RESUMEN

BACKGROUND: Trunk performance-based therapies are important in the Multiple Sclerosis (MS) rehabilitation process since they have been associated with balance, trunk performance, fall prevention, and walking capacity. Kinesio taping (KT) is a popular approach that has recently been used to treat a variety of musculoskeletal and neuromuscular impairments. Therefore, the aim of this single-blind, randomized controlled study was to investigate the effects of KT combined trunk stabilization-based balance training on balance, trunk control, walking capacity, and fear of falling in patients with MS. MATERIAL AND METHODS: Thirty patients diagnosed with MS were randomly assigned to the KT group or the control group. The control group received core stability-based balance training and the KT group was treated with KT applied on global trunk muscles in addition to core stability-based balance training. Balance was measured with the Mini BESTest, trunk control with the Trunk Impairment Scale, fear of falling with the Falls Efficacy Scale and walking capacity with the 2-minute walk test. RESULTS: Balance, trunk control, fear of falling, and walking capacity of all the patients improved after treatment (p < 0.05). No superiority was found between the groups in terms of treatment efficacy (p > 0.05). CONCLUSION: In conclusion, core stability-based balance training was effective in patients with MS, and the addition of KT had no additional effect in terms of balance, trunk control, fear of falling, and walking capacity.

RESUMEN

INTRODUCTION: Meningiomas are the third most common intracranial tumors in adults after glial tumors and metastases. Olfactory groove meningiomas often grow without symptoms due to their slow growth rates and location in the frontal lobe. Optic nerve sheath meningiomas are benign neoplasms of the meninges surrounding the optic nerve. The coexistence of olfactory groove and optic nerve sheath meningiomas without any history of neurofibromatosis or radiotherapy has never been reported in the literature. CASE REPORT: A 36-year-old female patient was reported with anosmia, headache, memory disturbance, and visual impairment and with the diagnosis of olfactory groove meningioma. In the postoperative period, optic nerve sheath meningioma was detected in the imaging performed due to persistence of visual impairment. CONCLUSION: Olfactory groove and optic nerve sheath meningiomas are rare tumors and can be diagnosed late because they progress slowly. Early diagnosis and treatment may affect the prognosis and morbidity of these patients favorably.

RESUMEN

Purpose: The purposes of this study were to investigate upper extremity function and shoulder position sense in patients with multiple sclerosis and its relation with disability level. Materials and methods: In this study, 20 multiple sclerosis and 20 healthy subjects participated. The disability level was determined by the Expanded Disability Status Scale. Mental state was assessed using the Mini-Mental State Examination. Upper extremity function was measured with the 9-Hole Peg Test and shoulder position sense was evaluated with a Dualer IQTM digital inclinometer. The study protocol was also registered at http://clinicaltrials.gov (NCT03846336). Results: Upper extremity function scores were lower and shoulder position sense error scores were greater in patients with multiple sclerosis in comparison to healthy controls (p < .05). While disability level was associated with dominant and non-dominant upper extremity function, no relationship was found between the disability level and shoulder position sense (p < .05). Only the dominant side shoulder position senses at 30° and 60° abduction were found to be associated with upper extremity function (p < .05). Conclusions: These results indicate that shoulder position sense and upper extremity function were affected in patients with multiple sclerosis with mild to moderate disability. Upper extremity functions were associated with shoulder abduction joint sense in patients with multiple sclerosis. In the assessment of upper extremity functions, joint position sense should be taken into account even at early stages of multiple sclerosis, so it may provide guidance in planning rehabilitation programs.

