Among many metabolic disorders, porphyrias and Fabry disease are known to affect autonomic nervous system. In patients with acute intermittent porphyria, hereditary coproporphyria, and variegate porphyria, autonomic symptoms such as abdominal pain, vomiting, hypertension and tachycardia are among the most prominent clinical manifestations. Fabry disease is clinically characterized by severe limb pain, hypohidrosis, angiokeratomas and various autonomic symptoms. In both porphyrias and Fabry disease, pathological changes in the central and peripheral autonomic nervous system have been documented. In porphyrias, a loss of myelinated fibers, axonal degeneration, and segmental demyelination in peripheral autonomic nerves as well as chromatolysis of several brain stem nuclei have been found. In Fabry disease, abnormal amount of the substrates of alpha-galactosidase, i.e. ceramide di- and trihexoside, are found to be accumulated in the central and peripheral autonomic nerves.

The occurrence of sleep troubles, recurrent abdominal pain, motion sickness, hyperactivity, dizziness, limb pain, cyclic vomiting, pseudoangine and the headache or migraine family history have been studied in 68 children migraine sufferers and compared to 68 non-headache sufferers whose ages range from 7 to 15. Data have revealed a significant predominance of those symptoms and family histories in migraine sufferers except pseudoangine which has had no significance, sleep troubles significant only in males and limb pains in females. The possibility of considering those factors as migraine risk factors is discussed.

Iohexol containing 180 mg I/ml was used in 80 patients for myelography by lumbar injection. By using an adequate volume, between 10 and 20 ml, satisfactory films were obtained in all cases. Minor adverse effects occurred in 12 patients (15%) and were more frequent in women than men; they were headache (5), nausea (3), vomiting (2), back or limb pain (5), and skin rash (1) and were of minor degree in 10 cases, moderate in the other two and lasted more than 24 h in only one case. There was no change in vital signs or neurological examination related to the studies. No patient suffered difficulty with concentration, personality change or seizures. Electroencephalograms performed on 21 patients before and during the 24 h after iohexol showed no seizure or focal activity or any significant change. Repeat lumbar punctures were performed on ten patients during the 24 h following myelography. One of these, a patient with symptoms due to disc prolapse, whose CSF was abnormal prior to the myelogram, showed a slightly increased cellular response. There was no significant change in any other case. Iohexol is a very satisfactory contrast medium for myelography and compares favourably with other non-ionic contrast media.

Both epidemiological and pharmacoclinical research have been carried out on children suffering from headache. Two epidemiological trials were performed. In the first, 562 migrainous children were questioned about several clinical symptoms that affect child headache suffers, and the incidence of these symptoms was recorded. In the second, we divided 504 nonselected school children into three groups: headache sufferers and nonheadache sufferers with or without family headache history. The same clinical symptoms were studied. Statistical analysis showed that motion sickness, recurrent abdominal pain, sleeping troubles, hyperactivity, cyclic vomiting, dizzines, and limb pain have different incidences in the three groups. These clinical symptoms and family headache history may be considered HR factors and indicate a predisposition to headache in children. The pharmacoclinical study was carried out on 15 migrainous children, five hyperactive and 10 controls. An increased sensitivity of iris adrenergic receptor in both migrainous and hyperactive children was evidenced by measuring phenylephrine-induced mydriasis. The possible etiopathogenetic correlations among headache, hyperactivity, and other HR factors are discussed in accordance with the central theory of headache.

The effectiveness of dihydroergotamine administered by home subcutaneous injection by the patient or family for severe headache attacks was assessed retrospectively in 51 patients. Average follow-up was 21 weeks. Twenty-one patients had intermittent migraine attacks, 27 had transformed migraine with chronic daily headache, and 3 had chronic tension-type headache. Of the 51 patients taught home injection, 35% had an excellent overall response, 18% had a good response, 12% had a poor response but continued to use dihydroergotamine, and 35% had discontinued dihydroergotamine use. Side effects were the main reason for stopping dihydroergotamine. These included nausea or vomiting or both, limb pain or numbness or both, chest or throat tightness or both, and soreness at the injection site. Thirty-three patients (65%) continued to use dihydroergotamine at the end of the follow-up period. In patients who previously required injections from medical personnel for headache crises and in whom home injection of dihydroergotamine was effective, a dramatic reduction occurred in hospital emergency room and physician office utilization. Dihydroergotamine use by home injection can be an effective treatment for a significant proportion of patients with severe migraine including patients with transformed migraine and medication overuse.

