Clinical Significance of Structural Variations in Breast Vasculature Evaluated via Three-Dimensional Computed Tomography Imaging.

Background: While alterations in the vasculature supplying the breast have been extensively recorded, there is no information on the direct breast branches of the axillary artery (AA). An elucidation of the direct breast branches may prove beneficial during mammoplasty.

Objective: This study sought to investigate the anatomical characterization of breast vasculature utilizing three-dimensional (3D) technology to establish an anatomical foundation for therapeutic operations.

Hypoxia-Preconditioned Adipose Stem Cell Exosomes Promote Adipose Graft Vascular Regeneration via miRNA-126.

Background And Objective: Adipose-derived mesenchymal stem cell-derived extracellular vesicles (ASCs-Exos) possess angiogenic potential, which can enhance the retention rate of fat grafts. Hypoxic preconditioning can augment their functionality. However, the optimal conditions for hypoxic preconditioning and the specific mechanisms by which it exerts its effects are not well defined.

Single-Cell RNA sequencing reveals mitochondrial dysfunction in microtia chondrocytes.

Microtia is a congenital malformation characterized by underdevelopment of the external ear. While chondrocyte dysfunction has been implicated in microtia, the specific cellular abnormalities remain poorly understood. This study aimed to investigate mitochondrial dysfunction in microtia chondrocytes using single-cell RNA sequencing.

Enhancing fat graft survival: thymosin beta-4 facilitates mitochondrial transfer from ADSCs via tunneling nanotubes by upregulating the Rac/F-actin pathway.

Autologous fat grafting is a widely used technique in plastic and reconstructive surgery, but its efficacy is often limited by the poor survival rate of transplanted adipose tissue. This study aims to enhance the survival of fat grafts by investigating the role of thymosin beta-4 (Tβ4) in facilitating mitochondrial transfer from adipose-derived stem cells (ADSCs) to adipocytes and newly formed blood vessels within the grafts via tunneling nanotubes (TNTs). We demonstrate that Tβ4 upregulates the Rac/F-actin pathway, leading to an increased formation of TNTs and subsequent transfer of mitochondria from ADSCs.

Single-Double-Single Barrel (1-2-1) Fibula Free Flap Design for Functional and Esthetic Brown Class III Mandibular Reconstruction.

This novel hybrid single-double-single barrel (1-2-1) design for fibula free flap reconstruction addresses the unique challenges presented by Brown Class III mandibular defects, which involve long-span defects at both bodies of the mandible and the chin. The importance of this design lies in its ability to overcome the limitations of traditional approaches in terms of mandible height and pedicle length, while optimizing both functional and esthetic outcomes.The technique utilizes a combination of single-double-single barrel fibula segments to achieve ideal esthetics and support for dental prosthesis across different areas of the mandible.

Incarceration is associated with higher mortality after trauma: An unreported health care disparity.

Background: While the United States has the highest incarceration rate worldwide, at nearly 1% of the adult population (more than 2 million people), insights regarding health disparities in this population remain limited. This retrospective cohort study represents the largest national database analysis of incarcerated trauma patients to date and investigates whether incarceration status is an independent risk factor for poor outcomes after trauma for US adults.

Methods: We analyzed data from the National Trauma Data Bank from 2017 to 2018.

Efficacy of ultrasound-guided suprazygomatic maxillary nerve block on emergence agitation and postoperative analgesia after septorhinoplasty: A prospective randomized trial.

Background And Aims: Emergence agitation (EA) is frequently encountered following nasal surgeries, and postoperative pain is a significant contributing element. We aimed to assess the role of suprazygomatic maxillary nerve (MN) block (SMB) guided by ultrasound (US) in lowering EA incidence and enhancing analgesia quality in septorhinoplasty cases.

Material And Methods: Sixty cases aged 18-60 years, of both genders, categorized by the American Society of Anesthesiologists (ASA) I-II and listed for septorhinoplasty, were randomized to receive general anesthesia (GA) with either no block (the control group) or combined with bilateral US-guided SMB (the SMB group).

Clinical and Pathological Analysis of Perianal Paget's Disease: A Case Report and Review of 89 Cases.

Background/aim: Perianal Paget's disease (PPD) is an intraepithelial invasion of the perianal skin that is frequently associated with anorectal carcinoma. Rectal canal carcinoma with Pagetoid spread (PS) is a relatively rare disease, and few reports on its outcomes are available. The relatively rare nature of this disease makes the development of treatment recommendations difficult.

Prevalence of lower extremity edema following inguinal lymphadenectomy: A systematic review and meta-analysis.

Background: Lower extremity lymphedema (LEL) can develop because of inguinal lymph node dissection in the treatment of gynecologic, genitourinary, and dermatological malignancies. To optimize patient counseling and patient selection for microsurgical interventions aimed at preventing or treating LEL, its prevalence and associated patient characteristics must be accurately documented. This systematic review and meta-analysis provides a comprehensive overview of literature on the reported prevalence of LEL in patients undergoing inguinal lymphadenectomy.

Use of the Superior Thyroid Artery as a Recipient Artery in Head and Neck Free Flap Reconstruction: Effects on Post-Operative Hypothyroidism.

Background: The superior thyroid artery (STA) as a recipient vessel in free flap reconstruction may theoretically impact thyroid function. This study aimed to assess whether the use of the STA has an adverse effect on thyroid function.

Methods: Retrospective review of 101 head and neck reconstructive cases.

Effective treatment of xanthelasma palpebrarum using Er:YAG laser.

Xanthelasma palpebrarum (XP), characterized by soft, yellowish plaque primarily on the eyelids, is often associated with lipid metabolism disorders. XP can cause aesthetic concerns that affect social interactions and requires careful treatment evaluations due to potential complications and associations with systemic conditions. We aimed to assess the efficacy of and recurrence rates with erbium:yttrium aluminum garnet (Er:YAG) laser therapy in the treatment of XP.

Defining the Zone of Acute Peripheral Nerve Injury Using Fluorescence Lifetime Imaging in a Crush Injury Sheep Model.

Purpose: Current technologies to define the zone of acute peripheral nerve injury intraoperatively are limited by surgical experience, time, cumbersome electrodiagnostic equipment, and interpreter reliability. In this pilot study, we evaluated a real-time, label-free optical technique for intraoperative nerve injury imaging. We hypothesize that fluorescence lifetime imaging (FLIm) will detect a difference between the time-resolved fluorescence signatures for acute crush injuries versus uninjured segments of peripheral nerves in sheep.

Surgical excision of symptomatic lateral band snapping syndrome in small finger proximal interphalangeal joint.

Lateral band snapping syndrome can be a debilitating condition involving the proximal interphalangeal (PIP) joint of the fingers. Although rare, it is thought to occur due to disruption of the finger extensor mechanism allowing inappropriate subluxation of the lateral bands over the PIP joint, leading to mechanical and painful symptoms.Here, we describe a woman in her early 40s with a painful, snapping PIP joint secondary to a work-related injury.

Systemic siliconomas following breast implant rupture.

We report a case of a woman in her late 40s with a history of breast implant surgery following breast cancer treatment. She presented with asymmetrical breast enlargement, palpable contralateral axillary lymph nodes and cutaneous nodules on both forearms. In addition, imaging evaluation revealed intracapsular implant rupture, ipsilateral internal mammary enlarged lymph nodes and multiple mediastinal lymphadenopathies.

Hand therapy utilization following digital flexor tendon repair: Trends, timing, predictive factors, and association with reoperation.
