- Questionnaire studies have indicated that patients with dental gold will more frequently have contact allergy to gold. This study aimed at investigating the relationship between contact allergy to gold and the presence and amount of dental gold alloys. A total of 102 patients were referred for patch testing because of suspicion of contact allergy. Patch tests were performed with gold sodium thiosulphate 2% and 5%. The patients underwent an oral clinical and radiological examination. Contact allergy to gold was recorded in 30.4% of the patients, and of these 74.2% had dental gold (p=0.009). A significant correlation was found between the amount of gold surfaces and contact allergy to gold (p=0.008), but there was no statistical relationship to oral lesions. It is concluded that there is a positive relationship between contact allergy to gold and presence and amount of dental gold alloys.

Journal article (peer-reviewed)abstract
- Balanoposthitis is an inflammatory disorder of the prepuce and glans penis. Microbes involved in balanoposthitis have been investigated, but no single study has covered the growth of both bacteria, Candida and Malassezia. We report here the prevalence of these microbes in 100 patients with balanoposthitis and in 26 control patients. Among patients with balanoposthitis there was a significantly higher frequency of positive cultures than in the control group (59% and 35%, respectively, p<0.05). In the balanoposthitis group Staphylococcus aureus was found in 19%, group B streptococci in 9%, Candida albicans in 18% and Malassezia in 23% of patients. In the control group S. aureus was not found at all, whereas C. albicans was found in 7.7% and Malassezia in 23% of patients. Different microbes did not correspond with distinct clinical manifestations. In summary, we report increased frequency of microbes, specifically S. aureus, in the area of the prepuce and glans penis in balanoposthitis.

- In dentistry, allergic contact dermatitis to acrylates and allergic contact urticaria to latex are important occupational hazards. There is a need to identify, non-latex gloves which are suitable for dental work but at the same time provide adequate protection against acrylate monomers. In a previous study, a new open-chamber system was used for testing the in vivo protection of 6 different gloves against an acrylate-containing ethanol-based dental adhesive. A nitrile glove gave the best protection among the gloves suitable for dental work. In the present study, the test model was used to investigate the in vivo protection of 7 non-latex gloves against a dental bonding product containing 2-hydroxyethyl methacrylate (2-HEMA) in an acetone/water vehicle. Eight 2-HEMA-allergic patients participated. Two neoprene gloves gave the best protection. The protection of the poorest glove was comparable to that of the positive control (no glove). The study produced in vivo data useful in the implementation of individual preventative measures against contact allergy to acrylates.

Loss of hyaluronan in the basement membrane zone of the skin correlates to the degree of stiff hands in diabetes patients

- Glycosaminoglycans are important components of all extracellular matrices. One of the glycosaminoglycans is hyaluronan, which is ubiquitously distributed throughout the connective tissue. Hyaluronan is especially abundant in the skin, in which it is of both structural and functional importance. This study describes the localization and distribution of hyaluronan in the skin of healthy individuals and of 23 patients with insulin-dependent diabetes mellitus and various degrees of limited joint mobility. In normal skin, hyaluronan staining was seen in all layers but most prominently in the papillary dermis and the basement membrane zone. In the skin from diabetic patients with normal or only moderately restricted mobility of the hands (limited joint mobility grades 0 and 1), the distribution of hyaluronan was similar to that of normal skin. In the skin of patients with severe restriction in joint mobility (limited joint mobility grade 2) the staining pattern was significantly different with weak hyaluronan staining in the papillary dermis and the basement membrane zone almost devoid of hyaluronan. Moreover, an increased epidermal thickness in the latter patients was evident as well as a pronounced hyaluronan staining compared with normal epidermis.

The role of vascular surgery in chronic leg ulcers: report from a specialized ulcer clinic.

Journal article (peer-reviewed)abstract
- Experience gained from cooperation between dermatologists and vascular surgeons in 177 patients evaluated at a joint leg ulcer clinic is reported. Patients were divided into two subgroups: (i) 86 patients with healed ulcers and (ii) 91 patients with ongoing therapy-resistant ulcers. Venous insufficiency was the most common etiology in both subgroups (87% and 55%, respectively). Of previous therapy-resistant ulcers, 71% were healed after the combined effort. The pattern of venous incompetence differed between the two subgroups; patients with isolated superficial disease constituting 68% and 26% of patients, respectively. In patients with therapy-resistant ulcers, those with isolated superficial venous insufficiency were found to have a better prognosis than those with deep venous insufficiency. Cooperation between the dermatologist and vascular surgeon is a mainstay in order to take advantage of the possibilities offered by modern vascular surgery.

Journal article (peer-reviewed)abstract
- Neuroectodermal syndromes involving the skin and inner ear may be associated with mutations in connexin proteins, which form gap junctions important for intercellular communication. Vohwinkel syndrome (keratodermia mutilans with hearing loss) and keratitis-ichthyosis-deafness (KID) syndrome are rare ectodermal dysplasias associated with dominant mutations in the GJB2 gene encoding connexin 26. We report here two patients, one with KID and one with Vohwinkel syndrome. Both displayed unusual clinical features and responded well to long-term treatment with oral retinoid. Mutation analysis revealed a novel GJB2 mutation p.Gly59Ser in the patient with Vohwinkel syndrome, whereas a recurrent mutation (p.Asp50Asn) was found in the patient with KID syndrome. The clinical features, particularly a proneness to skin cancer in the patient with Vohwinkel syndrome, are discussed in relation to the identified genotypes.

Does vitamin D intake during infancy promote the development of atopic allergy?
- 2009

Journal article (peer-reviewed)abstract
- The active metabolite of vitamin D, 1,25-(OH)2D3, has immunomodulatory properties in addition to its more established action on bone and calcium metabolism. Recently vitamin D has been proposed as one of several environmental factors responsible for the increase in atopic diseases during the last decades. The objective of this study was to determine whether the estimated dose of dietary vitamin D3 during the first year of life is associated with atopic diseases up to the age of 6 years. In a prospective birth cohort study 123 six-year-old children were investigated for the cumulative incidence of atopic dermatitis, allergic rhinitis or asthma by means of a postal questionnaire. Their vitamin D3 intake during infancy was recorded in a previous study and the relationship between lower or higher vitamin D3 intake and atopic illness later in childhood was assessed. Atopic manifestations were more prevalent in the group with higher intake of vitamin D3. Although small, this study supports previous investigations suggesting a role of vitamin D intake during infancy in the development of atopic allergy later in childhood. If these findings are confirmed in prospective controlled clinical trials, prevention through modified vitamin D3 supplementation in infancy could be discussed to reduce the burden of atopic illnesses.
