RESUMEN

Pilomyxoid astrocytoma (PMA) is a subtype of pilocytic astrocytoma (PA). PMA tends to exhibit a more aggressive course compared to PA. We present a case of a two-year-old male with a PMA in the suprasellar region who presented with developmental regression, loss of previously attained milestones such as the ability to hold his neck, walk, and talk, along with hypotonia in all four limbs. Serum cortisol and thyroid-stimulating hormone (TSH) levels were measured to rule out endocrine disturbances and were within normal limits. Magnetic resonance imaging (MRI) of the brain showed a solid lesion in the suprasellar region, extending into the pituitary and interpeduncular fossae, compressing the pituitary gland, and effacing the third ventricle, causing cerebrospinal fluid (CSF) flow obstruction and lateral ventricle dilation. The tumor appears hypointense on T1 and hyperintense on T2, with fluid-attenuated inversion recovery (FLAIR), peripheral contrast enhancement, and no calcification, consistent with PMA. The CSF analysis was negative for malignant cells. Histopathological examination revealed monomorphous bipolar and spindle cells in an angiocentric pattern with a myxoid background, without rosenthal fibers, mitoses, or eosinophilic granular bodies, consistent with PMA but not seen in PA. Immunohistochemistry showed strong positivity for glial fibrillary acidic protein (GFAP) and S100, with a Ki-67 index of 3-4%, indicating a low-grade tumor. The preferred treatment is surgical resection, but due to the tumor's deep location and potential long-term neurological effects, the parents opted against surgery. A ventriculoperitoneal shunt was placed to alleviate CSF flow, following which the child showed mild improvement in symptoms. Treatment of nonresectable astrocytomas was controversial, but gross total surgical resection offers better disease control. Chemotherapy is for patients with recurrence or where total resection of the tumor is not possible, and radiotherapy, though the long-term disease control is good, has a variable visual outcome.

RESUMEN

Introduction In certain fields such as anesthesia and critical care, technical incidents are rare events; however, when they occur, they disrupt workflow, optimal patient care, and survival, with human factors often implicated. In pediatric resuscitation, the impact of these incidents on patient care has not yet been thoroughly explored through simulation. Consequently, we investigated how healthcare teams integrate technical incidents in critical situations and whether this interferes with the adequate management of patients. Materials & methods In a single-blind randomized study utilizing high-fidelity simulation, we incorporated a pediatric scenario involving hypoxemia in an intubated and ventilated infant where the endotracheal tube (ETT) was obstructed. A technical incident (disconnected oxygen supply) was either present (TI+) or absent (TI-) in the scenario. We compared reaction times for "removal of the obstructed ETT" between the two groups (TI+ and TI-). Additionally, we recorded and analyzed reaction times for "bag ventilation" and "repair of the technical incident" in the TI+ group. To assess the scenario's credibility, we conducted an analysis comparing the medians of evaluation forms that were anonymously completed by participants at the end of the sessions. Results In total, 10 simulation sessions were conducted, five TI+ and five TI-. The time required for removal of the obstructed ETT in the presence of a technical incident was significantly prolonged compared to controls (Mann-Whitney test, p=0.03). Furthermore, bag ventilation precedes tube removal in the TI+ group, a contrast to the TI- group, which quickly removes the obstructed ETT before stabilizing the patient with bag-mask ventilation. Conclusion Technical incidents in simulated pediatric scenario adversely affect urgent care in ventilated children. Developing and validating a procedural response to these situations through further simulation is imperative.

RESUMEN

Necrotizing enterocolitis (NEC) and periventricular leukomalacia (PVL) are relatively common conditions in premature infants with low birth weight (VLBW). However, in the current literature, there are limited case reports of patients with concomitant NEC and PVL. We report a case of a premature female born at a gestational age of 25 weeks and five days who developed cystic intracranial lesions after emergent bowel resection due to NEC. Transcranial ultrasound and magnetic resonance imaging confirmed the presence of cystic PVL in the right middle cerebral artery distribution. Several observational studies note the association between spontaneous intestinal perforation, surgical NEC, and the presence of cystic PVL. When infants are unresponsive to medical management for NEC, exploratory laparotomy with resection of the necrotic or perforated intestine is indicated. However, infants treated surgically have poorer neurodevelopmental outcomes than those with medical therapy. Pathogenesis of neurodevelopmental impairment in preterm infants undergoing surgery involves dysfunctional cerebrovascular autoregulation (CAR), which is associated with harmful changes in cerebral perfusion that lead to neuronal injury. Ill preterm infants, such as those with NEC, cannot regulate cerebral perfusion appropriately, and impaired CAR may be present in more than half the preterm infants during laparotomy. Impaired CAR leads to poor cerebral perfusion that potentiates neuronal injury, such as PVL. This case also brings awareness to the need for adherence to screening practices for white matter injury in critical NICU patients through cost-effective transcranial ultrasound.

