The main indication from the analysis of these data is that NSAIDs could be given in patients receiving opioids, evaluating their benefit and weight on opioid therapy in individual patients who have a favorable response to justify a prolonged use.

“Percutaneous endoscopic gastrostomy (PEG) is widely performed. However, despite its widespread use, complications often follow and some of them are life-threatening. We report on two patients who developed pseudoaneurysm

after PEG and how the bleeding was stemmed by transcatheter arterial embolization. Case 1 is an 84-year-old man. PEG by the pull method using Mdm2 inhibitor One Step Button 24 Fr was performed. Blood-laced vomiting, followed by hemorrhagic shock was observed on day 21. Pseudoaneurysm less than 10 mm in diameter was observed in the gastroepiploic artery by urgent percutaneous abdominal angiography. A microcatheter was advanced selectively and the affected area was embolized by metallic coils and n-butyl cyanoacrylate. Case 2 is an 89-year-old man. PEG by the pull method using One Step Button 24 Fr was performed. On day 28, bleeding from the gastrostomy portion occurred and the patient went into shock. On urgent percutaneous

abdominal angiography, pseudoaneurysm approximate to 5 mm in diameter was detected in the left gastric artery. A microcatheter click here was advanced selectively and the affected area was embolized by metallic coils and n-butyl cyanoacrylate. In the present two cases, gastrostomies were created in the anterior wall of the mid body portion as suitable for PEG position, but the bleedings occurred because of pseudoaneurysm formation accompanied by damage QNZ to the gastroepiploic or the left gastric artery. Those who perform PEG on a regular basis should be aware of the possibility of pseudoaneurysm as a serious adverse event. (C) 2013 Wolters

“The global climate is changing rapidly and Arctic regions are showing responses to recent warming. Responses of tundra ecosystems to climate change have been examined primarily through short-term experimental manipulations, with few studies of long-term ambient change. We investigated changes in above- and belowground biomass of wet sedge tundra to the warming climate of the Canadian High Arctic over the past 25 years. Aboveground standing crop was harvested from five sedge meadow sites and belowground biomass was sampled from one of the sites in the early 1980s and in 2005 using the same methods. Aboveground biomass was on average 158% greater in 2005 than in the early 1980s. The belowground biomass was also much greater in 2005: root biomass increased by 67% and rhizome biomass by 139% since the early 1980s. Dominant species from each functional group (graminoids, shrubs and forbs) showed significant increases in aboveground biomass.
