Feasibility of image-guided radiotherapy based on tomotherapy for the treatment of locally advanced anal carcinoma

The standard of care for locally advanced anal cancer has been concurrent chemoradiation. However, conventional treatment with 3-dimensional radiotherapy is associated with significant toxicity. The feasibility of new radiotherapy techniques such as image-guided radiotherapy (IGRT) in combination with chemotherapy for the treatment of this malignancy was assessed.

Phase I clinical and pharmacokinetic evaluation of the vascular-disrupting agent OXi4503 in patients with advanced solid tumors

Preclinical studies show that OXi4503 (combretastatin A1 diphosphate, CA1P) is more potent than other clinically evaluated vascular-disrupting agents.

Comparative effectiveness of cisplatin-based and carboplatin-based chemotherapy for treatment of advanced urothelial carcinoma

Cisplatin-based chemotherapy is a standard treatment of metastatic urothelial carcinoma (UC), though carboplatin-based chemotherapy is frequently substituted due to improved tolerability. Because comparative effectiveness in clinical outcomes of cisplatin- versus carboplatin-based chemotherapy is lacking, a meta-analysis was carried out.

Advanced nail surgery

Six techniques not yet widely known or used in the dermatologic surgery of the nails are briefly described. Small-to-medium-sized tumours of the proximal nail fold (PNF) can be excised and the defect repaired with advancement or rotation flaps. A superficial biopsy technique of the matrix for the diagnosis of longitudinal brown streaks in the nail, which allows rapid histological diagnosis of the melanocyte focus to be performed, is described here. Because the excision is very shallow and leaves the morphogenetic connective tissue of the matrix intact, the defect heals without scarring. Laterally positioned nail tumours can be excised in the manner of a wide lateral longitudinal nail biopsy. The defect repair is performed with a bipedicled flap from the lateral aspect of the distal phalanx. Malignant tumours of the nail organ often require its complete ablation. These defects can be covered by a full-thickness skin graft, reversed dermal graft, or cross-finger flap. The surgical correction of a split nail is often difficult. The cicatricial tissue of the matrix and PNF have to be excised and the re-attachment of these wounds prevented. The matrix defect has to be excised and sutured or covered with a free matrix graft taken either from the neighbouring area or from the big toe nail.

Advanced heart failure - treatment options beyond medical management

Improvement of heart failure therapy has led to a far better survival and quality of life of patients. Treatment of the underlying disease, patient education and improvement of compliance and consequent upgrading of medical heart failure therapy often delays further progression to an advanced stage of heart failure. Nevertheless heart failure remains a chronic progressive disease and it is up to the treating clinician to identify the signs of advanced heart failure in a timely manner in order to evaluate patients for further treatment strategies such as heart transplantation. This article should help define advanced heart failure and illustrate how patients are evaluated for further therapy. Outcome of heart transplantation or mechanically assisted circulatory support is strongly associated to proper patient selection and timing.

Advanced morphological 3D magnetic resonance observation of cartilage repair tissue (MOCART) scoring using a new isotropic 3D proton-density, turbo spin echo sequence with variable flip angle distribution (PD-SPACE) compared to an isotropic 3D steady-state free precession sequence (True-FISP) and standard 2D sequences

To evaluate a new isotropic 3D proton-density, turbo-spin-echo sequence with variable flip-angle distribution (PD-SPACE) sequence compared to an isotropic 3D true-fast-imaging with steady-state-precession (True-FISP) sequence and 2D standard MR sequences with regard to the new 3D magnetic resonance observation of cartilage repair tissue (MOCART) score.

Swiss multidisciplinary and multilingual experience of the Advanced Trauma Life Support course: lessons for Europe

Courses in the Advanced Trauma Life Support are a well-accepted concept throughout the world for training in the emergency treatment of polytraumatized patients. Switzerland, a multilingual country with a long tradition of multidisciplinary collaboration in trauma care, introduced its first student courses in 1998. Unlike some countries where the courses are attended only by surgeons, instructors and students in Switzerland include surgeons, anaesthetists and physicians from other specialties.

The GABRIEL Advanced Surveys: study design, participation and evaluation of bias

Exposure to farming environments has been shown to protect substantially against asthma and atopic disease across Europe and in other parts of the world. The GABRIEL Advanced Surveys (GABRIELA) were conducted to determine factors in farming environments which are fundamental to protecting against asthma and atopic disease. The GABRIEL Advanced Surveys have a multi-phase stratified design. In a first-screening phase, a comprehensive population-based survey was conducted to assess the prevalence of exposure to farming environments and of asthma and atopic diseases (n = 103,219). The second phase was designed to ascertain detailed exposure to farming environments and to collect biomaterial and environmental samples in a stratified random sample of phase 1 participants (n = 15,255). A third phase was carried out in a further stratified sample only in Bavaria, southern Germany, aiming at in-depth respiratory disease and exposure assessment including extensive environmental sampling (n = 895). Participation rates in phase 1 were around 60% but only about half of the participating study population consented to further study modules in phase 2. We found that consenting behaviour was related to familial allergies, high parental education, wheeze, doctor diagnosed asthma and rhinoconjunctivitis, and to a lesser extent to exposure to farming environments. The association of exposure to farm environments with asthma or rhinoconjunctivitis was not biased by participation or consenting behaviour. The GABRIEL Advanced Surveys are one of the largest studies to shed light on the protective 'farm effect' on asthma and atopic disease. Bias with regard to the main study question was able to be ruled out by representativeness and high participation rates in phases 2 and 3. The GABRIEL Advanced Surveys have created extensive collections of questionnaire data, biomaterial and environmental samples promising new insights into this area of research.
