Embryonic-type neuroectodermal tumors (ENTs) arising from testicular germ cell tumors (GCTs) is a relatively common type of somatic transformation in GCTs with poor prognosis and limited therapeutic options, particularly when patients develop disease recurrence or metastasis. Knowledge of key events driving this transformation is limited to the paucity of comprehensive genomic data. We performed a retrospective database search in a CLIA- and CAP-certified laboratory for testicular GCT-derived ENTs that had previously undergone NGS-based comprehensive genomic profiling during the course of clinical care.

The 2020 American Heart Association Guidelines advise not to perform mitral valve replacement (MVR) during septal myectomy (SM) to alleviate outflow obstruction. This study aims to review outcomes after concomitant mitral valve (MV) intervention versus SM alone. We conducted a comprehensive literature search across Embase, PubMed, and Scopus.

Purpose: The purpose of this case series is to report three cases of exposed, unburied polytetrafluoroethylene (Gore-tex) sutures used for scleral fixated intraocular lenses and their management, including failure of pericardial patch and success of irradiated corneal patch. This series aims to inform management options for this uncommon adverse event.

Observations: A retrospective case series was conducted of three patients who presented at a tertiary care center with exposure of unburied Gore-tex sutures used for fixation of intraocular lens.

Importance: Middle ear effusion (MEE) is the primary cause of conductive hearing impairment among children, predominantly occurring up to the age of two years. The gold standard for detecting MEE is tympanometry (Grayson-Stadler, Eden Prairie, Minnesota). This study explores a less costly alternative, the video otoscope (Inventis S.

Hormone-dependent cancers (HDCs) share several risk factors, suggesting a common aetiology. Using data from genome-wide association studies, we showed spatial clustering of risk variants across four HDCs (breast, endometrial, ovarian and prostate cancers), contrasting with genetically uncorrelated traits. We identified 44 multi-HDC risk regions across the genome, defined as overlapping risk regions for at least two HDCs: two regions contained risk variants for all four HDCs, 13 for three HDCs and 28 for two HDCs.
