Intravenous fluorescein angiography is a commonly performed and extraordinarily valuable diagnostic procedure. The frequency of adverse reactions after angiography has varied considerably in previous reports. In a prospective study of 2789 angiographic procedures in 2025 patients, the authors found that the percentage of adverse reactions depended strongly on the patient's angiographic history. Overall, adverse reactions followed 4.8% of the angiographic procedures. These reactions included nausea (2.9%), vomiting (1.2%), flushing/itching/hives (0.5%), and other reactions (dyspnea, syncope, excessive sneezing) (0.2%). No cases of anaphylaxis, myocardial infarction, pulmonary edema, or seizures occurred. The percentage of reactions was 1.8% for patients who had had previous angiography without ever having had an adverse reaction. In contrast, the percentage of reactions was 48.6% for patients who had had an adverse reaction to angiography previously.

We report a case of nearly fatal cardiovascular collapse attributable to an idiopathic anaphylactic reaction in a 76-year-old man. The event began with gastrointestinal symptoms of abdominal cramps, diarrhea, nausea, and vomiting as manifestations of IA. The patient subsequently progressed to develop urticaria, flushing, cardiovascular symptoms of chest pain, hypotension, and eventually cardiovascular collapse and myocardial infarction over a five-hour interval. This case emphasizes that the potential for life-threatening cardiovascular events from IA exists in patients without previously defined cardiac risk factors.

A defined general population of 159,200 male and female native Swedes born in the period of 1911-1940, from an urban catchment area of the then only general hospital, was followed over a decade (1970-1979) with regard to inpatient hospitalization for all kinds of diagnoses. Psoriasis cases (n = 372) are significantly (p less than 0.001) associated with a spectrum of diseases: male as well as female psoriatics seem to show excess rates of viral infections, alcoholism, hypertension, pneumonia, liver cirrhosis, urticaria, and rheumatoid arthritis. Psoriasis in males only seem to be associated with iritis and ankylosing spondylitis, whereas psoriasis in females only is associated with lung cancer, diabetes, obesity, myocardial infarction and asthma.

Three cases of apparent anaphylactoid reactions to zomepirac sodium (Zomax) are reported. One patient initially appeared to have a dissecting abdominal aortic aneurysm with vascular collapse. The second patient experienced conjunctival pruritus after each of several doses of zomepirac before emergency department presentation with acute dyspnea and urticaria. The third patient had been admitted previously with a diagnosis of rule out myocardial infarction, which in retrospect was probably a zomepirac reaction. All three recovered uneventfully.

Aspirin is one of the world's most commonly used medications and its use benefits many diverse conditions. Adverse reactions, however, are relatively common as well. Hypersensitivity to aspirin can be manifested as acute asthma, urticaria and/or angioedema, or a systemic anaphylactoid reaction. We report 3 cases in whom aspirin was indicated for secondary prophylaxis of myocardial infarction but in whom a remote history of an untoward reaction to it prevented its initial use. These patients all underwent further evaluation of their pulmonary and allergic history and all 3 were challenged with aspirin. Two patients were found not to be sensitive and started on aspirin, the other had a classic asthmatic reaction to the drug and was successfully desensitized to aspirin allowing for its use.

Myocardial infarction (MI) occurring during the course of an allergic urticarial reaction in the absence of systemic hypotension has been rarely reported. This paper reports the case of a 28-year-old woman with no significant risk factors for coronary artery disease who presented with generalized urticaria associated with chest pain and had electrocardiographic and enzymatic evidence of an acute MI. Review of the literature suggests that local histamine release may induce spasm of the coronary vasculature, thus leading to myocardial ischemia and infarction.

Recent studies have shown that chronic odontogenic infections could pose a risk for myocardial infarction, cerebral ischemia, and arteriosclerosis. However, the correlation between urticaria and dental infections has rarely been examined so far. Therefore, we performed a case-control study using a standardized questionnaire and examination. We investigated 66 patients suffering from an acute or chronic urticaria and 65 age- and sex-matched healthy patients as a control group. Dental status was determined by a so-called total dental index (TDI) which primarily reflects caries, periodontitis, periapical lesions, and nonvital and missing teeth. All 66 patients were referred from the department of dermatology. After their treatment in hospital, all patients received a questionnaire with questions on intensity and localization of the urticaria. The TDI of the urticaria patients was slightly better ( n=66; 2.6+/-1.98) than that of the control group ( n=65, TDI=3.3+/-1.86). Subsequently, it was determined if the urticaria had receded after dental treatment. In conclusion, chronic dental infections do not seem to correlate with an increased risk for urticaria.

We report the case of an atopic male, 76 years old, with post-myocardial infarction ischaemic cardiopathy, arterial hypertension and a history of insect-sting induced large local reactions who died because of a biphasic anaphylaxis subsequent to multiple Vespid stings (about 15). Within approximately ten minutes after the stings he developed urticaria, extended erythema and hypotension (90/60 mmHg), measured by a family member. The objective physical examination by the emergency doctor at the patient's home revealed an orticarioid reaction and erythema of the back and neck, an unaffected respiratory apparatus and CNS, normal pupils, a pulse rate of 74, normal blood pressure ranging from 120/70 to 130/60 mmHg. The patient was administered antihistamine and corticosteroid through parenteral route. During the 45' observation period at the patient's home the urticaria subsided but not to completion. Approximately 40 minutes after the emergency doctor left, the urticaria reoccurred, angioedema of the neck and worsening asthenia developed. The patient died, despite attempts to resuscitate him by the emergency doctor that had been called out again. A post-mortem examination revealed generalised eodema of the lungs, brain, glottis, and bowels due to the severe characteristic systemic compromise of anaphylaxis. The Authors discuss whether an early use of adrenalin and/or a longer observation time could have saved the patient.

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.

A 43-year-old man with no cardiac history presented with chest pain followed by cardiac arrest. He was successfully defibrillated and underwent primary percutaneous coronary angioplasty to a culprit coronary artery lesion. He later re-presented with a diffuse urticarial rash and lip swelling, reporting that these symptoms had been present for 4 weeks before his cardiac arrest and voicing concern that a further cardiac arrest may be imminent. A diagnosis of post-viral or idiopathic autoimmune urticaria and angioedema was made. Given the absence of cardiac symptoms before the development of the rash, it was hypothesised that coronary artery spasm precipitated by histamine release due to his dermatological condition contributed to his myocardial infarction and cardiac arrest. The final diagnosis was therefore cardiac arrest secondary to type II Kounis syndrome, resulting from idiopathic autoimmune or post-viral urticaria and angioedema.
