Drain fluid cultures can rule in but cannot rule out infection persistence after surgical treatment of periprosthetic joint infections.

Background: Periprosthetic joint infection (PJI) is one of the most common reason for implant failure in arthroplasty. Surgical therapy is essential but there is no standardized guideline to determine infection eradication in multiple-step revision surgery. To date, clinical and laboratory inflammation markers and preoperative arthrocentesis are controversial to evaluate the infection status before reimplantation and therefore are often combined.

CT based PSI blocks for osteotomies around the knee provide accurate results when intraoperative imaging is used.

Purpose: Correction osteotomies around the knee are common methods for the treatment of varus or valgus malalignment of the lower extremity. In recent years, patient specific instrumentation (PSI) guides were introduced in order to enhance the accuracy of these procedures. The purpose of this study was to determine the accuracy of CT based PSI guides for correction osteotomies around the knee of low volume osteotomy surgeons and to evaluate if CT based PSI blocks deliver a high degree of accuracy without using intraoperative fluoroscopy.

• Pancho trial (p53-adapted neoadjuvant chemotherapy for resectable esophageal cancer) completed-mutation rate of the marker higher than expected.

Background: In operable esophageal cancer patients, neoadjuvant therapy benefits only those who respond to the treatment. The • Pancho trial represents the first prospective randomized trial evaluating the relevance of the mark53 status for predicting the effect of two different neoadjuvant chemotherapies.

Method: Biomarker analysis was conducted using the mark53 analysis.

Mechanism and rate of the reaction CH3 + O--revisited.

The primary products and the rate of the reaction of methyl radicals with oxygen atoms in the gas phase at room temperature have been studied using three different experimental arrangements: (A) laser flash photolysis to produce CH3 and O from the precursors CH3I and SO2 (the educts and the products were detected by quantitative FTIR spectroscopy); (B) the coupling of a conventional discharge flow reactor via a molecular sampling system to a mass spectrometer with electron impact ionization, which allowed the determination of labile and stable species; (C) laser induced multiphoton ionization combined with a TOF mass spectrometer-molecular beam sampling-flow reactor, which was used for the specific and sensitive detection of the CH3, CD3, C2H5 and C2D5 radicals and the determination of rate coefficients. The branching ratio of the reaction channels was determined by the experimental arrangements (A) and (B) leading to CH3 + O --> HCHO + H (55 +/- 5)% --> CO + H2 + H (45 +/- 5)%. The rate coefficients of the normal and deuterated methyl and ethyl radicals with atomic oxygen showed no isotope effect: k(CD3 + O)/k(CH3 + O) = 0.

Smoke/burn injury-induced respiratory failure elicits apoptosis in ovine lungs and cultured lung cells, ameliorated with arteriovenous CO2 removal.

Study Objective: s: The purpose of this study was to examine the effects of two supportive therapies, conventional mechanical ventilation (CMV) and arteriovenous CO(2) removal (AVCO(2)R), during treatment of severe smoke/burn injury-induced ARDS.

Design: Sheep were exposed to a smoke/burn injury (lethal dose causing death in 40% of animals); lung tissue and blood was collected prior to injury (control), when an ARDS criterion was met (PaO(2)/fraction of inspired oxygen ratio < 200), then after 72 h of either CMV (group 1) or AVCO(2)R (group 2). Lung tissue was studied by standard histopathologic techniques; cultured lung cells were studied in media supplemented with serum from all four groups.

[Aneurysm of the popliteal vein].

Venous aneurysms are a rare pathology. The possible complications are rupture, thrombosis and subsequently pulmonary embolism. The case of a 54-year-old male is reported, who was admitted on the suspicion of pulmonary embolism to our department.

Speech processing in radiology.

The goal of this study was to evaluate the recognition rate, learning potential and amount of time needed to complete a report with the Philips speech recognition system SP 6000 (Philips, Best, The Netherlands). Four radiologists dictated reports of interventional radiology, MRI examinations of the musculoskeletal system and CT examinations of the thorax and abdomen with the Philips system using the German language. The recognition rate of each report and improvement rate after each learning phase of the Philips system was assessed.

[Surgical treatment of infrarenal abdominal aortic aneurysm].

Results of surgical treatment of infrarenal abdominal aortic aneurysms (AAA) have improved in recent years. Through worldwide experience associated risk factors could be determined and reduced significantly. Therapy of associated diseases and profound morphologic knowledge about AAA are the most important factors to influence survival after surgery.

Blood viscoelasticity response during carotid endarterectomy.

As demonstrated in many studies ischemic brain injury causes microcirculatory disturbances which is reflected in changes in the rheological behavior of blood. This is caused by multifactorial interaction between blood cells and damaged endothelium in the capillary network with release of tissue metabolites and by-products of cellular injury with resulting increased cellular permeability producing a volume shift into the interstitium and, subsequently, a rise in the hematocrit density. Drop in perfusion pressure produces an increase in whole blood viscosity.

Distal popliteal and tibioperoneal transluminal angioplasty: long-term follow-up.

The long-term efficacy of percutaneous transluminal angioplasty (PTA) for treatment of occlusive lesions involving arteries below the knee was evaluated in 168 consecutive patients. The procedure was preceded by intraarterial thrombolysis in 33 patients with failing femorodistal grafts. Indications were disabling claudication in 40 cases (24%), acute ischemia in 18 (11%), rest pain in 49 (29%), and tissue necrosis in 61 (36%).

Deep venous thrombosis: results of thrombectomy versus medical therapy. Presented at the 5th European-American Symposium on Venous Diseases, Vienna, Austria, Nov. 7-11, 1990.

Surgical management of perforating diverticular disease in Austria.

Perforated diverticulitis is a much feared complication of diverticular disease and requires immediate surgical therapy to limit the incipient peritonitis and its sequelae. The ensuing surgical approach which could best irradiate the septic focus as well as restore normal intestinal continuity with less morbidity and mortality has been a matter of controversy. In the last ten years primary resection and colostomy has replaced the three-stage procedure in most cases of peritonitis.

[Pelvic lipomatosis--its appearance on radiography and computed tomography (author's transl)].

Case report on a case of pelvic lipomatosis, the 21. case published in the world literature. The typical radiographic findings, such as deformity of the urinary bladder and the abnormal course of the sigma, were seen.

[Continuous monitoring of the pulmonary artery pressure in acute myocardial infarction (author's transl)].

The method of continuous pulmonary artery pressure (PAP) monitoring and its use in 66 patients with acute myocardial infarction is described. Measurement of PAP should be the first diagnostic step in hemodynamic monitoring and early recognition of left ventricular failure. In cases of elevated PAP and critical general state of the patient, monitoring should be extended by measuring pulmonary wedge pressure and cardiac output.
