Background: Headaches are one of the most common neurological disorders, ranging in severity from mild discomfort to a severe, debilitating condition. Headaches are particularly prevalent among medical students, which can be attributed to various factors such as psychological stressors, extensive studying, long hours of clinical rotations and high-pressure examination. This study aims to ascertain the prevalence of different types of headaches, along with analysing their associated clinical characteristics among medical students in Egypt., Methods: A multicentric, descriptive questionnaire-based cross-sectional study was conducted across five governmental faculties of medicine in Egypt from November 2022 to March 2023. Using a multistage random sampling method, 600 undergraduate students were selected to participate. Headache was diagnosed based on the International Classification of Headache Disorders., Results: A total of 493 responses were included in the analysis; the prevalence of headache disorder was 264 (53.5%), with tension-type headaches (TTH) frequent episodic being the highest 89 (33.7%), while TTH chronic and migraine with aura were the least prevalent, accounting for 10 (3.8%) and 31 (11.7%), respectively. Women exhibited a higher overall headache prevalence (69.4%) compared with men (44.4%). A positive family history was found in 120 (45.5%) of students with headache. Lack of sleep and stress were the most frequently reported potential triggers for headaches. Out of 264 medical students, 171 (65%) took analgesics. Only 42 (24.6%) had a medical consultation, while most students 129 (75.4%) took over-the-counter medications., Conclusion: Notably, headaches were prevalent in 264 (53.5%) of the respondents. TTH frequent and infrequent emerged as the most common headaches among medical students, followed by migraine without aura then migraine with aura. Participants were statistically different according to sex, faculty, academic year and living conditions. Alarmingly, despite the substantial prevalence, only 42 (24.6%) students sought medical consultation., Competing Interests: None declared., (Copyright © Author(s) (or their employer(s)) 2024.

Aims: This systematic review and meta-analysis aimed to determine the annual incidence rate of venous thromboembolism (VTE) and identify risk factors of VTE in amyotrophic lateral sclerosis (ALS) patients., Methods: A comprehensive search of three databases was conducted up to April 8, 2024, to identify longitudinal studies reporting VTE incidence in ALS patients. The included studies were either prospective or retrospective, following up with ALS patients. Quality assessment was performed using the NIH tool for observational cohort studies. Meta-analysis was conducted using Open Meta Analyst, employing a random-effect model. Subgroup, Meta-regression, and sensitivity analyses were also carried out., Results: Our analysis included eight studies comprising a total of 26,758 ALS patients that met the inclusion criteria. The pooled annual incidence of VTE across all studies was found to be 22 cases per 1,000 person-year (95% CI = 18 to 27). Subgroup analysis revealed that the annual incidence of VTE in males was 19 cases per 1,000 person-year (95% CI = 15 to 22), while in females, it was 20 cases per 1,000 person-year (95% CI = 16 to 25). Leave-one-out analysis demonstrated that the incidence ranged from 21 to 28 cases per 1,000 person-year when excluding each study individually. Meta-regression analysis did not find a significant association between age and the risk of VTE (P = 0.079). Based on the included studies, risk factors of VTE in ALS patients included a history of VTE, non-invasive ventilation, immobility, and decreased functional status., Conclusion: Patients with ALS face a higher risk of developing VTE compared to individuals of the same age. These findings underscore the importance of implementing preventive measures and closely monitoring VTE in ALS patients.

Background: Cerebrovascular diseases of the brain are usually defined by transient ischemic attacks and strokes. However, they can also cause brain injuries without neurological events. Silent brain infarcts (SBI) and leukoaraiosis are symptoms of both vascular and neurological abnormalities. This study aims to investigate the association between SBI, leukoaraiosis, and middle-aged patients with ischemic stroke., Methods: A single-center retrospective study of 50 middle-aged, ischemic stroke patients were studied from November 2022 and May 2023. The patients were divided into two groups based on the presence or absence of leukoaraiosis. History taking, physical examination, brain CT scan, and MRI were all part of the diagnostic process. Metabolic syndrome (MetS) was also assessed through various factors. The statistical analysis included descriptive statistics, logistic regression analysis, and chi-square test., Results: Out of the cohort comprising 50 patients, characterized by a mean age of 52.26 years (SD 5.29), 32 were male, constituting 64% of the sample. Among these patients, 26 individuals exhibited leukoaraiosis, with 17 of them (65.4%) also presenting with SBI. Moreover, within this cohort, 22 patients were diagnosed with MetS, representing 84.6% of those affected. The Multivariate logistic regression analysis showed a strong and independent association between leukoaraiosis and SBI. Individuals with leukoaraiosis were nearly five times more likely to have SBI compared to those without leukoaraiosis., Conclusion: The study highlights leukoaraiosis as a significant risk factor for SBI, alongside MetS. Advanced imaging techniques have facilitated their detection, revealing a higher prevalence among stroke patients, particularly associated with age and hypertension. Further research is needed to fully understand their complex relationship and develop better management strategies for cerebrovascular diseases, ultimately improving patient outcomes., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Abdulsalam, Shaheen, Shaheen, Alabdallat, Ramadan, Meshref, Mansour, Abed, Fayed, Zaki, El-Adawy, Flouty and Hamed.)

