PURPOSE: To report the clinical features and surgical results for lower lid entropion with kinked tarsus compared with entropion with weakened capsulopalpebral fascia. METHODS: From March 2008 to December 2009, 20 patients (24 eyes) with lower lid entropion were examined. The patients were divided into the aggravated entropion with kinked tarsus group or the weakened capsulopalpebral fascia group based on the height of tarsus, the shapes of the lower lid and tarsus, and conjunctiva changes. For treatment of entropion in the kinked tarsus group, full thickness tarsotomy with rotatory suture (tarsal fracture operation) was performed, and in the weakened CPF group, a CPF tight procedure was performed. The results of the operations were retrospectively evaluated. RESULTS: The mean age of the patients with entropion in the kinked tarsus group (15 cases) was 66.7 +/- 11.4 years, and the mean age of the patients with entropion in the weakened CPF group (9 cases) was 67.2 +/- 6.2 years. The height of the lower lid tarsus of each group was 3.80 +/- 0.39 mm and 5.20 +/- 0.30 mm, respectively. Except for one case of recurrence after tarsal fracture operation in the kinked tarsus group and reoperation with CPF tightening, there were no significant complications or recurrence in either group. CONCLUSIONS: Entropion with kinked tarsus was more common than entropion with weakened CPF in the present study. In addition, surgical treatment based on the shape and cause of entropion showed good results.

STUDY DESIGN: Retrospective study. OBJECTIVES: To analyze the outcomes of conservative management in elderly patients over 65 years of age who were diagnosed with pyogenic spondylitis. SUMMARY OF LITERATURE REVIEW: The surgical treatment of pyogenic spondylitis can lead to complications in elderly patients in a poor general condition or with underlying diseases. MATERIALS AND METHODS: We performed a retrospective review of 32 patients who were diagnosed with pyogenic spondylitis and had a minimum of 12 months of follow-up. Age, sex, comorbidities, clinical symptoms, and the involved segments were analyzed retrospectively. The diagnosis was assessed using clinical, laboratory, and radiologic findings. Antibiotic therapy was either specific (if positive culture results were found) or broad-spectrum cephalosporin (when the pathogenic agent was not isolated). Outcomes were assessed using residual pain and neurologic deficits. RESULTS: The mean onset time was 23.5 days (range, 3-90 days). The mean period of intravenous antibiotic therapy was 36.3 days (range, 10-90 days). All cases underwent conservative management, and 4 patients with progressive neurologic deficits due to epidural abscess underwent posterior laminectomy and abscess drainage. In all cases, the infection was successfully treated, although 12 cases reported residual lower back pain and 2 continued to exhibit minor neurologic deficits. CONCLUSIONS: In elderly patients with pyogenic spondylitis, satisfactory results were obtained with conservative management using antibiotics and orthosis after an early diagnosis, unless progressive neurologic symptom instability or spine deformities were noted.

PURPOSE: The purpose of this study is to examine the frequency of posterior element injury in patients with traumatic thoraco-lumbar burst fractures and to evaluate the correlation between the MR imaging and CT findings. MATERIALS AND METHODS: The MR images of 38 patients with 39 thoraco-lumbar burst fractures and the results of the CT examinations of 28 patients with 29 fractures were retrospectively analyzed. Both procedures were performed within two weeks of injury. Twenty-one males and 17 females were included ; their average age was 51.3 (range, 11-75) years. MR images were evaluated for injury to the posterior ligamentous complex, comprising the supraspinous ligament(SSL), the interspinous ligament(ISL), the flaval ligament(FL), and the capsule of facets. Analysis of the CT findings focused on the posterior bony elements of the lamina, pedicle, spinous process, and facet joint. RESULTS: MR imaging revealed posterior ligamentous injuries in 18(46.2%) of 39 burst fractures ; there was tearing of the ISL in 15 cases(38.5%), of the SSL in 11(28.2%), of the capsule of facets in 11(28.2%), and of the FL in nine(23.1%). Among the 29 burst fracture cases examined by CT, posterior bony injuries were detected in 13(44.8%). Lamina and facet joint fractures were detected in six cases(20.7%), facet separation or dislocation in six(20.7%), and spinous process and pedicle fracture in one(3.4%). In 29 burst fracture cases, both MRI and CT were performed. Among the 18 cases in which MR imaging revealed posterior ligamentous injuries, CT failed to demonstrate posterior element fractures in seven. On the other hand, among the 13 cases in which CT indicated posterior bony fractures, MR failed to reveal posterior ligamentous injuries in two. CONCLUSION: Posterior element injury is frequently found in patients with traumatic thoraco-lumbar burst fractures demonstrated by MR imaging(46.2%) and CT(44.8%). Both MRI and CT are useful tools for the evaluation of posterior element injury, which determines the degree of instability of traumatic burst fracture.

