Impact of the 2022 national formula shortage on clinical decision-making of healthcare providers in switching amino acid formulas for infants with cow's milk protein allergy: a survey-based study.

Background: In 2022, the United States experienced a national shortage of infant formula due to a global supply chain crisis and a large-scale domestic formula recall. The existing literature on healthcare providers' (HCPs) clinical decision-making during formula shortages is limited. This study aims to analyze the factors influencing pediatric HCP clinical decision-making when switching between amino acid formulas (AAF) for managing cow's milk protein allergy (CMPA) in infants under 24 months of age during an unprecedented national formula shortage. Methods: The study included pediatric HCPs with experience managing CMPA in infants and toddlers under 24 months during the formula shortage from January 2022 to November 2022. A de-identified survey comprising 26 questions examining driving factors used in clinical decision-making was administered to pediatric HCPs using a real-time mobile data collection tool. Results: Among the surveyed pediatric HCPs (n = 75), the factors most frequently considered as "extremely important" when switching to another AAF included safety (85%), tolerability (73%), and efficacy (83%). No statistically significant differences were found in HCP ratings among the listed examined factors of the four AAFs. The availability of specific formulas was the only factor that exhibited a statistically significant difference in perceived performance among pediatric HCPs when comparing the four AAFs (p < 0.05). Discussion: This study elucidates the crucial aspects that influenced pediatric HCPs' selection of AAFs for CMPA management during the 2022 formula shortage. The findings highlight the significance of safety, tolerability, efficacy, and availability in the pediatric HCP decision-making processes.

Natural airway as an alternative to intubation for pediatric endoscopic esophageal foreign body removal: A retrospective cohort study of 326 patients.

BACKGROUND: Anesthesia is required for endoscopic removal of esophageal foreign bodies (EFBs) in children. Historically, endotracheal intubation has been the de facto gold standard for airway management in these cases. However, as more elective endoscopic procedures are now performed under propofol sedation with natural airway, there has been a move toward using similar Monitored Anesthesia Care (MAC) for select patients who require endoscopic removal of an EFB. METHODS: In this single-center retrospective cohort study, we compared endoscopic EFB removal with either MAC or endotracheal intubation. Descriptive statistics summarized factors stratified by initial choice of airway technique, including intra- and postanesthesia complications and the frequency of mid-procedure conversion to endotracheal intubation in those initially managed with MAC. To demonstrate the magnitude of associations between these factors and the anesthesiologist's choice of airway technique, univariable Firth logistic and quantile regressions were used to estimate odds ratios (95% CI) and beta coefficients (95% CI). RESULTS: From the initial search, 326 patients were identified. Among them, 23% (n = 75) were planned for intubation and 77% (n = 251) were planned for MAC. Three patients (0.9%) who were initially planned for MAC required conversion to endotracheal intubation after induction. Two (0.6%) of these children were admitted to the hospital after the procedure and treated for ongoing airway reactivity. No patient experienced reflux of gastric contents to the mouth or dislodgement of the foreign body to the airway, and no patient required administration of vasoactive medications or cardiopulmonary resuscitation. Patients had higher odds that the anesthesiologist chose to utilize MAC if the foreign body was a coin (OR, 3.3; CI, 1.9-5.7, p < .001) or if their fasting time was >6 h. Median total operating time was 15 min greater in intubated patients (11 vs. 26 min, p < .001). CONCLUSIONS: This study demonstrates that MAC may be considered for select pediatric patients undergoing endoscopic removal of EFB, especially those who have ingested coins, who do not have reactive airways, who have fasted for >6 h, and in whom the endoscopic procedure is expected to be short and uncomplicated. Prospective multi-site studies are needed to confirm these findings.

Peeling Back the Layers: Sloughing Esophagitis in a Teenager with Chronic Vomiting.

