RESUMEN
BACKGROUND: Mesotherapy is a medical technique that administers cosmetic nutrients directly to the dermis through microdrop injections for aesthetic purposes. Its application has become increasingly widespread. However, there have also been a growing number of reported cases of multiple foreign body granulomas following mesotherapy. It is crucial to find an effective and safe treatment. METHODS: In this study, 31 patients with facial foreign body granuloma after mesotherapy were included. A mixture of 5-fluorouracil, lidocaine injection , and normal saline was prepared in a ratio of 1:1:4 and injected subcutaneously. Triamcinolone acetonide, 5-fluorouracil, lidocaine injection, and normal saline were prepared in a ratio of 2:5:3:10. Subcutaneous injections were administered to each papule using a 34G needle. The treatments were scheduled at intervals of 10-14 days. Color Doppler ultrasound was used to evaluate the condition before the initial treatment and after the final treatment. RESULTS: The preoperative ultrasonography revealed diffuse hypoechoic areas in the dermis of the facial skin. After an average of 2-4 treatment sessions, a significant improvement was observed in all patients' appearance, with reduced redness and swelling, softened nodules, absence of pain and itching symptoms, and no evident abnormal echo on ultrasound examination. During a follow-up period ranging from 1 to 8 months, no recurrence or adverse reactions were reported. CONCLUSION: This technique demonstrates clear efficacy. And this formulation effectively reduces the dosage of triamcinolone acetonide and minimizes the risk of adverse reactions such as skin atrophy. Therefore, it can be considered an effective treatment for multiple foreign body granulomas following mesotherapy.

RESUMEN
BACKGROUND: Chin prosthesis implantation, a cosmetic procedure to correct chin asymmetry, depression, or retraction, is generally safe and simple. However, its long-term effects on surrounding tissues are a concern. This study aimed to use three-dimensional (3D) scanning to classify the mentalis muscle shapes and assess the impact of prosthesis implantation on these muscles. METHOD: This study evaluated 450 eligible female participants. Using three-dimensional imaging, data on the types, thickness, width, and length of the left and right mentalis muscles were collected and summarized. The impact of chin prosthesis on these muscle dimensions was assessed using analysis of variance, and the effect on muscle type was determined using χ2 test. RESULTS: Chin implant placement affected the mentalis muscles, resulting in increased length, thickness, and width. The subjects' mentalis muscles were categorized into 3 types and divided into 7 subtypes. χ2 test results indicated that implantation influences the classification of these muscles. CONCLUSION: Recognizing how implant placement affects the mentalis muscle can guide the development of treatments to mitigate these changes. Additionally, understanding the muscle's morphology enables more precise treatment approaches for patients.

PURPOSE: Various complications following hypospadias surgery present distinct manifestations when examined with ultrasound. Utilizing high-frequency ultrasound, clinicians can promptly identify these complications and initiate appropriate treatment. The aim of this study is to catalogue the ultrasonographic presentations of various postoperative complications following hypospadias surgery, thereby providing a reference for ultrasonographic diagnosis. METHODS: Ultrasonic images of post-hypospadias surgery from October 1, 2015, to June 30, 2023, recorded at the Plastic Surgery Hospital of the Chinese Academy of Medical Sciences, serve as the basis for this investigation. Drawing on patient clinical diagnoses, this study compiles and selects representative ultrasound images of diverse complications. RESULTS: The study encompassed a total of 121 subjects; 26 demonstrated urethral stricture on ultrasonic images, two presented local urethral dilation, six showed intraurethral hair-like structures, 17 revealed intraurethral septum, two exhibited intraurethral fold, one had urethral calculus, one displayed urethral calcification, 12 indicated intraurethral urine accumulation, and two showed urethral diverticulum. CONCLUSION: Ultrasound examination is helpful for postoperative diagnosis following hypospadias, detecting complications such as urethral stricture, urethral hair growth, and urethral diverticulum, which can help doctors choose appropriate clinical treatment strategies.

