RESUMO
Perinatal venous infarcts are underrecognized clinically and at imaging. Neonates may be susceptible to venous infarcts because of hypercoagulable state, compressibility of the dural sinuses and superficial veins due to patent sutures, immature cerebral venous drainage pathways, and drastic physiologic changes of the brain circulation in the perinatal period. About 43% of cases of pediatric cerebral sinovenous thrombosis occur in the neonatal period. Venous infarcts can be recognized by ischemia or hemorrhage that does not respect an arterial territory. Knowledge of venous drainage pathways and territories can help radiologists recognize characteristic venous infarct patterns. Intraventricular hemorrhage in a term neonate with thalamocaudate hemorrhage should raise concern for internal cerebral vein thrombosis. A striato-hippocampal pattern of hemorrhage indicates basal vein of Rosenthal thrombosis. Choroid plexus hemorrhage may be due to obstruction of choroidal veins that drain the internal cerebral vein or basal vein of Rosenthal. Fan-shaped deep medullary venous congestion or thrombosis is due to impaired venous drainage into the subependymal veins, most commonly caused by germinal matrix hemorrhage in the premature infant and impeded flow in the deep venous system in the term infant. Subpial hemorrhage, an underrecognized hemorrhage stroke type, is often observed in the superficial temporal region, and its cause is probably multifactorial. The treatment of cerebral sinovenous thrombosis is anticoagulation, which should be considered even in the presence of intracranial hemorrhage. ©RSNA, 2024 Test Your Knowledge questions in the supplemental material and the slide presentation from the RSNA Annual Meeting are available for this article.

BACKGROUND: Physical literacy is a concept used to describe the combined physical, affective and cognitive capacities facilitating an active lifestyle. Physical activity participation is essential for children living with chronic medical conditions, but knowledge of physical literacy among this group is scarce. METHODS: An explanatory, sequential mixed methods design was used to comprehensively describe the physical literacies of children with chronic medical conditions (CMCs). Participants were recruited from paediatric cardiology, respirology/cystic fibrosis, neurology, haematology and endocrinology outpatient clinics. All participants completed the Canadian Assessment of Physical Literacy (2nd Edition), and those with higher and lower scores were invited to a semi-structured interview. A deductive-inductive thematic analysis was applied using Margaret Whitehead's conceptualization of physical literacy. RESULTS: Using normative strata, 80.0% of the 99 children assessed (mean age = 9.97 ± 1.3 years, 48% girls) were considered beginning or progressing in their overall physical literacy (mean score = 56.5 ± 13.8/100). Meanwhile, physical literacy informed participants' approach to new, active experiences and may have contributed to a strong sense of self. There was a significant difference between endocrinology and haematology patients on total physical literacy score (p = 0.03) but not domain scores. Participants scored high on motivation/confidence (mean = 22.9 ± 5.0/30) but obtained low physical competence (mean = 11.8 ± 5.6/30) and daily behaviour scores (n = 72, mean = 15.5 ± 7.1/30). Main themes represent salient experiences of children with CMCs within the domains of physical literacy, including their need to evaluate active contexts, self-regulate activity intensity and manage physical limitations. CONCLUSIONS: Children with CMCs can achieve recommended levels of physical literacy without meeting normative standards for physical competence. Participants would benefit from a physical literacy intervention that targets the development of bodily self-regulation skills and risk evaluation in active settings.

Despite its vigorous ability to detect and measure metabolic disturbances, 1H MRS remains underutilized in clinical practice. MRS increases diagnostic yield and provides therapeutic measures. Because many inborn metabolic errors are now treatable, early diagnosis is crucial to prevent or curb permanent brain injury. Therefore, patients with known or suspected inborn metabolic errors stand to benefit from the addition of MRS. With education and practice, all neuroradiologists can perform and interpret MRS notwithstanding their training and prior experience. In this two-part review, we cover the requisite concepts for clinical MRS interpretation including technical considerations and normal brain spectral patterns based on age, location, and methodology.

