retains its in utero characteristics, including similar lifespan, physiologic effect of its secreted product (equine chorionic gonadotrophin) upon the recipient's ovaries, and induction of host immune responses. Immunologic memory has not been considered previously in this experimental system...

BACKGROUND: Postburn axillary contractures are common and significantly impact quality of life. Simple release combined with split thickness skin grafting necessitates a donor site, requires immobilization, and may result in poor functional outcome. Common methods of adjacent tissue rearrangement are not well designed to treat broad linear contractures. Flaps from the back, flank, or arm can be used, but may come with significant donor site morbidity. We demonstrate the use of the STARplasty, a novel adjacent tissue rearrangement initially developed to treat neosyndactyly, as a useful reconstructive option for the release of Kurtzman type 1 posterior or anterior axillary contractures...

: The use of cultured epithelial autografts for the treatment of extensive burn wounds has become popular in recent years. We examined extensive burn wounds in 14 patients by using a combination of autograft and cultured epithelial autografts developed in Japan (JACE). METHODS: We undertook a skin biopsy at 2, 4, and 6 weeks after transplantation with JACE. By using electron microscopy we observed the engraftment process. RESULTS: In transmission electron microscope findings, we recognized the engraftment process of JACE...

Acquired scrotal giant muscular hamartoma is an uncommon benign lesion with fewer than 10 documented cases all over the world. It is characterized by a proliferation of dermal smooth muscle bundles of scrotum dartos fascia. The authors report a rare case of acquired scrotal giant muscular hamartoma, which occurred in a 70-year-old severely obese and diabetic man presenting with a progressive scrotal enlargement and swelling in the last year, causing marked reduction in quality of life and cosmetic problems...

BACKGROUND: After wide local excision of cutaneous melanoma, large defects not amenable to simple primary closure are often covered with skin grafts. We report our experience using the rhomboid and keystone flaps to immediately close large axial and extremity wounds after potentially curative surgery for non-head and neck melanomas. METHODS: Between January 2011 and September 2016, demographic, operative, pathologic, and outcome data were prospectively collected on 60 patients who underwent wide local excision of melanoma followed by immediate flap reconstruction...

Resurfacing large facial defect is a continuing challenge for plastic surgeons. Skin graft or free flap is hard to obtain satisfactory results or is beyond the skill of most surgeons. The authors performed 13 expended submental island flaps to resurface middle and lower facial defects and achieved satisfactory results. In the first stage operation, the authors implanted one soft tissue expander in the anterior neck region which was expanded over an average of 3 months. In the second stage operation, the authors elevated the expanded submental island flap to resurface facial defect...

BACKGROUND: Conventional reconstructive methods fail to achieve satisfactory results in total eyelid defect cases. Vascularized composite tissue allotransplantation might provide both good appearance and function for these patients. The structure of the eyelid is exceptional because it simultaneously consists of skin, connective tissue, the striated muscle, fiber structure, aponeuroses, and mucosa. Thus, before clinical application of eyelid allotransplantation, more experiments are needed to clarify the impact of ischemia, immunal suppressive agents, and deinnervation effects on these sophisticated structures...

The majority of surgical burn care involves the use of skin grafts. However, there are cases when flaps are required or provide superior outcomes both in the acute setting and for postburn reconstruction. Rarely discussed in the context of burn care, the perforator-based propeller flap is an important option to consider. We describe our experience with perforator-based propeller flaps in the acute and reconstructive phases of burn care. We reviewed demographics, indications, operative details, and outcomes for patients whose burn care included the use of a perforator-based propeller flap at our institution from May 2007 to April 2015...

Early tangential excision of the burn wound is essential for removal of necrotic tissue and promotion of burn wound healing process. However, the depth of the burn wound is not easily assessed during the tangential excision performed by hand-held dermatomes, and it may be possible to excise unburned vital dermis unnecessarily, which aids in primary epithelization of the burn wound by adnexal structures. We herein present early clinical results of steel wool-aided dermabrasion in patients with deep partial-thickness burns...

Immunosuppression in elderly recipients has been underappreciated in clinical trials. Here, we assessed age-specific effects of the calcineurin inhibitor Tacrolimus (TAC) in a murine transplant model and assessed its clinical relevance on human T-cells. Old recipient mice exhibited prolonged skin graft survival when compared to young animals following TAC administration. More importantly, half of the TAC dose was sufficient in old mice to achieve comparable systemic trough levels. TAC administration was able to reduce pro-inflammatory IFN-γ cytokine production and promote IL-10 production in old CD4(+) T-cells...

The "generalized severe" form of recessive dystrophic epidermolysis bullosa (RDEB-gen sev) is caused by bi-allelic null mutations in COL7A1, encoding type VII collagen. The absence of type VII collagen leads to blistering of the skin and mucous membranes upon the slightest trauma. Because most patients carry exonic point mutations or small insertions/deletions, most exons of COL7A1 are in-frame, and low levels of type VII collagen already drastically improve the disease phenotype, this gene seems a perfect candidate for antisense oligonucleotide (AON)-mediated exon skipping...

Dermatofibrosarcoma protuberans (DFSP) is a rare disease of dermal fibroblastic origin that accounts for less than 5% of all soft tissue sarcomas in adults. DFSP grows slowly and is an asymptomatic lesion at the initial diagnosis. Herein, we report a case of multiple pedunculated nodules as a variant of DFSP. A 47-year-old man presented with a 7-month history of multiple well-circumscribed, firm, pedunculated nodules on the inguinal area. Histopathologic examination results showed densely packed uniform spindle cells with a storiform and cartwheel pattern, and positivity for CD34...

BACKGROUND: The patient and observer scar assessment scale (POSAS) recently emerged as a promising method, reflecting both observer's and patient's opinions in evaluating scar. This tool was shown to be consistent and reliable in burn scar assessment, but it has not been tested in the setting of skin graft scar in skin cancer patients. OBJECTIVE: To evaluate facial skin graft scar applied to POSAS and to compare with objective scar assessment tools. METHODS: Twenty three patients, who diagnosed with facial cutaneous malignancy and transplanted skin after Mohs micrographic surgery, were recruited...

BACKGROUND: Penile cancer is a rare malignancy that is confined to the glans in up to four out of five cases. Although descriptions of glansectomy exist, there are no contemporary video explanations or large published single centre series. OBJECTIVE: To show the efficacy and safety of glansectomy and split-thickness skin graft (STSG) reconstruction. DESIGN, SETTING, AND PARTICIPANTS: Data were collected retrospectively for patients identified from surgical theatre diaries between February 2005 and January 2016...

BACKGROUND: A prominent role of hair follicle-derived cells in epidermal wound closure is now well established but clinical translation of basic research findings is scarce. Although skin punch grafts have been used as a therapeutic intervention to improve healing of chronic leg ulcers, they are normally harvested from nonhairy areas, thus not taking advantage of the reported role of the hair follicle as a wound-healing promoter. OBJECTIVE: We sought to substantiate the role of hair follicles in venous leg ulcer healing by transplanting hair follicle-containing versus nonhairy punch grafts...
