Objective: The purpose of this study was to compare the differences in dentoskeletal and soft tissue changes following conventional tooth-borne rapid maxillary expansion (RME) between adolescents and adults. Methods: Dentoskeletal and soft tissue variables of 17 adolescents and 17 adults were analyzed on posteroanterior and lateral cephalograms and frontal photographs at pretreatment (T1) and after conventional RME using tooth-borne expanders (T2). Changes in variables within each group between T1 and T2 were analyzed using Wilcoxon signed-rank test. Mann–Whitney U test was used to determine the differences in the pretreatment age, expansion and post-expansion durations, and dentoskeletal and soft tissue changes after RME between the groups. Spearman’s correlation between pretreatment age and transverse dentoskeletal changes in the adolescent group was calculated. Results: Despite similar amounts of expansion at the crown level in both groups, the adult group underwent less skeletal expansion with less intermolar root expansion after RME than the adolescent group. The skeletal vertical dimension increased significantly in both groups without significant intergroup difference. The anteroposterior position of the maxilla was maintained in both groups, while a greater backward displacement of the mandible was evident in the adult group than that in the adolescent group after RME. The soft tissue alar width increased in both groups without a significant intergroup difference. In the adolescent group, pretreatment age was not significantly correlated with transverse dentoskeletal changes. Conclusions Conventional RME may induce similar soft tissue changes but different dentoskeletal changes between adolescents and adults.

BACKGROUND: Many studies have attempted to develop relatively simple and easy noninvasive measurements of atherosclerosis (NIMA), and each NIMA assesses different atherosclerotic properties. We, therefore, investigated the association between metabolic syndrome (MetS) components and different NIMAs. METHODS: This study included 1,132 Korean subjects over 20 years of age who had visited a Health Promotion Center in Korea. Carotid injury (increased carotid intima-media thickness or plaques) was evaluated by ultrasonography and arterial stiffness by brachial-ankle pulse wave velocity. The MetS components were assessed according to the Asian criteria of the American Heart Association/National Heart, Lung, and Blood Institute. RESULTS: Both arterial stiffness and carotid injury gradually deteriorated with increase in the number of MetS components. Arterial stiffness and carotid injury were associated with different MetS components, each of which had varying impact. After adjustment for all possible confounders such as age, sex, and lifestyle, elevated blood pressure (BP) was found to have the strongest association with arterial stiffness, whereas central obesity, impaired fasting plasma glucose, and elevated BP had comparable connection with carotid atherosclerosis. CONCLUSION: Individual MetS components were related with subclinical atherosclerosis in different ways. Elevated BP showed the strongest association with arterial stiffness, while central obesity, impaired fasting plasma glucose, and elevated BP showed good correlation with carotid atherosclerosis.

PURPOSE: The purpose of this study is to evaluate the changing pattern of communication skills of medical students according to length and methods of training. METHODS: We evaluated a 1-week communications training course in 2003, a 1-year course in 2004, and a 1-semester course in 2005 during development of our curriculum. We have conducted the 10-minute CPX on abdominal pain annually since 2002 to assess the clinical performance of medical students who have completed the 3rd year clerkship. We selected CPX videos that were appropriate for assessment. One hundred sixty-four videos were available (1-week didactics: 42 cases, 1-week training: 28 cases, 1-semester training: 50 cases, 1-year training: 44 cases). We developed a 10-item global rating checklist to assess communication skills. A 5-point Likert scale was used to evaluate each item (4-very likely, 0-least likely). Two expert standardized patient (SP) raters evaluated the communication skills of students independently. We analyzed the outcomes based on the training length and methods. The reliability (G coefficient) was 0.825 with 2 SPs and 1 station. RESULTS: The communication skills of students improved with practice and longer training, especially with regard to opening the interview, expressing empathy, understanding the patient's perspective, and preparing for the physical examination. Rapport-building, organization of the interview, understandable explanation, nonverbal communication, active listening and consideration during the physical examination was unchanged between durations of training. The scores for empathetic expression, active listening and understanding the patient's perspective were low across all groups. CONCLUSION: We should concentrate our efforts to improve students' skills in empathetic expression, active listening and understanding the patient's perspective.

BACKGROUND: Recently, many studies have reported that university students have been suffering from stress because of their the uncertainty of their future and employment. Eating habits have often been considered as one of health-related behaviors that may be affected by life stress. The purpose of this study was to examine the association between stress and eating habits in university students. METHODS: A cross-sectional study was designed. The subjects were 282 university students which assessed their eating habits and stresses. The total numbs of students in the study 263. Eating habits were scored using a questionnaire consisting of three categories-regularity, balance, and preference. The stress was assessed by modified Korean version of BEPSI. RESULTS: The stress score was 2.4 and the total score of eating habits was 44.2. The regularity among the domains of eating habits was 14.1, the balance score was 16.1, and the preference was 14.0. In multiple regression after adjustment with confounding variables, stress had a negative relationship with eating habits. CONCLUSION: The relationship between stress and eating habits was statistically significant, especially in regularity and balance. It is important to know not only the health status, but also the factors associated with health such as stresses and eating habits in order to improve the health status of the university students. Further research needs to uncover causality and make a generalization.

