Integrated mutational landscape analysis of endometrial stromal sarcoma

Tobias MP Hartwich, Seungji Choi, Ayoung Hwang, Stefania Bellone et autres

Endometrial stromal sarcoma (ESS) is a rare uterine malignancy with limited treatment options. We performed integrated whole-genome, whole-exome, and transcriptome sequencing on 80 ESS tumors, comprising 32 low-grade (LG) and 48 high-grade (HG) tumors, to characterize their genetic landscape. The overall mutation …

Bacterial pericarditis after endobronchial ultrasound-guided transbronchial needle aspiration

Rachna S. Gulati, Håkon Kravdal, Heidi Hoven, Erlend Eriksen et autres

Background: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a valuable diagnostic and staging tool for lung cancer and is generally considered a safe procedure with very low complication rates. Bacterial pericarditis is a rare but serious complication following EBUS-TBNA. Here we describe …

Molecular Landscape of Endometrial Stromal Tumors

Marta Brunetti, Valeria Vitelli, Anca Mihaela Naas, Ane Gerda Zahl Eriksson et autres

PURPOSE The molecular heterogeneity of endometrial stromal tumors (ESTs) is demonstrated by the presence of the same fusion gene in distinct pathologic entities, such as endometrial nodules and low-grade endometrial stromal sarcoma, both exhibiting the JAZ1::SUZ12 chimeric transcript. Given the limited knowledge …

Germline variants in patients diagnosed with pediatric soft tissue sarcoma

Synnøve Yndestad, Hans Kristian Haugland, Dorota Goplen, Dorota Malgorzata Wojcik et autres

BACKGROUND: While soft tissue sarcomas affect younger patients, few studies have assessed the distribution of underlying pathogenic germline variants. PATIENTS AND METHODS: We retrospectively identified all pediatric and young adult patients (0-22 years) at Haukeland University Hospital, Norway (1981-2019), through clinical and …

The Norwegian Childhood Cancer Biobank

Johanne Uthus Hermansen, Dorota Malgorzata Wojcik, Nina Robinson, Jens Pahnke et autres

Introduction: The rapidly expanding era of “omics” research is highly dependent on the availability of quality-proven biological material, especially for rare conditions such as pediatric malignancies. Professional biobanks provide such material, focusing on standardized collection and handling procedures, distinctive quality measurements, traceability …

Case report: Seropositive myasthenia gravis complicated by limbic encephalitis positive for antibodies to AMPAR and Lgi1

Magne Solberg Nes, Mette Haugen, Hans Kristian Haugland, Nils Erik Gilhus et autres

Objectives: Autoantibodies to the α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor (AMPAR) and leucine-rich glioma-inactivated 1 (Lgi1) are associated with autoimmune encephalitis. We described an acetylcholine receptor (AChR)-positive patient with myasthenia gravis who developed limbic encephalitis with antibodies to AMPAR and Lgi1. Methods: A single-case report …

Triaging HPV-Positive Cervical Samples with p16 and Ki-67 Dual Stained Cytology within an Organized Screening Program—A Prospective Observational Study from Western Norway

Irene Tveiterås Øvestad, Ingvild Dalen, Marie Songstad Andersland, Olav Karsten Vintermyr et autres

The implementation of high-risk human papillomavirus testing (hrHPV testing) as a screening method in substitute for cytology has evoked the need for more sensitive and less objective tests for the triage of HPV-positive women. In a cohort of 1763 HPV-positive women, the …

Clinical Characteristics and Histopathology in Suspected Necrotizing Soft Tissue Infections

Ingunn Margareetta Gundersen, Ellen Berget, Hans Kristian Haugland, Trond Bruun et autres

Abstract Background Necrotizing soft tissue infections (NSTIs) are severe diseases with high morbidity and mortality. The diagnosis is challenging. Several guidelines recommend tissue biopsies as an adjunct diagnostic in routine management, but neither biopsy sampling nor classification is standardized or validated. We …
