Brain functions may be affected in PCOS, and studies reported that PCOS patients are at greater risk for developing mental health conditions, including anxiety or depression. Objectives: This study was designed to evaluate the neurocognitive changes in letrozole-induced PCOS model. Methods: Twenty female Wistar rats (eight-week-old; 160 ± 10 g) were divided into two groups. Group one received vehicle only (carboxymethyl cellulose, orally) once daily, and group two received letrozole (1 mg/kg, orally) once daily. Drugs or vehicles were administered for 21 days. Afterward, behavioral tests, including forced swimming test, open field test, and Y-maze alteration task, were performed. Ovaries were removed after behavioral tests and assessed histologically to confirm the induction of PCOS. Results: Animals with PCOS developed depressive-like behaviors compared with control in forced swimming test (P < 0.001). Anxiety-like behaviors were detected in letrozole-induced PCOS group (P < 0.05). Moreover, animals with PCOS exhibited memory impairment in comparison to normal animals in Y-maze memory assessment (P < 0.05). Conclusions: Rats with PCOS showed a neurocognitive decline in the model of letrozole administration. Future studies should be conducted to clarify the exact mechanisms of these changes and possible approaches to restore them.","PeriodicalId":43970,"journal":{"name":"Archives of Neuroscience","volume":" ","pages":""},"PeriodicalIF":0.6,"publicationDate":"2021-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41927866","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Forghani","doi":"10.5812/ANS.111362","DOIUrl":"https://doi.org/10.5812/ANS.111362","url":null,"abstract":"Context: Given its cerebral amyloid angiopathy, subarachnoid hemorrhage might represent transient focal neurological episodes erroneously diagnosed as transient ischemic attacks. The earliest neuroimaging findings in emergency room brain computed tomography indicating subarachnoid hemorrhage in these patients might be very subtle and missed by the clinician. Case Presentation: An 80-year-old man referred with transient focal neurological episodes, suggestive of transient ischemic attacks. In general, except for some cognitive dysfunctions, no remarkable point was noticed in his neurological examination. Non-enhanced brain-computer tomography and magnetic resonance imaging revealed evidence indicating slight convexity subarachnoid hemorrhage at the left frontal cortical region. Conclusions: The transient focal neurological episodes uncommonly represent intracranial hemorrhage. Nevertheless, this clinical representation might occur in patients with subarachnoid hemorrhage due to cerebral amyloid angiopathy. In such cases, the neuroimaging findings play a major role in the differential diagnosis. The misdiagnosis of transient ischemic attacks in these cases might lead to the consumption of antiplatelet drugs and end in catastrophic hemorrhage and life-threatening complications. Close attention to patients' clinical findings and judicious use of further neuroimaging studies would help clinicians to avoid making such mistakes.","PeriodicalId":43970,"journal":{"name":"Archives of Neuroscience","volume":" ","pages":""},"PeriodicalIF":0.6,"publicationDate":"2021-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46476845","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is the second most common serious neurologic disorder after stroke, affecting humans. Since antiepileptic drugs have a narrow therapeutic index and their adverse effects can affect any organ, their widespread use has significant safety implications. Objectives: The study assessed adverse drug reactions (ADRs) using antiepileptic drugs in the Department of Neurology at a Tertiary Care Hospital, Srinagar, Jammu & Kashmir, India. Methods: This prospective observational study was conducted in the Department of Neurology of a Tertiary Care Hospital, Srinagar, Jammu & Kashmir, India, for eight months. It was a spontaneous reporting of ADRs by practicing physicians in the outpatient and inpatient settings that were included in the study. Results: Of the 3,300 patients who were on the anti-epileptic drug (AED), 92 (3.07%) had AED-related ADRs. A total of 18 cases were reported in the inpatient department and 74 cases in the outpatient setting. The most common ADRs were loss of appetite (34.78%), skin rashes (17.39%), and gum hypertrophy (9.78%). Of 80 ADRs, 42.5% were related to valproate, followed by phenytoin, carbamazepine, and levetiracetam. The suspected drug was changed in 22 patients with ADRs. Conclusions: For the early diagnosis and avoidance of ADRs, the frequent follow-up of patients on AEDs is needed to improve patient compliance with drug therapy and provide better drug therapy for avoiding associated morbidity and mortality.","PeriodicalId":43970,"journal":{"name":"Archives of Neuroscience","volume":" ","pages":""},"PeriodicalIF":0.6,"publicationDate":"2021-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49186535","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, most of these techniques have focused on pain assessment and disability. In other words, the intermuscular synchronization between the co-contracting muscles was not considered, and hence, the effectiveness of these techniques on the corticospinal tract function was not studied. Objectives: This study aimed to compare the effects of SMT and MET on corticospinal tract function during four phases of standing, flexion, relaxation, and extension in flexion-extension task (F-ET) in NS-CLBP using pair-wise coherence of Beta-band intermuscular coherence (Bb-IMC). Methods: Twenty volunteer healthy male subjects and twenty-four male subjects with NS-CLBP (20 - 45 years of age) participated in this work. The patients had continuous or recurrent symptoms for three months or more without any referral pain to the lower extremities. The patients were randomly assigned to two equal intervention groups (SMT and MET), and the techniques were applied as described by Greenman. Surface electromyography (sEMGs) from lumbopelvic muscles was recorded for all participants (i.e., healthy group and the patient groups), while they performed three trials of F-ET, and the pair-wise coherence for all muscles was calculated using Bb-IMC analysis. Besides, in the patient's groups, sEMGs from the muscles were recorded before and after the interventional techniques (i.e., SMT and MET), while they performed three trials of F-ET, and the pair-wise coherence was calculated. Multivariate analysis of variance test was used to compare the healthy subjects and patient groups before the interventions in A and B muscle cross at different phases of F-ET task. Furthermore, in the NS-CLBP patients, comparisons were made before and after the interventions in each group (i.e., SMT and MET groups) as well as between the two groups in A and B muscle cross at different phases of the F-ET task. Results: In the standing phase of F-ET, there were no significant differences in the SMT and MET group before and after the intervention in PWC of A muscle cross and B muscle cross (P &lt; 0.05). Considering the flexion phase, there were significant differences in the SMT group in all pair muscles as PWC (M1-M4), PWE (M1-M6), PWC (M4-M6) (P &lt; 0.05), whereas there was one significantly in PWC (M4-M6) in the MET group (P &lt; 0.05). In the relaxation phase, the SMT had significantly in PWC (M2-M5), whereas there was one significantly in PWC (M4-M6) in MET group (P &lt; 0.05). In the extension phase, although the SMT was not significant (P &lt; 0.05) in the MET intervention group, there were significant differences in the PWC (M2-M3) and PWC muscles (M2-M5).