Proton MRS of the brain provides the ability to gather direct information regarding the metabolic status of the brain at the time of MRI. Although selective vulnerability of brain tissue may yield distinct imaging patterns in neurometabolic disorders, it is not uncommon for the brain MRI to be normal, nonspecific, or show ambiguous abnormalities among several possible diagnoses, metabolic, or otherwise. This review highlights childhood neurometabolic diseases in which 1H MRS may show diagnostic or suggestive metabolic profiles without complicated acquisition or postprocessing techniques.

BACKGROUND: Disease recurrence and progression remain major challenges for the treatment of non-muscle invasive bladder cancer. Narrow band imaging (NBI) is an optical enhancement technique that may improve resection of non-muscle invasive bladder cancer and thereby lead to better outcomes for people undergoing the procedure. OBJECTIVES: To assess the effects of NBI- and white light cystoscopy (WLC)-guided transurethral resection of bladder tumor (TURBT) compared to WLC-guided TURBT in the treatment of non-muscle invasive bladder cancer. SEARCH METHODS: We performed a comprehensive literature search of 10 databases, including the Cochrane Library, the Cochrane Database of Systematic Reviews, MEDLINE, Embase, several clinical trial registries, and grey literature for published and unpublished studies, irrespective of language. The search was performed per an a priori protocol on 3 December 2021. SELECTION CRITERIA: We included randomized controlled trials of participants with suspected or confirmed non-muscle invasive bladder cancer. Participants in the control group must have received WLC-guided TURBT alone (hereinafter simply referred to as 'WLC TURBT'). Participants in the intervention group had to have received NBI- and WLC-guided TURBT (hereinafter simply referred to as 'NBI + WLC TURBT'). DATA COLLECTION AND ANALYSIS: Two review authors independently selected studies for inclusion/exclusion, performed data extraction, and assessed risk of bias. We conducted meta-analysis on time-to-event and dichotomous data using a random-effects model in RevMan, according to Cochrane methods. We rated the certainty of evidence for each outcome according to the GRADE approach. Primary outcomes were time to recurrence, time to progression, and the occurrence of a major adverse event, defined as a Clavien-Dindo III, IV, or V complication. Secondary outcomes included time to death from bladder cancer and the occurrence of a minor adverse event, defined as a Clavien-Dindo I or II complication. MAIN RESULTS: We included eight studies with a total of 2152 participants randomized to the standard WLC TURBT or to NBI + WLC TURBT. A total of 1847 participants were included for analysis. Based on limited confidence in the time-to-event data, we found that participants who underwent NBI + WLC TURBT had a lower risk of disease recurrence over time compared to participants who underwent WLC TURBT (hazard ratio 0.63, 95% CI 0.45 to 0.89; I2 = 53%; 6 studies, 1244 participants; low certainty of evidence). No studies examined disease progression as a time-to-event outcome or a dichotomous outcome. There was likely no difference in the risk of a major adverse event between participants who underwent NBI + WLC TURBT and those who underwent WLC TURBT (risk ratio 1.77, 95% CI 0.79 to 3.96; 4 studies, 1385 participants; low certainty of evidence). No studies examined death from bladder cancer as a time-to-event outcome or a dichotomous outcome. There was likely no difference in the risk of a minor adverse event between participants who underwent NBI + WLC TURBT and those who underwent WLC TURBT (risk ratio 0.88, 95% CI 0.49 to 1.56; I2 = 61%; 4 studies, 1385 participants; low certainty of evidence). AUTHORS' CONCLUSIONS: Compared to WLC TURBT alone, NBI + WLC TURBT may lower the risk of disease recurrence over time while having little or no effect on the risks of major or minor adverse events.