Krukenberg tumor of the ovary, originally described by Krukenberg as "Fibrosarcoma ovarii mucocellulare carcinomatodes", characterized as an infiltrative mucinous carcinoma of predominant signet-ring cell type, almost metastasize from gastrointestinal tract, is not common tumor. In recent years, we have experienced 2 cases of Krukenberg tumors on both ovaries metastasis from the stomach, and report these cases with brief review of the literatures.

An 8-year-old male was admitted because of dysphagia and substernal pain suffered while eating followed by postprandial vomiting for 2 years. He was always hungry due to postprandial vomiting and willing to eat again just after vomiting. After this meals, he used to jump up and down to shake off the substernal discomfort. A narrowing of the gastroesophageal junction was noted by esophagogram. Manometry revealed high Lower esophageal sphincter (LES) pressure (51.6mmHg), incomplete LES relaxation during swallowing, loss of esophageal peristalsis and a positive pressure of the esophageal body compared to intragastric pressure. After the 1st balloon dilatation, symptoms were much improved even though LES pressure still remained high (37.2mmHg). About 2 months after the 1st balloon dilatation, symptoms relapsed and we managed him with a 2nd balloon dilatation. Symptoms were more improved than after the 1st dilatation and LES pressure normalized as well. Since the 2nd dilatation, symptoms have not recurred for 3 years. We present an 8-year-old boy with achalasia successfully managed by the use balloon dilatation.

PURPOSE: The purpose of this study was to analyze the CT findings of hepatoblastoma before and afterchemotherapy, and to compare them with surgical and pathologic features. MATERIALS AND METHODS: Twelvehepatoblastoma patients underwent chemotherapy prior to surgery; in all cases, CT scanning was performed beforeand after chemotherapy. We reviewed the findings with special attention to changes in tumor volume, the extent andpattern of contrast enhancement, the extent of low-attenuation area in the tumor, the presence of a septum, andcalcification or ossification within the mass before and after chemotherapy. Post-chemotherapy CT findings werecompared with operative and pathologic findings. RESULTS: After chemotherapy, the volume of the tumor massdecreased in all patients, and the extent of involved segments decreased in nine(75%), the non-enhancing areawithin the mass, on the other hand, increased in nine (75%). On pre-chemotherapy CT, calcifications were detectedin seven patients(58%), and on post-chemotherapy CT, in nine (75%); the extent of calcification increased in sevenpatients. On the basis of CT findings, viable tumor and necrosis areas could not be distinguished. Massivecalcification or an osteoid mixed with loose connective tissue was noted in the mesenchymal component of thetumor; the whirling pattern of enhancement within the area of low density asen on CT scanning corresponded toosteoid mixed with loose connective tissue, which contained rich blood vessels. CONCLUSION: We describe the CTfindings of hepatoblastoma both before and after chemotherapy, highlighting the changes which occurred. Anunderstanding of these changes is helpful for the proper management of this condition.

BACKGROUND: Arterial stiffness is an important factor in atherosclerosis. Thus we examined whether aerobic exercise could reduce arterial stiffness in obese women with type 2 diabetes without diabetic complication. METHODS: A total of 35 women with type 2 diabetes (body mass index, 26.6+/-2.8 kg/m2; age, 56.4+/-1.9 years; duration of diabetes, 4.7+/-4.8 years) were assigned to aerobic exercise group (AEG) or control group (CG). AEG completed a 12-week exercise program (3.6 to 5.2 metabolic equivalents, 3 day/week, 60 min/day), with their exercise activities monitored by accelerometers. We measured abdominal total fat area (TFA), visceral fat area (VFA), and subcutaneous fat area (SFA) by computed tomography, insulin sensitivity by insulin tolerance test (K(ITT)), and augmentation index (AIx) by SphygmoCor at baseline and at the end of the 12-week program. RESULTS: The AIx was improved in the AEG compared with the CG (P<0.001). The percent change of AIx had significant correlation with the improvement of physical activity energy expenditure (PAEE), aerobic capacity, TFA, and SFA (r=-0.416, P=0.013; r=0.560, P<0.001; r=0.489, P=0.003; r=0.531, P=0.001, respectively), but not with insulin sensitivity, energy intake, or VFA. CONCLUSION: Improvement in aortic stiffness by aerobic exercise is related with the improvement of aerobic capacity, PAEE, and total fat but not with insulin sensitivity or energy intake in obese women with type 2 diabetes.
