Wound Closure After Port Implantation-A Randomized Controlled Trial Comparing Tissue Adhesive and Intracutaneous Suturing.

Background: Wound healing after pectoral port implantation is a major factor determining the success or failure of the procedure. Infection and wound dehiscence can endanger the functionality of the port system and impede chemotherapy. The cosmetic result is important for patient satisfaction as well.

Deviations in positioning variable pitch screws- scaphoid waist fractures.

Introduction: Operative therapy using a headless cannulated variable pitch compression screw is the gold standard for the treatment of instable scaphoid fractures.

Hypothesis: Deviation from the central placement is associated with a loss of stability and stiffness.

Material And Methods: An artificial bone model was manufactured and different screw positions (central, 10° and 20° to the long axis) were assessed.

Acute atraumatic carpal tunnel syndrome due to flexor tendon rupture following palmar plate osteosynthesis in a patient taking rivaroxaban.

Introduction: Few case reports describe the development of a hematoma under oral anticoagulation as the cause of an atraumatic carpal tunnel syndrome.

Case Report: A 76 years old woman presented an acute atraumatic carpal tunnel syndrome of her left hand under oral anticoagulation with rivaroxaban due to atrial fibrillation. 12 years ago, palmar plate osteosynthesis of a distal radius fracture had been performed on the affected wrist.

Quantitative sensory testing after macroreplantation: evidence for a specific somatosensory profile.

A comprehensive functional recovery is one of the criteria for successful replantation of an amputated limb. Functionality of a replanted limb is strongly dependent on its regained sensibility. In previous studies concerning the sensibility of replanted limbs, only a few somatosensory submodalities were examined in small samples.

The plasma environment inside geostationary orbit: A Van Allen Probes HOPE survey.

The two full precessions in local time completed by the Van Allen Probes enable global specification of the near-equatorial inner magnetosphere plasma environment. Observations by the Helium-Oxygen-Proton-Electron (HOPE) mass spectrometers provide detailed insight into the global spatial distribution of electrons, H, He, and O. Near-equatorial omnidirectional fluxes and abundance ratios at energies 0.

Whistler anisotropy instabilities as the source of banded chorus: Van Allen Probes observations and particle-in-cell simulations.

Magnetospheric banded chorus is enhanced whistler waves with frequencies <Ω , where Ω is the electron cyclotron frequency, and a characteristic spectral gap at ≃Ω /2. This paper uses spacecraft observations and two-dimensional particle-in-cell simulations in a magnetized, homogeneous, collisionless plasma to test the hypothesis that banded chorus is due to local linear growth of two branches of the whistler anisotropy instability excited by two distinct, anisotropic electron components of significantly different temperatures. The electron densities and temperatures are derived from Helium, Oxygen, Proton, and Electron instrument measurements on the Van Allen Probes A satellite during a banded chorus event on 1 November 2012.

Cortical reorganization after macroreplantation at the upper extremity: a magnetoencephalographic study.

With the development of microsurgical techniques, replantation has become a feasible alternative to stump treatment after the amputation of an extremity. It is known that amputation often induces phantom limb pain and cortical reorganization within the corresponding somatosensory areas. However, whether replantation reduces the risk of comparable persisting pain phenomena as well as reorganization of the primary somatosensory cortex is still widely unknown.

Wheelbarrow tire explosion causing trauma to the forearm and hand: a case report.

Introduction: Tire explosion injuries are rare, but they may result in a severe injury pattern. Case reports and statistics from injuries caused by exploded truck tires during servicing are established, but trauma from exploded small tires seems to be unknown.

Case Presentation: A 47-year-old german man inflated a wheelbarrow tire.

Above-Knee Replantation Following Traumatic Bilateral Amputation: Sciatic Nerve Transplantation.

A 12-year-old boy who was overrun by a train, sustained traumatic bilateral above-knee amputation and a rupture of the symphysis. The left leg had multiple fractures and soft tissue injuries and amputation was necessary. The right one, although severely crushed, at the amputation site and with a MESS of 9, was replanted accepting some shortening and a soft tissue defect at the amputation site, employing saphenic vein grafts from the amputate (left leg) and an early free latissimus dorsi-flap.

Indocyanine-green fluorescence video angiography used clinically to evaluate tissue perfusion in microsurgery.

Background: Laser-induced fluorescence angiography with indocyanine-green (ICG-FA) is a new diagnostic approach that allows quantitative evaluation of tissue perfusion in microsurgery as well as an analysis of the uptake, distribution, and clearance of dye-marked blood.

Methods: The ICG-FA technique was evaluated for its sensitivity and prognostic value in comparison with clinical parameters (turgor, temperature, reperfusion time, bleeding after puncture) during and after different surgical procedures. Altogether, 91 measurements were made in cases of microvascular repair (n = 43) and free-flap surgery (n = 48).