Congenital genitourinary anomalies are among the most frequent types of birth defects in neonates. Some anomalies can be a significant cause of morbidity in infancy, while others remain asymptomatic even until adulthood and can be at times the only manifestation of a complex systemic disease. The spectrum of these anomalies results from the developmental insults that can occur at various embryologic stages, and an understanding of the formation of the genitourinary system is helpful in the evaluation and treatment of a child with a congenital genitourinary anomaly. Imaging plays an essential role in the diagnosis of congenital genitourinary anomalies and treatment planning. In this article, we highlight the embryologic and characteristic imaging features of various congenital genitourinary anomalies, demonstrate the utility of different imaging modalities in management, and review specific imaging modalities and protocols for image optimization.

Background. While advanced practice providers (APPs) are increasingly integrated into care delivery models, little is known about their impact in surgical settings. Given that many patients undergo surgery in multispecialty group practice settings, we examined the impact of APP integration into such practices on outcomes after major surgery. Methods. We used a 20% sample of national Medicare claims to identify 190 101 patients who underwent 1 of 4 major surgeries (coronary artery bypass graft [CABG], colectomy, major joint replacement, and cystectomy) at multispecialty group practices from 2010 through 2016. The level of APP integration was measured as the ratio of APPs to physicians within each practice. Rates of mortality, major complications, and readmission within 30 days of discharge after the index surgery were compared between patients treated in practices with low, medium, and high levels of APP integration using multivariable regression analysis. Results. Relative to patients treated in practices with low APP integration, those treated in practices with medium or high APP integration had significantly lower rates of mortality (2.4% [low integration] vs 1.9% [medium integration] vs 2.0% [high integration]; P < .01), major complications (34.1% [low] vs 31.2% [medium] vs 30.2% [high]; P < .01), and readmission (11.7% [low] vs 10.6% [medium] vs 10.1% [high]; P < .01). This relationship was consistent for virtually all outcomes when considering each surgery type individually. Conclusions. Integration of APPs into multispecialty group practices was associated with improved postoperative outcomes after major surgery. Future research should identify the mechanisms by which APPs improve outcomes to inform optimal utilization.

INTRODUCTION: The failure rate of Pavlik harness treatment for developmental dysplasia of the hip (DDH) has been reported as high as 55%. The purpose of this study is to investigate the effect of an inverted acetabular labrum on outcomes of Pavlik harness treatment for DDH. METHODS: A retrospective review was conducted on DDH patients at a tertiary care pediatric hospital from 2004 to 2016. DDH patients that underwent index treatment with Pavlik harness and had minimum 12 months follow-up were included. Medical charts were reviewed for demographics, treatment, and outcomes. Outcomes were compared between patients with an inverted labrum versus those without an inverted labrum. RESULTS: A total of 156 patients with 229 dysplastic hips were included. The mean age at initiation of Pavlik harness treatment was 1.9±1.4 months and mean follow-up was 37.7±23.0 months. Bilateral DDH was diagnosed in 46% (73/156) of patients. In all, 37% (75/229) of hips failed Pavlik harness index treatment. Second-line treatment was rigid hip abduction bracing in 91% (68/75) of hips, closed reduction in 5% (4/75) of hips, and open reduction in 4% (3/75) of hips. An inverted labrum was present in 10% (22/229) of all hips. The incidence of Pavlik harness treatment failure was 91% (20/22) in the inverted labrum group compared with 27% (55/207) in the control group (P<0.001). Closed or open reduction was required in 86% (15/22) of the inverted labrum group compared with 3% (7/207) of hips in the control group (P<0.001). The incidence of avascular necrosis was 18% (4/22) in hips with an inverted labrum compared with 0.4% (1/207) in the control group (P<0.001). CONCLUSIONS: In children with DDH undergoing index treatment in a Pavlik harness, the presence of an inverted acetabular labrum is strongly predictive of treatment failure. Dysplastic hips with an inverted labrum also have a significantly higher risk of requiring closed or open reduction and developing avascular necrosis compared with those without an inverted labrum. LEVEL OF EVIDENCE: Level III.

