Scoring the proliferative activity of haemangioma of infancy: the Haemangioma Activity Score (HAS).

BACKGROUND: Haemangioma of infancy (HOI) is the most frequently occurring benign tumour of infancy. A good, reliable and objective scoring system for haemangioma activity is not yet available. AIM: We have developed a simple system called the Haemangioma Activity Score (HAS) for scoring the (disease) proliferative activity of haemangiomas. The current study was undertaken to validate this system. METHODS: We validated the HAS in a comparative study of photographs taken during consultations from 2000 until 2008 (n = 78). Agreement between three observers was assessed at two different time points (t(0) and t(1)) with a minimum interval of 6 months between them, using interclass correlation coefficients (ICC). RESULTS: Agreement between observers was good. The average ICC of the HAS at t(0) and t(1) was 0.72 and 0.76, respectively. The average ICC of the HAS for the changes from baseline (HAS at t(0) minus HAS at t(1) ) was 0.69. CONCLUSIONS: We conclude that the HAS is a good system for scoring the proliferative activity of haemangiomas, and believe it to be useful in future investigations. The number of studies comparing different therapies for treating haemangiomas is steadily increasing, and the HAS (before and after treatment) may provide a valuable scoring system for evaluating such therapies.

Delayed- and immediate-type reactions in the atopy patch test with food allergens in young children with atopic dermatitis.

In recent years, the atopy patch test (APT) has been suggested as an addition in the allergological work-up of children with atopic dermatitis (AD) and suspected food allergy. We initiated a prospective clinical study in children with AD younger than 3 yr, to evaluate the additional clinical value of the APT next to our own standardized allergological work-up in case of a suspected food allergy. One hundred and thirty-five children were included in the study. They were tested using the skin application food test (SAFT), the APT and measurement of specific IgE. The allergens used in the skin tests were freshly prepared food stuffs and included commercially available cow's milk (CM), the egg white of a hard boiled hen's egg and mashed peanuts in a saline solution. Allergy was defined using a flowchart incorporating the results from the SAFT, oral challenges (OCs) and elimination and (re)introduction periods. To determine the additional value of the APT next to the SAFT, we analyzed the SAFT negative patients per allergen and used an exact binary logistic analysis to evaluate the simultaneous effects of the APT and measurement of specific IgE, calculating mutually adjusted odds ratios (ORs) for positive APTs and specific IgE levels above 0.70 U/l. We found clinically relevant food allergies in 23% (egg white) to 28% (CM and peanut) of our study population. Positive SAFT reactions were observed in 14% (peanut), 16% (egg white) and 21% (CM) of our patient population. Next to the SAFT, we did not observe a significant additional value of the APT for the diagnosis of CM or egg white allergy, but we did find a significant additional value for the diagnosis of peanut allergy (OR = 11.56; p < 0.005, 2-sided). In clinical practice this statistically significant value does not exclude the need for OC and controlled elimination and (re)introduction periods due to the presence of false-negative as well as false-positive results in the APT. In conclusion, we could not find enough support for the current addition of the APT to our standardized allergological work-up in young children below the age of 3 yr with AD and suspected food allergy. At the moment the additional value of the classical delayed-type APT next to the SAFT seems to be very limited at best in this study population and does not justify the time-consuming nature of the skin test.

A comparison of twice-daily calcipotriol ointment with once-daily short-contact dithranol cream therapy: quality-of-life outcomes of a randomized controlled trial of supervised treatment of psoriasis in a day-care setting.

