RESUMEN
Summary: Introduction. Acute urticaria (AU) in children is a common clinical manifestation responsible for admission to the emergency department (ED). We aimed to analyze the epidemiological characteristics of AU in children and to identify predictors of both severity and progression. Material and methods. We evaluated 314 children admitted to the ED with a diagnosis of AU. We analyzed information concerning its onset, duration, severity, possible triggering factors, and the persistence of symptoms after 1, 3, and 6 months. Results. The most common etiological factors were infections (43.9%); in up to 32.4% of cases, AU was considered as idiopathic. AU was significantly most common in males and pre-school children. At the 6-month follow-up, 9.5% of children presented a persistence of urticaria, mainly those with contact (44.4%) or idiopathic (30.4%) forms. Conclusions. The AU etiology identified by history in the ED may be a significant predictor of persistence after a first attack of AU.

Summary: The clinical usefulness of two commercial peach extracts for SPT (by Lofarma SpA and ALK-Abellò, respectively) was compared in a multicenter study carried out in Italy. Peach allergic patients were tested with the two extracts in parallel and underwent the detection of IgE specific for all three peach allergens currently available (Pru p1, Pru p3, and Pru p4, respectively). The two extracts were almost identical in terms of sensitivity and specificity, being able to detect virtually all patients sensitized to stable peach allergens (lipid transfer protein (LTP) and, presumably, peamaclein) but scoring negative in patients exclusively sensitive to labile allergens (either PR-10 and/or profilin). Thus, the two extracts represent an excellent tool to carry out a preliminary component-resolved diagnosis of peach allergy at the first patient visit.

Summary: Background and Objective. Sensitization and allergy to shrimp among Italian house dust mite allergic patients are not well defined and were investigated in a large multicenter study. Methods. Shrimp sensitization and allergy were assessed in 526 house dust mite (HDM)-allergic patients submitted to the detection of IgE to Der p 10 and 100 atopic control not sensitized to HDM. Results. Shrimp allergy occurred in 9% of patients (vs 0% of 100 atopic controls not sensitized to HDM; p minor 0.001). Shrimp-allergic patients were less frequently hypersensitive to airborne allergens other than HDM than crustacean-tolerant subjects (35% vs 58.8%; p minor 0.005). Only 51% of tropomyosin-sensitized patients had shrimp allergy, and these showed significantly higher Der p 10 IgE levels than shrimp-tolerant ones (mean 22.2 KU/l vs 6.2 KU/l; p minor 0.05). Altogether 53% of shrimp-allergic patients did not react against tropomyosin. Conclusions. Shrimp allergy seems to occur uniquely in association with hypersensitivity to HDM allergens and tropomyosin is the main shrimp allergen but not a major one, at least in Italy. Along with tropomyosin-specific IgE levels, monosensitization to HDM seems to represent a risk factor for the development of shrimp allergy among HDM allergic patients.

AIM: The aim of this study was to determine the prevalence of OSAS' risk in children of the province of Catanzaro, Italy. MATERIALS AND METHODS: A sample of 2445 scoolchildren aged 6 to 12 years of the province of Catanzaro (Italy) were administered the Pediatric Sleep Questionnaires (PSQs) in its validated Italian version. A total of 1772 questionnaires were collected; however, 130 of them were excluded, and 1642 questionnaires were accepted and scored. RESULTS: According to final scores of questionnaires, 172 children (10.47%) were considered at risk for OSAS. No statistically significant association between sex and risk of OSAS was found (p = 0.189). The risk of OSAS was equally distributed in all ages (p = 0.984). It was found that the most common habits in children with risk of OSAS were: snoring, heavy or noisy breathing, oral breathing, xerostomia, difficulty waking up in the morning, behavioural disturbances during the day and excess weight. CONCLUSION: The study showed a high risk of OSAS, suggesting the importance of first-level screening and the need to pay special attention to the diagnosis of this syndrome.

Allergen extracts for sublingual immunotherapy (SLIT) are currently marketed by several manufacturers, with administration schedules and amount of allergen(s) quite variable in the different products, although almost all are standardized biologically or immunologically. The allergen extracts for SLIT are available in two main pharmaceutical forms: solution to be delivered by drop-counters, pre-dosed actuators (mini-pumps) or disposable single-dose vials; tablets with appropriate composition that allows a slow (1-2 minutes) dissolution in the mouth in contact with saliva. In Europe, SLIT is prescribed in general for one or a few allergens, and mixtures are less used, though there is no immunological contraindication to give multiple allergens. SLIT traditionally involves a build-up phase and a maintenance phase with the top dose. The build-up phase has usually the duration of 4 - 6 weeks. The patient must start with the lowest concentration and gradually increase, using the different dosage preparations, until the maintenance dose is reached. Rush and ultra-rush inductions have been introduced, based on the safety profile of SLIT that is very favorable. For these reasons it has been suggested that an updosing phase maybe even not necessary. The no-updosing approach would result in a treatment that is more patient-friendly and convenient to manage. Indeed, the most recent randomized trials were performed with the no-updosing regimen and their results in term of safety were as favorable as the studies performed with the traditional updosing approach. The currently recommended duration of SLIT is comprised between 3 and 4 years depending on the clinical response in single patients.

This update on treatment of asthma exacerbations in children is the result of an Italian Pediatric Society Task-force, made up of a panel of experts working in 2007-2008. The aim is to give clear indications on the use of the drugs most employed in children, grading the quality of evidence and the strength of recommendations. Suggestions on their limits due to unlicensed and off-label use are reported. The level of evidence and the strength of recommendations for different therapeutic approaches demonstrate that frequently the use of drugs in children is extrapolated from the experience in adults and that more studies are required to endorse the correct use of different drugs in asthmatic children.

Urinary tract infections are often associated with urinary anomalies. An appropriate pharmacologic treatment may prevent, or may at least limit, any kidney damage due to pyelonephritis. The antibiotic prophylaxis plays a role as significant as early surgical therapy, taking into consideration also the present limitative trend for a softer therapeutic regimen. In the past few years a greater bacterial resistance has emerged against some commonly administered antibiotics. Cefixime (3rd generation cephalosporin) has been used on a wide series of patients suffering from urinary infections associated with urinary tract anomalies. A few significative results emerge from the present study. In conclusion, cefixime's effectiveness long-term prophylaxis of urinary infections associated with anomalies.
