To improve the oral health status of Korean people, it is necessary to encourage proper oral hygiene management habits, such as toothbrushing, through appropriate health promotion techniques. Therefore, the purpose of this study was to evaluate the removal of plaque and tooth abrasion using ultra-soft (filament 0.11~0.12 mm) and soft toothbrushes for toothbrushing. The plaque removal was performed using a dentiform and Arti-spray, and the Patient Hygiene Performance (PHP) index was calculated as the sum total score divided by the total number of surfaces. In the abrasivity experiment, according to the number of brushings, a micro Vickers hardness tester was used, and a sample in the range of 280~380 Vickers hardness number was selected. The number of toothbrushing stroke were 1,800 (2 months), 5,400 (6 months), 10,800 (12 months), and 21,600 (24 months). The tooth abrasion was measured using a scanning electron microscope. Statistical analysis was performed using IBM SPSS Statistics 22.0 and a p-value < 0.05 was considered significant. According to the results, there was no statistically significant difference in the degree of plaque removal between ultra-soft and soft toothbrushes. The difference in tooth abrasion between before and after toothbrushing was found to be greater with the soft toothbrushes than with the ultra-soft toothbrushes. Therefore, the ultra-soft toothbrush not only lowers tooth damage by reducing tooth abrasion, but also shows a similar ability to remove plaque as soft toothbrushes.

Human cytomegalovirus (HCMV) is a ubiquitous human pathogen and contains double stranded DNA genome with approximately 230 kbp. Molecular genomic studies of HCMV have been attempted in order to understand the pathogenesis and evolution of HCMV. However, studies on HCMV strains of Asian origin are limited. In this study, it was attempted to understand the genomics of HCMV isolated from Korea. Clinical strain LCW isolated from Korean patient was passaged in vitro cell culture, and subjected to next-generation sequencing. Complete genome sequence was obtained and compared with other HCMV strains. The LCW genome was found to contain 170 open reading frames (ORFs) and two ORF (RL5A and RL13) of the strain LCW were found to be truncated due to early stop codon. Phylogenetic analysis suggested that the strain LCW was closely related with Asian strains such as HCMV strains JHC and HAN. Common nucleotide sequences among the 3 Asian strains distinguishable from other strains were detected at 197 sites including 104 sites in ORFs.

Bupivacaine is frequently used for pain control and local anesthesia. However, it is associated with certain acute and fatal side effects, although rare, including cardiac and central nervous system toxicities. In particular, bupivacaine-induced cardiac toxicity may be fatal. This condition can be diagnosed as bupivacaine-induced cardiotoxicity by excluding other causes and determining a history of bupivacaine administration. However, in emergency situations, recognizing bupivacaine toxicity can be difficult due to the physician's lack of awareness regarding the condition or in the absence of clear communication regarding the patient's medical history. In the current case report, we describe our experience with strong suspected bupivacaine-induced cardiotoxicity in a patient who underwent cesarean section along with a review of the literature.

A Middle East respiratory syndrome (MERS) - coronavirus (CoV) cluster that attacked Korea in May 2015 revealed several weaknesses in Korea's health care system in the face of the crisis of an emerging infectious disease and its public health implications. This experience has shown that is necessary to prepare comprehensive countermeasures through the cooperation of civil and public agencies to prevent a second or even third MERS outbreak and to control future crises of infectious disease and public health. The MERS Policy Committee of the Korean Medical Association has thus proposed a master plan for reform of the national infectious disease prevention and management system to prepare a new framework for national infectious disease prevention and control. The specific targets of the master plan are improvement of the system of usage of medical services and of the medical culture among national health insurance subscribers, improvement of the emergency room management system to prevent the spread of infectious disease, the establishment of a support system to promote effective voluntary infectious disease prevention activities among medical institutions, the building of a public health crisis communication system in collaboration with medical organizations, the establishment of an independent Ministry of Health and capacity building of the Korea Centers for Disease Control (KCDC), the securing of an advanced research and development system in the field of prevention and control of infectious disease, and the capacity building of professional epidemiologists and personnel needed to prevent and control infectious disease. The five core strategies of the master plan have been planned by medical experts in this order of priority: the reform of the healthcare delivery system, the independence of the Ministry of Health and capacity building of the KCDC, fundraising for a public infection management fund, enforcement of medical organization infection control, and improvement of the emergency room management system.

BACKGROUND: In Korea, the prevalence, complications, and mortality rate of diabetes are rapidly increasing. However, investigations on the actual condition of diabetes management are very limited due to lack of nation-wide research or multicenter study. Hence, we have minutely inquired the current status of diabetes management and achievement of glucose target goal in general hospital offering education program. That way, we are able to furnish data for policy making of diabetes education and draw up guideline which may allow us to reduce the morbidity and mortality of diabetes. METHODS: The subjects consisted of 2,610 patients with type 2 diabetes who visited the 13 general hospital in Seoul or Gyeonggi region from March 19 to May 29, 2013. General characteristics, associated diseases, complications, and management status were investigated. RESULTS: The mean age was 61.0+/-11.6 years, body mass index was 25.0+/-3.3 kg/m2, and family history of diabetes was 50.5%. The mean duration of diabetes was 10.7+/-7.9 years and 53% received education about diabetes. The prevalence of hypertension and dyslipidemia were 59.2% and 65.5%, respectively, and 18.3% of the subjects were accompanied by liver disease. Diabetic retinopathy appeared in 31.6%, nephropathy in 28.1%, and neuropathy in 19.9% of the subjects. The mean glycosylated hemoglobin (HbA1c) level was 7.3%+/-1.3% and the achieving rate based on Korean Diabetes Association guideline (HbA1c <6.5%) was 24.8%, blood pressure (130/80 mm Hg or less) was 49.4%, and low density lipoprotein cholesterol (<100 mg/dL) was 63.6%. The reaching rate to the target level in four parameters (blood glucose, blood pressure, lipids, and body weight) was 7.8%. CONCLUSION: The blood glucose control rate was lower than other parameters, and the implementation rate of diabetes education was only 53%. Thus more appropriate glucose control and systematic diabetes education are imperative.

