Venous system mapping of the digits and the hand: An anatomical study and potential surgical applications.

Background: Venous anatomy of the digits and the hand is poorly reported in the literature compared to arterial anatomy. While knowledge of the venous anatomy is crucial to ensure safe skin incisions, skin flap design, or blood return restoration for digital replantations, data in anatomical and clinical textbooks are rather limited. The purpose of this anatomical study was to describe the venous anatomy of the digits and the hand.

Face transplantation: A longitudinal histological study focusing on chronic active and mucosal rejection in a series with long-term follow-up.

The 2007 Banff working classification of skin-containing Tissue Allograft Pathology addressed only acute T cell-mediated rejection in skin. We report the longitudinal long-term histological follow-up of six face transplant recipients, focusing on chronic and mucosal rejection. We identified three patterns suggestive of chronic rejection (lichen planus-like, vitiligo-like and scleroderma-like).

Descriptive anatomy of the inferior epigastric, subscapular and internal thoracic vascular pedicles in three domestic mammals: A comparative study.

The descriptive anatomy of the inferior epigastric, subscapular and internal thoracic vascular pedicles of domestic animals is not fully known. Improvement of our knowledge in this field could lead to better development of animal models for both pedagogical purposes and surgical experimentation. The objective of this comparative study was to describe the descriptive anatomy of the inferior epigastric, subscapular and internal thoracic pedicles in three domestic mammals commonly used as animal models for experimentation.

Use of fluorescence to guide surgical resection in vulvo-vaginal neoplasia: Two case reports.

We report hereby two cases of fluorescence-guided surgical resection with Indocyanine green in vulvo-vaginal neoplasia. The first case was a 86-year old patient who had a high-grade squamous intraepithelial lesion of the left small lip and on the vulvar fork. After a first incomplete surgery, a second fluorescence-guided vulvectomy was performed with ICG injected intravenously to determine intraoperatively surgical margins.

Predictive factors of success at the French National Ranking Examination (NRE): a retrospective study of the student performance from a French medical school.

Background: The national ranking examination (NRE) marks the end of the second cycle (6th university year) of French medical studies and ranks students allowing them to choose their specialty and city of residency. We studied the potential predictive factors of success at the 2015 NRE by students attending a French School of Medicine.

Methods: From March 2016 to March 2017, a retrospective study of factors associated with the 2015 NRE success was conducted and enrolled 242 students who attended their sixth year at the school of medicine of Reims.

Omental flap for treatment of spondylodiscitis with lumbosacral dehiscence: A case report.

We report a case of pedicled omental flap use together with osteosynthesis treatment of a chronic L4-L5 spondylodiscitis due to a large sacral eschar. The 43-years-old patient was paraplegic and had depleted regional flaps solutions due to multiple previous surgeries. The procedure was carried out in supine position then in prone position whereby the dissected flap was recovered through the spine.

Beneficial role of adipose-derived mesenchymal stem cells from microfragmented fat in a murine model of duchenne muscular dystrophy.

Introduction: No etiologic therapy is available for Duchenne muscular dystrophy (DMD), but mesenchymal stem cells were shown to be effective in preclinical models of DMD. The objective of this study is to investigate the effect of microfragmented fat extracted on a murine model of DMD.

Methods: Fat tissue was extracted from healthy human participants and injected IM into DMD mice.

Psychological and psychiatric aspects of face transplantation: Lessons learned from the long-term follow-up of six patients.

Since 2005, at least 38 face transplantations have been performed worldwide. Available recommendations on psychological management are based on isolated cases or small case series, either not focused on mental health or with a short follow-up. We propose herein a clinical commentary on psychological and psychiatric outcomes from the follow-up of a prospective single-center cohort of six patients over a period of 3.

EZH1/2 function mostly within canonical PRC2 and exhibit proliferation-dependent redundancy that shapes mutational signatures in cancer.

Genetic mutations affecting chromatin modifiers are widespread in cancers. In malignant peripheral nerve sheath tumors (MPNSTs), Polycomb repressive complex 2 (PRC2), which plays a crucial role in gene silencing, is inactivated through recurrent mutations in core subunits embryonic ectoderm development (EED) and suppressor of zeste 12 homolog (SUZ12), but mutations in PRC2's main catalytic subunit enhancer of zeste homolog 2 (EZH2) have never been found. This is in contrast to myeloid and lymphoid malignancies, which harbor frequent loss-of-function mutations in EZH2.

