Abstract
INTRODUCTION Potentially harmful excipients (PHEs) for children have been reported and the need for information collection has been advocated. However, studies on the actual occurrence of adverse events are limited. This study investigated the quantitative exposure of PHEs via injection and their association with adverse events in children under 2 years of age. MATERIALS AND METHODS As a single-center observational study, children aged 0-23 months received injectable drugs from April 1, 2018, to March 31, 2023 were included. Information on PHE exposure and adverse events after administration were extracted from medical records. Sodium benzoate, benzyl alcohol, ethanol, glycerol, lactose, polyethylene glycol paraben, polysorbate, propylene glycol, sorbitol, sucrose, sulfite, and thimerosal were selected as PHEs. RESULTS AND DISCUSSION 6265 cases, 333,694 prescriptions, and 368 drugs (264 ingredients) were analyzed. The median age was 0.63 years (interquartile range [IQR] 0.1-1.1). 72,133 prescriptions, 132 drugs and 99 ingredients contained PHE; 2,961 cases exposed to PHE and 1825 cases exceeding permitted daily exposure. The drug with the highest number of exposure cases was hydroxyzine, and the highest number of prescriptions was heparin (both drugs contain benzyl alcohol). In association between adverse events and PHE exposure, higher doses in cases of adverse event occurrence were found in benzyl alcohol, glycerol, polyethylene glycol, and polysorbate exposed cases. Among thimerosal-exposed cases, "developmental delay" was more frequent in exposed cases, but the causal relationship was unknown. Further investigation is needed to clarify the relationship between adverse events and PHE exposure. Additionally, more precise information on PDE for pediatrics including neonates is necessary.

Abstract
Although there is considerable literature pertaining to IgE and non IgE-mediated food allergy, there is a paucity of information on non-immune mediated reactions to foods, other than metabolic disorders such as lactose intolerance. Food additives and naturally occurring 'food chemicals' have long been reported as having the potential to provoke symptoms in those who are more sensitive to their effects. Diets low in 'food chemicals' gained prominence in the 1970s and 1980s, and their popularity remains, although the evidence of their efficacy is very limited. This review focuses on the available evidence for the role and likely adverse effects of both added and natural 'food chemicals' including benzoate, sulphite, monosodium glutamate, vaso-active or biogenic amines and salicylate. Studies assessing the efficacy of the restriction of these substances in the diet have mainly been undertaken in adults, but the paper will also touch on the use of such diets in children. The difficulty of reviewing the available evidence is that few of the studies have been controlled and, for many, considerable time has elapsed since their publication. Meanwhile dietary patterns and habits have changed hugely in the interim, so the conclusions may not be relevant for our current dietary norms. The conclusion of the review is that there may be some benefit in the removal of an additive or a group of foods high in natural food chemicals from the diet for a limited period for certain individuals, providing the diagnostic pathway is followed and the foods are reintroduced back into the diet to assess for the efficacy of removal. However diets involving the removal of multiple additives and food chemicals have the very great potential to lead to nutritional deficiency especially in the paediatric population. Any dietary intervention, whether for the purposes of diagnosis or management of food allergy or food intolerance, should be adapted to the individual's dietary habits and a suitably trained dietitian should ensure nutritional needs are met. Ultimately a healthy diet should be the aim for all patients presenting in the allergy clinic.

Abstract
Asthma is a chronic inflammatory airway disease that is commonly seen in the emergency department (ED). This article provides an evidence-based review of diagnosis and management of asthma. Early recognition of asthma exacerbations and initiation of treatment are essential. Treatment is dictated by the severity of the exacerbation. Treatment involves bronchodilators and corticosteroids. Other treatment modalities including magnesium, heliox, and noninvasive ventilator support are discussed. Safe disposition from the ED can be considered after stabilization of the exacerbation, response to treatment and attaining peak flow measures.

