Background Lower eyelid blepharoplasty is one of the most popular aesthetic procedures. Electrocautery provides a hemostatic benefit for skin incision; however, its effect on scar cosmesis remains unclear, particularly in Asian skin types. We compared the Colorado needle electrocautery (pure-cutting mode) versus the traditional scalpel in terms of...

Cellular senescence plays a role in the development of aging-associated degenerative diseases. Cell therapy is recognized as a candidate treatment for degenerative diseases. To achieve the goal of cell therapy, the quality and good characteristics of cells are concerned. Cell expansion relies on two-dimensional culture, which leads to replicative s...

Cell-based therapy has become an achievable choice in regenerative medicines, particularly for musculoskeletal disorders. Adipose-derived stem cells (ASCs) are an outstanding resource because of their ability and functions. Nevertheless, the use of cells for treatment comes with difficulties in operation and safety. The immunological barrier is als...

Immunomodulatory properties of mesenchymal stem cells are widely studied, supporting the use of MSCs as cell-based therapy in immunological diseases. This study aims to generate cell-free MSC extract and improves their immunomodulatory potential. Intracellular extracts were prepared from adipose-derived stem cells (ADSC) spheroid via a freeze-thawi...

Background Large-scale production of mesenchymal stromal cells is essential for sufficient therapeutic doses in regenerative medicine. However, long-term cultivation encounters limited cell growth and cellular aging. Therefore, an alternative cell culture approach that promotes proliferation and attenuates cell senescence is required. Human platele...

Unlabelled: Upper eyelid blepharoplasty is a popular aesthetic surgery. Electrocautery provides a hemostatic benefit for skin incision; however, its effect on scar cosmesis remains unclear, especially in Asian skin types. We aimed to compare the Colorado needle electrocautery pure cutting mode and the traditional scalpel to determine their efficac...

Background: Maxillofacial fractures are a common cause of visits to emergency department, accounting for more than 400,000 annual visits in the United States. Gold standard diagnostic tool is conventional computerized tomography (CT) or 3DCT reconstruction. However, the disadvantages of CT are radiation exposure, unavailable in some hospital and e...

Background Bleeding, a common intraoperative complication of liposuction, often causes pain and discomfort during recovery. Owing to the vasoconstrictive effect of adrenaline in the tumescent solution, bleeding can be reduced in liposuction; however, reports of postoperative bleeding persist. Moreover, cold temperatures also possess a vasoconstrict...

Background Knowledge of the location of supraorbital nerve is essential to perform supraorbital endoscopic surgery, regional nerve block, and nerve decompression in the treatment of migraine. This study discusses the emergence routes of supraorbital nerve as well as a systematic literature review on previous anatomical studies. This comparative ana...

Background: Orbital floor fracture is typically present with peri-orbital ecchymosis, subconjunctival hemorrhage, enophthalmos and diplopia. The goals of reconstruction are to restore the volume and shape of the orbital cavity with autogenous or alloplastic materials. However, no gold standard exists for orbital implants to treat orbital floor frac...

Atypical lipomatous tumor/well-differentiated liposarcoma (ALT/WDLPS) is a locally aggressive mesenchymal neoplasm composed either entirely or partly of an adipocytic proliferation showing at least focal nuclear atypia in both adipocytes and stromal cells. ALT most frequently occurs in deep soft tissue of proximal extremities (thigh and buttock) an...

We present the case of an 18-year-old man who was referred to our department with a suspected tumor in the right orbital region, which caused exophthalmos due to its pressure effect. Preoperative CT imaging revealed an expansile ground-glass appearance of bone mass, with sclerotic bone on the right frontal bone (right superior orbital wall). There...

Background: Burn injuries are burdensome to the public health system. Hypertrophic scars are the most common undesirable sequelae associated with burn scar contracture, resulting in reduced hand function. This study compared 2 different forms of silicone combined with pressure garment (PG) to determine the efficacy in hypertrophic scar prevention...

We present the case of a 48-year-old woman with a chronic ulcer with bony erosion over the right chest wall who had undergone adjuvant chemoradiotherapy for right breast cancer 18 years previously. Preoperative computed tomography revealed a large soft tissue ulcerative lesion with bony destruction of the anterolateral aspect of the right fifth and...

Background Beautiful upper eyelids can make one feel more attractive and confident. However, the definition of a beautiful upper eyelid in Orientals is still not defined. The aim of this study was to define the most beautiful upper eyelids in Orientals. Methods Participants, who met the inclusion criteria such as Asian ethnic, ages between 18 and...

Background: Liposuction is the most common aesthetic surgical procedure performed globally. Some of the patients with normal weight who seek liposuction may suffer from body dysmorphic disorder (BDD). Leptin, which is mainly produced by adipose tissue, may be associated with this condition. The aim of this study was to determine the prevalence of...

Primary breast angiosarcoma is an extremely rare tumor type (0.05% of primary breast cancers) for which diagnosis can be difficult. They arise within the breast parenchyma and typically present as a breast mass. Here, we present the case of a 30-year-old female with spontaneous hypervascular skin on her right breast with progressive enlargement pre...

Lymphatic cyst is a collection of lymphatic fluid with an epithelial lining which can either represent lymphatic malformations or may occur after trauma or operation. Idiopathic lymphatic cyst of the thigh in adulthood is extremely rare. We report a case of a 27-year-old Thai female presented with a rapidly growing mass over her right thigh. The ma...

Background: Aloe vera has been used to treat wounds since ancient times. However, the efficacy of Aloe vera for burns and split-thickness skin graft (STSG) donor sites are inconclusive. Methods: A double-blind, randomized, controlled trial was conducted. Patients who underwent STSG harvesting from the thigh were included. STSG donor sites were d...

Alveolar soft part sarcoma (ASPS) is a very rare sarcoma, report <1% of all soft tissue tumor. Majority of cases were young adult and tumor occurred in lower extremities and trunk. Here, we present a case of 53-year-old Thai female with rapidly glowing mass over her right forearm. The magnetic resonance imaging scan demonstrated a hypervascular mas...

Background: Keloids have been one of the most concerning problems in cosmetic surgery. Current treatments still provide unpredictable outcomes. Interestingly, one molecular study of Botulinum Toxin A (BTXA) has found the inhibitive effect of fibroblast growth factor (TGF-β), which explain the mechanism of keloid formation. Objective: To study th...

Squamous cell carcinoma (SCC) of the oral tongue and floor of mouth are the most common head and neck cancers. Regional metastasis of SCC is most likely found at the cervical lymph node. Size and characteristics of pathologically suspicious lymph nodes are related to the aggressiveness of the primary tumor: The objective of this study is to analyze...

Chronic wound is a common clinical condition and often cause treatment problems. This is because chronic wound usually require extended treatment period, which result in high hospital cost. The treatment of chronic wound depends on the type of wound, the cause of wound, and the physical status of patient. Vacuum dressing has become a standard treat...
