The paper comprises 63 patients with diagnosed vasculitis of the skin who had abnormal findings in the urine. Thirteen of these patients had positive skin findings and abnormal findings in the urine, with concomitant attacks of dyspnea as seen in bronchial asthma. These patients account for 20% of the entire group, while there was an incidence of 37% of systemic manifestations. Skin findings: 45% had a maculopapular rash, 36% had urticarial findings, 13% had urticaria and angioedema and 6% had angioedema alone. Nonspecific biologic syndrome of evolution was statistically significant while no significant changes were found in the number of white blood cells and eosinophils. The degree of proteinuria ranged from 0.1 g/L to 1.16 g/L. Most patients with proteinuria above 0.25 g/L had microhematuria. Slightly over 50% of the patients had signs of complement activation by the alternative pathway, along with the presence of cryoglobulins. Increased histamine in the serum was found in over 50% of the patients although the values of histamine did not correlate with the degree of proteinuria. Proteinuria was not detected in patients with very high values of histamine (and without signs of vasculitis), which indicates that histamine itself responsible for changes in the glomeruli. There is a possibility that local tissue hyperhistaminemia is responsible for the increased permeability of the basal membrane of the glomeruli. According to the obtained results, the etiology of proteinuria and microhematuria should be pursued in the pathogenesis of vasculitis as signs of complement activation indicate. Other possible causes for proteinuria were excluded. The proteinuria was selective, benign according to its course and degree, occurred concomitantly with skin findings and was absent during remission of the disease.

Taxol is an antitumor agent in clinical trial that has been shown to have activity against advanced ovarian carcinoma and melanoma. Hypersensitivity reactions (HSRs) have been one of the toxicities observed with administration of this drug. Of 301 patients treated, 32 patients have had definite (27 patients) or possible (five patients) hypersensitivity reactions to taxol. All but one patient had the reaction from the first or second exposure to this agent. Reactions occurred at a variety of doses and were characterized most frequently by dyspnea, hypotension, bronchospasm, urticaria, and erythematous rashes. Thirteen (41%) patients had received premedication designed to prevent such toxicity; nevertheless, they sustained HSRs. Prolonging the drug infusion appears to have somewhat reduced, but not obviated, the risk of HSRs. The cause (taxol itself or its excipient Cremophor EL; Badische Anilin und Soda-Fabrik AG [BASF], Ludwigshafen, Federal Republic of Germany) and the mechanism of these reactions to taxol are unknown. We provide guidelines to prevent or minimize such toxicity and treat reactions if they still occur.

We report on two cases of adverse reactions to topical treatment with monoethyl fumarate. One patient suffering from atopic dermatitis reacted with contact dermatitis; the other, suffering from psoriasis, developed a generalized, partly pustulous exanthema as well as signs of systemic involvement, such as tachycardia and dyspnea. As the causative mechanism we suggest non-immunological contact urticaria syndrome.

The efficacy and safety of almitrine bismesylate, a new respiratory stimulant, in patients with the hypoxaemic form of chronic respiratory insufficiency caused by chronic bronchitis and emphysema has been assessed. The multicentre trial of 12 weeks duration was double-blind and placebo controlled, with individual and group comparisons. Twenty three patients received almitrine 50 mg b.d. p.o. and 17 took placebo. In the almitrine group a significant increase in PaO2 was achieved (control value 54.4 mm Hg, rising to 59.1 mm Hg after 6 weeks, and to 59.4 mm Hg after 12 weeks). There was also a significant decrease in PaCO2 in the almitrine group after 12 weeks. No correlation was found between the plasma almitrine concentration, PaO2 and PaCO2. Lung function (FVC, FEV1, FEV1/FVC, Raw, TLC, RV, FRC) did not change in either group, but the degree of dyspnoea and performance in the 6 min walking test were significantly improved in the almitrine group. Adverse reactions appeared in 6 out of 23 patients on almitrine bismesylate (headache, urticaria, breathlessness, diarrhoea, chest pain, nausea and vomiting), causing drop out of 4 patients. Thus, almitrine bismesylate can be considered useful in the treatment of patients with chronic respiratory insufficiency.

Over an eight and a half year period 742 patients were assessed for allergy to stinging and biting insects in Queensland; 452 (61%) had allergic reactions to honey bees, 244 (33%) to wasps, 30 (4%) to various ants, 11 (1.5%) to march flies (Tabanus sp.) and five to tick infestation. One hundred and fifty one patients (20%) presented with large local swelling only (RXN1), 98 (13%) with urticaria and/or facial angioedema distant from the sting site (RXN2) and 492 (66%) with subjective or objective evidence of dyspnoea or hypotension (RXN3). Allergy testing was performed with honey bee and wasp venoms by skin testing or by Radioallergosorbent testing. Fifty nine patients (30%) with RXN3 responses to wasps failed to react to either test, while this applied to only 19 (6%) of the patients with RXN3 responses to bee stings. Thus, a large number of wasp-allergic patients with RXN3 responses could not be offered immunotherapy. A similar problem exists in the lack of availability of specific reagents for anti- and tick-induced dyspnoea or hypotension. A whole-body insect extract of march fly, however, appears useful.

