BACKGROUND Literature focused on cancer screening and management is lacking in the transgender population.AIM To action to increase contributions to the scientific literature that drives the creation of cancer screening and management protocols for transgender and gender nonconforming(TGNC)patients.METHODS We performed a systematic search of PubMed on January 5th,2022,with the following terms:“TGNC”,OR“transgender”,OR“gender non-conforming”,OR“gender nonbinary”AND“cancer screening”,AND“breast cancer”,AND“cervical cancer”,AND“uterine cancer”,AND“ovarian cancer”,AND“prostate cancer”,AND“testicular cancer”,AND“surveillance”,AND“follow-up”,AND“management”.70 unique publications were used.The findings are discussed under“Screening”and“Management”categories.RESULTS Screening:Current cancer screening recommendations default to cis-gender protocols.However,long-term genderaffirming hormone therapy and loss to follow-up from the gender-specific specialties contribute to a higher risk for cancer development and possible delayed detection.The only known screening guidelines made specifically for this population are from the American College of Radiology for breast cancer.Management:Prior to undergoing Gender Affirmation Surgery(GAS),discussion should address cancer screening and management in the organs remaining in situ.Cancer treatment in this population requires consideration for chemotherapy,radiation,surgery and/or reconstruction.Modification of hormone therapy is decided on a case-by-case basis.The use of prophylactic vs aesthetic techniques in surgery is still debated.CONCLUSION When assessing transgender individuals for GAS,a discussion on the future oncologic risk of the sex-specific organs remaining in situ is essential.Cancer management in this population requires a multidisciplinary approach while the care should be highly individualized with considerations to social,medical,surgical and gender affirming surgery related specifications.Special considerations have to be made during planning for GAS as surgery will alter the anatomy and may render the organ difficult to sample for screening purposes.A discussion with the patient regarding the oncologic risk of remaining organs is imperative prior to GAS.Other special considerations to screening such as the conscious or unconscious will to unassociated with their remaining organs is also a key point to address.We currently lack high quality studies pertinent to the cancer topic in the gender affirmation literature.Further research is required to ensure more comprehensive and individualized care for this population. 展开更多

Background: The prevalence of carpal tunnel syndrome (CTS) and of anxiety and depression in primary care practice are high. Different studies had shown an increased prevalence of anxiety and depression in CTS patients. Nevertheless, few papers had been published studying the anxiety and depression scales in the treatment of CTS, either with corticosteroid injections (I) or with surgical decompression (S). Objective: To assess whether clinical improvement observed after the treatment of CTS either with I or with S correlates with an improvement in the punctuations of the Hospital Anxiety and Depression scales (HADS), at 3, 6 and 12-month follow-up. Methods: Randomized and open-label clinical trial, comparing I and S. Patients with symptoms suggestive of CTS (nocturnal paraesthesias) of at least 3 months duration and neurophysiological confirmation were included. Patients with clinically apparent motor impairment were excluded. The subjective evaluation of symptoms was carried out using the visual-analogue scale of pain (VAS-p). Clinical reviews were performed 3, 6 and 12 months after treatment. Each patient completed the HADS questionnaire and a VAS-p at 0, 3, 6, and 12 months. Statistical significance was established using the Student’s t test and the Mann-Whitney U test when necessary. A linear regression analysis was used to know the effect of the treatment adjusted for the initial score of both scales. Results: 65 patients were included (30 in group I and 35 in group S). There was no statistical difference between both groups in terms of age, gender distribution, disease duration, VAS-p, neurophysiological testing severity of CTS or the 8 subscales of HADS. Both groups improved significantly in relation to the baseline VAS-p values, in the reviews at 3, 6 and 12 months, with no significant differences between I and S. At 6 months, the reduction in the anxiety scale was around 3 points for both treatments (S = 3.6 and I = 3.2), without reaching significant differences. At 12 months, it was somewhat higher for those treated with I, but always around 3 points and without significant differences. The Depression scale score was slightly reduced at 6 months, and in a similar way for both groups (I = 1 and S = 1.19;p = 0.8). After 12 months, group I doubled the previous reduction, with group S experiencing a very slight change (I = 1.96 and S = 1.03;p = 0.3). When analysing the effect of group S on group I, the result was a reduction of 0.25 points for Anxiety (p = 0.7) and of 0.02 points for Depression (p = 0.9). Conclusions: Treatment of CTS with I or S results in a similar and discrete improvement in Anxiety scores on the HADS scale at 6 and 12 months. For both types of treatment, the Depression scores barely changed at 6 months, being somewhat higher in group I after 12-month follow-up. The independent effect of the S on both scales is small and not significant. 展开更多

