Does surgical sequencing influence the accuracy of maxillary positioning in bimaxillary cleft orthognathic surgery?

To evaluate whether the sequence of osteotomies influences the accuracy of maxillary positioning in patients with cleft palate ± cleft lip undergoing bimaxillary orthognathic surgery (OGS). This was a prospective study of patients with Veau 2-4 clefts who underwent bimaxillary OGS at tertiary-care children's hospital over a 3-year period. The primary predictor variable was the sequence of osteotomies (maxilla-first versus mandible-first). The primary outcome of interest was the concordance between the planned and achieved maxillary position, as assessed using linear and angular measurements. Secondary study predictors were demographic and surgical variables. Differences between groups were compared using non-parametric independent samples tests for continuous measures (data reported as median and interquartile range, IQR) and chi-squared tests for categorical measures. For all analyses, p≤ 0.05 was considered significant. Subjects who underwent maxilla-first (n=15) and mandible-first (n=16) operations were comparable with regard to age, gender, cleft type, skeletal classification, segmental maxillary osteotomy, and magnitude of maxillary movement (p ≥ 0.09). The planned sagittal and vertical positions of the maxilla were similarly accurate between the two groups (p ≥ 0.68). Angular accuracy was also comparable (p ≥ 0.56) between the study groups. In patients with CP ± CL undergoing bimaxillary orthognathic surgery, use of mandible-first sequencing, when compared to maxilla-first sequencing, does not impact accuracy of maxillary positioning in the immediate post-operative period in well-selected patients.

Is Routine Pathology Evaluation of Tissue Removed for Fertility Preservation Necessary?

BackgroundFor all fertility preservation (FP) cases at our institution, a biopsy is performed for routine pathology from all gonadal tissue removed. This is not standard at all centers. We reviewed our experience with biopsy for pathological evaluation of ovarian and testicular specimens in FP cases to determine clinical utility. MethodsThe medical records of individuals who underwent ovarian tissue cryopreservation (OTC) or testicular tissue cryopreservation (TTC) between 2011 and 2023 were retrospectively reviewed under an IRB-approved study at a free-standing tertiary care children's hospital. Patient demographics, diagnosis, operative characteristics, and pathology results were collected. ResultsOne-hundred and eighty-three patients underwent OTC, and 134 patients underwent TTC. All patients had their gonadal tissue biopsied for routine pathology. Malignancy was identified in the biopsies of 4 OTC patients (2.2%) and 2 TTC patients (1.5%). Two OTC patients (1.1%) and 2 TTC patients (1.5%) did not have germ cells identified in their biopsy. All OTC and TTC patients and families elected to continue storing tissue for FP after discussion of pathology findings. ConclusionsPathology results provide another data point to help inform patients and their families when making decisions on ovarian or testicular tissue storage and on how tissue may be utilized in the future to restore fertility and/or hormones. There is a low rate of identifying malignancy in gonadal tissue biopsies taken from FP specimens even in patients with known malignancy. However, when malignancy was identified, it could be unexpected and alter the diagnosis and treatment plan significantly for patients. Level of EvidenceIV.

Prospective evaluation of nasal septal perforation repair with absorbable plate and temporalis fascia in early adolescent patients

ObjectivesIn the pediatric population, nasal septal perforations (NSP) are rare, and management is not well described. The use of various techniques has been reported in adults, including the use of interposition grafts, however this technique has not been described in the pediatric population.Our hypothesis is that the closure rate using absorbable d-lactide and l-lactide (each 50 %), polymer (PDLLA) plates as interposition grafts with temporalis fascia for NSP repair in the pediatric population will be an effective method compared to previous techniques. MethodsChart review was performed on patients who underwent NSP repair before June 2021, results were compared to a prospective evaluation of an interposition plate graft for repair at a tertiary care children's hospital. ResultsFifteen patients via previous techniques and 5 patients via PDLLA and fascia graft were reviewed. Etiology of perforations included 45 % idiopathic, 25 % traumatic, and 15 % iatrogenic. In the previous techniques group, 10 were male, mean (median) age 14.4 years (15.2). Average size of NSP was 12.6 mm ± 6.6 mm (SD). 14/15 (93 %) patients had resolution of symptoms at 10-week follow-up, and 2/15 (13 %) required repeat repair. Five prospective patients were repaired with a PDLLA and fascia interposition graft, 4 were female, mean (median) age 14.6 years (Nassif and Scott, 2021 Feb 1) [14]. Average size of NSP was 11 mm ± 2.2 mm (SD). 100 % had resolution of symptoms at 10-week follow-up, 0 needed repeat surgery. No significant difference was found in size of NSP or in need for repeat procedure (p > 0.05) between the groups. ConclusionUse of absorbable PDLLA interposition grafts with temporalis fascia for NSP repair in the pediatric population is effective at closing and resolving symptoms associated with NSP.

