RESUMO
OBJECTIVES: Juvenile localized scleroderma (JLS) is a rare condition that is often difficult to assess and for which a variety of monitoring tools have been described. We aimed to describe how monitoring tools are used and perceived by clinicians in the UK, to ascertain treatments used for JLS and to provide a description of transition arrangements to adult care. METHODS: An e-survey of UK paediatric rheumatologists and dermatologists managing children and young people (CYP) with JLS was distributed using the national organisations representing these clinician groups. We asked respondents for their views and experience using 15 JLS monitoring tools, about transition services and about treatments used. RESULTS: Thirty-five dermatologists and 13 paediatric rheumatologists responded. Paediatric rheumatologists managed more CYP with JLS than dermatologists (median 16-20 and 3, respectively). Transition arrangements were reported by 43% of dermatologists and 91% of paediatric rheumatologists. Medical photography was the most frequently regularly used monitoring tool (73% respondents). The modified Rodnan skin score was the skin score used most commonly: 33% of paediatric rheumatologists and 3% of dermatologists reported using this tool frequently. Topical treatments and ultraviolet light were used by 49-80% of dermatologists and 0-8% paediatric rheumatologists. Biologic drugs and CYC were used by 0-3% of dermatologists and 31-46% of paediatric rheumatologists. CONCLUSION: How monitoring tools are accessed, used and perceived by paediatric rheumatologists and dermatologists in the UK varies between and within clinician groups, as do treatment prescribing patterns and transition arrangements. These differences will impact on the feasibility of conducting multicentre clinical trials and on standardising clinical care.

Although port wine stains are seen in 0.3% births, widespread cutaneous capillary malformations are unusual and an association with static gliosis has not been previously reported. This is a report of a 3-year-old boy with a fixed widespread capillary naevus (port wine stain), megalencephaly and global developmental, and features of gliosis on brain magnetic resonance imaging (MRI).

Juvenile xanthogranuloma is an uncommon, benign histiocytic condition, primarily affecting children less than 1 year of age. Although usually only cutaneous lesions are found, systemic manifestations of the disease have been reported. We present a child with juvenile xanthogranuloma of the right cheek associated with contralateral cervical lymph node histiocytic infiltration.

Harlequin ichthyosis (HI) is the most severe and frequently lethal form of recessive congenital ichthyosis. Although defects in lipid transport, protein phosphatase activity, and differentiation have been described, the genetic basis underlying the clinical and cellular phenotypes of HI has yet to be determined. By use of single-nucleotide-polymorphism chip technology and homozygosity mapping, a common region of homozygosity was observed in five patients with HI in the chromosomal region 2q35. Sequencing of the ABCA12 gene, which maps within the minimal region defined by homozygosity mapping, revealed disease-associated mutations, including large intragenic deletions and frameshift deletions in 11 of the 12 screened individuals with HI. Since HI epidermis displays abnormal lamellar granule formation, ABCA12 may play a critical role in the formation of lamellar granules and the discharge of lipids into the intercellular spaces, which would explain the epidermal barrier defect seen in this disorder. This finding paves the way for early prenatal diagnosis. In addition, functional studies of ABCA12 will lead to a better understanding of epidermal differentiation and barrier formation.
