Emotional Distress of the COVID-19 Cluster Infection on Health Care Workers Working at a National Hospital in Korea.

Background: Frontline healthcare workers responding to coronavirus disease 2019 (COVID-19) inevitably face tremendous psychological burden. Thus, the present study aimed to identify the psychological impact and the factors contributing to the likely increase in emotional distress of healthcare workers.

Methods: The participants include a total of 99 healthcare workers at Bugok National Hospital.

Hypochlorous Acid Versus Saline Nasal Irrigation in Allergic Rhinitis: A Multicenter, Randomized, Double-Blind, Placebo-controlled Study.

Background: Low concentrations of hypochlorous acid (HOCl) have proven antipruritic, anti-inflammatory, and antimicrobial effects without toxicity, although the mechanism has not been fully elucidated.

Objective: The aim of this study was to evaluate the effectiveness of HOCl nasal irrigation to reduce allergic rhinitis (AR) symptoms compared with saline nasal irrigation.

Methods: This was multicenter, randomized, double-blind, placebo-controlled study.

Short-term treatment outcomes and safety of two representative brands of the fifth-generation silicone gel-filled breast implants in Korea.

It is allegedly reported that the BellaGel SmoothFine (HansBiomed Co. Ltd., Seoul, Korea) and Motiva Ergonomix (Establishment Labs Holdings Inc.

Factors Influencing Readiness to Change Among Hazardous Drinkers in South Korea.

the precontemplation group (those who had never considered that they had a problem) and the more than contemplation group (those who were at least open to the idea they might have a problem). Measured variables were personal characteristics, lifetime alcohol use history, and responses to the Drinker Inventory of Consequences, Alcohol Use Disorder Identification Test, Alcohol Dependence Scale, Motivational Structure Questionnaire for Alcoholics, and the Alcohol Outcome Expectancies Scale. Behavioral, psychiatric, and psychological factors were evaluated according to the responses to the Rosenberg Self-Esteem Scale, Zung Self-Rating Depression Scale, Barratt Impulsiveness Scale, State-Trait Anxiety Inventory, and State-Trait Anger Expression Inventory.

3D-Printable Carbon Nanotubes-Based Composite for Flexible Piezoresistive Sensors.

The intersection between nanoscience and additive manufacturing technology has resulted in a new field of printable and flexible electronics. This interesting area of research tackles the challenges in the development of novel materials and fabrication techniques towards a wider range and improved design of flexible electronic devices. This work presents the fabrication of a cost-effective and facile flexible piezoresistive pressure sensor using a 3D-printable carbon nanotube-based nanocomposite.

Short-term Safety of Augmentation Mammaplasty Using the BellaGel Implants in Korean Women.

Unlabelled: Asian women are stereotypically characterized by a slim body, smaller breasts and areolae, and larger nipples when compared with White women. They would therefore be vulnerable to displacement of a breast implant if they receive larger implants. They are also prone to hypertrophic and prolonged hyperemic scars.

A Prospective Randomized Clinical Trial of Combination Therapy with Proton Pump Inhibitors and Mucolytics in Patients with Laryngopharyngeal Reflux.

Objectives: To identify whether combination therapy with mucolytics and proton pump inhibitors (PPIs) leads to faster and more effective symptomatic relief in patients with laryngopharyngeal reflux (LPR).

Methods: Patients diagnosed as LPR with a reflux symptom index (RSI) ≥ 13 and a reflux finding score (RFS) ≥ 7 were enrolled in this prospective study. Patients were randomly allocated to control (PPI only) or experimental (PPI + mucolytics) groups and changes in RSI and RFS values were assessed at 1- and 3-month follow-up.

Development of a mouse model of eosinophilic chronic rhinosinusitis with nasal polyp by nasal instillation of an Aspergillus protease and ovalbumin.

One subtype of chronic rhinosinusitis with nasal polyps (CRSwNP) is characterized by the development of a T-helper type 2 (Th2) response and eosinophilic infiltration. Here, we aimed to establish an eosinophilic CRSwNP murine model, which would be essential to understand the underlying pathogenesis and establish a treatment strategy. C57BL/6 mice were challenged intranasally with a mixture of an Aspergillus oryzae-derived protease (AP) and ovalbumin (OVA) for 6, 8, or 12 consecutive weeks (12 mice/group); control mice received the same volume of phosphate-buffered saline for 12 weeks (n = 12).

Times to Discontinue Antidepressants Over 6 Months in Patients with Major Depressive Disorder.

Objective: The aim of the present study was to investigate differences in discontinuation time among antidepressants and total antidepressant discontinuation rate of patients with depression over a 6 month period in a naturalistic treatment setting.

Methods: We reviewed the medical records of 900 patients with major depressive disorder who were initially prescribed only one kind of antidepressant. The prescribed antidepressants and the reasons for discontinuation were surveyed at baseline and every 4 weeks during the 24 week study.

Columellar Incision Scars in Asian Patients Undergoing Open Rhinoplasty.

Importance: An open approach has been adopted for rhinoplasty because of its wide and undistorted exposure. The formation of a columellar incision scar is the main drawback of this approach.

Objective: To evaluate the incidence and evolution of and risk factors for columellar incision scars in an Asian population.

Management and outcomes of chronic otitis media in patients who received solid organ transplantation.

Objectives: Control of perioperative infection can increase the success rate of organ transplant. The incidence, clinical features, and optimal management of chronic otitis media (COM) in solid organ transplant recipients have not been adequately evaluated. We therefore assessed the incidence and clinical course of COM in solid-organ transplant recipients.

Maxillary sinus hypoplasia with a patent ostiomeatal complex: A therapeutic dilemma.

Objective: Maxillary sinus hypoplasia (MSH) is a radiologically detectable abnormality of the maxillary sinus that can be associated with sinusitis. Symptomatic MSH patients with a patent ostiomeatal complex (MSHPO) constitute a particular therapeutic challenge.

Methods: Ostiomeatal unit CT scans of 1293 patients with various sinonasal symptoms such as purulent discharge, postnasal drip, facial pain or headache were reviewed to determine the incidence, clinical symptoms and outcomes of MSHPO following medical treatment.

Petrous apex cholesterol granuloma presenting as endolymphatic hydrops: a case report.

A petrous apex cholesterol granuloma (PACG) is the most common lesion of the petrous apex mass. Affected patients present with various symptoms such as hearing loss, vertigo, headache, tinnitus, facial spasms, and diplopia. We report the case of a 32-yr-old man with a PACG, who was first misdiagnosed with Ménière's disease.

Power quality control of an autonomous wind-diesel power system based on hybrid intelligent controller.

Wind power generation is gaining popularity as the power industry in the world is moving toward more liberalized trade of energy along with public concerns of more environmentally friendly mode of electricity generation. The weakness of wind power generation is its dependence on nature-the power output varies in quite a wide range due to the change of wind speed, which is difficult to model and predict. The excess fluctuation of power output and voltages can influence negatively the quality of electricity in the distribution system connected to the wind power generation plant.

A study of the reliability and validity of the korean version of the penn alcohol craving scale for alcohol-dependent patients.

Objective: The Penn Alcohol Craving Scale (PACS) is a stronger predictor of subsequent drinking and relapse of alcohol dependence that can be administered more quickly and easily than other craving scales. The goal of this study was to develop the Korean version of the Penn Alcohol Craving Scale (PACS-K).

Methods: To examine the psychometric properties of the PACS-K, responses were chosen from 80 patients admitted to a treatment facility for alcohol dependence.