RESUMEN

Ulcerative colitis (UC) classically presents with abdominal pain, hematochezia, or diarrhea. However, it can present atypically in pediatric and pregnant patients, posing a diagnostic challenge. A healthy, 16-year-old primigravida presented at 18 weeks and six days of gestation with sudden-onset altered mental status and severe anemia. Hematochezia began about 12 hours after admission. She underwent extensive workup, leading to an endoscopic and histopathologic diagnosis of UC, and achieved prenatal remission with high-dose steroids and infliximab. Her pregnancy, however, was complicated by severe preeclampsia, and her child's post-delivery course was medically complex from an unrelated etiology. Pregnancy-onset inflammatory bowel disease (IBD) in the pediatric population is an uncommon but important consideration. Early diagnosis, treatment, and counseling are vital to achieve results comparable to those of patients without IBD.

RESUMEN

Background Advances in perinatal and neonatal medicine have led to an increasing number of infants surviving extreme prematurity (≤27 weeks gestational age, GA). The goal of this study was to examine the respiratory outcomes after neonatal intensive care unit (NICU) discharge of this vulnerable population. We hypothesized that the rates of respiratory hospitalizations are disproportionally higher in the subset of infants born ≤27 weeks GA relative to premature infants born 28-32 weeks GA. Methodology A retrospective longitudinal study of severe premature children (≤32 weeks GA, n = 183) was conducted. We subdivided our sample into extremely preterm infants (≤27 weeks GA; n = 101) and those born very preterm (28-32 weeks GA; n = 82). Our main outcome was the presence of respiratory hospitalizations within 24 months of NICU discharge. Results Extremely premature infants had more than three times higher odds of respiratory hospitalization at 24 months relative to infants born 28-32 weeks GA (adjusted odds ratio = 3.4; 95% confidence interval = 1.8, 6.4; p < 0.01). The increased risk of respiratory hospitalization in extremely premature infants was independent of GA. Regression models identified that the duration of supplemental oxygen and Black/African American ethnicity were significant predictors of respiratory hospitalizations in both prematurity groups independent of gender and birth weight. Conclusions The results support that babies born ≤27 weeks GA represent a distinct high-risk group of severely premature infants that needs novel preventive strategies and targeted interventions to improve their respiratory outcomes after NICU discharge.

RESUMEN

Retinopathy of prematurity (ROP) is an ophthalmologic condition that is one of the leading causes of preventable childhood blindness. Due to the premature nature of blood vessels in preterm infants, retinal vessels are prone to damage. The incidence of ROP ranges with great variation across countries, and this study aims to identify the incidence and its related risk factors. A compilation of studies investigating the incidence of ROP was acquired through the PubMed and Google Scholar databases with a full free text in English filter set. All members of the study were involved in designating studies based on continent and arranging them into a table format. Following this, reasons for the variation in the incidence of ROP were investigated by individually assessing each study. The variation of an increased incidence of ROP seen in low-income countries (LICs) was most likely due to the availability of resources. As a preterm birth can give rise to further complications such as the development of sepsis, it is important to manage preterm birth with the utmost caution. Evidence has suggested that the two key variables in reducing the morbidity and mortality of ROP are the implementation of a screening and treatment protocol with controlled use of oxygen and the availability of resources in hospitals to adequately identify and manage ROP as early as possible. Through a comprehensive overview of the incidence of ROP, it is vital to review screening and treatment protocols in each hospital for ROP, which would aid in preventing its occurrence and initiating early treatment.