BACKGROUND: Calcipotriol ointment and short-contact dithranol cream therapy are well-established topical treatments for psoriasis. Quality of life, i.e. the physical, psychological, and social functioning and well-being of the patient, has become an essential outcome measure in chronic skin disease. OBJECTIVES: To compare the quality-of-life outcomes of calcipotriol ointment with that of short-contact dithranol cream in a supervised treatment regimen, and to determine the degree of improvement in quality of life these topical treatments can accomplish. METHODS: In a multicentre randomized controlled trial in six centres in the Netherlands, 106 patients with chronic plaque psoriasis were included, 54 receiving calcipotriol ointment twice daily and 52 dithranol cream once daily in a 12-week intensive treatment programme. Patients were treated at the day-care centre, using the care instruction principle of daily visits during the first week and twice-weekly visits subsequently for up to 12 weeks. Quality of life was assessed with the Skindex-29 and the Medical Outcomes Study 36-item Short-Form General Health Survey (SF-36). RESULTS: At the end of treatment, no statistically significant differences were found between the calcipotriol and the dithranol group in any of the quality-of-life domains or scales of the Skindex-29 and the SF-36. Over time, a significant improvement of quality of life was found on all three scales of the dermatology-specific Skindex-29, predominantly of a moderate magnitude. In the calcipotriol group, a significant change of a small magnitude was found in the Physical Component Summary of the SF-36. No significant changes were found in the Mental Component Summary (or on any of the eight scales composing the questionnaire) of the SF-36. CONCLUSIONS: The hypothesis was confirmed, that no statistically significant differences in improvement of quality of life could be found between calcipotriol ointment and dithranol short-contact cream in a day-care setting. Given this result, both calcipotriol and dithranol can be welcome alternatives for the patient. Calcipotriol, being more practical and patient friendly, can be considered as a first-line approach in clinical practice. However, in patients recalcitrant to calcipotriol and/or other topical treatments, preference should be given to the dithranol regimen. Topical treatment in combination with interventions explicitly focusing on improvement of coping behaviour and psychosocial functioning may further increase the degree of improvement in the psychosocial domains of quality of life. The results of this study are likely to give further evidence to the notion that the generic SF-36 is little or not responsive to small to moderate changes in quality of life in mild to moderate psoriasis.

Practical issues on interpretation of scoring atopic dermatitis: the SCORAD index, objective SCORAD and the three-item severity score.

It is important to determine the severity of atopic dermatitis (AD) for evaluation of disease improvement after and during therapy. Scoring of the severity of AD is demanded in clinical trials. The European Task Force on Atopic Dermatitis (ETFAD) has developed the SCORAD (SCORing AD) index to create a consensus on assessment methods for AD, so that study results of different trials can be compared. However, modification of the SCORAD index has led on several occasions to wrong and incorrect use of the system. To measure the extent of AD, the rule of nines is applied on a front/back drawing of the patient's inflammatory lesions. The extent can be graded 0-100. The intensity part of the SCORAD index consists of six items: erythema, oedema/papulation, excoriations, lichenification, oozing/crusts and dryness. Each item can be graded on a scale 0-3. The subjective items include daily pruritus and sleeplessness. Both subjective items can be graded on a 10-cm visual analogue scale. The maximum subjective score is 20. All items should be filled out in the SCORAD evaluation form. The SCORAD index formula is: A/5 + 7B/2 + C. In this formula A is defined as the extent (0-100), B is defined as the intensity (0-18) and C is defined as the subjective symptoms (0-20). The maximum SCORAD score is 103. Based on training sessions by the ETFAD, the SCORAD index was modified by excluding the subjective symptoms (objective SCORAD). The objective SCORAD consists of just the extent and intensity items, the formula being A/5 + 7B/2. The maximum objective SCORAD score is 83 (plus an additional 10 bonus points). Bonus points are given for severe disfiguring eczema (on face and hands). The three-item severity (TIS) score involves the scoring of erythema (redness), oedema and excoriations (scratches) in one representative lesion, marked as R-O-S. The TIS score corresponds well with the more detailed objective SCORAD and can be used as a prescreening system or as a quick system in studies and is excellent for epidemiological studies.

Treatment of patients with atopic dermatitis using wet-wrap dressings with diluted steroids and/or emollients. An expert panel's opinion and review of the literature.

