BACKGROUND: This study aimed at assessing the knowledge of the general public about novel influenza and the extent of preventive measures undertaken when information on novel influenza and its preventive measures was extensively broadcasted during the novel influenza outbreak. METHODS: Between September 21 and October 31, self-report questionnaires were distributed to 1,200 persons. The completed questionnaires were collected from 1,025 persons. The collected data was used to determine the frequency and percentage as well as to conduct analyses such as t-test, ANOVA, and logistic regression by using SPSS WIN 12.0. RESULTS: The knowledge on novel influenza and the performance of preventive measures were scored at 6.58 and 5.10, respectively, on a scale of 12. This finding suggested that the knowledge on novel influenza and the performance of preventive measures were low. The significant factors influencing the participants' knowledge on novel influenza were age and the experience of watching relevant educational programs on television, whereas the factors influencing the performance of preventive measures were academic career, working status, and the experience of watching relevant educational programs on television. Between knowledge and implementation of preventive measures, there was positive correlation at low level (r=0.112, P<0.001). CONCLUSION: In conclusion, this study demonstrated that factors influencing the knowledge on and the performance of preventive measures against a disease should be considered when developing prevention strategies, such as broadcast of educational programs on television, against influenza or similar infectious diseases during an outbreak.

Purpose: The purpose of this study is to investigate the stress response and sleep state of the new patients who visit the hospital for prosthodontic treatment due to tooth loss to make reference to further treatment direction. Materials and methods: Examinations, consultations, and surveys were conducted on 236 patients (94 males, 142 females, and 24-86 years old), who newly registered at the department of prosthodontics at Pusan national university hospital, for 2 years from 2018. The number of remaining teeth, edentulous arch, possibility of mastication, and future prosthetic treatment directions were recorded. The visual analogue scale (VAS), stress response inventory (SRI) and Insomnia severity index (ISI) were used as tools to measure patient’s subjective discomfort, stress response, and sleep status. Results: Among the entire prosthodontic patient group, the average value of ‘fatigue’ was significantly higher among the 7 items of SRI, and the value of ‘aggression’ was significantly lower (P<.001). There are a significant difference between the edentulous and full dentition in the oral discomfort value measured by VAS (P=.004). In cases where less than 20 teeth remain, mastication is impossible, and patients who are planning treatment with removable prostheses, VAS value and ‘depression’ and ‘fatigue’ values in SRI were higher than those in the reverse case (P<.05).The patients showed severe level in VAS value have high value of ‘tension’, ‘somatization’, ‘depression’, ‘fatigue’and ‘frustration’in SRI than non-serious patients (P<.05). Clinical insomnia occurred in 11.4% of all patients, and women had significantly lower sleep quality than men (P=.044). Patients with insomnia showed significantly higher scores on the VAS value and all 7 SRI items than those of normal sleepers (P<.05). Conclusion The new prosthetics had high ‘fatigue’ value among the 7 items of SRI. The oral condition, number of residual teeth and mastication function and clinical insomnia affected oral discomfort and the stress response.

Merkel cell carcinoma (MCC) is an aggressive neuroendocrine carcinoma with a high rate of metastasis. MCC is rarely suspected during clinical examination, thus requiring biopsy to establish a pathologic diagnosis. In addition, MCC sometimes occurs in double primary cancers. Although there have been reviews on double primary cancers, only a few cases involving MCC have been described. Herein, we report a case of a 54-year-old female patient who presented to our clinic with a diagnosis of earlobe MCC following an excisional biopsy performed by another clinic. Further evaluation, including chest imaging, revealed a mass in the lung. The patient underwent a wide excision of the right earlobe, and video-assisted thoracic surgery on the lung. Pathology confirmed MCC in the right earlobe and adenocarcinoma in the lung. The patient underwent postoperative adjuvant chemotherapy followed by radiotherapy. Up to this point, 3 years after the surgery, there has been no evidence of recurrence.

Closed mouth impression technique by using bite tray is preferred for single tooth impression taking. However, for implant impression taking, open mouth impression technique by using single arch tray is generally used whether it is for single implant or multiple implant. Closed mouth impression technique by using bite tray can save time and materials. It also decreases the chance of error occurrence when a model is mounted on an articulator. In this case report, we tried to show a satisfying result of fabricating single implant fixed prosthodontics after bite tray impression taking by using two different copings for closed mouth impression.

In the case of edentulous patients, the total amount of occlusal force is dispersed by the keratinized gingiva during mastication, in result, causing lower masticatory and chewing efficiency. In particular, the mandibular area has more side effects such as pain than the maxilla has. It gets worse when the patient has more absorption of alveolar bone, but the implant treatment is often interrupted due to the existence of the inferior alveolar nerve. In this case, a patient treated with the all-on-4 method by placing the implant in the anterior part of mandible and with the conventional complete denture for the maxilla has maintained without complications and was satisfied with the restoration both functionally and esthetically.

