An Unusual Cause of Internal Carotid Artery Dissection: Mobile Phone Misuse.

The use of mobile phones has become an indispensable part of our lives, especially due to widespread use of the internet. We report the case of a 38-year-old male patient who developed internal carotid artery dissection after talking on the phone between her left shoulder and ear by laterally flexing the neck for 20 minutes. In addition to many positive effects of technology that facilitate the daily life, the development of neurological deficits may be observed with widespread use of mobile phones. Misuse of mobile phone should be considered in patients with carotid artery dissection.

High-sensitivity C-reactive protein and high mobility group box-1 levels in Parkinson's disease.

Various immunologic and inflammatory factors are contributed to pathogenesis of Parkinson's disease (PD). High mobility group box-1 (HMGB1) is a protein that plays certain roles in inflammation, DNA repair, transcription, somatic recombination, cell differentiation, cell migration, neuronal development, and neurodegeneration. The aim of the present study was to evaluate the serum levels of HMGB1 and high-sensitivity C-reactive protein (hs-CRP) among patients with Parkinson's disease and healthy controls. This study includes 30 patients with PD and 30 healthy controls, matched sex, age, body mass index, and smoking status. HMGB1 and hs-CRP serum levels were compared between the groups. The diagnostic performance of HMGB1 and hs-CRP was evaluated with receiver operating characteristic (ROC) curve analysis. HMGB1 levels were significantly higher in PD patients than in controls. Hs-CRP levels were significantly higher in PD patients than in controls There was a moderate correlation between hs-CRP and HMGB1 levels in the patient group. The cut-off value of HMGB1 level for the prediction of PD was determined as 32.8 ng/mL with 80% sensitivity and 60% specificity (p = 0.006). The cut-off value of hs-CRP level for the prediction of PD was determined as 0.63 mg/L with 66.7% sensitivity and 77.7% specificity (p = 0.007). This study demonstrates for the first time the association between HMGB1, hs-CRP, and PD. We found that HMGB1 and hs-CRP levels to be significantly higher in the PD patients than in the normal controls. As a result of the ROC curve analysis, HMGB1 and hs-CRP levels may be fair markers in the diagnosis of PD.

Changes in serum albumin levels and neutrophil-lymphocyte ratio in patients with convulsive status epilepticus.

AIM: Inflammation may be involved in the ictogenesis and development of some partial epilepsies. Serum albumin levels and the neutrophil-lymphocyte ratio (NLR) are markers of inflammation. The aim of this study was to investigate the ability of serum albumin levels and NLR to predict inflammation in patients with convulsive status epilepticus (CSE). METHODS: This retrospective study was conducted on 58 patients who were diagnosed with CSE and control group comprised of 58 healthy individuals. Albumin levels and NLR were evaluated during both the acute and subacute periods of CSE. RESULTS: The average serum albumin levels were 3.27 ± 0.62 g/dL during the acute period and 3.4 ± 0.67 g/dL in the subacute period in the patient group and 3.92 ± 0.52 g/dL in the control group. Neutrophil counts were higher in patients in the acute phase of CSE, but lymphocyte counts were lower compared to the control group and the subacute phase. The average NLR values were 4.83 ± 5.1 in the acute period, 3.07 ± 3.02 during the subacute period and 1.98 ± 0.42 in the control group. Serum albumin and NLR levels were significantly different between the patients in the subacute and acute periods of CSE and the control group (p < 0.05). There were significant negative correlational relationships between serum albumin and NLR levels (p < 0.05). CONCLUSION: We found serum albumin levels were significantly lower and the NLR was significantly higher in the acute period of CSE. Neutrophil-mediated inflammation may be important in the aetiopathogenesis of CSE.

Evaluation of cerebral venous thrombosis secondary to oral contraceptive use in adolescents.

