endogenous PKG and functionally implicates the role of RyR2 phosphorylation.The generation of breast implant-associated anaplastic large-cell lymphoma (BIA-ALCL) is closely associated with textured implants. The phenotype of BIA-ALCL cells is well examined, but its cell of origin remains unknown. Here we investigate what types of T cells are recruited and differentiated in the surrounding capsules and tissues as a consequence of continuous contact with a textured surface.

Capsule and pericapsule tissues were recovered from patients who had textured or smooth tissue expanders (TEs). These samples were enzymatically digested, and T cells in the samples were analyzed using flow cytometry. Peripheral blood mononuclear cells from the same donors were utilized as a control.

Effector memory CD4

T cells predominantly infiltrated capsules and tissues without apparent differences between textured and smooth TEs. In these effector memory CD4

T cells, CD4

resident memory T cells were generated by smooth TEs but not by textured TEs. However,

mRNA expression is higher in the CD69

effector memory CD4

T cells than in the CD69

ones.

Textured and smooth TEs differentially recruit and/or differentiate T cells in situ.

There have been no other reports of CEH occurring after implant removal. Furthermore, this is also the first case of a CEH that developed bilaterally in the breasts; most reported cases are of a unilaterally developed CEH. A CEH reportedly develops after a long period of time following trauma or surgery. If surgeons encounter an expanding tumor emerging from regions with such a history, they must consider the presence of a CEH even after implant removal, as in the present case. Hematomas caused by trauma or surgery are usually absorbed or are replaced with fibrous tissue. In rare cases, they can chronically increase as CEHs. Herein, we report a case of a CEH that occurred in both breasts approximately 20 years after silicone breast implant removal.The second victim phenomenon is the distress felt by healthcare providers after a medical error. Although the phenomenon is a significant risk factor for burnout, little has been written about it in surgery, especially among residents.

After institutional review board approval, a 27-question anonymous online survey was sent to plastic surgery residents throughout the United States, and to residents from all surgical specialties at our institution, for a total of 435 residents. Residents were asked to describe any adverse events they had experienced, and subsequent emotional sequelae.

The survey was returned by 125 residents (response rate 28.7%), of whom 53 were plastic surgery residents (42.4%) and 72 were from other surgical specialties (57.6%). In total, 110 (88%) described having been part of a medical error. An estimated 74 residents (34 from plastic surgery, 40 from other surgical specialties) provided a detailed description of the event. Sixty-four of them (86.5%) had subsequent emotional sequelae, most commonly guilt, anxiety, and insomnia. Only 24.3% of residents received emotional support. They rated other residents as the most important source of support, followed by faculty members and then family/friends.

The second victim phenomenon seems to be common among surgical residents. The most important source of support for affected residents in our cohort was other residents. Given these findings, institutions should focus on fostering camaraderie among residents, building effective second victim response teams and training peer support specialists.

Research has also become more diverse in those who conduct studies and those who participate in them. Fittingly, surgeons who produce prominent research are likely to come from diverse backgrounds. This study was designed to analyze the diversity of authorship in peer-reviewed plastic surgery journals.

Using the Web of Science database, the authors identified the 100 most-cited articles from the highest-impact plastic surgery journals from January 2010 to December 2020. Author, institutional, and topic information was collected.

There was an average of 5.6 authors on the top 100 articles, of which 96.1% involved collaboration and 75.7% mixed-gender authorship. The average number of affiliations was 2.1, of which 51.5% involved cross-institutional collaboration, 12.6% came from both domestic and international institutions, 30.1% involved multiple specialties, and 10.7% came from both academia and private practice. Having both domestic and international authors was found to be most predictive of more citations on multiple regression, with year as a nonconfounding variable (

< 0.05), followed by mixed-gender authorship (

< 0.10).

