Successful breastfeeding after breast reduction surgery or mastopexy: A retrospective comparative study.

Breastfeeding has been widely encouraged by health care systems for many years. Breast reduction or mastopexy, are very frequent procedures often performed on young women. The main objective of this study is to evaluate the impact of breast surgery on breastfeeding by comparing the success rate of breastfeeding in operated women versus unoperated women. Secondary objectives are to evaluate the breastfeeding success rate according to the surgical technique or the weight resected. A retrospective comparative study was conducted. Women of childbearing age who underwent breast reduction surgery or mastopexy at Henri-Mondor Hospital were contacted to answer a questionnaire about their pregnancies. Two hundred nine patients answered and two groups of patients were constituted, a preoperative group of 104 women who had a pregnancy before surgery and a postoperative group formed by 61 women who had a pregnancy after surgery. Breastfeeding success rate was 82% in the preoperative group versus 41% in the postoperative group. A statistically significant difference was found on the success rate of breastfeeding, as well as the rate of exclusive breastfeeding, with significantly lower rates in the postoperative group. In contrast, there was no significant difference between the different pedicles used, neither according to the weight of the resected gland. The cause of failure in the postoperative group was in most cases insufficient milk. Breast reduction surgery or mastopexy seems to have negative impact on the ability of operated women to breastfeed. This impact is multifactorial so these results should be interpreted with caution and further studies are needed to improve the management of these patients.

Assessment of the Efficacy of Cryolipolysis on Abdominal Fat Deposits: A Prospective Study.

BACKGROUND: Cryolipolysis is a non-invasive and efficacious procedure for body contouring. The effectiveness of cryolipolysis has been demonstrated on multiple areas of the body, but on a limited number of subjects. The aim of this study is to demonstrate the effectiveness and the safety of cryolipolysis in the lower abdomen adipose tissue thickness reduction. METHODS: A prospective study on 60 healthy women was carried out using CryoSlim Hybrid device. Each patient underwent two cryolipolysis sessions centered on the abdominal area. The primary endpoint was to decrease the thickness of the abdominal fat deposits. The change in the abdominal circumference and the thickness of the subcutaneous fat layer were assessed. Patient satisfaction and tolerance of the procedure were also taken into account. RESULTS: A significant reduction of the abdominal circumference and subcutaneous fat layer thickness was observed. The mean decrease in abdominal circumference was 2.10 cm (3.1%) 3 months after the procedure and 4.03 cm (5.8%) 6 months after the procedure. The mean decrease in fat layer thickness was 1.25 cm (43.81%) 3 months after the procedure and 1.61 cm (41.73%) 6 months after the procedure. No major adverse events were noted. All patients were very satisfied, and minimal pain was reported. CONCLUSIONS: Cryolipolysis is an effective technique to treat abdominal localized fat deposits. No major adverse events have been described for this procedure. Our promising results should encourage further studies aimed at optimizing the efficacy of the procedure without a considerable increase in the risks.

Clitoral Reconstructive Surgery After Female Genital Mutilation/Cutting: Anatomy, Technical Innovations and Updates of the Initial Technique.

INTRODUCTION: Female genital mutilation (FGM) includes all procedures that involve partial or total removal of the female external genitalia or any other injury of the female genitalia that is performed for nonmedical reasons. FGM is classified into 4 types. Surgical clitoral reconstruction was first described by Thabet and Thabet in Egypt and subsequently by Foldès in France. The technique was then modified by different authors. AIM: This article aims to provide a detailed description of clitoral surgical reconstruction and the modifications which have been made over time to improve the procedure while recalling current knowledge in the anatomy of the clitoris. METHODS: We performed a broad systematic search in PubMed/Medline and EMBASE bibliographic databases for studies that report the surgical technique of clitoral reconstruction. From the anatomical point of view, we examined available evidence (from 1950 until 2020) related to clitoral anatomy, the clitoral role in sexual functioning, female genital mutilation/cutting, and surgical implications for the clitoris. MAIN OUTCOMES: A review of the surgical techniques for clitoral reconstruction after female genital mutilation/cutting RESULTS: We described the current anatomical knowledge about the clitoris, and the procedures based on the surgical technique by Pierre Foldès, We included the technical modifications and contributions described in articles published subsequently. CONCLUSION: Surgical repair of the clitoris for FGM offers anatomical and functional results although they still have to be evaluated. However, it should not be the only therapeutic solution offered to women with FGM. Botter C, Sawan D, SidAhmed-Mezi M, et al.

