Review article: intestinal lymphoid nodular hyperplasia in children - the relationship to food hypersensitivity.
2012
SummaryBackground Lymphoid aggregates are normally found throughout the small and large intestine. Known as lymphoid nodular hyperplasia (LNH), these aggregates are observed especially in young children and are not associated with clinical symptoms being considered ‘physiological’. In children presenting with gastrointestinal symptoms the number and size of the lymphoid follicles are increased. Patients suffering from gastrointestinal symptoms (i.e. recurrent abdominal pain) should systematically undergo gastroduodenoscopy and colonoscopy. With these indications LNH, especially of the upper but also of the lower gastrointestinal tract has been diagnosed, and in some children it may reflect …

Calcium Pre-Rinse: Effect on permeability of dentin tubules by fluoride rinse
2019
Background The aim of this study was to evaluate whether calcium (CaL) solution would enhance the capacity of sodium fluoride (NaF) solution in reducing the permeability of hypersensitive dentin. Material and Methods Thirty-two Wistar rats ingested for 45 days acidic isotonic drink (Gatorade, pH 2.7) ad libitum to induce dental erosion. Then, molar teeth received a cold stimulus to confirm the presence and score the intensity of dentin hypersensitivity based on body contraction and noise. Animals were allocated to four groups (n=8), according to the solution(s) applied in the oral cavity: NaF (12 mmol/L, 1 min); CaL (150 mmol/L, 1 min); CaL followed by NaF (CaF+NaF, 1 min each); distilled w…
Allergic sensitization to common pets (cats/dogs) according to different possible modalities of exposure: an Italian Multicenter Study
2018
Abstract Background The query “are there animals at home?” is usually administered for collecting information on anamnesis. This modality to consider exposure to pet allergens constitutes a potential bias in epidemiological studies and in clinical practice. The aim of our study was to evaluate/quantify different modalities of exposure to cat/dog in inducing allergic sensitization. Methods Thirty Italian Allergy units participated in this study. Each centre was required to collect the data of at least 20 consecutive outpatients sensitized to cat/dog allergens. A standardized form reported all demographic data and a particular attention was paid in relieving possible modalities of exposure to…
SIRM-SIAAIC consensus, an Italian document on management of patients at risk of hypersensitivity reactions to contrast media
2020
Abstract Hypersensitivity reactions (HRs) to contrast media (CM) can be distinguished in immune-mediated (including allergic reactions) and non-immune-mediated reactions, even if clinical manifestations could be similar. Such manifestations range from mild skin eruptions to severe anaphylaxis, making it important for radiologists to know how to identify and manage them. A panel of experts from the Società Italiana di Radiologia Medica e Interventistica (SIRM) and the Società Italiana di Allergologia, Asma e Immunologia Clinica (SIAAIC) provided a consensus document on the management of patients who must undergo radiological investigations with CM. Consensus topics included: the risk stratif…
Monitoring the quality of the hospital pharmacoterapeutic process by sentinel patient program
2018
To analyze the results of sentinel patient program to monitoring the quality pharmacoterapeutic process in the hospitalized patient through medication errors.Design: Observational, prospective and transversal study. Ambit: General hospital of 1,000 beds.From May 2011 to June 2016. Sample: Patients with treatment prescribe within 24 hours of being admitted with 4 or more medications.Medication error, drugs prescribed, medications and doses dispensing, drugs administered. Safety indicators were defined based on medication errors at each stage of the pharmacotherapeutic process.Of the 746 patients studied, 334 had at least 1 medication error (44.8%; IC95%: 41.7-47.8). In the 746 treatm…
Attentional bias towards interpersonal aggression in depression – an eye movement study
2020
Depressed individuals exhibit an attentional bias towards mood-congruent stimuli, yet evidence for biased processing of threat-related information in human interaction remains scarce. Here, we tested whether an attentional bias towards interpersonally aggressive pictures over interpersonally neutral pictures could be observed to a greater extent in depressed participants than in control participants. Eye movements were recorded while the participants freely viewed visually matched interpersonally aggressive and neutral pictures, which were presented in pairs. Across the groups, participants spent more time looking at neutral pictures than at aggressive pictures, probably reflecting avoidanc…
Review article: Chronic constipation and food hypersensitivity--an intriguing relationship.
2006
Summary Background Chronic constipation is common in the general population. Some studies have shown that in children cow's milk protein hypersensitivity can cause chronic constipation unresponsive to laxative treatment. Aims To review the literature and summarize the data that point to a relationship between refractory chronic constipation and food hypersensitivity, and to discuss the hypothesis that the pathogenesis of constipation due to food hypersensitivity. Methods A search in the U.S. National Library of Medicine was performed, matching the key words ‘chronic constipation, food intolerance and allergy’. Results Thirty-three papers were found but only 19 of them were related to the to…
Feasibility of the Allergy Questionnaire for Athletes (AQUA © ) in pediatric age
2018
A burden of respiratory and allergic symptoms up to almost 60% has been observed in young and adult athletes, influencing physical performances1 . The Allergy Questionnaire for Athletes (AQUA©) is a validated screening tool for the prediction of the atopic status in adult athletes2 ; it was recently tested in Belgian young elite athletes (12-14 years old)3 , but its actual feasibility and suitability for children and adolescent was not evaluated. Indeed, there is evidence that children are prone to employ "satisficing" response strategies, answering every question positively/negatively, or simply not answering4 . Therefore, the present cross-sectional survey was carried out to assess feasib…
