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.

The purpose of this study was to implement and evaluate the nutrition education program for elementary school children. Subjects were 5th graders (n = 142) of an elementary school in Seoul, and 138 children completed four sessions of nutrition education during March-April, 2008. One group pretest-posttest design was used to evaluate the program effectiveness. Anthropometric measurements and measurements on nutrition knowledge, eating attitudes and eating behavior were done before and after education. Data were analyzed using paired t-test, t-test and chi-sqaretest. After completing nutrition education, body mass index (from 19.3 to 18.9), fat mass (from 10.9 kg to 10.1 kg), percent body fat (from 25% to 23.3%) of subjects decreased significantly (p< 0.001). Percentages of overweight or obese children were 24.6% at pretest and decreased to 20.3% at posttest, although it did not reach statistical significance. Total score of nutrition knowledge increased significantly from 11.9 (59.5/100) at pretest to 14.7 (73.5/100) at posttest (p< 0.001). After nutrition education, percentages of correct answers increased significantly in 10 knowledge items out of 20 items. These included items such as desirable weight control, energy requirements for boys, food groups, snack, and function of fat and balanced meals (p< 0.001). Total score of eating attitudes increased significantly from 35.1 to 36.9 (p< 0.001). Attitude of applying nutrition knowledge to daily life (p< 0.001), interest toward nutrition and health (p< 0.001), attitude of moderating food intake (p< 0.01), and attitude toward eating habit and future health (p< 0.05) were significantly different between pretest and posttest. Total score of eating behaviors increased significantly from 46.7 (possible score: 20-60) to 49.5 by nutrition education (p< 0.001). Improvement in eight eating behaviors were noticed after nutrition education. These included eating meals slowly, eat protein foods (p< 0.001), eating breakfast, eating meals regularly, eating meals with diverse foods, having dairy foods, eating foods using plant oils (p< 0.01), and having grains (p< 0.05). Subjects evaluated quite positively in attractiveness of program, understanding of program contents, helpfulness of program in improving nutrition knowledge and meal management. Study results show that the nutrition education program was effective in improving nutrition knowledge, eating attitudes and changing eating behaviors of children. This program can be used in nutrition education of children at school or at public health centers

OBJECTIVES: Many chronic schizophrenics are suffered from treatment-refractory hallucinations. As a countermeasure, the combined use of neuroleptics and benzodiazepines has been studied. In this context, the authors tried to evaluate the anti-hallucinatory effect of neuroleptics-clonazepam combination therapy. METHODS: At first, the authors described 3 cases of chronic schizophrenics who reported alleviation of hallucinations, which are resistant to neuroleptic treatment, after adding clonazepam. And then, prospective open study including 6 female chronic schizophrenic inpatients having neuroleptic-refractory hallucinations was done. In addition to existing psychiatric medication, these patients were treated with clonazepam 1.5 mg for 6weeks and evaluated at 5 points ; at baseline, and 1, 2, 4 and 6 weeks of treatment. The psychopathology was assessed by the items of hallucinatory behavior and anxiety/tension of PANSS and BPRS. Clinical improvement was defined by fall-off of the hallucinatory behavior below the moderate level. The side effects were assessed by UKU Side Effect Rating Scale. RESULTS: All patients completed 6 weeks' trial. At the end of 6 weeks, 2 (33.3%) of 6 patients showed decrement of the hallucinatory behavior below the moderate level, when evaluated by PANSS and BPRS. However, the courses of anti-hallucinatory effect were different in these 2 patients. Another one patient showed that the hallucinatory behavior assessed by BPRS fell to the moderate level, but not when assessed by PANSS. The item of anxiety/tension was unchanged in all 6 patients. Except very mild sedation in one patient, there was no side effect. CONCLUSION: This study suggests that neuroleptics-clonazepam combination therapy is effective against treatment-refractory hallucinations in some schizophrenics and generally safe.

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.

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: 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.
