Miconazole, a new imidazole antimycotic agent, was given intravenously to five children with chronic mucocutaneous candidiasis over an 18-month period. There was marked improvement of mucosa and skin in two patients, moderate-to-milk improvement in two, and no improvement in one. Nail lesions were not improved in any patient. Adverse reactions included phlebitis, pruritus, nausea and dizziness, rash, wheezing, mild transient anemia, and mild transient transaminase (SGOT and SGPT) elevations; it was necessary to discontinue treatment in only one patient. No renal toxocity was noted. Miconazole appears to be a relatively safe and promising alternative to amphotericin B in chronic mucocutaneous candidiasis.

A clinical study was performed on 41 asthmatic patients. After complete physical and spirometric examinations, they received capsules containing 200 mg anhydrous theophylline per capsule t.i.d. for three weeks. All other antiasthmatic medications were omitted during this study. The results showed that these capsules (Elixophyllin Capsules) produced statistically significant improvement in wheezing, dyspnea, global clinical assessment, vital capacity, and forced expiratory volume at 1 second. Side effects, which were generally mild and transient, were those usually reported for theophylline and were observed in 11 of the 41 patients. One patient dropped out of the study because of extreme nausea. It was concluded that theophylline as a single entity can provide significant improvement in asthmatic patients at a total daily dose of 600 mg.

A case report of an urban family who experienced excessive exposure to organophosphate and carbamate pesticides is presented. All three family members developed symptoms that were compatible with cholinesterase inhibition: headache, lightheadedness, wheezing, shortness of breath, nausea, and fatigue. Serial measurement of red blood cell and serum cholinesterases soon after exposure and during subsequent months confirmed the diagnosis of pesticide poisoning. This report demonstrates that the misapplication of pesticides commonly used in residences in urban areas can cause acute pesticide poisoning and demonstrates the usefulness of repeated measurements of cholinesterase during the post-exposure period in establishing the correct diagnosis.

A clinical study was carried out in 20 patients in coronary angiography to compare two low-osmolar contrast media, sodium-meglumine ioxaglate and iopromide. Ten patients presented a stage III coronary disease and the other ten had a stage IV coronary disease. In the latter group, 70% of the patients received sodium-meglumine ioxaglate and 30% were given iopromide. None of the patients given iopromide had a previous history of allergic-like reactions to contrast media as opposed to the sodium-meglumine ioxaglate group where two patients had a previous hypersensitivity reaction to contrast agents. In spite of these adverse conditions in the sodium-meglumine ioxaglate group, no significant difference was found between both preparations as to overall tolerability. The following side effects were observed: slight nausea and wheezing in a patient given sodium-meglumine ioxaglate; medium intense nausea, vomiting and headache in a patient administered iopromide; one case of angina pectoris occurring 8 minutes post-injection of iopromide. Similarly, no significant difference in overall cardiac tolerability could be found between the two contrast media, although sodium-meglumine ioxaglate would tend to be better tolerated in terms of heart rate and contractility. Radiographic efficacy was considered to be equivalent for both contrast agents though the test solutions had different iodine concentrations. In summary, the two low osmolar contrast media proved well tolerated and showed satisfactory diagnostic efficacy in this population at high cardiovascular risk.

Contrast media reactions may be classified as anaphylactoid, vasomotor, severe or life threatening, and fatal. Anaphylactoid reactions mimic immunoglobulin E-mediated hypersensitivity in that signs may consist of urticaria, angioedema, wheezing, dyspnea, hypotension, or shock. These reactions occur in 2% to 8% of all contrast media infusions. Vasomotor reactions occur in 5% to 8% of patients and consist of nausea, vomiting, flushing, and warmth. Severe reactions during which there is a concern for life occur about once per 1000 procedures. Fatalities have occurred in from 1:3000 procedures for intravenous cholangiography to between 1:10,000 to 1:100,000 procedures for intravenous urography. The pathogenesis of contrast media reactions is unknown, and various mechanisms may be associated with different clinical features. Radiocontrast media infusions can cause rises in plasma histamine and complement activation by either classic or alternate pathways or nonsequentially, yet adverse reactions may or may not occur. Abnormalities in the complement system or an increased conversion of prekallikrein to kallikrein has been demonstrated in some patients who have had anaphylactoid reactions. It is unknown if these mechanisms can explain the pathogenesis of anaphylactoid contrast media reactions. When patients who have had definite anaphylactoid reactions require a repeat procedure, the incidence of reactions ranges from 35% to 60% for intravascular infusion. Pretreatment with prednisone and diphenhydramine has been demonstrated to reduce this reaction rate to 9% in 465 procedures. Prednisone-diphenhydramine and ephedrine have further reduced the reaction rate to 3.1% in 192 procedures. These results are statistically significant (X2 = 5.4996, p = 0.019). Emergency equipment should be available should a severe reaction occur.(ABSTRACT TRUNCATED AT 250 WORDS)