OBJECTIVE: Anterior lumbar interbody fusion (ALIF) is a powerful technique that provides wide access to the disc space and allows for large lordotic grafts. When used with posterior spinal fusion (PSF), the procedures are often staged within the same hospital admission. There are limited data on the perioperative risk profile of ALIF-first versus PSF-first circumferential fusions performed within the same hospital admission. In an effort to understand whether these procedures are associated with different perioperative complication profiles, the authors performed a retrospective review of their institutional experience in adult patients who had undergone circumferential lumbar fusions. METHODS: The electronic medicals records of patients who had undergone ALIF and PSF on separate days within the same hospital admission at a single academic center were retrospectively analyzed. Patients carrying a diagnosis of tumor, infection, or traumatic fracture were excluded. Demographics, surgical characteristics, and perioperative complications were collected and assessed. RESULTS: A total of 373 patients, 217 of them women (58.2%), met the inclusion criteria. The mean age of the study cohort was 60 years. Surgical indications were as follows: degenerative disease or spondylolisthesis, 171 (45.8%); adult deformity, 168 (45.0%); and pseudarthrosis, 34 (9.1%). The majority of patients underwent ALIF first (321 [86.1%]) with a mean time of 2.5 days between stages. The mean number of levels fused was 2.1 for ALIF and 6.8 for PSF. In a comparison of ALIF-first to PSF-first cases, there were no major differences in demographics or surgical characteristics. Rates of intraoperative complications including venous injury were not significantly different between the two groups. The rates of postoperative ileus (11.8% vs 5.8%, p = 0.194) and ALIF-related wound complications (9.0% vs 3.8%, p = 0.283) were slightly higher in the ALIF-first group, although the differences did not reach statistical significance. Rates of other perioperative complications were no different. CONCLUSIONS: In patients undergoing staged circumferential fusion with ALIF and PSF, there was no statistically significant difference in the rate of perioperative complications when comparing ALIF-first to PSF-first surgeries.

