The incidence of anterior cruciate ligament (ACL) injuries among female ballet dancers is much lower than among female soccer players, there is currently little research examining the landing error scoring system (LESS) of female ballet dancers and female soccer players. The purpose of this study was to investigate the LESS during drop vertical jump on ACL injury risk factors in female ballet dancers and female soccer players. Thirteen professional female ballet dancers and elite female soccer players participated in the study. Independent sample t-test was used to compare the LESS score between the groups with Bonferroni collection. The elite female soccer player group showed significantly higher stance width-wide, foot position-toe out, symmetric initial foot contact, overall impression and total LESS score than those of the professional ballet dancers.

PURPOSE: To describe the usefulness of small bowel enteroclysis using a hemodialysis blood pump. MATERIALS AND METHODS: Over a 16 month period, 135 double contrast small bowel enteroclysis examinations were performed in132 patients using a hemodialysis blood pump. Following intubation of the proximal jejunum, barium at a dilutionof 50% and 0.5% methylcellulose were infused at a constant rate using a hemodialysis blood pump and multiple spotfilms of the small intestine were obtained. Success rate, quality of radiographs, positive findings, fluoroscopitime and complications were evaluated. RESULTS: Only two of 135 examinations (1.5%) failed due to lack ofcooperation by the patient. Rates of good distensability were 97.6% in the proximal portion, 91.2% in the minportion and 52% in the distal portion and rates of good transparency were 96%, 84% and 56% respectively.Transparency and distensability of the small intestine were better in proximal than distal small bowel. Theradiographs showed positive findings in 25% of cases. The mean fluoroscopic time was 21 min, 10 sec(8min,22sec-57min, 30sec). No major complication was found during or after exam ination. CONCLUSION: It spite of thelong fluoroscopic time and invasiveness, double contrast small bowel enteroclysis is useful for the evaluation ofsmall bowel disease. The infusion of barium and methylcellulose using a hemodialysis blood pump give radiographsof good quality.

BACKGROUND: We identified virulence genes in uropathogenic E. coli isolates and studied the association between virulence gene and clinical characteristics in order to predict the severity and recurrency. METHODS: 39 Escherichia coli strains from patients with urinary tract infection were clinically and genotypically characterized. The strains were examined genotypically by using the multiplex polymerase chain reaction for presence of 5 urovirulence genes : pyelonephritis-associated pili(pap), S. fimbriae(sfa), afimbrial adhesin(afa), cytotoxic necrotizing factor (cnf), and alpha-hemolysin(hly). The patient's clinical characteristics were determined retrospectively. RESULTS: 17 pap(+), 4 sfa(+), 7 afa(+), 6 cnf(+), and 8 hly(+) strains were identified. And there were 10 genotypes. Among them, genotype pap(+)sfa(-)afa(-)cnf(-) hly(-) was most dominant(36%). But no urovirulence gene was detected in 12 strains(31%). When the data was analyzed, it was apparent that an association among various urovirulence genes exists. sfa gene was frequently associated with cnf gene(p < 0.001). And afa gene was associated cnf and hly gene(p= 0.026, <0.001). An association between cnf gene and hly gene was observed(p=0.002). Positive rates of virulence genes were not different between male and female. In infancy, pap(-)sfa(-)afa(+)cnf(+)hly(+) genotype was dominant. In 2-15 years old age group, pap(-) sfa(-)afa(-)cnf(-)hly(-) genotype was dominant. And in 16- 40 years old age group, pap(+)sfa(-)afa(-)cnf(-)hly(-) was dominant. So, some virulence genotype might be associated with specific age group. Presence of virulence gene or specific genotype was not different among diseases(acute pyelonephritis, cystitis, asymptomatic bacteriuria). So, virulence genes were not associated with severity of urinary tract infection. Virulence genes were not associated with susceptibility of recurrent infection. In neurogenic bladder patients, there were significantly more sfa(+) strains (p=0.019). And all isolates of neurogenic bladder patients were genotype pap(+)sfa(+)afa(-)cnf(+)hly(-)(p < 0.001). CONCLUSION: In this study, We found which genotype is most dominant in uropathogenic Escherichia coli, and that virulence genes do not suggest severity or recurrency of urinary tract infection. In neurogenic bladder patients, some virulence genes were more prevalent.

Malignant tumors of the appendix are rare and are histologically similar to those arising elsewhere in theintestines. The frequency of specific tumor types and the clinical presentation of symptomatic tumors are,however, significantly different. Before surgery, correct diagnosis of a malignant appendiceal tumor is rare; mosttumors are diagnosed by a pathologist while examining an appendectomy specimen. With the advent of high resolutionimaging modalities (ultrasound and helical CT), malignant tumors of the appendix may be more accurately diagnosed;this report describes the imaging findings of malignant appendiceal tumors.

