Unusual pediatric lung infections: imaging findings.

Pediatric lung infections continue to be a leading cause of pediatric morbidity and mortality. Although both pediatric and general radiologists are familiar with typical lung infections and their imaging findings in children, relatively rare lung infections continue to present a diagnostic challenge. In addition, the advances in radiological imaging and emergence of several new lung infections in recent years facilitated the need for up-to-date knowledge on this topic. In this review article, we discuss the imaging findings of pediatric lung infections caused by unusual/uncommon and new pathogens. We review the epidemiological, clinical, and radiological imaging findings of viral (coronavirus disease 2019, Middle East respiratory syndrome, bird flu), bacterial (Streptococcus anginosus, Francisella tularensis, Chlamydia psittaci), and parasitic lung infections (echinococcosis, paragonimiasis, amoebiasis). Additional disorders whose clinical course and imaging findings may mimic lung infections in children (hypersensitivity pneumonitis, pulmonary hemorrhage, eosinophilic pneumonia) are also presented, to aid in differential diagnosis. As the clinical presentation of children with new and unusual lung infections is often non-specific, imaging evaluation plays an important role in initial detection, follow-up for disease progression, and assessment of potential complications.

Global resources in the fight against tuberculosis.

Tuberculosis continues to be a significant cause of mortality and morbidity worldwide, particularly in developing countries. Diagnosis and treatment of paediatric patients presents a challenge that can only be improved by the joint efforts of the international community, working together in cooperation and partnership. This article reviews global resources available to doctors and healthcare professionals in the fight against TB, including international programmes, policies and healthcare pathways. Special attention is paid to the role of international paediatric radiology in improving diagnostics, including available educational resources and support on a global, regional, national and individual level.

Tuberculosis revisted: classic imaging findings in childhood.

Tuberculosis (TB) remains one of the major public health threats worldwide, despite improved diagnostic and therapeutic methods. Tuberculosis is one of the main causes of infectious disease in the chest and is associated with substantial morbidity and mortality in paediatric populations, particularly in low- and middle-income countries. Due to the difficulty in obtaining microbiological confirmation of pulmonary TB in children, diagnosis often relies on a combination of clinical and radiological findings. The early diagnosis of central nervous system TB is challenging with presumptive diagnosis heavily reliant on imaging. Brain infection can present as a diffuse exudative basal leptomeningitis or as localised disease (tuberculoma, abscess, cerebritis). Spinal TB may present as radiculomyelitis, spinal tuberculoma or abscess or epidural phlegmon. Musculoskeletal manifestation accounts for 10% of extrapulmonary presentations but is easily overlooked with its insidious clinical course and non-specific imaging findings. Common musculoskeletal manifestations of TB include spondylitis, arthritis and osteomyelitis, while tenosynovitis and bursitis are less common. Abdominal TB presents with a triad of pain, fever and weight loss. Abdominal TB may occur in various forms, as tuberculous lymphadenopathy or peritoneal, gastrointestinal or visceral TB. Chest radiographs should be performed, as approximately 15% to 25% of children with abdominal TB have concomitant pulmonary infection. Urogenital TB is rare in children. This article will review the classic radiological findings in childhood TB in each of the major systems in order of clinical prevalence, namely chest, central nervous system, spine, musculoskeletal, abdomen and genitourinary system.

Neonatal and Infant Lung Disorders: Glossary, Practical Approach, and Diagnoses.

A multitude of lung disorders ranging from congenital and genetic anomalies to iatrogenic complications can affect the neonate or the infant within the first year of life. Neonatal and infant chest imaging, predominantly by plain radiography and computed tomography, is frequently employed to aid in diagnosis and management; however, these disorders can be challenging to differentiate due to their broad-ranging, and frequently overlapping radiographic features. A systematic and practical approach to imaging interpretation which includes recognition of radiologic patterns, utilization of commonly accepted nomenclature and classification, as well as interpretation of imaging findings in conjunction with clinical history can not only assist radiologists to suggest the diagnosis, but also aid clinicians in management planning.

Perceived Impact of COVID-19 on Pediatric Radiology Departments Around the World: WFPI COVID-19 Task Force Survey Results from 6 Continents.

PURPOSE: To investigate how COVID-19 has impacted pediatric radiology practice around the world at the present time. MATERIALS AND METHODS: This study was based on a survey conducted by the World Federation of Pediatric Imaging (WFPI) COVID-19 task force. Pediatric radiology representatives from countries around the world were identified and asked to complete an electronic survey consisting of 17 questions related to the impact of, concerns surrounding, and education related to COVID-19 on pediatric radiology. For each outcome variable, a pair of 2-way frequency tables was constructed: one against COVID-19 prevalence, and another against region. Tests of independence of the tables' row and column factors were performed based on Fisher's exact test and odds ratios (OR) were estimated via logistic regression models corresponding to these 2-way tables. RESULTS: The survey (response rate 87%, 72/83) comprised representatives from 71 countries and Hong Kong across 6 continents. 66/72 respondents (92%) indicated that COVID-19 has resulted in moderate (21/72, 29%), significant (36/72, 50%), or complete (9/72, 13%) change in radiology departments/practices in their countries. The two most frequent concerns over the next four months were personal/family health (54/72, 75%) and exposure (48/72, 67%). 79% (57/72) of respondents indicated some level of discomfort in identifying pediatric COVID-19 imaging manifestations. Changes in resident education were reported by 68/72 (94%) respondents, and 22/72 (31%) were concerned that the likelihood of current trainees pursuing a career in pediatric radiology will be impacted. CONCLUSION: COVID-19 has had a substantial negative impact on pediatric radiology practice around the world.

Lesson of the month 2: Contusion confusion.

This lesson of the month highlights that certain radiology terminology may be used to report bleeding on head computerised tomography (CT) reports. On-call junior doctors should not be expected to interpret CT head images, so often their decisions will be based on the written report. The wording used can change the clinical decision and therefore the treatment given by a junior doctor. Clinical teams and junior doctors should be educated on terminology in relation to bleeding on CT head reports.

Imaging of the upper gastrointestinal tract: endoscopy or radiology?

Diseases of the upper gastrointestinal system are very common in the modern word with an increasing frequency over recent years. Clinical symptoms are rather non-specific and may be the result of simple gastro-oesophageal reflux or an advanced malignant process. Historically, the investigation of upper gastrointestinal complaints was based on plain radiography and contrast studies. Now, a flexible oesophagogastroduodeno-scopy has become the primary imaging modality in patients with upper gastrointestinal symptoms. Dynamic contrast studies and cross-sectional imaging remain the main diagnostic tests in certain pathological conditions and provide an additional and complementary information to endoscopy results.
