PROSTATOSYMPHYSEAL FISTULA AFTER TRANSURETHRAL RESECTION OF THE PROSTATE

2001

The formation of a urethrosymphyseal fistula is a rare complication after transurethral resection of the prostate. It may develop secondary to previous radiation therapy of the pelvis. We describe a case of spontaneous fistula formation after transurethral resection of the prostate. CASE REPORT

Impact of the Tiloop Bra mesh in CT images and dose delivery in breast radiotherapy

2012

A new titanized breast mesh, TiLOOP Bra, is currently available for implantation in patients who require radiotherapy. The purpose of this work is to study the dosimetric effect of the presence of a TiLOOP Bra mesh on breast radiation treatment and radiographic imaging. The dosimetric effects have been measured for three X‐ray energies: 1.25 MeV, 6 MV and 18 MV, using radiochromic films placed at three different depths. These depths are representative of mesh location in breast during the radiotherapy treatment and hence, are of interest in this study. In order to assess the disturbance in a radiographic image, different computed tomographic (CT) studies of the mesh have been performed. The…

Technical development in cardiac CT: current standards and future improvements—a narrative review

2020

Non-invasive depiction of coronary arteries has been a great challenge for imaging specialists since the introduction of computed tomography (CT). Technological development together with improvements in spatial, temporal, and contrast resolution, progressively allowed implementation of the current clinical role of the CT assessment of coronary arteries. Several technological evolutions including hardware and software solutions of CT scanners have been developed to improve spatial and temporal resolution. The main challenges of cardiac computed tomography (CCT) are currently plaque characterization, functional assessment of stenosis and radiation dose reduction. In this review, we will discu…

The combination of chemotherapy and radiotherapy towards more efficient drug delivery.

2013

Research on anticancer therapies has advanced significantly in recent years. New therapeutic platforms that can further improve the health of patients are still highly demanded. We propose the idea of combining regular chemotherapy with radiation therapy to minimize side effects as well as increase drug-delivery efficiency. In this Focus Review, we seek to provide an overview of recent advances that can combine chemotherapy and radiotherapy. We begin by reviewing the current state of systems that can combine chemotherapy and gamma radiation. Among them, diselenide-containing polymers are highlighted as sensitive drug-delivery vehicles that can disassemble under gamma radiation. Then X-ray r…

Prevention and treatment of oral mucositis in patients receiving chemotherapy

2013

Oral mucositis is one of the most common side effects of cancer treatment (chemotherapy and/or radiotherapy). It is an inflammatory process that affects the mucosa of the oral cavity, giving rise to erythematous areas in combination with ulcers that can reach a large size. The true importance of oral mucositis is the complications it causes – fundamentally intense pain associated to the oral ulcers, and the risk of overinfection. This in turn may require reduction or even suspension of the antineoplastic treatment, with the risk of seriously worsening the patient prognosis. This points to the importance of establishing therapeutic tools of use in the prevention and/or treatment of mucositis…

Prognostic factors in the treatment of Ewing's sarcoma

1987

From 1981 up to February 1985, a total of 93 protocol patients entered the study CESS 81. The protocol recommended an initial 18-week period of polychemotherapy (VACA) followed by local therapy and two additional cycles of chemotherapy. Local therapy consisted either of radical surgery or of incomplete resection plus postoperative irradiation with 36 Gy or of radiotherapy alone (46 and 60 Gy). Centrally located lesions were always irradiated with 60 Gy. This article summarizes the data after 5 years. Data of 93 patients were analysed in October 1986 after a median follow-up of 37 months. The projected 5-year survival is 50%. The relapse rate was 42%, distant relapses occurred in 19%, local …

Retroperitoneal neuroblastomas - a single institution experience in 90 patients

2007

Purpose Nowadays neuroblastomas are detected incidentally by ultrasound in early stages. Primary surgery, chemotherapy and/or radiotherapy are treatment options. However, the approach in babies is controversial. A surveillance strategy is propagated by some groups. In this retrospective study, we evaluated age and stage at diagnosis, therapy and outcome of patients treated at our institutions since 1970. Material and methods 90 patients with retroperitoneal neuroblastomas were treated. They were divided into 2 groups according to age at time of diagnosis:  1 year. Results 40 patients were  1 year (1- 18 years). Detection of an asymptomatic tumour:  1 year 10%. Tumor stage at diagnosis > 1 y…
