The case illustrates the possible link between coronary spasms, intraluminal thrombus formation, and widespread organized and layered thrombi in HTx patients. Furthermore, the case underlines the clinical value of OCT as a novel method for high-resolution vessel imaging in heart-transplanted (HTx) patients with coronary spasms and suspected coronary artery disease. Coronary spasms and sudden de...

A radioimmunoassay is described for plasma corticotropin whereby concentrationsover the range of 6 to 1000 ng/liter can be measured. Corticotropin extracted from plasma on fuller’s earth under carefully standardized conditions is assayed by a long-used double antibody radioimmunoassay procedure. Within (n = 6) and between (n = 12) assay precision is 39 ± 2 (SD) ng/liter and 44 ± 6 (SD) ng/liter...

Involuntary contractions of paralyzed muscles (spasms) commonly disrupt daily activities and rehabilitation after human spinal cord injury (SCI). Our aim was to examine the recruitment, firing rate modulation, and derecruitment of motor units that underlie spasms of thenar muscles after cervical SCI. Intramuscular electromyographic activity (EMG), surface EMG, and force were recorded during the...

In the days before widespread internet use, iPhones, and iPads, the American Board of Psychiatry and Neurology part II oral board examination provided a unique opportunity for examiners to meet, mingle, and network. Sometimes interesting collaborations developed. Such was the case in 1994 when we had the same hour off on Dr. Alan Percy’s child neurology team. We were discussing infantile spasms...

Down syndrome (DS) is the most common genetic cause of mental retardation. It is estimated that 5-13% of persons affected by DS have seizures. Infantile spasms are the most common type of seizures and usually are well controlled with steroids and antiepileptic drugs. We present 11 children at the age of 3 years and 4 months to 10 years and 7 months with DS and infantile spasms, treated at Child...

Amphetamine use is associated with dysphoric states, including heightened anxiety, that emerge within 24h of withdrawal from the drug. Corticotropin-releasing factor increases serotonin release in the central nucleus of the amygdala, and this neurochemical circuitry may play a role in mediating fear and anxiety states. We have previously shown that chronic amphetamine treatment increases cortic...

The effects of glycyrrhizin on the pituithry adrenal axis were studied. Isolated rat anterior pituitary glands were incubated with 14C-phenylalanine and biosynthetic activity of corticotropin in the pituitary was estimated. The rate of incorporation of radioactivity from 14C-phenylalanine into corticotropin fraction in the rat anterior pituitary was increased specifically by prior adrenalectomy...

Adrenergic receptors modulate motoneuron excitability, sensory synaptic 1 transmission and muscle spasms after chronic spinal cord injury. 2 Rank MM, Murray KC, Stephens MJ, D’Amico J, Gorassini MA, and Bennett DJ 3 Centre for Neuroscience, University of Alberta, Edmonton, Alberta, Canada 4 5 6 Running Title: Adrenergic receptors modulate spasms. 7

Infantile spasms represent a seizure disorder with unique clinical and electroencephalographic (hypsarrhythmia) features and a poor prognosis including chronic intractable epilepsy and psychomotor retardation. The association of spasms and hypsarrhythmia, with or without mental retardation, defines West's syndrome. West's syndrome is not uncommon; the incidence is considered to be 0 16-0-42 per...

BACKGROUND Cancer-related bladder spasms may be a rare but severe symptom of bladder or metastatic cancer or its related treatments. Various treatments described in the literature include systemic medications, intravesical or epidural medications, or even sacral neurolectomies. OBJECTIVE We present 3 patients who have suffered from bladder spasm either from invasion of the bladder wall by tum...