Anatomical variations of the subscapular pedicle and its terminal branches: an anatomical study and a reappraisal in the light of current surgical approaches.

Purpose: While anatomical variations of the subscapular vessels are frequently encountered during axillary dissection, little is found in the literature. The aim of this cadaveric study was to define arterial and venous anatomical variations and frequencies of the subscapular vascular pedicle and its terminal/afferent vessels in women.

Methods: We performed 80 dissections of the axillary region on forty female formalin-embalmed cadavers.

Micro-fragmented fat injection reduces sepsis-induced acute inflammatory response in a mouse model.

Background: Severe sepsis has a high mortality rate. There is increasing evidence that human mesenchymal stem cells possess immunomodulatory properties in sepsis, particularly those from adipose tissue. We hypothesised that micro-fragmented human fat, obtained with minimal alteration of the stromal vascular niche, attenuates the inflammatory response and improves outcome in a murine model of sepsis.

[Autologous breast reconstruction by deep inferior epigastric free flap: Classic and minimally invasive extraperitoneal approaches].

Perforator free flaps allow breast reconstructions « like with like » with skin and fat, excluding mammary gland, with a low morbidity. Those autologous reconstructions prevent material associated infections, capsular contracture and implant replacements, associated to breast reconstructions including implants. DIEP flap was described in 1994 to reduce the morbidity faced with TRAM flaps harvest.

[Clinical photography by smartphone in plastic surgery and protection of personal data: Development of a secured platform and application on 979 patients].

Background: The clinical photography in plastic and reconstructive surgery has known a numerical breakthrough. The storage of online data, massive means of analysis such as facial recognitions algorithms poses a serious issue when it comes to the protection of personal data. We will assess a platform's benefits in connection with the computerized medical record, which will allow keeping the photos filed and centralized in a smart and secure manner.

Secondary bladder exstrophy repair with a bilateral gracilis muscle flap in an adult female patient: Case report of an original procedure.

Classical bladder exstrophy (CBE), affecting 1 birth out of 30,000, is characterized by an evaginated bladder plate through a defect in the lower abdominal wall, multiple abdominal wall anomalies including a pubic bone arch dehiscence. Numerous approaches from childhood to adulthood are thus required, depending on the severity of the deformity, including the associated genital anomalies. We report the case of a 19-year-old woman with CBE with a history of three-failed primary closure.

Medium- and Large-Sized Autologous Breast Reconstruction using a Fleur-de-lys Profunda Femoris Artery Perforator Flap Design: A Report Comparing Results with the Horizontal Profunda Femoris Artery Perforator Flap.

Background:  The volume of the profunda femoris artery perforator (PAP) flap limits its indications to small- and medium-sized breast reconstructions after modified radical mastectomy for cancer. We report a modified PAP flap design, including not only a vertical extension that increases its volume but also the skin surface, which suits larger breasts requiring immediate or delayed breast reconstructions and compare the results with our horizontal skin paddle PAP flap experience.

Patients And Methods:  In our center between November 2014 and November 2016, 51 consecutive patients underwent a PAP flap breast reconstruction following breast cancer.

Atypical Distant Metastasis of Breast Malignant Phyllodes Tumors: A Case Report and Literature Review.

Malignant phyllodes tumors (MPT) are rare breast neoplasms. Preoperative diagnosis is often challenging due to the unspecific clinical, radiological, and histological characteristics of the tumor. Dissemination pathways are local with chest wall invasion, regional with lymph nodes metastasis, and distant, hematogenous, mostly to the lungs, bones, and brain.

[Transposition of the cephalic vein in free flap breast reconstruction: Technical note].

Free flaps have become a reliable practice for breast reconstruction. However, the venous congestion is still the most frequent reason of flap failure. It is due to bad quality of the internal mammary veins, a preferential superficial venous outflow of the flap or due to venous thrombosis.

Minimally Invasive Laparoscopically Dissected Deep Inferior Epigastric Artery Perforator Flap: An Anatomical Feasibility Study and a First Clinical Case.

The deep inferior epigastric perforator (DIEP) flap is a workhorse of breast reconstruction. Risks of herniation derive from violation of the rectus abdominis muscle anterior rectus sheath and might be reduced by minimally invasive laparoscopic dissection ("MILD") of the deep inferior epigastric vessels. The authors performed a feasibility study on five anatomical subjects and performed a secondary right breast reconstruction on a 67-year-old woman.