Esophagitis dissecans superficialis (EsoDS) is a rare condition characterized by the shedding of superficial esophageal epithelium. Limited data exists on EsoDS in the pediatric population. We present a case of a 17-year-old female with chronic nausea and vomiting diagnosed with EsoDS. Endoscopy revealed esophageal mucosal sloughing, and histology confirmed esophagitis with mucosal necrosis. EsoDS is underrecognized, and its association with psychoactive medications remains unclear. Fortunately, EsoDS cases tend to resolve spontaneously without complications. Awareness of EsoDS is essential, and further research is needed to understand its prevalence and outcomes in pediatric patients.

Esophageal Heterotopic Pancreas in an Asymptomatic 2-Year-Old With VACTERL Association.

A 2-year-old male with VACTERL association and asthma presented to the emergency room due to asthma exacerbation. Chest radiography revealed lingular pneumonia and thickening of the left paraspinal line of the gastroesophageal junction. Chest computed tomography confirmed a heterogeneous fluid- and gas-filled structure at the left posterior lateral posterolateral aspect of the esophagus, which was suspected to be an esophageal diverticulum on an upper gastrointestinal series. The esophageal diverticulum was excised via left thoracoscopy, and pathological examination revealed pancreatic tissue. Heterotopic pancreas lacks anatomical, vascular, or ductal continuity with the native pancreas. It is usually asymptomatic, but when discovered, it usually occurs later in life. It has been described in the foregut, but is not as common in the esophagus, especially in the pediatric population. This case report highlights the rare occurrence, and importance of considering, esophageal heterotopic pancreas within an esophageal diverticulum in an asymptomatic patient with VACTERL association.

Avoiding Surgery: Endoscopic Treatment of Congenital Duodenal Stenosis.

Duodenal stenosis is a rare congenital anomaly that is typically treated surgically, although endoscopic incisional therapy (EIT) and balloon dilation are minimally invasive alternatives. We present a case of a 15-month-old male with vomiting and difficulty tolerating solid food due to severe congenital duodenal stenosis. The patient underwent EIT and serial duodenal dilation to a diameter of 20 mm, which resulted in significant symptom improvement. Intralesional corticosteroid injection (ISI) was administered to help prevent the duodenal septum from restricturing. The combination of EIT, balloon dilation, and ISI was successful in treating the patient's congenital duodenal stenosis and avoided the need for surgery. However, further studies are required to confirm the efficacy of this treatment approach in this patient population. This report highlights the potential of this minimally invasive approach as an alternative to surgical intervention in the management of congenital duodenal stenosis.

Clinician Experience with Using Hypoallergenic Formulas to Treat Infants with Suspected Cow's Milk Protein Allergy: A Secondary Analysis of a Prospective Survey Cohort.

Purpose: Cow's milk protein allergy (CMPA) is a common condition in infants, but little is known about healthcare providers' clinical experience treating infants with CMPA. To address this gap, we analyzed prospectively collected data from healthcare providers (HCPs) who treated infants under six months old with suspected CMPA using hypoallergenic formulas. The study focused on a commercial extensively hydrolyzed formula containing Lactobacillus rhamnosus GG (ATCC53103) (eHF-LGG) or a commercial amino acid formula (AAF). Methods: In this secondary analysis of prospectively collected survey data, 52 HCPs treated 329 infants under six months old with suspected CMPA using hypoallergenic formulas. A series of two de-identified surveys per patient were collected by HCPs to assess short-term symptom relief in the patients and HCP's satisfaction with the management strategies. The initial survey was completed at the initiation of treatment of CMPA, and the second survey was completed at a follow-up visit. Results: The majority of HCPs (87%) in the study were general pediatricians, and most saw 2 to 10 CMPA patients weekly. Results showed that clinicians reported satisfaction with treatment in 95% of patients in the EHF cohort and 97% of patients in the AAF cohort and achieved expected clinical results in 93% and 97% of patients using eHF and AAF, respectively. Furthermore, few patients were switched from the hypoallergenic formula once initiated. Conclusion: The study provides new insights into HCP perspectives on treating infants with CMPA and supports using hypoallergenic formulas to manage this condition. However, additional prospective controlled studies are needed to confirm these initial findings.

