Abstract
PURPOSE OF REVIEW Recent studies have suggested that prolonged or repeated episodes of general anesthesia early in childhood may adversely affect neurodevelopment. This, combined with rising healthcare costs and decreasing access, has sparked interest in performing pediatric procedures in the office setting when possible. It is essential to address the physical and psychological discomfort that often accompany this experience, particularly in children. RECENT FINDINGS Healthcare providers performing procedures on children can draw from a spectrum of established techniques, new technology, and novel use of medications to decrease peri-procedural pain and anxiety. These techniques include distraction, optimization of local anesthesia, and mild to moderate sedation. SUMMARY We recommend using a combination of techniques to minimize pain and anxiety to improve safety, decrease healthcare costs, improve patient experience, and prevent childhood trauma and persistent negative perception of the healthcare system.

Abstract
INTRODUCTION Firearms are the leading cause of death in the pediatric population, and the incidence of firearm injury is on the rise in the United States. The purpose of this study was to examine the incidence of pediatric gunshot wounds (GSWs) in New Orleans from 2012 to 2023 and evaluate factors that contribute to mortality. METHODS A retrospective analysis of pediatric GSWs was conducted using the trauma database at a Level I trauma center in New Orleans, Louisiana. All patients aged 0 to 18 years with a GSW between January 1, 2012, and January 1, 2023, were evaluated. Demographic data, Injury Severity Score (ISS), hospital length of stay (LOS), discharge disposition, intent of injury, mortality, firearm type, orthopaedic injuries, and related surgical procedures were extracted from the database. Linear regression was used to assess the trend of GSWs over time, and logistic regression was used to identify variables that predicted mortality. Statistical significance was defined as α = 0.05. Geographic information system (GIS) mapping was conducted using the ZIP code location of injury to identify geographic areas with the greatest number of GSWs. RESULTS A significant increasing trend was observed in the number of pediatric GSWs when adjusted for changes in population ( P = 0.014), and the number of GSWs increased 43.2% over the duration of the study. Higher ISS, shorter length of stay, and self-inflicted intent of injury were notable predictors of mortality. Three hundred fifty-four patients (31.4%) had at least one orthopaedic injury, and of the survivors, 365 patients (35.6%) required at least one surgical procedure in the operating room during their admission. DISCUSSION The number of GSWs in the pediatric population in New Orleans presenting at a large level 1 trauma center demonstrated a statistically significant increasing trend over the past 11 years. ISS and self-inflicted intent were predictive of mortality within this pediatric patient population.

Abstract
OBJECTIVES Proper electrode placement is essential for favorable hearing outcomes following cochlear implantation. Though often used, traditional intraoperative X-ray imaging is time consuming, exposes patients and staff to radiation, and poses interpretational challenges. The Nucleus® SmartNav System, utilizes electrode voltage telemetry (EVT) to analyze the positioning of the electrode array intraoperatively. This study investigates the efficacy of SmartNav in optimizing the efficiency and accuracy of assessing electrode placement. METHODS This prospective clinical study analyzed placement of 50 consecutive Cochlear Corporation cochlear implants conducted at a single institution between March of 2022 and June of 2023. Placement check of electrode array using SmartNav and X-ray was completed and individually assessed. A comparative analysis of SmartNav and X-ray completion times for electrode placement assessment was conducted. RESULTS Subjects included nine ears with abnormal anatomy and three reimplants. SmartNav placement check required a total time of 2.12 min compared to X-ray imaging at 14.23 min (p = 1.6E-16, CI 95%). Both SmartNav and X-ray had excellent sensitivity of 100% in identifying appropriate electrode position (p = 1.0). Tip fold-over was identified using both modalities in 3 cases with noted easier interpretation using SmartNav. CONCLUSION The Nucleus® SmartNav System significantly outperformed traditional X-ray imaging, offering a faster and more straightforward approach to assessing electrode positioning during cochlear implant surgery, thereby enhancing surgical efficiency and patient safety.

