The role of oligoclonal band count and IgG index in treatment response and disease activity in multiple sclerosis.

BACKGROUND/AIM: Multiple sclerosis (MS) is an inflammatory demyelinating central nervous system (CNS) disease. Among the paraclinical tests, brain and spinal Magnetic Resonance Imaging (MRI) is primarily involved in the diagnosis process, and cerebrospinal fluid (CSF) analysis is fundamental in diagnosing MS and the differential diagnosis. A positive relationship was demonstrated between oligoclonal band (OCB) positivity, CSF band number and immunoglobulin G(IgG) index. The study aimed to evaluate whether the number of OCB can predict disease activity and determine a correlation with the IgG index. METHODS: Our study included 401 MS patients who had relapsing-remitting multiple sclerosis (RRMS), primary progressive multiple sclerosis (PPMS), secondary progressive multiple sclerosis (SPMS), clinic isolated syndrome (CIS), radiologic isolated syndrome (RIS), Neuromyelitis optica spectrum disorder (NMOSD) and Acute disseminated encephalomyelitis (ADEM) with OCB number groups of 2-4, 4-8, 8-12, and 12 and above. RESULTS: No significant correlation was observed between IgG index, pre-and post-treatment EDSS (Expanded Disability Status Scale Scores) and disease-modifying therapies (DMT). Drug response was better in the patient group with band number between 2 and 8 and post-treatment EDSS scores were lower (1.62±0.44). CONCLUSION: The study results suggested that band number may be as valuable as the IgG index and a predictive biomarker for disease activity.

Retrospective analysis of effectiveness of fingolimod in real life setting in Turkey (REFINE).

BACKGROUND: During multiple sclerosis (MS) treatment different modes of action such as lateral (interferon beta to glatiramer acetate or glatiramer acetate to interferon beta) or vertical (interferon beta/glatiramer acetate to fingolimod) drug switch can be performed. This study aims to investigate the clinical effectiveness of switching from the first-line injectable disease modifying treatments (iDMTs) to fingolimod (FNG) compared to switching between first-line iDMTs. METHODS: This is a multicenter, observational and retrospective study of patients with relapsing-remitting MS who had lateral and vertical switch. The observation period included three key assessment time points (before the switch, at switch, and after the switch). Data were collected from the MS patients' database by neurologists between January 2018 and June 2019. The longest follow-up period of the patients was determined as 24 months after the switch. RESULTS: In 462 MS patients that were included in the study, both treatments significantly decreased the number of relapses during the postswitch 12 months versus preswitch one year while patients in the FNG group experienced significantly fewer relapses compared to iDMT cohort in the postswitch 12 months period. FNG cohort experienced fewer relapses than in the iDMT cohort within the postswitch 2 year. The mean time to first relapse after the switch was significantly longer in the FNG group. DISCUSSION: The present study revealed superior effectiveness of vertical switch over lateral switch regarding the improvement in relapse outcomes. Patients in the FNG cohort experienced sustainably fewer relapses during the follow-up period after the switch compared the iDMT cohort. Importantly, switching to FNG was more effective in delaying time to first relapse when compared with iDMTs.

Combined progressive functional exercise effect on contactin-1 and contactin-2 level in mildly disabled persons with multiple sclerosis.

BACKGROUND: Although contactin-1 and contactin-2 are known as two proteins involved in axonal regeneration, it is unclear whether these proteins are induced by exercise in persons with multiple sclerosis (PwMS). OBJECTIVE: The aim of this study was to determine the serum levels of contactin-1 and contactin-2 in PwMS and to investigate the change of these markers with exercise. METHODS: A total of 60 participants with relapsing-remitting MS were divided into groups by stratified randomization. The progressive functional exercise was applied to the intervention group. Participants in the control group continued the treatments and lives of the routines. Participants' contactin-1 and contactin-2, cognitive performance and aerobic capacities were evaluated. RESULTS: The comparison of the pre-and post-study values of contactin-1 and contactin-2 showed significant differences only in the intervention group. The contactin-1 and contactin-2 values were similar between the groups before the exercise, whereas a significant difference was found in favor of the intervention group after the exercise. Paced Auditory Serial Addition Test-3 value increased significantly only in the intervention group. CONCLUSION: With this study, it was shown for the first time that contactin-1 and contactin-2, which play an important role in axonal regeneration and axonal organization, can be increased by exercise.

