Background: Peripheral nerve ultrasound(US) has been used as a promising diagnosing technique for peripheral nerve disorders. This study aimed to compare the US findings of Guillain-Barre syndrome (GBS) with chronic inflammatory demyelinating polyneuropathy (CIDP). Methods: This case-control study was done on 25 patients with GBS at 3 weeks after onset of disease and 25 patients with CIDP. Demographic information and US results of median nerve at 2 points, ulnar nerve at 3 points, and tibial and peroneal nerves were collected. Results: Left median nerve diameter in patients with CIDP with the mean of 0.141 ± 0.047 was more than GBS group with the mean of 0.095 ± 0.034 (P < 0.001). Both sides of median nerve diameter in patients with CIDP were higher than patients with GBS (P < 0.05), but in the left side, it was more in patients with CIDP (P = 0.003). Conclusion: The diameter and circumference of median, ulnar, and tibial nerves in forearm and elbow of patients with CIDP are more than patients with GBS; therefore, it may be possible to use US findings based on these differences in diagnosis and differentiation of the two diseases.

Background: Multiple sclerosis (MS) is an inflammatory chronic disease of the central nervous system (CNS) which is related with unpredictable course and increasing disability. Social support as an available interpersonal resource may help patients with MS. The purposeof the present studywas to evaluate perceived social support in patients with MS as well as the associated factors. Methods: The sample of this cross-sectional study included 200 patients with MS. Data collection was performed by the completion of the Multidimensional Scale of Perceived Social Support (MSPSS) and a questionnaire which included patients' characteristics. Results: Patients reported to perceive high support from significant others and their family (median: 24.0 and 23.5, respectively) and less from their friends (median: 20). Moreover, a statistically significant association was found between social support from significant others and marital status (P = 0.010), modification of daily activities (P = 0.018), difficulties with social and family environment (P ≤ 0.001 and P ≤ 0.001, respectively), frequent urination (P = 0.015), and whether they easily forgot (P = 0.049), characterized themselves as anxious (P = 0.049), and believed in God (P = 0.002). Also, a statistically significant association was fond between social support from family and relation with health professionals (P = 0.041), difficulties with social and family environment (P = 0.003 and P ≤ 0.001, respectively), and whether they considered themselves as anxious (P = 0.050), and they believed in God (P ≤ 0.001). Furthermore, a statistically significant association was found between support from friends and modification of daily activities (P = 0.010), help in daily activities (P = 0.016), need for movement assistance (P = 0.001), difficulties with social and family environment (P ≤ 0.001 and P = 0.005, respectively), and whether they considered themselves anxious (P = 0.046). Conclusion: Factors associated with perceived social support should be evaluated when planning holistic care to patients with MS.

Background: Carpal tunnel syndrome (CTS) is the most prevalent entrapment syndrome in the upper limbs, for which pregnancy is a known risk factor. CTS diagnosis is confirmed via nerve conduction studies (NCSs), which sometimes is expensive, and the electrical stimulation makes it an unpleasant diagnostic modality, especially for pregnant subjects. Recently, high-frequency ultrasonography (HF-USG) is known as a diagnostic method. This study is concerned with determining the diagnostic value of this modality for CTS among pregnant women. Methods: This cross-sectional case-control study was conducted with 40 CTS cases and 40 matched controls. The HF-USG of wrists was performed bilaterally on all participants with a focus on the median nerve cross-sectional area (MNCSA) at the carpal tunnel (CT) inlet. Results: Mean MNCSA was statistically different between the CTS group (11.71 ± 1.86 mm2, range: 8 to 18 mm2) and the control group (6.75 ± 1.38 mm2, range: 4 to 11 mm2) (P < 0.001). The receiver operating characteristic (ROC) curve was drawn, and the cross-sectional area (CSA) cut-off point of 8.5 mm2 showed sensitivity and specificity of 98% and 93%, respectively. The positive predictive value (PPV) and the negative predictive value (NPV) were 95% and 98%, respectively, with the mentioned point as the diagnostic threshold. Conclusion: HF-USG of the median nerve can be utilized as a preferable alternative to NCS (the current gold standard diagnostic method) in pregnant women, due to its convenience and lower cost, or at least, it can be used as a screening tool among pregnant women with suspicious symptoms.

Background: The aim of this study was to identify the demographic-clinical variables affecting idiopathic epilepsy (IE) [called genetic generalized epilepsy (GGE)] recurrence and determine cut-off values that can be used in pediatric neurology practice for children with IE/GGE. Methods: A total of 250 children and adolescents with IE/GGE were included and retrospectively evaluated. The patients’ hospital records were examined in order to identify possible electro-clinical features affecting epilepsy recurrence. Results: The overall rate of recurrence in the patients was 46%; the age at onset of seizures in recurrence group was lower (P = 0.040) and the age at last seizure was higher in the recurrence group (P < 0.001) than that in the non-recurrence group. Other factors found to be related to recurrence were the shorter duration of the seizure-free period (P = 0.030), shorter interval between the last seizure and antiepileptic drug (AED) withdrawal (P = 0.003), shorter duration of AED withdrawal (P = 0.005), and the existence of abnormalities on sleep electroencephalogram (EEG) during AED withdrawal (P = 0.010) and at the 6th month of withdrawal (P < 0.001). According to receiver operating characteristic (ROC) analysis, the risk of IE recurrence was higher in children who were younger than 3.6 years old (sensitivity: 65.6%, specificity: 62.7%), children with a seizure-free period that was shorter than 35.5 months (sensitivity: 89.6%, specificity: 32.8%), and children whose drug withdrawal period was shorter than 4.5 months (sensitivity: 56.3%, specificity: 71.6%). Conclusion: This study defined some electro-clinical factors that could guide clinicians when deciding to withdraw AEDs with regard to recurrence risk after evaluating a homogenous population of children with a diagnosis of IE/GGE.

