Research projects:

Risk assessment of skin sensitizers in European Union  - PARC – Partnership for Assessment of Risk of Chemicals

Leader: Jose Hernán Alfonso (NO) & Prof. Jeanne Duus Johansen (DK). Ph.D. student: Mathias Krogh Pedersen.

Institutions: The National Allergy Center. Department of Allergy, Dermatology and Venereology, Copenhagen University Hospital, Denmark; The National Institute of Occupational Health, Norway; Department of Environmental Science, Stockholm; Swiss Centre for Applied Human Toxicology, Switzerland & Department of Dermatology, Oslo University Hospital, Oslo, Norway.

The EU project Partnership for Assessment of Risks from Chemicals - PARC - aims to promote research, share knowledge and improve methods in chemical risk assessment.

This specific project aims to investigate current regulatory practice regarding risk assessment of skin sensitizing chemicals. Information on risk assessment methods, monitoring of skin sensitizing chemicals as well as areas for improvement in current regulations and methods for risk assessment is collected and systematised. Among other things, the project will facilitate the transition to the development and use of so-called "next generation risk assessment", in order to better protect the workers' health from skin-damaging substances.

The project includes collaboration with the National Allergy Center, Gentofte Hospital, Denmark and the National Institute of Occupational Health, Norway (STAMI).

YRKESDERM – Development of an occupational dermatology outpatient clinic at Oslo University Hospital

Leader: Jose Hernán Alfonso

Participants: Ingvild Sandven, Teresa Løvold Berents, Hilde Heiro, Jan-Øivind Holm.

Institutions: Dep. of Dermatology, Oslo University Hospital (OUS), Oslo, Norway; Dep. of Occupational Medicine and Environmental Medicin, OUS; Regional Centre for Asthma, Allergy and Other Hypersensitivity, OUS & The National Institute of Occupational Health, Norway

 Work-related skin diseases are the most costly work-related diseases in Europe. Early diagnosis, crucial to avoid chronicity and work disability, requires multidisciplinary collaboration between dermatologists and occupational medicine and access to specialized tests.

We have implemented a multidisciplinary and coordinated occupational dermatology outpatient clinic with occupational medicine, a dermatologist and occupational hygienist since autumn 2022.

This polyclinic has access to highly specialized contact allergy testing and is a good interdisciplinary arena where registrars specializing in dermatology and occupational medicine can achieve all learning objectives in environmental and occupational dermatology.

The project includes cooperation with the Department of environmental and occupational medicine, OUS, Ullevål, STAMI, and with the National Allergy Center, Gentofte Hospital, Denmark

Skin sensitization from mixture exposures in atopic dermatitis

Leader: Jose Hernán Alfonso

Participants: Astrid Lossius, Teresa Løvold Berents, Steen Mollerup

Institutions: Dep. of Dermatology, Oslo University Hospital (OUS), Oslo, Norway; Dep. of Occupational Medicine and Environmental Medicine; Regional Centre for Asthma, Allergy and Other Hypersensitivity, OUS & The National Institute of Occupational Health, Norway

This project aims to explore the suitability of new approach methods and a 3D skin model to assess the risk of skin sensitization and the development of allergic contact dermatitis from mixed exposures in atopic dermatitis.

Occupational skin cancer

Leader: Jose Hernán Alfonso

Participants: Kristina Kjærheim, Jo Stenehjem,  Bendik Brinchmann, Prof. Swen Malte John, Alberto Modenese

Institutions: Dep. of Dermatology, Oslo University Hospital (OUS); The National Institute of Occupational Health, Norway; International Commission on Occupational Health & The Cancer Registry of Norway.

This project aims to the associations between occupation and risk of keratinocytes and melanocytic skin and mucosal cancers for the purposes of the recognition of skin cancer as an occupational disease and effective primary and secondary prevention.

Skin exposure assessment and occurrence of skin problems among workers recycling oil-drilling waste

Leader: Jose Hernán Alfonso

Participants: Kristine Haugen Anmarkrud, Pål Graff, Raymond Olsen, Shan Ziennoldinni, Sanja Kezic, Ivonne Jakasa.

Institutions: The National Institute of Occupational Health, Norway; University of Zagreb, Faculty of Food Technology and Biotechnology; Academic Medical Center, Amsterdam & Dep. of Dermatology, Oslo University Hospital (OUS),

This project aims to assess the exposure to occupational skin hazards, its effect on the skin barrier, and  the occurrence of skin problems among employees recycling oil-drilling waste. We will also investigate individual vulnerability mechanisms (genetic and epigenetic mechanisms) that can explain the effect of oil drilling waste on the skin barrier. The project is fully financed by STAMI and includes collaboration with Denmark, the Netherlands and Croatia.

Effects of biological exposure from the waste industry on the skin barrier

Leader: Jose Hernán Alfonso.  Post-doc: Elke Eriksen

Participants: Pål Graff, Astrid Lossius, Eva Rehbinder.

Institutions: Dep. of Dermatology, Oslo University Hospital (OUS), Oslo, Norway, The National Institute of Occupational Health, Norway & National Research Centre for the Working Environment, Danmark.

The waste industry is constantly under development to meet future demands for sustainability. This project aims to get knowledge on biological exposures when handling waste, and the changes in the skin microbiome and the skin barrier of these employees. We investigate the composition of microorganisms in the working atmosphere, in the microbiome on the skin, skin barrier function, and the occurrence of work-related skin diseases in employees of the Norwegian waste industry.

Work-related psychosocial exposures and risk of skin problems

Leader: Jose Hernán Alfonso. PhD-student:  Randi Hovden Borge

Participants:  Håkon Johannessen

Institutions: : Dep. of Dermatology, Oslo University Hospital (OUS), Oslo, Norway & The National Institute of Occupational Health, Norway

Prospective cohort study where we study the association between psychosocial exposures at work and the risk of skin problems in Norwegian workers by using data from the Survey of Level of Living – Working Conditions (Statistics Norway).