Evaluation of neurological disorders that develop concurrently with COVID-19 pneumonia: a retrospective analysis.

BACKGROUND: During the pandemic, many neurological symptoms have been evaluated as complications of COVID-19 pneumonia. OBJECTIVE: To investigate the frequency and characteristics of neurological findings, and their effects on the prognosis of patients with COVID-19 pneumonia who consulted with the Neurology department. METHODS: Data on 2329 patients who were hospitalized with the diagnosis of COVID-19 pneumonia in our hospital were scanned. The clinical, laboratory and radiological findings relating to treatment of 154 patients who required neurological consultation were retrospectively evaluated by reviewing the clinical notes. RESULTS: The number of COVID-19 pneumonia patients who required neurological consultations while hospitalized in the ICU was 94 (61.0%). The most common symptom among these patients was hyperactive delirium. Mean age, ferritin levels and CRP values ​​of those with delirium were higher, while the mean lymphocyte percentage were lower, than those of the patients without delirium. Epileptic seizures were observed in eight patients without an epilepsy diagnosis. Two patients were diagnosed with GBS and one patient with ICU neuropathy. The D-dimer levels of patients with acute hemorrhagic CVD and the thrombocyte levels of patients with acute ischemic CVD were found to be higher than in patients without acute ischemic CVD. CONCLUSION: The proportion of patients who required neurological consultations was higher in the ICUs. We observed neurological symptoms more frequently in the advanced age group. There were no significant increases in the incidence of other neurological conditions except delirium, in COVID-19 patients. We think that further studies are needed to support our data.

RESUMO Antecedentes: Durante a pandemia, muitos sintomas neurológicos foram avaliados como complicações da pneumonia por COVID-19. Objetivo: Investigar a frequência e as características dos achados neurológicos e seus efeitos no prognóstico de pacientes com pneumonia por COVID-19 que consultaram o departamento de Neurologia. Métodos: Foram analisados os dados de 2.329 pacientes internados com diagnóstico de pneumonia por COVID-19 em nosso hospital. Os achados clínicos, laboratoriais e radiológicos relativos ao tratamento de 154 pacientes que necessitaram de consulta neurológica foram avaliados retrospectivamente por meio da revisão das anotações clínicas. Resultados: O número de pacientes com pneumonia por COVID-19 que necessitaram de consultas neurológicas enquanto internados na UTI foi de 94 (61,0%). O sintoma mais comum entre esses pacientes foi o delírio hiperativo. A média de idade, os níveis de ferritina e os valores de PCR daqueles apresentando delírios foram maiores, enquanto a porcentagem média de linfócitos foi menor do que em pacientes sem delírios. Crises epilépticas foram observadas em oito pacientes sem diagnóstico de epilepsia. Dois pacientes foram diagnosticados com SGB e um paciente com neuropatia na UTI. Os níveis de dímero D de pacientes com DCV hemorrágica aguda e os níveis de trombócitos de pacientes com DCV isquêmica aguda foram maiores do que em pacientes sem DCV isquêmica aguda. Conclusão: A proporção de pacientes que necessitaram consultas neurológicas foi maior nas UTIs. Observamos sintomas neurológicos com mais frequência em pacientes de faixa etária avançada. Não houve aumentos significativos na incidência de outras condições neurológicas, exceto delírio, em pacientes com COVID-19. Acreditamos que mais estudos são necessários para apoiar nossos dados.

Aerobic exercise increases irisin serum levels and improves depression and fatigue in patients with relapsing remitting multiple sclerosis: A randomized controlled trial.

