The objective was to improve understanding of adverse events occurring with celecoxib in the treatment of osteoarthritis and rheumatoid arthritis. Data were extracted from company clinical trial reports of randomised trials of celecoxib in osteoarthritis or rheumatoid arthritis lasting 2 weeks or more. Outcomes were discontinuations (all cause, lack of efficacy, adverse event, gastrointestinal adverse event), endoscopically detected ulcers, gastrointestinal or cardio-renal events, and major changes in haematological parameters. The main comparisons were celecoxib (all doses) versus placebo, paracetamol (acetaminophen) 4,000 mg daily, rofecoxib 25 mg daily, or nonsteroidal anti-inflammatory drugs (NSAIDs) (naproxen, diclofenac, ibuprofen, and loxoprofen). For NSAIDs, celecoxib was compared both at all doses and at licensed doses (200 to 400 mg daily). Thirty-one trials included 39,605 randomised patients. Most patients had osteoarthritis and were women of average age 60 years or above. Most trials lasted 12 weeks or more. Doses of celecoxib were 50 to 800 mg/day. Compared with placebo, celecoxib had fewer discontinuations for any cause or for lack of efficacy, fewer serious adverse events, and less nausea. It had more patients with dyspepsia, diarrhoea, oedema, more adverse events that were gastrointestinal or treatment related, and more patients experiencing an adverse event. There were no differences for hypertension, gastrointestinal tolerability, or discontinuations for adverse events. Compared with paracetamol, celecoxib had fewer discontinuations for any cause, for lack of efficacy, or diarrhoea, but no other differences. Compared with rofecoxib, celecoxib had fewer patients with abdominal pain and oedema, but no other differences. Compared with NSAIDs, celecoxib had fewer symptomatic ulcers and bleeds, endoscopically detected ulcers, and discontinuations for adverse events or gastrointestinal adverse events. Fewer patients had any, or a gastrointestinal, or a treatment-related adverse event, or vomiting, abdominal pain, dyspepsia, or reduced haemoglobin or haematocrit. Discontinuations for lack of efficacy were higher. No differences were found for all-cause discontinuations, serious adverse events, hypertension, diarrhoea, nausea, oedema, myocardial infarction, cardiac failure, or raised creatinine. Company clinical trial reports present much more information than published papers. Adverse event information is clearly presented in company clinical trial reports, which are an ideal source of information for systematic review and meta-analysis.

A community-based study of 425 older African Americans assessed whether their knowledge and behaviors were consistent with current recommendations regarding out-of-hospital sudden heart attack. More than 90% of the study participants were able to recognize major symptoms of sudden heart attack such as chest pain, shortness of breath, weakness, fatigue, fainting, and sweating, and, to a lesser extent, atypical pain, nausea, lightheadedness, and unexplained anxiety. When asked what they would do first in case they witness sudden heart attack, 97% responded that they would call emergency medical services. In contrast, of the participants who actually witnessed sudden heart attack, 80% called emergency medical services, whereas 20% waited to see if the symptoms would go away; called a neighbor, relative, or a friend before contacting emergency medical services; or took the victim to the hospital. These findings show that reported behavioral intentions were satisfactory, but actual bystanders' actions were not always consistent with current recommendations regarding sudden heart attack.

Patients with an untreated myocardial infarction may present with serious late complications. 3 patients are described. A 63-year-old woman became progressively more short of breath 4 days after an acute episode of chest pain accompanied by nausea and sweating. It proved to be a cardiogenic shock following a rupture of a papillary muscle. A man aged 65 collapsed 5 days after an episode of back pain and nausea. This was a cardiac tamponade due to rupture of the left ventricle. A woman aged 74 had transient aphasia and during investigations for this was seen to have anomalies on ECG. She had cerebral emboli and a cardiac aneurysm with associated thrombus. All 3 patients recovered following mitral-valve replacement, repair of the rupture and medicinal treatment for the clot, respectively. Around one-third of patients who have a myocardial infarction do not have chest pain but experience shortness of breath, autonomic nervous symptoms (sweating, nausea, vomiting), extreme and inexplicable tiredness and fainting. These atypical symptoms should suggest myocardial infarction. In order to avoid high morbidity and death from complications such as arrhythmias, heart failure, rupture and aneurysm formation it is important that a patient who has had a myocardial infarction should be treated as soon as possible, preferably by reperfusion therapy.

