RESUMO

microRNAs are candidate diagnostic biomarkers for Alzheimer's disease. This study aimed to compare Silymarin with Rosuvastatin and placebo on total-Tau protein level and expression levels of microRNAs and TGF-ß and COX-2 in Alzheimer's patients with secondary dyslipidemia. 36 mild AD patients with dyslipidemia were divided into three groups of 12. The first group received silymarin (140mg), the second group received placebo (140mg), and the third group recieved Rosuvastatin (10mg). Tablets were administered three times a day for Six months. The blood samples of the patients were collected before and after the intervention and the serum was separated. Using the RT-qPCR method, the expression levels of miR-124-3p and miR-125b-5p were assessed, and the serum levels of total-Tau, TGF-ß, and COX-2 enzyme were measured using the ELISA method. Data were analyzed with SPSS software. In this study, the level of Δtotal-Tau was significantly lower in the Rosuvastatin group compared to the placebo (P = 0.038). Also, a significant reduction in the level of ΔTGF-ß was observed in the Silymarin to Rosuvastatin group (p = 0.046) and ΔmiR-124-3p was significantly increased in the Rosuvastatin compared to the placebo group (p = 0.044). Rosuvastatin outperformed silymarin in decreasing Δtotal-Tau serum levels and enhancing expression of ΔmiR-124-3p, attributed to Rosuvastatin's capacity to lower cholesterol levels and inflammation concurrently. Conversely, silymarin was more effective than Rosuvastatin in reducing levels of ΔTGF-ß. Serum miR-124-3p could serve as a promising diagnostic biomarker and a new therapeutic focus in AD.

RESUMO

Nasal Septal Deviation (NSD) is a common sign in otorhinolaryngology that can lead to facial asymmetry. In this case-control observational study, we assessed the role of EMG and NCS in the diagnosis of NSD and its effect on neuromuscular function. Participants were divided into two groups based on paranasal sinus computed tomography scan (PNS CT) results: NSD cases (n = 21) and controls without NSD (n = 13). EMG and NCS were performed on both groups to assess nasal alar muscles at the root of the zygomatic nerve. Our findings showed a significant correlation between NSD and EMG/NCS tests (P-value = 000) and a significant association between septal deviation and nasal alar lateralization (P-value = 000). EMG/NCS can be useful in assessing NSD by providing a better understanding of related neuromuscular structures and neuromuscular function of the nasal alar dilator muscles and aid in the diagnosis of NSD.

RESUMO

Research has demonstrated the potential efficacy of intensive short-term dynamic psychotherapy (ISTDP) in addressing medically unexplained symptoms (MUS). However, the specific application of ISTDP for tension-type headache (TTH), a prevalent and common MUS, has not been extensively studied. In light of this gap in the literature, the current study investigated the effectiveness of intensive short-term dynamic psychotherapy (ISTDP) in treating TTH. The study assessed ISTDP's impact on emotion regulation (ER) capacities, levels of anxiety and anger, and TTH symptoms. 30 patients from the neurology clinic at Hazrat Rasool Hospital in Tehran were randomly assigned to either the intervention (n = 15) or control (n = 15) group. Pre- and post-treatment evaluations were conducted, followed by a ten-week follow-up assessment. Data were analyzed using repeated measures analyses of variance. The results indicated that ISTDP led to significant improvements in ER, reductions in anxiety and anger levels, and a significant decrease in TTH symptoms (ps < 0.001). Findings underscore the effectiveness of ISTDP as a valuable therapeutic approach for addressing TTH.

RESUMO

Background: Amyloid-beta (Aß) production is a normal physiological process, and an imbalance in Aß production/excretion rate is the basis of the plaque load increase in AD. LRP1 is involved in both central clearance of Aß from the CNS and transport of Aß toward peripheral organs. In this study, the effect of silymarin combination compared to rosuvastatin and placebo on neuro-metabolites and serum levels of LRP1 and Aß1-42 proteins and oxidative stress enzymes and lipid and cognitive tests of Iranian AD patients. Methods: In this double-blind placebo-controlled study, thirty-six mild AD patients were divided into groups (n=12) of silymarin 140mg, placebo, and rosuvastatin 10mg. Medications were administered 3 times a day for 6 months. Clinical tests, lipid profile (TG, HDL, TC, and LDL), Aß1-42, and LRP1 markers were measured at the beginning and end of the intervention. Magnetic resonance spectroscopy (MRS) was used to measure metabolites. Using SPSS software a one-way ANOVA test was used to compare the means of the quantitative variables and Pearson and Spearman's correlations to measure the correlation. GraphPad Prism software was used for drawing graphs. P < 0.05 was considered a significant. Results: The levels of LRP1 and Aß1-42 in the silymarin group were significantly increased compared to the other groups (P < 0.05). NAA/mI in the silymarin group had a significant increase compared to both placebo and rosuvastatin groups (P < 0.05). Right and left hippocampal mI/Cr directly correlated with TG (r = 0.603, P = 0.003 and r = 0.595, P = 0.004, respectively). NAA/Cr of the right and left hippocampus was inversely related to TG (r = -0.511, P = 0.0033, and r = -0.532, P = 0.0021, respectively). NAA/Cr and NAA/mI of bilateral hippocampi directly correlated with HDL (P < 0.05). An inverse correlation was observed between the Aß1-42 and mI/Cr of the right and left hippocampus (r = -0.661, P = 0.000 and r = -0.638, P = 0.000, respectively). Conclusion: Donepezil and silymarin improved lipid profile associated with increased NAA/Cr, and decreased mI/Cr, in AD patients. Biomarker NAA/mI can be clinically significant in examining AD pathology. Measurement of the lipid factors and neurometabolites can be a suitable method for monitoring this disease.