Our goal was to evaluate the clinical patterns, additional risk factors, treatment and outcome of cerebral venous thrombosis (CVT) related to adolescent oral contraceptive pill (OCP) usage. We evaluated 22 patients with CVT related to OCPs admitted to Firat and Dicle University Hospitals from January 2008 to January 2013. We assessed the clinical features, risk factors, imaging results and prognosis. Magnetic resonance imaging (MRI) and magnetic resonance were the preferred procedures for the diagnosis of CVT. MRI revealed parenchymal lesions in 11 (50 %) patients, and the remaining patients had normal MRIs. The sinuses most frequently affected by thrombosis were the superior sagittal sinus and the transverse sinus. The additional risk factors identified for CVT were antiphospholipid syndrome, protein C deficiency, protein C and S deficiency, factor V Leiden associated with heterozygous antithrombin III deficiency, methylenetetrahydrofolate reductase and prothrombin gene mutations. CVT may be overlooked in adolescents because it is more common among middle-aged and elderly adults. CVT should be suspected in the presence of neurological symptoms in adolescents, especially in those using OCPs.

The increase of carcinoembryonic antigen (CEA), high-sensitivity C-reactive protein, and neutrophil/lymphocyte ratio in Parkinson's disease.

The role of carcinoembryonic antigen (CEA) in Parkinson's disease (PD) has not been previously investigated. The aim of the present study was to evaluate the serum level of carcinoembryonic antigen, high-sensitivity C-reactive protein (hs-CRP), and Neutrophil/lymphocyte ratio (NLR) among patients with Parkinson's disease and to examine the relationship between these inflammatory markers. The cross-sectional design includes 51 patients with Parkinson's disease and 50 age- and sex-matched healthy controls. We investigated the differences in hs-CRP, CEA, and NLR levels between these two groups. CEA was significantly higher in PD patients relative to the control group (mean 2.40 ± 1.51 vs. 1.72 ± 0.87 (ng/mL), respectively; p = 0.015). Mean NLR was significantly higher in PD patients relative to the control group (mean 3.1 ± 1.3 vs. 2.1 ± 0.32, respectively; p < 0.001). Serum level of hs-CRP was higher in PD patients than in control group (mean 1.04 ± 0.62 and 0.54 ± 0.31, respectively; p < 0.01). Correlation analysis revealed significant correlation between hs-CRP, CEA, and Neutrophil/lymphocyte ratio (p < 0.05). This study demonstrates for the first time the association between CEA, hs-CRP, NLR, and PD. We found CEA, hs-CRP, and NLR levels to be significantly higher in the PD patients than in the normal controls.

Increased fibrinogen, D-dimer and galectin-3 levels in patients with migraine.

There are limited studies evaluating the fibrinogen levels in patients with migraine. It remains unknown whether the levels of the haematological marker of thromboembolism, D-dimer, and the levels of galectin-3, which plays an important role in inflammation as a proinflammatory mediator, change during the attacks in patients with migraine. The present study aims to compare galectin-3, fibrinogen and D-dimer levels in patients with migraine during the attacks and interictal periods, and to compare galectin-3, fibrinogen and D-dimer levels between patients with migraine and healthy controls to investigate the role of these parameters in the pathogenesis of migraine. Fifty-nine patients with migraine and 30 age-gender matched healthy control subjects were enrolled in the study. Blood galectin-3, fibrinogen and D-dimer levels were measured in patients with migraine. Patients with migraine had higher levels of galectin-3, fibrinogen and D-dimer compared to the healthy controls (p < 0.05). No statistically significant difference was found between galectin-3 and fibrinogen levels during the attacks and interictal period in the migraine group (p > 0.05). Migraine patients had higher D-dimer levels during the attacks compared to the patients in the interictal period in the migraine group (p = 0.05). In conclusion, we found increased levels of fibrinogen, D-dimer and galectin-3 in patients with migraine compared to the healthy control group. Furthermore, we showed increased galectin-3 levels in patients with migraine, and higher D-dimer levels during migraine attacks compared to the interictal periods for the first time. These findings may be associated with the hypercoagulability and neurogenic inflammation during migraine headaches.

Low fetuin-A level in migraine: a case-control study.

