    ABSTRACT: Adverse reactions to local anesthetics (LA) are commonly reported in patients undergoing dental procedures and other minor surgical procedures. Most of these reactions, however, originate from psychosomatic, vasovagal or toxic conditions and are not immune-mediated. True immune-mediated reactions are considered extremely rare and are estimated to account for less than 1% of all adverse reactions to LA. On the other hand, almost all of the immune-mediated LA reactions that have been reported are related to adult patients. Here, however, we will present a pediatric case proven to be hypersensitive to two different amide-derivative LA's.

    ABSTRACT: The literature on the nature and prevalence of indoor and/or outdoor aeroallergens, atopy and symptoms of rhinitis and asthma in the Middle East region (defined here as Bahrain, Egypt, Iran, Iraq, Israel, Jordan, Kuwait, Lebanon, Oman, Palestine, Qatar, Kingdom of Saudi Arabia - KSA, Syria, United Arab Emirates and Yemen) was reviewed. Although documentation was poor in all countries other than Iran and the KSA, a wide range of "global" and "local" aeroallergens (grass, weed and tree pollens, fungal spores, insect allergens, dander, and house dust mites) has been observed across the region. The prevalence of current self-reported or parent-reported symptoms of rhinitis ranged from 9% to 38%. Researchers have suggested that the high atopy rates and self-reported rhinitis rates are associated with an on-going shift towards a "western" lifestyle.

    ABSTRACT: Acute Hemorrhagic Edema of Infancy is a small vessel leucocytoclastic vasculitis affecting young infants. It is characterized by large, target-like, macular to purpuric plaques predominantly affecting the face, ear lobes and extremities. Non-pitting edema of the distal extremities and low-grade fever may also be present. Extra-cutaneous involvement is very rare. Although the lesions have a dramatic onset in a twenty-four to forty-eight hour period, usually the child has a non-toxic appearance. In most cases there are no changes in laboratory parameters. The cutaneous biopsy reveals an inflammatory perivascular infiltrate. It is a benign and auto-limited disease, with complete resolution within two to three weeks leaving no sequelae in the majority of cases. No recurrences are described. We report a case of a 42-day old girl admitted at our hospital with Acute Hemorrhagic Edema of Infancy.

    ABSTRACT: Background: Vineyard workers (VW) are exposed to various respiratory allergens. The aims of the study were to determine the prevalence of work related respiratory symptoms (WRS) in Champagne VW in France and to analyze the relationships between symptoms, occupational exposure and sensitization profile. Methods: VW of Reims area were prospectively recruited between 2007 and 2010. Demographic and occupational characteristics were recorded. Respiratory symptoms were scored for each month of the past year. Results of respiratory functional tests and skin prick tests for common respiratory allergens, grape moulds and vine pollen were recorded. Results: 307 subjects were included. The prevalence of WRS was 11%. Compared to subjects with symptoms unrelated to work, subjects with WRS were more frequently sensitized to gramineae (34% vs 18%, p = 0.05), described ocular itching (74% vs 37%, p < 0.001) and seasonal symptoms (88% vs 69%, p = 0.03) mainly during lifting and trellising (57% vs 17%, p < 0.001). Conclusion: WRS are frequent in Champagne WV and are associated with a sensitization to gramineae and with activities performed close to vine in late spring.

    ABSTRACT: Although this highly refined diagnostic approach has been used in several fields of allergy diagnosis, we noticed the scarcity of data on the role of CDR in detecting current sensitization to the allergens of common pets (cat / dog) and, especially, its potential usefulness in predicting the risk of sensitization to other furry animals. Reported data suggest that cross-reacting mechanisms might play an important role in a significant proportion of allergic sensitizations to furry animals (common pets and unusual / exotic mammals) especially in the absence of any possible direct / indirect contact. In this context an evaluation of specific IgE by using the micro-array technique ImmunoCAP ISAC (Thermofisher Scientific - Immuno-Diagnostics, Sweden) for lipocalins (Can f 1, Can f 2, Equ c 1, Fel d 4, Mus m 1) and albumins (Bos d 6, Can f 3, Equ c 3, Fel d 2) might be very useful to evaluate the possibility of cross-reactions between the allergens of different animals. In fact, allergic sensitization without animal exposure is a relevant risk for patients, because they are not aware about the possibility that even severe respiratory symptoms may develop after an occasional animal contact. This aspect should be taken into account by susceptible individuals before acquiring new pets, after removal of common pets or beginning a contact for working / leisure activity with a common as well as uncommon animal.