RESUMEN

OBJECTIVES: Idiopathic Parkinson's Disease is a neurodegenerative disease caused by the loss of cells that secrete dopamine in the basal ganglia. Galectins are multipotent, evolutionarily conserved, cell surface glycoconjugated and crosslinked carbohydrate-binding proteins. The roles of these proteins in the diagnosis of the disease have been investigated. PATIENT AND METHODS: Patients who were diagnosed with idiopathic Parkinson's disease were classified as early (stage 1-2) and advanced stage (stage 3-5) according to the Hoehn-Yahr classification. In addition, voluntary cases without parkinson disease constituted the control group. Serum samples of consecutive Parkinson patients and age and gender matched healthy controls were used to measure serum galectin-3 and serum galectin-4 levels. The levels were compared between Parkinson's patients and control groups and early and advanced stage Parkinson's groups. RESULTS: Thirty age and gender-matched healthy controls and 60 parkinson patients were enrolled in the study. Serum galectin-3 levels were lower in controls compared with patients (892.9 (168.2-2416.3) vs. 2271.8 (375.9-9673.4), respectively, P < 0.01). Serum galectin-3 levels were related to Hoehn-Yahr stages and (r: 0.691, P < 0.001). The early stage group (20 patients) had lower serum galectin-4 levels compared with advanced stages (40 patients) (197.97 ± 46.42 vs. 334.263 ± 37, respectively, P < 0.01). Serum galectin-4 levels were also lower in controls compared with patients 185.1 (116.2-313.3) vs. 282.3 (156.9-984.8), respectively, P < 0.01. ROC analysis showed that serum galectin-3 and galectin-4 were statistically significant in the identification of Parkinson disease and advanced stages. The results were significant for galectin-3 (AUC: 0.89, SE: 0.034, P < 0.001 and CI: 0.823-0.958; P < 0.001) and for galectin-4 (AUC: 0.758, SE: 0.05, P < 0.001). CONCLUSION: Serum galectin-3 and galectin-4 may be potential noninvasive markers for the identification of Parkinson disease and advanced stages.

RESUMEN

BACKGROUND: Platelet to lymphocyte ratio (PLR) and neutrophil to lymphocyte ratio (NLR) as recently emerging thrombo-inflammatory indicators were significantly associated with both major cerebrovascular/cardiovascular adverse events (MACE) and mortality. Therefore, we aimed to assess the effects of combinations of PLR and NLR in predicting the presence of CVST and in-hospital MACE. METHODS: A total of 277 participants comprising 80 patients with evidence of CVST and 197 controls with similar baseline characteristics were included in this retrospective study. Patients were classified into 3 groups based on the optimal cut-off values of PLR and NLR calculated with receiver operating characteristic (ROC) curve for in-hospital MACE rates. RESULTS: PLR (148±61 vs 101±50, p<0.001) and NLR (3.12±1.4 vs 1.94±1.1, p<0.001) were significantly higher in the CVST group. Furthermore, patients in the high risk group (a PLR of ≥115.0 and an NLR of ≥2.1) had the highest in-hospital MACE rates including seizure (p=0.012), papilledema (p=0.025) and diplopia or blurry vision (p=0.028). After multivariate logistic regression analysis MPV, PLR (1.052 [1.045-1.059], p=0.001) and NLR (1.442 [1.086-1.916], p=0.012) were found as independent predictors of CVST. CONCLUSION: These results suggest that PLR and NLR are easily available and cheap thrombo-inflammatory indicators, so that PLR and NLR could be used in prediction of CVST and in-hospital MACE.

RESUMEN

We report a case with calciphylaxis very rarely presenting with bilateral optic neuropathy, acral gangrene and visceral ischaemia. Bilateral papilloedaema was found in a 43 year-old female with chronic renal failure. Acral dry gangrene was observed. Pathological examination of her amputated thumb revealed calcification, thrombi, obstructive endovascular fibrotic areas in the walls of arteries. She was diagnosed with calciphylaxis. Bilateral optic neuropathy was defined secondary to calciphylaxis. Abdominal computerized tomography revealed prominent calcifications in mesenteric, spleen and renal arteries. She died eight months after the diagnosis. Calciphylaxis should be considered in the differential diagnosis of the optic neuropathy.

