Publication Can ID MigraineTM be used as a screening test for adolescent migraine?(Blackwell Publishing, 2008-04-01) Zarifoğlu, Mehmet; Karlı, Necdet; Taşkapılıoğlu, Özlem; ZARİFOĞLU, MEHMET; KARLI, HAMDİ NECDET; Taşkapılıoğlu, Özlem; Tıp Fakültesi; Nöroloji Ana Bilim Dalı; 0000-0003-4436-3797; AAK-6623-2020; EHN-5825-2022; JDE-9380-2023Publication The expression and prognostic value of miR-146a and miR-155 in Turkish patients with multiple sclerosis(Taylor & Francis, 2022-03-04) Sarıdaş, Furkan; Ünlü, Havva Tezcan; Çeçener, Gülşah; Egeli, Ünal; Takanlou, Maryam Sabour; Takanlou, Leila Sabour; Tunca, Berrin; Zarifoğlu, Mehmet; Turan, Ömer Faruk; Taşkapılıoğlu, Özlem; SARIDAŞ, FURKAN; ÇEÇENER, GÜLŞAH; EGELİ, ÜNAL; TUNCA, BERRİN; ZARİFOĞLU, MEHMET; TURAN, ÖMER FARUK; Takanlou, Maryam Sabour; Takanlou, Leila Sabour; Taşkapılıoğlu, Özlem; 0000-0001-5945-2317; 0000-0002-0910-4258; 0000-0002-3820-424X; 0000-0001-7904-883X; 0000-0002-1590-4833; 0000-0002-6361-7150; 0000-0002-1619-6680; HSB-2700-2023; GYU-0252-2022; AAP-9988-2020; AAH-1420-2021; KGL-6846-2024; GRE-6268-2022; ABI-6078-2020; EHN-5825-2022; JDI-6091-2023; EBA-4926-2022Multiple sclerosis (MS) is an inflammatory, autoimmune demyelinating, and neurodegenerative disorder of the central nervous system. Interactions between environmental factors, predisposition genes, and determining genes appear to be involved in its etiology. Epigenetic mechanisms such as microRNA-mediated gene regulation can determine the susceptibility and severity of autoimmune diseases. Therefore, to determine the role of miR-146a and miR-155 in MS and its developmental stages, the expression levels in the serum of MS and clinically isolated syndrome (CIS) patients were compared with those of healthy controls. In the present study, the expression levels of miR-146a and miR-155 were assessed using quantitative Real-Time PCR in blood samples of 15 CIS patients and 61 relapsing-remitting multiple sclerosis (RRMS) patients alongside 32 healthy patients as controls. Furthermore, any associations with the clinicopathologic variables of the patients were also evaluated. Dysregulations were found only in the miR-146a and miR-155 expressions in the RRMS-Control group. When the RRMS patients were evaluated in terms of the characteristics of sex, annual attack rate, age of diagnosis, duration of follow-up, and immunomodulatory treatments used, no significant differences were observed. However, significant dysregulations were identified in miRNA expression in the vitamin D level, EDSS values, and the number of attacks. ROC curve analysis showed that miR-146a and miR-155 were significant in the RRMS-Control group for the area under the curve (AUC). It is possible that miR-146a may be associated with vitamin D deficiency and disease disability, while miR-155 may be associated with the number of attacks.Publication Our cases of secondary narcolepsy with three different etiology: Review of the literature(Galenos Yayınevi, 2015-09-01) Savrun, Yusuf; Demir, Aylin Bican; Sıvacı, Ali Özhan; Bora, İbrahim; Zarifoğlu, Mehmet; Savrun, Yusuf; BİCAN DEMİR, AYLİN; Sıvacı, Ali Özhan; ZARİFOĞLU, MEHMET; BORA, İBRAHİM HAKKI; Tıp Fakültesi; Nöroloji Ana Bilim Dalı; 0000-0001-6739-8605; 0000-0002-9697-9510; FUS-0738-2022; KHB-9765-2024; GCS-6691-2022; ENI-7759-2022; EHN-5825-2022Narcolepsy is neurological disorder classified among central hypersomnolences group and characterized by excessive daytime sleepiness, cataplexy, associated symptoms like hypnogogic/hypnopompic hallucinations and sleep paralysis. It is divided into two types on the basis of accompanying cataplexy. In the pathophysiology of this disorder, which is accused an autoimmune process, hypocretin deficiency in the hypothalamus was shown. Narcolepsy is often seen as a primary disease in young population but may also occur with other disorders like cerebrovascular diseases, intracranial tumors, encephalitis, sarcoidosis, multiple sclerosis or after head trauma, infections, and vaccines; in which the disease is accepted as secondary narcolepsy. In this case report, patients presenting