RESUMEN
BACKGROUND: Lung ultrasound is a well-established technique to assess extravascular lung water, a proxy for volume status, in the adult population. Despite its utility, the data are limited supporting the use of ultrasound to evaluate fluid volume status among pediatric patients. Our study uses a simplified ultrasound protocol to evaluate changes in extravascular lung water, represented by b-lines, among pediatric patients undergoing hemodialysis. METHODS: This prospective single-center study included children from birth to 18 years of age. The number of b-lines per ml/kg of fluid removed was compared prior to, at the midpoint, and following termination of dialysis. An 8-zone protocol was utilized, and b-lines were correlated to hemoconcentration measured by the CRIT-LINE® hematocrit. RESULTS: Six patients with a total of 26 hemodialysis sessions were included in this study. The b-line measurements post-dialysis were 2.27 (p < 0.001; 94%CI -3.31, -1.22) lower relative to pre-dialysis. The number of b-lines was reduced by 1.69 (p < 0.001; -2.58, -0.80) between pre-dialysis and at the midpoint of dialysis and by 0.58 (p = 0.001; -0.90, -0.24) between the midpoint of dialysis and post-dialysis. A 1 mL/kg fluid loss correlated to a decrease in the original b-lines by 0.079. An inverse relationship (r = -0.54; 95% CI: -0.72, -0.34; p < 0.001) was noted between the b-lines and the patients' hematocrit levels. CONCLUSIONS: A simplified 8-zone ultrasound protocol can assess fluid volume change in real time and correlates with hematocrit levels obtained throughout dialysis. This provides a valuable method for monitoring fluid status in volume overloaded patient populations. A higher resolution version of the Graphical abstract is available as Supplementary information.

BACKGROUND: Echocardiographic markers of ACR are essential for early recognition and management. The literature's primary focus has been on the LV with little attention given to the RV. This study aimed to investigate echocardiographic right ventricular indices in the detection of ACR and to evaluate their utility as prognostic indicators of graft integrity. METHODS: We performed a retrospective chart review of children with biopsy-proven ACR following orthotopic heart transplant and an echocardiogram within 24 h of biopsy. Selected echocardiographic markers were compared at baseline, during ACR, and at follow-up. RESULTS: Forty-eight patients (56% male) had a total of 84 ACR episodes. Decrease in RV FAC (mean - 17.1%, p < .001) and TAPSE (mean - 8.9%, p < .001) with increase in left ventricular posterior wall thickness in diastole and systole (LVPWTd) (mean + 9.0%, p = .012) and LVPWTs (mean + 8.3%, p = .016) were found during ACR. Interestingly, these parameters improved following the episode of rejection. Additionally, these markers were compared after recovery between children with and without graft failure. RV dysfunction (FAC and TAPSE) and changes in LV posterior wall thickness were not found to have prognostic significance for graft integrity in children with heart transplantation. CONCLUSIONS: RV echocardiographic functional parameters should be considered as valuable adjuncts in rejection surveillance. Further, the presence of RV dysfunction does not have prognostic significance for graft integrity but is reversible as ongoing damage was not detectable by such.

IMPORTANCE: Single ventricle CHD affects about 5 out of 100,000 newborns, resulting in complex anatomy often requiring multiple, staged palliative surgeries. Paediatricians are an essential part of the team that cares for children with single ventricle CHD. These patients often encounter their paediatrician first when a complication arises, so it is critical to ensure the paediatrician is knowledgeable of these issues to provide optimal care. OBSERVATIONS: We reviewed the subtypes of single ventricle heart disease and the various palliative surgeries these patients undergo. We then searched the literature to detail the general paediatrician's approach to single ventricle patients at different stages of surgical palliation. CONCLUSIONS AND RELEVANCE: Single ventricle patients undergo staged palliation that drastically changes physiology after each intervention. Coordinated care between their paediatrician and cardiologist is requisite to provide excellent care. This review highlights what to expect when these patients are seen by their paediatrician for either well child visits or additional visits for parental or patient concern.

IMPORTANCE: Paediatricians play an integral role in the lifelong care of children with CHD, many of whom will undergo cardiac surgery. There is a paucity of literature for the paediatrician regarding the post-operative care of such patients. OBSERVATIONS: The aim of this manuscript is to summarise essential principles and pertinent lesion-specific context for the care of patients who have undergone surgery or intervention resulting in a biventricular circulation. CONCLUSIONS AND RELEVANCE: Familiarity with common issues following cardiac surgery or intervention, as well as key details regarding specific lesions and surgeries, will aid the paediatrician in providing optimal care for these patients.

