Purpose:
A case of a huge ethmoid sinus and orbital cyst causing ocular deviation initially diagnosed as a mucocele-like cyst and after orbitotomy eventually discovered to be a naso-orbital encephalocele is described.Case summary: A 5-year-old male with no previous medical history presented with a palpable mass in the medial canthus area with left exodeviation of the left eye. His best-corrected visual acuity was 20/25 in the right eye and 6/12 in the left eye with limitation of motion of -4 at adduction in the left eye. Brain magnetic resonance imaging scans revealed a 3.0 × 2.5 × 2.5 cm-sized cystic mass suspected as a mucocele or nasolacrimal duct cyst invading the orbital space. The cyst was removed using a Lynch and caruncle incision, and intracystic fluid was aspirated. During the excision, a small defect of the skull base was detected with cerebrospinal fluid (CSF) leakage and leaking point of dura was sealed. His pathologic result was disorganized glial and fibrous tissue, consistent with encephalocele. Three days later, CSF leakage recurred. On postoperative day 8, duroplasty was performed. A one month later, his best-corrected visual acuity was 6/12 in the left eye with orthotropic eye position. Limitation of motion was improved to -1 at adduction with enophthalmos. No other complications were detected.
Conclusions
Congenital naso-orbital encephalocele invading the orbit is rare. However, a cystic mass in the sinuses involving the orbit should be considered, rendering thorough physical and radiologic examinations including computed tomography scans necessary to look for bone defects.

Brown tumor is a histologically benign lesion that is a serious complication of renal osteodystrophy because it may result in severe deformity and discomfort. We report a case of brown tumor, which occurred in a 35-year-old woman with chronic renal failure, who had been treated with hemodialysis for 14 years. The lesion was found on the lingual side of the mandible. Standard panoramic radiograph showed generally decreased bone mineral density, loss of lamina dura, and thin cortical plates. Computed tomography (CT) revealed multilocular expansile lesions with heterogeneous attenuation in the anterior mandible, as well as generalized trabecular alteration with homogeneous sclerosis, and thinning or obliteration of cortical plates. Excision of the mandibular lesion and curettage of the affected bone were performed.

Rhabdomyosarcoma (RMS) is an aggressive and fast-growing malignant tumor. RMS predominantly arises in the head and neck of infancy and children. Metastasis is usually via the blood vessel. We report a case of a recurred RMS of the tongue base with the metastasis to multiple lymph nodes in a 37-year-old female. On the follow-up examination using advanced imaging modalities after surgical treatment of RMS, the lymph nodes should be carefully evaluated like in other malignancies, such as a carcinoma, showing frequent lymph node metastasis.

PURPOSE: This study was performed to examine the effects of image filter on observer performance by counting the number of holes at each wedge step on a radiographic image. MATERIALS AND METHODS: An aluminum step wedge with 11 steps ranged in thickness from 1.5 mm to 16.5 mm in 1.5 mm increments was fabricated for this study. Each step had 10 notched holes with 1.0 mm diameter on the bottom of the step wedge which were ranged in depths from 0.1 mm to 1.0 mm in 0.1 mm increments. Digital radiographic raw images of the aluminum step wedge were acquired by using CCD intraoral sensor. The images were processed using several types of noise reduction filters and kernel sizes. Three observers counted the number of holes which could be discriminated on each step. The data were analyzed by ANOVA. RESULTS: The number of holes at each step was decreased as the thickness of step was increased. The number of holes at each step on the raw images was significantly higher than that on the processed images. The number of holes was different according to the types and kernel sizes of the image filters. CONCLUSION: The types and kernel sizes of image filters on observer performance were important, therefore, they should be standardized for commercial digital imaging systems.

BACKGROUND: This study aimed to evaluate the efficacy and safety of sodium-glucose cotransporter-2 (SGLT2) inhibitors in Korean patients who had inadequately controlled type 2 diabetes mellitus (T2DM) in real-world clinical practice. METHODS: We included 410 patients who started SGLT2 inhibitors (empagliflozin or dapagliflozin) as add-on therapy or switch therapy between February 2015 and June 2017. The primary efficacy endpoint was a change in glycosylated hemoglobin (HbA1c) from baseline to week 12. The secondary endpoints were patients achieving HbA1c <7.0% and changes in the fasting plasma glucose (FPG), lipid profiles, body weight, and blood pressure (BP). RESULTS: The mean HbA1c at baseline was 8.5% (8.6% in the add-on group and 8.4% in the switch group). At week 12, the mean adjusted HbA1c decreased by −0.68% in the overall patients (P<0.001), by −0.94% in the add-on group, and by −0.42% in the switch group. Significant reductions in FPG were also observed both in the add-on group and switch group (−30.3 and −19.8 mg/dL, respectively). Serum triglyceride (−16.5 mg/dL), body weight (−2.1 kg), systolic BP (−4.7 mm Hg), and diastolic BP (−1.3 mm Hg) were significantly improved in the overall patients. Approximately 18.3% of the patients achieved HbA1c <7.0% at week 12. A low incidence of hypoglycemia and genital tract infection was observed (6.3% and 2.2%, respectively). CONCLUSION: SGLT2 inhibitors can be a suitable option as either add-on or switch therapy for Korean patients with inadequately controlled T2DM.