Abstract
Up to 75% of paediatric patients experience anxiety and distress before undergoing new medical procedures. Virtual reality is an interesting avenue for alleviating the stress and fear of paediatric patients due to its ability to completely immerse the child in the virtual world and thus expose them to the sights and sounds of an MRI before undergoing the exam. We aimed to explore the impact of virtual reality exposure on reducing fear and anxiety in paediatric patients scheduled to undergo an MRI. We hypothesised that patient who had undergone VR exposure before the MRI would experience lower levels of fear and anxiety and subsequently have a higher MRI success rate. We conducted a prospective randomized control trial in a tertiary paediatric hospital over three weeks. Inclusion criteria comprised children aged 4 to 14 undergoing MRI without medical contraindications for VR use. Thirty patients (16 in VR, 14 in control) were included in the study. The VR room, created in-house by a researcher, that the VR group experienced, simulated MRI room with typical sounds for up to 5 min before their actual MRI. Fear and anxiety were measured using the FACES scale before and after MRI for the control group as well as after VR exposure for the VR group. The VR group exhibited a significant reduction in anxiety post-VR exposure regarding the upcoming MRI (p = 0.009). There was no significant difference with regards to fear and anxiety between the VR and control groups before or after the MRI exam. There was no significant difference between the MRI exam success rates. VR exposure effectively reduces pre-MRI anxiety in paediatric patients who are about to undergo the exam, this is important as it alleviates the psychological burden on the child. This research is in line with previous findings, showing the validity of VR as a method of reducing pre-procedural paediatric anxiety and suggesting that complex VR experiences may not be necessary to have a significant impact. There is, however, a need for further investigation in this field using larger and MRI-naïve groups of patients.

Abstract
Background For children who are unable to cooperate due to severe dental anxiety (DA), dental treatment of childhood caries under Dental General Anesthesia (DGA) is a safe and high-quality treatment method. This study aims to evaluate the impact on neurocognitive functions and the growth and development of children 2 years after dental procedure based on previous research, and further establish a causal relationship between general anesthesia (GA) and changes in children's neurocognitive functions by incorporating Mendelian Randomization (MR) analysis. Methods Data were collected and analyzed from 340 cases of S-ECC procedures of preschool children conducted in 2019. This involved comparing the neurocognitive outcomes 2 years post-operation of preschool children receiving dental procedures under general anesthesia or local anesthesia. Physical development indicators such as height, weight, and body mass index (BMI) of children were also compared at baseline, half a year post-operation, and 2 years post-operation. We performed a Mendelian randomization analysis on the causal relationship between children's cognitive development and general anesthesia, drawing on a large-scale meta-analysis of GWAS for anesthesia, including multiple general anesthesia datasets. Results Outcome data were obtained for 111 children in the general anesthesia group and 121 children in the local anesthesia group. The mean FSIQ score for the general anesthesia group was 106.77 (SD 6.96), while the mean score for the local anesthesia group was 106.36 (SD 5.88). FSIQ scores were equivalent between the two groups. The incidence of malnutrition in children in the general anesthesia group was 27.93% (p < 0.001) before surgery and decreased to 15.32% (p > 0.05) after 2 years, which was not different from the general population. The IVW method suggested that the causal estimate (p = 0.99 > 0.05, OR = 1.04, 95% CI = 5.98 × 10-4-1.82 × 103) was not statistically significant for disease prevalence. This indicates no genetic cause-and-effect relationship between anesthesia and childhood intelligence. Conclusion There were no adverse outcomes in neurocognitive development in 2 years after severe early childhood caries (S-ECC) procedure under total sevoflurane-inhalation in preschool children. The malnutrition condition in children can be improved after S-ECC procedure under general anesthesia. Limited MR evidence does not support a correlation between genetic susceptibility to anesthesia and an increased risk for intelligence in children.

Abstract
The Pediatric Normal Tissue Effects in the Clinic (PENTEC) consortium has made significant contributions to understanding and mitigating the adverse effects of childhood cancer therapy. This review addresses the role of diagnostic imaging in detecting, screening, and comprehending radiation therapy-related late effects in children, drawing insights from individual organ-specific PENTEC reports. We further explore how the development of imaging biomarkers for key organ systems, alongside technical advancements and translational imaging approaches, may enhance the systematic application of imaging evaluations in childhood cancer survivors. Moreover, the review critically examines knowledge gaps and identifies technical and practical limitations of existing imaging modalities in the pediatric population. Addressing these challenges may expand access to, minimize the risk of, and optimize the real-world application of, new imaging techniques. The PENTEC team envisions this document as a roadmap for the future development of imaging strategies in childhood cancer survivors, with the overarching goal of improving long-term health outcomes and quality of life for this vulnerable population.