PURPOSE: To determine the correlation of the clinical characteristics and histopathologic findings of lacrimal sac after external dacyrocystorhinostomy (DCR). METHODS: From March 2008 to June 2009, 49 lacrimal sac tissues of 47 patients were obtained after external DCR and divided according to fibrosis and inflammatory findings. The correlation of preoperative duration of symptoms with NLD obstruction, symptoms of recurrence and outcomes of the operation to the histopathologic findings were retrospectively evaluated. RESULTS: The mean age of the patients was 58.83 +/- 11.49 years and the mean duration of preoperative symptoms was 65.2 +/- 69.05 months. Forty-three cases (88%) maintained good openings and 30 cases (61%) had no recurring symptoms over 6 months after the operation. Among the significant symptoms, severe subepithelial inflammations were observed more frequently at shorter duration. However, the fibrosis showed a positive relation with the preoperative duration of symptoms (Spearman correlation test, p<0.05). Most failures were found in the severe inflammation and fibrosis groups and were recovered with anti-inflammatory treatment. CONCLUSIONS: Inflammation and fibrosis of the lacrimal sac could be an important prognostic and predictive factor of outcomes of DCR.

PURPOSE: To evaluate injury patterns of facet joints and associated soft tissue injuries in patients withacute traumatic cervical facet joint injuries. MATERIALS AND METHODS: From among patients with cervical spinetrauma, 27 with facet joint injuries, as seen on CT and MRI, were chosen for this study. CT scans were analyzedwith regard to the location of facet joint injury, the presence or absence of facet dislocation or fracture, andother associated fractures. MR images were analyzed with regard to ligament injury, intervertebral disc injury,intervertebral disc herniation, and spinal cord injury. RESULTS: The most common location of facet joint injurywas C6-7 level(n=10), followed by C5-6(n=8). Among these 27 patients with facet joint injuries, 12(44%) hadbilateral injuries and 15(56%) unilateral injuries. Facet fractures were present in 17 cases(63%) and the fractureof inferior facet was more frequent than superi-or. Patterns of fracture were vertical, transverse, or comminuted,but vertical fracture was the most common. Various degrees of dislocation were observed in patients with facetfractures. Fractures other than facet includ-ed pillar(n=11), lamina(n=6), transverse process(n=14), body(n=13),and spinous process(n=3). On MR im-ages, anterior longitudinal ligament injury was found in 8 patients(30%),posterior longitudinal ligament injury in 4(15%), and interspinous ligament injury in 20(74%). Twelvepatients(44%) had spinal cord injuries includ-ing edema(n=8) and hemorrhage(n=4). Among patients with discabnormalities, 11(41%) had intervertebral disc injuries, and traumatic disc herniations were found in nine. CONCLUSION: Traumatic cervical facet joint injuries were manifested as various patterns and frequentlyassoci-ated with other fractures or soft tissue injuries. Analysis of CT and MR findings of these injury patternshelped formulate a therapeutic plan and determine of prognosis.