Due to the COVID-19 pandemic, there has been an increased interest in telehealth as a means of providing care for children by a pediatric cardiologist. In this article, we provide an overview of telehealth utilization as an extension of current pediatric cardiology practices and provide some insight into the rapid shift made to quickly implement these telehealth services into our everyday practices due to COVID-19 personal distancing requirements. Our panel will review helpful tips into the selection of appropriate patient populations and specific cardiac diagnoses for telehealth that put patient and family safety concerns first. Numerous practical considerations in conducting a telehealth visit must be taken into account to ensure optimal use of this technology. The use of adapted staffing and billing models and expanded means of remote monitoring will aid in the incorporation of telehealth into more widespread pediatric cardiology practice. Future directions to sustain this platform include the refinement of telehealth care strategies, defining best practices, including telehealth in the fellowship curriculum and continuing advocacy for technology.

Neurodevelopmental impairment is a common and important long-term morbidity among infants with congenital heart disease (CHD). More than half of those with complex CHD will demonstrate some form of neurodevelopmental, neurocognitive, and/or psychosocial dysfunction requiring specialized care and impacting long-term quality of life. Preventing brain injury and treating long-term neurologic sequelae in this high-risk clinical population is imperative for improving neurodevelopmental and psychosocial outcomes. Thus, cardiac neurodevelopmental care is now at the forefront of clinical and research efforts. Initial research primarily focused on neurocritical care and operative strategies to mitigate brain injury. As the field has evolved, investigations have shifted to understanding the prenatal, genetic, and environmental contributions to impaired neurodevelopment. This article summarizes the recent literature detailing the brain abnormalities affecting neurodevelopment in children with CHD, the impact of genetics on neurodevelopmental outcomes, and the best practices for neonatal neurocritical care, focusing on developmental care and parental support as new areas of importance. A framework is also provided for the infrastructure and resources needed to support CHD families across the continuum of care settings.

The most common congenital lung malformations are congenital pulmonary airway malformations and pulmonary sequestrations. Many surgeons advocate resection to prevent complications of infection, malignancy, and pneumothorax. The standard of care is lobectomy, but segmentectomy and embolization alone have been reported. These methods avoid the complications of lobectomy but are not widely practiced due to concerns about incomplete resection or involution of the lesion. We present a novel approach to the treatment of a pulmonary sequestration in a 7-month-old male using preoperative embolization followed by a sublobar pulmonary resection. The embolization clearly demarcated the affected lung intraoperatively, thereby facilitating complete removal of the lesion with a segmental lung resection rather than complete lobectomy.
RESUMEN
Current guidelines for adults with atrial switch repair recommend baseline cardiovascular magnetic resonance (CMR) for assessment of ventricular size and function, systemic and venous baffle obstruction and leaks, and valvular function. It also recommends transthoracic echocardiography (TTE) for outpatient follow up. Many such patients with implanted cardiac devices may need cardiac computed tomography (CCT) when CMR is not feasible. This study reviews and compares CMR, transesophageal echocardiography (TEE), CCT, cardiac catheterization with angiography and TTE in detection of baffle problems in patients after atrial switch operation. The medical records of patients who had at least one imaging study performed after atrial switch operation at our center from 2010 to 2020 were retrospectively reviewed. Results are reported as descriptive statistics for demographics and imaging findings. The principal outcome measure was detection of baffle leak and/or baffle stenosis. Fifty-seven patients had at least one cardiac imaging study after atrial switch operation (36 Senning and 21 Mustard operations) during the study period. Nearly 33% (19/57) had baffle complications of stenosis and/or baffle leaks identified. All 57 patients had TTE performed but baffle problems were noted by TTE in only 8 (14%) patients (7 baffle stenosis and 1 baffle leak). Of the 49 patients without known baffle problems by TTE, 24 had advanced imaging (TEE/CCT/CMR/angiography). Advanced imaging identified baffle problems in nearly half (11/24, 46%) of them (7 baffle leaks and 4 baffle stenosis). Baffle problems were present in (8/23) patients with transvenous cardiac devices. Baffle complications are common after atrial switch operations and in our study occur in 1/3rd of the patients. However, TTE is not sensitive enough to recognize these complications. Advanced imaging for detection of baffle complications should be considered in all patients after atrial switch operation.