Acute Treatment of Adolescent Cannabinoid Hyperemesis Syndrome With Haloperidol, Lorazepam, and/or Capsaicin: A Single Institution Case Series.

Cannabinoid hyperemesis syndrome (CHS), an under-recognized and seemingly paradoxical condition, arises in some adolescents and adults who chronically use cannabis. It presents acutely with intractable nausea, vomiting, and abdominal pain but standard antiemetic therapy leads to improvement for only a minority of patients. Randomized controlled trial evidence in adults indicates the superiority of haloperidol over ondansetron in alleviating the acute symptoms of CHS, but safe and effective treatment for adolescents with the disorder is currently unknown. The successful use of topical capsaicin has also been reported. We report a case series of 6 adolescent patients with CHS who presented to Johns Hopkins All Children's Hospital and were treated with haloperidol, lorazepam, and/or capsaicin. Four patients given 5 mg intravenous (IV) haloperidol and 2 mg IV lorazepam and 1 patient treated with 5 mg IV haloperidol and peri-umbilical topical capsaicin (0.025%) experienced full acute symptomatic relief. One patient, treated only with topical capsaicin, reported improvement of symptoms with some persistent nausea. Haloperidol/lorazepam, haloperidol/capsaicin, and topical capsaicin alone appear safe and effective in adolescents, but larger studies are required to confirm our findings.

Short-term symptom improvement in infants with suspected cow's milk protein allergy using amino acid formula: a prospective cohort analysis.

Background: Cow's milk protein allergy (CMPA) occurs commonly in infants. While the long-term efficacy of amino acid formulas for managing CMPA is well-established, there is limited data on the short-term symptom improvement of using amino acid formula (AAF). Objective: This study aimed to determine the short-term effects of managing suspected CMPA in infants aged 6 months and under using a commercial AAF. Methods: Healthcare providers who treated infants with suspected CMPA aged 6 months or younger (n = 104) provided de-identified survey data in this prospective study. Healthcare providers scored symptoms for severity from 0 to 3 (none, low, moderate, severe) before using a commercial AAF at Visit 1 and at Visit 2 (3-6 weeks later). Results: Gastrointestinal (94%), skin (87%), respiratory (86%), and uncategorized symptoms (89%) improved from AAF initiation, and these findings were consistent across different follow-up visit durations. Conclusion: This study is the most extensive prospective analysis conducted in the United States examining the short-term change in suspected CMPA symptoms using an AAF. These findings suggest that AAF may decrease the severity of suspected CMPA symptoms in infants 6 months or younger, often by the next follow-up visit. Further randomized controlled trials are required to confirm these initial findings.

Endoscopic Assessment and Serial Balloon Dilatation in a Toddler With Dyskeratosis Congenita-Hoyeraal-Hreidarsson Syndrome Following Bone Marrow Transplant: A Case Report.

We report a 3-year-old patient with suspected oropharyngeal graft-versus-host disease (GVHD) who developed progressive dysphagia to solids and liquids. The patient has a history of Dyskeratosis Congenita-Hoyeraal-Hreidarsson Syndrome with associated bone marrow failure requiring a nonmyeloablative matched sibling hematopoietic stem cell transplant. Esophagram revealed significant narrowing in the cricopharyngeal region. Subsequent esophagoscopy showed a proximal, high-grade pinhole esophageal stricture that was very difficult to visualize and cannulate. High-grade esophageal strictures are uncommon in very young children with GVHD. We believe the patient's underlying Dyskeratosis Congenita-Hoyeraal-Hreidarsson Syndrome in the setting of inflammatory changes seen in GVHD following hematopoietic stem cell transplant set the stage for a high-grade esophageal obstruction. The patient's symptoms improved with serial endoscopic balloon dilation.

Extensively Hydrolyzed Formula Improves Allergic Symptoms in the Short Term in Infants with Suspected Cow's Milk Protein Allergy.

