BACKGROUND: Actinic keratoses (AKs) prevalence was estimated at 39.5 million Americans in 2004, and the cost to treat AKs that year was approximately 1 billion dollars. Photodynamic therapy (PDT) is an FDA-approved therapy for the treatment of AK. Recent studies have focused on reducing PDT treatment time while maintaining efficacy. OBJECTIVE: To investigate the use of thermal modulation to improve the efficacy of ultra short aminolevulinic acid (ALA) incubation PDT...

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...

Lysiphlebia japonica (Ashmead) is a predominant parasitoid of cotton-melon aphids in the fields of northern China with a proven ability to effectively control cotton aphid populations in early summer. For accurate normalization of gene expression in L. japonica using quantitative reverse transcriptase-polymerase chain reaction (RT-qPCR), reference genes with stable gene expression patterns are essential. However, no appropriate reference genes is L. japonica have been investigated to date. In the present study, 12 selected housekeeping genes from L...

BACKGROUND: Actinic keratosis (AK) is a common skin disorder that can progress to invasive squamous-cell carcinoma. AK can present as clinical (visible) or sub-clinical (invisible) lesions within areas of chronic sun damage. The importance of treating sub-clinical AK is gaining support. We present a sub-analysis of a previously published Phase III, double-blind, vehicle-controlled study (NCT02289768), to assess 5-fluorouracil (5-FU) 0.5% /salicylic acid 10% treatment of sub-clinical AK lesions, based on reflectance confocal microscopy (RCM)...

Some Acanthamoeba strains are able to cause Granulomatous Amoebic Encephalitis (GAE) and Acanthamoeba keratitis (AK) worldwide because of their pathogenicity. The treatment of Acanthamoeba infections is complicated due to the existence of a highly resistant cyst stage in their life cycle. Therefore, the elucidation of novel sources of anti-Acanthamoeba agents is an urgent need. In the present study, an evaluation of the antioxidant and anti-Acanthamoeba activity of compounds in flower extracts of Tunisian chamomile (Matricaria recutita L...

The free-living amoeba (FLA) Acanthamoeba sp. is an opportunistic pathogen that can cause amoebic keratitis (AK) or granulomatous amoebic encephalitis (GAE). While current treatments of AK are long with some relapses, no consensus therapy has been developed for GAE remaining lethal in 90% of the cases. In this context, efficient antiacanthamoebal drugs have to be identified. In this work, 15 drugs used in the treatment of AK or GAE or in other parasitic diseases were evaluated for their in vitro activity on A...

PURPOSE: Flat-panel detectors on mobile C-arm (MC-arm) systems are currently challenging fixed C-arm (FC-arm) systems used in hybrid operating rooms. MC-arm systems offer an alternative to FC-arm systems in the endovascular treatment of peripheral arterial disease (PAD) but their efficiency has not been evaluated comparatively. METHODS: Two series of patients undergoing arteriography with intention to treat were included. Each series consisted of two non-randomized groups: an MC-arm group and an FC-arm group...

Actinic keratoses (AKs) are highly dynamic lesions and AK activity has been shown to be associated with squamous cell carcinoma (SCC). We sought to explore risk factors which may affect the 12-month turnover of AKs in organ transplant recipients (OTRs). The number of incident AKs, regressed AKs and net change in AK counts were calculated. Negative binomial regression and Poisson regression models were used to estimate rate ratios (RR) for these 3 outcomes. Among 150 renal and 89 liver OTRs, those who spent > 50% of a typical weekday in the sun had a lower rate of AK regression than those who spent minimal time in the sun during a typical weekday...

REVIEW
P Arenberger, M Arenbergerova
Actinic keratosis (AK) is a characteristic skin lesion on skin areas of subjects with mainly phototype I and phototype II, or with specific genetic factors and who are exposed to prolonged ultraviolet radiation. AK may be considered a precursor of in situ squamous cell carcinoma (SCC), a type of non-melanoma skin cancer (NMSC). However, it is still not possible to predict which AK lesions will develop into SCC. Early treatment of AK is therefore recommended. Despite the increasing number of patients with AK developing into SCC, to date, there is still no clear suggestion of therapeutic strategy for AK...
