We study a multiorbital model for the alkaline iron selenides K(1-x)Fe(2-y)Se(2) using a slave-spin method. With or without ordered vacancies, we identify a metal-to-Mott-insulator transition at the commensurate filling of six 3d electrons per iron ion. For Hund's couplings beyond a threshold value, this occurs via an intermediate orbital-selective Mott phase, in which the 3d xy orbital is Mott...

Infrared Functional Imaging was used in microsurgery and cardio-surgery operation to assess correct blood re-perfusion after de-clamping of anastomoses. Reimplantation of arm, local sympathectomy and coronary bypass were considered. Moreover, IRFI was used to follow up the restoration of the neurovascular functions thanks to the study of the changes in the thermoregulatory capabilities of the t...

Our subject is a 36-year-old man who presented to the emergency department with bilateral lower extremity amputation at the level of the distal third of the tibia after a car accident. Surgery was planned for below-knee amputation of the right lower extremity and replantation of the left foot. The arteries dissected from the iatrogenically amputated segment were used as grafts to repair vascula...

Thoracic outlet syndrome (TOS) is a constellation of signs and symptoms caused by compression of the neurovascular structures in the thoracic outlet. TOS may be classified as either neurogenic TOS (NTOS) or vascular TOS: venous TOS (VTOS) or arterial TOS (ATOS), depending on the specific structure being affected. The basis for the surgical treatment of TOS is resection of the first rib, and it ...

BACKGROUND AND PURPOSE High-resolution 3D MR cisternography techniques such as 3D T2WI-driven equilibrium radiofrequency reset pulse (DRIVE) are used preoperatively to assess neurovascular anatomy in patients with neurovascular compression syndrome, but contrast between vessels and cranial nerves at the point of neurovascular contact is limited. The postprocessing technique subtraction of 3D T2...

An increasing number of patients with hip fracture have been seen with osteoporosis associated with osteoarthritis. Although knee dislocation is related to high-energy trauma, low-grade injuries can also lead to knee dislocation which is defined as "ultra-low velocity dislocation." The case reported here is of an 82-year-old patient who presented with a left intertrochanteric hip fracture. Part...

Unstable pelvic ring injuries require definite operative fixation. While the posterior ring can be fixed utilizing open approaches, percutaneous screw fixation has become the treatment of choice avoiding the complications of open approaches. As the pelvis is a complex three-dimensional (3D) shape with many neurovascular structures situated within it, a thorough knowledge and understanding of th...
