Pediatric Scaphoid Nonunions: Does Insurance Status Play a Role?

Objective: There are no studies that evaluate the effects that insurance or socioeconomic status may have on treatment and outcomes of scaphoid nonunions in children. We evaluated whether there is an association between insurance status and (1) time from injury to hand surgeon evaluation, (2) time from specialist evaluation to surgery, and (3) postoperative outcomes of scaphoid fracture nonunions in children. Methods: A chart review was performed for patients who underwent surgical treatment of scaphoid fracture nonunion from January 2015 and April 2021 at a large tertiary care pediatric hospital. Underinsured patients were defined as those with no medical insurance or Medicaid/state-funded insurance. Results: There were 21 privately insured patients and 17 patients who were underinsured. There was no difference in age, race, or fracture characteristics between the two groups. The mean time between injury and hand surgeon evaluation was 192 SD 195 days for the privately insured group compared with 155 SD 205 days for the underinsured group (P = 0.57). The mean time between specialist evaluation and surgical treatment was 35 SD 54 days for the privately insured group and 31 SD 31 days for the underinsured group (P = 0.82). Union was achieved in 80% of patients with private insurance compared with 88% of underinsured patients after primary surgery (P = 0.67). There was no difference detected in the proportion of patients who had residual pain (15% vs 19%), range of motion deficits (38% vs 40%), strength deficit (6% vs 7%), and return to activity (94% vs 93%) between privately insured and underinsured patients, respectively (P = 1.00). Conclusions: There was no difference in time from injury to specialist evaluation, time from evaluation to surgery, or postoperative outcomes based on insurance status for pediatric patients with scaphoid fracture nonunions. Although insurance status was not associated with access to care for pediatric scaphoid fracture nonunions at our institution, this information may not be generalizable to other populations, including patients who sustain primary scaphoid fractures and who have not yet developed nonunions. Level of Evidence: Level III—retrospective cohort study.

Characteristics of hospital pediatricians and obstetricians/gynecologists working long hours in Tokushima, Japan: A cross-sectional study

Background This study aimed to determine the actual working conditions, including working hours and desired future working styles of hospital pediatricians and obstetricians/gynecologists (OB/GYNs) in Tokushima Prefecture. Method This cross-sectional study used a self-administered questionnaire. Pediatricians and OB/GYNs (n = 96) working at 14 hospitals in Tokushima Prefecture were surveyed. The questionnaire included items related to working hours, working status, number of medical institutions, task-shifting/task-sharing status, and preferred work style. Factors associated with work hours were analyzed. Results Approximately 40% and 10% of pediatricians and OB/GYNs worked ≥60 h/week and ≥80 h/week, respectively. Their weekly working hours were significantly positively associated with the number of nights and holidays worked and concurrent medical facilities they worked at. Multiple regression models showed that weekly working hours were significantly associated with working at night and day-off duties and the number of working medical institutions being worked at concurrently. Pediatricians and OB/GYNs who worked ≥60 h/week were not implementing a “multiple attending physician system” or “on-call system,” and task-shifting/task-sharing was inadequate. A significantly higher proportion of physicians who worked long hours (≥60 h/week or ≥80 h/week) wanted to reduce the number of night and day-off duties and work hours compared with those who did not. Conclusions The results of this study suggest that many pediatricians and OB/GYNs work long hours, and it is essential to improve their work environment, including task-shifting/task-sharing. Further enhanced recruitment and retention of hospital pediatricians and OB/GYNs is required. A detailed and large-scale study of pediatricians and OB/GYNs’ working environments is essential in the future.

Utility of acid citrate dextrose‐acidification for platelet volume reduction protocols in the transfusion service

