Non-destructive methods for testing material properties allow for multiple tests to be performed on the same sample, which will speed up the design and testing process for hydrogel contact lenses. The mechanical properties of contact lenses were investigated by microindentation testing. Indenter force responses were recorded for two modes of testing: constant velocity and relaxation indentation...

Online privacy management research related to e-commerce mainly focuses on whether or not to disclose information. Online social networking (OSN) on the other hand, offers a broader set of privacy management strategies. However, how individuals use these OSN strategies has not yet been studied. We survey college students about a popular OSN website and four privacy management strategies: privac...

sera from 495 pregnant women were examined for toxoplasma antibodies by indirect fluorescent antibody testing (ifat). antibodies were positive in 32.7%. seropositivity was not increased significantly with age but showed a statistically significant rise in accordance with frequency of parity, abortion and contact with cats. the high rate of seronegativity (67.3%) observed in pregnant women repre...

Tuberculosis contact investigations are a top priority in TB infection control. The aim is to prevent the spread of infectious disease, identify potential TB sources, and treat individuals who are infected or actively ill. The contact investigation process is quite simple: identify close contacts; examine their symptoms and determine their clinical status; perform a chest X-ray; administer a tu...

The aim of the present study was to evaluate yield and effectiveness of a large-scale contact investigation around a supermarket employee with infectious tuberculosis. Supermarket customers were screened by tuberculin skin test (TST) and/or radiography, depending on individual characteristics. The number of recent infections was estimated based on historical reference data after correction for ...

Background.  In May 2013, a wild poliovirus type 1 (WPV1) outbreak reported in Somalia provided an opportunity to examine the contribution of testing contacts to WPV detection. Methods.  We reviewed acute flaccid paralysis (AFP) case-patients and linked contacts reported in the Somalia Surveillance Database from May 9 to December 31, 2013. We restricted our analysis to AFP case-patients that ha...

Lymphomatoid contact dermatitis is a pseudolymphoma with clinical and histological features of allergic contact dermatitis and cutaneous T cell lymphoma. Incorrect diagnosis may lead to unnecessary testing, unnecessary treatment, or patient harm. The objective of this study is to present a case to demonstrate the diagnostic challenge and overlap between allergic contact dermatitis and cutaneous...

Contact (allergic) dermatitis is a skin disorder related to natural exposure to various allergens. Systemic contact dermatitis (SCD) describes a cutaneous eruption in response to systemic exposure to an allergen. The exact pathologic mechanism remains uncertain. Herein we describe a 36-year-old woman with symmetric systemic allergic contact dermatitis, unresponsive to conventional treatment, as...
