Cadaver as an experimental a model for the study of midline incisional hernia.

Purpose: To describe a cadaver model and to compare different techniques to correct midline incisional hernia using the tension at the musculoaponeurotic layer as a parameter.

Methods: Twenty-four male cadavers were used to characterize the model. The tensile force applied to the anterior layers of the rectus abdominis muscle was measured after the linea alba was resected to create an abdominal wall defect.

Mapping traction strength of the anterior rectus sheath in cadaver.

Purpose: The tension at the aponeurotic edges of abdominal wall defects is an important factor of dehiscence and incisional hernia formation. The purpose of this study is to map and compare the traction force necessary for medial mobilization in various levels of the anterior rectus sheath in cadavers.

Methods: Twenty four adult male cadavers, raging from 22 to 59 years old, with the abdominal wall intact and without prior preservation techniques, were dissected.

[Anthropometric assessments in dental esthetics].

Various parameters related to the mobility of the upper lip in a sample of 200 patients, have been considered in order to establish the correlation these have with the extent of lip mobility and the relative visibility of their teeth. From this study it was clear that a large number of patients, with a low index of tooth visibility, could benefit, from the viewpoint of their periodontal health, from the application of prosthetic margins above the gums. This would not damage the aesthetic aspect because the margins in question would only be visible with the lips contracted or, in certain patients, never.

[Gingival fibromatosis. A clinical, therapeutic and histopathological study of a new case].

The aetiopathogenesis, histology and clinical treatment of a rare case of familial gingival fibromatosis are analysed with particular emphasis on the relationship between the histological picture and the pathogenesis of the condition. In tackling the problem of treatment, the paper recommends the use of gingivectomy with an internal rather than the classic external chamfer.