AbstractBackgroundVolume‐reduced platelets can minimize circulatory overload, allergic transfusion reactions, or out‐of‐group plasma infusion. Our center adopted a volume reduction protocol that includes acidification with acid citrate dextrose solution A (ACD‐A) before centrifugation and without any rest period prior to resuspension allowing a better turnaround time for platelet issue.Study Design and MethodsThis report compares corrected count increments (CCIs) from full‐volume and ACD‐A acidified volume‐reduced human platelets in a retrospective study at a single hospital and in a mouse model.ResultsAt a pediatric tertiary care hospital, 530 patients received conventional apheresis platelets during the 20‐month study period. Among all patients, the expected 4‐h mean CCI was 9.8 (95% CI: 8.7, 10.9) for full‐volume platelets, and 8.8 (95% CI: 7.3, 10.6) for ACD‐acidified volume‐reduced platelets (p = .29). A statistically significant difference (p = .01) was identified in the expected 24‐h mean CCI: 6.3 (95% CI: 5.5–7.0) with full‐volume platelet, 4.7 (95% CI: 3.6–6.0) with ACD‐acidified volume‐reduced platelet. Limiting CCI calculations to patients with Hematology/Oncology/Hematopoietic Progenitor Cell Transplant diagnosis (n = 296, 56%) indicated a statistically significant difference in both 4‐ and 24‐h predicted CCIs, showing lower CCIs in ACD‐acidified volume‐reduced platelet, although these were still similar to the CCIs observed in all patients and considered to be clinically acceptable responses similar to other volume reduction protocols. The recovery of count‐adjusted, volume‐reduced platelets was significantly lower in mice, suggesting a procedure‐related defect.DiscussionACD‐A acidification of platelets before volume reduction decreases turnaround time for platelet issue and provides clinically allowable 4‐h and 24‐h platelet increments.

Unilateral Vestibular Hypofunction in an Adolescent: Case Report and Literature Review

Objective − The report presents a case of an adolescent girl with vertigo resulting from unilateral vestibular hypofunction, diagnosed after extensive pediatric and otorhinolaryngological evaluations.Case Report − A seventeen-year-old female adolescent sought medical assistance at the pediatric emergency hospital service on several occasions within one year due to feelings of weakness and darkened vision occurring during abrupt standing, exposure to heat, and stress. Symptoms were initially attributed to school obligations, low blood pressure, and the menstrual cycle. After an episode that also involved a brief loss of consciousness, an extensive neurological evaluation was conducted, excluding epileptogenic causes. Subsequent diagnostic procedures included evoked visual potential tests, psychological assessments, laboratory blood tests, thyroid hormone assays, and Borrelia burgdorferi serology, all yielding normal results. Finally, otorhinolaryngological examinations were performed, including pure tone audiometry, tympanometry, video head impulse tests, videonystagmography, and vestibular evoked myogenic potential tests. These tests indicated symptoms arising from unilateral labyrinthine hypofunction of the inner ear. The patient underwent vestibular rehabilitation, resulting in symptom resolution and confirmed functional recovery.Conclusion − Diagnosing vertigo in adolescence is challenging, as impaired balance can manifest as a symptom of various diseases. Presentation with atypical symptoms for peripherally caused balance disorders complicates diagnosis. Otorhinolaryngologists and audio-vestibular diagnosticians play pivotal roles in establishing accurate diagnoses.

The digital health landscape at children’s hospitals in Canada

ABSTRACT Objectives Canadian hospitals have historically lagged behind peer nations in terms of adoption of digital health tools. The aim of this study was to assess the current state of adoption of digital health tools at children’s hospitals in Canada. Methods We conducted an online survey of Canadian pediatric tertiary-care hospitals between January and July 2023. The 35-item questionnaire was administered in English and French. Hospital characteristics, informatics infrastructure data and electronic health record (EHR) functionality data were summarized using descriptive statistics. Results The survey was completed by 15 of the 17 (88.2%) pediatric hospitals in Canada. All institutions had an EHR with 10 (66.6%) being fully digitized and five (33.3%) being partially digitized. Funding and availability of clinicians with expertise in clinical informatics were cited as barriers to implementing digital health tools. The availability of core EHR functionalities ranged from 53.3% for medication to 100% for the presence of a laboratory and radiology information system. Only five (33.3%) institutions reported that they had a patient portal. Discussion While all hospitals in this study had an EHR, functionalities varied greatly between centers. Canada lags behind the United States in terms of adoption of digital health tools such as patient portals likely due to governmental mandates and incentives, and a focus on cultivating a physician informatics workforce. Conclusion Canadian pediatric hospitals lag behind peer institutions in digital maturity. This study highlights the perceived need from hospitals for policies, funding, and resources from the Canadian government to help increase the uptake of comprehensive EHRs.

Benefit-finding in children with advanced cancer and their parents.

