A patient with seropositive, nodular rheumatoid arthritis (RA) developed contact allergy to gold jewellery following a severe skin rash which occurred after 13 weeks of treatment with sodium aurothiomalate. Patch testing confirmed that the contact allergy was due to gold. This is the first proved case of contact allergy to gold or any other compound initiated by systemic administration of the a...

contact lens wearers are at great risk of developing microbial keratitis because of incorrect usages and unhygienic maintenance of contact lenses. therefore, the present study was planned to provide data that will be helpful in selecting the anti-microbial to cure microbial keratitis. one hundred bacterial isolates from conjunctiva of contact lenses wearer were isolated, identified and subjecte...

The purpose of this study was to determine if a horizontal cleavage lesion (HCL) of the posterior horn of the medial meniscus would result in changes to tibiofemoral contact mechanics, as measured by peak contact pressure and contact area, which can lead to cartilage degeneration. To study this, 10 cadaveric knees were tested in a rig where forces were applied (500 N Compression, 100 N shear, 2...

Background. Increasing use of cosmetics has contributed to a rise in the incidence of allergic contact dermatitis (ACD) to cosmetics. It is estimated that 1-5.4% of the population is sensitized to a cosmetic ingredient. Patch testing helps to confirm the presence of an allergy and to identify the actual allergens which are chemical mixtures of various ingredients. Objectives. The aims of this s...

The concept of Design for Assembly (DFA) assure cost effective assembly process by minimizing the assembly efforts. Part count reduction is one of the primary objective of DFA, which reduces the number of assembly levels and assembly tooling. However reducing part count with modified part geometries do not allow to follow the same assembly sequence that of used earlier. In this contest a framew...

IMPORTANCE Contact allergy to methylisothiazolinone (MI) or to the combined formulation of methylchloroisothiazolinone and MI (MCI-MI) has increased significantly, with a frequency of as much as 11.1% in patients with dermatitis; however, few cohort studies in the US population have been reported. OBJECTIVE To investigate the prevalence of contact allergies to MI and MCI-MI and the outcomes o...

Patch testing is essential for identification of culprit allergens responsible for allergic contact dermatitis. This manuscript reviews how to perform patch testing and how to read and interpret the results.
