RESUMEN
BACKGROUND: Chronic schistosomiasis silently leads to severe organ-specific disorders, such as hydroureter, bladder cancer or portal hypertension in around 10% of infected people in endemic zones. However, in non-endemic areas, information on schistosomiasis' severe complications and their actual prevalence is scarce because diagnosis is usually reached when such complications are well established. METHODS: Retrospective observational study of data obtained from a screening protocol designed for sub-Saharan migrants including search for stool parasites and schistosoma serology. After screening 3090 sub-Saharans, 326 (10.5%) confirmed cases of schistosomiasis were found, based on detection of ova in feces, urine or in biopsy samples. Another 830 patients (26.9%) were diagnosed of probable schistosomiasis (positive serology and/or suggestive imaging findings). RESULTS: Only patients with confirmed schistosomiasis were included in the final analysis. Among them, 13 (4%) presented severe complications at the time of diagnosis. Depending on the location, they account for 5% of patients with hepatointestinal schistosomiasis and 3.5% of patients with urogenital infection. CONCLUSIONS: Targeted systematic screening could reduce the prevalence of severe complications by enabling early diagnosis and treatment. Having indigenous transmission been demonstrated in southern Europe, prevention of future cases in non-endemic countries might be another sound reason supporting such screening.

OBJECTIVES: To achieve a better use of the packed red blood cells stock at our centre's blood bank, and to analyse cost-savings associated with the implementation of the type and screen (T/S) technology. METHODS: We analyse the results, complications and cost-savings achieved with the use of T/S at the Urology Department in our centre, for the transurethral resection of bladder tumour and prostate. RESULTS: A total of 232 T/S were performed; 3 patients required blood transfusions (1.3%). No complications appeared. Total cost-savings from December 1999 to December 2001 were 7.620 Euros (1,267,861.3 pesetas). CONCLUSIONS: T/S is a safe procedure allowing a better use of blood stocks in a hospital with a substantial economic saving.

OBJETIVOS: Conseguir una mejor utilización del stock de hematíes del Depósito de Sangre de nuestro centro y analizar el ahorro conseguido con la implantación de la metodología de Type and Screen (T/S).MÉTODOS: Analizamos los resultados de la utilización de T/S en la Unidad de Urología de nuestro centro en los procedimientos de resección transuretral de vejiga y próstata, las complicaciones presentadas y el ahorro conseguido. RESULTADOS: Se realizaron un total de 232 T/S, hubo que transfundir a 3 pacientes (1,3 per cent). No se presentó ninguna complicación. El ahorro conseguido fue de 7.620 E (1.267.861,3 pesetas) desde diciembre de 1999 a diciembre del 2001.CONCLUSIONES: El T/S es un procedimiento seguro que permite una mejor utilización de los depósitos de sangre de un hospital con un ahorro económico considerable (AU)
