Request AccessApplication of High-Frequency Ultrasound to Evaluate Forehead Filling Materials.
Aesthetic Plastic SurgeryIn 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.

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.
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.
Long-Term Comparison of Esthetic Outcomes Between Hatchet and Transposition Flaps in Facial-Defect Reconstruction.
Aesthetic Plastic SurgeryTransposition flaps are commonly used for facial-defect repair after wide excision of skin cancers. However, such repair often causes excessive tension at the donor site that can result in distortion of the adjacent area. The hatchet flap, a rotation-advancement flap, can prevent distortion by redistributing the donor site tension evenly to the recipient site. This study aims to compare the esthetic outcomes of the hatchet flap and transposition flap in facial-defect reconstruction.

Thirty patients and 20 patients underwent reconstruction using the hatchet flap and the transposition flap, respectively. The total score from the patient and observer scar assessment scale was significantly lower in the hatchet flap group compared with the transposition flap group (p = 0.009). The Manchester scar scale showed a total score of 7.67 ± 2.2 for the hatchet flap and 9.95 ± 1.99 for the transposition flap: in the color (p < 0.001), distortion (p < 0.001), and texture (p < 0.02) categories, the hatchet flap yielded significantly better outcomes than the transposition flap.
The hatchet flap had good esthetic outcome for facial reconstruction and could be a valuable option for reconstructing facial defects.

Using Photogrammetry to Analyze Anatomical Changes in the Nipple in Juvenile and Adolescent Scoliosis Patients.
Aesthetic Plastic SurgeryThe need for an objective set of anterior trunk measurements, such as nipple and clavicular shoulder joints, is essential to quantify the anterior asymmetry present in scoliosis. This study aims to characterize breast asymmetry (BA) in young individuals with scoliosis using photogrammetry.
This journal requires that authors assign a level of evidence to each article. For a full description of these Evidence-Based Medicine ratings, please refer to the Table of Contents or the online Instructions to Authors www.springer.com/00266 .
The majority of patients had a right breast that was larger, intensifying the apparent BA due to trunk rotation. The apical vertebra level in patients was found at T8 in 23.6% and T9 in 45.1%. In 92.5% of the patients, the right breast was consistently larger. The lengths between the lateral boundaries and nipples of the right and left breasts and between the medial boundary and nipple of the right breast were statistically significantly higher in males than in females (p < 0.05). Significant differences were found when comparing the values of the lengths between the medial boundaries and nipples of the right and left breasts, the difference in length between the right and left acromioclavicular joint lines, and the angles of the nipple and acromioclavicular joint with the degrees of scoliosis in juvenile and adolescents (p < 0.05). Pearson regression analysis revealed a significant correlation between BA differences and the Cobb angle with a correlation coefficient of 0.901. Factors related to breast aesthetics, like differences in the height of nipples and the distance from the sternal notch to the nipple, represent 30% of the overall score.
The study concluded that there is a significant correlation between the severity of scoliosis and BA differences. Augmentation mammaplasty for BA not only decreased the breast difference but also leveled the nipple disparities. Photogrammetry is considered to be an alternative to other methods and is believed to contribute to the follow-up of BA.
Transition to Medicare Does Not Contribute to Rise in Outpatient Visits for Nonmelanoma Skin Cancer, Actinic Keratosis, or Actinic Cheilitis in the US Population.
Dermatol SurgOutpatient visits for nonmelanoma skin cancer (NMSC) and actinic keratoses (AK) have risen steadily in the United States, notably among Medicare beneficiaries. Individuals may delay seeking care for minimally symptomatic conditions until they qualify for Medicare coverage, indicating potential delay of nonurgent screening interventions for uninsured or underinsured patients younger than 65 years.
This study investigates whether an atypical increase in outpatient visits for NMSC, AK, or actinic cheilitis (AC) occurs at the age of Medicare transition by utilizing the National Ambulatory Care Survey from 1993 to 2019.
The National Ambulatory Care Survey data were analyzed for patients aged within 5 years of 65 years. Diagnoses were identified using International Classification of Diseases codes. Linear regression and outlier detection were used to identify a relationship between Medicare eligibility and outpatient visits for NMSC and AK/AC.
Predicted visits for AK/AC and NMSC increased with age. However, there was no evidence of a disproportionate increase in outpatient visits for NMSC and AK/AC at the age of Medicare eligibility.
Outside evidence indicates health care utilization increases after Medicare transition. This study's data do not support a corresponding rise in outpatient visits for NMSC and AK/AC at the age of Medicare eligibility.
Clinical and Dermoscopic Insights Into Scalp Nevi in Chinese Children.
Dermatol SurgThe presence of scalp nevi in children frequently causes apprehension, leading physicians and parents to consider unnecessary biopsies or excisions of scalp nevi in children. There are limited data on the dermoscopic characteristics of scalp nevi in Chinese children.
The aim of this study was to comprehensively analyze the clinical and dermoscopic features of scalp nevi in this specific population of Chinese pediatric patients, with a focus on a single pediatric dermatologic surgery practice.
This retrospective cohort study investigated patients who underwent surgical excision of scalp nevi. All patients underwent dermoscopy with photographic documentation.
Seventy-two scalp nevi in 56 Chinese children were included. Notably, no melanoma cases were detected. The parietal region (35, 48.6%) was the most frequently affected anatomical site. Clinical asymmetry was more prevalent in nevi with a diameter exceeding 6 mm (p < .05). The predominant dermoscopic pattern observed was the globular pattern (50, 69.4%) while an intriguing rarity of a reverse-eclipse pattern (1, 1.4%).
This study revealed that scalp nevi in Chinese children usually did not exhibit concerning behavior. Increasing awareness of the clinical characteristics, dermoscopic features, and the natural progression of scalp nevi in children can potentially help reduce unnecessary surgical interventions.
Performance of ChatGPT in Answering Clinical Questions on the Practical Guideline of Blepharoptosis.
Aesthetic Plastic SurgeryChatGPT is a free artificial intelligence (AI) language model developed and released by OpenAI in late 2022. This study aimed to evaluate the performance of ChatGPT to accurately answer clinical questions (CQs) on the Guideline for the Management of Blepharoptosis published by the American Society of Plastic Surgeons (ASPS) in 2022.
Observational study under respected authorities. This journal requires that authors assign a level of evidence to each article. For a full description of these Evidence-Based Medicine ratings, please refer to the Table of Contents or the online Instructions to Authors www.springer.com/00266 .
A total of 11 questions were included in the final analysis, and ChatGPT answered 61.3% of these correctly. ChatGPT demonstrated a higher accuracy rate in English answers for CQs compared to Japanese answers for CQs (76.4% versus 46.4%; p = 0.004) and word counts (123 words versus 35.9 words; p = 0.004). No statistical differences were noted for evidence quality, recommendation strength, and reference match. A total of 697 references were proposed, but only 216 of them (31.0%) existed.
ChatGPT demonstrates potential as an adjunctive tool in the management of blepharoptosis. However, it is crucial to recognize that the existing AI model has distinct limitations, and its primary role should be to complement the expertise of medical professionals.
Exploring Complication Rates: A Comparative Study of Breast Reduction and Combined Breast Reduction with Abdominoplasty.
Aesthetic Plastic SurgeryDespite a trend towards combining abdominoplasty with breast reduction surgery, so called "mommy makeovers", the safety of this combined approach has been the subject of debate, with previous research yielding conflicting results. We evaluated the risk for complications and revision associated with adding abdominoplasty to bilateral breast reduction surgery.

