Habit reversal training in children and adolescents with chronic tic disorders: an Italian randomized, single-blind pilot study.

BACKGROUND: The aim of the present study was to test the possibility to apply habit reversal training (HRT) in Italy and to evaluate the effectiveness of HRT in reducing tic severity compared with the "usual care" (UC) in Italian children and adolescents with Tourette Syndrome. METHODS: We performed a single blind, randomized, pilot study comparing HRT (active treatment) and UC (usual treatment). Out of 69 patients seen during the study period, we were able to enroll 21 patients (11 randomized to HRT e 10 to UC). Assessment included in-depth neurological and psychiatric examination, K-SADS-PL, YGTSS, KIDSCREEN, GTS-QOL, CGI and C-GAS. All these evaluations but the K-SADS-PL were used for baseline assessment but also one week after the end of treatment (T1) and then 3, 6 and 9 months later (respectively T2, T3, and T4). RESULTS: The sample was largely composed of patients of relevant clinical severity (CGI≥3: 85%). OCD and ADHD were the most frequent comorbidities (30% each). Only minor differences in terms of treatment effectiveness were found, although the HRT group turned out to include patients with more tics and a more compromised general functioning despite randomization. CONCLUSIONS: We had a high number of patients who refused to be randomized (23 out of 69) and a high number of drop outs (27% in the HRT group, 50% in the UC group). There was an improvement in terms of reduced tics and improved global functioning in both groups, without significant changes in terms of Quality of Life.

Effects of nebivolol versus carvedilol on left ventricular function in patients with chronic heart failure and reduced left ventricular systolic function.

BACKGROUND: Beta-adrenoceptor antagonist (beta-blocker) therapy results in a significant improvement in left ventricular (LV) systolic function and prognosis in patients with chronic heart failure. Both carvedilol and nebivolol produce hemodynamic and clinical benefits in chronic heart failure, but it is unknown whether their peculiar pharmacologic properties produce different effects on LV function. OBJECTIVE: To assess the effects on LV function of nebivolol compared with carvedilol in patients with chronic heart failure and reduced LV systolic function. METHODS: Seventy patients with a LV ejection fraction

Embolic stroke, sinus rhythm and left atrial mechanical function.

A 64-year-old man manifested a stroke two years after restoration of sinus rhythm through a radiofrequency catheter ablation. Transesophageal echocardiography demonstrated the presence of a thrombus in the left atrial appendage. Left atrial volumes and different parameters of atrial emptying showed that, despite the persistence of the sinus rhythm, atrial mechanical function was severely impaired. After atrial ablation procedures echocardiography can be useful to stratify patients according to their risk of developing embolic events and hence be of help in deciding whether or not discontinuation of anticoagulant therapy is the appropriate choice.
