Gyorgy Paragh, Nathalie C Zeitouni
OBJECTIVE: To evaluate the ability of two-step irradiance to maintain pain control during red light 5-aminolevulinic acid (ALA) photodynamic therapy (PDT) for actinic keratoses (AK) and assess factors influencing pain. BACKGROUND: PDT provides excellent clinical and cosmetic results in the treatment AK and early basal cell carcinomas (BCC). Widespread use of PDT is limited, in part, by pain. A two-step irradiance method for PDT has previously been shown to significantly reduce PDT-associated pain during the treatment of BCC, but the ability of this method to limit pain during the treatment of AKs has not been reported...

This split-face design study evaluated the effect of pretreatment with calcipotriol prior to daylight-mediated photodynamic therapy (DL-PDT) in patients with actinic keratosis (AK). The study included 11 subjects with grade I-III AK (mean age: 55 years). Subjects used once-daily calcipotriol 50 mcg/g ointment on half the face/scalp for 15days prior to DL-PDT. Evaluations of efficacy, safety and subject satisfaction were conducted 48hours and 7days after treatment, and at 1- and 3-month follow-ups. Three months after treatment with calcipotriol/DL-PDT and DL-PDT alone, the complete response rate was 85% and 70%, respectively...

BACKGROUND: Non-melanoma skin cancer (NMSC) and actinic keratosis (AK) are very common among fair-skinned individuals. A disease continuum from AK to squamous cell carcinoma (SCC) has been frequently postulated. AK and NMSC may influence quality of life (QL) of patients, and it can be suspected that disease progression entails a QL reduction. The purpose of this study was to document QL in patients with NMSC and AK using the health-outcome questionnaire EQ-5D-5L. METHODS: The study was designed as a non-interventional, prospective, cross-sectional study...

The purpose of the study is to describe epidemiology, clinical features, diagnosis, and treatment of Acanthamoeba keratitis (AK) with special focus on the disease in nonusers of contact lenses (CLs). This study was a perspective based on authors' experience and review of published literature. AK accounts for 2% of microbiology-proven cases of keratitis. Trauma and exposure to contaminated water are the main predisposing factors for the disease. Association with CLs is seen only in small fraction of cases. Contrary to classical description experience in India suggests that out of proportion pain, ring infiltrate, and radial keratoneuritis are seen in less than a third of cases...

Introduction: The current standard treatment for patients with Duchenne muscular dystrophy (DMD) involves corticosteroids. Granulocyte colony-stimulating factor (G-CSF) induces the proliferation of satellite cells and myoblasts and, in turn, muscle regeneration. Beneficial effects of G-CSF were also described for skeletal muscle disorders. Aim: We assessed the safety and effects of using G-CSF to promote muscle strength in patients with DMD. Materials and methods: Inclusion criteria were as follows: patients aged 5-15 years with diagnosed with DMD confirmed by genetic test or biopsy...

BACKGROUND: Actinic keratoses (AKs) are proliferations of abnormal keratinocytes, which may progress into non-melanoma skin cancers. Although multiple treatment modalities exist for AKs, their incidence continues to rise, making new methods of both prevention and treatment necessary. DNA repair enzymes have been shown to reverse sun-damage, resulting in reduced rates of AKs and non-melanoma skin cancer (NMSC) in specific patient populations. OBJECTIVE: We investigated the efficacy of a topical DNA repair enzyme lotion as a field therapy for AKs...

Exosomes are intercellular messengers with a high potential for diagnostic and therapeutic utility. It is believed that exosomes present in body fluids are responsible for providing signals which inhibit immune cells, interfere with antitumor immunity, and thus influence the response to treatment and its effect. One of the most interesting issues in exosome studies is proper addressing of their cargo composed of nucleic acids and proteins. Effective and selective isolation of extracellular vesicles and identification of proteins present in exosomes has turned out to be a challenging aspect of their exploration...
