BACKGROUND: The study objective was to compare age-related differences in the cause and clinical presentation of anaphylaxis. METHODS: We conducted a prospective study of patients visiting the emergency department for anaphylaxis. Data were collected from 3 emergency departments from 1 April 2014 to 31 December 2015. Patient electronic records with the diagnoses of allergy, angioedema, urticaria, and anaphylaxis (ICD-9 codes 9953, 9951, 7080, 9950, 7089) were screened and cases fulfilling World Allergy Organisation criteria for anaphylaxis were included...

The aim of our study is to explore the features of clinical manifestations and genetic mutations in Chinese CAPS patients. Fifteen confirmed patients with CAPS were enrolled. The onset time ranges from 2 days after birth to 6 years and 1 month. Recurrent urticaria rash (93.3%) with fever (100%) were two dominant characteristics of these patients that were presented as either acute or chronic process. Systemic involvements were found in all patients except for one with only rash and fever. The top three symptoms were fever (100%), rash (93...

The efficacy of oral acitretin in the systemic treatment of severe and recalcitrant dermatoses has been established in a large number of clinical trials. Its mucocutaneous and ocular adverse reactions are common or relatively common, whereas systemic side effects are either uncommon or rare and include teratogenesis, hyperlipidemia, hepatotoxicity, intracranial hypertension, myopathy, and peripheral neuropathy. Angioedema is a term used to describe an acute, solitary or multiple, circumscribed, and non-pitting mucocutaneous swelling that affects the dermis and the subcutaneous tissue, lasts 24 to 72 hours, and may become potentially life-threatening when the pharynx and/or the larynx are involved...

BACKGROUND: Skin infections account for 40% of emergency visits in pediatric dermatology. It is important to promptly recognize skin infections with potential complications and initiate treatment. However some characteristic skin findings may imitate skin infections and are often misdiagnosed. OBJECTIVES: To illustrate frequent pediatric skin infections and pitfalls in view of imitators and differential diagnoses. MATERIALS AND METHODS: A photo quiz is presented with the discussion of a selection of acute pediatric skin infections in comparison to their infectious or noninfectious differential diagnoses...

BACKGROUND: The classic histopathological findings of urticaria include dermal edema and a sparse perivascular infiltrate of neutrophils, eosinophils, macrophages, and lymphocytes. However, this pattern is inconsistently described. OBJECTIVE: To describe the histological and immunofluorescence characteristics of urticaria and to identify distinctive patterns. METHODS: A retrospective study was performed in which the medical files and biopsy specimens of 58 patients with acute and chronic classical urticaria were reviewed...

Ilex cornuta, commonly known as Chinese holly, is an evergreen shrub from the family Aquifoliaceae, and it is widely distributed in Korea and China. In folk medicine, the leaves of I. cornuta are used for treatment of several disorders, including weakness of the waist and knees, arthrodynia, headache, acute conjunctivitis, toothache, urticaria, rheumatic arthralgia, and cardiovascular diseases. In this study, we investigated the anti-inflammatory effects of an I. cornuta leaf ethanol extract (ILE) and its underlying mechanisms of action...

BACKGROUND: Clinical features and basophil activation levels correlate with serum autoreactivity and allergen sensitivity in patients with chronic spontaneous urticaria (CSU). OBJECTIVES: To explore the relationship of the expression patterns of plasma T-helper cell (Th) 1-, Th2-, Th17- and Th22-related cytokines with the serum autoreactivity and the allergen sensitivity in CSU. METHOD: Twenty related cytokines were measured and analysed in 60 patients with CSU, 15 patients with acute urticaria, 10 patients with atopic dermatitis (AD) and 15 healthy persons, respectively...

BACKGROUND: The use of herbal medicines in children and the general population is continually on the rise with an overall herbal lifetime and current use ranging between 0.8%-85.5% and 2.2%-8.9%, respectively. Although acute hypersensitivity reactions are generally considered to be rare, little knowledge exists on the frequency and type of these reactions especially in specific populations like children. OBJECTIVES: To assess the patterns of acute hypersensitivity reactions to herbal medicines reported to the WHO global individual case safety report (ICSR) database VigiBase(®) in children...

BACKGROUND: Acute angioedema of the upper airways can be life-threatening. An important distinction is drawn between mast-cell-mediated angioedema and bradykinin-mediated angioedema; the treatment of these two entities is fundamentally different. METHODS: This review is based on pertinent articles retrieved by a selective search in PubMed and on guidelines concerning the treatment of angioedema. The authors draw on their own clinical experience in their assessment of the literature...

Urticaria is a common, mast cell-driven disease presenting with wheals or angioedema or both. In the last years, urticaria has increasingly attracted notice to clinicians and researchers, last but not least inspired by the approval of omalizumab, an anti-IgE antibody, for urticaria treatment. There is wide consensus on the clinical classification based on duration and elicitation. However, the pathogenesis is incompletely understood. This review summarizes current guidelines for the management and novel insights in the pathogenesis of urticaria with special focus on their impact on clinical praxis...

REVIEW
Paula J Busse, Tukisa Smith
Angioedema is frequently categorized into histamine- or bradykinin-mediated disease. It is critical to determine the underlying mediator of symptoms as it directs treatment. Histaminergic angioedema is the most frequent cause of angioedema. It is classified as either acute (lasting <6 weeks) or chronic (symptoms >6 weeks). It is further classified into angioedema presenting with or without urticaria. Some patients with acute angioedema may have disease that becomes chronic. Mast cells and basophils are central to the underlying pathophysiology of histamine-mediated angioedema...

Little is known about the role of the kallikrein-kinin system in chronic spontaneous urticaria (CSU). Kallikrein 5 (KLK5), a trypsin-like enzyme, is the most abundant in the skin and plays a role in itching and inflammatory reaction. In this study, we determined plasma KLK5 concentration, and its associations with acute phase response in CSU patients. Concentrations of KLK5 in plasma and CRP in serum were measured in patients with CSU of varying severity and in the healthy subjects. Plasma KLK5 concentrations were significantly lower in CSU (all) and moderate-severe CSU patients, as compared with the controls...

Paul Schaefer
Urticaria commonly presents with intensely pruritic wheals, sometimes with edema of the subcutaneous or interstitial tissue. It has a lifetime prevalence of about 20%. Although often self-limited and benign, it can cause significant discomfort, continue for months to years, and uncommonly represent a serious systemic disease or life-threatening allergic reaction. Urticaria is caused by immunoglobulin E- and non-immunoglobulin E-mediated release of histamine and other inflammatory mediators from mast cells and basophils...

BACKGROUND: In Colombia, there have been studies on the prevalence of allergic diseases such as asthma, allergic rhinitis and atopic dermatitis. Prevalence studies of urticaria in Colombia are scarce. OBJECTIVE: Our objective objective of this study was to estimate the prevalence of urticaria in Cartagena (Colombia) in order to contribute to national epidemiological estimates of disease. METHODS: A multicenter cross-sectional study in the city of Cartagena was conducted and 547 patients aged 1-58 years treated at the Allergy specialist consultation in care centers selected for this study between April and July 2015 were included, through non-probabilistic sampling...
