Pediatric Multiple Sclerosis Presenting as Area Postrema Syndrome.
A 10 year-old girl with no significant past medical history developed acutely incoercible nausea and vomiting. One week later she complained about double vision and instability. She had no previous history of other neurological symptoms, preceding illness or fever. Her examination was consistent with multidirectional nystagmus, marked dysmetria of the upper and lower extremities and incapacitat...
متن کاملMelatonin modulates baroreflex control via area postrema
Pineal gland and its hormone melatonin have been implicated in modulation of cardiovascular system. We aimed at studying the effects of melatonin on baroreflex sensitivity and the role of area postrema, as a component modulator of baroreflex arch. Mean arterial pressure (MAP) and heart rate (HR) were recorded in conscious freely moving rats. Baroreceptor reflex sensitivity was assessed by deter...
متن کاملNeurenteric Cyst of the Area Postrema
Neurenteric cysts are CNS lesions most frequently occurring in the spinal cord. Intracranial neurenteric cysts are rarer, typically presenting with headache, mass effect, or location-specific symptoms. The area postrema is known as the emetic center of the brain; lesions can cause nausea and vomiting. Our case, featuring a neurenteric cyst of the area postrema, illustrates the importance of con...
متن کاملAMPA receptor activation of area postrema neurons.
This study reports on the effects of activation of ionotropic glutamate receptors on area postrema neuron cytosolic calcium concentration ([Ca2+]i). In 140 of 242 area postrema neurons isolated from postnatal rats, application of 100 μMl-glutamate (l-Glu) resulted in a significant increase in [Ca2+]i. The remaining neurons were unaffected. The effects ofl-Glu on area postrema [Ca2+]iwere dose d...
متن کاملArea postrema neurons are modulated by the adipocyte hormone adiponectin.
Adiponectin is an adipocyte-derived peptide hormone involved in energy homeostasis and the pathogenesis of obesity, including hypertension. Area postrema (AP) lacks a blood-brain barrier and is a critical homeostatic integration center for humoral and neural signals. Here we investigate the role of AP in adiponectin signaling. We show that rat AP expresses AdipoR1 and AdipoR2 adiponectin recept...
