Although the prognosis of maculopapular cutaneous mastocytosis (MPCM), also referred to as urticaria pigmentosa, is often benign, clinicians lack evidence to reliably predict those at risk of associated systemic manifestations. We sought to elucidate clinical markers of disease severity to provide better treatment and prognostic information for individuals with MPCM. A retrospective chart review querying characteristics of children diagnosed with MPCM in the Emory Dermatology Clinic was performed. Follow-up was obtained through a clinical encounter or telephone interview. Linear regression was used to determine predictors of the number of MPCM-related systemic symptoms. Of 67 subjects, 57% were male, and the mean age of onset was 4.5 months. The maximum number of MPCM lesions was 1 to 10 in 16%, 11 to 30 in 33%, 31 to 50 in 25%, 51 to 100 in 6%, and more than 100 in 20% of subjects. For their MPCM lesions, 46% of subjects reported itching, 34% flushing, and 25% blistering. Reported systemic symptoms included diarrhea (22%), abdominal pain (15%), wheezing or dyspnea (13%), vomiting (10%), bone pain (10%), headaches (8%), cough (10%), rhinorrhea (8%), irritability (6%), and anaphylaxis (1.5%). In a multivariate linear regression analysis, the maximum number of MPCM lesions (p = 0.02) and the number of skin symptoms (p < 0.01) were statistically significant predictors of the number of systemic symptoms, controlling for age of onset, body sites involved, and sex. The correlation between cutaneous findings and symptomatology could aid clinicians in identifying individuals with MPCM who might warrant systemic evaluation and therapy.

This article focuses on hypersensitivity reactions after inhalation of food particles as primary cause for food allergy. This is an increasingly recognized problem in children. Reactions are commonly diagnosed in children who develop symptoms when the food is ingested. Some children tolerate the food when it is eaten but they experience reactions to airborne food particles such as peanut, cow's milk, and fish. The exposure can be trivial, as in mere smelling or being in the vicinity of the food. Usually, respiratory manifestations include rhinoconjunctivitis, coughing, wheezing, and asthma, but in some cases even anaphylaxis has been observed. Practical approaches concerning diagnosing clinical reactivity including skin tests, serum IgE antibodies, specific provocation tests, and management have been identified. Studies are warranted to establish the accuracy of diagnostic tests as well as incidence, prevalence, and natural history of food allergy through inhalation route.

In this rostrum we aim to increase awareness of anaphylaxis in infancy in order to improve clinical diagnosis, management, and prevention of recurrences. Anaphylaxis is increasingly reported in this age group. Foods are the most common triggers. Presentation typically involves the skin (generalized urticaria), the respiratory tract (cough, wheeze, stridor, and dyspnea), and/or the gastrointestinal tract (persistent vomiting). Tryptase levels are seldom increased because of infant anaphylaxis, although baseline tryptase levels can be increased in the first few months of life, reflecting mast cell burden in the developing immune system. The differential diagnosis of infant anaphylaxis includes consideration of age-unique entities, such as food protein-induced enterocolitis syndrome with acute presentation. Epinephrine (adrenaline) treatment is underused in health care and community settings. No epinephrine autoinjectors contain an optimal dose for infants weighing 10 kg or less. After treatment of an anaphylactic episode, follow-up with a physician, preferably an allergy/immunology specialist, is important for confirmation of anaphylaxis triggers and prevention of recurrences through avoidance of confirmed specific triggers. Natural desensitization to milk and egg can occur. Future research should include validation of the clinical criteria for anaphylaxis diagnosis in infants, prospective longitudinal monitoring of baseline serum tryptase levels in healthy and atopic infants during the first year of life, studies of infant comorbidities and cofactors that increase the risk of severe anaphylaxis, development of autoinjectors containing a 0.1-mg epinephrine dose suitable for infants, and inclusion of infants in prospective studies of immune modulation to prevent anaphylaxis recurrences.

Tipepidine hibenzate, a central antitussive drug, is widely used in the management of cough and is generally safe and well tolerated. We present here a case of anaphylaxis caused by this drug. When the patient had caught a cold over the previous 10 years, she had received medications, including tipepidine hibenzate, from her family doctor. However, this time, she developed dyspnea, skin eruption, and anaphylactic shock after taking a Chinese herbal medicine and this drug. After her conditions improved due to adequate treatment, she was referred to our hospital to confirm the causative drug. Double-blind placebo-controlled oral challenge tests were performed after obtaining informed consent. Oral challenge with one-third tablet dose of tipepidine hibenzate caused a positive reaction. Urinary leukotriene E4 rose during the challenge with tipepidine hibenzate, but not with control. Clinicians should keep in mind that common antitussive drug use can cause anaphylactic reactions in very rare cases and can be harmful.