PURPOSE: This study compared nursing frequency, nursing time, and nursing intervention priorities depending on the method of neonatal induced hypothermia. METHODS: We observed 15 neonatal subjects receiving therapeutic hypothermia for 3 days each. Forty-five nurses experienced with nursing neonatal patients under therapeutic hypothermia provided responses about nursing intervention priorities. Analyses with the chi-square, the Fisher exact test, the paired t-test, the Wilcoxon signed rank test, and the Wilcoxon rank-sum test were performed on the data using SAS version 9.4. RESULTS: The frequency of nursing activities was higher for selective head therapeutic hypothermia (SHTH) than for systemic therapeutic hypothermia (STH), and nursing time was also significantly longer. In terms of nursing intervention priorities, there were priority differences in “risk for ineffective thermoregulation” and “risks for impaired skin integrity” for SHTH compared to STH . CONCLUSION: Since SHTH for neonatal therapeutic hypothermia requires more nursing time and frequent nursing activities than STH, STH is therefore recommended if the therapeutic efficacy is similar. Appropriate nursing personnel should be allocated for neonatal SHTH nursing. Nurses should be aware of nursing interventions for therapeutic hypothermia as the priorities are different for different methods of neonatal therapeutic hypothermia.

OBJECTIVE: To develop the Korean version of the Kessler Foundation Neglect Assessment Process (KF-NAP), which enables a more functional assessment of unilateral spatial neglect, by first translating it into Korean and then statistically standardizing it. METHODS: Two rehabilitation specialists translated the KF-NAP into Korean. The entire process of administering the Korean KF-NAP to 30 patients with brain disease was video-recorded. Five occupational therapists from 4 university hospitals nationwide evaluated the 30 video-recorded examination cases. We analyzed inter- and intra-reliabilities of the Korean KF-NAP using the intraclass coefficient and Pearson correlation coefficient. Internal consistency reliability of the assessment categories was also examined using Cronbach's alpha coefficient. RESULTS: For the construct validation study, the Korean KF-NAP was strongly correlated with the Albert's test and letter cancellation test (r ≥ 0.8; p < 0.05). The intraclass correlation coefficients for the first and second assessments of the Korean KF-NAP were 0.973 and 0.982, respectively, showing high reliability (p < 0.05). The intra-rater reliabilities exceeded 0.9 (p < 0.05), and Cronbach's alpha coefficient exceeded 0.8, showing internal consistency reliability. CONCLUSION: The Korean KF-NAP is a reliable and valid instrument for assessing hemispatial neglect symptoms in patients with brain diseases.

OBJECTIVES: The purpose of this study was to evaluate the effectiveness of a seniors' oral health promotion program for establishing a cooperation model between public and private sectors. METHODS: This study was carried out targeting the seniors frequenting a community center in the Sosa-gu district of Bucheon-si in the Gyeonggi-do province of South Korea. Data were obtained from self-administered questionnaires or personal interviews with elders after they participated in the oral health promotion program. Their perceived satisfaction with their oral health before and after the oral health program was compared. The data were analyzed by t-tests, ANOVA, paired t-tests, and logistic regression using SPSS to assess the effects of explanatory factors on the seniors' satisfaction of the oral health promotion program. RESULTS: In total, 22.7% of participants had a positive idea about the oral health promotion program before their participation. The mean score of change in and difference of satisfaction with oral health tended to increase in each of the following groups: women, aged 80-84 years, number of permanent teeth, full denture wearers, and those who did not require dentures. Satisfaction notably increased 0.4 points in the group of full denture wearers (P<0.05). Moreover, after 1 month, the satisfaction level of the subjects who participated in the oral health promotion program increased 5.2 times (95% CI, 1.04-25.49) compared to dissatisfaction levels. Ultimately, satisfaction with oral health shows a major impact on the satisfaction with an oral health promotion program. CONCLUSIONS: The subjects who received the oral health promotion program responded very positively, but this program needs overall consideration about work processes and further reliable evaluations.

PURPOSE: This study was designed to evaluate the efficacy and utility of panoramic radiograph for the improvement of the periodic oral examinations. MATERIALS AND METHODS: Clinical examinations and panoramic examinations were done for the 242 subjects of oral examinations. The results of panoramic radiograph interpretation were compared with the clinical findings. Two questionnaires were created. One was carried out before the panoramic examination and the other done afterwards, to find out the subjects' cognition and satisfaction for the clinical and panoramic examinations. RESULTS: 1. Panoramic findings showed a higher detection rate of 31.9% for periodontal diseases, and 23.1% for dental caries than clinical findings. CONCLUSION: The panoramic examination was revealed to improve the effectiveness of the periodic oral examination and to increase the satisfaction of the subjects of examination.

PURPOSE: The research was performed to predict the three dimensional relationship between the impacted mesiodens and the maxillary central incisors and the proximity with the anatomic structures by comparing their panoramic images with the CT images. MATERIALS AND METHODS: Among the patients visiting Seoul National University Dental Hospital from April 2003 to July 2007, those with mesiodens were selected (154 mesiodens of 120 patients). The numbers, shapes, orientation and positional relationship of mesiodens with maxillary central incisors were investigated in the panoramic images. The proximity with the anatomical structures and complications were investigated in the CT images as well. RESULTS: The sex ratio (M : F) was 2.28 : 1 and the mean number of mesiodens per one patient was 1.28. Conical shape was 84.4% and inverted orientation was 51.9%. There were more cases of anatomical structures encroachment, especially on the nasal floor and nasopalatine duct, when the mesiodens was not superimposed with the central incisor. There were, however, many cases of the nasopalatine duct encroachment when the mesiodens was superimpoised with the apical 1/3 of central incisor (52.6%). Delayed eruption (55.6%), crown rotation (66.7%) and crown resorption (100%) were observed when the mesiodens was superimposed with the crown of the central incisor. CONCLUSION: It is possible to predict three dimensional relationship between the impacted mesiodens and the maxillary central incisors in the panoramic images, but more details should be confirmed by the CT images when necessary.
