    Notes:   Topical Calcineurin Inhibitors (TCIs) used for the treatment of atopic eczema modify the immune regulatory function of the skin and may have the potential to enhance immunosuppressive ultraviolet (UV) effects. Current recommendations on UV protection in eczema patients treated with PCIs are inconsistent and have given rise to uncertainty and anxiety in patients. Therefore, the European Dermatology Forum (EDF) developed a position statement which reviews critically the available data with regard to the problem, especially analysing and commenting the limitations of rodent models for the human situation. There is no conclusive evidence from rodent trials to indicate that long-term application of TCIs is photococarcinogenic. There is a need for further studies to investigate the validity of mouse models as well as long-term cohort studies in patients using TCIs. Available data suggest that long-term application of TCIs is safe, that there is no evidence of increased skin cancer risk and that it is ethical to treat patients with TCIs when indicated.

    Notes: The term PIBI(D)S has been used to indicate a rare recessively inherited genetic disorder characterized by photosensitivity, mild non-congenital ichthyosis, brittle sulphur-deficient hair with trichoschisis (trichothiodystrophy), impaired intelligence, occasionally decreased fertility and short stature. To the best of our knowledge, about 20 cases have been reported in the literature. Here we report the characterization of the hair, brain, ultraviolet sensitivity and DNA excision repair defects of a new patient affected by PIBI(D)S. The diagnosis of PIBI(D)S syndrome was made in our patient on the basis of the clinical features and then confirmed by hair microscopy and biochemical analysis. Our patient has increased muscular tone, alteration of the deep tendon reflexes and psychomotor retardation, all consistent with hypomyelination of the brain showed by magnetic resonance imaging and computed tomography. A deficiency of DNA repair capacity was demonstrated in our patient. Furthermore, complementation analysis by cell fusion assigned our patient to xeroderma pigmentosum group D. The nucleotide excision repair defect of the other reported patients with PIBI(D)S falls generally into the same group as xeroderma pigmentosum group D and carry a mutation on the same repair gene (XPD). The relationship between these molecular characteristics and the clinical spectrum of PIBI(D)S is discussed.

    Notes: Diaminodiphenylmethane (DDM) is an aromatic diamine used in the manufacture of rubber, plastics, diisocyanates, dyes and adhesives. It may cross-react with para-(amino)compounds. Allergic patch test reactions to DDM are relatively frequent, but their relevance is often difficult to detect. We report our experience in 6809 patients (4589 female, 2220 male, mean age 39.9±17.8 years) with suspected contact dermatitis patch tested during the period 1997–1999 by the North-East Italy Contact Dermatitis Group (NEICDG). A positive patch test to DDM was detected in 132 (1.9%) patients (88 female, 44 male, mean age 49.5±16.2 years). Eczema was mostly localized on the hands. The relevance was detected in 31 patients. A logistic regression analysis showed an association with patient’s age (odds ratio 5.4 for age 30–59 years), absence of atopic diseases (odds ratio 3.1) and presence of leg ulcer (odds ratio 5). We found a highly significant correlation (p〈0.001) between sensitivity to DDM and to para-phenylenediamine, Disperse Yellow 3, cobalt chloride, fragrance mix, benzocaine, paraben mix and primin. Positive patch test results to DDM were relatively frequent. The difficulty in detecting the relevance of these sensitizations may be related to the surprisingly high frequency of concomitant positive reactions to other allergens.

    Notes: Summary We have conducted a multicentre case-control study to assess the epidemiological importance of previously suggested risk factors for psoriasis, including family history of the disease, smoking and alcohol consumption. Newly diagnosed psoriatics, with a history of skin manifestations no longer than 2 years were eligible as cases; as controls we selected subjects with newly diagnosed dermatological conditions other than psoriasis. Interviews were performed by trained medical investigators using a structured questionnaire. Two-hundred and fifteen cases, aged 16–65 years (median age 38), and 267 controls, aged 15–65 years (median age 36), were interviewed and included in the analysis. Family history was a risk factor for psoriasis; the multiple logistic regression (MLR) adjusted-odds ratio was 18.8 (95% confidence interval 6.4–54.8) for a history in parents, and 3.2 (95% confidence interval 1.5–6.6) for a history in siblings. The risk of psoriasis was higher for current smokers than for those who had never smoked. The MLR adjusted odds ratio was 2.1 (95% confidence interval 1.1–4.0) for people smoking 15 cigarettes or more per day. The risk of psoriasis was higher for alcohol drinkers: compared with teetotallers the MLR adjusted-odds ratios were 1.3 (95% confidence interval 0.8–2.3) for subjects drinking one or two drinks/day and 1.6 (95% confidence interval 0.9 to 3.0) for those drinking three or more. However, the trend in risk was not statistically significant. Our study confirms the role of family history in psoriasis and provides some evidence of a dose-response relationship for an association between smoking habits and psoriasis.

