IntroductionLa consommation régulière de cannabis peut s'associer à certaines toxicités endobuccales, souvent mal connues du clinicien : xérostomie, caries, maladie parodontale, leucoedème, hyperplasie gingivale, colonisation à Candida albicans, leucoplasie ou gingivite…ObservationNous rapportons ici l'apparition d'une coloration verte de la langue chez un patient, consécutive à l'inhalation intensive de marijuana.DiscussionCette complication n'a qu'exceptionnellement été rapportée dans la littérature médicale. Paradoxalement, elle est clairement identifiée sur différents moteurs de recherche sur internet, notamment Google.BackgroundRegular cannabis use may be associated with several oral changes not usually identified by dermatologists: xerostomia, increased risk of caries, periodontitis, leukoedema, gingival hyperplasia, and higher prevalence and density of Candida albicans, leukoplakia or gingivitis.Patients and methodsWe report herein the appearance of a characteristic green tongue in a patient following intensive marijuana inhalation.DiscussionThis complication has rarely been reported in the medical literature. Paradoxically, it is clearly described in different Internet search engines, particularly Google.

IntroductionNous rapportons un cas de lymphome T cutané et systémique ayant résisté au traitement conventionnel et dont l'évolution a conduit à réaliser une greffe de moelle haplo-identique.ObservationUne femme de 53 ans consultait pour un érythème infiltré du visage, des lésions kératosiques du tronc et des adénopathies centimétriques axillaires et inguinales. Le diagnostic de syndrome de Sézary (SS), forme leucémique d'un lymphome T cutané épidermotrope, était retenu. Après 3 ans de traitement par méthotrexate, la patiente développait un SS transformé avec atteinte viscérale. Le fort risque de rechute et l'absence de donneur HLA-compatible amenait à la réalisation d'une greffe haplo-identique de moelle osseuse. La patiente était en rémission complète à 2 ans et demi. L'évolution était cependant marquée par l'apparition, un an après la greffe, d'une éruption lichénoïde blaschko-distribuée dont l'aspect histologique était compatible avec une réaction du greffon contre l'hôte (GVH) chronique ; elle était traitée efficacement par bétaméthasone topique.DiscussionNous rapportons, à notre connaissance, la première greffe haplo-identique réalisée pour un lymphome cutané T transformé et systémique. Ce traitement pourrait désormais être une option pour les patients nécessitant une allogreffe mais n'ayant pas de donneur compatible. Les lésions lichénoïdes blaschko-distribuées attribuées à une GVH chronique pourraient être la conséquence d'une perte d'immunotolérance vis-à-vis de clones embryologiques anormaux, provoquant ainsi une réaction inflammatoire médiée par les lymphocytes T.BackgroundHerein, we report a case of systemic cutaneous T-cell lymphoma refractory to standard therapy, the course of which resulted in haplo-identical bone marrow grafting.Patients and methodsA 53-year-old woman consulted for facial erythema with infiltration, keratotic lesions on the trunk, and adenopathies measuring around 1cm on the axilla and inguinal folds. A diagnosis was made of Sézary syndrome (SS), a leukaemic form of epidermotropic cutaneous T-cell lymphoma. After three years of treatment with methotrexate, the patient developed transformed SS with visceral involvement. Given the high risk of relapse and the absence of an HLA-compatible donor, haploidentical bone marrow grafting was performed. The patient was still in complete remission two and a half years later. The disease course was nevertheless marked by the emergence one year after grafting of a Blaschko-distributed lichenoid eruption having histological features consistent with chronic graft-versus-host disease (GVHD); treatment with topical betamethasone proved efficacious.DiscussionTo our knowledge, this is the first reported case of haploidentical grafting for systemic and transformed cutaneous T-cell lymphoma. This approach could henceforth represent a therapeutic option for patients requiring an allograft in the absence of compatible donors. The Blaschko-distributed lichenoid lesions attributed to chronic GVHD could be the result of reduced immune tolerance to abnormal embryological clones leading to a T-lymphocyte-mediated inflammatory reaction.

IntroductionChondrosarcoma (CS) is the second most common primary bone sarcoma with no clear role for adjuvant therapy. The purpose of this study was to investigate (1) the relationship between surgical excision margins and local recurrence free survival (LRFS), and (2) the role of local recurrence (LR) in disease specific survival (DSS) in CS of the extremity and pelvis.Material and methods341 pelvic and extremity CS diagnosed between 2003 and 2015 were studied retrospectively.ResultsLR developed in 23% of cases. Pelvic location, pathologic fracture, margin and grade were significant factors for LR after univariate analysis. Multivariate analysis revealed surgical margin and pelvic location as positive factors for LR, and grade-1 and 2 CS as negative factors for LR. Pathologic fracture, central versus peripheral, grade, and LR were significant factors with univariate analysis for DSS; and grade was significant after multivariate analysis for all patients for DSS. After competing risk analysis, LR was statistically significant for DSS in grade-2 and grade-3 tumours.ConclusionSurgical margins determine LR in all CS grades, but LR affects DSS only in grade-2 and grade-3 tumours. Although narrow margins are acceptable in grade-1 tumours, since biopsy is unreliable in predicting final grade, a minimum 4-mm margin should be the aim in all cases.

PurposeTo assess long-term functional and oncologic outcomes of prostate sparing cystectomy (PSC) as a sexuality-preserving alternative to radical cystectomy in a selected group of bladder cancer (BC) patients.Materials and MethodsBetween 1995 and 2014, 185 BC patients underwent PSC according to one of two standardized procedures at two centers. All patients had received extensive evaluation to rule out prostate cancer and BC at the bladder neck and prostatic urethra (PU), including prostate specific antigen blood analysis, transrectal ultrasound and/or prostate biopsies, PU biopsies and/or PU frozen section analysis. All patients received an orthotopic ileal neobladder. Overall survival (OS) was assessed by Kaplan–Meier estimates. Cumulative incidence of cancer specific mortality, any recurrence and loco-regional recurrence were calculated using competing-risk methods. Finally, functional outcomes (voiding, continence and erectile function) were evaluated.Results185 patients (cTa-3N0M0) with a mean age of 57 years (SD: 9) were included. Median follow-up was 7.5 years (IQR: 5.6-10.8). Five-year OS was 71% and 5-year cumulative incidence of recurrence was 31%. Twenty patients (10.8%) had a loco-regional recurrence, two recurrences were in the PU. During follow-up, prostate cancer was detected in six patients (3.2%). Erectile function was preserved in 86.1% of patients, complete daytime and nighttime continence in 95.6% and 70.2%, respectively.ConclusionThis two-center study shows that in men with BC in whom the prostate and PU were proven free of malignancy, PSC would represent a valid treatment option with excellent functional outcome. Oncologic outcomes were comparable to what is known from radical cystoprostatectomy series.

