A general survey is provided on the capability of Monte Carlo (MC) modeling in tissue optics while paying special attention to the recent progress in the development of methods for speeding up MC simulations. The principles of MC modeling for the simulation of light transport in tissues, which includes the general procedure of tracking an individual photon packet, common light-tissue interactio...

Unicentric Castleman's disease (UCD) is a rare disorder of unknown etiology characterized by localized lymphoid tissue proliferation and interfollicular hypervascularity. A 33-year-old Caucasian female presented with vague abdominal discomfort and pain with pressure. Ultrasound and computed tomography detected a large peripancreatic mass. Robotic-assisted resection of the mass along with en blo...

Piezoelectric surgery is a novel surgical approach used in orthodontic treatment for rapid tooth movement. This paper presents a case series wherein osseous outgrowths were observed in response to piezosurgery-assisted en-masse retraction. Sixteen patients requiring upper premolar extractions were treated with miniscrew-supported en-masse retraction and received minimally invasive decortication...

Despite the remarkable developments in neurosurgical and neuro-interventional procedures, the optimal treatment for large or giant partially thrombosed aneurysms with a mass effect remains controversial. The authors report a case of a partially thrombosed aneurysm with a mass effect, which was successfully treated by stent-assisted coil embolization. A 41-year-old man presented with headache. B...

-This study demonstrated techniques for visualization of detailed brain anatomy with two dimensional ultrasound. The use of large aperture focused ultrasound transceivers appears to be essential for displaying the outlines of thalamus, internal capsule and substantial nigra in addition to those of the ventricles. The ability to vary grey scale and edge enhancement using either linear or logarit...

This contribution introduces a computer- and robot-assisted framework for stereotactic neurosurgery on small animals. Two major elements of this framework are presented in detail: a robotic stereotactic assistant and the software framework for placement of probes into the brain. The latter integrates modules for registration, insertion control, and preoperative path planning. Two options for pa...

A 59-year-old woman with a history of von Recklinghausen's disease (VRD) suffered sudden chest pain. Enhanced chest computed tomography showed massive hemothorax, but no evidence of tumors or an obvious bleeding point in the thorax. After we had ensured a stable hemodynamic condition, we performed video-assisted thoracic surgery to remove the hematoma. The bleeding point was in a branch of the ...

PURPOSE To report two cases of femtosecond laser-assisted small incision deep lamellar endothelial keratoplasty (DLEK) for patients with corneal endothelial decompensation by Fuchs dystrophy and glaucoma METHODS Femtosecond laser (IntraLase; IntraLase Corp., Irvine, CA) with 15 kHz of repetition rate, was used for a 9.5 mm diameter by 400 micrometer thickness donor corneal lamellar dissection...

Introduction: Ovarian serous carcinoma is an aggressive malignancy, often with metastases at presentation. Cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy has been studied as a treatment option for intraperitoneal spread of ovarian cancer. Hyperthermic intrathoracic chemotherapy, the thoracic counterpart to hyperthermic intraperitoneal chemotherapy, is emerging as ...

This paper present a new developed technique for robotic surgical model with high flexibility used in Total Knee Replacement (TKR) surgery. The proposed model used robot arm assisted technique to play the role of computer assisted surgery (CAS). Most famous type’s orthopedic surgery equipments used navigation system. The system provide surgeon with extra support, as it help optimizing the impla...
