Component fixation on the acetabular side is not as much of a problem because of the simpler geometry and loading configuration. It is generally accepted that hemispheric component design is preferable and immediate implant stability can be achieved by using screws or spikes in the porous coated implants. The authors reviewed 130 primary noncemented porouscoated, press fit acetabular component in 110 patients; 84 were AML (Anatomical Medullary Locking) and 46 were HarrisGalante acetabular component. Radiologic analysis at a minimum of 3 years(average 4.5 years) was done with special regards to the vertical and medial migration, screw size and numbers, change of the radiolucent line and its zone with its fate and acetabular cup angles on the acetabular component by the 2 observers. Progressive radiolucent line at the component-bone intersurface were found in 14 cases(11%), frequently located in zone I and zone I & II. No significant vertical, medial migration and change of the acetabular cup angle were found. No screw and spike failure had occurred. No component had to be revised because of loosening. As a whole, in our 3-years experience we report excellent results with porous coated acetabular component although it dose not ensure long-term sucess.

PURPOSE: Controversy still exists over in the prognostic significance of microscopic tumor cell dissemination in patients with cancer. This study evaluated the prognostic implication of isolated tumor cells in the bone marrow of patients with gastric cancer. MATERIALS AND METHODS: Four hundred nineteen (419) patients who underwent surgery for gastric cancer between June 1998 and July 2000 were enrolled in the study. Bone marrow aspirate was obtained from the iliac crest before removal of the primary tumor. Mononuclear cells were isolated and stained with AE-1/AE-3 PAN-CYTOKERATIN. RESULTS: Cytokeratin-positive cells were found in the bone marrow of 219 patients (52.3%). The incidence varied significantly with the depth of invasion (P=0.021) and the stage (P=0.026). The five-year survival rate of patients with cytokeratin-positive cells was 74.1% and that of patients without cytokeratin-positive cells was 81.1% (P=0.2481). There were no significant differences in the recurrence rate and the site of recurrence according to whether or not cytokeratin-positive cells were present in the bone marrow. CONCLUSION: The presence of cytokeratin-positive cells in the bone marrow of patients with gastric cancer did not predict outcome and recurrence. Therefore, it cannot be used as a prognostic factor.

Ulnar neuropathy around the elbow in patients with rheumatoid arthritis can occur by synovial invasion, flexion contracture or valgus deformity of the elbow. However, attritional rupture of the ulnar nerve by medial osteophyte with synovial invasion of the rheumatoid elbow is extremely rare. We reported a case of attritional rupture of the ulnar nerve by medial osteophyte in 62 years-old male with rheumatoid arthritis. Exact diagnosis and proper treatment are required if symptoms of ulnar neuropathy present in rheumatoid arthritis with contracture and valgus deformity of the elbow.

Juvenile Paget's disease (JPD) is a rare skeletal disorder that's characterized by bone demineralization and elevated levels of serum alkaline phosphatase. JPD involves the paranasal sinuses in extremely rare cases. We report here on a 25-month-old Asian male who was diagnosed of JPD associated with aplasia of the paranasal sinuses, but not the ethmoid sinuses. The patient was successfully treated by surgery and we undertook no medical intervention. This appears to be the first reported case of JPD associated with bilateral paranasal sinus aplasia.

We have experienced a case of incomplete congenital duodenal diaphragm with a foreign body (a button), which was found by endoscopy in a 13 month-old girl. She had symptoms of hematemesis, vomiting and bloody stool for a day probably due to foreign body impaction.

Although laparoscopic surgery has been adopted for the treatment of peritonitis since the time laparoscopy was introduced for emergency operations, a laparoscopic Hartmann's procedure has not been described. We report on a Hartmann's procedure and its reversal for the treatment of peritonitis from colonic perforation by laparoscopic surgery. A 43-year-old female was diagnosed with fecal peritonitis due to a colonic perforation in the rectosigmoid colon. Five trocars were used and a Lapdisc(R) (Hakko medical, Japan) was placed at the previous Phannelstiel incision site. One hundred sixty minutes were needed for the laparoscopic Hartmann's procedure following peritoneal lavage. An oral diet was started at the postoperative 6th day and the patient was discharged on the 20th day with complete recovery. Hartmann's reversal was laparoscopically performed 3 months later. A Lapdisc was placed at the colostomy site following colostomy take-down. Four trocars were inserted at the same area as the first operation. The operative time was 180 minutes. There were no postoperative complications.