“Location of the Internal Mammary Vessels for Microvascular Autologous Breast Reconstruction: The “1–2–3 Rule”

Background: Postmastectomy breast reconstruction provides psychosocial benefits in self-esteem, sexuality, and quality of life. Autologous procedures yield the highest overall patient satisfaction compared to implant-based breast reconstruction as the gold standard. The internal mammary vessels (IMA/V) are the preferred recipient vessels for free flap breast reconstruction. The study's purpose is to provide surgeons with a reliable method to locate the vessels intraoperatively. Methods: The IMA/V were dissected bilaterally on 30 cadaveric specimens. Distances from the lateral sternal borders (LSBs) and the costochondral junctions (CCJs) to the IMA/V at the 2nd, 3rd and 4th costal levels were recorded. Descriptive bifurcation patterns were recorded. Initial dissection practicums were performed utilizing the proposed safer dissection zone per quantitative data. Results: 60 IMAs and 120 IMVs were studied at 3 costal levels resulting in 180 sets of measurements. Distances from LSB to medial IMV were 6.12 mm, 9.04 mm, and 10.45 mm at costal levels two, three, and four, respectively. Mean distances between CCJs and IMAs were 12.80 mm, 24.78 mm, and 33.28 mm at costal levels two, three, and four, respectively. Most IMV bifurcated at 3rd costal level, and left side bifurcated higher than right. Dissection practicums revealed that the proposed dissection zone was consistently reliable in locating the vessels. Conclusions: This study provides mean measurements from common bony landmarks to the IMA/V, equipping surgeons with a reliable zone of dissection for recipient vessel exposure. This may decrease morbidity and improve outcomes in autologous breast reconstructions.

Role of Fractionated Fat (FractoFat) in Blending the Lid-Cheek Junction

Introduction: Fat grafting is extensively used in plastic surgery in last 2 decades. Here, we report the retrospective comparison of patients who underwent fractionated fat injection to blend the lid-cheek junction with those who had regular fat injection. Method: After obtaining institutional review board approval, a retrospective review of patients who underwent lower blepharoplasty with fractionated fat injection for blending lid-cheek junction from January 2014 through October 2015 was performed. The results were compared to lower blepharoplasty patients who didn't have fractionated fat injected prior to January 2014.Twelve prospectively selected patients underwent histopathological and gene expression comparisons. Results: A comparison of complications between 2 groups revealed no significant difference. Furthermore, there was no significant difference between 2 groups for sequelae of fractionated fat injection and regular fat injection. The gene expression analysis of the fractionated and regular fat didn't have any difference with both undifferentiated and differentiated cells. Additionally, Oil Red O staining of the fractionated and regular fat after differentiation shows that cells from both kinds of fat groups differentiated equally well. Conclusion: Fractionated fat injection appears to be safe addition in blending the lid-cheek junction in the five step lower blepharoplasty. There is no fat nodule formation with injection of fractionated fat injection in comparison to injection of regular fat done superficially in the tear trough area. Contrary to what has previously been shown, the presence of viable cells in fractionated fat was noted.

Prepectoral Implant-Based Breast Reconstruction with Post-Mastectomy Radiation Therapy

Background: Two-stage subpectoral implant-based breast reconstruction (IBBR) is the most common method for breast reconstruction. Recent advances in surgical techniques and technology have made prepectoral IBBR feasible. There is limited data on outcomes after prepectoral IBBR and post-mastectomy radiation therapy (PMRT). Methods: A retrospective review of consecutive patients undergoing immediate two-stage prepectoral IBBR with PMRT was performed. Outcomes of radiated breasts were compared with non-radiated breasts in bilateral cases. Results: Ninety-three cases of prepectoral IBBR in 54 women who underwent immediate two-stage prepectoral IBBR (39 bilateral and 15 unilateral) and unilateral PMRT were identified. Mean follow-up was 19 months from mastectomy and tissue expander reconstruction and nine months from implant placement. Crude complication rates in radiated versus non-radiated sides were as follows: surgical site infection (SSI) 18.5% vs 7.7%, seroma 5.6% vs 5.1%, mastectomy skin flap necrosis 1.9% vs 2.6%, wound dehiscence 1.9% vs 7.7%, capsular contracture 1.9% vs 0%, hematoma 1.9% vs 2.6%, and extrusion 1.9% vs 0%. On univariate analysis there were no risk factors, including radiation, associated with any complication, SSI, unplanned readmissions, and unplanned return to the operating room. To date, reconstruction has been completed in 96% of patients, with successful IBBR in 81 breasts (45 radiated breasts and 36 non-radiated breasts). Conclusion: Early data of prepectoral IBBR in patients with PMRT show promising results. PMRT should not be an absolute contraindication to prepectoral IBBR.

Nipple-sparing mastectomy Incisions for Cancer Extirpation (NICE) Prospective Cohort Trial: Perfusion, Complications, and Patient Outcomes

Background: Nipple-sparing mastectomy (NSM) offers several advantages for women seeking post-mastectomy breast reconstruction, but compromised skin and nipple perfusion may lead to skin and nipple necrosis. It is unclear if the incisional approach contributes to these complications; therefore, the purpose of this study was to compare the impact of incision type on outcomes in patients undergoing NSM. Methods: This is a prospective cohort study of patients undergoing NSM with prosthetic breast reconstruction through an inframammary fold (IMF) versus a lateral radial (LR) incision. Skin and nipple perfusion as represented by fluorescent intensity, mammometric parameters, patient-reported outcomes, and clinical outcomes were analyzed and compared for the two cohorts and multivariable logistic regression models were performed to evaluate effects of covariates on outcomes. Results: 79 patients were studied: 55 in the IMF cohort and 24 in the LR cohort. The IMF group had significantly less fluorescent intensity to the inferior (21.9% vs 36.9%, p=0.001) and lateral portions of breast skin (23.1% vs 40.7%, p=0.003) after reconstruction. Decreased fluorescent intensity was associated with smoking, decreased mean arterial pressure, and greater specimen weight. Post-reconstruction breast volumes were increased over preoperative volumes in the IMF group (38.3%) versus the LR (31.2%) group; however patients with a LR incision had a greater increase in satisfaction with their breasts and psychosocial well-being. Conclusions: There are significant differences in patient-reported outcomes and final breast volumes based on the incisional approach to NSM. These data can be used to guide providers and counsel patients considering NSM with prosthetic reconstruction.

