BACKGROUND Nickel, cobalt and chromium are some of the most common causes of type IV sensitizations and subsequent allergic contact dermatitis. Accurate diagnosis of contact sensitization to these metal salts is made possible through standardized patch testing; however, patch tests with metal allergens may be influenced by meteorological conditions at the time of testing. We aimed to investigat...

BACKGROUND Burning mouth syndrome (BMS) is a burning or sore mouth in the absence of changes in the oral mucosa. It is often difficult to diagnose and treat. Numerous theories of the etiology have been suggested, including contact allergy. OBJECTIVE To determine the clinical utility of patch testing in patients with BMS. METHODS We retrospectively reviewed the charts of patients diagnosed w...

OBJECTIVES Unnecessary duplicate laboratory testing is common and costly. Systems-based means to avert unnecessary testing should be investigated and employed. METHODS We compared the effectiveness and cost savings associated with two clinical decision support tools to stop duplicate testing. The Hard Stop required telephone contact with the laboratory and justification to have the duplicate ...

BACKGROUND Patch testing has been used as a screening tool to identify those allergens responsible for the development of allergic contact dermatitis. The objectives of this study were to identify the most common allergens found at the Patch Testing Clinic (PTC) of the Department of Dermatology, Medical Sciences Campus (MSC) University of Puerto Rico (UPR), to correlate patch testing results wi...

abstract: in the present paper, we give a necessary and sufficient condition for contact cr-warped product to be contact cr-product in kenmotsu space forms.

The understanding and experimentation of abrasive wear mechanisms at high speeds is still poorly investigated in literature. This mainly due to a lack suitable, well-instrumented test rigs for fundamental, single events. Standard scratch tests, which are often utilized studies abrasion phenomena, operate the low-speed range up some mm/s, while applications suffering from exceeding 1 m/s (e.g., ...

ultrasonic testing (ut), a nondestructive testing (ndt) method, is under development for quality determination of agricultural products, although it has long been used in the food industry. determination and measurement of product quality are important in modern agricultural research. noninvasive/nondestructive quality determination is a novel aspect of the postharvest process in which paramete...

The success of contact tracing in minimizing the risk others being infected during pandemic relies on appropriate sharing information with those individuals who are responsible for identifying and notifying people have come a person has an active COVID-19 case.
