[Background - Migraine affects more than 10% of the Hungarian population, causes significant disability and severely affects patients’ generic and condition-specific quality of life. Despite these facts, a significant proportion of patients is not diagnosed and not treated adequately. Headache centres can provide care for only a fraction of all patients. The task of primary care providers would be greatly simplified by a reliable self-administered migraine screening questionnaire. Objective - To develop a short and reliable questionnaire as a migraine screening tool. Methods - Outpatients at the Headache Service, Department of Neurology, Semmelweis University completed a self-administered questionnaire which contained 9 yes/no questions about their headaches’ characteristics. The number of ’yes’ answers (the patients’ total score) was evaluated in connection with the diagnosis based on the International Headache Society criteria. We calculated the sensitivity, specificity, positive and negative predictive value as well as the misclassification rate for each total score value and used these to establish the final cutoff value of the questionnaire. 306 patients (242 females, mean age 39.1±13.3 years) were enrolled. The diagnosis was migraine in 244. Results - Completing the questionnaire did not pose any difficulty for the patients. At a cutoff value of 5 points the questionnaire’s sensitivity was 0.96 and specificity was 0.61. The positive predictive value was 0.91 and the negative predictive value was 0.81. The misclassification rate was 0.11. Discussion - Our results show that the questionnaire may help the diagnosis of migraine. In order to use it in medical practice, its further evaluation is necessary on a large representative sample of the Hungarian population.]

[Natalizumab therapy, 2013]


[Multiple sclerosis (MS) is the most common chronic disease of the central nervous system in young adults. No curative therapy is known. Currently, six drugs are available that can reduce the activity of MS. The first-line drugs can completely reduce the activity of the disease in nearly two-thirds of the patients. In the remainder, who suffer from breakthrough disease, the condition of the patient worsens, and secondline therapies must be used. The second-line drug natalizumab exhibits almost double efficacy of the first-line drugs, but also have less favourable adverse effects. As a severe side-effect for instance, natalizumab carries the risk of the development of progressive multifocal leucoencephalopathy (PML), caused by a polyoma virus, the JC virus. There are three major risk factors for PML: an anti-JCV antibody status, a long duration of natalizumab treatment and prior immunosuppressant therapy. The lowest-risk group (1:14 286) comprises of patients who are anti-JCV antibody-negative, in whom the prior immunosuppressant use and duration of natalizumab therapy do not influence the risk of PML. With no prior immunosuppressant treatment, the incidence of PML increases to 1 in 192 patients after 2 years among those who are anti-JCV antibody-positive. These data may lead the physician to decide to discontinue natalizumab treatment. The half-life of natalizumab is three months; during this time other therapies can not be administered and the patients encounter the rebound effect: as the patients receiving natalizumab therapy displayed a high disease activity before treatment, the rebound effect can lead to relapses. After the termination of natalizumab secondline disease-modifying therapy with fingolimod may be introduce; no PML cases occur in response to fingolimod treatment. In the large majority of patients taking natalizumab who do not develop PML, this drug is highly effective and can prevent the progression of MS. The benefit of therapy and the risk of PML must be considered on an individual basis, with regard to the disease activity, the progression and the MRI activity, before natalizumab therapy is implemented.]

[Maybe it hurts more than you think! - Neonatal pain]

MIKOS Borbála

[Neonatal pain is often undertreated. This is based on the assumption that because of the immature nervous system and the lack of the myelinisation preterm and newborn does not feel pain. It is confirmed by a number of articles that the fetus and neonate can experience and respond to painful events. This publication gives a brief overview of the ontogeny of the pain, short-and long-term postnatal consequences, as well as the perception of the possibility of a particularly frail child population: premature infants and neonates, based on animal and human studies.]