An outbreak of metal fume fever (MFF) among workers involved in cutting brass pipes with electric cutting torches in an enclosed, poorly ventilated steam condenser is described. Twenty-six workers were affected. Symptoms most commonly reported were fever (21), dyspnea (23), chills (21), headache (21), and nausea (19). Fourteen of the workers experienced the symptom of an unusual sweet or metallic taste in the mouth. Clinical signs were limited to wheezing or rales in eight patients. Leukocytosis and an increase in band cell forms were noted in 21 and 20 of 24 workers, respectively. The median time interval between exposure and onset of symptoms was five hours. None of three workers who spent less than one hour in the condenser became ill, whereas 25 of 26 of those who spent more than one hour became ill (p = .001). Five of 12 workers had urine copper levels in excess of 0.05 mg/l. To our knowledge, this is the first reported outbreak of MFF for which urinary copper levels have been measured.

The efficacy of metaproterenol (orciprenaline) and theophylline given orally at currently recommended doses was examined in 34 children with chronic asthma using a randomized double-blind cross-over evaluation of four weeks' duration for each active regimen. No serious adverse effects were seen with either medication, but tremor occurred more frequently with metaproterenol (P less than 0.01). No significant differences were observed in the frequency of nausea, vomiting, headache, or insomnia (P greater than 0.05). Symptoms of wheezing, coughing, exercise intolerance, and interference with sleep were more frequently associated with the oral metaproterenol regimen; completely asymptomatic days occurred 50% more frequently in association with theophylline therapy (P less than 0.01). Mean peak flows, performed twice daily during each of the four-week study periods, were 86 and 92% of predicted for metaproterenol and theophylline, respectively (P less than 0.05). Pulmonary function decreased significantly less with theophylline than with metaproterenol among those who completed six minutes of treadmill exercise during both regimens (P less than 0.05). Corticosteroids, used for acute symptoms that failed to respond to the addition of inhaled metaproterenol, were required in four patients during both regimens, in ten patients only during the metaproterenol regimen, and in one patient only during the theophylline regimen (P less than 0.02). Thus, theophylline therapy was associated with fewer adverse effects, fewer symptoms of asthma, better pulmonary function, better exercise tolerance, and less requirements for corticosteroids than was treatment with metaproterenol.

The range of diseases in which intravenous immunoglobulin (IVIG) is effective has expanded significantly since its initial use in primary antibody deficiency. There are at present at least 17 preparations of IVIG in use worldwide with similar profiles of adverse effects. Infusion-related effects range in severity. Mild adverse reactions (headache, flushing, low backache, nausea, wheezing) are often associated with a fast infusion rate, and respond rapidly on slowing the infusion. Very rare episodes of life-threatening anaphylaxis may occur, particularly in those IgA-deficient patients with anti-IgA antibodies; such patients should receive an IgA-depleted preparation of IVIG. There are concerns with any blood product about safety in regard to viral transmission. The 4 outbreaks of non-A non-B hepatitis (probably hepatitis C) in the 1980s were associated with the use of particular batches of IVIG. The more recent exclusion of all anti-hepatitis C virus positive individuals from the donor pool, and the introduction of specific antiviral steps in the manufacture of IVIGs, should prevent further outbreaks. The human immunodeficiency virus (HIV) is effectively inactivated during the manufacturing process itself and HIV transmission has not been reported with IVIG. Rarely, haematological (Coombs' test positive haemolysis), neurological (aseptic meningitis) or renal (transient rises in serum creatinine) adverse effects may be seen when high doses of IVIG are used for immunomodulatory purposes. Haemolysis, due to passive transmission of blood group antibodies (anti-A, anti-D), may be prevented by selecting IVIG batches that give a negative cross-match between the recipient's red cells and IVIG.(ABSTRACT TRUNCATED AT 250 WORDS)

