ReviewContinuous negative extrathoracic pressure or continuous positive airway pressure for acute hypoxemic respiratory failure in children.
Acute hypoxemic respiratory failure (AHRF) is an important cause of mortality and morbidity in the pediatric age group. Positive pressure ventilation is currently the standard of care, though is known to be associated with complications. Continuous negative extrathoracic pressure ventilation (CNEP) or continuous positive airway pressure ventilation delivered via non-invasive approaches (Ni-CPAP) have shown certain beneficial effects in animal and uncontrolled human studies. ⋯ There is a lack of well designed, controlled experiments of noninvasive modes of respiratory support in children with AHRF. Implication for research: Reduction of in-hospital mortality is an important outcome and even a small reduction could be beneficial. Studies assessing other outcomes such as avoidance of intubation and its associated complications, reduction in hospital stay and improvement in patient comfort are also valuable in gauging the overall impact of these strategies.

ReviewNon-steroidal anti-inflammatory drugs for pain in women with endometriosis.
Endometriosis is a common gynaecological condition that affects women and can lead to painful symptoms and infertility. It affects women's quality of life greatly, impacting on their careers, everyday activities, sexual and non-sexual relationships, and fertility. Non-steroidal anti-inflammatory drugs (NSAIDs) are the most commonly used first-line treatment for endometriosis. ⋯ There is inconclusive evidence to show whether NSAIDs (naproxen) are effective in managing pain caused by endometriosis. There is no evidence to show whether any individual NSAID is more effective than another. As shown in other Cochrane reviews, women using NSAIDs need to be aware of the possibility that these drugs may cause unintended effects.

Editor's note: The anti-inflammatory drug rofecoxib (Vioxx) was withdrawn from the market at the end of September 2004 after it was shown that long-term use (greater than 18 months) could increase the risk of heart attack and stroke. So far, other similar anti-inflammatory drugs are unaffected. Further information is available at www.vioxx.com. Rofecoxib is a selective cyclooxygenase-2 (COX-2) inhibitor that was licensed in the UK and the US for acute pain treatment and is associated with fewer gastrointestinal adverse events than conventional NSAIDs. Rofecoxib is believed to be at least as effective as conventional non-steroidal anti-inflammatory drugs (NSAIDs) for postoperative pain. ⋯ Rofecoxib 50 mg (a dose 2 to 4 times the standard daily dose for chronic pain) is an effective single dose oral analgesic for acute postoperative pain.

Acute ureteric colic is a common cause of severe and debilitating pain. Theoretically, increasing fluid flow through the affected kidney might expedite stone passage, thereby improving symptoms more quickly. Unfortunately, for interventions such as high volume intravenous or oral fluids and diuretics that are aimed at doing this, the efficacy and safety is uncertain. ⋯ Unfortunately, we could find no credible evidence in the literature regarding either of these two treatment modalities. Given their potential positive impact, the role of diuretics and high volume fluid therapy in acute ureteric colic should be examined to determine their safety and efficacy in facilitating stone passage.

ReviewLaryngeal mask airway versus bag-mask ventilation or endotracheal intubation for neonatal resuscitation.
Providing effective positive pressure ventilation is the single most important component of successful neonatal resuscitation. Ventilation is frequently initiated with a manual resuscitation bag and face-mask (BMV) followed by endotracheal intubation (ETT) if depression continues. These techniques may be difficult to perform successfully resulting in prolonged resuscitation or severe neonatal depression. The laryngeal mask airway (LMA) may achieve initial ventilation and successful resuscitation faster than a bag-mask device or endotracheal intubation. ⋯ The LMA can achieve effective ventilation during neonatal resuscitation in a time-frame consistent with current guidelines. There is no evidence to evaluate the relative efficacy and safety of the LMA compared with BMV as the primary airway device. A single, small randomised controlled trial found no clinically significant difference between the LMA and ETT when BMV was unsuccessful. Case series and case reports suggest that the LMA can provide an effective rescue airway during resuscitation if both BMV and ETT have been unsuccessful. A well-designed randomised controlled trial comparing the LMA with BMV during neonatal resuscitation is warranted.