Use of Roof-Shaped Costochondral Cartilage for Correction of Saddle Nose Deformity

Background: Cartilage grafts are routinely used in secondary and post-traumatic rhinoplasty. However, in most cases, there are weak areas in the nasal bones and upper lateral cartilages. The purpose of this study was to seek a solution for keystone area and dorsum of the nose in revision and post-traumatic rhinoplasty cases, and reconstruction of saddle nose deformity including upper lateral cartilage with roof shaped graft. Methods: A retrospective review of reconstructive rhinoplasties performed for saddle nose deformities was conducted. A part of the costochondral graft was carved and thinned (roof graft) for reconstruction of the keystone area and upper lateral cartilages, while another portion was used for making a neo-septal (reconstructed septum) graft and strut graft. Roof graft was capped onto the neo-septal graft with sutures, and this cartilage framework was adapted with fitting the cranial edge of neo-septal cartilage between the nasal bones. Finally strut graft was fixed to the cartilage framework. Results: A significant improvement in nasal shape and overall appearance was achieved in all cases, and 71.42% of patients recovered from nasal obstruction. No gross absorption, graft exposure or recurrence of deformities was observed. Conclusions: Surgical correction of a saddle-shaped nose should be an acceptable and uncomplicated technique, and the cosmetic result should be totally acceptable. There are many management options for a saddle-shaped nose. Use of roof grafts (shrunk gull wing grafts) with neo-septal and strut grafts enables simulation of the internal nasal valve and results in a natural nasal position.

When is Teenage Plastic Surgery vs Cosmetic Surgery OK - Reality vs Hype? – A Systematic Review

Summary: Plastic surgery in teenagers has become popular in past decades due to an increase in self-awareness and desire to "fit in" with their peers. In 2016, over 229,551 cosmetic procedures were performed in patients who are under the age of 19 years old 1. The trend of plastic surgery in adolescents is increasing, and it is important for plastic surgeons to perform safe and appropriate procedures in this group. To this date, there is a myriad of literature on the psychological and ethical issues concerning plastic surgery in teenagers. However, studies regarding the safety of performing plastic surgery in this population are scare 2. The rationale for this review is to study this issue in depth via a systematic review. We will discuss the current indications, safety, patient satisfaction, and ethical considerations of teenage plastic surgery as well as make recommendations for future studies on this important area in plastic surgery.

A report of 736 high definition lipoabdominoplasties performed in conjunction with circumferential Vaser liposuction

Background: Several innovations and modifications to abdominal lipectomy procedure have been performed through the years. Despite the recent improvements, the lack of natural results, including high scars, navel deformities and "tense" abdomen are still challenging. The objective is to present an alternative technique of combined 360-degree truncal liposuction with abdominal definition, abdominoplasty and neoumbilicoplasty. Methods: From January 2005 to June 2017, 736 VASER assisted lipoabdominoplasties were performed. Only healthy women with body mass index below 33 were included. A 3-step procedure was done: 1. Truncal Liposculpture. 2. dermolipectomy and plication of the rectus abdominis muscle. 3. Neo-umbilicoplasty through a butterfly technique. The following included photos and medical assessment with a mean of 2 years (up to 5 years). A non-standardized survey was performed to self-evaluate the results. Results: 670 patients answered the survey (91%). 615 patients were satisfied with the procedure (91.79%). Minor complications were reported: seroma (7.3%), prolonged bruising (10%) and swelling (18%). Neither flap necrosis nor infections were reported. Neo umbilicoplasty was performed in all patients. Additional procedures were required in 4.6%. Conclusions: The Ultrasonic-assisted assisted Lipoabdominoplasty is an alternative lipectomy technique that prevents stigmata of the procedure. The abdominal definition improves the shape and recreate the superficial anatomy. Neoumbilicoplasty shape, form and choice of its position over the abdominal wall gives significant improvements in results.

Human Acellular Dermis as Spacer for Small Joint Arthroplasty: Analysis of Revascularization in a Rabbit Trapeziectomy Model

BACKGROUND: Carpometacarpal (CMC) osteoarthritis affects 8-12% of the general population. Surgical management provides symptomatic relief for 78% of patients who fail conservative therapy, but little consensus exists regarding which surgical procedure provides superior patient outcomes. Recent human trials substituted exogenous acellular dermal matrices (ADMs) in the bone space, but there is no quantitative histological data on the outcome of ADMs in this environment. We aimed to quantify the revascularization and recellularization of ADMs in the joint space using a rabbit model. METHODS: Bilateral lunate carpal bones were surgically removed in New Zealand rabbits. ADM and autologous tissue were implanted in place of the lunate of the right and left wrists, respectively. ADM was also implanted subcutaneously as a non-joint control. Histological and immunofluorescence analysis was performed after collection at zero, six, and twelve weeks. RESULTS: Quantitative analysis of anti- α- smooth muscle actin (SMA) and CD31 immunofluorescence revealed a sequential and comparable increase of vascular lumens in joint space and subcutaneous ADMs. In contrast, autologous tissue implanted in the joint space did not have a similar increase in SMA- or CD31-positive lumens. Semi-quantitative analysis revealed increased cellularity in both autologous and ADM wrist implants at each time point, while average cellularity of subcutaneous ADM peaked at six weeks and regressed by twelve. Trichrome and Sirius Red staining revealed abundant collagen at all time points. CONCLUSIONS: The trapeziectomy joint space supports both cellular and vascular ingrowth into human ADM. * Authors contributed equally Disclosures: This work was funded in part by a grant from the Musculoskeletal Transplant Foundation/Plastic Surgery Foundation.

