Dental extraction in hemophiliacs with acquired inhibitors is always a risky procedure, which often presents a lot of problems associated with bleeding. A known case of hemophilia A complicated with factor VIII inhibitors and having odontogenic infection was successfully managed by transfusion of factor VIII inhibitor bypass activity (FEIBA) and antihemophilic factor. Past medical history was s...

Relationship or Epiphenomenon of Sedentary Lifestyle? To the Editor: Doggen et al report that low HDL cholesterol and high triglyceride levels are associated with an increased risk for venous thrombosis in a population-based case–control study. The authors explain their results with an interaction of triglycerides with different coagulant factors as activated protein C (APC), factor VIIc, facto...

BACKGROUND AND OBJECTIVES A high level of coagulant factor VIII is a well known risk factor for venous thromboembolism, but most studies have enrolled patients under 70 years old. This study aimed to test the hypothesis that an association also exists in the elderly. DESIGN AND METHODS This hospital-based case-referent study took place at the Department of Internal Medicine and Chest Diseases...

The need to ameliorate some of the inherent limitations in the use of alum in water purification engendered these studies. Synthetic water of varying turbidities (50, 100, 300 NTU) and varying pHs (2, 3, and 4), but low alkalinity were prepared. The results from the different studies showed that water of lower residual turbidity could be got from the use of 50% of optimum alum dose when combine...

Issam Najm, Carol Tate, and Douglas Selby he upcoming Disinfectants/Disinfection ByProducts (D/DBP) Rule recognizes that a greater reduction in the total organic carbon (TOC) concentration of a natural water supply may appreciably reduce the concentrations of known and unknown DBPs formed during chlorination. Thus, the D/DBP Rule requires that conventional surface water treatment plants use enh...

In this study arsenate [As(V)] removal from drinking water by coagulation process was investigated. Ferric chloride (FeCl3.6H2O) and ferrous sulfate (FeSO4.7H2O) were used as coagulant. The effects of major operating variables such as coagulant dose (1–30 mg/L) and pH (5.5–9.5) were investigated. Ferric chloride and ferrous sulfate were found as effective and reliable coagulant due to required ...
