Impact of Thermal Stress on Pulmonary Absorption and Toxicokinetics of 3 Organic Solvents

In Quebec, thousands of workers are concomitantly exposed to heat and chemical compounds. Exposure to heat induces physiological responses that help maintaining a stable body temperature. Those changes can affect organ functions implicated in absorption and metabolism. According to literature, those changes could lead to increased concentrations of chemical compounds in the body and their toxicity. Therefore, the aim of this study is to evaluate the pulmonary absorption and tox...

One Year Clinical Evaluation of Milled BioHPP Polyetheretherketone (PEEK)-Based Versus Metal Ceramic Single Crowns

Although the metal-ceramic system is still widely used to fabricate crowns and fixed partial dentures and is considered as the standard treatment in dentistry, aesthetic concerns have stimulated the development of new dental tooth-colored systems as PEEK. BioHPP PEEK is 20% ceramic reinforced, semicrystalline, thermoplastic and radiolucent polymer for extreme durability especially for frameworks for fixed and removable dental prostheses. It has many advantages as low density, ...


Metal Ion Release From an FDA-Approved Metal-on-Metal Total Hip Replacement Implant

A Multicentre Trial to Compare Two Articulating Bearing Surfaces as Used in Cementless Primary Hip Arthroplasty

The aim of this study is to demonstrate the non-inferiority of the ceramic-on-metal articulation using large diameter bearings (38mm to 60mm) compared to the metal on metal articulation using the same cup in regards to the composite clinical success (CCS) rate at 2 years postoperatively (delta = 10% minimum clinically significant difference in rates).

A Study of AS-101 in Patients With AIDS or AIDS Related Complex (ARC)

To determine the toxic effects of AS-101 at various doses in patients with AIDS or AIDS related complex. Also to determine the effect of various doses of AS-101 on immune functions and the occurrence of infections in these patients. AIDS is a viral disease that is characterized by a loss of some immune function and the development of frequent, eventually fatal, infectious diseases. Although zidovudine (AZT) has prolonged survival in some patients with AIDS, AZT is quite toxic a...

Investigation of Systemic Metal Ion Concentration Following a Ceramic-on-Metal Total Hip Arthroplasty

This is a pilot study to compare systemic concentrations of cobalt and chromium in patients that have previously undergone total hip arthroplasties with ceramic on metal and metal on metal bearing surfaces.

Comparison of Full-arch Implant-supported Frameworks From an Intraoral Scanning or From a Conventional Impression

Purpose: To determine if adjustment of full-arch zirconia frameworks processed on a model obtained with an intraoral scanner and an auxiliary device is not inferior to that of identical frameworks obtained from an elastomeric impression. Materials and methods: Ten consecutive patients ready for a full-arch rehabilitation on already osseointegrated implants were selected. Two sets of impressions were taken, one open tray with polyether and splinted impression copings and a seco...

A Randomised Study to Compare Metal Ion Release and Long-term Performance of the Pinnacle™ Cup With a Ceramic-on-Metal or a Metal-on-Metal Bearing

The purpose of this study is to monitor the performance and compare the metal ion release of two bearing combinations, ceramic-on-metal and metal-on-metal in the treatment of patients with hip joint disease requiring a total hip replacement. Patients who enter the study will be randomly allocated to one of the bearing combinations and will be evaluated at regular intervals using, patient, clinical and x-ray assessments. Patients will also have blood samples taken at regular int...

Study of ABI-007 and Taxol in Patients With Metastatic Breast Cancer

Paclitaxel (Taxol, Bristol-Meyers Squibb) has been shown to be very effective against metastatic breast cancer, as well as other cancers. Because the Taxol formulation of paclitaxel is dissolved in Cremophor, an organic solvent containing castor oil, and ethanol, prolonged intravenous administration times are required; and because the solvent has caused hypersensitivity reactions, a premedication schedule is required. ABI-007 is a new anticancer medication containing the same...

Fibrin Sealant Vascular Surgery Study

The purpose of this study is to evaluate the efficacy and safety of Fibrin Sealant, Vapor Heated, Solvent/Detergent-treated with 500 IU/ml thrombin and synthetic aprotinin (FS VH S/D 500 s-apr) for hemostasis in subjects receiving prosthetic expanded polytetrafluoroethylene (ePTFE) conduits as compared to a control group treated by manual compression with surgical gauze pads.

Organic Diet Intervention in Primary School Children

The study aims to evaluate the hypothesized benefits of a systematic organic diet for children, over those of a conventional diet. The specific objectives of this study are to: i) Demonstrate the decreased body burden of pesticides for those children consuming an organic diet, and ii) Evaluate the effects in specific biomarkers of inflammation and oxidative stress in children systematically consuming an organic diet.

Metal-on-metal Hip Replacement MRI Study

This study is being conducted to determine the rate of symptomatic and asymptomatic nonmalignant, noninfective soft tissue mass presence (referred to in the literature as pseudotumour, ALVAL, ARMD, cysts or lesions) in primary metal on metal hip replacement patients.

The subjects receiving the Metal on Metal devices will be observed a...

Metallosis on Tissues and Serum Metal Levels in Children

Slightly elevated blood metal levels have been found in adults undergoing hip and knee replacement. It is unknown whether pediatric patients with metal implant(plates/screws/rods) have elevated blood metal levels. This may have an impact on practice if children have high blood metal levels with routine orthopedic implants. If researchers find elevated metal levels, they may recommend patients to have the plates removed or may switch to a different type of metal. Further work on...

Midurethral Synthetic Tape With Tension Control Mechanism Versus Midurethral Free Tape
