Eosinophilic gastroenteritis is a rare inflammatory disorder of the gastrointestinal tract. Although commonly associated with allergic diseases, it is also rarely associated with autoimmune disorders. This case report describes a 17-year-old Filipino male with eosinophilic gastroenteritis, manifesting as abdominal pain, vomiting and diarrhoea. He had no allergic diseases, but he was previously diagnosed with chronic bullous disease. His symptoms improved with the initiation of corticosteroids. To date, this is the first case report of a patient with eosinophilic gastroenteritis and chronic bullous disease.

Introduction Allergic rhinitis is a common disease entity that may be easily misdiagnosed and mistreated. It is a global concern, affecting 10% to 25% of the population worldwide, that has to be controlled since it can be disabling affecting the quality of life of patients. The Philippine Society of OtolaryngologyHead and Neck Surgery is currently updating its 2006 guideline on Allergic Rhinitis. The Section of Rhinology, Department of Otorhinolaryngology together with the Section of Allergy and Immunology, Departments of Pediatrics and Internal Medicine, came up with practice parameters in the diagnosis and management of adult and pediatric patients suspected to have allergic rhinitis to guide clinicians in managing these patients. Locally, it is the first collaboration of otorhinolaryngologists and allergists. Scope of the Guideline This practice parameter was developed to guide general physicians, otorhinolaryngologists and allergists in the diagnosis and management of adult and ...

Background: There has been no documented data on the prevalence of allergic rhinitis among Filipino adults. Objective: The objective of this study is to determine the prevalence of allergic rhinitis among adults in the Philippines. Methods: Using a multi-staged cluster sampling methodology, this study evaluated 7,202 adults from 3,744 households, 79 provinces and 17 regions. A pre-validated written questionnaire for allergic rhinitis based on the International Study of Asthma and Allergies of Childhood was used as the survey instrument. Results: The response rate obtained from the interview was 94.1%. The overall prevalence of nose symptoms in the past 12 months was 20 % while prevalence of nose symptoms at any time in the past was 23.8%. The proportion among both sexes was similar. The prevalence was highest among the respondents 40-49 years old. The overall prevalence of nose and eye symptoms for the past twelve months was 14.0%. The prevalence of respondents who reported presence of nose problems for the past twelve months was similar across the 12 months of the year with highest rates noted in the months of June and May. Respondents from the rural area (22.1%) reported a higher prevalence of nose symptoms for the past twelve months compared to respondents from urban area (18%). There was no significant difference in prevalence of nose symptoms among residents living in coastal and/or inland areas. Conclusion: The overall prevalence of allergic rhinitis in the Philippines based on the 2008 National Nutrition and Health Survey is 20.0%.
