Reflex sympathetic dystrophy syndrome (RSDS) is a painful condition that usually follows regional trauma. We report the case of a 13-year-old girl that was seen for a painful swelling of the right hand associated with palmar hyperhidrosis, which occurred after a trauma to the hand. Bone scan images showed early tissue abnormality, which was more significant on the right hand and wrist, as well as moderate bone uptake on the right side. Nonsteroidal anti-inflammatory drugs and alternating hot and cold baths led to a marked improvement. RSDS occurs following trauma or subsequent to various diseases or drug intake. This syndrome is related to impaired tissue microvasculature under the influence of abnormal sympathetic reflex hyperactivity. Bone scan is the diagnostic procedure of choice in RSDS, but it may be normal. Physiotherapy should be preferred in pediatric cases.

Progressive Increase in Renal Sympathetic Nerve Activity Induced by Cold Exposure.
Hypertension
January 2025
Department of Environmental Health, Life Science and Human Technology, Nara Women's University, Japan.
Background: Exposure to cold environments is linked to cold-induced hypertension due to activated sympathetic nerve activity (SNA) and arterial baroreceptor reflex dysfunction. However, direct measurement of SNA during cold-induced hypertension and changes in baroreflex control of SNA remain unexplored.
Methods: Chronically instrumented rats were exposed to cold temperatures (10 °C) over 4 days after a control period (24 °C), and renal and lumbar sympathetic nerve activities were simultaneously measured during cold-induced hypertension.
Autonomic Reflexes With Epipharyngeal Abrasive Therapy (EAT).

A literature review was conducted of epipharyngeal abrasive therapy (EAT) in the treatment of chronic epipharyngitis, focusing on the mechanism of action by autonomic nerve stimulation. The mechanism of action of EAT in stimulating the immune system has recently become clear. However, the mechanism of action of EAT on the autonomic nervous system remains to be elucidated.

In this article, we review the study by Jin , which examined the role of intestinal glucagon-like peptide-1 (GLP-1) in counterregulatory responses to hypoglycemia in patients with type 1 diabetes mellitus (T1DM). With the global rise of T1DM, there is an increased burden on society and healthcare systems. Due to insulin therapy and islet dysfunction, T1DM patients are highly vulnerable to severe hypoglycemia, a leading cause of mortality.

The distribution of the common acupoints of acupuncture-moxibustion for gastrointestinal diseases conforms to the rule of the segmental homology of somatic afferent nerve-visceral nerve circuit at the spinal cord level. Acupuncture-moxibustion regulates the gastrointestinal function through the nerve-endocrine-immune system, and especially depending on the integrity of the structure and function of nervous system. The somatic afferent nerve-visceral nerve circuit plays an important role in the process of acupuncture and moxibustion for regulating the gastrointestinal function.

Myocardial ischemia causes the production and release of metabolites such as bradykinin, which stimulates cardiac spinal sensory afferents, causing chest pain and an increase in sympathetic activity referred to as the cardiogenic sympathetic afferent reflex. While the brain stem nuclei, such as the nucleus tractus solitarius and rostral ventrolateral medulla, are essential in the cardiogenic sympathetic afferent reflex, the role of other supramedullary nuclei in the cardiogenic sympathetic afferent reflex are not clear. The dorsomedial hypothalamic nucleus (DMH) is involved in cardiovascular sympathetic regulation and plays an important role in the sympathetic response to stressful stimuli.
