Retrocaval ureter is a rare, congenital anomaly of the inferior vena cava. Due to an abnormal process in embryogenesis, the ureter descends posterior to the inferior vena cava. Although the anomaly can be found in pediatric patients, it most commonly manifests symptoms between the third and fourth decade of life that are typically due to ureteric obstruction, such as hydronephrosis.

Further, the understanding of feedback has changed from information about a performance directed to the learner performing the task, to a dialogue, which enables the learner to act and develop.In health professional education, feedback is a complex interaction between trainee, supervisor and the healthcare system.

This article is an overview of the principles of exodontia including the physics principles underlying the appropriate use of dental elevators and forceps. Failure to understand the instrumentation and the physics principles being used can cause prolonged operative time, iatrogenic injury to the patient, and unnecessary fatigue and/or injury to the provider.

Clear processes of validity and reliability are needed in the development of simulated scenarios for the purpose of replication and the transfer of findings to other contexts.
Methods: This paper reports a methodological review of CINAHL to determine how valid and reliable simulated patient scenarios are developed.
The 2012 submarine eruption of Havre volcano in the Kermadec arc, New Zealand, is the largest deep-ocean eruption in history and one of very few recorded submarine eruptions involving rhyolite magma. It was recognized from a gigantic 400-km pumice raft seen in satellite imagery, but the complexity of this event was concealed beneath the sea surface. Mapping, observations, and sampling by submersibles have provided an exceptionally high fidelity record of the seafloor products, which included lava sourced from 14 vents at water depths of 900 to 1220 m, and fragmental deposits including giant pumice clasts up to 9 m in diameter.