Objectives: Here, we decided to investigate the accuracy of interpreting brain MRI of suspected acute ischemic stroke (AIS) patients conducted by emergency medicine physicians (EMPs) in comparison with a radiologist and a neurologist. Methods: This diagnostic accuracy study was conducted from April to November 2019 in Tehran, Iran. All attending EMPs of one major educational, medical center, a radiologist, and a neurologist also participated. A set of brain MRI stereotypes related to patients suspected of having a AIS was randomly selected. By reviewing the brain MRI interpretation of EMPs, once in comparison with the radiologist and once in comparison with the neurologist, misinterpretations (presence or absence of findings compatible with the diagnosis of AIS) were extracted. Results: Brain MRI stereotypes of 287 suspected AIS patients were interpreted of these patients, 160 cases (55.7%) were male. The mean age of the study patients was 65.0 ± 14.1 (range of 18 to 98) years. The value of the agreement for diagnosis between EMPs and neurologists was 0.684 (95% CI: 0.580 to 0.787). Considering the neurologist as the gold standard, the accuracy of AIS diagnosis by the EMPs was 0.85% (95% CI: 79.3 to 89.6). The agreement value for diagnosis between EMPs and radiologist was 0.673 (95% CI: 0.553 to 0.794). Considering the radiologist as the gold standard, the accuracy of AIS diagnosis by the EMPs was 86.3% (95% CI: 79.8 to 91.3). The agreement value for diagnosis in these two groups was 0.752 (95% CI: 0.627 to 0.877).

Nutritional factors can reduce and prevent the severity and frequency of migraine. Objectives: This study aimed to assess the relationship between major dietary patterns and disease severity among migraine patients. Methods: This cross-sectional study included 266 females (18 - 50 years old) who attend neurology clinics of Sina and Khatam Alanbia hospitals, and a professional headache clinic, both in Tehran, Iran, for episodic migraine diagnosis in 2016. The participants’ data was gathered using a general questionnaire and medical history. Dietary intake was assessed using a 147-item semi-quantitative food frequency questionnaire (FFQ). Anthropometric measurements were taken for all cases. visual analog scale (VAS) and migraine disability assessment (MIDAS) questionnaires were used by a neurologist for assessing migraine disability and pain severity, respectively. Also, principal component analysis (PCA) was used to identify major dietary patterns. The association between dietary patterns and disease severity was evaluated using multinomial logistic regression. Results: Using the PCA, two major dietary patterns, including the healthy and unhealthy diet, were identified. More adherence to the healthy dietary pattern (high in fruits, fruit juices, and dried fruits, vegetables, whole grains, liquid oil, brains, beans, low-fat dairy, and white meat) was associated with a lower VAS score after adjusting for energy intake, BMI, water intake, and increased salt intake (OR = 1.82, 95% CI = 0.96 - 3.44, P-trend < 0.005). The intensity of migraine headache increased by 82% in the lowest adherence to this pattern compared to the most adherence. There was no significant association between healthy and unhealthy dietary patterns with MIDAS before and after controlling for confounding variables. Conclusions: This study showed that adherence to a healthy dietary pattern reduces the severity of pain in migraine patients.

This procedure can be performed under either local or general anesthesia. It depends on the surgical indication, patient’s demand, surgeon’s plan, and need for auxiliary operations. It has been proved that both local and general anesthesia have different complications. Hypnosis is a skill by which hypnotherapists can make changes in perceptual experience and can be used instead of anesthetic drugs on some occasions. The present study was conducted to survey the effectiveness of hypnosis used as an alternative to anesthesia procedures. Case Presentation: A 54-year-old woman was scheduled for bilateral upper lid cosmetic blepharoplasty. Hypnotic anesthesia was conducted owing to her fear of anesthesia and drug-related side effects. Hypnotic anesthesia was accomplished by a hypnotherapist who was an anesthesiologist, and the operation was done without any surgical complications.
