Presence of Increased Mast Cells in Infants and Children with Volume and Variety Limited Intake

Background: Reports indicate patients with feeding difficulties demonstrate signs of inflammation on biopsies, notably eosinophilia, but it is unknown whether mast cell density contributes to variety or volume limitation symptoms. The aim of our study was to evaluate eosinophil and mast cell density of EGD biopsies in pediatric patients with symptoms of decreased volume or variety of ingested foods. Methods: We conducted a single-center, retrospective chart review of EMRs for all new feeding clinic patients between 0 and 17 years of age. Patients were categorized by symptoms at the initial visit as well as eosinophil and mast cell densities in those with EGD biopsies. Ten patients were identified as controls. Results: We identified 30 patients each with volume and variety limitation. Antral mast cell density was increased in 32.1% of variety-limited patients, 37.5% of volume limited patients, and in no controls; Duodenal mast cell density was increased in 32.1% of variety-limited patients, 40.6% of volume-limited patients, and in no controls. Conclusions: In both variety- and volume-limited patients, antral and duodenal mast cell densities were increased. These associations warrant further investigation of the mechanism between mast cells and development of feeding difficulties, allowing more targeted pediatric therapies.

The Torque Teno Virus Titer in Saliva Reflects the Level of Circulating CD4+ T Lymphocytes and HIV in Individuals Undergoing Antiretroviral Maintenance Therapy

IntroductionTorque teno virus (TTV) is a non-pathogenic virus present in body fluids. Its titer in the circulation increases in association with immune suppression, such as in HIV-infected individuals. We evaluated if the TTV titer in saliva from HIV-positive individuals undergoing antiretroviral therapy (ART) was related to the circulating CD4+ T lymphocyte concentration and the HIV titer.MethodsSaliva was collected from 276 asymptomatic individuals undergoing ART, and an additional 48 individuals positive for AIDS-associated Kaposi's Sarcoma (AIDS-KS). The salivary TTV titer was measured by gene amplification analysis. The circulating CD4+ T lymphocyte and HIV levels were obtained by chart review.ResultsTTV was detectable in saliva from 80% of the asymptomatic subjects and 87% of those with AIDS-KS. In the asymptomatic group the median log10 TTV titer/ml was 3.3 in 200 males vs. 2.4 in 76 females (p < 0.0001). TTV titer/ml was 3.7 when HIV was acquired by intravenous drug usage, 3.2 when by sexual acquisition and 2.4 when blood transfusion acquired. The salivary TTV titer was inversely correlated with the circulating CD4+ T lymphocyte level (p < 0.0001) and positively correlated with the circulating HIV concentration (p = 0.0005). The median salivary TTV titer and circulating HIV titer were higher, and the CD4+ count was lower, in individuals positive for AIDS-KS than in the asymptomatic subjects (p < 0.0001).ConclusionThe TTV titer in saliva is a potential biomarker for monitoring immune status in individuals undergoing ART.

Oral Care in Acute Stroke

Purpose: Stroke impacts independent activities, particularly personal care such as oral hygiene. Existing guidelines lack details about how to provide effective oral care. This study explores the frequency of oral care based on staff adherence to oral care policies. Method: As part of a quality improvement initiative, we conducted a retrospective chart review of 30 consecutive stroke admissions to an acute care hospital. Patients with primary intracerebral hemorrhage or ischemic stroke were eligible. Sources of information included a decision support database and an electronic chart review. Data collection included length of hospitalization, stroke type, presence of infections, oral mechanism exam, dysphagia evaluations, and daily personal care provision by nursing staff (e.g., oral care and bathing). Results: Twenty-seven patients met the inclusion criteria. They had a mean age of 74 years, and 52% were men. Most had supratentorial stroke (86%) with comparable frequencies of right (48%) and left (52%) hemisphere lesions. In over half of the cases, provision of oral care was not documented at any point during the patients' hospitalization ( Mdn = 128 hr). Pericare and bathing were about twice and 4 times more frequent than oral care, respectively. Conclusions: Oral care after stroke is challenging. Existing oral care recommendations from stroke guidelines lack sufficient detail and warrant reconsideration for optimal and routine implementation particularly in acute settings. Education around oral care and associated protocols are necessary to advance oral care practices and improve stroke recovery.

An Interprofessional Approach to Chronic Pain Management and Education

Background and Objectives: The opioid epidemic highlights the importance of evidence-based practices in the management of chronic pain and the need for improved resident education focused on chronic pain treatment and controlled substance use. We present the development, implementation, and outcomes of a novel, long-standing interprofessional safe prescribing committee (SPC) and resulting policy, protocol, and longitudinal curriculum to address patient care and educational gaps in chronic pain management for residents in training. Methods: The SPC developed and implemented an opioid prescribing policy, protocol, and longitudinal curriculum in a single, community-based residency program. We conducted a postcurriculum survey for resident graduates to assess impact of knowledge gained. We conducted a retrospective chart review for patients on chronic opioid therapy to assess change in morphine equivalent dosing (MED) and pain scores pre- and postintervention. Results: A postcurriculum survey was completed by 20/26 (77%) graduates; 18/20 (90%) felt well-equipped to manage chronic pain based on their residency training experience. We completed a retrospective chart review on 57 patients. We found a significant decrease in MED (-20.34 [SE 5.12], P<.0001) at intervention visit with MED reductions maintained through the postintervention period (-9.43 per year additional decrease [SE 5.25], P=.073). We observed improvement in postintervention pain scores (P=.017). Conclusions: Our study illustrates the effectiveness of an interprofessional committee in lowering prescribed opioid doses and enhancing chronic pain education in a community-based residency setting.

