When the patient with class III malocclusion needs extensive oral rehabilitation due to multiple missing teeth, accurate diagnosis, and careful analysis, such as the patient’s occlusal relationship, facial changes, and evaluation of the temporomandibular joint are essential. Orthognathic surgery is often performed for aesthetic improvement, depending on the patient’s chief complaint. If it is not possible due to certain circumstances, partial aesthetic improvement can be achieved through minimal elevation of the vertical dimension. As this patient may have unexpected issues, such as temporomandibular joint disorder, oral habits like bruxism, and masticatory muscle tension, it was determined whether the patient could adjust to a reversible temporary removable partial denture. After this, the maxillary implant-supported fixed prostheses and the mandibular fixed prostheses were used to achieve stable posterior support and to partially improve the maxillary anterior esthetics. The patient was satisfied with the results both aesthetically and functionally. The prognosis is expected to be good if regular check-ups are conducted.

Candida is a commensal organism that is frequently found in the human gastrointestinal tract. It is the most common organism that causes pancreatic fungal infections. However, magnetic resonance imaging findings of Candida infection in the pancreas have not been described. We report imaging findings of pancreatic candidiasis in a patient in immunocompetent condition. It presented as a multi-septated cystic mass with a peripheral solid component in the background of pancreatitis and restricted diffusion on diffusion-weighted image that mimicked a malignant pancreatic cystic tumor.

PURPOSE: To determine the effect of changing practice guidelines designed to avoid hyperoxia or hypoxia in very low birth weight or very preterm infants. METHODS: We analyzed a database of <1,500 g birth weight or <32 weeks of gestation infants who were born and admitted to the neonatal intensive care unit of Chungnam National University Hospital from January 2007 to July 2010. First, we defined the relationship between arterial partial pressure of oxygen (PaO2) and pulse oxygen saturation (SpO2). When we evaluated 96 pairs of PaO2 and SpO2 measurements, oxygen saturation was 90-94% at a PaO2 of 43-79 mmHg on the oxyhemoglobin dissociation curve, according to pulse oximetry. Based on this observation, a change in practice was instituted in August 2008 with the objective of avoiding hypoxia and hyperoxia in preterm infants with targeting a SpO2 90-94% (period II). Before the change in practice, high alarms for SpO2 were set at 100% and low alarms at 95% (period I). RESULTS: Sixty-eight infants the met enrollment criteria and 38 (56%) were born during period II, after the change in SpO2 targets. Demographic characteristics, except gender, were similar between the infants born in both periods. After correcting for the effect of confounding factors, the rates for mortality, severe retinopathy of prematurity, and IVH attended to be lower than those for infants in period II. No difference in the rate of patent ductus arteriosus needed to treat was observed. CONCLUSION: A change in the practice guidelines aimed at avoiding low oxygen saturation and hyperoxia did not increase neonatal complication rates and showed promising results, suggesting decreased mortality and improvements in short term morbidity. It is still unclear what range of oxygen saturation is appropriate for very preterm infants but the more careful saturation targeting guideline should be considered to prevent hypoxemic events and hyperoxia.

EBV infection has been causally associated with incidence of many carcinomas. EBV-associated gastric carcinoma (EBVaGC) has been classified as a unique gastric carcinoma subset, suggesting EBV infection is related to the development of gastric cancer. In this study, general trends of EBVaGC studies for last half-decades were reviewed in several perspectives of clinical significance, virological importance and etiological interests. Throughout this comprehensive reviewing, new study trends of EBV and EBVaGC for next half-decades were suggested.

Sturge Weber syndrome (SWS) is a rare, congenital neurocutaneous syndrome. We rarely experienced neurocutaneous disorders in forensic practice but there are unexpected sudden deaths of patients with SWS due to epilepsy, intracranial hemorrhage, thromboses and secondary accident. We introduce a case of drowning death probably due to an epileptic attack of a person diagnosed as a patient of SWS by an autopsy. We review some of the neurocutaneous syndromes and a discussion of autopsy approach is presented.

