The role of transcranial direct current stimulation in diminishing the risk of pneumonia in patients with dysphagia: A double-blinded randomized clinical trial.

Background: Dysphagia can be a life-threatening issue for post-stroke patients, with aspiration pneumonia (AP) being a common risk. However, there is hope through the potential combination of transcranial direct current stimulation (tDCS) and classical behavior therapy. Our study aims to investigate the effectiveness of this combination in diminishing the risk of AP in patients with dysphagia who suffered from stroke. Methods: In this randomized, parallel-group, blinded clinical trial, 48 patients were allocated into the sham group (speech therapy + 30 seconds of tDCS) and the real group (speech therapy + 20 minutes of tDCS). We used the Mann Assessment of Swallowing Ability (MASA) as an assessment tool. We assessed patients at baseline, one day after treatment, and at a one-month follow-up. Results: Groups showed no significant difference at baseline. After treatment, the real group showed a significant difference in the severity risk of AP (P = 0.02); the same was for the follow-up (P = 0.04). The number of patients showing severe risk of AP was higher in the sham group after treatment (n = 13, 54.20%) and at follow-up (n = 4, 18.20%) than the real group (n = 4, 16.70%; n = 1, 4.50%, respectively). None of the patients reported the history of AP at any stage of assessment. Conclusion: Although the results were more promising in the real group than the sham group in reducing the risk of AP, both techniques can prevent AP. Therefore, we recommend early dysphagia management to prevent AP regardless of the treatment protocol.

The hospitalization rate and clinical characteristics of mucormycosis prior and during COVID-19 pandemic: A single-center study.

INTRODUCTION: There have been some reports of the association between SARS-CoV-2 infection and mucormycosis. This study aims to compare the hospitalization rates and clinical characteristics of mucormycosis before and during the COVID-19 pandemic. METHODOLOGY: In this retrospective study, we compared the hospitalization rate of mucormycosis patients in Namazi hospital in Southern Iran for two periods of 40 months. We defined July 1st, 2018 to February 17th, 2020, as the pre-COVID-19 period and February 18th, 2020, to September 30th, 2021, as the COVID-19 period. In addition, a quadrupled group of hospitalized patients with age and sex-matched SARS-COV-2 infection without any sign of mucormycosis was selected as the control group for COVID-associated mucormycosis. RESULT: In the total of 72 mucormycosis patients in the COVID period, 54 patients had a clinical history and a positive RT-PCR, which confirms the diagnosis of SARS-COV2 infection. The hospitalization rate of mucormycosis showed an increase of + 306% (95% CI: + 259%, + 353%) from a monthly average value of 0.26 (95% confidence interval (CI): 0.14, 0.38) in the pre-COVID period to 1.06 in the COVID period. The use of corticosteroids prior to the initiation of hospitalization (p ≤ 0.01), diabetes (DM) (p = 0.04), brain involvement (p = 0.03), orbit involvement (p = 0.04), and sphenoid sinus invasion (p ≤ 0.01) were more common in patients with mucormycosis during the COVID period. CONCLUSIONS: In high-risk patients, especially diabetics, special care to avoid the development of mucormycosis must be taken into account in patients with SARS-COV-2 infection considered for treatment with corticosteroids.

Clinical characteristics, radiological features and prognostic factors of transverse myelitis following COVID-19 vaccination: A systematic review.

BACKGROUND: Since introducing COVID-19 vaccines, many neurological complications such as acute transverse myelitis have been reported in the literature. This study aims to identify the clinical characteristics, radiological findings, and prognostic factors in patients with COVID-19 vaccine-associated transverse myelitis (TM). METHODS: We systematically reviewed Scopus, Pubmed, Cochrane library, Google Scholar, and preprint databases using appropriate keywords from inception till 8th April 2022. Besides, we manually searched the reference lists of the included studies and relevant previous reviews. RESULTS: We included 28 studies identifying 31 post-COVID-19 vaccination myelitis patients (17 female and 14 male). The mean age of the included patients was 52±19 years. ChAdOx1 nCoV-19 vaccine (Oxford-AstraZeneca) was the most common type of vaccine in association with myelitis (12 out of 31), followed by Pfizer (8 out of 31), Moderna (7 out of 31), Sinopharm (3 out of 31), and Janssen vaccine (1 out of 31). The myelitis occurred in 24 and 7 patients after administering the first and second dose of the vaccine, respectively. 21 and 10 patients had good recovery (Modified Rankin Score (MRS) <3 at the follow-up) and poor recovery (MRS≥3 at the follow-up) from myelitis, respectively. Age (OR 1.09, 95%CI 1.01-1.18, pvalue 0.02), and MRS at admission (OR 17.67, 95%CI 1.46-213.76, pvalue 0.024) were two independent risk factors for poor recovery from myelitis. CONCLUSION: The patients with higher age and MRS at admission had a worse prognosis and needed timely and more aggressive therapeutic strategies.

