Kuru was diagnosed in a 42-year-old Melanesian male from the Eastern Highlands Province of Papua New Guinea. The clinical features indicated predominant cerebellar degeneration together with widespread cortical neuronal dysfunction and involvement of the diencephalon, hippocampus and basal ganglia. Dementia was an early and prominent feature. The duration of clinical illness was about 12 months and atypically he spent the last 7 months in hospital allowing continuous assessment. At autopsy, spongiform encephalopathy was demonstrated, and inoculation of brain tissue into 4 squirrel monkeys and 1 capuchin monkey resulted in the development of kuru. This is the longest continuous study of kuru in a hospital setting to be recorded in the adult human subject. The virus isolated from the brain of this patient has been adopted as a standard reference strain of kuru for future use and repository.

Comparison of Bicortical Headless Cannulated Screw Fixations, Tension Band Fixations, and Kirschner Wire Fixations of a Jones Fracture: A Biomechanical Study.
J Am Podiatr Med Assoc
January 2025
‡Canakkale Onsekiz Mart University Medical Faculty, Department of Orthopedics and Traumatology, Çanakkale, Turkey.
Background: The aim of study was to biomechanically compare the fixation of Jones fracture using headless cannulated screw, tension band, and two Kirschner wires.
Methods: A total of 60 fourth-generation, fifth metatarsal synthetic bone models were divided into three groups according to the fixation techniques. A vertical load, oriented from plantar to dorsal and lateral to medial, was applied to the metatarsal specimen that were potted with molding material.

Article Synopsis
- The study investigated how core muscle endurance relates to the functional abilities of extremities in women with fibromyalgia.
- The research included 57 women and used various assessments like pain scales and endurance tests to collect data on their physical capabilities.
- Findings indicated that core endurance showed weak to moderate correlations with functional tasks and pain levels, suggesting that improving core strength could positively influence overall function in these patients.

Background: Prenatal exposure to high levels of testosterone affects the development of the brain. The purpose of this study was to compare the mothers of children with attention deficit hyperactivity disorder (ADHD) and those of healthy children in terms of the digit ratio (2D:4D). It also examines the relationship between ADHD symptoms and the 2D:4D in mothers.

Objective: Hysteroscopic myomectomy is widely regarded as safe and feasible, although achieving single-session results for larger myomas often requires alternative methods. This study introduces a novel approach: ultrasound-guided myoma extirpation using ring forceps combined with hysteroscopy.
Methods: This retrospective, single-center study includes patients who underwent ultrasound-guided myoma extirpation between 2016 and 2024.
Feasibility of on-site CT-FFR analysis on cardiac photon-counting CT in evaluation of hemodynamically significant stenosis in comparison to invasive catheter angiography.
Eur J Radiol

Department of Radiology and Nuclear Medicine, University Medical Center Mannheim, Heidelberg University, Theodor-Kutzer-Ufer 1-3, 68167 Mannheim, Germany. Electronic address:
Objectives: Coronary CT angiography (CCTA) is an excellent tool in ruling out coronary artery disease (CAD) but tends to overestimate especially highly calcified plaques. To reduce diagnostic invasive catheter angiographies (ICA), current guidelines recommend CT-FFR to determine the hemodynamic significance of coronary artery stenosis. Photon-Counting Detector CT (PCCT) revolutionized CCTA and may improve CT-FFR analysis in guiding patients.