Hymen Restoration: An Experience From a Moroccan Center.

BACKGROUND: Hymenoplasty is one of the least described vulvovaginal procedures in plastic surgery without any surgical standard that attempts to restore the hymen's ability to bleed during sexual intercourse on a couple's wedding night. OBJECTIVES: The objective of this study was to report outcomes from a Moroccan retrospective study of a series of 529 patients who underwent either a hymenorrhaphy or a hymenoplasty. METHODS: This was a retrospective study of 529 patients who underwent hymen restoration at a center in Morocco between April 2010 and April 2019. The data were collected according to the requirements of the center through preoperative and postoperative consultations and in-person or phone post-coital interviews. The procedure consisted of suturing the edges of the hymen remnants with Vicryl 5-0, leaving a small opening in the newly reconstructed hymen. Two techniques-hymenal flap hymenoplasty and vaginal flap hymenoplasty-were employed depending on the presence or absence of hymen remnants. RESULTS: A total of 529 patients underwent hymen restoration, including 42% hymenorrhaphies, 58% hymenoplasties, 39% hymenal flap hymenoplasty, and 19% vaginal flap hymenoplasty. The mean age of the patients was 32 years. Of the 227 women who underwent a hymenorrhaphy, no failure was reported, and all the patients who had sexual intercourse within 15 days of the procedure experienced vaginal bleeding. Of the 99 hymenoplasties employing vaginal flaps, only 1 failure was reported. CONCLUSIONS: The techniques utilized in our cohort are safe and the complications are minor with general satisfaction of patients.

Microfat and Nanofat Grafting in Genital Rejuvenation.

BACKGROUND: Genitourinary syndrome of menopause (GSM) is a major problem in many post- or perimenopausal women. Lipofilling has long been considered to be an effective technique for restoring volume, but the discovery of its trophic proprieties has made it the most widely utilized method in regenerative medicine. OBJECTIVES: The authors aimed to assess the safety and efficacy of microfat and nanofat grafting for vulvovaginal rejuvenation. METHODS: Women with GSM who met the inclusion criteria were enrolled. Women received microfat in the labia majora and nanofat in the vagina; follow-up was conducted 1, 3, 6, 12, and 18 months. The vaginal health index (VHI) and Female Sexual Distress (FSD) were utilized to assess improvement in vulvovaginal atrophy, orgasm, and sexual desire posttreatment. RESULTS: Fifty women were included; their average age was 53 years (range, 45-63 years). The VHI score significantly increased at 1 and 3 months after treatment (P < 0.0001). Moreover, the average FSD score showed a significant improvement at 1 and 3 months posttreatment. This score stabilized from 6 to 12 months but showed further improvement at 18 months. At 6 months posttreatment, for both scales, data pertaining to 80% of patients appeared normalized. There was a particular benefit noted for dryness and dyspareunia. At 18 months, the results remained stable for all of patients. No major side effects were observed. CONCLUSIONS: There are now many ways to rejuvenate the intimate sphere, but microfat and nanofat grafting seem to offer good results with an autologous procedure. Their utilization appears promising for genital rejuvenation.

Synergistic Effects of Autologous Platelet-Rich Plasma and Hyaluronic Acid Injections on Facial Skin Rejuvenation.