Abstract
AIMS To better understand the outcome of employing low electric current (LEC) technology as a new preservation and alternative in wine technology, and to contribute to its development. It is used in industrial-scale winemaking with commercial yeast (Saccharomyces cerevisiae) during the grape must fermentation. METHODS AND RESULTS LEC (200 mA, time 16 days) was applied to fresh grape must as an alternative method to the usual sulfur dioxide addition used in the industrial process; two tanks, each 30,000 l, were employed for parallel fermentations. The results show that LEC decreased the survival time and increased the death rate of apiculate yeasts, whereas it did not affect the growth and survival of S. cerevisiae. A comparison was made of the main chemical and sensory parameters of the wines obtained. CONCLUSIONS The results have demonstrated that the low-voltage treatment had a positive effect on the grape juice fermentation (yeast microflora) during the early stages of winemaking. SIGINIFICANCE AND IMPACT OF THE STUDY: These results could be of significant importance in developing, for 'biological wine', new winemaking technologies for an innovative control process of yeast fermentation.

Abstract
Food allergies represent an important health problem in industrialized countries. Undeclared allergens as contaminants in food products pose a major risk for sensitized persons. A proposal to amend the European Food Labelling Directive requires that all ingredients intentionally added to food products will have to be included on the label. Reliable detection and quantification methods for food allergens are necessary to ensure compliance with food labelling and to improve consumer protection. Methods available so far are based on protein or DNA detection. This review presents an up-to-date picture of the characteristics of the major food allergens and collects published methods for the determination of food allergens or the presence of potentially allergenic constituents in food products. A summary of the current availability of commercial allergen detection kits is given. One part of the paper describes various methods that have been generally employed in the detection of allergens in food; their advantages and drawbacks are discussed in brief. The main part of this review, however, focuses on specific food allergens and appropriate methods for their detection in food products. Special emphasis is given to allergenic foods explicitly mentioned in the Amendment to the European Food Labelling Directive that pose a potential risk for allergic individuals, namely celery, cereals containing gluten (including wheat, rye and barley) crustaceans, eggs, fish, peanuts, soybeans, milk and dairy products, mustard, tree-nuts, sesame seeds, and sulphite at concentrations of at least 10 mg kg(-1). Sulphites, however, are not discussed.

Abstract
OBJECTIVE To investigate the possibility that inhalation of raspberry powder at work can cause occupational asthma. METHODS We report the case of a 35-year-old, nonsmoking woman who complained of hay fever symptoms, wheezing, and shortness of breath two or three times a month exclusively in association with coating chewing gum with raspberry powder. Prick test extracts with the five types of fruit powder were produced. Peak expiratory flow rate monitoring five times daily was performed for an 8-week period while the patient was at work. Specific IgE and histamine release tests for raspberry powder were performed. Breathing zone dust measurements were taken. RESULTS Baseline lung function and histamine provocation test results were normal. During the 8-week monitoring period, 5 episodes of reduced peak expiratory flow rate were demonstrated. Each period was directly related to working with raspberry powder. A 9-mm prick test result positive for raspberry powder was seen (histamine control, 9 mm). In addition, the result of a radioallergosorbent test for raspberry was positive (0.84 kUA/L). The result of a histamine release test with raspberry powder from work was negative. Breathing zone total dust measurement was 5.9 mg/m3. CONCLUSIONS To our knowledge, this is the first description of occupational asthma due to the inhalation of raspberry powder. The symptoms of the patient described herein disappeared after she was moved to another part of the factory. Hygienic improvements were performed at the workplace to reduce the sensitization risk of other workers.

Abstract
The role of food intolerance in asthma is well recognized, and where food avoidance measures are instituted considerable improvement in asthma symptoms and in reduction in drug therapy and hospital admissions can result. These benefits may have a greater impact in those patients with greater symptoms. However, the promise of such benefits should not result in an approach which ignores inhaled drug therapy, or in a dietary regime which is inappropriate in the face of mild symptoms. Whilst sub-optimal intake of dietary nutrients is also a recently recognized potential risk factor for asthma, available data are insufficient to implicate any as casual. A number of studies have sought to establish the role of the antioxidant vitamins, A, C and E and selenium, yet others of the elements sodium and magnesium. Sub-optimal nutrient intake may enhance asthmatic inflammation, consequently contributing to bronchial hyperreactivity. Prospective studies of supplementation therapy are needed to confirm this.

Abstract
Atopy predisposes an individual to the development of asthma, whereby specific triggers may repeatedly cause acute exacerbations and contribute to chronic inflammation. This IgE-mediated response to common allergens is the strongest predisposing factor for developing asthma. Airway inflammation involves release of immunological mediators via T lymphocyte dependent, and IgE dependent and independent mechanisms which attract inflammatory cells from the circulation. The role of the eicosanoids as pivotal mediators in promoting some of the changes in asthma has only recently been fully explored. Inflammatory reactions result when mediators and cytokines released from resident and infiltrating cells interact. This interaction also contributes to the bronchoconstriction, hypersecretion, and mucosal edema in the airways.