Improved outcomes of pediatric patients with swallowing disorders through a multidisciplinary dysphagia clinic in a tertiary care children's hospital in Colombia

AbstractMultidisciplinary clinics bring together multiple specialists to care for patients with complex diseases, such as swallowing disorders. Little information exists regarding dysphagia in pediatric patients and its multidisciplinary management in Colombia. This study aimed to characterize patients under the age of 18 with swallowing disorders treated in a multidisciplinary dysphagia clinic at San Vicente Fundacion Hospital in Medellin, Colombia, between 2014 and 2021. A longitudinal, descriptive, observational study with retrospective data collection was conducted. Sociodemographic and clinical data were obtained at three points. A total of 293 patients were included. The most frequent underlying diseases were neurological (mainly cerebral palsy), followed by genetic disorders, with Down syndrome being the most representative. More than 50% of the patients had been hospitalized at least twice for dysphagia. The diagnosis was primarily clinical, supported by a videofluoroscopic swallowing study. The primary prescribed intervention was speech therapy, followed by an alternate feeding route. This study described pediatric patients with swallowing disorders seen in a multidisciplinary clinic. This overview provides healthcare personnel with an understanding of the complexity of swallowing disorders and their relationships to various medical conditions in children.

True Rate of Allergy among Pediatric Inpatients with Penicillin Allergy Labels (TRIAL).

Penicillin allergy is a common drug allergy diagnosis in pediatric patients; however, upon appropriate allergy testing, many of these patients are found not to have a true allergy. For patients with a reported allergy, alternative antibiotics are prescribed, which are less effective, more toxic, or more expensive. There is a lack of data evaluating allergies in hospitalized children and comparing allergy assessments conducted by pediatric allergists and pharmacists. To estimate the percentage of pediatric patients admitted with reported penicillin allergy who did not have a true penicillin allergy. This single-centre prospective cohort study included inpatients between 6 months and 17 years of age, with a documented penicillin allergy, who were admitted to the general pediatric and oncology units of a tertiary care children's hospital between November 2019 and March 2023. The allergy history, evaluation, and risk categorization were performed by pharmacists. The history was reviewed with the allergist, and the patient was then referred, underwent skin testing, or received oral amoxicillin challenge with monitoring for 1 hour. Thirty patients were included, of whom 29 (97%) had delabelling of their penicillin allergy. Four patients (13%) had delabelling on the basis of history alone, without risk assessment. Twenty-five (83%) of the patients were assessed as having low risk; 24 of these had delabelling following oral challenge, and 1 did not complete the oral challenge because of transfer to another hospital. One patient (3%) was assessed as having moderate risk, with delabelling on the basis of results of skin testing and oral challenge. The pharmacist's and allergist's risk assessments were in agreement in 29 (97%) of the 30 cases. Pediatric patients, including those with oncologic malignancies, are often mislabelled as having a penicillin allergy. Pharmacists are able to accurately determine true allergy risk and delabel penicillin allergies for pediatric patients in the hospital setting.

