Background and Objectives: Migraine is the most common primary headache disorder worldwide, negatively affecting quality of life and limiting the functionality of individuals. Although its pathogenesis is not fully understood, it is known that activation of the trigeminovascular system, neurogenic inflammation, and oxidative stress are among the main components of migraine. In this context, we aimed to investigate the possible role of the nuclear factor erythroid 2-related factor 2 (Nrf2)/Kelch-like ECH-associated protein 1 (Keap1) signaling pathway, which plays a key role in the regulation of cellular oxidative stress, in the development of chronic diseases such as migraine. Materials and Methods: In this study, the oxidative stress parameters total oxidant level (TOS), total antioxidant level (TAS), and oxidative stress index (OSI) and changes in the Nrf2/Keap1 signaling pathway were analyzed in migraine patients. Results: The results showed that Keap1 levels were significantly higher in migraine patients compared with the control group, whereas the Nrf2 and TAS levels were low. In addition, increased levels of oxidized LDL (oxLDL) and glycogen synthase kinase-3 beta (GSK3B), which are oxidative stress markers, confirmed that the oxidative stress burden was high in migraine patients. The fact that OSI values were significantly higher in migraine patients clearly demonstrates that systemic oxidative stress was out of balance in these individuals. Conclusions: In conclusion, this study reveals that oxidative stress and the Nrf2/Keap1 signaling pathway play an important role in the pathogenesis of migraine. Decreased Nrf2 activity and increased Keap1 levels suggest that the antioxidant defense system is insufficient in migraine patients. These findings suggest that the Nrf2/Keap1 signaling pathway may be considered as a potential target for migraine treatment and that the development of new treatment strategies to reduce oxidative stress may be beneficial.

OBJECTIVES. We investigated whether there were atrophic changes in grey matter (pons, midbrain, and thalamus) in migraine patients. Vertebral artery diameters were also evaluated. MATERIAL AND METHODS. The cranial MRI images of 49 adult migraine-diagnosed patients and 49 adult subjects with normal cranial MRI results were included in the study. In both groups, pons, midbrain, and thalamus volumes, as well as vertebral artery diameters were measured. RESULTS. There were no significant differences between pons, midbrain, bilateral thalamus volumes and vertebral artery diameters of the migraine and control groups (p>0.05). In the right-sided migraine group, the right thalamus volume was significantly lower than the contralateral side (p0.05). In the right-sided and left-sided migraine groups, left vertebral artery diameters were significantly higher than those on the right side (p<0.05). In older migraine patients, pons and midbrain volumes decreased (p<0.05). In longer migraine duration, pons volume decreased (p<0.05). In aura-present migraine patients, right vertebral artery diameters decreased (p<0.05). CONCLUSION. We concluded that migraine is related to grey matter atrophy in terms of thalamus atrophy on the migraine side. Pons atrophy in longer migraine, and pons and midbrain atrophy in older migraine patients were also detected. Therefore, during the follow-up of the migraine patients, grey matter atrophy should be examined by MRI, and treatment to prevent migraine attacks should be planned.

All serotypes block the release of the essential neurotransmitter acetylcholine at the neuromuscular junction, causing muscle paralysis. Cosmetological applications include a range of treatments, from correcting lines, wrinkles, and creases on the face, chin, neck, and chest area to dermatological applications such as hyperhidrosis. Botulinum toxin injections are generally well-tolerated and have few side effects. We present a case of botulism that was affected by Botox treatment of the forehead and axillae in an external clinic. Ten days later, Botox was administered to the soles of the feet for sweating. The patient, whose complaints had increased over the past 2 days, contacted our emergency department with these complaints. The patient, who was admitted to the neurology clinic with the preliminary diagnosis of iatrogenic botulism and whose vitals were stable the patients reported in the recent studies developed a syndrome similar to botulism after intramuscular injections of therapeutic doses of onabotulinum toxin derived from two different batches of the drug. In the first patient, these symptoms occurred after only one dose, while in the second patient, they occurred after five years of regular treatment with the toxin. Clinically detectable weakness was present in the extraocular, bulbar, trunk, and limb muscles, and EMG changes were recorded in all muscles tested. The muscle weakness and EMG changes resolved a few weeks later.