BACKGROUND In rhinoplasty,calcification around silicone implants is frequently observed in the tip dorsum(TD)area.Additionally,based on a review of various literature,it is presumed that calcification in silicone implants occurs due to both inflammatory chemical reactions and physical friction against the tissue.The calcification of nasal silicone implants not only results in the functional loss of the implants,but also leads to material deformation.However,there is a lack of research on calcification of nasal silicone implants in the current literature.AIM To elucidate various clinical characteristics of calcification around nasal silicone implants,using histological and radiological analysis.METHODS This study analyzed data from 16 patients of calcified nasal implants,who underwent revision rhinoplasty for various reasons after undergoing augmentation rhinoplasty with silicone implants.The collected data included information on implant duration,implant types,location of calcification,presence of inflammatory reactions,and computed tomography(CT)scans.RESULTS The most common location of calcification,as visually analyzed,was in the TD area,accounting for 56%.Additionally,the analysis of CT scans revealed a trend of increasing Hounsfield Unit values for calcification with the duration of implantation,although this trend was not statistically significant(P=0.139).CONCLUSION Our study shows that reducing the frequency of calcification may be achievable by using softer silicone implants and by minimizing the damage to perioperative tissues. 展开更多

BACKGROUND Circulating tumor cell(CTC)count and neutrophil-to-lymphocyte ratio(NLR)are both closely associated with the prognosis of hepatocellular carcinoma(HCC).AIM To investigate the prognostic value of combining these two indicators in HCC.METHODS Clinical data were collected from patients with advanced HCC who received im-mune therapy combined with targeted therapy at the Department of Oncology,the Affiliated Hospital of Southwest Medical University,Sichuan,China,from 2021 to 2023.The optimal cutoff values for CTC programmed death-ligand 1(PD-L1)(+)>1 or CTC PD-L1(+)≤1 and NLR>3.89 or NLR≤3.89 were evaluated using X-Tile software.Patients were categorized into three groups based on CTC PD-L1(+)counts and NLR:CTC-NLR(0),CTC-NLR(1),and CTC-NLR(2).The relationship between CTC-NLR and clinical variables as well as survival rates was assessed.RESULTS Patients with high CTC PD-L1(+)expression or NLR at baseline had shorter median progression-free survival(m-PFS)and median overall survival(mOS)than those with low levels of CTC PD-L1(+)or NLR(P<0.001).Mean-while,patients in the CTC-NLR(2)group showed a significant decrease in mPFS and mOS.Cox regression analysis revealed that alpha-fetoprotein(AFP),CTC PD-L1(+),and CTC-NLR were independent predictors of OS.The time-dependent receiver operating characteristic curve showed that the area under the curve of CTC-NLR at 12 months(0.821)and 18 months(0.821)was superior to that of AFP and CTC PD-L1(+).CONCLUSION HCC patients with high CTC PD-L1(+)or NLR expression tend to exhibit poor prognosis,and a high baseline CTC-NLR score may indicate low survival.CTC-NLR may serve as an effective prognostic indicator for patients with advanced HCC receiving immunotherapy combined with targeted therapy. 展开更多

BACKGROUND Osteoporosis is a common metabolic bone disorder induced by an imbalance between osteoclastic activity and osteogenic activity.During osteoporosis,bone mesenchymal stem cells(BMSCs)exhibit an increased ability to differentiate into adipocytes and a decreased ability to differentiate into osteoblasts,resulting in bone loss.Jumonji domain-containing 1C(JMJD1C)has been demonstrated to suppress osteoclastogenesis.AIM To examine the effect of JMJD1C on the osteogenesis of BMSCs and the potential underlying mechanism.METHODS BMSCs were isolated from mouse bone marrow tissues.Oil Red O staining,Alizarin red staining,alkaline phosphatase staining and the expression of adipo-genic and osteogenic-associated genes were assessed to determine the differen-tiation of BMSCs.Bone marrow-derived macrophages(BMMs)were incubated with receptor activator of nuclear factor-kappaΒligand to induce osteoclast differentiation,and osteoclast differen-tiation was confirmed by tartrate-resistant acid phosphatase staining.Other related genes were measured via reverse transcription coupled to the quantitative polymerase chain reaction and western blotting.Enzyme-linked immunosorbent assays were used to measure the levels of inflammatory cytokines,including tumor necrosis factor alpha,interleukin-6 and interleukin-1 beta.RESULTS The osteogenic and adipogenic differentiation potential of BMSCs isolated from mouse bone marrow samples was evaluated.JMJD1C mRNA and protein expression was upregulated in BMSCs after osteoblast induction,while p-nuclear factor-κB(NF-κB)and inflammatory cytokines were not significantly altered.Knockdown of JMJD1C repressed osteogenic differentiation and enhanced NF-κB activation and inflammatory cytokine release in BMSCs.Moreover,JMJD1C expression decreased during BMM osteoclast differentiation.CONCLUSION The JMJD1C/NF-κB signaling pathway is potentially involved in BMSC osteogenic differentiation and may play vital roles in the pathogenesis of osteoporosis. 展开更多

