We report 8 infants with immediate hypersensitivity reactions to foods (milk, egg, or peanut), occurring at the first-known exposure. Each developed symptoms within the first hour, but these generally settled within 2 hours. Sensitisation to the food concerned was demonstrated by positive immediate allergen skin prick tests in every case. Symptoms experienced included irritability, erythematous rash, urticaria, angio-oedema, vomiting, rhinorrhoea, and cough. Five infants were being followed prospectively and 4 were clinically tolerant of the food by age 16 months. The most likely route of sensitisation was via breast milk. None of the infants experienced similar reactions while being breast fed, suggesting that the reaction was dose dependent. As 5 out of a group of 80 infants being followed prospectively developed an immediate reaction at their first known exposure to a food, this appeared to be a not uncommon presentation of food hypersensitivity in infancy.

Allergic reactions to food colors have been known since 1958. Reactions to tartrazine, our example, include generalized pruritus, urticaria, angioedema, paresthesias, vomiting, migraine, rhinorrhea and nasal obstruction, coughing, asthma attacks and purpura. Many patients who are allergic to antiinflammatory drugs such as acetyl-salicylic acid and indomethacin show cross-reaction to tartrazine. Doses producing these reactions range from minimal amounts up to 750 mg. Symptoms appear after periods of time ranging from minutes to 6 to 14 hours. In view of these facts (some of which represent a threat to the patient's life), additives, colouring matter, etc, do not usually appear in product labels or specifications, or in handbooks or catalogues used in practice. We drew up a list of drugs which may contain food dyes and coloring matter, yellow No. 5. A letter was written to 233 laboratories of which 159 (68%) replied. 72 (45%) in the affirmative and 87 (55%) in the negative, 74 (32%) did not reply.

Clinical effect of acetylspiramycin, one of macrolide antibiotics, primary atypical pneumonia and serologically proven Mycoplasma pneumonia in children was studied. Twenty-four cases of these pneumonia (PAP 11, MP 13) in children were selected and acetylspiramycin was given in dose of approximately 30 mg/kg/day orally. Clinical response was evaluated in terms of improvement in fever, cough and chest X-ray. Clinical response was excellent in 4, good in 5, fair in 14 cases and none in 1 case. No definite adverse effect was observed, however 3 cases showed skin rashes. Two cases showed evanescent small erythematopapulous rash and 1 case developed urticaria on the 2nd to 4th day after this drug was given. These skin rash seemed one of the manifestation of Mycoplasma infections, rather than adverse side effect. One case showed elevated transaminase activity before acetylspiramycin was given and improved on the 2nd week, although this drug was continued. No other side effect was observed. We were able to use acetylspiramycin only in the form of 200 mg tablet and difficulty of the administration was encountered in children under 5 years of age. Other form (dry syrup, etc.) of this drug should be considered for the clinical use in children. In conclusion, acetylspiramycin was effective and safe for the treatment of primary atypical pneumonia and Mycoplasma pneumonia.

Acid anhydrides are low-molecular-weight chemicals known to cause respiratory irritancy and allergy. Skin allergy has on rare occasions been reported. 2 workers contracted hives and itching on uncovered skin after 2 months exposure to methyltetrahydrophthalic anhydride (MTHPA) and methylhexahydrophthalic anhydride (MHHPA), to which they had airborne exposure. Later, the patients also developed conjunctivitis, rhinitis, sore throat, cough or asthma. In addition to MTHPA, 1 worker was also exposed to unsaturated polyester resin (UP). Both patients' immediate allergy to MTHPA and MHHPA was verified by positive prick tests to MTHPA and MHHPA, conjugated with human serum albumin (HSA), and positive radioallergosorbent tests (RASTs) to these anhydrides. On prick testing, both patients also reacted to a phthalic anhydride (PA)-HSA-conjugate and 1 of the patients to UP-HSA-conjugate. Specific immediate allergy to UP was shown by RAST. RAST inhibition with MTHPA, MHHPA and UP-resin conjugates confirmed IgE-mediated allergy and cross-reactivity between anhydrides. Our patients had developed airborne contact urticaria caused by phthalic anhydrides, in addition to respiratory allergy. Phthalic anhydride contained in the UP resin was possibly responsible for the immediate reaction of the skin.

The purpose of the present phase IV multicentre trial was to evaluate general patient tolerance to Omnipaque 350 mgI/ml (iohexol) supplied in polypropylene containers compared to that of the same product supplied in routinely used glass vials, with emphasis on allergy-like adverse events. Polypropylene is a pure plastic material with practically no additives, and has been tested in vitro as a contrast medium packaging material for several years. Handling of these containers is easier and safer than handling of glass vials. Iohexol was administered to 1481 patients undergoing urography (741 patients in the glass vial group, 740 in the polypropylene container group), all of whom successfully participated in the trial. Six centres, representing four European countries, participated. Patients were randomized to receive iohexol from either polypropylene containers or traditional glass vials according to a double blind, parallel design. Pre-established inclusion and pre-admission exclusion criteria were followed, as well as routine procedures for preparation of the patients and conduct of the urography examinations at each hospital. Patient tolerance was assessed by recording all adverse events experienced over a period of up to 1 h after the procedure. Allergy-like events were defined as coughing, sneezing, nausea, vomiting, urticaria or itching. No adverse events were experienced by 56.5% of the patients in the glass vial group, nor by 58.0% of those in the polypropylene group. Discomfort (mainly a sensation of warmth) was reported by 39.4% and 38.6% of the patients, and adverse events other than discomfort by 7.4% and 5.9% of the patients, respectively. There seemed to be a correlation between the speed of injection and the frequency of discomfort (an increase with increasing speed), both of which varied a lot between centres. There was no significant difference in the incidence of allergy-like events between the two groups. Such reactions were seen in 2.0% of patients in the glass vial group and 1.9% of those in the polypropylene container group. There was no significant difference between the patients' tolerance to iohexol supplied in traditional glass vials or in polypropylene containers. Therefore, the new polypropylene container can be recommended as a container for Iohexol.

