RESUMEN
Metal allergies to surgical clips are atypical and often neglected as a differential. It becomes even more unexpected when there is a lack of relevant medical history of the patient reacting poorly to known metals. This study entails the unique finding of newly discovered hypersensitivity to nickel and zirconium, metals commonly found in surgical clips, in a 28-year-old female who underwent laparoscopic cholecystectomy with a cholangiogram.
RESUMEN
Low efficacy has been reported for the treatment of Trichomonas vaginalis with antimicrobial agents other than the 5-nitroimidazole class. Patients with immunoglobulin E (IgE)-mediated hypersensitivity reactions to drugs in this class, including metronidazole and tinidazole, may benefit from a desensitization treatment. We present two patients with past medical histories of IgE-mediated hypersensitivity reactions to metronidazole who were successfully treated with metronidazole using a modified protocol. The first patient was a 39-year-old female diagnosed with trichomoniasis who had a previous reaction to metronidazole characterized by urticaria and pruritus. The second patient was a 53-year-old female who had a history of untreated trichomoniasis due to a previous anaphylactic reaction to metronidazole. Both patients were successfully treated in the intensive care unit (ICU) without signs and symptoms of the reaction. Physicians may use a desensitization protocol for patients with a presumed IgE-mediated hypersensitivity when only the 5-nitroimidazole class is efficacious for the treatment of trichomoniasis.
RESUMEN
Spontaneous chest wall keloid scars can occur without any history of trauma and are rare. Some keloids present with intense pruritus or paresthesia, prompting patients to seek treatment. Currently, many treatment options are available in medicine. However, for this case report a less invasive treatment modality is evaluated. This clinical case report will present Kenalog-40 injections as a treatment option to treat a spontaneous keloid scar. Observation of this treatment option has illustrated a reduction in size and improvement in pruritus, paraesthesia and discoloration.
