RESUMO
BACKGROUND AND PURPOSE: Many studies have explored the possibility of using cranial ultrasound for discerning intracranial pathologies like tumors, hemorrhagic stroke, or subdural hemorrhage in clinical scenarios where computer tomography may not be accessible or feasible. The visualization of intracranial anatomy on B-mode ultrasound is challenging due to the presence of the skull that limits insonation to a few segments on the temporal bone that are thin enough to allow transcranial transmission of sound. Several artifacts are produced by hyperechoic signals inherent in brain and skull anatomy when images are created using temporal windows. METHODS: While the literature has investigated the accuracy of diagnosis of intracranial pathology with ultrasound, we lack a reference source for images acquired on cranial topography on B-mode ultrasound to illustrate the appearance of normal and abnormal structures of the brain and skull. Two investigators underwent hands-on training in Cranial point-of-care ultrasound (c-POCUS) and acquired multiple images from each patient to obtain the most in-depth images of brain to investigate all visible anatomical structures and pathology within 24 hours of any CT/MRI imaging done. RESULTS: Most reproducible structures visible on c-POCUS included bony parts and parenchymal structures. Transcranial and abdominal presets were equivalent in elucidating anatomical structures. Brain pathology like parenchymal hemorrhage, cerebral edema, and hydrocephalus were also visualized. CONCLUSIONS: We present an illustrated anatomical atlas of cranial ultrasound B-mode images acquired in various pathologies in a critical care environment and compare our findings with published literature by performing a scoping review of literature on the subject.

Introduction: Urogynecologic disorders are highly prevalent, and many physicians across various specialties will encounter and care for patients with pelvic floor disorders. Yet most medical students have had limited to no experience in diagnosing and managing pelvic floor disorders, resulting in a gap in clinical education. Methods: Three virtual and interactive urogynecologic patient cases were developed on an e-learning platform with an overall goal of increasing clinical exposure to various pelvic floor disorders. The cases were integrated into the medical student obstetrics and gynecology clerkship during the 2020-2021 academic year (n = 40). Participants provided feedback regarding usability, acceptability, and educational value of the cases. Results: Twenty-one students (52%) completed the survey. Ninety percent (n = 19) agreed or strongly agreed that they were satisfied with the cases, and 71% (n = 15) agreed or strongly agreed that they would recommend the virtual patient cases to other students. All students (n = 21) felt that the format was easy to use and reported that the cases were appropriate for their level of learning. Most students felt that the cases increased or significantly increased their confidence regarding nonsurgical and surgical management options for pelvic floor disorders. Discussion: Our findings suggest that these interactive virtual patient cases are an acceptable, valuable, and effective tool for learners. Utilizing the cases can help mitigate existing disparities in exposure to pelvic floor disorders both highlighted by and preceding the COVID-19 pandemic.

Neurogenic thoracic outlet syndrome (NTOS) is a disorder that is often misdiagnosed and challenging to treat due to the varied and complex mechanisms that precipitate common sensory symptoms associated with neurovascular dysfunction. In this report, we describe a 21-year-old male who presented with left NTOS after being involved in a motor vehicle collision the previous year. Although NTOS is a condition known to develop after motor vehicle collisions, the mechanism of NTOS in this case, the deploying airbag, has not been documented in existing literature. The patient was first treated conservatively with physical therapy, but treatment failed to relieve his symptoms. A left first rib resection using the transaxillary approach and an anterior scalenectomy was performed without any complications, and the patient's symptoms had improved 3 months postoperation.
