AAHA dental care guidelines for dogs and cats.

The purpose of this document is to provide guidelines for the practice of companion animal dentistry for the veterinary profession. Dental care is necessary to provide optimum health and quality of life. Diseases of the oral cavity, if left untreated, are often painful and can contribute to other local or systemic diseases.

Comparison of hand-instrumented, heated gutta-percha and engine-driven, cold gutta-percha endodontic techniques.

An in vitro study compared two gutta-percha obturation techniques of the mandibular first molar in dogs. The mandibular first molars were instrumented and obturated using either K-files and the SuccessFil vertical compaction technique or rotary instruments and the Simplifill/guttapercha master cone technique. Instrumentation and obturation times were recorded for each tooth.

[Left ventricular thrombus revealed by electron bean computed tomography, in a patient with antiphospholipid syndrome].

The authors report a case of a 48 year old woman admitted to hospital because of digital ischemia, in a context of antiphospholipid syndrome. The electrocardiogram-triggered electron beam computed tomography revealed an apical thrombus associated with a thinning left ventricular wall, suggesting painless myocardial infarction. The diagnosis was secondary confirmed by coronarography.

Arterial lesions in Behçet's disease. A study in 25 patients.

Objective: To identify the prognostic indicators of patients with Behçet's disease complicated with arterial lesions.

Methods: Retrospective chart analysis of 25 consecutive patients with Behçet's disease and angiographically proven arterial lesions.

Results: Occlusive lesions were present in 7 patients, aneurysms in 3, and both occlusive and aneurysmal lesions in 15.

Adjusted versus fixed doses of the low-molecular-weight heparin fragmin in the treatment of deep vein thrombosis. Fragmin-Study Group.

Treatment monitoring based on a laboratory parameter increases the efficacy and safety of standard heparin therapy, but it is not known if this also applies to low-molecular-weight heparin (LMWH) therapy of acute deep vein thrombosis (DVT). In a prospective randomized trial involving 122 consecutive patients, group A (58 patients) received a weight adjusted dose of Fragmin (100 IU/kg) subcutaneously twice a day throughout the treatment period (10 days +/- 1), while in group B (64 patients) the dosage was based on the results of an anti factor Xa (anti Xa) amidolytic assay to obtain a target concentration from 0.5 to 1 IU/ml.