BACKGROUND: Multiple sclerosis (MS) is a chronic progressive neurodegenerative disease of the central nervous system. Although there is increasing evidence that aerobic exercise has a positive effect on both cognitive and psychological functioning, there is limited evidence for Relapsing-Remitting MS (RRMS) patients. Moreover, it is unclear at what exercise modality and intensity the irisin, the cleaved and circulating form of the exercise-associated membrane protein Fibronectin Type III Domain Containing 5, is induced in patients with MS. This study aimed to investigate the effect of a regular aerobic exercise program on irisin serum level, depression, fatigue, and cognitive performance in patients with MS. METHODS: Thirty-two individuals with RRMS were randomized into 2 groups as control and study groups (mean EDSS score 1.69 and 1.97, respectively). While the Study Group received a combined exercise training consisting of three sessions of aerobic exercise and Frenkel Coordination Exercises per week for 6 weeks, the Control Group received only Frenkel Coordination Exercise training. Before and after the study, the cognitive performance of the participants were evaluated with the Paced Auditory Serial Addition Test with 3-second stimulus (PASAT-3), their maximum aerobic capacity with the Fitmate Pro® (VO2max), their fatigue status with the Fatigue Impact Scale (FIS), and their depression status with the Beck Depression Inventory (BDI). Irisin serum levels were analyzed with Enzyme-Linked ImmunoSorbent Assay (ELISA) test from the serum samples of individuals. RESULTS: Our results revealed that the irisin serum level significantly increased in the Study Group. Significant improvement in aerobic capacity, PASAT-3, FIS, and BDI values was observed in the Study Group compared to the Control Group. When the ΔIrisin, ΔVO2max, ΔFIS, and ΔBDI values between the groups were compared, a significant difference was found in favor of the study group. CONCLUSION: The aerobic exercise revealed significant changes in depression, fatigue and irisin serum levels in MS patients. We think that this study, in which a significant increase in irisin serum level, significant improvement in depression, cognitive performance and fatigue states were obtained in the Study Group, will be a pioneering study for the future studies aiming to investigate the effects of irisin serum level on these symptoms in detail.

Physical exercise may improve problem-solving skills and emotional intelligence in patients with relapsing-remitting multiple sclerosis: A cross-sectional study.

BACKGROUND: Multiple sclerosis is a disease that can reduce the quality of life with a physical disability, neuropsychiatric disorders, and cognitive dysfunctions. Therefore, multiple sclerosis treatment should include treatments for cognitive and neuropsychiatric disorders and pharmacological treatments. This study aimed to examine the effects of exercise on neuropsychiatric disorders, problem-solving skills, and emotional intelligence in multiple sclerosis patients. METHODS: Thirty-six female relapsing-remitting multiple sclerosis patients aged between 18 and 45 years, with an Expanded Disability Status Scale between 1 and 3, who were diagnosed with definitive multiple sclerosis according to the revised McDonald criteria were included in the study. Participants completed outcome measures before and after the 12-week exercise program. Demographic/clinical information of the participants was obtained at baseline, neurological examinations were performed, and graded exercise testing on a bicycle ergometer was performed to determine aerobic capacity. Short Form-12 Version 2, Hospital Anxiety and Depression Scale, Modified Fatigue Impact Scale, Problem-Solving Inventory, Emotional Intelligence Scale were evaluated before and after the exercise program of the participants. RESULTS: While a significant increase was observed in the HRpeak values ​​of the participants after the exercise (p < 0.05), the VO2max values also showed a highly significant difference compared to the pre-treatment values. (p < 0.01). While a significant difference was detected in the mental subparameter of Short Form-12 (p < 0.05), a high level of significant difference was found in the physical subparameter (p < 0.01). While no significant difference was observed in the Hospital Anxiety and Depression Scale anxiety subparameter (p > 0.05), a significant difference was found in the depression subparameter (p < 0.01). There was a significant difference in Modified Fatigue Impact Scale physical and cognitive subparameters compared to pre-treatment (p < 0.01). A significant difference was observed in the Emotional Intelligence Scale total score after the treatment (p < 0.01). CONCLUSIONS: The results of our study showed that exercise in relapsing-remitting multiple sclerosis patients provided significant improvements in emotional intelligence, improved neuropsychiatric parameters, and increased problem-solving skills. In addition, to the best of our knowledge, this study is the first study in the literature to investigate the effect of physical activity exercises on problem-solving skills in multiple sclerosis patients.

Validity and reliability of the 3-meter backward walk test in mildly disabled persons with multiple sclerosis.

