A new surgical tape with a mesh designed to prevent skin tears and reduce pain during tape removal.

We devised a surgical tape that prevents skin tears while maintaining adhesive strength. Under the assumption that microscopic damage to the skin is reflected in pain felt on the skin, we statistically analyzed skin pain when the tape was peeled off to show the skin protection effect of the mesh on the new tape. This tape has a three-layer structure consisting of a tape substrate, adhesive, and mesh.

Carbon monoxide combined with artificial blood cells acts as an antioxidant for tissues thermally-damaged by dye laser irradiation.

Artificial red blood cells [i.e., hemoglobin vesicles (HbVs)] can be used as photosensitizers in pulsed-dye laser (PDL) treatment for port wine stains in animal models.

Efficacy and Safety of Propranolol Gel for Infantile Hemangioma: A Randomized, Double-Blind Study.

We aimed to evaluate the efficacy and safety of propranolol gel at various concentrations with infantile hemangiomas after proliferative phases. We designed a single-center, randomized, double-blind, dose-dependent trial with placebo control and randomized patients to receive propranolol gel at 0, 1, or 5%, twice daily for 24 weeks. The primary efficacy endpoint was the percentage change in redness of the tumors.

Artificial red blood cells increase large vessel wall damage and decrease surrounding dermal tissue damage in a rabbit auricle model after subsequent flashlamp-pumped pulsed-dye laser treatment.

Artificial red blood cells (i.e. hemoglobin [Hb] vesicles [Hb-Vs]) function effectively as photosensitizers in flashlamp-pumped pulsed-dye laser (PDL) treatment for port-wine stains in animal models.

Japanese clinical practice guidelines for vascular anomalies 2017.

The objective was to prepare guidelines to perform the current optimum treatment by organizing effective and efficient treatments of hemangiomas and vascular malformations, confirming the safety, and systematizing treatment, employing evidence-based medicine (EBM) techniques and aimed at improvement of the outcomes. Clinical questions (CQs) were decided based on the important clinical issues. For document retrieval, key words for literature searches were set for each CQ and literature published from 1980 to the end of September 2014 was searched in Pubmed, Cochrane Library, and Japana Centra Revuo Medicina (JCRM).

Evaluation of pain incidence due to venous malformation based on data from 85 institutions in Japan.

Background: Depending on the size and site of the venous malformation (VM), patients with VM often experience pain and swelling. VMs in the head and neck typically have lower pain rates due to complications than VMs in the limbs and trunk. We evaluated the heuristics on VM pain by statistically analyzing data of patients with VM from a multicenter database in Japan.

The beneficial effect of traditional Japanese herbal (Kampo) medicine, Hochu-ekki-to (Bu-Zhong-Yi-Qi-Tang), for patients with chronic wounds refractory to conventional therapies: A prospective, randomized trial.

Hochu-ekki-to (HET) is a traditional Japanese herbal (Kampo) medicine for the treatment of severe weakness, loss of appetite, and indigestion in elderly patients and for the prevention of opportunistic infections. The impact of HET on patients with chronic wounds refractory to conventional therapies was investigated in a prospective, randomized trial, including 18 patients divided into medication (7.5 g oral HET per day, n = 9) and control (n = 9) groups.

Intravenous injection of artificial red cells and subsequent dye laser irradiation causes deep vessel impairment in an animal model of port-wine stain.

Our previous study proposed using artificial blood cells (hemoglobin vesicles, Hb-Vs) as photosensitizers in dye laser treatment for port-wine stains (PWSs). Dye laser photons are absorbed by red blood cells (RBCs) and hemoglobin (Hb) mixture, which potentially produce more heat and photocoagulation and effectively destroy endothelial cells. Hb-Vs combination therapy will improve clinical outcomes of dye laser treatment for PWSs because very small vessels do not contain sufficient RBCs and they are poor absorbers/heaters of lasers.

Artificial Red Blood Cells as Potential Photosensitizers in Dye Laser Treatment Against Port-Wine Stains.

We suggest a novel method that uses artificial blood cells (hemoglobin vesicles, Hb-Vs) as photosensitizers in dye laser treatment (at 595-nm wavelength) for port-wine stains (i.e., capillary malformations presenting as red birthmarks) based on the results of animal experiments.

Photosensitizer Effects of Artificial Red Cells on Dye Laser Irradiation in an Animal Model Assuming Port-Wine Stain Treatment.