Changes in Cutaneous Gene Expression after Microvascular Free Tissue Transfer in Parry Romberg Disease

Purpose: Parry Romberg's Disease (PRD) is an enigmatic craniofacial disorder characterized by progressive facial atrophy. The pathogenesis and molecular mechanisms governing PRD have never before been described. The purpose of our current study was two fold; 1) to begin to elucidate the pathophysiology of this disease using next gen RNA sequencing and 2) evaluate the effect of surgical treatment on gene expression. Methods: Patients with PRD underwent microvascular free tissue transfer (MVFF) to the face to address contour deformity in both active and burned out disease. Tissue samples were collected for analysis at the time of initial MVFF, and 6 months later at a scheduled revision surgery. Patients presenting for rhytidectomy had tissue samples taken as control tissue. Patients with disease were compared to control samples. Results: Twenty two subjects were evaluated. (Six control and Sixteen Parry Romberg patients) All patients with PRD underwent MVFF to the face. Thirteen patients underwent scheduled six month revision surgery. Disease samples were distinct from healthy controls, and postoperative patient samples were more similar to healthy control samples. Parry Romberg patients had a unique proinflammatory gene expression profile including upregulation of: IL24, ADAMTS4, and GFCSF3. Postoperatively, more than 3,400 genes were changed (p

Seasonal Impact on Surgical Site Infections in Body Contouring Surgery: A Retrospective Cohort Study of 602 Patients Over a Period of 6 Years

Purpose: Postoperative Surgical Site Infections (SSI) are severe complications following body-contouring-surgery (BCS). Here we evaluate if SSI rates are influenced by higher temperatures during the summer season. Patients and Methods: We enrolled 602 patients who underwent BCS between 2009 and 2015 in a retrospective cohort study. Data collected included demographics, surgical data and postoperative outcome. BCS procedures included lower and upper-bodylift, abdominoplasty, breast-reduction, mastopexy, brachioplasty and thigh-lift. Infection rates were calculated on a seasonal basis and compared using Fisher's-exact test and logistic-regression-analysis. Results: There were 136 patients (125 women; 11 men) in the warm season (June-August; with an average temperature of 67.622°F (19.79°C) and 466 patients (438 women; 28 men) in the cold seasons group (September-May; with an average temperature of 45.45 °F (7.47°C)). The composition of the study cohorts was comparable. Average age was 40 years and average body mass index was 27. From a total of 602 patients we observed 33 SSIs, representing a rate of 5.48%. A statistically significant rise of postoperative SSIs could be detected during summer (10.29% vs. 4.08%, p=0.0071) representing an increase of 150%. Additionally, a logistic regression analysis determined 'season' as the strongest predictor for SSIs with a risk exaltation of 2.693 times in the warm season. Conclusion: BCS are elective procedures making careful risk consideration an absolute prerequisite. We demonstrate a significantly increased infection risk during summer and establish a causal link between the warm season and SSI accumulation. Consequently, preoperative patient information and operative planning should be adjusted accordingly. * These authors contributed equally to this work None of the authors has a financial interest in any of the products, devices, or drugs mentioned in this manuscript.

Novel approach for risk-reducing mastectomy - first stage implant placement and subsequent second stage mastectomy.

Background: Risk-reducing mastectomy (RRM) with tissue expander then implant-based breast reconstruction conventionally involved immediate submuscular placement of tissue expanders during mastectomy, then after expansion, replacement of expanders for permanent implants in a second stage operation. Use of acellular dermal matrix (ADM) can achieve a single staged operation but ADMs are costly and may have potential complications. We aim to assess the feasibility of placement of implants as a first stage before RRM as a novel technique of reconstruction which avoids the need for serial outpatient expansion and ADM. Methods: Patients for RRM were offered first stage dual plane placement of fixed volume silicone gel permanent implants via inframammary fold incisions. RRM was undertaken several months later as the second operation, leaving the implants in place protected by the muscle and capsule pocket. Nipples were preserved or reconstructed according to patient's choice. Results: Eight patients with 15 operated breasts were recruited. Anatomically shaped implants were used in all patients and complete coverage of each implant was achieved. Mean implant volume was 433ml (range: 290-545ml). There were no complications and good aesthetic outcomes were achieved. Conclusions: This proof of principle finds that placement of implants before RRM is a novel technique for women at high breast cancer risk that could reduce the use of tissue expanders and ADMs and their associated problems. Two-staged RRM with first stage implant placement and subsequent RRM leaving the implants in place is feasible with no complications and can produce a good cosmetic outcome.

Opioid Usage Following Outpatient Breast Surgery: Are Physicians Part of the Problem?

Purpose: The increasing rate of opioid abuse warrants standardization of postoperative pain management. The purpose of this study is to analyze the use of opioids in pain control and patient satisfaction following ambulatory breast surgery. Methods: This is a prospective study of a consecutive series of patients undergoing secondary breast reconstruction [SBR: n=60)] or breast reduction [BR:n=35]. All patients were given a pain questionnaire preoperatively. Postoperatively, women received 30 tablets of oxycodone 5.0mg/acetaminophen 325mg. Patients were contacted three times postoperatively: postoperative day [POD] 3-5, 8-10, and >/30. All patients were queried on narcotic usage, pain level (0-10), and satisfaction with pain control. Patients with allergies or taking narcotics preoperatively were excluded. Results: Most in SBR group (61.5%) had stopped taking opioids by POD5. Patients consumed a mean of 11.4 pills following SBR and 17.5 after BR. A majority reported feeling satisfied with their pain management. At POD>/30, most experienced very mild pain with an improvement of 3.74 points following BR. There were 18.6 and 12.5 pills per patient leftover for both SBR and BR, respectively. 1,551 unused pills were leftover entire cohort at POD>/30. There was not a significant difference in average pain scores and interference with enjoyment or activity between those that did or did not take pain medication. Conclusion: This commonly prescribed pain regimen provides adequate pain relief and satisfaction for breast surgery with a substantial number of leftover pills. We as prescribers should be aware of discrepancies. Thirty opioids after outpatient breast surgery appears unnecessary and excessive.

Optimizing Perforator Selection: A Multivariable Analysis of Predictors for Fat Necrosis and Abdominal Morbidity in DIEP Flap Breast Reconstruction

Introduction: This study aims to elucidate the important predicting factors for fat necrosis and abdominal morbidity in the patient undergoing DIEP flap reconstruction. Methods: Retrospective review of 866 free-flap breast reconstructions performed at one institution from 2010-2016. 28 potential predictors were included in multivariable analyses to control for possible confounding interactions. Results: 409 total DIEA perforator flaps were included in our statistical analysis. 14.4% had flap fat necrosis, 21.3% had an abdominal wound or complication, and 6% had an abdominal bulge or hernia. Analysis showed an increase in the odds of fat necrosis with increasing flap weight (OR 1.002 per 1g increase, p-value=. 0002). A decrease in the odds of fat necrosis was seen with lateral row (OR .29, p-value=. 001) and both-row perforator flaps (OR .21, p-value=. 001), if ICG angiography was utilized (OR .46, p-value=. 04), and with increasing total flow rate of the flap (OR .62 per 1 mm/s increase, p-value= .05). Increased odds of abdominal bulge or hernia were seen with lateral or both row perforators (OR 3.21, p-value=. 05) vs. medial row perforator based flaps, and with patients whom had an abdominal wound post-operatively (OR 2.59, p-value=. 05). Conclusions: Our results suggest that utilizing larger caliber perforators and perforators from the lateral row alone, or in addition to medial row perforators, can decrease fat necrosis rather than by simply harvesting more perforators alone. However, lateral and both row perforator flaps come at the cost of increasing abdominal bulge rates.

