    Alpha-synuclein levels in multiple sclerosis patients with restless leg syndrome
    (Cukurova Univ, Fac Medicine, 2020) Cakina, Suat; Yucel, Selma; Polat, Cemre Cagan; Ozturk, Samil
    Purpose: The restless legs syndrome is more frequent and critical in Multiple Sclerosis patients, and it harms their general well-being and life quality. Alpha-synuclein is a synuclein protein that can have an impact on the pathway of signaling, affecting the Dopamin 2 receptor and its receptor trafficking. Studies have shown that the decrease in dopamine 2 receptor and Restless Legs Syndrome disease are correlated. This study is aimed to ascertain the alpha-synuclein level in multiple sclerosis patients with restless legs syndrome. Materials and Methods: We took blood samples from 40 multiple sclerosis patients and 20 healthy individuals. Half of the patient group had Multiple Sclerosis with restless leg syndrome. In the study groups, the alpha-synuclein level was determined by quantitative real-time polymerase chain reaction (qRT-PCR) and enzyme-dependent immunosorbent assay (ELISA). Results: Alpha-synuclein gene expression level was found or be significantly lower in restless leg syndrome patients with multiple sclerosis than the Alpha-synuclein gene expression level in the control group. Conclusion: Alpha-synuclein may have an impact on the pathogenesis of the restless leg syndrome of multiple sclerosis disease. Further investigations are required to determine the impact of alpha-synuclein in the pathogenesis of restless leg syndrome in multiple sclerosis disease.

    Cognitive functions, fatigue, depression, anxiety, and sleep disturbances: assessment of nonmotor features in young patients with essential tremor
    (Springer Heidelberg, 2015) Sengul, Yildizhan; Sengul, Hakan S.; Yucekaya, Sevda K.; Yucel, Selma; Bakim, Bahadir; Pazarci, Nevin K.; Ozdemir, Gokhan
    There is a growing amount of evidence to suggest that besides motor features, patients with essential tremor (ET) may exhibit significant nonmotor features, such as mild cognitive deficits, fatigue, neuropsychiatric symptoms, and sleep disturbances. The goal of this study was to examine nonmotor features in young patients with ET and their impact on quality of life. 45 patients (24.55 +/- 7.16 years old) with ET and 35 controls were evaluated using the Pittsburgh Sleep Quality Index, Epworth Sleepiness Scale, Beck Depression Inventory, Beck Anxiety Scale, Fatigue Severity Scale, and Short Form-36. Cognitive functions were evaluated using the Turkish version of the Montreal Cognitive Assessment Battery (MoCA). We ruled out other possible causes of the tremor. The tremor rate was evaluated using the Fahn-Tolosa-Marin Tremor Rating Scale. Poor sleep quality, fatigue, anxiety, and depressive symptoms were more common, and MoCA total scores were lower in the patient group. Fatigue, depressive symptoms, and higher anxiety levels were seen to have a negative effect on physical and mental health. Excessive daytime sleepiness had a negative effect on physical health. There is an emerging interest in nonmotor features of ET. This study showed that even young patients have nonmotor features that decrease their quality of life. This might tell us that nonmotor symptoms could be a part of the disease in the early stages.

    Epilepsy After Bee Sting: Case Report
    (Kare Publ, 2018) Polat, Cemre Cagan; Yucel, Selma; Tan, Tulay; Ozisin Karaman, Handan Isin
    Bee envenomations are one of the most common in all insect venomations. The usual clinical manifestation is local inflamation findings with a sudden burning pain. Rarely anaphylaxis, anxiety disorders, headache, chest pain, myocardial infarction, organ dysfunction and neurological disorders are reported. Bee venom has many components and these components have different effect on nervous system.

