Considering the potential immunomodulatory role of melatonin and its direct antioxidant activity, disturbances of the melatonin secretion pattern in the septic conditions could be particularly unfavorable. The aim of this study was to evaluate the nocturnal melatonin concentration and total 24-hr excretion of 6-sulfatoxymelatoninsulfate, melatonin's major urinary metabolite, in children with sepsis in the pediatric intensive care unit. ⋯ The present study shows that, in contradiction to results in adult patients, the nocturnal melatonin concentrations are not decreased in septic pediatric intensive care unit patients despite severe disease. Further investigations are needed to identify whether treatment with melatonin may have beneficial effects in pediatric intensive care unit patients with sepsis/septic shock.

Risk factors associated with increased length of mechanical ventilation in children.
Invasive mechanical ventilation, if prolonged, may lead to high morbidity and mortality. ⋯ Among the risk factors identified, the use of noninvasive ventilation and continuous intravenous sedation on the first day of ventilation are the only two interventions that were associated with prolonged acute invasive mechanical ventilation. Further research is needed to study the impact of sedation protocols on the duration of mechanical ventilation in children.

Intubation is a risk factor for nosocomial sinusitis in adult intensive care patients. Sinusitis in intubated adults can be an occult cause of fever. In children, nasal intubation may increase the risk of sinusitis. No pediatric study has determined the frequency of nosocomial sinusitis in the pediatric intensive care unit setting. We hypothesized that within a subset of patients who had head computed tomography imaging 1) the incidental frequency of sinusitis in pediatric intensive care unit patients exceeds the frequency in non-pediatric intensive care unit patients, 2) the frequency of sinusitis is greater in pediatric intensive care unit patients with a tube (nasotracheal, nasogastric, orotracheal, or orogastric) compared to those without a tube, and 3) nasal tubes confer an increased risk for sinusitis over oral tubes. ⋯ A total of 44.3% of our pediatric intensive care unit patients imaged for reasons other than evaluation for sinus disease had evidence of sinusitis, and 51.3% of these had fever. These findings raise the concern that sinusitis in pediatric intensive care unit patients is common and should be considered in the differential diagnosis of fever in pediatric intensive care unit patients.

Case ReportsThe critically ill patient with ataxia-telangiectasia: a case series.
To describe the presentation, clinical course, and outcomes of critically ill patients with ataxia-telangiectasia. ⋯ Critically ill patients with ataxia-telangiectasia have complex, multisystem diseases. In this case series, the most common intensive care unit admission diagnosis was respiratory failure. Suspected or confirmed bacterial infections were prevalent. Neuropathologic autopsy findings were similar to those previously reported. Special considerations for the critical care of patients with ataxia-telangiectasia are discussed.

Association between high cytokine levels with white matter injury in preterm infants with sepsis.
To examine the association among interleukin-6, interleukin-8, tumor necrosis factor-α, interleukin-10, and interleukin-1β and white matter injury in very-low-birth-weight infants with clinical sepsis and to help predict infants at risk for development of white matter injury. ⋯ Very-low-birth-weight infants with proven early-onset sepsis, necrotizing enterocolitis, and high plasma levels of interleukin-6, interleukin-8, and tumor necrosis factor-α are at high risk for white matter injury.