Although pediatric cancer often causes significant stress for families, most childhood cancer survivors are resilient and do not exhibit severe or lasting psychopathology. Research demonstrates some survivors may report benefit-finding or positive outcomes following this stressful life event. However, considerably less research has included families of children who are unlikely to survive their illness. Thus, this study investigated benefit-finding among parents and their children with advanced cancer, as well as associated demographic and medical factors. Families (N = 72) of children with advanced cancer (ages 5-25) were recruited from a large pediatric hospital. Advanced cancer was defined as relapsed or refractory disease, an estimated prognosis of <60%, or referral to end-of-life care. Participants completed a demographic survey and the Benefit Finding Scale at enrollment. Children, mothers, and fathers reported moderate to high benefit-finding scores. Correlations between family members were weak and non-significant. Children reported significantly higher benefit-finding than fathers. Demographic and medical factors were not associated with benefit-finding in children, mothers, or fathers. Families of children with advanced cancer reported moderate to high benefit-finding regardless of background or medical factors. Children identified benefits of their cancer experience independent of the experiences of their mothers and fathers. Larger studies should continue to examine factors associated with positive and negative outcomes in the context of childhood cancer to inform interventions.

Clinical-histological correlation of various symptoms in the diagnosis of pediatric Crohn's disease.

Crohn's disease (CD) is a relapsing-remitting inflammatory bowel disease (IBD) affecting the gastrointestinal tract. Its symptoms are nonspecific, with weight loss, diarrhea, and abdominal pain being classic, though their diagnostic utility is controversial (2). We evaluated the clinical-pathological association of different symptoms in CD through an analytical study of patients under 15 years of age who underwent esophagogastroduodenoscopy and ileocolonoscopy in a pediatric hospital between 2015-2022 due to suspected IBD.

Differential diagnosis of visceral leishmaniasis in children: a five-year retrospective study at a pediatric referral hospital.

Visceral leishmaniasis (VL) is a zoonotic disease caused by protozoa of the genus Leishmania and is transmitted by sandflies of the genus Lutzomyia. Children under 15 years are disproportionately affected. In pediatric patients, the clinical and laboratory features of VL often overlap with those of other infectious and hematology-oncology diseases, making differential diagnosis challenging. Rapid and accurate identification of VL is critical for effective treatment. This study aimed to evaluate the epidemiological, clinical, and laboratory characteristics of pediatric patients initially suspected of having VL and to compare their final diagnoses upon discharge from a referral hospital. We retrospectively analyzed medical records of children with suspected VL, admitted between July 2014 and June 2019. Infectious diseases were confirmed in 61% of cases (86 patients), with VL confirmed in 55 cases. Hematology-oncology diseases were the second most common diagnosis, affecting 22.7% of patients (32 cases). Comparisons between the VL-confirmed group and those with other diagnoses revealed no significant age difference (p = 0.690). However, female sex, spleen size, and leukopenia were identified as significant predictors of VL. Female sex, spleen size, and leukopenia were key predictors for differentiating VL from other pediatric diseases in a referral center in the Northeast Region of Brazil.

Abstract 4134957: Survival and Cardiac Recovery in Pediatric Dilated Cardiomyopathy: A Long-term Cohort Study of Risk Factors, Prognosis, and Health Outcomes Followed into Adulthood

Background: Dilated cardiomyopathy (DCM) is the most common cause of pediatric heart failure (HF), but there is limited literature on its long-term prognosis and treatment outcomes. We examined risk factors for long-term morbidity and mortality and outcomes of care in childhood-onset DCM. Methods: Electronic medical records from a tertiary care pediatric hospital (SickKids, Toronto, Canada) were used to retrospectively follow children ages 0–18 years with DCM from January 1, 2001 to July 1, 2017. Provincial healthcare administrative data was used to monitor outcomes recorded outside of SickKids, following patients during the same time period and into adulthood (age &gt;18 years) until August 31, 2023. We compared DCM cases, with or without echocardiographic recovery (LVEDD z score &lt; 2 and LVEF ≥ 55%), and controls matched on sex, age, and urban/rural residence on a range of health and health service outcomes. Primary outcomes included all-cause mortality, heart transplant (HT), and inpatient admission for HF. Among cases, Cox proportional hazards regression with backwards selection was used to identify demographic, disease, and treatment characteristics associated with each primary outcome, with candidate variables selected based on univariate analysis and clinical judgment. Results: We studied 156 patients with DCM and 780 controls for a median of 14.8 years. Median age at the end of follow-up was 16.2 years. Compared with controls, DCM cases had higher rates of all-cause death, HT, and HF admission (all P &lt;0.001), as well as chronic kidney disease ( P &lt;0.001) and diabetes ( P =0.002). Compared to cases with recovered DCM (n=53), non-recovered cases had higher rates of death, HT, and HF admission (all P &lt;0.001). On multivariable analysis, beta blockers were associated with reduced mortality risk (HR 0.343, 95% CI 0.162–0.727). Using any HF medication (HR 0.205, 95% CI 0.102–0.412) and living in an urban versus a rural area (HR 0.166, 95% CI 0.048–0.573) decreased HT risk. Idiopathic (HR 4.16, 95% CI 1.42–12.2) or sarcomeric mutation-related (HR 9.86, 95% CI 2.30–42.3) DCM were associated with higher HT risk than myocarditis-related DCM. Conclusions: While childhood DCM is associated with long-term adverse health and increased health care utilization, patients who recover have improved morbidity and mortality. Treatment (e.g. medication or access to urban specialist care) was associated with lower mortality and HT risk in DCM.

