Dentists, as well as other dental personnel are constantly exposed to a number of specific occupational hazards. These cause the appearance of various ailments, specific to the profession, which develop and intensify with years. In many cases they result in diseases and disease complexes, some of which are regarded as occupational illnesses. Relying on relevant literature, the present paper dis...

Adverse reactions to local anesthetics are relatively common, but true IgE-mediated hypersensitivity is extremely rare. Fortunately, the vast majority of adverse reactions occur via nonimmunologic means, but considerable confusion still exists among providers. We conducted a review of the literature to determine if earlier estimates of IgE-mediated allergy are consistent with current reports an...

Polymers not only possess repairing functions concerning the concrete structures, but also due to their properties are used in making different types of polymer cements and improving the matrix structure of cement materials, enhancing the viscosity, mechanical, and stability power of concretes. Today, there is limited knowledge on the use of SBR in structural light aggregate concrete. In the pr...

Haemodialysis (HD)-associated anaphylactic and anaphylactoid reactions are found to be a complex problem, and though they have been well-documented in literature, a number of unexplored aspects remain. Anaphylaxis is a severe, life-threatening, generalized or systemic form of hypersensitivity. The clinical diagnosis is based on case history and physical examination, and includes symptoms of air...

Hypersensitivity drug reactions (HDRs) vary over time in frequency, drugs involved, and clinical entities. Specific reactions are mediated by IgE, other antibody isotypes (IgG or IgM), and T cells. Nonspecific HDRs include those caused by nonsteroidal anti-inflammatory drugs (NSAIDs). beta-Lactams--the most important of which are amoxicillin and clavulanic acid--are involved in specific immunol...

Chlorhexidine is widely used as an antiseptic and disinfectant in medical and nonmedical environments. Although the sensitization rate seems to be low, its ubiquitous use raises the possibility of sensitization in many patients and medical care workers. We describe a patient with anaphylaxis during digital rectal examination with chlorhexidine jelly. Urticaria, angioedema, dyspnea, and hypotens...

studies suggest that children who start solid foods early are at risk for developing food allergies. herein, we evaluated the effects of the introduction of peanuts to the diets of children on emerging peanut allergies. children with allergic rhinitis and asthma were enrolled in the present study and evaluated in four stages. in the first stage, a clinical history was completed for all particip...

the present study was conducted to examine the effect of using latex and nitrile examination gloves on hand dexterity.  a  sample  consisting  of  30  university  students  from  urmia  university  of  medical  sciences participated in this study in 2013. the participants conducted purdue pegboard test in three experimental conditions: bare hand (control), with latex gloves and with nitrile glo...

Allrgic reaction to natural rubber latex have increased during past 10 years especially among health worker and patients with high exposure to latex allergen. Latex allergy is associsted with clinical or serological cross reactivity to plant derived food allergcn especially tropical fruit for example avocado bannana chestnut kiwi papaya potato and peaches. In this study on health worker among 5...
