Surgical gloves, condoms, and air balloons made of natural rubber or latex contain approximately 2% protein. With the use of instruments made of rubber, reddening, urticaria, itching, and, in extreme cases, anaphylactic reaction can occur. Milder symptoms disappear within 1/2-2 hours without intervention. In the past 5 years, 100 such cases have been reports, 50% from Finland and Sweden. During testing of hospital personnel, 15 out of 512 people developed urticaria caused by the latex content of surgical gloves. According to Finnish data, another 24% of those allergic to gloves got similar urticaria or itching from using condoms. There was a US report of a case of anaphylactic reaction caused by the condom. The sensitivity test can be based on the determination of immunoglobulin E (IgE) antibody or on the determination of histamine release. The reliability of the former is 60% and that of the latter 94%. The symptoms are treatable, but it is best to avoid contact with materials containing latex; in surgical practice it is advisable to use gloves made of artificial rubber, such as Elastyren or Dermaprene.

A 53-year old patient was admitted because of severe urticaria and itching aggravating since 9 months. Laboratory findings like increased sedimentation rate and leucocytosis were suspicious for an infection-associated allergy or a paraneoplastic syndrome. After exclusion of a gastro-intestinal tumor search for the source of a possible infection was intensified by several fecal analyses and trophozoites were found indicating an infestation of the small bowel by Giardia lamblia. Finally lamblia were detected in duodenal aspirate. After therapy with metronidazole 3 x 400 mg/die for 10 days all parameters of infection were normalized and the patient was permanently relieved from symptoms.

Fentanyl citrate is a synthetic narcotic 1,000 times as potent as meperidine. It produces minimal hemodynamic effects and is characterized by a rapid onset of sedation and analgesia, a relatively short duration of action (approximately 30 to 40 minutes), and rapid reversal with opiate antagonists. These properties make fentanyl an ideal drug for emergency department use. The safety of fentanyl use in an adult ED population has not previously been studied. We retrospectively reviewed the charts of 841 patients who received fentanyl at the University of Cincinnati Center for Emergency Care between January 1985 and June 1988. The study population included 497 (59%) men and 344 (41%) women, with an average age of 33 years. The average dose of fentanyl was 180 micrograms (range, 25 to 1,400 micrograms). Six patients (1%) experienced mild side effects including nausea (one), emesis (two), urticaria (one), and pruritus (two). Nine patients (1%) developed more serious complications including six cases (0.7%) of respiratory depression and three cases (0.4%) of hypotension. Two of 183 patients (1%) who received midazolam and two of nine patients (22%) who received haloperidol developed respiratory depression. Four of the six patients with respiratory depression and two of the three patients with hypotension were intoxicated. All of the complications were transient, and none resulted in hospitalization. We conclude that fentanyl is a safe drug for use in the ED. To maximize safety, we recommend careful dosing and titration, close patient monitoring, and the availability of naloxone hydrochloride and resuscitation equipment.(ABSTRACT TRUNCATED AT 250 WORDS)

A case of a severe anaphylactic reaction in a 30 year old man after 2 ml of 1% lidocaine injected subcutaneously is reported. It consisted in pruritus, urticaria, hypotension (Pasys: 50 mmHg), tachycardia (170 b.min-1) and a coma of short duration. The patient recovered after 1 mg adrenaline injected subcutaneously. The patient's history included a less severe but similar accident, but no manifestations of atopy. The total IgE, two months after the accident, were at the upper limit of normal. A human basophil degranulation test was positive for lidocaine and negative for other amide local anaesthetic agents and preservatives. Similarly, lidocaine was the only molecule giving a positive reaction with intradermal testing. Skin sensitivity to histamine was negative. Although for several authors true allergy to lidocaine is questionable, the case reported here can be added to the other 47 published since 1961.

