Clinical Trial
Pharmacokinetics of piritramide in newborns, infants and young children in intensive care units.
Piritramide is indicated for treatment of postoperative pain and analgosedation in the intensive care unit (ICU) setting. In an open prospective study the pharmacokinetics of piritramide were investigated in four groups: newborns (NB, age: 1-28 days) (n=8), infants 1 (IF1, age: 2-4 months) (n=7), infants 2 (IF2, age: 5-12 months) (n=14) and young children (YC, age: 2-4 years) (n=10). The recommended paediatric dose range for therapy of postoperative pain is 50-200 microg/kg. ⋯ Therefore, dosage needed to treat postoperative pain should be reduced, and the repetitive doses should be geared to the analgesic effects. In infants and young children the elimination of piritramide is increased compared to adults; therefore the duration of the effects of piritramide will be shortened, and dose intervals ought to be reduced. Subsequent clinical trials for detailed dose adjustment of piritramide in paediatric patients comparing pharmacokinetics and effectiveness are needed.

Multicenter Study
Predictors of intracranial injuries in children after blunt head trauma.
This study was conducted to determine if clinical features can predict the risk of intracranial injury (ICI) in pediatric closed head trauma. We enrolled 3,806 children under 16 years consecutively referred for acute closed head trauma to the paediatric emergency room of five Italian children's hospitals. Relevant outcomes were death and diagnosis of ICI. Clinical symptoms and signs were evaluated as possible outcome predictors. Children were also classified into five groups according to their clinical presentation. The association of ICI with signs and symptoms and the appropriateness of the five-group classification in predicting the likelihood of ICI were evaluated by logistic regression analyses. ICI was diagnosed in 22 children; 2 of them died. The risk of fatal and nonfatal ICI was 0.5 and 5.2 per 1,000 children with closed head trauma respectively. Significant associations were found between ICI and loss of consciousness, prolonged headache, persistent drowsiness, abnormal mental status, focal neurological signs, signs of skull fracture in non-frontal areas and signs of basal skull fracture. The five-group classification of children allowed an excellent prediction in terms of likelihood of ICI (ROC area 0.972). ⋯ Selection of children with closed head trauma based on different combinations of signs and symptoms allows for early identification of subjects at different risk for ICI. In patients with minor head injuries, the absence of loss of consciousness, drowsiness, amnesia, prolonged headache, clinical evidence of basal or non-frontal skull fracture identified 100% of children without lesions. Validation of our results with a larger sample of patients with ICI would be highly desirable.

Multicenter Study Clinical Trial
The contribution of pulse oximetry to the early detection of congenital heart disease in newborns.
Approximately half of all newborns with congenital heart disease are asymptomatic in the first few days of life. Early detection of ductal-dependant cardiac malformations prior to ductal closure is, however, of significant clinical importance, as the treatment outcome is related to the time of diagnosis. Pulse oximetry has been proposed for early detection of congenital heart disease. The aims of the present study were: 1) to determine the effectiveness of a pulse-oximetric screening performed on the first day of life for the detection of congenital heart disease in otherwise healthy newborns and 2) to determine if a pulse-oximetric screening combined with clinical examination is superior in the diagnosis of congenital heart disease to clinical examination alone. This is a prospective, multi-centre study. Postductal pulse oximetry was performed between six and twelve hours of age in all newborns of greater than 35 weeks gestation. If pulse-oximetry-measured arterial oxygen saturation was less than 95%, echocardiography was performed. Pulse oximetry was performed in 3,262 newborns. Twenty-four infants (0.7%) had repeated saturations of less than 95%. Of these infants, 17 had congenital heart disease and five of the remaining seven had persistent pulmonary hypertension. No infant with a ductal-dependant or cyanotic congenital heart disease exhibited saturation values greater or equal to 95%. ⋯ postductal pulse-oximetric screening in the first few days of life is an effective means for detecting cyanotic congenital heart disease in otherwise healthy newborns.

The aim was to determine whether semi-quantitative procalcitonin (PCT-Q) measurements on admission can identify the severity of meningococcal infection in children. A total of 65 children (mean age 2.4 years) with meningococcal disease were included in a prospective study. All patients were treated with antibiotics, rehydration, inotropic drugs and mechanical ventilation if presenting with shock or respiratory failure. On admission, blood was drawn for routine laboratory analyses including absolute neutrophil count (NC), C-reactive protein (CRP) and PCT-Q (immunochromatographic test). A total of 33 patients presented with septic shock on admission of whom 18 developed multiple organ dysfunction syndrome (MODS) and 9 died. Forty-three patients showed a very high PCT-Q level (>or=10 ng/ml), 12 showed values between 2-9.9 ng/ml and the remaining 10 patients showed PCT-Q levels<2 ng/ml. All patients with a PCT-Q level<10 ng/ml survived, whereas all those who developed MODS or died had PCT-Q levels>or=10 ng/ml. Receiver operator curve analysis showed that PCT-Q and NC had a high predictive value for MODS and death. PCT-Q showed a sensitivity of 100%, a negative predictive value of 100% and a negative likelihood ratio of 0.0 for MODS and death. ⋯ semi-quantitative procalcitonin levels under 10 ng/ml predict good outcome of children with meningococcal infection. It is a highly sensitive method to identify patients with an increased risk of multiple organ dysfunction syndrome or death.

The aim of the study was to determine the characteristic features and outcome of carcinoid or mucoepidermoid tumours in children. A retrospective analysis of all patients treated for a carcinoid or mucoepidermoid tumour in France between 1984 and 2001 was performed. There were 11 cases of carcinoid tumour and 6 cases of mucoepidermoid tumour. The mean age of the patients was 10.5+/-3.0 years, with a range of 5 to 15 years. Twelve and 6 patients presented with evidence of bronchial obstruction and haemoptysis, respectively. Fibre optic bronchoscopy confirmed the presence of a bronchial tumour in all cases and endobronchial biopsies were diagnostic in 11 of 12 cases. A chest CT scan revealed the presence of a hypervascular tumour in 8 of 12 patients. The distribution of the location of the tumours was equal between the right and the left lung, and, in 9 cases, the airways were totally occluded by the tumour. Complete surgical resection (lobectomy in 15 patients and pneumonectomy in 2 patients) was performed in all cases without pre-operative chemotherapy or radiotherapy. The mean duration of follow-up was 4.0+/-3.0 years. In 2 patients, auscultation assymetry and an episode of haemoptysis revealed the recurrence of a mucoepidermoid tumour, successfully cured by removal of the tumour and chemotherapy and radiotherapy in one child. No death was observed. ⋯ Pulmonary carcinoid and mucoepidermoid tumours are rare in children. Bronchoscopic removal should not be performed. With aggressive surgical therapy, the prognosis is excellent. Fibre optic bronchoscopy confirms the presence of an endobronchial mass. A biopsy is needed for diagnosis and complete surgical removal is the treatment of choice. Long-term results are excellent but a clinical follow-up is recommended.