Although extensively hydrolyzed formula is widely accepted for managing cow's milk protein allergy (CMPA) long-term, there is a lack of evidence on its short-term efficacy. This study's objective was to investigate the short-term symptom changes (within 3-6 weeks) of infants diagnosed with CMPA and managed with extensively hydrolyzed formula containing Lactobacillus rhamnosus at their subsequent physician visit. Healthcare providers treating 202 patients diagnosed with CMPA under six months old completed de-identified surveys, which were then analyzed in this prospective study. After their first visit, the patients were started on extensively hydrolyzed formula, and their baseline symptoms were scored on a severity scale of 0-3. Patients were then reevaluated at their next follow-up visit to assess changes in symptom severity. The study found statistically significant improvements in gastrointestinal (93%), skin (83%), respiratory (73%), and uncategorized symptoms (90%). These symptom improvements were consistent across different follow-up visit durations. This study is the largest prospective analysis conducted in the United States evaluating short-term change in CMPA symptoms severity in infants under six months old using extensively hydrolyzed formula. These findings suggest that extensively hydrolyzed formula is associated with clinical symptom relief, which is often noticeable by the next follow-up visit. However, additional randomized control trials are needed to validate these results.

Evolution of left-sided thoracoscopic approach for long gap esophageal atresia repair.

BACKGROUND: Left-sided repair for long gap esophageal atresia (LGEA) has been described for patients with a large leftward upper pouch, no thoracic tracheoesophageal fistula (TEF) nor tracheobronchomalacia (TBM), or as salvage plan after prior failed right-sided repair. We describe our experience with left-sided MIS traction induced growth process. METHODS: We retrospectively reviewed patients who underwent Foker process for LGEA at two institutions between December 2016 and November 2021. Patient characteristics, surgical techniques, and outcomes were reviewed. RESULTS: 71 patients underwent Foker process. Of 34 MIS cases, 28 patients (82%) underwent left-sided repair (median gap length 5 cm) at median age 4 months with median 3 (range 2-8) operations and median 13.5 (IQR 11-21) days on traction until esophageal anastomosis. 9 patients (32%) underwent completely MIS approach, whereas 5 patients (18%) converted to open at first operation and 14 patients (50%) converted to open later in the traction process. Traction was internal in 68%, external in 11%, and combination in 21%. Median follow-up was 15.4 (IQR 7.5-31.7) months after anastomosis. 14% had anastomotic leak managed with antibiotics and/or esophageal vacuum therapy. Median number of esophageal dilations was 3.5 (range 0-13). 18% required stricture resection. 39% underwent Nissen fundoplication. None have needed esophageal replacement. CONCLUSIONS: For multiple reasons including the tendency of both esophageal pouches to have a leftward bias, less tracheal compression by upper pouch, and clean field of surgery for reoperative cases, we now more commonly use left-sided approach for MIS LGEA repair compared to right side, regardless of left aortic arch. LEVEL OF EVIDENCE: Level IV Treatment Study.

Navigating formula shortages: associations of parental perspectives on transitioning to alternative infant formulas for cow's milk protein allergy during the 2022 national formula shortage.

The COVID-19 pandemic led to supply chain disruptions causing a severe shortage of infant formula. The shortage impacted parents of infants with cow's milk protein allergy (CMPA) who rely on specialized formulas. However, research on parent perspectives during formula shortages is limited. We aimed to understand the factors guiding parents' decisions when transitioning to alternative amino acid formula (AAF) or extensively hydrolyzed formula (eHF) during the national formula shortage. We conducted a survey using the ZSMoments platform and found that before the shortage, parents valued safety (83%), tolerability (78%), and reputability (78%) as primary factors in selecting eHFs and AAFs. Post-shortage, formula tolerability (86%), assurance (84%), and safety (80%) gained more importance. Among those switching eHF (n = 54), health care provider recommendations (81%), reputability (78%), taste (78%), and tolerability (78%) were rated as "extremely important." Among those switching AAF (n = 26), top factors included tolerability (77%), assurance (73%), safety (73%), cost-effectiveness (73%), and formula trustworthiness (73%). These data suggest that parents carefully weigh various factors when managing their child's CMPA and transitioning to different AAF or eHF options.

