Actionable Gene Alterations Identified in Patients With Malignant Melanoma by Targeted Sequencing in Japan.

Purpose: Precision medicine plays an important role in the treatment of patients with advanced melanoma. Despite its high incidence in White patients, advanced melanoma is rare in Asian countries, hampering prospective clinical trials targeting the Asian population. This retrospective study aimed to elucidate the real-world molecular diagnoses and outcomes of Japanese patients with melanoma using comprehensive genome profiling (CGP).

Exploring the Unique Properties and Superior Schwann Cell Guiding Abilities of Spider Egg Sac Silk.

Spider silk (SPSI) is a promising candidate for use as a filler material in nerve guidance conduits (NGCs), facilitating peripheral nerve regeneration by providing a scaffold for Schwann cells (SCs) and axonal growth. However, the specific properties of SPSI that contribute to its regenerative success remain unclear. In this study, the egg sac silk of is investigated, which contains two distinct fiber types: tubuliform (TU) and major ampullate (MA) silk.

Bacteria in hypertrophic scars promote scar formation through HSBP1-mediated autophagy.

Bacterial colonisation in hypertrophic scars (HSs) has been reported, yet the precise mechanism of their contribution to scar formation remains elusive. To address this, we examined HS and normal skin (NS) tissues through Gram staining and immunofluorescence. We co-cultured fibroblasts with heat-inactivated Staphylococcus aureus (S.

Risks of Autologous Abdominal Free Flap Breast Reconstruction in Patients With Elevated Body Mass Index.

Background: Obesity is widely recognized as a significant risk factor for postoperative complications of breast reconstruction. Despite extensive research, there remains a lack of consensus regarding the specific complications and outcomes experienced by patients with obesity who undergo deep inferior epigastric perforator (DIEP) flap reconstruction. To provide a clearer understanding of the challenges faced by patients with obesity, we present a single-center outcome analysis of individuals who underwent DIEP flap reconstruction.

Is Topical Tranexamic Acid Effective in Reducing Hematoma and Seroma in Breast Surgery? A Systematic Review and Meta-analysis.

Background: Postoperative fluid-related complications, such as hematoma and seroma formation, are common concerns in breast surgery, adversely affecting surgical outcomes and patient recovery. Topical tranexamic acid (TXA) has emerged as a promising intervention to minimize bleeding while reducing systemic adverse effects linked to intravenous administration. However, evidence on the efficacy of topical TXA in breast surgery remains sparse.

Chimeric Osteocutaneous Free Flap Solution to Variation in Vascular Anatomy.

When squamous cell carcinoma necessitates mandibular resection, the resultant defect can be complex. An osteocutaneous fibula free flap is an effective reconstruction option, typically supplied by the peroneal artery for both the fibula and skin flap. In this case report, an anatomical variation was found: the skin paddle was supplied by soleus musculocutaneous perforators of the posterior tibial artery, whereas the fibula was supplied by the peroneal artery.

Vascularized Iliac Crest Bone Graft for the Reconstruction of Anterior Vertebral Corpus Defects: A Literature Review and Cadaveric Feasibility Study.

Background: Vertebral body defects pose a significant challenge in spinal reconstructive surgery. Compression fractures of the vertebral corpus are typically treated with vertebral augmentation procedures. There are significant risks associated with the introduction of foreign material in the spine, including infection and pseudarthrosis.

"Nip and Tuck": Training the Next Generation of Aesthetic Plastic Surgeons.

The demand for aesthetic surgery continues to increase, and it is therefore essential to ensure that the next generation of plastic surgeons are adequately trained. We propose a safe method in aesthetic training in abdominoplasty and facelift, utilizing free deep inferior epigastric perforator (DIEP) flap and parotidectomy for training aesthetic procedures. The trainees' focus differed between the 2 procedures.

Bifurcating Method for Subcutaneous Indwelling of Nonabsorbable Threads.

Subcutaneous indwelling of nonabsorbable threads for tissue fixation and tension reduction is often used in plastic surgery and is applied in breast reduction surgery, umbilicoplasty, and in frontalis muscle lifting for congenital ptosis. However, in a few cases, exposure of the indwelling thread necessitates its removal. Exposure of the indwelling threads mostly occurs due to exposure of the knots.

Artificial Intelligence Scribe and Large Language Model Technology in Healthcare Documentation: Advantages, Limitations, and Recommendations.

Artificial intelligence (AI) scribe applications in the healthcare community are in the early adoption phase and offer unprecedented efficiency for medical documentation. They typically use an application programming interface with a large language model (LLM), for example, generative pretrained transformer 4. They use automatic speech recognition on the physician-patient interaction, generating a full medical note for the encounter, together with a draft follow-up e-mail for the patient and, often, recommendations, all within seconds or minutes.

Matching Into Integrated Plastic Surgery: The Impact of USMLE Step 1 Transition to Pass/Fail: Did the 2019 Predictions Come True in 2024?

Background: The first class of integrated plastic surgery residency applicants with pass/fail (P/F) step 1 assessments occurred during the 2023-2024 Match cycle. This study analyzes the results of a 2024 postmatch survey to program directors (PDs) regarding the impact of the conversion to P/F step 1 scoring and compares the results to the 2019 survey that attempted to predict how this conversion would influence decision-making when it was initially announced.

Methods: A 26-item survey evaluating PDs' perspectives on applicant characteristics and the application process following P/F step 1 scoring was distributed March 2024.

Managing blood requirement in a rare P-null phenotype patient during the COVID pandemic in a resource-limited setting.

We report the case of a 5-year-old girl with a rare P-null phenotype who presented for a neurosurgical procedure at our center. The case is unique as this patient was one of the two P-null phenotype cases reported in India and we report how we could successfully arrange a rare blood unit for her. As it was challenging to find a donor for her, autologous blood was collected.

Phellodendrine inhibits oxidative stress and promotes autophagy by regulating the AMPK/mTOR pathway in burn sepsis-induced intestinal injury.

Intestinal injury is an important complication of burn sepsis with limited therapeutic choices. Phellodendrine is a promising compound for gastrointestinal inflammatory diseases and is extracted from the traditional Chinese medicine phellodendron bark. The study aimed to explore the role of phellodendrine against oxidative stress and autophagy in burn sepsis-induced intestinal injury.

A novel surgical technique of use of the Goligher self-retaining retractor for microvascular anastomosis in reconstruction after minimally invasive mastectomy.

In recent years, minimally invasive breast surgery (MIBS) has revolutionized breast cancer treatment, allowing for preservation of aesthetic outcomes while ensuring oncological safety. However, this has created a new challenge in maintaining optimal visualization and dexterity during microvascular anastomosis which is critical for successful autologous tissue reconstruction. Traditional retractors often limit maneuverability, potentially impacting the outcomes of anastomotic procedures.

Research progress on quercetin in improving the survival rate of random skin flap.

Random skin flap transplantation is critical in wound repair, organ reconstruction and cosmetic surgery, yet skin flap necrosis remains a common and challenging issue. Quercetin, a flavonoid abundant in various plants, exhibits anti-inflammatory, antioxidant, and other beneficial pharmacological effects. Recent studies suggest quercetin can improve random skin flap survival by modulating inflammation, reducing oxidative stress, and promoting angiogenesis.
