Cystic Echinococcosis of the Liver: Correlation Between Intra-Operative Ultrasound and Pre-Operative Imaging.

Imaging plays an essential role in the management of hepatic hydatid cysts (HCE). The objective of our study was to determine the correlation between pre-operative ultrasound, computed tomography (CT), and intra-operative ultrasound (IOUS) in studying the characteristics and complications of HCE. This was a prospective, descriptive, and analytical study conducted in the General Surgery Department of Habib Bourguiba Hospital in Sfax.

Effect of shading imposed by the algae Chaeotomorpha linum loads on structure, morphology and physiology of the seagrass Cymodocea nodosa.

In shallow coastal waters, seagrass and macroalgae occur together but under eutrophic conditions, bloom-forming algae can take over seagrasses causing an irreversible regime shift. Understanding the effect of macroalgae loads on seagrass meadows at an early stage can help prevent the loss of these ecosystems and the services they provide. In the present study, in situ experiments were conducted for 90 days in Bekalta (eastern coast of Tunisia) to assess the response of the seagrass Cymodocea nodosa when challenged with shading induced by filamentous macroalgae Chaetomorpha linum.

[Predictive factors for anastomotic leakage after colon cancer surgery].

Introduction: in colon cancer surgery, anastomotic fistula (AF) is considered the most feared complication. The purpose of this study was to identify predictive factors associated with anastomotic fistula after colon cancer surgical resection and to describe the impact of this complication on mortality and postoperative length of stay.

Methods: we conducted a retrospective, descriptive and analytical study in the Department of General Surgery at the Habib Bourguiba Hospital in Sfax, Tunisia from 1 January 2013 to 31 December 2020.

A comparative study of trace elements in Cymodocea nodosa from three semi-enclosed coastal areas in Tunisia.

The present study quantifies the levels of five trace elements (TEs) Zn, Cu, Ni, Pb, and Cd in the leaves and rhizomes of Cymodocea nodosa as well as the surficial sediments from three semi-enclosed coastal areas in Tunisia, in the south Mediterranean Sea. Samples were taken from the Bizerte and Ghar El Melh lagoons and from marina Cap Monastir. The TE ranking was found to be Zn > Cu > Pb > Ni > Cd in sediments and Zn > Cu = Ni = Pb = Cd in C.
