Eosinophilic gastroenteritis (EGE) is characterized by eosinophilic infiltration of the digestive organs, most commonly of the stomach and the duodenum. Symptoms of EGE are nonspecific and include nausea, vomiting, abdominal pain, dyspepsia, malabsorption, ascites and weight loss. The various symptoms of EGE depend on its location and the depth of gastrointestinal eosinophil infiltration. We report a case presenting with acute pancreatitis caused by a milk allergy. The patient's symptoms rapidly improved after treatment with corticosteroids, and he remained symptom-free for more than 20 months by the elimination of cow's milk from his diet. Serum titers of pancreatic enzymes and total bilirubin simultaneously recovered and blood eosinophil counts normalized. The causative allergens of EGE are too various to detect; however, allergologic exams revealed that a cow's milk allergy had provoked EGE in our case. Adult-onset cow's milk allergies are rare; when seen, however, they may present severe complications such as anaphylaxis, gastroenteritis and pancreatitis. When unaccountable gastrointestinal symptoms are observed, EGE caused by food allergies should be included in the differential diagnosis.

Indolent systemic mastocytosis (SM) patients have a varied clinical presentation, ranging from predominantly cutaneous symptoms to recurrent systemic symptoms (eg, flushing, palpitations, dyspepsia, diarrhea, bone pain) that can be severe and potentially life threatening (anaphylaxis). Mastocytosis patients without skin involvement pose a diagnostic challenge; a high index of suspicion is needed in those with mast cell-degranulation symptoms, including anaphylaxis following Hymenoptera stings or other triggers. Modern-era molecular and flow-cytometric diagnostic methods are very sensitive and can detect minimal involvement of bone marrow with atypical/clonal mast cells; in some cases, full diagnostic criteria for SM are not fulfilled. An important aspect of treatment is avoidance of known symptom triggers; other treatment principles include a stepwise escalation of antimediator therapies and consideration of cytoreductive therapies for those with treatment-refractory symptoms. The perioperative management of mastocytosis patients is nontrivial; a multidisciplinary preoperative assessment, adequate premedications, and close intra- and postoperative monitoring are critical. Smoldering mastocytosis is a variant with high systemic mast cell burden. While its clinical course can be variable, there is greater potential need for cytoreductive therapies (eg, interferon-alpha, cladribine) in this setting. A systematic approach to the diagnosis and treatment of indolent SM using a case-based approach of representative clinical scenarios is presented here.

Helicobacter pylori (H. pylori) is a Gram-negative spiral bacterium that is present in nearly half the world's population. It is the major cause of peptic ulcer disease and a recognized cause of gastric carcinoma. In addition, it is linked to non-ulcer dyspepsia, vitamin B12 deficiency, iron-deficient anemia and immune thrombocytopenic purpura. These conditions are indications for testing and treatment according to current guidelines. An additional indication according to the guidelines is "anyone with a fear of gastric cancer" which results in nearly every infected person being eligible for eradication treatment. There may be beneficial effects of H. pylori in humans, including protection from gastroesophageal reflux disease and esophageal adenocarcinoma. In addition, universal treatment will be extremely expensive (more than $32 billion in the United States), may expose the patients to adverse effects such as anaphylaxis and Clostridium difficile infection, as well as contributing to antibiotic resistance. There may also be an as yet uncertain effect on the fecal microbiome. There is a need for robust clinical data to assist in decision-making regarding treatment of H. pylori infection.

Alpha-gal allergy is a reaction where the immunoglobulin E antibody elicits a response to galactosealpha-1,3-galactose (alpha-gal) which is a mammalian oligosaccharide epitope found in nonprimate mammalian. After being exposed to a tick bite, particularly the Lone Star tick (Amblyomma americanum), an individual has been known to develop an alpha-gal allergy. Our patient presented with symptoms of delayed-onset allergy 3-8 hours after consuming mammalian meat products including beef and pork. These symptoms can include, but not limited to, the following: urticaria, angioedema, anaphylaxis, nausea, diarrhea, indigestion. Since symptoms do not present immediately, a delay in diagnosis can occur. Our patient highlights one of the few reported childhood cases with an alpha-gal allergy. We recommend a careful history, in particular, asking if the patient has a past history of tick bites and the appearance of allergy symptoms following beef or pork consumption. Keywords: allergy; food hypersensitivity; immunoglobulin E; meat products; tick bites.