“Transversus Abdominis Plane Blocks in Microsurgical Breast Reconstruction: Analysis of Pain, Narcotic Consumption, Length of Stay and Cost.”

Background: Transversus abdominis plane (TAP) blocks are increasingly being utilized in microvascular breast reconstruction. The implications of TAP blocks on specific reconstructive, patient and institutional outcomes remain to be fully elucidated. Methods: Patients undergoing abdominally-based microvascular breast reconstruction from 2015-2017 were reviewed. Length of stay, complications, narcotic consumption, donor-site pain and hospital expenses were compared between patients that did and those that did not receive TAP blocks with liposomal bupivacaine. Outcomes were subsequently compared in patients with elevated body mass index (BMI). Results: Fifty patients (43.9%) received TAP blocks (27 [54.0%] under ultrasound guidance) and 64 patients (56.1%) did not. Patients with TAP blocks had significantly decreased oral and total narcotic consumption (p=0.0001 and p

Nitroglycerin Ointment for Reducing the Rate of Mastectomy Flap Necrosis in Immediate Implant Based Breast Reconstruction

Background: Mastectomy flap necrosis (MFN) remains a challenging complication in immediate tissue expander breast reconstruction (ITEBR). Nitroglycerin ointment has been shown to reduce the incidence of MFN in a randomized controlled study, using 45g per breast and treating one side only in bilateral cases. This study was conducted to determine the efficacy of 15g of nitroglycerin ointment per breast - therefore permitting application to both breasts in cases of bilateral mastectomy. Methods: A retrospective cohort study of patients undergoing ITEBR by a single reconstructive surgeon was conducted. The intervention cohort consisted of all patients between June 10, 2015 and June 9, 2016 (94 patients, 158 breasts), where 15g of nitroglycerin ointment was routinely applied per breast. The control cohort consisted of all patients from June 10, 2014 to June 9, 2015 (107 patients, 170 breasts) where nitroglycerin was not applied. All complications were tracked including minor wound healing problems. Results: There was an overall 22% decreased incidence of MFN in the nitroglycerin ointment cohort (47.5% vs. 60.6%, p=0.002), with a 44% reduction in full thickness MFN that trended towards statistical significance (9.5% vs. 16.5%, p=0.06). On multivariate analysis, nitroglycerin application was independently associated with a decrease in MFN or need for mastectomy flap debridement. There was no significant difference in the incidence of post-operative hypotension (3.8 vs. 2.9%) or headache among cohorts. Conclusion: Topical nitroglycerin ointment application to mastectomy skin flaps at 15g per breast is a cost-effective means to decrease the incidence of MFN in unilateral and bilateral ITEBR.

The use of bone dust to correct the open roof deformity in rhinoplasty

Background: Hump removal frequently results in an open roof during rhinoplasty, which is conventionally closed with lateral osteotomies. However, if the patient has a narrow bony vault, then lateral osteotomies are problematic. Here, we present a new and practical approach to fix the open roof deformity. Methods: A total of 240 patients (female, 187; male, 53) were enrolled and operated with the presented technique. This approach has four steps as follows: complete submembranous dissection, the preparation of spreader flaps, harvesting the bone dust from the bony hump, and the placement of the bone dust. The patient's nasal dorsum was evaluated by ultrasonography (US). During the follow-up period, all patients were postoperatively photographed from standart views using a digital camera. Photos were inspected by two independent plastic surgeons. A palpation test for the nasal dorsum was conducted by a senior surgeon to identify any irregularities. A rhinoplasty outcomes evaluation (ROE) questionnaire was administered to all patients at a 1-year follow-up visit. Functional improvement was assessed with self-evaluation nasal patency. The chi-square test was used for statistical analysis. Results: Of the 240 patients, 182 completed the 1-year follow-up period and ROE questionnaire. Thirty-seven patients were evaluated by US at postoperative year 1. During the follow-up period, no resorption or displacement was detected. High patient satisfaction was achieved, and no complications were encountered. Conclusions: The presented four-step surgical concept was useful for rhinoplasty surgeons to successfully manage open roof deformity in selected patients.

“Not all breast implants are equal: a 13-year review of implant longevity and reasons for explantation”

Background: Augmentation mammoplasty is the most common aesthetic procedure. Textured implants control implant position and have improved capsular contracture rates; however, the impact of texturing on longevity and clinical findings at explantation is unclear. Methods: All cases of explantation between January 2005 – April 2017 from an aesthetic practice were reviewed retrospectively. Patient demographics, implant characteristics, time-to-explantation, and clinical presentation and intraoperative findings at explantation were analyzed. Results: 539 breast implants were explanted during the study period: 249 saline, 147 smooth gel, 123 Biocell®, and 20 other nonaggressively textured breast implants. Average time from placement to explantation was 7.5 years, 5.6 years, 4.9 years, and 4.0 years for saline, other textured, smooth gel, and Biocell® implants, respectively (p-value = 3.25e-08). The percentage of implants removed associated with implant performance failure was 50.3%, 57.5%, 75.0%, and 85.4% for smooth gel, saline, other textured, and Biocell® implants, respectively (p-value = 7.25e-09). 21.1% of Biocell® implants versus 1.5% of all other implants presented with pain (p-value = 2.71e-15). 45 Biocell® implants had double capsules; this phenomenon was not observed with any other implant type (p-value = 5.85e-37). Seven Biocell® implants had late seromas, compared to three late seromas with any other implant type (p-value = 0.0013). Conclusions: Here, we provide evidence that Biocell® implants have the shortest time-to-explantation and the highest proportion of implants associated with implant performance failure. This information should complement the informed consent process when selecting an appropriate implant. Financial Disclosure Statement: Nicholas J.