with excessive daytime sleepiness and diagnosed as having secondary narcolepsy due to medical causes, and who have Parkinson's disease (PD), history of interferon use and hypothalamic involvement associated with Langerhans cell histiocytosis (LCH) were reported. Daytime sleepiness complaints should be well questioned in organic pathologies related with hypothalamus-pituitary system such as PD and similar diseases or in patients with history of drug use and secondary narcolepsy should be beared in mind.Publication The role of obstructive sleep apnea syndrome as a cause of stroke(Galenos Publ House, 2015-09-01) SARIDAŞ, FURKAN; BİCAN DEMİR, AYLİN; Demir, Aylin Bican; Zarifoğlu, Mehmet; ZARİFOĞLU, MEHMET; Bora, İbrahim; BORA, İBRAHİM HAKKI; 0000-0001-5945-2317; 0000-0001-6739-8605; JCE-6657-2023; HSB-2700-2023; V-7170-2017Obstructive sleep apnea syndrome (OSAS) is a highly prevalent sleep disorder. Stroke is the second leading cause of death and the third leading cause of disability in the world. OSAS and stroke has common risk factors, are associated with each other and are both reported to play an important role in the etiology of each other. OSAS and stroke association was identified in our two cases in whom sleep-related respiratory problems were encountered before stroke. We would like to draw attention to the importance of OSAS being among the risk factors in the etiopathogenesis of stroke.Publication Association of brain volume and cognition in the chronic and episodic migraine patients(Sage Publications, 2013-06-01) Zarifoğlu, Mehmet; Şener, D.

Understanding the characteristics of pain symptoms is crucial for a better clinical approach. Methods Patients who were diagnosed as having COVID-19 using reverse transcription-polymerase chain reaction were included in the study. Patients were asked to complete a 51-item questionnaire via a phone interview, which included questions on demographics, acute COVID-19 symptoms, the presence of pain symptoms, and their characteristics in the acute phase of COVID-19. Results A total of 222 out of 266 patients with COVID-19 participated in the study, yielding a response rate of 83.5%. A total of 159 patients reported at least one kind of pain syndrome with a prevalence of 71.6%. Myalgia was reported in 110 (49.6%) patients, headache in 109 (49.1%), neuropathic pain symptoms in 55 (24.8%), and polyarthralgia in 30 (13.5%) patients. A total of 66 patients reported only one type of pain, 46 reported two types, 42 reported three types, and five patients reported all four types of pain. Logistic regression analysis showed that there were significant associations between these pain syndromes and a strong association was found between neuropathic pain and headache. Conclusion Pain is a frequently observed symptom of mild-to-moderate COVID-19. There are significant relationships between pain syndromes in COVID-19, which may be due to a sequence of common etiologic factors. Significance This study described the main pain syndromes associated acute phase of mild-to-moderate COVID-19 and its associated features. Headaches and pain of neuropathic characteristics were prevalent in this sample.Publication Burden of headache(Sage Publications Ltd, 2008-04-01) Zarifoğlu, Mehmet; ZARİFOĞLU, MEHMET; Tıp Fakültesi; Noroloji Ana Bilim Dalı; EHN-5825-2022Publication Evaluation of the effects of botulinum toxin therapy on the clinical characteristics of pain and pain threshold value in patients with primary cervical dystonia(Journal Neurological Sciences, 2015-01-01) Özbek, Sevda Erer; Karlı Necdet; Yurtoğulları, Şükran; Zarifoğlu, Mehmet; Ocakoğlu, Gökhan; ERER ÖZBEK, ÇİĞDEM SEVDA; KARLI, HAMDİ NECDET; YURTOĞULLARI, ŞÜKRAN; ZARİFOĞLU, MEHMET; OCAKOĞLU, GÖKHANObjective: In 70% of patients with cervical dystonia (CD), the clinical presentation includes the symptom of pain. In this study, we aimed to define the types and clinical characteristics of the pain and to investigate whether this pain is a result of central sensitization by evaluating pre- and post-botulinum toxin (BoNT) treatment pain threshold values using