- Abstract
BACKGROUND: Bipolar disorder is associated with circadian disruption and a high risk of suicidal behavior. In a previous exploratory study of patients with bipolar I disorder, we found that a history of suicide attempts was associated with differences between winter and summer levels of solar insolation. The purpose of this study was to confirm this finding using international data from 42% more collection sites and 25% more countries. METHODS: Data analyzed were from 71 prior and new collection sites in 40 countries at a wide range of latitudes. The analysis included 4876 patients with bipolar I disorder, 45% more data than previously analyzed. Of the patients, 1496 (30.7%) had a history of suicide attempt. Solar insolation data, the amount of the sun's electromagnetic energy striking the surface of the earth, was obtained for each onset location (479 locations in 64 countries). RESULTS: This analysis confirmed the results of the exploratory study with the same best model and slightly better statistical significance. There was a significant inverse association between a history of suicide attempts and the ratio of mean winter insolation to mean summer insolation (mean winter insolation/mean summer insolation). This ratio is largest near the equator which has little change in solar insolation over the year, and smallest near the poles where the winter insolation is very small compared to the summer insolation. Other variables in the model associated with an increased risk of suicide attempts were a history of alcohol or substance abuse, female gender, and younger birth cohort. The winter/summer insolation ratio was also replaced with the ratio of minimum mean monthly insolation to the maximum mean monthly insolation to accommodate insolation patterns in the tropics, and nearly identical results were found. All estimated coefficients were significant at p < 0.01. CONCLUSION: A large change in solar insolation, both between winter and summer and between the minimum an

- Abstract
Objective: To confirm prior findings that the larger the maximum monthly increase in solar insolation in springtime, the younger the age of onset of bipolar disorder. Method: Data were collected from 5536 patients at 50 sites in 32 countries on six continents. Onset occurred at 456 locations in 57 countries. Variables included solar insolation, birth-cohort, family history, polarity of first episode and country physician density. Results: There was a significant, inverse association between the maximum monthly increase in solar insolation at the onset location, and the age of onset. This effect was reduced in those without a family history of mood disorders and with a first episode of mania rather than depression. The maximum monthly increase occurred in springtime. The youngest birth-cohort had the youngest age of onset. All prior relationships were confirmed using both the entire sample, and only the youngest birth-cohort (all estimated coefficients P < 0.001). Conclusion: A large increase in springtime solar insolation may impact the onset of bipolar disorder, especially with a family history of mood disorders. Recent societal changes that affect light exposure (LED lighting, mobile devices backlit with LEDs) may influence adaptability to a springtime circadian challenge.

Aim: Realizing migraine comorbidities is particularly important for physiopathology, treatment, and progress of the disease. In the present study, we aimed to assess the comorbid conditions in patients with migraine. Method: This retrospective study was conducted by the Turkish Headache Database Study Group, at 23 headache centers. Diagnosis of migraine was established by a physician based on the International Classification of Headache Disorders-II criteria. Comorbidities of migraine were determined based on the patients' self reports. Results: A total of 3478 cases, which have been diagnosed with migraine were evaluated. (mean age 43.5±11.2, 81.8% female). Comorbidity was detected in 55.7% (n:1937) of overall cases. Psychiatric diseases have been reported to be the most prevalent comorbidity in these patients (31.5%, p?0.0001). Cardiovascular diseases (16.5%), and hypertension (16.3%) have been found to be more prevalent in migraine with aura. Prevalence of neurological comorbidity, also, was higher in migraine with aura. Epilepsy (1.5%) and vertigo (4.6%) were detected in migraine with aura cases. Difficulty in falling asleep was found in 35.4% of the cases (p?0.0001). Prevalence of non-headache pain was found to be 2.9% (p>0.0001).?0.0001). Patients with comorbidities were more sensitive to migraine triggers and accompanied symptoms were more severe (p?0.0001). Conclusion: Comorbidity of migraine is the important component of complex nature of the disease. The present study is important in terms of being the first multicenter study exposing migraine comorbidities and their reflections in clinical practice.