BACKGROUND: Many therapeutic options are currently available for facial skin rejuvenation, but little evidence exists about the efficacy of combining such procedures. OBJECTIVES: The aim of this study was to assess and investigate the synergistic effect of hyaluronic acid (HA) and autologous platelet-rich plasma (a-PRP) injections on facial skin rejuvenation. METHODS: For this randomized controlled prospective study, 93 eligible patients were enrolled and randomized into 3 intervention groups to undergo a series of 3 treatment sessions with either a-PRP, HA, or a mixture of a-PRP and HA (Cellular Matrix; Regen Lab) injected into facial cheeks. RESULTS: A total of 93 patients were included. Treatment with Cellular Matrix led to a very significant improvement in the overall facial appearance compared with treatment with a-PRP or HA alone (P < 0.0001). Participants treated with Cellular Matrix showed a 20%, 24%, and 17% increase in FACE-Q score at 1, 3, and 6 months posttreatment, respectively. For the HA group, the improvement in FACE-Q score was 12%, 11%, and 6% at 1, 3, and 6 months posttreatment, respectively, whereas for the a-PRP group the improvement was 9%, 11%, and 8% at 1, 3, and 6 months posttreatment, respectively. Biophysical measurements showed significantly improved skin elasticity for the Cellular Matrix group compared with the groups receiving a-PRP or HA alone. No serious adverse events were reported. CONCLUSIONS: Combining a-PRP and HA seems to be a promising treatment for facial rejuvenation with a highly significant improvement in facial appearance and skin elasticity compared with a-PRP or HA alone.

Postoperative Complications and Patient Satisfaction After Abdominal Etching: Prospective Case Series of 25 Patients.

INTRODUCTION: Conventional liposuction has provided good outcome for years. Abdominal etching (or abdominal high definition liposuction) allows the surgeon to shape and enhance the abdominal muscles by removing specific grooves of subcutaneous fat. The aim of this study is to describe the technique and the complications and to assess patients' satisfaction rate. MATERIALS AND METHODS: Between January 2015 and January 2017, 25 patients (21 men and 4 women) underwent abdominal etching procedures in our department. The authors describe the technique and the specific key points of the procedure. All patients were seen at day 5, 10, 30, and 180. At day 180, everyone answered a modified Likert scale survey relating to their satisfaction. RESULTS: No hematoma, infection, or seroma was reported. One patient experienced a superficial pressure wound caused by an improper positioning of the final dressing. Almost all patients (96%) were happy or very happy with the overall outcome of their abdominal etching. CONCLUSION: The number of requests for abdominal liposculpture should increase in the coming years, and plastic surgeons specialized in silhouette surgery should be able to master this technique in order to add it to their therapeutic arsenal.

Clinical benefit of using a multifractional Er:YAG laser combined with a spatially modulated ablative (SMA) module for the treatment of striae distensae: A prospective pilot study in 20 patients.

BACKGROUND AND OBJECTIVE: Striae distensae (SD) are cutaneous lesions that often occur on the breasts, abdomen, hips, and thighs. The aim of this study is to evaluate the effectiveness of a new technique using a non-invasive Er:YAG laser combined with Spatially Modulated Ablation (SMA) module for the treatment of SD. STUDY DESIGN/MATERIALS AND METHODS: This prospective pilot clinical study included 20 patients with skin phototypes I to IV who are affected by SD. The Er:YAG 2940 nm laser with SMA module was used in scanning mode with fluences of 2.3 J/cm2 , frequency of 3 Hz, and pulse duration of 0.3 milliseconds. The laser beam is split into several microspots and penetrates only by 50 µm in the epidermis thickness. This technology induces also the generation of acoustic waves to stimulate tissue regeneration. Each patient underwent six laser sessions. An objective and subjective assessment of SD were used. All adverse events were reported. RESULTS: Most patients reported good improvement and expressed their satisfaction with the treatment. Cutometric analysis showed significant improvement in skin elasticity at the end of study. Moreover, ultrasound analysis revealed an increase in dermal thickness (P < 0.01). POSAS scores decreased significantly at 3 and 6 months, reflecting improved skin quality. The average recovery time was 5 days, with no adverse effects reported. CONCLUSION: Using Er:YAG laser (2,940 nm) with SMA technology to treat SD resulted in improved volume and textural appearance without side effects. The elasticity and thickness of the dermis also improved. The Er:YAG laser with SMA module may be considered as a novel and effective technique to treat SD lesions with minimal time recovery.

