Non Uniqueness of Power-Law Flows.

We apply the technique of convex integration to obtain non-uniqueness and existence results for power-law fluids, in dimension . For the power index below the compactness threshold, i.e.

Non-uniqueness for the Transport Equation with Sobolev Vector Fields.

We construct a large class of examples of non-uniqueness for the linear transport equation and the transport-diffusion equation with divergence-free vector fields in Sobolev spaces .

INFLUENCE OF TOBACCO, ALCOHOL AND DIABETES ON THE COLLAGEN OF CREMASTER MUSCLE IN PATIENTS WITH INGUINAL HERNIAS.

Background: New findings point out that the mechanism of formation of the hernias can be related to the collagenous tissues, under activity of aggressive agents such as the tobacco, alcohol and diabetes.

Aim: To analyze the collagen present in the cremaster muscle in patients with inguinal hernias, focusing the effect of tobacco, alcohol, and diabetes.

Methods: Fifteen patients with inguinal hernia divided in three groups were studied: group I (n=5) was control; group II (n=5) were smokers and/or drinkers; and group III (n=5) had diabetes mellitus.

Class III gynecomastia in pediatric age: a new modified surgical treatment.

Background: Prepubertal gynecomastia is an extremely rare condition usually requiring surgical treatment, especially in case of class III gynecomastia. This study presents cases treated with a new surgical treatment.

Methods: From 2010 at our institution, gynecomastia is treated surgically using a modified technique of periareolar incision.

[Spontaneous rupture of the esophagus: Boerhaave's syndrome].

Boerhaave's syndrome, the spontaneous rupture of the esophagus, is associated with a 35% death rate. Perforated esophagus is a surgical emergency; it is the most serious, and frequently the most rapidly lethal, perforation of the gastro-intestinal tract. Three cases of Boerhaave's syndrome are presented, with their variants and resolutions.