Can growing patients with end-stage TMJ pathology be successfully treated with alloplastic temporomandibular joint reconstruction? - A systematic review. Oral Maxillofac Surg 2024; 28:529-537. [PMID: 37733214 DOI: 10.1007/s10006-023-01180-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2023] [Accepted: 09/08/2023] [Indexed: 09/22/2023]
Abstract
INTRODUCTION The use of alloplastic total temporomandibular joint reconstruction (TMJR) in growing patients is controversial, mainly due to immature elements of the craniomaxillofacial skeleton. The aim of this systematic review was to evaluate the use of alloplastic TMJR in growing patients, focusing on the patient's clinical presentation, surgical and medical history and efficacy of alloplastic TMJR implantation. MATERIALS AND METHODS The literature search strategy was based on the Population, Intervention, Comparator, Outcomes and Study type (PICOS) framework. We searched Pubmed, Google Scholar, Dimension, Web of Science, X-mol, Semantic Scholar and Embase to January 2023, without any restriction on the type of publication reporting alloplastic TMJR in growing patients (age ≤ 18 years for boys and age ≤ 15 years for girls). RESULTS A total of 15 studies (case reports: 09, case series: 02, cohort studies: 04) met the inclusion criteria, documenting 73 patients of growing age from 07 countries. Thirty-eight (~ 52%) cases were female. The mean ± SD (range) age and follow-up of patients in all studies was 13.1 ± 3.2 (0-17) years and 34.3 ± 21.5 (7-96) months, respectively. A total of 22 (30%) patients were implanted with bilateral alloplastic TMJR. Over half of the studies (n = 10) were published in the last 3 years. All patients underwent multiple surgeries prior to implantation of alloplastic TMJR. In extreme cases, patients underwent a total of 17 surgeries. Different types of studies reporting inconsistent variables restricted our ability to perform quality assessment measures for evidence building. CONCLUSIONS Clinical experience with alloplastic TMJR in growing patients is limited to cases showing poor prognosis with other types of reconstruction. Nevertheless, studies show promising results for the use of alloplastic TMJR in growing patients, highlighting the need for well-controlled prospective studies with long-term follow-up.

Abstract
BACKGROUND In the pediatric population, virtual reality (VR) has been used as an adjunct to augment analgesia and reduce the need for opioids. In this study, we review our experience using VR in lieu of anesthesia or sedation to enable minor procedures in children. METHODS A retrospective chart review study was performed on patients who presented to our institution from 2019 to 2022 for hormone implant placement, exchange, or removal with VR distraction. Demographic and procedure information was recorded. The primary outcome was successful procedure completion without requiring pharmacologic sedation or analgesia. RESULTS A total of 111 patients underwent the following minor procedures with VR and without anesthesia or sedation. Fourteen patients had multiple encounters resulting in a total of 126 encounters. The median age was 11 [6] years. 43 patients were female, 23 were female to male, 6 were non-binary, 7 were male, and 32 were male to female. 58 % had private insurance. Most common diagnosis was precocious puberty (54 %) followed by gender dysphoria (46 %). Most common procedure was implant placement (72 %). 69 % of procedures were performed in the clinic and 31 % in the OR. All procedures were completed without requiring the administration of additional sedation or anesthesia. None of the patients required intravenous catheter placement for the procedure. No intra-procedural complications were recorded. CONCLUSION VR is a feasible option that can spare children from sedation or general anesthesia for minor procedures. VR may enable minor procedures in children to be successfully performed in clinic setting. LEVEL OF EVIDENCE: 4

Abstract
Purpose Pediatric low-grade tectal gliomas are rare, indolent tumors of the brain stem. We reviewed outcomes of pediatric patients who received a diagnosis of low-grade tectal gliomas and report dosimetric parameters for those receiving radiation therapy (RT). Methods and Materials We retrospectively reviewed all pediatric patients (age <18 years) at our institution diagnosed with a low-grade glioma between 1993 and 2020 (n = 288). Twenty-three patients with tectal gliomas were identified. Patients who received RT (n = 8) had detailed dosimetric analyses performed. Doses to critical structures and any resulting toxicities were reviewed. Minimum follow-up was 2 years and complete follow-up was available for all patients. Results Twenty-three patients, with a median age of 8.9 years, were included (range, 0.5-16.2 years). At a median follow-up of 7.4 years (range, 2-24 years), all were alive at the end of the study period. Three patients (13%) were treated with upfront RT; none of these patients developed local failure (LF) after a median follow-up of 10.6 years. One patient was treated with upfront chemotherapy with no evidence of progression afterward. Nineteen patients were initially observed after diagnosis and 26% of them (n = 5) experienced local progression. All 5 were treated with salvage RT, with 1 patient requiring further treatment with chemotherapy. Fractionation schedules for patients undergoing upfront or salvage RT included 50.4 Gy in 28 fractions (n = 4), 54 Gy in 30 fractions (n = 2), and 51 Gy in 30 fractions (n = 2). For patients treated after 2007, the gross tumor volume was delineated on a T2 magnetic resonance imaging with an average gross tumor volume-to-planning target volume expansion of 4.5 mm (range, 3-5 mm). Detailed dosimetric parameters were available for all patients treated with RT. Conclusions Our review supports the indolent behavior for most tectal gliomas. For the subset of tumors with evidence of progression, modern photon RT results in excellent oncologic outcomes with minimal late effects.