Background Recent evaluation of rheumatic heart disease (RHD) mortality demonstrates disproportionate disease burden within the United States. However, there are few contemporary data on US children living with acute rheumatic fever (ARF) and RHD. Methods and Results Twenty-two US pediatric institutions participated in a 10-year review (2008-2018) of electronic medical records and echocardiographic databases of children 4 to 17 years diagnosed with ARF/RHD to determine demographics, diagnosis, and management. Geocoding was used to determine a census tract-based socioeconomic deprivation index. Descriptive statistics of patient characteristics and regression analysis of RHD classification, disease severity, and initial antibiotic prescription according to community deprivation were obtained. Data for 947 cases showed median age at diagnosis of 9 years; 51% and 56% identified as male and non-White, respectively. Most (89%) had health insurance and were first diagnosed in the United States (82%). Only 13% reported travel to an endemic region before diagnosis. Although 96% of patients were prescribed secondary prophylaxis, only 58% were prescribed intramuscular benzathine penicillin G. Higher deprivation was associated with increasing disease severity (odds ratio, 1.25; 95% CI, 1.08-1.46). Conclusions The majority of recent US cases of ARF and RHD are endemic rather than the result of foreign exposure. Children who live in more deprived communities are at risk for more severe disease. This study demonstrates a need to improve guideline-based treatment for ARF/RHD with respect to secondary prophylaxis and to increase research efforts to better understand ARF and RHD in the United States.

Recent produce-related outbreaks have been receiving heightened media coverage, which has increased public concern toward the safety of fresh fruits and vegetables. In response, the microbial contamination of Ontario-grown fresh fruits and vegetables was evaluated by the Ontario Ministry of Agriculture, Food and Rural Affairs during the summer of 2004. Prior to this survey, information specific to the microbial contamination of Ontario-produced fruits and vegetables was limited. This nonregulatory survey had two objectives: (i) to obtain a general microbiological profile of selected fruits and vegetables produced in Ontario and (ii) to use the information and knowledge gained from this survey to direct and support future on-farm food safety research and food safety programs to manage potential risks. In all, 1,183 samples, including muskmelon (151), scallions and green onions (173), leaf lettuce (263), organic leaf lettuce (112), head lettuce (155), parsley (127), cilantro (61), and fresh market tomatoes (141), were collected and analyzed. Samples were analyzed for Salmonella, Shigella, and generic E. coli. Enrichment cultures positive for E. coli were further assessed for verotoxigenicity. One sample each of Roma tomato and organic leaf lettuce were positive for Salmonella, with no samples yielding Shigella or verotoxigenic E. coli. The E. coli prevalence was highest in parsley (13.4%), followed by organic leaf lettuce (11.6%), leaf lettuce (6.5%), scallions (6.4%), cilantro (4.9%), muskmelon (1.3%), head lettuce (0%), and fresh market tomatoes (0%). These findings, in combination with foodborne illness data, will help target those commodities that require more focused risk mitigation efforts.

BACKGROUND: Single-incision pediatric endosurgery is gaining popularity, especially for abdominal operations. Several reports in the literature support the feasibility of the single-incision approach in pediatric laparoscopy. Here we compare our experience with single-incision thoracoscopic surgery (SITS) to traditional multiple-incision video-assisted thoracoscopic surgery (VATS) in children. METHODS: A chart review of all patients who underwent SITS at our institution was performed. The same number of demographically matched VATS case controls were selected from a pool of patients operated on during the same time period. Operative time, time until chest tube removal, length of stay, complications, and any need for further intervention were recorded. Statistical analysis was done by Student's t-test using Instat 3. RESULTS: Fourteen SITS procedures were performed during the study period. These patients were compared with 14 VATS case controls. Both groups were similar with regard to age, weight, sex, and procedures performed. The mean operative time in the SITS group was 84 ± 43 minutes versus 64 ± 30 in the VATS group (P=.18). Days until chest tube removal was 4 ± 2.2 in the SITS group and 2.8 ± 1.4 in the VATS group (P=.09). Length of hospital stay was 5.5 ± 4.4 days in the SITS group versus 7.2 ± 8.6 in the VATS group (P=.51). There were no intraoperative complications and no procedure conversions in either group. One SITS patient who underwent a wedge resection and mechanical pleurodesis for a spontaneous pneumothorax was readmitted for a recurrent pneumothorax and required a reoperation. CONCLUSIONS: Our experience demonstrates that there are no statistically significant differences in operative time, time until chest tube removal, and length of hospital stay when comparing SITS to VATS in children. We believe that SITS is an equivalent procedure that allows for fewer scars when compared with traditional multiple-incision VATS in children.
