The MEK inhibitor selumetinib reduces spinal neurofibroma burden in patients with NF1 and plexiform neurofibromas.

Background: Spinal neurofibromas (SNFs) in neurofibromatosis type 1 (NF1) can cause progressive spinal cord compression and neurological dysfunction. The MEK inhibitor selumetinib shrinks the majority of plexiform neurofibromas (PNs) in patients with NF1. We assessed the effect of selumetinib on SNF.

Targeting Refractory Sarcomas and Malignant Peripheral Nerve Sheath Tumors in a Phase I/II Study of Sirolimus in Combination with Ganetespib (SARC023).

Purpose: Malignant peripheral nerve sheath tumors (MPNSTs) are aggressive soft tissue sarcomas. Combining Hsp90 inhibitors to enhance endoplasmic reticulum stress with mTOR inhibition results in dramatic MPNST shrinkage in a genetically engineered MPNST mouse model. Ganetespib is an injectable potent small molecule inhibitor of Hsp90.

Myasthenia in pregnancy: best practice guidelines from a U.K. multispecialty working group.

A national U.K. workshop to discuss practical clinical management issues related to pregnancy in women with myasthenia gravis was held in May 2011.

Perioperative fasting in adults and children: guidelines from the European Society of Anaesthesiology.

This guideline aims to provide an overview of the present knowledge on aspects of perioperative fasting with assessment of the quality of the evidence. A systematic search was conducted in electronic databases to identify trials published between 1950 and late 2009 concerned with preoperative fasting, early resumption of oral intake and the effects of oral carbohydrate mixtures on gastric emptying and postoperative recovery. One study on preoperative fasting which had not been included in previous reviews and a further 13 studies published since the most recent review were identified.

Effect of food intake during labour on obstetric outcome: randomised controlled trial.

Objective: To investigate the effect of feeding during labour on obstetric and neonatal outcomes.

Design: Prospective randomised controlled trial.

Setting: Birth centre in London teaching hospital.

NPO during labor. Is there any scientific validation?

Maternal death from pulmonary aspiration of gastric contents has virtually disappeared in the United Kingdom. The one case documented in the most recent triennial report was a woman with multiorgan failure in intensive care and is probably not relevant to the current debate [1]. Although not so well documented, other Western countries seem to be experiencing the same decline in maternal death from this cause.

An evaluation of isotonic "sport drinks" during labor.

Unlabelled: We compared the metabolic effects of allowing women isotonic "sport drinks" rather than water to drink during labor. The effect of these drinks on gastric residual volume was also evaluated. Sixty women in early labor (cervical dilation <5 cm) were randomized to receive either isotonic sport drinks or water only.
