Cluster headache is rare, occurring in less than 1% of the population. Studies suggest that, in addition to the pain and associated autonomic disturbances recognized to be characteristic of the syndrome, patients also may experience nausea, photophobia, behavioral agitation, or restlessness. A decreasing male:female ratio also has been noted, perhaps attributable to lifestyle trends adopted by more women that were previously associated with men, such as tobacco use, alcohol consumption, and working outside of the home. The relationship between cluster headache and hormonal events does not appear to be strong. Hormonal influences on the chronic form of cluster headache in women are a subject of investigation. The emerging understanding of the genetics of cluster headache increasingly suggests a genetic component, with familial transmission now recognized to be more common than previously appreciated. Head trauma, coronary artery disease, and migraine appear to be present in more patients with cluster headache than can be explained by chance alone. Ethnic and racial differences in prevalence are less well understood.

The high-density lipoprotein (HDL)-Atherosclerosis Treatment Study showed that simvastatin plus niacin (mean daily dose 13 mg and 2.4 g, respectively) halt angiographic atherosclerosis progression and reduce major clinical events by 60% in patients with coronary artery disease (CAD) who have low HDL, in comparison with placebos, over 3 years. How safe and well-tolerated is this combination? One hundred sixty patients with CAD, including 25 with diabetes mellitus, with mean low-density lipoprotein cholesterol of 128 mg/dl, HDL cholesterol of < or =35 mg/dl (mean 31), and mean triglycerides of 217 mg/dl were randomized to 4 factorial combinations of antioxidant vitamins or their placebos and simvastatin plus niacin or their placebos. Patients were examined monthly or bimonthly for 38 months; side effects (gastrointestinal upset, nausea, anorexia, vision, skin, and energy problems, or muscle aches) were directly queried and recorded. Aspartate aminotransferase, creatine phosphokinase (CPK), uric acid, homocysteine, and fasting glucose levels were regularly monitored. A safety monitor reviewed all side effects and adjusted drug dosages accordingly. Patients who received simvastatin plus niacin and those on placebo had similar frequencies of clinical or laboratory side effects: any degree of flushing (30% vs 23%, p = NS), symptoms of fatigue, nausea, and/or muscle aches (9% vs 5%, p = NS), aspartate aminotransferase (SGOT) > or =3 times upper limit of normal (3% vs 1%, p = NS), CPK > or =2 times upper limit of normal (3% vs 4%, p = NS), CPK > or =5 times upper limit of normal, new onset of uric acid > or =7.5 mg/dl (18% vs 15%, p = NS), and homocysteine > or =15 micromol/L (9% vs 4%, p = NS). Glycemic control among diabetics declined mildly in the simvastatin-niacin group but returned to pretreatment levels at 8 months and remained stable for rest of the study. This combination regimen was repeatedly described by 91% of treated patients and 86% of placebo subjects as "very easy" or "fairly easy" to take. Thus, the simvastatin plus niacin regimen is effective, safe, and well tolerated in patients with or without diabetes mellitus.

The aim of the study was to evaluate safety and feasibility of dobutamine cardiovascular magnetic resonance (CMR) in patients with proven or suspected coronary artery disease. Dobutamine CMR was evaluated retrospectively in 400 consecutive patients with suspicion of myocardial ischemia. Dobutamine was infused using an incremental protocol up to 40 microg/kg body weight per minute. All anti-anginal medication was stopped 4 days before the CMR study and infusion time of dobutamine was 6 min per stage. Hemodynamic data, CMR findings and side effects were reported. Patients with contraindications to CMR (metallic implants and claustrophobia) were excluded from analysis. Dobutamine CMR was successfully performed in 355 (89%) patients. Forty-five (11%) patients could not be investigated adequately because of non-cardiac side effects in 29 (7%) and cardiac side effects in 16 (4%) patients. Hypotension (1.5%) and arrhythmias (1%) were the most frequent cardiac side effects. One patient developed a severe complication (ventricular fibrillation) at the end of the study. There were no myocardial infarctions or fatal complications of the stress test. The most frequent non-cardiac side effects were nausea, vomiting and claustrophobia. Age >70 years, prior myocardial infarction and rest wall motion abnormalities showed no significant differences with side effects (P>0.05). Dobutamine CMR is safe and feasible in patients with suspicion of myocardial ischemia.

This leading article refers to the paper by Abdelrazeq AS, Owen C, Smith L, McAdam JG, Pearson HJ, Leveson SH. Nicorandil-associated para-stomal ulceration: case series Eur J Gastroenterol Hepatol 2006; 18:1293-1295. We apologise to all concerned for the dissociation between the two papers, which was due to an administrative error. Nicorandil is used widely in patients with coronary artery disease. Nicorandil is well tolerated with only minor side effects. Nicorandil's association with oral, anal, gastrointestinal ulceration, and more recently para-stomal ulceration has been reported. Medical awareness of nicorandil association with ulcerations should be high to help avoid unnecessary and harmful treatment as only cessation of the drug would heal the ulceration. Nicorandil is an antianginal drug used for the treatment of symptomatic coronary artery disease. It is characterized by an arterial and venous vasodilator effect with dual mechanism of action. Nicorandil is not a first-line agent in the management of angina but it is used in combination with other antianginal medications in stable and unstable angina. It is generally well tolerated with minor side effects such as headache, nausea, flushing and dizziness. The association of nicorandil with mouth and anal ulcers as well as the association with ulceration throughout the gastrointestinal tract has been reported, and recently, an association with para-stomal ulceration has also been described. Medical awareness of the association of nicorandil with ulceration in any part of the gastrointestinal tract should be highlighted among all medical professionals to help avoid delays in withdrawing the treatment and to avoid unnecessary and sometimes invasive and costly interventions.

