Clinical case reports can be important sources of information for alerting health professionals to the existence of possible health hazards. Isolated case reports, however, are weak evidence of causal relationships between exposure and disease because they do not provide an indication of the frequency of a particular exposure leading to a disease event. A database of chemicals causing allergic contact dermatitis (ACD) was compiled to discern structure-activity relationships. Clinical reports repre sented a considerable fraction of the data. Multiple Computer Automated Structure Evaluation (MultiCASE) was used to create a structure-activity model to be used in predicting the ACD activity of untested chemicals. We examined how the predictive ability of the model was influenced by including the case report data in the model. In addition, the model was used to predict the activity of chemicals identified from clinical case reports. The following results were obtained: • When chemicals which were identified as dermal sensitizers by only one or two case reports were included in the model, the specificity of the model was reduced. • Less than one half of these chemicals were predicted to be active by the most highly evidenced model. • These chemicals possessed substructures not pre viously encountered by any of the models. We conclude that chemicals classified as sensitizers based on isolated clinical case reports be excluded from our model of ACD. The approach described here for evaluating activity of chemicals based on sparse evidence should be considered for use with other endpoints of toxicity when data are correspondingly limited.

AbstractHypersensitivity reactions including IgE-mediated and delayed cell-mediated reactions to aminoglycosides, clindamycin, linezolid, and metronidazole are rare. For aminoglycosides, allergic contact dermatitis is the most frequent reaction for which patch testing can be a useful step in evaluation. For clindamycin, delayed maculopapular exanthems are the most common reactions. There are case reports of clindamycin associated with drug rash with eosinophilia and systemic symptoms (DRESS), acute generalized exanthematous pustulosis (AGEP), acute febrile neutrophilic dermatosis, and symmetrical drug-related intertriginous and flexural exanthema (SDRIFE). For linezolid, cases of hypersensitivity were exceedingly rare and included urticaria, angioedema, anaphylaxis, delayed rashes, and DRESS. For metronidazole, only rare cases were found across a broad spectrum of reactions including allergic contact dermatitis, fixed drug eruption, angioedema, anaphylaxis, serum sickness-like reaction, SJS/TEN, AGEP, SDRIFE, and a possible case of DRESS. IgE-mediated reactions and anaphylaxis to these types of antibiotics are uncommon, and reports of skin testing concentrations and desensitization protocols are largely limited to case reports and series. Non-irritating skin testing concentrations have been reported for gentamycin, tobramycin, and clindamycin. Published desensitization protocols for intravenous and inhaled tobramycin, oral clindamycin, intravenous linezolid, and oral and intravenous metronidazole have also been reported and are reviewed.

Abstract Acrylates are plastic materials formed by the polymerization of monomers, which are recognized as powerful sensitizers that may cause allergic contact dermatitis both in occupational and non-occupational environment. In the occupational setting, the most exposed workers are the dentists, dental technicians, prosthesis technicians, printers, painters, fiberglass workers and nail technicians. We describe four cases of occupational allergic contact dermatitis in nail technicians caused by acrylic compounds that illustrate numerous clinical manifestations. Clinical manifestations ranged from edema, erythema, scaling and fissuring fingertips to erythematous patches around the chin, mandible and abdomen. Patch testing results revealed positive reaction to 2-hydroxyethyl methacrylate in all patients. Of the four patients, two changed jobs, one stopped exposure because of pregnancy and one patient continued working, showing no improvement, despite undergoing treatment. These cases underline the importance of improvement of preventive measures in the workplace.
