P Mendes-Bastos, R Macedo, R Duarte
Hidradenitis suppurativa (HS) is a chronic, recurrent and debilitating skin disease of the hair follicle that is accompanied by systemic inflammation. Treating HS is challenging, and therapeutic tools as diverse as topical and systemic antibiotics, biologics, intralesional steroids, surgical procedures or light and laser therapies are frequently needed. The combination of oral clindamycin and rifampicin (R+C) has been suggested as a possible treatment regimen (level of evidence III, strength of recommendation C)...

Mahmoud A Sliem, Rania A Karas, M A Harith
A new ascorbic acid (AA) nanocomposite with low toxicity and high photo and thermal stability is constructed for certain dermatological applications in humans. The presented nanocomposite consists of AA, nano-hydroxyapatite (nHAp) and carboxymethyl cellulose (CMC). The physicochemical properties of such CMC-nHAp-AA nanocomposite were characterized using X-Ray diffractometery (XRD), Fourier Transform Infra-Red (FTIR), Energy Dispersive X-ray (EDX) and UV-VIS spectroscopies. The size and morphology of the synthesized nanocomposites were characterized by TEM/SEM techniques...

Brief exposure of skin to near-infrared (NIR) laser light has been shown to augment the immune response to intradermal vaccination and thus act as an immunologic adjuvant. Although evidence indicates that the NIR laser adjuvant has the capacity to activate innate subsets including dendritic cells (DCs) in skin as conventional adjuvants do, the precise immunological mechanism by which the NIR laser adjuvant acts is largely unknown. In this study we sought to identify the cellular target of the NIR laser adjuvant by using an established mouse model of intradermal influenza vaccination and examining the alteration of responses resulting from genetic ablation of specific DC populations...

The facial-cervical scars bring the suffering to the patients both physically and mentally. Choosing a proper donor soft tissue is always one of the critical issues, especially to Asian patients. Among the common used donor sites, the deltopectoral site was conceived as the most suitable donor tissue for the reconstruction in face and neck for its adjacent site and match in color and texture. There were 220 patients with facial-cervical scars reconstructed by the pedicled expanded deltopectoral flap between 2007 through 2015 in the authors' hospital...

Kanheng Zhou, Nhan Le, Zhihong Huang, Chunhui Li
Elastography has the ability of quantitatively evaluating the mechanical properties of soft tissue, thus is helpful for diagnosis and treatment monitoring for many diseases, e.g. skin diseases. Surface acoustic waves (SAWs) have been proven to be a non-invasive, non-destructive method for accurate characterization of tissue elastic properties. Current surface acoustic wave elastography using high energy laser pulse or mechanical shaker still have some problems. In order to improve SAW elastography in medical application, a new technique was proposed in this paper, which combines high intensity focused ultrasound (HIFU) as a SAWs impulse inducer and PhS-OCT as a SAWs detector...

A lipase-sensitive singlet oxygen-producible and erythromycin-loaded liposome (LSSPL) was developed for combination antibacterial therapy for skin disorder. The LSSPL was synthesized by coating pullulan-pheophorbide a (PU-Pheo A) conjugates onto erythromycin-loaded liposomes composed of 1,2-dipalmitoyl-sn-phosphatidylcholine (DPPC) and cholesterol. Lipase activity was chosen as the environmental-stimulus for the controlled release of erythromycin and Pheo A from LSSPL because skin inflammation-inducing Propionibacterium acnes (P...

Partial unilateral lentiginosis (PUL) is an unusual pigmentary disorder characterized by numerous lentigines grouped within an area of normal skin. Although treatment is not necessary, many patients with facial PUL seek medical help for cosmetic reasons. There is no established standard treatment for PUL. Conventional lasers may cause postinflammatory hyperpigmentation because keratinocytes are injured during the process. Also, scarring, long downtime, and pain are important issues. A 19-year-old patient with facial PUL was successfully treated with low-fluence 1,064-nm Q-switched neodymium-doped yttrium aluminum garnet (QS Nd:YAG) laser...

Ablative fractional lasers (AFXL) enhance uptake of therapeutics and this newly emerging field is called laser-assisted drug delivery (LAD). This new science has emerged over the past decade and is finding its way into clinical practice. LAD is poised to change how medicine delivers drugs. Topical and systemic application of pharmaceutical agents for therapeutic effect is an integral part of medicine. With topical therapy, the stratum corneum barrier of the skin impairs the ability of drugs to enter the body...

Study of skin penetration and distribution of the drug compounds in the skin is a major challenge in the development of topical drug products for treatment of skin diseases. It is crucial to have fast and efficacious screening methods which can provide information concerning the skin penetration and the distribution of the drug molecules in the region of the target. Mass spectrometry imaging (MSI) such as matrix-assisted laser desorption/ionization (MALDI)-MSI offers the opportunity to analyze the drug distribution at micrometer scale, but is a low throughput technique...

OBJECTIVE: Insulin increases glucose disposal in part by enhancing microvascular blood flow (MBF) and substrate delivery to myocytes. Insulin's microvascular action is impaired with insulin resistance and type 2 diabetes. Resistance training (RT) improves glycemic control and insulin sensitivity, but whether this improvement is linked to augmented skeletal muscle microvascular responses in type 2 diabetes is unknown. RESEARCH DESIGN AND METHODS: Seventeen (11 male and 6 female; 52 ± 2 years old) sedentary patients with type 2 diabetes underwent 6 weeks of whole-body RT...

The accuracy of images obtained by Diffuse Optical Tomography (DOT) could be substantially increased by the newly developed time resolved (TR) cameras. These devices result in unprecedented data volumes, which present a challenge to conventional image reconstruction techniques. In addition, many clinical applications require taking photons in air regions like the trachea into account, where the diffusion model fails. Image reconstruction techniques based on photon tracking are mandatory in those cases but have not been implemented so far due to computing demands...

Previous studies have discussed an inverse correlation between age and wound healing, because it relates to the association of aging with a gradual decrease in healing capacity. Treatment with photobiomodulation therapy (PBMT) improves wound healing by inducing increases in mitotic activity, numbers of fibroblasts, collagen synthesis, and neovascularization. Therefore, this study aimed to evaluate the effects of PBMT in cutaneous wound healing in aged rats. A punch biopsy of 8 mm in diameter was performed to produce a skin wound...