Although cardiovascular mortality for men has been declining, the number of women dying from cardiovascular disease has slightly increased. Differences between women and men have been identified throughout the entire spectrum of ischemic heart disease, from risk factors to presentation and from diagnosis to treatment and outcomes. In the setting of an acute coronary syndrome or acute myocardial infarction, women are significantly more likely than men to report multiple non-chest pain symptoms, including dyspnea, nausea/vomiting, abdominal pain, back pain, neck pain, and jaw pain. Investigations into the pathophysiology of ischemic heart disease in women have broken away from the traditional thinking that coronary artery disease simply equals epicardial stenosis. In women, the new paradigm of coronary artery disease also focuses on diffuse atherosclerosis, endothelial dysfunction, and microvascular disease. Further research focusing on sex differences in cardiovascular disease is needed, but enough is currently known to offer a sex-based approach, which may ultimately lead to improved outcomes.

A continuous infusion of a single high dose of dobutamine has been, recently, suggested as a simple and effective protocol of stress echocardiography. The present study assesses the feasibility, safety, and tolerability of an accelerated dobutamine stress protocol performed in patients with suspected or known coronary artery disease. Two hundred sixty five consecutive patients underwent accelerated dobutamine stress echocardiography: the dobutamine was administered at a constant dose of 50 microg/kg/min for up to 10 minutes. The mean weight-adjusted cumulative dose of dobutamine used was 330 +/- 105.24 microg/kg. Total duration of dobutamine infusion was 6.6 +/- 2.1 min. Heart rate rose from 69.9 +/- 12.1 to 123.1 +/- 22.1 beats/min at peak with a concomitant change in systolic blood pressure (127.6 +/- 18.1 vs. 167.6 +/- 45.0 mmHg). Dobutamine administration produced a rapid increase in heart rate (9.4 +/- 5.9 beats/min2). The side effects were similar to those described with the standard protocol; the most common were frequent premature ventricular complexes (21.5%), frequent premature atrial complexes (1.5%) and non sustained ventricular tachycardia (1.5%); among non cardiac symptoms the most frequent were nausea (3.4%), headache (1.1%) and symptomatic hypotension (1.1%). No major side effects were observed during the test. Our data demonstrate that a continous infusion of a single high dose of dobutamine is a safe and well tolerated method of performing stress echocardiography in patients with suspected or known coronary artery disease. This new protocol requires the administration of lower cumulative dobutamine dose than standard protocol and results in a significant reduction in test time.

Ticlopidine inhibits platelet aggregation and provides beneficial secondary prevention of cerebrovascular and coronary artery disease. Frequently reported adverse effects of ticlopidine include diarrhea, nausea, and rash. However, to our knowledge, there are only a few published reports of the simultaneous occurrence of cholestatic hepatitis and pure red cell aplasia. Here we report a patient with simultaneous severe cholestatic hepatitis and pure red cell aplasia associated with ticlopidine. Although these adverse effects are rare, periodic hematological and liver function tests are recommended after starting ticlopidine.

A coronary artery fistula is a direct communication between a coronary artery and one of the cardiac chambers or vessels around the heart. These fistulas are usually diagnosed by coronary arteriography. Clinical presentations are variable depending on the type of fistula, shunt volume, site of the shunt, and presence of other cardiac conditions. Bilateral coronary fistulas between coronary arteries and the pulmonary artery are very rare. This report describes a 51-year-old man without any previous medical history, who presented to our hospital one hour after the acute onset of severe substernal chest pain associated with shortness of breath and nausea. Coronary angiography revealed two fistulas arising from the left anterior descending and right coronary arteries and draining at exactly the same site in the pulmonary artery. There was no evidence of atherosclerotic coronary artery disease in either the left or right coronary arterial tree.

Takotsubo cardiomyopathy (TC), or "broken heart syndrome", is an increasingly recognized condition that mimics acute myocardial infarction with morphologically characteristic left ventricular dysfunction in the absence of coronary artery disease. TC is seen almost exclusively in postmenopausal women following extreme emotional or physiologic stress. Although most patients present with chest pain, limited data suggest that African American patients with TC tend to present with atypical symptoms such as dyspnea or nausea. We present a 57 year-old African American female with TC who presented with severe dyspnea following the shooting death of her son. Added to existing data, our case alerts clinicians to consider Takotsubo syndrome in African American patients with atypical presentation.

A 55-year-old man presented to the emergency department with a 12-hour history of severe crampy abdominal pain, nausea, vomiting and obstipation. The patient had a complex medical history, including coronary artery disease, lupus, hypothyroidism, epilepsy, pancreatitis and renal calculi. However, the patient had no history of a hernia or abdominal surgery. Physical examination revealed a temperature of 38.5 degrees C and a soft distended abdomen that was diffusely tender without signs of peritonitis. The rest of the physical examination was unremarkable. Routine laboratory investigations including a complete blood cell count, electrolytes, liver enzymes and amylase were normal, with the exception of a decreased hemoglobin level of 116 g/L. We ordered a plain abdominal radiograph (Fig. 1) and a contrast-enhanced computed tomography (CT) scan of his abdomen. What is your diagnosis?
