Peggy Chen, Harvey Smith, Carl Vinciullo
BACKGROUND: In Mohs micrographic surgery (MMS), the standard local anesthetic agent used is lignocaine with adrenaline. However, MMS can be prolonged; thus reinjections of local anesthetics are often required. OBJECTIVE: Is 0.5% bupivacaine with 1:200,000 epinephrine a useful adjunctive treatment when compared with the use of 1% lidocaine with 1:100,000 epinephrine in MMS for the nose? METHODS: Participants undergoing MMS received 2.5 mL of 1% lidocaine with 1:100,000 epinephrine before commencement of Stage 1...

Leukocyte adhesion defect I is a rare disorder (1:1,000,000) caused by diminished expression of CD-18 β2 integrins on leukocytes leading to abnormal adhesion, migration, and chemotaxis. Clinical manifestations include delayed separation of umbilical cord, omphalitis, recurrent severe infections, impaired wound healing, persistent oral ulcers, and severe periodontitis in primary and permanent dentition. A 5-year-old girl, second-born child to parents with consanguinity, presented with pain and mobility of lower teeth...

#3
Roongsak Limthongthang, Perajit Eamsobhana
BACKGROUND: There were very few options available for distal foot and toe defects that required a vascularized flap for coverage. As such, the use of a free flap was often justified in this region of the foot. The use of perforator flaps has created a new subset of local tissue transfer alternatives that increases the potential that the difficulties associated with microvascular tissue transfers could be avoided. The first dorsal metatarsal artery (FDMA) perforator flap was one variant of this new type of tissue transfer...

Current literature on risk factors for surgical site infection (SSI) in dermatological surgery in the absence of antibiotic prophylaxis is limited. The aim of this study was to retrospectively evaluate patients presenting for dermatological surgery. A total of 1,977 procedures were reviewed. SSI was clinically suspected in 79 (4.0%) patients and confirmed by culture in 38 (1.9%). Using the strictest definition of SSI (clinical symptoms with positive culture) significantly higher risk of SSI was found for location on the ear (odds ratio (OR) 6...

REVIEW
Dimitra Kiritsi, Alexander Nyström
Wound healing is one of the most complex processes in multicellular organisms, involving numerous intra- and intercellular signalling pathways in various cell types. It involves extensive communication between the cellular constituents of diverse skin compartments and its extracellular matrix. Miscommunication during healing may have two distinct damaging consequences: the development of a chronic wound or the formation of a hypertrophic scar/keloid. Chronic wounds are defined as barrier defects that have not proceeded through orderly and timely reparation to regain structural and functional integrity...

BACKGROUND: Acne vulgaris is a common skin defect, usually occurring during adolescence, but often it can persist in adults leaving permanent face scarring. Acne is usually treated with topical drugs, oral antibiotics, retinoids, and hormonal therapies, but medicinal plants are increasingly employed. OBJECTIVE: To investigate the protective role of white willow bark (WWB) and 1,2-decanediol (DD) on the damage caused by lipopolysaccharides (LPS) on human adult keratinocytes (HaCaT)...

Epithelial cells are responsible for tissue homeostasis and form a barrier to maintain chemical gradients and mechanical integrity. Therefore, rapid wound closure is crucial for proper tissue function and restoring homeostasis. In this study, the mechanical properties of cells surrounding a single-cell wound are investigated during closure of the defect. The single-cell wound is induced in an intact layer using micropipette action and responses in neighboring cells are monitored with atomic force microscopy...

Intestinal epithelial cells form a barrier that is critical in protecting the host from the hostile luminal environment. Previously, we showed that lysophosphatidic acid receptor 1 (LPAR1) regulates proliferation of intestinal epithelial cells such that the absence of LPA1 mitigates epithelial wound healing process. This study provides evidence that LPA1 is important for the maintenance of epithelial barrier integrity. The epithelial permeability, determined by fluorescently labeled dextran flux and transepithelial resistance, is increased in Lpar1(-/-) (Lpa1(-/-)) mouse intestine...

