1. Informações sobre aconselhamento genético, acompanhamento e prognóstico de paciente com Síndrome de Rett
Com relação ao aconselhamento genético deve-se informar aos pais que a taxa de recorrência (outro filho com síndrome de Rett) é relativamente pequena comparada com outras síndromes genéticas, sendo de um caso em 300 novas gestações de mães com um filho prévio com a síndrome. (Grau C) A maioria das mutações encontradas na síndrome são muta

2. Participação do óxido nítrico encefálico no controle cardiovascular de rã-touro, Lithobathes catesbeianus
O objetivo do presente trabalho foi determinar se o óxido nítrico (NO) atuando no SNC de rãs apresenta tônus inibitório sobre a pressão arterial média (PAM) e a frequência cardíaca (FC) reduzindo a atividade simpática dependente de receptores a e/ou b adrenérgicos durante o inverno e a primavera/verão. Desta forma, a temperatura corporal e a PAM

3. Profilaxia da fibrilação atrial no pós-operatório imediato de cirurgia coronária: comparação entre propranolol e sotalol utilizados em baixas doses
OBJETIVO: Comparar a eficácia de dois protocolos terapêuticos usando baixas doses de betabloqueadores para prevenção de fibrilação atrial no pós-operatório imediato de cirurgia coronária. MÉTODOS: 154 pacientes, submetidos à cirurgia coronária, foram randomizados em dois grupos: no grupo I (n = 72), os doentes receberam Sotalol (80 mg/dia) e, no

4. A simple HPLC-fluorescence method for the measurement of R,S-sotalol in the plasma of patients with life-threatening cardiac arrhythmias
R,S-sotalol, a ß-blocker drug with class III antiarrhythmic properties, is prescribed to patients with ventricular, atrial and supraventricular arrhythmias. A simple and sensitive method based on HPLC-fluorescence is described for the quantification of R,S-sotalol racemate in 500 µl of plasma. R,S-sotalol and its internal standard (atenolol) were eluted af

5. Acute prolongation of myocardial refractoriness by sotalol.
Sotalol, a beta adrenoceptor antagonist, was given intravenously to 15 patients with accessory atrioventricular pathways during intracardiac electrophysiological studies. Eleven patients had the Wolff-Parkinson-White syndrome and four patients had concealed left sided accessory pathways. Four patients were restudied while receiving oral sotalol. In contrast

6. Electrophysiological effects of sotalol--just another beta blocker?
The electrophysiological effects of intravenous sotalol hydrochloride (0.4 mg/kg) were assessed in 24 patients, including 13 with the Wolff-Parkinson-White syndrome, undergoing routine electrophysiological study. Fifteen to 30 minutes after sotalol administration there was a significant increase in sinus cycle length and in sinus node recovery time. There wa

7. Sotalol, hypokalaemia, syncope, and torsade de pointes.
Thirteen patients developed syncope and a prolonged QTc interval while taking therapeutic doses of sotalol. Polymorphous ventricular tachycardia was observed in 12 patients, and criteria typical of torsade de pointes were present in 10. In 12 patients sotalol had been given with hydrochlorothiazide in a combined preparation, Sotazide, but with inadequate or

8. Beta-adrenoreceptor mechanisms in essential tremor; a double-blind placebo controlled trial of metoprolol, sotalol and atenolol.
In order to elucidate the mode of action of beta-adrenoreceptor antagonists in essential tremor, the efficacy of chronic oral administration of metoprolol, atenolol and sotalol was compared in a randomised, double-blind placebo controlled trial in twenty-four patients. Only sotalol proved superior to placebo on both subjective and "objective" assessments. Me

9. Effect of long term treatment with metoprolol and sotalol on ventricular repolarisation measured by use of transoesophageal atrial pacing.
The effects of long term (4 weeks) treatment with oral metoprolol (100 mg twice daily) and sotalol (160 mg twice daily) on ventricular repolarisation time were compared in a double blind crossover study in 20 patients post-infarction. For QT interval studies transoesophageal atrial pacing was performed at a cycle length of 800 ms. Sotalol prolonged the QT in

10. Intravenous sotalol for the treatment of atrial fibrillation and flutter after cardiopulmonary bypass. Comparison with disopyramide and digoxin in a randomised trial.
The efficacy of sotalol in treating acute atrial fibrillation and flutter after open heart surgery was compared with that of a digoxin/disopyramide combination. Forty adult patients with postoperative atrial arrhythmias were randomised into either group 1 (sotalol 1 mg/kg bolus intravenously plus 0.2 mg/kg intravenously over 12 hours) or group 2 (digoxin 0.7

11. Efficacy of flecainide, sotalol, and verapamil in the treatment of right ventricular tachycardia in patients without overt cardiac abnormality
Objective—A comparison of the efficacy of verapamil, sotalol, and flecainide to suppress right ventricular tachycardia (VT) in patients with a clinically normal heart.

12. Effect of low dose sotalol on the signal averaged P wave in patients with paroxysmal atrial fibrillation.
OBJECTIVE--To investigate the effects of low dose sotalol on the signal averaged surface P wave in patients with paroxysmal atrial fibrillation. DESIGN--A longitudinal within patient crossover study. SETTING--Cardiac departments of a regional cardiothoracic centre and a district general hospital. PATIENTS--Sixteen patients with documented paroxysmal atrial f
