Food Protein-Induced Enterocolitis Syndrome (FPIES): Review of Recent Guidelines

Abstract

Purpose of Review

To increase understanding of food protein-induced enterocolitis syndrome (FPIES), a non-immunoglobulin E (IgE)-mediated reaction to food, by reviewing a growing body of literature, including recently published international consensus guidelines.

Recent Findings

FPIES primarily affects infants and young children and is characterized by the delayed onset of gastrointestinal symptoms, predominantly repetitive vomiting, in response to a trigger food. Symptoms are often severe and can lead to shock. Diagnosis can be challenging due to a wide differential diagnoses and lack of disease biomarkers. FPIES is a clinical diagnosis, with allergy testing playing a very limited role, if any. Medically supervised oral food challenges are used to monitor resolution of disease, which generally occurs in early childhood.

Summary

FPIES is an important condition presenting to clinicians in a variety of settings. Recent international consensus guidelines and a growing body of literature can better equip practitioners to care for these often-challenging patients.

Dentin sealing and antibacterial effects of silver-doped bioactive glass/mesoporous silica nanocomposite: an in vitro study

Abstract

Objectives

To synthesize a silver-doped bioactive glass/mesoporous silica nanoparticle (Ag-BGN@MSN), as well as to investigate its effects on dentinal tubule occlusion, microtensile bond strength (MTBS), and antibacterial activity.

Materials and methods

Ag-BGN@MSN was synthesized using a modified "quick alkali-mediated sol-gel" method. Demineralized tooth disc models were made and divided into four groups; the following treatments were then applied: group 1—no treatment, group 2—bioglass, group 3—MSN, group 4—Ag-BGN@MSN. Next, four discs were selected from each group and soaked into 6 wt% citric acid to test acid-resistant stability. Dentinal tubule occlusion, as well as the occlusion ratio, was observed using field-emission scanning electron microscopy. The MTBS was also measured to evaluate the desensitizing effect of the treatments. Cytotoxicity was examined using the MTT assay. Antibacterial activity was detected against Lactobacillus casei, and ion dissolution was evaluated using inductively coupled plasma optical emission spectrometry.

Results

Ag-BGN@MSN effectively occluded the dentinal tubule and formed a membrane-like layer. After the acid challenge, Ag-BGN@MSN had the highest rate of dentinal tubule occlusion. There were no significant differences in MTBS among the four groups (P > 0.05). All concentrations of Ag-BGN@MSN used had a relative cell viability above 72%.

Conclusions

Ag-BGN@MSN was successfully fabricated using a modified sol-gel method. The Ag-BGN@MSN biocomposite effectively occluded dentinal with acid-resistant stability, did not decrease bond strength in self-etch adhesive system, had low cytotoxicity, and antibacterial effect.

Clininal relevance

Dentinal tubule sealing induced by Ag-BGN@MSN biocomposite with antibacterial effect is likely to increase long-term stability in DH.
