We introduce an automated parametric CAD system for the design of pierced medieval jewellery, where the design of a piece of jewellery is expressed by a collection of parameters and constraints and the user’s participation in the design process is through the definition of parameter values. We present an approach to designing traditional pierced jewellery using a voxel-oriented feature-based Co...

In this project we are working with a security company that is a mayor player in secure alarm transmission. Alarms can be triggered by devices installed at banks, jewelry stores, private homes, etc. As already stated initially, around 90% of alarms are so-called false alarms and are due to technical reasons or unwanted human error. The challenge of our project is to significantly reduce the amo...

Trichloroethylene, a solvent used in a variety of industrial settings for more than 60 years, has caused adverse health effects on the central and peripheral nervous system, the skin, liver, kidney, and heart. Three men have shown relatively unusual manifestations secondary to exposure to trichloroethylene in degreasing operations in the jewelry industry. Toxic encephalopathy, hepatitis, and ca...

We read with interest the article by Ono et al. in which a woman experienced onset of redness, itching, and focal hair loss 3 weeks after clipping surgery of her cerebral aneurysm.[3] It was noted that the four metal pins of the Sugita head holder contain allergens such as cobalt, nickel, chromium, and mercury. It was later determined that the woman had a history of contact dermatitis to metal ...

Transcatheter embolization is increasingly accepted as a safe and effective therapy for acute lower gastrointestinal hemorrhage, but the fate of the coils used for treatment is not entirely known. We report a patient with massive descending colonic bleeding, successfully treated with microcoil occlusion, in whom partially extruded coils were later visualized colonoscopically, but initially misi...

Argyria is a rare disease caused by prolonged skin contact with silver. Localized cases have been described regarding the use of topical medications, and trauma with objects containing this metal such as acupuncture needles and jewelry. Clinically, a macule or a patch, round or oval, appears in the infected area, with a characteristic bluey-gray color. To our knowledge this is the first time th...
