Article Synopsis
- Ectopic pregnancy is a major cause of maternal mortality during the first trimester, with the fallopian tube being the most common site of occurrence.
- Surgical options include salpingotomy (partial removal of the affected tube) and salpingectomy (complete removal), with persistent ectopic pregnancies more likely after salpingotomy.
- In the presented case, a patient underwent a right salpingectomy but returned with abdominal pain and high beta-HCG levels; a second surgery revealed ectopic tissue that was subsequently treated successfully with a single dose of methotrexate.
The archaeological record documenting human history in deserts is commonly concentrated along rivers in terraces or other landforms built by river sediment deposits. Today that record is at risk in many river valleys owing to human resource and infrastructure development activities, including the construction and operation of dams. We assessed the effects of the operations of Glen Canyon Dam - which, since its closure in 1963, has imposed drastic changes to flow, sediment supply and distribution, and riparian vegetation - on a population of 362 archaeological sites in the Colorado River corridor through Grand Canyon National Park, Arizona, USA.