Lyme serology in non-endemic countries: Why do we request it and what do we find?

The primary objectives of our research were to analyze Lyme serology results from pediatric patients, identify the clinical reasons for ordering these tests, and assess the clinical relevance of the serology results in the context of Lyme disease. Our study, conducted at a reference pediatric hospital in a non-endemic region for Lyme disease, included all pediatric patients for whom Lyme serology was requested. ELISA and Western blot results were documented. Presenting complaints and findings at the time of admission were recorded. Diagnostic tests were categorized as first-step tests if conducted during the initial visit. Subsequent tests, sent due to the inability to establish a diagnosis based on the results of the first-line tests, were defined as second and third-step tests, respectively. 219 patients, for whom Lyme serology had been requested for varying reasons, were included in our study. The most prevalent complaints and indications observed in the presentations of patients with serology requests were as follows: headache(24.7%), paresis/paresthesia(14.6%), and painful or blurred vision(13.2%). Serology was primarily requested in the presence of neurological(59.4%) and ocular symptoms(13.2%). 68% of the tests were requisitioned during the initial consultation. Nevertheless, it was discerned that no patient received a diagnosis of Lyme disease. According to the guidelines, Lyme serology should only be performed when there is a realistic possibility of exposure to infected ticks, particularly in patients who have had untreated erythema migrans or those with a history of a tick bite presenting with unexplained joint or neurological symptoms. Our data, in line with these guidelines, suggests that unnecessary Lyme serology testing in non-endemic areas, where exposure is highly unlikely, may lead to false-positive results and unnecessary follow-up testing, as illustrated by the high rate of false-positive ELISAs in our cohort.

Diagnosis and treatment of magnetic foreign bodies in the gastrointestinal tract: the experience of four centers

BACKGROUND: Magnetic foreign bodies in the gastrointestinal tract is a relatively rare problem in urgent pediatric surgery. Meanwhile, among cases with foreign bodies, they are the most difficult both in terms of timely diagnostics and timely treatment. There are no generally accepted therapeutic and diagnostic standards, and traditional algorithms of patient management are focused on the dynamic observation and are not correct. More so, algorithms described in the foreign literature contradict each other. The rate of surgical interventions and the risk of complications are high. Surgical tactics has many "white spots". All these issues remain open for discussion. AIM: To analyze the experience of four medical centers in the diagnostics and treatment of patients with magnetic foreign bodies in the gastrointestinal tract. METHODS: A retrospective analysis of diagnostic and treatment techniques applied in patients with magnetic foreign bodies in their gastrointestinal tract from four pediatric surgical hospitals in 2010–2023 was made. In the study there were patients with neodymium magnetic balls from the constructor (38 patients, 50%), neodymium magnets of other shapes and for other purposes (30 patients, 39.5%), ferrite magnets (6 patients, 7.9%), unknown types of magnets (2 patients, 2.6%). RESULTS: Patients’ average age was (4±3.65) years. The fact of foreign body swallowing was revealed in anamnesis of 46 (60.5%) patients. Mental illnesses were diagnosed in 4 children — 5.3%, which is higher than the average incidence in pediatric population. Clinical symptoms were registered in 4 (11.8%) children with a single magnet foreign body and in 33 (78.6%) children with multiple ones. The basic diagnostic technique was an overview radiography of the abdominal cavity (70 cases, 92%), which allowed to identify both a foreign body and complications (signs of intestinal obstruction, free gas in the abdominal cavity). Esophagogastroduodenoscopy was performed in 50 cases (65.8%), out of which one foreign body was detected in 34 (68%) cases, and in 28 patients, foreign bodies were removed. Other diagnostic methods (ultrasound, spiral computed tomography) were used much less frequently. Among curative techniques, open surgeries prevailed — 32 cases (42%). Laparoscopy was used in few cases. CONCLUSION: The timely diagnostics of magnetic foreign bodies in gastrointestinal tract often depends on anamnesis findings, and if there is no such, diagnostics most often is delayed and is made only intraoperatively. Among the diagnostic techniques, it is difficult to identify a universal one that can be recommended as the "gold standard"; however, the most widely used and well-informative is abdominal X-ray and esophagogastroduodenoscopy. As to surgical tactics, the role of laparoscopic interventions is relatively low. Most often, endoscopy or "open" surgery are performed.

