We undertook systematic reviews to examine key questions (KQs) related to pediatric chronic wet cough. In children with chronic (>4-weeks) wet/productive cough not related to bronchiectasis; (KQ1)-how effective are antibiotics in improving the resolution of cough? If so, what and for how long? and; (KQ2)-when should they be referred for further investigations? ⋯ There is high quality evidence that in children aged ≤14-years with chronic (>4-weeks duration) wet or productive cough, the use of appropriate antibiotics improves cough resolution. There is also high quality evidence that when specific cough pointers (e.g. digital clubbing) are present in children with wet cough, further investigations (e.g. flexible bronchoscopy, chest CTs and immunity tests) should be undertaken. When the wet cough does not improve by 4-weeks of antibiotics, there is moderate quality evidence that children should be referred to a major center for consideration of further investigations to determine whether an underlying lung or other disease are present.

Critical care transesophageal echocardiography (TEE) is useful in characterizing shock states encountered by intensivists when transthoracic echocardiography (TTE) gives insufficient information or when more detailed analysis of cardiac structures is needed. It is safe, feasible, and easy to learn and is a recommended component of advanced critical care echocardiography. ⋯ It should be considered a companion article to a recent two-part series in CHEST that focused on advanced critical care TTE. Included with this article is an online supplement that has a representative series of critical care TEE images with clinical commentary.

The Chiari 1 malformation is characterized by > 5-mm herniation of the cerebellar tonsils through the foramen magnum. Consequent compression of the brain stem and nearby neuronal structures involved in respiratory control and maintenance of pharyngeal wall muscle tone may result in respiratory changes during sleep. ⋯ Although data have accrued on the significance of sleep-related breathing disorders in patients with the Chiari 1 malformation, many management questions remain unanswered. This article reviews the available literature on prevalence and management of sleep-related breathing disorders in patients with the Chiari 1 malformation.

Randomized Controlled Trial Multicenter Study
Delirium and circadian rhythm of melatonin during weaning from mechanical ventilation: An ancillary study of a weaning trial.
Delirium is frequent in patients in the ICU, but its association with the outcome of weaning from mechanical ventilation has not been assessed. Circadian rhythm alteration may favor delirium. In the current study, we assessed the impact of delirium during weaning and associated alterations in the circadian rhythm of melatonin excretion. ⋯ Delirium is frequent at the initiation of ventilator weaning. It is associated with a prolongation of weaning and an alteration in the circadian rhythm of melatonin excretion.

The first of this two-part series on critical illness in pregnancy dealt with obstetric disorders. In Part II, medical conditions that commonly affect pregnant women or worsen during pregnancy are discussed. ARDS occurs more frequently in pregnancy. ⋯ Other common conditions discussed are aspiration of gastric contents, OSA, thyroid disorders, diabetic ketoacidosis, and cardiopulmonary arrest in pregnancy. Studies confined to pregnant women are available for only a few of these conditions. We have, therefore, reviewed pregnancy-specific adjustments in the management of these disorders.
