Aerobiological and clinical study in the semidesertic area of the Southeastern of Spain.

Aerobiological studies constitute a relevant tool to predict the most influential parameters over the pollen seasons with significant clinical relevance in the allergic populations. The aim of this study was to describe the aerobiological behaviour of the most relevant allergenic sources in the semi-arid area of southeast of Spain (Almería) and to investigate the correlation with meteorological factors and clinical symptoms of allergic patients. Daily pollen count and meteorological parameters of Almería, Spain, were compiled for ten years. The clinical symptoms of 248 allergic patients were also recorded. Descriptive statistics and correlations between variables were assessed. Multivariate analyses were performed to predict the influence of meteorological factors on pollen concentration and the risk of suffer respiratory symptoms. Eight pollen families were identified as the most relevant allergenic sources. Temperature correlated with main pollen season evolution of all taxa whereas rainfall and relative humidity only correlated in Oleaceae, Pinaceae, Amaranthaceae, Asteraceae and Urticaceae. Rainfall and relative humidity were the most influential predictors of pollen concentration, except in Amaranthaceaea and Poaceae families, while temperature only influenced on Cupressaceae and Urticaceae pollen concentrations. A significant positive influence was observed between maximum temperature and rainfall with the appearance of allergic symptoms in patients sensitized to grasses, Parietaria sp. and Olea sp. This study, highlight the main aerobiological features in the region and establish a suitable tool for clinical follow-up and management of allergic patients. Further studies are needed to establish an accurate measurement aimed to control and prevent pollinosis in sensitized patients.

Lipoleiomiosarcoma en región paratesticular. Estudio de dos casos y revisión de la literatura / Lipoleiomyosarcoma in the paratesticular region. Presentation of two cases and a review of the literature

El lipoleiomiosarcoma corresponde a un liposarcoma bien diferenciado que muestra focalmente diferenciación hacia tejido muscular liso maduro con atipia. La localización característica es el retroperitoneo, aunque se han descrito casos en otras localizaciones, siendo raros en la región inguinal-paratesticular. El comportamiento de las lesiones es similar al liposarcoma bien diferenciado, siendo clave en el pronóstico de la lesión la localización y, en relación a esta, la posibilidad o no de extirpación quirúrgica completa. Presentamos dos casos de localización paratesticular y revisamos la literatura(AU)

Lipoleiomyosarcoma is a well differentiated liposarcoma with focal differentiation into mature smooth muscle with atypia. These tumours usually occur in the retroperitonum, although they have been reported in other locations. The inguinal paratesticular region is a rare site for these neoplasms. Their behaviour is similar to that of well differentiated liposarcomas. Their location and the possibility of complete surgical extirpation are key prognostic factors. Two cases of lipoleiomyosarcoma occurring in the paratesticular region are presented together with a review of the literature(AU)
