Obstructive Sleep Apnea in Patients With Oral and Oropharyngeal Cancer Undergoing Free Flap Reconstruction: A Longitudinal Study With Computed Tomography.
[BACKGROUND] Obstructive sleep apnea (OSA) often worsens in head and neck cancer patients post-treatment. Its relationship with airway morphology after free flap reconstruction in oral/oropharyngeal cancer (OOC) remains unclear. This study …

The Effectiveness of Botulinum Toxin Injection for Cricopharyngeal Dysfunction-Related Dysphagia in Nasopharyngeal Carcinoma Patients.
To evaluate the effectiveness of botulinum toxin injection in improving swallowing function in patients with cricopharyngeal muscle dysfunction (CPMD) following radiotherapy for nasopharyngeal carcinoma (NPC). Cohort study. Outpatients with…

A Novel Six-Point Supraperiosteum Injection with Calcium Hydroxyapatite for Jawline Refining and Facial Anti-aging in Asian Patients.
[BACKGROUND] Supraperiosteal injection by calcium hydroxyapatite (CaHA) fillers is an efficient treatment for facial rejuvenation to achieve bony recontouring, facial augmentation and lifting. However, a safe and efficient injection techniq…

Quantitative Assessment of New Frontiers in Dermatochalasis and Periorbital Hyperpigmentation Treatment: The Role of Cross-Linked Porcine Collagen.
[BACKGROUND] Collagen dermal fillers have shown efficacy in addressing age-related changes in facial appearance. However, their potential in rejuvenating the periorbital region remains unexplored. The aim of this study was to evaluate the e…

Acute Paraplegia Following Spinal Anesthesia in a Patient With Unrecognized Thoracic Ossification of the Posterior Longitudinal Ligament and Spinal Stenosis: A Case Report.
Spinal coning is a rare complication in spinal anesthesia that results in acute neurological deterioration. It occurs when a pre-existing spinal stenosis alters the CSF flow, creating a high-pressure area beneath the stenosis. The introduct…

A Comparison of the Use of Two-Dimensional and Three-Dimensional Visualization Systems by Novice and Experienced Microsurgeons in Microsurgical Vessel Anastomosis: An Analysis Using the Chicken Model.
[BACKGROUND] Various studies have discussed the benefits of applying three-dimensional (3D) techniques, specifically its advantages with respect to ergonomics, feasibility, and the rate of learning achievable in microsurgery training. Howe…

Impact of free flap reconstruction on obstructive sleep apnea in patients with oral and oropharyngeal cancer.
[OBJECTIVE] Little is known about the association between obstructive sleep apnea (OSA) and oral and oropharyngeal cancers (OOCs). This study aims to investigate the incidence and severity of OSA in patients with OOCs before and 6 months af…

Cephalometric analysis following combined Sub-SMAS hyaluronic acid injection and subdermal and supraperiosteal poly-L-lactic acid injections in Asian women.
[BACKGROUND] The aging face is characterized by skin laxity and volume loss. Attenuation of facial retaining ligaments significantly contributes to skin sagginess and soft tissue volume loss. [AIMS] We designed a prospective cohort study t…
- Conceptual framework for trainers in a microsurgical project: Attendee-oriented and structured learning using a nonliving animal model.

Modified Clavien-Dindo Classification and Outcome Prediction in Free Flap Reconstruction among Patients with Head and Neck Cancer.
Because of limitations caused by unique complications of free flap reconstruction, the Clavien-Dindo classification was modified to include grade "IIIc" for "partial or total free flap failure." From 2013 to 2018, 116 patients who had under…

Lifespan Extension and Sustained Expression of Stem Cell Phenotype of Human Breast Epithelial Stem Cells in a Medium with Antioxidants.
We have previously reported the isolation and culture of a human breast epithelial cell type with stem cell characteristics (Type I HBEC) from reduction mammoplasty using the MSU-1 medium. Subsequently, we have developed several different n…

Delayed active bleeding after radical evacuation of injected polyacrylamide hydrogel and immediate implant based breast reconstruction.
[BACKGROUND] Polyacrylamide hydrogel (PAAG) was used in breast augmentation surgery in China during 1997-2006. Its application has led to increasing complications such as localized lumps, asymmetry, diffuse stiffness, infections, and locali…

Loss of anti-proliferative effect of all-trans retinoic acid in advanced stage of breast carcinogenesis.
[BACKGROUND] Mechanisms by which the inhibitory effect of retinoic acid on tumor growth is attenuated as tumors progress to more advanced stages are unclear. [MATERIALS AND METHODS] This study utilizes a novel cell culture system of human …
-
Evaluation of sphinganine and sphingosine as human breast cancer chemotherapeutic and chemopreventive agents.
No comparative study of the effects of sphingolipid metabolites on proliferation and differentiation in normal human breast epithelial cells versus stem cells and tumorigenic cells has been reported. The purpose of this study was to evaluat…
-
High susceptibility of a human breast epithelial cell type with stem cell characteristics to telomerase activation and immortalization.
We have recently characterized two types of normal human breast epithelial cells (HBECs) from reduction mammoplasty. Type I cells express estrogen receptor, luminal epithelial cell markers, and stem cell characteristics (i.e., the ability t…
-
Expression of estrogen receptors in a normal human breast epithelial cell type with luminal and stem cell characteristics and its neoplastically transformed cell lines.
Although approximately two-thirds of breast cancers are estrogen receptor (ER)-positive, only a small proportion of epithelial cells in the mammary gland express the ER. The origin of the ER-positive breast cancers is unknown. Recently, we …
-
Growth requirements and neoplastic transformation of two types of normal human breast epithelial cells derived from reduction mammoplasty.
A chemically defined culture medium was developed to support the growth of two distinctly different types of normal human breast epithelial cells (HBEC) derived from reduction mammoplasty. Type I cells expressed luminal epithelial cell mark…
-
Two types of normal human breast epithelial cells derived from reduction mammoplasty: phenotypic characterization and response to SV40 transfection.
A culture method to grow two morphologically distinguishable normal human breast epithelial cell types derived from reduction mammoplasty has been developed. Type I cells were characterized by a more variable cell shape, smooth cell colony …
