Objectives: This study aims to assess dental hygienists’ level of digital literacy and its effect on occupational self-efficacy and organizational commitment. Methods: The online survey results, obtained from 307 respondents, were statistically analyzed using frequency analysis, t-test, one-way ANOVA, and multiple regression analysis with the IBM SPSS 20.0 software. Results: The factors affecting the technology portion of digital literacy included age (P＜0.001), years in career (P＜0.001), number of personnel in workplace (P=0.009), level of education (P=0.001), region of workplace (P=0.002), and form of workplace (P=0.021). The factors affecting the application portion of digital literacy included age (P＜0.001), years in career (P=0.009), and number of personnel in the workplace (P=0.008). The level of occupational self-efficacy positively affected the technology portion of digital literacy, while organizational commitment positively affected the technology portion and negatively affected the application portion of digital literacy. Conclusions Although this study has limitations, it carries significance as a survey of dental hygienists’ digital literacy standing. To adapt to and function in the current society of digital informatics, ongoing education and research on digital literacy are warranted.

PURPOSE: We present a case of orbital abscess following porous orbital implant infection in a 73-year-old woman with rheumatoid arthritis. METHODS: Just one month after a seemingly uncomplicated enucleation and porous polyethylene (Medpor(R)) orbital implant surgery, implant exposure developed with profuse pus discharge. The patient was unresponsive to implant removal and MRI confirmed the presence of an orbital pus pocket. Despite extirpation of the four rectus muscles, inflammatory granulation debridement and abscess drainage, another new pus pocket developed. RESULTS: After partial orbital exenteration, the wound finally healed well without any additional abscess formation. CONCLUSIONS: A patient who has risk factors for delayed wound healing must be examined thoroughly and extreme care such as exenteration must be taken if there is persistent infection.

BACKGROUND: Implant malposition can produce unsatisfactory aesthetic results after breast augmentation. The goal of this article is to identify aspects of the preoperative surgical planning and intraoperative flap fixation that can prevent implant malposition. METHODS: This study examined 36 patients who underwent primary dual plane breast augmentation through an inframammary incision between September 1, 2012 and January 31, 2013. Before the surgery, preoperative evaluation and design using the Randquist formula were performed. Each patient was evaluated retrospectively for nipple position relative to the breast implant and breast contour, using standardized preoperative and postoperative photographs. The average follow-up period was 10 months. RESULTS: Seven of 72 breasts were identified as having implant malposition. These malpositions were divided into two groups. In relation to the new breast mound, six breasts had an inferiorly positioned and one breast had a superiorly positioned nipple-areolar complex. Two of these seven breasts were accompanied with an unsatisfactory breast contour. CONCLUSIONS: We identified two main causes of implant malposition after inframammary augmentation mammaplasty. One cause was an incorrect preoperatively designed nipple to inframammary fold (N-IMF) distance. The breast skin and parenchyma quality, such as an extremely tight envelope, should be considered. If an extremely tight envelope is found, the preoperatively designed new N-IMF distance should be increased. The other main cause of malposition is failure of the fascial suture from Scarpa's fascia to the perichondrium through an inframammary incision. As well, when this fixation is performed, it should be performed directly downward to the perichondrium, rather than slanted in a cranial or caudal direction.

Two patients, bulging fetal membrane accompanied with cervical dilatation & effacement in the late second-trimester, were treated by modified Shirodkar method. Pregnancies were prolonged effectively and viable fetuses were delivered in both cases. Our cases may help make objective decision prior to attempting cerclage placement when cervix is markedly dilated and something should be done to save pregnancy.

BACKGROUND: Phantom limb sensation is an unusual position sense of the extremity during nerve block that the position of extremity is misinterpreted as being flexed, or elevated, when actually they are in neutral position. Whether it is from the fixation of proprioceptive input at the time of motor blockade or from unmasking of the pattern which has been already present in the CNS is still controversial. We perfomed this study under the assumption that phantom limb sensation can still be reproduced without the influence of position at the time of nerve blockade. METHODS: Thirty-six patients scheduled for elective orthopedic surgery were randomly assigned. For 26 patients, spinal anesthesia was performed with hyperbaric 0.5% tetracaine or bupivacaine at lateral decubitus position and the position was changed to supine immediately. Existence of phantom limb sensation and the level of anesthesia was recorded at 10 and 20 minutes after injection of local anesthetics. For 10 patients, same local anesthetics were injected after patient's legs were straightened in lateral decubitus position. RESULTS: Forteen out of 26 patients whose position were changed to supine immediately after the injection of local anesthetics experienced phantom limb sensations. Five out of 10 patients whose legs were kept straight before the injection of local anesthetics experienced phantom limb sensations. Previous history of trauma was positively related to the expression of phantom limb sensation. CONCLUSION: Our data showed that the expression of phantom limb sensation is reproducible. And this was not related to the position at the time of spinal anesthesia. Trauma seems to be an important factor related to the expression of phantom limb sensation.