Treatment ,Cluster headache ,Methylprednisolone - Abstract
Cluster headache is characterized by unilateral severe periorbital hemicranial pain. It is the most frequent form of trigemino-autonomic headaches. Diagnosis is straightforward after a thorough history taking and neurologic examination. Attack treatment and prophylactic therapy should be considered in all cases. Treatment might be challenging particularly in cluster headaches. In this study, treatment period and its results are presented in four cluster headache cases (52, 71, 48 and 28 years old) with drug resistant attacks. One gr of methylprednisolone was administered to all four cases for 3 days accompanied by prophylactic treatment. Attack severity and frequency subsided gradually after the treatment followed by a complete recovery. Remission periods were prolonged. Regarding these cases, we concluded that high dose steroid therapy might be efficient in chronic cluster headaches.

Informant questionnaire on cognitive decline in elderly (IQCODE) scoring ,Delirium rating scale ,Cholinergic hyperintensities pathway scale (CHIPS) ,Acute confusional state (ACS) ,National institute of health stroke scale (NIHSS) - Abstract
Acute confusional state is a change of mental status with sudden onset and fluctuating course. This study was aimed at determining the frequency of ACS that appears at early (acute) stage of stroke, its predisposing factors, and its impact on prognosis. Material and Method: 150 cases were included in this study which was performed prospectively. ACS was diagnosed on the basis of DSM-IV criteria and of Delirium Rating Scale. Pre-stroke cognitive functions were evaluated according to Informant Questionnaire on Cognitive Decline in Elderly scoring. White matter hyperintensities detected on cerebral magnetic resonance imaging were classified according to Cholinergic Hyperintensities Pathway Scale scoring. Results: The rate of ACS was determined as 28% in cases who experienced stroke. Advanced age, presence of cognitive decline, use of anticholinergic drugs during pre-stroke period and in acute stage, ischemic heart disease, hemorrhagic stroke, concomitant, infectious and metabolic problems, concurrent neglect and/or anosognosia phenomenon, advanced stage leukoaraiosis, high National Institute of Health Stroke Scale, Colinergic Hyperintensities Pathway Scale and Informant Questionnaire on Cognitive Decline in Elderly scores increase the possibility of entering acute confusional state. Functional and vital prognoses follow a poorer course in those who enter ACS than in those who do not. Conclusion: Cases who experienced stroke should be monitored closely, particularly in acute stage, with respect to cognitive changes. In the acute stage of stroke, diagnosing and treating metabolic and infectious problems that may cause ACS, and avoiding as much as possible anticholinergic medications is (are) important in terms of preventing the manifestation.

- Abstract
Objectives: To evaluate the effects of corrected QT dispersion (QTcd) on patients' prognosis with early stage non-lacunar ischemic stroke, regardless of location of the lesion. Methods: In this non-randomized prospective study, stroke patients were evaluated in the intensive care unit of Cukurova University Hospital, School of Medicine, Adana, Turkey, from 2002-2003. Neurologic symptoms of all subjects were recorded according to Glasgow Coma Scale (GCS) and Canadian Neurological Scale. Subtypes of stroke were defined according to the Oxfordshire Community Stroke Project classification. Patients with GCS between 7 and 11 were included in the study. Electrocardiograms of the patients were collected in the first 6 hours. Corrected QT (QTc) were calculated by the Bazzett formula. Corrected QT dispersion was defined as maximum minus minimum QT interval. Results: A total of 148 (74 male) consecutive acute stroke patients, aged between 36-90 years (mean 63.07 ± 12.55), were divided into 2 groups. Group I consisted of surviving patients (n=109) and Group II consisted of expired patients (n=39). There were no statistically significant differences in the mean age, gender distribution, frequency of hypertension, diabetes mellitus, and coronary artery disease between the groups. Group II (7.4 ± 3.7) had significantly higher QTcd (7.4 ± 3.7) compared to Group I (p=0.002). Conclusion: This study shows the value of QTcd in predicting patients' prognoses with early stage non-lacunar ischemic stroke, regardless of location of the lesion.

