INTRODUCTION Horseshoe Kidneys are the most common renal fusion anomaly. When surgery is contemplated for renal-cell carcinoma in such kidneys, aberrant vasculature and isthmusectomy are the major issues to consider. We describe a case of a pure laparoscopic radical heminephrectomy with hand-sewn management of the isthmus for a 11 cm tumour in a horseshoe kidney. PRESENTATION A 47-year-old ma...

We derive some statistical properties for equilibrium states of partially hyperbolic horseshoes. We define a projection map associated to the horseshoe and prove a spectral gap for its transfer operator acting on the space of Hölder continuous observables. From this we deduce an exponential decay of correlations and a central limit theorem. We finally extend these results to the horseshoe.

Let f : π → π be a homeomorphism of the plane π. We define open sets P , called pruning fronts after the work of Cvitanović [C], for which it is possible to construct an isotopy H : π × [0, 1] → π with open support contained in ⋃ n∈Z f(P ) such that H(·, 0) = f(·) and H(·, 1) = fP (·), where fP is a homeomorphism under which every point of P is wandering. Applying this construction with f being...

We have computed all the orbit-forcing implications, up to period 8, in horseshoe-type flows or maps that generate strange attractors. The results are presented in a horseshoe implication diagram. We describe how this diagram was computed, and show how it can be used to construct a minimal (basis) set of periodic orbits which force the existence of all the periodic orbits associated with a stra...

placenta increta, a rare complication of pregnancy, is associated with significant postpartum hemorrhage often requiring emergency hysterectomy. we report a case of conservative management, with a combination of parenteral methotrexate, serial ultrasound and β-hcg assessment. serum β-hcg levels were undetectable after 8 weeks of therapy. a scan at 6 months showed complete involution of the uter...

introduction: the use of cell phones is widespread and there are public concerns regarding its possible deleterious effects on human health especially on the pregnancy outcomes. in this study, structural changes of the placenta after applying the cell phone radiation were examined in the mice model.   materials and methods: for this work, 40 pregnant balb/c mice were randomly allocated to one c...
