Abstract
ABSTRACT This article describes an infant who developed a facial rash within minutes of eating certain foods. The rash resolved within 30 minutes. The patient was diagnosed with auriculotemporal syndrome or Frey syndrome, which is characterized by sweating or flushing in the preauricular area when the patient consumes certain foods, especially those that are acidic, sour, or spicy. Because most patients outgrow the syndrome, no treatment is needed.

Abstract
AbstractThe appearance of flushing in the territory of the auriculotemporal nerve after ingestion of foods with a sweet, salty, or sour flavor could suggest Frey's syndrome, especially if the infant has a history of obstetric trauma. This rare and benign condition requires no diagnostic exploration or treatment. A 3-month-old male infant presented with facial flushing since he was 6 weeks' old. Episodes of flushing were stereotypical, over the zone innervated by the left auriculotemporal nerve. They started 10 to 15 seconds after the beginning of the feeding and disappeared after 15 to 20 minutes. At the time of the onset of facial erythema, the infant was exclusively bottle feeding. Diagnosis of Frey's syndrome was made on historical and clinical grounds, and no further testing was needed. Flushing gradually started to fade at the age of 5 months and completely disappeared after 8 months. Introducing solid food did not cause any deterioration of facial erythema. Early recognition of Frey's syndrome is important to avoid unnecessary investigation and therapy. On the other hand, our reported case warns that Frey's syndrome may occur in very early infancy without ingestion of solid food.

Auriculotemporal Frey syndrome not associated with surgery or diabetes: systematic review. Eur J Pediatr 2022; 181:2127-2134. [PMID: 35182195 PMCID: PMC9056449 DOI: 10.1007/s00431-022-04415-w] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/28/2021] [Revised: 02/07/2022] [Accepted: 02/09/2022] [Indexed: 11/25/2022]
Abstract
Patients who undergo salivary gland, neck, or facelift surgery or suffer from diabetes mellitus often develop Frey syndrome (also known as auriculotemporal syndrome or gustatory sweating). Frey syndrome has been occasionally reported to occur in subjects without history of surgery or diabetes but this variant of Frey syndrome has not been systematically investigated. We searched for original articles of Frey syndrome unrelated to surgery or diabetes without date and language restriction. Article selection and data extraction were performed in duplicate. Our systematic review included 76 reports describing 121 individual cases (67 males and 54 females) of Frey syndrome not associated with surgery or diabetes. The age at onset of symptoms was ≤ 18 years in 113 (93%) cases. The time to diagnosis was 12 months or more in 55 (45%) cases. On the other hand, an allergy evaluation was performed in half of the cases. A possible cause for Frey syndrome was detected in 85 (70%) cases, most frequently history of forceps birth (N = 63; 52%). The majority of the remaining 22 cases occurred after a blunt face trauma, following an auriculotemporal nerve neuritis or in association with a neurocutaneous syndrome. The cause underlying Frey syndrome was unknown in 36 cases. Conclusion: Frey syndrome not associated with surgery or diabetes almost exclusively affects subjects in pediatric age and is uncommon and underrecognized. Most cases occur after forceps birth. There is a need to expand awareness of this pseudo-allergic reaction among pediatricians and allergists. What is Known: • Pre-auricular reddening, sweating, and warmth in response to mastication or a salivary stimulus characterize Frey syndrome. • It usually occurs after salivary gland surgery and in diabetes. What is New: • In children, Frey syndrome is rare, and most cases occur after a forceps-assisted birth. • In childhood, this condition is often erroneously attributed to food allergy.

Abstract
OBJECTIVES Frey's syndrome (FS) describes the phenomenon of gustatory sweating and is a cause of significant social embarrassment for sufferers. It has been attributed to aberrant growth of parasympathetic salivatory fibers in the auriculotemporal nerve toward overlying sweat glands. However, the exact mechanism behind this growth is unknown. This review aims to expand and elucidate the theory of aberrant regeneration in FS. METHODS A review of the recent literature on nerve regeneration was conducted in order develop further insights into the etiology of both adult onset and pediatric FS. RESULTS Neurturin, a neurotrophic factor released by both salivary and sweat glands, was identified as a possible key player in the etiology of FS. CONCLUSION Further research into the role of neurturin could help to elucidate the pathogenic mechanisms underlying the condition and might reveal neurturin to be a potential target for pharmacological intervention.