The Outcomes Assessment of the Plasma Blade Technology in Upper Blepharoplasties: A Prospective Study on a Series of 25 Patients.

BACKGROUND: The Dermo Ablation Surgery (DAS) Medical® (Technolux, Italy) device is a plasma blade which induces a plasma voltaic arc causing a retraction in the epidermis and superficial dermis. OBJECTIVE: The aim of our study is to prove the efficacy and safety of the DAS Medical® device in dermatochalasis size reduction. METHODS: Our prospective study included 25 adult patients presenting with upper eyelid dermatochalasis undergoing a two-session treatment protocol with the DAS Medical® device (with a month treatment-free interval). The primary end point was the reduction in the size of the dermatochalasis. The secondary end points were patient satisfaction, and a blinded assessment of the outcomes was carried out by 15 plastic surgery specialists on post-procedural pictures. RESULTS: The mean reduction in the size of the dermatochalasis was estimated at 2.47 mm on a 6-month follow-up (13.5 mm at T0 vs. 11.03 mm at 6 months, p = 0.0002) and 1.97 mm on a 12-month follow-up ((13.5 mm at T0 vs. 11.53 mm at 12 months, p = 0.0055). Eighty per cent of the patients and 78% of the assessing clinicians were globally satisfied with the results on a 12-month follow-up. The mean visual analogue pain score reported during the treatment was 4.5/10; MEOPA® was used in 23% of cases. No irreversible post-procedural sequelae (complications) were observed. CONCLUSION: Voltaic plasma arc treatment with DAS Medical® is an effective technique for non-invasive blepharoplasty on moderate dermatochalasis patients not suffering from palpebral lipoptosis and is very well tolerated. It can be usefully and successfully associated with surgery. LEVEL OF EVIDENCE IV: This journal requires that authors assign a level of evidence to each article.

High-Intensity Focused Ultrasound: A Satisfactory Noninvasive Procedure for Neck Rejuvenation.

BACKGROUND: High-intensity focused ultrasound (HIFU) is an advanced technology that has been developed in response to the growing demand for noninvasive face rejuvenation. OBJECTIVES: The aim of this study was to evaluate the rejuvenation effects, patient satisfaction, and safety of HIFU treatment of the neck in a European population. METHODS: This was a prospective study of 20 patients. The patients were treated with HIFU, and the outcomes were investigated. The modified FACE-Objective Assessment Scale, developed by our team, and the subjective Investigator Global Improvement Assessment Scale (IGIAS; -1 to 3) were used to judge the results of HIFU. Five blinded evaluators scored the procedure outcomes based on photographs taken before and 6 months after the procedure. Side effects were reported and pain was evaluated on a visual analog scale of 0 to 10. RESULTS: Clinical results, such as better definition of the cervicomental angle, were observed in the treated areas. The pretreatment and posttreatment evaluation scores for double chin and skin laxity were evaluated by 4 of 5 evaluators as significantly improved. The IGIAS score was between 1 and 5 in 2 patients, between 6 and 10 in 7 patients, and between 11 and 15 in 11 patients. No patients had a score between -5 and 0. No major complications were reported. The mean pain scores for the D4, M7, and S7 transducer treatments were 5.6 (range, 4.5-6.7), 4.2 (range, 2.5-5.9), and 2.05 (range, 1.05-3.05), respectively. CONCLUSIONS: HIFU may be considered a satisfactory, simple, reproducible, rapid, and safe procedure for neck rejuvenation.Level of Evidence: 4.

Labia Majora Augmentation Combined With Minimal Labia Minora Resection: A Safe and Global Approach to the External Female Genitalia.

