The aim of this prospective study was to evaluate the incidence of allergic reactions to drugs compared to other kinds of medical emergencies admitted to the main Hospital in Milan during a 6 months period. At the same time we drew a list of drugs most frequently involved in allergic reactions, and a list of the most frequent symptoms. Using special forms, the medical staff collected patients' data: age, history of atopy, identification of the drug causing the reaction, and any previous reactions. Among 11,407 cases of medical emergencies, we found 163 (1.43%) patients showing drug reactions: the mean age was 27.3; 58.90% were female; atopy was present in 16.56%. The drugs most frequently involved were: pyrazon group (22%); ASA (20.86%); penicillin and derivatives (9.20%); sulfa drugs (6.14%); group B vitamins (4.30%); tetanus toxoid (4.30%); hyposensitizing extracts (3.68%); propionic acid derivatives (2.46%); paracetamol (1.84%); indomethacin (1.23%); rifampicin (1.23%); erythromycin (1.23%); glafenine (1.23%); others (17.80%). Urticaria and/or angioedema were the most frequent symptoms (86.51%), then anaphylactic shock (9.81%) and asthma (3.68%) with regard to anaphylactic shock only 6.20% of the patients had had a previous reaction to the same drug. From these data we can see that the incidence of drug reactions is very low compared to other medical emergencies; penicillin evidenced fewer reactions than expected, while the pyrazon group and ASA confirmed the data from literature.

Ibuprofen is 2-(4-isobutyl-fenyl)-propionic acid, which belongs to the same group of nonsteroidal antiinflammatory drugs (NSAIDs) as naproxen and ketoprofen. We present two instances of adverse reaction to pediatric ibuprofen, an acute urticaria and a fixed drug eruption, with tolerance to acetylsalicylic acid (ASA) and acetaminophen, in what seems to be hypersensitivity to the propionic acid group. Although these reactions are very rare and ibuprofen is still very safe, we think it is important to know about the possible side effects in order to recognize and treat them when they occur.

Adverse reactions to drugs are a frequent cause of morbidity and medical consultation; it is no surprise that nonsteroidal anti-inflammatory drugs (NSAIDs) run second, after antibiotics, mainly of the beta-lactam group (penicillins and cephalosporins). Numerous clinical pictures involving the skin--various morbilliform rashes, urticaria and angioedema as the most common--due to hypersensitivity to a particular NSAID (i.e., ibuprofen) have been described; other clinically defined skin diseases such as vasculitis, Steven-Johnson's syndrome, photosensitivity, fixed drug eruptions, livedo-like dermatitis, linear drug eruption, lichenoid drug eruption, exanthematous pustulosis, eczematous eruption, contact dermatitis and pemphigoid have received the attention of physicians. Extensive use around the world makes it interesting to investigate adverse cutaneous reactions to ibuprofen and other members of the propionic acid derivative group, to ascertain their prevalence, clinical presentation and prevention. This paper presents a review of published literature concerning cutaneous hypersensitivity reactions to ibuprofen and related arylpropionic acids.

The honey bee, which lives in the crowded environment of a social hive, is vulnerable to disease infection and spread. Despite efforts to develop various diagnostic methods, American foulbrood (AFB) caused by Paenibacillus larvae infection has caused enormous damage to the apicultural industry. Here, we investigated the volatile organic compounds derived from AFB. After inoculation of the AFB pathogen in honey bee larvae under lab conditions, we identified propionic acid, valeric acid, and 2-nonanone as volatile disease markers (VDMs) of AFB infection using GC/MS. Electrophysiological recordings demonstrated that middle-aged bees, the hygienic-aged bees, are more sensitive to these VDMs than the foragers. Thus, these VDMs have the potential to be efficient and significant cues for worker detection of AFB infected larvae in bee hives. This study supports the idea that the specific olfactory sensitivity of different worker bees depends on their tasks. Taken together, our finding is crucial and sufficient to develop novel disease volatile markers associated with honey bee diseases to diagnose and study the molecular and neural correlates of given hygienic behavior detecting these volatile chemicals by honey bees.
