Dieulafoy’s lesions are rare vascular malformations of the gastrointestinal tract. A Dieulafoy’s lesion is an aberrant vessel that does not reduce in caliber when it extends from the submucosa to the mucosa. Damage to this artery can cause severe and intermittent arterial bleeding from small vascular stumps that are difficult to visualize. Furthermore, these catastrophic bleeding episodes frequently result in hemodynamic instability and the need for transfusion of multiple blood products. Recently, uremic syndrome has been identified as a risk factor for gastric mucosal lesions. We present two clinical cases of acute digestive bleeding due to Dielafoy lesion with chronic kidney disease as the main cause, where two different therapies were performed endoscopically. We concluded with the results of our patients that the best therapy was the application of the hemostatic hemoclip on the injury vs the injection with adrenaline on the wound site. Uremia is identified as a risk factor for upper gastrointestinal bleeding in patients with pre-existing Dieulafoy’s lesion, as well as a higher incidence of new bleeding.

The use of dendrochronology to study and date geomorphic processes in volcanic environments is still incipient, even more so on the volcanic slopes covered by temperate forests in central Mexico. Mass movements, such as debris flows, often impact forest stands where they cause damage to individual trees, thereby generating growth disturbances(GD) in the tree-ring records. The identification and dating of GD enables reconstruction of the age of trees colonizing bare surfaces after major events, but also allows the assessment of the frequency or spatial distribution of past geomorphic process activity. Here we used increment cores from 65 Pinus leiophylla, Abies religiosa, and Alnus jorullensis trees growing in the Axal gorge, on the southern slopes of La Malinche volcano, to unravel past debris-flow activity both temporally and spatially. Based on the combination of GD records, a weighted tree response index(Wit), field evidence and hydrometeorological records, we reconstructed 23 debris flows since ***, almost two-thirds of the reconstructed years with debris-flow activity in Axal gorge match with events recorded in Axaltzintle gorge located on the NE slopes of La Malinche. These findings suggest a regional triggering mechanism, most likely related to the occurrence of hurricanes. This research could be useful for disaster risk management of the La Malinche National Park.

青藏高原及其周边区域通常被称为地球“第三极”.它不仅是受全球气候变暖影响最显著的区域之一,同时也是全球冰湖溃决洪水(Glacial Lake Outburst Floods,GLOFs)灾害频发的地区之一.尽管之前已经有很多发生在第三极地区的GLOF事件被报道,但考虑到GLOFs通常发生在高海拔无人区以及一些小规模的GLOFs并没有对下游地区造成太大的破坏,可能仍然有一些已经发生的GLOF事件并没有被发现和报道.基于此假设,本文借助大量高分辨率的卫星影像和3个GLOF发生后遗留的典型地貌形态特征对整个第三极地区6万多个冰湖进行了全面和系统地检查,最终识别出176个之前没有被记录的GLOF源头,其中167个来自冰碛坝湖,9个来自基岩坝湖.这一数量是所有已报道GLOF源头数量(75个)的2倍多.综合这些新发现的和已报道的GLOF案例,本文总结出第三极地区GLOF高发的4个热点地区为:喜马拉雅、冈底斯山、念青唐古拉山和天山地区.这些新识别的GLOF案例将为未来的研究提供重要的基础,从而有助于更好地认识和理解第三极地区GLOF的发生机理及真实的发生频率.