Of the 1871 patients initially screened, 738 were included. 44 underwent a concomitant abdominoplasty procedure. Compared to the breast reduction alone group, patients with concomitant abdominoplasty were significantly older (47.5±9.9 vs. 42.8±13.2, p=0.004), had a higher BMI (28.1±4.4 vs. 25.8±3.1, p<0.001), and experienced longer operating room times (226±6 vs. 115±3 mins, p<0.001). In multivariate analysis, concomitant abdominoplasty did not increase the risk for breast-related (OR: 0.86 95%CI 0.43-1.7, p=0.668) or total complications (OR: 1.63, 95%CI 0.83-3.19, p=0.154). However, there was a trend towards an increased risk of breast revision (OR: 2.684, 95%CI 0.95-7.6, p=0.062) and a significantly increased risk of total revision (OR: 6.624, 95%CI 2.7-16.1, p<0.001). Moreover, patients with concomitant abdominoplasty experienced more follow-up visits (median: 4 vs. 3 visits, p=0.042).
In our single-center retrospective analysis, combining abdominoplasty with bilateral breast reduction did not increase the risk for breast, or total complications; however, it did increase the risk for total revisions.
Revolutionizing thread lifting: Evolution and techniques in facial rejuvenation.
J Cosmet DermatolThis review explores the utilization of thread lifting materials, distinct from traditional sutures, in aesthetic procedures. It aims to elucidate the varied composition, purpose, and performance of these slender materials.
The article contextualizes thread lifting materials by exploring their literal and material significance. The evolution of these materials is traced, emphasizing the preexistence of cog threads for tissue manipulation before their widespread adoption in plastic surgery.
Observations regarding the efficacy and longevity of absorbable versus non-absorbable threads are discussed, with a particular emphasis on the efficiency of high-quality absorbable cog threads.
The proliferation of thread lifting materials extends beyond PDO, necessitating consideration of multiple factors beyond duration when selecting threads for lifting procedures. This underscores the importance of comprehensive evaluation in choosing appropriate thread lifting materials.
The effects of fatty acids on psoriasis: A two-sample mendelian randomization study.
J Cosmet DermatolSome studies indicated an association between fatty acids (FA) and psoriasis. While definitive correlation between FA and psoriasis is still unclear. Therefore, our objective is to ascertain whether fatty acid levels are causally related to psoriasis using a Mendelian randomization approach.
We investigated the causal relationship between psoriasis and multiple types of FA by mendelian randomization. All data were acquired from Genome-Wide Association Study. We also performed additional analysis to assess the validity of the causal connection.
Our mendelian analysis suggests that n-3 fatty acid levels are associated with a lower risk of psoriasis. [IVW, OR/95% CI: 0.998/(0.997, 0.999), p (2.479 × 10-4)] Complementary analyses returned similar results, indicating consistency in our findings. No horizontal pleiotropy was found in our analysis. There was no indication of causal effects from other varieties of FA on psoriasis.
Our studies found that n-3 FA may lower the likelihood of developing psoriasis. We also need well-designed prospective studies and related large-scale, multicenter RCTs to confirm our findings.
