We describe a case of an unusual finding during robotic-assisted laparoscopic radical prostatectomy and bilateral pelvic lymphadenectomy in a 66-year-old male with Stage IIb (T2c, N0, M0) prostate adenocarcinoma. During the operation, intraperitoneal examination of the rectovesical pouch revealed calcifications and stones which were subsequently identified as gallstones. While these stones were not noted initially on this patient's preoperative multiparametric MRI (mpMRI), a retrospective review demonstrated hypointense foci in the rectovesical pouch...

For children with autism spectrum disorders (ASDs), social robots are increasingly utilized as therapeutic tools in order to enhance social skills and communication. Robots have been shown to generate a number of social and behavioral benefits in children with ASD including heightened engagement, increased attention, and decreased social anxiety. Although social robots appear to be effective social reinforcement tools in assistive therapies, the perceptual mechanism underlying these benefits remains unknown...

BACKGROUND: To limit the potential short and long-term morbidity of lymphadenectomy, sentinel lymph node (SLN) biopsy has been proposed for endometrial cancer. The principle of SLN biopsy relies on removal of a small number of lymph nodes that are the first drainage basins from a tumor and thus the most likely to harbor tumor cells. While the procedure may reduce morbidity, efficacy data is limited and little is known about how commonly the procedure is performed. OBJECTIVE: We examined the patterns and predictors of use of SLN biopsy and outcomes of the procedure in women with endometrial cancer who underwent hysterectomy...

Leiomyosarcoma is a rare and aggressive retroperitoneal tumor arising from the smooth muscle of the tunica media. The IVC accounts for > 70% of all leiomyosarcomas, with the renal vein being limited to few case reports (1)(2)(3)(4)(5). Accurate pre-operative diagnosis is rare as the origin is unclear and its involvement of the vessels makes biopsy prohibitively dangerous (6). Treatment involves radical nephrectomy followed by adjuvant radiation and/or chemotherapy, with poor prognosis (7)(8). Herein, we describe the laproscopic dissection of a retroperitoneal renal vein tumor using a robotic approach...

Piezoelements used in robotics require large elasticity and extensibility to be installed in an artificial robot skin. However, the piezoelements used until recently are vulnerable to large forces because of the thin solid materials employed. To resolve this issue, we utilized a natural rubber and applied our proposed new method of aiding with magnetic and electric fields as well as filling with magnetic compound fluid (MCF) and doping. We have verified the piezoproperties of the resulting MCF rubber. The effect of the created magnetic clusters is featured in a new two types of multilayered structures of the piezoelement...

Acquisition of stabilized video is an important issue for various type of digital cameras. This paper presents an adaptive camera path estimation method using robust feature detection to remove shaky artifacts in a video. The proposed algorithm consists of three steps: (i) robust feature detection using particle keypoints between adjacent frames; (ii) camera path estimation and smoothing; and (iii) rendering to reconstruct a stabilized video. As a result, the proposed algorithm can estimate the optimal homography by redefining important feature points in the flat region using particle keypoints...

The robotic approach to cardiac surgery offers patients numerous potential advantages compared with a traditional sternotomy approach including shorter hospital length of stay, reduced pain, fewer blood transfusions, and a quicker return to normal daily activities. At the same time, robotic cardiac surgery requires that the anesthesiologist employs several subspecialty skillsets in order to provide optimal care for these patients. Multiple different regional anesthesia techniques may be used to improve analgesia, reduce opioid dosages, and facilitate rapid extubation at the conclusion of the case...

Robotic surgery is a conceptual fusion of the conventional open surgery and the minimally invasive laparoscopic surgery. We reviewed the current role of robotic-assisted laparoscopy in the field of reproductive surgery by a literature search in PubMed database. We analyzed the reported advantages and limitations of the use of robotics in reproductive surgeries like myomectomy, tubal reanastomosis, endometriosis, ovarian tissue cryopreservation, and ovarian transposition. Overall, robotic assistance in reproductive surgery resulted in decreased blood loss, less post-operative pain, shorter hospital stay, and faster convalescence, whereas reproductive outcomes were similar to open/laparoscopic approaches...
