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.

Between 1979 and 1989 17 patients aged two months to 12 years with acute myocardial infarction of any cause (other than after cardiac surgery) were seen at a children's hospital. Eight died from three days to three years after diagnosis (overall mortality 47%). The nine survivors, now aged 2-17 years, have been followed for one to 10 years (mean follow up five years) after infarction. The commonest causes of myocardial infarction in this series were anomalous origin of left coronary artery from the pulmonary artery (six patients (35%] and Kawasaki disease (five patients (27%]. The main symptoms of acute myocardial infarction were dyspnoea, vomiting, and difficulty feeding. Diagnosis was made in all patients by electrocardiography and confirmed by echocardiography, cardiac catheterisation, or at operation. All survivors were symptom free with excellent exercise capacity. The left ventricular ejection fraction in survivors ranged from 21% to 66%, and only one child was on regular cardiac medications. There were no cases of late sudden death. Twenty four hour Holter monitoring performed on survivors was normal (seven) or showed minor abnormalities only (one), suggesting that serious arrhythmia is rare after paediatric myocardial infarction. Myocardial infarction in children had a high early mortality; however, the incidence of serious arrhythmia was low in the survivors, who had a good exercise tolerance even when the left ventricular ejection fraction was low.

We tested the hypothesis that the administration of nitrous oxide (N2O) causes major (e.g., myocardial infarction, neuronal injury, hypoxemia, infection, death) or minor (e.g., nausea, vomiting, headache, earache) untoward effects in patients requiring anesthesia for 1.5-4 h. Given the higher morbidity and mortality associated with aging, we also tested whether aging increased any untoward effect of N2O. Finally, we investigated whether the substitution of N2O for a fraction of the anesthesia supplied by isoflurane altered the latter's pharmacologic effects. We studied 270 patients scheduled for elective total hip arthroplasty (n = 100), carotid endarterectomy (n = 70), or transsphenoidal hypophysectomy (n = 100) who were randomly assigned within each surgical group to receive isoflurane with or without 60% N2O. Regardless of patient age, we found no difference in major or minor untoward outcomes between anesthetic groups, nor a trend to suggest that a larger data cohort would reveal a significant adverse effect of N2O. The addition of N2O administration decreased the isoflurane requirement for clinical anesthesia but did not alter most of the clinical variables measured in practice, including blood pressure, heart rate, rate of recovery from anesthesia, development of postoperative pain, patient satisfaction with anesthesia, or duration of anesthesia or of hospitalization. Patients given N2O were no more likely to dream during anesthesia, remember events during anesthesia, or be frightened by those events. Our results support the continued use of N2O to anesthetize patients for elective surgery.

Clinical trials in Europe have found that a single oral dose of RU-486, followed by prostaglandin administration, effectively and safely terminates early pregnancy in about 95% of women. In a multicenter study carried out in France, 1 600-mg dose of RU-486, followed 36-48 hours later by intramuscular sulprostone or intravaginal gemeprost, induced complete abortion in 96% of 2000 women with up to 49 days of amenorrhea. In a British multicenter study, the combination of RU-486 and intravaginal gemeprost induced abortion in 95% of 600 women with up to 63 days of amenorrhea. RU-486 is not effective in aborting ectopic pregnancies. Bleeding usually starts 1-2 days after treatment and lasts for 1-2 weeks. About 1% of patients have required curettage since the amount of blood loss exceeds that in a normal menstrual period. The other side effects recorded with any frequency--abdominal cramping, nausea, vomiting, diarrhea, and headache--are all transitory and mild. Only 1 case of myocardial infarction has been reported in the more than 20,000 RU-486 acceptors studied. Endometritis and salpingitis are extremely rare complications. There have been no maternal deaths, and no fetal abnormalities have been observed in women who took RU-486 alone early in pregnancy and failed to abort.

A phase II trial of intermittent high-dose recombinant interleukin-2 (rIL-2) was initiated to evaluate the response rate, remission duration, and toxic effects in patients with measurable metastatic renal cell carcinoma. The rIL-2 was administered as a bolus intravenous infusion at a dose level of 10.0 x 10(6) U/m2 three times weekly, preceded by indomethacin (50 mg orally). Dose reductions of rIL-2 for hypotension and other grade 3 or 4 toxic effects were permitted. Forty-four patients were entered and 41 were eligible. Previous treatment included nephrectomy (23 patients), radiation therapy (seven), and hormone therapy (three). Most toxic effects observed were moderate and included nausea, vomiting, anorexia (85%); hypotension (85%); fever, chills (78%); central nervous system changes (24%); myelosuppression (27%); and creatinine elevation (15%). Four instances of grade 4 toxicity were observed and included nausea, vomiting with dehydration; hypotension; and myocardial infarction. Thirty patients (73%) required dose adjustments because of toxicity. Five responses (12%) were seen, which included one complete and four partial. Sites of response included lung, liver, and soft tissue; the duration of response ranged from 2 to 20+ months. These results demonstrate that this schedule of rIL-2 can be administered in an outpatient setting, and can produce tumor regression in patients with metastatic renal cell carcinoma, including durable complete responses.

