Epiphyseal chondrodysplasia, Miura type (ECDM) is a skeletal dysplasia with tall stature and distinctive skeletal features caused by heterozygous NPR2 pathogenic variants. Only four families have been reported. We present a family with five affected individuals (mother, three sons, and daughter). The mother's phenotype was relatively mild: borderline tall stature and elongated halluces operated during childhood. The children were remarkably more severely affected with tall stature, scoliosis, and elongated toes and fingers leading to suspicion of Marfan syndrome...

Pyoderma gangrenosum (PG) is a rare noninfectious skin condition which clinical picture can overlap with that of the diabetic foot. Meticulous physical examination along with biopsy and magnetic resonance imaging (MRI) can make the distinction easier, saving the patients from undergoing a debilitating intervention. We report a case of pathologically proven PG in the right ankle region of a 55-year old male with known uncontrolled diabetes mellitus and inflammatory bowel disease. Radiographs revealed increased soft tissue density overlying the lateral melleolus of the right ankle...

Ankles can benefit from the elastic tube bandage (ETB) by providing the ankle joint with compression, but partial high- or low-pressure leads to body discomfort. The aim of this paper is to propose a method for analyzing the ankle shape with the fabric compression which is basis on the comfortable pressure on human body. First, a standard model of ankle is established from the scanned data of 306 samples, and the mapping of the fabric shape curves on ankle were constructed by the U-direction convex curves of the model...

Patients with obstructive sleep apnea (OSA) are susceptible to developing atherosclerosis. Consequently, such patients are at a high risk of developing cardiovascular diseases, leading to poor prognosis. Many physiological parameters have been previously used to predict the development of atherosclerosis. One such parameter, the cardio-ankle vascular index (CAVI), a measure of arterial stiffness, has garnered much attention as it can also predict the degree of atherosclerosis. The CAVI can be calculated based on noninvasive measurements, and is less susceptible to blood pressure variations at the time of measurement...

Neural feedback plays a key role in maintaining locomotor stability in the face of perturbations. In this study, we systematically identified properties of neural feedback that contribute to stabilizing human walking by examining how the nervous system responds to small kinematic deviations away from the desired gait pattern. We collected data from 20 participants (9 men and 11 women). We simultaneously applied (1) small continuous mechanical perturbations, forces at the ankles that affected foot placement, and (2) small continuous sensory perturbations, movement of a virtual visual scene that produced the illusion of change in walking speed, to compare how neural feedback responds to actual and illusory kinematic deviations...

BACKGROUND AND OBJECTIVE: Detectors of ankle-brachial index (ABI) are commonly used in cardiovascular patients who have high-risk levels of arteriosclerosis. Increased evidences suggest that patients with arteriosclerosis possess many risks of geriatric and chronic diseases. Meanwhile, new chronic treatments trend from the hospitals toward family and community health centers, but for arteriosclerosis cases have delivered benefits far below instrument costs. Compared to traditional devices based on cuff pressure, cuffless and non-invasive measures have wider application potential in home health care, especially in the case of physically-restricted or severely symptomatic patients...

INTRODUCTION: Cerebral small-vessel disease (CSVD) is an extensive cerebrovascular disease associated with many poor outcomes. Previous studies have shown that brachial-ankle pulse wave velocity (baPWV) is related to various neuroimaging signatures, but its association with the total CSVD burden remains unknown. We aimed to explore whether baPWV is related to the total CSVD score and to establish a cutoff for detecting the presence and severity of CSVD, which may guide clinical preventive measures...
