Chest wall reconstruction in benign and malignant tumors with non-rigid materials: An overview.

Several materials and techniques have been described for the procedure of chest wall reconstruction: the choice of using a technique or a material over another relies mainly on the surgeon's experience as well as thoracic defect localization and dimension, local availability of materials, and costs. From a technical point of view, autologous and alloplastic reconstruction are available, and, in both cases, rigid and non-rigid prostheses are found. Each material has its peculiarities, with advantages and disadvantages; thus, it is mandatory to be confident when planning the intervention to foresee possible complications and minimize them.

Social inequalities in the metropolitan area of Rome. A multidisciplinary analysis of the urban segregation of the "formerly-Bastogi" compound.

Background: This study tries to evaluate, through a multidisciplinary approach, the relationship between urban structure, isolation and distribution of social determinants of health, in the so-called "formerly-Bastogi, a compound, with more than 1,500 inhabitants, located in north-western Rome, Italy.

Methods: The architectural-urban analysis, conducted through site visits and evaluations of urban situation, showed how strongly the compound is isolated from the neighbourhoods, and structurally degraded. The socio-demographic analysis, based on the National Census data, showed significant differences in the distribution of the social determinants of health between "formerly-Bastogi" and the surrounding areas.

Impact of damming on the Chironomidae of the upper zone of a tropical run-of-the-river reservoir.

We examined the effects of the Mogi-Guaçu river damming (São Paulo State, Brazil) on the Chironomidae fauna. Pre, during, and post-filling sampling was carried out in the main channel and margins of one site in the upper zone of the reservoir, using a modified Petersen grab (325 cm2). We evaluated the total, subfamily, and tribe densities and also their relative abundance.
