ABSTRACT
Ethical dilemmas are regularly encountered in the care of patients infected with HIV (Human Immunodeficiency Virus), especially in issues regarding professional confidentiality and shared information with the child and his/her family as well as among professional health workers. This communicable disease, which can be treated but not yet cured, leads to exclusion, due to the fear of infection, to its severity and induces stigmatisation of affected individuals. It interferes with life projects, sexuality, reproductive health, family life, projection into the future. In HIV paediatrics, practitioners regularly deal with complex situations and need to balance parental authority and children's needs/dependence, respect of patient's confidentiality and hazards to another person's health, potential negative impact of disclosing information and risks attributable to the lack of information.

Fatigue is an unexplained but common and disabling symptom in MS. We assessed fatigue in 71 patients with MS and identified MS-fatigue (MSF) and MS-nonfatigue (MSNF) groups. Fatigue severity did not correlate with regional or global MRI plaque load or atrophy assessed by conventional sequences. No significant differences were noted in any MRI measures between MSF and MSNF groups. We suggest that brain MRI disease topography or severity does not explain fatigue in MS and that fatigue is likely due to mechanisms poorly characterized by conventional MRI.

The efficacy and safety of intravenous tocainide were compared with intravenous lidocaine in patients with chronic ventricular arrhythmias in a double-blind, parallel study. Twenty-nine patients were randomized to a tocainide (n = 15) or lidocaine (n = 14) group. Antiarrhythmic efficacy was defined as a greater than or equal to 50% reduction in single ventricular premature complex (VPC) frequency, greater than or equal to 90% reduction in paired VPC frequency, and total abolition of ventricular tachycardia. Efficacy was observed in 40% (6 of 15) of patients in the tocainide group and in 36% (5 of 14) patients in the lidocaine group. A 75% or greater reduction in total VPCs occurred in 40% (6 of 15) of patients in the tocainide group and in 57% (8 of 14) of patients in the lidocaine group. Greater than 90% suppression of paired VPCs occurred in 9 of 13 (69%) patients taking tocainide and in 6 of 11 (54%) patients taking lidocaine. Total abolition of ventricular tachycardia was documented in 5 of 11 (45%) patients given tocainide and in two of six (33%) patients given lidocaine. A total of 17 adverse reactions affecting 86% (12 of 14) of patients taking lidocaine and 11 adverse reactions affecting 53% (8 of 15) of patients taking tocainide occurred. Four patients in each treatment group suffered dose-limiting adverse effects. This study suggests that the efficacy and safety of intravenous tocainide are similar to that of intravenous lidocaine in patients with chronic ventricular arrhythmias.

This single-blind, placebo-controlled study evaluated long-term therapy with cibenzoline in 19 patients with chronic ventricular arrhythmias. Antiarrhythmic efficacy, defined as greater than or equal to 75% reduction in single premature ventricular complexes (PVCs), greater than or equal to 90% reduction in paired PVCs, and total abolition of ventricular tachycardia (VT), was established after dose titration in 14 of 19 (74%) patients. Mean frequency of single PVCs was reduced by 65%, mean paired PVC frequency was reduced by 68%, and mean VT event frequency was reduced by 82%. Antiarrhythmic efficacy was maintained during long-term therapy in five of the 14 (36%) short-term responders. Of the nine patients who discontinued cibenzoline during long-term follow-up, five had a loss of arrhythmia control, three failed to redevelop arrhythmias during placebo reintroduction, and one developed an adverse reaction. Three patients (16%) experienced a proarrhythmic effect. Echocardiographic evaluation did not reveal any deleterious effect of cibenzoline on left ventricular function in the group as a whole. In six patients with preexisting left ventricular dysfunction, left ventricular ejection fraction and fractional shortening improved significantly (P less than .05) during cibenzoline therapy. Adverse effects occurred in seven patients (37%) but necessitated drug discontinuation in only one patient (5%). Cibenzoline provides effective short-term therapy for patients with chronic ventricular arrhythmias. Long-term therapy must be assessed periodically to ensure continued efficacy. Drug-related adverse effects occur infrequently. Cibenzoline can be used safely in patients with compensated left ventricular dysfunction.
