Background: As the popularity of aesthetic gluteoplasty continues to grow, there is renewed focus on defining the ideal buttocks. However, the literature lacks studies characterizing an ideal thigh, despite the impact of thigh contour on overall gluteal aesthetic.

Objectives: The authors performed the first population analysis of the characteristics of perception of attractive thighs, to identify a role for fat grafting of the thigh in gluteoplasty.

Background: Several studies have demonstrated that progressive tension sutures (PTS) reduce seroma. Many fear that adding liposuction to abdominoplasty will increase seroma rates and avoid drainless abdominoplasty when performing concomitant liposuction.

Objectives: We sought to identify whether liposuction increases seroma in PTS and non-PTS abdominoplasty.

Background: Abdominoplasty is a common aesthetic procedure in the United States. Pollock and Pollock described their progressive tension technique in 2000 and published a series of 597 patients in 2012 of their experience. The reported seroma rate in the literature ranges from 2% to 26% with drains and 0.

Article Synopsis
  • The article discusses the challenges of breast augmentation alongside skin tightening, highlighting the complexity of combining these procedures for better aesthetic results.
  • Increasing patient interest and new surgical approaches have made combined augmentation-mastopexy more popular, leading to a rise in follow-up surgeries for initial augmentations.
  • The authors outline the reasons for secondary augmentation-mastopexy, safe techniques for the procedure, additional supportive procedures, common issues that may arise, and ways to address complications.

Background: Despite the increasing popularity of the combined augmentation mastopexy procedure among patients, the safety and efficacy of this surgery have been questioned by many surgeons.

Objective: The authors investigated the safety and efficacy of the combined augmentation mastopexy procedure.

Methods: The authors retrospectively reviewed the medical records of 615 consecutive patients who underwent combined augmentation mastopexy procedures at a single outpatient surgery center from 1992 through 2011.

Perforator flaps are preferable for breast reconstruction after mastectomy in many patients. Preoperative imaging of the perforators and source vessels is desirable to reduce surgeon stress, limit donor and recipient site complications, and minimize operative time and associated costs. Computed tomographic angiography (CTA) has been shown to provide highly accurate representations of vascular anatomy with excellent spatial resolution.

Background: To assess if diagnostic laparoscopy (DL) is superior to nonoperative modes (serial abdominal examination with/without computed axial tomography [CAT] and diagnostic peritoneal lavage) in determining the need for therapeutic laparotomy (TL) after anterior abdominal stab wound (ASW).

Methods: Retrospective review of ASW patients. Patients were divided into group A (DL/exploratory laparotomy) to identify peritoneal violation (PV) and group B (initial nonoperative modes).

The purpose of this study is to evaluate the treatment of patients with acute diverticulitis in the inpatient setting using minimal intervention. This was a retrospective study of 75 patients admitted over a 3-year period with acute diverticulitis as evidenced by computed tomography (CT) and clinical scenario. Of the patients enrolled, 24 (32%) had abscesses identified on their initial CT scan.

It is not clear why the N-terminal autoantigenic determinant of myelin basic protein (MBP), Ac1-9, is dominant in the B1O.PL (H-2(u)) mouse, given its weak I-A(u)-MHC binding affinity. Similarly, how do high-affinity T cells specific for this determinant avoid negative selection? Because the MBP:1-9 sequence is embryonically expressed uniquely in the context of Golli-MBP, determinants were sought within the contiguous N-terminal "Golli" region that could out-compete MBP:1-9 for MHC binding, and thereby prevent negative selection of the public response to Ac1-9, shown here to be comprised of a V beta 8.