RESUMEN

BACKGROUND: The clinical importance of F-wave inversion in the diagnosis of Carpal Tunnel Syndrome (CTS) is not yet well known. OBJECTIVE: This study aims to investigate the value of F-wave inversion in diagnosing CTS, and to evaluate the relationship of F-wave inversion with age, gender, diabetes mellitus, body mass index (BMI), wrist or waist circumferences. METHODS: Patients (n=744) who were considered to have CTS with clinical findings were included in the study. In order to confirm the diagnosis of CTS, standard electrophysiological parameters were studied with electroneuromyography. In addition, median nerve F-wave measurements were done and we determined if F-wave inversion was present or not. Sensitivity and specificity of F-wave inversion were investigated for its value in showing CTS diagnosed by electrophysiological examination. RESULTS: CTS diagnosis was confirmed by routine electrophysiological parameters in 307 (41.3%) patients. The number of the patients with the presence of F-wave inversion was 243 (32.7%). Sensitivity of F-wave inversion was found as 56% and specificity as 83.8%. BMI and wrist circumference values were significantly higher in patients with F-wave inversion present than those with F-wave inversion absent (p=0.0033, p=0.025 respectively). CONCLUSIONS: F-wave inversion can be considered as a valuable electrophysiological measurement for screening of CTS.

RESUMEN

Carpal tunnel syndrome (CTS) has a multifactorial etiology involving systemic, anatomical, idiopathic, and ergonomic characteristics. In this study, an investigation of the relationship between the CTS degree established by electrophysiological measurements in patients with clinical CTS prediagnosis, and age, gender, body mass index (BMI), hand wrist circumference, and waist circumference measurements has been done. On 547 patients included in the study, motor and sensory conduction examinations of the median and ulnar nerve were done on one or two upper extremities thought to have CTS. In terms of CTS severity, the patients were divided into four groups (normal, mild, medium, and severe CTS). A total of 843 electrophysiological examinations were done consisting of 424 on the right hand wrist and 419 on the left hand wrist. When the age group of 18-35 years is taken as the reference group, the CTS development risk independent of BMI has been found to have increased by a factor of 1.86 for ages 36-64 years, and by 4.17 for ages 65 years and higher after adjustment for BMI. With respect to normal degree CTS group, the BMI were significantly different in groups with mild, medium, and severe CTS. The waist circumferences of groups with mild, medium, and severe CTS severity were found to be significantly higher in comparison to the normal reference group. When this value was corrected with BMI and re-examined the statistically significant differences persisted. The study identified a significant relationship between the CTS severity and age, BMI, waist circumference.

RESUMEN

The aim of this study was to investigate serum paraoxonase and arylesterase activities, and to determine oxidative status via the measurement of total oxidant status (TOS), total antioxidant status (TAS) and the oxidative stress index (OSI) in patients with relapsing-remitting multiple sclerosis (RRMS). Results were compared with data from healthy controls. A total of 60 subjects, including 30 newly diagnosed and untreated patients with RRMS (20 females, 10 males, 18-40 years of age) and 30 healthy controls (20 female, 10 male 20-40 years of age) were enrolled in this study. The oxidative status of the RRMS patients was measured by TOS, TAS and estimation of the OSI was made by a new automated method. Paraoxonase (PON1) and arylesterase activities were measured spectrophotometrically. TAS levels of RRMS patients were significantly lower than that of controls (p < 0.05). TOS levels of RRMS patients were higher than that of controls (p < 0.05). PON1 and arylesterase activities of RRMS patients were lower, but not significantly, than those of controls (p > 0.05). There was no correlation between serum PON1 activity and OSI in patients with RRMS (p > 0.05). Hypercholesterolemia was not observed in multiple sclerosis patients. In conclusion, although the mechanism underlying the significant reduction of TAS levels of multiple sclerosis patients compared with those of controls is unknown, the results imply that endogenous antioxidants may have been exhausted by increased oxidative stress and we believe that additional antioxidant treatment might be beneficial for these patients.

