RESUMEN

Buschke-Ollendorff syndrome (BOS) is a rare, often benign, autosomal skin disorder. BOS commonly presents with nontender connective tissue naevi and sclerotic bony lesions (osteopoikilosis [OPK]). Herein, we summarize the presenting features of BOS and potential associations by conducting a systematic review of the literature and summarizing a cohort seen at the Hospital for Sick Children (HSC), Toronto, Canada. PubMed was searched using the following terms: 'BOS'; 'dermatofibrosis lenticularis'; 'OPK'; 'LEMD3'; 'elastoma'; 'collagenoma'. Only case reports were included, without date or language restrictions. Cases were further narrowed to those where patients or their families had a combination of skin and bony lesions, or a positive genetic test. Data were summarized using frequencies. In total, 594 reports were discovered, of which 546 (92%) were excluded. The remaining 48 accounted for 164 cases. Skin lesions were noted in 24% of cases and bony lesions in 20%, while 54% of patients had both. In 1% of cases the diagnosis was made on genetic testing alone. A family history was noted in 92% of cases. All patients with spinal stenosis (2%) or shortened status (7%) had OPK. Six per cent of patients had neurological problems. However, 50% of the cohort from HSC had cognitive delays, and only cases from 2007 onwards reported cognitive delays (the prevalence was 17% among those cases). This review confirms the classical diagnostic features of BOS. In addition, it highlights a previously unreported association between a shortened stature and OPK, as well as a possible association with cognitive delays.

RESUMEN

This review summarizes and discusses the role and efficacy of moisturizers, particularly the more recently introduced ceramide-based formulations, in the skin care regimen of patients with both active and quiescent atopic dermatitis (AD). It is now well established that a complex interplay of environmental and genetic factors are responsible for disease onset and chronicity. Indeed, several novel genetic mechanisms have been recently discovered to be associated with AD pathogenesis. Moreover, it is increasingly recognized that the epidermal barrier plays a critical role in the initiation, perpetuation, and exacerbation of AD. The skin of patients with AD harbors several defects in epidermal barrier function, including filaggrin and ceramides. An improved understanding of these etiopathogenic factors has led to the development of topical ceramide-dominant moisturizers to replace the deficient molecules and re-establish the integrity of barrier defenses. Some of these products have demonstrated efficacy in the treatment of adult and childhood AD that are similar to mid-potency topical steroids. More importantly, they have been shown to be safe with very few associated side-effects. We recommend the addition of such new agents as both the first step of treatment and in the maintenance of clinically quiescent skin of patients with AD.
