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: Amyotrophic Lateral Sclerosis-Specific Quality of Life-Revised (ALSSQOL-R) encompasses 50 items which assess quality of life (QOL) in patients with amyotrophic lateral sclerosis (ALS) in six major domains. This study aims to translate the ALSSQOL-R into Persian and evaluate its reliability and validity among Iranian patients. Methods: ALSSQOL-R was translated by the standard multi-step forward-backward method. Content validity was calculated using item content validity index (I-CVI). Three items in the “intimacy” domain were deleted considering Iranian culture. Cronbach’s alpha was used for all 6 dimensions to calculate the internal consistency reliability. Test-retest reliability was evaluated using intraclass correlation coefficient (ICC) with one-month interval. Concurrent validity was measured by the validated version of 36-Item Short Form Health Survey (SF-36) questionnaire. Results: Sixty-three patients with ALS were enrolled in the study. I-CVI was 70%, promoted to 85% after modifications (acceptable). Regarding internal consistency reliability, Cronbach’s alpha in all six domains was ³ 0.70 and total Cronbach’s alpha was 0.89 which is assumed as good. In terms of test-retest reliability, ICC [95% confidence interval (CI)] was 0.91 (91%) and Pearson correlation coefficient (r) was 0.90 (P < 0.001), all indicating an excellent reliability. The concurrent validity was established based on a strong correlation with SF-36 (r = 0.744, P < 0.001). Conclusion: The findings show that the modified Persian version of ALSSQOL-R is a valid and reliable QOL questionnaire which can be used for Iranian patients with ALS in both clinical and research settings.

Background: Few studies have reported the association of Guillain-Barre syndrome (GBS) and coronavirus disease-2019 (COVID-19) infection. In this study, we reported GBS in six patients infected with COVID-19 and reviewed all existing literature about GBS in association with COVID-19. Methods: This study was performed in three referral centers of COVID-19 in Iran, and six patients with the diagnosis of GBS were enrolled. Patients enrolled in the study with acute progressive weakness according to the demyelinating or axonal variant of GBS, according to Uncini's criteria. Results: Four of our patients had axonal polyneuropathy, two patients had demyelinating polyneuropathy, and one patient required mechanical ventilation. All our patients had a favorable response to treatment. In one patient, the GBS symptoms recurred four months after the first episode. Conclusion: Limited case reports suggest a possible association between GBS and COVID-19. Such associations may be an incidental concurrence or a real cause-and-effect linkage; however, more patients with epidemiological studies are necessary to support a causal relationship.

Background: The objective of our study was to assess Unified Parkinson Disease Rating Scale (UPDRS) score in Parkinson disease (PD) patients who underwent subthalamic nucleus (STN) deep brain stimulation (DBS) 6 years after their surgery and to compare their UPDRS score 6 years after DBS with their score before surgery and 6 months after their operation.Methods: In this cross sectional study which was carried out at Neurology Department of Rasool-e-Akram Hospital, Tehran, Iran, affiliated to Iran University of Medical Sciences between 2008 and 2014, 37 patients with advanced PD were enrolled using non-randomized sampling method. All of the patients underwent STN DBS surgery and one patient died before being discharged, therefore; we started our study with 36 patients. The UPDRS III total score at preoperative state, 6-month follow-up and 6-year follow-up state were compared using repeated-measure analysis of variance.Results: Thirty-seven patients (26 men and 10 women) with mean age of 50 ± 3 ranging from 32 to 72 years underwent STN DBS surgery. All patients were suffering from advanced PD with mean period of 11.3 ± 1.9 years. All patients except one were followed up for six months. And 14 patients (8 men and 6 women) were included in a six-year follow-up. The UPDRS score measurements before surgery, at 6-month follow-up and 6-year follow-up were 18.22 ± 2.88, 12.80 ± 3.14, 25.0 ± 11.8, respectively. Significant increase in UPDRS score was observed between the preoperative and six-year follow-up period (P < 0.001).Conclusion: In conclusion, this study suggests that total UPDRS score will increase at 5 years following STN DBS and also showed that resting tremor, one of UPDRS sub-scores, will improve over time and the benefit of DBS will be persistent even after 6 years.