RESUMEN

Background Pediatric ACGME (Accreditation Council for Graduate Medical Education) requirements include demonstrated competence in umbilical line placement. Given a waning number of these procedures clinically available to residents, new methods of procedural teaching must be employed. We developed a simulation-based strategy, using adult-learning principles, to teach umbilical venous catheter (UVC) placement to pediatric residents. We also determined whether procedural teaching via simulation increased confidence and competence among pediatric residents in performing the procedure. Methods Out of 23 first-year pediatric residents, eight participated in the study. Participants completed a survey evaluating their self-perceived competence and confidence in umbilical line placement. Their simulated umbilical line placement was assessed using a standardized checklist. Residents were then trained on simulated line placement in small groups by neonatologists. Six months later, residents completed a post-training survey and were assessed while placing simulated lines. Statistical analysis was completed using a paired t-test for parametric data, Wilcoxon signed-rank sum test for non-parametric data, and McNemar's chi-squared test for categorical data. Spearman's correlation was used for ordinal variables and Pearson's correlation was used for continuous variables. Results Nine PGY-1 (post-graduate year-1) residents completed the pre-training survey and simulation, while eight residents completed the post-training survey and simulation. There was an increase in resident confidence in placing umbilical lines six months after completion of the training session (p = 0.015) even though there was no difference in the number of umbilical lines that residents had placed in the intervening time. The residents performed a greater number of steps correctly after the training compared to their performance before the training (p=0.001). There was a statistically significant positive correlation between resident confidence and the number of steps performed correctly (rs(14)= 0.649, p = 0.006). There was no correlation between confidence and the number of umbilical lines placed on live subjects. Conclusion A teaching strategy that allows pediatric residents to struggle to perform UVC placement in a simulated setting, before receiving expert instruction, is effective at increasing their confidence and competence, even in the absence of exposure to human subjects.

RESUMEN

Neonatal lupus erythematosus is a rare disorder with a wide spectrum of clinical presentations. The disease can affect several systems, including the skin, heart, liver, and bone marrow. Thus, a recognition of its different presentations is vital for making a diagnosis. We describe the case of a neonate diagnosed with neonatal lupus, presenting with an acute onset of erythematous skin lesions as the sole manifestation. The patient's mother was healthy with no known medical history or relevant family history.

RESUMEN

Objective This study used a high-fidelity infant mannequin to examine the relationship between the quality of bag valve mask ventilation (BVMV) and how providers of varying levels of experience use visual feedback (e.g., electronic vital signs) to guide their performance. Background BVMV is a common and critical procedure for managing pediatric respiratory emergencies. However, providers do not consistently deliver effective BVMV. Efforts to improve BVMV have ignored the question of how providers effectively use feedback often available during BVMV. Method Six expert and six novice respiratory therapists completed two simulations of an infant requiring BVMV. In one, the technology failed to display SpO2, an important but somewhat redundant visual cue. Eye movements, verbal reports, and ventilation rate (in breaths per minute) were measured in each simulation. Results Regardless of SpO2 availability, eye movements and verbal reports suggested that novices depended strongly on electronic vital signs and when SpO2 was absent ventilated at a faster rate (exceeding the recommended range of ventilation rates) than when SpO2 was present. Experts' ventilation rates were comparable and within the recommended range in both conditions. When SpO2 was absent, experts emphasized information from direct observation of the patient that novices neglected. Conclusion Individual differences in the use of feedback during BVMV contribute to the quality of BVMV. This work bears on the theoretical discussions involving the use of automation and nontechnological cues to guide performance. Application These results have the potential to expand the current understanding of factors underlying effective BVMV with implications for training novice providers.

RESUMEN

OBJECTIVE: We aimed to test whether the use of novel pulse oximetry sounds (sonifications) better informs listeners when a neonate's oxygen saturation (SpO2) deviates from the recommended range. BACKGROUND: Variable-pitch pulse oximeters do not accurately inform clinicians via sound alone when SpO2 is outside the target range of 90% to 95% for neonates on supplemental oxygen. Risk of blindness, organ damage, and death increase if SpO2 remains outside the target range. A more informative sonification may improve clinicians' ability to maintain the target range. METHOD: In two desktop experiments, nonclinicians' ability to detect SpO2 range and direction of change was tested with novel versus conventional sonifications of simulated patient data. In Experiment 1, a "shoulder" sonification used larger pitch differences between adjacent saturation percentages for SpO2 values outside the target range. In Experiment 2, a "beacon" sonification used equal-appearing pitch differences, but when SpO2 was outside the target range, a fixed-pitch reference tone from the center of the target SpO2 range preceded every fourth pulse tone. RESULTS: The beacon sonification improved range identification accuracy over the control display (85% vs. 60%; p < .001), but the shoulder sonification did not (55% vs. 52%). CONCLUSION: The beacon provided a distinct auditory alert and reference that significantly improved nonclinical participants' ability to identify SpO2 range. APPLICATION: Adding a beacon to the variable-pitch pulse oximeter sound may help clinicians identify when, and by how much, a neonate's SpO2 deviates from the target range, particularly during patient transport situations when auditory information becomes essential.