PURPOSE: To evaluate the effectiveness and complications of temporary inferior vena cava filters in deep vein thrombosis. METHOD: We retrospectively evaluated the clinical data of 35 patients who underwent percutaneous insertion of a temporary, retrievable IVC filter during treatment of deep vein thrombosis between 2003 and 2006. A Tulip(R) was used in 25 patients, and an OptEase(R) was used in 10 patients. Indications for filter insertion included thrombolytic therapy (n=29), long floating IVC thrombosis (n=4), and pulmonary thromboembolism history with recurrent venous-thromboembolism (n=2). Deep vein thrombosis was treated with an endovascular procedure in 33 patients and anticoagulation therapy in 2 patients. RESULT: Complete symptom resolution was achieved in all patients. The temporary IVC filters were successfully retrieved in 28 of 35 patients (mean duration of filter placement: 9.57 days), but retrieval failed in 7 patients (thrombus in filter, 3 cases; remnant IVC thrombosis, 1 case; remnant iliac vein thrombosis/venous stenosis in high risk patient, 2 cases; in-hospital mortality due to underlying heart disease, 1 case). There were no cases of pulmonary embolism and no serious IVC filter-related complications during insertion, retraction, or remnant IVC filter follow-up. CONCLUSION: Temporary, retrievable IVC filters were effective in the prevention of pulmonary embolism. Further investigations are necessary to determine long-term outcome data for filters left in place.

PURPOSE: The present study assessed the diagnostic significance of digital infrared thermal imaging (DITI) in determining the inflammatory state of patients with nonspecific orbital inflammation. METHODS: The present study included 11 patients diagnosed with nonspecific orbital inflammation between December 2009 and March 2011 and who were followed-up for more than 6 months. All patients were all diagnosed based on computed tomography (CT), magnetic resonance image (MRI) and tissue biopsy. The grade of eyelid swelling was classified as 5 and severe compared with the temperature of location. The temperature of the upper eyelid, caruncle, medial conjunctiva, lateral conjunctiva, lower eyelid, cornea and lateral orbit were measured with DITI. RESULTS: When comparing the normal eye with the diseased eye in patients with nonspecific orbital inflammation, the temperature of the upper eyelid and cornea were statistically significant (p = 0.003, p = 0.038, respectively, Mann-Whitney test). The correlation between the grade of eyelid swelling and the temperature of location was most highly related in the temperature of the upper eyelid (Spearman's correlation coefficient, r = 0.55, p = 0.008) and cornea (Spearman's correlation coefficient, r = 0.45, p = 0.037). CONCLUSIONS: DITI may aid in evaluating the inflammatory state of nonspecific orbital inflammation. In particular, the temperature of the upper eyelid and cornea can be very useful indicator. Future studies, including larger study population are necessary in order to confirm DITI as a diagnostic tool which can assess the results of medical treatment by comparing temperature before and after treatment.

OBJECTIVES: A healthcare decision-making support model and rule management system is proposed based on a personalized rule-based intelligent concept, to effectively manage chronic diseases. METHODS: A Web service was built using a standard message transfer protocol for interoperability of personal health records among healthcare institutions. An intelligent decision service is provided that analyzes data using a service-oriented healthcare rule inference function and machine-learning platform; the rules are extensively compiled by physicians through a developmental user interface that enables knowledge base construction, modification, and integration. Further, screening results are visualized for the self-intuitive understanding of personal health status by patients. RESULTS: A recommendation message is output through the Web service by receiving patient information from the hospital information recording system and object attribute values as input factors. The proposed system can verify patient behavior by acting as an intellectualized backbone of chronic diseases management; further, it supports self-management and scheduling of screening. CONCLUSIONS: Chronic patients can continuously receive active recommendations related to their healthcare through the rule management system, and they can model the system by acting as decision makers in diseases management; secondary diseases can be prevented and health management can be performed by reference to patient-specific lifestyle guidelines.

PURPOSE: to measure mood disturbance of Korean patients with dysthyroid ophthalmopathy according to the severity of ophthalmopathy. METHODS: Fifty patients with dysthyroid ophthalmopathy (mean age: 46.6+/-12.1 years; 32 female patients and 18 male patients) were included, and classified into 2 groups according to the disease severity. Twenty-five patients were classified with moderate/severe diseases (study group) and 25 patients classified with negligible/mild disease (control group). All patients completed a mood survey of 65 questions to assess differences in the degree of emotional distress. RESULTS: Analysis of each group showed that patients with moderate/severe ophthalmopathy had significantly greater emotional distress than patients with negligible/mild ophthalmopathy according to the Korean Profile of Mood States mean total score (p=0.03). In particular, patients with disfigurement (proptosis predominant group) had significantly worsen emotional distress compared with the control group (p=0.007), whereas patients with diplopia (diplopia predominant group) had no significant difference compared with the control group (p=0.60). CONCLUSIONS: Patients with moderate to severe ophthalmopathy have significant emotional distress, and severe mood disturbance especially when disfiguring signs are predominant. The psychological burden of the disease should be recognized, and routine follow-up recommended along with additional psychiatric consultation.
