RESUMO
Radiation dermatitis is a common side effect of radiotherapy in patients with acute and chronic changes affecting the skin. While acute changes occur within 90 days of radiation exposure, chronic changes manifest thereafter. This paper presents a case of a 70-year-old male with squamous cell carcinoma in situ (SCCIS) on the right zygoma who was treated with superficial radiation therapy (SRT), which resulted in a hypo-pigmented atrophic scar. The scar was successfully treated with a single session of Erbium:YAG laser therapy. The findings highlight the need for improved treatment options for radiation-induced skin changes and demonstrate the efficacy of fractionated laser therapy in addressing SRT-induced dermal atrophy.
RESUMO
Coronavirus disease 2019 (COVID-19) represents a multisystem disease that has caused a devastating global pandemic. The COVID-19 vaccine produced in response to the pandemic has been effective but can have side effects. One well-established condition is the reactivation of herpes zoster (HZ). Various risk factors increase the risk of HZ reactivation such as age, infections, and immunosuppressed states. HZ can have severe complications, including herpes zoster ophthalmicus and postherpetic neuralgia. Here, we present a unique case where a patient experienced HZ reactivation after both primary doses of the COVID-19 vaccine despite receiving early antiviral treatment.
RESUMO
Post-Coronavirus disease 2019 (COVID-19) development of polymyositis is rare, with very few cases documented in the literature. In patients developing vague symptoms after recovery from COVID-19, it is important to investigate all avenues, including the possibility of polymyositis. Polymyositis is typically characterized as symmetrical muscle weakness and histological, electrical, and chemical evidence of muscle injury. Patients identified can be treated with immunosuppressants to return some quality of life and prevent disease progression. In this report, we describe a 58-year-old Caucasian male who presented with symptoms of weakness, myalgias, and arthralgias, six months after recovering from flu-like symptoms of COVID-19. The patient was tested for other autoimmune etiologies and myopathies without positive results. He was treated with prednisone and reported moderate improvement in symptoms. Unfortunately, the patient declined a muscle biopsy or electromyographic testing. According to the criteria for polymyositis set by the Myositis Association and the response to therapy, the patient's symptoms pointed to a likely diagnosis of post-COVID-19 polymyositis.
