Peritoneal dialysis-associated polymicrobial peritonitis with slow onset after root canal treatment: the first case and review of the literature.

Background: Peritoneal dialysis (PD)-associated peritonitis is linked to an increased risk of mortality and catheter removal, with a higher incidence of these risks observed in polymicrobial peritonitis compared with single-organism infection. In PD patients, invasive procedures can cause peritonitis, typically within 7 days, through transient bacteremia. Although dental procedures are widely recognized as a cause of transient bacteremia, only a limited number of cases involving PD-associated peritonitis after dental procedures, and no cases of polymicrobial peritonitis, have been reported.

Evaluation of acetic acid solution for rehydration of mummified skin tissues.

Histological characteristics such as transverse striation of skeletal muscle are preserved in mummified tissues compared with autolyzed or putrefied tissues, providing histological or forensic information upon histological analysis. However, processing dried tissue for histological examination is difficult due to its hardness. In addition, the histological architecture may be altered during the dehydration process, leading to alternation of the staining appearance.

Polycythemia secondary to bilaterally enlarged kidneys in T-Cell acute lymphoblastic leukemia: a case report and literature review.

Background: Polycythemia is a rare disease that can cause hypertension. Secondary polycythemia with increased production of erythropoietin (EPO) is associated with several kidney diseases, including hydronephrosis and cystic disease. However, there have been no reports of a case presenting with polycythemia secondary to bilateral nephromegaly caused by renal infiltration of T-cell acute lymphoblastic leukemia (T-ALL).

Solid Predominant Histology and High Podoplanin Expression in Cancer-Associated Fibroblast Predict Primary Resistance to Osimertinib in -Mutated Lung Adenocarcinoma.

Introduction: Resistance to EGFR tyrosine kinase inhibitors is influenced by tumor-intrinsic and -extrinsic factors. We investigated the impact of tumor cell histology and tumor microenvironment on the efficacy of osimertinib.

Methods: We evaluated surgically resected adenocarcinoma from patients treated with first-line osimertinib at the National Cancer Center Hospital East (2016-2023), evaluating clinicopathologic characteristics, tumor cell histology, podoplanin expression in cancer-associated fibroblasts (CAFs) identified by immunohistochemistry, and outcomes.