BACKGROUND: Reconstruction of chronic lower extremity wounds remains challenging. These wounds are mainly associated with diabetes mellitus, infections, and osteomyelitis. Although several reconstructive techniques are available, the peroneal artery perforator flap has unique advantages. METHODS: In this study, we discuss our experiences with peroneal artery perforator flaps in 55 patients who had suffered from chronic lower limb wounds. The size of the defect, comorbidities, etiology, flap size, and complications were recorded and analyzed based on a retrospective chart review...

BACKGROUND: Reconstruction of posterior thoracic and trunk defects can prove challenging even to the most seasoned surgeons. Many commonly used techniques for closing back defects include primary closure and split skin grafts. Often times, however, other techniques are needed in order to give the patient the best aesthetic and functional outcome. In this study, we focus on and evaluate donor site closure techniques for defects in the back created by harvesting scapular and parascapular flaps...

We examined the effectiveness of localized administration of fibroblast growth factor-2 containing low-molecular-weight heparin/protamine nanoparticles (FGF-2&LMWH/P NPs) on apoptosis in vivo and on healing of radiation-induced skin injury in a rat model. FGF-2 binds onto LMWH/P NPs, which can significantly enhance and stabilize FGF-2 as a local carrier. X-irradiation at a dose of 25 Gy was administered to the lower part of the back (using a lead sheet with two holes) 1 h before the administration of FGF-2&LMWH/P NPs...

Insulin signaling defects could lead to insulin resistance in insulin target organs: typically, in the muscler, liver, and adipose tissue. We have observed that insulin accelerated diabetic wound healing in our previous works; to further elucidate the mechanism, we investigated the expression and activation of insulin and insulin-like growth factor (IGF)-1 signaling, compared insulin sensitivity in skin tissue with that in liver tissue, and also observed the regulation of insulin on inflammatory response of wounds during the healing process...

Background: The aim of our study was to test the long-term efficacy of Endo-SPONGE(®) therapy in a group of patients treated in our center with vacuum-assisted therapy because of anastomotic leakages after colorectal surgery. Methods: Eleven patients [male: 6; mean age: 71 (range: 44-82) years] who had anastomotic leakage treated with Endo-SPONGE(®) placement were included in the study. Patient records were examined retrospectively. All patients with documented anastomotic leakage on abdominal computed tomography following an anterior resection of the rectum for rectal cancer underwent sigmoidoscopy to determine the extent of the anastomotic defect and the size of the presacral abscess...

BACKGROUND: Full thickness skin graft (FTSG) gives better outcomes than split thickness skin graft (STSG), but it has the drawback of limited donor sites. Anterolateral thigh (ALT), a popular donor site of STSG, is also a popular donor site of perforator flaps. This area has the advantage of large flap size available with primary closure. Based on this we harvested FTSG instead of STSG from the ALT. METHODS: We retrospectively reviewed 10 cases of FTSG from the ALT, with the recipient site of foot in 3, ankle in 2, lower leg in 2, forearm in 2, and wrist in 1 patient...

Aim Coverage of a deep sternal wound infection with a greater omentum flap. Due to a persistent infection caused by an infected aortic prosthesis, the primarily performed reconstruction with a latissimus dorsi flap had to be revised, and an alternative solution had to be found. Indication A deep sternal wound infection is a rare but devastating complication following median sternotomy. If the commonly used muscle flap is not sufficient and artificial material is still present in the wound, for instant drivelines or a vascular prosthesis, the greater omentum flap is a useful option due to its immunologic capacity...

Background and purpose - The number of revision total knee arthroplasties (TKA) is continuously increasing, leading to a growing need for reliable management of metaphyseal bone loss. We evaluated patients operated with a TKA using metal metaphyseal sleeves for bone defects with a minimum 5-year follow-up. Patients and methods - 37 patients had been operated on. 3 patients died and 3 patients were lost during follow-up. Of the 31 remainders (20 women), 9 had been operated on with a primary TKA and 22 with a revision TKA at the index surgery...

BACKGROUND: management of encephaloceles is challenging when massive brain herniation is present. In such instances, an expansile cranioplasty may be attempted so as to preserve some herniated brain tissue. Complications such as wound dehiscence, CSF leak and scalp necrosis are postoperative concerns. The treatment of scalp necrosis with dural and brain exposure is certainly a challenge, due to the complexity of flap techniques in such a young age. Herein we describe the use of a novel technique for the management of a scalp necrosis and dehiscence in an infant...