Lymphatic malformation is a congenital abnormality of the lymphatic system, which manifests frequently at birth or before 2 years of age. Lymphatic malformations are classified as macrocystic or microcystic. Microcystic lesions typically occur above the level of mylohyoid muscle and need conservative treatment rather than surgical resection because of the high rate of incomplete excision and recurrence. We report our experience with two cases of radiofrequency ablation of lymphatic malformation in the oral cavity recently seen in our practice.

BACKGROUND AND OBJECTIVES: Enophthalmos is a common sequelae of orbital fracture. Moreover, it is difficult to treat secondarily. We assessed the effect of filling up the orbital volume defect with implants on the correction of late posttraumatic enophthalmos. SUBJECTS AND METHOD: Based on patients' clinical data, we retrospectively reviewed 11 patients who had an operation because of late posttraumatic enophthalmos from July 2001 to December 2005. To correct late posttraumatic enophthalmos, porous polyethylene (Medpor(R)), Medpor(R) enophthalmos wedge implant, absorbable mesh, bone graft particulate, rib cartilage, auricle cartilage, and maxilla anterior wall were used. RESULTS: Among 11 patients, 6 patients were men and 5 patients were women. The average age was 33.2 years with the follow-up period of 21.8 months. Five patients had orbital floor fracture, 1 patients had medial orbital wall fracture, 4 patients had a combination of orbital floor and medial orbital wall fractures, and 3 patients had zygoma fracture. Excellent results were obtained in all 5 patients with diplopia. The amount of enophthalmos corrected was between 1 and 5 mm (mean 2.5 mm). There was no case of visual loss, infection, migration, or exposure of implant, but we carried out re-operation on 1 case due to over reduction. CONCLUSION: Filling up the volume defect with proper implants is a relatively simple, safe and efficient technique in correcting late posttraumatic enophthalmos.

This study was designed to investigate the expression and production of interleukin-1beta (IL-1beta) in human peripheral blood of trained runners and untrained controls after temporary moderate intensity exercise. Male long-distance trained runners (TR) and untrained sedentary control subjects (SED) ran for 1 h at 70% of heart rate reserve (HRR). IL-1beta gene and protein expressions were significantly higher in TR than those with SED at all 3 intervals examined independently. Significant increases in total sweat volume and oral temperature were observed after exercise in both groups, however, there were some differences between the groups. We conclude, therefore, that sweating due to exercise is associated with increase of IL-1beta and it is correlated with decrease of oral temperature.

BACKGROUND AND OBJECTIVES: This study was performed to evaluate the clinical usefulness of the carotid intima-media thickness (IMT) as a screening test for coronary artery disease (CAD), and evaluate the differences in the carotid IMT in CAD patients with age- and sex-matched healthy subjects and hyperlipidemic hypertensive patients. SUBJECTS AND METHODS: The study was conducted on a total of 609 subjects; 229 patients with CAD (mean age; 53 yrs, 148 males), 207 age- and sex-matched hyperlipidemic hypertensive patients (mean age; 52 yrs, 115 males) and 173 age and sex matched healthy subjects (mean age; 52 yrs, 100 males). The carotid IMT was semi-automatically measured using high-resolution ultrasound. The clinical variables and carotid IMT in the study subjects were compared, and the data analyzed. RESULTS: The mean carotid IMT in patients with CAD (0.87+/-0.19 mm) was significantly higher than that in hyperlipidemic hypertensive patients (0.72+/-0.14 mm, p<0.001) and the healthy subjects (0.66+/-0.11 mm, p<0.001). Also, the carotid IMT in the hyperlipidemic hypertensive patients was significantly higher than that in the healthy subjects (p=0.001). The prevalence of carotid plaques was also significantly different between the CAD, hyperlipidemic hypertensive and healthy groups; 29.3, 18.4 and 8.7%, respectively (p<0.001). The cutoff values for differentiating CAD patients from healthy subjects and hyperlipidemic hypertensive patients were both 0.754 mm, with sensitivities and specificities of 72 and 80% and 72 and 66%, respectively, inform an ROC curve analysis. CONCLUSION: The carotid IMT was more increased in patients with coronary artery disease than in the hyperlipidemic hypertensive patients and healthy subjects. Therefore, the cutoff value (0.754 mm) of the carotid IMT could be a clinically useful screening test for predicting significant CAD and for differentiating high risk patients.