PubMedID: 18390026 Background: Headache in patients with systemic lupus eryhtematosus (SLE) is considered a common neurological finding, although the relationship is unclear. Another obscure point is the relationship between headache and neuroradiologic findings in these patients. Aim: In this study, we aimed to evaluate the correlation between headache characteristics and intracranial lesions in SLE patients. Methods and Results: Forty-eight SLE patients were chosen from those referred to our clinic depending on the American Collage of Rheumatology (ACR) criteria at the same time or after the diagnosis of SLE. Headache classification was done regarding the ICD-II criteria in the patients. Headache severity was assessed by visual analog scale (VAS), and subjects with VAS ?4 were included in the study. Patients were divided into two groups according to magnetic resonance imaging (MRI) findings: abnormal MRI (lesion positive) and normal MRI (lesion negative). On MRI, intracranial lesions were detected in 37.5 % (n=18) of the patients, and no lesion was found in 62.5% (n=30). Headache characteristics were as tension type in 54.1% (n=26) and migraine like in 39.6% (n=19) of all patients. Imaging findings were mostly as periventricular and subcortical focal lesions, ranging from 3-22 mm in diameter. A significant correlation was found between abnormal MRI findings with advanced age and prolonged disease duration (p=0.018, p=0.016). Conclusions: As a conclusion, a detailed neurologic evaluation and radiologic investigation, if necessary, should be performed in SLE patients with prolonged disease and advanced age, regardless of headache characteristics.

PubMedID: 15389979 We report on the development of transient parkinsonism after progesterone injection in a pregnant patient with a risk of abortion. Etiological possibilities are discussed, including pregnancy itself, possible toxic effects of the dead fetus, and progesterone injection. Progesterone-induced parkinsonism seems the most likely diagnosis in this case. © 2004 Movement Disorder Society.

Background Bipolar disorder is associated with circadian disruption and a high risk of suicidal behavior. In a previous exploratory study of patients with bipolar I disorder, we found that a history of suicide attempts was associated with differences between winter and summer levels of solar insolation. The purpose of this study was to confirm this finding using international data from 42% more collection sites and 25% more countries. Methods Data analyzed were from 71 prior and new collection sites in 40 countries at a wide range of latitudes. The analysis included 4876 patients with bipolar I disorder, 45% more data than previously analyzed. Of the patients, 1496 (30.7%) had a history of suicide attempt. Solar insolation data, the amount of the sun’s electromagnetic energy striking the surface of the earth, was obtained for each onset location (479 locations in 64 countries). Results This analysis confirmed the results of the exploratory study with the same best model and slightly better statistical significance. There was a significant inverse association between a history of suicide attempts and the ratio of mean winter insolation to mean summer insolation (mean winter insolation/mean summer insolation). This ratio is largest near the equator which has little change in solar insolation over the year, and smallest near the poles where the winter insolation is very small compared to the summer insolation. Other variables in the model associated with an increased risk of suicide attempts were a history of alcohol or substance abuse, female gender, and younger birth cohort. The winter/summer insolation ratio was also replaced with the ratio of minimum mean monthly insolation to the maximum mean monthly insolation to accommodate insolation patterns in the tropics, and nearly identical results were found. All estimated coefficients were significant at p