Abstract
BACKGROUND Allergic reactions to food additives are often suspected by families. The aim of this study was to describe oral food challenge (OFC) outcomes in a pediatric cohort with a suspected diagnosis of allergy to food additives (food dyes or sodium benzoate). METHODS All patients who underwent an open OFC to carmine red, cochineal red, erythrosine, patent blue V, tartrazine, yellow sunset S, and/or sodium benzoate were included. A survey was sent to families after testing to evaluate whether the OFC results had altered feeding behaviors with food additives. RESULTS Twenty-three patients were included. The main suspected food was candy (n=11/23; 48%). Only one OFC out of 45 was formally positive for the carmine and cochineal red. Subsequently, most OFCs were negative (44/45; 97.8%). Despite the negativity of the challenge, four families out of 14 reported occurrences of supposed allergic reactions to food additives and six out of 15 continued to completely avoid the additive of concern in their children's diet. CONCLUSIONS Allergies to food additives remain rare. Even if an IgE-mediated allergy was excluded with a negative OFC, families remained suspicious about ready-made products. Health professionals and parents should be reassured about the low risk of food dye intolerance or allergies.

Abstract
BACKGROUND Frey's syndrome is characterised by transient flushing and sometimes facial sweating in the area of the auriculotemporal nerve. It most commonly occurs after parotidectomy, but other causes may include submandibular gland surgery, mandibular condylar fracture, obstetric (forceps) trauma, sympathectomy and metabolic disease. Although the pathophysiology of Frey's syndrome remains controversial, the generally accepted hypothesis is that it occurs as the result of injury to the auriculotemporal nerve.There is currently no clear evidence to establish the efficacy and safety of the different methods used for the treatment of Frey's syndrome, therefore the prevention of this symptom during surgery is important. The main method used for prevention is the interposition of a graft between the skin flap and the parotid bed during surgery. Biomaterials, allograft or autograft can be used for this purpose. OBJECTIVES To evaluate the effects and safety of biomaterial, allograft or autograft interposition for the prevention of Frey's syndrome in patients undergoing parotidectomy, and to identify its effect on prevention and delayed occurrence. SEARCH METHODS The Cochrane ENT Information Specialist searched the Cochrane ENT Trials Register; Cochrane Register of Controlled Trials (CENTRAL; 2019, Issue 2); Ovid MEDLINE; Ovid Embase; CINAHL; Web of Science; ClinicalTrials.gov; ICTRP and additional sources for published and unpublished trials. The date of the search was 5 February 2019. SELECTION CRITERIA We included randomised controlled trials (RCTs) in patients with parotid disease (including tumours, inflammation, trauma etc.) undergoing parotidectomy with a minimal follow-up period of six months. We planned to include trials with interventions including biomaterial, allograft or autograft interposition alone or in combination with other surgical techniques. We included trials that compared any graft interposition and no graft interposition, or different graft interpositions. DATA COLLECTION AND ANALYSIS We used the standard methodological procedures expected by Cochrane. Our primary outcome measures were incidence rate of Frey's syndrome assessed clinically (Minor's starch-iodine test) and other complications (postoperative infection, subjective painful or restricted cervical movement, scar spread, rejection of the graft, complications related to the donor site such as accessory nerve injury and haematoma). Our secondary outcome measures were incidence rate of Frey's syndrome assessed by participants (by questionnaire) and sweating area assessed by Minor's starch-iodine test. We used GRADE to assess the certainty of the evidence for each outcome. MAIN RESULTS We included three RCTs (124 participants), two of which we assessed as at high risk of bias and one at unclear risk of bias. All studies were hospital-based and recruited participants undergoing superficial parotidectomy. Most participants were diagnosed with benign lesions of the parotid gland. Participants were followed up for more than six months. The studies evaluated the two comparisons shown below:Sternocleidomastoid muscle flap versus no flapTwo studies assessed this comparison. Both assessed the effects of the sternocleidomastoid muscle flap procedure on the incidence rate of Frey's syndrome assessed clinically but neither showed a significant difference between groups (risk ratio (RR) 0.08, 95% confidence interval (CI) 0.00 to 1.23; 24 participants and RR 1.23, 95% CI 0.88 to 1.73; 36 participants; very low-certainty evidence). We did not pool the data due to the high heterogeneity (I² = 87%).One study found that the sternocleidomastoid muscle flap may result in little or no difference in other complications including haematoma (RR 2.18, 95% CI 0.09 to 50.16; 36 participants; low-certainty evidence), subjective painful or restricted cervical movement (RR 0.54, 95% CI 0.14 to 2.05; 36 participants; low-certainty evidence) and scar spread in the cervical region (RR 0.71, 95% CI 0.05 to 10.54; 36 participants; low-certainty evidence). Both studies reported the incidence rate of Frey's syndrome assessed by participants, with one reporting no events in either group and the other finding no evidence of a difference (RR 0.63, 95% CI 0.32 to 1.26; 36 participants; low-certainty evidence).Acellular dermal matrix versus no graftOnly one study assessed this comparison. Use of an acellular dermal matrix graft may result in little or no difference to the incidence rate of Frey's syndrome (assessed clinically) in comparison with the no graft group, but the evidence is very uncertain (RR 0.08, 95% CI 0.00 to 1.25; 30 participants; very low-certainty evidence).Acellular dermal matrix may slightly increase the wound infection rate compared with control (RR 17.00, 95% CI 1.02 to 282.67; 64 participants; low-certainty evidence). Acellular dermal matrix may result in little or no difference to the incidence of seromas or sialoceles (RR 2.33, 95% CI 0.66 to 8.23; 64 participants; low-certainty evidence). Acellular dermal matrix may result in little or no difference to the incidence rate of Frey's syndrome (assessed by participants) in comparison with the no graft group (RR 0.33, 95% CI 0.04 to 3.04; 64 participants; low-certainty evidence). AUTHORS' CONCLUSIONS The evidence for the effectiveness of graft interposition in preventing Frey's syndrome is of low or very low certainty. The use of acellular dermal matrix may be associated with an increase in the wound infection rate, and little or no difference in the incidence of seromas or sialoceles. Further studies are needed to draw reliable conclusions.