Treatment of Child Gratification Disorder.

Objectives: Gratification disorder is a group of self-stimulatory behaviors tending to form a habit. These normal behaviors are common and have various differential diagnoses, including epilepsy. Hence, misdiagnosis may lead to performing unnecessary workups and treatments. In this article, we systematically reviewed available treatment options for gratification disorder. Materials & Methods: We systematically searched Scopus, MEDLINE, and Embase for related articles published from the beginning to 12th May 2021. We followed the search strategy in all electronic databases using keywords ["Self-gratification" AND "treatment"], ["child" AND "masturbation" AND "treatment"], ["Pediatric" AND "masturbation" AND "treatment"], ["infantile" AND "masturbation" AND "treatment"], and ["Benign" AND "Infantile" AND "Dyskinesia" AND "treatment"]. Results: The primary search yielded 241 studies. Five studies fulfilled the inclusion criteria and were used in the systematic review. None of the studies provided a good level of evidence. These studies indicated that behavioral therapy, escitalopram, and aripiprazole could be considered treatment options. Conclusion: Although pediatricians are familiar with gratification behaviors, their optimal management is overlooked. In addition to parental education and behavioral therapy, escitalopram and aripiprazole can be used as treatment options for this issue. We need to perform well-designed randomized controlled trials to obtain adequate evidence on the efficacy of these measures.

Seizure and social outcomes in patients with juvenile myoclonic epilepsy (JME).

OBJECTIVES: To investigate the seizure outcome in patients with juvenile myoclonic epilepsy (JME) and its associated factors. We also investigated the social outcome of these patients. METHODS: This was a retrospective study. All patients with a diagnosis of JME were studied at the outpatient epilepsy clinic at Shiraz University of Medical Sciences, Shiraz, Iran, from 2008 until 2019. In a phone call to the patients, at least 24 months after their diagnosis at our center, we investigated their current seizure control state and social status. RESULTS: One hundred and thirty-five patients were studied [92 women (68.1%) and 43 men (31.9%)]. Fifty-three patients (39.3%) were seizure-free (of all seizure types) during the past 12 months; 91 patients (67.4%) reported to be free of generalized tonic-clonic seizures. At the time of the follow-up call, 71 patients (52.6%) reported having a college education, 56 patients (41.5%) were employed, 87 patients (64.4%) were married, and 57 patients (42.2%) reported driving a motor vehicle in their routine daily lives. In total, 101 patients (74.8%) reported that their status (generally, and considering all the variables) was better than that it used to be five years ago. CONCLUSION: We may conclude that JME at tertiary referral centers is not as benign as it was suggested by some authors before. Furthermore, the employment status of patients with JME is significantly worse than that in the corresponding general populations. However, most patients with JME may enjoy marital status and educational levels comparable to those by the general public.

Long COVID syndrome-associated brain fog.

