INTRODUCTION: The non-invasive vulvar Paget's disease is an intra-epidermal carcinoma with glandular characteristics. It appears like an erythematous plaque. The main symptoms are pruritus and pain. The standard treatment is surgical excision in depth. This treatment is complicated with a severe morbidity and photodynamic therapy can be an alternative choice. However, the pain experienced during the photodynamic treatment of vulvar lesion is intense and leads to a premature interruption of the treatment...

Actinic keratosis (AK) is considered a premalignant form of skin cancer due to chronic sun exposure. In addition, human papilloma virus (HPV) has been advocated a role in the pathogenesis of this clinical condition. HPV proteins (mainly E6 and E7) seem to act synergistically with ultraviolet (UV) radiation in reducing the defensive mechanisms of keratinocyte apoptosis after UV damage. Data regarding the involvement of other viruses, i.e. human herpes viruses (HHV), in the pathogenesis of AK are so far controversial...

The efficacy of photodynamic therapy (PDT) with methyl aminolevulinate is reduced when treating actinic keratosis (AK) on the extremities in comparison with the face and scalp. Studies indicate that PDT efficacy can be improved by combining PDT with other treatment modalities. This randomized intra-individual study investigated whether pretreatment with topical 5% 5-fluorouracil (5-FU) enhanced the treatment efficacy of daylight-mediated PDT in 24 patients with AKs on the hands. One hand of each patient was given 7 days of pretreatment with 5-FU twice daily before daylight-PDT, whereas the other hand was treated with daylight-PDT alone...

Tretinoin is known to be a pharmaceutical drug for treating acne vulgaris, keratosis pilaris, and acute promyelocytic leukemia. In order to reveal the possible conformers of tretinoin, the energies of all the conformers through rotational bonds have been evaluated by systematic rotor search analysis. The intramolecular interactions ranging from strong hydrogen bonds to weak van der Waals forces present in tretinoin have been distinguished with the help of electron density mapping and wavefunction analysis. The global reactivity descriptors and Fukui functions of tretinoin have been calculated and discussed...

Actinic keratosis is a precursor lesion to the most common nonmelanoma skin cancer. Conventional photodynamic therapy (PDT) has been shown to be effective, but the procedure is time-consuming, can be very painful, and requires infrastructure. These shortcomings led to the emergence of daylight PDT. To obtain a global estimate of efficacy, we undertook a systematic literature review and performed a meta-analysis of the available evidence on the efficacy and safety of daylight PDT as compared to conventional PDT in the treatment of actinic keratosis and/or field cancerization...

Objective This update of the 2008 American Academy of Otolaryngology-Head and Neck Surgery Foundation cerumen impaction clinical practice guideline provides evidence-based recommendations on managing cerumen impaction. Cerumen impaction is defined as an accumulation of cerumen that causes symptoms, prevents assessment of the ear, or both. Changes from the prior guideline include a consumer added to the development group; new evidence (3 guidelines, 5 systematic reviews, and 6 randomized controlled trials); enhanced information on patient education and counseling; a new algorithm to clarify action statement relationships; expanded action statement profiles to explicitly state quality improvement opportunities, confidence in the evidence, intentional vagueness, and differences of opinion; an enhanced external review process to include public comment and journal peer review; and 3 new key action statements on managing cerumen impaction that focus on primary prevention, contraindicated intervention, and referral and coordination of care...

BACKGROUND: Photodynamic therapy (PDT) and chemical peels with trichloroacetic acid (TCA) can be applied to larger skin areas and thus are suitable treatment options for patients with multiple actinic keratosis (AK). Despite its long use TCA has, however, only been investigated rarely in this indication. OBJECTIVES: This randomized, observer-blinded, intrapatient comparison study sought to investigate the efficacy and safety of 35% TCA versus 20% aminolevulinic acid PDT (ALA PDT) in patients with extensive field cancerisation and multiple AK in the face or on the scalp...

Darier's disease (DD, keratosis follicularis: OMIM#124200) is an autosomal dominant skin disorder characterized by multiple dark brown keratotic plaques and warty papules covered by thick crusts. Most cases of DD are caused by mutations in ATP2A2, which is expressed in both the skin and the brain. ATP2A2 encodes the cardiac muscle SERCA2a protein and the ubiquitously expressed SERCA2b. SERCA2 plays an important role as a calcium pump. It is thought that a mutation in ATP2A2 causes dyskeratosis and abnormality of cell-cell adhesion...