    ABSTRACT: Background: Even though the Parietaria pollen season may be rather long, many physicians think that Parietaria pollen is a perennial allergen present along the whole year. In fact, many doctors prefer to prescribe allergen immunotherapy (AIT) in Parietaria allergic patients, using continuous courses. On the other hand, physicians usually prescribe pre-co-seasonal AIT course for other pollen allergies. Objective: This study aimed at investigating whether a single pre-co-seasonal AIT course could be effective in Parietaria allergic patients. Methods: Globally, 59 subjects (31 males, mean age 35.9 years) were retrospectively evaluated. All were treated with SLIT as a pre-co-seasonal course: 33 with Parietaria extract and 26 with birch extract. Patients' perception of symptom severity and medication use was assessed by visual analogue scale, comparing the previous pollen season and the present. Results: The Parietaria 2012 pollen season started from the 60(th) day and ended at the 205(th) day of 2012. A single pre-co-seasonal SLIT course was able to significantly (p < 0.0001) reduce symptom severity and medication use. Conclusion: This preliminary study demonstrates that Parietaria pollen season in Genoa lasted about six months and a single pre-co-seasonal SLIT Parietaria course could be sufficient to reduce symptom severity and medication use.

    ABSTRACT: We report the case of a 55-year-old man who went into anaphylactic shock six hours after eating a meal containing meat. He reported having had several tick bites in months before the reaction. The serum specific IgE showed strong positivity to alpha-gal. This is clearly alpha-gal anaphylaxis with delayed onset after meat ingestion caused by tick bite, confirmed by alpha-gal IgE positivity.

    ABSTRACT: On February 4, 2010 the CDC's Advisory Committee on Immunization Practices voted for universal flu vaccination to expand protection against the flu throughout the United States. In addition to this administration expansion, six new influenza vaccines have been introduced into the market possibly introducing new allergenic potentials. We report two cases of delayed anaphylaxis to the flu vaccine.

    ABSTRACT: Eosinophilic esophagitis (EoE) is an inflammatory immune-mediated disease with predominant eosinophilic inflammation characterized by the presence of esophageal dysfunction symptoms. Treatment delay can be associated with disease complications, like esophageal strictures, that can justify the use of invasive procedures which are not deprived of side effects. We present a case report of a 14 year old child with severe esophageal stricture secondary to EoE, that was treated with topical and systemic corticosteroid before any invasive procedure was considered. After 26 weeks of medical treatment, significant improvement of esophageal dysfunction occurred with histological remission and stricture resolution. In patients with severe esophageal strictures secondary to EoE, the need for esophageal dilation procedures should be considered only after anti-inflammatory treatment.

    ABSTRACT: It's well known that iv. immunoglobulins may be useful to overcome habitual abortions, but the mechanisms at the base of a successful outcome and the likelihoods are still unknown. In one hundred and sixty women with habitual abortions and one hundred and sixty healthy mothers, we evaluated blood IgG subclasses; among the patients, sixteen merely showed IgG subclass deficiency, after leaving out any autoimmunity and/or coagulation disorders. All the patients (100%) showed IgG3, twelve (75%) IgG1, eight (50%) IgG4 and six (37,5%) IgG2 deficiency; healthy control people's IgG subclasses fell in normal range in 156 women, but just four women showed IgG2 and IgG4 deficiency with neither immune deficiency's clinical marks nor increased vulnerability to infections. All the patients were treated with whole immunoglobulins iv. infusion (200 mg/kg/monthly) all over the pregnancy. The successful pregnancy rate is very high (> 90%): 100% out of women showing IgG1 (12/12), 87,5% of IgG3 (14/16), 75% of IgG4 (6/8) and 66% of IgG2 deficiency (4/6) had successful pregnancies. The Odd's Ratio between IgG subclass deficiency and recurrent abortions is 4,33 with confidence interval of 95%; chi square value is 7.68 (p < 0.025). Low dose immunoglobulin infusion is the only effective way to reach successful pregnancy, despite previous habitual abortions in patients suffering from IgG subclass deficiency without autoimmunity and/or coagulation disorders, likely restoring idiotype-antiidiotype network; showing evidence of IgG subclasses deficiency (mostly IgG1 and IgG3) may help identify patients who can benefit from iv. immunoglobulin treatment.

    ABSTRACT: Background. Attempts aimed at inducing food tolerance through oral food desensitization (OFD) for the treatment of IgE-mediated food allergies are increasing. In Italy, a number of allergy centres offer this procedure. Objective. To collect information on how these centres are organized, how patients are selected, the methods used to administer OFD and how adverse reactions are managed. Methods. A questionnaire was e-mailed to all the Italian allergy centres offering OFD. Results. The survey shows a high degree of variability between centres. A correct diagnosis of food allergy is crucial for selecting patients for OFD. In the Italian allergy centres, oral food challenges are mostly open label (84%), but in 16% of cases they are single-blind (8%) or double-blind (8%). A high proportion of allergy centres (83%) offer OFD to children presenting forms of anaphylaxis triggered by traces - or very low doses - of food allergen. The majority of allergy centres (76%) enroll patients over 3 years of age, with 44% enrolling patients above the age of 5. Not-controlled asthma, unreliability of parents in the management of OFD and/or risk of adverse events, are the main reasons for exclusion from the procedure. Conclusion. Although OFD may sometimes be successful and may be considered a valid alternative to an elimination diet, further randomized controlled trials are needed, in order to clarify some controversial points, such as the characteristics of the child undergoing OFD, and the methods of food preparation and administration. Moreover, further studies should further investigate OFD safety, efficacy and costs.
