Autophagy drives fibroblast senescence through MTORC2 regulation.

Sustained macroautophagy/autophagy favors the differentiation of fibroblasts into myofibroblasts. Cellular senescence, another means of responding to long-term cellular stress, has also been linked to myofibroblast differentiation and fibrosis. Here, we evaluate the relationship between senescence and myofibroblast differentiation in the context of sustained autophagy.

Delaying implant-based mammary reconstruction after radiotherapy does not decrease capsular contracture: An in vitro study.

The most common complications of irradiated implant-based mammary reconstruction are fibrosis and capsular contracture. The indications for postmastectomy adjuvant radiotherapy have considerably broadened. Facing an increased number of patients who will require radiotherapy, most guidelines recommend delaying reconstruction after radiotherapy to prevent long-term fibrotic complications.

The double capsules in macro-textured breast implants.

Breast implants are amongst the most widely used types of permanent implants in modern medicine and have both aesthetic and reconstructive applications with excellent biocompatibility. The double capsule is a complication associated with textured prostheses that leads to implant displacement; however, its etiology has yet to be elucidated. In this study, 10 double capsules were sampled from breast expander implants for in-depth analysis; histologically, the inner capsular layer demonstrated highly organized collagen in sheets with delamination of fibers.

Super-drained distally based neurofasciocutaneous sural flap: a case series and review of literature.

Objective: The distally based neurofasciocutaneous sural flap is central to the armamentarium for the reconstruction of leg's distal third, ankle, and hindfoot. Despite the use of adapted techniques aimed at increasing the flap's reliability, venous congestion remains a frequently encountered problem. We present a venous super-drainage technique used by the senior author to reduce venous congestion and improve flap reliability when harvesting larger flaps.

Replantation vs revision amputation in single digit zone II amputations.

The objective of this study was to compare the functional outcomes of zone II amputations treated with either replantation or revision amputation at our institution to better aid patients in their decision making process regarding these treatment options. We conducted a comparative retrospective study. All cases of single digit amputations received at our replantation center between 2007 and 2011 were screened for single digit zone II injuries.

["The ambulatory surgery of breast reduction: The adaptation to a North-American practice"].

Objective: After the recent publication of the prospective study of feasibility of mammary reduction in ambulatory setting by Guilbert et al., we would like to present our North-American experience and share some data from the last year.

Methods: We obtained four data from our medical archives: the total number of reduction mammaplasties done during the last year, the number of cases done in ambulatory setting, the number of cases done with hospitalization, and the number of conversions (ambulatory cases transformed into hospitalizations lasting more than 24 hours)

Results: Two hundred and eighteen bilateral mammary reductions were completed between March 2011 and April 2012.
