During the period from September 8 to October 2, 1970, 44 of the 120 children and 78 of 141 adults questioned at the Children's Asthma Research Institute and Hospital experienced gastroenteritis characterized by nausea, vomiting, and fever and/or chills. Diarrhea was rare in children (4.5%) and common in adults (74%). The median duration of illness for children, 18 hours, was significantly shorter than the 48 hours for adults. All viral and bacterial cultures of 30 stool specimens were negative for viruses and bacterial pathogens. A retrospective survey of 28 ill employees revealed a secondary attach rate of 46% of 76 family contacts. A bacteria-free filtrate prepared from stool swab specimens of 2 ill adults by a team at the National Institute of Allergy and Infectious Diseases was administered orally to 3 adult volunteers. One of the 3 vomited and had 4 watery diarrheal stools on the third post-inoculation day. Diarrheal stool filtrates from this person were then given orally to 8 others; 1 became ill. Although the epidemiologic features point to the respiratory route of infection, the probably successful serial transmission of disease via bacteria-free stool filtrates through 2 generations of volunteers also suggests that the "Denver agent" is a virus-sized particle that replicates in the gastrointestinal tract.

Listeria monocytogenes causes sepsis and meningitis in immunocompromised hosts and a devastating maternal/fetal infection in pregnant women. In recent years a more benign gastroenteritis in normal hosts has been described. Listeria has been increasingly identified as a food-borne pathogen, and large-scale contamination of processed foods with resulting outbreaks has occurred in recent years, possibly as a result of consolidation of the food industry. Experimental listeriosis in mice has proven to be an extraordinarily useful model for analyzing cell-mediated immune host defenses. Contrary to original concepts, we found that neutrophils, not macrophages, are the prime effectors during early infection. CD8+ T cells are then responsible for lysing infected hepatocytes through perforin-related (early primary and secondary infection) or Fas-L/Fas mechanism (late primary). Of interest, non-classical MHC class Ib restricted recognition mechanisms exist early, whereas MHC class Ia mechanisms can be detected throughout infection.

In order to determine the prevalence of childhood allergic diseases, infectious diseases, and the relationship between them, 8723 children from three junior high schools in Tou-Cheng City, Taipei County, were studied using questionnaires developed according to the International Study of Asthma and Allergies in Childhood (ISAAC) criteria combined with supplementary questions about infectious diseases. Students and their parents completed the questionnaires at home. The age of the children ranged from 10 to 18 years old (14.12 +/- 0.89 years), the majority (96.03%) was aged from 13 to 15 years old. The 12-month prevalences of self-reported allergic disease symptoms were: asthma symptom 8.2%, allergic rhinitis symptom 39.6%, and atopic dermatitis symptom 5.9%. The prevalences of diagnosis of the allergic diseases were: asthma 8.7%, allergic rhinitis 24.1%, and atopic dermatitis 3.9%. The 12-month prevalences of diagnosis of infectious diseases were: pneumonia 0.6%, bronchitis 7.2%, sinusitis 7.2%, purulent conjunctivitis 2.5%, otitis media 4.3%, encephalitis or meningitis 0.4%, gastroenteritis 14.5%, acne 23.9%, purulent dermatitis 1.3%, and other infectious diseases 1.2%. Lifetime admission rates of children due to infectious diseases were: pneumonia 1%, bronchitis 1.8%, sinusitis 0.3%, purulent conjunctivitis 0.2%, otitis media 0.3%, encephalitis or meningitis 0.3%, gastroenteritis 2.1%, and other infectious diseases 0.6%. The prevalence of infectious diseases was significantly higher in children with allergic disease symptoms (defined as asthma, allergic rhinitis, or atopic dermatitis). These results demonstrated the presence of a link between allergic diseases and infectious diseases, which may have some important clinical implications.

