Purpose: Respiratory syncytial virus (RSV) is one of the most common causes of respiratory tract infections, especially in patients aged < 3 years. There are 2 antigenically different RSV subtypes, A and B. This study aimed to assess if the RSV subtype is independently associated with increased disease severity. Methods: We retrospectively collected data from the medical records of children hospitalized with RSV infection, aged < 3 years at Dong-A University Hospital between September, 2014 and December, 2018. Results: RSV A and RSV B infections were observed in 111 and 66 cases, respectively. Pneumonia was most commonly observed, followed by bronchiolitis in both subtypes. There were no significant differences between the groups regarding birth weight, gestational age, and incidence of having siblings. The duration of admission, duration of fever, and severity index were similar between the groups. The incidence of high fever (> 39°C) was slightly higher in the RSV B group (13.6%) than in the RSV A group (11.7%), although the difference was not statistically significant. Laboratory findings, including the neutrophil-lymphocyte ratio, were similar between the groups. The incidence of systemic steroid therapy was higher in the RSV A group (12.6%) than in the RSV B (3.0%) group (P= 0.03). Patients aged < 12 months, the incidences of oxygen therapy (P= 0.03) and systemic steroid therapy (P= 0.04) were higher in the RSV A group, suggesting that patients aged < 12 months with RSV A infection may have clinically more severe disease. Conclusion We recommend intensive monitoring if RSV A infection is detected in young children under 12 months.

PURPOSE: The aim of this study was to assess the degree of awareness and actual practice of dental practitioners regarding infection control during prosthodontic treatment. MATERIALS AND METHODS: Study participants were composed of dentists, dental hygienists, dental technicians working at dental university hospital, general hospital, dental hospital and dental clinics in Daejeon, Korea (n=126). The questionnaires included the data on general characteristics, education, awareness and practice of infection control procedures during prosthodontic treatment through personal self-administration survey. Awareness and practice were measured by Likert scale ranging from 1 to 5. Statistical analysis was done by one-way ANOVA. Influence of awareness on practice was estimated by regression analysis. RESULTS: 27.7% of the respondents answered that the infection control education regarding prosthodontic treatment is insufficient. The mean value of awareness and practice of infection control during the prosthodontic treatment were 2.72 +/- 0.80, 1.58 +/- 0.88, respectively. The mean value of practice who answered that had education curriculum at college was 1.62 +/- 0.9, and 1.31 +/- 0.49 who did not. The mean value of awareness who equipped guideline was 3.01 +/- 0.9, and 2.56 +/- 0.70 who did not. CONCLUSION: 1. The respondents who received the infection control education by college curriculum showed higher degree of practice than the respondents who did not. 2. The respondents who have appropriate infection control guidebook in their workplace showed higher degree of awareness than the respondents who did not. 3. There was a correlation between the awareness and practice of infection control during prosthodontic treatment; the degree of awareness becomes higher, so does the degree of practice. 4. During the prosthodontic treatment, the degree of practice was lower than the degree of awareness on infection control.

The average life expectancy has been increased, so the proportion of elderly patients that visit to the dental clinic for prosthetic restoration has increased. Elderly patients have various chronic diseases. Recent trends show an increase of osteoporosis in elderly patients, and thus, the number of osteoporosis patients is expected to escalate. Currently, the most widely used drug for osteoporosis is bisphosphonate. However, osteonecrosis of the jaw has been reported as a side effect derived from long-term oral administration or injection treatment of the drug. Surgical dental treatment was the main cause of medication related osteonecrosis of the jaw (MRONJ). As MRONJ is very difficult to cure, it is important to take preventive measures. Surgical operation may be needed for the mouth preparation before prosthetic restoration. For successful treatment, the dentist should have a full understanding of osteoporosis and show a continued interest toward this disease for careful management.

One of the techniques for improvement of the nasolabial fold is the insertion of a fat or dermis fat graft. Guyuron introduced the dermis fat graft from the suprapubic area or the groin region. We innovated a procedure of rhytidectomy and dermis fat graft from rhytidectomy skin to the nasolabial fold area. In casse of a 48-year-old man a conventional cervicofacial flap was elevated from the preauricular and cervico-postauricular regeon to the nasolabial fold. The excess excised skin from the preauricular area was deepithehialized, contoured, and grafted to the nasolabial fold. Three pull-out suture were placed at the medial margin of the dermis fat graft to secure its position. This procedure have several advantages. First, a dermis fat graft under the nasolabial crease not only thickens the soft tissue but also provides a shield to prevent reattachment of the fibrous band to the dermis, which are causative of a recurrent crease. Second, it has no donor site morbidity. Third, the subcutaneous tissue of the preauricular area has much fascial component which survives better than fat injection of strip fat graft. Last, under the direct vision surgeon could place the graft in position he wants. This technique could be used in Asian whose skin is thick and whose maxilla is protruded.

