Pediatric interventional radiology workforce in North America: a descriptive analysis of demographics, educational backgrounds and scholarly activities.

BACKGROUND: Pediatric interventional radiology has grown as an advanced subspecialty with increased demand, number and complexity of cases, and number of pediatric institutions offering a pediatric interventional radiology service. Despite the overall increase in the number of pediatric interventionalists over the past two decades, there is a heterogeneity in their academic backgrounds and a lack of uniform training pathways. OBJECTIVE: To analyze the demographics, academic backgrounds and scholarly activities of pediatric interventionalists across the United States (U.S.) and Canada. MATERIALS AND METHODS: A list of all members of the Society for Pediatric Interventional Radiology was obtained and pediatric interventionalists at academic and private practice institutions in the U.S. and Canada were included. Publicly available online sources were used to gather demographic and educational information about each pediatric interventionalist, which included the online curriculum vitae, the HealthGrades.com and Doximity.com websites, and Elsevier's Scopus database. Demographic and educational data including age, gender, educational background, additional degrees, academic rank, previous leadership positions, and metrics of scholarly activities were recorded. Fellowships in diagnostic pediatric radiology, adult interventional radiology and/or pediatric interventional radiology were recorded. Mann-Whitney U tests and Kruskal-Wallis tests were used to compare differences between groups. RESULTS: One hundred and twenty-five pediatric interventionalists were included, of whom 24 (19.2%) were female. The mean age was 48.6 years (standard deviation [SD]: 10.6, median: 45 years, range: 36-82 years). There was no statistical difference between median age for male versus female pediatric interventionalists (44.5 years vs. 45 years, P=0.89). A majority of pediatric interventionalists were American medical school graduates (96, 76.8%), while 29 (23.2%) were international medical graduates. Eighty-three percent (104) of the pediatric interventionalists completed diagnostic radiology residency training in the U.S., most commonly at the University of Cincinnati in Ohio (6.4%) and Washington University in St. Louis, MO (5.6%). Among fellowship training, pediatric interventionalists completed a pediatric radiology fellowship (61.6%), adult interventional radiology fellowship (40%) and/or a dedicated pediatric interventional radiology fellowship (57.6%). The mean±SD (median) publications, citations and Hirsch index (h-index) for pediatric interventionalists were 32±45 (12), 68±1,317 (120) and 9±10 (5), respectively. There was a statistically higher number of publications, citations and h-index with increasing academic rank at the assistant, associate and professor levels (P<0.001 for all groups). International medical graduate pediatric interventionalists had a higher, but not statistically significant, median publication count (26 vs. 11, P=0.0.25), citation count (236 vs. 93, P=0.36) and h-index (9.0 vs. 5, P=0.24) compared to pediatric interventional radiologists from American medical schools. CONCLUSION: Pediatric interventionalists in North America are predominantly male, with about a quarter having graduated from international medical schools. Pediatric radiology fellowship, followed by pediatric interventional radiology fellowship, was the most frequently pursued training pathway.

Williams-Campbell syndrome: an unusual presentation in an adult patient.

OBJECTIVE: Williams-Campbell syndrome (WCS) is a rare congenital disorder, which leads to bronchiectasis affecting fourth to sixth order of bronchial divisions. Symptoms include cough, sputum, wheeze and recurrent pulmonary infections, classically seen in the paediatric age group with selective bronchiectasis of the mid-order bronchioles. The literature describing diagnosis of Williams-Campbell syndrome in adult population is very sparse. METHODS: This report presents a 62-year-old female with cough, fever, dyspnea and generalized body ache. She has had multiple admissions to the hospital since her childhood due to recurrent lower respiratory tract infections. Imaging findings demonstrated multiple cystic thin walled airways, compatible with bronchiectatic changes in the upper, middle and lower lobes bilaterally, bronchial wall thickening with air-fluid levels prominent in the fifth and sixth generation bronchial divisions, with normal calibre trachea and central bronchi. These radiological findings are consistent with diagnosis of Williams-Campbell syndrome, which was diagnosed after ruling out the other common causes of bronchiectasis. CONCLUSION: Williams-Campbell syndrome is a rare congenital cystic lung disease, the diagnosis of which is made by exclusion of common causes of bronchiectasis such as cystic fibrosis, allergic bronchopulmonary aspergillosis, tuberculosis, dyskinetic cilia syndrome and alpha-1 antitrypsin deficiency. Whenever the clinical picture is consistent with bronchiectasis, especially involving the mid-order bronchioles and recurrent pulmonary infections, it is wise to include WCS in the list of differential diagnoses, even in the adult population.