The intensive morbidity index in respect of allergic dermatoses has made up 12.07 in 1986, allergic dermatitis being the most prevalent (72%). The morbidity has been the highest among subjects aged 21 to 40. Seasonal changes in the allergic dermatoses incidence rates have been determined: skin itching, urticaria, and neurodermatitis have been the most prevalent in October, whereas eczema occurred mostly in May.

To examine the occurrence of latex allergen in condoms and to study the symptoms caused by contact with condoms, 46 patients with latex-glove contact urticaria (LGCU) were investigated. 7 (24%) of the 29 patients with a history of condom use had experienced local swelling and/or pruritus during intercourse, confirming that condoms can cause local symptoms in latex allergic subjects. Prick tests performed on 16 different condom brands showed that 4 brands caused positive reactions in 52-67% of patients. The remaining 12 brands were not as allergenic and 1 brand was totally negative on prick testing. 1 highly allergenic condom brand was examined by high-pressure liquid chromatography (HPLC), which showed similar protein profiles to those detectable in latex gloves and natural rubber. These results show that, in addition to rubber gloves and balloons, condoms should also be considered as possible sources of latex, and that patients with LGCU should be advised to avoid condoms.

This article concerns itself with three common reactions (local, toxic and anaphylactic) resulting from insect or arthropod bites and stings. A local reaction consists of sharp, localized pain followed by a reddening at the site, which usually resolves itself in 24 hours. A toxic reaction may include gastrointestinal symptoms, fever, headache, dizziness or convulsions, often following an episode of multiple stings. An anaphylactic reaction may be mild (hives, itching) or severe (systemic reactions including airway and cardiovascular symptoms). Even though most bites and stings are not serious, nurse practitioners should be aware of potential death resulting from insect sting allergy. They should teach hypersensitive patients, or patients with a history of a systemic reaction to any agent, about prophylactic measures. Tables showing the characteristics of insects that cause cutaneous lesions in humans, and measures necessary to decrease the risk of being stung, can be used as learning tools to prevent insect sting allergy. Because of the rapid onset of anaphylaxis, life-saving measures include awareness in persons who are hypersensitive, emergency preparedness and preventing bites and stings from occurring.

The effects of brompheniramine maleate (12 mg twice daily in sustained release form) and terfenadine (60 mg twice daily) on the symptoms and well-being of 16 adults with urticaria with or without dermographism were assessed by symptom questionnaire. Following an initial 2-week period without therapy, each drug was taken for 2 weeks in a randomised double-blind cross-over study. Both drugs produced significant relief of itch and rash but only brompheniramine produced significant drowsiness. Brompheniramine maleate was more effective than terfenadine in the patients with dermographism.

The diagnosis of systemic mastocytosis without urticaria pigmentosa has been made with increasing frequency since modern methods of histamine assay have been used clinically. We examined the incidence of urticaria-angioedema and mastocytosis over a recent 12-month period. Of 490 new patients we saw, 52 had urticaria-angioedema, and ten had evidence of excess histamine +/- PGD2, with at least ten mast cells per high-power field on skin biopsy. The average age was approximately 35 years; the male:female ratio was 1:4 for urticaria-angioedema and 1:2 for mastocytosis. Symptoms of mastocytosis included flushing, abdominal cramping/diarrhea, syncope, urticaria-angioedema, pruritus, and headache. Symptoms have typically been prevented by a combination of H1 and H2 antagonists, with addition of a cyclo-oxygenase inhibitor in syncopal cases. Acute hypotension has responded to epinephrine.

From clinical-pharmacologic and clinical data involving over 2,800 patients, astemizole appears to be a very effective and well-tolerated antihistamine. It is superior to placebo and commonly used antihistamines for the relief of rhinitis, particularly rhinorrhea and sneezing. It has a pronounced effect on ocular itching and lacrimation in conjunctivitis and on pruritus and wheals in urticaria. This superiority is due to a very specific, almost complete and sustained histamine H1-blockade. The clinical data confirm the experimental data in relation to its lack of sedative effects.