Mental Health Diagnoses Risk Among Children and Young Adults With Cerebral Palsy, Chronic Conditions, or Typical Development

Mental health (MH) issues in children with cerebral palsy (CP) are poorly understood compared with other pediatric populations. To examine MH diagnosis code assignment among children and young adults with CP and compare with typically developing (TD) and chronic condition (CC) pediatric populations. This case-control study used International Statistical Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) codes to create a CP case set and CC and TD control sets using electronic health record data of children and young adults from a large tertiary care children's hospital in the midwestern United States between 2010 and 2022. Case-control matching was performed to control for demographic factors. Data were analyzed from June to December 2023. All MH diagnosis codes were mapped to ICD-10-CM and categorized using Clinical Classifications Software Refined (CCSR). The incidence rates of MH CCSR categories were calculated. Descriptive and comparative statistics were used to evaluate the significance and odds associated with factors. Data from 216 794 individuals (mean [SD] baseline age, 4.3 [5.1] years; 118 562 [55%] male) were analyzed, including 3544 individuals with CP, 142 160 individuals with CC, and 71 080 TD individuals. The CP cohort spread across Gross Motor Function Classification System (GMFCS) levels I (981 individuals [28%]), II (645 individuals [18%]), III (346 individuals [10%]), IV (502 individuals [14%]), and V (618 individuals [17%]). Rates varied significantly for anxiety (824 individuals with CP [23%]; 25 877 individuals with CC [9%]; 6274 individuals with TD [18%]), attention-deficit/hyperactivity disorder (534 individuals with CP [15%]; 22 426 individuals with CC [9%]; 6311 individuals with TD [16%]); conduct or impulse disorder (504 individuals with CP [14%]; 13 209 individuals with CC [5%]; 3715 individuals with TD [9%]), trauma or stress disorders (343 individuals with CP [10%]; 18 229 individuals with CC [8%]; 5329 individuals with TD [13%]), obsessive-compulsive disorder (251 individuals with CP [7%]; 3795 individuals with CC [1%]; 659 individuals with TD [3%]), depression (108 individuals with CP [3%]; 12 224 individuals with CC [5%]; 4007 individuals with TD [9%]), mood disorders (74 individuals with CP [2%]; 4355 individuals with CC [2%]; 1181 individuals with TD [3%]), and suicidal ideation (72 individuals with CP [2%]; 7422 individuals with CC [5%]; 3513 individuals with TD [5%]). There was significant variation in odds of MH diagnoses by GMFCS level (I-II vs III-V: odds ratio [OR], 1.23; 95% CI, 1.09-1.40; P = .001). Among individuals with CP, males were more likely than females to have diagnosis codes for conduct or impulse disorders (OR, 1.41; 95% CI, 1.16-1.73) and attention-deficit/hyperactivity disorder (OR, 1.41 [95% CI, 1.15-1.73]). Black individuals, compared with White individuals, were more likely to have diagnoses for obsessive-compulsive disorder (OR, 1.57 [95% CI, 1.14-2.16]), other mood disorders (OR, 1.85 [95% CI, 1.01-3.38]), and trauma or stress disorders (OR, 1.94 [95% CI, 1.44-2.63]). Odds for trauma or stress disorders were elevated for individuals who identified as other races compared with White individuals (OR, 2.80 [95% CI, 2.03-3.87]). In this case-control study of children and young adults with CP and matched comparisons, anxiety and conduct or impulse diagnoses were higher in individuals with CP. The lower diagnosis rates of depression and suicidal ideation may indicate underdiagnosis among individuals with CP. There is likely a need for assessment tools that are more suitable for children with CP.

Comparing Outcomes Between Standard Mepilex and Mepilex Silver for Tracheotomy Dressings.

The purpose of the study is to compare the incidence of early postoperative tracheotomy stoma wound complications in pediatric patients using a silver-impregnated barrier dressing (Mepilex Ag) versus a standard absorbent foam dressing (standard Mepilex). This is a prospective, non-blinded, randomized trial of pediatric patients undergoing tracheotomy at a tertiary care children's hospital. Patients were randomized to receive Mepilex Ag versus standard Mepilex tracheostoma dressings following tracheotomy. All patients received standard postoperative wound care and daily stomal examination. Wound related complications, breakdown, granulation, and infection were recorded for the first 7 days after surgery. A non-inferiority study design was used to test the hypothesis that the Mepilex group had a non-inferior wound complication rate (within 10% margin) compared to the Mepilex Ag group. Eighty-two patients were enrolled; 52 received Mepilex Ag, and 30 received standard Mepilex. There was no difference between the groups with respect to age, sex, race, surgical indication, or postoperative length of stay. Non-inferiority testing demonstrated that the Mepilex standard cohort had no more than 10% greater stomal wound complication rate than that of Mepilex Ag dressing group (p = 0.0108). Standard Mepilex was found to be non-inferior to Mepilex Ag in the prevention of tracheotomy stomal wound complications. Standard Mepilex may be used effectively in the postoperative period, potentially reducing costs to caregivers and the institution. Further work is needed to analyze additional factors that could contribute to poor postoperative stoma healing such as bacterial colonization.