- Abstract
Background: Migraine is a disease characterized by headache attacks. The disease is multifactorial in etiology and genetic and environmental factors play role in pathogenesis. Migraine can also be accompanied by psychiatric disorders like neurotism and obsessive compulsive disorder. Stress, hormonal changes and certain food intake can trigger attacks in migraine. Previous studies showed that eating attitudes and disorders are prevalant in patients with migraine. Eating disorders are psychiatric disorders related to abnormal eating habits. Both migraine and eating disorders are common in young women and personality profiles of these patient groups are also similar. A possible relationship which shows that migraine and eating habits are related can lead to a better understanding of disease pathogenesis and subsequently new therapeutic options on both entities. Association of migraine in relation to severity, depression and anxiety and eating habits and disorders were aimed to be investigated in this study., Methods: The study was designed as a prospective, multi-center, case control study. Twenty-one centers from Turkey was involved in the study. The gathered data was collected and evaluated at a single designated center. From a pool of 1200 migraine patients and 958 healthy control group, two groups as patient group and study group was created with PS matching method in relation to age, body-mass index, marital status and employment status. Eating Attitudes Test-26 (EAT-26), Beck's Depression Inventory (BDI) and Beck's Anxiety Inventory (BAI) were applied to both study groups. The data gathered was compared between two groups., Results: EAT-26 scores and the requirement for referral to a psychiatrist due to symptoms related to eating disorder were both statistically significantly higher in patient group compared to control group (p = 0.034 and p = 0.0001 respectively). Patients with migraine had higher scores in both BDI and BAI compared to control group (p = 0.0001 and p = 0.0001 respectively). Severity of pain or frequency of attacks were not found to be related to eating attitudes (r:0.09, p = 0.055)., Conclusions: Migraine patients were found to have higher EAT-26, BDI and BAI scores along with a higher rate of referral to a psychiatrist due to symptoms. Results of the study showed that eating habits are altered in migraine patients with higher risk of eating disorders. Depression and anxiety are also found to be common amongst migraine patients., (© 2024. The Author(s).)

- Abstract
Introduction: Capecitabine is a pre-metabolite of 5-fluorouracil and is used as a chemotherapeutic agent. Among the common side effects of capecitabine, there are gastrointestinal side effects including nausea, vomiting, and diarrhea, and dermatological side effects including hand-foot syndrome and skin pigmentation change. However, neurological side effects of capecitabine are very rare. We describe herein a patient who developed neurological side effects in the form of agraphia and dysarthria on the 7th day of capecitabine treatment., Case Report: A 34-year-old male patient, who was being followed up with the diagnosis of colon cancer, presented with speech and writing disorder that developed while under capecitabine treatment. Dysarthria and agraphia were detected in his neurological examination. Diffusion-weighted magnetic resonance imaging (MRI) revealed acute diffusion restriction in the splenium of the corpus callosum and at the level of the bilateral centrum semiovale. Brain MRI revealed symmetrical T2-weighted fluid-attenuated inversion recovery (T2-FLAIR) signal increases at the right temporoparietal medial, corpus callosum level, and bilateral white matter level., Management & Outcome: The capecitabine treatment was terminated, and methylprednisolone treatment was administered and plasmapheresis procedure was carried out. Subsequently, significant improvement was observed in the clinical findings and neuroimaging., Discussion: Capecitabine is used as an oral agent; thus, it provides ease of use. Neurological side effects associated with the use of capecitabine reportedly occur very rarely. The findings of this case demonstrated that leukoencephalopathy can be seen during the use of capecitabine, imaging results are very important in the diagnosis of leukoencephalopathy, and improvement can be achieved with the termination of the capecitabine treatment.

- Abstract
Background and Aim: The nonsatisfaction among emergency medicine specialty trainees is an underrated issue in Turkey. Several previous studies have evaluated the burn-out and its consequences among physicians, but there is no study conducted with specialty trainees. The aim of this study is to evaluate the reasons for resignation among emergency medicine specialty residents in Turkey., Method: A total of 41 participants, who resigned from emergency medicine residency, were contacted by phone and invited to complete an online survey that included 25 questions about personal characteristics and departmental information., Results: Most frequent reasons of resignation were violence/security concerns (63.4%), busy work environment (53.7%), and mobbing (26.8%). Participants who reported that they have resigned due to inadequate training were mostly over 30 years old (p=0.02), continued more than 6 months to EMST (p<0.001), reported that there was no regular rotation program (p=0.003) or access to full-text scientific journals (p=0.045) in their department. All participants thought that there were deficits in the training programs, and none of them declared regret for resigning. Twenty-eight participants (68.2%) continued their specialty training at a different discipline after resignation., Conclusion: Major barriers against a high-quality and sustainable emergency medicine residency are violence in emergency services, mobbing in academic or administrative bodies, and inaccessibility to scientific resources. These obstacles can only be removed by cooperation of multiple institutions in Turkey.

