Acetaminophen overdose is common and can result from deliberate/nonstaggered or accidental/staggered ingestion. Patients presenting within 24 h of an acetaminophen overdose can safely be managed on medical wards. ⋯ Acetaminophen-induced acute liver failure (ALF) requires meticulous supportive care in an intensive care unit (ICU), with early identification and transfer of patients who are likely to require liver transplantation to a specialist liver centre. The modified King's College Hospital criteria (incorporating lactate into the traditional criteria) represent the best tool for identifying patients who require transplantation.

The Toll-like receptors (TLRs) are essential transmembrane signaling receptors of the innate immune system that alert the host to the presence of a microbial invader. The recent discovery of the TLRs has rapidly expanded our knowledge of molecular events that initiate host-pathogen interactions. ⋯ The fundamental significance of the TLRs in the generation of systemic inflammation and the pathogenesis of septic shock is reviewed. The potential clinical implications of therapeutic modulation of these recently characterized receptors of innate immunity are also discussed.

Severe sepsis continues to lead to critical illness. Few therapeutic options exist other than antibiotic therapy and general supportive care. ⋯ This commentary will discuss the therapeutic targets revealed by our new understanding of the Toll-like receptor. The potential clinical difficulties that may result from intervention at this pattern-recognition receptor will also be explored.

Randomized Controlled Trial Clinical Trial
Tidal breathing flow-volume loops in bronchiolitis in infancy: the effect of albuterol [ISRCTN47364493].
To evaluate the effect of nebulized albuterol on tidal breathing flow-volume loops in infants with bronchiolitis due to respiratory syncytial virus. ⋯ Nebulized albuterol in infants with mild bronchiolitis due to respiratory syncytial virus did not improve VPTEF/VE and tPTEF/tE but did decrease TEF10 and 25/PT.

Review
Pro/con clinical debate: are steroids useful in the management of patients with septic shock?
Decision-making in the intensive care unit is often very difficult. Although we are encouraged to make evidence-based decisions, this may be difficult for a number of reasons. To begin with, evidence may not exist to answer the clinical question. ⋯ Finally, emotions are often highly charged when caring for patients that have a significant chance of death, and care-givers as well as families are frequently prepared to take chances on a therapy whose benefit is not entirely clear. Steroid use in septic shock is an example of a therapy that makes some sense but has conflicting support in the literature. In this issue of Critical Care Forum, the two sides of this often heated debate are brought to the forefront in an interesting format.