BACKGROUND: Coronary revascularization with bilateral internal mammary arteries is associated with increased long-term survival, but underutilized due to sternal wound infection concerns. Dedicated bilateral mammary grafting programs are typically high-volume academic or private practices, rather than lower-volume federal institutions whose results are not captured in the Society of Thoracic Surgeons database. Our institution used only single internal mammary arterial grafting in the year prior to implementing a dedicated bilateral grafting program using skeletonized technique. We describe our experience transitioning to bilateral mammary grafting and its impact on sternal wound infection. METHODS: Retrospective cohort study at San Francisco Veterans Affairs Medical Center in 200 patients undergoing first-time isolated, multi-vessel coronary artery bypass from August 2014 to October 2017. Sternal wound infection was defined broadly to include any patient receiving antibiotics for suspicion of sternal infection. Patients were followed for wound complications until 3 post-operative months. RESULTS: Of 200 total patients, 45.5% (n=91) were diabetic, 44% (n=88) had BMI >30, and 61.5% (n=123) underwent bilateral mammary grafting. Bilateral mammary grafting population had 2.4% (n=3/123) deep sternal wound infection with 1.6% (n=2/123) requiring sternal reconstruction while single mammary population had 1.3% (n=1/77, p=1.0). Bilateral mammary grafting population had 6.5% (n=8/123) superficial sternal wound infection compared to 5.2% (n=4/77, p=0.77) in single mammary grafting population. CONCLUSIONS: Transitioning to high rates of bilateral mammary utilization was possible in a year with low rates of complications. Based on our experience, surgeons should consider adopting a skeletonized bilateral mammary grafting approach given potential long-term survival benefit.
RESUMO
PURPOSE: To assess the feasibility of ferumoxytol-enhanced anesthesia-free cardiac MRI in neonates and young infants for complex congenital heart disease (CHD). MATERIALS AND METHODS: With Institutional Review Board approval, 21 consecutive neonates and young infants (1 day to 11 weeks old; median age of 3 days) who underwent a rapid two-sequence (MR angiography [MRA] and four-dimensional [4D] flow) MRI protocol with intravenous ferumoxytol without sedation (n = 17) or light sedation (n = 4) at 3 Tesla (T) (except one case at 1.5T) between June 2014 and February 2016 were retrospectively identified. Medical records were reviewed for indication, any complications, if further diagnostic imaging was performed after MRI, and surgical findings. Two radiologists scored the images in two sessions on a 5-point scale for overall image quality and delineation of various anatomical structures. Confidence interval of proportions for likelihood of requiring additional diagnostic imaging after MRI was determined. For the possibility of reducing the protocol to a single rapid sequence, Wilcoxon-rank sum test was used to assess whether 4D flow and MRA significantly differed in anatomical delineation. RESULTS: One of 21 patients (4.8%, 80% confidence interval 0-11%) required additional imaging, a computed tomography angiography to assess lung parenchyma and peripheral pulmonary arteries. Only 1 of 13 patients (7.7%) with operative confirmation had a minor discrepancy between radiology and operative reports (80% confidence interval 0-17%). 4D flow was significantly superior to MRA (P < 0.05) for the evaluation of systemic arteries, valves, ventricular trabeculae, and overall quality. Using Cohen's kappa coefficient, there was good interobserver agreement for the evaluation of systemic arteries by 4D flow (κ = 0.782), and systemic veins and pulmonary arteries by MRA (κ > 0.6). Overall 4D flow measurements (mean κ = 0.64-0.74) had better internal agreement compared with MRA (mean κ = 0.30-0.64). CONCLUSION: Ferumoxytol-enhanced cardiac MRI, without anesthesia, is feasible for the evaluation of complex CHD in neonates and young infants, with a low likelihood of need for additional diagnostic studies. The decreased risk by avoiding anesthesia must be balanced against the potential for adverse reactions with ferumoxytol. LEVEL OF EVIDENCE: 2 J. MAGN. RESON. IMAGING 2017;45:1407-1418.

PURPOSE: The relationship between parameters of brain functional networks and clinical indexes is unclear so far in patients with diabetic retinopathy (DR). This paper is to investigate this. METHODS: Twenty-one patients with different grades of DR and 21 age- and sex-matched healthy controls were enrolled from August 2012 to September 2014. The clinical indexes recorded included DR grade, duration of diabetes, HbA1c, diabetic foot screen, fasting plasma glucose, insulin, Homa-ß, Homa-IR, insulin sensitive index (ISI), Mini-Mental State Examination (MMSE), and patient sex and age. Subjects were scanned using 3-T MR with blood-oxygen-level-dependent and 3D-FSPGR sequences. MR data was analyzed via preprocessing and functional network construction, and quantified indexes of network (clustering coefficient, characteristic path length, global efficiency, degree distribution, and small worldness) were evaluated. Statistics consisted of ANOVA and correlation. RESULTS: There were significant differences between patients and controls among clustering coefficient, characteristic path length, degree distribution, and small worldness parameters (P < 0.05). MMSE scores negatively correlated with characteristic path length, and Hb1Ac negatively correlated with small worldness. MMSE, duration of diabetes, diabetic foot screen, fasting plasma glucose, insulin, Homa-ß, Homa-IR, ISI, DR grade, and patient age, except from Hb1Ac, correlated with degree distribution in certain brain areas. CONCLUSION: Brain functional networks are altered, specifically in the areas of visual function and cognition, and these alterations may reflect the severity of visual weakness and cognitive decline in DR patients. Moreover, the brain networks may be affected both by long-standing and instant clinical factors.

