Pollutants and parasites represent stressors for fish at the individual, population, or community levels. The current study outlines the seasonal infestation pattern of Oreochromis niloticus by protozoan and helminths parasites linked to some physicochemical parameters (pH, dissolved oxygen, total dissolved solids, and electrical conductivity), and metals (Cd, Pb, Fe, Zn, and Ca), at nine selected sites in River Nile (Greater Cairo area) from summer 2019 till spring 2020. Most of the studied criteria in Nile water samples showed normal levels during all seasons compared to the recommended limits of EPA.

Article Synopsis
  • The study evaluates the effects of the Lake Manzala development, initiated in 2017, on factors like water quality and biomarkers in fish (Oreochromis niloticus) and snails (Biomphalaria alexandrina) sampled in 2021, comparing them to results from 2015.
  • Results showed improved water quality, with increased electrical conductivity, reduced heavy metal contamination (Pb, Cd, Cu, Zn), and better overall health indicators in fish and snails, indicating a biologically improved environment.
  • Histopathological assessments revealed better tissue conditions in fish and snails from Port Said compared to Dakahlia, while immune responses indicated more inflammation in Dakahlia, suggesting

Background: Postoperative cerebrospinal fluid (CSF) leak is a major concern after posterior fossa surgery with significant clinical implications. It has been postulated that replacing the bone flap, performing a craniotomy, would reinforce the surgical closure and decrease rates of CSF leak. This systematic review and meta-analysis compared the rate of CSF leak after posterior fossa craniotomies versus craniectomies.