Seafood, including fish, shrimp, lobster, crab, crayfish, mussel, and clam are among the most frequent causes of food allergy. Seafood poisoning, including reactions to natural toxins, frequently masquerades as an allergic reaction on presentation. Ingestion of contaminated shellfish results in a wide variety of symptoms, depending on the toxins present, their concentrations in the shellfish, and the amount of contaminated shellfish consumed. Five types of shellfish poisoning have been identified clearly including paralytic, neurotoxic, diarrhetic, amnestic, and azaspiracid shellfish poisonings. Based on the presence or absence of the toxin at the time of capture, fish poisoning can be considered conceptually in two categories. In ciguatera and puffer fish poisoning, the toxin is present in live fish, whereas in scombroid, it is produced only after capture, in the fish flesh, by contaminating bacteria because of improper refrigeration. Most shellfish-associated illness is infectious in nature (bacterial or viral), with the Norwalk virus accounting for most cases of gastroenteritis.

There are more than 40 H(1)-antihistamines available worldwide. Most of these medications have never been optimally studied in prospective, randomized, double-masked, placebo-controlled trials in children. The aim was to perform a long-term study of levocetirizine safety in young atopic children. In the randomized, double-masked Early Prevention of Asthma in Atopic Children Study, 510 atopic children who were age 12-24 months at entry received either levocetirizine 0.125 mg/kg or placebo twice daily for 18 months. Safety was assessed by: reporting of adverse events, numbers of children discontinuing the study because of adverse events, height and body mass measurements, assessment of developmental milestones, and hematology and biochemistry tests. The population evaluated for safety consisted of 255 children given levocetirizine and 255 children given placebo. The treatment groups were similar demographically, and with regard to number of children with: one or more adverse events (levocetirizine, 96.9%; placebo, 95.7%); serious adverse events (levocetirizine, 12.2%; placebo, 14.5%); medication-attributed adverse events (levocetirizine, 5.1%; placebo, 6.3%); and adverse events that led to permanent discontinuation of study medication (levocetirizine, 2.0%; placebo, 1.2%). The most frequent adverse events related to: upper respiratory tract infections, transient gastroenteritis symptoms, or exacerbations of allergic diseases. There were no significant differences between the treatment groups in height, mass, attainment of developmental milestones, and hematology and biochemistry tests. The long-term safety of levocetirizine has been confirmed in young atopic children.

Weekly (August 2003-December 2008) numbers of five common paediatric diseases and the incidence of respiratory viruses were obtained from a children's hospital in Singapore and correlated with climate data using multivariate time-series techniques. Upper respiratory tract infections were positively correlated with the incidences of influenza A, B, respiratory syncytial virus (RSV) and parainfluenza viruses (types 1-3 combined). Lower respiratory tract infections were positively correlated with only the incidence of RSV. Both upper and lower respiratory tract infections were negatively correlated with relative humidity. Asthma admissions were negatively correlated with maximum temperature and positively correlated with the incidence of influenza B and increasing hours of sunshine. Although sporadic cases of adenovirus infection were identified, not enough cases were available for a more detailed analysis. Gastroenteritis and urinary tract infections, included as control diseases, were not correlated significantly with any climate parameters. These correlations are compatible with current understanding of respiratory virus survival under certain climate conditions and may assist the prediction of disease burdens and hospital resource planning in such tropical environments.

Wheat-dependent exercise-induced anaphylaxis (WDEIA) usually occurs 1 to 4 hours after wheat ingestion and the pathophysiology of WDEIA remains unknown. It is recommended that WDEIA patients refrain from exercise for 4 to 6 hours after wheat ingestion. We report a case of a 51-year-old man who experienced 5 anaphylaxis attacks; two of which occurred 10 to 24 hours after wheat ingestion and exercise. He has a history of chronic gastroenteritis that responds well to antihistamine drugs but not proton pump inhibitors (PPIs) and prokinetic agents. Abdominal CT results implied the possibility of superior mesenteric artery syndrome. We suggest that WDEIA occurs 6 hours after wheat ingestion in cases compounded by obstructive gastrointestinal diseases.
