BACKGROUND In the first 6 months of this previously published, randomized trial, the combined intervention of occupant education, insecticide bait application, and professional cleaning significantly reduced cockroach numbers and Bla g 1 allergen levels in inner-city homes. OBJECTIVE This continuation study investigated whether the cockroach allergen reductions achieved by month 6 could be ma...
Background: The German cockroach (Blatella germanica) is one of the most important vectors of public health interest due to its involvement in the transmission of infectious diseases. Different insecticides are used to control cockroaches; however, resistance developed against most of insecticides has made them ineffective. Attempts should always be made to find proper alternat...
BACKGROUND Cockroach allergy is a key contributor to asthma morbidity in children living in urban environments. OBJECTIVE We sought to document immune responses to cockroach allergen and provide direction for the development of immunotherapy for cockroach allergy. METHODS Four pilot studies were conducted: (1) an open-label study to assess the safety of cockroach sublingual immunotherapy (S...
BACKGROUND The relationships between cockroach and mouse allergen exposure, anti-cockroach and anti-mouse IgE, and wheeze, rhinitis, and atopic dermatitis in children as young as age 3 years are of public health importance but have not been thoroughly evaluated. OBJECTIVE We hypothesized that inner-city children might have anti-cockroach and anti-mouse IgE by age 3 years, and their presence w...
background : cockroaches are of vital importance medically and hygienically. they are able to contaminate foods and act as vectors of pathogenic agents such as bacteria, protozoa, and parasites to human environment either mechanically or through their digestive system. cockroaches belong to the phylum arthropoda, class insecta, and order blattodea or blattaria. to date, over 4,500 cockroach spe...
background: asthma is the most common chronic disease of childhood. exposure to allergens plays an important role in asthma. recently, cockroach has attracted attentions as an important allergen. objective: to evaluate cockroach allergy in iranian children with asthma. methods: 100 children with asthma were studied. after determination of asthma severity, serum total ige and blood eosinophi...
background: the german cockroach, blattella germanica l. (dictyoptera: blattellidae), has become resistant to many insecticides due to control failures in hospital and student dormitory settings of southern iran. objective: this study was thus designed to detect and monitor carbamate resistance in two strains of german cockroach using lethal dose bioassay methods. methods: wild dormitory (d) an...
BACKGROUND Studies have demonstrated that IgE-binding cross-reactive epitopes between shrimp, cockroach, and house dust mite tropomyosins can account for the presence of detectable IgE to shrimp in patients with cockroach and dust mite allergies. OBJECTIVE We investigated the correlation between IgE-mediated sensitization to shrimp, cockroach, and dust mite in relation to allergen exposure in...
BACKGROUND Asthma guidelines recommend environmental control practices (ECPs) to improve asthma health. In the inner city, where asthma morbidity is high, it is not known whether children's health status affects the use of ECPs. OBJECTIVE To investigate health status determinants of ECPs in the homes of children with asthma. METHODS Caregivers of children aged 2 to 6 years with (n = 150) an...