BACKGROUND: All the labia minora reduction techniques fail to treat the other component of the abnormally increased labia minora to majora ratio: the labia majora atrophy. The purpose of this study is to describe a technique of female genitalia beautification, which combines labia majora augmentation and conservative labia minora reduction. METHODS: The hypertrophied labia minora were first treated by a conservative inferior wedge excision with a superior flap. The conservative excision was done to obtain labia minora that would still protrude beyond the labia majora because it will be masked by the augmentation of the labia majora. Labia majora augmentation was done by autologous fat transplantation. The newly augmented labia majora completely masked the conservatively reduced labia minora. RESULTS: Twenty-one patients underwent surgery for labia majora augmentation and labia minora reduction. One patient (4.7%) had a small separation of the labial edge postoperatively that resolved with no additional interventions. There was no flap necrosis or infections. No patient reported pain or sexual dysfunction. Seventeen patients (81%) were satisfied or very satisfied with their results. CONCLUSIONS: Labia majora augmentation combined with a conservative labia minora reduction is an appealing procedure because it enhances the global aspect of the female genitalia while reducing the labioplasty complications.

Efficacy of Autologous Platelet Concentrates as Adjuvant Therapy to Surgical Excision in the Treatment of Keloid Scars Refractory to Conventional Treatments: A Pilot Prospective Study.

BACKGROUND: After conventional treatments, keloid scars show varying degrees of recurrence. The aim of this study was to assess the efficacy and safety of platelet-rich plasma in the treatment of postoperative keloid scars refractory to conventional treatments. METHODS: This pilot prospective study was conducted in 17 patients with keloid scars who did not respond to 4 injections of cortisone or radiotherapy after extralesional resection of keloid. Platelet-rich plasma was injected intraoperatively and then 3 times with a 1-month interval. The primary end point was the complete remission of keloid scars 2 years posttreatment. Scar pruritus severity was scored before and after treatment. The study protocol was approved by the ethics committee and authorized by the French National Agency. This trial was registered at ClinicalTrials.gov, identifier NCT02922972. RESULTS: Nine keloid scars (53%) were completely resolved at 2 years, and 5 (29%) completely relapsed after treatment. Pruritus severity score was significantly lower at 2 years compared with baseline (1.33 ± 0.97 before treatment and 0.40 ± 0.63 at 2 years, P < 0.003). The mean Vancouver Scar Scale score significantly improved (8.18 ± 2.38 before treatment and 3.82 ± 1.98 at 2 years, P < 0.001). CONCLUSIONS: Injecting platelet-rich plasma is an effective and safe method as adjunctive therapy to resection for treating keloid scars refractory to conventional therapy.

Multifractional microablative laser combined with spacially modulated ablative (SMA) technology for facial skin rejuvenation.