A 24-year-old white woman reported sexual intercourse-related pruritus, hives, wheezing, and dyspnea within 5 minutes after ejaculation. Systemic reactions (SRs) were prevented by use of condoms. Prick testing confirmed sensitization to five Sephadex G-100-separated fractions of her husband's seminal plasma. The intradermal end point threshold concentrations (ETC) were 10(-4) and 10(-1) micrograms of protein per milliliter to fractions 2 and 3, respectively. Leukocyte histamine release studies exhibited 100% release to fraction 2 and 37% release to fraction 3. A 2-day protocol of rapid immunotherapy (IT) was performed with subcutaneous incremental doses of human seminal plasma (HuSePl) fractions 2 and 3. The patient experienced an SR after receiving a cumulative dose of 38.55 micrograms of fraction 2 on day 1. On day 2, rapid IT with fraction 2 was administered until the patient experienced a mild SR after having received a cumulative dose of 102.8 micrograms. There was a one-log10 increase in the intradermal ETC to both fractions 2 and 3 at the end of day 2. IT was continued three times weekly for 4 months until the patient tolerated 100 micrograms doses of both fractions 2 and 3. At 4 months, coitus was resumed without SRs, and HuSePl IT was stopped. The intradermal ETC to fractions 1, 3, 4, and 5 was increased 6 months after cessation of HuSePl injections, but there was a one-log decrease in the ETC to fraction 2. Our experience demonstrated that systemic tolerance can be achieved by parenteral administration of selected HuSePl fractions. Partial immunologic desensitization of patients with anaphylactic sensitivity can be achieved.(ABSTRACT TRUNCATED AT 250 WORDS)

A 17 years old girl experienced an anaphylactic reaction of urticaria, dyspnea, syncope and hypotension while riding a bicycle 55 minutes after eating shellfish Lapas shellfish which was a-like Sulculus Supertexta (SS). She recovered within several hours after the emergency treatment. Another attack occurred 3 months later while she was running with a dog 30 minutes after eating shellfish (Turbo Cornutus; TC). RAST scores were 4 for Lapas and 2 for TC. RAST inhibition test by ELISA showed a high crose-reaction between keyhole limpet hemocyanin (KLH) and Lapas, and between KLH and TC, while the cross reaction between Lapas and TC was low. Gel chromatography with sephacryl G-200 revealed that both Lapas and TC had several allergens with different molecules which were detected by ELISA. Exercise challenge produced an immediate fall of FEV1 and a significant increase in plasma histamine levels for 45 minutes.

A 15-year-old man with food-dependent exercise-induced anaphylaxis is reported. The patient had begun to run 4 hours after he had lunch on fried shrimps. When running about 2000 m, he suffered from general cutaneous erythema with itching, urticaria, angioedema of face and dyspnea. He had experienced the similar episodes associated with postprandial exercise before. Skin test and IgE-RAST were positive for shrimp. Exercise challenge test after having 20 g boiled shrimp was conducted, and the elevation of plasma histamine level was recognised. 25 cases with food-dependent exercised-induced anaphylaxis have reported in Japan. 13 of 25 cases were related with wheat, and 10 cases were related with shrimp. 14 of 25 cases had experienced the similar episodes. Exercise as part of planned health program has virtually mushroom world-wide. Therefore, the fact that anaphylaxis can be a complication of such exercise must be recognised if appropriate prevention and treatment are to be administered.

Allergic reactions during lymphography are uncommon, usually minor and difficult to attribute to a single agent because of the common practice of mixing patent blue dye and local anaesthetic before injection. A case is presented where injection of patent blue dye alone was followed by generalised urticaria, swelling and constriction in the throat and difficulty breathing.

Exercise and physical fitness are becoming increasingly popular in our society. As a result there are more individuals who are at risk for the development of acute respiratory emergencies associated with sports and athletics. EIB is a common feature of asthma and is characterized by a postexercise fall in FEV1 of more than 10 per cent. Although a variety of medications have been used for the prevention of EIB, cromolyn sodium and inhaled adrenergic agonists have been shown to be the most effective. EIA and cholinergic urticaria are two physical allergies in which hypotension can be brought on by exercise. In some individuals, EIA develops only in association with the ingestion of a particular food. Associated with sports and recreational activities in alpine areas is the risk of developing acute high-altitude medical problems. One of the most dramatic and potentially life threatening is high-altitude pulmonary edema. The management of this condition can be problematic, particularly if rapid descent to lower elevations is not possible. Although rare, spontaneous pneumothorax and pulmonary emboli do develop in the otherwise well-conditioned athlete. These entities must be considered when the physician evaluates any athlete in whom acute cough and dyspnea develop.
