Conventional photodynamic therapy (PDT) uses red light for deeper penetration. A natural compound, aloe emodin (AE) with anticancer and photosensitising capabilities, excited by blue light, is proposed to treat superficial diseases. The photophysical properties and singlet oxygen quantum yield (ΦΔ) of AE, as well as the cytotoxic effects of AE on human cells, were investigated. The absorption and emission spectra of AE were analyzed. The ΦΔ of AE was measured by a relative method. In order to study the relationship between ΦΔ and the oxygen concentration, the dependence of ΦΔ on the oxygen concentration was investigated...

Adenoid cystic carcinoma is a rare, slow-growing neoplasm. It is most commonly located in the salivary glands, affects people older than 55 years of age, and has a predilection for women. These lesions may recur locally but have shown low metastatic potential. We present the unique case of a 71-year-old female with a nonraised hyperpigmented lesion isolated to the right heel. Confusion surrounded the clinical presentation of this dermatologic lesion, and many physicians postulated several differential diagnoses...

BACKGROUND: Atopic dermatitis is a common chronic inflammatory skin disease, affecting up to 15-30% of children in industrialized countries. As there is no definitive cure for atopic dermatitis, patients often seek other complementary therapeutic options, such as traditional Chinese medicine (TCM). TCM comprises numerous treatment modalities for the management of atopic dermatitis including acupuncture and herbal medicine. We report a case of a two and a half year old child with atopic dermatitis exacerbation treated successfully with TCM...

Modern dermatology is a reflection of the advances achieved in the general medical world. Thus, in recent years, dermatology encompasses many different fields and consequently, various subspecialties were created. In addition to dermatopathology and dermatosurgery, which are formal subspecialties, other fields of expertise include: autoimmune diseases, especially bullous diseases, hair and nail disorders, allergic diseases, infectious diseases and pigmented lesion clinics and oncodermatology. This current issue of "Harefuah" incorporates research and review articles from experts of the different subspecialties mentioned...

BACKGROUND/OBJECTIVES: Electronic medical records (EMR) can improve quality healthcare, patient safety and streamline workflow to improve efficiency of a department. Despite the known benefits and difficulties of EMR systems, there is limited data on the impact and definable effectiveness it can have within a dermatology unit. We present an outpatients' EMR known as an electronic handover system (EHS) from its inception, delivery and audit of its use in evaluating the true impact. METHODS: An audit of the EHS was conducted from 1 March to 31 August 2014...

MicroRNAs are essential regulators of various cellular processes such as cell growth, differentiation, apoptosis, and the immune response, acting as factors for translational repression and/or degradation of target messenger RNA. Currently, microRNAs are considered as promising biomarkers and therapeutic targets for different pathological conditions. Skin may serve as a convenient model for microRNA modulation studies due to the comparatively easy access to targets cells. Cutaneous diseases are characterized by multiple intercellular communication pathways, triggered by diverse stimuli and mediated by heterogenous regulators, including microRNAs...

Ipilimumab is an immunomodulatory antibody directed against cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4), which is administered to patients with advanced melanoma, with a proven positive effect on overall survival. The cutaneous adverse effects (AEs) of ipilimumab are relatively frequent, although described as usually mild and rarely life threatening. To describe a three-year experience of a single institute in detecting and managing cutaneous AEs. A cohort of patients (n = 41) treated with ipilimumab (3 mg/kg/three weeks) for metastatic melanoma, from 2013 to 2016, was investigated for adverse cutaneous events...

Infantile hemangiomas (IHs) are the most common tumors of infancy and usually follow a typical course of growth and involution. We report four soft tissue tumors that were referred to the pediatric dermatology clinic as IHs and the process by which they were diagnosed and treated. Clinicians should be aware of presentations of these uncommon, but serious soft tissue tumors. Many of these mimickers have a vastly different clinical prognosis, and early intervention to limit sequelae is crucial. Biopsy of atypical lesions should be considered early in the diagnostic process since they have varied prognosis and treatment strategies...

The use of neuromodulators for therapeutic and cosmetic indications has proven to be remarkably safe. While aesthetic and functional adverse events are uncommon, each anatomic region has its own set of risks of which the physician and patient must be aware before treatment. The therapeutic usages of botulinum toxins now include multiple specialties and multiple indications. New aesthetic indications have also developed, and there has been an increased utilization of combination therapies to combat the effects of global aging...

REVIEW
Cerrene N Giordano, Seth L Matarasso, David M Ozog
Botulinum toxin is a potentially deadly anaerobic bacterial toxin that acts by inhibiting release of acetylcholine at the neuromuscular junction, thereby inhibiting contraction of the exposed striated muscle. There are currently 4 botulinum toxin preparations approved by the US Food and Drug Administration (FDA): onabotulinumtoxin, abobotulinumtoxin, incobotulinumtoxin and rimabotulinumtoxin. While significant overlap exists, each product has unique properties and specifications, including dosing, diffusion, and storage...

Erina Lie, Sarah Sung, Steven Hoseong Yang
BACKGROUND: Acrodermatitis enteropathica (AE) is a rare dermatitis secondary to zinc deficiency most commonly seen as an inherited disease in infants. In the last decade, increased number of reports have been published on the acquired form that presents in adulthood. Unlike its inherited counterpart, acquired AE (AAE) is often secondary to underlying pathologic or iatrogenic etiologies that interfere with nutritional absorption, such as inflammatory bowel disease or alcoholism. Various gastrointestinal pathologies have been associated with AAE, but there is currently no report on its association with adult autoimmune enteropathy (AIE), a rare gastrointestinal disorder commonly seen in infants, with limited cases reported in adults...
