Human diphyllobolthriasis is chiefly caused by infection with Diphyllobothrium latum(D. latum) through eating raw or unproperly cooked fish such as salmon, trout or perch. D. latum is worldwidely distributed, but not a common parasite of humans, and its prevalence in Korea is not high. The first worm-proven case of D. latum infection was first reported in 1971 and about 30 cases have been reported in Korea until now. However, with the increasing popularity of eating raw salmon, trout and perch, this tapeworm infection tends to increase in Korea. Most of the patients infected by D. latum have not showed the specific symptoms and only non-specific gastrointestinal symptoms(anorexia, nausea, vomiting, diarrhea, abdominal pain). We report a case which includes a chain whitish, threadlike tapeworm segments spontaneously discharged in the patients stool. On reviewing the literature, the present case is the first report of D. latum infection by eating cultured salmon. The patient was treated with 600mg single dose of Praziquantel.

Carpal malalignments in malunion of distal radius fracture are considered as an adaptive response of the carpus to loss of normal architecture of the distal radius. This condition leads to mechanical overload, ligament attenuation and progressive dynamic instability around the wrist joint. Radial corrective osteotomy is suggested as a treatment option of carpal malalignment after distal radius malunion. In radiocarpal malalignment, the lunate is usually observed in flexion in contrast to its extension posture in the more common midcarpal malalignment. We report two cases of fixed lunate flexion deformity after a distal radius fracture, in which reduction and fixation of fresh fracture or corrective osteotomy of malunion were not successful. Arthritic changes were observed in the radiolunate joint on arthroscopy. Thus, fixed flexion deformity of the lunate might be associated with posttraumatic arthritic change in the radiolunate joint.

The Muenke syndrome (MS) is characterized by unicoronal or bicoronal craniosynostosis, midfacial hypoplasia, ocular hypertelorism, and a variety of minor abnormalities associated with a mutation in the fibroblast growth factor receptor 3 (FGFR3) gene. The birth prevalence is approximately one in 10,000 live births, accounting for 8-10% of patients with coronal synostosis. Although MS is a relatively common diagnosis in patients with craniosynostosis syndromes, with autosomal dominant inheritance, there has been no report of MS, in an affected Korean family with typical cephalo-facial morphology that has been confirmed by molecular studies. Here, we report a familial case of MS in a female patient with a Pro250Arg mutation in exon 7 (IgII-IGIII linker domain) of the FGFR3 gene. This patient had mild midfacial hypoplasia, hypertelorism, downslanting palpebral fissures, a beak shaped nose, plagio-brachycephaly, and mild neurodevelopmental delay. The same mutation was confirmed in the patient's mother, two of the mother's sisters and the maternal grandfather. The severity of the cephalo-facial anomalies was variable among these family members.

PURPOSE: The aim of this study was to investigate the effect of implant thread profile on the marginal bone stresses which develop during implant insertion. MATERIALS AND METHODS: Four experimental implants were created by placing four different thread systems on the body (4.1 mm x 10 mm) of the ITI standard implant. The thread types studied in this study included the buttress, v-shape, reverse buttress, and square shape threads. In order to examine the insertion stress generation, 3D dynamic finite element analysis was performed which simulated the insertion process of implants into a 1.2 mm thick cortical bone plate (containing 3.5 mm pilot hole) using a PC-based DEFORM 3D (ver 6.1, SFTC, Columbus, OH, USA) program. RESULTS: Insertion stresses higher than human cortical bone developed around the implants. The level of insertion stresses was much different depending on the thread. Stress level was lowest near the v-shape thread, and highest near the square shaped thread. Difference in the interfacial bone stress level was more noticeable near the valley than the tip of the threads. CONCLUSION: Among the four threads, the v-shape thread was turned out to minimize the insertion stress level and thereby create better conditions for implant osseointegration.