Inequities in Inpatient Pediatric Patient Safety Events by Category.

Few studies have analyzed potential inequities in both pediatric patient safety events (PSEs) and adverse events (AEs) - PSEs leading to harm - nor in PSEs by event type. We sought to examine potential inequities in rates of pediatric PSEs overall, by severity, and by category based on race and ethnicity, insurance payor, and language as measured using voluntary incident reports (IRs). We conducted a retrospective cohort study of pediatric hospitalizations between January 19, 2012 through December 31, 2019 at a US urban, tertiary care children's hospital. Analyzing 85 458 hospitalizations, we compared PSEs overall, by severity, and by event category by race and ethnicity, insurance payor, and language using incident rate ratios (IRRs). In models controlling for covariates, we found that hospitalizations of Latinx (IRR 1.17, 95% confidence interval [CI] 1.07-1.29), non-Latinx Black/African American (IRR 1.17, 95% CI 1.01-1.34), publicly insured (IRR 1.10, 95% CI 1.02-1.20), and nonprivately/nonpublicly insured (IRR 1.12, 95% CI 1.02-1.23) children had higher rates of PSEs compared with reference groups, but the association between language and PSEs was not significant. There were similar patterns among AEs, although only the association between hospitalizations of Latinx patients and AEs was significant. Medication, fluid, or blood and lines or tubes PSEs drove many inequities. We found inequities in PSEs as recorded by IRs, suggesting differences in care related to race, ethnicity, and payor. Limitations include analysis of a single center, that event categories are unique to the institution analyzed, and the voluntary nature of IRs.

The Effect of Emotional Coworker Support on Work Engagement Among Pediatric Health Care Providers: The Mediator Role of Emotional Regulation.

Previous findings demonstrated that healthcare workers with a high level of social support are likely to engage in their work. Healthcare workers are not only engaged in the physical problems of their patients but also in their emotional difficulties. Pediatric professionals must express and regulate their own emotions during their interactions with young patients and their families. The purpose of this study was to explore the impact of coworkers' emotional support on healthcare workers' work engagement in pediatric healthcare settings and the emotional regulation mechanisms by which emotional coworker support leads to work engagement. A cross-sectional study was distributed in a Belgian pediatric hospital between October 2021 and December 2021. The sample consisted of 274 healthcare workers who were in direct contact with patients. Participants completed a questionnaire consisting of measures of coworker emotional support, work engagement, emotional suppression, and cognitive reevaluation. Emotional suppression partially mediated the effects of perceived emotional coworker support on work engagement. Coworkers' emotional support fosters work engagement by reducing the negative effects of emotional suppression. Moreover, cognitive evaluation was positively associated with work engagement. These results provide insight into the influence of perceived emotional coworkers, emotional suppression, and cognitive reevaluation on work engagement.

Desmoplakin Cardiomyopathy in Pediatric Patients: A Distinct, Underrecognized Cohort of Arrhythmogenic Cardiomyopathy.

