Introduction: The purpose of this study is to explore treatment preferences and identify patient characteristics in young bio-naive adults with moderate to severe psoriasis in the Nordic countries (Norway, Finland, Sweden, and Denmark).

Methods: Patients were 18-45 years old and bio-naive but referred for biologic treatment of moderate to severe psoriasis. Patients were included at eight Nordic dermatology clinics.

Background: Atopic dermatitis (AD) is a common chronic inflammatory skin disease with high heritability. Previous genome-wide association studies have identified several loci predisposing to AD. These findings explain approximately 30% of the variance in AD susceptibility, suggesting that further work is required to fully understand the genetic underpinnings.

Introduction: Previous studies have shown that psoriasis has a significant effect on patients' health-related quality of life. The impact of psoriasis on household chores and the need for assistance with such tasks are not well documented. The aim of this study was to estimate the impact of psoriasis on the ability to carry out household chores, the time spent on skin care at home and the assistance that patients with psoriasis require with these activities.

Background: In previous studies, productivity losses have been measured specifically due to psoriasis or generally due to health problems in psoriasis patients. There is no information on the proportion of health related productivity losses that are due to psoriasis. The aim of this study was to estimate the proportion of productivity losses due to psoriasis and due to other medical problems among employed psoriasis patients.

Background: The costs of psoriasis to a tertiary-level clinic vary considerably depending on the country of study and methods used. Hospitalisation and phototherapy have been significant cost components. This study was performed to estimate the distribution and relative magnitude of the costs of psoriasis to a tertiary-level clinic.

Excessive exposure to UV radiation is the most significant known risk factor for skin cancer. Solarium devices produce UVA radiation that is 5 to 10 times stronger than that produced by the sun. All wavelengths of UV radiation cause DNA damage to skin cells and cause tanning.

Background: Psoriasis has an influence on various aspects of patients' everyday life. When estimating the total burden of the disease, the influence on leisure-time should also be taken into account.

Objectives: To evaluate the perceived impact of psoriasis on leisure-time activities.

Introduction: Psoriasis is a chronic disease, which contributes to the economic burden on health care. The distribution of psoriasis medication costs and the quality of life in these patients has been estimated to be around 20% of total costs.

Objectives: To estimate the economic distribution of medications and the impact of multiple treatment options on a patient's quality of life.

Background: The first year of infancy is crucial for the development of atopic immune response. Inadequate early Th1 and Treg responses and increased production of Th2 cytokines are associated with atopy. Breast milk contains several immunomodulatory cytokines and other factors that might influence the maturation of the infant's immune system.

Background: Previous research indicates that psoriasis has an impact on early retirement, sick leave days and reduced work performance.

Objectives: To evaluate the disadvantages at work caused by psoriasis.

Material And Methods: The sample was based on patients visiting the dermatology outpatient clinic in Turku University Hospital.

Hyposensitization alleviates the symptoms of allergic rhinitis, eye symptoms and asthma by attenuating the underlying allergic inflammation. In the treatment of hymenoptera allergy, hyposensitization may be life-saving. The need for anti-allergic medication decreases markedly with successful hyposensitization.

Polymorphic light eruption (PLE) is a common skin disorder provoked by exposure to UVR. Its clinical symptoms resemble those of a contact allergic reaction. PLE is generally considered a T-cell-mediated autoimmune reaction toward a yet unidentified antigen formed in UVR-exposed skin.

Partly similar inflammatory mediators are functioning in the disease process of psoriasis and its associated diseases. An overall improvement in patient's health status is likely to result in a better control of the comorbidities as well. Arthropathic psoriasis should be suspected, if arthritis and psoriasis occur simultaneously.

We have prospectively followed 16 Finnish xeroderma pigmentosum (XP) patients for up to 23 years. Seven patients were assigned by complementation analysis to the group XP-A, two patients to the XP-C group and one patient to the XP-G group. Six of the seven XP-A patients had the identical mutation (Arg228Ter) and the seventh patient had a different mutation (G283A).

Data on DNA repair rates of specific types of DNA lesions are very limited in humans in situ. Rate of repair of UV-induced DNA damage was followed in the skin of 17 volunteers up to 3 weeks of UV exposure, using a (32)P-postlabelling technique for the determination of specific photoproducts. The subjects of skin phototypes I and IV were exposed to 40 mJ/cm(2) of solar simulating radiation on buttock skin, and biopsies were taken at 0 h, 48 h and 3 weeks of exposure for the analysis of two cyclobutane pyrimidine dimers, TT=C and TT=T, and two 6-4 photoproducts, TT-C and TT-T, as trinucleotides.