Background: Botulinum toxin type A (BTA) is becoming more and more prevalent as an injection agent in cosmetic surgery. However, there is an increasing amount of cases reporting unexpected adverse reactions related to BTA injection. BTA can invoke many kinds of hypersensitive reactions, some of which can be delayed-type or even fatal; hence, it is of crucial importance to pay close attention to atypical and early symptoms that may indicate the presence of BTA allergy in patients. Methods: In this study, we reported three cases of mild and unexpected BTA-related hypersensitive reaction with a symptom of nonpruritic erythema on the chest that happened after BTA treatment of upper facial wrinkles and proposed several suggestions based on our practical experience and literature review. Results: Two patients' symptoms were alleviated spontaneously, and one patient's were alleviated after taking oral corticosteroid. According to our literature review, we believe that these incidences indicate a kind of unreported allergic reaction relevant to botulinum toxin. Conclusions: We suggest clinicians consider warily patients' subsequent BTA injection schedule if any suspicious reaction occurs after treatment. We suggest that patients who experience nonpruritic erythema after botulinum toxin injection should suspend subsequent injection plans for at least 3 months to prevent more severe consequences.
RESUMEN
BACKGROUND: In recent years, soft tissue materials have been applied as forehead fillers. Some filling materials need to be removed or refilled in a timely manner in certain situations; therefore, it is important to develop a method to identify the location and type of filling materials. This study summarizes the imaging findings of different filling materials under high-frequency ultrasound, providing a reference for clinical treatment. METHODS: We screened facial ultrasound images performed at the Plastic Surgery Hospital of the Chinese Academy of Medical Sciences from April 2015 to July 2023 and classified and summarized the types of frontal filling materials and their imaging results. RESULTS: This study included ultrasound imaging results from 114 patients, including 39 with hyaluronic acid (HA) filling, 45 with polyacrylamide hydrogel (PAG) filling, 14 who received autologous fat transplantation, 2 who received prosthesis implantation, 2 who received both HA and PAG filling, and 12 who received silicone oil filling. HA mainly manifests as an anechoic zone on ultrasonography, with images divisible into four types. PAG primarily presents as fine punctate echoes, divisible into five types. Fat transplantation presents as a low-echo area with uneven density, divisible into five types. Finally, the silicone oil-filling material appears as a cloud-like high echo on the forehead, visible throughout the entire skin layer, and unclear imaging in deep tissues. CONCLUSION: High-frequency ultrasound is a safe and reliable method to evaluate the type and position of forehead filling materials, which can be easily applied in clinical practice.

When searching over associations between congenital ear abnormalities, especially microtia and affiliated deformities like cleft lip or palate and congenital heart diseases, some clinical analysis and genetic theories are found. A 10-year-old boy sent to the plastic surgery hospital was puzzled by a congenital anterior auricular fistula with fluid trace for more than 9 years. The preoperative diagnoses were branchial cleft fistula and congenital left ear deformity with postoperation of TOF. By browsing over studies on genetic concerns and clinical performance, it may be attributed to a possible association between microtia, branchial cleft fistula, and tetralogy of Fallot, though whose fundamental mechanisms remain concerned.

A rare case of trigeminal neuralgia following injections of Hyaluronic Acid and Botox was documented. In addressing the severe pain and swelling caused by the injection, a novel combination therapy was employed, notably including 5-fluorouracil. The significant improvement observed in this case not only provided clinical insights but also spurred further investigation into the underlying mechanisms linking trigeminal nerve damage to local dermal filler injections. The aim was to glean new medical perspectives and develop practical preventive strategies to mitigate such complications in future cases. This approach highlights the importance of understanding and addressing the potential neurological impacts of cosmetic procedures.

