Patients with suspected VAP, in whom no bacterial pathogen was identified and in whom Candida species were isolated from RT cultures, exhibited a greater burden of illness compared with similar patients without Candida. Whether Candida species colonization of RT secretions is a marker of disease severity or actually contributes to poorer clinical outcomes remains unclear.

We have identified modifiable risk factors for delirium. Future studies should aim at implementing strategies to modify these risk factors and evaluate their impact on the risk of delirium.

A potential interaction exists between VPA and all ritonavir-boosted antiretroviral regimens. Clinicians should monitor patients closely for a decreased VPA effect when these medications are given concomitantly.

We report the case of a 9-year-old girl with multiple problems due to hypothalamic dysfunction of obscure origin: apnoeic spells, behavioural problems, developmental delay, hypodipsia with bouts of hypernatraemia, episodes of spontaneous hypothermia, obesity, petit-mal seizures, non-progressive precocious puberty, absence of respiratory response to CO2 and probably insensitivity of hyposensitivity to pain. She also had hyperprolactinaemia and decreased human growth hormone secretion. Hypothyroidism of central origin and hyposecretion of cortisol were also present. Multiple brain CT-scans failed to reveal any tumour or other anatomical abnormality. Her clinical course was improved initially by treatment with clomipramine, but she died suddenly, and the autopsy failed to disclose any anatomical lesion. We compare this case with three similar previously reported cases.