Patient Characteristics and Postoperative Outcomes of Surgically Treated Inferior Pole Patellar Sleeve Fractures.

Despite representing over half of all pediatric patella fractures, inferior pole patellar sleeve fractures (PSFs) are a relatively uncommon pediatric injury. As a result, existing literature on PSFs is limited to case reports and small case series. The purpose of this study was to evaluate the radiographic and clinical characteristics of operatively treated PSFs as well as outcomes following surgical management. A retrospective review of all inferior pole PSFs requiring surgery from 2007 to 2023 was performed at a single urban tertiary care children's hospital. Cases were identified using diagnostic and billing codes. Patient demographics, injury characteristics, surgical techniques, and postoperative rehabilitation practices were recorded. Regional skeletal maturity, fracture characteristics, and postreduction patellar height were recorded. Postoperative complications were recorded and categorized using the modified Clavien-Dindo Classification System (CDS). Thirty-eight inferior pole PSFs were identified meeting study criteria. The majority of patients were male (86.8%), and the mean age at injury was 11.0 years (range: 7.2 to 15.0). Mean BMI was 21.1. Radiographically, the majority of patients were Epiphyseal Fusion Stage 0 (nonunion), with a median postreduction Caton-Deschamps index (CDI) of 1.2 (IQR: 1.1 to 1.3). These fractures were predominantly treated with suture-based fixation (84%). Postoperative immobilization varied within the cohort, and the initiation of knee ROM was permitted at a median of 3.5 (IQR: 2.0 to 4.6) weeks. All patients regained full range of motion and straight leg raise without extensor lag, and return-to-sport was achieved by a median of 17.6 weeks (IQR: 12.8 to 30.3). Complications occurred in 10 (26.3%) patients, with 3 (7.9%) requiring a return to the OR (CDS Grade III). Inferior pole PSFs appear to occur most commonly among prepubertal males of normal BMI and normal patellar height. Despite variable rehabilitation protocols, operative management resulted in restoration of extensor mechanism function. Eight percent of patients experienced complications requiring unplanned surgery. This large series improves our understanding of the epidemiology, injury characteristics, and postoperative outcomes of an operatively treated cohort of a rare injury pattern. Level IV.

Impact of SARS-CoV-2 Pandemic on Emergency Hospitalizations for Acute Respiratory Infections: The Experience of a Paediatric Tertiary Care Hospital in Italy.

Acute respiratory infections (ARIs) are a major healthcare issue in children. The SARS-CoV-2 pandemic changed the epidemiology of ARIs; the aims of this study are to characterize the epidemiological trend of ARI emergency hospitalizations and virology results and to estimate the association of ARI emergency hospitalizations with respiratory viruses from January 2018 to June 2023. This study was carried out in an Italian tertiary care children's hospital (Bambino Gesù Children's Hospital). The demographic and clinical information of children who accessed the Emergency Department (ED) with ARI and were hospitalized were retrospectively extracted from the electronic health records. Multivariate linear regression model was used to compare the number of ARI hospital admissions with the reported temporal trends in viruses diagnosed from respiratory samples throughout the same time period. During the study period, there were 92,140 ED visits and 10,541 hospitalizations due to ARIs, reflecting an admission rate of 11.4%. The highest proportion of hospitalizations occurred in infants ≤ 1 year of age (n = 4840, 45.9% of total admissions), with a hospitalization rate of 22.6%. Emergency hospitalizations aligned closely with the predictions made by the multivariate regression model; peaks in hospitalizations reflected Respiratory Syncytial Virus (RSV) circulation. ARI hospital urgent admissions are a relevant component of ARI disease burden in children. RSV prevention and control are crucial to limit the risk of urgent hospitalizations due to ARIs.

Impact of Intravenous Methadone Dosing Schedule on Iatrogenic Withdrawal Syndrome in a Pediatric Intensive Care Unit.