OBJECTIVE: To evaluate the incidence, the time of detection, classification, and risk factors of thyroid dysfunction in very low birth weight (VLBW) and sick infants in order to help with the diagnosis and treatment of thyroid dysfunction in the neonatal intensive care unit (NICU). METHODS: We reviewed the medical records of 78 infants, who were admitted for more than 1 month in the NICU at Chungbuk National University Hospital from July 2004 through June 2006. In these infants, at least to 2 thyroid function tests were performed, a initial screening whthin 2 weeks of age and a repeated thyroid function test after 2 weeks of age. RESULTS: 1) The study infants were divided into 2 groups, VLBW (birth weight < 1,500 g) and NVLBW (birth weight > or =1,500 g). 2) In the VLBW groups (n=48), 24 infants (50%) showed thyroid dysfunction. Six infants (12.5%) were detected at initial screening test and all had transient hypothyroxinemia. The remaining 18 infants (37.5%) were detected at repeated tests, most commonly detected at 4~8 weeks of age (n=8). Their types of thyroid dysfunction were primary hypothyroidism (PH) with a delayed marked TSH rise (n=3), PH with a delayed mild TSH rise (n= 7), euthyroid sick syndrome (ESS, n=8), and central hypopituitary hypothyroidism (HH, n=1). 3) In the NVLBW groups (n=30), 11 infants (36.7%) showed thyroid dysfunction. Three infants (10%) were detected at initial screening test, while 8 (26.7%) were detected at repeated tests. Their types of thyroid dysfunction were PH (n=5), ESS (n=3), transient hyperthyrotropinemia (n=2), and HH (n=1). 4) Among 35 infants with thyroid dysfunction, 20 infants (57.1%) were treated with thyroxine. CONCLUSION: Thyroid dysfunction was very common in sick infants in the neonatal intensive care unit, especially in the very low birth weight infants. Often, they were not detected at the initial screening test, but detected at later repeated tests. The repeated thyroid function test need to be performed in infants at risk for late detection of thyroid dysfunction after 2~4 weeks of age.

PURPOSE: The purpose of this study was to assess the difference in efficacy between calcium metaphosphate (CMP)-coated implant fixtures and conventional resorbable blasted media (RBM) processed implant fixtures. MATERIALS AND METHODS: This study targeted 50 implants from 44 patients who visited Dankook University Dental Hospital. Implantations were done separately for RBM treated and CMP-coated implants, although their design was the same. Calcium metaphosphate has a quicker biodegradation process through hydrolysis compared to other phosphate calcium groups. For the first year of the implantation, the resorption volume of marginal bone analyzed via radiography and perio-test value were measured, under the check plan. Their analyses were composed of a non-inferiority trials test. A 95% level of reliability was used. RESULTS: In the comparative analysis of the resorption volume of marginal bone and the perio-test value, no statistically significant difference was found between the CMP-coated implants and RBM implants. CONCLUSION: One year after the implant placement, CMP-coated implants were found not to be inferior to the conventional RBM implants.

BACKGROUND: Several publications have reported the successful, safe use of Laryngeal Mask Airway (LMA)-Classic devices in patients undergoing laparoscopic surgery. However, there have been no studies that have examined the application of volume-controlled ventilation (VCV) or pressure-controlled ventilation (PCV) using a LMA during gynecological laparoscopy. The aim of this study is to compare how the VCV and PCV modes and using a LMA affect the pulmonary mechanics, the gas exchange and the cardiovascular responses in patients who are undergoing gynecological laparoscopy. METHODS: Sixty female patients were randomly allocated to one of two groups, (the VCV or PCV groups). In the VCV group, baseline ventilation of the lung was performed with volume-controlled ventilation and a tidal volume of 10 ml/kg ideal body weight (IBW). In the PCV group, baseline ventilation of the lung using pressure-controlled ventilation was initiated with a peak airway pressure that provided a tidal volume of 10 ml/kg IBW and an upper limit of 35 cmH2O. The end-tidal CO2, the peak airway pressures (Ppeak), the compliance, the airway resistance and the arterial oxygen saturation were recorded at T1: 5 minutes after insertion of the laryngeal airway, and at T2 and T3: 5 and 15 minutes, respectively, after CO2 insufflation. RESULTS: The Ppeak at 5 minutes and 15 minutes after CO2 insufflation were significantly increased compared to the baseline values in both groups. Also, at 5 minutes and 15 minutes after CO2 insufflation, there were significant differences of the Ppeak between the two groups. The compliance decreased in both groups after creating the pneumopertoneim (P < 0.05). CONCLUSIONS: Our results demonstrate that PCV may be an effective method of ventilation during gynecological laparoscopy, and it ensures oxygenation while minimizing the increases of the peak airway pressure after CO2 insufflation.