The TNFalpha inhibitor infliximab is widely used in the treatment of rheumatoid arthritis and Crohn disease. Mild infusion reactions consisting of low-grade fever, headache, nausea, and fatigue are common, but we describe for the first time the occurrence of an acute coronary syndrome during infliximab administration. This case alerts infusion centers to consider the possibility that chest pain and dyspnea during infliximab infusion can represent a myocardial infarction, even in younger patients without a history of cardiac disease.

In addition to its U.S. Food and Drug Administration (FDA) approved conditions, immune globulin intravenous (IGIV) is now being used to treat a vast array of autoimmune disorders. Some of the reasons for this overall increase in the use of IGIV include its effectiveness and safety. Despite many years of safe use, side effects and adverse reactions still occur. Common and mild side effects associated with IGIV include: headache, malaise, nausea, low-grade fever, urticaria, arthralgias, and myalgia. These symptoms typically resolve within a few days after their onset. Although rare, the serious and potentially fatal side effects include: anaphylactic reactions, aseptic meningitis, acute renal failure, stroke, myocardial infarction, and other thrombotic complications. Many of these side effects have occurred in patients who have significant, underlying risk factors for the development of the event. Thus, it is vitally important that a thorough and comprehensive medical evaluation be performed on every patient who is being evaluated for potential IGIV therapy. This evaluation can, to some extent, significantly minimize the risk of these side effects. Careful, constant, and close monitoring by trained personnel during the infusion can also result in early detection of such events. Physicians should thoroughly discuss the risks and benefits of IGIV with patients who are being considered for this therapy.

The European Society of Cardiology and the American College of Cardiology redefined the concept of myocardial infarction in the presence of highly positive markers of myocardial injury associated with at least one of the following: ischemic symptoms; development of pathologic Q waves on the ECG or ECG changes indicative of ischemia (positive or negative deviation of the ST segment), making troponins one of the most important aspects in the evaluation and stratification of patients with chest pain in the emergency room. However, although troponin gives excellent accuracy in the identification of myocardial necrosis, it is known that it can also be elevated in a series of nonatherosclerotic heart diseases. We present the case of a 49-year-old female patient admitted to the Chest Pain Unit with a history of supraventricular tachycardia associated with chest discomfort, nausea and diaphoresis. During risk stratification, the patient presented with a high serum troponin T level (0.143 ng/ml) but with a normal coronary angiography.

Internal hernia is an unusal cause of intestinal obstruction. Herniation related to epiploic appendix is a very rare entity. We herein report a case of internal herniation due to an adhesion between epiploic appendixes and the greater omentum. A 71-year-old woman complaining of abdominal pain and intermittent nausea was operated on with the pre-operative diagnosis of intestinal obstruction. Three epiploic appendixes of the left side of the transverse colon and the corresponding part of the greater omentum had created a tunnel and a loop of small bowel 25 cm in length was strangulated. No resection was required after releiving the strangulation. However, the patient died due to massive myocardial infarction in the postoperative period. Internal herniation must be included in the differential diagnosis of patients with acute abdomen or intestinal obstruction. A high index of suspicion with prompt surgical intervention may be the key to the reduction of morbidity and mortality.

