Eating attitudes of migraine patients in Turkey: a prospective multi-center study.

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.

[Assessment of serum MMP-9, TIMP-1 levels and MMP-9/TIMP-1 ratio in migraine patients with and without aura].

Background and purpose: Matrix metalloproteinases (MMP) are the enzymes responsible for proteolytic ac-tivity of extracellular matrix proteins. Tissue inhibitors of metalloproteinases (TIMPs) are their endogenous inhibitors. MMP-9 acts on the basal membrane of cerebellar epithe-lium and is antagonized by TIMP-1. MMP-9/TIMP-1 ratio exhibits the net activity of MMP-9. These enzymes are thought to have a role in migraine physio-pathogenesis. Methods: Total of 50 treatment-naive migraine patients (25 with aura and 25 without aura) with no other diseases, were included. 25 healthy control subjects of cor-responding age and gender were enrolled. For MMP-9 and TIMP-1 analysis, one serum sample from control group and two samples from patients were collected (during headache and headache-free periods). The enzyme levels were quantitatively analyzed by competitive ELISA method. Duration and severity of the pain and duration of the disease were recorded. Results: There was no significant difference in MMP-9 levels between patient and control groups during headache and headache-free periods (p: 0,746, p: 0,243). TIMP-1 levels were significantly lower and MMP-9/TIMP ratios were higher comparing with the control group (p: 0.001). Positive correlation was obtained between the duration of pain and MMP-9 levels in the headache-free period for both patient groups (p<0.05). There was also a positive correlation between MMP-9/TIMP-1 ratio and severity of pain (p<0.05). Conclusion: In our study, low TIMP-1 levels of patients in both headache and headache-free periods suggest that disturbance of proteolytic protection has a role in neuro-inflammation and pain in migraine. Therefore, these enzymes could be potential targets in migraine therapies.

Evaluation of interictal autonomic function during attack and remission periods in cluster headaches.

OBJECTIVE: To investigate which part of the autonomic system is mainly involved and assess the sensitivity of face sympathetic skin response in cluster headache. MATERIAL AND METHODS: The study sample consisted of 19 drug-free cluster headache patients (16 males, three females) and 19 healthy volunteers. Demographic features and pain characteristics were thoroughly identified. Dysautonomic symptoms were evaluated during attack and remission periods of cluster headache patients. Orthostatic hypotension, R-R interval variation and sympathetic skin responses obtained from the face and four extremities were evaluated and the sensitivity of face sympathetic skin responses was assessed in contrast to extremity sympathetic skin responses. RESULTS: All sympathetic skin responses of face and extremities could be obtained during attack and remission periods. On the symptomatic side, mean latency of face sympathetic skin responses was longer compared to the asymptomatic side and controls (p = 0.02, p = 0.004). There were no differences in latency or amplitude of extremity sympathetic skin responses between symptomatic and asymptomatic sides and controls. No significant relationship was determined between sympathetic skin responses, R-R interval variation, orthostatic hypotension and cluster headache clinical features. CONCLUSION: Sympathetic hypoactivity of the face seems to predominate the pathophysiology of cluster headache. Face sympathetic skin responses might be more sensitive compared to extremity sympathetic skin response in demonstrating dysautonomic symptoms in cluster headache patients.

The relation of serum uric acid levels with L-Dopa treatment and progression in patients with Parkinson's disease.

In this study, we aimed to investigate the association of the serum uric acid (UA) level with disease progression and L-Dopa treatment in PD (Parkinson's disease) patients. Serum UA levels of 80 consecutive PD patients were measured and were matched according to age and sex with 80 healthy controls. The patients were divided into two subgroups according to the pharmaceutical treatment received. First group consisted of patients treated with L-Dopa and a dopamine agonist and the second group consisted of patients treated only with a dopamine agonist. The patients were divided into two other subgroups according to Hoehn and Yahr scale. First group consisted of patients at the first two stages and the second group included patients at the third and upper stages. PD patients were found to have significantly lower levels of serum UA than controls (p = 0.000). Serum UA levels were lower in the group under L-Dopa + dopamine agonist treatment and in patients at third and upper Hoehn and Yahr stages than the patients under only dopamine agonist treatment and in the patients at the first two stages (p = 0.000 and p = 0.000). Multivariate logistic regression showed that advanced stages (OR 0.65, CI 0.50-0.79, p = 0.000) and L-Dopa treatment (OR 1.08, CI 1.03-1.16, p = 0.001) were independently associated with low UA levels. Our study supports that there is an inverse relation between UA levels and L-Dopa treatment and PD stages, and high serum UA levels may decrease the oxidative stress taking part in the pathogenesis of PD.

Chronic manganese toxicity due to substance abuse in Turkish patients.

BACKGROUND: Manganese toxicity may lead to a levodopa-resistant akinetic-rigid syndrome. Pathological changes occur mostly in the pallidium and stratium. MATERIALS AND METHODS: We report seven patients with a new form of chronic manganese toxicity due to long-term intravenous use of a solution consisting of ephedrine, acetylsalicylic acid and potassium permanganate as a psycho-stimulant, popularly known as "Russian Cocktail". RESULTS: The age of the patients ranged between 19 and 31 years, and the duration of substance abuse was between nine and 106 months. The onset of symptoms from first use ranged seven to 35 months. The initial symptom was impaired speech followed by gait disturbance and bradykinesia. In addition to these symptoms, choreic movements, ataxia presenting as backward falls and dystonia were also seen. Serum and urine samples revealed high levels of manganese. Hyperintense lesions on T1-weighted magnetic resonance imaging were seen in bilateral basal ganglia and brainstem, dentate nuclei, features consistent with manganese intoxication. CONCLUSION: Manganese toxicity, which may cause a distinctive irreversible neurodegenerative disorder, can be seen frequently with "Russian Cocktail" abuse, a substance which can be accessed very easily and at a low cost.