    Relationship between genetic polymorphisms MTHFR (C677T, A1298C), MTR (A2756G) and MTRR (A66G) genes and multiple sclerosis: a case-control study
    (Termedia Publishing House Ltd, 2019) Cakina, Suat; Ocak, Ozgul; Ozkan, Adile; Yucel, Selma; Karaman, Handan Isin Ozisik
    Recent studies have reported elevated plasma homocysteine and reduced folate and vitamin B levels in patients with multiple sclerosis (MS). In this study, we aimed to investigate the association between MS and the following four DNA polymorphisms: MTR A[2756]G, MTHFR C[677]T, MTHFR A[1298]C and MTRR A[66]G. The DNA polymorphisms were genotyped in 80 patients with confirmed MS and 80 healthy control age- and gender-matched subjects using PCR-RFLP approach. Our results show that the frequency of the T/T genotype homozygotes for the MTHFR C[677]T polymorphism was significantly higher in patients than in controls (p = 0.04, OR: 3.16, 95% CI: 1.23-8.17). In turn, the A/A genotype of the MTHFR A[1298]C polymorphism was more frequent in controls than in patients (41.3% vs. 32.5%, p = 0.04). There were no differences in distribution of genotypes for the MTR A[66]G and MTR A[2756]C polymorphisms between patients with MS and controls (p > 0.05). Our findings suggested that the MTHFR C[677]T and MTHFR A[1298] C gene polymorphisms might be associated with MS as genetic factors influencing the risk of the disease.

    Review of Seizures That Triggered by Energy Drinks With Two Cases
    (Kare Publ, 2020) Polat, Cemre Cagan; Yucel, Selma; Ozisik Karaman, Handan Isin
    Epilepsy is a disease that occur with abnormal discharge of brain neurons.Energy drinks use ise common in young people nowadays and that can trigger epileptic seizure.Taurine and caffeine as intense ingredients are being hold responsible of abnormal discharge.In this case we review relationship between seizures and energy drink with two cases.

    Sleep disturbances and excessive daytime sleepiness in migraine: A comparison between comorbidities and disability
    (Springer London Ltd, 2015) Sengul, Yildizhan; Sengul, Hakan S.; Bakim, Bahadir; Yucekaya, Sevda K.; Yucel, Selma; Akgun, Mucella
    Many studies have investigated the association between headache and sleep disorders, but few have focused on migraine. The goal of this study was to evaluate sleep disturbance and excessive daytime sleepiness (EDS) in relation to migraine disability. 120 migraine patients who were diagnosed according to The International Classification of Headache Disorders-II and 45 healthy controls were recruited for the study. All participants completed the Pittsburg Sleep Quality Index (PSQI), the Epworth Sleepiness Scale, Beck Depression Inventory and Beck Anxiety Scale. Migraineurs completed Migraine Disability Assessment Scale (MIDAS) and Visual Analog Scale. The prevalence of poor sleep was 83.3% in the patients and 22.2% in the controls. All PSQI subgroup scores were higher for the patients than the controls except Hours asleep. EDS was more prominent in the patient group (19.2% vs 2.2%). In conclusion, sleep disturbance, EDS, anxiety, and depressive symptoms were detected more commonly in migraine patients and were correlated with the migraine-related disability. The results of multivariate regression analysis indicated that EDS and sleep disturbance were the most effective factors on disability.

    Vitamin D receptor gene polymorphisms in multiple sclerosis disease: A case-control study
    (Univ Press, 2018) Cakina, Suat; Ocak, Ozgul; Ozkan, Adile; Yucel, Selma; Karaman, Handan Isin Ozisik
    Multiple sclerosis (MS) is a common neurologic disorder that is a chronic inflammatory, demyelinating, and neurodegenerative disease of the central nervous system (CNS). Its etiology remains unknown. Several recent studies have found that decreased susceptibility to vitamin D deficiency is also associated with a decreased risk of MS. The role of vitamin D receptor (VDR) gene and its polymorphisms are highlighted as susceptible components. In this study, we aimed to identify the relationship between Apal (rs7975232), BsmI (rs 1544410), and TaqI (rs731236) gene polymorphisms with MS. Apal, Bsml, and TaqI genotypes were determined in 70 patients with MS and in 70 control subjects. DNA was isolated from blood samples, and then Apal, BsmI and TaqI gene polymorphisms were identified using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) assay. The distribution of BsmI and TaqI polymorphisms did not show any significant differences in MS patients and controls; however, increased A allele of Apal polymorphism was found in MS patients. Our findings suggest that the Apal gene polymorphism might be associated with MS. Investigation of a larger population and functional work on these gene structures and function in MS patients are recommended.
