RESUMEN
To evaluate the efficacy and safety of low dose (10 mg) pravastatin in hypercholesterolemic, hypertensive elderly subjects undergoing antihypertensive treatment, a randomized, double-blind, placebo-controlled 6-month trial was conducted. The subjects had a total plasma cholesterol of at least 250 mg/dL and had been, for at least 3 months, consuming a standard lipid-lowering diet (American Heart Association Step 1 Diet). Sixty elderly hypertensive patients randomly received placebo (n = 30) or pravastatin (n = 30) treatment. The dosage consisted of 10 mg of pravastatin daily during the 6-month trial. Over that period, in the pravastatin group, plasma levels of total cholesterol and LDL-cholesterol significantly (P < .01) dropped (-20% and -25%, respectively) compared to the placebo group. The plasma level of HDL-cholesterol increased (+5%) while triglycerides slightly decreased (-8%) (P < .05). No serious side effects occurred, and pravastatin was generally tolerated. Fasting hyperinsulinemia (11.0 +/- 0.8 v 9.3 +/- 0.7 microU/mL; P = .06) also improved, although not significantly, after 6 months of pravastatin therapy. Results from this study confirmed that a low dose (10 mg) of pravastatin daily is a safe and effective method of reducing plasma total and LDL-cholesterol in hypercholesterolemic, hypertensive elderly patients who are on concurrent antihypertensive drug therapy.

This study compared the incidence of cough with the angiotensin-converting enzyme (ACE) inhibitor lisinopril and the diuretic metolazone with angiotensin II receptor antagonist losartan in elderly hypertensive patients with previous histories of ACE inhibitor-induced cough. A randomized, double-blind, stratified, parallel-group comparison of lisinopril at 10 mg, losartan at 50 mg, and metolazone at 1 mg, each given once daily for a maximum of 10 weeks, was performed in four hypertension clinics in four centers in two countries. Cough was detected by a questionnaire (the primary end point) given to elderly patients with hypertension, and the cough frequency was quantified by a visual analog scale (a secondary end point). A total of 84 elderly patients with hypertension, all who were nonsmokers with ACe inhibitor-induced cough and were confirmed by lisinopril rechallenge then placebo dechallenge, were randomized to the three treatment groups. The incidence of cough with losartan (18%) was significantly lower than with lisinopril (97%) and similar to that for metolazone (21%). Cough frequency evaluated by the visual analog scale was significantly lower for losartan than for lisinopril and similar to that for metolazone. The specific, selective angiotensin II receptor antagonist losartan is associated with a decrease in the incidence of cough in patients with previous ACE inhibitor-induced cough.

Five patients with cardiovascular disease presented with hoarseness due to left recurrent laryngeal nerve palsy. One had secundum atrial septal defect, one had ventricular septal defect, two had mitral stenosis and the other had aortic aneurysm. All except the patient with aortic aneurysm had pulmonary artery dilatation and moderate to severe pulmonary hypertension. Four patients' hoarseness resolved after successful interventional therapy. As for the patient with the aortic aneurysm, hoarseness persisted; the patient died before surgery. We postulate that the dilated pulmonary artery or aortic arch was responsible for the compression of the left recurrent laryngeal nerve.

A 34-year-old man came to this Emergency Room because of fever, swelling and pain in the right thigh. Tetralogy of Fallot with bicuspid pulmonary valve was diagnosed after serial examination, and computed tomography of the right thigh revealed pyogenic myositis. Surgical drainage of the right thigh abscess and a further pus culture yielded viridans streptococci. There has been no record in the medical literature of a pyogenic myositis caused by viridans streptococci in an adult tetralogy of Fallot. This is thus the first case reported.

Cardiovocal syndrome is a rare clinical diagnosis that signifies vocal cord palsy associated with various cardiovascular diseases. The radiological manifestations of six cases of clinically diagnosed cardiovocal syndrome are reviewed retrospectively. The common clinical presentation of these six cases was hoarseness that was due to left vocal cord palsy. By means of chest X-rays (CXR) and cardioangiography, four cases were respectively diagnosed to have atrial septal defect (n = 1), ventricular septal defect (n = 1) and mitral stenosis (n = 2), all of which were associated with a common radiological finding of dilatation of pulmonary trunk. The other two cases were separately diagnosed to have proximal descending aortic saccular aneurysm (n = 1) by means of CXR and angiography, and fusiform ascending aortic aneurysm (n = 1) by computed tomography and magnetic resonance image. All these radiological presentations of either aortic aneurysm or dilated pulmonary trunk were associated with encroachment of aorticopulmonary window for which the left recurrent laryngeal nerve was presumably compressed with the result of left vocal cord palsy. Hoarseness that is caused by these underlying cardiovascular diseases is correctable after treatment of the underlying diseases. Hence, clinicians and radiologists should pay attention to the radiological manifestations of patients whose chief complaints are hoarseness and cardiovocal syndrome.