RESUMO

Supplementary motor area, the posterior third of the medial aspect of superior frontal gyrus, is known to be a heterogeneous area in function. It is involved in self-initiated motor movements, planning and sequencing the motor action, response inhibition, and bimanual movements. Blood supply for supplementary motor area is mostly by callosomarginal branch of anterior cerebral artery. Stroke in anterior cerebral artery territory is relatively uncommon, moreover, isolated supplementary motor area stroke is a rare entity. Supplementary motor area stroke, as a syndrome, has variable symptoms consisting of impairment of volitional movements, hemineglect, dyspraxia of contralateral limbs, impaired muscle tone, mutism and contralateral weakness. As symptoms are sometimes ambivalent, patients may be misdiagnosed as functional disorder and lose the chance for immediate adequate treatments such as thrombolysis. We report a 59-year-old man with previous history for myocardial infarction, referred to emergency room with an acute dense right-side hemiplegia, positive Hoover sign, asymmetrical Babinski responses and intermittent ability to move his arm in some specific reflex actions despite plegia. Since brain computed tomography scan was unremarkable we could not be sure whether his symptoms were organic or functional until a diffusion weighted imaging of magnetic resonance imaging elucidated the situation. To our knowledge, there is only one case report in the literature prior to ours, presenting a supplementary motor area stroke patient, mimicking functional disorder. Therefore, we may claim our report to be the second reported case.

RESUMO

Neurofibromatosis type 1 (NF-1) is a common hereditary neuro-cutaneous disease, with known gene mutations, that mainly involves the skin and nervous system. Multiple sclerosis (MS) is an acquired inflammatory disease in which the myelin of nerve cells in the brain and spinal cord is damaged. These two disease do not share any apparent pathological similarities. We herein present a 32-year-old woman with definite NF-1, who has recently been diagnosed with MS, which to the best of our knowledge is a rare co-occurrence. Though there are often neurologic sign and symptoms in patients with NF-1, they should not always be considered as the natural history of the disease, and other overlapped pathologies should be kept in mind, in order to not miss or postpone the efficient treatment.

RESUMO

Motor neuron diseases have been reported as a rare paraneoplastic syndrome (PNS) of a systemic neoplasm. We present a patient with amyotrophic lateral sclerosis (ALS) in association with neuroendocrine tumor (NET) of stomach, which is the first case of motor neuronopathy with underlying neuroendocrine tumor. A 79-year old woman presented with a two months history of progressive dysphagia, spastic dysarthria and marked fasciculation in her atrophic tongue. Gag reflexes were diminished bilaterally. Other cranial nerves were intact. In muscle testing there was significant atrophy in thenar and hypothenar areas of both hands compatible with diffuse motor neuronopathy with active denervation. Upper GI endoscopic study showed patchy erythematous mucosa with congestion in body of stomach, Histological biopsy of stomach confirmed the neuroendocrine tumor (NET). The importance of considering a paraneoplastic syndrome in a patient with presentation of ALS, which can leads to searching for underlying neoplasm before its apparent signs and symptoms, to initiate tumor treatment so much sooner. In addition even though paraneoplastic motor neuron disease is rare, treating the underlying neoplasm may resolve neurologic signs and symptoms.

RESUMO

Multiple sclerosis (MS) is the most prevalent central nervous system demyelinating disease. There are known risk factors for MS. However, there is uncertainty in its protective factors. Few studies have demonstrated that some chronic infections may have protective effects on this disease. We carried this study to investigate the relation between Helicobacter pylori (HP) infection and the prevalence and severity of MS. In this case-control study, 163 MS patients and 150 sex- and age- matched controls were included. Blood samples for IgG and IgM anti HP antibodies were collected from all individuals. Also, the Expanded Disability Status Scale (EDSS) was used to evaluate the MS patients. Suitable statistical analysis was applied. A Significant difference was observed in seropositivity between these two groups (P<0.001) but no significant difference was seen in seropositivity between conventional and opticospinal MS (P=0.522). No significant difference was observed in seropositivity among ages (P=0.075) and between genders (P=0.204). A significant difference was seen in EDSS value between seropositive and seronegative patients (P=0.017). We concluded that patients with HP infection had lower incidence of multiple sclerosis and MS patients with HP infection showed lower neurologic complications, which can demonstrate that HP infection may have a protective influence on MS pathogenesis.

RESUMO

BACKGROUND: Recently, homocysteine (Hcy), folate, and vitamin B12 have been proposed to have several roles on MS pathogenesis. OBJECTIVE: We performed this study to determine the role of serum levels of Hcy, vitamin B12, and folate in patients with relapsing remitting MS (RRMS) and compared them with healthy controls. METHODS: We recruited 75 RRMS patients and 75 subjects as controls with the same age and sex. Homocysteine was measured using fluorimetric high-performance liquid chromatography. Plasma folate and vitamin B12 levels were measured through ion-capture method. RESULTS: Mean plasma levels of vitamin B12, folate, and Hcy in cases were 342.64 ± 210.66 pg/ml, 9.74 ± 4.77 ng/ml, and 22.73 ± 11.63 µM/L, respectively, which showed significant difference in comparison with the controls. In addition, there were significant correlations between mean serum Hcy levels and duration of disease (r=0.2, p=0.05) and treatment with interferon (r=0.21, p=0.01). In cases, Hcy level was higher among those on ß interferon (24.56 ± 11.87 vs. 19.71 ± 10.75, p=0.01). CONCLUSIONS: We concluded that serum levels of vitamin B12 and folate decreased in RRMS patients, but Hcy levels increased significantly. It seems necessary to conduct prospective trials to determine whether the treatment with supplements and correct biomarker levels in the early stage of the disease can change the course of the disease. We recommend regular checking of the serum level of Hcy in patients who use disease-modifying drugs.