Abstract
Endogenous sulfite is generated as a consequence of the body's normal processing of sulfur-containing amino acids. Sulfites occur as a consequence of fermentation and also occur naturally in a number of foods and beverages. As food additives, sulfiting agents were first used in 1664 and approved in the United States as long ago as the 1800s. With such long experience with their use, it is easy to understand why these substances have been regarded as safe. They are currently used for a variety of preservative properties, including controlling microbial growth, preventing browning and spoilage, and bleaching some foods. It is estimated that up to 500,000 (< .05% of the population) sulfite-sensitive individuals live in the United States. Sulfite sensitivity occurs most often in asthmatic adults--predominantly women; it is uncommonly reported in preschool children. Adverse reactions to sulfites in nonasthmatics are extremely rare. Asthmatics who are steroid-dependent or who have a higher degree of airway hyperreactivity may be at greater risk of experiencing a reaction to sulfite-containing foods. Even within this limited population, sulfite sensitivity reactions vary widely, ranging from no reaction to severe. The majority of reactions are mild. These manifestations may include dermatologic, respiratory, or gastrointestinal signs and symptoms. Severe nonspecific signs and symptoms occur less commonly. Broncho-constriction is the most common sensitivity response in asthmatics. The precise mechanisms of the sensitivity responses have not been completely elucidated. Inhalation of sulfur dioxide (SO2) generated in the stomach following ingestion of sulfite-containing foods or beverages, a deficiency in a mitochondrial enzyme, and an IgE-mediated immune response have all been implicated.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
This discussion of asthma management should be regarded as providing guidelines, not dogma. The underlying principles of asthma management include recognition of the variability of the disease and the importance of the underlying inflammatory condition. Clinical assessment is not enough and objective monitoring with PEFR or spirometry provides important data. The treatment protocols require individualization. It is important that the patient and family are team members working together with the medical staff toward a goal of good asthma management. In the discussion of the management of asthma, much emphasis was placed on spirometry and home measurement of PEFR. Office use of spirometry is now the norm for asthma management. Providing asthmatic patients with peak flow meters and instructions in their use is part of the routine care of asthma. Instruction of the patient and family in the proper use of medications is paramount. The MDI devices need to be prescribed with careful instructions regarding their use. When the patient comes in for follow-up, part of the examination should include the patient's demonstration of how he uses this device. Discussion of the proper and safe use of bronchodilators is important. Overuse of inhaled bronchodilators may be a reflection of increasing asthma or, at the very least, evidence that the patient does not understand appropriate treatment of asthma. If a patient is dependent on regular use of an inhaled beta agent, it is likely that he would benefit from therapy directed at the underlying inflammation of asthma. The patient and the family should understand the purpose of each medication, the side effects, and the risks and benefits of their use. In particular, if steroid medications are necessary, the reasons for their use should be explained. Carefully matching the severity of the asthma with the therapeutic protocols provides an organized approach to asthma treatment. Avoiding triggers of asthma and controlling the environmental exposure to potential triggers leads to lower medication requirements and less lability. Offering the family written instructions to cope with changes in the child's condition, based on assessment of clinical and PEFR observations, allows them more autonomy and comfort in the day-to-day care of the asthmatic child.

Abstract
Forty samples of fresh and fried burgers were analysed. A habitual use and often abuse of sulphites was detected. In the case of the uncooked samples, 62.5% contained residual levels of total SO2 above 450 micrograms/g. The frying process was found to lead to a mean reduction of 36.8 +/- 11.1% in the case of free sulphite and of 40.9 +/- 12.6% for total sulphite. This reduction was independent of the concentration of sulphite present and did not seem to be related to the type of meat used. Most burgers cooked in restaurants were found to contain sulphites, sometimes at elevated levels. The HPLC analytical method for the determination of sulphite contents in burgers, previously applied to fresh sausages, was compared with the optimized Monier-Williams method. The results obtained with both methods in the determination of total SO2 were found to have the same precision although there were significant differences in the contents of additive (p < 0.05).
