Operative hysteroscopy intravascular absorption syndrome is an iatrogenic syndrome caused by absorption of hypo-osmolar distension medium during hysteroscopy, which can lead to rapid hyponatremia with resulting cerebral and pulmonary edema. We present a case of a 47-year-old female who underwent hysteroscopic myomectomy at an outpatient ambulatory surgical center who was brought to the emergency department with dyspnea, hypoxia, and altered mental status. Workup showed hyponatremia with cerebral edema on computed tomography of the head and pulmonary edema on chest radiograph. The patient improved after resuscitation with intravenous saline and supplemental oxygen, and she was discharged home the next day.

The zebrafish (Danio rerio) is becoming increasingly popular in the field of neurobehavioral research, including experimental, genetic, and pharmacological models of human brain disorders. While zebrafish research is rapidly expanding, its application as a translational neurobehavioral model is still in its relative infancy. Therefore, further investigation of new models is needed for targeting more domains and new, more complex brain disorders. The main aim of this paper is to discuss recent developments in the field of zebrafish neurobehavioral research, and to outline important emerging topics for further studies.
