Insights into Anton Syndrome: When the brain denies blindness.

INTRODUCTION: Anosognosia, a neurological condition, involves a lack of awareness of one's neurological or psychiatric deficits. Anton Syndrome (AS), an unusual form of anosognosia, manifests as bilateral vision loss coupled with denial of blindness. This systematic review delves into 64 studies encompassing 72 AS cases to explore demographics, clinical presentations, treatments, and outcomes. MATERIALS AND METHODS: The study rigorously followed PRISMA guidelines, screening PubMed, Google Scholar, and Scopus databases without timeframe limitations. Only English human studies providing full text were included. Data underwent thorough assessment, examining patient demographics, etiological variables, and treatment modalities. RESULTS: Sixty-four studies met the stringent inclusion criteria. Examining 72 AS cases showed a median age of 55 (6 to 96 years) with no gender preference. Hypertension (34.7 %) and visual anosognosia (90.3 %) were prevalent. Stroke (40.3 %) topped causes. Management included supportive (30.6 %) and causal approaches (30.6 %). Improvement was seen in 45.8 %, unchanged in 22.2 %, and deterioration in 11.1 %. Anticoagulation correlated with higher mortality (p < 0.05). DISCUSSION: AS, an unusual manifestation of blindness, stems mainly from occipital lobe damage, often due to cerebrovascular incidents. The syndrome shares features with Dide-Botcazo syndrome and dates back to Roman times. Its causes range from strokes to rare conditions like multiple sclerosis exacerbation. Accurate diagnosis involves considering clinical presentations and imaging studies, distinguishing AS from similar conditions. CONCLUSION: This comprehensive review sheds light on AS's complex landscape, emphasizing diverse etiologies, clinical features, and treatment options. Tailored treatments aligned with individual causes are crucial. The study's findings caution against blanket anticoagulation therapy, suggesting a nuanced approach. Further research is pivotal to refine diagnostics and optimize care for AS individuals.

Is simultaneous occurrence of meningioma and glioblastoma a mere coincidence?

BACKGROUND: It is extremely unusual for multiple tumors to arise from different cell types and occur at the same time inside the brain. It is still unknown whether or not the coexistence of meningioma and glioblastoma is connected in any way or if their simultaneous appearance is merely a coincidence. OBJECTIVE: We conduct a comprehensive literature review on cases of concurrent meningioma and glioblastoma occurrence to elucidate the underlying concepts that may constitute this coexistence. METHODS: We searched for articles on the topic of glioblastoma coexisting with meningioma in Google Scholar, PubMed, and Scopus. First, the initial literature searches were conducted for study selection and the data collection processes. After evaluating the title and abstract, the papers were selected. RESULTS: We analyzed 21 studies describing 23 patients who had both glioblastoma and meningioma. There were ten male patients (47.6 %) and thirteen female patients (61.9 %). The mean age of patients at diagnosis was 61 years old (the range 30 to 86). In 17 cases, both tumors were in the same hemisphere (80.9 %). In 5 cases, they were in the other hemisphere (23.8 %), and in one case, the glioblastoma was in the left hemisphere and the olfactory meningioma was In 5 cases, they were in the other hemisphere (23.8 %), and in one case, the glioblastoma was in the left hemisphere and the olfactory meningioma was in the anterior cranial fossa. In 61.9 % of cases, headache was the predominant symptom. CONCLUSION: Understanding the unique challenges posed by the coexistence of glioblastoma and meningioma is crucial for developing effective treatment strategies. Further investigation into the underlying molecular mechanisms and genetic factors involved in this rare occurrence could pave the way for personalized therapies tailored to each patient's specific needs.

Non-colloid-cyst primary brain tumors: A systematic review of unexpected fatality.

OBJECTIVE: Primary brain tumors have the potential to present a substantial health hazard, ultimately resulting in unforeseen fatalities. Despite the enhanced comprehension of many diseases, the precise prediction of disease progression continues to pose a significant challenge. The objective of this study is to investigate cases of unexpected mortality resulting from primary brain tumors and analyze the variables that contribute to such occurrences. METHODS: This systematic review explores research on individuals diagnosed with primary brain tumors who experienced unexpected deaths. It uses PRISMA standards and searches PubMed, Google Scholar, and Scopus. Variables considered include age, gender, symptoms, tumor type, WHO grade, postmortem findings, time of death - time taken from first medical presentation or hospital admission to death, comorbidity, and risk factors. RESULTS: This study examined 46 studies to analyze patient-level data from 76 individuals with unexpected deaths attributed to intracranial lesions, deliberately excluding colloid cysts. The cohort's age distribution showed an average age of 37 years, with no significant gender preference. Headache was the most common initial symptom. Astrocytomas, meningiomas, and glioblastoma were the most common lesions, while the frontal lobe, temporal lobe, and cerebellum were common locations. Meningiomas and astrocytomas showed faster deaths within the first hour of hospital admission. CONCLUSION: The etiology of unforeseen fatalities resulting from cerebral tumors elucidates an intricate and varied phenomenon. Although unexpected deaths account for a very tiny proportion of total fatalities, it is probable that their actual occurrence is underestimated as a result of underreporting and misdiagnosis.

Osteoporosis and vitamin D consumption: knowledge and practice in different Arab countries.

Despite the high prevalence of osteoporosis and vitamin D deficiency, the knowledge about osteoporosis and vitamin D-related practices were moderate in some countries in the Middle East and North Africa (MENA) region. Improving knowledge through awareness campaign and screening programs is essential to enhance vitamin D-related practices. PURPOSE: Osteoporosis is the most common skeletal disease, which usually remains silent until fractures occur. Vitamin D deficiency impairs bone mineralization and increases the risk of osteoporosis. Despite being relatively sunny, the Middle East and North Africa (MENA) region has a high prevalence of osteoporosis and hypovitaminosis D. This study aims to assess the knowledge about osteoporosis and vitamin D-related practices and to determine the correlation between them in some countries of the MENA region. METHODS: A cross-sectional study was performed in Lebanon, Syria, Egypt, Palestine, Iraq, Jordan, and Saudi Arabia. From each country, 600 participants were enrolled. The survey included four sections: sociodemographic information, past medical history, Osteoporosis Knowledge Assessment Tool to assess the knowledge about osteoporosis, and Practice Towards Vitamin D scale to assess vitamin D-related practices. RESULTS: Our study found that 67.14% of respondents had moderate knowledge about osteoporosis and 42.31% had moderate vitamin D-related practices. Higher knowledge level was reported in the young, females, Syrians, singles, postgraduates, and healthcare employees (p < 0.05). Better vitamin D-related practices were detected in the elderly, males, Egyptians, married, and high school or below educational level (p < 0.05). The Internet was the most listed source of information. Adequate osteoporosis knowledge was associated with better vitamin D-related practices (p < 0.001). CONCLUSION: Most participants, representing some countries of the MENA region, displayed moderate knowledge regarding osteoporosis and moderate vitamin D-related practices. Adequate knowledge about osteoporosis is essential to improve practices, so awareness campaigns and screening programs should be more frequently implemented.
