RESUMEN
BACKGROUND: Skin diseases are common and often have an impact on an individual's health-related quality of life. In rural communities where access to healthcare may be limited and individuals rely on farming for food and income, the impact of skin diseases may be greater. The objectives for this study were to perform an assessment of skin disease prevalence in a rural village in Laos and assess the associated impact of any skin disease found using the Dermatology Life Quality Index (DLQI). METHODS: A rural village was purposively selected and 340 participants examined by dermatologists over a four day period. Brief questionnaires were performed, followed by full body skin examinations and DLQI questionnaires completed were relevant. The data were analysed using chi square and Wilcoxon signed rank tests. RESULTS: One hundred and eighty-one participants were found to have a skin disease (53%). The six most common skin diseases were: eczema (22%), dermatophyte infections (19%), acne (10%), scabies infestation (9%), melasma (8%) and pityriasis versicolor (4%). Just over half of those with skin disease (51%) completed the DLQI, with scores ranging from 0 to 24. Those with skin problems on examination were significantly more likely to be farmers, have had a previous skin problem, be older or live in a smaller family. Conclusions This study represents the first formal documentation of skin disease prevalence in Laos and establishes the high rate of skin disease in the rural community and the associated impact these diseases have on health-related quality of life.

A 5-year-old boy from rural Afghanistan presented with a 1-year history of a skin lesion on his left knee, confirmed by polymerase chain reaction to be cutaneous leishmaniasis (Leishmania tropica). Conventional treatment of cutaneous leishmaniasis involves intravenous or intralesional pentavalent antimonials. The aim of this Critically Appraised Topic (CAT) is therefore to determine what alternative effective but less painful treatments (such as oral or topical therapies) can be used to treat cutaneous leishmaniasis in children. Embase and PubMed were searched for 'cutaneous leishmania*' AND 'treatment' AND 'children' in August 2014. All abstracts from April 2008 to August 2014 were reviewed. This search period was chosen to follow on from the Cochrane reviews on Old World and American leishmaniasis. Five randomized controlled trials met our inclusion criteria and have been included in this CAT. The study design and reporting quality in most of the trials included in both Cochrane reviews was found to be poor, and neither Cochrane review investigated the effect of patient age on response to treatment. This CAT identified two nonpainful treatments, topical paromomycin and oral miltefosine, whose effective use in children is supported in the literature. However, both of these treatments are currently unlicensed in the U.K. Our patient was successfully treated with miltefosine 20 mg twice daily for 4 weeks, leading to good resolution of the leishmaniasis plaque but with residual scarring.

BACKGROUND: Actigraphy, which uses accelerometers to record movement, has been proposed as an objective method of itch assessment in eczema. Previous studies have found strong correlations with actigraphy and video surveillance, disease severity and biological markers in patients with eczema. OBJECTIVES: To assess the validity of accelerometer data, its responsiveness to change and the practicality and acceptability of accelerometers when used as an outcome measure in a clinical trial. METHODS: This study used data collected from 336 participants of the Softened Water Eczema Trial (SWET). Accelerometer data were compared with three standardized scales: Six Area, Six Sign Atopic Dermatitis (SASSAD) severity score, Patient Oriented Eczema Measure (POEM) and Dermatitis Family Impact (DFI). Spearman's rank testing was used for correlations. RESULTS: Only 70% of trial participants had complete data, compared with 96% for the primary outcome (eczema severity - SASSAD). The convergent validity of accelerometer data with other measures of eczema severity was poor: correlation with SASSAD 0·15 (P = 0·02) and POEM 0·10 (P = 0·13). Assessing for divergent validity against quality of life measures, the correlation with the DFI was low (r = 0·29, P < 0·0001). Comparing the change scores from baseline to week 12 for SASSAD, POEM and DFI with the change in accelerometer scores we found low, negative correlations (r = -0·02, P = 0·77; r = -0·12, P = 0·06; and r = -0·01, P = 0·87, respectively). In general, the units were well tolerated but suggestions were made that could improve their usability in children. CONCLUSIONS: Actigraphy did not correlate well with disease severity or quality of life when used as an objective outcome measure in a multicentre clinical trial, and was not responsive to change over time. Further work is needed to establish why this might be, and to establish improved methods of distinguishing between eczema-related and eczema-nonrelated movements.
