What Proteins Cause Cow ’ s Milk Protein Allergy?
Discussion Cow’s milk protein allergy (CMPA) is one of the most common food allergies. It is estimated to have an incidence of 2-7.5% in infants and a prevalence of 0.5% in breastfeed infants. The prevalence decreases with age at 1% in children> or = 6 years. CMPA does not have a laboratory test and therefore is a clinical diagnosis. It is defined as a “hypersensitivity reaction brought on by specific immunologic mechanisms to cow’s milk.” Generally symptoms present within the first month of life and involve 2 of more systems with 2 or more symptoms. Systems are dermatologic (including atopic dermatitis, urticaria, oral pruritis), respiratory (including asthma, stridor, wheezing, rhinoconjunctivitis) and gastrointestinal (including emesis, diarrhea, constipation, malabsorption, gastroestophageal reflux disease) and other symptoms may include colic, irritability, failure to thrive or food aversion. IgE-mediated CMPA (Type 1 hypersensitivity reaction, ~50% of children) has symptoms that occur within minutes to 2 hours of ingestion of the CMP. Non-IgE mediated CMPA (Type 4 delayed hypersensitivity reaction) has symptoms that occur 4 or more hours (even up to 1 week) after exposure to CMP. Allergic colitis can have blood mixed into stools that are usually non-foul smelling, mucousy or foamy. Blood can be hematochezia or melanotic or insidious. The mechanism for rectal bleeding is felt to be ulceration of thinned mucosa that is stretched over enlarged h...

Atopic dermatitis (AD) is a chronic, pruritic immune-mediated inflammatory dermatosis characterized by a T helper 2 (Th2) immune response phenotype and may be associated with systemic inflammation. Dupilumab is an interleukin 4 (IL-4) receptor α-antagonist that inhibits IL-4 and IL-13 signaling through blockade of the shared IL-4α subunit. Blockade of IL-4/13 is effective in reducing Th2 response. Dupilumab has recently been approved in the United States and Europe for the treatment of adult patients with moderate-to-severe AD.
ConclusionOur data indicate that area of residence has a modifying effect on the relationship between disease severity and HR‐QoL, with a more negative impact on HR‐QoL in metropolitan than in non‐metropolitan areas. This information is important with respect to fully appreciating the burden of occupational hand eczema.

BLACK mould and damp is a common problem during this time of year and respiratory problems, allergies, and asthma can be a result of infestations. Inhaling tiny bits of mould can also cause a condition called aspergillosis. The NHS explains how best to get rid of mould and damp problems.
This study recruited 50 patients with chronic stable asthma and 40 healthy individuals as a control group. Data on age, sex, severity of asthma, PFT and details of drug therapy were obtained from each group. Serum magnesium, potassium, phosphorus, calcium, and sodium levels were also measured. Student ’s t test or Mann Whitney U test for continuous variables, and chi-square test for categorical variables were performed to evaluate differences between groups. Results: In the asthma group, 10% (n = 9) of the patients had hypomagnesemia and 5.5% (n = 5) of the patients had hypophosphatemia. Patie nts with asthma were di...