The aging of the periocular region has always aroused great interest.A fresh,young,and attractive sight determined an ever-greater attention to surgical and non-surgical techniques to obtain this result.In particular,the change in the concept of a young look,considered then“full”,led to the increasing use of surgical(fat grafting)or medical(hyaluronic acid)filling techniques.Eyelid rejuvenation became increasingly popular in the field of cosmetic treatments,with a focus on achieving a youthful and refreshed appearance.Among the various techniques available,the choice between using fat grafting or fillers presented a clinical dilemma.In particular,what surgery considered of fundamental importance was a long-lasting result over time.On the other hand,aesthetic medicine considered it fundamental not to have to resort to invasive treatments.But what was the reality?Was there one path better than the other,and above all,was there a better path for patients?The minireview aims to explore the physiopathology,diagnosis,treatment options,prognosis,and future studies regarding this dilemma.We analyzed the literature produced in the last 20 years comparing the two techniques.Current literature reveals advancements in biomaterials,stem cell research and tissue engineering held promise for further enhancing the field of eyelid rejuvenation.The choice between fat grafting and fillers in eyelid cosmetic treatments presented a clinical dilemma.Understanding physiopathology,accurately diagnosing eyelid aging,exploring treatment options,assessing prognosis,and conducting future studies were essential for providing optimal care to patients seeking eyelid rejuvenation. 展开更多

Apart from listening to the cry of a healthy newborn,it is the declaration by the attending paediatrician in the labour room that the child is normal which brings utmost joy to parents.The global incidence of children born with congenital anomalies has been reported to be 3%-6%with more than 90%of these occurring in low-and middle-income group countries.The exact percentages/total numbers of children requiring surgical treatment cannot be estimated for several reasons.These children are operated under several surgical disciplines,viz,paediatric-,plastic reconstructive,neuro-,cardiothoracic-,orthopaedic surgery etc.These conditions may be life-threatening,e.g.,trachea-oesophageal fistula,critical pulmonary stenosis,etc.and require immediate surgical intervention.Some,e.g.,hydrocephalus,may need intervention as soon as the patient is fit for surgery.Some,e.g.,patent ductus arteriosus need‘wait and watch’policy up to a certain age in the hope of spontaneous recovery.Another extremely important category is that of patients where the operative intervention is done based on their age.Almost all the congenital anomalies coming under care of a plastic surgeon are operated as elective surgery(many as multiple stages of correction)at appropriate ages.There are advantages and disadvantages of intervention at different ages.In this article,we present a review of optimal timings,along with reasoning,for surgery of many of the common congenital anomalies which are treated by plastic surgeons.Obstetricians,paediatricians and general practitioners/family physicians,who most often are the first ones to come across such children,must know to guide the parents appropriately and convincingly impress upon the them as to why their child should not be operated immediately and also the consequences of too soon or too late. 展开更多

BACKGROUND Endometrial cancer(EC)is a common gynecological malignancy,but metastasis to the abdominal wall is extremely rare.Therefore,an appropriate treatment approach for large metastatic lesions with infection remains a great challenge.CASE SUMMARY We report the case of a 65-year-old woman who developed abdominal metastasis of endometrioid adenocarcinoma,as defined by International Obstetrics and Gynecology stage II,in which the lesion was complicated by infection.A right hemicolectomy was performed for colon metastasis in relation to her initial gynecological cancer 3 years ago.When admitted to our department,a complete resection of the giant abdominal wall lesion was performed,and a Bard composite mesh was used to reconstruct the abdominal wall.A local flap was used to close the resultant large defect in the external covering of the abdomen.The patient underwent chemotherapy following cytoreductive surgery.Pathology revealed metastasis of EC,and molecular subtyping showed copy number high of TP53 mutation,implying a poor prognosis.CONCLUSION When EC patients develop giant abdominal wall metastasis,a plastic surgeon should be included before contemplating resection of tumors. 展开更多

