Ultrasound-Guided Intramural Inoculation of Orthotopic Bladder Cancer Xenografts: A Novel High-Precision Approach

2013

Orthotopic bladder cancer xenografts are essential for testing novel therapies and molecular manipulations of cell lines in vivo. Current xenografts rely on tumor cell inoculation by intravesical instillation or direct injection into the bladder wall. Instillation is limited by the lack of cell lines that are tumorigenic when delivered in this manner. The invasive model inflicts morbidity on the mice by the need for laparotomy and mobilization of the bladder. Furthermore this procedure is complex and time-consuming. Three bladder cancer cell lines (UM-UC1, UM-UC3, UM-UC13) were inoculated into 50 athymic nude mice by percutaneous injection under ultrasound guidance. PBS was first injected b…

Congenital Pediatric Diseases

2008

Major congenital malformations are diagnosed in 4%–6% of all infants and fetuses (Lynberg and Edmonds 1992). About one third of them are the leading cause for infant mortality or morbidity (Grandjean et al. 1999). Malformations of the internal urogenital system are diagnosed in about 1% of all infants and account for approximately 20% of all congenital malformations, thus being one of the three most frequent birth defects (Table 11.1.1). Therefore a pre- and/or postnatally performed ultrasound screening for malformations of the internal urogenital system should be part of the routine to reduce perinatal mortality and morbidity. The reliability and value of ultrasonographic screening for con…

Pediatric Urinary Diversion: Review and Own Experience

1992

New insights into the diseases of childhood, profound improvements and new developments in surgical techniques as well as the knowledge gained from long-term follow-up have altered the strategies and indications for urinary diversion in childhood. Continent urinary diversion is generally the method of choice. We are able to construct high capacity, low pressure reservoirs to protect the upper urinary tract and achieve continence. Nowadays, there is hardly any indication for permanent cutaneous urinary diversion. Temporary and intermediate cutaneous diversion are used only when serious conditions such as renal function deterioration occur. The possibility to convert any incontinent form of u…

Infections caused by Pseudomonas aeruginosa: relatively frequent isolation of serogroup 12 from clinical specimens.

1985

Serological typing of P. aeruginosa is the most simple and reliable procedure recommended for ≪ in-house ≫ investigations and for studies of suspected outbreaks of infection by this microorganism. It is also a useful procedure in order to know serotype prevalence in a definite geografical area and to obtain indications about the more appropriate composition of polivalent anti-Pseudomonas vaccines. In the present report, we describe the relatively high frequency of isolation of serogroup 12 from patients in Palermo, Italy. Serogroup 12 is very rare in north-Europe and in the USA, and, as a consequence, it is not included in some vaccine preparations. In Palermo, strains belonging to this ser…

Histochemical Geography and Ultrastructural Remarks of the Urinary Tract in Some Mammals

2008

Our investigations oriented towards the urinary tracts, particulary the bladder and ureter, were carried out by histochemical and ultrastructural studies by SEM and TEM observation. In this segment of urinary tract, by structural, ultrastructural and chemical analysis, have evinced variations related to different animal species (guinea pig, rabbit and rat). The bladder wall was considered from us for histochemical aspects related to hydrolytic lysosomial enzymes (Ac-Phase; Na-beta-Gase) and oxidative enzymes (SDH; Iso-DH; MADH) and ultrastructural aspect with TEM. The SEM observations showed the connection between morphovolumetric variations of uroepithelial cells and respiratory enzymatic …

Management of urinary incontinence in postmenopausal women: An EMAS clinical guide.

2020

INTRODUCTION: The prevalence of urinary incontinence and of other lower urinary tract symptoms increases after the menopause and affects between 38 % and 55 % of women aged over 60 years. While urinary incontinence has a profound impact on quality of life, few affected women seek care. AIM: The aim of this clinical guide is to provide an evidence-based approach to the management of urinary incontinence in postmenopausal women. MATERIALS AND METHODS: Literature review and consensus of expert opinion. SUMMARY RECOMMENDATIONS: Healthcare professionals should consider urinary incontinence a clinical priority and develop appropriate diagnostic skills. They should be able to identify and manage a…

E.coli, K.pneumoniae un P. aeruginosa antimikrobiālā rezistence urīnceļu infekcijās

2018

Fons: 2015. gadā PVO ieviesa Globālo mikrobu rezistences uzraudzības sistēmu (GLASS). 2017. gadā to pirmoreiz ieviesa Latvijā. Mērķi: Raksturot pašreizējo situāciju attiecībā uz antimikrobiālo rezistenci, multirezistenci kā arī ESBL (plaša spektra beta laktamāzes) producētājus urīnceļu infekcijām, ko izraisa E. coli, K. pneumoniae un P. aeruginosa un analizēt saistību ar pacienta vecumu, dzimumu un infekcijas izcelsmi. Materiāli un metodes: Kopskaitā tika analizēti 924 urīna paraugi no Paula Stradiņa Klīniskās universitātes slimnīcas, 2016. gadā (731 — E. coli, 147 — K. pneumoniae, 46 — P. aeruginosa). Rezultāti: E. coli rezistences procentuālās daļas: amikacīns: 0,3%, ceftazidīms: 13,8%, c…

Olive oil intake and cancer risk: A systematic review and meta-analysis

2022

Background Research evidence has established the beneficial effects of diet in cancer prevention; various epidemiological studies have suggested that olive oil component could play a role in decreasing cancer risk. This systematic review and meta-analysis aims to investigate the association between olive oil consumption, cancer risk and prognosis. Methods A systematic search was conducted in PubMed, EMBASE and Google Scholar databases (end-of-search: May 10, 2020). Pooled relative risk (RR) and 95% confidence intervals (95% CIs) were estimated with random-effects (DerSimonian-Laird) models. Subgroup analyses, sensitivity analyses and meta-regression analysis were also performed. Results 45…
