People who use drugs, particularly injection drug users (IDUs) are known as the major source of hepatitis C virus (HCV) infection. This study was performed to determine the prevalence of HCV infection using rapid point-of-care testing and to assess liver fibrosis by non-invasive lab tests among addict populations of Mashhad, Iran. ⋯ HCV infection screening using rapid tests and examining liver fibrosis by non-invasive lab tests appear to be practicable and useful among poor populations in settings such as drug treatment centers.

The scarcely reported hematogenous rectal metastases from breast cancer are rare and the diagnosis is challenging. They may be recognized before, concomitantly with, or after the diagnosis of the primary site of breast cancer. Invasive lobular cancer is the histological type more frequently described, and most of the affected patients have a late diagnosis. ⋯ We describe a middle-aged woman with advanced rectal metastases of unsuspected breast cancer found during the evaluation of manifestations due to intestinal implants. One must highlight long-term follow-up of breast cancers even if seeming in remission. The aim of this report is to enhance the suspicion index of primary health care workers.

Multicenter Study
Clinicopathological, Immunohistochemical, and PMS2 Gene Expression Profiling of Patients with Sporadic Colorectal Cancer.
The DNA mismatch repair (MMR) system is one of the molecular pathways involved in colorectal cancer (CRC) carcinogenesis that consists of several genes, including MLH1 (MutL homolog 1), MSH6 (MutS homolog 6), MSH2 (MutS homolog 2), and MSH3 (MutS homolog 3). The protein encoded by PMS2 (post-meiotic segregation 2) is also essential for MMR. Here, we address the correlation between immunohistochemical and transcriptional expression of PMS2 with the tumor grade and clinical stage of non-hereditary/sporadic CRC disease. ⋯ These findings suggest that PMS2 may provide a potential reliable biomarker for CRC classification by combined immunohistochemical and mRNA analysis.

Post-mortem Histopathologic Findings of Vital Organs in Critically Ill Patients with COVID-19.
The scientific evidence concerning pathogenesis and immunopathology of the coronavirus disease 2019 (COVID-19) is rapidly evolving in the literature. To evaluate the different tissues obtained by biopsy and autopsy from five patients who expired from severe COVID-19 in our medical center. ⋯ Our observations suggest that clinical pathology findings on autopsy tissue samples could shed more light on the pathogenesis, and consequently the management, of patients with severe COVID-19.