To compare median Sophia Observation withdrawal Symptoms scale (SOS) scores between -intravenous methadone dosing scheduled every 6 hours or every 8 hours for iatrogenic withdrawal -syndrome (IWS). This single-center, retrospective chart review evaluated patients aged 4 weeks through 18 years treated with intravenous methadone for IWS. Children admitted to the pediatric intensive care unit (PICU) of a tertiary care children's hospital between August 2017 and July 2021 and treated for IWS for at least 48 hours were eligible for inclusion. Methadone dosing schedules were compared, with a primary outcome of median Sophia Observation withdrawal Symptoms (SOS) score during the first 24 hours after cessation of continuous fentanyl infusion. Secondary outcomes included PICU and general pediatric unit lengths of stay, extubation failure rates, and mortality. Twenty patients met inclusion criteria, with 9 in the 6-hour dosing group. There was no difference in median SOS score, extubation failure, length of stay, or mortality between the 2 groups. During the first 24 hours after cessation of continuous fentanyl, there appears to be no -difference in IWS severity, as determined by bedside nurse scoring, between patients treated with -intravenous methadone every 6 hours compared with every 8 hours.

Implementing Inpatient Social Needs Screening in an Urban Tertiary Care Children's Hospital.

The American Academy of Pediatrics recommends screening for unmet social needs, and the literature on inpatient screening implementation is growing. Our aim was to use quality improvement methods to implement standardized social needs screening in hospitalized pediatric patients. We implemented inpatient social needs screening using the Model for Improvement. An interprofessional team trialed interventions in a cyclical manner using plan-do-study-act cycles. Interventions included a structured screening questionnaire, standardized screening and referrals workflows, electronic health record (EHR) modifications, and house staff education, deliberate practice, and feedback. The primary outcome measure was the percentage of discharged patients screened for social needs. Screening for social needs was defined as a completed EHR screening questionnaire or a full social work evaluation. Process and balancing measures were collected to capture data on screening questionnaire completion and social work consultations. Data were plotted on statistical process control charts and analyzed for special cause variation. The mean monthly percentage of patients screened for social needs improved from 20% at baseline to 51% during the intervention period. Special cause variation was observed for the percentage of patients with completed social needs screening, EHR-documented screening questionnaires, and social work consults. Social needs screening during pediatric hospitalization can be implemented by using quality improvement methods. The next steps should be focused on sustainability and the spread of screening. Interventions with greater involvement of interdisciplinary health care team members will foster process sustainability and allow for the spread of screening interventions to the wider hospitalized pediatric population.

Risk factors and outcome of antenatally diagnosed congenital diaphragmatic hernia following in-utero transfer in a busy public-sector tertiary care center in North India.

We analyzed the risk factors and outcomes of antenatally diagnosed congenital diaphragmatic hernia (CDH) from a tertiary-care children's hospital following in-utero transfer. A total of 41 antenatally detected cases of CDH were included; 30 were live-born and 11 were still-born. The primary outcome was postnatal survival. The secondary outcome was the probable factor affecting survival. No medical termination of the pregnancy was done. The mean gestational age at diagnosis was 23 weeks. The diagnostic accuracy of antenatal ultrasonography was 40/41 (97.5%). Lung-to-head ratio (LHR) was <1 in 20 cases (survived 2), LHR was >1 in 10 cases (survived 8), and LHR was not recorded in 11 cases (survived 4). Overall survival was 14/41 (34.1%). Survival in fetuses with polyhydramnios was 0% (n=3; survived 0), associated anomalies were 33.3% (n=3; survived 1), and liver herniation was 22.2% (n=9; survived 2). Postnatally, significant risk factors included a low Apgar score, the need for ventilation, and neonatal intensive care unit (NICU) management. Survival in live-born cases was 14/30 (46.6%) and in operated cases was 14/19 (73.6%). We concluded that antenatal ultrasound had a high accuracy rate for detecting CDH. Antenatal risk factors affecting outcomes were low LHR, maternal polyhydramnios, liver herniation, and associated malformations. Postnatal risk factors included a low Apgar score, NICU admission, and a need for ventilation. The overall survival rate, as well as the survival rates for live-borns and those undergoing surgery, were 34.1%, 46.6%, and 73.6%, respectively. This data will guide clinicians in counseling the families of antenatally diagnosed CDH.

