Endoscopic Treatment of Neurosurgical Pathologies: Experience and Future Prospects in the Neurosurgery Department at Mohammed 6 University Hospital, Marrakech

Endoscopy is a new procedure in neurosurgery that uses optical magnification and video-assisted endoscopes to guide the hand to hard-to-reach locations. Despite extensive trials and meta-analyses, no definitive results have been published on its benefits. Neuroendoscopy has expanded beyond ventricular operations to treat various neurosurgical conditions, including cyst fenestration, tumor biopsy, tumor excision, and metastatic disease evaluation. It is beneficial for patients with hydrocephalus, intraventricular cysts, and concurrent hydrocephalus. Intracranial cysts are ideal for neuro-endoscopic therapy, and it can treat cystic craniopharyngiomas, dysontogenic tumors, gliomas, and metastases. Endoscopic tumor biopsy is a reliable technique for ventricle brain tumors. our study treated 480 hydrocephalus patients using endoscopic third ventriculostomy, accounting for 50.5% of cases. The most common cause was Sylvius aqueduct stenosis. Endoscopy was beneficial for treating colloidal cysts, arachnoid cysts, pituitary adenoma, and craniopharyngioma. It also served as a complement to microsurgery in 55 cases. Neuroendoscopy improved sciatic pain in 15 patients who underwent lumbar discectomy, with only minor issues due to the surgical scar. Neuroendoscopic surgery is expected to advance significantly in the future, with advancements in camera and optical technology, surgical instrument design, navigation systems, multiport surgery, and improved microsurgery.

A Study on the Indoor Heating Effect of Blue Green Roofs during Cold Waves

With the increasing frequency of heat-based climate disasters due to recent climate change, various technologies are being developed to mitigate their impacts. Blue-green roofs (BGR) is a technology that consists of rainwater storage tanks and grass layers installed on building rooftops to reduce the infiltration of cold or heat into the building interiors. This study analyzed the indoor temperature changes between two buildings with equal rooftop area, one equipped with a BGR and the other without, during winter season to evaluate their heating effects. The results indicated an average heating effect of 0.56 °C across the entire monitoring period for the building with a BGR. The heating effect was observed only at temperature ranges below 6.5 °C, with no effect at higher temperatures. This study suggests that even installing a roof-based system can provide some degree of heating benefits. Further research and development are needed to improve the heating efficien through additional technological advancements.

A comprehensive outline towards conciliation in the contemporary world of E-commerce

Since the start of the millennial era, technical advancements have led to exponential growth in electronic commerce, or e-commerce. According to the United Nations Conference on Trade and Development (UNCTAD), e-commerce sales reached about US$25 trillion globally in 2021 [1] and are expected to grow at a compound annual growth rate of 9% through 2027, which is twice as fast as the 4% annual growth rate predicted for traditional in-person retail [2]. Online dispute resolution (ODR) techniques that aim to settle disagreements and lower the likelihood of expensive lawsuits are becoming more and more necessary as both individuals and corporations use online shopping platforms. Due of its legally binding nature, arbitration is the most formal method, as was briefly discussed [3]. Online arbitration is carried out using electronic methods, like email and digital tools designed to make the duties of arbitrators and parties to a dispute easier. It adheres to the same rules and processes as traditional arbitration. On the plus side of e-arbitration, advancements in technology allow for time and cost savings without sacrificing the ease of remote filing. The conclusion of e-arbitration agreements raises several negative issues, including privacy and data protection issues for the consumer signing the agreements and power imbalances between corporate entities and the consumer. The degree to which artificial intelligence (AI) is effectively and sufficiently analysing a dispute between parties is up for debate because it's unclear how new this adjudication process is.