BACKGROUND: Electronic consultations (eConsult) allow for communication between primary care providers and specialists in an asynchronous manner. This study examined provider satisfaction, topics of interest, and efficiency of eConsult in pediatric hematology/oncology in Ottawa, Canada. METHODS: We conducted a cross-sectional assessment of all eConsult cases directed to pediatric hematology/oncology specialists using the Champlain BASE (Building Access to Specialists through eConsultation) eConsult service from June 1, 2014 to May 31, 2016. RESULTS: There were 1064 eConsults to pediatrics during the study timeperiod and pediatric hematology/oncology consults accounted for 8% (85). During the same study timeperiod, 524 consults were seen in the pediatric hematology/oncology clinic. The majority of the eConsults were for hematology (90.5%) in contrast to oncology topics (9.5%). The most common topics were anemia, hemoglobinopathy, bleeding disorder, and thrombotic state. Primary care providers rated the eConsult service very highly, and their comments were very positive. The eConsult service resulted in deferral of 40% of consults originally contemplated to require a face-to-face specialist visit. CONCLUSIONS: This study showed successful implementation and use of the eConsult service for pediatric hematology/oncology and resulted in avoidance of a large number of face-to-face consultation. The common topics identified areas for continuing medical education.

Psychosocial health issues are common among children with cardiac diagnoses. Understanding parent and child perceptions is important because parents are the primary health information source. Significant discrepancies have been documented between parent/child quality-of-life data but have not been examined among psychosocial diagnostic instruments. This study examined agreement and discrepancies between parent and child reports of psychosocial health and quality of life in the paediatric cardiology population. Children (n=50, 6-14 years) with diagnoses of CHDs (n=38), arrhythmia (n=5), cardiomyopathy (n=4), or infectious disease affecting the heart (n=3) were enrolled, completing one or more outcome measures. Children and their parents completed self-reports and parent proxy reports of quality of life - Pediatric Quality of Life Inventory - and psychosocial health - Behavioral Assessment Scale for Children (Version 2). Patients also completed the Multidimensional Anxiety Scale for Children. Associations (Pearson's correlations, Intraclass Correlation Coefficients) and differences (Student's t-tests) between parent proxy reports and child self-reports were evaluated. Moderate parent-child correlations were found for physical (R=0.33, p=0.03), school (R=0.43, p<0.01), social (R=0.36, p=0.02), and overall psychosocial (R=0.43, p<0.01) quality of life. Parent-child reports of externalising behaviour problems, for example aggression, were strongly correlated (R=0.70, p<0.01). No significant parent-child associations were found for emotional quality of life (R=0.25, p=0.10), internalising problems (R=0.17, p=0.56), personal adjustment/adaptation skills (R=0.23, p=0.42), or anxiety (R=0.07, p=0.72). Our data suggest that clinicians caring for paediatric cardiac patients should assess both parent and child perspectives, particularly in relation to domains such as anxiety and emotional quality of life, which are more difficult to observe.

BACKGROUND: Although mucolipidosis type II has similar metabolic abnormalities to those found in all the mucopolysaccharidoses and mucolipidoses, there are distinctive diagnostic radiographic changes of mucolipidosis II in the perinatal/newborn/infant period. OBJECTIVE: To describe the early characteristic radiographic changes of mucolipidosis II and to document when these changes manifest and resolve. MATERIALS AND METHODS: We retrospectively reviewed radiographs and clinical records of 19 cases of mucolipidosis II from the International Skeletal Dysplasia Registry (1971-present; fetal age to 2½ years). A radiologist with special expertise in skeletal dysplasias evaluated the radiographs. RESULTS: The most common abnormalities were increased vertebral body height (80%, nonspecific), talocalcaneal stippling (86%), periosteal cloaking (74%) and vertebral body rounding (50%). Unreported findings included sacrococcygeal sclerosis (54%) and vertebral body sclerosis (13%). Rickets and hyperparathyroidism-like (pseudohyperparathyroidism) changes (rarely reported) were found in 33% of cases. These changes invariably started in the newborn period and resolved by 1 year of age. The conversion from these early infantile radiographic features to dysostosis multiplex changes occurred in 41% of cases, and within the first year after birth. CONCLUSION: Several findings strongly suggest the diagnosis of mucolipidosis II, including cloaking in combination with one or more of the following radiographic criteria: talocalcaneal stippling, sacrococcygeal or generalized vertebral body sclerosis, vertebral body rounding, or rickets/hyperparathyroidism-like changes in the perinatal/newborn/infancy period. These findings are not found in the other two forms of mucolipidosis nor in any of the mucopolysaccharidoses.

