Stapled Hemorrhoidopexy: Technique and Long Term Results.

Stapled hemorrhoidopexy (Longo operation) is a infrequent technique in our area. A different concept from hemorrhoidectomy, a proportionally important raise in cost and a special training may have contributed to it. We report our long-term results with the standard technique.

Ethical considerations in bariatric surgery in a developing country.

Background And Aims: Obesity is the fastest growing health problem worldwide. Ethical issues linked to obesity are numerous and still under debate even in countries with a long history in obesity treatment.

Methods: From 2007 to 2015 we performed several types of bariatric surgical approaches on 250 patients with an average body mass index (BMI) of 42.

Bone mineral density, vertebral fractures and body mass index in postmenopausal women with abdominal aortic calcification.

Background: Evidence suggest that there are connections between osteoporosis and cardiovascular diseases.

Objectives: The aim of the study was to analyze the relationship between radiological measurements of abdominal aorta calcifications (AAC) and bone mineral density (BMD) in postmenopausal women.

Methods: In this cross-sectional study were included 125 postmenopausal women 50-84 years of age.

Building phylogenetic trees by using gene Nucleotide Genomic Signals.

Nucleotide genomic signal (NuGS) methodology allows a molecular level approach to determine distances between homologous genes or between conserved equivalent non-coding genome regions in various species or individuals of the same species. Therefore, distances between the genes of species or individuals can be computed and phylogenetic trees can be built. The paper illustrates the use of the nucleotide imbalance (N) and nucleotide pair imbalance (P) signals to determine the distances between the genes of several Hominidae.

[Transanal endoscopic microsurgery--our initial experience].

Unlabelled: The aim of this study was to describe a single institution's experience with transanal endoscopic microsurgery (TEMS) in patients with benign and malignant rectal tumors.

Material And Method: This was a prospective descriptive survey. Between January 2006 and January 2010, 14 patients underwent transanal endoscopic microsurgery excision of benign (8) or malignant (6) rectal tumors, located 4 to 15 cm from the dentate line.
