Prognostic significance of tumor mitotic rate in T2 melanoma staged with sentinel lymphadenectomy.

Background And Objectives: Tumor mitotic rate (TMR) is an important prognostic variable for patients with thin melanoma. However it remains unclear what the significance of TMR is for more deeply invasive melanoma pathologically staged with a sentinel lymph node biopsy. We sought to determine the prognostic value of TMR in clinically node-negative T2 melanoma patients staged with sentinel lymphadenectomy.

Systematic review: surgery for patients with metastatic melanoma during active treatment with ipilimumab.

Studies of ipilimumab have shown improved overall survival in patients with metastatic cutaneous melanoma. As a result, use of ipilimumab in patients with Stage IV melanoma is rapidly increasing. Patients with Stage IV melanoma often require urgent operations for complications from metastases, but little is known about the safety of surgical intervention for patients receiving ipilimumab.

Perioperative blood transfusion is associated with decreased survival in patients undergoing pancreaticoduodenectomy for pancreatic adenocarcinoma: a multi-institutional study.

Introduction: In this multi-institutional study of patients undergoing pancreaticoduodenectomy for pancreatic adenocarcinoma, we sought to identify factors associated with perioperative transfusion requirement as well as the association between blood transfusion and perioperative and oncologic outcomes.

Methods: The surgical databases across six high-volume institutions were analyzed to identify patients who underwent pancreaticoduodenectomy for pancreatic adenocarcinoma from 2005 to 2010. For statistical analyses, patients were then stratified by transfusion volume according to whether they received 0, 1-2, or >2 units of packed red blood cells.

Routine restaging PET/CT and detection of initial recurrence in sentinel lymph node positive stage III melanoma.

Background: Follow-up of patients with sentinel lymph node-positive stage III melanoma uses history, physical exam, and cross-sectional imaging. The aim of this study was to evaluate positron emission tomographic (PET)/computed tomographic (CT) scans in the detection of recurrence.

Methods: From 2003 to 2009, a single-institution prospective database of all cutaneous melanoma patients was used to identify sentinel lymph node-positive stage III patients with disease-free survival >1 year and 1 restaging PET/CT scan.

Factors influencing readmission after pancreaticoduodenectomy: a multi-institutional study of 1302 patients.

Objective And Background: Morbidity, mortality, and length of hospital stay after pancreaticoduodenectomy (PD) have significantly decreased over recent decades. Despite this progress, early readmission rates after PD have been reported as high as 50%. Few reports have delineated factors associated with readmission after PD.

Early recurrence in sentinel lymph node positive stage III melanoma patients.

Patients with sentinel lymph node (SLN) positive melanoma have a significant recurrence risk. We sought to examine variables associated with development of early recurrence. A prospective institutional review board-approved database of cutaneous melanoma patients treated from 2003 to 2010 was used to identify SLN positive stage III patients with 1 year of follow-up.

Continuous detection and decoding of dexterous finger flexions with implantable myoelectric sensors.

A rhesus monkey was trained to perform individuated and combined finger flexions of the thumb, index, and middle finger. Nine implantable myoelectric sensors (IMES) were then surgically implanted into the finger muscles of the monkey's forearm, without any adverse effects over two years postimplantation. Using an inductive link, EMG was wirelessly recorded from the IMES as the monkey performed a finger flexion task.

Decoding individuated finger flexions with Implantable MyoElectric Sensors.

We trained a rhesus monkey to perform randomly cued, individuated finger flexions of the thumb, index, and middle finger. Nine Implantable MyoElectric Sensors (IMES) were then surgically implanted into the finger muscles of the monkey's forearm, without any observable adverse chronic effects. Using an inductive link, we wirelessly recorded EMG from the IMES as the monkey performed a finger flexion task.