Epidemiology of male breast diseases: A 10-year institutional review.

OBJECTIVE: To review breast imaging utilization and epidemiology of breast diseases in male patients referred to our breast center. MATERIAL AND METHODS: A retrospective analysis of all male patients who underwent breast imaging at our institution over a 10 year period (03/14/2008 to 03/13/2018) was performed. Patient history, imaging findings, biopsy reports, surgical interventions and follow-up data were reviewed. RESULTS: Over the 10 year period, 143 male patients (0.1% of referred breast center patients) underwent breast imaging (versus 139,134 female patients). Mean age was 57.4 years (SD 19.7, median 59, range 21-92 years). The most common indication for referral was a palpable breast mass (98%). The most common diagnosis was gynecomastia (72%). Of the 20 (14%) patients who underwent core biopsy; 1 (0.7%) had breast cancer and the remaining 19 had benign pathologies. Follow-up imaging was recommended for 22 (15.4%) patients, of whom 15 (68%) were lost to follow-up. Two patients under the age of 25 years inadvertently underwent initial mammography instead of ultrasound. CONCLUSION: The epidemiology of breast diseases in our male patient population mirrors that of the general male population worldwide; with an overwhelming 99.3% cases falling into benign category. Two-thirds of our male patients for whom short interval follow up was recommended were lost to follow-up, signifying the need for a more proactive approach in ensuring their compliance. It is important to increase awareness among referring clinicians and general radiologists regarding male breast imaging recommendations so that the appropriate imaging study is performed.

Analysis of Demographic and Educational Backgrounds of Interventional Neuroradiology Fellowship Program Director Workforce in North America.

PURPOSE: To analyse the demographics, academic background, and scholarly activity of Interventional Neuroradiology (INR)/Endovascular Surgical Neuroradiology (ESN) program directors (PDs) in the United States (US) and Canada. METHODS: A list of all INR/ESN fellowships was obtained from the Accreditation Council for Graduate Medical Education, the Committee on Advanced Subspecialty Training, maintained by Society of Neurological Surgeons, the NeuroInterventional Training list website maintained by the Society of NeuroInterventional Surgery, and the Neurosurgical Fellowship Training Program Directory website maintained by the American Association of Neurological Surgeons. Online search was performed to identify PDs for these programs. Publicly available sources used to gather information about each PD included the program websites, the HealthGrades and Doximity websites, and Elsevier's Scopus database. Demographic and educational data including age, gender, educational background, subspecialty, appointment age, interval between residency completion and appointment as PD, additional degrees, academic rank, prior leadership positions, and metrics of scholarly activity were recorded. One-way analysis of variance was used to determine differences between the means of different groups. RESULTS: A total of 78 PDs from 72 programs were included, of which 72 (92.3%) were male with the mean age of 49.59 years (SD 7.25). Specialty division of PDs was neurosurgery (40, 51.3%), radiology (26, 33.3%), and neurology (10, 12.8%), whereas 2 PDs were dual board-certified in neurology and radiology. Twenty-five (32.1%) PDs attended an international medical school. All PDs received an MD degree or foreign equivalent, with no PD holding a DO degree. Eleven PDs received a PhD degree and 16 PDs received fellowship from a professional medical society. The mean ± SD publications, citations, and h-indexes of PDs were 111.32 ± 121.18, 2985.0 ± 1459.0 and 22.27 ± 15.45, respectively. There was no statistical difference in scholarly activity among PDs when stratified on the basis of specialty, gender, and US region. CONCLUSION: INR/ESN PDs are predominantly male, with a majority from neurosurgery background, and thirty percent having graduated from international medical schools.
