Project Name: Quantitative and Qualitative Analysis of Bacterial Load Contamination in Breast Implant Surfaces and Capsular Tissue

Project Summary:
Breast augmentation is the most common cosmetic surgery performed in the United States. The role of bacterial contamination on breast implant surfaces has been associated with device-associated infection including the capsular contracture and breast implant-associated anaplastic lymphoma (BIAALCL). Critically, it is not well understood what the relative degree of total bacterial load that exist between an implant and it’s capsular tissue. The purposes of this investigation are: 1) to quantitatively and qualitatively analyze the bacterial contamination between the breast implant and its respective capsular tissue; 2) determine whether the implant or the capsular tissue has the greatest capacity for maintaining a bacterial load of the breast pocket; 3) qualitatively and qualitatively analyze the effectiveness of povidone iodine-triple antibiotic irrigation in decreasing the bacterial load of capsular tissue. We hypothesize that the bacterial contamination on the breast implant  ill be significantly higher than in the capsular tissue, and that povidone iodine antibiotic irrigation will significantly decrease the bacterial load in the capsule. Clinically, these data are  essential when treating a variety of breast implant cases, particularly common patients currently seen who are asymptomatic and wanting to exchange textured implants or want to  have their capsules removed for a variety of reasons.
 
Power-asisted Liposuction Vibration Exposure and Safety Guidelines Print

Researcher: Rolando Morales, MD

Amount Awarded: $4,300

Project Name: Power-asisted Liposuction Vibration Exposure and Safety Guidelines

Project Summary:

Plastic surgeons are increasingly exposed to the hazard of hand-transmitted vibration as liposuction gains popularity, specifically for those using power-assisted liposuction (PAL) devices. With long-term use, this increases the risk of developing a group of insidious neurovascular symptoms termed hand-arm vibration syndrome (HAVS). HAVS manifests in debilitating and irreversible numbness and later painful vasospasm of the fingers (Raynaud’s phenomenon). Therefore, it is important to determine the safety limits and establish standardized guidelines for long-term exposure to PAL-associated vibration because the development of HAVS can be detrimental to a plastic surgeon’s career.

The proposed study will examine vibration emission of a commonly used PAL device under varying conditions of use in order to make relevant recommendations for plastic surgeons to minimize the risk of developing HAVS. This will be examined in the experiments of the following specific aims:

Aim 1: Determine PAL system vibration emission under various controlled conditions compared to manufacturer’s declared values.
Rationale: PAL manufacturers publish only one vibration emission value, however this measured under controlled laboratory conditions and will not be consistent under different conditions of use. These conditions include vibration of the handle without an attached cannula and with attached cannulas of different lengths/diameters.
Hypothesis: Vibration emission value will measure higher with increasing length and diameter of the cannula attached.

Aim 2: Determine PAL system vibration exposure under true conditions of use during surgery.  
Rationale: Vibration at the handle will change depending on the resistance applied at the cannula tip. For example, the PAL handle vibrates less intensely when the cannula is in the air compared to when it is being driven through fibrous tissue during surgery.
Hypothesis: Vibration exposure will measure higher during actual surgical use of the PAL system than that estimated from manufacturer specifications.

Aim 3: Create PAL surgical safety guidelines to minimize the risk of vibration induced health hazards for surgeons
Rationale: It is important to inform plastic surgeons about the use of PAL and the risk of HAVS as an occupational hazard. Vibration exposure during actual surgical use of the PAL system will differ from manufacturer calculations, therefore more accurate guidelines for safe surgical use should be calculated from on-the-job surgical data collected from this study.

Hypothesis: PAL surgical safety guidelines from this study will estimate a shorter safe duration of use compared to manufacturer guidelines.
