Importance: Although active surveillance for patients with low-risk prostate cancer (LRPC) has been recommended for years, its adoption at the population level is often limited.
Objective: To make active surveillance available for patients with LRPC using a research framework and to compare patient characteristics and clinical outcomes between those who receive active surveillance vs radical treatments at diagnosis.
Design, Setting, And Participants: This population-based, prospective cohort study was designed by a large multidisciplinary group of specialists and patients' representatives.
In order to improve fit and comfort, a maxillary protraction facemask customized to the patient's anatomy was produced by means of 3D face scanning, digital design and additive manufacturing. An 8-year-old patient in need of early treatment for the Class III malocclusion received a rapid palatal expander and a Petit-type facemask, whose components were digitally designed on a 3D scan of the patient's face. For face scanning, the iPad Pro 2018 tablet (Apple, Cupertino, CA, USA) with the Bellus3D DentalPro application (Bellus3D, Campbell, CA, USA) was used.

We aimed to characterize -mutant, IO-naive CRC.

The aim of this study was to examine the pattern and cellular localization of PD-L1 expression in the different molecular subtypes of mismatch-repair-deficient colorectal cancers vs. their mismatch-repair-proficient counterparts.

North American provincial and state laboratories have well-defined roles and responsibilities, including providing accurate, timely test results for patients and information for regional public health and other decision makers. We used the multidisciplinary response and rapid implementation of process changes based on Lean methods at the provincial public health laboratory in British Columbia, Canada, to improve laboratory surge capacity in the 2009 influenza pandemic.

Patients And Methods: There were 271 consecutive patients who were enrolled in this prospective study. Patients were randomized to emergency ureteroscopy (group A) or delayed ureteroscopy (group B).
As the world prepares for the next influenza pandemic, governments have made significant funding commitments to vaccine development and antiviral stockpiling. While these are essential components to pandemic response, rapid and accurate diagnostic testing remains an often neglected cornerstone of pandemic influenza preparedness. Clinicians and Public Health Practitioners need to understand the benefits and drawbacks of different influenza tests in both seasonal and pandemic settings.

Patients And Methods: A feasibility study was conducted in which EPX was administered in 21-day continuous infusion to 15 patients with HRPC.
Introduction: In recent years there has been a shift in prostate cancer stage with the majority of patients nowadays being operated with cT1c disease, prostate-specific antigen levels of <10 ng/ml, and a decreased rate of seminal vesicle invasion. Recent data suggest the role of preservation of the seminal vesicle in improving continence and/or potency. We describe our preliminary experience with seminal-sparing, unilateral nerve-sparing retropubic radical prostatectomy.

Objective: To evaluate the effect of levofloxacin (LVX) oral therapy on total serum prostate specific antigen (PSA) values in patients with histological prostatitis.
Materials And Methods: All consecutive outpatients with histological evidence of chronic prostatitis, total PSA > 4 ng/ml, normal DRE and urinalysis and treated once daily with LVX 500 mg per os for 20 days were retrospectively evaluated for total serum PSA reduction. A decrease of PSA value > 5% was considered correlated with the antibiotic therapy.
Objectives: The prognostic role of the invasion of the urinary collecting system (UCS) by renal cell carcinoma (RCC) has not attracted a notable amount of attention. The aim of this study was to investigate incidence and prognostic value of UCS involvement in RCC.
Material And Methods: All pathological reports of radical nephrectomies performed in two centres of urology from November 1983 to December 1999 were reviewed in order to evaluate the invasion of the UCS (calices, renal pelvis, ureter).
Residual feed intake (RFI) has been proposed as an index for determining beef cattle energetic efficiency. Although the relationship of RFI with feed conversion ratio (FCR) is well established, little is known about how RFI compares to other measures of efficiency. This study examined the phenotypic relationships among different measures of energetic efficiency with growth, feed intake, and ultrasound and carcass merit of hybrid cattle (n = 150).
View Article and Find Full Text PDFThe incidence of prostate cancer is remarkably increased in the last decade. This dramatic epidemiological change can be primarily attributed to the widespread use of prostate specific antigen (PSA) as a diagnostic tool. Nowadays most of the prostate cancers are detected at an early stage and the age of the patients is decreased.

Patients And Methods: We reviewed the operative and pathology reports of 725 patients with RCC submitted for RN. All tumours were classified using the fifth edition of the Tumour-Nodes-Metastasis classification.
Purpose: Previous in vitro investigations recorded an inhibition of cell proliferation by BCG when added to different cell cultures. The induction of apoptosis by BCG is controversial. Our study aimed to evaluate the influence of BCG on the expression of tumor suppressing proteins p53 and p21Waf1-Cip1 and apoptosis of the urothelial cells in vivo.

In the bladder cancer the most important prognostic factors are the stage, the grade, the presence or absence of lymph nodal metastasis, the response to therapy with B. C. G.

Methods: Ten patients with biopsy-proven HCC were treated with 20-min HAI of doxorubicin (17 total treatments). Two patients were treated with doxorubicin 60 mg/m2, three patients were treated at 90 mg/m2, and five patients received 120 mg/m2.
Tumour resistance to chemotherapeutic drugs through expression of the multidrug resistance phenotype is a major impediment in the treatment of hepatic malignancies. We performed hepatic arterial infusion of verapamil (at a dose known to block P-glycoprotein activity) and doxorubicin combined with complete hepatic venous isolation and extracorporeal chemofiltration in non-tumour-bearing pigs with normal livers to evaluate the pharmacology and toxicology of this drug combination. The complete hepatic venous isolation-chemofiltration system significantly reduced system exposure to both verapamil and doxorubicin (P < 0.