Migraine is a type of primary headache which is caused by the alterations in trigeminovascular system. Migraine attacks are associated with neurovascular inflammation of the cerebral and extracerebral vessels, but its pathophysiological mechanisms have not still been fully delineated. Also, migraine has been found to be associated with higher risks for various metabolic disorders. Thus, we aimed to investigate the matrix metalloproteinases (MMP), fetuin-A, ghrelin, and omentin levels which have important roles in metabolic disorders and inflammation, and to examine their relationship with migraine subtypes and attack frequency. Forty-nine migraine patients and 30 age- and sex-matched healthy control subjects were enrolled. Migraine diagnosis was confirmed according to the International Classification of Headache Disorders-II diagnostic criteria. Analyses of MMP9,MMP3, ghrelin, omentin, and fetuin-A were performed by the ELISA method. Fetuin-A, MMP-9, and MMP-3 levels were significantly lower in migraine than controls (p < 0.05). There were no significant differences between groups with respect to omentin and ghrelin (p > 0.05). In migraine patients, serum fetuin-A levels were positively correlated with MMP-9 and negatively correlated with MMP-3. MMP-3, MMP-9, fetuin-A, omentin and ghrelin levels did not correlate with age, disease duration, or frequency of migraine headache (p > 0.05). Migraine patients have lower fetuin-A, MMP-3 and MMP-9 levels than healthy individuals. Migraine patients have low fetuin-A levels, which may be related to the pathogenesis of migraine. The importance and impact of our findings on the pathogenesis, characteristics, and treatment of migraine needs to be investigated in further detailed studies.

Echocardiographic epicardial fat thickness and neutrophil to lymphocyte ratio are novel inflammatory predictors of cerebral ischemic stroke.

BACKGROUND: The role of epicardial fat thickness (EFT) in ischemic stroke (IS) has not been previously investigated. The aim of the present study was to evaluate EFT and neutrophil/lymphocyte ratio (NLR) among patients with IS and to examine the relationship between these inflammatory markers and the incidence of IS. METHODS: The cross-sectional design includes 38 patients with IS and 47 age- and sex-matched healthy controls. Echocardiographic measurement of EFT was conducted according to previously published methods. An automated hematology analyzer was used to generate total and differential leukocyte counts from patient blood samples. RESULTS: Mean EFT was 4.86 ± .68 mm in the control group and 5.95 ± 1.14 mm in the IS group. EFT was significantly greater in the IS patients in relation to the control group (P < .001). Mean NLR was significantly greater among IS patients in relation to the control group (2.5 ± .6 vs. 1.8 ± .4, P < .001). No significant confounding factors were identified in the data set. Spearman's correlation analysis revealed a mild, but highly significant correlation between EFT and NLR (r = .293, P = .006). CONCLUSIONS: This study demonstrates for the first time the association between EFT and cerebral IS. Echocardiographic EFT was significantly correlated with NLR. NLR and echocardiographic EFT represent inexpensive and readily available clinical markers that maybe useful in estimating risk of IS.

Therapeutic effects of thymoquinone in a model of neuropathic pain.

BACKGROUND: The goal of our study was to determine the therapeutic effects of thymoquinone in a dose-dependent manner in a model of neuropathic pain following an experimentally applied spinal cord injury (SCI). METHODS: Fifty female adult Wistar albino rats weighing between 220 and 260 g were included in the study and were divided into 5 groups as follows: Group S (sham), Group C (control), Group T100 (100 mg/kg thymoquinone), Group T200 (200 mg/kg thymoquinone), and Group T400 (400 mg/kg thymoquinone). To begin the experiment, SCI was applied to all groups (with the exception of the sham group) following a mechanical and heat-cold test. Two weeks later, the mechanical and heat-cold tests were repeated, and a single normal saline dose was given to the sham and control groups, whereas 3 varying doses of thymoquinone were given to the other groups. The mechanical and heat-cold tests were repeated at 30, 60, 120, and 180 minutes after receiving thymoquinone. Finally, the animals were put to death via the removal of intracardiac blood. The levels of nitric oxide, total oxidant status, total antioxidant status, paraoxonase, malondialdehyde, tumor necrosis factor-α, and interleukin-1ß were determined in all of the blood samples. RESULTS: The withdrawal threshold and withdrawal latency values recorded from the mechanical and heat-cold allodynia measurements for all 3 thymoquinone groups were higher than that of the control group at all time points (ie, 30, 60, 120, and 180 minutes). There were no differences in these results between the 3 thymoquinone groups. The paraoxonase and total antioxidant status serum levels of all 3 thymoquinone groups were higher than those of the control group, whereas total oxidant status, nitric oxide, malondialdehyde, interleuken-1ß, and tumor necrosis factor-α levels were lower in the 3 thymoquinone groups than in the control group. CONCLUSIONS: Thymoquinone is beneficial for decreasing experimental neuropathic pain following SCI. However, increasing the dose does not change the effect.

