In the literature there are a few occasional case reports of rheumatic manifestations following vaccination. The link between vaccination and musculoskeletal complaints was established on the grounds of the chronological succession between the two events. The occurrence of an individual genetic predisposition has been stressed many times. With regard to immunopathological mechanisms, it has been proposed the vaccination as a trigger of a very autoimmune disease or an immune complex-induced disease. In this paper we describe two females who underwent vaccination against hepatitis B virus. One complained of polyarticular pain that, even if self-limiting, was accompanied by the positivity of RA-test and Waaler-Rose reaction; the other showed migratory arthritis, urticaria and oedema of the glottis and the upper lip, all successfully treated with a short course of corticosteroids. We think these reports are of interest at the time when vaccination against hepatitis B virus is becoming a mass practice.

Iomeprol (B16880) is a new non-ionic tri-iodinated radiographic contrast medium. It was the aim of this double blind randomized phase III clinical trial to compare the local and systemic tolerance of iomeprol-300 (300 mg I ml-1) with the commercially available iopromide-300 (300 mg I ml-1) in a group of 198 patients needing intravenous urography. The contrast medium was injected rapidly into an antecubital vein within 2-3 min in most cases, using a standard dosage of 1 ml kg-1 body weight. The proportion of patients with an allergic diathesis was 25% in the iomeprol group and 17.3% in the iopromide group. There were no life-threatening adverse reactions. Eight patients (8%) receiving iomeprol and 6 (6.1%) receiving iopromide had a sensation of heat related to the injection of contrast medium. Only one patient (1%) in the iomeprol group and two patients (2%) in the iopromide group noted pain on injection. Although the incidence of all other side-effects was relatively high (7% after iomeprol and 11.2% after iopromide) these reactions were generally harmless. The most common symptom was nausea and/or vomiting, which occurred with the same incidence (5%) in both groups. Only one patient in each group developed urticaria or erythema. Vital parameters remained essentially unchanged in all patients. The results suggest that iomeprol is a safe contrast medium, with a tendency to produce fewer side effects than iopromide, which is known to be particularly well tolerated.

The number of arthroscopic procedures performed annually for the management of intraarticular injuries has grown at an exponential rate. Whether done with the patient under general anesthesia or local anesthesia supplemented with intravenous sedation, it is common practice to postoperatively inject each portal as well as the joint with a local anesthetic to provide pain relief in the transition to the recovery room and discharge after outpatient surgery. To our knowledge, no previous reports of localized urticaria and delayed hypersensitivity reaction have been reported in the postarthroscopy setting. We are reporting a case of delayed hypersensitivity reaction and urticaria of the knee that presented after bupivacaine (Marcaine) injection of arthroscopic portals after routine meniscectomy.

This study presents the clinical and laboratory findings of a novel syndrome associated with eosinophilia. Two young women presented with marked eosinophilia, and large, non-tender compressible articular nodules arising from the tenosynovium of extensor tendons, dermatitis, episodic swelling of the hands and/or feet and pain in adjacent muscles and joints. Tissue specimens were examined by routine haematoxylin and eosin staining, immunofluorescent staining for eosinophil granule major basic protein (MBP) and rhodamine-avidin or tryptase staining for mast cells. Plasma levels of MBP and eosinophil-derived neurotoxin (EDN) were quantitated by immunoassay. The first patient presented in 1967 at the age of 20 and had, in addition to nodules and eosinophilia, dermographism, recurrent episcleritis and axillary urticaria. Biopsy of a nodule showed tenosynovitis with necrotizing granulomas, non-specific vasculitis, eosinophils and eosinophil degranulation as shown by extracellular deposition of eosinophil granule MBP. Her symptoms responded to low-dose, alternate-day prednisone and have remained quiescent over the past 15 yr. The second patient presented in 1990 at the age of 28 with generalized pruritic dermatitis for 15 yr, eosinophilia for 2 yr, subcutaneous nodules and non-limiting pain in several joints. Biopsy of a nodule showed chronic mild tenosynovitis, numerous eosinophils and extracellular deposition of MBP. She remains untreated. Serum IgE values and plasma levels of MBP and EDN were elevated in both patients; mast cells were numerous in their synovial tissue. Based on their clinical courses, these patients reveal the existence of a distinctive, relatively benign eosinophilic disorder with good long-term prognosis.

Occasionally, a dental patient presents his/her dentist with a history of hypersensitivity to local anesthetic agents. The symptoms may include immediate reactions to the injection procedure (dizziness, shortness of breath, tachycardia, etc), or delayed reactions to the anesthetic (swelling, urticaria, etc). Although the true incidence of local anesthetic allergy is low, such a history often involves the patient's anxiety regarding the use of the drug in question, and the dentist's apprehension to treat the "problematic" patient. In such cases, hypnosis can play a major role in controlling pain and the associated distress. In the present article, the method concerning the implementation of hypnosis to induce local anesthesia is described and illustrated through case demonstrations.

