Postural orthostatic tachycardia is a syndrome characterized by an elevated heart rate in response to standing. This syndrome typically presents in late adolescence and early adulthood, with a higher percentage occurring in females. This syndrome is often seen following a viral infection, pregnancy, surgery, or intense psychological stress. This condition presents a wide range of symptoms that vary depending on its unclear etiology. We present the case of a 21-year-old woman with convulsions associated with postural orthostatic tachycardia syndrome after being misdiagnosed with a psychiatric condition for many years.

Purpose: Worsening sagittal alignment of the spine, particularly kyphosis, may cause difficulty in assuming a supine position, restricting sleeping posture and movement and potentially leading to sleep disturbances. However, no studies have explored the relationship between sagittal spinal alignment and sleep disturbance. This study aimed to clarify the relationship between sagittal spinal alignment and sleep disturbance.

Purpose: This study aims to evaluate a new method for the five times sit to stand test (FTSST), crucial for addressing frailty in an aging population. It utilizes a smart insole for plantar pressure analysis and a marker-less motion capture device for head height analysis.
Materials And Methods: Thirty-five participants aged 50 years or older underwent FTSST assessment using three methods: manual measurement with a stopwatch (FTSST-M), plantar pressure analysis with smart insoles (FTSST-P), and head height analysis with a marker-less motion capture device (FTSST-H).

Introduction SARS-CoV-2 infection (COVID-19) and the COVID-19 vaccine have been linked to the development of persistent symptoms, including orthostatic intolerance (OI) and postural orthostatic tachycardia syndrome (POTS), in both children and adults. POTS is characterized by excessive tachycardia and other symptoms upon standing, significantly impacting quality of life. This study aims to evaluate the clinical and laboratory findings in pediatric patients with post-COVID-19 or post-COVID-19 vaccine OI and POTS.

Since its first description more than a decade ago, our understanding of the clinical impact of hereditary alpha-tryptasemia has continued to evolve. First considered to be a genetic disorder with a subset of patients having a syndromic presentation composed of connective tissue abnormalities, symptoms of autonomic dysfunction, and findings of mast cell activation, we now know that hereditary alpha-tryptasemia is a common genetic trait and modifier of mast cell-mediated reactions. More recent studies have shown some previously held associations with congenital hypermobility and postural orthostatic tachycardia syndrome (POTS) to be lacking, and illuminated previously unappreciated associations with clonal and nonclonal mast cell disorders.