BACKGROUND AND OBJECTIVE: Due to the increasing demand for aesthetic procedures, especially facial aesthetic surgery, a new laser technology has been developed for facial skin rejuvenation and wrinkle treatment. The aim of this study was to objectively and subjectively assess the clinical efficacy and safety of Erbium:YAG laser combined with Spatially Modulated Ablation (Er:YAG + SMA) on facial skin rejuvenation. STUDY DESIGN/MATERIALS AND METHODS: Patients with Fitzpatrick skin type's I-IV were prospectively included. Inclusion criteria consisted of having wrinkles and irregular skin texture. All patients underwent two Er:YAG + SMA sessions (1 month apart) to stimulate tissue regeneration. Er:YAG laser emits wavelength at 2,940 nm and when combined with SMA, a resonance effect is produced in the dermis to promote tissue regeneration. Facial skin elasticity and firmness were objectively assessed by Cutometer at baseline and month 6 (M6). Aesthetic improvement was qualitatively assessed using digital photographs. Patient satisfaction with regard to their facial appearance was self-assessed using the validated FACE-Q scale and the patient-perceived age VAS scale at baseline, M1, and M6. Side effects were investigated after each session. RESULTS: Thirty-four patients were included, 50% (18 patients) had Fitzpatrick skin type III and 41% (14 patients) were smokers. Skin elasticity indices were significantly improved: from 0.335 ± 0.015 at baseline to 0.387 ± 0.021 at M6 (P = 0.05*) for R5 (net elasticity). Skin firmness was assessed through R7 (biological elasticity) and R6 (viscoelastic ratio) at baseline and M6: a significant increase from 0.235 ± 0.01 to 0.2709 ± 0.009 (P < 0.03**) and decrease from 0.486 ± 0.022 to 0.3918 ± 0.023 (P < 0.006***) were respectively observed. A negative value for R6 corresponded to an improved skin condition. The FACE-Q scores were significantly increased from 39.4 ± 6.7 at baseline to 45.4 ± 9.1 at M1 (P < 0.006***) and 50.4 ± 9.8 at M6 (P < 0.0001***), reflecting wrinkle reduction and enhanced rejuvenation. According to the age appraisal VAS scale, results showed that patients felt younger by -2.92 years at M1 (P < 0.0001***) and -4.13 years (P < 0.0001***) at M6. No adverse reaction was reported. CONCLUSION: The Er:YAG + SMA technology offers an effective and safe treatment alternative for facial skin rejuvenation. It reduces the recovery time compared to conventional lasers such as carbon dioxide laser. Lasers Surg. Med. 49:78-83, 2017. © 2016 Wiley Periodicals, Inc.

Autologous Platelet-Rich Plasma/Thrombin Gel Combined with Split-Thickness Skin Graft to Manage Postinfectious Skin Defects: A Randomized Controlled Study.

BACKGROUND: Managing cutaneous substance loss after debridement is challenging, especially if it is secondary to necrotizing soft tissue infection, such as necrotizing fasciitis and Fournier gangrene. After skin graft reconstruction, the healing process is longer and may be difficult, depending on the wound site, skin defect size, and patient comorbidities. OBJECTIVE: The aim of this study was to investigate whether autologous platelet-rich plasma (A-PRP) could accelerate and improve wound healing after cutaneous reconstruction for tissue loss secondary to soft tissue infection. METHODS AND MATERIALS: A prospective, controlled, randomized, open-label study was conducted. Patients (N = 27) were randomized into 2 groups by drawing lots using sealed envelopes: an experimental (n = 14) and a control group (n = 13). Initially, all the necrotic tissue was extensively debrided and excised. In the experimental group, patients underwent a split-thickness skin graft (STSG) combined with A-PRP/thrombin gel sprayed on the wound bed and on the STSG after staple fixation. In the control group, patients underwent an STSG alone. RESULTS: Results showed that the mean complete healing time was significantly reduced (by almost 50%) when A-PRP/thrombin gel was combined with an STSG compared with STSG alone (37.9 [SD, 14.3] days in the experimental group vs 73.7 [SD, 50.84] days in the control group, P = .01). No patient experienced complications during the follow-up period. CONCLUSION: The combination of A-PRP/thrombin gel and an STSG significantly improved clinical outcomes and shortened the wound healing time. Therefore, this treatment combination could provide a way to heal skin after a necrotizing soft tissue infection with minimal recovery time.

A Prospective, Comparative Study (before and after) for the Evaluation of Cryothermogenesis' Efficacy in Body Contouring: Abdomen and Saddlebags.

