Laryngeal clefts in Prader-Willi syndrome: Feeding difficulties and aspiration not always caused by hypotonia

Feeding difficulties, aspiration, and failure to thrive in infancy are commonly seen in patients with Prader-Willi Syndrome (PWS) and attributed to hypotonia. Patients with PWS and laryngeal clefts were identified by review of medical records at three tertiary care children's hospitals between 2017 and 2022. We present three patients with PWS with feeding difficulties who were also found to have laryngeal clefts which likely contributed to their feeding difficulties. Additional factors such as airway anomalies should be considered in patients with PWS, especially when swallowing dysfunction, dysphagia, or abnormal swallow evaluations are present.

Pediatric Aerodigestive Medicine: Advancing Collaborative Care for Children With Oropharyngeal Dysphagia

OBJECTIVES

Aerodigestive disorders encompass various pathological conditions affecting the lungs, upper airway, and gastrointestinal tract in children. While advanced care has primarily occurred in specialty centers, many children first present to general pediatric gastroenterologists with aerodigestive symptoms necessitating awareness of these conditions. At the 2021 Annual North American Society for Pediatric Gastroenterology, Hepatology and Nutrition meeting, the aerodigestive Special Interest Group held a full-day symposium entitled, Pediatric Aerodigestive Medicine: Advancing Collaborative Care of Children with Aerodigestive Disorders. The symposium aimed to underline the significance of a multidisciplinary approach to achieve better outcomes for these complex patients.

METHODS

The symposium brought together leading experts to highlight the growing aerodigestive field, promote new scientific and therapeutic strategies, share the structure and benefits of a multidisciplinary approach in diagnosing common and rare aerodigestive disorders, and foster multidisciplinary discussion of complex cases while highlighting the range of therapeutic and diagnostic options. In this article, we showcase the diagnostic and therapeutic approach to oropharyngeal dysphagia (OPD), one of the most common aerodigestive conditions, emphasizing the role of a collaborative model.

CONCLUSIONS

The aerodigestive field has made significant progress and continues to grow due to a unique multidisciplinary, collaborative model of care for these conditions. Despite diagnostic and therapeutic challenges, the multidisciplinary approach has enabled and greatly improved efficient, high-quality, and evidence-based care for patients, including those with OPD.

A multi‐disciplinary approach to chronic cough in children

Objectives

(1) To highlight the important causes of chronic and recurrent cough in children. (2) To discuss multidisciplinary approach to management of chronic/recurrent pediatric cough.

Methods

Review of scholarly articles, guidelines, expert panels via PubMed and Google Scholar.

Conclusion

Chronic cough (CC) in children is mainly attributed to persistent bacterial bronchitis, asthma, nonspecific cough, and gastroesophageal reflux disease (GERD) symptoms. A multi‐disciplinary approach is cost‐effective and aids with earlier diagnosis and appropriate treatment. Congenital or acquired narrowing of the subglottis is the leading ENT cause for recurrent croup (RC) in children. Laryngeal cleft‐type 1 is commonly seen in children with recurrent aspiration and CC. Children are usually referred to pulmonologists for wet cough not responding to treatment. Eosinophilic esophagitis (EoE) and GERD should be considered in the differential diagnosis of CC in children with both respiratory symptoms and failure to thrive.

Eosinophilic esophagitis with and without airway involvement in children - A comparative analysis

BACKGROUND

Eosinophilic esophagitis (EoE) is an allergic disease characterized by marked eosinophilic infiltration and inflammation of the esophagus eventually leading to esophageal dysfunction. This condition at times may involve the airway leading to breathing difficulties.

OBJECTIVE

To compare the course of EoE in patients with or without airway involvement.

METHODS

A retrospective chart review was done on patients with a diagnosis of Eosinophilic Esophagitis and that were managed in our Aerodigestive clinic from 2012 to 2018. A total of 121 EoE patients were included in the study. Each patient's disease course was examined for pertinent information including - but not limited to - age at presentation, allergies, endoscopic and pathology results, treatments prescribed, and time to resolution. The data was analyzed for any differences between the airway and non-airway groups for each of these variables.

