Diagnostic approach to children with minor traumatic brain injury.

STUDY PURPOSE: To analyse the management of minor traumatic brain injury (MTBI) in paediatric hospitals in Germany. METHODS: An electronic survey was sent to 72 children hospitals. RESULTS: All participating (45/72; 62.5 %) hospitals had facilities to perform an electroencephalogram (EEG), 98 % cranial ultrasonography, 94 % MRI studies, and 87 % a CT scan. The initial Glasgow Coma Scale, the clinical presentation/neurological deficits, the intensity of the trauma and external/visible injuries were most important for initial assessment. The main reason for in-patient monitoring was initial clinical neurologic presentation (44 %). X-ray scans were used routinely in only 2.2 %, cMRI scans in 6.7 % and cCT scans in 13.3 %; approximately one third employed ultrasonography. In 22.2 % was an EEG part of the routine diagnostic work-up. Inpatient monitoring for 24-48 h was done in 80 %. CONCLUSIONS: Children with MTBI are often monitored clinically without resorting to potentially harmful and expensive diagnostic procedures (cCT scans).

Electroencephalogram in children with minor traumatic brain injury.

BACKGROUND: Mild traumatic brain injury (MTBI) is one of the most frequent causes for hospitalisation in childhood. Because of different guidelines in the management the diagnostic approach varies substantially. Apart from neuroimaging studies (CT, MRI, sonography) an electroencephalogram (EEG) is often performed without any evidence-based data supporting its use. METHODS: Retrospective analysis of 150 children with MTBI (age 0-16 years), who were admitted to the Children's Hospital of the University of Saarland from January 2006 to December 2007. RESULTS: Mean age was 4.3 (SD 3.6) years: 55.3% were boys. The most common mechanisms of injury were: Minor fall <1 m of height (60%) and fall >1.5 m of height (10%). The most common symptoms were: one or more episodes of vomiting (60%), somnolence (26.7%) and headache (12.7%). On 118 patients an EEG was performed; 106 (89.8%) were normal, 11 (9.3%) pathological and 1 (0.9%) invalid because of artefacts. The pathological EEGs showed focal findings with localised slowing in nine cases, spike-wave complexes in one case and general slowing in one case. Of the 11 patients with pathological EEG, two had a CT scan, two a MRI and two had cranial sonography; all the neuro-imaging was normal. None of the children required neurosurgical intervention, had a negative outcome or showed persistent symptoms. CONCLUSION: The routine performance of an EEG after MTBI in children is not indicated because in most of the cases it is unrevealing, and may lead to unnecessary diagnostic procedures. Instead, children with MTBI should be closely monitored for possible clinical complications and neurological deterioration.

Laser acupuncture in children with headache: a double-blind, randomized, bicenter, placebo-controlled trial.

To investigate whether laser acupuncture is efficacious in children with headache and if active laser treatment is superior to placebo laser treatment in a prospective, randomized, double-blind, placebo-controlled trial of low level laser acupuncture in 43 children (mean age (SD) 12.3 (+/-2.6) years) with headache (either migraine (22 patients) or tension type headache (21 patients)). Patients were randomized to receive a course of 4 treatments over 4 weeks with either active or placebo laser. The treatment was highly individualised based on criteria of Traditional Chinese medicine (TCM). The primary outcome measure was a difference in numbers of headache days between baseline and the 4 months after randomization. Secondary outcome measures included a change in headache severity using a 10 cm Visual Analogue Scale (VAS) for pain and a change in monthly hours with headache. Measurements were taken during 4 weeks before randomization (baseline), at weeks 1-4, 5-8, 9-12 and 13-16 from baseline. The mean number of headaches per month decreased significantly by 6.4 days in the treated group (p<0.001) and by 1.0 days in the placebo group (p=0.22). Secondary outcome measures headache severity and monthly hours with headache decreased as well significantly at all time points compared to baseline (p<0.001) and were as well significantly lower than those of the placebo group at all time points (p<0.001). We conclude that laser acupuncture can provide a significant benefit for children with headache with active laser treatment being clearly more effective than placebo laser treatment.
