Evaluation of low-dose metronomic (LDM) cyclophosphamide toxicity in cats with malignant neoplasia

2014

Oral administration of low-dose cyclophosphamide in pets with spontaneously occurring malignant neoplasms has become a common practice in veterinary medicine. The purpose of this retrospective study was to investigate toxicity events in cats with spontaneous malignancies receiving cyclophosphamide as a metronomic therapy for at least 1 month. The number and severity of clinical, haematological and biochemical adverse events were recorded according to the Veterinary Cooperative Oncology Group’s Common Terminology Criteria for Adverse Events v1.1 classification scheme. Twenty-four cats were enrolled in the study with a total number of 27 neoplasms: 13 sarcomas, 12 carcinomas, one melanoma an…

GEC-ESTRO ACROP recommendations on calibration and traceability of LE-LDR photon-emitting brachytherapy sources at the hospital level

2019

Prostate brachytherapy treatment using permanent implantation of low-energy (LE) low-dose rate (LDR) sources is successfully and widely applied in Europe. In addition, seeds are used in other tumour sites, such as ophthalmic tumours, implanted temporarily. The calibration issues for LE-LDR photon emitting sources are specific and different from other sources used in brachytherapy. In this report, the BRAPHYQS (BRAchytherapy PHYsics Quality assurance System) working group of GEC-ESTRO, has developed the present recommendations to assure harmonized and high-quality seed calibration in European clinics. There are practical aspects for which a clarification/procedure is needed, including aspect…

Efficient 3D Deep Learning for Myocardial Diseases Segmentation

2021

Automated myocardial segmentation from late gadolinium enhancement magnetic resonance images (LGE-MRI) is a critical step in the diagnosis of cardiac pathologies such as ischemia and myocardial infarction. This paper proposes a deep learning framework for improved myocardial diseases segmentation. In the first step, we build an encoder-decoder segmentation network that generates myocardium and cavity segmentations from the whole volume, followed by a 3D U-Net based on Shape prior to identifying myocardial infarction and myocardium ventricular obstruction (MVO) segmentations from the encoder-decoder prediction. The proposed network achieves good segmentation performance, as computed by avera…

Reimbursement of radiotherapy in Germany.

2017

Reimbursement of radiotherapy in Germany is mainly based on a certain fixed fee for treatment planning and patient set up in addition to payment per fraction. This applies to outpatient care for patients with public health insurance or private health insurance. Payment per fraction has a considerable influence on reimbursement of inpatients as well. The advantage of payment per fraction is the simplicity and transparency. The disadvantage is an inadequate reimbursement for new treatment modalities like hypofractionation or stereotactic body radiotherapy.

Posttraumatic chronic cranial osteomyelitis due to a superficial wound - A clinical and neuroradiological case report

2019

Background: Osteomyelitis is a progressive infection of bone and bone marrow by microorganisms, resulting in inflammatory destruction of bone, bone necrosis, and new bone formation. Skull involvement is a rare occurrence which mainly affects children with chronic inflammatory diseases of paranasal sinusitis, or malignant otitis. In adults, cranial vault osteomyelitis can occur after cranial surgery or head trauma. Case Description: We describe an unusual case of chronic cranial osteomyelitis occurred 3 months following a mild traumatic brain injury. The causative mechanisms along with the diagnostic modalities are discussed. Conclusion: Focal cranial vault osteomyelitis, in the absence of …

Imaging of inner ear malformations: a primer for radiologists

2021

AbstractIn the multidisciplinary management of patients with inner ear malformations (IEMs), the correct diagnosis makes the differences in terms of clinical and surgical treatment. The complex anatomical landscape of the inner ear, comprising several small structures, makes imaging of this region particularly challenging for general radiologists. Imaging techniques are important for identifying the presence and defining the type of IEM and the cochlear nerve condition. High-resolution magnetic resonance imaging (MRI) sequences and high-resolution computed tomography (HRCT) are the mainstay imaging techniques in this area. Dedicated MRI and HRCT protocols play an important role in the diagn…
