Aseptic loosening and osteolysis are considered the main long-term problems of hip arthroplasty. Pathogenesis of periprosthetic osteolysis is multifactorial, and both the biological and mechanical factors seem to play an important role. Bearing surfaces continuously generate excessive amounts of micron and submicron particles provoking an adverse(More)
An 11-months-old male Golden Retriever occasionally found to have Ixodes ricinus ticks attached to the skin developed the acute onset of fever, lameness and inappetence followed by rapidly progressive depression, ataxia and reluctance to move. Inclusions (morulae) were observed in granulocytes. The blood analysis revealed severe thrombocytopoenia,(More)
PURPOSE The aim of this study was to compare CT findings of adrenal incidentalomas with a definitive histological diagnosis in order to establish CT features characteristic for individual types of lesions. PATIENTS AND METHODS The retrospective study comprised of patients with adrenal lesions detected on abdominal CT. The patients with these incidental(More)
BACKGROUND Dental materials, oral hygiene products and food additives may cause contact allergic reactions in the mouth with varied clinical presentation. Oral lichenoid lesions (lichen planus-like lesions) can be induced by hypersensitivity to dental restorative metals, acrylates, flavorings and other substances. AIM The aim of this study was to(More)
The terminal reparative phase was studied in wounds caused by carbon dioxide laser on rat skin, auricle, striated muscle, liver and spleen. Comparative histology was especially concerned with resorptive granulomas around carbonized tissue remnants. Presence of carbonized residua was connected with a more extensive fibrosis and seemed to lengthen the healing(More)
The authors present a rare case of double skin tumors: acral lentiginous melanoma and metatypical carcinoma. The tumors were manifested as gradually enlarging ulcerations on the leg and sole of the foot that did not respond to standard treatment. The skin biopsies showed advanced acral lentiginous melanoma on the sole and metatypical carcinoma of the lower(More)
BACKGROUND There are only 4 unequivocal cases of metastasizing middle ear carcinoid previously reported. OBJECTIVE To present a case of metastasizing middle ear carcinoid, to review previously reported cases, and to discuss the clinical nature of this tumor, which is similar to "orthotopic" carcinoids bearing definite metastatic potential. STUDY DESIGN(More)
Expression of the bcl-2 gene has been shown to effectively confer resistance to programmed cell death in a variety of tumors. The bcl-2 proto-oncogene is involved in the development of human follicular lymphomas and also in a number of solid tumors such as carcinomas of prostate, breast, lung and GIT. The present study was designed to analyze the role of(More)
A total of 21 transitional carcinomas of the urinary bladder were examined by the method of indirect immunoperoxidase reaction using anti-H monoclonal antibody. Expression of blood group H antigen was detected in ten cases but no association with the grade of differentiation of the tumor tissue was established. The prognosis of carcinomas expressing blood(More)
