Data from a dynamic simulation in a free-floating and continuous regime of a solar greenhouse modelled in TRNSYS 17 considering simultaneously different thermal phenomena.

This dataset supports the research article "Complete greenhouse dynamic simulation tool to assess the crop thermal well-being and energy needs" [1]. In the agricultural sector, the use of energy can be very intensive [2] and the simulation of solar greenhouses is a very complex work [3]. This dataset provides the results of thermal modeling and dynamic simulation of a solar greenhouse considering simultaneously several thermal phenomena.

Acetazolamide efficacy and tolerability in migraine with aura: a pilot study.

The study was an open uncontrolled pilot trial to test the efficacy and the tolerability of acetazolamide in a group of 22 outpatients suffering from migraine with aura (MA) with at least one aura episode in the last 2 months.

Trigeminal stimulation elicits a peripheral vestibular imbalance in migraine patients.

Objective: The study explored the hypothesis that spontaneous nystagmus (Ny) in migraine patients can be triggered or modulated by painful trigeminal stimulation, providing evidence of a functional connection between vestibular and trigeminal systems.

Background: Vertigo attacks are reported by subjects with migraine or a familiar history of migraine, also independently of headache episodes. Idiopathic vertigo is three times more frequent in migraine patients than in controls.

Long-term outcome of migraine therapy: predictive value of the frontotemporal nitroglycerin test.

We evaluated whether type of response to the migraine-induction test with a nitroglycerin ointment applied to the frontotemporal head region could predict the efficacy of antimigraine therapy. Forty-two patients with migraine without aura underwent the test before and 2 months after antimigraine therapy. Two and 4 months after treatment withdrawal, most subjects with a negative response to the post-treatment test maintained treatment benefit, whereas benefit was lost in patients with an early onset migraine response.

The frontotemporal region plays a role in the genesis of migraine without aura.

We have compared the migraine-inducing effect of nitroglycerin ointment applied to the frontotemporal region of the head, which is innervated by the ophthalmic and maxillary divisions of the trigeminal nerve, with that of nitroglycerin applied to the chin (innervated by the mandibular division), the posterolateral region of the neck (innervated by the second and third cervical roots), the lateral surface of the proximal third of the forearm (innervated by the sixth cervical root), and the medial surface of the upper-arm region (second dorsal root). One hundred patients suffering from migraine without aura were randomly divided into five equal groups. Each group received an application of 5 mg nitroglycerin in 2% ointment on a preselected body area for 2 hours.

The antimigraine effect of ergotamine: a role for alpha-adrenergic blockade?

The hypothesis that alpha-adrenergic receptor blockade accounts for the ability of ergotamine to stop migraine attacks was tested, in migraine patients, in an experimental migraine model based on nitroderivative- induced attacks. In a preliminary single blind, placebo controlled study, thymoxamine, a prevalently post-synaptic alpha adrenergic receptor antagonist, was able to abort migraine attack in 9 out of 10 patients, as opposed to 2 out of 10 by placebo (p < 0.005 Fisher's exact test).

[Possible mechanisms of the action of drugs for hemicrania].

Different classes of drugs are used in the pharmacological treatment of headache, both during migraine crisis and migraine prophylaxis. How these drugs exert their therapeutical effect in migraine is not clearly understood. Hypothetical mechanisms of action are discussed by the Authors in regard to the different pathogenetical events relevant to migraine.

Source of pain and primitive dysfunction in migraine: an identical site?

Twenty common migraine patients received a one sided frontotemporal application of nitroglycerin (10 patients) or placebo ointment (10 patients) in a double blind study. Early onset migraine attacks were induced by nitroglycerin in seven out of 10 patients versus no patient in the placebo group. Subsequently 20 migraine patients, who developed an early onset attack with frontotemporal nitroglycerin, received the drug in a second induction test at other body areas.

A case of Dejerine-Sottas disease with prominent ataxia and brain stem involvement. A clinical, electrophysiological, otoneurologic, and ultrastructural study.

A case is presented of Dejerine-Sottas disease in a 12-year-old boy in which clinical signs made diagnosis of Friedreich's ataxia seem plausible. Based on marked slowing of motor conduction velocity, the sural nerve biopsy findings of a hypertrophic neuropathy with hypo- and demyelination of the nerve fibres, as well as the clinical history, the diagnosis of Dejerine-Sottas disease was made. ABR examination suggested involvement of brain stem at the roots and/or nuclei of the eighth cranial nerve, without involvement of higher structures.

The effect of bromocriptine on plasma catecholamine concentrations in normal volunteers.

The effect of the ergot derivative bromocriptine (5 mg orally) on blood pressure and plasma catecholamine concentrations was explored in normal volunteers. A significant decrease of plasma noradrenaline was found, while dopamine and adrenaline concentrations did not change significantly. Systolic and diastolic blood pressures were significantly lowered at 150 min after administration.

Timed-release dihydroergotamine in the prophylaxis of mixed headache. A study versus amitriptyline.

A pharmacological trial has been carried out on 41 out-patients suffering from mixed headache. The prophylactic effect of a timed-release dihydroergotamine formulation was tested versus amitriptyline. Patients reported daily, on appropriate cards, the hours of headache and the degree of pain during the month before therapy and on the following two months of treatment.

Headache patients: different responses induced by naloxone during work-test.

The responses to work-test in ischemia (tourniquet technique), before and after I.V. injection of naloxone (2 mg) or saline, were investigated in healthy volunteers and patients suffering from various types of headache.
