BACKGROUND: Topical treatments of atopic dermatitis (AD) may be responsible for cutaneous allergies. Percutaneous sensitization to oat used in emollients/moisturizers has already been reported. Our objectives were to measure the prevalence of oat sensitization in AD children, to assess its relevance, and to look at related parameters. METHODS: We recruited prospectively children with AD referred for allergy testing between June 2001 and December 2004. Atopy patch tests (APT) and skin prick tests (SPT) to oat proteins (1%, 3% and 5%) and to the European standard series were performed followed by oral food challenge (OFC) and repeated open application test (ROAT) in the oat-sensitized group. RESULTS: About 302 children were enrolled. Oat APT and SPT were positive in 14.6% and 19.2% of cases, respectively. Children under 2 years of age were more likely to have positive APT. In oat-sensitized children, OFC and ROAT were positive in 15.6% (five of 32) and 28% (seven of 25) of cases, respectively. Thirty-two percentage of oat cream users had oat-positive atopy patch test (APT) vs 0% in the nonusers group. CONCLUSIONS: Oat sensitization in AD children seen for allergy testing is higher than expected. It may be the result of repeated applications of cosmetics with oats on a predisposed impaired epidermal barrier. We suggest avoiding topical-containing oat proteins in infants with AD.

The differential diagnosis of a midfacial mass in a child includes a great variety of tumours. Odontogenic myxoma is a benign tumour arising from the mesenchymal portion of the odontogenic apparatus that is usually seen in adolescents and adults.

INTRODUCTION: Painful bruising syndrome was described by Gardner and Diamond in 1955. It is marked by spontaneous bruising, without any biological abnormality, affecting young women with pathological mental context. EXEGESIS: We report three observations with painful bruising syndrome. In a patient, psychotherapy induced improvement in dermatological and articular manifestations. In other case, placebotherapy made clinical symptoms go away for a prolonged period. CONCLUSION: Some etiological hypotheses have been postulated for Gardner and Diamond syndrome. However, published cases speak in favour of psychogenic hypothesis. Somatic and psychological approach must be offered to these patients.
