[source] Cross-reactivity among p -amino group compounds in sulfonamide fixed drug eruption: diagnostic value of patch testingCONTACT DERMATITIS, Issue 2 2004P. Tornero We studied 28 patients with fixed drug eruption (FDE) caused by sulfonamide antibiotics to investigate cross-reactivity between sulfonamide derivatives and p -amino compounds and to explore the usefulness of patch testing, as an alternative to controlled oral challenge testing (COCT), in diagnosis within this clinical area. COCT with sulfamethoxazole (SMX), sulfadiazine (SDZ), sulfamethizole (SMZ), furosemide (FU), procaine (PRO) and glipizide (GPZ) was performed. Patch testing (PT) with SMX and SDZ was carried out. In all patients, the diagnosis of FDE was confirmed by positive COCT and allergy to trimethoprim ruled out by COCT. 42.8 and 31.8% of the SMX-induced FDE patients reacted to SMZ and SDZ, respectively. All patients (n = 28) tolerated FU, PRO and GPZ. COCT performed with the 3 sulfonamide antibiotics in 12 patients was positive in 2 subjects with the 3 drugs, in 2 patients only with SMX and SMZ and in the remaining 8, SMX was the only causative drug. PT was positive in 5 of 25 patients positive on COCT. The probability of obtaining a positive PT was higher among patients who had a residual lesion than that among those who lacked this. Cross-reactivity between different sulfonamide antibiotics is thus variable, being most likely between SMX and SMZ. We have found no cross-reactivity between sulfonamide antibiotics and other sulfonamide derivatives or p -amino drugs in FDE. PT is a useful tool in the diagnosis of FDE, especially if there are residual lesions, because it avoided the need for COCT in 20% of patients. [source] Allergic Reactions Due to Ibuprofen in ChildrenPEDIATRIC DERMATOLOGY, Issue 1 2001M. Díaz Jara M.D. We present two instances of adverse reaction to pediatric ibuprofen, an acute urticaria and a fixed drug eruption, with tolerance to acetylsalicylic acid (ASA) and acetaminophen, in what seems to be hypersensitivity to the propionic acid group. Although these reactions are very rare and ibuprofen is still very safe, we think it is important to know about the possible side effects in order to recognize and treat them when they occur. [source] Vulval fixed drug eruption due to paracetamolAUSTRALASIAN JOURNAL OF DERMATOLOGY, Issue 2 2009Catherine Drummond ABSTRACT Paracetamol is a readily available non-prescription analgesic. Fixed drug eruption (FDE) is a well-reported side effect of paracetamol, usually the classic, pigmenting type. In women, it may present as a chronic, erosive vulvitis. We describe a case of FDE due to paracetamol presenting as a chronic erosive vulvitis in an older woman taking multiple medications. Diagnosis was delayed because paracetamol is available without prescription, taken intermittently and may be omitted from the clinical history. Cessation of paracetamol led to prompt resolution of symptoms. Consideration should be given to paracetamol as a cause of FDE presenting as a chronic erosive vulvitis.

[source] Topical provocation in fixed drug eruption due to metamizol and naproxenCLINICAL & EXPERIMENTAL DERMATOLOGY, Issue 4 2004E. Özkaya-Bayazit Summary The aim of this study was to investigate the usefulness of topical provocation in the diagnosis of metamizol- and naproxen-induced fixed drug eruption (FDE). Five patients with metamizol- and four patients with naproxen-induced FDE established by oral provocation were tested with the causative drugs at concentrations of 10%, 20%, and 50% in white petrolatum both on previously involved and uninvolved skin using the occlusive patch test technique. Additionally, four patients with metamizol- and five patients with naproxen-induced FDE, and 20 healthy controls were tested openly with drug preparations in dimethyl sulfoxide (DMSO). Tape-stripping occlusive patch testing in petrolatum remained negative in all. Open testing with drug preparations in DMSO revealed positive results in all four patients tested with metamizol mainly at concentrations of 20%, and in three of five patients tested with naproxen exclusively at concentrations of 50%. No positive reaction was seen on previously uninvolved skin and in healthy controls with any drug concentration and pure DMSO. In conclusion, repeated open testing with concentrations of the drugs up to 50% in DMSO seems to be a reliable test method in metamizol-induced FDE whereas oral provocation is still the most reliable method for naproxen-induced FDE as false negative results were common when testing topically with naproxen. [source] A porcine model for fixed drug eruptions in humans: the case of antipyrine in the Yucatan micropigJOURNAL OF APPLIED TOXICOLOGY, Issue 1 2006Yvonne Pak Abstract To date, there is no acceptable animal model to investigate fixed drug eruptions (FDEs) in humans. We briefly report here observations suggesting that the Yucatan micropig may be a useful animal model for that purpose. During an investigation of antipyrine absorption and disposition, we observed the development of FDEs after intravenous administration of a 1 g dose. Our observations were consistent with those reported in several investigations of humans taking a single dose of antipyrine. To confirm these results, a naďve micropig was challenged. A male uncastrated Yucatan micropig (27.2 kg) was given a 1 g dose of antipyrine intravenously. After 30 days, this pig was rechallenged with the same intravenous dose of antipyrine (1 g). Blood samples were obtained to examine immunological endpoints. During the initial challenge, a fluid plaque (ca. 1,1.5 cm) appeared on the left hip of the pig ca. 6 h after dosing. After the rechallenge, inflamed pink patches were observed at the same sites where the blisters formed initially; however, no blisters re-formed. Changes of neutrophil, lymphocyte and eosinophil levels from baseline were noted 8 h after challenge. The micropig did not seem otherwise affected by the FDEs. These observations suggest that the Yucatan micropig, or swine in general, may be a useful animal model for detecting drugs that may cause FDEs in humans. Copyright © 2005 John Wiley & Sons, Ltd. [source] Neutrophilic fixed drug eruptionAUSTRALASIAN JOURNAL OF DERMATOLOGY, Issue 3 2001Karen L Agnew SUMMARY A 49-year-old man presented with a reproducible, localized amoxycillin,clavulanic acid-induced eruption. The histopathology from lesional skin revealed a neutrophilic dermatosis. These histological findings have not been reported in previous fixed drug eruptions. A brief review is undertaken comparing fixed drug eruption and the group of neutrophilic dermatoses with our case presentation. We propose a new entity of neutrophilic fixed drug eruption.