Polymorphism of folate metabolism genes and thrombotic complications in patients with functionally single ventricle

Aim. To analyze the relationships between the carriage of polymorphic variants in the folate metabolism genes and the development of thrombotic complications in patients with single ventricle (SV) during surgical treatment.Material and Methods. A total of 102 children with SV were examined in the performed research. All patients underwent surgical hemodynamic correction of congenital heart disease (CHD). According to a retrospective chart review, thrombosis was diagnosed in 12.7 % of the examined patients with SV. The analysis of polymorphism in the MTR A2756G enzyme gene revealed significant differences between the groups of patients with a history of thrombosis and without it.Results. We found that the risk of developing thrombosis was associated with the carriage of homozygous genotype 2756AA of the MTR enzyme gene (OR = 11.21; 95% CI: 1.39–89.96; p = 0.023).

Crotalidae Polyvalent Immune Fab and Cost-Effective Management of Hospital Admissions for Snakebites

Background Venomous snakebites are a common clinical scenario in the Southeastern United States. CroFab® (Crotalidae Polyvalent Immune Fab (Ovine), BTG, Wales, UK) antivenom is indicated in cases involving pit vipers and is known to be expensive. The treatment protocol for snakebites is based on clinically subjective measures triggering the application, or escalation of, antivenom administration. The purpose of this study is to characterize the use of CroFab at our institution and to evaluate the impact of its use regarding cost and overall outcomes. We suspect that it is often used but potentially less often needed. We hypothesized that CroFab use was associated with increased length of stay (LOS) without an observed difference in patient outcomes. Materials and Methods A retrospective chart review of snakebite patients at our level-1 trauma center from 2000 to 2016 was performed. Snakebite location, snake species, number of vials of CroFab administered, hospital LOS, intensive care unit (ICU) LOS, and complications were identified for each patient. Patients were divided into CroFab (C) and no CroFab (NC) groups. Results One hundred ninety patients with venomous snakebites were included. 53.7% of patients received CroFab. There was no difference in the complication rate of C versus NC groups, ( P = .1118). CroFab use was associated with longer hospital LOS ( P < .0001) and ICU LOS ( P < .0001). Discussion CroFab use was associated with increased LOS in our patient population. There was no difference in observed outcomes between the C and NC groups. These findings imply that CroFab is potentially over-used in our patient population.

Evaluating the Prognostic Implication of the Collins Histology Scoring System in a Pediatric Eastern Ontario Population With Eosinophilic Esophagitis

Introduction: Collins et al developed a histology scoring system (EoE HSS) to assess multiple pathologic features. The aim of this study is to identify if the EoE HSS can better detect endoscopic and symptom improvement vs the Peak Eosinophilic Count (PEC). Methods: A retrospective chart review was performed for patients during 2014–2016. All patients ≤18 years old with a diagnosis of EoE and whose records included initial and follow-up upper gastrointestinal endoscopies were included. Severity and extent of endoscopic features were scored using 8 parameters, from normal to maximum change for each location of the esophageal biopsy. Results: Forty patients with EoE were included in the study, of which 35 (87.5%) patients demonstrated symptom and 25 (62.5%) endoscopic improvement at the time of follow-up. In the proximal esophagus, the EoE HSS outperformed the change in eosinophil count of the Children’s Hospital of Eastern Ontario (CHEO) practice in predicting endoscopic improvement by 16.8% when examining the change in grade and 17.1% when examining the change in stage scores. Conclusions: At our institution, adoption of the EoE HSS in assessing biopsies of EoE patients might be warranted, compared to the traditional practice. However, a bigger sample size may give a more robust difference in all locations.

Outcomes of eosinophilic esophagitis in patients managed in a multidisciplinary clinic

Background: Eosinophilic esophagitis is a complex disease with an increasing prevalence. Multidisciplinary teams are often needed to manage this difficult-to-treat condition. Objective: To observe the clinical and histologic outcomes of patients with eosinophilic esophagitis after management in a multidisciplinary clinic. Methods: An observational, retrospective chart review was conducted to include all patients referred to the Walter Reed National Military Medical Center multidisciplinary eosinophilic esophagitis clinic between August 2012 and February 2021. Only patients who had at least one esophagogastroduodenoscopy before referral, one or more visits and endoscopy after multidisciplinary management, and documented clinical symptoms were included. Statistical analysis was performed by using McNemar and Wilcoxon tests. Results: A total of 103 patients were included in the study, with a mean age at diagnosis of 17.9 years. Management in the multidisciplinary clinic was associated with a reduction in solid-food dysphagia by 70.9%, poor growth by 70.8%, and emesis or regurgitation by 87.5%. We observed that 48.5% and 62.1% had histologic remission (<15 eosinophils/hpf) on the initial and any post-multidisciplinary endoscopy, respectively. Only seven patients (5.8%) with two or more visits and endoscopies did not achieve histologic remission. More than two-thirds of the patients (68.9%) required combination therapy to achieve remission. Conclusion: Although an observational study, these findings may suggest that the management of patients with eosinophilic esophagitis in a multidisciplinary clinic may improve the likelihood of clinical and histologic remission. Targeted management with a multidisciplinary approach may reduce overall morbidity and slow disease progression; however, more research is needed.