Autologous fat grafting is an increasingly popular technique in plastic surgery for volume augmentation and rejuvenation.However,the unpredictability of long-term volume retention limits its clinical application.Various animal studies have documented the positive effects of adipose tissue-derived stem cells(ADSCs)on the acceleration of lipofilling.However,the results have been inconsistent,and there is an insufficient number of high-quality clinical studies to formulate evidence-based recommendations for ADSC-enriched fat grafts.Moreover,related technical standards,such as the final count of harvested ADSCs and the enrichment ratio,have not yet been established.This systematic review included all clinical trials on ADSC-enriched fat grafts in plastic surgery from PubMed in the past 10 years,as well as all registered clinical trials on ClinicalTrials.Gov.To examine the current landscape of ADSCs harvest,we summarize the current applications of ADSCs in the field of plastic surgery and discuss the current barriers to universal clinical use. 展开更多

This study examined the effects of a combined surgery of sleeve gastrectomy (SG) and modified jejunoileal bypass (JIB) on the body weight, food intake, and the plasma levels of active glucagon-like peptide-1 (GLP-1) and total ghrelin of rats. Rats were divided into 3 groups in terms of different surgical protocol: SG-JIB (n=12), SG (n=12), JIB (n=12) and sham surgery groups (n-10). In SG-JIB group, rats was subjected to sleeve gastrectomy and end to side anastomosis of part of the jejunum (25 cm from the ligament of Treitz) to the ileum 25 cm proximal to the cecum. The body weight and food intake were evaluated during 10 consecutive weeks postoperatively. The levels of active GLP-1 and total ghrelin in the plasma of the rats were measured by ELISA assay. The results showed that the SG-JIB treated rats relative to SG- or JIB-treated ones produced a sustained reduction in food intake and weight gain. The level of active GLP-1 was elevated and total ghrelin level decreased in SG-JIB-treated rats as compared with SG- or JIB-treated ones. It was concluded that SG-JIB could efficiently reduce the body weight and food intake, alter obesity-related hormone levels of the rats, indicating that SG-JIB may be potentially used for the treatment of obesity. 展开更多

The application of autologous fat grafting in reconstructive surgery is commonly used to improve functional form.This review aims to provide an overview of the scientific evidence on the biology of adipose tissue,the role of adipose-derived stem cells,and the indications of adipose tissue grafting in peripheral nerve surgery.Adipose tissue is easily accessible through the lower abdomen and inner thighs.Non-vascularized adipose tissue grafting does not support oxidative and ischemic stress,resulting in variable survival of adipocytes within the first 24 hours.Enrichment of adipose tissue with a stromal vascular fraction is purported to increase the number of adipose-derived stem cells and is postulated to augment the long-term stability of adipose tissue grafts.Basic science nerve research suggests an increase in nerve regeneration and nerve revascularization,and a decrease in nerve fibrosis after the addition of adipose-derived stem cells or adipose tissue.In clinical studies,the use of autologous lipofilling is mostly applied to secondary carpal tunnel release revisions with promising results.Since the use of adipose-derived stem cells in peripheral nerve reconstruction is relatively new,more studies are needed to explore safety and long-term effects on peripheral nerve regeneration.The Food and Drug Administration stipulates that adipose-derived stem cell transplantation should be minimally manipulated,enzyme-free,and used in the same surgical procedure,e.g.adipose tissue grafts that contain native adipose-derived stem cells or stromal vascular fraction.Future research may be shifted towards the use of tissue-engineered adipose tissue to create a supportive microenvironment for autologous graft survival.Shelf-ready alternatives could be enhanced with adipose-derived stem cells or growth factors and eliminate the need for adipose tissue harvest. 展开更多