We investigated the frequency of brain fog in a large cohort of patients with documented coronavirus disease-2019 (COVID-19) who have survived the illness. We also scrutinized the potential risk factors associated with the development of brain fog. Adult patients (18-55 years of age), who were referred to the healthcare facilities anywhere in Fars province from February 19, 2020 to November 20, 2020 were included. All patients had a confirmed COVID-19 diagnosis. In a phone call, at least 3 months after their discharge from the hospital, we obtained their current information. A questionnaire was specifically designed for data collection. In total, 2696 patients had the inclusion criteria; 1680 (62.3%) people reported long COVID syndrome (LCS). LCS-associated brain fog was reported by 194 (7.2%) patients. Female sex (odds ratio [OR]: 1.4), respiratory problems at the onset (OR: 1.9), and intensive care unit (ICU) admission (OR: 1.7) were significantly associated with reporting chronic post-COVID "brain fog" by the patients. In this large population-based study, we report that chronic post-COVID "brain fog" has significant associations with sex (female), respiratory symptoms at the onset, and the severity of the illness (ICU admission).

Risk Factors Associated with Long COVID Syndrome: A Retrospective Study.

Background: Recently, people have recognized the post-acute phase symptoms of the COVID-19. We investigated the long-term symptoms associated with COVID-19, (Long COVID Syndrome), and the risk factors associated with it. Methods: This was a retrospective observational study. All the consecutive adult patients referred to the healthcare facilities anywhere in Fars province from 19 February 2020 until 20 November 2020 were included. All the patients had a confirmed COVID-19 diagnosis. In a phone call to the patients, at least three months after their discharge from the hospital, we obtained their current information. The IBM SPSS Statistics (version 25.0) was used. Pearson Chi square, Fisher's exact test, t test, and binary logistic regression analysis model were employed. A P value of less than 0.05 was considered to be significant. Results: In total, 4,681 patients were studied, 2915 of whom (62.3%) reported symptoms. The most common symptoms of long COVID syndrome were fatigue, exercise intolerance, walking intolerance, muscle pain, and shortness of breath. Women were more likely to experience long-term COVID syndrome than men (Odds Ratio: 1,268; 95% Confidence Interval: 1,122-1,432; P=0.0001), which was significant. Presentation with respiratory problems at the onset of illness was also significantly associated with long COVID syndrome (Odds Ratio: 1.425; 95% Confidence Interval: 1.177-1.724; P=0.0001). A shorter length of hospital stay was inversely associated with long COVID syndrome (Odds Ratio: 0.953; 95% Confidence Interval: 0.941-0.965; P=0.0001). Conclusion: Long COVID syndrome is a frequent and disabling condition and has significant associations with sex (female), respiratory symptoms at the onset, and the severity of the illness.

Educational needs of physicians (in training) for management of patients with epilepsy.

OBJECTIVES: To investigate the opinions of medical students, residents in different disciplines, and clinical attendings in various disciplines on the educational needs and learning objectives about epilepsy at the basic and intermediate levels of medical education. METHODS: On July 15th, 2021, we posted an online invitation including a questionnaire to all the medical students, residents, and attendings of Shiraz University of Medical Sciences, Iran. The survey anonymously collected data about the participants [sex, age, educational level, and their disciplines (attendings)], and answers to the questions about their opinions about the educational needs and learning objectives of the medical students and residents about epilepsy. RESULTS: Five hundred and seventy-eight trainees and 53 attendings participated in the study. Trainees at different educational levels and in various disciplines had significantly different opinions on their educational needs and learning objectives about epilepsy. At the undergraduate level, the opinions of the trainees and their attendings were similar and the most reported needs by both groups included: Terminology and definitions, Physiopathology and etiology, Semiology and clinical characteristics, Medical treatment, Comorbidities. For the residents in neurology, psychiatry, and neurosurgery, the most reported needs included: all aspects of epilepsy. SIGNIFICANCE: Trainees at various educational levels/disciplines in medicine have different educational needs and learning objectives with regard to epilepsy and management of PWE. Policy makers in medical education should consider the observations of this study in order to design tailored and targeted educational curricula about epilepsy for various educational levels/disciplines in medicine.

Safety and Outcomes of Intravenous Thrombolytic Therapy in Ischemic Stroke Patients with COVID-19: CASCADE Initiative.