BACKGROUND: The use of dampened bandages to reduce inflamed eczema (synonyme dermatitis) is an old remedy. In order to evaluate the current indications for so-called wet-wrap treatment (WWT) for atopic dermatitis (AD), and to compare the different currently recognized methods, a group of experts critically reviewed their own expertise on WWT in respect to the existing literature on the subject. RESULTS: WWT is well tolerated in eczema due to the cooling effect on the skin and the rapid improvement in skin inflammation. It has been shown to be an extremely effective treatment for acute erythrodermic dermatitis, therapy-resistant AD and intolerable pruritus. Advantages of WWT include rapid response to therapy, reduction in itch and sleep disturbance, and potential for reduction in usage of topical corticosteroids (TCS). However, disadvantages include high cost, the necessity for special training in usage, potential for increased TCS absorption, increased cutaneous infections and folliculitis, and poor tolerability. Precautions to reduce the risks of long-term treatment should include education, monitoring of weight and height and, if necessary, serum cortisol levels. In adolescents the risk of striae from TCS absorption around puberty is high, and WWT with TCS in this age group should be used as a short-term therapy only and with extreme caution. To reduce risks, dilutions of steroids may be used ranging from 5 to 10%. In the maintenance phase this treatment can be rotated with the use of emollients only. Low potency TCS should be used on the face (with a mask). CONCLUSION: WWT using diluted steroids is a relatively safe addition to the therapeutic treatment options for children and adults with severe and/or refractory AD. Explanation and education is extremely important in the treatment of AD and WWT should only be employed by practitioners trained in its use. Specialized nursing care is essential, especially when using WWT for prolonged periods.

A comparison of twice-daily calcipotriol ointment with once-daily short-contact dithranol cream therapy: a randomized controlled trial of supervised treatment of psoriasis vulgaris in a day-care setting.

BACKGROUND: Calcipotriol has become a first-line treatment for psoriasis. Its efficacy and safety have been shown in many comparative clinical trials carried out in outpatients. In a comparative study in patients visiting the outpatient department once every 14 days, it was shown that calcipotriol was more effective and better tolerated compared with dithranol. OBJECTIVES: To compare the clinical efficacy of calcipotriol ointment with that of dithranol cream in a supervised treatment regimen. METHODS: In a multicentre randomized controlled trial in six centres in the Netherlands, 106 patients with chronic plaque psoriasis were included, 54 receiving calcipotriol ointment twice daily and 52 dithranol cream once daily. Patients were treated at the day-care centre, using the care instruction principle of daily visits during the first week and twice-weekly visits subsequently for up to 12 weeks. RESULTS: This study failed to prove that calcipotriol is as efficacious as dithranol when used in a day-care setting (noninferiority test). The mean percentage reduction in Psoriasis Area and Severity Index from baseline to end of treatment was 57.0% in the calcipotriol group vs. 63.6% in the dithranol group. However, the two-sided test for superiority indicated no statistically significant difference between the treatment groups (P = 0.39). At the end of treatment, 15% of the patients treated with calcipotriol ointment and 25% of those treated with dithranol cream did not require any further treatment. Although calcipotriol ointment appeared to be more effective during the first 8 weeks, a difference was no longer apparent at 12 weeks. In comparison with the high number of drop-outs due to cutaneous side-effects in the calcipotriol group, the frequency of a tolerable degree of irritation appeared to be higher in patients treated with dithranol. However, concomitant corticosteroid treatment of dithranol irritation in seven patients may have contributed to this difference between both treatments. Moreover, patients receiving therapy with calcipotriol ointment experienced fewer application-related skin and subcutaneous tissue disorders than patients treated with dithranol cream: 21 of 53 (40%) and 37 of 52 (71%), respectively. This difference is statistically significant (P = 0.001). CONCLUSIONS: The hypothesis that calcipotriol ointment might be at least as effective as dithranol cream in the day-care setting could not be proven in the present study. Whereas calcipotriol has become a mainstay in the routine outpatient treatment of psoriasis not requiring a day-care setting, dithranol treatment, being difficult as a routine outpatient therapy, has increased efficacy and improved tolerability if the treatment is carried out in a day-care setting.

Clobetasol propionate shampoo 0.05% and calcipotriol solution 0.005%: a randomized comparison of efficacy and safety in subjects with scalp psoriasis.