- Abstract
Introduction: Angiography headache is defined as a new headache caused directly by cerebral angiography. We aimed to investigate the prevalence and clinical characteristics of angiography headache, and its relationship with primary headaches., Material and Methods: This single-centre prospective cohort study was carried out in our tertiary healthcare centre. Patients who had undergone a diagnostic cerebral angiography procedure between March 2016 and June 2017 were included in the study. During and after the procedure, we evaluated the patients in terms of occurrence of headache, and, if present, details about time to onset of headache after cerebral angiography, duration of headache, accompanying symptoms (nausea, vomiting, photophobia and phonophobia), and degree and severity of pain., Results: A total of 226 patients were included in the study. The prevalence of angiography headache was found to be 22.1% (n = 50). While angiography headache started in the first six hours in 92% (n = 46) of the patients, it started after 24 hours of the angiography procedure in only 4% (n = 2). Compressive headache was the most common type, described by 64% of the patients, whereas 4% of the patients described pricking or stabbing sensations. Angiography headache was associated with female gender, higher educational level, and a history of primary headache., Conclusion: Angiography headache is an important clinical entity that must be considered during and after angiography. Experiencing angiography headache is more common among patients with a history of primary headache.

- Abstract
Silent embolic cerebral infarction (SECI) is a major complication of coronary angiography (CAG) and percutaneous coronary intervention (PCI). Patients with stable coronary artery disease (CAD) who underwent CAG with or without PCI were recruited. Cerebral diffusion-weighted magnetic resonance imaging was performed for SECI within 24 hours. Clinical and angiographic characteristics were compared between patients with and without SECI. Silent embolic cerebral infarction occurred in 12 (12%) of the 101 patients. Age, total cholesterol, SYNTAX score (SS), and coronary artery bypass history were greater in the SECI(+) group (65 ± 10 vs 58 ± 11 years,P= .037; 223 ± 85 vs 173 ± 80 mg/dL,P= .048; 30.1 ± 2 vs 15 ± 3,P< .001; 4 [33.3%] vs 3 [3.3%],P= .005). The SECI was more common in the PCI group (8/24 vs 4/77,P= .01). On subanalysis, the SS was significantly higher in the SECI(+) patients in both the CAG and the PCI groups (29.3 ± 1.9 vs 15 ± 3,P< .01; 30.5 ± 1.9 vs 15.1 ± 3.2,P< .001, respectively). The risk of SECI after CAG and PCI increases with the complexity of CAD (represented by the SS). The SS is a predictor of the risk of SECI, a complication that should be considered more often after CAG., (© The Author(s) 2015.)

- Abstract
Objective: To evaluate the effects of corrected QT dispersion (QTcd) on patients` prognosis with early stage non-lacunar ischemic stroke, regardless of location of the lesion., Methods: In this non-randomized prospective study, stroke patients were evaluated in the intensive care unit of Cukurova University Hospital, School of Medicine, Adana, Turkey, from 2002-2003. Neurologic symptoms of all subjects were recorded according to Glasgow Coma Scale (GCS) and Canadian Neurological Scale. Subtypes of stroke were defined according to the Oxfordshire Community Stroke Project classification. Patients with GCS between 7 and 11 were included in the study. Electrocardiograms of the patients were collected in the first 6 hours. Corrected QT (QTc) were calculated by the Bazzett formula. Corrected QT dispersion was defined as maximum minus minimum QT interval., Results: A total of 148 (74 male) consecutive acute stroke patients, aged between 36-90 years (mean 63.07 +/- 12.55), were divided into 2 groups. Group I consisted of surviving patients (n=109) and Group II consisted of expired patients (n=39). There were no statistically significant differences in the mean age, gender distribution, frequency of hypertension, diabetes mellitus, and coronary artery disease between the groups. Group II (7.4 +/- 3.7) had significantly higher QTcd (7.4 +/- 3.7) compared to Group I (p=0.002)., Conclusion: This study shows the value of QTcd in predicting patients` prognoses with early stage non-lacunar ischemic stroke, regardless of location of the lesion.

