RESUMO
BACKGROUND: Orofacial granulomatosis (OFG) is characterized by granulomatous inflammation of the soft tissues of maxillofacial region. We explored OFG patients from 10 different Italian centers and summarized the most recent literature data. METHODS: A review of patients with OFG was carried out. An extensive online literature search was performed to identify studies reporting diagnosis and management of OFG. RESULTS: Thirty-nine patients were recruited between January 2018 and February 2020. Most of them (97.4%) displayed involvement of the lips, and 28.2% suffered from Melkersson-Rosenthal syndrome. Two patients received diagnosis of CD and one patient of sarcoidosis, suggesting secondary OFG. Oral aphthosis and cervical lymphadenopathy were also described. The mean diagnostic delay was 3.4 years. Histological evaluation was performed in 34/39 patients (87.2%); non-caseating granulomas were found in 73.5% of them. Neurological symptoms (28.2%), gastrointestinal symptoms in absence of overt inflammatory bowel disease (IBD) (20.5%), and atopy (35.9%) were also identified. Therapeutic approaches varied among the centers. Steroids (51.3%) were used with good or partial results. Anti-TNF-α and anti-IgE monoclonal antibodies were used in 6 (15.4%) and 1 (2.6%) patients, respectively, with variable results. Surgery was the choice for 2 patients with good response. CONCLUSIONS: OFG is a rare and neglected disease showing multiple clinical phenotypes. While early diagnosis is crucial, management is difficult and highly dependent on the expertise of clinicians due to the lack of international guidelines. There is a need to establish registry databases and address challenges of long-term management.

BACKGROUND: Egg allergy is one of the most frequent food allergies in childhood while adult onset of egg allergy is a rare condition. CASE PRESENTATION: We report the case of a 30 years old man sent to our center in order to investigate gastrointestinal symptoms occurring since 2 years after egg and derivatives intake. He did not suffer from egg or other food allergies in childhood. He is an active smoker with a contact dermatitis related to nickel and mild allergic rhinoconjunctivitis to grass pollen. Skin prick test and serum specific IgE to egg were performed and revealed sensitization to egg proteins. CONCLUSIONS: Even though IgE-mediated egg allergy affects children, this report witnesses a rare case of adult onset.
RESUMO
BACKGROUND: Ragweed allergy represents a challenge for allergists due to its increase in some geographic areas, mainly northern Italy. OBJECTIVES: To compare two allergy centers in northern Italy by analyzing both the pollen count and the patient characteristics (sensitization and allergy prevalence) over a 10-year period. METHODS: Pollen counts for 10 years (2004-2013) were evaluated and compared in the two centers. Characteristics of patients who were sensitized and allergic to ragweed were analyzed. RESULTS: There was a significantly higher pollen count in Busto Arsizio than in Novi Ligure (p < 0.001). The patients who were seen in the Busto Arsizio center showed more frequent sensitization (p < 0.01) and allergy (p < 0.05) to ragweed than patients who were seen in the Novi Ligure center. The pollen count was significantly (p < 0.01) associated with sensitization and allergy difference. Allergic asthma was more frequent (p < 0.05) in Busto Arsizio. CONCLUSIONS: The pattern of sensitization and allergy prevalence seemed to be associated with ragweed pollen pressure, such as quantity. The knowledge of the pollen count is relevant in clinical practice, mainly for the management of patients with allergy.
