In case of blast injuries, traumatic tattoos can result from accidental inclusions of intradermal pigmented particles. To avoid these tattoos, especially in esthetical areas like the head and neck region and the hands, the primary goal in our treatment is to remove all particles and foreign bodies. Superficial foreign bodies can easily be removed by brushes or dermabrasion. Deeper lesions are a...

The sterile sponges may lose a significant amount of lint during their routine use in surgery, which is usually neglected. We designed an experimental model to evaluate the potential of sterile sponges to lose lint and to induce foreign body reaction in surgically created wounds. In 15 Wistar rats, separate subcutaneous pockets were created. Left-sided pockets were temporarily packed with steri...

The Automatic Liquid Particle Inspection Machine (AIM) using 2-D Tsallis Entropy with modified pulsecoupled neural networks (PCNN) is used in order to detect visible foreign particles within injection fluids. According to the motion of the particles in liquid, appropriate mechanisms are utilized which guarantees that the inspection machine will follow detection procedures: ‘‘Rotation, Abruptly ...

The theory of contact mechanics deals with stresses and deformations which arise when the surfaces of two solid bodies are brought into contact. In elastic deformation contact occurs over a finite area. A regular method for determining the dimensions of this area is Hertz Contact Model. Appearance of atomic force microscope results in introduction of Contact ...

Corn starch particles are used as a surgical glove lubricant. At present there is no better alternative for this lubricant. Implantation of corn starch particles into the peritoneal cavity can induce foreign body reactions, starch peritonitis and starch granulomata, and may cause adhesions and intestinal obstruction. Starch peritonitis should be treated conservatively.

OBJECTIVE To assess the presence of foreign material in the granulomatous cutaneous lesions of patients with systemic sarcoidosis. DESIGN AND SETTING Observational study reevaluating histological specimens at a university referral hospital. PATIENTS Sixty-five patients diagnosed as having sarcoidosis who developed granulomatous cutaneous involvement. MAIN OUTCOME MEASURES To detect the pr...

1. Small particles essentially similar to those previously isolated from other tissues have been isolated from mammalian red blood cells (horse blood). 2. About one-third of the dry weight of the particles is lipids. 3. The particles produce hemolysins against the homologous erythrocytes when inoculated into a foreign species. 4. The fact that the particles can be isolated from mammalian red ce...
