25. Trombose venosa cerebral: evolução clínica e fatores prognósticos em 111 pacientes / Cererbal venous thrombosis: clinical outcome and prognostic factors in 111 patients
Introduction: The cerebral venous thrombosis (CVT) clinical evolution is quite variable from complete recovery to death. Some European series and a multicenter study had identified prognostic factors related to CVT prognosis. The identification of these factors is important for the best therapeutic decision to patients. This study aims to identify the progno

27. Hematoma intramural duodenal como complicação de terapia anticoagulante com Warfarin: relato de caso e revisão da literatura
Relatamos o caso de uma paciente em terapia anticoagulante oral com Warfarin, apresentando obstrução intestinal aguda. A tomografia computadorizada revelou hematoma intramural duodenal. O tratamento baseou-se na correção das provas de coagulação e medidas expectantes. Este caso ilustra o valor da tomografia computadorizada e da abordagem conservadora n

28. Trombose de seio venoso cerebral e trombose sistêmica associadas à mutação do gene 20210 da protrombina: relato de caso
Trombose venosa cerebral é entidade de grande gravidade se não identificada e tratada precocemente. As etiologias são diversas e seu reconhecimento pode ditar o tratamento e o prognóstico dos pacientes. Mutações genéticas têm sido envolvidas, principalmente a mutação do gene 20210 da protrombina. Relatamos o caso de homem, 53 anos, admitido em esta

29. Sildenafil no tratamento da hipertensão pulmonar associada a lúpus eritematoso sistêmico e síndrome antifosfolipídio
Hipertensão pulmonar grave é uma doença debilitante, com expectativa de vida reduzida, que acomete adultos jovens. Complicações pleuropulmonares no lúpus eritematoso sistêmico ocorrem em 50% a 70% dos pacientes. A hipertensão pulmonar grave no lúpus eritematoso sistêmico é rara e tem prognóstico reservado. Descreve-se, pela primeira vez, um pacie

30. Evaluation of the marker of hypercoagulability prothrombin fragment F 1+2 in patients with mechanical or biological heart valve prostheses
OBJECTIVE: To investigate whether patients with heart valve prostheses and similar International Normalized Ratios (INR) have the same level of protection against thromboembolic events, that is, whether the anticoagulation intensity is related to the intensity of hypercoagulability supression. METHODS: INR and plasma levels of prothrombin fragment 1+2 (F1+2)

31. Warfarin STEREOCHEMICAL ASPECTS OF ITS METABOLISM AND THE INTERACTION WITH PHENYLBUTAZONE
An examination of the metabolic fate of the R and the S isomers of warfarin revealed that the two isomers were metabolized by different routes. R warfarin was oxidized to 6-hydroxywarfarin and was reduced to the (R,S) warfarin alcohol. In contrast, S warfarin was oxidized to 7-hydroxywarfarin and was reduced to the (S,S) warfarin alcohol. S warfarin was also

32. Stereoselective Interaction of Phenylbutazone with [12C/13C]Warfarin Pseudoracemates in Man
To evaluate the interaction of phenylbutazone with racemic warfarin or R,S-(±)-warfarin in man, S-(−)-warfarin or levowarfarin was synthesized with 13C label in the 2-position of the coumarin nucleus and added to [12C]R(+)-warfarin or dextrowarfarin to form a [12C/13C]pseudoracemate of warfarin. In six normal human subjects, a single oral dose of this “

33. Dichotomal Effect of the Coumadin Derivative Warfarin on Inflammatory Signal Transduction
Warfarin, a widely prescribed drug for preventing thrombosis, is thought to act solely through inhibition of vitamin K-dependent coagulation factors. Low concentrations of warfarin inhibit interleukin-6 production and phosphorylation of I-κB but not activation of p38 mitogen-activated protein kinase. Thus, warfarin inhibits inflammatory signal transduction,

34. Factors affecting the maintenance dose of warfarin.
AIM: To identify the possible factors determining the dose of warfarin prescribed in patients receiving anticoagulant treatment. METHODS: The computerised records of 2305 patients maintained on the drug in seven hospitals were amalgamated and classified into one of seven diagnostic groups. The associations with the dose of warfarin prescribed were investigat

35. The congenital warfarin syndrome: a case report.
A case is reported of a baby born with congenital abnormalities due to maternal ingestion of warfarin during pregnancy. Warfarin is known to be teratogenic, producing characteristic abnormalities, namely a hypoplastic nose, stippled epiphyses, and skeletal abnormalities. A variety of ocular abnormalities have been reported. Ophthalmologists should seek a his

36. Effect of warfarin on the induction and course of experimental endocarditis.
The effect of warfarin treatment on an experimental endocarditis was studied in rabbits. Warfarin had no effect on the induction of a Streptococcus sanguis infection in catheter-induced endocardial vegetations, and the course of this infection was also unaltered. However, warfarin treatment resulted in rapidly progressive bacteremia, probably due to impaired