[Single dose irradiation of defined region of rat brain with stereotactic BrainLab system]


[Background and purpose of our study was to develop a precise dose delivery technique for partial brain irradiation of two rats simultaneously. Methods - Using a self-developed frame stereotactic radiotherapy with single doses of 30-90 Gy was delivered to the frontal lobe of 22 animals. Tolerability and reproducibility of the method were evaluated and dosimetric measurements were conducted to verify the treatment plans. 2, 4 and 6 months after the irradiation magnetic resonance imaging (MRI) scans and histopathological examinations were performed to detect late radiation induced biological changes. Results - Immobilization device provided excellent reproducibility and tolerability. Dosimetry revealed good corres - pondence with planned dose distribution, but the measured absorbed dose was 30% lower than the planned dose. During the 6 months follow-up period the procedure related death of subject animals after 30 Gy, 70 Gy and 90 Gy were 0%, 20% and 100% respectively. T2 signal and structural changes on MRI scans found to be dose and time dependent. While 30 Gy caused no detectable structural changes, 70 Gy lead to cystic necrosis in 2 cases after 4 month. Histopathology revealed signs of necrosis on macroscopic examination after 70 Gy in the high dose region involving both frontal lobes, and no obvious microscopic changes in the surrounding area were detectable. Conclusion - Our technique of rat cranial irradiation using human stereotactic system provided high accuracy of single dose delivery for a pair of small animals, resulting in brain injury in the defined area. This method proved to be a reproducible model for preclinical studies on radiation effects.]

To handle the HaNDL syndrome through a case: The syndrome of headache with neurologic deficits and cerebrospinal fluid lymphocytosis


The syndrome of headache with neurologic deficits and cerebrospinal fluid lymphocytosis (HaNDL) is a rare entity. This disease has been related to migrainous headaches. It is a benign, self-limited disorder, which is characterized by fluctuating neurological symptoms and cerebrospinal fluid lymphocytosis. We describe a case of a 47 years old man with acute onset of headache and aphasia. Cerebrospinal fluid analysis revealed a lymphocytic pleocytosis (25 cells/μl, 100% lymphocytes). Electroencephalogram showed moderate slow rhythm in the left hemisphere, with temporoparietal predominance, and without epileptiform activity. His blood tests as well as magnetic resonance imaging (MRI) results were normal. With the diagnosis of HaNDL syndrome the patient was accepted in the Department of Neurology and discharged with full recovery.

Evaluation of anxiety, depression and marital relationships in patients with migraine


Aim - The aim of this study was to evaluate the frequency and characteristics of attacks in patients with migraine, to determine the effects of anxiety or depressive symptoms, and to evaluate the marital relationships of patients with migraine. Method - Thirty patients who were admitted to the neurology outpatient clinic of our hospital between July 2018 and October 2018 and were diagnosed with migraine according to the 2013 International Headache Society (IHS) diagnostic criteria were included in this cross-sectional study. Age, sex, headache frequency and severity, depressive traits, marital satisfaction and anxiety status were examined. We used the Beck Depression Inventory (BDI), State-Trait Anxiety Inventory (STAI), Maudsley Marital Questionnaire (MMQ) and Visual Analogue Scale (VAS) for measuring relevant parameters. Results - The mean severity of migraine pain according to VAS scale was 6.93 ± 1.41 and the mean number of migraine attacks was 4.50 ± 4.24. The mean BDI score of the patients was 12.66 ± 8.98, the mean MMQ-M score was 19.80 ± 12.52, the mean MMQ-S score was 13.20 ± 9.53, the mean STAI-state score was 39.93 ± 10.87 and the mean STAI-trait score was 45.73 ± 8.96. No significant correlation was found between age, number of migraine attacks, migraine duration, migraine headache intensity, and BDI, STAI and MMQ scores (p>0.05). But there was a positive correlation between MMQ-S and scores obtained from the BDI and STAI-state scales (p<0.05). Conclusion - In this study more than half of the migraine patients had mild, moderate or severe depression. A positive correlation was found between sexual dissatisfaction and scale scores of depression and anxiety.

