The c linica l significance of infundibular widening (junctional dilatation) of the origin of an intracranial artery has been a topic of debate; junc tional dilatation is considered preaneurysmal by some investigators and a normal variant by others. Aneurysm form ation or hemorrhage from an infundibulum rarely has been reported. A pati ent is reported in whom both aneu rysm development at the i...

Many complications have been reported during or after anterior cruciate ligament (ACL) reconstruction, including infection, bleeding, tibial tunnel widening, arthrofibrosis, and graft failure. However, arterial injury has been rarely reported. This paper reports a case of an anterior tibial arterial injury during bicortical tibial drilling in arthroscopic ACL reconstruction, associated with an ...

Examination revealed an asthenic built child with height of 162 cm, arm span 174 cm, arm span-toheight ratio 1.074 and US:LS ratio 0.82. He had high arched palate, arachnodactly, positive wrist and thumb signs. There were signs of consolidation over left base. Cardiovascular system examination revealed a short diastolic murmur in aortic space. Skiagram revealed a massive consolidation of left l...

Based on constraint database techniques, we present a new approach to software verification. This new approach has some similarity to abstract interpretation that uses various widening operators; therefore, we call the new approach l-u widening. We show that our l-u widening leads to a more precise over-approximation of the invariants in a program than comparable previously proposed widening op...
