Misleading Mercedes-Benz sign: A case report of misdiagnosed cholecysto-hydatid cyst fistula in acute cholecystitis.

Introduction: Liver hydatid cysts represent a significant health concern globally, particularly in endemic regions like Tunisia. While they often lead to complications such as biliary fistulas, diagnostic errors can arise from radiologic signs like the "Mercedes Benz sign," which indicates gas within the gallbladder. This report highlights the challenge of diagnosing a rare cholecysto-hydatid cyst fistula, where the presence of gas in the gallstones initially suggested a fistula.

Effects of high-intensity interval training and plyometric exercise on the physical fitness of junior male handball players.

Objective: This study analyzed the effects of high intensity interval training (HIIT) combined with plyometric exercise on the physical fitness of junior male handball players.

Patients And Methods: Subjects (age ~17 years) were randomly divided between experimental (n=17) and control (n=15) groups. During the 8-week intervention, the experimental group replaced a part of their regular regimen by HIIT, combined with plyometric exercise.

Effects of flexibility combined with plyometric exercises vs isolated plyometric or flexibility mode in adolescent male hurdlers.

Background: This study aims to determine the effect of flexibility exercises combined with plyometrics in hurdles race, on physical fitness, motor skills (MS) and hip range of motion.

Methods: Thirty-four male hurdlers, (age=15.7±0.

[The indoor sport: is it a risk factor for allergic rhinitis?].

Introduction: The high prevalence of allergic rhinitis that occurs in elite athletes has been extensively investigated. However, data among recreational athletes practicing indoor activities remain contradictory. The aim of the present study was to determine whether taking part in gym based sporting activities constitutes a risk factor for allergic rhinitis in recreational athletes.

Radiation effect on viscous flow of a nanofluid and heat transfer over a nonlinearly stretching sheet.

In this work, we study the flow and heat transfer characteristics of a viscous nanofluid over a nonlinearly stretching sheet in the presence of thermal radiation, included in the energy equation, and variable wall temperature. A similarity transformation was used to transform the governing partial differential equations to a system of nonlinear ordinary differential equations. An efficient numerical shooting technique with a fourth-order Runge-Kutta scheme was used to obtain the solution of the boundary value problem.