RESUMEN
BACKGROUND: The injection of botulinum toxin into the masseter muscle is an important method for improving hypertrophy. However, some patients may experience adverse reactions, such as sagging of the lower jaw. Therefore, we proposed a method of injecting botulinum toxin into the masseter and platysma muscles that would reduce masseter size and enhance the jawline. OBJECTIVES: The aim of this study was to reduce the masseter size while enhancing the jawline. METHODS: Twenty patients received botulinum toxin injections into the masseter and platysma muscles. Pain levels were evaluated with the visual analog scale. All patients were photographed before and 6 months after treatment. Evaluations were performed based on standardized criteria. The lift index, reduction index, and symmetry index were performed to assess the degree of jawline elevation, masseter size reduction, and jawline symmetry before and after treatment. RESULTS: The mean visual analog scale score of the 20 patients was 2.80 (±1.24). The mean lift index score decreased from 4.93 (±0.34) to 4.53 (±0.37), P < .05. The mean reduction index score decreased from 3.13 (±0.27) to 2.74 (±0.27), P < .05. The mean symmetry index score changed from 0.0393 (±0.0296) to 0.0257 (±0.0246), P < .05. CONCLUSIONS: Botulinum toxin injections into the masseter and platysma muscles through nerve block reduced the masseter size, elevated the jawline, and improved symmetry.

Hemihypertrophy is a rare congenital disorder that causes unequal growth of the extremities, trunk, face, or half of the body. We report a case of a 32-year-old woman with hemihypertrophy-related gastrocnemius hypertrophy treated with botulinum toxin A injection. The patient has received two botulinum toxin A injections, and we measured the thickness of the gastrocnemius muscle using ultrasound and measured the maximum circumference around the calf with the patient in the prone position. The patient's maximum calf circumference was reduced by 1 cm. The thickness of the medial head of the gastrocnemius was reduced by 0.3 cm, and the thickness of the lateral head of the gastrocnemius was reduced by 0.6 cm. Botulinum toxin A injection therapy was effective in treating hemihypertrophy-related gastrocnemius hypertrophy.
RESUMEN
Background: Distant metastases are independent negative prognostic factors for patients with primary malignant cardiac tumors (PMCT). This study aims to further investigate metastatic patterns and their prognostic effects in patients with PMCT. Materials and methods: This multicenter retrospective study included 218 patients with PMCT diagnosed between 2010 and 2017 from Surveillance, Epidemiology, and End Results (SEER) database. Logistic regression was utilized to identify metastatic risk factors. A Chi-square test was performed to assess the metastatic rate. Kaplan-Meier methods and Cox regression analysis were used to analyze the prognostic effects of metastatic patterns. Results: Sarcoma (p = 0.002) and tumor size¿4 cm (p = 0.006) were independent risk factors of distant metastases in patients with PMCT. Single lung metastasis (about 34%) was the most common of all metastatic patterns, and lung metastases occurred more frequently (17.9%) than bone, liver, and brain. Brain metastases had worst overall survival (OS) and cancer-specific survival (CSS) among other metastases, like lung, bone, liver, and brain (OS: HR = 3.20, 95% CI: 1.02-10.00, p = 0.046; CSS: HR = 3.53, 95% CI: 1.09-11.47, p = 0.036). Conclusion: Patients with PMCT who had sarcoma or a tumor larger than 4 cm had a higher risk of distant metastases. Lung was the most common metastatic site, and brain metastases had worst survival among others, such as lung, bone, liver, and brain. The results of this study provide insight for early detection, diagnosis, and treatment of distant metastases associated with PMCT.
RESUMEN
OBJECTIVES: To construct predictive models for predicting overall survival (OS) and cancer-specific survival (CSS) of patients with buccal mucosa cancer (BMC). STUDY DESIGN: Data of 936 patients with BMC were extracted from the Surveillance, Epidemiology, and End Results (SEER) database from 2004 to 2015. Nomograms were constructed based on multivariate Cox regression analyses, and validated using calibration plots, time-dependent receiver operating characteristic curves, and decision curve analyses. RESULTS: Age at diagnosis, marital status, grade, histopathology, SEER stage, tumor size, and surgery were associated with OS, whereas age at diagnosis, grade, histopathology, SEER stage, tumor size, and surgery were associated with CSS (all P < .05). The concordance indexes for OS and CSS were 0.79 and 0.80 in the training cohort, respectively, and those in the validation cohort were 0.78 and 0.80. Time-dependent receiver operating characteristic curves showed great predictability in nomograms. Decision curve analyses demonstrated good clinical value for OS (4%-88%) and CSS (3%-77%) nomograms. Patients were stratified into 3 risk groups, with the worst prognosis in the high-risk subgroup (P < .001). CONCLUSIONS: We developed and validated 2 nomograms predicting OS and CSS and established the corresponding risk classification systems in patients with BMC. These models assisted in precise administration of individual therapeutic regimens.

