Increasing incidence of skin disorders in children? A comparison between 1987 and 2001

BACKGROUND: The increasing proportion of skin diseases encountered in general practice represents a substantial part of morbidity in children. Only limited information is available about the frequency of specific skin diseases. We aimed to compare incidence rates of skin diseases in children in general practice between 1987 and 2001. METHODS: We used data on all children aged 0–17 years derived from two consecutive surveys performed in Dutch general practice in 1987 and 2001. Both surveys concerned a longitudinal registration of GP consultations over 12 months. Each disease episode was coded according to the International Classification of Primary Care. Incidence rates of separate skin diseases were calculated by dividing all new episodes for each distinct ICPC code by the average study population at risk. Data were stratified for socio-demographic characteristics. RESULTS: The incidence rate of all skin diseases combined in general practice decreased between 1987 and 2001. Among infants the incidence rate increased. Girls presented more skin diseases to the GP. In the southern part of the Netherlands children consulted their GP more often for skin diseases compared to the northern part. Children of non-Western immigrants presented relatively more skin diseases to the GP. In general practice incidence rates of specific skin diseases such as impetigo, dermatophytosis and atopic dermatitis increased in 2001, whereas warts, contact dermatitis and skin injuries decreased. CONCLUSION: The overall incidence rate of all skin diseases combined in general practice decreased whereas the incidence rates of bacterial, mycotic and atopic skin diseases increased

Interventions for impetigo

Background Impetigo is a common, superficial bacterial skin infection, which is most frequently encountered in children. There is no generally agreed standard therapy, and guidelines for treatment differ widely. Treatment options include many different oral and topical antibiotics as well as disinfectants. This is an updated version of the original review published in 2003. Objectives To assess the effects of treatments for impetigo, including non-pharmacological interventions and 'waiting for natural resolution'. Search methods We updated our searches of the following databases to July 2010: the Cochrane Skin Group Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE (from 2005), EMBASE (from 2007), and LILACS (from 1982). We also searched online trials registries for ongoing trials, and we handsearched the reference lists of new studies found in the updated search. Selection criteria Randomised controlled trials of treatments for non-bullous, bullous, primary, and secondary impetigo. Data collection and analysis Two independent authors undertook all steps in data collection. We performed quality assessments and data collection in two separate stages. Main results We included 57 trials in the first version of this review. For this update 1 of those trials was excluded and 12 new trials were added. The total number of included trials was, thus, 68, with 5578 participants, reporting on 50 different treatments, including placebo. Most trials were in primary impetigo or did not specify this. For many of the items that were assessed for risk of bias, most studies did not provide enough information. Fifteen studies reported blinding of participants and outcome assessors. Topical antibiotic treatment showed better cure rates than placebo (pooled risk ratio (RR) 2. 24, 95% confidence interval (CI) 1.61 to 3.13) in 6 studies with 575 participants. In 4 studies with 440 participants, there was no clear evidence that either of the most commonly studied topical antibiotics (mupirocin and fusidic acid) was more effective than the other (RR 1.03, 95% CI 0.95 to 1.11). In 10 studies with 581 participants, topical mupirocin was shown to be slightly superior to oral erythromycin (pooled RR 1.07, 95% CI 1.01 to 1.13). There were no significant differences in cure rates from treatment with topical versus other oral antibiotics. There were, however, differences in the outcome from treatment with different oral antibiotics: penicillin was inferior to erythromycin, in 2 studies with 79 participants (pooled RR 1.29, 95% CI 1.07 to 1.56), and cloxacillin, in 2 studies with 166 participants (pooled RR 1.59, 95% CI 1.21 to 2.08). There was a lack of evidence for the benefit of using disinfectant solutions. When 2 studies with 292 participants were pooled, topical antibiotics were significantly better than disinfecting treatments (RR 1.15, 95% CI 1.01 to 1.32). The reported number of side-effects was low, and most of these were mild. Side-effects were more common for oral antibiotic treatment compared to topical treatment. Gastrointestinal effects accounted for most of the difference. Worldwide, bacteria causing impetigo show growing resistance rates for commonly used antibiotics. For a newly developed topical treatment, retapamulin, no resistance has yet been reported. Authors' conclusions There is good evidence that topical mupirocin and topical fusidic acid are equally, or more, effective than oral treatment. Due to the lack of studies in people with extensive impetigo, it is unclear if oral antibiotics are superior to topical antibiotics in this group. Fusidic acid and mupirocin are of similar efficacy. Penicillin was not as effective as most other antibiotics. There is a lack of evidence to support disinfection measures to manage impetigo

