Robotic En Bloc First-Rib Resection for Paget-Schroetter Disease, a Form of Thoracic Outlet Syndrome Technique and Initial Results
Objective
First-rib resection is a key component of the treatment of Paget-Schroetter disease. There are many controversies regarding the management of this disease. We report a safe, effective, minimally invasive robotic transthoracic approach for resection of the first rib.
Methods
Over an 8-month period, five patients underwent robotic first-rib resection. Preoperative assessment included physical examination and bilateral venous angiography. On a thoracoscopic platform using three 2-cm incisions and one 1-cm incision, the robot was used to dissect the first rib and divide the scalene muscles. Success of the first-rib resection was assessed by postoperative venous angiography.
Results
There were four men and one woman. Mean age was 34.6 ± 10 years. Mean operative time was 195 ± 24.6 minutes. There were no complications and no mortality. All patients had a patent subclavian vein on the postoperative venogram and were anticoagulated with warfarin for 3 months. At a median follow-up of 12 months, all patients had an open subclavian vein for a patency rate of 100%.
Conclusions
Robotic thoracoscopic first-rib resection represents a feasible minimally invasive approach to en bloc resection of the first rib. This technique minimizes the risk of neurovascular complications that are associated with conventional techniques

A highly virulent variant of HIV-1 circulating in the Netherlands
We discovered a highly virulent variant of subtype-B HIV-1 in the Netherlands. One hundred nine individuals with this variant had a 0.54 to 0.74 log10 increase (i.e., a ~3.5-fold to 5.5-fold increase) in viral load compared with, and exhibited CD4 cell decline twice as fast as, 6604 individuals with other subtype-B strains. Without treatment, advanced HIV-CD4 cell counts below 350 cells per cubic millimeter, with long-term clinical consequences-is expected to be reached, on average, 9 months after diagnosis for individuals in their thirties with this variant. Age, sex, suspected mode of transmission, and place of birth for the aforementioned 109 individuals were typical for HIV-positive people in the Netherlands, which suggests that the increased virulence is attributable to the viral strain. Genetic sequence analysis suggests that this variant arose in the 1990s from de novo mutation, not recombination, with increased transmissibility and an unfamiliar molecular mechanism of virulence
Track Reconstruction with Cosmic Ray Data at the Tracker Integration Facility
The subsystems of the CMS silicon strip tracker were integrated and commissioned at the Tracker Integration Facility (TIF) in the period from November 2006 to July 2007.
As part of the commissioning, large samples of cosmic ray data were recorded under various running conditions in the absence of a magnetic field.
Cosmic rays detected by scintillation counters were used to trigger the readout of up to 15\,\% of the final silicon strip detector, and over 4.7~million events were recorded.
This document describes the cosmic track reconstruction and presents results on the performance of track and hit reconstruction as from dedicated analyses
