Herpes zoster myelitis: nervous system complications.

Transverse myelitis after a zoster viral infection is an exceptional occurrence. In this case we documented an antibody activity against varicella zoster (V-Z) in the cerebrospinal fluid in association with Coxsackie A enterovirus. The clinical course was atypical because of a second episode of myelitis 2 years after the first episode of neurologic viral complications. The positive outcome of therapy with Acyclovir is noteworthy. This case was retrieved in a review of neurologic complications observed in the last few years in patient affected by zoster in our hospital.

Calcium entry blocker: treatment in acute pain in cluster headache patients.

15 chronic cluster headache patients in whom pain was induced by nitroglycerin received acute intravenous treatment with a calcium entry blocker. At the time of peak pain we noted a sudden decrease after the Verapamil injection. The mechanism by which the calcium entry blocker afforded relief is unlikely to have been vasodilatation in patients whose blood vessels had just been dilated by nitroglycerin. A more probable mechanism is blockade of the release of the pain-inducing neurotransmitters. The vasodilatation phase is not a primary factor in the onset of pain.

Cryptococcal meningoencephalitis. Case report and review of Italian literature.

A case of cryptococcal meningoencephalitis, as presented by a hypertensive hydrocephalus, is described. To our knowledge, this is the 24th case described in Italy since 1953. The diagnosis was made with ventricular fluid examination: the patient was successfully treated with amphotericin B and 5-fluorocytosine, thus avoiding the risks of surgical treatment of hydrocephalus. Early diagnosis and proper therapy are necessary in order to decrease the high lethality of cryptococcosis.

Clinical usefulness of a dopaminergic agonist in headache diagnosis.

The dopaminergic system seems to be involved in pain modulation. In a 1983 publication, the administration of a dopaminergic agonist has been proposed as a test able to distinguish migraine from other cephalalgia. In the present study, 123 people were tested, 102 of them being migraine patients and the others being normal subjects. The test showed highly specificity for headache patients when compared to normal subjects, and was highly specific for migraine patients when compared to headache patients. Data are discussed considering the clinical diagnostic value, pathophysiological and therapeutic aspects.

Naloxone in cerebral ischemia: preliminary data.

The effect of the opiate antagonist naloxone was evaluated in 11 unselected patients with cerebral ischemia. Naloxone reversed neurological deficits in the 4 patients with less evident signs of vascular damage.

Divry-Van Bogaert syndrome. Clinical and ultrastructural findings.

A case of a progressive disease with epilepsy, marble skin, and roentgenographic evidence of tapering of the distal carotid branches with corticomeningeal angiomatosis was studied. The clinical course, angiographic findings, and skin biopsy results justified the diagnosis of noncalcifying venous capillary angiomatosis, or Divry-Van Bogaert syndrome.

Platelet met-enkephalin immunoreactivity and 5-hydroxytryptamine concentrations in migraine patients: effects of 5-hydroxytryptophan, amitriptyline and chlorimipramine treatment.

In thirty patients with common migraine the platelet concentrations of met-enkephalin immunoreactivity (ME) (76 +/- 9 pg/mg protein) were similar to those in 23 healthy volunteers (77 +/- 5), suggesting that there is no alteration in the ME pool in this biochemical compartment in migraine. Chronic treatment (4 weeks) with drugs that interfere with 5-hydroxytryptamine (5-HT) synthesis or uptake induced the expected changes in platelet 5-HT levels, i.e. a rise following administration of the 5-HT precursor 5-hydroxytryptophan (daily dose: 300-500 mg, n = 9) and a decrease after amine uptake inhibition by amitryptyline (30-75 mg, n = 7) and even more by chlorimipramine (30-50 mg, n = 9). Platelet ME concentrations rose by up to approximately 90% over the basal values after either 5-hydroxytryptophan (significantly from week 2) or amitriptyline (at week 2) and were unchanged after chlorimipramine, indicating that 5-HT and ME concentrations in platelets can vary independently. The high platelet ME levels following 5-hydroxytryptophan and amitriptyline cannot be explained at present. They might be due either to increased ME synthesis, possibly in the megakaryocyte, or to decreased utilization by platelets or both.

Complicated migraine in AS hemoglobinopathy.

Neurological manifestations have been rarely described in sickle cell trait carriers. Almost all the patients up to now reported are black and young of age. An adult white man is reported, with AS hemoglobinopathy, affected by complicated migraine, who developed acute occlusion of two middle cerebral artery branches, with persistent neurological deficit. The possible significance of this association is discussed.

Diffuse arachnoiditis following epidural analgesia.

Four cases of spinal arachnoiditis are reported, which occurred as a delayed complication of epidural anaesthesia. Different causes are considered: the most convincing hypothesis is that there was a subarachnoid hyperergic reaction to the drugs injected during epidural anaesthesia.

Course of chronic cluster headache.

A follow-up study (3.2 years) of 56 patients with chronic cluster headache who had had no remissions for at least a year. They were treated with lithium carbonate, methysergide and prednisone singly and in combination. An assessment of the therapeutic benefits is followed by a discussion on the course of chronic cluster headache.

Long-acting ergot: clinical and neuroendocrinological aspects in migraine patients.

The possible interaction between long-acting ergot and the opiate system has been studied in 12 migraine patients, evaluating the PRL releasing effect of morphine. Our data suggest the integrity of the opiate system in migraine patients and demonstrate that long-acting ergot does not interact with the dopaminergic system. We hypothesize that the effect of ergot on migraine pain may be related to the interaction with non-opiate substances with central analgesic action. Chronic treatment with long-acting ergot significantly reduces the peak of pain intensity of the migraine attack.