Previous studies show that oral antihistamines affect the weal and flare response to intradermal injections of the inflammatory mediators platelet-activating factor (PAF) and bradykinin (BK). The aim of this study was to compare the effects of terfenadine (an H1-antagonist) and cimetidine (an H2-antagonist) on weal and flare responses to PAF and BK in healthy non-atopic human volunteers. The effects of doxepin on PAF responses were investigated, as there is evidence that doxepin may have direct anti-PAF effects in addition to its known antihistaminic actions. Terfenadine significantly reduced weal and flare responses to PAF (mean reduction 53 and 73%, respectively) and flare responses to BK (mean reduction 78%) but had no effect on weal responses to BK. Doxepin significantly reduced both weal and flare responses to PAF (mean reduction 43 and 68%, respectively, at higher doses of PAF). Cimetidine had no effect on weal or flare responses to PAF or BK. These findings suggest that the flare response to intradermal BK is mediated via histamine release while the weal response is not. The effects of the various antagonists of PAF-induced responses suggest that its effects too may be mediated via histamine, the similarity of the effects of terfenadine and doxepin on these responses indicating that the effects of doxepin may be due to its known antihistamine activity rather than to any specific PAF-antagonistic properties. Platelet-activating factor (PAF) is a phospholipid which is released from a wide range of cell types and also from vascular endothelium. PAF is formed by the conversion of ether-linked phospholipids initially to the biologically inactive lyso-PAF and then by acetylation to PAF. Intradermal injection of PAF in human skin causes vasodilatation and increased vascular permeability, producing a weal and flare response with accompanying pruritus. Bradykinin (BK) is a vasoactive polypeptide formed by the action of enzymes known as kallikreins on inactive precursors called kininogens. Its effects include an increase in blood flow and vascular permeability and stimulation of the release of prostaglandins and histamine. On intradermal injection in human skin it causes a weal and flare response with associated pain rather than pruritus. Previous studies have suggested that the weal and flare response to PAF may be mediated in part by histamine release. Given that BK is known to cause histamine release it appears possible that the responses to both compounds may be modified by conventional antihistamines. Experiments based on this premise have found that antihistamines have a pronounced effect on the flare response to PAF but a less marked effect on weal responses. The weal response to BK was unaffected by systemic antihistamines but studies have produced conflicting results with regard to effects on the flare response. The aim of this study was to compare the effects of terfenadine (an H1-antagonist) and cimetidine (an H2-antagonist) on PAF- and BK-induced weal and flare responses in healthy, non-atopic human volunteers. Based on the treatment of cold urticaria it has been suggested that doxepin, which has known H1- and H2-antagonistic effects, may in addition show specific anti-PAF activity. We compared the effects of doxepin on PAF-induced intradermal responses with those of terfenadine and cimetidine in this study.

The impact of chronic urticaria (CU) on the quality of life is undocumented. We assessed quality of life in patients with CU, including patients with associated delayed pressure urticaria (DPU). One hundred and forty-two out-patients completed self-administered questionnaires: a disease-specific, purpose designed questionnaire, and the Nottingham health profile (NHP). Many patients reported problems attributable to their skin condition in facets of everyday life including home management, personal care, recreation and social interaction, mobility, emotional factors, sleep, rest and work. The NHP part I scores showed restriction in the areas of mobility, sleep, energy, and demonstrated pain, social isolation and altered emotional reactions. Part II of the NHP showed that patients experienced difficulties in relation to work, looking after the home, social life, home relationships, sex life, hobbies and holidays. The patients with DPU had significantly more problems with mobility, gardening and choice of clothing than the uncomplicated CU patients. They also suffered more pain, had more problems with work and were more restricted in their hobbies.

A case of anaphylaxis following skin tests for airborne allergens in a 25-year-old female patient diagnosed with bronchial asthma and allergic rhinitis, is presented. The purpose of this paper is to alert against severe systemic reactions related to skin tests. The reaction occurred 15 minutes after administration of various airborne allergens (pollens, air molds, and house dust), and the symptoms were: hypogastric pain, transvaginal bleeding, generalized urticaria, and bronchospasm. Immediate treatment consisted of antihistamines, bronchodilatators and steroids; the symptoms subsided in 12 hours. We conclude that skin testing can give rise to severe systemic reactions which should be identified and treated immediately by trained physicians and ancillary personnel, and that these tests should be avoided when pregnancy is suspected.

Povidone is a synthetic polymer mainly used as a dispersing or suspending agent for many pharmaceutical products. It is also used as a carrier for iodine. In many countries it is not mandatory its inclusion in drug labels so many adverse effects may be under diagnosed. Povidone-iodine used as a topical antiseptic solution may produce allergic contact dermatitis and irritation. Povidone, when systemically administered may deposit in tissues causing local lesions and pain. Three cases of immediate hypersensitivity to this agent have been reported. We present a patient who developed generalized urticaria and angioedema immediately after the first topical use of Betadine (povidone-iodine) on a right arm wound. The positive skin prick test to Betadine and povidone extract and the demonstration of serum specific IgE to povidone, confirmed an IgE-mediated hypersensitivity.

3F8 is an IgG3 murine monoclonal antibody directed against the ganglioside GD2. In a phase II study, 3F8 was administered i.v. to 16 patients (pts) who had stage 4 neuroblastoma. Response was seen in bony lesions (2 of 7 pts) and marrow (3 of 8 pts). Acute toxicities of pain, fever, urticaria, hypertension, hypotension and anaphylactoid reactions were self-limited and manageable. Three pts are long-term survivors between 79-130+ months after 3F8 treatment without additional systemic therapy and no delayed neurological complications. The potential benefits of 3F8 when added to chemoradio-therapy warrant further investigation.