Background and Purpose: Repetitive transcranial magnetic stimulation (rTMS) of the cerebellar hemisphere represents a new option in treating essential tremor (ET) patients. We aimed to determine the efficacy of cerebellar rTMS in treating ET using different protocols regarding the number of sessions, exposure duration, and follow-up duration., Methods: A randomized sham-controlled trial was conducted, in which 45 recruit patients were randomly allocated to 2 groups. The first (active group) comprised 23 patients who were exposed to 12 sessions of active rTMS with 900 pulses of 1-Hz rTMS at 90% of the resting motor threshold daily on each side of the cerebellar hemispheres over 4 weeks. The second group (sham group) comprised 22 patients who were exposed to 12 sessions of sham rTMS. Both groups were reassessed at baseline and after 1 day, 1 month, 2 months, and 3 months using the Fahn-Tolosa-Marin tremor-rating scale (FTM)., Results: Demographic characteristics did no differ between the two groups. There were significant reductions both in FTM subscores A and B and in the FTM total score in the active-rTMS group during the period of assessment and after 3 months ( p =0.031 and 0.011, respectively). However, subscore C did not change significantly from baseline when assessed at 2 and 3 months ( p =0.073 and 0.236, respectively). Furthermore, the global assessment score was significantly higher in the active-rTMS group ( p >0.001)., Conclusions: Low-frequency rTMS over the cerebellar cortex for 1 month showed relative safety and long-lasting efficacy in patients with ET. Further large-sample clinical trials are needed that include different sites of stimulation and longer follow-ups., Competing Interests: The authors have no potential conflicts of interest to disclose., (Copyright © 2024 Korean Neurological Association.)

COVID-19, or coronavirus infection, is an acute respiratory illness caused by the corona virus that can develop into a life-threatening form of ARDS. Extracorporeal membrane oxygenation (ECMO) is a highly effective treatment for life-threatening instances. One of the many complications associated with ECMO was bleeding. COVID patients are at risk for intracerebral bleeding due to several factors, including the drug's action on ACE2 receptors, leading to hypertension, as well as hypercoagulability, dysregulated immune response, DIC, and the use of anticoagulants., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2023 2020 International Hemorrhagic Stroke Association.

Background: Gaming addiction is a compulsive mental health condition that can have severe negative consequences on a person's life. As online gaming has increased during the COVID-19 pandemic, studies have shown a heightened risk of mental health issues. This study aims to assess the prevalence of severe phobia and addiction to online gaming among Arab adolescents and identify risk factors associated with these disorders., Methods: This cross-sectional study was conducted across 11 Arab nations. Participants were recruited using convenience sampling through an online survey distributed on social media platforms in 11 Arab countries. The survey included demographic questions, the Nine-item Internet Gaming Disorder Scale-Short Form (IGDS-SF9) to measure participants' online gaming addiction, the Social Phobia Scale (SPS), and questions assessing the impact of the COVID-19 pandemic on the prevalence of internet gaming addiction. The data were analyzed using SPSS win statistical package version 26., Results: Out of 2,458 participants, 2,237 were included in the sample due to non-response and missing data. The average age of the participants was 19.9 ± 4.8 years, and the majority were Egyptian and unmarried. 69% of the participants reported playing more than usual since the COVID-19 pandemic, as they were confined to their homes. Higher social phobia scores were associated with being single, male, and Egyptian. Participants from Egypt and those who felt that the pandemic significantly increased their gaming time had higher scores for online gaming addiction. Several major criteria, such as playing hours per day and beginning gaming at an early age, were associated with a higher level of online gaming addiction with social phobia., Conclusion: The study's findings suggest that there is a high prevalence of internet gaming addiction among Arab adolescents and young adults who play online games. The results also indicate a significant association between social phobia and several sociodemographic factors, which may inform future interventions and treatments for individuals with gaming addiction and social phobia., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Shaheen, Shaheen, Elmasry, Abdelwahab, Mohamed, Swed, Rababah, Meshref, Zaki and Shoib.)