BACKGROUND: Cryolipolysis is a noninvasive method that allows selective reduction of adipose tissue. The aim of the present study was to evaluate the efficacy of cryothermogenesis, the repetitive applications of cryotherapy, in body contouring of the abdomen and saddlebag areas. METHODS: Thirty participants were included in the study. Premenopausal women with an overload of subcutaneous abdominal and saddlebag adipose tissue were enrolled. For each participant, five cryothermogenesis sessions were carried out using a medical device equipped with two cooling probes. The primary endpoint was metric measurement. The secondary endpoints were the measurement of subcutaneous fat mass using a Lunar iDXA whole-body scanner (GE Healthcare, Madison, Wis.) and a metabolic assessment conducted before treatment and 15 days after treatment. RESULTS: The mean age of participants was 36.72 ± 7 years. Participants had different phototypes and an average body mass index of 23.0 ± 1.41 kg/m2. A decrease in body mass index was observed 3 months after the last session; the body mass index dropped to 20.5 ± 2.1 kg/m2 (p = 0.004 compared to baseline). Waist measurements showed a significant decrease, with an average loss of 4.1 cm after 15 days and 4.62 cm after 3 months. Concerning the circumference of saddlebags, a decrease was observed 3 months after treatment. These results were confirmed by iDXA computed tomographic measurements, showing a significant fat mass reduction in the treated areas. CONCLUSION: The results indicate that subcutaneous fat in the abdomen and saddlebags was reduced after five successive cryothermogenesis sessions, without any complications, in a cohort of participants with different phototypes. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

New therapeutic targets to develop molecules active in drug-resistant epilepsies.

We have shown that the glycolytic enzyme glyceraldehyde-3-phosphate dehydrogenase (GAPDH) is the kinase involved in the endogenous phosphorylation of the alpha1 subunit of the gamma-aminobutyric acid (GABA)(A) receptor (GABA(A)R), maintaining GABA(A)-R function. GABA(A)R endogenous phosphorylation is opposed by one or several atypical phosphatases. We have shown in addition, using cerebral tissue obtained during epilepsy surgery and control tissue from patients undergoing brain tumor surgery, that both endogenous phosphorylation and GABA(A)R function are significantly reduced in the "epileptogenic" cerebral cortex when compared to control. This dysfunction likely contributes to seizure generation and/or transition from the interictal to the ictal state. The therapeutic challenge is to alleviate the endogenous phosphorylation deficiency of GABA(A)R in the epileptogenic cortical tissue, either through activating the endogenous kinase activity, or inhibiting dephosphorylation of the alpha1 subunit. Following the first trail, we have shown that spermine (the most effective polyamine) increases the GAPDH kinase activity on GABA(A)R and that subsequently such modulation potentiates its function as assessed by rundown studies on isolated neurons. Following the second trail, we have developed methods to identify these atypical membrane-bound phosphatases. Their activities were detected using two synthetic phosphopeptides corresponding to the alpha1 regions of phosphorylation by GAPDH. After purification, the active fractions are submitted to proteomic analysis by nanoLC-Maldi-TOF/TOF for protein identification. Two candidate proteins have been identified, which will be used as targets for high-throughput screening in order to develop original antiepileptic molecules.

Oncological and aesthetic outcome following surgical management of orbito-palpebral skin cancers: A retrospective study of 132 patients.

BACKGROUND: The incidence of facial skin cancers continues to rise, with major studies on their impacts still lacking in the literature. This study reports on the oncological and aesthetic results following surgical management of an orbito-palpebral skin cancer. METHODS: This retrospective, monocentric study included patients treated for a non-melanoma skin cancer of the eyelid and orbit. Risk factors, location, histological type, invaded or insufficient margins, healing time, surgical management by excision and direct closure, skin graft or local flaps, self-evaluated aesthetics, and quality of life results were all compared. RESULTS: The study included 132 patients operated for basal cell carcinoma (71.9%), squamous cell carcinoma (22.9%), or for another type (5.2%) between November 2011 and January 2017. Average tumor size was 9.6 ± 6.3 mm. Surgical management resulted in excision and open healing (9.1%), excision and direct closure (3.9%), skin graft (31.1%), local flap (21.9%), or another type of reconstruction (3.0%). Significant links between invaded or insufficient margins and basal cell type (OR = 3.37, p = 0.014), tumor size over 7 mm (OR = 2.7, p = 0.011), double location (OR = 8.44, p = 0.04), flap-based reconstruction (OR = 0.290, p = 0.02), and female gender (OR = 0.418, p = 0.034) were reported throughout our multivariate analysis. CONCLUSIONS: This study brings out consequential information on factors linked with invaded or insufficient excision margins. Larger cohorts should evaluate the aesthetic outcomes in such a population.