BACKGROUND: One of the biggest problems for persons with Multiple Sclerosis (PwMS) is dizziness, poor posture, and balance problems that cause injury-causing falls. The aim of our study was to reveal the test-retest reliability and validity of the 3-Meter Backward Walk Test (3MBWT) in mildly disabled PwMS. METHODS: This study included a total of 93 mildly disabled PwMS with mean EDSS of 1.89. 3MBWT, Functional Access Test (FRT), Dynamic Gait Index (DGI), Timed 25-Foot Walk (T25FW), and Timed-Up and Go (TUG) were applied to the patients. To measure test-retest reliability, a second evaluation was performed three days after the first evaluation. RESULTS: Cronbach's alpha coefficient was found to be 0.998 (excellent). For intra-rater agreement, the ICC values in the individual test were 0.998. The SEM value was 0.18, the MDC value was found to be 0.50. A very strong correlation was revealed between the 3MBWT and FRT (r: -0.931, p: 0.001), TUG (r: 0.968, p: 0.001), T25FW (r: 0.879, p: 0.001), DGI (r: -0.871, p: 0.001) and falling history (r: 0.932, p: 0.001). CONCLUSION: The 3MBWT was observed to be valid and reliable in mildly disabled PwMS. 3MBWT is an effective and reliable tool for measuring ability to walk backward in mildly disabled PwMS.

Restless legs syndrome affecting the head region: "restless head syndrome".

OBJECTIVE: Restless legs syndrome (RLS) is a well-established disease that has recently been shown to have variants affecting the arms, face, abdomen, and genital area. To our knowledge, there has been no study reporting on the RLS variant affecting the head region. METHODS: The retrospective study reviewed a total of 460 patients who presented to Firat University Medical School and were diagnosed as having RLS based on the International Restless Legs Syndrome Study Group (IRLSSG) criteria between June 2017 and January 2020. Of these, 18 patients that presented with head-related RLS symptoms (in addition to legs or arms) and four cases that presented with isolated head involvement were included in the study. RESULTS: In 15 out of 18 (81.8%) patients, the restless head syndrome was accompanied by restless arm syndrome (RAS). In the remaining four (18.2%) patients, the disease involved the head region alone. The disease initially emerged in a single region in the body and gradually spread to one or multiple other regions in most patients and the symptoms were relieved by head rubbing. Serum iron level was low in 8 (36.4%) patients and normal in 14 (63.6%) patients. All the patients had normal cranial imaging and the symptoms were eliminated after dopaminergic therapy. CONCLUSIONS: Although RLS typically involves the legs alone, it may also affect other body parts such as upper extremities, abdomen, face, and genital area. We propose that the novel RLS variant described in the present study could be termed "restless head syndrome."

Positive effects of ocrelizumab in patients with familial mediterranean fever and coexistent multiple sclerosis.

OBJECTIVES: This study aims to evaluate the effects of ocrelizumab (OCZ) on familial Mediterranean fever (FMF) attacks in multiple sclerosis (MS) patients with FMF (MS+FMF patients). PATIENTS AND METHODS: This retrospective observational study included 11 patients (2 males, 9 females; mean age 46.6±9.2; range, 22 to 55 years) with MS+FMF hospitalized between January 2016 and July 2019. Demographic, clinical, and laboratory parameters and patient reported outcomes were analyzed in patients treated with OCZ for 18 months. RESULTS: Combining OCZ with colchicine in MS+FMF patients significantly reduced the frequency of FMF attacks (p=0.003) and the frequency of joint attacks (p=0.002). Consistent with the clinical improvement, the maximum serum C-reactive protein levels were significantly decreased after combination therapy compared to before combination therapy (p=0.003). MS+FMF patients reported that FMF disease activity improved after OCZ therapy (Visual Analog Scale [VAS] 74±9.6 vs. VAS 46.5±8.1 mm, p=0.003). CONCLUSION: Ocrelizumab therapy led to a prominent decrease in the frequency of FMF attacks, alleviated functional impairment, and improved quality of life in MS+FMF patients.

Detection of ataxia in low disability MS patients by hybrid convolutional neural networks based on images of plantar pressure distribution.

