A large series of split cord malformation (SCM). Over the last 22 years, we have operated more than 1500 patients of SD, of which over 450 are (SCM), and 300 are with various lipomatus malformations. About 55% type II and 45% type I SCM. A separate sub-classification of type I SCM (a,b,c and d), is presented which alter the surgical approach and influence the results. Overall improvement following surgery in patients with SCM was observed in 94%. Fifty percent patients improved and 44% remained stable. However, deterioration was noticed in 6%, mostly with composite type of SCM. A paradigm for management of SCM is provided taking into consideration also the author’s large experience.

We have carried out a simulation of quantum chromodynamics using the hybrid-molecular-dynamics algorithm with two flavors of Kogut-Susskind quarks. We have used Kogut-Susskind and Wilson valence quarks to calculate the hadron mass spectrum. Among our extensive results we discuss baryon hyperfine splitting, the nucleon-to-p mass ratio, the scalar-to-tensor-glueball mass ratio, and the quantization and susceptibility of the topological charge. We have used a gauge coupling of 6/g 2 = 5.60, and quark masses am q =0.025 and 0.01, in generating gauge configurations on 12 4 , 12 3 x24, and 16 4 lattices.