Many reports in the literature seem to confirm the hypothesis that the symptoms of periodic syndrome are precursors or the equivalent of migraine: the aim of this study was to assess the prevalence of periodic syndrome in a group of children and adolescents suffering from migraine in comparison with that observed in various control groups. We considered seven symptoms: recurrent vomiting and abdominal pain, migrating limb pain, vertigo, recurrent hyperthermia with no visible cause, sleep disturbances and eating disorders. The study involved 171 children divided into four groups; 42 migraineurs; 37 subjects with chronic nervous pathologies but no psychosomatic symptoms; 46 subjects with a known psychosomatic disease, and 46 healthy subjects. The prevalence of the symptoms in the different control groups was different, although the pattern was more similar in the migraineurs and psychosomatic patients than in the other control groups. The development continuum of the syndrome may support the view that periodic syndrome is predictive of the subsequent development of a psychosomatic pathology.

The aim of the study was to determine the nature, severity, precipitants and associated features of attacks and the incidence of potential aetiological factors of cyclic vomiting syndrome (CVS). Ten patients (6 boys and 4 girls aged 2-12 years) with CVS, defined as recurrent episodes of vomiting with symptom-free intervals occurring two or more times per year, with episodes having a similar pattern and for which no other cause could be found, ten patients (7 boys and 3 girls aged 7-14 years) with migraine, defined as recurrent headache with symptom-free intervals and at least three of the following symptoms or associated findings: abdominal pain, nausea or vomiting, throbbing headache, unilateral location, associated aura (visual, sensory, motor), relief after sleeping and ten controls (6 boys and 4 girls aged 4-13 years) were studied. The mean age at onset of symptoms in patients with CVS was 3.9 years and the mean number of attacks per year was 4, the average duration of episodes was 20.5 hours and the mean number of school missed days were 6 per year. The mean age at onset of symptoms in patients with migraine was 7.6 years and the mean number of attacks per year was 9.9, the average duration of episodes was 8 hours and the mean number of school missed days were 6.4 per year. A family history of migraine was significantly higher in both groups of patients, compared with controls (p = 0.009). A personal history of headache and/or migraine and associated sign or symptoms like recurrent abdominal pains, limb pain and kinetosis was significantly higher in both patients compared with controls (p < 0.001). CVS is a chronic, disabling condition and is a migraine variant, with attacks usually precipitated by stress and intercurrent infections.

Drug challenge test (DCT) is performed to evaluate chronic pain pharmacologically and determine its medical treatment. One test drug is administered in one day for DCT and characterization of the test drug. Four patients developed side effects of the test drugs for DCT in whom other drug tests were postponed or canceled. A 58-year-old man with multiple arthritis of rheumatic arthritis and fibromyalgia had headache, nausea, and vomiting all day after ketamine test. A 76-year-old man with chronic general pain and failed back surgery syndrome had vomiting and abdominal discomfort two hours after morphine test and had redness and itching on his bilateral forearms the following day. A 78-year-old man with chronic lumbar and right lower limb pain due to L 4-5 lumbar disc herniation and postherpetic neuralgia felt dizzy, fell down and bruised on his lower back and left knee twelve hours after morphine test. A 32-year-old woman with chronic pelvic pain had skin eruption on her thigh the day after phentolamine test. Although the amount of the test drug in DCT is small and its half-life is short, long-term side effects might occur. We should decrease the amounts or frequencies of ketamine and morphine, and administer them taking long intervals before other tests.

The purpose of this study was to document the clinical and demographic characteristics of the 20 most frequent users of emergency departments (EDs) in one urban area. We reviewed administrative records from three EDs and two agencies providing services to homeless people in Baltimore City. The top 20 users accounted for 2,079 visits at the three EDs. Their mean age was 48, and median age was 51. Nineteen patients visited at least 2 EDs, 18 were homeless, and 13 had some form of public insurance. The vast majority of visits (86%) were triaged as moderate or high acuity. The five most frequent diagnoses were limb pain (n = 9), lack of housing (n = 6), alteration of consciousness (n = 6), infection with human immunodeficiency virus (HIV) (n = 5), and nausea/vomiting (n = 5). Hypertension, HIV infection, diabetes, substance abuse, and alcohol abuse were the most common chronic illnesses. The most frequent ED users were relatively young, accounted for a high number of visits, used multiple EDs, and often received high triage scores. Homelessness was the most common characteristic of this patient group, suggesting a relationship between this social factor and frequent ED use.