RESULTS

The variables that were analyzed showed no significant difference between patients suffering from EoE with (n = 19) and without (n = 102) airway involvement. However, patients with airway disease trended towards being younger in age at presentation as compared to those without airway symptoms (6.68 years vs. 9.69 years, p = 0.69). Analysis of endoscopic and pathology findings revealed no difference. Similarly, no differences were found between the prescribed treatments. Kaplan-Meier estimates of time to disease remission indicated that 50% of patients had resolution at one year, regardless of airway involvement (p = 0.31).

CONCLUSIONS

Our findings indicate that the disease course of patients with EoE does not vary depending on the presence of airway symptoms. Thus, patients with airway symptoms should not be diagnosed or treated any different than those without airway symptoms.

Suppression of allelic recombination and aneuploidy by cohesin is independent of Chk1 in Saccharomyces cerevisiae

Sister chromatid cohesion (SCC), which is established during DNA replication, ensures genome stability. Establishment of SCC is inhibited in G2. However, this inhibition is relived and SCC is established as a response to DNA damage, a process known as Damage Induced Cohesion (DIC). In yeast, Chk1, which is a kinase that functions in DNA damage signal transduction, is considered an activator of SCC through DIC. Nonetheless, here we show that, unlike SCC mutations, loss of CHK1 did not increase spontaneous or damage-induced allelic recombination or aneuploidy. We suggest that Chk1 has a redundant role in the control of DIC or that DIC is redundant for maintaining genome stability.

Diagnosis of supra-esophageal gastric reflux: correlation of oropharyngeal pH with esophageal impedance monitoring for gastro-esophageal reflux

BACKGROUND

Oropharyngeal (OP) pH monitoring has been developed as a new way to diagnose supra-esophageal gastric reflux (SEGR), but has not been well validated. Our aim was to determine the correlation between OP pH and gastro-esophageal reflux (GER) events detected by multichannel intraluminal impedance-pH (MII-pH).

METHODS

Fifteen patients (11 males, median age 10.8 years) with suspected GER were prospectively evaluated with ambulatory 24-h OP pH monitoring (positioned at the level of the uvula) and concomitant esophageal MII-pH monitoring. Potential OP events were identified by the conventional pH threshold of <4 and by the following alternative criteria: (i) relative pH drop >10% from 15-min baseline and (ii) absolute pH drop below thresholds of <5.5, 5.0, and 4.5. The 2-min window preceding each OP event was analyzed for correlation with an episode of GER detected by MII-pH.

KEY RESULTS

A total of 926 GER events were detected by MII-pH. Application of alternative pH criteria increased the identification of potential OP pH events; however, a higher proportion of OP events had no temporal correlation with GER (45-81%), compared with the conventional definition of pH < 4 (40%). A total of 306 full-column acid reflux episodes were detected by MII-pH, of which 10 (3.3%) were also identified by OP pH monitoring.

CONCLUSIONS & INFERENCES

Use of extended pH criteria increased the detection of potential SEGR events, but the majority of decreases in OP pH were not temporally correlated with GER. Oropharyngeal pH monitoring without concurrent esophageal measurements may overestimate the presence of SEGR in children.

The efficacy of proton pump inhibitors for the treatment of asthma in adults: a meta-analysis

BACKGROUND

Gastroesophageal reflux disease occurs frequently among patients with asthma. Therapy with proton pump inhibitors (PPIs) to improve asthma control remains controversial. We sought to evaluate the efficacy of PPIs in treatment of asthma using objective and subjective outcome measures.

METHODS

A literature search was undertaken using MEDLINE (1950-January 2010), PubMed (1950-January 2010), EMBASE (1980-January 2010), and Cochrane Central Register of Controlled Trials (through January 31, 2010). Randomized, placebo-controlled trials evaluating the efficacy of PPIs for treatment of asthma in adults were selected. The primary outcome of interest was morning peak expiratory flow (PEF) rate. Secondary outcomes included objective (evening PEF rate and forced expiratory volume in 1 second) and subjective (asthma symptoms score and Asthma Quality of Life Questionnaire score) measures. Influence of study characteristics on outcomes was examined by subgroup analyses and meta-regression.