A hepatic angiosarcoma is a rare primary malignant neoplasm, which accounts for only 2% of all primary hepatic tumors. The prognosis of a hepatic angiosarcoma is very poor, and most patients die within a year of the initial diagnosis. We report a case of a hepatic angiosarcoma in a 57-year-old man. Although a dynamic CT had suggested a carvenous hemangioma 12 months earlier, the tumor size increased and spontaneously ruptured, so surgical resection was mandatory. A pathological examination, including immunohistochemical studies, showed positive staining for CD34 and Factor VIII, which confirmed the diagnosis of an angiosarcoma. Although dynamic CT is an excellent modality for the diagnosis of a cavernous hemangioma of the liver, hepatic angiosarcomas should be ruled out in selected cases, because they may present with very similar CT findings to benign hemangioma.

In this report, the patient was pre-diagnosed as meningioma before surgery, which turned out to be meningeal melanocytoma. Hence, we will discuss the interpretation of imaging and neurological statuses that may help avoid this problem. A 45-year-old man had increasing pain around the neck 14 months prior to admission. His cervical spine MR imaging revealed a space-occupying, contrast-enhancing mass within the dura at the level of C1. The neurologic examination revealed that the patient had left-sided lower extremity weakness of 4+, decreased sensation on the right side, and hyperreflexia in both legs. Department of Neuroradiology interpreted CT and MR imaging as meningiom. The patient underwent decompression and removal of the mass. We confirmed diagnosis as meningeal melanocytoma through pathologic findings. Afterwards, we reviewed the patient's imaging work-up, which showed typical findings of meningeal melanocytoma. However, it was mistaken as meningioma, since the disease is rare.

Tracheo-innominate artery fistula (TIAF) is rare, yet the most fatal complication after tracheostomy. In the absence of immediate diagnosis and surgical management, the mortality rate is very high, because the complication can lead to sudden massive tracheal hemorrhage. Tracheal obstruction and hypovolemic shock are the major life threatening conditions. The 46-year-old woman received tracheostomy tube insertion after stroke. Three months later, there was occurrence of active bleeding at the site of tracheostomy in the patient, who participated in comprehensive rehabilitation program. Immediately, the patient received an endotracheal tube insertion into the tracheostomy site and thus massive bleeding was controlled. The patient was transferred to the intensive care unit, where her breathing was maintained by mechanical ventilation. Based on computed tomography and laryngoscopy, no remarkable findings about TIAF were detected. Nevertheless, transfemoral angiography findings revealed that innominate artery made small luminal outpouching to trachea at the carotid artery and at the subclavian artery bifurcation level, based on which a diagnosis of TIAF was made. She had an operation for TIAF, tracheoplasty with bypass graft. Subsequently, she was discharged after 15 weeks. In the present report, we describe a case of TIAF, which can occur in the patients with tracheostomy tube during rehabilitation.

BACKGROUND: Since the 1960 s rabbit antihuman globulin reagent has been used widely. Recently most conjugate of enzyme immunoassay is produced from goat, and precise purification method is developed. Therefore we evaluated the commercial value of the goat antihuman globulin as a blood bank test reagent. METHODS: The human IgG was purified by protein-A gel, and injected into goat. The goat antihuman globulin was coupled by CNBr activated sepharose 4B-gel and purified by 0.2M glycine elution buffer. For verification of this reagent, commercial reagents(Ortho rabbit reagent & DiaMed Gel test) were used. RESULTS: The minimal concentration for detecting antibody of goat reagent was 9 ng/mL. The results of direct antiglobulin tests, with 400 samples collected from donated blood in CPDA-1, were all negative(false positive rate: 0%). With 613 samples collected from inpatients of Severance Hospital, the results were positive in 35 patients(positive rate:5.7%), and those results were in complete agreement with commercial reagent(concordance rate: Goat vs. Ortho :99.8%, Goat vs. DiaMed :98.4%). And with 30 samples of artificially prepared complement-coated RBC, the results were all negative. Indirect antiglobulin test showed higher agglutination score than commercial reagents. CONCLUSIONS: Goat reagent showed high sensitivity and specificity in comparison with rabbit reagent. Because false positive reaction was not observed in negative control samples, the heterophil agglutinin reaction, which was the major problem when the reagent was initially developed, might be excluded. In conclusion, goat reagent seems to be more economical than rabbit reagent because the former can be obtained in a large quantity and of high potency.
