Cluster headache is a rare, very severe disorder that is clinically well characterized with a relatively poorly understood pathophysiology. Alterations of the hypothalamic-pituitary axis due to chronobiological changes, such as typical temporal pattern of both cluster periods and attacks, point to a
Cluster headache is a rare very severe disorder that is clinically well characterized with a relatively poorly understood pathophysiology. Although peripheral structures are postulated to be involved in triggering the pain attacks, chronobiological changes like the cluster period and the complex
Alpha-N-acetyl-beta-endorphin (Ac-beta-EP) is a post-translational product of beta-endorphin (beta-EP) with no analgesic properties. Ac beta-EP is present in human fetal and adult pituitary gland and cross-reacts in all available beta-EP assays. This study evaluates levels of Ac-beta-EP in the
Varying reactions of the vegetative nerve system to various point combinations (for example: vomiting, dizziness, diarrhea, urge to urinate, fatigue or drowsiness, headache), especially to the needling of Tai Chong (Li 3), induced us to perform biochemical studies before and after acupuncture
Lumbar punctures were performed on four occasions over a 5-day period (8:30 a.m. on days 1, 3, and 5; 2:30 p.m. on day 2) on 10 normal volunteers (five of each sex; mean age, 27.7 years) to assess, with repeated sampling, the day-to-day variation of selected CSF parameters. Two subjects abstained
Adrenal ganglioneuromas are rare tumors originating from the neural crest tissue of the sympathetic nervous system. The clinical presentation for most patients is asymptomatic, and most of these tumors are hormone silent. We report a case of dopamine-secreting adrenal ganglioneuroma associated with
The concentration of 5-hydroxyindoleacetic acid (5-HIAA), homovanillic acid (HVA), kallikrein-like enzymes and beta-glucuronidase were quantified in the cerebrospinal fluid (CSF) during spontaneous migraine attacks. Plasma levels of kallikrein-like enzymes and beta-glucuronidase, as well as urinary
To investigate the role of central neurotransmitters in the pathogenesis of migraine, we measured cerebrospinal fluid (CSF) levels of certain amino acids (glycine, taurine, glutamine) and metabolites of biogenic amines (5-hydroxyindoleacetic acid and homovanillic acid) in 38 migraine patients and
A 5-year-old boy presented with headache and hypertension. Screening abdominal ultrasonography showed a 6-cm-sized mass in the left adrenal gland. Laboratory data included urine vanillylmandelic acid/creatinine (208.3 microg/mg), urine homovanillic acid/creatinine (114.3 microg/mg), serum
