Comorbidities in cluster headache and migraine.

The aim of this study was to investigate the most frequent comorbid diseases occurring in patients with cluster headache (CH) and, for comparison, in migraine patients. Over a period of eight years 130 patients with CH and 982 patients with migraine were diagnosed according to ICHD-II criteria. In all patients the presence and type of different diseases were assessed from medical records and coded by the ICD, X revision. Odds ratios (OR) with corresponding 95% confidence intervals (95% CI) were calculated by logistic regression analyses. Comorbid disorders were present in 56.9% patients with CH and in 56.7% migraine patients. Chronic sinusitis (p = 0.001), malignancy (p = 0.012), diabetes mellitus (p = 0.021), glaucoma (p = 0.038), as well as another primary headache disorders were more frequently present in patients with cluster headache (p = 0.001), than in migraine patients. In the multivariate analysis, chronic sinusitis (OR = 7.6, p = 0.001) and diabetes mellitus (OR = 4.2, p = 0.035), adjusted by gender, age and duration of headache, are more frequently associated with CH than with migraine. Comorbid disorders in CH patients were frequent and similar to those noticed in migraine patients, except chronic sinusitis and diabetes mellitus.

[Incompetence of internal jugular vein valve in patients with transient global amnesia].

BACKGROUND/AIM: Transient global amnesia (TGA) could be related to acute ischemic disturbances in mesial parts of temporal lobes, which are important for memory. Incompetence of internal jugular vein (IJV) valve with venous congestion causes venous microthrombosis of hippocampus. The aim of this study was to investigate the frequency of IJV valve incompetence, as well as other hemodynamic and structural properties of cerebral circulation in TGA patients. METHODS: IJV valve competence was investigated in 40 TGA patients and 30 persons of the control group (matched by age and sex), as well as detection of microembolic signals and detection of right to left cardiopulmonal shunt, cerebral vasomotor reactivity and echocardiography by color triplex ultrasonography and transcranial doppler. RESULTS: A significant difference in frequency of IJV valve incompetence was found between the TGA patients and the control persons (55% TGA vs. 30% controls; p < 0.001). We did not find a significant structural (plaques frequency) or hemodynamic (flow velocity, pulsatility index) differences on arteries of the neck and cerebral arteries between the TGA patients and the controls, except for the increased pulsatility index on the basilar artery (40% TGA vs. 16.6% controls; p < 0.01) and decreased vasomotor reactivity in TGA patients (50% TGA vs 26.6% controls;p < 0.001). Microembolic signals were detected very rarely (17.5% TGA patients vs. 13.3% controls; p > 0.05), as well as right to left cardiopulmonal shunt (15% TGA vs. 16.6% controls; p > 0.05), indicating that embolism was not important for pathogenesis of TGA. Transesophageal echocardiography confirmed it, because only one TGA patient had a potent foramen ovale. CONCLUSION: We found a significantly increased frequency of IJV incompetence in the TGA patients, which confirmed the role of vein drainage disturbances in pathogenesis of TGA.

Changes in the retrobulbar arterial circulation after decrease of elevated intraocular pressue in patients with primary open angle glaucoma.

INTRODUCTION: An altered perfusion of the optic nerve head has been proposed as a pathogenic factor in glaucoma. OBJECTIVE: To evaluate changes of haemodynamic parameters in the retrobulbar arterial circulation after a decrease of elevated intraocular pressure (IOP) in patients with primary open angle glaucoma (POAG). METHODS: Twenty-six patients were examined, 14 men and 12 women, 21 up to 50 years old and 5 below, all with previously diagnosed and treated POAG, and all examined at the Eye Clinic, Clinical Centre of Serbia. IOP was measured both with a Goldmann aplanation tonometer and dynamic contour tonometer. Central corneal thickness was measured with ultrasound pachymeter. Imaging of the retrobulbar arterial circulation by colour Doppler was performed at the Neurology Clinic, Clinical Centre of Serbia. It involved measuring of haemodynamic parameters of the ophthalmic artery, central retinal artery, and posterior ciliary arteries. Peak systolic velocity (PSV) and end-diastolic velocity (EDV) were measured, and resistive index (RI) and pulsatility index (PI) were calculated. RESULTS: Haemodynamic arterial parameters PSV and EDV in the ophthalmic and central retinal artery after decrease of IOP were lower, while RI and PI were higher. In the posterior ciliary arteries PSV, EDV and PI were lower, and RI was higher. CONCLUSION: Changes of the retrobulbar arterial circulation after elevated LOP in POAG patients are important for approach and treatment, while the role of vascular factors in the supplement of the optic disc neuroretinal rim could be a key for progression backlash of glaucoma and the radix of neuroprotection.

Perimenstrual headache: migraine without aura or premenstrual syndrome symptom?

BACKGROUND/AIM: Definition of menstrual migraine as a specific clinical entity or, maybe, migraine headache with menstrually related occurring, still remains unresolved question. The aim of this study was to investigate if perimenstrual headache in our patients fulfills diagnostic the International Classification of Headache Disorders (ICHD) criteria for migraine without aura or represents a different type of headache which is the symptom of premenstrual syndrome (PMS). METHODS: The study included 50 women with headache in perimenstrual period in at least two out of three menstrual cycles, during the last year or longer. Two questionnaires, a questionnaire for headache and a questionnaire for PMS, were used. RESULTS: The majority of all the examined women, 29 of them, had migraine and PMS and 9 women had migraine without PMS. Headache in 38 (76.0%) patients fulfilled diagnostic criteria for menstrual migraine, (26 and 12 women had pure menstrual migraine and menstrually related migraine respectively). Intensity of PMS was not different in a groups of women with different types of headache (p = 0.184): a total number of PMS symptoms was 8.2 +/- 4.6 in the group with pure menstrual migraine, 10.8 +/- 3.9 in the group with menstrually related migraine and 10.8 +/- 6.3 in the group with non-migraine headache. CONCLUSION: This study shows that headache, occurring in perimenstrual period, is not always migraine, but could fulfill criteria for tension-type headache, as well. Specific characteristics of perimenstrual headache, which could distinguish it as a symptom of PMS, were not found. Expected relation in time of headache onset and menarche was not confirmed.

Bilateral SUNCT-like headache in a patient with prolactinoma responsive to lamotrigine.

Short-lasting unilateral neuralgiform headache with conjunctival injection and tearing (SUNCT) syndrome is a rare trigeminal autonomic cephalalgia. The cases of SUNCT with attacks that affected both sides simultaneously have only rarely been reported and some of them had underlying pathology. We have reported a case of bilateral SUNCT-like headache secondary to a prolactinoma and responsive to lamotrigine treatment.
