Sustained Unresponsiveness (SU) to Cashew Nut Protein Following Oral Allergen-Specific Immunotherapy
This study is a long-term follow-up of participants from the randomized controlled trial (RCT) "Efficacy of Cashew Nut Protein Immunotherapy: A Protocol of a Single-Center Randomized Controlled Trial in the Pediatric Population", NCT06328504. At the end of the original RCT all participants will undergo an open Oral Food Challenge (OFC) to assess desensitization after 3 months on the maintenance dose of OIT. Patients who have completed the first part of the study will be invited to the current part of the project: - First arm (initial experimental group) - patients will continue oral immunotherapy (OIT) with cashew nut protein (1200mg) for the next 8 months (+/- 3...

Sustained Unresponsiveness (SU) to Sesame Protein Following Low-dose Oral Allergen-specific Immunotherapy
This study is a long-term follow-up of participants from the randomized controlled trial (RCT) "Efficacy and Safety of Low-Dose Sesame Oral Immunotherapy in Pediatric Patients", NCT06261554. At the end of the original RCT all participants will undergo an open Oral Food Challenge (OFC) to assess desensitization after 3 months on the maintenance dose of OIT. Patients who have completed the first part of the study will be invited to the current part of the project: - First arm (initial experimental group) - patients will continue oral immunotherapy (OIT) with low dose of sesame protein (300mg) for the next 8 months (+/- 3 weeks). - Second arm (initial control group -...

Testing the Addition of Chemotherapy or Chemo-Immunotherapy to the Usual Surgery for Advanced Head and Neck Cancer
This phase II trial tests the addition of chemotherapy, with carboplatin and paclitaxel, or chemo-immunotherapy, with carboplatin, paclitaxel and cemiplimab to standard salvage surgery followed by post operative radiation therapy and cisplatin for high risk patients, for the treatment of patients with PD-L1 positive head and neck squamous cell carcinoma that has come back and spread to nearby tissue or lymph nodes after a period of improvement (locally recurrent) or is persistent. Carboplatin is in a class of medications known as platinum-containing compounds. It works in a way similar to the anticancer drug cisplatin, but may be better tolerated than cisplatin. Carboplatin...

Trans-Cervical and Trans-abdominal Ultrasound for Monitoring Esophageal Thickness in Eosinophilic Esophagitis
Eosinophilic Esophagitis (EoE) is a chronic inflammatory disease characterized by eosinophilic infiltration of the esophageal mucosa, leading to symptoms of dysphagia and food impaction. Currently, upper endoscopy with biopsy is the gold standard for diagnosis and disease monitoring, but it is invasive, costly, and associated with procedural risks. The investigators want to use ultrasound imaging as a non-invasive assessment of esophageal wall thickness as a surrogate marker for mucosal inflammation. Participants will undergo ultrasound assessment at the same day of endoscopy, and than after 3-6 months (optional). The correlation between US-measured esophageal thickness...

Umbilical Cord Blood Therapy in a Child With Eosinophilic Duodenitis and Autism Spectrum Disorder: a Case Study
This single-case exploratory clinical study aims to evaluate the therapeutic potential of umbilical cord blood (UCB) infusion in a pediatric patient diagnosed with both eosinophilic duodenitis (ED) and autism spectrum disorder (ASD). ED is a rare inflammatory gastrointestinal condition characterized by excessive eosinophil infiltration in the duodenal mucosa, often associated with immune hypersensitivity and allergic responses. ASD is a neurodevelopmental disorder marked by deficits in social interaction, communication, and behavioral flexibility. Recent evidence suggests a link between gastrointestinal inflammation and neurodevelopmental symptoms via the gut-brain axis,...

UNC Cashew Sublingual Immunotherapy
The CASCADES study will investigate the safety and efficacy of sublingual immunotherapy (SLIT) for the treatment of cashew allergy in children ages 1-11 years old. Primary efficacy will be assessed after 18 months of cashew SLIT. Lab studies and an oral food challenge after 6 months of cashew SLIT will help determine how quickly cashew SLIT begins to take effect.

Validation Of A Parent Administered Symptom Score For Unsettled Infants (Every Baby is UnIQue)
It's common for infants to be unsettled, especially in the first few months of life. While this is often normal, persistent symptoms can be stressful for families. Parents naturally seek explanations, and common suspected causes include colic, reflux, eczema, and cow's milk allergy (CMA). However, CMA is frequently over diagnosed, which can lead to unnecessary changes such as stopping breastfeeding or switching to expensive specialist formulas. To address this, we've developed an online questionnaire to help track and understand symptoms in unsettled infants. Our long-term goal is to use this tool to support more accurate diagnosis of CMA. Before that, we need to test and...
