RESUMO
We report the rare case of an acalculous, gangrenous cholecystitis on a, previously healthy, outpatient COVID-19 adult. The 53-year-old patient presented to the emergency department due to epigastric pain and fever and was admitted to the COVID-19 department. Due to clinical and laboratory deterioration, a computed tomography scan was performed that confirmed the diagnosis of acalculous cholecystitis. The patient was submitted to laparoscopic cholecystectomy. Intraoperatively, a gangrenous gallbladder was identified. Immunohistology validated the presence of specimen wall vasculitis and vessel thrombosis.
RESUMO
BACKGROUND: Loss of normal cell cycle control is an early event in the evolution of cancer. The expression of cyclin-dependent kinase (CDK) inhibitors p16 and p27 has been previously associated with progression of prostate cancer (PC). 70 patients diagnosed with early stage PCwere treated with radical prostatectomy (RP) at our institution and their tumor specimens were immunohistochemically evaluated for expression of p16 and p27. Available clinical data of time to PSA recurrence were correlated with the examined parameters and combined with pre-operative PSA level, Gleason score and pathological TNM (pT) stage assessment. RESULTS: Nuclear overexpression of p16 was not associated with time to biochemical failure (BF) (p = 0.572). Same was the case for nuclear p27 overexpression (p = 1.000). Also, no significant correlations were found between either p16 or p27, and pre-operative PSA level, pT stage and Gleason grade. pT stage emerged as the only independent prognostic factor for biochemical recurrence (p = 0.01). CONCLUSIONS: These data question previously reported data supporting the prognostic relevance of both p16 and p27 proteins in early PC.
