RESUMO
BACKGROUND: Some studies have showed that seasonality is an important determinant of vitamin D (vitD) status. OBJECTIVE: We evaluated whether there are differences in individual trends of serum vitD level over one year in asthmatic and rhinitic children. MATERIALS AND METHODS: Ninety-two asthmatic and rhinitic paediatric patients were followed up for one year and their serum vitD level was detected at three-month intervals, once in each season. RESULTS: We observed higher vitD levels at the end of summer and lower at the end of winter. However, the individual seasonal trend was very variable and unpredictable. If it is true that in a given season the majority of patients followed one direction (increase or decrease of serum vitD levels), nevertheless a substantial percentage behaved differently and unpredictably. For example, at the end of spring, 70% of patients showed an increase in serum vitD levels, but 30% showed a decrease. In addition, five individuals had a value ≥50ng/ml in September and showed serum vitD levels ≥30ng/ml throughout the year; 16 patients presented vitD value ≥40ng/ml in September and always had ≥20ng/ml in the other months. CONCLUSIONS: The wide and unpredictable variability of the individual trend of serum vitD levels should be taken into account before deciding whether or not a drug supplementation is appropriate.

Food protein induced enterocolitis syndrome (FPIES) is a food-related gastrointestinal hypersensitivity disorder, probably non-IgE-mediated. Over the years, various diagnostic criteria have been proposed to identify FPIES. In the last few years, there was an increased interest from researchers about FPIES's syndrome, that frequently brought to discover new aspects of this disease. We describe an unusual case of FPIES to egg in a 21-months-old child, because of its clinical characteristics that reflect some aspects of IgE-mediated allergy and other of non IgE-mediated allergy. Although we believe that the most correct diagnosis for our case is FPIES, we think also that this is undoubtedly an atypical form. This is in fact, the first description of a patient who simultaneously has both clinical expressions of IgE-mediated FA that of FPIES. Our case highlights the need to review criteria for FPIES diagnosis.

BACKGROUND: Therapy for moderate to severe acute food protein-induced enterocolitis syndrome (FPIES) typically consists of intravenous fluids and corticosteroids (traditional therapy). Ondansetron has been suggested as an adjunctive treatment. We aimed to evaluate the efficacy of the parenteral (intravenous or intramuscular) ondansetron vs traditional therapy to resolve the symptoms of acute FPIES. METHODS: Cases of FPIES who had a positive oral food challenge (OFC) were retrospectively examined at two major hospitals over a two-year period (Rome, Italy; and Sydney, Australia). The efficacy of therapy, based on the percentage of cases who stopped vomiting, was compared in cases who received parenteral ondansetron and in cases who received traditional therapy or no pharmacological therapy. RESULTS: A total of 66 patients were included: 37 had parenteral ondansetron, 14 were treated with traditional therapy, and 15 did not receive any pharmacological therapy. Nineteen percentage of children treated with ondansetron continued vomiting after the administration of the therapy vs 93% of children who received traditional therapy (P < 0.05, relative risk = 0.2). Children who received ondansetron or no therapy were less likely to require an admission overnight compared with those who received traditional therapy (P < 0.05). CONCLUSIONS: Parenteral ondansetron is significantly more effective than traditional therapy in resolving acute symptoms of FPIES. The relative risk = 0.2 greatly reduces the bias linked to the lack of randomization. These findings suggest an effective treatment for vomiting in positive FPIES OFCs and allow for more confidence in performing OFCs.

Errors involving patients receiving intrathecal chemotherapy are a significant problem in oncology. Despite the improvement in the management of antineoplastic agents, unintentional intrathecal administration of chemotherapic drugs that are indicated only for systemic administration or intrathecal overdose of drugs regularly used for intrathecal chemotherapy, continue to occur. These events can result in severe neurotoxicity, usually fatal in outcome. We review reported cases of medication errors in intrathecal administration of chemotherapy described in the literature. Diverse rescue therapies have been proposed but the most effective means of managing these errors remains prevention.