One third of all preschool children will have an episode of wheeze and many of these present to primary care. Most will fall within a spectrum of diagnosis ranging from episodic viral wheeze to multiple trigger wheeze or early onset asthma. A small proportion will have other rare, but important, diagnoses such as foreign body aspiration, anaphylaxis, gastro-oesophageal reflux, congenital anatomical abnormalities or other chronic lung diseases. Clinical assessment should try to classify children into either episodic viral wheeze or multiple trigger wheeze phenotypes. In clinical practice children rarely fit neatly into either category and the phenotype may change overtime. Clinical examination may well be normal in a child presenting with chronic symptoms. Urgent outpatient review should be considered for symptoms present from early infancy, chronic wet cough, failure to thrive or systemic involvement. The child should be referred to hospital immediately if you suspect an inhaled foreign body or anaphylaxis (after administering IM adrenaline). NICE recommends immediate referral for children with wheeze and high-risk features and also those with intermediate-risk features failing to respond to bronchodilator therapy. Children with high-risk features on assessment should be treated immediately with inhaled bronchodilator therapy. Those with intermediate risk should be treated immediately with bronchodilator therapy and reassessed 15-30 minutes later. Intermediate-risk children who respond and low-risk children can be managed at home with bronchodilator therapy via a spacer device.

Hydatidosis is caused by Echinococcus granulosus. Humans may be infected incidentally as intermediate host by the accidental consumption of soil, water, or food contaminated by fecal matter of an infected animal. Hydatidosis is one of the most symptomatic parasitic infections in various livestock - raising countries. Lung is the second most commonly affected organ following the liver. The symptoms depend on the size and site of the lesion. It can present as an asymptomatic pulmonary lesion to hemoptysis, chest pain, coughing anaphylaxis, and shock. There are very few reported cases of isolated lung hydatidosis without exposure to animals or nonvegetarian diet. For hydatidosis, serology and imaging are diagnostic tools. Surgical removal and/or chemotherapy are the main-stay of treatment. Here, we discuss a case of persistent left lower lobe cystic lesion in young female with a history of operated left breast carcinoma which was thought to be of metastatic lesion but ultimately confirmed as pulmonary hydatid cyst after unintended aspiration of cystic fluid to rule out malignancy. Pulmonary hydatidosis should always be considered as a differential diagnosis when dealing with a cystic lesion on radiology.

Levodropropizine is commonly used as an antitussive drug for acute and chronic cough. It is a non-opioid agent with peripheral antitussive action via the modulation of sensory neuropeptide levels in the airways. Thus, levodropropizine has a more tolerable profile than opioid antitussives. However, we experienced 3 cases of levodropropizine-induced anaphylaxis. Three patients commonly presented with generalized urticaria, dyspnea, and collapse after taking cold medication including levodropropizine. To find out the culprit drug, we performed skin tests, oral provocation tests (OPTs), and basophil activation tests (BATs). Two patients were confirmed as having levodropropizine-induced anaphylaxis by OPTs, and one of them showed positive to skin prick tests (SPTs). The other patient was confirmed by skin tests and BATs. When we analyzed pharmacovigilance data related to levodropropizine collected for 5 years, most cases (78.9%) had allergic reactions, such as rash, urticaria, angioedema, and anaphylaxis. Therefore, physicians should consider that levodropropizine can be a culprit drug, when anaphylaxis occurs after taking anti-cough or common cold medication.

Vocal cord dysfunction, also known as paradoxical vocal fold motion (PVFM), is a disorder characterized by abnormal vocal cord adduction during inspiration. PVFM is commonly misdiagnosed as asthma because of the similarity of symptoms: cough, wheezing, chest pain, and dyspnea. We present the clinical vignette of a 36-year-old woman with juvenile rheumatoid arthritis and multiple adverse drug reactions who presented with recurrent episodes of unrecognized PVFM during skin testing for drug allergy, omalizumab treatment, and tocilizumab desensitization. Before the diagnosis of PVFM, these episodes were treated as anaphylaxis, including the administration of epinephrine. Once diagnosed and treated for PVFM, the patient did not present any further events and continued treatment for drug allergy. PVFM may be underreported in hypersensitivity reactions because of the similarity to Type 1-mediated respiratory symptoms and comorbid asthma.

Pectin is used in several foods as an additive and a thickner. But some cases of anaphylaxis have been reported. Most of these are induced by occasional exposures; however, no cases of anaphylaxis after eating a Citrus unshiu, the albedo of which is rich in pectin, have been reported.A 7-year-old girl developed barking cough and pruritus approximately two hours after eating a frozen Citrus unshiu. She had a history of anaphylaxis induced by consuming cashew nuts. Skin testing and basophil activation tests were performed using a commercially available pectin product. Both tests were positive. In an oral food challenge test, she felt abdominal pain and nausea only after eating fruit, along with the albedo, of Citrus unshiu. We concluded that this case was induced by pectin present in the albedo of Citrus unshiu, but not by the fruit itself. We should consider that patients with cashew nut allergies have a possibility of pectin allergies as well, and that pectin in the albedo of Citrus unshiu may induce anaphylaxis.

Oral mite anaphylaxis (OMA) caused by mite-containing food that was initially reported in 1993 has become commonly known after accumulating the case reports. Although it has been pointed out as being related to aspirin intolerance overseas, there are only a few cases reported in Japan so far, particularly no case for children. We report a child case which is seemingly related to OMA and aspirin intolerance. The case is for a boy at the age of 10. After eating Takoyaki with the ingredient of mite-containing flour, he was diagnosed as OMA due to the occurrence of anaphylaxis with respiratory discomfort, abdominal pain, and vomiting. One month later, he was suspected of aspirin intolerance, since he presented with symptoms such as swelling of the eyelid and coughing after taking loxoprofen which he never have taken, and intradermal test with loxoprofen was negative. Because the mechanism with a connection between mite allergy and aspirin intolerance still remains unknown, it would be necessary to accumulate more cases and clarify the pathology in future.