A case of spontaneous oesophageal rupture or Boerhaave syndrome is described. The absence of the typical initial vomiting together with a clinical picture that successively indicated repeated myocardial infarction, pancreatitis and pulmonary abscess delayed diagnosis by 4 days, after which emergency thoracotomy, performed on the identification of extravisceral overflow by contrast radiography using a water-soluble medium, revealed necrotic inflammation of the oesophagus, mediastinum and left lung that was so severe that only thoracic drainage was possible. After an initial improvement the patient died of septic shock on the 16th postoperative day.

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.

We conducted a study to determine the type, incidence, and timing of complications that occur in patients who have a carbon monoxide (CO) exposure serious enough to require hyperbaric oxygen therapy (HBOT). Complication data were retrospectively collected from a ten-year period for 297 consecutive CO-poisoned emergency department patients who received HBOT. HBOT was indicated for 41% of the patients because of an elevated carboxyhemoglobin (COHb) level alone. Central nervous system dysfunction, including loss of consciousness, and/or cardiovascular dysfunction, was the criteria for HBOT in 59% of patients, regardless of their COHb level. The mean peak COHb level was 38 mg%, with 88% of patients having a peak COHb level greater than 25 mg%. The mortality rate was 6% in this case series. Cardiac arrest occurred in 8% of patients; all experienced their first arrest prior to HBOT. The 3% of patients who sustained an isolated respiratory arrest and those who had a myocardial infarction did so prior to HBOT. Several complications, however, occurred for the first time or as a recurrent event during HBOT. These included emesis (6%), seizures (5%), agitation requiring restraints or sedation (2%), cardiac dysrhythmias or arrests (2%), and arterial hypotension (2%). No patient's level of consciousness deteriorated subsequent to the initial resuscitation except for those who later had a generalized seizure. The most significant complication attributable to HBOT was tension pneumothorax, noted in three patients (1%).(ABSTRACT TRUNCATED AT 250 WORDS)

Adverse reactions to ophthalmic patients during 9909 fluorescein angiographies during 9 years were registered. Nausea (4.6%) and vomiting (1.3%) were the most common untoward reactions. Allergic skin manifestations occurred in 48 patients, and 5 patients complained of shortness of breath. 56 patients (0.6%) felt dizzy during or immediately after the investigation. Nine patients complained of chest pain, three of whom developed myocardial infarction. Sixteen patients collapsed during the procedure. One healthy male, 42-year-old, collapsed after the injection of fluorescein during angiography, and electrocardiogram showed an asystole of 24 seconds. Otherwise, the electrocardiograms registered on 100 consecutive patients did not reveal any systematic changes in heart rate or rhythm during fluorescein angiography.

The authors present a retrospective study of 46 consecutive patients aged from 70 to 79 years (mean 73.3 +/- 2.5 years) with suspected coronary artery disease who, being unfit for exercise tests, were explored by myocardial scintigraphy with thallium 201 after coronary dilatation with intravenous dipyridamole. The examination was well tolerated by 30 patients. Such classical side-effects as chest pain, malaise, dizziness, headache, flushing, vomiting and transient arrhythmia or repolarization disorders were recorded, but they were not more frequent than in younger subjects. However, the occurrence of severe hypotensive malaise relieved by theophylline in two cases and of angina in about one third of patients with myocardial ischaemia means that the procedure must be performed under close supervision. A fall in blood pressure (-11 mmHg on average) and a rise in heart rate (+8 beats/min on average) were usual. Post-scintigraphy follow-up of patients over a mean period of 11.1 +/- 6.2 months showed that a reversible defect of thallium 201 uptake, due to redistribution, is a highly selective indicator of patients who are particularly exposed to a cardiac accident in the short--or mid-term. Only one out of 26 patients without reversible ischaemia (4 p. 100) subsequently presented with a major coronary event (unstable angina). In contrast, in the group of 20 patients with reversible ischaemia three required early myocardial revascularization; furthermore, five serious accidents (29 p. 100) occurred among the 17 patients who were left under medical treatment, including two sudden deaths, two cases of unstable angina and one case of myocardial infarction.(ABSTRACT TRUNCATED AT 250 WORDS)