Objective: We investigated the volumetric changes of the brain structures and trigeminal nerve diameters in cluster headache (CH) by cranial MRI. Methods: The cranial MRI images of 30 adult patients with CH and 30 adult subjects with normal cranial MRI results were included. In both groups, pons, midbrain, thalamus, and hippocampus volumes; and trigeminal nerve diameters were measured. Results: There were no significant differences between pons (p=0.849), midbrain (p=0.855), bithalamic (p=0.553Right, p=0.523Left), and hippocampus volumes (p=0.930Right, p=0.698Left). In CH group, trigeminal nerve diameter (2.38±0.47 mm) was non-significantly higher than the control group (2.29±0.44 mm) (p=0.131). In the CH group, left thalamus and right hippocampus volumes were significantly higher than the contralateral side (p<0.05). In CH group, there were positive correlations between the pons and thalamus (p=0.037Right and p=0.037Left) and hippocampus volumes (p=0.002Right, p=0.005Left); midbrain and bithalamic volumes (p=0.001Right, p=0.001Left); and right trigeminal nerve diameter (p=0.029); thalamus and pons(p=0.037Right, p=0.037Left); and midbrain volumes (p=0.001Right, p=0.001Left); right and left hippocampus volumes (p=0.000); right and left trigeminal nerve diameters (p=0.000). In females, right hippocampus volumes were smaller than those in males (r= ˗0.374, p=0.042). Conclusion: In CH patients, left thalamus volume was higher; and left hippocampus volume was lower. In CH patients, the limbic system and especially left hippocampus may be affected and get lower in volumetric analysis. Additionally, the right thalamus is affected showing lower volume in CH patients.

Amaç: Bu çalışmada tıp fakültesi son sınıf öğrencilerinin, disleksi konusunda bilgi düzeyinin belirlenmesi amaçlandı. Yöntem: Bu çalışma 15-20 Eylül 2021 tarihleri arasında Gaziantep Üniversitesi Tıp Fakültesinde eğitim gören 252 son sınıf öğrencisi ile gerçekleştirildi. Öğrencilere sosyodemografik ve eğitim özelliklerini, disleksi konusunda bilgilerini sorgulayan anket uygulandı. Katılımcıların bilgi düzeyi sorulan 20 soru için, 20 puan üzerinden değerlendirildi. Bulgular: Çalışmamızda yer alan öğrencilerin 144’u (%57,1) erkek, 108’si (%42,9) kadın, yaş ortalaması ise 24.65±1.78 (min=21, max=39) olarak tespit edildi. ‘Disleksi terimini daha önce duydunuz mu?’ sorusuna katılımcıların 235’si (%93,3) evet, 17’si (%6,7) hayır yanıtını verdi. Öğrencilerin 68’si (%27,0) disleksi konusunda özel bir eğitim aldığını, 184’ü (%73,0) ise almadığını belirtti. Katılımcıların disleksi konusunda bilgi puanı ortalaması 9,45± 2,46 (min=0, max=17) olarak saptandı. ‘Disleksi bir özel öğrenme bozukluğudur’ doğru önermesine öğrencilerin 235’i (%93,3) katıldığını belirtti. Çalışmamızda en az bilinen önermeler ‘Dislekside renkli obje kullanımı ve renkli kaplamaların kullanılması yardımcı olur’ yanlış ifadesine katılımcıların 163’ünün (%64,7) katıldığı, 85’inin (%33,7) ise bu konuda fikri olmadığı belirlendi. ‘Disleksi kaynaklı zorlukların iyileştirilmesinde göz takip egzersizlerinin yapılması etkilidir’ yanlış önermesine öğrencilerin 159’u (%63,1) katılıyorum, 87’si (%34,5) ise fikrim yok şeklinde yanıt verdi. Sonuç: Çalışmamızda tıp fakültesi son sınıf öğrencilerinin disleksi konusunda ciddi bilgi yanlışlıkları ve eksiklikleri olduğu belirlendi. Bu duruma öğrencilerin disleksiye yönelik eğitimi az bir kısmının almış olması sebep olmuş olabilir. Disleksi ile mücadelede Üniversiteler, Milli Eğitim ve Sağlık Bakanlığının ortak projeler gerçekleştirmesi ve etkin bir yöntem olarak basın yayın organlarını kullanması önem taşımaktadır.
