Insulin pump therapy and the use of flash or continuous glucose monitoring in children is increasing. The diabetes devices are attached to the skin for several days to weeks with a strong adhesive, and recently, several cases of allergic contact dermatitis in children caused by components of the adhesive have been reported. In this review, we discuss such problems. The most frequent cause of allergic contact dermatitis is acrylates in the adhesive material, and the problem is serious and calls for rapid development of devices used in the treatment and monitoring of Type 1 diabetes without allergenic agents.

A recent Cochrane review evaluated the effect of topical anti-inflammatory treatment for seborrhoeic dermatitis. The authors concluded that topical steroids are an effective treatment and found some evidence of the benefit of topical calcineurin inhibitors. The existing Danish guideline for treatment of seborrhoeic dermatitis prepared on behalf of the Danish Dermatological Society recommends topical antifungal treatment as first-line treatment and anti-inflammatory treatment as adjuvant. The opinion of the authors of this article is that the results of the Cochrane review do not give rise to changes in these recommendations.

Vaccination with aluminium-adsorbed vaccines can induce aluminium allergy with persistent itching subcutaneous nodules at the injection site – vaccination granulomas. In this article we give an overview of childhood aluminium-adsorbed vaccines available in Denmark. Through literature studies we examine the incidence, the symptoms and the prognosis for the vaccination granulomas and the allergy. Finally we discuss the status in Denmark.

From July 2012, a classification code for multiple chemical sensitivity has been available in the Danish healthcare classification system. The overall purpose is to register hospital contacts in Denmark. The diagnostic code is labelled "Symptoms related to chemicals and scents", DR688A1, and classified as a subcategory to "Medically unexplained symptoms", DR688A, which is a specialization of the ICD-10 code "R68.8 Other specified general symptoms and signs". The classification was decided with reference to the present lack of scientific understanding.

Stevens-Johnson syndrome and toxic epidermal necrolysis are acute mucocutaneous diseases primarily due to drug intake. The diseases are characterised by the separation of epidermis from dermis which can be life-threatening. Mortality is often caused by sepsis and multiple organ failure. The most common drugs involved are antibiotics, antiepileptic medicine, allopurinol and nonsteroidal anti-inflammatory drugs. Besides withdrawing the suspected drug the treatment is mainly symptomatic. A number of systemic treatments have been suggested including systemic corticosteroids, intravenous immunoglobulins, cyclosporine, granulocyte colony stimulating factor and tumour necrosis factor-alpha inhibitors although they remain controversial.

Psoriasis is a chronic inflammatory skin disease with a global prevalence of 2-3%. In recent years it has been established that patients with psoriasis carry an increased risk of type 2 diabetes, but the underlying pathophysiological mechanisms remain unclear. The association is most likely due to a combination of shared genes, immunoinflammatory mechanisms and a number of diabetes risk factors in patients with psoriasis. The current review summarises the evidence in the field and calls for attention on diabetes risk assessment, preventive measures and treatment in patients with psoriasis.

This article reviews if local immunosuppression of atopic dermatitis is associated with an increased risk of cancer - as implicated by a warning issued by the FDA and EMEA health authorities because systemic immunosuppression of transplanted patients leads to a significant increase of non-melanoma skin cancer and lymphoma. So far, no studies support that the use of topical immunosuppression increases the risk of local or systemic cancer.

An increasing number of patients undergo soft-tissue augmentation. The quality depends on the applied filler substance, the compliance of the patient and the physician. Long-term adverse reactions are referred to as nodules or granulomas. Nodules following degradable gels and polyacrylamide hydrogel are always caused by bacteria. Nodules following inert, hydrophobic silicone gel and combination gels may emerge years after the injection. They are often caused by a low-grade infection with ensuing enhanced fibrosis and treatment requires a specialist.