Relationship of cognitive performance with prolidase and oxidative stress in Alzheimer disease.

Glutamate excitotoxicity and oxidative stress are held responsible for the pathogenesis of Alzheimer's disease (AD). Prolidase is known to have a crucial part in the recycling of proline for collagen synthesis. Elevated proline levels have been shown to increase glutamate concentration. To our knowledge, prolidase activity in AD has not yet been studied. In this study, we aimed to reveal the relationship of AD with oxidative stress and collagen turnover by comparing AD patients and healthy control group with regard to total antioxidant status (TAS), total oxidant status (TOS), and prolidase levels. Fifty patients (mean age, 72.5 ± 8.9 years) diagnosed with AD and a control group comprised of 39 healthy individuals (mean age, 69.1 ± 7.1 years) were compared relative to serum TAS, TOS, and prolidase levels. The relationship of cognitive performance with prolidase, TAS, and TOS was evaluated by Mini mental state examination (MMSE). Alzheimer's disease group demonstrated statistically significantly higher prolidase and TOS levels as compared to the control group (p = 0.01, p = 0.018, respectively). Total antioxidant status level was significantly lower in the dementia group than in the control group (p = 0.032). MMSE manifested a negative correlation with prolidase and TOS levels (p = 0.001, r = -0.33; p = 0.002, r = -0.32, respectively), while displaying a positive correlation with TAS levels (p = 0.002, r = 0.32). In conclusion, elevated prolidase and TOS levels along with reduced TAS concentrations suggest that oxidative stress and collagen breakdown are involved in the cognitive impairment in AD.

Total oxidant/antioxidant status, copper and zinc levels in acute ischemic stroke patients after mechanical thrombectomy.

BACKGROUND AND PURPOSE: We aimed to identify the relationship of total antioxidant status, total oxidant status, and copper (Cu) and zinc (Zn) situations with the short-term prognostic and stroke severity in acute ischemic stroke cases who were successfully recanalized by mechanical thrombectomy. METHODS: A study of 36 acute ischemic stroke patients and 22 controls were prospectively studied. Tube samples were attained at admission and 24 h after recanalization. In patients who were successfully recanalized (thrombolysis in cerebral infarction ≥ 2b), a 3-month modified Rankin scale (mRS) score of 0-2 was considered a good prognosis, and a score of 3-6 was considered a poor prognosis. RESULTS: Admission Cu levels were significantly higher in the poor prognosis group (p = 0.031). In the multivariate logistic regression analysis, Cu was not associated with poor prognosis (p = 0.357). Cu and Zn levels were lower in the patients group compared to controls (p = 0.014 and p = 0.010, respectively). There was no correlation between National Institute of Health Stroke Scale and biomarkers (p > 0.05). The temporal variation of biomarkers did not differ significantly between the good prognosis and poor prognosis groups (p interaction > 0.05). CONCLUSIONS: High admission Cu levels were associated with poor prognosis, but this association was limited. In addition, Cu and Zn levels were statistically lower in patients. There was no relationship between total antioxidant/oxidant status and short-term prognosis or stroke severity.

A Case of Nasopharyngeal Myiasis Caused by Sarcophaga sp

Myiasis is a parasitic infestation of tissues and body cavities of vertebrates by Diptera larvae. Nasal myiasis is mostly caused by the Sarcophagidae and Calliphoridae families. Many predisposing factors play a role in the appearance of nasal myiasis. In the treatment of the disease, the use of antiseptics together with mechanical cleaning is recommended. In this report, a case of nasopharyngeal myiasis in a 75-year-old patient hospitalized in the intensive care unit is presented. Nine larvae were detected in the patient's nose. Larvae were removed from the area and were cleaned with iodine solution for three days. As a result of macroscopic and microscopic examination, the larvae were identified as the third stage of Sarcophaga sp. in order to prevent myiasis infestations, personnel working in places where the patient is unconscious, such as intensive care units, should daily check the patient's body cavities such as nose, mouth and ear cavities, and perform their care and cleaning.