DSP cardiomyopathy is a distinct subset of arrhythmogenic cardiomyopathy, reported primarily in adults, that has predominantly left ventricular involvement and features of myocarditis. Clinical characteristics, risk stratification, and management of pediatric patients with DSP variants are not well known. We sought to identify phenotypic features and prognosis of pediatric patients with DSP pathogenic or likely pathogenic variants. Multicenter, retrospective study of patients <21 years of age with DSP variants from 6 tertiary pediatric hospitals. Thirty-four patients, including 10 probands with clinical disease and 24 genotype-positive phenotype-negative patients, were included in the study. The majority of probands were initially diagnosed with myocarditis (50%) and had biventricular (60%) or left ventricular predominant (40%) disease. Chest pain was the most common symptom at presentation (30%), and all had troponin elevation. Probands with homozygous or compound heterozygous DSP variants were likely to present at an early age (<13 years) with symptoms of heart failure, severe biventricular involvement, and dermatologic abnormalities. Low-voltage QRS was the most prominent ECG abnormality. Of those who underwent implantable cardioverter defibrillator implantation, 50% received appropriate implantable cardioverter defibrillator therapy and were found to have significant biventricular involvement in addition to severe left ventricular dysfunction with an ejection fraction <35%. DSP cardiomyopathy in children and adolescents has varied phenotypic manifestations based on age and genotype and often can be diagnosed as myocarditis. Severe left ventricular dysfunction and biventricular involvement may be associated with a higher likelihood of malignant ventricular tachyarrhythmia.

The Study of Lung Ultrasound, Chest CT and Chest X-ray in Children with COVID-19 Hospitalized in Mofid Children's Hospital During a Six-Month Period

Background: Coronavirus disease (COVID-19) is caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). The primary diagnostic tool for pediatric COVID-19 patients is polymerase chain reaction (PCR). Chest imaging findings in pediatric COVID-19 cases are often normal or mild. The correlation of lung ultrasound (LUS) with chest computed tomography (CT) and chest X-ray (CXR) in pediatric COVID-19 patients has not been extensively studied. Objectives: This study aimed to assess the correlation of LUS with chest CT and CXR in detecting COVID-19 pneumonia in children. Methods: This single-center cross-sectional study included patients under 18 years of age diagnosed with COVID-19 by PCR or by abnormal chest CT findings suggestive of COVID-19, admitted to Mofid Pediatric Hospital between December 2021 and August 2022. All patients underwent LUS. Approximately half of the patients also had a chest CT, and CXR was performed on 35 patients. Lung ultrasound and CT scores were calculated, and the correlation between these scores was evaluated. The correlation between LUS and CXR was also analyzed. Results: Sixty patients were included, of whom 21 were female, with a mean age of 4.9 ± 4.0 years. A significant correlation was observed between LUS and CT scores (correlation coefficient = 0.467, P = 0.011). Lesion distribution was similar between LUS and CT. However, no significant correlation was found between LUS scores and CXR findings (P = 0.392). Sixteen out of 19 patients with normal CXRs had LUS scores ≤ 4. Notably, three patients with normal CXRs had LUS scores of 8, 14, and 14. Conclusions: Lung ultrasound was more sensitive than CXR and demonstrated a significant correlation with CT. Lung ultrasound may serve as a safe alternative to CT for detecting COVID-19 pneumonia in pediatric patients.

Hypoglossal Nerve Stimulation Outcomes in Pediatric Trisomy 21 Patients with Overweight or Obesity.

To assess the impact of body mass index (BMI) on hypoglossal nerve stimulator (HNS) implantation outcomes in pediatric patients with Down syndrome (DS). We compare outcomes of HNS implantation when comparing children based on overweight or obese status. Retrospective cohort study of patients at a single tertiary pediatric hospital who underwent HNS implantation between 2022 and 2024. Patients with DS under 21 years of age at time of implantation were included. One child with Wolf-Hirschhorn syndrome was also included. The main outcome measured was reduction in apnea-hypopnea index (AHI). Twenty patients were implanted with HNS during the study period. Eleven patients were implanted with a BMI considered overweight and 8 patients with a BMI considered obese. No significant correlation was found between BMI percentile and AHI reduction (r = 0.06, p = 0.8). No significant differences were found between obese and non-obese groups for preoperative AHI, postoperative AHI, or AHI reduction. Both groups responded favorably to HNS therapy with AHI reduction of 83.8% in obese patients and 81.9% in non-obese patients. We demonstrate no difference in postoperative AHI outcomes when comparing patients with obesity defined as BMI >95th percentile compared to those without. 3 Laryngoscope, 2024.

