Synovial Chondromatosis of the Metacarpophalangeal Joint

Journal of Hand Surgery, 2002
We describe a case of synovial chondromatosis in a metacarpophalangeal joint with invasion of local structures. The degree of local tissue involvement was not demonstrated on the preoperative MRI scans. This case highlights that synovial chondromatosis can be invasive and that even the best preoperative imaging may not demonstrate this.

Enhancing Sensitivity across Scales with Highly Sensitive Hall Effect‐Based Auxetic Tactile Sensors

Advanced Intelligent Systems, Volume 7, Issue 3, March 2025.
Herein, a tactile sensor based on hall‐effect sensors with an auxetic structure, called Hall effect‐based auxetic tactile sensor (HEATS), is proposed. The change in magnetism resulting from the deformation of the auxetic structure is utilized for sensing.

The Relationship between Rest Tremor and Underlying Lewy Pathology in Essential Tremor: A Clinical‐Pathological Study of 201 Cases

Annals of Neurology, EarlyView.
Objectives Prospective studies demonstrated that essential tremor is a risk factor for Parkinson's disease. Identifying clinical markers for conversion from essential tremor to essential tremor‐Parkinson's disease would be of considerable value. Rest tremor can be present in advanced essential tremor and may be a harbinger of conversion. We examined (1)