Given that elevation of the soft tissue envelope in a continuous subperiochondrial-subperiosteal dissection preserves soft tissues, vessels, nerves, and lymphatics, this procedure may result in faster healing time and less swelling and scarring. However, the technique requires a learning phase and can be challenging to perform because it typically requires meticulous dissection under surgical loupes. The dissection may thus be time-consuming and a burden for surgeons, especially in secondary rhinoplasty cases. Further, the potential risk of musculoskeletal discomfort and injury to the surgeon should not be overlooked; consideration for surgical ergonomics is needed to prevent injuries and enhance surgical performance. To address these issues, we propose the use of a surgical microscope for subperiochondrial-subperiosteal dissection in preservation rhinoplasty. A microscope enables clear visualization of the surgical field and allows surgeons to make precise and delicate manipulation maneuvers. Moreover, it may also enable surgeons to maintain an ideal ergonomic posture and neutral positioning of their joints, thereby reducing physical strain. A surgical microscope may thus be a useful tool for subperiochondrial-subperiosteal dissection by providing clear visualization of the surgical field and improved surgical ergonomics for surgeons.The impact of previous radiotherapy on free flap outcome is still a subject of debate. Clinical investigations have come to divergent conclusions and the true effect of radiotherapy (XRT) on flap survival is not definitely known. Most studies investigating the factor often have their methodological limitations such as lack of statistical power as a consequence of the overall low failure rates together with few irradiated cases. This study will attempt to address the question whether previous radiotherapy is associated with a significantly higher incidence of flap failure or not.

A systematic review and meta-analysis were conducted in concordance with the PRISMA protocol using the PubMed database. Fixed-effect and random-effect models were applied to obtain the odds ratio of total flap failure and partial flap failure between radiation and nonradiation groups. Statistical heterogeneity and publication bias were assessed and forest plots and funnel plots were constructed for graphic illustration.

A total of 43 studies were included for qualitative and quantitative analysis involving 18,776 flaps in 17,532 patients. Patients with preoperative XRT were significantly associated with an increased risk for total (odds ratio fixed = 1.675, 95% confidence interval [CI] = 1.405-1.996,

< 0.001) and partial free flap failure (odds ratio fixed = 2.161, 95% CI = 1.472-2.172,

< 0.001).

The study suggests that preoperative radiotherapy is associated with an increased risk for total and partial free flap failure. Further studies are needed to investigate the effect of total XRT dose and time after radiation on free flap outcome.

A 48-year-old woman with chronic bilateral severe blepharoptosis of 10 years duration is presented, whose neurological investigations excluded myasthenia gravis. The patient was preliminarily diagnosed with chronic progressive external ophthalmoplegia. selleck The levator excursion was negligible, and a frontalis suspension procedure was considered using a conventional autogenous fascia lata graft. An optimal outcome was achieved with over 16-years follow-up. Although the patient was healthy otherwise upon first presentation, 10 years later, she developed other neurologic manifestations, including dysphagia and oral dryness. The fact that blepharoptosis did not recur over the years in this case differentiates an oculo-pharyngeal type of muscular dystrophy in this patient from other types and from the more frequent condition of chronic progressive external ophthalmoplegia.Existing disparities in the perception of scars between patients and practitioners can translate into undesirable physical and psychological outcomes. An understanding of the determinants of surgeons' perceptions on the importance of scar cosmesis is a first step toward bridging this gap.

In an online survey, surgeons were asked about the extent to which various patient and technical factors affect the importance of scar cosmesis. Additional data were obtained on surgeon characteristics, including their specialty, gender, years of experience, and work sector to investigate potential relationships.

A total of 303 responses were obtained from surgeons across six specialties. Based on the survey, the importance of scar cosmesis was rated highest among plastic surgeons and obstetricians and gynecologists, and lowest among orthopedic and vascular surgeons. Compared with surgeons in private practice, publicly employed surgeons' rating of the importance of cosmesis was lower. The patient's request for a cosmetic Greater alignment between the priorities of surgeons and patients may manifest in objective and subjective improvements in patient's scars and well-being.This systematic review aimed to update the management of sleep bruxism (SB) in adults, as diagnosed using polysomnography (PSG) and/or electromyography (EMG). Management methods covered were oral appliance therapy (OAT) with stabilization splints, cognitive-behavioral therapy (CBT), biofeedback therapy (BFT), and pharmacological therapy. A comprehensive search was conducted on MEDLINE, Cochrane Library, and Web of Science up to October 1st, 2021. Reference list searches and hand searches were also performed by an external organization. Two reviewers for each therapy independently performed article selection, data extraction, and risk of bias assessment. The reviewers resolved any disagreements concerning the assortment of the articles by discussion. Finally, 11, 3, 14, and 22 articles were selected for each therapy. The results suggested that OAT tended to reduce the number of SB events, although there was no significant difference compared to other types of splints, that the potential benefits of CBT were not well supported, and that BFT, rabeprazole, clonazepam, clonidine, and botulinum toxin type A injection showed significant reductions in specific SB parameters, although several side effects were reported.