Background: The complete removal of port-wine stains has remained challenging. Based on the principle of treating port-wine stains with a dye laser, intravenous injection of artificial red cells (hemoglobin vesicles) immediately before laser treatment might improve the clinical outcome of the therapy. The hemoglobin vesicle injection increases the hemoglobin concentration in microvessels.

Hyperpigmentation after surgery for a deep dermal burn of the dorsum of the hand: partial-thickness debridement followed by medium split-thickness skin grafting vs full-thickness debridement followed by thick split-thickness skin grafting.

Background: Early excision and skin grafting are commonly used to treat deep dermal burns (DDBs) of the dorsum of the hand. Partial-thickness debridement (PTD) is one of the most commonly used procedures for the excision of burned tissue of the dorsum of the hand. In contrast, full-thickness debridement (FTD) has also been reported.

Reconstruction of the great toe using a pedicled medial plantar flap with anterograde venous drainage.

Background: Reconstruction of the great toe defect is difficult. The most distal point of the rotation arc of a retrograde-flow medial plantar flap is the plantar side of the proximal phalanx. The purpose of this report was to present a new procedure that extends the rotation arc of this flap.

Static reconstruction of malar region in facial paralysis: a new alternative technique for plasty of symmetric mouth appearance.

Static suspension using fascia lata graft is used as a reconstructive procedure against drooping of the mouth corner for treating longstanding facial paralysis. Although it achieves symmetry at rest, movement of the mouth corner at mouth opening is restricted to some extent because it is fixed with fascia lata to the immovable temporal fascia, the parotid fascia, or bones. This was overcome by suspending the mouth corner to the mandibular coronoid process with fascia lata, which enabled a shift of the mouth corner with mouth opening and closure.

Descending branch of the perforating branch of the peroneal artery perforator-based island flap for reconstruction of the lateral malleolus with minimal invasion.

Background: Reconstruction of intractable ulcers on the lateral malleolus is challenging because affected patients suffer various complications. A lateral supramalleolar flap, nourished by the superficial cutaneous branch of the perforating branch of the peroneal artery, has been described as one of the most reliable methods for reconstructing this difficult region. Although the deep descending branch of the perforating branch of the peroneal artery has a tiny cutaneous perforator, a flap based on this perforator has not been described.

Early diagnosis and risk factors for lymphedema following lymph node dissection for gynecologic cancer.

Background: Although early diagnosis is important for selecting an effective surgical treatment for secondary lymphedema, an efficient screening test for detecting early-stage lymphedema has not yet been established. Serial changes of lymphatic function before and after lymph node dissection and risk factors for secondary lymphedema are important indicators.

Methods: A prospective cohort observational study was conducted with 100 consecutive gynecologic cancer patients who underwent pelvic lymph node dissection.

Reconstruction of a fingertip with a thenar perforator island flap.

We raised thenar island flaps that were supplied by perforators that originated in the superficial palmar arch or the superficial palmar branch of the radial artery for the reconstruction of fingertip defects in eight patients. The flap was so well-vascularised that a large flap with increased mobility could be raised. The donor site was covered with well-vascularised thick tissue, and skin grafting of the donor site was avoided in all cases.

Association between plate location and plate removal following facial fracture repair.

Background: Titanium-based plates used to repair facial fractures are sometimes removed despite their high biocompatibility. Local discomfort can lead to plate removal surgery. Local discomfort may differ according to patient characteristics, tissue properties and plate thickness; however, little is known about the relationship between these conditions and plate removal.

Treatment of velopharyngeal inadequacy in a patient with submucous cleft palate and myasthenia gravis.

Objective: To describe the clinical course and management of a patient with submucous cleft palate who developed myasthenia gravis (MG) as an adult and suffered recurrent hypernasality. Few reports have described MG patients undergoing pharyngeal flap surgery for velopharyngeal incompetence, and these have described only slight speech improvement in such patients.

Design: Case report.

Low-dose GH supplementation reduces the TLR2 and TNF-alpha expressions in visceral fat.

The increased population of TLR2/TNF-alpha co-expressing adipocytes is associated with the development of insulin resistance. We have herein shown the significance of low-dose growth hormone (GH) supplementation for the regulation of TLR2 and TNF-alpha expressions in visceral fat using different kinds of mouse models fed with a high-fat diet. Low-dose GH supplementation reduced the increased population of TLR2/TNF-alpha co-expressing adipocytes in high-fat fed mice.