Prosthetic restorations through implants were popularized, and they became routine treatments. Small accessories used in the implant prosthodontic procedure are more likely to slip or fall off the dentist's hands. If the dental appliance or material passes into the upper gastrointestinal tract, there is a high possibility of excretion to the outside of the body without complications, but serious complications may occur depending on the type of foreign body. If the foreign body is passed to the airway, it is an emergency situation, and if it is not done properly, it can be fatal. The purpose of this review report is to investigate the process of foreign body ingestion or aspiration during dental treatment, and the method of prevention and treatment.

Objectives: This study aims to suggest ways to improve the oral care competencies of caregivers by strengthening oral care services for the elderly with mobility difficulties in long-term care facilities. Methods: Through a web survey, 215 caregivers were invited, their actual situation was identified, and necessary educational tasks were listed. We developed 16 types of card news, two types of songs, and four types of video clips that can be used in the field for the listed educational topics. Several meetings with expert developers resulted in developing the components and design of an oral health management platform for caregivers in long-term care facilities. Results: As a result of the web survey, many caregivers in long-term care facilities needed education or information on oral care methods, and many people felt difficulties in oral care for the elderly. About 40% of the caregivers had no experience in oral health education, and many learned how to care through unsystematic apprenticeships. Most of the education content that caregivers prioritized were brushing teeth and denture management, but there were also needs such as management of dementia and bedridden patients, non-cooperative oral care, nutrition management, and oral auxiliary products use. Conclusions In conclusion, this study reviewed and suggested digital platforms such as strengthening caregivers’ competency in long-term care facilities, providing customized educational information, discovering oral problems of the elderly, and reporting oral difficulties to experts.

Objectives: This study aims to explore the experience of caregivers in oral health care of the elderly in long-term care facilities, identify the problems, and collect opinions, and to seek improvement directions for strengthening competency and improving services of oral health care for the elderly. Methods: Data on the experience in oral health care of the elderly were collected through focus group interviews (FGI) targeting caregivers in long-term care facilities. The grounded theory method was used. The interview content was categorized by open coding, and a paradigm model was presented by identifying the relationship between the categories through axial coding. Selective coding found core categories. Results: As a result of categorizing the caregivers’ oral care experience of the elderly, 15 categories, 40 sub-categories, and 125 concept/phenomena codes were derived. The central phenomenon was the difficulty of implementing sustainable oral health care. The deterioration of the mental and physical functions of the elderly, the work characteristics of caregivers, and the lack of linkage with internal and external resources of the facility acted as causal conditions for the central phenomenon. The caregiver’s oral health education experience acted as an intervening condition. In an effort to improve the problem, an interaction strategy was derived. Conclusions It is possible to seek delivery of sustainable oral health care services by caregivers by improving the quality of oral health education and establishing an oral health care service system for the elderly.

Purpose: This study was to investigate the dentists’ experience and awareness of foreign body ingestion and aspiration during dental prosthetic treatment. Materials and Methods: A survey of 157 dentists working at 108 dental institutions in Daejeon and Chungcheong provinces was carried out and frequency analysis was conducted. Chi-square test was conducted to find out the difference between the sociodemographic data and experience of foreign body ingestion and aspiration of patients and independent sample t-test was conducted to find out the difference in awareness depending on whether receiving related education. Results: The percentage of dentists experiencing dropping foreign body into patients’ oral cavity was 99.4% and the percentage of dentists experiencing foreign body ingestion and aspiration of patients was 53.5%. There were more dentists who experienced foreign body ingestion and aspiration of patients in male than female, longer working career, and general practitioners than specialists (P < .05). 50.3% of the respondents received related education. When they receive related education, they had low degree of concern, high confidence in coping with situations, and low willingness to receive education in the future (P < .05). Conclusion The percentage of foreign body dropping was 16% higher in prosthetic treatment than general treatment. The percentage of dentists with experience of foreign body ingestion and aspiration of patients was 53.5%. Among them, 92.9% experienced foreign body ingestion of patients and 7.1% of them experienced foreign body aspiration of patients.

Pulmonary aspiration of gastric contents is a very rare but one of the most feared complications of anesthesia. The risk factors are gastroesophageal reflux, previous aspiration, renal failure, difficult intubation and trauma. The incidence of aspiration during anesthesia of children has been reported to be more common than adults. This report describes the case of a 7-year-old female patient who had experienced pulmonary aspiration during induction of anesthesia. With fiberoptic brochoscopy, the aspirates in both bronchi were carefully suctioned, and the following chest X-ray and blood gas findings improved. She was transferred to the intensive care unit for respiratory support and showed no further problems.