Effects of sulfasalazine treatment on serum immunoglobulin levels in children with juvenile chronic arthritis

This article describes the effects of sulfasalazine (SSZ) treatment on serum immunoglobulin (Ig) levels in 6 children with oligoarticular- or polyarticular onset juvenile chronic arthritis (JCA). None of the children who developed dysimmunoglobulinemia during treatment showed clinical symptoms of this adverse event, in particular none developed severe infections. All patients regained normal immunoglobulin levels after discontinuing SSZ treatment. One patient with a partial IgA deficiency at the start of SSZ treatment showed a slow increase in the IgA level during treatment. During follow-up (4-6 years), one patient spontaneously developed a dysimmunoglobulinemia and one patient developed diabetes mellitus. Based on these case reports and review of the literature we advocate monitoring of serum immunoglobulin levels while on SSZ treatment

Juvenile localized scleroderma: clinical and epidemiological features in 750 children. An international study

Objective. Juvenile localized scleroderma (JLS) includes a number of conditions often grouped together. With the long-term goal of developing uniform classification criteria, we studied the epidemiological, clinical and immunological features of children with JLS followed by paediatric rheumatology and dermatology centres.Methods. A large, multicentre, multinational study was conducted by collecting information on the demographics, family history, triggering environmental factors, clinical and laboratory features, and treatment of patients with JLS.Results. Seven hundred and fifty patients with JLS from 70 centres were enrolled into the study. the disease duration at diagnosis was 18 months. Linear scleroderma (LS) was the most frequent subtype (65%), followed by plaque morphea (PM) (26%), generalized morphea (GM) (7%) and deep morphea (DM) (2%). As many as 15% of patients had a mixed subtype. Ninety-one patients (12%) had a positive family history for rheumatic or autoimmune diseases; 100 (13.3%) reported environmental events as possible trigger. ANA was positive in 42.3% of the patients, with a higher prevalence in the LS-DM subtype than in the PM-GM subtype. Scl70 was detected in the sera of 3% of the patients, anticentromere antibody in 2%, anti-double-stranded DNA in 4%, anti-cardiolipin antibody in 13% and rheumatoid factor in 16%. Methotrexate was the drug most frequently used, especially during the last 5 yr.Conclusion. This study represents the largest collection of patients with JLS ever reported. the insidious onset of the disease, the delay in diagnosis, the recognition of mixed subtype and the better definition of the other subtypes should influence our efforts in educating trainees and practitioners and help in developing a comprehensive classification system for this syndrome.Univ Padua, Dipartimento Pediat, I-35128 Padua, ItalyAI Du Pont Hosp Children, Wilmington, de USAHosp Sick Children, Toronto, ON M5G 1X8, CanadaMayo Clin, Rochester, MN USAInst Puericultura & Pediat Martagao Gesteira, Rio de Janeiro, BrazilUniv Texas, Dept Pediat, Dallas, TX 75230 USAHosp Gen Ninos Pedro de Elizalde, Buenos Aires, DF, ArgentinaChildrens Hosp, Columbus, OH 43205 USASophia Childrens Univ Hosp, Erasmus MC, Rotterdam, NetherlandsCardinal Glennon Childrens Hosp, St Louis, MO USAUniv Kansas, Med Ctr, Kansas City, KS 66103 USAHosp Univ La Paz, Madrid, SpainUniversidade Federal de São Paulo, São Paulo, BrazilIRCCS Burlo Garofalo, Trieste, ItalyUniv São Paulo, Inst Crianca, Pompeia São Paulo, BrazilAk Eilbek, São Paulo, BrazilMeir Med Ctr, Kefar Sava, IsraelHosp Sor Maria Ludovica, Buenos Aires, DF, ArgentinaFac Med Botucatu, São Paulo, BrazilGreat Ormond St Hosp Children, London WC1N 3JH, EnglandDermatol Clin, Padua, ItalyUniversidade Federal de São Paulo, São Paulo, BrazilWeb of Scienc