18 F-PSMA-1007 PET/CT at 60 and 120 minutes in patients with prostate cancer: biodistribution, tumour detection and activity kinetics

Abstract

Purpose

PSMA-targeted PET in patients with prostate cancer (PCa) has a significant impact on treatment decisions. By far the most frequently used PSMA ligand is ⁶⁸Ga-labelled PSMA-11. However, due to the availability of larger amounts of activity, ¹⁸F-labelled PSMA ligands are of major interest. The aim of the present study was to evaluate the biodistribution and performance of the novel ¹⁸F-labelled ligand PSMA-1007 at two different time points.

Methods

This retrospective analysis included 40 consecutive patients (mean age 68.7 ± 8.1 years) referred for PSMA PET/CT. ¹⁸F-PSMA-1007 PET/CT was performed for localization of biochemical relapse, primary staging or therapy follow-up. Circular regions of interest were placed on representative slices of the liver, spleen, kidney, abdominal aortic blood pool, bone marrow (fourth lumbar vertebral body), urinary bladder and gluteus muscle at 60 and 120 min after injection. In malignant lesions the maximum standardized uptake (SUV_max) was measured within volumes of interest at both time points. All SUVs at 60 min were compared with those at 120 min after injection.

Results

The activity in the blood pool, urinary bladder and gluteus muscle was very low and decreased significantly over time (P < 0.001). Uptake in the liver, spleen and kidney showed a significant increase over time and uptake in the bone marrow remained stable. Overall, 135 PCa lesions were detected at 60 min and 136 lesions at 120 min after injection. The median SUV_max increased significantly (P < 0.001) from 10.98 to 15.51 between 60 and 120 min.

Conclusion

PCa lesions show a significant increase in ¹⁸F-PSMA-1007 uptake at 120 min compared with 60 min after injection. In addition, accumulation of the tracer in the urinary bladder was very low leading to improved contrast of adjacent PCa lesions. Increasing accumulation in the liver may limit the sensitivity of the tracer in detecting liver metastases.

The role of interim 18 F-FDG PET/CT in prediction of response to ipilimumab treatment in metastatic melanoma

Abstract

Purpose

The aim of the present study was to assess the value of interim ¹⁸F-FDG PET/CT performed after the first two cycles of ipilimumab treatment in the prediction of the final clinical response to this type of immunotherapy.

Methods

The study group comprised 41 patients with unresectable metastatic melanoma scheduled for ipilimumab therapy. Whole-body ¹⁸F-FDG PET/CT was performed before the start of ipilimumab treatment (baseline PET/CT) and after the initial two cycles of ipilimumab treatment (interim PET/CT). Evaluation of patient response to treatment was based on the European Organization for Research and Treatment of Cancer (EORTC) 1999 criteria for PET as well as the recently proposed PET Response Evaluation Criteria for Immunotherapy (PERCIMT). The patients' best clinical response, assessed at a median of 21.4 months (range 6.3–41.9 months) was used as reference.

Results

According to their best clinical response, the patients were divided into two groups: those showing clinical benefit (CB) including stable disease, partial response and complete response (31 patients), and those showing no clinical benefit (no-CB including progressive disease (10 patients). According to the EORTC criteria, interim PET/CT demonstrated progressive metabolic disease (PMD) in 20 patients, stable metabolic disease (SMD) in 11 patients, partial metabolic response (PMR) in 8 patients, and complete metabolic response (CMR) in 2 patients. According to the PERCIMT, interim PET/CT demonstrated PMD in 9 patients, SMD in 24 patients, PMR in 6 patients and CMR in 2 patients. On the basis of the interim PET, the patients were divided in a similar manner to the division according to clinical response into those showing metabolic benefit (MB) including SMD, PMR and CMR, and those showing no metabolic benefit (no-MB) including PMD. According to this dichotomization, the EORTC criteria showed a sensitivity (correctly predicting CB) of 64.5%, a specificity (correctly predicting no-CB) of 90.0%, a positive predictive value (PPV) of 95.2%, a negative predictive value (NPV) of 45.0% and an accuracy of 70.7% in predicting best clinical response. The PERCIMT showed a sensitivity of 93.6%, a specificity of 70.0%, a PPV of 90.6%, a NPV of 77.8% and an accuracy of 87.8%. The McNemar test showed that the PERCIMT had a significantly higher sensitivity than EORTC criteria (p = 0.004), while there was no significant difference in specificity (p = 0.5). The agreement between the two sets of criteria was poor (McNemar test p = 0.001, and accordingly kappa = 0.46).

Conclusion

The application of the recently proposed PERCIMT to interim ¹⁸F-FDG PET/CT provides a more sensitive predictor of final clinical response to immunotherapy than the application of the EORTC criteria in patients with metastatic melanoma.

Amyloid load but not regional glucose metabolism predicts conversion to Alzheimer’s dementia in a memory clinic population

Abstract

Purpose

The value of imaging regional glucose metabolism with [¹⁸F]FDG PET for the prediction of progression from mild cognitive impairment (MCI) to Alzheimer's dementia (AD) is controversial. The predictive value of imaging with [¹⁸F]FDG PET was therefore tested and compared with that of imaging beta-amyloid load with [¹¹C]PIB PET in the same memory clinic population of MCI patients.

Methods

Thirty-nine patients with MCI who had undergone [¹⁸F]FDG as well as [¹¹C]PIB PET were identified from a single-centre clinical registry. [¹⁸F]FDG and [¹¹C]PIB PET images were rated as positive or negative for the presence of regional hypometabolism typical of AD and beta-amyloid deposition, respectively. Raters were blinded to the clinical information. Patients were followed clinically for 2.7 ± 1.2 years after PET. Cox proportional hazards models, adjusted for age and sex, were used to test the predictive value of [¹⁸F]FDG PET, [¹¹C]PIB PET, and both in combination.

Results

[¹⁸F]FDG PET did not significantly predict conversion to AD (p > 0.1). By contrast, models including [¹¹C]PIB PET only (p < 0.05) or both [¹⁸F]FDG and [¹¹C]PIB PET (p < 0.05) significantly predicted conversion to AD. The hazard ratio for AD in patients with a positive [¹¹C]PIB scan was 10.2 (95% confidence interval 1.3–78.1). The results were confirmed by analysis of semiquantitative measures using normalized [¹⁸F]FDG uptake and [¹¹C]PIB standardized uptake value ratios in AD-typical regions as continuous predictors.

