Evaluating Access and Outcomes in Gender-affirming Breast Augmentation: A Comparative Study of a County Hospital and an Academic Center.

Background: Research on the diverse patient population undergoing gender-affirming breast augmentation remains scarce. We compared patients undergoing this procedure at San Francisco General Hospital (ZSFG), a county hospital, and the University of California, San Francisco (UCSF), an academic medical center.

Methods: This was a retrospective cohort study of patients who underwent primary gender-affirming breast augmentation at ZSFG (August 2019 to June 2023) and UCSF (March 2015 to June 2023).

Surgical Treatment of Granulomatous Breast Deformities Caused by Injection of Foreign Substances in Transgender Women: A Case Series and Algorithm.

Summary: Despite potentially devastating complications, free foreign substance injections for feminizing breast augmentation remain common among transgender women. To date, the literature regarding surgical treatment of these deformities among transgender women remains limited. The authors present a case series of transgender women presenting for surgical management of granulomatous breast deformities secondary to free foreign substance injections between January of 2016 and February of 2020.

Management of soft-tissue coverage of open tibia fractures in Latin America: Techniques, timing, and resources.

Purpose: This study examined soft-tissue coverage techniques of open tibia fractures, described soft-tissue treatment patterns across income groups, and determined resource accessibility and availability in Latin America.

Methods: A 36-question survey was distributed to orthopaedic surgeons in Latin America through two networks: national orthopaedic societies and the Asociación de Cirujanos Traumatólogos de las Américas (ACTUAR). Demographic information was collected, and responses were stratified by income groups: high-income countries (HICs) and middle-income countries (MICs).

Composite Vascularized Autograft Elbow Transplant: A Case Report.

Case: A 37-year-old man presented with an absent right elbow joint secondary to trauma, subsequent ankylosis, total elbow arthroplasty (TEA), and TEA explantation after infection. The patient also had a contralateral complete brachial plexus injury, but an intact elbow joint. Given that the patient had a functional right hand/wrist, composite vascularized autograft elbow transplant was performed from left to right upper extremity.

The Impact of Inadequate Soft-tissue Coverage following Severe Open Tibia Fractures in Tanzania.

Unlabelled: Managing lower extremity fractures complicated by large soft-tissue defects is challenging for surgeons in low- and middle-income countries, and long-term quality of life (QOL) for these patients is unclear.

Methods: We examined QOL, surgical complications, and longitudinal outcomes in 10 patients with Gustilo-Anderson Classification Type IIIB open tibia fractures seen at an orthopedic institute in Tanzania, from December 2015 to March 2017. Patients completed follow-up at 2-, 6-, 12-, 26-, and 52-week time points, and returned for qualitative interviews at 2.

Knowledge deficits and barriers to performing soft-tissue coverage procedures: An analysis of participants in an orthopaedic surgical skills training course in Mexico.

Background: An increasing number of traumatic injuries in low- and low-middle-income countries (LICs/LMICs) have coexisting injuries requiring soft-tissue coverage (flaps). Yet, there is a lack of subspecialty care and flap training in Latin America. This study assesses the effectiveness of a surgical skills training course in improving rotational and free flap knowledge and identifies barriers to performing these types of flaps.

Barriers to Performing Soft Tissue Reconstruction Procedures among Orthopedic Surgeons in Low- and Middle-income Countries: Results of a Surgical Skills Training Course.

Background: Appropriate management of soft tissue injury associated with orthopedic trauma is challenging in low- and middle-income countries (LMICs) due to the lack of available reconstructive surgeons. The Surgical Management and Reconstructive Training (SMART) course teaches orthopedic surgeons reconstructive techniques aimed at improving soft tissue management. This study aims to identify additional barriers to implementing these techniques for surgeons in LMICs who have attended SMART courses.

Obstacles to the Care of Patients With Multicomponent Volar Wrist Lacerations at a County Hospital.

Background: Multicomponent volar wrist lacerations of "spaghetti wrist" injuries are devastating injuries of the upper extremity. These patients require long-term commitment to rehabilitation. Patients presenting to our county hospital represent a unique and complex patient population in terms of psychosocial considerations.

Hueston revisited: use of acellular dermal matrix following fasciectomy for the treatment of Dupuytren's disease.

Various surgical treatment modalities have been advocated for the treatment of Dupuytren's disease. However, recurrence following surgical treatment of Dupuytren's disease remains a common problem. Previous studies have demonstrated lower recurrence rates with use of a full-thickness skin graft.

Use of face masks by non-scrubbed operating room staff: a randomized controlled trial.

Background: Ambiguity remains about the effectiveness of wearing surgical face masks. The purpose of this study was to assess the impact on surgical site infections (SSIs) when non-scrubbed operating room staff did not wear surgical face masks.

Methods: Eight hundred twenty-seven participants undergoing elective or emergency obstetric, gynecological, general, orthopaedic, breast or urological surgery in an Australian tertiary hospital were enrolled.

A case of unilateral coronal synostosis in a child with craniofacial microsomia.

Craniofacial microsomia is a congenital malformation complex associated with a wide array of craniofacial and extracraniofacial anomalies. Frontal plagiocephaly has been shown to occur in approximately 5% to 12% of patients with craniofacial microsomia. The etiology of craniofacial microsomia-associated frontal plagiocephaly is unclear; of the cases described in the literature, all but one had physical findings suggestive of deformational plagiocephaly.

Primary sequence independence for prion formation.

Many proteins can adopt self-propagating beta-sheet-rich structures, termed amyloid fibrils. The [URE3] and [PSI+] prions of Saccharomyces cerevisiae are infectious amyloid forms of the proteins Ure2p and Sup35p, respectively. Ure2p forms prions primarily as a result of its sequence composition, as versions of Ure2p with the prion domain amino acids shuffled are still able to form prions.

Lentiviral gene therapy with platelet-derived growth factor B sustains accelerated healing of diabetic wounds over time.

The treatment of diabetic wounds is a formidable clinical challenge. In this study, lentiviral vectors carrying the human platelet-derived growth factor B (PDGF-B) gene were used to treated diabetic mouse wounds. Full-thickness 2.

HOX gene clusters are hotspots of de novo methylation in CpG islands of human lung adenocarcinomas.

CpG island methylation results in the silencing of the associated gene and is an important step in tumorigenesis. Following a comprehensive isolation of CpG islands that were methylated in human lung adenocarcinoma, we found that in cancer cells de novo CpG island methylation generally occurred in a sporadic manner. However, some methylated CpG islands appeared to cluster in discrete chromosomal regions.

A comprehensive catalog of CpG islands methylated in human lung adenocarcinomas for the identification of tumor suppressor genes.

CpG island methylation is an important mechanism in gene silencing and is a key epigenetic event in cancer development. As yet, the number and identities of the genes that are inactivated in cancer cells has not been determined. In order to address this issue, we have performed a comprehensive isolation of CpG islands that are methylated in human lung adenocarcinomas.
