Septal perforation repair using costal chondro-perichondrial graft: a case report.

Septal perforation is an anatomical defect of the nasal septum that leads to impaired nasal function, including obstruction and respiratory issues. In this study, a novel surgical approach was introduced to address septal perforations, focusing on the use of costal composite chondro-perichondrial grafts bilaterally in a symmetric manner. This composite graft, composed of costal cartilage and perichondrium, provides mechanical support, aids vascularization, and minimizes perichondrial shrinkage.

Neglected Superior Ophthalmic Vein Enlargement before Delayed Symptom of Carotid-Cavernous Fistula in a Blowout Fracture: A Case Report and Literature Review.

Carotid-cavernous fistula (CCF) is a rare condition. However, it should be suspected when there are traumatic facial fractures, because if not diagnosed, it can lead to permanent damage such as blindness. Traumatic CCF often presents delayed symptoms, and delayed diagnosis without prompt treatment can lead to permanent injuries in optic and cranial nerves III, IV, V, and VI as well as intracranial hemorrhage.

Nasal Osteotomies Revisited in Asians: Surface Aesthetics, Anatomical and Technical Considerations.

 Although osteotomy is commonly performed in rhinoplasty, it is difficult for less experienced surgeon to understand mechanism of the procedure. The primary goal of this study is to improve understanding of nasal osteotomy in Asians by considering the surface aesthetics and anatomy of the nose as well as their relationships with the surgical procedure.  Surface aesthetics, anatomic considerations, kinetics of medial and lateral osteotomy, fracture levels of osteotomy were discussed in detail by reviewing the previous publications and 18 years of our experience.

Means-tested COVID-19 stimulus payment and consumer spending: Evidence from card transaction data in South Korea.

This study examines the effect of a means-tested COVID-19 stimulus payment, which was provided by the Seoul Metropolitan Government in South Korea, on consumer spending. The Seoul government issued a one-off payment in the spring of 2020 for residents in the city living below the national median income. We use daily card transaction data aggregated by users' age, income and location of residence, and apply a difference-in-differences approach to assess the effect of the stimulus payment.

An Agonistic Monoclonal Antibody Targeting cMet Attenuates Inflammation and Up-Regulates Collagen Synthesis and Angiogenesis in Type 2 Diabetic Mice Wounds.

Background: Diabetic wounds account for 25 to 50 percent of total diabetic health care costs annually, and present overall healing rates of less than 50 percent. Because delayed diabetic wound healing is associated with impaired fibroblast function, the authors hypothesize that tyrosine kinase Met (cMet) agonistic monoclonal antibody will promote diabetic wound healing by means of stable activation of hepatocyte growth factor/cMet signaling.

Methods: Two 6-mm dorsal wounds were created in each mouse (6-week-old, male BKS.

Diagnosis and management of toxic shock syndrome after breast reconstructive procedures with silicone implants.

Breast implant insertion is one of the most commonly used methods for breast reconstruction after total mastectomy. However, infection is a common postoperative complication of implant insertion. In most cases, these infections can be managed with antibiotics and supportive therapy.

A dual padding method for ischial pressure sore reconstruction with an inferior gluteal artery perforator fasciocutaneous flap and a split inferior gluteus maximus muscle flap.

Background: Various surgical management methods have been proposed for ischial sore reconstruction, yet it has the highest recurrence rate of all pressure ulcer types. A novel approach combining the advantages of a perforator-based fasciocutaneous flap and a muscle flap is expected to resolve the disadvantages of previously introduced surgical methods.

Methods: Fifteen patients with ischial pressure ulcers with chronic osteomyelitis or bursitis, who underwent reconstructive procedures with an inferior gluteal artery perforator (IGAP) fasciocutaneous flap and a split inferior gluteus maximus muscle flap from January 2011 to June 2016, were analyzed retrospectively.

Clinical outcomes of a low-cost single-channel myoelectric-interface three-dimensional hand prosthesis.

Background: Prosthetic hands with a myoelectric interface have recently received interest within the broader category of hand prostheses, but their high cost is a major barrier to use. Modern three-dimensional (3D) printing technology has enabled more widespread development and cost-effectiveness in the field of prostheses. The objective of the present study was to evaluate the clinical impact of a low-cost 3D-printed myoelectric-interface prosthetic hand on patients' daily life.

A Large Scalp Defect Coverage With Pedicled Free Flap Using the Wrist as a Free Flap Carrier.

The absence of an adequate recipient vessel for free flap pedicle anastomosis near local defect sites discourages surgeons from performing free flap transfers over the scalp because of the challenging neck dissection and the thrombogenic potential of vein grafts for pedicle elongation. We present a case in which a large scalp defect was successfully reconstructed using the wrist as a "free flap carrier," which is an alternative method. A 78-year-old patient with a totally occluded common carotid artery presented to our clinic with a large scalp defect.

The Role of Family Behaviors in Determining Income Distribution: The Case of South Korea.

In this article, we examined what has contributed to the worsening income inequality and poverty between 1996 and 2011 in South Korea. We used a rank-preserving exchange method and a conditional reweighting method to assess the roles of family behaviors-including female labor force participation and family structure-characteristics of household heads, and men's earnings. The results showed that the change in men's earnings was a dominant factor in accounting for the increasing income inequality and poverty.

Decomposition Analyses of the Trend in Poverty Among Older Adults: The Case of South Korea.

Objectives: We examine the sharp increase in poverty among older adults since the mid-1990s in South Korea.

Method: We apply decomposition analyses to quantify the contributions of demographic and household characteristics, as well as income sources, to the rise in poverty among older adults.

Results: A rapid increase in the number of older adults living independently, combined with an increase in the number of old older adults, largely explains the rising poverty rate among Korean older adults.

The Effects of Old-Age Public Transfer on the Well-Being of Older Adults: The Case of Social Pension in South Korea.

Objectives: This study examines the effects of the social pension reform on the well-being of older adults in Korea. Our study provides an estimate of the impacts of social pension in an industrialized and urbanized context.

Methods: We use monthly panel data from the Household Income and Expenditure Survey of the Korea Statistical Office.

Do children from welfare families obtain less education?

In this study, we analyzed whether parents' receipt of welfare affects children's educational attainment in early adulthood, independent of its effect through changing family income. We used data from the Panel Study of Income Dynamics with information on parents' welfare receipt over the first 15 years of childhood. Cross-sectional results show that greater exposure to welfare is significantly associated with children's poorer educational attainment.
