[Interventional sonography].

Interventional sonography describes the step from pure sonographic imaging diagnostics to sonographically controlled treatment that can be connected directly to sonographic imaging diagnostics instead of postponing it over a longer time interval with possibly further (X-ray, computed tomography, magnetic resonance imaging) diagnostics. The sonographically controlled interventional measures range from a simple puncture of fluid-filled spaces to infiltration of deeper lying areas, such as the labrum acetabulare, the dorsal knee joint capsule and facet joints up to infiltration of the sciatic nerve. The safety is guaranteed by adhering to clearly defined hygiene standards as well as by qualified training as part of the 3‑stage model of certification of the surgery section of the German Society of Ultrasound in Medicine (DEGUM).

The EFSUMB Guidelines and Recommendations for Musculoskeletal Ultrasound - Part II: Joint Pathologies, Pediatric Applications, and Guided Procedures.

The second part of the Guidelines and Recommendations for Musculoskeletal Ultrasound (MSUS), produced under the auspices of EFSUMB, following the same methodology as for Part 1, provides information and recommendations on the use of this imaging modality for joint pathology, pediatric applications, and musculoskeletal ultrasound-guided procedures. Clinical application, practical points, limitations, and artifacts are described and discussed for every joint or procedure. The document is intended to guide clinical users in their daily practice.

The EFSUMB Guidelines and Recommendations for Musculoskeletal Ultrasound - Part I: Extraarticular Pathologies.

The first part of the guidelines and recommendations for musculoskeletal ultrasound, produced under the auspices of the European Federation of Societies for Ultrasound in Medicine and Biology (EFSUMB), provides information about the use of musculoskeletal ultrasound for assessing extraarticular structures (muscles, tendons, entheses, ligaments, bones, bursae, fasciae, nerves, skin, subcutaneous tissues, and nails) and their pathologies. Clinical applications, practical points, limitations, and artifacts are described and discussed for every structure. After an extensive literature review, the recommendations have been developed according to the Oxford Centre for Evidence-based Medicine and GRADE criteria and the consensus level was established through a Delphi process.

Heart rate response to alarm tones in firefighters.

Objective: To examine cardiovascular responses to medical (MED) and fire (FIRE) alarm tones in firefighters.

Methods: Heart rate was collected throughout 24-h shifts (N = 41). Call logs were utilized post hoc to identify heart rate at the time the alarm sounded (TIME), peak heart rate following the alarm (TIME), and heart rate at the time of station departure (TIME) for MED and FIRE calls.

[Focused sonography in orthopedic emergencies].

Focused sonography of the musculoskeletal system in the emergency room should be done for time-effective and symptom-oriented detection of suspected findings. Analogous to other point-of-care ultrasound in emergency medicine, it is by definition not a complete ultrasound examination of the respective organ (e.g.

DEGUM Recommendations on Infection Prevention in Ultrasound and Endoscopic Ultrasound.

Microbial contamination of ultrasound probes for percutaneous or endoscopic use is common. However, infectious diseases caused by transmission of microorganisms by US procedures have rarely been reported. In Germany, legal regulations address hygiene in ultrasound procedures.

[The value of sonography in traumatology and orthopedics : Part 2: emergency diagnostics in blunt abdominal and thoracic trauma].

Ultrasound examinations in trauma patients should be done in the emergency department using curved-array (3.5-7.5 MHz) probes.

[Significance of sonography in traumatology and orthopedics: part 1: ultrasonography of the musculoskeletal system].

A wide variety of modern ultrasound systems - including linear probes (7.5-15 MHz) and curved array probes (3.5-7.

Vibrational molecular quantum computing: basis set independence and theoretical realization of the Deutsch-Jozsa algorithm.

The phase of quantum gates is one key issue for the implementation of quantum algorithms. In this paper we first investigate the phase evolution of global molecular quantum gates, which are realized by optimally shaped femtosecond laser pulses. The specific laser fields are calculated using the multitarget optimal control algorithm, our modification of the optimal control theory relevant for application in quantum computing.

Rotational state-dependent mixings between resonance states of vibrationally highly excited DCO (X2A').

Rotational state-dependent mixings between highly excited resonance states of DCO (X (2)A(')) were investigated by stimulated emission pumping spectroscopy via a series of intermediate rotational levels in the B (2)A(') electronic state of the radical. Two examples for such interactions, between pairs of accidentally nearly degenerate vibrational states at energies of E(v) approximately 6450 and E(v) approximately 10 060 cm(-1), respectively, were analyzed in detail. Deperturbations of the measured spectra provided the zeroth-order vibration-rotation term energies, widths, and rotational constants of the states and the absolute values of the vibrational coupling matrix elements.

Quantum computation with vibrationally excited molecules.

A new physical implementation for quantum computation is proposed. The vibrational modes of molecules are used to encode qubit systems. Global quantum logic gates are realized using shaped femtosecond laser pulses which are calculated applying optimal control theory.

Physiological disturbances at critically high temperatures: a comparison between stenothermal antarctic and eurythermal temperate eelpouts (Zoarcidae).

The effect of gradually increased water temperature on the metabolism of temperate eelpout from the North Sea (Zoarces viviparus) and Antarctic eelpout (Pachycara brachycephalum) was investigated. Standard metabolic rate (SMR) was similar in cold-adapted P. brachycephalum and cold-acclimated Z.

Systemic effects and side effects of interstitial techniques used in liver tissue.

Background: Percutaneous ethanol injection (PEI) and cryosurgery are increasingly used for the treatment of liver malignancies. To create a safety margin and to destroy completely diffusely growing tumors, the precise destruction of healthy liver tissue is necessary. Little is known about the effects of operating on this type of tissue.

[Pleural drainage in acute thoracic trauma. Comparison of the radiologic image and computer tomography].

Purpose: Estimation of chest tube placement in patients with thoracic trauma with regard to chest tube malposition in chest radiography in the supine position compared to additional computed tomography of the thorax.

Material And Methods: Apart from compulsory chest radiography after one or multiple chest tube insertions, 31 severely injured patients with thoracic trauma underwent a CT scan of the thorax. These 31 patients with 40 chest tubes constituted the basis for the present analysis.

Prospective randomized study of drainage and resection on non-occlusive segmental portal hypertension in chronic pancreatitis.

Background: In chronic pancreatitis, compression of the splenic vein and superior mesenteric vein (SMV) by an inflammatory mass may cause segmental portal hypertension. Drainage and resection are the principles of surgery for chronic pancreatitis. This study was devised to evaluate the effect of drainage and resection on venous splanchnic blood flow in patients with non-occlusive segmental portal hypertension.

Biochemical and molecular characterization of the extracellular esterase from Streptomyces diastatochromogenes.

An esterase of Streptomyces diastatochromogenes was purified to homogeneity from culture filtrate. The purified enzyme had a molecular mass of 30,862 +/- 5.8 Da, as determined by electrospray mass spectrometry.

[Open lymph vessels of the ligamentum falciforme hepatis in the human].

The falciform ligament and the ligamentum teres of the liver are the so-called ventral mesohepaticum. These ligaments are covered on both sides by one layer of mesothelial cells and consist of a dense network of lymphatic capillaries. Preparations of semithin sections were examined light microscopically, ultrathin sections by means of transmission electron microscopy and gold sputtered surface preparations by scanning electron microscopy.