PURPOSE: As a follow-up for the validity study of Community Health Surveys (CHSs), the purpose of this study was to evaluate the factors affecting the accuracy of CHSs by investigating subjects' characteristics. MATERIALS AND METHODS: We used data from 11,217 participants (aged 19 years or older) who had participated in the CHS, conducted by a local government in 2008 and analyzed the variables affecting the sensitivity and specificity of hospitalization and outpatient visit. RESULTS: Multivariate logistic regression analysis showed that, factors related with the sensitivity of hospitalization and outpatient visit questions were gender, age, marital status, chronic diseases, medical checkup, the subjective health status and necessary medical services. Factors related with the specificity were gender, marital status, educational background, chronic diseases, medical checkup, alcohol consumption, necessary medical services and sadness. CONCLUSION: This study revealed the subject-related factors associated with the validity of the CHS. Efforts to improve the sensitivity and the specificity from self-report questionnaires should consider how the characteristics of subjects may affect their responses.

OBJECTIVES: We evaluated changes in mammographic density (MMGD) after hormone therapy (HT) using levonorgestrel (LNG) in Korean postmenopausal women. METHODS: In this retrospective study, 58 healthy postmenopausal women with no history of prior HT were included. Twenty-three women were given a cyclic regimen of estradiol valerate (E) 2 mg/day + LNG 0.075 mg/day and 25 untreated women served as a negative control and 10 women treated with continuous combined regimen of conjugated equine estrogen (CEE) 0.625 mg/day + medroxyprogesterone acetate (MPA) 2.5 mg/day as a positive control. Mammography was obtained at baseline and 1 year later, and MMGD was assessed. In addition, the change in the proportion of the dense area after HT was assessed using the J-image program. Data were analyzed with analysis of variance and chi-square or Fisher's exact test. RESULTS: There were no significant differences in baseline characteristics among three groups. After 1 year of HT, increase of BI-RADS grade in CEE + MPA group (7/9, 77.8%) was higher than in E + LNG group (2/16, 12.5%; P = 0.001). But there was no difference between untreated group (1/19, 5.3%) and E + LNG group (2/16, 12.5%; P = 0.446). In subgroup analysis of women with BI-RADS grade 3 at baseline, no significant difference. Changes in the proportion of dense areas assessed by the J-image program showed similar results. Regression analysis revealed that there was no correlation between baseline dense area and changes after HT in E + LNG group. CONCLUSION: HT using LNG did not influence MMGD in Korean postmenopausal women. Further study on breast cancer risk may be needed.

OBJECTIVE: This study examined the initial partial pressure of carbon dioxide (PCO₂) as a possible indicator of prehospital ventilation and its association with prehospital i-gel in out-of-hospital cardiac arrest (OHCA) patients. METHODS: The demographics and arrest parameters, including i-gel insertion and initial arterial blood gas analysis, of OHCA patients who visited the emergency department were analyzed retrospectively. Linear regression analysis was performed to examine the association between i-gel insertion and the initial PCO₂. RESULTS: A total of 106 patients were investigated. Fifty-six patients had prehospital i-gel insertion and 50 patients did not have a prehospital advanced airway. The initial PCO₂ was higher in the i-gel group than the no advanced airway group (105.2 mmHg [77.5–134.9] vs. 87.5 mmHg [56.8–115.3], P=0.03). Prehospital i-gel insertion was associated with a higher initial PCO₂ level (βcoefficient, 20.3; 95% confidence interval, 2.6–37.9; P=0.03). CONCLUSION: Prehospital insertion of i-gel was associated with higher initial PCO₂ values in OHCA patients compared to no advanced airway.

Artemisia annua is a wormwood. Because it may induce Cytochrome P450 2C19 enzyme, Artemisia annua may have an influence on antiepileptic drugs which are substrates for the enzyme. This influence may negatively affect seizure control of epilepsy patient. We present a patient whose seizures were induced by Artemisia annua, despite he was taking levetiracetam which is not a substrate for the hepatic enzyme. Therefore there would be another mechanism of seizure induction of Artemisia annua besides hepatic metabolism.
