1/2. Metallic taste: an unusual reaction to botulinum toxin A.BACKGROUND: Botulinum neurotoxin formulations are safe and effective agents for the treatment of facial rhytides. OBJECTIVES: A patient is described who complained of metallic taste after each treatment with botulinum toxin A (BTX-A). RESULTS: The sensation of metallic taste diminished after successive treatments with BTX-A, despite adequate dosing for cosmetic purposes. CONCLUSION: Metallic taste is associated with the use of numerous medications; however, the pathogenesis remains unclear. Alteration in zinc metabolism, which may occur with BTX-A administration, has been suggested as a possible mechanism. Although this is the first known report of dysgeusia after BTX-A, physicians and patients may be reassured that the taste alteration was self-limited and was not significantly problematic for the patient in our case.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
2/2. Post-yersinotic Reiter's disease in a physician treated with osmium tetroxide.A case of general yersinosis in a male physician is described. Most probably the infection was acquired nosocomially in a paediatric ward. The infection affected several organs including the liver, but osmium tetroxide was nevertheless used to perform chemical synovectomy in a knee joint suffering from active arthritis. The arthritis was cured, and the already existing liver affection did not progress. The only complaint from the patient, months after the osmic acid injection, was a strong metallic taste on the tongue. More than a year after the intra-articular injection, the metallic taste disappeared. The amount of osmium in the patient's blood was then calculated to be less than 100 molecules of osmium per ml blood.- - - - - - - - - - ranking = 5keywords = physician (Clic here for more details about this article) |