Should platelet-rich plasma be activated in fat grafts? An animal study.

BACKGROUND: The adjunction of platelet-rich plasma with graft fat has been the subject of a few clinical trials which have demonstrated its value in adipocyte survival. The aim of this study was to assess the different efficacies between activated and non-activated PRP on adipose cells in vitro and for adipose tissue graft survival in vivo. METHODS: The in vitro study assessed the effects of PRP on both the proliferation and adipocyte differentiation of adipose cells. For the in vivo study, 8 nude rats received 3 human fat injections as follows: 0.8 mL of fat + 0.2 mL of normal saline; 0.8 mL of fat + 0.2 mL of non-activated PRP; and 0.8 mL of fat + 0.2 mL of PRP activated with calcium chloride (CaCl2). The quantitative assessment of adipocyte survival was implemented after 3 months using histomorphometric analysis. Histological and immunohistochemical analysis were also performed to evaluate angiogenesis, inflammation and quality of adipocytes in the grafted tissue. RESULTS: We showed that activated PRP stimulated, in vitro, proliferation and differentiation of adipose cells. In vivo experiments indicated that CaCl2-activated PRP was more efficient than non-activated to prolong the survival of fat grafts in nude rats. The mean percentage areas occupied by viable adipocytes in the PRP-free group, non-activated PRP group and activated PRP group were 13%, 14% and 24% (p = 0.05%), respectively. Histological and immunohistochemical analysis revealed protective effect of activated PRP on inflammation and adipocyte death. CONCLUSION: This study showed that activation by CaCl2 improves the beneficial effects of PRP for fat graft maintenance.

Efficacy of injecting platelet concentrate combined with hyaluronic acid for the treatment of vulvovaginal atrophy in postmenopausal women with history of breast cancer: a phase 2 pilot study.

OBJECTIVE: Approximately 50% to 70% of breast cancer survivors are affected by one or more symptoms of vulvovaginal atrophy (VVA). For those who cannot take hormone therapy, autologous platelet-rich plasma combined with hyaluronic acid (A-PRP-HA) may provide a new alternative therapy for the treatment of VVA in postmenopausal women with history of breast cancer. METHODS: We enrolled 20 postmenopausal breast cancers survivors with VVA and a score of <15 on the Gloria Bachman Vaginal Health Index (VHI) comprised of five items including: vaginal pH, elasticity, fluid volume (secretions), epithelial integrity, and moisture.We administered intramucosal injections of A-PRP combined with HA (Regenkit) and performed clinical evaluations at 0, 1, 3, and 6 months. Primary endpoint: evaluation of vulvovaginal mucosa changes using the VHI; secondary endpoint: evaluation of dyspareunia and sexual dysfunction based on the Female Sexual Distress (FSD) score. RESULTS: All participants (20 women) showed improvement in the clinical symptoms of vaginal dryness and dyspareunia. The VHI score showed a significant increase at 6 months, going from a total baseline score (pretreatment) of 10.7 ±â€Š2.12 to 20.75 ±â€Š4.8 (P < 0.0001) at 6 months. Improvement in hydration and vaginal epithelial integrity was reported. A VHI score of > 15 showed a successful treatment outcome. The FSD score decreased significantly during the study, from a baseline score of 36.35 ±â€Š2.53 pretreatment to 30.15 ±â€Š2.47 6 months after treatment, representing improvement of 17% (P < 0.0001, respectively). No adverse events were reported. CONCLUSIONS: The injection of A-PRP-HA appeared to be a promising method to improve the trophicity and hydration of vaginal mucosa for the treatment of VVA in postmenopausal breast cancer survivors with contraindications to hormone therapy.