Inflammatory pseudotumor is a generic term used to designate a heterogeneous group of inflammatory mass-forming lesions histologically characterized by myofibroblastic proliferation with chronic inflammatory infiltrate. Inflammatory pseudotumor is multifactorial in etiology and generally benign, but it is often mistaken for malignancy given its aggressive appearance. It can occur throughout the body and is seen in all age groups. Inflammatory pseudotumor has been described in the literature by many organ-specific names, resulting in confusion. Recently within this generic category of inflammatory pseudotumor, inflammatory myofibroblastic tumor has emerged as a distinct entity and is now recognized as a fibroblastic/myofibroblastic neoplasm with intermediate biological potential and occurring mostly in children. We present interesting pediatric cases of inflammatory myofibroblastic tumors given this entity's tendency to occur in children. Familiarity and knowledge of the imaging features of inflammatory pseudotumor can help in making an accurate diagnosis, thereby avoiding unnecessary radical surgery.

BACKGROUND: Numerous reports have described the clinical presentation of cardiac adverse events following immunization (AEFI) with COVID-19 vaccines but long-term outcome studies are limited, especially in the pediatric population. METHODS: This is a single center retrospective case series of pediatric patients with cardiac AEFI following the Pfizer/BioNTech mRNA COVID-19, diagnosed between May 2021 and May 2022, and managed following a standardized protocol. Follow up information is presented up to 12 months post diagnosis. The incidence rate of cardiac AEFI was estimated for Ottawa residents. RESULTS: All cases were male (N = 17) with an average age of 16 years (range = 12-17). The majority of cases occurred after the 2nd (12/17) or 3rd vaccine dose (4/17) and were manifested mostly as myopericarditis (15/17). Average interval between the 1st and 2nd vaccine (n = 12) doses was 38 days (21-69 days). All patients improved promptly on non-steroidal anti-inflammatory drugs without recurrence. Five patients reported negative impact on quality of life and mental health, including 2 cases that led to new vaccine hesitancy, not only to COVID-19 vaccine, but also to other routine vaccines. The rate of cardiac AEFI was estimated for residents of the city of Ottawa and found to be 12.01 cases (CI 90 5.98-21.68) per 100,000 doses following the 2nd dose and 16.56 cases (CI 90 5.66-37.90) per 100,000 doses following the 3rd dose for males aged 12 to 17 years. CONCLUSIONS: Twelve months following the AEFI, all patients clinically recovered from their myopericarditis, but some reported negative impact on quality of life and mental health, including new vaccine hesitancy. This highlights the importance for timely and systematic evaluation of AEFI and the need to provide support, follow up and vaccine counseling in individuals experiencing an AEFI.
RESUMO
We report a case of multisystem Langerhans cell histiocytosis in a pediatric patient with central nervous system involvement, highlighting F-18(FDG) uptake characteristics of dural sites of disease. We also highlight the advantages of functional data offered by FDG-PET as a useful follow-up tool to assess viability and, therefore, treatment response of previously known central nervous system lesions. The utility of recognizing characteristic patterns of FDG uptake in dural disease is also applicable in cases of diagnostic uncertainty, such as when evaluating isolated dural lesions or when distinguishing between Langerhans cell histiocytosis and similar appearing lesions such as meningiomas.