RNA-First Approach Identifies Deep Intronic PHEX Variants in X-Linked Hypophosphatemic Rickets.

Up to 20% of patients with X-linked hypophosphatemic rickets (XLH) have no causative variant identified on routine molecular diagnostic testing. To identify intronic variants causing PHEX mis-splicing in patients with XLH. The metabolic bone clinic of a paediatric orthopedic hospital. Four patients (age 6 to 12 years; 3 girls) with clinically diagnosed XLH and no PHEX variant on routine testing. RNA and DNA sequence analysis of PHEX. Urine-derived cells were cultured, and mRNA was extracted and transcribed to cDNA. PHEX cDNA was amplified by PCR, followed by sequencing of PCR products. Sequencing of PHEX intronic DNA regions was performed to identify variants causing mis-splicing observed on RNA analysis. PHEX mis-splicing was identified in 3 of the 4 participants, and an intronic variant was identified in all 3 cases. In a 12-year-old boy, transcript analysis showed skipping of PHEX exon 13, while sequencing of PHEX intronic regions revealed a de novo 18 bp deletion in intron 13. In a 7-year-old girl, a pseudoexon in PHEX intron 17 was found, associated with a de novo deep intronic variant (c.1768+173A>G) that activated a cryptic splice donor site. Finally, an 84 bp pseudoexon in PHEX intron 21 caused by a recurrent de novo deep intronic variant (c.2147+1197A>G) was identified in an 11-year-old girl. Analysis of RNA from urine-derived cells combined with sequencing of PHEX introns can identify deep intronic variants in individuals with XLH without a detectable PHEX variant in routine exon-centric molecular diagnosis.

The Oswestry Disability Index is not a good measure for low back pain in adolescents: A Rasch analysis of data from 200 people.

To evaluate the psychometric properties of the modified Oswestry Disability Index in adolescents with low back pain through Rasch analysis. This is a psychometric study. Physical therapy clinics of a large pediatric hospital in Columbus, Ohio (United States). Two hundred adolescent patients with low back pain (112 female, 15.4 ± 1.9 years old). The modified Oswestry Disability Index. The mean modified Oswestry Disability Index score was 17.1 ± 12.1, with scores ranging from 0 to 56 on the 100-point scale. The Rasch person reliability for the Oswestry Disability Index was 0.70, representing minimal acceptable person reliability. The Oswestry Disability Index demonstrated poor item spacing, hierarchy, and targeting of the adolescents' disability level (>1 logit between person mean and item mean). A significant misfit was observed in three of 10 items. There were significant issues with the functioning of responses on all items of the Oswestry Disability Index. Principal component analysis of residuals revealed a ratio of 5.3:1, demonstrating acceptable unidimensionality. Due to multiple psychometric issues, the Oswestry Disability should not be used to assess disability in adolescents with low back pain. The Oswestry Disability Index significantly mistargets adolescent ability and only provides an acceptable assessment of the most disabled adolescents.

Economic Evaluations of Health Care Interventions in Pediatric Hospital Care.

The hospital medicine movement thrives in a health care environment committed to providing high-quality, safe, and value-based care. Hospitalists and hospitals continually grapple with many decisions regarding adopting new interventions and deadopting established ones. These decisions span the gamut from tests, treatments, and supportive care, to care models. Traditionally, the choice to adopt one intervention over another is commonly thought of in terms of its direct impact on patient outcomes, benefits, and harms. However, the evolving landscape of health care, characterized by increasing constraints on resources necessitates a broader perspective, one that includes a thorough consideration of the economic implications. The goal is not to minimize costs but rather to maximize value, outcomes achieved for money spent. Economic evaluations of health care interventions can provide this information by quantifying value and assisting health care providers, hospitals, and health systems in deciding which intervention to adopt. Economic evaluations deal with both inputs (ie, costs) and outputs (ie, consequences). Few economic evaluations in pediatric hospital medicine have been published, and many clinicians are unfamiliar with them. This paper discusses the economic evaluation of health care interventions with special attention to the pediatric hospitalist and hospital care. The paper aims to give readers an understanding of the key concepts underlying economic evaluations.

Identification of atypical pediatric diabetes mellitus cases using electronic medical records

IntroductionThere are no established methods to identify children with atypical diabetes for further study. We aimed to develop strategies to systematically ascertain cases of atypical pediatric diabetes using electronic medical...
