Objective To evaluate the efficacy and safety of fractional 1064 nm picosecond Nd:YAG laser (FPNYL) in the treatment of post‐acne erythema (PAE) of adult Chinese. Materials and methods A total of 22 patients received 1 session of treatment and were followed up at the eighth week. Primary outcomes were measured by the Clinician erythema assessment scale (CEAS). Secondary outcomes included a global aesthetic improvement scale (GAIS) and patients’ assessment of satisfaction on a five‐point scale. Pain scores and adverse effects were also evaluated. Results Twenty‐two patients with Fitzpatrick skin types III and IV were enrolled in the study and completed all treatments and follow‐up visits. The mean CEAS scores fell from 2.74 ± 0.80 to 1.95 ± 0.75 (p < 0.05). The mean GAIS of PAE improvement was 2.46 ± 0.68. Erythema percentile scores by VISIA increased from 32.63 ± 7.0 to 45.75 ± 11.45 (t = 5.442, p = 0). The patient satisfaction score was 1.86 ± 1.17. The pain scores were 3.27 ± 1.17 for the FPNYL treatment (varied from 2 to 6). There were moderate erythema and oedema, which last for 3.84 ± 0.78 days. There were overall 68.18% (15/22) patients who felt pruritus in different degrees and 27.27% patients who encountered acne eruptions (white head type). No scar, hyperpigmentation or hypopigmentation was found. Conclusion Treatment with fractional 1064 nm picosecond Nd:YAG laser is effective and safe for PAE of Chinese patients.

BackgroundThe demand for mammaplasty has increased in recent years, and infection remains one of the common and serious post‐operative complications. In this study, we analyzed the pathogen distribution and antibiotic susceptibility of breast plastic surgery infections, and compared the differences in pathogenic species between surgical procedures.MethodsThe number of each species was counted in the microbial samples of breast plastic surgery infections in Plastic Surgery Hospital of Chinese Academy of Medical Sciences from January 2011 to December 2021. The in vitro antibiotic sensitivity testing data were analyzed using WHONET 5.6 software. The surgical techniques, the period of infection, and other details were gathered in accordance with the clinical data.ResultsThere were a total of 42 cases included, and 43 different types of pathogenic bacteria, mostly gram‐positive bacteria, were found. CoNS (13/43) and Staphylococcus aureus (22/43) made up the majority. The most prevalent of the five Gram‐negative bacteria was Pseudomonas aeruginosa. Results of drug sensitivity tests indicate that S. aureus is highly sensitive to vancomycin, cotrimoxazole, and linezolid, whereas CoNS is highly sensitive to vancomycin, linezolid, and chloramphenicol. Both of these bacteria show high resistance to erythromycin and penicillin. Breast augmentation, breast reconstruction, and breast reduction surgery were the most frequently associated breast surgery procedures in this study with infections, with the highest number of infections occurring following breast augmentation with fat grafting, breast reduction surgery, and breast reconstruction with autologous tissue. Various breast plastic surgery procedures have different common pathogens of infection, but the most prevalent are CoNS and S. aureus. Additionally, the majority of the infections in this study were in the early stages.ConclusionsGram‐positive bacteria were the predominant cause of breast plastic surgery infections, and the types of infection strains, the period of infection onset, and the antibiotic susceptibility of prevalent strains varied between breast plastic procedures.

Facial esthetics is concerned with the harmonious beauty of the face. The skin, soft tissues, and bone tissues of the face degenerate as people age. Facial thread lift is a new minimally invasive esthetic technique that uses threads embedded within different tissue layers to reposition and support lax tissues. The authors report a 35-year-old female patient who developed an infection after undergoing facial thread lift, presenting with facial flushing and swelling, fever, and poor sleep, which was tested for Nocardiopsis dassonvillei infection. The patient was later cured by thread removal, local injection of 5-fluorouracil and triamcinolone acetonide. Postthreading infections have been documented in the past, but it is significant to note that, first, this patient's postinfection symptoms were distinct because she experienced both mild local symptoms and serious systemic symptoms, and second, the authors looked into a quick and efficient treatment option.