Conclusion

In contrast to [¹¹C]PIB PET, [¹⁸F]FDG PET did not predict conversion from MCI to AD in this clinical patient sample. Therefore, amyloid PET should be preferred for individual prediction and patient counselling in clinical practice.

The central zone has increased 68 Ga-PSMA-11 uptake: “Mickey Mouse ears” can be hot on 68 Ga-PSMA-11 PET

Abstract

Purpose

Given the good correlation between PSMA expression and intraglandular tumour aggressiveness based on immunohistochemistry, there is increasing interest in ⁶⁸Ga-PSMA-11 PET/MRI for staging prostate cancer (PCA). Therefore, accurate knowledge of prostate anatomy as well as normal distribution of PSMA within the prostate gland is becoming essential. The aim of this study was to investigate the physiological intraprostatic distribution of ⁶⁸Ga-PSMA-11.

Methods

We retrospectively analysed all patients who underwent a staging ⁶⁸Ga-PSMA-11 PET/MRI scan between June 2016 and January 2018 for high-risk PCA, underwent radical prostatectomy in our institution, and gave written consent for further data analysis. In each patient, standardized volumes of interest (VOIs) were placed bilaterally in the central, transition and peripheral zones within the zonal anatomy according to T2 weighted sequences in the axial and coronal planes. VOIs were only placed if they were safely within healthy tissue without spillover from the PCA. SUV_max and SUV_mean were determined and their differences among the regions were assessed using the Wilcoxon signed-ranks test.

Results

Of 283 consecutive patients scanned with ⁶⁸Ga-PSMA-11 PET/MR, 31 were analysed. A total of 133 VOIs were placed, 46 in the central zone, 41 in the transition zone and 46 in the peripheral zone. Differences in SUV_max between the central zone (mean 3.9 ± 0.58) and transition zone (mean 3.2 ± 0.59) and between the central zone and peripheral zone (mean 2.7 ± 0.54) were statistically significant (both p < 0.001).

Conclusion

Our results suggest that higher ⁶⁸Ga-PSMA-11 accumulation in the central zone than in the transition and peripheral zones is normal, and leads to a pattern resembling "Mickey Mouse ears" on ⁶⁸Ga-PSMA-11 PET. This pattern could be helpful in avoiding false-positive interpretations of PET scans.

Preoperative [ 18 F]FDG PET/CT tumour heterogeneity index in patients with uterine leiomyosarcoma: a multicentre retrospective study

Abstract

Purpose

We investigated the prognostic value of the tumour heterogeneity index determined on preoperative [¹⁸F]FDG PET/CT in patients with uterine leiomyosarcoma (LMS).

Methods

We retrospectively reviewed patients with uterine LMS who underwent preoperative [¹⁸F]FDG PET/CT scans at three tertiary referral hospitals. The PET/CT parameters maximum standardized uptake value of the primary tumour (SUV_max), metabolic tumour volume (MTV) and total lesion glycolysis were assessed. The negative values of the MTV linear regression slope (nMLRS) according to the SUV thresholds of 2.5 and 3.0 were determined as the tumour heterogeneity index. The value of PET/CT-derived parameters in predicting progression-free survival (PFS) and overall survival (OS) were determined in regression analyses.

Results

Clinicopathological and PET/CT data from 16 patients were reviewed. The median postsurgical follow-up was 21 months (range 4–82 months), and 12 patients (75.0%) experienced recurrence. Tumour size (P = 0.017), SUV_max (P = 0.019), MTV (P = 0.016) and nMLRS (P = 0.008) were significant prognostic factors for recurrence. MTV (P = 0.048) and nMLRS (P = 0.045) were significant prognostic factors for patient survival. nMLRS was correlated with clinicopathological parameters including tumour size (Pearson's correlation coefficient γ = 0.825, P < 0.001) and lymph node metastasis (γ = 0.721, P = 0.004). Patient groups categorized according to the nMLRS cut-off value showed significant differences in PFS (P = 0.033) and OS (P = 0.044).

Conclusion

The preoperative tumour heterogeneity index obtained using the MTV linear regression slope may be a novel and useful prognostic marker in uterine LMS.

Scratch induced thin film buckling for quantitative adhesion measurements

Publication date: 5 October 2018

Adhesion of thin films is one of the most important factors determining reliability of microelectronic devices and semiconductor industry requires quantitative testing methods to effectively compare these interfaces. Several techniques have been developed over the last decades with scratch induced delamination being a rarely studied method. For compressively stressed films on rigid substrates scratching can cause buckling failure and by modeling the delaminations according to the Hutchinson and Suo model the adhesion can be determined quantitatively. Two different sample systems, a tungsten-titanium film on a silicate glass and a silicon nitride film on a silicate glass with a tungsten-titanium overlayer, have been tested using scratch loads in the range of 100–500 mN. This study demonstrates that the scratching resulted in buckles parallel to the scratch trace and triggered further spontaneous buckling. Using the dimensions of the induced buckles the interfacial adhesion energies were quantified. The adhesion energy of the tungsten‑titanium/silicate glass interface was measured to be 2.7 J/m² and of the silicon nitride/silicate glass interface was 1.5 J/m². The results illustrate that the scratch test can be utilized for quantitative adhesion testing of thin films and suggest that scratch induced delamination is a valuable addition to established adhesion measurement techniques.

Inclusion evolution in additive manufactured 316L stainless steel by laser metal deposition process

Publication date: 5 October 2018
Source:Materials & Design, Volume 155
Author(s): Du-Rim Eo, Sun-Hong Park, Jung-Wook Cho
In laser metal deposition (LMD) process, meltpool oxidation is inevitable due to high working temperature, which results in finely dispersed non-metallic inclusions in the steel matrix. In this paper, characteristics of these inclusion, such as number density and mean radius, were controlled by means of changing process parameters, for instance, scan speed and laser power, using AISI 316L stainless steel powders. Subsequently, the yield stress of cast samples from each condition was measured in order to investigate the possibility of utilizing these inclusions in material strengthening. As oxygen contents varied from 306 ppm to 994 ppm, number densities of inclusion varied from 16,900/mm² to 34,000/mm². The yield stress of deposited material was proportional to inclusion number density ranging from 218 MPa to 269 MPa. Oxygen contents were governed by beam intensity and deoxidizer compositions in the powder, while faster scan speed gave smaller inclusion diameter due to shorter time for growth. The composition and viscosity of slag layer, which covered interface between superheated meltpool and atmosphere, brought in a large difference in oxidation kinetic. Compared with conventional casting process, a large number of inclusions were more finely distributed and possess smaller size, meaning that oxide metallurgy can be fully utilized in the LMD process.