RESUMEN

The aim of this study was to investigate the relationship between vitamin D and bone mineral density in newly diagnosed multiple sclerosis (MS) and to compare results with data from healthy controls. A total of 60 subjects, including 30 patients with MS, newly diagnosed and untreated (18 females, 12 males, at 18-40 years of age) and 30 healthy controls (20 female, 10 male) were enrolled in this study. Bone mineral density (BMD) of the lumbar spine and left femoral neck region were measured by dual-energy X-ray absorptiometry (DEXA). Serum levels of 25-hydroxyvitamin D (25OHD) were measured by chemiluminescence microparticle immunoassay (CMIA) on the Architect-i2000(®) (Abbott) system. 25OHD levels of MS patients were significantly lower than in controls. 25OHD levels were 27.2 ± 14.1 ng/ml in MS patients and 42.6 ± 8.8 ng/ml in controls (p = 0.001). Twenty-six (86.6 %) of our patients had a reduced BMD in lumbar spine or femoral neck region; of these 24 patients (80 %) had osteopenia and 2 patients (6.6 %) had osteoporosis. Interestingly, there was no significant correlation between 25OHD and BMD in lumbar spine and femoral neck region (r = 0.454, p = 0,074; r = 0.636, p = 0.082). Interestingly, a significant reduction of bone density in female MS patients was observed. In our study, 25OHD deficiency and lower BMD appeared in newly diagnosed multiple sclerosis. This is compatible with shared etiologic or pathogenic factors in MS and osteopenia/osteoporosis, and calls for an active approach to optimize bone health in early stages of MS.

RESUMEN

The aim of this study was to investigate retinal nerve fiber layer (RNFL) thickness in patients with Alzheimer disease (AD) without visual impairment using spectral domain optical coherence tomography (SD-OCT) and to compare the results with healthy controls. A total of 80 subjects, including 40 patients with early untreated AD (mean age, 69.3 ± 4.9 years) and 40 healthy controls (mean age, 68.9 ± 5.1 years) were enrolled. Both eyes of patients with AD and controls were imaged using SD-OCT. The average RNFL thickness was significantly less in the AD patients than in controls (65 ± 6.2 µm vs 75 ± 3.8µm; P = 0.001). There was selective thinning of the RNFL in the superior quadrant, the mean superior quadrant RNFL thickness being 76 ± 6.7 µm in AD patients and 105 ± 4.8 µm in controls (P = 0.001). In our study, the thickness of RNFL in patient with AD was lower than that of controls. This suggests that SD- OCT has the potential to be used in the early diagnosis of AD as well as in the study of therapeutic agents. Further studies are needed to validate this technology as a viable ocular biomarker over time in AD.

RESUMEN

OBJECTIVE: To report a case of pituitary adenoma apoplexy presenting with bilateral proptosis and bilateral third nerve palsy that developed after cardiovascular surgery. CLINICAL PRESENTATION AND INTERVENTION: A 45-year-old man developed bilateral proptosis and bilateral third nerve palsy after a coronary artery bypass grafting operation. A pituitary macroadenoma with extension into the sphenoid sinus and cavernous sinus with bilateral involvement was resected on computed tomography scan by microscopic transsphenoidal procedure. Third nerve palsy improved partially on the first postoperative day and completely improved in the fourth month after the operation. CONCLUSION: This is a rare case of pituitary adenoma apoplexy that presented with bilateral third cranial nerve palsy.

RESUMEN

Multiple sclerosis (MS) can cause alterations in autonomic cardiovascular functions. We aimed to investigate the correlation of disease activity and disability with heart rate variability (HRV) of cardiovascular autonomic dysfunction (CAD) demonstrated by 24-h Holter monitorization. Thirty-four patients with clinically active relapsing-remitting MS, age 33.8 +/- 7.6 years, were studied. Twenty healthy volunteers served as controls. The time domain long-term HRV parameters were recorded by a digicorder recorder calculated by ambulatory electrocardiograms. Variabilities in time domain were lower in the MS patients: SDNN (standard deviation of all R-R intervals, p = 0,019), SDANN (standard deviation of the averages of R-R intervals in all 5-minute segments of the entire recordings, p = 0,040), RMSSD (the square root of the mean of the sum of the squares of differences between adjacent R-R intervals, p = 0,026), HRVM (mean of the SDNN in all the 5-minute intervals, p = 0,029), HRVSD (standard deviation of the SDNN in all the 5-minute, p = 0,043). These results suggest that MS causes CAD manifesting as long-term HRV abnormalities. This illness seems to cause a dysfunction in parasympathetic cardiovascular tone. Depressed HRV parameters are independent from the clinicalfindings, but the illness progression partially seems to provoke a decrease in such parameters.

