Local reaction to allergen-specific immunotherapy (SIT) usually appears within 30 minutes, but cases with exercise-induced urticaria at the SIT site 2-3 weeks after the last allergen injection have been reported. A 28-year-old man was treated with house dust mite-SIT for 5 years, due to asthma when he was an 11-year-old boy. On a treadmill exercise test for 50 minutes, erythema, swelling, and pruritus occurred at the SIT site, which lasted for one hour. There was no evidence of complement activation, and the skin biopsy specimens showed no apparent difference between the lesion and normal sites in the distribution of inflammatory cells and in mast cell degranulation. However, the morphine, but not the histamine, skin test responses were increased after the exercise. There must be a remaining long-term sequela of the SIT, including an increased releasability of mast cells, even after more than 10 years.

Heat contact urticaria is very rare and it is characterized by the development of wheal limited to the areas of heat contact. We report a case of heat contact urticaria in a 65-year-old women. The wheal was induced by hot bathing, washing in hot water or leaning on hot radiators. Symptoms started within 5 minutes of exposure and lasted 30 to 60 minutes. She had no systemic symptoms. The clinical diagnosis of localized heat urticaria was confirmed by experimental induction of localized wheals. Our investigation showed that the threshold temperature needed for induction of the heat urticaria was 39 degrees C. We tried to investigate the plasma levels of prostaglandin D2 and blood histamine before and after heat challenge. The patient showed marked improvement after a combination treatment of desensitizing by repeated exposure to heat and indomethacine.

OBJECTIVETo study the clinical characteristics of urticaria in children versus adults, and to provide reference for the etiological analysis, disease evaluation, and treatment of urticaria in children.
METHODSThe clinical data of 2 411 patients with urticaria who visited the Department of Dermatology at Xiangya Hospital of Central South University from January 2013 to May 2017 were collected to study their socio-demographic characteristics. The clinical characteristics of urticaria were compared between the 68 children and 672 adults of the 740 patients with complete follow-up data.
RESULTSAmong the 411 pediatric patients, 314 (76.4%) had acute urticaria; among the 2 000 adult patients, 896 (44.8%) had chronic spontaneous urticaria. The causes of acute urticaria in children included infection (41%, 16/39). The accompanying symptoms of acute urticaria in children mainly included abdominal pain and diarrhea (44%, 17/39), while those in adults mainly included chest distress and shortness of breath (32%, 11/34). Compared with the adult patients, the pediatric patients had significantly lower chronic urticaria activity scores before and after treatment (P<0.05), a significantly higher rate of response to second-generation antihistamines (82.1% vs 62.2%; P<0.05), and a significantly higher proportion of individuals with a personal and family history of urticaria (P<0.05).
CONCLUSIONSAcute urticaria is more commonly seen than chronic urticaria in children with urticaria, and the main accompanying symptoms are abdominal pain and diarrhea, which are different from adults with urticaria. Chronic urticaria has a better treatment outcome in children than in adults. The most frequently seen cause of acute urticaria is infection in children. Atopic children may be susceptible to urticaria.

4.Report of a child with neonatal-onset multisystem inflammatory disease and review of the literature.
Chinese Journal of Pediatrics 2014;52(12):932-936
OBJECTIVENeonatal-onset multisystem inflammatory disease (NOMID) is not widely recognized in China. This study aimed to investigate the diagnosis and treatment of NOMID.
METHODTo analyze the clinical characteristics and laboratory results including skin biopsy, gene analysis and serum interleukin 1β of a boy admitted to Peking University First Hospital in November of 2013. Reports on NOMID were searched and the clinical and laboratory characteristics of reported cases were summarized.
RESULTThe patient was a 1-year-old boy. He had urticaria since 2 days after birth, and presented with episodes of fever, aseptic meningitis, symptoms of joints, short statue, hearing loss, abnormal fundus findings, and leucocytosis, high level of c-reactive protein (CRP) and abnormal findings of head MRI including ventriculomegaly and white matter dysplasia. Urticaria was confirmed by skin biopsy. Gene analysis showed T1702T/A in exon 4 of NLRP3 gene, which causes Phe568lle. Serum interleukin 1β increased dramatically. The boy was diagnosed as NOMID. He did not respond to antibiotic therapy and anti-allergy therapy. Corticosteroid therapy induced normalization of body temperature, and alleviation of rash, but not improvement in cerebrospinal fluid cell numbers. After searching reports of NOMID at PubMed, and Chinese literature published before November 2013, we summarized cases from 8 reports and reviewed 148 cases. The results showed that fever, urticaria, meningitis and arthropathy are the most common manifestations of NOMID, only 57% (69/122) of patients had mutation of NLRP3.
CONCLUSIONThis is a rare report of NOMID in children in China. Fever, urticaria, aseptic meningitis and persistently high level of CRP are characteristics of NOMID. Gene analysis and serum interleukin-1β detection can aid in diagnosis.

INTRODUCTIONFood-dependent exercise-induced anaphylaxis (FDEIA) is an uncommon and under-recognised syndrome that clinicians may not consider in a patient presenting with anaphylaxis.
CLINICAL PICTUREWe describe here 5 patients aged 9 to 20 years old who presented at a local tertiary hospital over a 2-year period from August 2006 to July 2008. All presented with urticaria, 4 were hypotensive, 2 had angioedema and another 2 had dyspnoea. The symptoms occurred between 15 and 150 minutes (mean, 81) after exercising and consuming various food. All had consumed shellfish. All patients were admitted with the diagnosis of anaphylaxis of undefined aetiology. Diagnosis of FDEIA was only reached upon referral to an allergist.
TREATMENT AND OUTCOMEPatients were treated with standard medicines for anaphylaxis including adrenaline, antihistamines, steroids and fluid flushes. Symptoms resolved in 2 to 3 days with no further episodes. At discharge, patients were prescribed epinephrine auto-injectors and given written anaphylaxis management plans.
CONCLUSIONSMore public awareness and strategies to ensure accurate diagnosis and management of this condition are necessary.

: Anaphylaxis is a predominantly childhood disease. Most of the literature on anaphylaxis has emerged from Western countries. This study aimed to describe the incidence, triggers and clinical presentation of anaphylaxis among children in Singapore, look for predictors for anaphylaxis with severe outcomes, and study the incidence of biphasic reactions.: We retrospectively reviewed records of children presenting with anaphylaxis to our paediatric emergency department from 1 January 2007 to 31 December 2014.: We identified 485 cases of anaphylaxis in 445 patients. Cutaneous symptoms (urticarial/angio-oedema) were the most common across all age groups (481 cases, 99%), followed by respiratory (412, 85%), gastrointestinal (118, 24%) and cardiovascular (35, 7.2%) symptoms. Central nervous system symptoms (drowsiness/ irritability) were rare across all age groups (11, 2.2%). Food was identified as the most common trigger across all age groups (45% to 63%). Seafood was the most common food trigger (57, 25%). A total of 420 (86.6%) children were treated with adrenaline, 451 (93%) received steroids and 411 (85%) received antihistamines. Sixty-three (13%) children fulfilled the criteria of severe anaphylaxis. There was no statistically significant association between severe anaphylaxis and the type of trigger (= 0.851), nor an overall past history of atopy (= 0.428). The only independent predictor for severe anaphylaxis was a previous drug allergy (= 0.016). A very low prevalence of biphasic reactions (0.6% of study population) was noted in our study.: We described the presentation and management of anaphylaxis in the Singapore population. A history of drug allergy is associated with severe presentation. Biphasic reactions are rare in our population.
