Varicella zoster infection-associated progressive encephalomyelitis with rigidity and myoclonus in a 6-month follow-up.
BMJ Case Rep
December 2024
Internal Medicine, Hirslanden Klinik Sankt Anna, Luzern, Switzerland
A patient with reactivated varicella zoster virus (VZV) manifesting in the left-sided dermatome L3 and S2-S4 developed tonic spasms which morphed into myoclonic jerks, paresis, rigidity and hypoesthesia of the left leg. Later, stimuli-sensitive myoclonus progressed to affect the upper body and was accompanied by fever surges with high-frequency myoclonus, hypertensive derailment, dysphagia and other features of the brainstem with autonomic dysfunction. Cerebrospinal fluid tested positive for VZV, MRI showed no signs of myelitis and EEG was negative for epilepsy.

Shins are one of the most vulnerable bones in human body. Shin guards are evaluated by their effectiveness in reducing the force applied to the bone. In this study, a structural modified mechanical lumped model of the shin guard was developed to provide maximum force distribution using physical parameter change modification technique and genetic algorithm.

Thoracic injuries, most frequently rib fractures, commonly occur in motor vehicle crashes. With an increased reliance on human body models (HBMs) for injury prediction in various crash scenarios, all thoracic tissues and structures require more comprehensive evaluation for improvement of HBMs. The objective of this study was to quantify the contribution of costal cartilage to whole rib bending properties in physical experiments.

Am J Physiol Regul Integr Comp Physiol

Department of Biomedical Engineering, Toyo University, Saitama, Japan.
A previous study reported an increase in carotid-femoral pulse wave velocity (cfPWV) during an upright posture compared to the supine position, partly due to sympathetic activation. However, given that cfPWV is influenced by the transmural pressure (TMP) of the artery, which is elevated in the abdominal aorta in the seated posture due to increased hydrostatic pressure. Thus, it remains unclear whether this increased cfPWV reflects a true rise in arterial stiffness or is simply a result of the elevated TMP.

Introduction: Clinically, knowing whether a static stretching (SS) intervention program conducted for several weeks can reduce passive muscle stiffness is important. Still, only a few previous studies have evaluated the chronic effects of an SS intervention program in older adults, and the potential relationship between ROM changes and muscle stiffness changes is still unclear. This study aimed to investigate the effects of a 10- week SS intervention partially supervised program on joint range of motion (ROM) and tissue hardness in older adults.
