the distally based sural fasciocutaneous flap has become a main part of the reconstruction of the lower leg, heel and foot. however, perfusion problems and venous congestion have been reported. over the past decade, several flap modifications have been reported to improve flap viability and to solve a myriad of reconstructive needs. the purpose of this paper is to describe our experience in har...

right ventricular failure due to right coronary artery disease, right ventricular hypertrophy, stunning, abnormal septal motion, myocardial infarction, or non-homogeneous distribution of cardioplegia is an uncommon but serious complication of open heart surgery. we report a patient with severe right ventricular hypertrophy secondary to severe mitral valve stenosis and another patient with detac...

The ovarian hyperstimulation syndrome (OHSS) is a consequence of superovulation therapy for assisted conception procedures. This potentiallyfatal condition is avoidable by the judicious use of gonadotropins and carefulmonitoring of stimulation regimens. Women who are at particular risk ofdeveloping the syndrome include those who have polycystic ovaries and thosewho are young (under 30 years). W...

The serial Jacobi algorithm (either one-sided or two-sided) for the computation of a singular value decomposition (SVD) of a general matrix has excellent numerical properties and parallelization potential, but it is considered to be the slowest method for computing the SVD. Even its parallelization with some parallel cyclic (static) ordering of subproblems does not lead to much improvement when...

Procedure cloning is an interprocedural optimization where the compiler creates specialized copies of procedure bodies. To clone a procedure, the compiler repli-cates it and then divides the incoming calls between the original procedure and the copy. By carefully partitioning the call sites, the compiler can ensure that each clone inherits an environment that allows for better code optimization...

INTRODUCTION In 1967 Donald Ross introduced the subcoronary Ross procedure consisting of transplantation of the autologous pulmonary valve into aortic position. We describe our 15-year experience in Ross procedures. METHODS 576 subcoronary operations have been performed (436 male and 140 female patients); the mean age was 45±11.9 years. (range, 13 to 70 years). The mean follow-up was 7±4.2 ye...
