Acute scrotum as a complication of Thiersch operation for rectal prolapse in a child

BACKGROUND: We report a case of acute scrotal condition that presented in a four year old male child one year after being treated for an idiopathic rectal prolapse utilizing Thiersch wire. CASE PRESENTATION: The acute scrotum had resulted from spreading perianal infection due to erosion of the circlage wire. The condition was treated with antibiotics and removal of the wire. The child made an uneventful recovery. CONCLUSION: This case highlights that patients with Thiersch wire should be followed until the wire is removed. Awareness of anal lesions as a cause of acute scrotal conditions, and history and physical examination are emphasized

Reliable analysis for the nonlinear fractional calculus model of the semilunar heart valve vibrations

WOS: 000285931900002The aim of this paper is to solve the equation of motion of semilunar heart valve vibrations using the homotopy perturbation method. The vibrations of the closed semilunar valves were modeled with fractional derivatives. The fractional derivatives are described in the Caputo sense. The methods give an analytic solution in the form of a convergent series with easily computable components, requiring no linearization or small perturbation. Analytical solution is obtained for the equation of motion in terms of Mittag-Leffler function with the help of Laplace transformation. These solutions can be interesting for a better fit of experimental data. Copyright (C) 2010 John Wiley & Sons, Ltd
