Burns in young children: a retrospective matched cohort study of health and developmental outcomes.

BACKGROUND: Unintentional injuries are a major cause of death and disability in childhood. Most burns are unintentional, the majority occurring in pre-school children. Little is known about the outcomes of young children following burns. The purpose of this study was to examine the presenting features of burned children and compare their health and developmental outcomes with controls. METHODS: Children under 3 years admitted to the Welsh Regional Burns Centre between September 1994 and August 1997 were studied up to their sixth birthday (final data collection 2003) to ascertain the nature, course and cause of their burn. One hundred and forty-five burned children were matched with 145 controls. Their physical, psychosocial and educational health status was compared. Retrospective data were gathered from hospital notes, social services, emergency department databases, child health surveillance records and schools. RESULTS: Burns peaked at age 13-18 months were typically sustained by scalding, drink spillage and contact with hot objects. They occurred most frequently at mealtimes and 89.7% were judged to be unintentional. There was a high rate of non-attendance for follow-up - 24%. The families of children admitted with burns were more likely to have moved home than those of controls (P = 0.001). By age 6 significantly more cases were admitted to hospital with an unrelated condition (P = 0.018). There were no differences between the cases and controls in immunization status, development, school attendance and educational progress up to the age of 6 years (P > 0.05). CONCLUSIONS: We found important findings in relation to unintentional injury prevention and also noted markers that may indicate inequalities in health service utilization between cases and controls. There were no major differences between developmental and educational outcomes in the two groups.

Social health outcomes following thermal injuries: a retrospective matched cohort study.

INTRODUCTION: Over 50% of children admitted with burns are aged under 3 years. US studies suggest that up to 26% of childhood burns are non-accidental, although UK reports are lower (1-16%). OBJECTIVES: To determine the social health outcomes of burned children as regards the number of children abused, neglected or "in need" before the age of 6 years compared with matched controls. METHODS: A retrospective matched cohort study. 145 children aged under 3 years admitted for burns in 1994-1997 were matched with controls for sex, age and enumeration district and followed up until 2003. Electronic routine databases provided study data on local authority care episodes and Social Services referrals by age 6 years. RESULTS: 89.0% of cases had accidental burns and four cases (2.8%) had non-accidental burns. No case was attributed to neglect. By their sixth birthday cases were statistically more likely to have been referred to Social Services with 14 (9.7%) of the burned children having been abused or neglected versus two (1.4%) controls (95% CI 0.030 to 0.13, p = 0.004). Forty six (32%) cases versus 26 (18%) controls were defined as "in need" (95% CI 0.047 to 0.23, p = 0.006). CONCLUSION: Although most burns were deemed accidental, 2.8% were categorised as non-accidental at presentation. Almost a third of the burned children went on to be "in need". Children with a burn appear to be at higher risk of further abuse or neglect compared with controls. A burn therefore could be a surrogate marker indicating need for closer supervision and follow-up by professionals.

Monitoring trends in obesity in South Wales using routine data.

AIM: To use existing data on height and weight of 5 year old children, routinely recorded annually as part of the school entry medical, to monitor trends in obesity over the last 16 years in three South Wales localities. METHODS: Body mass index (BMI) and percentage of children over the cut off points for being overweight or obese proposed by the International Obesity Task Force were determined in 46,073 children who had height, weight, and sex recorded each school year (between 1986/87 and 2001/02) on the National Child Health Computer System held at the Swansea NHS Trust. RESULTS: With the exception of one year, the coverage for BMI measurements ranged between 87% and 99%. The accuracy of measurement and data entry was identified as suspect in some cases, and although some data entry errors could be corrected, 14% of BMI measurements were inadmissible. Logistic regression analysis of BMI trends in the remainder showed that the percentage of 5 year olds classified as overweight or obese had increased significantly over the time period and that the rate of change in girls was significantly greater than that in boys. CONCLUSION: Overweight and obese children have increased in frequency in this population. The Child Health Computer System is potentially a valuable source of information on the health status of populations and should be capable of monitoring trends in obesity. However, accuracy of measurement and data entry need to be improved, and the system, to be useful on a national basis, needs to be amalgamated at a higher level than individual NHS Trusts.

Postinfection purpura fulminans in a patient heterozygous for prothrombin G20210A and acquired protein S resistance.

Purpura fulminans usually consists of large, often symmetrical, spreading ecchymosis, which may later develop into extensive areas of skin necrosis and peripheral gangrene. Postinfectious purpura fulminans associated with an autoantibody directed against protein S has been described. The interaction and the contribution of recently described mutations such as factor V Leiden and prothrombin G20210A to the development and progression of postinfectious purpura fulminans and venous thrombosis is not known. The authors describe a patient heterozygous for prothrombin G20210A who developed purpura fulminans and extensive venous thrombosis secondary to acquired protein S deficiency.

Mucosal immunity in the urinary tract: changes in sIgA, FSC and total IgA with age and in urinary tract infection.

The incidence of primary urinary tract infection (UTI) is greatest in the first month of life and decreases with age throughout childhood. Secretory immunoglobulin A (sIgA) is an important component of mucosal immunity. The changes in secretory IgA, IgA and free secretory component (FSC) during the first year of life were examined in relation to age, sex and in infants, feeding practice. These constituents were further compared between healthy children and those with acute and recurrent UTI. Urine was collected from 41 healthy infants (16 female: 25 male) at intervals (mean age 1.4, 9.1, 44, 91, 210 and 412 days), 139 healthy children (75 female: 64 male), 29 children with histories of recurrent UTI (25 female: 4 male) and 10 with acute UTI (8 female: 2 male). sIgA, IgA and FSC were measured by enzyme linked immunoassay. In the majority of children sIgA and IgA were undetectable at birth. SIgA and IgA rose significantly during the first year then levelled off throughout childhood. FSC was detectable from birth (geometric mean [mean of logged values]-GOM at day 1.4, 362.2 ng/ml). No sex differences were apparent for any of the three constituents at any age. Breast feeding was associated with higher levels of sIgA and IgA than bottle feeding. This was highly significant at 9.1 days when sIgA and IgA levels of breast fed compared with bottle fed infants were 64.6 ng/ml vs 21.2 and 56.2 ng/ml vs 18.7 ng/ml respectively, giving a GOM ratio of 3.04 for sIgA and 3.0 for IgA (p < 0.001 for both). No significant difference in the three parameters were demonstrable when children with recurrent UTI-with normal or abnormal renal tracts-were compared with controls. Acute UTI resulted in raised sIgA, IgA and FSC compared with controls (GOM ratio of 4.9 [p < 0.002], 4.2 [p < 0.005] and 2.7 [p < 0.001] respectively). The proportion of total IgA present as sIgA (sIgA/total IgA) was not significantly different in the acute vs control groups. Urinary sIgA and IgA may be important for the observed variation with age in infant UTI and the reduced incidence in breast fed infants but does not appear to contribute to the sex associated difference in susceptibility to infection at any age.