PURPOSE: To evaluate the usefulness of CT features of appendiceal mucocele in the diagnosis and evaluation of complications. MATERIALS AND METHODS: We retrospectively reviewed CT findings and compared with operative findings in 7 cases of pathologically proven appendiceal mucocele. CT findings such as location and extent of the lesion, Issue density, thickness or calcification of the wall, presence of adjacent inflammatory infiltration, and visualization of normal vermiform appendix were analyzed. RESULTS: Appendiceal mucocele was found as homogeneous low density cystic mass adjacent to the cecum, which has no surrounding inflammatory infiltration except in one case of perforation and one case of intussusception. Mean CT number measured in 4 cases was 21 Hounsfield unit. Thin curvilinear calcifications were noted along the cystic wall in 2 cases. Normal vermiform appendix couldn't be demonstrated in all cases. CONCLUSION: Appendiceal mucocele is characterized by homogeneously low density and thin walled cystic tumor adjacent to cecum without surrounding inflammatory infiltration, and absence of normal vermiform appendix on CT. Therefore, CT is valuable in preventing operative complications of appendiceal mucocele.

OBJECTIVES: There are a lot of studies that analyze the interaction between the emotion of disgust and the functional brain images using fMRI and PET. But studies using sLORETA (standardized low resolution brain electromagnetic tomography) almost do not exist. The aim of this research is to explore the relationship of the emotion of disgust and the cortical activation using sLORETA analysis. METHODS: Forty five healthy young adults (27.1+/-2.6 years) participated in the study. While they were watching 4 neutral images and 4 disgusting images associated with mutilation selected from the international affective picture system (IAPS), participants' EEGs were taken for 30 seconds per one picture. Through these obtained EEG data, sLORETA analysis was performed to compare EEGs associated with neutral and negative images. RESULTS: During looking for visual disgusting stimulus, all participants reported unpleasantness, arousal and stress. In sLORETA analysis, the decrease of current density in theta wave was shown at left frontal superior gyrus (BA10) and middle gyrus (BA10, 11). This voxel cluster consists of a total of 11 voxels and the threshold of t value indicating statistically significant decreases in the current density (p<0.05) was -1.984. There were no differences between male and female in the degree of being disgusted by the stimuli. CONCLUSION: This finding may suggest that the activation of dorsolateral prefrontal cortex might be associated with regulating disgust emotion.

Among the 85 cases of prosthetic replacement of femoral neck fracture which had been operated at Department of Orthopaedic Surgery, Korea Veterans Hospital from January, 1982 to May, 1990, 32 cases (15 unipolar hemiarthroplasty and 17 bipolar hemiarthroplasty) were examined clinically and radiologically at an average 7.7 years postoperatively. And the results were as follows; 1. The group I (Unipolar hip hemiarthroplasty without cement) had Harris hip score - average 79.4. The group II (Unipolar hip hemiarthroplasty with cement) had Harris hip score average 87.3. The group III (Bipolar hip hemiarthroplasty without cement) had Harris hip score average 80.5. The group IV (Bipolar hip hemiarthroplasty with cement) had Harris hip score average 86. 2. There were 2 cases of stem loosening (13%) among 15 cases in unipolar hip hemiarthroplasty and 1 case (6%) among 17 cases in bipolar hip hemiarthroplasty. 3. The movement of two components in bipolar hip hemiarthroplasty was noted in all cases and the movement of the outer bearing joint was more active than that of the inner. And the movement of the two components was not correlated with the use of cement. But Harris hip score was superior cement stem group to noncement stem group. 4. Unipolar hip hemiarthroplasty showed the similar clinical and radiological results with bipolar hip hemiarthroplasty of femoral neck fracture in the elderly. As a result, unipolar and bipolar hip hemiarthroplasty were considered the proper treatment method of the femoral neck fracture in the elderly.

Omental torsion secondary to inguinal hernia has rarely been reported as a cause of acute abdominalpain. However, in our case, omental infarction due to prolonged inguinal hernia-associatedomental torsion led to the formation of a large omental mass with marginal fibrosis, andthe patient presented with chronic abdominal pain. A 74-year-old man presented with complaintsof lower abdominal pain for 1 month; subsequently, bilateral inguinal hernias wereidentified through inguinal ultrasonography. CT scans revealed that the greater omentum wastrapped within the right inguinal canal, leading to omental torsion. The greater omentum, distalto the pedicle, appeared as a 30 cm-sized oblong fibrofatty mass in the right lower abdomenand pelvic cavity. Laparoscopic omentectomy with hernia repair was successfully performed.