BACKGROUND: Scalp involvement in psoriatic patients represents a common issue. Treatment of the hairy skin requires adequate pharmaceutical formulations; hence, a new specific shampoo formulation of clobetasol propionate 0.05% was developed by Galderma R&D, Inc. METHODS: For this multicenter, randomized, investigator-masked, parallel group study, 151 subjects with moderate to severe scalp psoriasis were randomized to 4 weeks of treatment with clobetasol propionate shampoo or calcipotriol solution. RESULTS: Clobetasol propionate demonstrated significantly superior efficacy to calcipotriol solution (total severity score: mean difference 0.51, 95% CI 0.05-0.97, p = 0.028; global severity score: mean difference 0.43, 95% CI 0.08-0.78, p = 0.016). Adverse events were more common in the calcipotriol group than in the clobetasol propionate shampoo group. Telangiectasia and skin atrophy did not differ significantly between treatments; however, a burning sensation was significantly more common in the calcipotriol solution group. CONCLUSIONS: Short contact therapy of scalp psoriasis with this new shampoo formulation of clobetasol propionate was significantly more effective and better tolerated than calcipotriol solution for the treatment of scalp psoriasis.

Childhood discoid lupus erythematosus: report of five new cases and review of the literature.

Discoid lupus erythematosus (DLE) is an uncommon disease in childhood. In this paper we present five new cases of childhood DLE. Two of them are identical twin brothers, who developed similar lesions during an interval of 5 years. This is in favour of the hypothesis that both genetic factors and somatic mutations, due to environmental factors, are implicated in the pathogenesis. A review of the English language literature is also presented. In order to have better epidemiological data on this disease, all cases of childhood DLE, including those published in non-English literature and those not yet published, should be placed together and analysed.

Treatment of refractory atopic dermatitis using 'wet-wrap' dressings and diluted corticosteroids: results of standardized treatment in both children and adults.

BACKGROUND: 'Wet-wrap' dressings with diluted corticosteroids form an alternative treatment in patients with refractory atopic dermatitis (AD). OBJECTIVE: To evaluate a standardized treatment, using wet-wrap dressings with diluted corticosteroids, in patients with refractory AD. METHODS: Results of treatment, complications and possible side effects were retrospectively evaluated in 14 children and 12 adults. RESULTS: Skin lesions improved dramatically during 1 week of inpatient treatment. A significant decrease in early-morning serum cortisol levels was measured. Levels below the normal range were only observed after 1 week in 2 adults and on day 4 in 3 children. Suppression of the hypothalamus-pituitary-adrenal-cortex axis in 1 adult and a new exacerbation of AD in 2 children and 3 adults complicated long-term treatment at home. Additional complications included folliculitis, a Pseudomonas aeruginosa infection, a secondary bacterial infection and refractory skin lesions between bandages. CONCLUSION: Wet-wrap dressings and diluted corticosteroids form an effective treatment in patients with refractory AD.

Efficacy and safety of wet-wrap dressings in children with severe atopic dermatitis: influence of corticosteroid dilution.

BACKGROUND: The wet-wrap treatment involves emollients or corticosteroid dilutions under occlusive wet dressings, and has been reported to be highly effective in severe refractory atopic dermatitis (AD). OBJECTIVES: To investigate the influence of different corticosteroid dilutions on the efficacy and hypothalamic-pituitary-adrenal (HPA) axis suppression in children with severe refractory AD having wet-wrap dressings. METHODS: Eighteen children were treated with a 50% dilution of fluticasone propionate (FP) 0.05% cream for 2 weeks. In another five children a side-to-side comparison was conducted with 10%, 25% and 50% dilutions of FP cream under wet wrap. A third group of eight children was treated with 0% (= emollient), 5%, 10% or 25% dilutions of FP cream applied on the whole body under wet wrap. RESULTS: After 1 week, a major improvement averaging 74% was observed, without apparent differences between 5%, 10% or 25% dilutions of FP cream under wet wrap, with less improvement in the second week of treatment. The first and second group of children showed HPA axis suppression in only three of 23 children using measurements of 09.00 h serum cortisol after 2 weeks. The third group of children showed HPA axis suppression, as indicated by 06.00 h serum cortisol levels, which was related to the absolute amount of FP applied. CONCLUSIONS: This suggests that weaker corticosteroid dilutions had comparable high efficacy, but lower risk of HPA axis suppression.