The aim of this study was to analyze in depth the standardized Clinical dental hygiene curriculum of the Fones School in the United States. We investigated the clinical dental hygiene curriculum in 2015~2016 including title, credit, hours, contents, goals, competencies, and evaluation. We obtained the course syllabus and data related to each subject, for each grade, from the professors and students at the university. The goals and competencies, of the clinical dental hygiene program, which were based on the goals of the Fones School and the mission of the University of Bridgeport, were developed in accordance with the dental hygienist practice standards proposed by the American Dental Hygienists Association. The curriculum consisted of theory to teach proper dental hygiene care procedures and incorporated practical exercises that modeled an actual clinical setting. The students had to document the procedures performed for each client/patient and improve their clinical competency through discussion with the professors. Dental hygiene care should be provided for children, adolescents, adults, elderly, and patients, which includes patients with moderate or severe periodontal status. Students were evaluated by a paper test or case study presentation and their clinical evaluation was based on their clinical competency. In particular, professors evaluated students on a rotational basis, so they could evaluate the level of achievement of clinical competency of all students and find ways to improve any weaknesses. Therefore, the current study suggested that clinical dental hygiene program in Korea could be improved if based on the curriculum of Fones School in the United States.

Midgut volvulus is commonly complicated with malrotation, and develops mainly in infants before 1 year old, especially in neonate. Intrauterine midgut volvulus is an extremely rare disease therefore is difficult to diagnose. Furthermore unless the fetus has malrotation, symptoms and results of tests suspicious of fetal midgut volvulus are nonspecific. There are some reports that meconium ileus could be a cause of intrauterine midgut volvulus from foreign countries, however has never been reported in Korea. So we report a case of prematurity born with bowel perforation and gangrene due to intrauterine midgut volvulus caused by meconium ileus.

A 39-year-old man was admitted to our hospital because of an intermittent, epigastric, abdominal pain and abdominal bloating. Magnetic resonance Cholangiopancreatography (MRCP) showed a 4x6 cm sized heterogenous cystic mass in the hilum of the liver. The mass seemed not to have originated from the liver, but was rather located at the anterior portion of the inferior vena cava and the caudate lobe, and superior to the head of the pancreas. The common bile duct (CBD) was displaced laterally by the mass, but the other biliary tree was normal. A presumptively diagnosed hematoma or high- protein mucous component filled cystic mass was later proved to be a large mass located in the hepatoduodenal ligament on laparotomy, and was completely removed by meticulous dissection. The histopathological diagnosis confirmed an epidermoid cyst.

Primary hepatic lymphoma is a rare disorder representing less than 1% of all extranodal lymphomas. Histological examination of a primary hepatic lymphoma usually reveals a diffuse large B-cell lymphoma; there have been few reports of primary hepatic mucosa-associated lymphoid tissue (MALT) lymphomas. A 67-year-old man was being treated for a duodenal ulcer; while receiving therapy for the ulcer, a liver mass was incidentally found on abdominal ultrasonography. The pathologic diagnosis of the hepatic mass was an extranodal marginal zone B-cell lymphoma of MALT. The patient underwent radiotherapy with a total of 4,140 cGy delivered. The patient achieved complete remission and has been followed for 6 years with no recurrence of the disease. This report reviews the case of a primary hepatic extranodal marginal zone B-cell lymphoma of MALT successfully treated by radiotherapy alone.

PURPOSE: We investigated current dispatcher education requirements and proposed how to further improve and develop the EMD education curriculum in Korea. METHODS: The contents of EMD training programs from the US were used in the development of the questionnaire used to investigate the status of EMD education in Korea. The Delphi method was used to obtain expert consensus on which specific training objectives to include, how many hours would be required, who was qualified to receive the training, and how to confirm their successful qualification. RESULTS: A consensus of the experts was made for core educational objectives, the appropriate number of education hours, qualifications for trainers, passing marks for the exams, and the format of re-education as follows: The didactic education time requirement was 18 hours and the experiential education time requirement was 10 hours. The target qualification requirement for trainees was EMT level 1, and they were required to have an experience of firstaid as a prerequisite. The minimum annual re-education time was 8 hours (61.1%). The passing mark for examinations was 70.0 (median, IQR: 65.0 - 70.0) for the didactic test and 70.0 (median, Interguatile range [IQR]: 60.0 - 80.0) for the experiential test. The format of the required re-education included both comprehensive and individual forms. CONCLUSION: We propose the core contents of EMD education should be based on the results of the expert consensus.