Oxidative damage is ameliorated by curcumin treatment in brain and sciatic nerve of diabetic rats.

To date, there have not been enough studies about the effects of curcumin against oxidative stress on sciatic nerves caused by streptozotocin (STZ) in diabetic rats. Therefore, this study was undertaken to determine whether curcumin, by virtue of its antioxidant properties, could affect the oxidant/antioxidant balance in the sciatic nerve and brain tissues of streptozotocin (STZ)-induced diabetic rats. A total of 28 rats were randomly divided into four groups of seven rats each: normal controls, only curcumin treated, diabetic controls, and diabetics treated with curcumin. Biomarkers-malondialdehyde (MDA), total oxidant status (TOS), total antioxidant status (TAS), oxidative stress index (OSI), and NO levels-for oxidative stress in the brain and sciatic nerve tissues of the rats were measured. We found a significant increase in MDA, NO, TOS, and OSI, along with a reduction in TAS levels in the brains and sciatic nerves of the STZ-induced diabetic rats (for both parameters p < 0.05). The MDA, TOS, OSI, and NO levels in these tissues were significantly reduced in the curcumin-treated diabetic group compared to the untreated diabetic group. In conclusion, the results of this study suggested that curcumin exhibits neuroprotective effects against oxidative damage in the brain and sciatic tissues of diabetic rats.

A novel predictor in endovascular treatment patients for cerebral perfusion and prognosis: CHA2DS2-VASC.

OBJECTIVE: Thrombolysis in Cerebral Infarction(TICI) score is used to objectively evaluate cerebral perfusion after intervention in acute stroke with mechanical thrombectomy. In our study, we aimed to compare the results of patients with successful TICI perfusion score (TICI ≥ 2c) with the results of patients with poor TICI perfusion score (TICI < 2c) and to investigate the relationship of the CHA2DS2-VASc scoring system with the final TICI perfusion score and other endpoints. METHODS: For this retrospective, single-center, cross-sectional study, 278 patients who underwent endovascular thrombectomy were screened consecutively by the interventional neurology department of hospital. The primary endpoint of the study was in-hospital and 1-year all-cause death. All patients underwent cranial imaging to evaluate hemorrhagic transformation after the procedure. RESULTS: It was observed that CHA2DS2-VASc score was significantly higher in the poor cerebral perfusion group than in the succesful cerebral perfusion group (3.19 ± 1.8 vs 2.72 ± 1.73, p = 0.046). According to Kaplan Meier's analysis, a significant difference was observed in the group with a CHA2DS2-VASc score > 2.5 in terms of all-cause mortality at follow-up compared to the group with a low CHA2DS2-VASc score (p = 0.002). According to Kaplan Meier's analysis, a significant difference was observed in the group with a poor TICI score compared to the group with a succesful one in terms of all-cause mortality at follow-up (p < 0.001). Cox regression model showed that poor TICI score group, Age ≥ 75 years, lower glomerular filtariton rate (GFR), higher high-sensitiveC-reactiveprotein (Hs-CRP), and higher admission NIHSS score were independent predictors of 1-year all-cause mortality. CONCLUSION: High CHA2DS2-VASc score has been shown to be a predictor of unsuccessful cerebral perfusion score and 1-year mortality after mechanical thrombectomy in stroke patients. As a result of our research, it has been shown that complete or nearly complete reperfusion has more positive results than partial reperfusion.

Prevalence of and risk factors for cognitive impairment in patients with relapsing-remitting multiple sclerosis: Multi-center, controlled trial.

