Unknown primary tumour (UPT) is defined as a histologically confirmed metastatic malignancy for which no primary site has been detected. It accounts for approximately 3-5% of all malignant neoplasms. UPT represents a group of heterogeneous cancers with rapid progression and random, atypical metastases. This article describes the diagnostic strategies, treatment, prognosis and survival of patients with UPT.

Endoscopic ultrasound-guided biopsy of healthy pig pancreas - Towards the histological diagnosis of chronic pancreatitis.
Rev Esp Enferm Dig
September 2024
Gastroenterology, Hospital Clínico Universitario de Santiago.
Background: diagnosis of early chronic pancreatitis (CP) is a challenge due to the lack of accurate methods. The ability of endoscopic ultrasound (EUS) guided biopsy to obtain pancreatic core tissue samples in patients with minimal changes of CP and its potential use for the histological diagnosis of early CP are unknown. The aim of the study was to evaluate the ability of different EUS-guided biopsy core needles to obtain histological samples of healthy pig pancreas.

Introduction: Management of patients with large aortic arch aneurysms who are considered high risk for frozen elephant trunk technique have been challenging, especially when they have a dilated ascending aorta (AA) that precludes total endovascular branched repair (arch BEVAR). A viable option in our armamentarium is wrapping of the AA (AW), and zone 0 Ishimaru TEVAR.
Methods: Retrospective analysis of our aortic database from 2013 to 2024 to select high-risk patients with aortic arch aneurysm that had an AW and TEVAR.
Is Femoral Head to Acetabular Cup Ratio Associated With Dislocation After Total Hip Arthroplasty?

Rothman Orthopaedic Institute, Philadelphia, Pennsylvania, USA.
Background: Dislocation remains a common complication following total hip arthroplasty (THA). Previous literature has shown that the femoral head-to-neck ratio is essential in hip motion, function, and stability. While large femoral heads and dual mobility bearings have been developed to improve stability, it remains unknown if the ratio between femoral head size to acetabular cup size also plays a role in stability.

In the late 1800s, Nikolaus Friedreich first described "degenerative atrophy of the posterior columns of the spinal cord," noting its connection to progressive ataxia, sensory loss, and muscle weakness, now recognized as Friedreich ataxia (FRDA). Renewed interest in the disease in the 1970s and 80s by the Quebec Cooperative Group and by Anita Harding led to the development of clinical diagnostic criteria and insights into associated biochemical abnormalities, although the primary defect remained unknown. In 1988, Susan Chamberlain mapped FRDA's location on chromosome 9.