The process of lymphatic metastasis was proved to be associated with podoplanin-expressing macrophages in breast cancer(BC).This study aimed to investigate the role of the M2 phenotype of tumor-associated macrophages and mine the key M2 macrophages-related genes for lymph node metastasis in BC.We downloaded the GSE158399 dataset from the Gene Expression Omnibus(GEO)database,which includes transcriptomic profiles of individual cells from primary tumors,negative lymph nodes(NLNs),and positive lymph nodes(PLNs)of breast cancer patients.The cell subsets were identified by clustering analysis after quality control of the scRNA-seq using Seurat.The activation and migration capability of M2 macrophages were evaluated with R package“GSVA”.The key M2 macrophages-related genes were screened from the differential expressed genes(DEGs)and M2 macrophages activation and migration gene sets collected from MSigDB database.Our analysis identified three main cell types in primary tumors,NLNs,and PLNs:basal cells,luminal cells,and immune cell subsets.The further cell type classification of immune cell subsets indicated M2 macrophages accumulation in NLs and PLs.The GSVA enrichment scores for activation and migration capability were increased significantly in M2 macrophages from primary tumors than NLNs and PLNs(pvalue<0.001).Seven M2 macrophages activation-related and 15 M2 macrophages migration-related genes were significantly up-regulated in primary tumors than NLNs and PLNs.The proportion and GSVA enrichment scores for activation and migration of M2 macrophages may be potential markers for lymph node metastasis in breast cancer.Our study demonstrated that twenty-two up-regulated mRNA may be possible therapeutic targets for lymph node metastasis in breast cancer. 展开更多

Oral cancer is usually treated combining surgery, radiation therapy and chemotherapy, following effective therapeutic protocols. Severe maxillary and mandibular bone atrophy resulting after therapies are usually treated with autologous bone grafting procedures even though these techniques often present a significant risk of postoperative complications and disadvantages. We describe the case of a 59-year-old woman presenting severe bone defect after being treated with surgery and radiotherapy for recurrent oral verrucous squamous cell carcinoma. We performed bone regeneration using Platelet-Derived Growth Factors (PDGF) in combination with autologous bone chips. Our procedure of bone regeneration allowed the placement of dental implants and the achievement of a good aesthetic and functional result. Regenerative surgery may enable the regeneration of substantial bone defects. Moreover, PDGF application decreases the risk of implant failure in irradiated patients. 展开更多

Objective:The effects of combined dexmedetomidine hydrochloride and propofol in minimally invasive axillary odor surgery with tumescent anesthesia.Methods:A total of 46 patients underwent minimally invasive axillary odor surgery by tumescent anesthesia received in the hospital from May 2017 to January 2019 were divided into observation group(23 cases)and control group(23 cases)according to the random number table method.The control group used propofol,and the observation group underwent minimally invasive axillary odor combined with dexmedetomidine hydrochloride by tumescent anesthesia.The changes of arterial blood pressure(MAP),heart rate(HR)and postoperative complications before and after anesthesia were compared and analyzed between the two groups.Results:After anesthesia,MAP and HR in both groups were lower than before anesthesia,and the observation group was lower than the control group,the difference was statistically significant(P<0.05).Compared with the control group,the postoperative complications were less in the observation group,but the difference was not statistically significant(P>0.05).Conclusion:Compared with the use of propofol,the effect of dexmedetomidine hydrochloride combined with minimally invasive axillary odor surgery by tumescent anesthesia is more obvious,and the postoperative recovery is faster with fewer complications. 展开更多

Background Accurate preoperative evaluation of the levator palpebrae superioris(LPS)strength is required for specific calculation of anterior migration or shortening.This information serves as a surgical reference for more accurate correction of ptosis.Methods Between June 2017 and June 2019,155 eyes of 97 patients were studied.Patients were divided into the following 3 groups based on the ptosis degree:mild(28 cases),moderate(53 cases),and severe(16 cases).The LPS strength was evaluated preoperatively and used to calculate LPS anterior migration and shortening.The LPS aponeurosis and Müller’s muscle(L-M)complex was separated from the upper margin of the tarsal plate to the calculated height according to the levator muscle suspension system retention approach.The complex was subsequently fixed to the planned tarsal plate location.The upper eyelid margin(UEM)height,eyelid morphology,eyelid closure,eye symmetry,exposure keratitis status,and patient satisfaction were evaluated at 1 week and at 1 and 6 months postoperatively.Results In all cases,the UEM positions were normal,and only patients with severe ptosis exhibited lagophthalmos in the early posterative period.Six months postoperatively,13%of eyes in the severe group had residual ptosis;all mild and moderate cases exhibited good surgical outcomes.The eyelids closed well with no exposure keratitis.All patients were satisfied with the eyelid contour.Conclusions Accurate LPS anterior migration and aponeurosis shortening can eliminate various factors affecting surgical blepharoptosis treatment.These procedures not only reduce operation time but also enhance the stability of postoperative correction. 展开更多