Rizatriptan and zolmitriptan are both used to relieve acute migraine and cluster headaches. The mechanism of action is similar to the other triptans, in that they reverse abnormal cerebral vasodilation through their activity as 5-HT1B receptor agonists. Triptan-induced vasoconstriction is attributed to its activity on peripheral 5-HT1B receptors and has rarely been reported to result in stroke, myocardial infarction and ischemic colitis. We present two cases of renal infarction associated with therapeutic triptan use. The first patient is a 57-year-old man with a history of hypertension that was well controlled on valsartan and hydrochlorothiazide. He was recently diagnosed with cluster headaches and was treated with indomethacin, prednisone, butalbital-acetaminophen-caffeine and hydrocodone without relief. He then received two therapeutic doses of rizatriptan on each of the two days prior to presentation. Subsequently, he presented to the emergency department complaining of nausea, vomiting and right-sided abdominal pain. A computerized tomography (CT) scan of the abdomen and pelvis with intravenous contrast revealed a very large wedge shaped infarction of the right kidney. The second patient is a 34-year-old man with a past medical history significant only for life-long migraine headaches successfully treated for the past six years with zolmitriptan. Shortly after taking one therapeutic dose of zolmitriptan, he presented to the emergency department complaining of nausea and left-sided abdominal pain. A CT scan of the abdomen and pelvis with intravenous contrast revealed multiple wedge-shaped infarctions of the left kidney. Renal infarction was confirmed in both patients by arteriogram of the renal arteries. Although both rizatriptan and zolmitriptan are effective in the treatment of migraine and cluster headaches, they may induce peripheral vasospasm leading to renal infarction.

(1) For patients aged over 60 years who have essential thrombocythaemia, and are considered to be at increased risk of thromboembolism, the standard cytotoxic agent is hydroxycarbamide (hydroxyurea), which reduces the risk of thrombocytosis but adversely affects other blood cell lines. It may also increase the risk of progression to cancer. (2) Anagrelide, initially studied as an antiplatelet drug, was approved in Europe for the treatment of essential thrombocythaemia in high-risk patients when other treatments fail or are poorly tolerated. (3) Evaluation data includes a trial versus hydroxycarbamide that was prematurely halted because of an excess of cardiovascular events among patients on anagrelide. Among 809 patients who were also receiving aspirin as an antithrombotic (and who may not have met strict criteria for essential thrombocythaemia), arterial or venous thrombosis and haemorrhage were significantly more frequent with anagrelide, during a median follow-up of 39 months (55 versus 36 patients). (4) According to the results of 3 non comparative trials involving about 500 patients, and the European Medicines Agency report analysing these and other study populations, anagrelide reduces the platelet count to below 600 times 10 to the 9th power/litre in two-thirds of patients. No data are available on the clinical implications of this reduction in platelets. (5) Between 10% and 20% of patients treated with anagrelide experience cardiovascular adverse effects (palpitations, myocardial infarction, heart failure) or neurological adverse effects (headache, stroke, transient ischaemic attack). Gastrointestinal disturbances are also frequent (diarrhoea, nausea, abdominal pain, pancreatitis). Some of these adverse effects can be fatal. (6) Follow-up is too short to show whether anagrelide affects the risk of progression to cancer. (7) In practice, anagrelide has a less favourable risk-benefit balance than hydroxycarbamide, which remains the first-line cytotoxic agent in this setting. Anagrelide therapy can be considered if hydroxycarbamide fails or is poorly tolerated, provided patients are included in a long-term clinical trial.

Heart disease is the number one killer in the USA. In Jordan, cardiovascular disease is the leading cause of death, and about 34.5% of women die of cardiovascular disease as compared with 44.25% of men. The differences between men and women in heart disease, such as signs and symptoms presentation, diagnostic and therapeutic interventions, are becoming more apparent in the literature. There is a dearth of research regarding gender differences among Jordanian myocardial infarction (MI) patients. Therefore, the purpose of this study was to explore the differences between Jordanian men and women in signs and symptoms presentation of MI and follow-up care. A convenience sample of 83 patients (26 women and 57 men) who were diagnosed with MI, mentally competent and haemodynamically stable were used to explore the research questions. An interview guide and chart audit were used to elicit information about initial and associated signs and symptoms and treatment plan of MI patients. Chest pain was the most common initial symptom in both men and women. The four most common associated signs and symptoms reported by both men and women were general weakness, sweating, nausea and fatigue. However, women experienced more general weakness and sweating compared with men. Women were less likely to receive intravenous nitroglycerin, heparin and thrombolytic therapy for the treatment of MI. Chest pain was the initial symptom of MI reported by men and women. Although similarities exist in the associated sings and symptoms, women might experience different associated signs and symptoms from men. Despite these similarities, women are still less likely than men to receive the therapeutic regimen used for men.