electrical stimulation.Methods: The study enrolled a total of 35 patients with CD who received BoNT therapy. The patients were evaluated using the pain evaluation scale and Unified Dystonia Rating scale (UDRS) before and after BoNT therapy. The pain threshold values obtained from dystonic muscles, the contiguous or contralateral muscle without dystonic activity and a normal reference muscle with distant localization were recorded through electrical stimulation with EMG guidance, and all values obtained before and after BoNT therapy were compared.Results: No difference was found between the pain threshold values obtained from dystonic muscles before and after treatment. While no difference was observed across genders or VAS groups in terms of pain threshold values, the UDRS (duration and motor severity factor) scores showed significant decreases after treatment with BoNT in patients with painful dystonia and in patients with painless dystonia.Conclusions: The absence of a difference in pre- and post-BoNT treatment pain threshold values in dystonic muscles might be explained by the absence of central sensitization. Pain relief in dystonic patients might occur secondary to decreases in dystonic muscle contractions.Publication Migraine and E-TTH: Do they have similar clinical features and pathophysiologic mechanisms?(Blackwell Publishing Ltd, 2003-09-01) Karlı, Necdet; Zarifoğlu, Mehmet; Çalışkan, Nalan; KARLI, HAMDİ NECDET; ZARİFOĞLU, MEHMET; Çalışkan, Nalan; Tıp Fakültesi; Nöroloji Bölümü; JDE-9380-2023; EHN-5825-2022; EOX-5138-2022Publication The role of the dopamine β-hydroxylase functional polymorphism in patients with early-onset parkinson's disease in the Turkish population(Turkish Neurological Soc, 2021-03-01) Erer, Sevda; Eryılmaz, Işıl Ezgi; Çolak, Dilara Kamer; Egeli, Ünal; Çeçener, Gülşah; Tunca, Berrin; Karakuş, Ece; Çolakoğlu, Beril; Tokçaer, Ayşe Bora; Saka, Esen; Demirkıran, Meltem; Akbostancı, Cenk; Zarifoğlu, Mehmet; Doğu, Okan; Kaleagasi, Hakan; Kenangil, Gülay; Çakmur, Raif; Elibol, Bülent; ERER ÖZBEK, ÇİĞDEM SEVDA; ERYILMAZ, IŞIL EZGİ; Çolak, Dilara Kamer; EGELİ, ÜNAL; ÇEÇENER, GÜLŞAH; TUNCA, BERRİN; Karakuş, Ece; ZARİFOĞLU, MEHMET; Tıp Fakültesi; Nöroloji Ana Bilim Dalı; 0000-0001-7904-883X; 0000-0002-3316-316X; 0000-0002-2274-3230; 0000-0003-4968-2826; 0000-0002-3820-424X; 0000-0002-1619-6680; 0000-0003-2982-0961; GWV-3548-2022; AAH-1420-2021; DVY-9744-2022; JIP-4494-2023; AAP-9988-2020; ABI-6078-2020; FDA-2023-2022; EHN-5825-2022Objective: A functional single nucleotide polymorphism, rs1611115, in the dopamine beta-hydroxylase (DBH) gene, is reported to regulate plasma enzyme activity levels. Mere, we report the first evaluation of this association in patients with early-onset Parkinson's disease (EOPD) and healthy controls in the Turkish population.Materials and Methods: We evaluated the DBH rs1611115 polymorphism in 114 (64 male and 50 female) Turkish patients with EOPD and 58 sex- and age-matched healthy controls from the Turkish population. A total of 27.2% (n=31) of our patients who had any variation including pathogenic or non-pathogenic missense, non-sense and/or intronic variation with unknown significance in EOPD genes were grouped as "variation-positive EOPD". A total of 50.8% (n=58) of our patients were grouped as "variation and family history-negative EOPD" and the possible contribution of the DBH rs1611115 polymorphism to EOPD pathogenesis was evaluated in this group.Results: There was no significant difference in the genotypic and allelic frequencies of DBH rs1611115 between patients with EOPD and controls. To our knowledge, this is the first evaluation of the DBH rs1611115 polymorphism in patients with EOPD and ethnically matched controls in the Turkish population.Conclusion: Some previous studies have reported conflicting association results between DBH rs1611115 polymorphism and PD pathogenesis in different ethnic groups. Therefore, further studies are needed to evaluate dopamine metabolism-related generic variants and to determine their possible roles in EOPD susceptibility in the Turkish population.
