Pediatric Neuroradiology Pre-Call Primer, Trevor Morrison, Gilbert Vezina, Nadja Kadom

E-Learning Modules

Pediatric neuroimaging can provide a challenge to radiology residents during call due to the fact that it is infrequently encountered in many institutions. The goal of this teaching tool is to provide radiology residents with background knowledge in pediatric brain anatomy and pathology in preparation for taking call. There is one teaching tool and one assessment tool with answers, all three of which are in PowerPoint format. Emergency neuroradiology topics discussed in this module are sutures, skull fractures, bleeds, sulci and mass effect, cisterns, and herniations. After implementing this teaching tool at our institution with all incoming residents and fellows, …

A Single Baseline Ultrasound Assessment Of Fibroid Presence And Size Is Strongly Predictive Of Future Uterine Procedure: 8-Year Follow-Up Of Randomly Sampled Premenopausal Women Aged 35-49 Years., Donna D. Baird, T M Saldana, D L Shore, Michael C. Hill, J M Schectman

Radiology Faculty Publications

STUDY QUESTION: How well can a single baseline ultrasound assessment of fibroid burden (presence or absence of fibroids and size of largest, if present) predict future probability of having a major uterine procedure?

SUMMARY ANSWER: During an 8-year follow-up period, the risk of having a major uterine procedure was 2% for those without fibroids and increased with fibroid size for those with fibroids, reaching 47% for those with fibroids ≥4 cm in diameter at baseline.

WHAT IS KNOWN ALREADY: Uterine fibroids are a leading indication for hysterectomy. However, when fibroids are found, there are few available data to help clinicians …

Re-Expansion Pulmonary Edema, Talal Alzahrani, Nawaf Abaalkhail, Mayssam Nehme, Jalil Ahari

Re-expansion pulmonary edema (RPE) is a rare complication of therapeutic thoracentesis. Unfortunately, there is no definitive treatment modality for RPE. The high mortality rate, reported up to 21%, presses the issue for finding adequate prevention and treatment. Here we report a new management modality that is very useful for a patient with RPE.

Case Report: An 80-year-old man with a history of hypertension, atrial fibrillation, congestive heart failure with preserved ejection fraction, and sacral decubitus ulcer, who was admitted for surgical debridement of his ulcer. He developed hospital-acquired pneumonia and was resolved with antibiotics and aggressive hydration. He became hypoxic, …

Functional Properties Of Resting State Networks In Healthy Full-Term Newborns., Josepheen De Asis-Cruz, Marine Bouyssi-Kobar, Iordanis Evangelou, Gilbert Vezina, Catherine Limperopoulos

Radiology Faculty Publications

Objective, early, and non-invasive assessment of brain function in high-risk newborns is critical to initiate timely interventions and to minimize long-term neurodevelopmental disabilities. A prerequisite to identifying deviations from normal, however, is the availability of baseline measures of brain function derived from healthy, full-term newborns. Recent advances in functional MRI combined with graph theoretic techniques may provide important, currently unavailable, quantitative markers of normal neurodevelopment. In the current study, we describe important properties of resting state networks in 60 healthy, full-term, unsedated newborns. The neonate brain exhibited an efficient and economical small world topology: densely connected nearby regions, sparse, but …
