[Associations Between Muscle Mass Levels and Functional Aspects in Non-Institutionalized Older Adults from Santiago, Chile].

Aim: To determine the relationship between the apendicular skeletal muscle mass and functional levels in non-institutionalized older adults in Santiago de Chile.

Methodology: This is a quantitative, non-experimental, descriptive correlational, cross-sectional study of 59 older adults (13 men and 46 women) who live in the community, particularly in Santiago, Chile. The muscle mass was estimated through anthropometric values and a predictive, validated equation for calculating Skeletal Appendicular Muscle Mass (MMAE).

Latin American formal consensus on the appropriate indications of extra-articular lateral procedures in primary anterior cruciate ligament reconstruction.

Objectives: To create a practice guideline for the appropriate indications of an extra-articular procedure in primary anterior cruciate ligament reconstruction (ACLR).

Methods: The formal consensus method described by the Haute Autorité de Santé was used. The Latin American Society of Arthroscopy, Articular Replacement, and Sports Injuries (SLARD) recruited three groups of experts on ACLR.

Eggshell membrane treatment for the healing of superficial open wounds in mice.

Introduction: Eggshell membranes offer beneficial properties for tissue regeneration and their biomedical applications are important. Objective: To demonstrate the effectiveness of hen unfertilized eggshell membranes in the treatment of superficial open wounds in mice compared to the conventional procedure. Materials and methods: 15-mm linear wounds were made on the back of 10 male CF-1 mice.

[Prognostic value of extracapsular lymph node involvement among patients with gastric cancer].

Background: Extracapsular lymph node involvement has a negative prognosis in malignant tumors.

Aim: To assess the prognostic importance of extracapsular lymph node involvement in patients with gastric cancer with lymph node metastases.

Material And Methods: Clinical and morphological features and survival of patients with gastric cancer and lymph node involvement operated between 1986 and 2003, were analyzed.

[Morphological findings in fatal cases of hantavirus cardiopulmonary syndrome. Report of 7 autopsies].

Introduction: Hantavirus cardiopulmonary syndrome (HCPS) is an acute infectious disease characterized by sudden cardiorespiratory failure and high mortality, caused by a RNA virus of the genus Hantavirus, family Bunyaviridae, 15% of Chilean cases have been detected in the Araucania Region.

Objective: To determine in fatal cases of HCPS, clinical and morphological characteristics.

Materials And Methods: Descriptive-retrospective analysis of seven fatal cases with postmortem study of HCPS, attended between 1997 and 2009 at the Hospital of Temuco, Chile.