Abstract
PURPOSE OF REVIEW Food allergy symptoms may involve a wide variety of organs (skin, gastrointestinal tract, and eyes) and systems (respiratory, circulatory, and neurological). They are often associated. Their severity ranges from mild to potentially life-threatening reactions and the presentation from acute to chronic. RECENT FINDINGS Food allergies have been the focus of multiple studies, position papers, and guidelines in recent years. They have defined an approach in classifying symptoms as mild to anaphylactic, distinguishing objective from subjective symptoms, and describing their heterogeneity, specific phenotypes or syndromes (e.g., lipid transfer protein syndrome or pollen food syndrome). Cofactors can also influence food allergy reactions. Symptoms of non-IgE-gastrointestinal food allergies, illustrated by eosinophilic esophagitis and food-protein-induced enterocolitis syndrome, are also now better understood and defined. Improvement in the knowledge of food allergy symptoms is crucial for correct diagnosis and a personalized treatment approach. SUMMARY Through a better description and understanding of symptoms, the diversity of food allergies is now better known. The next step is to harmonize symptom assessment not only for clinicians but also for patients, researchers, and public health stakeholders, to describe food allergy phenotypes and their underlying mechanisms and endotypes, to develop targeted management.

Abstract
PURPOSE This study aimed to investigate the feasibility of adopting the ThormalGEN surgical patch (a porcine decellularized pericardial patch) in the superficial parotidectomy to prevent postoperative Frey's syndrome in patients with benign parotid tumor. MATERIALS AND METHODS A total of 59 patients with benign parotid tumor undergoing superficial parotidectomy between April 2016 and January 2017 were enrolled, and divided into the ThormalGEN group (n = 37) and the control group (n = 22) based on their willingness to have the ThormalGEN surgical patch used in the superficial parotidectomy. At 6 months postoperation, the incidences of postoperative complications and Frey's syndrome were assessed by subjective assessment (patient self-assessment) and objective assessment (starch-iodine test), respectively. The risk factor of Frey's syndrome was analyzed by the multivariate logistic regression model. RESULTS The starch-iodine test, for objective assessment, showed that the ThormalGEN group had a significantly lower incidence of Frey's syndrome than the control group (8.11% vs. 40.91%, p = 006). However, in the patient self-assessment, there was no significant difference in the incidence of Frey's syndrome between groups (8.11% [3/37] vs. 13.64% [3/22], p = 0.4968). The incidences of postoperative complications were not significantly different between group (all p > 0.05). Two patients (5.41%) in the ThormalGEN group had salivary fistula. Multivariate logistic regression analysis showed that the ThormalGEN group had a significantly lower risk of Frey's syndrome than the control group (odds ratio = 0.11, 95% confidence interval = 0.02-0.51, p < 0.01). CONCLUSION These results suggest that the ThormalGEN surgical patch can effectively reduce the incidence of Frey's syndrome following superficial parotidectomy in patients with benign parotid tumor, and that this patch has a good safety and biocompatibility profile.
