Rechazo medidado por anticuerpos en el trasplante pulmonar: serie de 21 casos

El rechazo mediado por anticuerpos (RMA) es una entidad establecida en el trasplante de órgano sólido (TOS), especialmente en el renal o cardíaco pero con controversias en otros como trasplante pulmonar (TP). Veintiún TP de un total de 207 entre 1990 y octubre de 2012 presentaron RMA (10%); todos presentaron disfunción clínica del injerto y criterios anatomo-patológicos; 8 de 17 (47.1%) con tinción C4d positiva y 7 de 21 (33.3%) con anticuerpos donante específicos. El tratamiento específico administrado fue la combinación de plasmaféresis, inmunoglobulinas y rituximab. Cuatro pacientes (19%) fueron éxitus por RMA y 13 (62%) presentaron mejoría clínica y funcional.

Proyecto de una explotación frutal de 21 ha en Albelda (Huesca)

Transformació d´ una explotació mitjançant la plantació de fruiters, la instal•lació d´una infraestructura de reg i la construcció de una nau-magatzem.

La finca ocupa una superfície total de 21 ha, de les quals 8,6 ha es dedicaran a la implantació de perer y 10,3 ha a la de poma, a la resta de la superfície s´ hi faran els camins de la finca i la nau magatzem.

Traumatic bone cyst: a retrospective study of 21 cases

Objective: To describe the clinical and radiological characteristics, and surgical findings of traumatic bone cysts. Study Design: A retrospective observational study was made of 21 traumatic bone cysts. The diagnosis was based on the anamnesis, clinical examination, and complementary tests. Panoramic and periapical X-rays were obtained in all cases, together with computed tomography as decided by the surgeon. A descriptive statistical analysis was made of the study variables using the SPSS v12.0 for Windows. Results: There was a clear female predominance (14:7). The mean age was 26.5 years (range 8-45 years). The cysts in all cases constituted casual findings during routine radiological exploration. In those cases where computed tomographic images were available, preservation of the vestibular and lingual cortical layers was observed. Five of the 21 patients (23.8%) reported a clear antecedent of traumatism in the affected zone. All the lesions were subjected to surgery, and the cavities were found to be vacant in 90.5% of the cases. In only two patients were vascular contents seen within the cavity. Two of the patients presented postoperative paresthesia of the inferior dental nerve that subsided within two weeks. The 19 patients in whom adequate postoperative follow-up proved possible all showed complete bone healing. Conclusions: Traumatic bone cysts were a casual finding. During the surgery, most cases showed to be vacant cavity without an ephitelial lining. Careful curettage of the lesion favors progressive bone regeneration, offering a good prognosis and an almost negligible relapse rate. Other treatment options only would be justified in cases of relapse.