Hyperhomocysteinemia in female migraineurs of childbearing ages


Background and purpose - Migraine is a risk factor for ischemic stroke in women of childbearing ages. Previous researches revealed a higher prevalence of hyperhomocysteinemia in migraineurs. Possible differences on the frequencies of hyperhomocysteinemia between migraine with aura and migraine without aura could contribute the established variances in stroke risk between these migraine types. Therefore, we aimed to search if the frequency of hyperhomocysteinemia was different between these subtypes of migraine or not. Methods - We analyzed the findings of serum homocysteine levels in female migraineurs of 16-49 years old who admitted to our outpatient clinic. Results - Homocysteine level was elevated in 13.3% of study population. There were not any significant differences on median serum homocysteine levels between migraine with aura (8.0 mikromol/L) and without aura (8.5 mikromol/L). (p=0.426) The frequencies of hyperhomocysteinemia were also similar (9.1% versus 16.7%, respectively; p=0.373). Correlation analyses did not reveal any linear correlation between ages and homocysteine levels either in group of migraine with aura or in group of migraine without aura (p=0.417 and p=0.647, respectively). Similarly, any linear correlation between disease ages and homocysteine levels either in group of migraine with aura or in group of migraine without aura was not detected (p=0.359 and p=0.849, respectively). Conclusion - The median serum homocysteine levels and the frequencies of hyperhomocysteinemia are similar between migraine with aura and without aura in women of childbearing ages. Therefore, the variances on stroke risk ratios between these types of migraine are probably not originated from the differences of serum homocysteine status.

[Introduction - While examining patients with headache, abnormalities of unknown significance may quite frequently be encountered. In migraine small, subcortical, white matter abnormalities (WMAs) can be visualized by magnetic resonance images. The connection of these WMAs with the migraine is unclear, but some studies report the higher incidence of WMA in migraine. Patients and method - The authors reviewed the MR scans of their new migraine patients younger than 55 years treated in period of 15 months, and compared the data with a control group. Results - The prevalence of WMA was 10.3% among the migraineurs (78 patients without comorbidities such as hypertension, atherosclerotic heart disease, diabetes mellitus, autoimmun disorder or demyelinating disease) and it was 3.1% in the group of controls (32 persons younger then 55 years, and without migraine or other disease mentioned above). There were patients with WMA both below and above the age of 40; all of them were suffering from migraine without aura with 1 or more attack per month in variable times; none of them had smoked, the majority hadn't used oral contraceptive, and only a few of them used triptan or ergotamin. Conclusion - The data presented here shows that there is a relationship between migraine and WMA. The association of WMA and the risk of following stroke is not cleared. There are well known studies analysing the prevalence of silent infarction too, but we need a long prospective study to answer this question exactly.]

The effect of psychiatric comorbidities and stress-coping strategies on perceived quality of life in migraine


Purpose – Migraine is one of the most disabling primary headache conditions. We aimed to detect hidden symptoms of anxiety and depression and to survey stress-coping mechanisms and related quality of life in a large migraine population without any known psychiatric comorbidity. Method – 123 migraine patients (MG) and 66 healthy subjects (HC) completed the Beck Depression Inventory-II (BDI-II), the State and Trait Anxiety Inventory (S-STAI and T-STAI), the Stress and Coping Inventory (SCI) and the 36-Item Short Form Health Survey (SF-36). Results – MG patients reached significantly higher scores on the BDI-II and the T-STAI yielding previously undetected anxiety and depression symptoms. Significant differences were present on the SCI: higher stress scores and lower coping levels suggested impaired stress-coping strategies in migraine. MG patients achieved significantly lower scores on most of SF-36 subscales indicating lower perceived quality of life. Significant correlations were found between BDI-II, T-STAI, SCI scores and subscales of the SF-36. Conclusion – Unrecognized symptoms of anxiety and depression, as well as less effective stress-coping strategies might be related to the lower perceived quality of life in migraine. The screening of these symptoms might lead to more focused and efficient therapeutic strategies. Addressing stress management techniques could improve quality of life on the long-term.