BACKGROUND: Cognitive impairment (CI) is a common problem in multiple sclerosis (MS), may occur either in early or late phase of the disease, and impairs quality of life. OBJECTIVES: This study aimed to determine the prevalence of CI and related risk factors in relapsing-remitting MS (RRMS) patients in Turkey. METHODS: The present cross-sectional, multi-center, and nationally representative study included RRMS patients. Sociodemographic characteristics, cognitive functions and additional outcomes were compared between patients with and without CI. RESULTS: The analyses included 487 RRMS patients. According to the BRB-N battery results, CI prevalence was 53.7%. There was a negative significant correlation of BRB-N subtests with age, disease duration, and EDSS and MSNQ-patient rated scores. On the logistic regression analysis, increased age, living in village/rural area, high income level, and high EDSS score were significant increasing risk factors in the development of CI. CONCLUSIONS: This is the first national cognitive data obtained from MS in Turkey, which is a country between Europe and Asia and thus has characteristics of both continents. The similarity of the results of the present study obtained from Turkey to the Western-based data indicates that CI is universal in MS and the main factors affecting CI have not changed.

Effects of Ecballium elaterium on brain in a rat model of sepsis-associated encephalopathy.

Despite recent advances in antibiotic therapy, sepsis remains a major clinical challenge in intensive care units. Here we examined the anti-inflammatory and antioxidant effects of Ecballium elaterium (EE) on brain, and explored its therapeutic potential in an animal model of sepsis-associated encephalopathy (SAE) [induced by cecal ligation and puncture (CLP)]. Thirty rats were divided into three groups of 10 each: control, sepsis, and treatment. Rats were subjected to CLP except for the control group, which underwent laparatomy only. The treatment group received 2.5 mg/kg EE while the sepsis group was administered by saline. Twenty-four hours after laparotomy, animals were sacrificied and the brains were removed. Brain homogenates were prepared to assess interleukin 1beta (IL-1ß), interleukin 6 (IL-6), tumor necrosis factor alpha (TNF-α), total antioxidant capacity (TAC), and total oxidant status (TOS). Brain tissue sections were stained by hematoxylin and eosin (H&E) to semi-quantitatively examine the histopathologic changes such as neuron degeneration, pericellular/perivascular edema and inflammatory cell infiltration in the cerebral cortex. We found a statistically significant reduction in brain tissue homogenate levels of TNF-α 59.5 ± 8.4/50.2 ± 6.2 (p = 0.007) and TOS 99.3 ± 16.9/82.3 ± 7.8 (p = 0.01) in rats treated with EE; although interleukin 6 levels were increased in the treatment group compared to the sepsis group, this was not statistically significant. Neuronal damage (p = 0.00), pericellular/perivascular edema and inflammatory cell infiltration (p = 0.001) were also significantly lower in the treatment group compared to those in the sepsis group. These data suggest that Ecballium elaterium contains some components that exert protective effects against SAE in part by attenuating accumulation of proinflammatory cytokines, which may be important contributors to its anti-inflammatory effects during sepsis.

Identifying autonomic nervous system dysfunction in acute cerebrovascular attack by assessments of heart rate variability and catecholamine levels.

OBJECTIVE: This study aimed to evaluate changes in the autonomic nervous system caused by cerebral lesions due to acute stroke. We assessed heart rate variability and catecholamine levels in lieu of stroke lesion localization. MATERIALS AND METHODS: A total of 60 stroke patients and 31 healthy controls were enrolled in the study. Plasma epinephrine and norepinephrine levels were measured on the first, third, and seventh days following the stroke event. Heart rate variability was evaluated with time-domain and frequency-domain analyses via 24-hour Holter monitor recordings. RESULTS: On the first and third day following the stroke, norepinephrine levels were significantly higher in all patient groups as compared to controls. Epinephrine levels on the first, third and seventh days after the stroke were significantly higher in patients with lesions in the right middle cerebral artery territory than controls. In frequency-domain analysis, patients with right middle cerebral artery territory lesions had greater low frequency and low frequency to high frequency ratio values than controls. Time-domain analysis revealed significant decreases in the standard deviation from the mean for 5-minute 288 R-R intervals in patients with lesions in the right middle cerebral artery and posterior cerebral artery territory when contrasted with controls. Patients with lesions in the right middle cerebral artery territory demonstrated the highest increase in the percentage of consecutive R-R intervals differing by more than 50 ms (pNN50) as compared to the control group. CONCLUSION: These findings indicate that autonomic dysfunction favoring an increase in sympathetic activity occurs in acute stroke patients.