Introduction: Vertebral artery dissection (VAD) is a rare, but life-threatening condition. Compared to the general population, pregnant and postpartum women are more likely to develop VAD. Spontaneous arterial dissections have an ambiguous pathophysiology and may be difficult to manage. This study aimed to pool and analyze the data of published cases in this regard., Methods: We conducted a literature search on February 24, 2022, using MeSH terms of interest in PubMed, Google Scholar, Ovid, Web of Science, and Scopus databases to find studies on VAD following childbirth., Results: A total of 28 studies were included in this review based on a database search. In the studies, 44 postpartum VAD (PPVAD) patients with a mean age of 34.26 ± 3.5 years were included. It took an average of 24.37± 13.7 days from delivery to dissection. 64% of the patients had developed unilateral dissection and 36% had developed bilateral dissection; 70% reported full recovery, and 9% did not achieve full recovery. The most common symptoms were headaches (89%), neck pain (64%), and hypertension (52%). The most common methods of diagnosis were magnetic resonance imaging (MRI) (64%) and computed tomography (CT) angiography (CTA) scan (66%). Only 8 (18%) cases reported the use of electrocardiography (ECG). The recorded outcomes of the patients with unilateral and bilateral postpartum VAD showed no statistical difference. Most of the included studies recommend early suspension and management for a better prognosis and prevention of complications., Conclusion: PPVAD is a severe medical condition but most cases were fully recovered after an early and proper antithrombotic plan for each case scenario., Competing Interests: The authors have no conflict of interest to declare

Background: Covid-19 has serious sequelae that may be poorly understood, underreported, and, as a result, not diagnosed promptly, such as variations in clinical manifestations of hyperinflammation among people infected with SARS-CoV-2. ophthalmoplegia can be one of these manifestations., Methods: We are reporting a 55-year-old male patient with unilateral diplopia considering it as a case of multisystem inflammatory syndrome in adults. We also reviewed the literature systematically for the previously reported studies/cases with third, fourth and sixth cranial nerve palsies due to or after Covid-19., Results: The literature search yielded 17 studies reporting 29 patients. 71.4% of the patients were males with a mean age of 42.23 years. Ophthalmological symptoms took 9.7 days to appear after the respiratory involvement. All patients had diplopia as part of their visual symptoms. 41.4% of the patients had unilateral sixth nerve palsy, 24% had bilateral sixth nerve involvement, 17% had fourth nerve involvement, and 27.6% had third nerve involvement., Conclusion: Ophthalmoplegia is considered presenting symptom of Covid-19. Further research is needed to detect all neuro-ophthalmological manifestations of Covid-19., Competing Interests: The authors have no funding and conflicts of interest to disclose., (Copyright © 2022 the Author(s).

Introduction: Takotsubo cardiomyopathy (TCM) mimics acute coronary syndrome and is characterized by reversible left ventricular (LV) apical ballooning in the absence of angiographically substantial coronary artery stenosis., Patient Concerns: A 31-year-old man with acute dejection, physical stress, and psychological strain from the dread of losing his work arrived at the emergency department with chest pain, and discomfort that had lasted 3 hours., Diagnosis: Once the coronary angiography revealed normal epicardial coronaries, the case was retroactively diagnosed, and the levels of cardiac enzymes were increased., Interventions: The amount of necrotic tissue was so little that the surgeon could only verbally convey it. It is completely closed with the help of a Dacron sheet. The patient received surgical closure of the VSR a few days after having a surgical consultation., Outcomes: No postoperative echocardiogram was required, and the patient was sent home in great general condition., Conclusion: The presence of TCM with a ruptured LV wall was extremely rare because our patient had neither clinical risk indicators nor a family history of coronary artery disease. As a Takotsubo syndrome severe complication, we underline the significance of identifying, diagnosing, and treating it., Competing Interests: The authors have no funding and conflicts of interest to disclose., (Copyright © 2022 the Author(s).

With over 58 million cases and 6 million deaths by August 2022, the Coronavirus disease 2019 (COVID-19), causing severe acute respiratory syndrome coronavirus 2 (SARs-CoV-2), has had an insurmountable impact on the world's population. This is one of the worst health crises since 1918's influenza pandemic. There are four subvariants of Omicron; BA.1, BA.1.1, BA.2 and BA.3. As a result of new mutations in its spike protein, most of which occur in its receptor binding site, the Omicron variant appears to be more transmissible and less resistant to vaccination and antibody response. Understanding Omicron's virology and mutations is essential to developing diagnostic and therapeutic methods. A thorough assessment of control measures, as well as timely adjustment of control measures, requires addressing such issues as re-infection risk, vaccine response, booster vaccine doses, and the increased rate of Omicron infections. This review article aims to look at the current information about the different types of SARs-CoV-2, focusing on the new subtype BA.2.75., Competing Interests: Dr Mahmoud Tarek Hefnawy reports non-financial support from Zagazig University Faculty of Medicine, during the conduct of the study.

