Gliomas are the most common primary tumors of the nervous system, accounting for approximately 81% of brain tumors. The primary treatment for these primary brain tumors, especially those of high grade, is surgical resection with subsequent therapy such as targeted radiotherapy, chemotherapy, or supportive care. In an effort to devise nuanced ways to treat gliomas, studies have examined various chemical agents to expand therapeutic avenues for gliomas. In this study, we investigate the applications of ethylenediaminetetraacetic acid (EDTA) in the investigation and treatment of gliomas. Searches were conducted on PubMed to find studies about the use of EDTA in the treatment of glioma. We identified 36 studies that had the information needed for analysis. We collected information on the dosage of EDTA, the agent that EDTA was complexed with, the route of administration, the outcome of the EDTA usage, and the type of glioma cells that were involved. In addition, a one-way analysis of variance was performed to identify any relationships between the effect of cell type, study purpose, and year published on dosage. We identified 36 articles that met our inclusion criteria. In-vitro studies utilized EDTA in various complexes to evaluate cellular viability, including proliferation and toxicity, intracellular enzyme kinetics, and intercellular interactions such as chelation and cellular aggregation. In-vivo studies predominantly utilized the versatile nature of EDTA as a tracer for imaging studies involved in diagnostics and identifying recurrent tumor growth and localization in human patients. Our statistical analysis failed to identify any significant relationships between cell type, study purpose, and publication year on EDTA dosage. We identified a variety of uses for EDTA in the investigation hopefully providing physicians with information regarding the context and applications of EDTA to assist in exploring new treatment options for glioma patients.

Wernicke's encephalopathy (WE) is a neuropsychiatric condition caused by thiamine deficiency often associated with alcoholism. Other less common causes include prolonged gastroenterology problems or dietary insufficiencies associated with hyperemesis gravidarum, bariatric surgery, and eating disorders. Prolonged WE without proper treatment can lead to the chronic and irreversible condition, Wernicke-Korsakoff syndrome. Despite being known for its classic triad of clinical symptoms (nystagmus/ophthalmoplegia, gait ataxia, and confusion), WE patients more commonly present with nonspecific symptoms of altered mental status. Obscure clinical presentations often led to delays in the appropriate of patients with WE. We are presenting a case of WE that is unusual because the underlying cause is schizophrenia and the lack of alcohol use. For a punctual diagnosis, a high index of suspicion is essential to prevent further exacerbation of neuronal death seen in WE. IV thiamine should be administered to any patient with acute encephalopathy or altered mental status, given its low cost and lack of side effects.

Diabetes-related macular edema is a fast-spreading condition that has damaged the lives of countless people throughout the globe. The current incorporation of subthreshold micropulse laser has indicated the precedence of laser therapy in the treatment of diabetic macular edema; nonetheless, vitreoretinal surgery in conjunction with anesthetics correlates with early mitigation of damage to the fovea. Surgery is a delicate procedure that necessitates careful consideration of the types and locations of anesthetics used. Depending on the individual being treated, various drugs and methods may be necessary. For example, some individuals may be allergic to conventional anesthetics, resulting in more severe consequences. In the surgical treatment of diabetic macular edema, the topical anesthetic was utilized more frequently than subconjunctival anesthesia, according to the review’s statistical analysis. The examined literature indicated that topical lidocaine was the most employed anesthetic for vitreoretinal surgery; however, alternatives to lidocaine exist, and their effects should be investigated. Consequently, we would want to highlight the impacts of each of the several surgical medications and anesthetics used to treat diabetic macular edema.