A mixture of paraquat and water was applied, by helicopter, to agricultural fields near a residential community and near an associated commercial complex. Drift from the application passed directly over the community, which resulted in resident complaints to the local county agricultural department. A community survey was undertaken to determine what health consequences, if any, resulted from the drift. A comparison of 2-wk self-reported symptom rates between the exposed community and three historical control communities indicated that 10 symptoms were elevated significantly at p < .05: cough, diarrhea, eye irritation, headache, nausea, rhinitis, throat irritation, trouble breathing, unusual tiredness, and wheezing. An internal comparison, which predicted symptom rates by an index of paraquat exposure (smelling an unusual odor in the prior 2-wk period), indicated fever (relative risk [RR] = 11.97) and nausea (RR = 3.75) to have elevated relative risks. Odor perception also predicted the report of a greater than the average number of symptoms. Based upon these findings, it was concluded that these residents probably did experience an increase in health symptoms from the drift. It is recommended that paraquat not be sprayed near residential communities.

Adverse reactions to radiopharmaceuticals are comparatively few in number. Various estimates quote an incident rate of 1 to 6 reactions per 100,000 injections. Other figures quoted are 1 in 800 for the bone-seeking radiopharmaceutical methylene diphosphonate, and 1 in 400 for the lung visualisation agent macroaggregated albumin. The very low numbers of reported adverse effects probably reflect the tiny amounts of material which are used in the formulation of radiopharmaceuticals. Adverse reactions to radiopharmaceuticals are usually mild and transient and require little or no medical treatment. A few reactions involve respiratory or circulatory collapse or loss of consciousness. Several fatalities have been reported with the liver scanning agent 99mTc (technetium 99m)-albumin colloid. Clinical manifestations may be categorised under the headings of vasomotor effects i.e. faintness, pallor, diaphoresis or hypotension, and anaphylactoid effects such as nausea, dermographism, wheezing, bronchospasm, erythema and pruritus. The most prominent group of radiopharmaceuticals that have been reported to produce adverse events are the diphosphonates, which are used for scanning the skeleton. Typical diphosphonate reactions include erythema (especially over the extremities), nausea, vomiting and malaise. The onset of reaction is usually 2 to 3 hours after injection. The second group of radiopharmaceuticals which give rise to adverse events are the colloids, which are used for liver and spleen scintigraphy. Typical colloid reactions include pallor, nausea, flush and pulse changes. Adverse events may also occur as a result of the patient's medication interfering with the disposition of the radiopharmaceutical. Although not usually hazardous or dangerous, such events may be so pronounced that a marked deviation in the expected pharmacokinetics may occur. Drug interactions can be conveniently categorised under the headings of unusual handling of the radiopharmaceutical because of pharmacological action, genuine in vivo interaction between the medication and radiopharmaceutical, drug-induced disease and interaction between the radiopharmaceutical and catheters or syringes. The most serious drug interactions are those where the patient is taking cortisone or cytotoxic agents prior to tumour scintigraphy. Other important effects occur in patients undergoing bone scanning who are receiving iron preparations. Nifedipine has been reported to produce quite severe problems in scanning, including difficulties in the radiolabelling of red cells (for cardiac scintigraphy), and other effects where the drug appears to prevent the transport of bone-seeking materials into the skeleton. Many drugs alter hormonal status and these effects may produce marked deviations from the expected biodistribution. Diethylstilbestrol (stilboestrol), digitalis, gonadotrophins, phenothiazines and cimetidine all increase estrogen levels in high doses.(ABSTRACT TRUNCATED AT 400 WORDS)