The Monkeypox virus (MPXV) is a double-stranded DNA virus related to the orthopoxvirus genus in the family of poxviridae. MPXV is endemic in central and Western African countries. There have been several outbreaks of MPXV in non-endemic countries since it was discovered in 1958 in lab monkeys. The current spread of MPXV is different from previous outbreaks, raising concerns about its potential to cause pandemics around the world. In order to reduce the spread of the disease, several countries imposed different preventive measures. The MPXV virus is believed to be transmitted either through wild animals, such as rodents or through infected individuals. Every year, Africa experiences a few thousand cases, mostly in the west and central regions. The number of cases outside Africa has previously been limited to a handful associated with travel to Africa or with the importation of infected animals. In this narrative review, we will discuss the clinical diagnosis, transmission, distribution, treatment, and prevention of the recent monkeypox outbreak around the world., Competing Interests: All authors have no conflict of interest to disclose., (© 2022 The Authors.)

Gliomas, which account for nearly a quarter of all primary CNS tumors, present significant contemporary therapeutic challenges, particularly the highest-grade variant (glioblastoma multiforme), which has an especially poor prognosis. These difficulties are due to the tumor's aggressiveness and the adverse effects of radio/chemotherapy on the brain. Stem cell therapy is an exciting area of research being explored for several medical issues. Neural stem cells, normally present in the subventricular zone and the hippocampus, preferentially migrate to tumor masses. Thus, they have two main advantages: They can minimize the side effects associated with systemic radio/chemotherapy while simultaneously maximizing drug delivery to the tumor site. Another feature of stem cell therapy is the variety of treatment approaches it allows. Stem cells can be genetically engineered into expressing a wide variety of immunomodulatory substances that can inhibit tumor growth. They can also be used as delivery vehicles for oncolytic viral vectors, which can then be used to combat the tumorous mass. An alternative approach would be to combine stem cells with prodrugs, which can subsequently convert them into the active form upon migration to the tumor mass. As with any therapeutic modality still in its infancy, much of the research regarding their use is primarily based upon knowledge gained from animal studies, and a number of ongoing clinical trials are currently investigating their effectiveness in humans. The aim of this review is to highlight the current state of stem cell therapy in the treatment of gliomas, exploring the different mechanistic approaches, clinical applicability, and the existing limitations.

Background and Objectives: Many patients with relapsed metastatic breast cancer are pre-treated with taxanes and anthracyclines, which are usually given in the neoadjuvant/adjuvant setting or as first-line treatment for metastatic disease. The primary objective of this study was to determine the overall response rate for combination treatment with gemcitabine and cisplatin in patients with locally advanced or metastatic breast cancer who had relapsed after receiving one adjuvant/neoadjuvant or first-line metastatic chemotherapy regimen containing an anthracycline with/without a taxane. Secondary endpoints included duration of response, time to progression, one-year survival probability, and toxicity., Design and Setting: A single-arm, open-label, phase 2 study conducted at 17 investigative sites in Egypt., Patients and Methods: treatment consisted of gemcitabine (1250 mg/m2) on Days 1 and 8 and cisplatin (70 mg/m2) on Day 1 of each 21-day cycle. Treatment continued until disease progression or a maximum of 6 cycles., Results: Of 144 patients all were evaluable for safety and 132 patients were evaluable for efficacy. The overall response rate was 33.3% and 45.5% of the patients with stable disease as their best response. The median time-to-progression was 5.1 months and the one-year survival probability was 73%. The most common grade 3/4 adverse events were nausea/vomiting (20.1%), neutropenia (19.4%), anemia (13.9%), asthenia (11.1%), diarrhea (9.7%), stomatitis (7.6%), leucopenia (7.6%), and thrombocytopenia (6.2%). twelve (8.3%) patients had serious adverse events., Conclusions: The results of this study indicate that gemcitabine and cisplatin were active and generally well tolerated in pretreated patients with locally advanced or metastatic breast cancer.

