DiGeorge syndrome (DGS) is a primary immunodeficiency characterized by various degrees of T-cell deficiency. In partial DGS (pDGS), other risk factors could predispose to recurrent infections, autoimmunity, and allergy. The aim of this study was to assess the effect of different factors in the development of infections, autoimmunity, and/or allergy in patients with pDGS. We studied 467 pDGS patients in follow-up at Great Ormond Street Hospital. Using a multivariate approach, we observed that palatal anomalies represent a risk factor for the development of recurrent otitis media with effusion. Gastroesophageal reflux/dyspha...

In this study, we enumerated and compared T lymphocytes and Tregs in esophageal tissue of patients with EoE, gastroesophageal reflux disease (GERD) and normal controls. METHODS: Ten patients with EoE, ten patients with GERD and eight normal controls were included. Immunohistochemistry staining was used to enumerate T lymphocytes and Tregs. CD3+ cells were considered as T cells and FOXP3+, CD3+ cells were considered as Tregs. T cells and Tregs were counted in 10 high power fields (HPF) (×400) for each patient and the average of 10 HPFs was recorded. RESULTS: The mean±SEM of Tregs in esophageal tissue ...

During the 20th century, medicine became very good at compartmentalizing different systems of the body in order to understand them better. However, today we are increasingly realizing that different systems of the body are interconnected and cannot be completely understood in isolation. The brain-gut connection is one very important example of this phenomenon. Anatomy of the brain-gut connection What exactly is the connection between brain and gut? The brain sends signals to the digestive, or gastrointestinal (GI), tract via the sympathetic (“fight or flight”) nervous system and the parasympathetic (“rest...

BackgroundThe purpose of this study was to evaluate the relations between gastroesophageal reflux disease (GERD) and chronic rhinosinusitus (CRS) in a Korean population.MethodsSubjects from the Korean National Health Insurance Service ‒National Sample Cohort, all ≥20 years old, were assessed from 2002 to 2013. In total, 23,489 CRS participants were matched with 93,956 controls at a ratio of 1:4 with respect to age, group, sex, income group, region of residence, hypertension, diabetes, and dyslipidemia. We analyzed previous hi story of GERD in the CRS and control groups. The CRS group included patients identified using...

It’s hardly news that the gastrointestinal tract is important to human health: It transports food from the mouth to the stomach, converts it into absorbable nutrients and stored energy, and shuttles waste back out of the body. If you don’t properly nourish yourself, you don’t live. It’s that simple. But in recent years, scientists have discovered that the GI system has an even bigger, more complex job than previously appreciated. It’s been linked to numerous aspects of health that have seemingly nothing to do with digestion, from immunity to emotional stress to chronic illnesses, including can...

AbstractAllergic eosinophilic esophagitis (EoE) is a chronic, allergen-mediated inflammatory disease of the esophagus, and the most common cause of prolonged dysphagia in children and young adults in the developed world. While initially undistinguished from gastroesophageal reflux disease-associated esophageal eosinophilia, EoE is now recognized as a clinically distinct entity that shares fundamental inflammatory features of other allergic conditions and is similarly increasing in incidence and prevalence. The clinical and epidemiologic associations between EoE and other allergic manifestations are well established. In add...

Discussion Respiratory problems in infants can caused by many things including any type of obstruction from the nose to lung. Neonates and infants are particularly susceptible to changes in the size of the airway because of the physics of airflow resistance. Important reminders about infant airways: Resistance = 1/radius4 (Poiseuille’s equation) therefore even a 1 mm decrease in the airway circumferences increases the airflow resistance x16. Increased airflow causes less pressure along the walls, which can lead to collapse of the walls (Bernoulli’s and Venturi effects). Neonates have smaller lungs relative to ...

Abstract Eosinophilic esophagitis (EoE) is a multifactorial esophageal inflammation, with a genetic predisposition, which combines a deficient esophageal mucosal barrier, an abnormal immune reaction to environmental allergens mediated by Th2 interleukins, immediate esophageal lesions and dysmotility, with secondary remodeling and fibrosis. Symptoms include reflux, abdominal pain, and food impaction, with a variation according to age. Fibroscopy shows major and minor endoscopic and histologic criteria, with a mucosal count≥15 eosinophils/high power field (Eo/hpf). A new entity has been defined, where gastroesoph...

Grains can play havoc with your skin. The prolamin proteins, such as gliadin,  trigger autoimmune skin reactions and turn antibodies against the skin enzymes, their lectins fan the fires of inflammation, their proteins provoke allergies, and their amylopectins send blood sugar and insulin sky-high and provoke the skin-disrupting hormone insulin-like growth factor-1 (IGF). The whole grain package adds up to an impressive collection of skin conditions that can take a variety of forms, from simple red, itchy rashes to scaly, oily raised patches to large vesicles to gangrene. B...