BACKGROUND: This study aimed to detect ataxia in patients with multiple sclerosis (PwMS) with a deep learning-based approach based on images showing plantar pressure distribution of the patients. The secondary aim of the study was to investigate an alternative and objective method in the early diagnosis of ataxia in these patients. METHODS: A total of 105 images showing plantar pressure distribution of 43 ataxic PwMS and 62 healthy individuals were analyzed. The images were resized for the models including VGG16, VGG19, ResNet, DenseNet, MobileNet, NasNetMobile, and NasNetLarge. Feature vectors were extracted from the resized images and then classified using Support Vector Machines (SVM), K-Nearest Neighbors (K-NN), and Artificial Neural Network (ANN). A 10-fold cross-validation was applied to increase the validity of the classifiers. RESULTS: The VGG19-SVM hybrid model showed the highest accuracy, sensitivity, and specificity values (89.23%, 89.65%, and 88.88%, respectively). CONCLUSION: The proposed method provided an automatic decision support system for detecting ataxia based on images showing plantar pressure distribution in patients with PwMS. The performance of the proposed method indicated that this method can be applied in clinical practice to establish a rapid diagnosis of ataxia that is asymptomatic or difficult to detect clinically and that it can be recommended as a useful aid for the physician in clinical practice.

The effect of aerobic exercise on Neurofilament light chain and glial Fibrillary acidic protein level in patients with relapsing remitting type multiple sclerosis.

Background Multiple sclerosis (MS) is an autoimmune and neurodegenerative disease of the central nervous system in which disease activity can be monitored with some biomarkers. The aim of our study was to investigate serum Glial Fibrillary Acidic Protein (GFAP) and Neurofilament Light Chain (NFL) in relapsing-remitting MS (RRMS) patients after the aerobic exercise. Methods A total of 38 participants with RRMS (Expanded Disability Status Scale: 1.0 - 4.5) were randomized to a study group (3 × /week for 8 weeks at 60 - 70 % of maximal aerobic capacity (VO2max) + home exercises) and a control group (were given home exercises programme 3 times a week for 8 week). Serum NFL and GFAP levels were analyzed using enzyme-linked immunosorbent analysis method before and at the end of 8 weeks. Results: NFL and GFAP levels were statistically lower in the study group at the end of the study than before the study. In the control group, no significant changes were observed in serum NFL and GFAP levels. ΔNFL levels were significantly higher in the study group than control group. Conclusion It was shown, for the first time that serum GFAP and NFL levels (%10 and % 32, respectively) in RRMS patients decreased after aerobic exercise. Our study is important in terms of investigating the effects of aerobic exercise in individuals with RRMS and elucidating the underlying measurable biomarkers. The significant reduction of NFL and GFAP, which have an important role in the pathology associated with nervous system damage in MS, with aerobic exercise may be promising in understanding the regulation of disease activity in MS patients.

A case of syncopal convulsions triggered by glossopharyngeal neuralgia.

Syncopal convulsions and epileptic seizures are clinically hard to distinguish and differ in terms of treatment approaches. It is important to consider the cardiac arrhythmias that impair cerebral perfusion in the differential diagnosis of antiepileptic treatment-resistant convulsions. Here we offer a 72 year old male patient glossopharengial neuralgia after swallowing associated with recurrent episodes of syncopal convulsions. The patient was successfully treated with temporary pacemaker and carbamazepine. This phenomenon is noteworthy in terms of both asystole triggered by glossopharengial neuralgia and syncopal convulsions which are rare in the differential diagnosis of epileptic seizures.

Increased serum chemerin levels associated with carotid intima-media thickness.

