A canalicular laceration is the most common injury of the lacrimal drainage system and can result from direct or indirect injury to the canalicular system. If the wounds are not managed properly, they can lead to scarring, stenosis, and inflammation, which may lead to symptomatic epiphora. We successfully reconstructed canalicular lacerations using Mini-Monoka tubes (FCI Ophthalmics, Marshfield Hills, MA) under microscopic magnification. ⋯ No complications related to the Mini-Monoka tube, such as punctual plug migration, eye irritation, inflammation, granuloma formation, or erosion, occurred during the follow-up period. The goal of reconstructing a lacerated canaliculus is accurate approximation of the injured end of the canaliculus to facilitate mucosal healing and to prevent a canalicular obstruction. We believe that microscopic canalicular reconstruction with a Mini-Monoka tube is a safe, reliable, and straightforward method with fewer complications and is more effective for preventing iatrogenic injury in the unaffected canaliculus and minimizing patient discomfort.

Regenerative medicine is an emerging and rapidly evolving field of research and therapy, thanks to new discoveries on stem cells. Adipose tissue is a connective tissue which contains a reserve of mesenchymal stem cells. Clinical improvements in trophic characteristics of teguments after autologous fat graft are well described in literature. In this paper, we present our observation after 6 years of autologous fat graft experience in scar remodeling. ⋯ Injection of processed autologous fat seems to be a promising and effective therapeutic approach for scars with different origin such as burns and other trauma scars, and post-surgery and radiotherapy outcomes. In general, we can affirm that treated areas regain characteristics similar to normal skin, which are clinically objectivable, leading not only to aesthetic but also functional results.

Randomized Controlled Trial Comparative Study
Study comparing midazolam and nitrous oxide in dental anxiety control.
The purpose of this study is to comparatively assess the effect of midazolam and nitrous oxide associated with oxygen, in lower third molar extractions, on the change in the anxiety level of patients by salivary cortisol dosage. Twenty-eight male patients underwent lower third molar extraction under sedation with midazolam and nitrous oxide. ⋯ By salivary cortisol, 40 minutes after midazolam administration, there has been a statistically significant difference compared with the mean baseline value. Midazolam was the most effective sedation method for reducing salivary cortisol level.

The objective of this study was to establish the culture method of human bone marrow mesenchymal stem cells (BMSCs) from alveolar bone marrow. ⋯ The cells of the marrow complex obtained by low-speed method in implant site preparation cultured in vitro were identified as BMSCs through the morphological observation and the flow cytometry. It is a kind of feasible and simple culture method of human primary BMSCs.

There is no more important decision an academic Plastic Surgery Department or Division can make than naming a chair or chief. Externally recruited leadership brings fresh perspectives and connections. Critics, however, argue that they lack the in-depth knowledge of the institution's culture and history that may be needed to succeed. The ability and skill of an internal candidate is already known and can increase the odds of that person's success in the leadership position. Finally, external recruitment can be a more costly process. Ultimately, the decision is really a litmus test for a Plastic Surgery program. The authors aim to evaluate factors influencing ascent in Plastic Surgery leadership, including training history, internal promotion, and external recruiting. ⋯ Many factors influence the decision to recruit leadership from internally or to hire an external candidate. These include the time to fill the position, program culture, candidate experience, and cost. These results support that the insider/outsider hire decision is ultimately one of duality. That dichotomy is achieved with an emphasis on internal promotion, but always with an eye towards the advantages of bringing in external talent as a valuable contribution to increase organizational success.
