Review Comparative StudyEffectiveness of subcutaneous versus sublingual immunotherapy for the treatment of allergic rhinoconjunctivitis and asthma: a systematic review.
Allergen-specific immunotherapy is widely used in the management of patients with allergic rhinoconjunctivitis and asthma, but the best route of delivery is unclear. ⋯ Our review provides low-grade evidence to support that SCIT is superior to SLIT for reduction in asthma symptoms and moderate-grade evidence for reduction of allergic rhinoconjunctivitis. Additional studies are required to strengthen this evidence base for clinical decision making.

ReviewFood protein-induced enterocolitis syndrome (FPIES): current management strategies and review of the literature.
Food protein-induced enterocolitis syndrome (FPIES) is a non-IgE-mediated gastrointestinal food hypersensitivity that manifests as profuse, repetitive vomiting, often with diarrhea, leading to acute dehydration and lethargy or weight loss and failure to thrive if chronic. FPIES is elicited most commonly by milk and soy proteins; however, rice, oat, and other solid foods may also elicit FPIES. ⋯ The aim of this review is to provide case-driven presentation of the features of FPIES. Although randomized clinical trials on management options are missing, the relevant current literature and authors' experience are reviewed in detail.

Food protein-induced enterocolitis syndrome: insights from review of a large referral population.
Food protein-induced enterocolitis (FPIES) is a rare non-IgE mediated disease. Most studies have been limited in nature, with the largest cohort being 66 patients. The most common foods that have been reported are milk and soy. ⋯ FPIES reactions were seen more frequently than previously described. However, the presentation and clinical features were similar to previous reports. Milk- and soy-triggered FPIES were common, and 43.5% of patients who had a milk trigger reacted to soy. There is no laboratory test to identify foods that cause FPIES, and clinician-supervised oral food challenge is the only definitive test available.

A 50-year-old woman with nonallergic rhinitis, asthma, and aspirin intolerance presented with worsening symptoms of nasal congestion, purulent drainage, and anosmia. Nasal polyps were visualized on anterior rhinoscopy, and there was evidence of chronic rhinosinusitis (CRS) on imaging studies during work-up for another medical condition. Over a 2-year period she had numerous bouts of acute exacerbations of CRS which required multiple courses of antibiotics; however, she was unwilling to undergo surgery to reduce polyp burden. ⋯ Nasal obstruction is a common symptom that can result from multiple causes, including mucosal disorders (eg, allergic and nonallergic rhinitis, rhinosinusitis, sarcoid) and structural disorders (eg, nasal septal deviation, tumors, mucoceles). The various causes and work-up for nasal obstruction are discussed with emphasis placed on CRS, which is a prevalent disease characterized by inflammation of the nose and paranasal sinuses for a duration of >12 weeks. The different subtypes of CRS, including CRS with and without nasal polyps, allergic fungal rhinosinusitis, and aspirin-exacerbated respiratory disease, are discussed along with pathogenesis, diagnosis, and treatment options.

Case ReportsImmediate allergic hypersensitivity to quinolones associates with neuromuscular blocking agent sensitization.
We identified a case of quinolone allergic hypersensitivity associated with quaternary ammonium (QA) sensitization, the allergic determinant of neuromuscular blocking agents (NMBAs). Concomitant sensitization to several chemically different drugs is rarely reported and raises the question of a nonfortuitous association. ⋯ We report here the first documentation of a high prevalence of QA sensitization in patients with quinolone allergic hypersensitivity. These results suggest a new way for NMBA sensitization. It thus seems appropriate to investigate NMBA sensitization when quinolone allergic hypersensitivity is diagnosed.
