RESUMO
Bilateral synchronous renal cell carcinoma (RCC) is rare, especially in sporadic rather than familial cases. While immunotherapy has improved prognosis, RCC remains a diagnosis with significant morbidity and mortality, particularly pronounced in patients with sarcomatoid RCC (sRCC). We describe a case of a patient with bilateral, synchronous, nonfamilial RCC, with and without sarcomatoid features and differing genetic markers, who demonstrated a pathologic response after neoadjuvant nivolumab and ipilimumab. The patient then had radical left nephrectomy and partial right nephrectomy followed by adjuvant nivolumab and cabozantinib, after which the patient had no evidence of disease. Our patient's illustrative case shows the potential therapeutic value of immunotherapy even in sRCC, the disease's most aggressive clinical subtype.
RESUMO
Aspirin should not be used to treat acute febrile viral illness in children. (Strength of Recommendation [SOR]: C, based on case-control studies). Although no causal link has been proven, data from case-control and historic cohort studies demonstrate an association between aspirin use and Reye syndrome. The risk of Reye syndrome decreases with age, becoming extremely rare by the late teenage years. Other nonsteroidal anti-inflammatory drugs are effective antipyretics and are not associated with the constellation of symptoms seen in Reye syndrome, which includes nausea, vomiting, headache, excitability, delirium, combativeness, and coma. Aspirin use in children younger than 19 years should be limited to diseases in which aspirin has a proven benefit, such as Kawasaki disease and the juvenile arthritides. (SOR: C, based on expert opinion).