Resource Utilization and Risk Factors for Esophageal Injury in Pediatric Esophageal Foreign Bodies.

While management protocols of pediatric esophageal foreign bodies (EFBs) are well-delineated, resource utilization can be improved. This study's objectives were to explore hospital charges/costs for pediatric patients who present with EFBs and to identify patient risk factors associated with esophageal injury. A retrospective chart review of patients undergoing aerodigestive foreign body removal at a tertiary-care children's hospital from 2018 to 2021 was conducted. Data collected included demographics, medical history, presenting symptoms, EFB type, surgical findings, and hospital visit charges/costs. 203 patients were included. 178 of 203 (87.7%) patients were admitted prior to operation. Unwitnessed EFB ingestion (p < 0.001, OR = 15.1, 95% CI = 5.88-38.6), experiencing symptoms for longer than a week (p < 0.001, OR = 11.4, 95% CI = 3.66-38.6) and the following presenting symptoms increased the odds of esophageal injury: dysphagia (p = 0.04, OR = 2.45, 95% CI = 1.02-5.85), respiratory distress (p = 0.005, OR = 15.5, 95% CI = 2.09-181), coughing (p < 0.001, OR = 10.1, 95% CI = 3.73-28.2), decreased oral intake (p = 0.001, OR = 6.60, 95% CI = 2.49-17.7), fever (p = 0.001, OR = 5.52, 95% CI = 1.46-19.6), and congestion (p = 0.001, OR = 8.15, 95% CI = 2.42-27.3). None of the 51 asymptomatic patients had esophageal injury. The median total charges during the encounter was $20,808 (interquartile range: $18,636-$24,252), with operating room (OR) (median: $5,396; 28.2%) and inpatient admission (median: $5,520; 26.0%) contributing the greatest percentage. Asymptomatic patients with EFBs did not experience esophageal injury. The OR and inpatient observation accounted for the greatest percentage of the hospital charges. These results support developing a potential algorithm to triage asymptomatic patients to be managed on a same-day outpatient basis to improve the value of care. 3 Laryngoscope, 134:4774-4782, 2024.

Effect of Low-dose Ketamine Infusion on Opioid Consumption in Children Undergoing Open Cardiac Surgery: A Randomized Controlled Double-Blind Study

This study was designed to evaluate the effect of low-dose ketamine infusion on the perioperative consumption of opioids in pediatric open cardiac surgery. A randomized, controlled, double-blinded single-center study was conducted. The study took place in a tertiary care children's hospital. Patients of both sexes aged 2-12 years who underwent cardiac surgery were included. Patients in the ketamine group received a bolus of 0.3 mg/kg of ketamine before skin incision followed by continuous intraoperative infusion of 0.25 mg/kg/h and postoperative infusion of 0.1 mg/kg/h for 24 h. Patients in the control groups received volumes of normal saline either bolus or continuous infusion like that of the ketamine group. The primary outcome was the total dose of fentanyl consumed over the first 24 hours postoperatively. Secondary outcomes were intraoperative fentanyl consumption, time to extubation, modified objective pain score, and incidence of vomiting, pruritus, diplopia, or hallucinations. A total of 80 patients were recruited but the final analysis was done on 35 patients in the ketamine group and 34 in the control group. Fentanyl consumption during surgery and in the first 24 hours postoperatively was significantly lower in the ketamine than the control group. Patients in both the ketamine and control groups had similar times to extubation. Modified objective pain scores were significantly lower in the ketamine group than the control group. None of the patients in either group had diplopia or hallucinations. Low-dose ketamine infusion in children undergoing open cardiac surgery reduced intra- and postoperative opioid consumption and postoperative pain scores. Moreover, ketamine did not cause diplopia or hallucinations.

Anesthetic challenges in patients with multicompartmental lymphatic failure after Fontan palliation undergoing transcatheter thoracic duct decompression.

