Persistence and Recurrence of Primary Hyperparathyroidism.
Best Pract Res Clin Endocrinol Metab
March 2025
Division of Endocrinology and Metabolism, McMaster University, Hamilton, ON, Canada. Electronic address:
Persistent and recurrent primary hyperparathyroidism (PHPT) represent significant challenges in the management of PHPT. Persistent PHPT is defined as persistence of hypercalcemia following parathyroidectomy (PTX) or the recurrence of hypercalcemia within the first 6 months following surgery. Recurrent PHPT is defined as recurrence of hypercalcemia after 6 months following PTX and requires normalization of serum calcium prior to the recurrence.

Primary cutaneous/subcutaneous Ewings sarcoma.
Bull Cancer

Pediatric Oncology, insitut Gustave-Roussy, Villejuif, France. Electronic address:
Amongst Ewing sarcoma family of tumours, (EFST), cutaneous/subcutaneous Ewing sarcoma are defined as tumours arising from cutaneous or subcutaneous tissue, not invading the underlying aponeurosis. They are rare tumours, with less than 200 patients published. They are typically small tumours (less than 5cm), and can arise at any anatomical location, with a particular tropism for distal, truncal and head/neck locations, compared to classical Ewing sarcoma.

Clinical Trials Center, Cardiovascular Research Foundation, New York, New York, USA; Division of Cardiology, Department of Medicine, Columbia University Medical Center/NewYork-Presbyterian Hospital, New York, New York, USA.
Background: Severe calcification is the morphology most strongly associated with stent underexpansion.
Objectives: The aim of this study was to revise an optical coherence tomography (OCT)-derived calcium score to predict stent underexpansion in severely calcified lesions (angle >270°) using a point-based system.
Methods: A retrospective observational study was conducted in which 250 de novo lesions undergoing OCT-guided stenting, with angiographically visible calcium and optical coherence tomographic maximum superficial calcium angle >270°, not subjected to atherectomy or specialty balloon treatment before stent implantation, were randomly divided into derivation (n = 167) and validation (n = 83) cohorts.
Global Algorithm for the Endovascular Treatment of Chronic Femoropopliteal Lesions: An Interdisciplinary Expert Opinion Statement.
JACC Cardiovasc Interv
March 2025
Department of Cardiology and Vascular Medicine, West German Heart and Vascular Center, University of Duisburg-Essen, Essen, Germany.
A global treatment algorithm was developed for the endovascular revascularization of femoropopliteal lesions and chronic total occlusions, aiming toward a more standardized approach to endovascular treatment in patients with peripheral artery disease. The following steps are proposed. 1) Evaluation of lesion morphology based on preprocedural imaging by Duplex sonography and intravenous ultrasound for selection of lesion preparation tools.
