Propafenone-induced liver injury: report of a case and review of the literature.

A case of an acute cholestatic syndrome associated with use of the antiarrhythmic drug propafenone is reported here. The close time relationship between the administration of the drug and the acute onset of the liver damage, the histological findings, and the reappearance of biochemical signs of liver dysfunction upon rechallenge with the same medication strongly suggest that propafenone was involved in the pathogenesis of this syndrome. Although rare, hepatotoxicity from this widely used antiarrhythmic medication should be kept in mind in the differential diagnosis of sudden cholestatic syndrome of obscure origin.

The hyperlactatemic effect of biguanides: a comparison between phenformin and metformin during a 6-month treatment.

To compare the chronic hyperlactatemic effect of phenformin and metformin, we performed a double-blind study in 10 non insulin-dependent diabetics without any other known hyperlactatemic condition. After a pre-study period, each patient was allocated to a 6-month treatment with phenformin (50 mg bid) or metformin (850 mg bid) in random sequence. Body weight values were not significantly different between phenformin and metformin. Diabetic control was significantly (p less than 0.001) improved by both biguanides versus pre-study, but was the same during metformin and phenformin: HbAI = 13.8 +/- 0.3 SEM% during pre-study 9.7 +/- 0.2% during phenformin, 10.2 +/- 0.2% during metformin. Mean values of plasma lactate during metformin were significantly lower versus phenformin (1.30 +/- 0.05 vs 1.64 +/- 0.05 mmol/l, p less than 0.001). Mean values of plasma lactate/pyruvate ratio during metformin were significantly lower versus phenformin (16.92 +/- 0.59 vs 22.65 +/- 0.87, p less than 0.001), but not versus pre-study (16.19 +/- 0.51). These results indicate that: 1) during a 6-month treatment with a diabetic control of similar degree phenformin produces a significantly higher hyperlactatemic effect vs metformin; 2) metformin treatment is associated with less impairment of intracellular redox state versus phenformin, and therefore should be considered advantageous in the long-term treatment of non insulin-dependent diabetics.

[Endobronchopulmonary therapy with a permanent trans-crico-thyroid probe].

The possibilities of treating chronic bronchopneumopathies of various nature by means of permanent endobronchial transcricothyroid probe are examined with reference to 6 cases representing patients under treatment at the time this paper was being prepared (2 cases of chronic pulmonary TB, 2 of suppurating bronchiectasis, 1 of middle lobe syndrome and 1 of tracheal carcinoma). The series examined confirms the usefulness of this type of treatment as a back-up to traditional medical treatment where this alone failed to achieve the necessary results. Stress is laid on the good tolerance of the TCT probe presented by all patients, including a five-year-old boy.

Natural and acquired inhibitors of hemostasis in selected symptomatic outpatients with venous thromboembolic disease.

BACKGROUND AND OBJECTIVE: Deficiencies of natural inhibitors and the presence of lupus anticoagulant are important risk factors leading to venous thromboembolic events. Before resistance to activated protein C (APC-R) was identified, the overall prevalence of inherited abnormalities of hemostasis in non-selected outpatients with venous thromboembolic disease was under 10%. This cast doubts on the of cost effectiveness and clinical significance of assaying hemostasis inhibitors in all such patients. The goal of this study is to evaluate the prevalence of inherited and acquired abnormalities of hemostasis in younger symptomatic outpatients with objectively diagnosed venous thromboembolic disease (VTD). METHODS: From October 1994 to October 1996, we diagnosed, treated and followed 191 consecutive outpatients with an objective diagnosis of venous thromboembolic disease, and assayed natural and acquired hemostasis inhibitors in 81 of them aged less than 50; in addition, 129 relatives of patients with inherited deficiencies were evaluated. RESULTS: Twenty-six of the patients under age 50 showed inherited deficiencies of natural inhibitors (3 antithrombin, 5 protein C, 3 protein 5 and 14 APC-R, 1 dysfibrinogenemia) and 8 patients had lupus anticoagulant (LA): abnormalities of hemostasis were found in 41.9% (95% confidence interval 31.1-53.5). In older selected patients, 60% (95% confidence interval 40.6-77.3) of the subjects showed abnormalities. Seventy-two of the relatives displayed natural inhibitor deficiencies; 88.5% of the families studied had at least one relative with the same defect as the propositus. INTERPRETATION AND CONCLUSIONS: A simple selection based on age, clinical and family history shows the existence of a high prevalence and the important clinical significance of abnormalities of hemostasis in symptomatic outpatients with venous thromboembolic disease.