- Abstract
In this prospective study, we aimed to determine the prevalence of migraine and non-migraine headaches using a questionnaire, including ID Migraine, for university students. The study was designed cross-sectionally and a questionnaire consisting of 43 questions was applied to 1,256 students. The questionnaire consisted of questions related to demographic, social, curriculum, housing and headache characteristics of the subjects. Three-item screening questions of the ID Migraine test were included at the end of the questionnaire aimed at migraine diagnosis. The mean age of 1,256 students (529 females and 727 males) enrolled in this study was 21.9 +/- 2.1 years (17-31 years). Migraine-type headache was detected in 265 subjects (21.9%) based on the ID Migraine evaluation. Of these, 145 (54.7%) were female and 120 (45.3%) were male (female/male ratio: 1.2/1). Non-migraine-type headache was identified in 864 subjects, with 357 females and 507 males. As a conclusion, ID Migraine screening test might be practical and beneficial when a face-to-face interview is not possible or to pre-determine the subjects for a face-to-face interview for migraine diagnosis in larger populations.

Background: Headache in patients with systemic lupus eryhtematosus (SLE) is considered a common neurological finding, although the relationship is unclear. Another obscure point is the relationship between headache and neuroradiologic findings in these patients., Aim: In this study, we aimed to evaluate the correlation between headache characteristics and intracranial lesions in SLE patients., Methods and Results: Forty-eight SLE patients were chosen from those referred to our clinic depending on the American Collage of Rheumatology (ACR) criteria at the same time or after the diagnosis of SLE. Headache classification was done regarding the ICD-II criteria in the patients. Headache severity was assessed by visual analog scale (VAS), and subjects with VAS > or = 4 were included in the study. Patients were divided into two groups according to magnetic resonance imaging (MRI) findings: abnormal MRI (lesion positive) and normal MRI (lesion negative). On MRI, intracranial lesions were detected in 37.5% (n = 18) of the patients, and no lesion was found in 62.5% (n = 30). Headache characteristics were as tension type in 54.1% (n = 26) and migraine like in 39.6% (n = 19) of all patients. Imaging findings were mostly as periventricular and subcortical focal lesions, ranging from 3-22 mm in diameter. A significant correlation was found between abnormal MRI findings with advanced age and prolonged disease duration (p = 0.018, p = 0.016)., Conclusions: As a conclusion, a detailed neurologic evaluation and radiologic investigation, if necessary, should be performed in SLE patients with prolonged disease and advanced age, regardless of headache characteristics.

- Abstract
Headache is one of the most common neurological complaints of the young population and it affects the quality of life due to limitation of daily activities. In this study, our main goal was to appraise the general headache characteristics in senior medical students just before graduation and to determine the impact of headache on the quality of life, as well as the general attitude of students about their headaches. The study group consisted of 141 senior students. As the first step, the question about "having headache within the past one year period" was asked. Of the 141 students, 127 students answering "yes" were invited to a face-to-face interview. Of these, 67 students (52.8%) participated in the second evaluation. The second evaluation consisted of history taking and neurological and physical examination. All subjects were classified according to the International Classification of Headache Disorders (2nd edition) criteria. Validated Turkish version of Migraine Disability Assessment questionnaire was given to the subjects to evaluate the socio-economical impact of headache. Tension-type headache, which is the most common form of primary headaches, was identified in 34 students (50.7%) out of 67 students. Migraine was detected in 31 students (46.3%). This is the first study performed on a face-to-face interview basis with medical students using the new classification criteria in Turkey. Astonishingly, most of the students (n:65) ignored their headaches and did not seek medication, despite the negative impact of headache on daily functioning and overall quality of life.

- Abstract
We report on the development of transient parkinsonism after progesterone injection in a pregnant patient with a risk of abortion. Etiological possibilities are discussed, including pregnancy itself, possible toxic effects of the dead fetus, and progesterone injection. Progesterone-induced parkinsonism seems the most likely diagnosis in this case.