Effective design and simulation of surface-based lattice structures featuring volume fraction and cell type grading

Publication date: 5 October 2018

In this paper we present a numerical investigation into surface-based lattice structures with the aim of facilitating their design for additive manufacturing. We give the surface equations for these structures and show how they can be used to tailor their volume fractions. Finite element analysis is used to investigate the effect of cell type, orientation and volume fraction on the elastic moduli of the lattice structures, giving rise to a valuable set of numerical parameters which can be used to design a lattice to provide a specified stiffness. We find the I-WP lattice in the [001] orientation provides the highest stiffness along a single loading direction, but the diamond lattice may be more suitable for cases where lower mechanical anisotropy is important. Our stiffness models enable the construction of a powerful numerical tool for predicting the performance of graded structures. We highlight a particular problem which can arise when two lattice types are hybridised; an aberration leading to structural weakening and high stress concentrations. We put forward a novel solution to this problem and demonstrate its usage. The methods and results detailed in this paper enable the efficient design of lattice structures functionally graded by volume fraction and cell type.

In vitro studies have demonstrated that GM-CSF in combination with other stimulatory factors induces a microbicidal response that control T. gondii infection. We assessed whether GM-CSF alone can control T. gondiireplication in murine microglial cultures. Microglia were collected and cultured with or without GM-CSF and the half of each group was infected with T. gondii. We determined the T. gondii infectivity, cytokines levels, NO and superoxide detection.GM-CSF alone primes microglia, which after infection induces the production of TNF-α and IL-6, leading to NO and superoxide production, without any stimulus from IL-12p70 and IFN-γ.

The nonstructural protein NSs of severe fever with thrombocytopenia syndrome phlebovirus blocks type I interferon (IFN)-stimulated JAK-STAT signaling. However, there is continuing controversy as to whether NSs targets STAT1 or STAT2 or both for this blockade. The present study was designed to gain a further understanding of the blockade mechanism. Immunoprecipitation experiments revealed a stronger interaction of NSs with STAT2 than with any other component constituting the JAK-STAT pathway. Expression of NSs resulted in the formation of cytoplasmic inclusion bodies (IBs), and affected cytoplasmic distribution of STAT2. STAT2 was relocated to NSs-induced IBs. Consequently, NSs inhibited IFN-α-stimulated tyrosine phosphorylation and nuclear translocation of STAT2. These inhibitory effects as well as the signaling blockade activity were not observed in NSs mutant proteins lacking the STAT2-binding ability. In contrast, NSs affected neither subcellular distribution nor phosphorylation of STAT1 in response to IFN-α and IFN-γ, demonstrating that NSs has little physical and functional interactions with STAT1. Taken together, these results suggest that NSs sequesters STAT2 into NSs-induced IBs, thereby blocking type I IFN JAK-STAT signaling.

Little cigars and cigarillos: Affect and perceived relative harm among U.S. adults, 2015

Publication date: October 2018

Author(s): Ban A. Majeed, Amy Nyman, Kymberle L. Sterling, Paul Slovic
IntroductionSimilar to cigarette smoking, consumption of cigars delivers nicotine and byproducts of tobacco combustion and elevates the risk of addiction, illness, and premature death. This study examined the relationship of affect, perceived relative harm, and LCC smoking behavior among U.S. adults.MethodsData were from Tobacco Products and Risk Perceptions Survey conducted in 2015. The study included a probability based sample of 6051 adults (18+) drawn from an online research panel. A current LCC smoker was defined as having ever smoked LCCs and was currently smoking LCCs every day, somedays, or rarely. Participants were asked whether smoking LCCs was less harmful, had about the same level of harm, or was more harmful than smoking regular cigarettes. Feelings about LCCs were collected using word association technique. Descriptive and multinomial logistic regression analyses were conducted.ResultsAbout 7% of the study participants were current LCC smokers. Adults with positive feelings had four-fold the adjusted odds to be current LCC smokers. Perceiving LCCs to be less harmful had 2.7 higher adjusted odds of being current LCC smokers.ConclusionsCompared to cigarettes, LCCs evoked more positive feelings among adults and these positive feelings were strongly associated with both perceiving LCCs as less harmful than cigarettes and with current LCC smoking. Cessation and prevention interventions would benefit from applying the principles of social marketing in which information is provided not only to inform consumers but also to evoke negative feelings and associations with LCC smoking.

ObjectiveTo evaluate symptomatic polyautoimmunity (PA) at childhood-onset systemic lupus erythematosus(cSLE) diagnosis, and its association with demographic data, disease activity, clinical manifestations and laboratorial abnormalities in a large Brazilian cSLE population.MethodsA multicenter retrospective study was performed in 1463 cSLE(ACR criteria) patients from 27 Pediatric Rheumatology services. Symptomatic PA was defined according to the presence of more than one concomitant autoimmune disease(AD) and symptomatic multiple autoimmune syndrome(MAS) was defined as three or more AD. An investigator meeting was held to define the protocol. Demographic data, SLICC classification criteria and SLEDAI-2K were evaluated.ResultsAt cSLE diagnosis symptomatic PA was observed in 144/1463(9.8%) and symptomatic MAS occurred in solely 10/1463(0.7%). In the former group the more frequently observed associated AD were Hashimoto thyroiditis n = 42/144(29%), antiphospholipid syndrome n = 42/144(29%), autoimmune hepatitis n = 26/144(18%) and type 1 diabetes mellitus n = 23/144(15.9%). Further comparisons between cSLE patients with and without PA showed a higher median age(p = 0.016) and lower mean SLICC criteria (p = 0.039) in those with PA. Additionally, these cSLE patients had less renal involvement(35% vs. 44%, p = 0.038) and red blood cell cast(6% vs. 12%, p = 0.042) and more antiphospholipid antibodies(29% vs. 15%, p < 0.0001).ConclusionsApproximately 10% of cSLE had symptomatic PA at diagnosis, particularly endocrine autoimmune disorders and antiphospholipid syndrome. Lupus was characterized by a mild disease onset and MAS was infrequently evidenced. Further studies are necessary to determine if this subgroup of cSLE patients have a distinct genetic background with a less severe disease and a better long-term outcome.
