The onset of a large number of cases of brucellosis among employees at a slaughterhouse in Zaragoza where sheep from livestock culling procedures were being slaughtered, led to an investigation being ...made for the purpose of shedding light on the cause of this outbreak.
This study was organized into three parts: 1) Description of the outbreak 2) Study of the slaughterhouse layout and activity as regards the number of animals slaughtered, the employee workload and the degree of risk involved in each working area and 3) Unmatched case-control study.
No significant differences were found among the attack rates by the sections of the slaughterhouse where the employees in question worked. The slaughtering analysis revealed a concomitant fluctuation between the slaughter of culled sheep and the epidemic. The case-control study revealed no significant differences for the risk factors involving working in a risk area, the use of protective measures and cuts/wounds.
This outbreak is related to the slaughter of culled sheep. The fact that no significant difference were found by sections or due to working in a risk area is compatible with an overall explanation. Nor were any differences among the employees found to exist with regard to cuts/wounds or the use of protective measures, which focuses importance on airborne spread.
FUNDAMENTO: La aparición de un número elevado de casos de brucelosis entre los trabajadores de un matadero en Zaragoza, en el que se sacrificaba ganado ovino procedente de las campañas de saneamiento ...ganadero, hizo iniciar una investigación para esclarecer el origen del brote. MÉTODOS: El estudio se estructuró en tres partes: 1) Descripción del brote; 2) Estudio de la estructura y actividad del matadero en cuanto al número de animales sacrificados, carga de trabajo del personal y riesgo por zona de trabajo y 3) Estudio de casos y controles no apareado. RESULTADOS: No hubo diferencias significativas entre las tasas de ataque por secciones de trabajo. El análisis del sacrificio reveló una variación concomitante entre las curvas de sacrificio de ovino de saneamiento y la epidémica. El estudio de casos y controles no reveló diferencias significativas para los siguientes factores de riesgo: trabajo en zona de riesgo, uso de medidas de protección y realización de cortes y heridas. CONCLUSIONES: El brote está relacionado con el sacrificio de ovino de saneamiento. El que no se observaran diferencias significativas por secciones o por trabajar en la zona de riesgo es compatible con una exposición generalizada. Tampoco se observaron diferencias entre los trabajadores respecto a la realización de cortes y heridas o el uso de medidas de protección, lo que da importancia a la transmisión aérea.
To review renal graft obstruction post-transplantation and its surgical management.
Our experience and those of other Spanish centers are analyzed and the literature reviewed. The different causes of ...obstruction following transplantation are briefly analyzed and the advantages and disadvantages of the different therapeutic options are discussed.
Graft obstruction post-transplantation continues to be an important challenge to the urologist. However, in most of the cases the therapeutic alternatives are relatively standardized and achieve satisfactory results.
An unusual case of retroperitoneal fibrosis with non-obstructive anuria is described and the therapeutic alternatives are discussed. METHODS/ RESULTS: Repeated obstruction of the double-J ureteral ...catheter and intense lumbar pain did not permit endourological management and surgery was required. Excellent results were achieved and the patient is asymptomatic 12 months postoperatively.
Conservative endourological management and corticosteroids may not always be feasible. The anuria without dilation in the case described is not unlike other reported cases considered as reflex anuria whose mechanism remains unknown.

The higher risk of developing malignant tumours in transplanted patients is a fact widely acknowledged over the last decade. This paper includes an analysis of our series and a review of the ...literature. Cancers developed by the transplanted patient or "de novo" cancers and, within this group skin and lip cancer (58%), are by far the most frequent ones. Their biological behaviour is, in general, more aggressive than similar ones in non-transplanted population. Also, different incidence rates and behaviour have been established depending on the immunosuppressive regime given to the patient. Most common pre-existing carcinoma was renal cancer (one third of cases). When these patients had been adequately treated before the transplant, the minimum disease-free interval that has to elapse to be included in a waiting list will depend on the type of tumour. Transferred tumours are the least frequent but more worrying ones due to both their clinical and legal implications. In view of the existing evidence, it is of particular relevance to insure the primitive nature of any CNS tumour as well as the absence of tumoral disease in young females who die of brain haemorrhage.
We present uretero-pyeloplasty as a new surgical approach to stricture of the pyelo-ureteric junction in the transplant recipient. The foregoing is more frequently found in kidneys that are placed in ...the inverted anatomic position. The surgical procedure is performed without difficulty and at the same time permits us to evidence the presence of a new ureteral revascularization from the recipient after the interruption of vascular supply of the donor kidney.
An additional case of signet ring cell adenocarcinoma of the bladder is described. This tumor type is considered to be uncommon; however, recent studies have reported a higher incidence. The ...etiopathogenesis and clinical features are discussed. Because it is silent and very aggressive, it is always diagnosed late and the outcome is poor. Treatment is by surgery since radio and chemotherapy have been shown to be little effective.
