Bone Resorption after Use of Silicone Chin Implants, Long-term Follow-up Study with Lateral Chin Radiography.

Silicone chin implants are frequently used in cosmetic surgery to enhance a harmonic face. Obtaining an aesthetically pleasing face is increasingly becoming more important for people, and a considerable part of this goal can be achieved through different aesthetic modifications of the chin. The purpose of this study was to analyze the presence of bone resorption after the insertion of silicone chin implants, with lateral chin radiographs.

Older women do not have seasonal variations of vitamin D levels: a study from a southern country.

Objective: The aim was to study whether the seasonal variation of vitamin D [25(OH)-D or calcidiol] is similar or different in younger and older women living in a southern country.

Methods: Measurement of serum 25(OH)-D concentration in 739 Chilean women aged 20 to 87 years, residents of Santiago (latitude: 33.4° South) who, during a routine gynaecological checkup, agreed to be evaluated.

Effects of Abdominoplasty on Intra-Abdominal Pressure and Pulmonary Function.

Background: Abdominal wall weakness is a consequence of rectus abdominis diastasis and flaccidity of the myofascial component. A degree of plicature of the rectus abdominis generates an increase of intra-abdominal pressure (IAP), which may result in an increase of intrathoracic pressure, thus affecting thoracic hemodynamics and leading to inadequate ventilation.

Objectives: To assess changes generated by plicature of the rectus abdominis on IAP and pulmonary function in patients undergoing abdominoplasty.