BACKGROUND: Elevated levels of chemerin can predict future ischemic cerebrovascular disease. Although chemerin is thought to play a role in atherosclerotic inflammation, whether circulating chemerin levels are associated with the severity of atherosclerosis remains to be determined. OBJECTIVES: Through the use of carotid Doppler ultrasonography, our aim in this study was to investigate the relationships of serum chemerin levels with carotid intima-media thickness (CIMT) as an indicator of generalized atherosclerosis. METHODS: This study compared 40 patients with ischemic stroke and 40 healthy subjects. Measurements were made at end-diastole using color Doppler ultrasonography (CDUS) after a 5-min rest interval in a quiet and dark room. CIMT was defined as the distance between the innermost edge of the luminal echo to the innermost edge of the media/adventitia echo. CIMT was measured in the posterior wall of both common carotid arteries within 1 cm proximally to the bulbus. Three measurements were made on both sides and the average measurement was taken as the CIMT. Serum chemerin levels were determined in all patients and healthy subjects. RESULTS: Serum chemerin levels were significantly higher in the patient group than in the control group (p=0.004). Serum chemerin levels were positively correlated with CIMT (p<0.05). There was a significant difference between the groups with regard to CIMT (p<0.001). CONCLUSION: Elevated serum chemerin levels appear to be associated with CIMT, thus suggesting that a link exists between chemerin and atherosclerotic ischemic cerebrovascular disease.

RESUMO Introdução: Níveis elevados de chemerin podem prever doenças cerebrovasculares isquêmicas futuras. Embora se acredite que a chemerin desempenhe um papel na inflamação aterosclerótica, ainda não foi determinado se os níveis circulantes de chemerin estão associados à gravidade da aterosclerose Objetivos: Por meio do uso da ultrassonografia Doppler da carótida, nosso objetivo neste estudo foi investigar as relações dos níveis séricos de chemerin com a espessura da íntima-média da carótida (EIMC) como um indicador de aterosclerose generalizada. Métodos: Este estudo comparou 40 pacientes com AVC isquêmico e 40 indivíduos saudáveis. As medidas foram feitas no final da diástole usando ultrassonografia Doppler em cores (USDC), após um intervalo de descanso de 5 minutos em um quarto silencioso e escuro. A EIMC foi definida como a distância entre a borda mais interna do eco luminal e a borda mais interna do eco da mídia/adventícia. EIMC foi medido na parede posterior de ambas as artérias carótidas comuns dentro de 1 cm proximalmente ao bulbo. Três medições foram feitas em ambos os lados e a medição média foi tomada como o EIMC. Os níveis séricos de chemerin foram determinados em todos os pacientes e indivíduos saudáveis. Resultados: Os níveis séricos de chemerin foram significativamente maiores no grupo de pacientes do que no grupo controle (p=0,004). Os níveis séricos de chemerin foram positivamente correlacionados com EIMC (p<0,05). Houve diferença significativa entre os grupos em relação à EIMC (p<0,001). Conclusão: Níveis séricos elevados de chemerin parecem estar associados com a EIMC, sugerindo que existe uma ligação entre chemerin e doença cerebrovascular isquêmica aterosclerótica.

S100B and neuron-specific enolase levels in episodic and chronic migraine.

OBJECTIVES: In recent years, radiological and biochemical data have emerged regarding the development of cellular damage in the brain of patients with migraine, calling into question what has traditionally been accepted as a benign disorder. In order to investigate whether cellular damage develops in the brain of episodic migraine patient, serum levels of neuron-specific enolase (NSE) and S100B have been evaluated in recent studies. However, contradictory results were obtained in these studies. Moreover, there is no study on NSE and S100B in cases of chronic migraine. METHODS: Patients with episodic migraine with or without aura and chronic migraine were included. In addition, 27 healthy volunteers were included as a control group. Control group was selected from healthy volunteers of the same age and sex. We investigated serum NSE and S100B levels during the interictal period in 26 patients with episodic migraine and 27 patients with chronic migraine. RESULTS: The serum NSE and S100B levels were significantly higher in both patients with episodic and chronic migraine than controls. Although there were no significant differences in the serum NSE and S100B levels between the two patients' groups, these markers were found to be higher in cases of chronic migraine. CONCLUSION: These results suggest that there is both neuronal and glial involvement in the two migraine groups. Elevations in these markers in cases of episodic migraine suggest that cellular damage not only results from headache episodes, but that there may be also an ongoing pathological process during the interictal period.

Neuropsychiatric changes during the COVID-19 pandemic in multiple sclerosis patients.