Objective: To compare the efficacy, safety, and outcome of thoracoscopic talc poudrage (TTP) versus povidone-iodine pleurodesis (PIP) through a thoracostomy tube as a palliative treatment of pleural effusion due to metastatic breast carcinoma (MBC)., Methods: A total of 42 MBC patients were prospectively enrolled in a randomized controlled trial. Twenty-two patients received TTP (group A), whereas 20 patients (group B) underwent pleurodesis by instilling povidone-iodine through a thoracostomy tube, as a bedside procedure., Results: The mean age was 48.2 ± 9.9 (range: 29-64) years and 50.2 ± 7 (range: 32-62) years for groups A and B, respectively (p=ns). At presentation, all patients had moderate to severe dyspnea, New York Heart Association (NYHA)>II and Medical Research Council (MRC) dyspnea scale 3-5. Morbidity in both groups was low. Post-procedure analgesic requirements due to severe pleuritic chest pain were higher in group A (18% vs 0%, p=0.2). Four patients in group A (18%) and one in group B (5%) were febrile (>38°C) within 48 h of the procedure. Both groups achieved good symptom control, with improvement in MRC dyspnea scale (1-3). There were no in-hospital deaths. Post-procedure hospital stay was lower in group B (p=0.009). The mean progression-free interval was 6.6 (range 3-15) months. At follow-up (mean: 22.6 (range: 8-48) months), recurrence of significant pleural effusion requiring intervention was noted in two and three patients in group A and group B, respectively (p=ns)., Conclusion: Povidone-iodine can be considered as a good alternative to TTP to ensure effective pleurodesis for patients with malignant pleural effusion due to MBC. The drug is available, cost effective and safe, can be given through a thoracostomy tube and can be repeated if necessary., (Copyright © 2010 European Association for Cardio-Thoracic Surgery.

Background: This prospective observational study estimated the effect of prognostic factors, particularly continued smoking during therapy, on survival in advanced non-small cell lung cancer (NSCLC) patients receiving gemcitabine-platinum. Further, prognostic factors were used to build a survival model to improve prognosis prediction in naturalistic clinical settings., Methods: Eligibility criteria included: Stage IIIB/IV NSCLC, no prior chemotherapy, and Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1. A Cox regression model was constructed and validated by randomizing patients into two datasets (Construction [C]:Validation [V]; 3:1 ratio). Country, disease stage, hypercalcemia, "N" factor, weight reduction, performance status, and superior vena cava obstruction were pre-defined variables forced into the model. Continued smoking was tested with adjustment for these variables., Results: One thousand two hundred and fourteen patients (C=891 and V=323) were enrolled. The final predictive model, established in the Construction dataset, identified four significant (p≤0.05) and independent predictors of survival, which were disease stage, performance status, gemcitabine-platinum regimen, and T-stage. Smoking during therapy was not significantly associated with survival (Hazard Ratio [95% CI]: 0.955 [0.572, 1.596], p=0.8618; versus never smokers)., Conclusions: Although continued smoking during therapy was not significantly associated with shorter survival, the model developed in this study forms an evidence-based approach to assessing prognosis in advanced stage NSCLC.

Background and Objectives: There is an unmet need for new combination treatments, especially for aggressive, visceral, and high tumor burden metastatic breast cancer. Gemcitabine (GEM) has shown synergy with vinorelbine (VRL) in preclinical models, and has a toxicity profile that is different from VRL, another recently approved cytotoxic drug that seems to be effective in the treatment of breast cancer., Methods: We studied the efficacy and side effects of the GEM-VRL combination as first-line chemotherapy in patients in an open-label, single arm, phase II study in patients with locally advanced or metastatic breast cancer who had been previously treated with an anthracycline-based regimen in the adjuvant/neoadjuvant setting., Results: Of the 74 patients enrolled, 72 patients were evaluable for the primary treatment outcome (tumor response rates). Four patients (6%) had a complete response and 26 patients (36%) had a partial response. Nineteen patients (26%) had stable disease. The median time to disease progression was 37 weeks (range, 1-60 weeks). Median duration of response was 43 weeks (range, 8.6 to 55 weeks) and one-year survival was 77% (95% confidence interval, 64% to 86%). Grade 3-4 neutropenia without fever was reported in 10% of patients, thrombocytopenia in 1%, and febrile neutropenia in 11%. The most common clinical grade 3-4 toxicities were nausea (24%) and diarrhea and stomatitis (11% each). Hospitalizations for adverse events mainly due to anemia, febrile neutropenia, septic shock and hepatic failure occurred in 7%., Conclusion: With an overall response rate of 42%, the GEM-VRL combination had promising efficacy and good tolerability in metastatic breast cancer patients.