The effects of needle deformation during lumbar puncture.

OBJECTIVE: The aim of this study is to assess deformation of the tip and deflection from the axis of 22-gauge Quincke needles when they are used for diagnostic lumbar puncture (LP). Thus, it can be determined whether constructional alterations of needles are important for predicting clinical problems after diagnostic LP. MATERIALS AND METHODS: The 22-gauge Quincke needles used for diagnostic LP were evaluated. A specially designed protractor was used for measurement and evaluation. Waist circumference was measured in each patient. Patients were questioned about headaches occurring after LP. RESULTS: A total of 115 Quincke-type spinal needles used in 113 patients were evaluated. No deflection was detected in 38 (33.1%) of the needles. Deflection between 0.1° and 5° occurred in 43 (37.3%) of the needles and deflection ≥ 5.1° occurred in 34 patients (29.6%). Forty-seven (41.5%) patients experienced post lumbar puncture headache (PLPH) and 13 (11.5%) patients experienced intracranial hypotension (IH). No statistically significant correlation between the degree of deflection and headache was found (P > 0.05). Epidural blood patch was performed for three patients. Deformity in the form of bending like a hook occurred in seven needles and IH occurred in six patients using these needles. Two of the needles used in three patients requiring blood patch were found to be bent. CONCLUSION: Deformation of needles may increase complications after LP. Needle deformation may lead to IH. In case of deterioration in the structure of the needle, termination of the puncture procedure and the use of a new needle could reduce undesirable clinical consequences, especially IH.

Facial diplegia: etiology, clinical manifestations, and diagnostic evaluation.

OBJECTIVE: Facial diplegia (FD) is a rare neurological manifestation with diverse causes. This article aims to systematically evaluate the etiology, diagnostic evaluation and treatment of FD. METHOD: The study was performed retrospectively and included 17 patients with a diagnosis of FD. RESULTS: Patients were diagnosed with Guillain-Barré syndrome (GBS) (11), Bickerstaff's brainstem encephalitis (1), neurosarcoidosis (1), non-Hodgkin's Lymphoma (1), tuberculous meningitis (1) herpes simplex reactivation (1) and idiopathic (1). In addition, two patients had developed FD during pregnancy. CONCLUSION: Facial diplegia is an ominous symptom with widely varying causes that requires careful investigation.

The relationship between atrial electromechanical delay and left atrial mechanical function in stroke patients.

OBJECTIVE: The aim of this study was to evaluate the relationship between atrial electromechanical delay (EMD) measured with tissue Doppler imaging (TDI) and left atrial (LA) mechanical functions in patients with ischemic stroke and compare them with healthy controls. METHODS: Thirty patients with ischemic stroke were enrolled into this cross-sectional, observational study. The control group consisted of 35 age- and gender-matched apparently healthy individuals patients. Acute cerebral infarcts of probable embolic origin were diagnosed via imaging and were confirmed by a neurologist. Echocardiographically, time intervals from the beginning of P wave to beginning of A wave from the lateral and septal mitral and right ventricular tricuspid annuli in TDI were recorded. The differences between these intervals gave the mechanical delays (inter- and intra-atrial). Left atrial (LA) volumes were measured using the biplane area-length method, and LA mechanical function parameters were calculated. Statistical analysis was performed using student's t-test, chi-squared test, and Pearson's test. RESULTS: The laboratory and clinical characteristics were similar in the two groups. Increased left atrial EMD (21.36±10.38 ms versus 11.74±6.06 ms, p<0.001), right atrial EMD (13.66±8.62 ms versus 9.66±6.81 ms, p=0.040), and interatrial EMD (35.03±9.95 ms versus 21.40±8.47 ms, p<0.001) were observed in stroke patients as compared to controls. Active LA emptying volume and fraction and passive LA emptying volumes and fraction were similar between controls and stroke patients. Total LA emptying volumes were significantly increased in stroke patients as compared to healthy controls (33.19±11.99 mL/m2 versus 27.48±7.08 mL/m2, p=0.021). CONCLUSION: According to the results of our study, interatrial electromechanical delay may be a new predictor for ischemic stroke.
