- Mastocytosis is a heterogeneous group of diseases defined by an increased number and accumulation of mast cells, and often also by signs and symptoms of mast cell activation. Disease subtypes range from indolent to rare aggressive forms. Mastocytosis affects people of all ages and has been considered rare; however, it is probably underdiagnosed with potential severe implications. Diagnosis can be challenging and symptoms may be complex and involve multiple organ-systems. In general it is advised that patients should be referred to centres with experience in the disease offering an individualized, multidisciplinary approach. We present here consensus recommendations from a Nordic expert group for the diagnosis and general management of patients with mastocytosis.

- Atopic dermatitis (AD) is one of the most common chronic inflammatory skin diseases in industrialized countries. To identify candidate genes involved in the pathogenesis of AD, we previously undertook a genome-wide approach using DNA microarrays. A transcript encoding the epidermal growth factor receptor (EGFR) was found to be among the down-regulated transcripts in AD skin. Here, we further investigated the expression pattern of two EGFR family members (EGFR and ErbB2) in AD skin on a protein level. Immunohistochemical (IHC) analysis of EGFR and ErbB2 showed decreased expression of EGFR and ErbB2 proteins in AD lesional skin as compared to skin from healthy individuals. Interestingly, we found that EGFR and ErbB2 were reciprocally expressed in an in vitro model of keratinocyte proliferation and differentiation, paralleling the expression patterns found in epidermis of healthy skin. The highest levels of EGFR transcripts were found in proliferating cells, while ErbB2 was found in differentiated cells. We show that blocking EGFR activity combined with co-stimulation of the Th2-cytokine IL4 in keratinocytes leads to induction of the inflammatory chemokine CCL26/eotaxin-3 in vitro. Accordingly, increased CCL26 transcriptional levels were observed in AD lesional skin. Taken together, suppression of EGFR may contribute to the pathogenesis of AD via the regulation of inflammatory chemokines.

- Objective: To identify factors associated with preserved walking ability and Katz activities of daily living (ADLs) index at 4-month and 12-month follow-up in cognitively impaired patients with femoral neck fracture. Design: Population-based cohort study. Setting: A multicenter study of the Stockholm Hip Fracture Group including 4 university hospitals. Participants: Consecutive patients (N=246) with femoral neck fracture, older than 65 years (mean, 84y; 72% women) with cognitive impairment (known dementia or low [0-2 points] score) in Short Portable Mental Status Questionnaire [0-10 points]) and able to walk before the fracture. Interventions: Not applicable. Main Outcome Measure: Walking ability and ADLs index at 4-month and 12-month follow-up. Results: Significant predictors of preserved walking ability at 12-month follow-up were discharge to rehabilitation unit (odds ratio [OR]=2.83: confidence interval [CI], 1.1-7.26; P=.03) and walking ability before the fracture (OR=8.98; Cl, 3.52-22.93; P<.001), while type of surgery was not (P=.197). Analyses were adjusted for age, sex, American Society of Anesthesiologists score, fracture type, and surgical method. Corresponding predictors of preserved Katz ADLs index at 12-month follow-up, after adjustment for age and sex, were discharge to rehabilitation unit (OR=5.33; Cl, 1.44-19.65: P=.012) and ADLs index before fracture (OR=2.5; Cl. 1.8-3.5: P<.001), while type of surgery was not (P=.376). Conclusions: Discharge to rehabilitation unit, a factor we can influence, was associated with preserved walking ability and ADLs index in cognitively impaired patients with hip fracture.

- Objectives: The results of studies of bone mineral density (BMD) in Addison's disease (AD) are inconsistent. There are no published data on hip fracture risk in patients with AD. In this study we compare hip fracture risk in adults with and without AD. Design: A population-based cohort study. Methods: Through the Swedish National Patient Register and the Total Population Register, we identified 3,219 patients without prior hip fracture who were diagnosed with AD at the age of ≥30 years during the period 1964-2006, and 31,557 age- and sex-matched controls. Time to hip fracture was measured. Results: We observed 221 hip fractures (6.9%) in patients with AD and 846 (2.7%) in the controls. Patients with AD had a higher risk of hip fracture (hazard ratio (HR) = 1.8; 95% confidence interval (CI), 1.6-2.1; p < 0.001). This risk increase was independent of sex and age at or calendar period of diagnosis. Risk estimates did not change with adjustment for type 1 diabetes, autoimmune thyroid disease, rheumatoid arthritis or coeliac disease. Women diagnosed with AD ≤50 years old had the highest risk of hip fracture (HR = 2.7; 95% CI, 1.6-4.5). We found a positive association between hip fracture and undiagnosed AD (odds ratio (OR) = 2.4; 95% CI, 2.1- 3.0) with the highest risk estimates in the last year before AD diagnosis (OR = 2.8; 95% CI, 1.8-4.2). Conclusion: Both clinically undiagnosed and diagnosed AD were associated with hip fractures, with the highest relative risk seen in women diagnosed with AD ≤50 years of age.

- Aim: To analyse serum levels of 25-hydroxyvitamin D in mothers of Somali origin and those of Swedish origin who have children with and without autism as there is a growing evidence that low vitamin D impacts adversely on brain development. Method: Four groups of mothers were invited to participate; 20 with Somali origin with at least one child with autism, 20 with Somali origin without a child with autism, 20 of Swedish origin with at least one child with autism and 20 with Swedish origin without a child with autism. Two blood samples were collected from each individual; during autumn and spring. Results: Between 12 and 17 mothers from the different groups accepted to participate, both groups of mothers of Somali origin had significantly lower values of 25-hydroxyvitamin D compared with Swedish mothers. The difference of 25-hydroxyvitamin D between mothers of Somali origin with and without a child with autism was not significant. Conclusion: Our findings of low vitamin D levels in Somali women entail considerable consequences in a public health perspective. The observed tendency, i.e. the lowest values in mothers of Somali origin with a child with autism was in the predicted direction, supporting the need for further research of vitamin D levels in larger samples of Somali mothers of children with and without autism.