A Case of Acute Intermittent Porphyria Mimicking Guillain-Barré Syndrome.

Patients with acute intermittent porphyria attacks present with severe abdominal pain, neuropathy and psychiatric disturbances. Porphyric neuropathy mostly causes confusion in clinical practice, and patients with porphyria are rarely correctly diagnosed early in the course of the illness. We report a patient with acute intermittent porphyria mimicking Guillain-Barré syndrome with acute onset weakness that rapidly progressed to severe quadriplegia.

Blink Reflex in Episodic and Chronic Migraine.

INTRODUCTION: Activation of the trigeminovascular system and sensitization of brainstem trigeminal nuclei play a significant role in the physiopathology of migraine. Our aim was to investigate blink reflex (BR) and its recovery in episodic and chronic migraine patients. METHODS: Twenty-eight chronic migraine patients, thirty-two episodic migraine without aura patients and thirty healthy controls were included in the study. The study was performed using a portable electromyography device with a software specifically prepared for BR. Blink reflex assessments were performed in patients during the pain-free period and in healthy controls using the 'standard method - double stimulation' technique in 200 ms, 500 ms, 1000 ms, 2000 ms, and 5000 ms intervals. RESULTS: Blink reflex recovery was significantly increased in both patient groups as compared to the control group in 200 ms interstimulus interval (ISI) on both sides (p<0.005). Moreover, when it was compared to the control group, recovery was also significantly increased in the chronic migraine group in 2000 ms ISI on the right side and in 5000 ms ISI on the left side as well as in 500 and 1000 ms ISIs on the left side in the migraine without aura group (p<0.002, p<0.003). R2 recovery curve was noted to be higher in both patient groups as compared to the control group, although could not be demonstrated statistically in all intervals. A statistically significant increase was observed in the migraine group without auras compared with the controls (p <0,037, p <0,011) in the left side at 500 and 1000 ms ISIs. For all intervals in our study, although the increase in recovery was not statistically significant, it was noted that the R2 recovery curve was higher in the patient groups, with respect to the normals. The increase in R2 recovery noted in both patient groups suggested increased sensitization of the trigeminal structures. Significantly increased recovery in low ISI (200 ms) in the two patient groups as compared to the control group raised the thought that the migraine brain goes through two different excitability periods (ictal and interictal). CONCLUSION: In conclusion, similar to the previous studies, the findings of this study suggested that there was a reduction in central inhibitory mechanisms during interictal period in migraine patients.

Characteristics, diagnosis and outcome of patients referred to a specialized neurology emergency clinic: prospective observational study.

BACKGROUND: Organization and management of neurological emergencies differs among hospitals. Some have specialized neurological emergency rooms (ER). OBJECTIVES: The purpose of this study was to determine the characteristics, diagnosis and outcome of patients referred to a specialized emergency neurology clinic. DESIGN: Prospective, observational study of consecutive patients presenting between March 2014 and July 2014. SETTING: Neurologicaler of a training and research neuropsychiatric hospital. PATIENTS AND METHODS: Patients older than 16 years of age with a neurological complaint were assessed by neurological exam, laboratory and imaging tests including brain computed tomography (CT), brain magnetic resonance imaging (MRI), cerebrospinal fluid analysis, electroencephalography or electromyography. MAIN OUTCOME MEASURES: Types of diagnosis. RESULTS: Of 4500 patients, 2602 (57.8%) were female, and the mean age was 49.2 (23.6) years. The most common symptom was headache, which presented in 30.8% of all patients. The three most common diagnoses after emergency work-up were headache (27.8%), stroke (20.6%) and peripheral vertigo (13%). In the ER, CT was performed on 65.5% of patients and MRI on 66.9%. After emergency work-up, 72.2% patients were discharged home. CONCLUSIONS: Neurological diseases are common, with headache and cerebrovascular diseases being the most frequent diagnosis in this specialized ER. CT and MRI are most often used to diagnose or exclude neurological diseases. Many patients do not require immediate hospitalization. The two most frequent diagnoses for hospitalization were stroke and demyelinating disease. LIMITATIONS: Absence of follow up data on patients discharged home.

Ulnar nerve compression at the wrist: diagnostic role of palmar stimulation.

OBJECTIVE: Electrophysiological diagnosis of ulnar nerve entrapment at the wrist is sometimes difficult. The aim was to evaluate the diagnostic role of ulnar nerve stimulation above and below the Guyon channel in ulnar nerve entrapment at the wrist. METHODS: Supramaximal ulnar nerve stimulation at the wrist and palm, in addition to the standard nerve conduction studies, in 10 patients with ulnar nerve entrapment at the wrist and 40 controls. RESULTS: Motor latencies to the first dorsal interosseous muscle with wrist stimulation were prolonged unilaterally in six and bilaterally in four patients. Palmar stimulation showed partial conduction blocks on the more symptomatic side in all. In two bilateral cases, there were 28.8% and 44.3% amplitude loss on the less symptomatic side. Motor responses elicited with palm stimulation were also found to have prolonged latencies and decreased amplitudes. CONCLUSIONS: Stimulation of the deep branch of the ulnar nerve can expand the information about ulnar nerve entrapment at the wrist by providing evidence about its nature, prognosis, precise localization, and distal extent.