Omeprazole is a substituted benzimidazole that has gained widespread use in the treatment of acidic and peptic ulcer disease. Adverse events with the drug are rare and involve mainly the gastrointestinal and central nervous systems. Skin inflammation, urticaria, pruritus, alopecia, and dry skin have been reported in 0.5-1.5% of patients. To date, no published report has linked angioedema with omeprazole. We report a case of a 34-year-old woman with cellulitis, ulcerative erosive esophagitis, and gastric and duodenal ulcers who developed several hypersensitivity reactions characterized by shortness of breath, wheezing, cough, mild angioedema, and total body urticaria and pruritus. These symptoms correlated with the addition of omeprazole to her regimen and the timing of its administration. A previous case report prompted a rechallenge with enteric-coated omeprazole granules removed from the capsule shell. Recurrence of the adverse events suggested an allergy to the drug itself and not the capsule. Angioedema can be a life-threatening allergic reaction requiring immediate treatment. Rechallenge using omeprazole with or without the capsule shell should be done only in a hospital setting where prompt action can be taken in the event of an emergency.

In this investigation 98 children (median age 24 months) with cows' milk allergy (CMA) were studied over a median period of 2 years to see whether acquisition of clinical tolerance to cows' milk was associated with the changes in levels of IgG and IgE anti-cows' milk antibodies, and skin test reactivity to a cows' milk extract. Two groups of CMA patients were examined. The first were IgE sensitized and responded rapidly to small volumes of cows' milk with urticaria, and/or exacerbations of eczema, and/or wheeze, and/or vomiting (n = 69). The second, a late reacting group (n = 29) demonstrated coughing, diarrhoea, eczematoid rashes, and/or a combination of these which developed more than 20 hr after commencing normal volumes of cows' milk. Significant immunological changes were confined to the 69 IgE sensitized immediate-reacting-group of patients. Of these, there were 15 children who achieved clinical tolerance to cows' milk and they showed a significant fall in the levels of skin test reactivity to cows' milk over the study period (P < 0.01). In addition, these 15 children had lower serum IgE antibodies to cows' milk proteins both at the outset and the final follow-up compared with the 54 patients whose CMA persisted. No consistent change in the IgG antibody responses to cows' milk proteins was seen in either group of patients over the study period. The findings suggest patients with immediate type hypersensitivity to cows' milk proteins whose disease persists for more than 2 years have a more severe dysregulation of IgE synthesis to cows' milk proteins from the outset.(ABSTRACT TRUNCATED AT 250 WORDS)

Allergic diseases affect at least 15% of the population and are the cause of much ill-health. 'Clinical immunology and allergy', the term used by the Department of Health in England and Wales for this area of specialization, is recognized as a separate specialty of medicine under the National Health Service. Many organ-based hospital consultants (e.g. chest physicians) have allergy as a special interest or subspecialty. Allergists deal largely with 'itch, sneeze, cough and wheeze' and so are experts in: summer hay fever (seasonal, allergic, conjunctivorhinitis); perennial rhinitis (symptoms of a 'permanent cold'); allergic asthma (including occupational asthma); allergy to stinging insects (especially wasps and bees); allergy to drugs; allergy-related skin disorders, i.e. urticaria, angioedema, atopic eczema and contact dermatitis; food allergy and food intolerance; anaphylaxis (acute generalized allergic reaction); evaluating the role of allergy in non-specific/polysymptomatic illness. Children with allergic disease should be under the overall care of a paediatrician since the progression of allergies in children differs from that in adults. Good allergy practice involves teamwork by doctors, nurses and dietitians. The investigation of allergy patients includes skin tests and challenge procedures (e.g. food allergy tests) as well as various specialized laboratory investigations. Good clinical practice by providers and the effective use of allergy services by purchasers should improve prognosis and cut costs of treatment in allergic disease.

We examined whether a prick test was a valuable method in comparison with an intradermal skin test for predicting an anaphylactoid reaction to intravenous injection of fluorescein solution. Fifteen hundred cases were tested. The number (rate) of positive reactions to the prick test with 10% and 1.0% fluorescein solution was 2 (0.1%) and 0 (0.0%), respectively. In contrast, positive reaction to the intradermal skin tests with 10% and 0.1% fluorescein solution was observed in 686 cases (45.7%) and 13 cases (0.9%), respectively. Fluorescein angiography (FAG) was performed in 1,499 of the 1,500 cases. Adverse reactions such as nausea, cough, cold sweat, urticaria, and shock were noted in 85 cases (5.7%). Typical anaphylactoid shock occurred in one case (0.07%), which was one of the two cases positive to the prick test with 10% fluorescein. In the other positive prick test case, FAG was cancelled because of the high probability of anaphylactoid shock. The results suggest that a prick test with 10% fluorescein solution can markedly cut down the false positive reactions and can be a useful test for the prospective diagnosis of anaphylactoid reactions to intravenous fluorescein administration.

A case of contact urticaria associated with a serous rhinitis, dyspnea, wheezing, and a dry cough appearing after the application of a hair conditioner on the scalp is reported. Prick test results with the conditioner diluted at 1/16 and 1/8 were strongly positive (+3), as well as a prick test (+3) with one component of the conditioner called "hydrolyzed proteins," which contained hydrolyzed bovine collagen and stearyl trimethylammonium chloride.