RESULTS

Eleven trials (2524 patients) met inclusion criteria. Overall, patients had a higher mean morning PEF rate after treatment with PPIs compared with placebo (mean difference, 8.68 L/min [95% confidence interval, 2.35-15.02]). No significant single large-study effect, temporal effect, or publication bias was seen. Subgroup analysis revealed a trend toward a larger improvement in morning PEF rate in studies enrolling only patients with gastroesophageal reflux disease (mean difference, 16.90 L/min [95% confidence interval, 0.85-32.95]). Analyses of secondary outcomes (asthma symptoms score, Asthma Quality of Life Questionnaire score, evening PEF rate, and forced expiratory volume in 1 second) showed no significant difference between PPIs and placebo.

CONCLUSIONS

Proton pump inhibitor therapy in adults with asthma results in a small, statistically significant improvement in morning PEF rate. The magnitude of this improvement, however, is unlikely to be of meaningful clinical significance. There is insufficient evidence to recommend empirical use of PPIs for routine treatment of asthma.

Functional abdominal pain and irritable bowel syndrome in children and adolescents

Functional abdominal pain (FAP) and irritable bowel syndrome (IBS) are both associated with recurrent abdominal pain and are among the most commonly diagnosed medical problems in pediatrics. The majority of patients with mild complaints improve with reassurance and time. For a distinct subset of patients with more severe and disabling illness, finding effective treatment for these disorders remains a challenge. Based on the biopsychosocial model of functional disease, the Rome III criteria have helped frame FAP and IBS in terms of being a positive diagnosis and not a diagnosis of exclusion. However, the lack of a single, proven intervention highlights the complex interplay of pathologic mechanisms likely involved in the development of childhood FAP and IBS and the need for a multidisciplinary, integrated approach. This article discusses the epidemiology, proposed mechanisms, clinical approach and therapeutic options for the management of FAP and IBS in children and adolescents.

Management of functional abdominal pain and irritable bowel syndrome in children and adolescents

Functional abdominal pain (FAP) and irritable bowel syndrome (IBS) are among the most commonly diagnosed medical problems in pediatrics. Symptom-based Rome III criteria for FAP and IBS have been validated and help the clinician in making a positive diagnosis. The majority of patients with mild complaints improve with reassurance and time. For a distinct subset of patients with more severe and disabling illness, finding effective treatment for these disorders remains a challenge. Over the years, a wide range of therapies have been proposed and studied. The lack of a single, proven intervention highlights the complex interplay of biopsychosocial factors probably involved in the development of childhood FAP and IBS, and the need for a multidisciplinary, integrated approach. This article reviews the current literature on the efficacy of pharmacologic, dietary and psychosocial interventions for FAP and IBS in children and adolescents.

Knowledge and attitudes regarding cardiovascular disease risk and prevention in patients with coronary or peripheral arterial disease

BACKGROUND

We compared perceptions regarding risk of cardiovascular events and benefits of cardiovascular disease (CVD) risk factor reduction between patients with peripheral arterial disease (PAD), patients with coronary artery disease (CAD), and patients without atherosclerosis (no disease).

METHODS

Participants with no disease (n = 142) had a normal ankle-brachial index and no clinically evident atherosclerosis (group 1). The PAD participants (n = 136) had an ankle-brachial index less than 0.90 and no other clinically evident atherosclerosis (group 2). Participants with CAD (n = 70) had a normal ankle-brachial index and a history of heart disease (group 3). Participants were interviewed regarding risk of mortality, CVD, and the importance of CVD risk factor reduction for hypothetical patients with PAD and CAD.

RESULTS

All groups reported that risks of myocardial infarction, stroke, and death were higher for a patient with CAD than for a patient with PAD. Group 2 was less likely than group 3 to believe that PAD is associated with an extremely high risk of stroke (13.3% vs 28.7%; P =.005) or mortality (10.9% vs 26.6%; P =.003). Group 2 was less likely than group 1 to believe that a patient with PAD has a very high risk of myocardial infarction (13.1% vs 23.8%; P =.02), stroke (13.3% vs 27.5%; P =.003), or mortality (10.9% vs 24.3%; P =.004). Compared with group 3, a smaller percentage of patients in group 2 reported that cholesterol lowering was very important in PAD (57.5% vs 75.8%; P =.005).

CONCLUSIONS

Compared with other patients, those with PAD underestimated the high risk of cardiovascular events associated with PAD and the benefits of cholesterol-lowering therapy. These findings may help explain the low rates of CVD risk factor control previously reported in patients with PAD.
