[Essential mixed cryoglobulinemia type II: case report.].

The cryoglobulinemic syndrome is produced by precipitating immunoglobulins at low temperatures. Its production is associated with several causes, such as lymphoproliferative disorders, chronic infections and autoimmune disorders. However, the etiology is unknow.

[Gallbladder ablation with a laser in an animal model].

Introduction: Attempts to remove the gallbladder by non-surgical means began in the 1980's, by applying chemicals, heat or laser to remove its mucosa and reduce it to an innocuous scar. The aim of this work is to determine whether complete ablation of this organ is possible using total ablation by applying a diode laser.

Material And Methods: Thirty rabbits were divided into 3 groups of 10 animals.

[Effect of UV index in the skin exposure].

This research was conducted from October 2003 to March 2005, collecting data through the measuring authorized volunteers measuring their photoexposition . It worked with the equipment (Safesun from Optix Tech, Inc.), available for measuring.

[Primary ovarian pregnancy (case report)].

A case of a patients is presented that consults for sharp abdominal pain that is intervened surgically with extirpation of a mass that commits the right annex. Histological preparations showed confirms ovarian pregnancy.

[Dermoepidermic junction: a selective, complex and vital barrier].

Dermoepidermic junction (DEJ) is a highly complex region, containing a great variety of cellular elements, which despite of having different embriogenesis, interact with each other, generating different substances that keep the function and homeostasis of the greatest organ of the human body. DEJ is regarded as a highly specialized basal lamina, which acts as a highly selective pathway for the migration of cells and macromolecules, inducing cellular differentiation and micro enviromental metabolism modifications. DEJ may be divided into three zones regarding the basal lamina 1--the nearest to epidermic zone, having tonofilaments and hemidesmosomes, which keep anchored basal cells.

[Decidua in the peritoneal surface mimicking metastatic nodules. Findings during cesarean section].

The occurrence of ectopic decidua has been observed most often in the ovaries, uterus, and cervix. A peritoneal localization is less frequent and usually an asymptomatic incidental finding. Ectopic decidua was investigated in biopsies taken during cesarean sections, elective tubal ligations, appendectomy and in tubal pregnancies.