Lymphatic flow abnormalities are central to the development of protein losing enteropathy, plastic bronchitis, ascites and pleural effusions in patients palliated to the Fontan circulation. These complications can occur in isolation or multicompartmental (two or more). The treatment of multicompartmental lymphatic failure aims at improving thoracic duct drainage. Re-routing the innominate vein to the pulmonary venous atrium decompresses the thoracic duct, as atrial pressure is lower than systemic venous pressure in Fontan circulation. Transcatheter thoracic duct decompression is a new minimally invasive procedure that involves placing covered stents from the innominate vein to the atrium. Patients undergoing this procedure require multiple general anesthetics, presenting challenges in managing the sequelae of disordered lymphatic flow superimposed on Fontan physiology. We reviewed the first 20 patients at the Center for Lymphatic Imaging and Intervention at a tertiary care children's hospital presenting for transcatheter thoracic duct decompression between March 2018 and February 2023. The patients ranged in age from 3 to 26 years. The majority had failed prior catheter-based lymphatic intervention, including selective embolization of abnormal lympho-intestinal and lympho-bronchial connections to treat lymphatic failure in a single compartment. Fourteen had failure in three lymphatic compartments. Patients were functionally impaired (ASA 3-5) with significant comorbidities. Concurrent with thoracic duct decompression, three patients required fenestration closure for the resultant decrease in oxygen saturation. Ten patients had improvement in symptoms, seven had no changes and three have limited follow up. Five (25%) of these patients were deceased as of January 2024 due to non-lymphatic complications from Fontan failure.

Outcomes of Referrals in Pediatric Patients With Peripheral Lymphadenopathy.

Lymphadenopathy is a common reason for referral to a subspecialist, which may result in significant anxiety for parents. Understanding which patients require a subspecialty referral for lymphadenopathy is key to streamlining health care utilization for this common clinical entity. This is an IRB-approved retrospective study examining pediatric patients consecutively referred to pediatric hematology oncology, otolaryngology, or surgery for lymphadenopathy from 2012 to 2021 at a free-standing tertiary-care children's hospital. Logistic regression was fitted to examine the association between the maximum size of the lymph nodes (LN) and a diagnosis of malignancy. The odds ratio, area under the receiver operator curve, sensitivity, and specificity were estimated. We found a significant association between LN size and cancer diagnosis. For every centimeter increase in the maximal dimension of LN, there was an estimated 2.3 times increase in the odds of malignancy (OR=2.3, 95% CI: 1.65-3.11; P <0.0001). The estimated area under the curve (0.84, 95% CI: 0.78-0.90) indicated that LN size correlated well with cancer diagnosis. A LN cut-off size of 2cm resulted in an estimated sensitivity of 1.0 (95% CI: 0.87-1.00) and specificity of 0.54 (95% CI: 0.46-0.61). Maximum LN size may be a predictor of malignancy among pediatric patients with lymphadenopathy.

Impact of various anesthetic regimens on motor-evoked potentials in infants undergoing spinal surgery: A case series.

Motor-evoked potential (MEP) monitoring is commonly used in children. MEP monitoring in infants is difficult due to smaller signals requiring higher stimulation voltages. There is limited information on the effect of different anesthetics on MEP monitoring in this age group. This case series describes the effect of different anesthetic regimens on MEP monitoring in infants. Patients <1 year of age who underwent spinal surgery with MEP monitoring between February 2022 and July 2023 at a single tertiary care children hospital were reviewed. The motor-evoked potential amplitudes were classified into 4 levels based on the voltage in the upper and lower limbs (none, responded, acceptable, sufficient). "Acceptable" or "sufficient" levels were defined as successful monitoring. A total of 19 infants were identified, involving 3 anesthesia regimens: 4/19 (21.1%) cases were anesthetized with propofol/remifentanil total intravenous anesthesia (TIVA), 3/19 (15.8%) with propofol/remifentanil/low-dose sevoflurane and another 12/19 (63.2%) cases who initially received propofol/remifentanil/sevoflurane and were converted to propofol/remifentanil anesthesia intraoperatively. The 4 cases with propofol/remifentanil showed 20/32 (62.5%) successful monitoring points. In contrast, 6/24 (25%) successful points were achieved with propofol/remifentanil intravenous anesthesia/0.5 age-adjusted minimum alveolar concentration sevoflurane. In 12 cases converted from propofol/remifentanil/low-dose inhalational anesthetics to TIVA alone, successful MEP monitoring points increased from 46/96 (47.9%) to 81/96 (84.4%). Adding low-dose inhalation anesthetic to propofol-based TIVA suppresses MEP amplitudes in infants. The optimal anesthetic regimen for infants requires further investigation.

