Ethnic differences in burn mechanism and severity in a UK paediatric population.

BACKGROUND: Burns in children are a major public health problem with long-lasting physical and psychological sequelae. Previous studies have identified that children from ethnic minorities have higher rates of burns. OBJECTIVE: The purpose of this study was to analyse the differences in paediatric burn mechanism and severity within different ethnic groups. METHODS: Demographic and burn data from all paediatric patients presenting with burn at the Burns Service, Alder Hey Children's NHS Foundation Trust, Liverpool, UK were collected over a 5 year period. RESULTS: 766 paediatric patients (age range: 7 days to 16 years old, mean: 4.5 years) were included in the study. Ethnic minority children had higher total body surface area of burn (p<0.001) and length of stay (p<0.001) compared with non-ethnic minority children. Chinese children had most burns from hot food (60%), whereas non-ethnic minority children had most burns from hot beverages (35.8%). Ethnic minority children were more deprived compared with non-ethnic minority children (Index of Multiple Deprivation 48.7 vs. 40.9; p=0.02). CONCLUSION: These results show that there are significant differences in the patterns of burns in ethnic minority groups. This data should guide targeted public health prevention and educational strategies.

Evaluation of educational methods in dermatology and confidence levels: a national survey of UK medical students.

BACKGROUND: The high prevalence of skin conditions makes dermatology education an essential part of the undergraduate medical curriculum. The aim of this study was to assess the impact of different educational methods on confidence levels in dermatology among UK medical students. METHODS: A survey-based study was carried out to establish: (i) educational experience in dermatology, and (ii) confidence levels in the British Association of Dermatologists core curriculum learning outcomes. Measures of confidence were rated using a five-point Likert scale. RESULTS: Completed questionnaires were obtained from 449 final-year medical students at 14 medical schools (12.9% of 3485 final-year UK medical students). Students who received teaching from dermatologists (P ≤ 0.01), dermatology specialist nurses (P ≤ 0.001), and expert patients (P ≤ 0.001) reported higher levels of confidence. Learning in clinical settings (P ≤ 0.001) and small-group settings (P ≤ 0.001) was associated with higher confidence levels. Student-selected components in dermatology were associated with higher confidence levels (P ≤ 0.001). Confidence levels were consistently lower in dermatological emergencies compared with chronic conditions, reflecting the lack of clinical exposure. Overall, 64.9% of students were at least adequately confident in assessing, and 52.0% were similarly confident in managing patients with skin conditions. CONCLUSIONS: The findings of this study show that specialist clinical experiences and small-group learning had the most significant influence on confidence levels in dermatology. Many medical students nearing qualification were less than adequately confident in their abilities to assess and manage skin conditions, suggesting that a greater emphasis on dermatology is required.

The influence of surgical excision margins on keloid prognosis.

Keloid disease is known to have variable clinical behavior in response to therapy and there is no clinicopathologic classification that predicts such varied behavior. The aim of this study was to study the effect of excision margins and other histopathologic characteristics on keloid prognosis.Seventy-five multiethnic patients presenting with keloid scars at a department of plastic and reconstructive surgery during an 11-year period were included in this study. Clinical data was collected and detailed histologic analyses using light microscopy were carried out on archived patient specimens.A detailed histopathologic examination of all tissue samples identified keloid border or margin characteristics which were classified into "circumscribed" (borders clearly-demarcated) and "infiltrative" (borders not clearly-demarcated and not easily-definable). The specific histologic findings were correlated with keloid recurrence which revealed that incomplete peripheral (P < 0.001) and deep excision margins (P < 0.001), as well as infiltrative borders (P < 0.05) were associated with higher 1-year reported recurrence rates.This study has given evidence that incomplete surgical excision are associated with higher recurrence and this may justify the practice of routine histopathologic reporting of keloid excision margins.
