RESUMO
Nicolau syndrome (NS), also referred as embolia cutis medicamentosa and livedo-like dermatitis, is an uncommon complication followed by drugs administered intramuscularly, intraarticularly or subcutaneously. In this case report we present a case of a 65-year-old lady who had a single dose of diclofenac sodium as an intramuscular injection in her left buttock due to back pain that led to developing what known as NS. She was treated with surgical debridement, drain insertion and skin approximation with antibiotics for 2 weeks with daily sterile dressing. The wound healed completely with scarring. NS is a preventable outcome, thus, proper procedures and precautions should be taken during intramuscular medication administration. Healthcare providers should avoid unnecessary injections, be familiar with the complication and consider it as a potential diagnosis for severe localized pain after any injection.
RESUMO
Despite its rarity, AIHA can be associated with COVID-19. It should be suspected in a patient with recent COVID-19 presenting with unexplained anemia.
RESUMO
BACKGROUND: Since introducing the SARS-CoV-2 vaccination, different adverse effects and complications have been linked to the vaccine. Variable neurological complications have been reported after receiving the COVID-19 vaccine, such as acute encephalopathy. CASE PRESENTATION: In this report, we describe a 32-year-old previously healthy man who developed acute confusion, memory disturbances, and auditory hallucination within 24 hours from getting his first dose of the COVID-19 Moderna vaccine.EEG showed features of encephalopathy, CSF investigations were nonspecific, and MRI head did not depict any abnormality. He received five days of ceftriaxone and acyclovir without any benefit. DISCUSSION: Extensive workup for different causes of acute encephalopathy, including autoimmune encephalitis, was negative. Also, Our patient improved dramatically after receiving methylprednisolone, supporting an immune-mediated mechanism behind his acute presentation. Accordingly, we think the COVID-19 vaccine is the only possible cause of our patient presentation, giving the temporal relationship and the absence of other risk factors for encephalopathy. CONCLUSION: the clinician should be aware of the possible neurological complications of the different COVID-19 vaccines. Further research is needed to clarify the pathophysiology of such complications.
