Prospective study of community needlestick injuries.
Fifty three children were referred following community needlestick injuries, August 1995 to September 2003. Twenty five attended for serology six months later. None were positive for HIV, or hepatitis B or C. Routine follow up after community needlestick injury is unnecessary. HIV post-exposure prophylaxis should only be considered in high risk children.

Meningitis without a petechial rash in children in the Hib vaccine era.
AIMS: (1) To determine the causes of meningitis in children immunized with Hib vaccine, presenting without a non-blanching rash; (2) to review the use of dexamethasone in this group. METHOD: Retrospective review of all children with more then 10 white cells/mm(3) in their cerebrospinal fluid (CSF), admitted between January 1998 and August 2002. Children were excluded if they had a non-blanching rash on admission or if their discharge diagnosis was not meningitis. Local guidelines recommended dexamethasone to be given before antibiotics for children with meningitis and no rash. RESULTS: One hundred and eight children were identified. Causes of proven meningitis were: viral 41 (enterovirus 40), bacterial 22. CSF culture or PCR was the only diagnostic test in 31 children. Dexamethasone was given to 16 children. Length of admission was shorter in children with viral compared with bacterial meningitis (4 vs 8 days; P < 0.0001). SUMMARY: Viral meningitis is the commonest cause of meningitis without rash. Enteroviral PCR was the most useful test and needs to be widely available. Confirmation of enteroviral meningitis allowed early discharge. Few children were given dexamethasone, but only 5/108 may have benefited. CONCLUSIONS: The most common cause of meningitis without a rash in British children is enterovirus. The use of dexamethasone in children with meningitis without a rash should be reconsidered or, at least, individualised.

Best paediatric evidence; is it accessible and used on-call?
BACKGROUND: Paediatricians wanting to use evidence based medicine (EBM) strategies, need to be able to track down and critically appraise evidence. This requires access to quality filtered resources (for example, Cochrane Library), bibliographic databases (for example, Medline), and paediatric journals. AIMS: To determine whether paediatricians have access to these resources when on-call and if they use them to answer clinical questions. METHOD: A telephone survey of paediatric and neonatal units was performed during November 2001. The "paediatrician-on-call" was asked whether they could access Medline, Cochrane, and paediatric journals, and if they used these when on-call. RESULTS: Paediatric trainees were available in 87 of the 97 units contacted. All except one had access to Medline; although only 56 (64%) could do this near their ward. Eighty had access to Cochrane. Thirteen (15%) could not gain access to their library out-of-hours. All except one department had local guidelines, with 71% having >15 guidelines. Access to any of the top seven "best evidence" paediatric journals varied from 64% to 100%. Only 26% of trainees had read the evidence based section of Archives of Disease of Childhood, Archimedes. Many trainees claimed to use guidelines when on-call (61; 70%), but few used Medline (14; 16%). CONCLUSIONS: Paediatric trainees mostly have access to facilities to help them to track down and critically appraise evidence. However, few of them have used it to help make clinical decisions when on-call. Many of the doctors contacted said they used local guidelines as their source of information on-call.

Fever in returned travellers: a prospective review of hospital admissions for a 2(1/2) year period.
AIM: To identify causes of fever, treatable diseases, and the most helpful investigations in febrile children, who had travelled to the tropics or subtropics in the preceding year. METHODS: Prospective observational study of all admissions to children's wards in a district general hospital in Birmingham between January 1997 and July 1999. Children with fever >37.5 degrees C and a history of travel to the tropics or subtropics in the preceding 12 months were included. Data were available on 153/162 children; median age was 5 years (range 0.1-15). A total of 133 (85%) children had visited South Asia; only 18/135 had received malarial prophylaxis. Median time to presentation after travel was four weeks. Children were investigated with full blood count, blood film, and stool culture. Other investigations were performed at the discretion of the admitting paediatrician. RESULTS: Diarrhoeal illness (n = 41) and malaria (n = 22) were the most common diagnoses. A treatable cause for the febrile illness was identified in 70 (46%) children. One or more investigations were positive in 60% of children. Stool culture (17% positive) and blood film (14% positive) were the most helpful investigations. Platelet counts greater than 190 x 10(9)/l had a negative predictive value of 97% for malaria in this population. CONCLUSIONS: Children who present with fever and have travelled to the tropics or subtropics in the preceding year, often have a treatable infection. They should have a full blood count, blood film for malarial parasites, stool culture, blood culture, and chest x ray.

Procalcitonin as a diagnostic marker of meningococcal disease in children presenting with fever and a rash.
BACKGROUND: Procalcitonin (PCT), a precursor of calcitonin, is a recognised marker of bacterial sepsis, and high concentrations correlate with the severity of sepsis. PCT has been proposed as an earlier and better diagnostic marker than C reactive protein (CRP) and white cell count (WCC). This comparison has never been reported in the differentiation of meningococcal disease (MCD) in children presenting with a fever and rash. AIM: To determine if PCT might be a useful marker of MCD in children presenting with fever and rash. METHODS: PCT, CRP, and WCC were measured on admission in 108 children. Patients were classified into two groups: group I, children with a microbiologically confirmed clinical diagnosis of MCD (n = 64); group II, children with a self limiting illness (n = 44). Median ages were 3.57 (0.07-15.9) versus 1.75 (0.19-14.22) years respectively. Severity of disease in patients with MCD was assessed using the Glasgow Meningococcal Septicaemia Prognostic Score (GMSPS). RESULTS: PCT and CRP values were significantly higher in group I than in group II (median 38.85 v 0.27 ng/ml and 68.35 v 9.25 mg/l; p < 0.0005), but there was no difference in WCC between groups. Sensitivity, specificity, and positive and negative predictive values were higher for PCT than CRP and WCC. In group I, procalcitonin was significantly higher in those with severe disease (GMSPS >/=8). CONCLUSIONS: PCT is a more sensitive and specific predictor of MCD than CRP and WCC in children presenting with fever and a rash.