BACKGROUND: This study reported on a variety of psychological reactions related to anxiety, sleep quality, depression, fatigue, and quality of life in individuals with multiple sclerosis (MS), related to the Covid-19 quarantine experience. OBJECTIVE: The aim of this study was to investigate the neuropsychiatric effects of the COVID-19 pandemic in MS patients and to analyze the risk factors contributing to psychological stress. METHODS: The study was designed as a prospective, cross-sectional survey study. Multiple assessment tools that are used in neurological practice, including Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), Fatigue Impact Scale (FIS), Pittsburgh Sleep Quality Index (PSQI), and Multiple Sclerosis Quality of Life-54 (MSQOL-54) were administered prospectively both during the early and the peak stages of COVID-19 outbreak (ESO and PSO, respectively). The survey forms were designed using SurveyMonkey and the participants were participating in the survey via a web link and QR code. RESULTS: Fifty patients were included in the study. BDI scores, PSQI and FSI measurements, cognitive and social subscale scores and total FIS score, MSQOL-54 measurements, physical and mental subscale scores, and total MSQOL-54 score at PSO were significantly different than those at ESO. The body mass index values of the patients increased significantly at PSO compared to those measured at ESO. CONCLUSIONS: The results provide a basis for the development of psychological interventions that could minimize the prevalence of sleep disorders and depression and could improve patients' quality of life during the outbreak.

Analysis of Childhood Traumas and Defense Styles in Patients With Tension Headache.

OBJECTIVE: Studies indicate that patients tend to develop chronic tension headache as a response to stress. The present study investigated the relationship between headache and the events that caused childhood traumas and defense styles, which could be considered as a significant source of stress in individuals with tension headache. METHODS: Fifty patients between the ages of 18 and 65 years diagnosed with tension headache were included in the present study. The control group included 50 healthy participants. All study participants completed a sociodemographic data form prepared by the researchers and the Childhood Trauma Questionnaire and Defense Style Questionnaire. RESULTS: Traumatic experiences (emotional abuse, physical abuse, emotional neglect, physical neglect, and sexual abuse) were significantly higher in the patient group compared to the control group. The total score of immature and neurotic defense styles was higher in the patient group than in the control group (P < .001, P < .001). The mature defense styles total score was significantly higher in the control group than in the patient group (P = .006). A positive correlation was found between the childhood trauma scores and immature and neurotic defense style scores. CONCLUSION: The findings indicate that traumatic experiences during childhood were more frequent in patients with tension headache compared to healthy individuals. Furthermore, these individuals had difficulty coping with stress, and inappropriate defense styles were employed as a response to stress.

Suboccipital steroid injection alone as a preventive treatment for cluster headache.

BACKGROUND: Suboccipital steroid injection can be used as a preventive treatment for episodic and chronic cluster headache (CH). In recent studies, prophylactic treatment has been used in addition to suboccipital steroid injection. In this study, we aimed to investigate the effectivity of the sole use of rapid- and long-acting steroid injections without prophylactic treatment in patients with episodic and chronic CH. METHODS: The retrospective study included 51 patients with episodic and chronic CH that underwent greater occipital nerve (GON) blockade with a single dose of rapid- and long-acting steroid injection without additional prophylactic treatment. The frequency, severity, and duration of attacks after GON blockade as well as the side effects and long-term outcomes were reviewed. RESULTS: In 28 (54.9%) patients, no attack occurred after GON blockade and cluster bouts were aborted. Mean duration of attacks was 86.67 ±â€¯37.45 min before the treatment. However, in the 23 patients that had at least one attack after GON blockade, the mean duration of attacks was 31.73 ±â€¯36.10 min between post-treatment days 0-3, 29.35 ±â€¯40.49 min between post-treatment days 4-10, 28.48 ±â€¯42.17 min between post-treatment days 11-28, and 35.65 ±â€¯46.55 min after the post-treatment day 28 (p < 0.001). Moreover, 10 (37.04%) out of 27 patients with episodic CH who periodically had one or two cluster bouts in a year had no CH attack at the time of the expected subsequent cluster bout. CONCLUSION: GON blockade is a practical, reliable, and cost-effective treatment option for patients with episodic and chronic CH. Moreover, GON blockade is highly effective in reducing headache attacks and even aborting cluster bouts in CH patients without requiring additional prophylactic treatment.