Background: The influences of marital status on cardiovascular death risk in patients with breast cancer remained unclear. This study aimed to evaluate the associations of different marital status with cardiovascular death risk in patients with breast cancer. Methods: A total of 182,666 female breast cancer patients were enrolled in this study from the Surveillance, Epidemiology, and End Results (SEER) database from 2010 to 2014, and was divided into two groups: married (N=107,043) and unmarried (N=75,623). A 1:1 propensity score matching (PSM) was applied to reduce inter-group bias between the two groups. Competing-risks model was used to assess the associations between different marital status and cardiovascular death risk in patients with breast cancer. Results: After PSM, marital status was an independent predictor for cardiovascular death in patients with breast cancer. Unmarried condition was associated with increased cardiovascular death risk than married condition among breast cancer patients [unadjusted model: hazard ratio (HR) =2.012, 95% confidence interval (CI): 1.835-2.208, P<0.001; Model 1: HR =1.958, 95% CI: 1.785-2.148, P<0.001; Model 2: HR =1.954, 95% CI: 1.781-2.144, P<0.001; Model 3: HR =1.920, 95% CI: 1.748-2.107, P<0.001]. With the exception of separated condition (adjusted HR =0.886, 95% CI: 0.474-1.658, P=0.705), further unmarried subgroups analysis showed that the other three unmarried status were associated with increased cardiovascular death risk as follows: single (adjusted HR =1.623, 95% CI: 1.421-1.853, P<0.001), divorced (adjusted HR =1.394, 95% CI: 1.209-1.608, P<0.001), and widowed (adjusted HR =2.460, 95% CI: 2.227-2.717, P<0.001). In particularly, widowed condition showed the highest cardiovascular death risk in all 4 unmarried subgroups. Conclusions: Unmarried condition (e.g., single, divorced and widowed) was associated with elevated cardiovascular death risk compared with their married counterparts in patients with breast cancer, suggesting that more attention and humanistic care should be paid to unmarried breast cancer patients (especially the widowed patients) in the management of female breast cancer patients.
RESUMEN
BACKGROUND: Helicobacter pylori is a pathogen involved in several gastroduodenal diseases, whose infection mechanisms have not been completely confirmed. To study the specific mechanism of gastropathy caused by H. pylori, we analyzed the gene microarray of gastric mucosa and gastric cells infected by H. pylori through bioinformatics analysis. METHODS: We downloaded GSE60427 and GSE74492 from the Gene Expression Omnibus (GEO) database, screened differentially expressed genes (DEGs), and identified the Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) through R software. The Search Tool for the Retrieval of Interacting Genes (STRING) was applied to establish a protein-protein interaction (PPI) network and Cytoscape was used to identify the top seven hub genes. Besides, we also constructed the gene-microRNA(gene-miRNA) interaction through the miRTarBase v8.0 database by using the NetworkAnalyst tool. RESULTS: One hundred and fifteen DEGs were screened out, with 54 genes up-regulated and 61 genes down-regulated, among which seven hub genes, including "IGF1R," "APOE," "IRS1," "ATF3," "LCN2," "IL2RG," and "PI3," were considered as the main regulatory proteins in gastric cells when infected by H. pylori. CONCLUSION: In this study, hub genes and related signal enrichment pathways of gastropathy infected by H. pylori were analyzed through bioinformatics analysis based on the GSE60427 and GSE74492 datasets.