Markers for early sensitization and inflammation in relation to clinical manifestations of atopic disease up to 2 years of age in 133 high-risk children.

BACKGROUND: The combination of genetic susceptibility and environmental factors induce allergic sensitization and subsequently local inflammation, resulting in atopic manifestations. OBJECTIVE: To examine whether immunological features reflecting sensitization (total and specific IgE levels, allergen-induced proliferative responses and skin tests) and markers of inflammation (plasma sE-selectin and blood eosinophils) are related to the clinical expression of atopy and whether they precede atopic disease in children up to 2 years of age. METHODS: The development of these markers during the first 2 years of life was studied prospectively in 133 newborns at high risk to develop atopic disease. RESULTS: The prevalence of atopic disease increased from 25% at 12 months to 32% at 24 months of age. The children with food allergy at 12 months, who all had atopic dermatitis (AD), turned out to have asthma-like disease in 40% and AD in 100% at the age of 24 months. Total IgE levels increased with time and from 12 months onward levels started to differ markedly between atopics and nonatopics. Food-specific IgE antibodies were significantly associated with AD (relative risk [RR] = 2.39), food (RR = 1.32) and upper-airway allergy (RR = 1.20), and house dust mite-specific IgE antibodies with upper-airway allergy (RR = 5.00). A positive skin test was significantly associated with AD (RR = 2.90) and food allergy (RR = 1.36). The inflammation markers investigated, were not related to the clinical expression or preceded atopic disease at 2 years of age in high-risk children. CONCLUSION: Positive skin tests and specific IgE to food or inhalant allergens were related to the clinical expression of different atopic diseases. The combination of AD and food allergy at 12 months reflected the strongest risk factor in this high risk cohort for the development of asthma-like disease at 24 months of age.

Treatment and pain relief of ulcerative hemangiomas with a polyurethane film.

BACKGROUND: Hemangiomas are the most common tumors occurring in young children. The most common complication in the growing phase of hemangioma is ulceration. AIM AND METHOD: We report healing, pain relief and evolutive effects of a polyurethane film in 8 cases with ulcerative hemangiomas. RESULTS: In all 8 infants, prompt pain relief and healing within 1-2 months were observed. An increased regression was also noted within 2-4 months, when the hemangiomas were in the normal proliferative phase. CONCLUSION: As far as the authors know, there is no explanation for the effectiveness of polyurethane film. Explanations could be the occlusive effects of the film inhibiting proliferation or the decrease in blood flow. As primary initial therapeutic approach in ulcerative hemangiomas, we advocate the application of a polyurethane film. This therapy is painless and suitable for children.

Scoring the severity of atopic dermatitis: three item severity score as a rough system for daily practice and as a pre-screening tool for studies.

Different scoring systems have been developed to determine the severity of atopic dermatitis. The SCORAD (SCORing Atopic Dermatitis), one of the best validated systems, is suited for clinical trials, but is too complicated and time consuming for routine clinical use. The TIS score (Three Item Severity score), a simplified system, is based on the evaluation of erythema, oedema/papulation and excoriation on a scale from 0 to 3. In order to determine the value of the TIS score we conducted a prospective study in 126 children with mild to severe atopic dermatitis. Both the TIS score and the SCORAD were assessed by trained investigators. Interobserver agreement was investigated in 20 children by comparing the independently performed scores of three investigators. A positive correlation was found between the TIS score and the SCORAD (Rank Spearman r(s)=0.86; p<0.0005). The item which correlated best with the SCORAD was excoriation (r(s)=0.72; p<0.0005) followed by oedema/papulations (r(s)=0.66; p<0.0005). Interobserver agreement which was calculated by Cohen's kappa (kappa) was "excellent" for SCORAD (kappa=0.82; p<0.001) and "fair" for TIS score (kappa=0.58; p<0.01). We conclude that the TIS score is a rough, though reliable and simple system for scoring atopic dermatitis. It is particularly suitable in general practice, for routine clinical use and for screening purposes in clinical trials. For research purposes, the objective SCORAD offers a more detailed and comprehensive assessment.