Endobronchial tuberculosis is defined as a tuberculous infection of the tracheobronchial tree and has a prevalence of up to 50% in active pulmonary tuberculosis cases. The most common complication of endobronchial tuberculosis is bronchial stenosis; benign fistula formation by endobronchial tuberculosis is rare, especially inter-bronchial fistula formation. We reported a rare case of a 73-year-old woman with a fistula between the right upper bronchus and bronchus intermedius. A diagnosis of inter-bronchial fistula caused by endobronchial tuberculosis was based on the results of chest computed tomography scans, bronchoscopy, and microbiological and pathological tests. The patient was treated with anti-tuberculous medication, and her symptoms gradually improved.

Central venous catheterization is a common diagnostic and therapeutic procedure in modern clinical practice. Pseudoaneurysms of the subclavian artery are rare and usually occur immediately after the causative event, whether the cause was trauma or a medical procedure. Here we report the rare case of a 71-year-old woman with delayed presentation of catheter-related subclavian pseudoaneurysm. The patient was treated for aspiration pneumonia with respiratory failure in another hospital. The patient's chest wall swelling began two weeks after the initial catheterization in the other hospital, probably because of slow leakage of blood from the injured subclavian artery caused by incomplete compression of the puncture site and uremic coagulopathy. She was successfully treated with ultrasound-guided thrombin and angiography-guided histoacryl injection without stent insertion or surgery. Her condition improved, and she was discharged to her home.

PURPOSE: To evaluate the use of scanning laser polarimetry (SLP, GDx VCC) to measure the retinal nerve fiber layer (RNFL) thickness in order to evaluate the progression of glaucoma. METHODS: Test-retest measurement variability was determined in 47 glaucomatous eyes. One eye each from 152 glaucomatous patients with at least 4 years of follow-up was enrolled. Visual field (VF) loss progression was determined by both event analysis (EA, Humphrey guided progression analysis) and trend analysis (TA, linear regression analysis of the visual field index). SLP progression was defined as a reduction of RNFL exceeding the predetermined repeatability coefficient in three consecutive exams, as compared to the baseline measure (EA). The slope of RNFL thickness change over time was determined by linear regression analysis (TA). RESULTS: Twenty-two eyes (14.5%) progressed according to the VF EA, 16 (10.5%) by VF TA, 37 (24.3%) by SLP EA and 19 (12.5%) by SLP TA. Agreement between VF and SLP progression was poor in both EA and TA (VF EA vs. SLP EA, k = 0.110; VF TA vs. SLP TA, k = 0.129). The mean (+/-standard deviation) progression rate of RNFL thickness as measured by SLP TA did not significantly differ between VF EA progressors and non-progressors (-0.224 +/- 0.148 microm/yr vs. -0.218 +/- 0.151 microm/yr, p = 0.874). SLP TA and EA showed similar levels of sensitivity when VF progression was considered as the reference standard. CONCLUSIONS: RNFL thickness as measurement by SLP was shown to be capable of detecting glaucoma progression. Both EA and TA of SLP showed poor agreement with VF outcomes in detecting glaucoma progression.

BACKGROUND: This study evaluates the effectiveness of immunochemotherapy and radiation therapy in the treatment of patients with primary bone lymphoma (PBL). METHODS: We retrospectively reviewed the medical records of 33 patients with PBL who were treated at 6 medical centers in Korea from 1992 to 2010. Clinicopathological features and treatment outcomes were analyzed. RESULTS: The median age of the patients participating in our study was 40 years. The most common sites of involvement were the pelvis (12.36%) and femur (11.33%). CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisolone) or CHOP-like regimens were administered to 20 patients (61%), and R-CHOP (rituximab plus CHOP) was administered to the remaining 13 patients (39%). The overall response rate was 89% (complete response, 76%; partial response, 12%). The overall survival (OS) of patients with solitary bone lesions was longer than that of patients with multiple bone lesions (median OS: not reached vs. 166 months, respectively; P=0.089). Addition of rituximab to CHOP did not significantly affect either OS or progression-free survival (P=0.53 and P=0.23, respectively). Combining radiation therapy with chemotherapy also did not improve the OS or progression-free survival of patients with solitary bone lesions. CONCLUSION: Conventional cytotoxic chemotherapy remains an effective treatment option for patients with PBL. Additional benefits of supplementing chemotherapy with either rituximab or radiation therapy were not observed in this study. Further investigation is needed to characterize the role of immunochemotherapy in treating patients with PBL.