Factors contributing to telemedicine efficacy in pediatric urology

Despite swift implementation of telemedicine with the coronavirus disease 2019 pandemic, there is a paucity of research on its use for management of pediatric urology patients. Specifically, there is limited knowledge and inconsistent data on the effectiveness of telemedicine for various pediatric urologic conditions. Our aim was to evaluate the efficacy of pediatric urological care provided via video visits (VVs) at a large tertiary care children's hospital. We performed a prospective assessment of pediatric urology patients younger than 21 years who had a VV between 5/18/2022 and 5/17/2023. New patients with a testicular diagnosis were not eligible for VVs. After entering the diagnosis and submitting billing using a modifier for telemedicine, clinicians were mandated to select whether the VV allowed for: complete case management (CCM), suboptimal case management (SCM), or incomplete case management (ICM) requiring an in-person visit. Case management categorizations were analyzed according to patient pathology, visit type (i.e., new or established), and patient-centered variables including age, sex, race, insurance type, need for an interpreter, and distress score [a proxy for socioeconomic status]. During the one-year period, there were 3267 telemedicine patients with a median age of 9 years (IQR 3-13) and 57.0% were male. Most VVs (89.3%) were established encounters. Almost 12% of telemedicine patients had external organ pathology (EOP, e.g., phimosis), 43.0% had internal organ pathology (IOP, e.g., hydronephrosis), and 45.1% had functional urological pathology (FUP, e.g., dysfunctional voiding). Clinicians deemed 96.9%, 2.7%, and 0.5% of VVs as having CCM, SCM or ICM, respectively. Telemedicine patients with IOP or FUP were more likely to have CCM, than those with EOP (98.5% and 97.8% vs 87.1%, p<0.0001). On multivariable analysis, patient age, pathology, and visit type were predictive of VV efficacy. Now that telemedicine use has slowed, it is necessary to evaluate and establish its optimal role in pediatric urology. Factors associated with VV efficacy included older patient age, internal organ or functional urological pathology, and established encounters. The long-term success of telemedicine requires suitable patient selection. Telemedicine is quite effective for the management of a wide variety of pediatric urology patients. Continued evaluation of telemedicine, including multi-institutional investigation and corroboration, is necessary for the development of evidence-based best practice guidelines regarding appropriate, safe, and effective integration of telemedicine that drives pediatric urological care forward to meet the demands of the future.

Pediatric hemispheric cerebellar low-grade gliomas: clinical approach, diagnosis, and management challenges-experience at a tertiary care children's hospital.

This study aims to provide an exhaustive analysis of pediatric low-grade gliomas (pLGGs) in the cerebellar hemispheres, focusing on incidence, clinical characteristics, surgical outcomes, and prognosis. It seeks to enhance understanding and management of pLGGs in the pediatric population. We conducted an observational, descriptive, retrospective, and cross-sectional study at a pediatric hospital, reviewing medical records of 30 patients with cerebellar hemispheric pLGGs treated from December 2014 to January 2023. Data collection included demographics, clinical presentation, imaging findings, surgical approach, postoperative complications, histopathological diagnosis, hydrocephalus management, and follow-up. Molecular markers and adjuvant therapies were also analyzed. The cohort predominantly presented with cerebellar symptoms, with 60% showing hydrocephalus at diagnosis. MRI with gadolinium was crucial for diagnosis. Surgical focus was on achieving gross total resection (GTR), accomplished in 70% of cases. Postsurgical hydrocephalus was less common, and cerebellar mutism was not reported. While a complete molecular analysis was not performed in all cases, available data suggest significant influence of molecular markers on prognosis and therapeutic options of pLGGs. This study highlights the unique clinical and molecular characteristics of cerebellar hemispheric pLGGs in children. The lower incidence of postoperative hydrocephalus and absence of cerebellar mutism are notable findings. Emphasizing a multidisciplinary approach, our findings contribute to a deeper understanding of pediatric pLGGs, underscoring the need for personalized treatment strategies and vigilant follow-up.