    Notes: Background Primary cutaneous follicle centre cell lymphomas (PCFCCL) are the most common type of primary cutaneous B-cell lymphomas. Patients with this disorder develop one or a few clinically indolent tumour nodules, plaques, or papules confined to a circumscribed area. Only limited data have so far been published on the use of immunoglobulin heavy chain variable region (VH) families by these tumours. Objectives Because the definition of the repertoire of VH genes could have significant biological and diagnostic implications, we evaluated a group of patients with PCFCCL for VH family use. Methods DNA obtained from 15 cases of PCFCCL was amplified by polymerase chain reaction (PCR) using a panel of VH family-specific amplimers. Results The pattern of VH family usage was similar to that reported in both normal peripheral blood B cells and the most common low grade non-Hodgkin's lymphomas, where VH region utilization is essentially random with frequent usage of the VH3 family. Conclusions These findings support the hypothesis that PCFCCL may derive from the mature peripheral lymphoid compartment. Our results may also have implications for the routine analysis of B-lymphoid clonality in PCFCCL.

    Notes: Sex hormone binding globulin (SHBG), plasma testosterone and saliva testosterone were measured in sixty-four men with androgenetic alopecia and in forty males within the same age range without alopecia. There was a significant reduction in SHBG levels in bald men, compared with controls. Plasma testosterone levels were not raised in bald men, but their salivary testosterone levels were significantly higher than in controls.Androgens play an important role in the pathogenesis of androgenetic alopecia (Ebling & Rook, 1979), but no correlation has been found between the plasma androgen level and androgenetic alopecia (Burton et al., 1979). In order to clarify this point we have studied plasma testosterone, saliva testosterone and plasma sex hormone binding globulin (SHBG) levels in a group of males with androgenetic alopecia.

    Notes: Background and aim:  Recent studies have demonstrated that contact sensitization to Compositae is not uncommon in adults. However, to our knowledge, no data are available in children. Our purpose was to investigate the prevalence of contact sensitization to Compositae in a pediatric population.Methods:  434 consecutive pediatric patients (205 M; 229 F; mean age 6,7„,,b3,4 years) with suspected allergic contact dermatitis were patch tested with 30 haptens comprising Composite mix 5%(Tenacetum volgare, Arnica montana, Partenolide, Chamomilla recutitia, Achillea millefolium) at the Dermatology Unit of the Department of Pediatrics in Padua.Results:  11 patients (7 M; 4 F; mean age 5,6„,,b2,8 years) had a positive patch test reaction to Compositae mix. In all these patients dermatitis was localized on the face and/or on the hands. Most of them had more than one positive reaction. 6 were affected by atopic dermatitis, 2 had a personal history of mucosal atopy and one had both. In 8 patients (5 with atopic dermatitis, 2 with mucosal atopy) the reaction was considered clinically relevant.Conclusion: It might be useful to add Compositae mix to the pediatric screening series, when investigating dermatitis of air-exposed areas in children with atopic diseases.

    Notes: Since January 2001, the European Surveillance System on Contact Allergies (ESSCA), supported by European Union funding (contract QLK4-CT-2001-00343), has started to collect patch-test data. This comprises a standardized clinical history and the patch-test results using the European standard series, from 17 centres in 9 European countries listed above. In 2002 and 2003, 10 511 patients' test results have been pooled and analysed. The anamnestic data partly reflect the subspecialties of some centres. The most common allergen was nickel sulfate (17.3%); however, large international variations were observed. The prevalence of contact allergy to Myroxylon pereirae resin (balsam of Peru) (5.8%) is coming close to the frequency found with the fragrance mix (6.4%). Regarding contact allergy to chromium compounds, different frequencies were noted in the 2 centres focused on occupational dermatitis (2.3% in the FIOH versus 7.4% in the Nofer Institute). These most likely reflect the beneficial effect of addition of ferrous sulfate in one, but not the other country. As differences may partly be due to different patch-test reading, standardization may need to be refined further. By providing post-marketing surveillance in the field of contact allergy, ESSCA will meet its objective of increased consumer safety across Europe.
