A non-invasive tool for skin disease diagnosis would be a useful clinical adjunct. The purpose of this study was to determine whether visible/near-infrared spectroscopy can be used to non-invasively characterize skin diseases. In-vivo visible- and near-infrared spectra (400-2500 nm) of skin neoplasms (actinic keratoses, basal cell carcinomata, banal common acquired melanocytic nevi, dysplastic melanocytic nevi, actinic lentigines and seborrheic keratoses) were collected by placing a fiber optic probe on the skin. Paired t-tests, repeated measures analysis of variance and linear discriminant analysis were used to determine whether significant spectral differences existed and whether spectra could be classified according to lesion type. Paired t-tests showed significant differences (p<0.05) between normal skin and skin lesions in several areas of the visible/near-infrared spectrum. In addition, significant differences were found between the lesion groups by analysis of variance. Linear discriminant analysis classified spectra from benign lesions compared to pre-malignant or malignant lesions with high accuracy. Visible/near-infrared spectroscopy is a promising non-invasive technique for the screening of skin diseases.

Topically applied transdermally quick penetrating (best targeting the epidermis and subsequently remaining there for a prolonged period of time) systemic independent acting, combinations and formulations which employ, combine, or incorporate a therapeutically effective non-toxic (to the patient) amount of a drug which inhibits prostaglandin synthesis together with an amount of hyaluronic acid and/or salts thereof (for example the sodium salt) and/or homologues, analogues, derivatives, complexes, esters, fragments, and/or sub units of hyaluronic acid to treat a disease and condition of the skin and exposed tissue for example, basal cell carcinoma, the precancerous, often recurrent, actinic keratoses lesions, fungal lesions, "liver" spots and like lesions (found for the most part in the epidermis), squamous cell tumours, metastatic cancer of the breast to the skin, primary and metastatic melanoma in the skin, genital warts cervical cancer, and HPV (Human Papilloma Virus) including HPV of the cervix, psoriasis (both plaque-type psoriasis and nail bed psoriasis), corns on the feet and hair loss on the head of pregnant women and remain in the skin for a prolonged period of time.

The present invention relates generally to the use of vitamin B12 (cobalamin or cyanocobalamin) alone or in combination with other photoprotective agents, including specifically other vitamins such as vitamin B9 (folic acid or folate) and vitamin B3 (niacin or niacinamide), or any chemical derivative of these vitamins and their salts, as a filter to protect cells against the damaging effects of ultraviolet (UV) light. The invention is, in one aspect, a method of reducing the rate of UV damage to cells exposed to a UV light source, by treating the cells with the vitamin composition, either alone or in combination with other photoprotective agents. Other aspects of the invention are compositions comprising effective amounts of vitamin B12 alone or in combination with other photoprotective agents including vitamin B9 and vitamin B3 and a pharmaceutically-acceptable carrier, that are useful in protecting cells, particularly skin cells, against the burning, genotoxic (mutagenic and carcinogenic), immunosuppressive and photoaging effects of UV light, especially sunlight. The invention has application as a UV light filter in oral preparations including tablets and drinks, topical creams, lotions, sprays, wipes and cosmetics. The invention also has application as a medicinal treatment for dermatological conditions caused by exposure to sunlight, such as actinic keratoses, photodermatitis, photo-induced (discoid) lupus erythematosus and the photosensitizing effects of a variety of drugs used commonly in clinical practice (e.g. certain antihistamines, ACE inhibitors, and antibiotics such as tetracycline).

Oil-in-water emulsion formulations contain both free fluorouracil and fluorouracil impregnated in porous microparticles. The formulations are suitable for topical administration, and are useful for the treatment of solar keratoses, actinic keratoses, and superficial basal cell carcinomas.

A composition of cyclodextrin and colchicine in a dermatologically acceptable cream base provided improved clearance of actinic keratoses following topical application for 1 to 3 months. The composition provides improved clearance of recalcitrant actinic keratoses. Furthermore, the treatment causes much less pain and irritation than other topical treatments for actinic keratoses.

A composition including a synergistic combination of a vitamin D3 or a derivative or precursor thereof and hyaluronic acid or derivate thereof encapsulated in a lipid based colloidal carrier system (preferably lipid based vesicles such as liposomes, niosomes, tranferosomes) and topical formulations thereof, as well as their use in the prevention and/or treatment of inflamed skin and mucous membrane, especially in the prevention and/or treatment of skin photodamage, in particular in the prevention and/or treatment of skin erythema (skin inflammation) and actinic keratosis, as well non melanoma skin cancer.

The present invention relates to methods of treating benign hyperproliferative diseases of the epidermis by administering a composition comprising at least one jasmonate ester derivative, preferably methyl jasmonate. In particular, the present invention provides jasmonate ester derivatives as potent compounds useful for the treatment of disorders such as actinic keratoses with reduced side effects.

A space for conducting photodynamic therapy (PDT) for treatment of skin diseases, especially for treatment of superficial skin tumors such as actinic keratoses, basal cell carcinomas, and initial carcinomas, wherein an active ingredient is applied to a skin area to be treated in order to form porphyrins and irradiation with light is conducted to form singlet oxygen based on the porphyrins in order to destroy diseased skin cells, wherein the space has side walls, a ceiling, and a floor, as well as at least two lighting fixtures, which are separated from one another by at least 50 cm and illuminate at least a subregion of the space, wherein there is an illuminance of at least 8,000 lux at every point in the subregion and the subregion has horizontal dimensions of at least 1 m² and a vertical height of at least 40 cm. This invention also relates to a luminous ceiling system and method for conducting PDT.

The present invention relates to a pharmaceutical composition for use in the treatment of pre-cancerous conditions of the cervix/anogenital region, non-melanoma skin cancers (NMSCs), or actinic keratosis wherein said composition comprises a surfactant, preferably an anionic or amphoteric surfactant.

The present disclosure provides a method for treating clinical or pre-clinical skin damage in a skin field of a subject, wherein the skin field has been allocated a skin cancerization field index (SCFI) score of at least 1 as determined by a process comprising the steps of: (i) assessing the number of keratoses in the skin field; (ii) assessing the thickness of the thickest keratosis in the skin field; and (iii) assessing the proportion of the field affected by clinical or subclinical skin damage. Based on the assessments made in (i), (ii) and (iii) the subject is optionally treated by at least one of (a) freezing one or more lesions, (b) shaving, curetting or surgically removing one or more lesions, (c) applying a topical treatment for actinic keratosis, basal cell carcinoma or squamous cell carcinoma, and (d) radiation therapy.

The present invention relates to novel pharmaceutical compositions for topical administration of a compound Formula I and methods of treating or preventing cancer or pre-cancerous conditions or benign hyperproliferative disorders, by administering the composition to a subject in need thereof. In particular, the present invention provides a stable formulation of active a compound of Formula I useful for the treatment of disorders such as actinic keratosis.
