abstract hydatid disease is caused by echinococcus spp. especially echinococcus granulosus that is the most common cause of hydatid disease in humans. this disease occurs either through direct contact with infected dogs or indirectly from the ingestion of contaminated water or food with eggs of worms. the most common site in human is the liver (59-75%), followed in frequency by lung (27%), kidn...

Reproductive disorders have been found in pesticide-exposed alligators living in Lake Apopka, Florida (USA). These disorders have been hypothesized to be caused by exposure to endocrine- disruptive estrogen-like contaminants. The aim of this study was to expand our analysis beyond previous studies by investigating whether bone tissue, known to be affected by sex steroid hormones, is a potential...

Bacteria may infect the bone directly through open fractures, during bone surgery, or from contaminated objects that pierce the bone. Osteomyelitis may also occur where a piece of metal has been surgically attached to a bone, as is done to repair hip or other fractures. Osteomyelitis may also result from an infection in an adjacent soft tissue. The infection spreads to the bone after several In...

Aluminium balance studies were carried out on eight patients with various immunological disorders who were receiving plasma exchange with albumin solutions known to be contaminated with aluminium. Four patients with impaired renal function (creatinine clearance less than 50 ml/min) retained between 60% and 74% of the aluminium infused during a single plasma exchange. Transiliac bone biopsy spec...

INTRODUCTION Intermittent administration of parathyroid hormone (PTH) promotes oral osseous wound healing and protects against ligature-induced alveolar bone loss. However, its therapeutic value on periapical periodontitis is unknown. The goal of this study was to determine the effect of intermittent PTH administration on the progression of periapical periodontitis. METHODS Seven lymphotoxin ...

BACKGROUND A food borne illness was reported in Ga-East district of Greater Accra Region among school children in May, 2007 after eating food provided at school. The objective of the investigation was to determine the source, mode of contamination and the causative agent. METHODS A case-control study was conducted, cases were schoolchildren with abdominal symptoms and controls were children o...

Bacterial contamination of bone marrow or peripheral blood stem cell transplant products typically occurs with skin flora or, rarely, gram-negative organisms. We describe a clonal outbreak of contamination in transplant products caused by contamination with an aerobic actinomycete that occurred at our institution during the summer of 2001. From 1 July through 12 September 2001, 73 peripheral bl...

BACKGROUND The autograft preparation process for anterior cruciate ligament reconstruction has a potential for graft contamination. The purpose of this study was to evaluate the possibility of contamination of the bone-patellar tendon-bone and hamstring tendon autograft during preparation for anterior cruciate ligament reconstruction. METHODS A primary isolated reconstruction of the anterior ...
