The sigma rectum pouch (Mainz pouch II)
1996
A low-pressure reservoir for urine is created by antimesenteric splitting and side-to-side anastomosis of the rectosigmoid, the expectation being to obtain better continence rates and better protection of the upper tract than are achievable by ureterosigmoidostomy. Between 1990 and August 1993 the procedure was performed in 73 patients (59 adults and 14 children) whose mean age was 43.5 years. The indications were malignancy (n = 55), bladder exstrophy/epispadias (n = 14), trauma (n = 3), and sinus urogenitalis (n = 1). Of the 73 patients, 69 were followed for a mean period of 127 (range, 1-34) months. In all, 5 early complications were encountered (6.8%). In addition, 8 late complications …
Vitamin metabolism in patients with a Mainz pouch I: long-term followup.
1997
We assessed whether creation of the Mainz pouch I, which requires 24 to 36 cm. of terminal ileum and 12 cm. of ascending colon including the ileocecal valve, leads to metabolic disturbances.In 137 patients the levels of vitamins A, B1, B2, B6, B12, D and E, folic and bile acids, ammonia, and intracorpuscular vitamin B12 and folic acid were evaluated and a red blood count was performed. Patients were divided into children and adults, and into 3 groups according to number of years after surgery (2 or less, more than 2 to 4 and more than 4).In all patients the levels of vitamins A, B1, B2, B6, D and E, folic and bile acids, and ammonia as well as red blood count were within normal ranges. In t…
Long-Term Results of Ileocecal Continent Urinary Diversion in Patients Treated With and Without Previous Pelvic Irradiation
2002
Patients who receive pelvic irradiation may require urinary diversion to manage complications resulting from progressive malignancy or radiotherapy. The choice of urinary diversion is an important issue and remains controversial. We characterized the long-term outcome of urinary diversion with a continent ileocecal reservoir in patients who received pelvic irradiation versus those who underwent urinary diversion without previous irradiation.Continent urinary diversion with an ileocecal reservoir (Mainz pouch 1) was performed in 36 irradiated patients in a 9-year period. Morbidity, mortality, the reoperative rate and parameters associated with the surgical procedure were determined at a medi…
Sexual Function and Fertility of Women with Classic Bladder Exstrophy and Continent Urinary Diversion
2015
We evaluated the outcome in female patients with classic bladder exstrophy and continent urinary diversion for sexual function and fertility.We reviewed the medical records of female exstrophy patients who underwent continent urinary diversion in our department between 1969 and 2014. Patients were invited for followup examination and asked to complete questionnaires relating to sexual function, social integration and maternity.Of 38 eligible patients 29 (response rate 76%) with a followup of 22.3 years were included in study. Primary continent urinary diversion was done in 62% of patients and 38% underwent secondary continent urinary diversion after failed reconstruction of the exstrophic b…
The Relevance of Mineral Mobilization and -Dissolution on the Reservoir Quality of Sandstones in CO2 Storage Sites
2014
Abstract Rotliegend siliciclastic formations are important reservoirs in central Europe. These sediments consist of pristine red coloured and bleached, high porous and permeable sandstones. To evaluate the relevance of distinct fluids and their fluid-rock alteration reactions on such bleaching processes laboratory static batch experiments under reservoir conditions were conducted. Thereby mineralogical, petrophysical and (hydro-, geo-) chemical rock features were investigated by different analytical methods before and after the experiments. The achieved results suggest that during such fluid-rock interactions a complex interplay between mineral detachment and mineral dissolution processes w…
First survey on zoonotic helminthosis in urban brown rats (Rattus norvegicus) in Spain and associated public health considerations.
2018
Abstract The brown rat, Rattus norvegicus, with a worldwide distribution, is the most commensal species among synanthropic rodents, since its main habitat, in urban as well as in rural areas, is always linked to humans. Therefore, people living in close proximity to rodent populations can be exposed to infection. Whereas bacteria and viruses are the best known rat-associated zoonoses in urban environments, the role of brown rats as reservoirs for helminth parasites and the associated risk for humans are less well known. Specifically, this role has not been analyzed in Spain to date. A total of 100 R. norvegicus trapped in the sewage system (n = 85), and parks (n = 15) of Barcelona was exami…
Phytoplankton distribution along trophic gradients within and among reservoirs in Catalonia (Spain)
2008
SUMMARY 1. Longitudinal gradients in the epilimnetic waters of stratified reservoirs provide a useful database to study changing environmental conditions. The spatial distribution, assemblage structure and specific adaptations of phytoplankton assemblages can be analysed along these gradients over short time scales. 2. Four reservoirs with a similar typology, located along an altitudinal gradient in the same eco-region, were sampled along their longitudinal axes. In total, 19 sampling stations provided a trophic spectrum, ranging from oligo-mesotrophy to hypertrophy, which was quantified by calculating the trophic state index of each sampling station in the four reservoirs. 3. Several patte…
Quality of life following urinary diversion: Orthotopic ileal neobladder versus ileal conduit. A multicentre study among long-term, female bladder ca…
2019
Abstract Introduction Women undergoing radical cystectomy (RC) followed by urinary diversion (UD) for bladder cancer experience a substantial reduction in health-related quality of life (HRQOL). At present, studies comparing long-term QOL outcomes for different UD methods, needed to inform evidence-based choices of bladder reconstruction for female patients, are sparse. Our objective was to compare two common UD methods in terms of their HRQOL outcomes in women. Materials and methods We retrospectively analysed HRQOL in 73 consecutive female bladder cancer patients having undergone orthotopic ileal neobladder (IONB, N = 24) or ileal conduit (IC, N = 49) following RC between 2007 and 2013 in…
Fascioliasis in Llama, Lama glama, in Andean Endemic Areas: Experimental Transmission Capacity by the High Altitude Snail Vector Galba truncatula and…
2021
Simple Summary The infection by the liver fluke Fasciola hepatica in South American camelids, mainly llamas and alpacas, has been the focus of many studies. However, their capacity to participate in the transmission of the disease and their potential reservoir role in human or animal endemic areas have never been studied. Therefore, all development stages of an isolate from Argentine llama of the high Andean plateau have been experimentally investigated, from egg embryogenesis to metacercarial infectivity, by using the vector snail Galba truncatula from the high altitude Bolivian Altiplano human hyperendemic area. Although eggs shed by llamas may successfully develop until the adult stage i…
Relationships between host species and morphometric patterns in Fasciola hepatica adults and eggs from the northern Bolivian Altiplano hyperendemic r…
2001
The highest prevalences and intensities of human fasciolosis by Fasciola hepatica are found in the northern Bolivian Altiplano, where sheep and cattle are the main reservoir host species and pigs and donkeys the secondary ones. Morphometric comparisons of many linear measurements, areas and ratios of F. hepatica adults (from sheep, cattle and pigs) and eggs (from sheep, cattle, pigs and donkeys) in natural liver fluke populations of the Bolivian Altiplano, as well as of F. hepatica adults and eggs experimentally obtained in Wistar rats infected with Altiplanic sheep, cattle and pig isolates, were made using computer image analysis and an allometric model. Although morphometric values of adu…
