[An outpatient regimen for dental improvements in patients with valvular cardiopathies and oral anticoagulant therapy (a preliminary note)].
The purpose of this paper is to verify the level of confidence of a new approach to the management of patients with cardiovalvular prosthetic and oral treatment with anticoagulants during high level risk oral surgery procedures. The new protocol includes: interrupted oral anticoagulant treatment; ambulatory regimen instead of hospital regimen; special dentistry management. No hemorrhagic complications occurred in the study sample. This paper concludes with a review of the role of Quick test in the management of patients with cardiac prostheses.
Different pre-treatment processes were applied to investigate the removal of chemical oxygen demand (COD) from paper mill effluent. The objective of this paper is to find the optimal operating conditions for coagulation process. The effect of key operational parameters, including the type of coagulant, initial pH, temperature, and coagulant dose, on the percent removal of COD was investigated. Under the optimal operational conditions, the treatment of wastewater from paper industries by coagulation has led to a reduction of fee paid for wastewater discharged.
