Internet Addiction: Starting the Debate on Health and Well-Being of Children Overexposed to Digital Media.
2017
Previous articles published in the European Paediatric Association (EPA) pages have discussed the importance of children's well-being and its role in different areas of children's health, such as well-child care and child-friendly health care. The goal of this commentary is to raise pediatricians' awareness on the risks of children's overexposure to digital media. It is important to protect the psychological and emotional health of children from uncontrolled external influences to preserve their well-being. We also emphasize the importance of alerting parents and tutors to the risks related to the unrefrained use of the Internet.
A paradigm shift: from disease to health orientation
2006
The history of science has been described as 'paradigm shifts' of sequential overthrow, each new paradigm replacing the previous one. A paradigm is an overarching view-point which guides the articulation of theories and other activities in a particular field. In the exploration of health, two different types of approach can be identified. The pathogenic view, which has dominated the orientation of medicine over the last hundred years, focuses on disease states and underlying factors that modify the chances of entering into one of those states. The competing salutogenic view appears to be undergoing a renaissance in the new strategies of public health and health promotion, and producing theo…
A multiparametric magnetic resonance imaging-based virtual reality surgical navigation tool for robotic-assisted radical prostatectomy
2019
Objective Increased computational power and improved visualization hardware have generated more opportunities for virtual reality (VR) applications in healthcare. In this study, we test the feasibility of a VR-assisted surgical navigation system for robotic-assisted radical prostatectomy. Material and methods The prostate, all magnetic resonance imaging (MRI) visible tumors, and important anatomic structures like the neurovascular bundles, seminal vesicles, bladder, and rectum were contoured on a multiparametric MRI using an in-house segmentation software. Three-dimensional (3-D) VR models were rendered and evaluated in a side room of the operating room. While interacting with the VR platfo…
Resección extendida y exenteración pélvica en el cáncer de recto del tercio inferior
2014
Approximately 10% of all low rectal cancer needs surgical resection extended to other pelvic structures. Indication for extended resection should be given according to a precise systemic and local preoperative staging. Magnetic Resonance Imaging is the most important instrument utilized by the Multidisciplinary Team to decide therapeutic strategy according to the surgical risk. The status of the pathological circumferential resection margin is the most important prognostic factor determining local recurrence risk and oncological outcome and for this reason it should be considered pivotal in the decision of the strategy of treatment. When extended resection is performed, the presence of an e…
Robot-Assisted Transvesical Enucleation of Benign Prostatic Hyperplasia: Lessons from a Single Surgeon’s Learning Curve
2014
Abstract Introduction Open simple prostatectomy is a well-established and effective operation for prostate volumes greater than 80 gm but also associated with bleeding and urinary incontinence. To benefit from the advances of laparoscopy, robot-assisted simple prostatectomy was established. We determined the learning curve of this minimally invasive surgery by evaluating the first procedures by an experienced robotic surgeon. Methods Patients presenting for surgical therapy with prostate volumes greater than 80 gm were considered for the study. Evaluation included validated questionnaires preoperatively, and at 6 and 12 weeks postoperatively. Blood loss, transfusions, operation time and pad…
The percentage of free prostate-specific antigen does not predict extracapsular disease in patients with clinically localized prostate cancer before …
2001
Objective To determine whether the percentage of free/total prostate-specific antigen (f/tPSA) can predict the pathological features in patients with clinically localized prostate cancer before radical prostatectomy. Patients and methods Univariate and multivariate logistic regression was used to analyse data from 171 untreated patients who underwent radical prostatectomy. Variables included the total PSA (tPSA), fPSA, f/tPSA, biopsy Gleason score, clinical stage and patient age. Results In 115 patients with pathologically organ-confined tumours ( pT2N0) the mean (sd) tPSA value was 6.9 (5.6) ng/mL; in 56 patients with extracapsular disease ( pT3pN0/N+) it was 10.2 (7.6) ng/mL; the respecti…
Zonal Segmentation of Prostate T2W-MRI using Atrous Convolutional Neural Network
2019
The number of prostate cancer cases is steadily increasing especially with rising number of ageing population. It is reported that 5-year relative survival rate for man with stage 1 prostate cancer is almost 99% hence, early detection will significantly improve treatment planning and increase survival rate. Magnetic resonance imaging (MRI) technique is a common imaging modality for diagnosis of prostate cancer. MRI provide good visualization of soft tissue and enable better lesion detection and staging of prostate cancer. The main challenge of prostate whole gland segmentation is due to blurry boundary of central gland (CG) and peripheral zone (PZ) which lead to differential diagnosis. Sinc…
Variations PSA Value in Patients Candidate to Biopsy of the Prostate
2005
Subclinical infections of the prostate can increase the prostate-specific antigen (PSA) values in patients with normal digital rectal examination. This study aimed to evaluate the role of short-term antimicrobial therapy in reducing the PSA value in patients as candidates for transrectal biopsy. Fifty-eight patients with negative digital rectal examination and PSA values between 4 and 20 ng/mL were included in the study. Antibiotics were administered to all patients for 3 weeks, and the PSA was reassessed 10 days after the end of the treatment. Patients were subsequently submitted to prostate biopsy. A reduction in PSA was detected in 34 patients (59%). Mean percentage reduction was 32%. I…
Overview of Venous Thromboembolism
2010
Thrombosis occurs at sites of injury to the vessel wall, by inflammatory processes leading to activation of platelets, platelet adherence to the vessel wall and the formation of a fibrin network. A thrombus that goes on to occlude a blood vessel is known as a thromboembolism. Venous thromboembolism begins with deep vein thrombosis (DVT), which forms in the deep veins of the leg (calf) or pelvis. In some cases, the DVT becomes detached from the vein and is transported to the right-hand side of the heart, and from there to the pulmonary arteries, giving rise to a pulmonary embolism (PE). Certain factors predispose patients toward the development of venous thromboembolism (VTE), including surg…
Pharmacokinetic Study on Adenomatous Prostate Tissue Concentrations of Cef operazone
1989
Cephalosporins do not reach active therapeutical concentrations in the prostatic tissue in patients suffering from chronic bacterial prostatitis. Cefoperazone is an exception. Its efficacy in the trea
