Per- and polyfluorinated alkyl substances (PFAS) are a group of man-made extremely persistent chemicals that have been spread worldwide since the 1950s due to their properties as effective water- and grease-repellent and heat- and temperature-resistant. They are associated with an increasing number of health effects including immune and hormonal disturbances and some types of cancer. We present a review of PFAS pollution in Denmark, the current human exposure, suspected health effects, and patient management in environmental medicine., (Published under Open Access CC-BY-NC-BD 4.0. https://creativecommons.org/licenses/by-nc-nd/4.0/.)

This review investigates the correlation between atopic dermatis and educational performance. Atopic dermatitis (AD) leads to intense itching, affecting sleep and health-related quality of life. AD negatively influences working life and poses a financial burden on society. Information about the impact of AD in childhood/adolescence on school life and the completion of education is sparse and previous studies have not found an association between AD and educational attainment. Recent studies have found AD to be associated with learning disability and decreased educational attainment. Future studies should investigate causality and the effects of optimised treatment.

Occupational hand eczema (HE) has continuously been the most frequently recognised occupational disease, comprising > 95% of all recognised occupational skin diseases. Irritant contact dermatitis constitutes > 70%, where wet work is the main eliciting factor. Knowledge on the dose-response relationship between wet work and HE is pivotal concerning preventive interventions, job counselling and medico-legal regulations, which is summarised in this review. New findings indicate a significant risk of having HE at an exposure level of no more than 30 minutes of wet work per day.

This case report describes a 55-year-old man, who was admitted to hospital with acute abdominal pain. The only positive finding was elevated levels of bilirubin and alanine transaminase and dilation of the intrahepatic bile ducts. Due to the nature of the abdominal pain acute porphyria was suspected. A urinalysis for porphyria indicated intoxication with a heavy metal, in this case lead. Lead poisoning is a rare cause of acute abdominal pain, and in this case further workup was left for the occupational health specialists, who have experience in metal intoxication.

This article presents recommendations regarding early management of patients after intake of corrosive chemicals, based on best evidence and clinical experience. Risk assessment built on clinical history, presentation and endoscopy is discussed as well as initial treatment, surgical appraisal and observation. Controversy still surrounds the need for endoscopy in asymptomatic patients, the use of computed tomography in assessing the severity of lesions as well as pharmacological treatment for preventing strictures.

Experiments have suggested reduction of neurological sequelae from carbon monoxide (CO) poisoning by treatment with hyper-baric oxygen (HBO). Randomised clinical trials have, however, been ambiguous. The discrepancy may be explained by timing of HBO relative to exposure. For other asphyxiants data are too sparse for a qualified judgement. Until more evidence is available, we suggest that HBO is used exclusively for moderate and severe CO poisoning within a time window of 12 hours.

Death cap (Amanita phalloides) is commonly found and is one of the five most toxic fungi in Denmark. Toxicity is due to amatoxin, and poisoning is a serious medical condition, causing organ failure with potential fatal outcome. Acknowledgement and clarification of exposure, symptomatic and focused treatment is of primary importance. No data from randomised, controlled trials on management exists, and there is not international consensus on treatment regime. We present amatoxin-case contacts to the Danish Poison Centre from 2006-2012 and summarize current knowledge and Danish recommendations in amatoxin poisoning management.

The use of waterproofing spray has been associated with the development of respiratory symptoms, but the pathogenetic mechanisms are unclear. We describe a case of acute respiratory disease with impaired diffusion developed after the use of a painting primer product spray (stain stop). Further investigation in aerosol-toxicology is needed.

Introduction: Lifestyle factors are important for clinical outcome. Systematic and early identification of these factors is important in order to offer relevant lifestyle intervention programmes. The objective was to evaluate whether basic registration of risk factors was understandable, applicable and sufficient in the clinical workday., Materials and Methods: Eleven clinical specialists participated from a broad range of departments. They performed identification and registration of malnutrition, overweight, physical inactivity, smoking and harmful alcohol consumption based on medical records from own departments (in total 2420 times). The specialists then evaluated the understanding, applicability and sufficiency (363 times). Their comments were noted., Results: Identification and registration was accomplished for 85% (0-100%) of the records. Except for two fields--"measurements of waist" and "other training programs"--the specialists found the basic registration understandable, applicable and sufficient. They lacked more details regarding stress-response in the information material and pointed out inconsistencies in the wording. Ten specialists found that the recommended clinical approach was possible to implement in the present routines., Conclusion: Basic registration of lifestyle factors for adult patients is possible and clinical relevant. It is recommended that the Danish National Board of Health uses the results in future.

Essential oils are used widespread by the Danish population. In Denmark a severe case of poisoning from anis oil has occurred.

The occurrence of non-specific low back pain (LBP) in 14-16-year-old adolescents has almost reached the level in adults. Among other things, the ranges of reported prevalences are wide, owing to the use of various outcome measures, questionnaire terminology, and differences in age and gender. A review of the literature points out some important possible risk factors for LBP: minimal physical activity, intensive sports, genetics, psychosocial factors, smoking and leisure-time activities with a high physical impact. However, the causal relations are not clear, and the morbidity related to non-specific LBP in adolescents has not yet been elucidated. Few intervention studies have been published, and the means of prevention have not yet been found. Research in LBP in adolescents deserves a high priority in the future to provide evidence for a relevant prevention strategy.