Paediatric cannabinoid hyperemesis.

PURPOSE OF REVIEW: The prevalence of adolescent cannabinoid hyperemesis syndrome (CHS) continues to grow, as clinicians increasingly recognize the presenting features of cyclical nausea, emesis, abdominal pain and relief of symptoms with hot showers, in the setting of chronic cannabinoid use. RECENT FINDINGS: Our understanding of the contributory mechanisms continues to grow, but high-quality evidence of effective treatment in adolescents remains lacking. Current best evidence in the treatment of acute paediatric CHS suggests intravenous rehydration and electrolyte correction, followed by 0.05 mg/kg haloperidol with or without a benzodiazepine. The only long-term treatment remains complete cessation of cannabinoid use. SUMMARY: This article reviews our growing knowledge of adolescent CHS and provides practical guidance for diagnosis, treatment and understanding the underlying mechanisms of the condition.

Prevalence of Gastroesophageal Reflux Disease in Infants With Congenital Muscular Torticollis: A Prospective Cohort Study.

PURPOSE: Clinical experience suggests that gastroesophageal reflux disease (GERD) occurs commonly in infants with congenital muscular torticollis (CMT). However, this is an understudied topic and prospective studies are absent. We determine the prevalence of GERD in infants with CMT, comparing clinical characteristics between CMT infants with and without GERD, and identifying infants with potentially undiagnosed GERD. METHODS: A prospective cohort study of 155 infants with CMT younger than 12 months with and without GERD was evaluated by pediatric physical therapists. RESULTS: GERD prevalence was 30.3%, including 6 (3.9%) infants with undiagnosed GERD. Demographic and clinical characteristics were similar in CMT infants with and without GERD. CONCLUSIONS: This is the first prospective cohort study determining the prevalence of GERD in infants referred for evaluation of CMT. Further prospective studies are needed to determine whether early intervention and treatment of GERD improves outcomes in infants with CMT (see Supplemental Digital Content 1, available at: http://links.lww.com/PPT/A369).

Enteral Nutrition Improves Vital Signs in Children With Bronchiolitis on Noninvasive Ventilation.

OBJECTIVES: In children hospitalized for bronchiolitis, enteral nutrition (EN) practices during noninvasive ventilation (NIV) vary widely. We sought to assess the potential impact of EN by observing changes in physiometric indices (heart rate [HR] and respiratory rate [RR]) before and after EN initiation. METHODS: We performed a retrospective cohort study in children <2 years of age hospitalized for bronchiolitis receiving NIV from 2017 to 2019 in a quaternary ICU. The primary outcome was patient HR and RR before and after EN initiation. Descriptive data included demographics, anthropometrics, comorbidities, NIV parameters, EN characteristics, and general hospital outcomes. Analyses included paired comparative and descriptive statistics. RESULTS: Of the 124 children studied, 85 (69%) were permitted EN at a median of 12 (interquartile range [IQR]: 7 to 29) hours. The route was oral (76.5%), nasogastric (15.3%), or postpyloric (8.2%) and was predominantly started during high-flow nasal cannula (71%) at flow rates of 1 (IQR: 0.7 to 1.4) L/kg per minute. After EN initiation, reductions in the median RR (percentage change: -11 [IQR: -23 to 3]; P < .01) and HR (percentage change: -5 [IQR: -12 to 1]; P < .01) were noted. Those permitted EN were younger (5 [IQR: 2 to 11] vs 11 [IQR: 3 to 17] months; P < .01) and more likely to have bronchopulmonary dysplasia (19% vs 5%; P = .04). Malnutrition rates, comorbidities, admission timing, flow rates, length of stay, and NIV duration did not differ for those provided or not provided EN. No aspiration events were observed. CONCLUSIONS: Reductions between pre- and postprandial RR after EN initiation among children hospitalized for bronchiolitis on NIV were observed without clinically significant aspiration. These findings support existing data that suggest that EN is safe during NIV and may lessen distress in some patients.