RESUMEN

Multiple Sclerosis (MS) is a chronic inflammatory demyelinating disease of the central nervous system, with highly variable clinical course that most typically exhibits a relapsing-remitting pattern. Neuroimaging, pathological findings and response to available therapies are also not uniform. It commonly affects young adults and is usually characterized in the early years by acute relapses followed by partial or complete remission; in later years progressive and irreversible disability develops. The clinical course of MS is defined as relapsing-remitting (RRMS), primary progressive (PPMS), progressive relapsing (PRMS) and secondary progressive (SPMS). The treatment of RRMS is based on the use of immunosuppressive and immune-modulating therapy. Immunosuppressive agents have been used in multiple sclerosis for decades. Intravenous methylprednisolone is currently the treatment of choice for the relapses. The currently approved treatments for MS are disease-modifying agents, which only reduce the attack rate and delay progression in some patients and are believed to be effective only for the inflammatory component of the disease. Immunomodulating and immunosuppressive treatments are directed against the inflammatory process and are only partially effective. In RRMS, positive effects on disease activity have slowed disability progression, but in PPMS the same degree of effect of immunotherapies on relapses and active MRI lesions had little or no effects on the progression of disability. This partial failure could be explained by mechanisms of axonal damage at least partially independent from acute or chronic inflammation. This suggests that there is a need for better use of available treatments and the necessity of alternative new therapeutic options to stop disease progression and improve recovery mechanisms. The practicing neurologist must understand the MS spectrum and evaluate patient-specific factors to determine the best strategy for therapy.

RESUMEN

Prospective study of the neuroprotective activity of sildenafil in a rat spinal ischemia model. The present study involved 21 male Sprague-Dawley rats. The animals were divided into 3 groups. Physiological serum was administered intraperitoneally to the 8 rats in the control group at the beginning of reperfusion for a period of 20 min after abdominal aortal occlusion. Sildenafil (Viagra) was administered as a single 10-mg/kg/day intraperitoneal dose to the 8 rats in the sildenafil group at the beginning of reperfusion after 20 min of abdominal aortal occlusion. No occlusion was performed and no agent was administered to the 5 rats in the sham group, but the abdominal aorta was reached by means of surgical intervention. Before the animals were sacrificed, several physiological and biochemical parameters were investigated, preoperative and postoperative motor functions were also assessed, and somatosensory evoked potential (SEP) monitoring and histopathological examinations were carried out. No differences were found between the physiological and biochemical parameters in each of the 3 groups. Neurological scoring performed after reperfusion demonstrated a significant improvement in the neurological results relative to those of the control group over 48 h in subjects that received sildenafil. These animals also showed better 24-hour SEP results, measured in terms of extended latency and decreased amplitude, than the control animals. A histopathological study showed reduced ischemic symptoms in rats that received sildenafil compared with those in the control group. However, no anomalies were observed in the sham group with respect to the histopathological and neurological findings. These results indicate that neurological damage due to spinal-cord ischemia-reperfusion injury can be reduced by sildenafil.

RESUMEN

Attention deficit hyperactivity disorder (ADHD) is a neurobehavioral disorder characterized by pervasive inattention and/or hyperactivity-impulsivity. It has been suggested that ADHD symptoms are associated with restless legs syndrome (RLS), which is a neurological condition that is defined by an irresistible urge to move the legs. Increasing evidence suggests iron deficiency may underlie common pathophysiological mechanisms in subjects with ADHD and with RLS. To further define the relationship between iron deficiency and RLS in children and adolescents with ADHD, we evaluated 87 ADHD subjects: 79 boys and 8 girls with age 9.3 +/- 2.5 years (6-16 years). Various psychopathologies and the severity of the ADHD symptoms and serum ferritin levels were assessed. Diagnosis of RLS was made according to the International RLS Group criteria. The patients were evaluated for the iron deficiency (ferritin < 12 ng/ml). RLS was found in 29 (33.3%) of the 87 ADHD subjects. Parent- and teacher-rated behavioral and emotional problems and the severity of ADHD symptoms were not significantly different between ADHD subjects with RLS and those without RLS (n = 58). The rate of iron deficiency was significantly higher in ADHD subjects with RLS (n = 6, 20.7%) when compared with ADHD subjects without RLS (n = 1, 1.7%, p = 0.005). Our results showed that depleted iron stores might increase the risk of having RLS in ADHD subjects. Iron deficiency, which is associated with both ADHD and RLS, seems to be an important modifying factor in the relationship between these two conditions.