BACKGROUND: There is little information regarding the safety of intravenous tissue plasminogen activator (IV-tPA) in patients with stroke and COVID-19. METHODS: This multicenter study included consecutive stroke patients with and without COVID-19 treated with IV-tPA between February 18, 2019, to December 31, 2020, at 9 centers participating in the CASCADE initiative. Clinical outcomes included modified Rankin Scale (mRS) at hospital discharge, in-hospital mortality, the rate of hemorrhagic transformation. Using Bayesian multiple regression and after adjusting for variables with significant value in univariable analysis, we reported the posterior adjusted odds ratio (OR, with 95% Credible Intervals [CrI]) of the main outcomes. RESULTS: A total of 545 stroke patients, including 101 patients with COVID-19 were evaluated. Patients with COVID-19 had a more severe stroke at admission. In the study cohort, 85 (15.9%) patients had a hemorrhagic transformation, and 72 (13.1%) died in the hospital. After adjustment for confounding variables, discharge mRS score ≥2 (OR: 0.73, 95% CrI: 0.16, 3.05), in-hospital mortality (OR: 2.06, 95% CrI: 0.76, 5.53), and hemorrhagic transformation (OR: 1.514, 95% CrI: 0.66, 3.31) were similar in COVID-19 and non COVID-19 patients. High-sensitivity C reactive protein level was a predictor of hemorrhagic transformation in all cases (OR:1.01, 95%CI: 1.0026, 1.018), including those with COVID-19 (OR:1.024, 95%CI:1.002, 1.054). CONCLUSION: IV-tPA treatment in patients with acute ischemic stroke and COVID-19 was not associated with an increased risk of disability, mortality, and hemorrhagic transformation compared to those without COVID-19. IV-tPA should continue to be considered as the standard of care in patients with hyper acute stroke and COVID-19.

Long COVID in children and adolescents.

BACKGROUND: To identify the prevalence and also the full spectrum of symptoms/complaints of children and adolescents who are suffering from long COVID. Furthermore, we investigated the risk factors of long COVID in children and adolescents. METHODS: All consecutive children and adolescents who were referred to the hospitals anywhere in Fars province, Iran, from 19 February 2020 until 20 November 2020 were included. All patients had a confirmed diagnosis of COVID-19. In a phone call to patients/parents, at least 3 months after their discharge from the hospital, we obtained their current status and information if their parents agreed to participate. RESULTS: In total, 58 children and adolescents fulfilled the inclusion criteria. Twenty-six (44·8%) children/adolescents reported symptoms/complaints of long COVID. These symptoms included fatigue in 12 (21%), shortness of breath in 7 (12%), exercise intolerance in 7 (12%), weakness in 6 (10%), and walking intolerance in 5 (9%) individuals. Older age, muscle pain on admission, and intensive care unit admission were significantly associated with long COVID. CONCLUSIONS: Long COVID is a frequent condition in children and adolescents. The scientific community should investigate and explore the pathophysiology of long COVID to ensure that these patients receive appropriate treatments for their condition.

Seizure and social outcomes in patients with non-surgically treated temporal lobe epilepsy.

OBJECTIVES: To investigate the seizure outcome with medical treatment in patients with temporal lobe epilepsy (TLE) and its associated factors. We also investigated the social outcome of the patients. METHODS: This was a retrospective study of a prospectively built electronic database of patients with epilepsy. All patients with a diagnosis of TLE were studied at the outpatient epilepsy clinic at Shiraz University of Medical Sciences, Shiraz, Iran, from 2008 until 2019. In a phone call to the patients, at least 24 months after their diagnosis at our center, we investigated their current seizure control and social status. RESULTS: Two hundred and twenty-two patients were studied; 101 patients (45.5%) were seizure free. A lower number of the prescribed drugs was the only factor with a significant association with the seizure-free outcome (Odds Ratio: 1.460; p = 0.001). At the time of the phone call, 76 patients (37.6%) reported having a college education, 103 patients (51%) were employed, 146 patients (72.3%) were married, and 81 patients (40%) reported driving a motor vehicle. The employment status, college education, and driving a motor vehicle were significantly associated with a seizure-free outcome status. The social achievements of the patients, who were partially responsive to medical therapy, were significantly worse than those who were seizure free. CONCLUSION: Many patients with TLE may suffer from drug-resistant seizures. Ongoing seizures in these patients may affect their social lives substantially. Seizure reduction (not freedom) is not good enough to help the patients with TLE enjoy a healthy life with satisfactory social achievements.