Percutaneous Endoscopic Gastrostomy Enhances Interstage Growth in Infants With Hypoplastic Left Heart Syndrome.

OBJECTIVES: Infants with hypoplastic left heart syndrome undergoing staged palliation commonly experience chronic growth failure and malnutrition. Greater patient weight at stage 2 palliation (Glenn) is thought to be associated with improved perioperative outcomes. We aimed to compare weight for age z score and interstage growth velocity in children with and without a percutaneous endoscopic gastrostomy prior to Glenn and hypothesize that those with a percutaneous endoscopic gastrostomy experience-enhanced interstage growth and reduced malnutrition rates. DESIGN: Single-center, retrospective cohort study. SETTING: A total of 259-bed, quaternary, pediatric referral center. PATIENTS: Infants with hypoplastic left heart syndrome from 2007 to 2016 with and without percutaneous endoscopic gastrostomy insertion after initial palliation (Norwood). INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Primary outcomes were weight for age z score (at birth, Norwood, Norwood discharge, and Glenn), interstage growth velocity, and moderate-to-severe malnutrition (weight for age z score<-2) rates. Secondary outcomes were lengths of stay, mechanical ventilation rates after Glenn, and mortality. Statistical analyses included chi-square, Wilcoxon rank-sum, student's t, paired testing, and exploratory logistic regression. Of the 69 infants studied, 47 (68%) had percutaneous endoscopic gastrostomy insertion at a median of 156 (interquartile range, 115-158) days prior to Glenn. Among children with and without percutaneous endoscopic gastrostomy, we observed no differences in demographics, comorbidities, cardiothoracic surgical times, postoperative Glenn outcomes (length of stay, mechanical ventilation rate, peak 24-hr lactate, nitric oxide use, extracorporeal life support rate, or mortality), weight for age z score at birth, and weight for age z score at Norwood. At the time of percutaneous endoscopic gastrostomy insertion, weight for age z score was -2.5 ± 1.3 and subsequent growth velocity increased from 8 ± 7 to 40 ± 59 g/d (p < 0.01). From Norwood discharge to the date of Glenn, weight for age z score increased in infants with percutaneous endoscopic gastrostomy (-2.5 ± 1.1 to -1.5 ± 1.4 [p < 0.01]) with a large reduction in moderate-to-severe malnutrition rates (76-36%; p < 0.01). In general, weight for age z score at the time of Glenn was associated with reduced postoperative mortality (odds ratio, 0.3; 95% CI, 0.09-0.95; p = 0.04). CONCLUSIONS: Infants undergoing palliation for hypoplastic left heart syndrome with percutaneous endoscopic gastrostomy insertion prior to Glenn had improved growth velocity and dramatically reduced rates of moderate-to-severe malnutrition rates (40% reduction). In addition, we noted weight for age z score at when Glenn was associated with improved postoperative Glenn survival. No complications from percutaneous endoscopic gastrostomy were noted. Placement of a percutaneous endoscopic gastrostomy improved weight for age z score, enhanced interstage growth, and reduced malnutrition rates for this at-risk population of malnourished children.

Gastric Xanthoma in the Pediatric Population: A Possible Herald for Malignancy?

Gastric xanthoma is frequently an incidental finding on upper endoscopy in adults. Gastric xanthomas (GX) can be mistaken for malignancies and warrant prompt histologic diagnosis. The underlying etiology is not fully understood; however, it has been linked to Helicobacter pylori gastritis and gastric cancer. GX in the pediatric population is largely unreported in the literature. Because of the relative rarity, documentation with case reports are essential to provide as much data as possible to see if there is a correlation between GX and malignant potential in the pediatric population. Our group is reporting two cases, a 10-year-old male and a 7-year-old male, both who presented with chronic dysphagia, upper abdominal pain, nausea, vomiting, and loss of appetite. Upper endoscopies for both patients revealed small polypoid lesions located in the antrum with foamy histiocytes on histology, leading to the diagnosis of gastric xanthoma.