Behçet's disease (BD) is a chronic, recurrent multisystem inflammatory disorder firstly described by Turkish dermatologist Dr. Hulusi Behçet in 1937. The classic triad consists of recurrent oral and genital ulcerations and uveitis. The article presents the value of visual evoked potential findings of a series of 44 patients with BD without neurological manifestations seen at the Medical Hospital in Neurology and Dermatology clinics over the past 8 years. The mean latency value of positive peak P100 in BD patients was significantly delayed compared to that of control subjects (patients's mean: 105.6 ms in right eye and 107.7 ms in left eye; control subject's mean: 101.4 ms in right eye and 101.7 ms in left eye).

RESUMEN

The morphological features of centrotemporal spike discharges (CTSD) and relationship of them with clinical diagnosis in cases with benign epilepsy of childhood with centrotemporal spikes (BECTS) and the other epileptic syndromes of childhood as well as some nonconvulsive neurological disorders were detected in the routine patient population who referred to the authors' EEG laboratory. Thirty-six cases (21 males, 15 females; 8 months-14 years old), in which awake and/or sleep EEGs revealed CTSD were included in this study. The cases were divided into two groups as epileptic and nonepileptic. The cases with seizure were divided into BECTS and the other epilepsies. Of the epileptic cases, 14 (38.8%) patients had typical rolandic seizures. In five cases, there were partial or secondary generalized seizures. Two cases had myoclonic seizures. In the nonepileptic group, there was mental retardation/behavioral disturbances in five cases; there were periodic syndromes of childhood such as migraine and equivalents of migraine in three cases; febrile convulsion in three cases, breath-holding spells in two cases, and primary enuresis nocturna in two cases. In the nonepileptic group, the discharges were significantly fewer than the other groups (p = .014). More frequent discharges occuring for shorter periods were more significantly observed in BECTS group (64%). Typically isolated spike and slow-waves in T3/T4 and C3/C4 location were significantly more common (86%) in rolandic epilepsy group (p = .01). The EEGs of cases with BECTS had more frequency in the cluster of discharges than the other groups (p = .018). Multifocal discharges were observed in 28.5% of cases with BECTS, in 20% of nonepileptic group, and in 71.4% of other epileptics in the trial. Although these epileptic and nonepileptic conditions have some differences in view of frequency and morphology and location, CTSDs could be manifested in the group without seizure. It was concluded that the similar focal abnormalities which could be seen in rolandic epilepsy may be observed in the other epileptic or nonepileptic disorders of childhood and this condition may be originated from the involvement of similar central structures.

RESUMEN

An 11-year-old boy presented with convulsion, fever, rash, abdominal pain, swelling on the eyelids, elbow and wrists, oliguria and hematuria. Based on the abnormal findings the patient was diagnosed with Henoch-Schönlein purpura. On the 3rd day of admission, neurological examination showed ataxic gait, loss of deep tendon reflexes, and decreased (4/5) of muscle strength on all extremities. Additionally, bilateral loss of touch, pain and temperature sensation in a glove, from the elbows to distal region (on C5-T1 level) was diagnosed. Cerebrospinal fluid examination and cranial magnetic resonance imaging (MRI) were normal. The patient was discharged with oral prednisolone on the 7th day of admission. One week after discharging from the hospital, he was re-admitted with vertigo and seizures. He was in coma. MRI of cranial, cervical and cervical plexus were normal. Electromyography showed severe bilateral brachial plexopathy. Prednisolone and intravenous immunglobulin (IVIG) therapy were given without significant improvement. He was discharged from the hospital on the 17th day of admission. On the second month of follow-up, a second cure of IVIG was given because of no clinical improvement. Now, he is on the 4th month of follow-up, unfortunately, no improvement was noted on his muscle strength and sensorial abnormalities on the upper extremities.