Brain Res Bull 2023; 204:110809. [PMID: 37931809 DOI: 10.1016/j.brainresbull.2023.110809] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2023] [Revised: 10/27/2023] [Accepted: 11/03/2023] [Indexed: 11/08/2023]
Abstract
BACKGROUND Sevoflurane, a commonly administered inhaled anesthetic, is found to induce synaptic and mitochondrial damage in neonatal mice. Mitochondrial membrane potential (MMP) changes, mediated by Cyclophilin D (CypD), are implicated in mitochondrial function. Melatonin, known for its significant neuroprotective properties, was investigated in this study to elucidate its mechanisms in mitigating the cognitive impairment caused by sevoflurane. METHODS The mice were categorized into several groups, including the control, vehicle, sevoflurane, vehicle plus sevoflurane, and melatonin plus sevoflurane groups. From postnatal day 6 to day 8, the mice were administered inhaled sevoflurane or intraperitoneal melatonin. MMP and reactive oxygen species (ROS) were measured using appropriate detection kits. The protein expression levels of PSD95, Synapsin Ⅰ, and CypD in the hippocampus were analyzed through western blotting in acute and prolonged terms. Immunofluorescence staining was used to assess the co-localizations of PSD95 or CypD in parvalbumin (PV) neurons. Cognitive ability was evaluated through novel object recognition, social interaction experiment, and the Morris water maze. RESULTS The findings revealed that repeated exposure to sevoflurane in neonatal mice resulted in cognitive and synaptic impairment. Furthermore, melatonin administration suppressed the ROS and CypD protein expression, enhanced the MMP in mitochondria and synaptic protein expression in PV neurons, and ameliorated cognitive deficits. CONCLUSION Melatonin alleviated sevoflurane-induced cognitive deficits by suppressing CypD and promoting synaptic development in hippocampal PV neurons. These results provide valuable insights into a promising therapeutic approach for preventing neurotoxic injuries caused by general anesthetics.

Abstract
PURPOSE OF REVIEW The use of lasers in pediatric dermatology is well established, but recent literature has expanded the evidence for specific timelines of treatment. Additionally, new devices and combinations with medical therapy have improved outcomes and treatment options for various conditions. RECENT FINDINGS Pulsed dye laser remains the first-line laser for vascular lesions. Recent guidelines support early initiation of laser treatment in port-wine birthmarks to optimize outcomes. For hemangiomas, laser treatment can offer a meaningful addition to oral propranolol therapy. Lasers with shorter wavelengths offer improved outcomes with decreased downtime for pigmented lesions. General anesthesia in the pediatric population continues to be a controversial topic, and the decision to perform laser under general versus topical anesthesia requires discussion with family of risks and benefits. SUMMARY Primary care providers can benefit their patients by prompt referral to dermatology for discussion of laser treatment. Port-wine birthmarks require referral in the first weeks of life so that laser treatment can be initiated if appropriate. Although many dermatologic conditions cannot be completely cleared or cured with laser, treatment can offer meaningful outcomes and benefit for patients and families.

Abstract
A decrease in the activity of the insulin signaling system of the brain, due to both central insulin resistance and insulin deficiency, leads to neurodegeneration and impaired regulation of appetite, metabolism, endocrine functions. This is due to the neuroprotective properties of brain insulin and its leading role in maintaining glucose homeostasis in the brain, as well as in the regulation of the brain signaling network responsible for the functioning of the nervous, endocrine, and other systems. One of the approaches to restore the activity of the insulin system of the brain is the use of intranasally administered insulin (INI). Currently, INI is being considered as a promising drug to treat Alzheimer's disease and mild cognitive impairment. The clinical application of INI is being developed for the treatment of other neurodegenerative diseases and improve cognitive abilities in stress, overwork, and depression. At the same time, much attention has recently been paid to the prospects of using INI for the treatment of cerebral ischemia, traumatic brain injuries, and postoperative delirium (after anesthesia), as well as diabetes mellitus and its complications, including dysfunctions in the gonadal and thyroid axes. This review is devoted to the prospects and current trends in the use of INI for the treatment of these diseases, which, although differing in etiology and pathogenesis, are characterized by impaired insulin signaling in the brain.
