The functional survival of the same silicone double lumen catheter (DLC) was analyzed in relation with the mode of its insertion. Thirty-seven catheters were surgically inserted (34 in the right internal Jugular vein, 3 in the left internal Jugular vein), while 28 were percutaneously inserted (25 in the right internal Jugular vein, 3 in the left internal Jugular vein). The functional survival was calculated using Kaplan Meier method. Significant survival difference was looked for with log rank test. The maximum follow-up time was 62 months for surgically inserted DLC and 12 months for their percutaneous counterpart. There was no significant functional survival difference between the two groups at one year. At this term 86% of DLC were still in use. We conclude from our experience that the mode of insertion does not significantly modify the success rate of this type of blood access. The simplest and lightest method (i.e. percutaneous) should therefore be preferred.

Background: Aortoiliac disease (AID) is a variant of peripheral artery disease involving the infrarenal aorta and iliac arteries. Similar to other arterial diseases, aortoiliac disease obstructs blood flow through narrowed lumens or by embolization of plaques. AID, when symptomatic, may present with a triad of claudication, impotence, and absence of femoral pulses, a triad also referred as Leriche Syndrome (LS).

Introduction: Arteriovenous (AV) fistula creation is the most common surgical procedure for providing vascular access for haemodialysis in patients with chronic kidney disease (CKD). The functioning of fistula dictates the quality of dialysis and the longevity of patients. The most common circumstances that require surgical takedown of AV fistula are thrombosis and rupture.

Introduction: The present study aimed to explore the epidemiologic threats and factors associated with the coronavirus disease 2019 (COVID-19)-associated mucormycosis (CAM) epidemic that emerged in Egypt during the second COVID-19 wave. The study also aimed to explore the diagnostic features and the role of surgical interventions of CAM on the outcome of the disease in a central referral hospital.
Methodology: The study included 64 CAM patients from a referral hospital for CAM and a similar number of matched controls from COVID-19 patients who did not develop CAM.

Introduction: Since the dawn of the new millennium, Candida species have been increasingly implicated as a cause of both healthcare-associated as well as opportunistic yeast infections, due to the widespread use of indwelling medical devices, total parenteral nutrition, systemic corticosteroids, cytotoxic chemotherapy, and broad-spectrum antibiotics. Candida tropicalis is a pathogenic Candida species associated with considerable morbidity, mortality, and drug resistance issues on a global scale.
Methodology: We report a case of a 43-year-old man who was admitted to our hospital for further management of severe coronavirus disease 2019 (COVID-19) pneumonia.