Background: The association betweenmedical history and primary progressive multiple sclerosis (PPMS) development has not been well documented in the pertinent literature.The possible association between 23 medical diseases and PPMS occurrence was assessed in the present study. Methods: In order to figure out the possible association between several medical histories and PPMS occurrence, the present population-based case-control study examined 143 PPMS cases in Tehran, Iran, from 2019 to 2020. Diagnosis of PPMS was confirmed by neurologists based on the 2017 McDonald criteria. Sex-matched healthy controls (n = 143) were selected using the random-digit dialing (RDD) technique. Face-to-face and telephone interviews were conducted for gathering the data. The conditional logistic regression model was used to calculate adjusted and unadjusted odds ratio (OR) at a 95% confidence interval (CI). Results: A significant association was found between PPMS development and diseases like depression (OR = 3.12, 95% CI: 1.49-6.53), migraine (OR = 0.19, 95% CI: 0.05-0.67), infectious mononucleosis (OR = 13.16, 95% CI: 2.74-63.17), hypothyroidism (OR = 3.20, 95% CI: 1.23-8.30), and kidney failure (OR = 3.76, 95% CI: 1.41-9.99). Conclusion: Lifetime history of depression, infectious mononucleosis, hypothyroidism, and kidney failure might increase the risk of PPMS development, while individuals with positive history of migraine disease are at lower risk for developing PPMS.

Background: Post-dural puncture headache (PDPH) is a common problem after spinal anesthesia. Depending on the severity of PDPH, there are both invasive and non-invasive treatments. Caffeine has been used for the treatment of PDPH since 1949, but the administration of mannitol is a novel management to tackle PDPH.This study was conducted to compare the effectiveness of acetaminophen-caffeine and mannitol in the treatment of PDPH. Methods: We enrolled 80 patients with PDPH in the present clinical trial and observed them during 72 hours after cesarean section. Participants were randomly and equally allocated to two groups for treatment with intravenous (IV) mannitol or oral acetaminophen-caffeine. The effects of treatment were evaluated using the visual analogue scale (VAS) questionnaire at hours of 1, 2, 3, 4, 6, 12, 18, 24, and 48. SPSS software was used. Results: Forty patients in each group completed the study. There was a significant reduction in the pain scores of the both groups after treatment, but the interaction between time and group demonstrated that mannitol administration was superior to acetaminophen-caffeine in pain reduction of the patients undergoing spinal anesthesia (P = 0.028). Patients’ satisfaction in the mannitol group was significantly higher than the caffeine group (P = 0.001). Conclusion: This study suggests that IV mannitol infusion affects faster and earlier for the treatment of PDPH than acetaminophen-caffeine capsule. Mannitol could be probably more effective for treatment of PDPH.

Background: Generalized anxiety disorder (GAD) often remains undiagnosed in patients with migraine, while comorbidity of GAD with migraine is associated with increased dysfunction and risk of chronic migraine. Generalized Anxiety Disorder Scale 7-item (GAD-7) and Generalized Anxiety Disorder Scale 2-item (GAD-2) are the commonly employed screening measures for generalized anxiety symptoms in different patient groups. The present study aimed to evaluate psychometric properties of the Persian version of GAD-7 and GAD-2 in migraine. Methods: In this cross-sectional study, patients were diagnosed with migraine headaches according to the International Classification of Headache Disorders, 3rd edition (ICHD-3); then they participated in the psychiatric diagnostic interview, and filled out GAD-7, GAD-2, Beck Anxiety Inventory (BAI), Headache Impact Test-6 (HIT-6), and Migraine-Specific Quality of Life Questionnaire version 2.1 (MSQv2.1). The psychometric properties of GAD-7 and GAD-2 were examined using SPSS and LISREL. Results: Final samples were 186 patients with migraine that 83 patients received a diagnosis of GAD. Confirmatory factor analysis (CFA) indicated that the one-factor model of GAD-7 fit the data well. Internal consistency, test-retest, and Guttman split-half reliability of GAD-7 and GAD-2 were good. Significant correlation results, average variance extracted (AVE), and composite reliability (CR) supported the construct validity of the GAD-7. A score of ≥ 10 in GAD-7 and ≥ 3 in GAD-2 achieved satisfactory sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) (GAD-7: 92%, 90%, 88%, and 93%, respectively; GAD-2: 79%, 88%, 71%, and 91%, respectively). Conclusion: Our findings supported GAD-7 and GAD-2 for assessing GAD in patients with migraine. It seems that GAD-7 and GAD-2 accurately diagnosed GAD in this group of patients.
