Transvaginal Ultrasonography for Detection of PID‐Related Adhesions: A Case Report

open access: yesAustralasian Journal of Ultrasound in Medicine, Volume 29, Issue 3, August 2026.
ABSTRACT Background Diagnosis of acute and chronic pelvic inflammatory disease continues to be a challenge despite advances in investigative procedures. Complications of PID include infertility, chronic pelvic pain and ectopic pregnancy. Currently, transvaginal ultrasonography is primarily used to detect tubo‐ovarian abscesses (TOA) or pyosalpinx.

Ethnic Differences in the Association Between SOD2 rs4880 and Hepatotoxicity in Pediatric Acute Lymphoblastic Leukemia: A Report From the REDIAL Consortium

open access: yesPediatric Blood &Cancer, Volume 73, Issue 7, July 2026.
ABSTRACT Treatment‐associated hepatotoxicity (TAH) is a common complication of pediatric acute lymphoblastic leukemia (ALL) treatment, but genetic risk factors remain poorly understood. We evaluated the SOD2 rs4880 variant in 544 children with ALL at Texas Children's Hospital. After adjusting for demographic and clinical covariates, the rs4880 C allele
