The complications of Salter's innominate osteotomy in the treatment of congenital dislocation of the hip were avascular necrosis of the femoral head, hematoma, rotation of distal pelvic fragment, infection, fracture of femoral shaft and redislocation. Among them the causes of redislocation were technical failure, immobilization failure and absorption the bone graft, etc. We experienced a case of redislocation after open reduction and Salter s innominate osteotomy in congenital dislocation of the hip which was induced by a foreign body reaction to the suture material.

Osteoporosis has been described as the most common disease in the old age group. As the bone mineral density decreases, the skeleton becomes more prone to fracture. Hip fractures occur late in life following substantial reduction in skeletal mass. So the incidence of hip fracture is increasing due to prolongation of average life span. The bone density of femoral neck, Ward triangle, and trochanteric region were measured by dual energy x-ray absorptiometry (DEXA) in 15 patients with femoral neck fractures and in 58 patients with intertrochanteric fractures to evaluate the relationship between bone mineral density (BMD) value and fracture type. The results were as follows 1. In femoral neck fracture group, the mean BMD value was 0.59+/-0.02 g/cm2 in femoral neck, 0.38+/-0.08 g/cm2 in Ward triangle and 0.48+/-0.09 g/cm2 in trochanteric region. In intertrochanteric fracture group, the mean BMD value was 0.57+/-0.09 g/cm2 in femoral neck, 0.39+/-0.10 g/cm2 in Ward triangle, and 0.47+/-0.13 g/cm2 in trochanteric region. 2. In femoral neck fracture group, the fracture threshold value was 0.75 g/cm 2 in femoral neck, 0.60 g/cm2 in Ward triangle and 0.67 g/cm2 in trochanteric region. In intertrochanteric fracture group, the fracture threshold value was 0.63 g/cm2 in femoral neck, 0.51 g/cm2 in Ward triangle, and 0.57 g/cm2 in trochanteric region. In conclusion, there was no statistical relationship in BMD value between neck fracture and intertrochanter fracture group, and no statistical relationship between BMD value and each fracture type in femoral neck and intertrochanter fracture. The type of hip fracture may be related to the degree of trauma rather than the value of the BMD.

Ossifications of the ligamentum flavum(OLF) and the posterior longitudinal ligament(OPLL) are uncommon clinical entities as a cause of the progressive compression myelopathy or radiculopathy. Although there are considerable literatures concerning OPLL or OLF in cervical and thoracic spine, there are only a few references about OPLL or OLF in the lumbar spine. OLF and OPLL have been reported that they may lead to severe complication only with a minor trauma or even without trauma, such as paraplegia. The authors have experienced 2 cases of OLF accompanied by OPLL In the lumbar spine, who were treated with decompressive laminectomy and excision of ossified ligaments. For its rarity of OLF and OPLL in the lumbar region, we report here with review of literature.

PURPOSE: To evaluate the correlation between diabetic macular edema diagnosed with stereoscopic slit-lamp and retinal thickness analyzer (RTA). METHODS: Diabetic macular edema diagnosed with stereoscopic slit-lamp was compared to indices of RTA in 50 eyes of 32 persons which were diagnosed clinically with diabetic retinopathy. RESULTS: From stereoscopic slit-lamp results, diabetic macular edema was present in 39 of 50 eyes, and absent in 11 of 50. Foveal average thickness out of the RTA indices was 209.7+/-58.5 micrometer from observing diabetic macular edema clinically and 199.4+/-47.3 micrometer from not observing diabetic macular edema clinically. Statistically significant differences were found in average foveal thickness between the 2 groups (p=0.013). CONCLUSIONS: RTA appears to serve as a useful and sensitive tool for the diagnosis of diabetic macular edema.

PURPOSE: To introduce a new convenient and accurate method to measure the angle kappa using ultrasound biomicroscopy (UBM) and corneal topography. METHODS: Data from 42 eyes (13 males and 29 females) were analyzed in this study. The angle kappa was measured using Orbscan II and calculated with UBM and corneal topography. The angle kappa of the dominant eye was compared with measurements by Orbscan II. RESULTS: The mean patient age was 36.4 ± 13.8 years. The average angle kappa measured by Orbscan II was 3.98°± 1.12°, while the average angle kappa calculated with UBM and corneal topography was 3.19°± 1.15°. The difference in angle kappa measured by the two methods was statistically significant (p < 0.001). The two methods showed good reliability (intraclass correlation coefficient, 0.671; p < 0.001). Bland-Altman plots were used to demonstrate the agreement between the two methods. CONCLUSIONS: We designed a new method using UBM and corneal topography to calculate the angle kappa. This method is convenient to use and allows for measurement of the angle kappa without an expensive device.

The clinicopathological manifestations of gastric mucormycosis range from colonization of ulcer disease to infiltration of tissue with or without vascular involvement. The prognosis of this disease is extremely poor when blood vessel invasion is observed. Herein, we report on a rare case of ischemic gastric perforation that was associated with vascular invasive mucormycosis in a renal recipients 7 years after transplantation.

PURPOSE: Small-for-size syndrome (SFSS) is a major problem in liver surgery, and splenectomy has been used to prevent SFSS. However, it is unknown whether splenectomy has the same effect on liver regeneration in both standard and marginal hepatectomy. The aim of this study is to see a difference in effect of splenectomy on liver regeneration according to the amount of liver resection. METHODS: Thirty male Sprague-Dawley rats (220 to 260 g) were divided into the following five groups: control (n = 6), 70% hepatectomy (n = 6), 70% hepatectomy with splenectomy (n = 6), 90% hepatectomy (n = 6), and 90% hepatectomy with splenectomy (n = 6). The animals were euthanized 24 hours after surgery and liver specimens were obtained. To assess liver regeneration, we performed immunohistochemistry of liver tissue using 5-bromo-2-deoxyuridine (BrdU) labeling and Western blot analysis of hepatic growth factor (HGF) and transforming growth factor-beta (TGF-beta) in the liver tissue. RESULTS: The splenectomized subgroup had a higher BrdU-positive cell count in the 90% hepatectomy group, but not in the 70% hepatectomy group (P < 0.001). Splenectomy significantly decreased TGF-beta expression (P = 0.005) and increased the HGF to TGF-beta ratio (P = 0.002) in the 90% hepatectomy group, but not in the 70% hepatectomy group. CONCLUSION: The positive effect of splenectomy on liver regeneration was greater in the group with the larger liver resection. This phenomenon may be related to the relative balance between HGF and TGF-beta in the liver.

Two distinct hantaviruses have been isolated from Apodemus agrarius in 1976 and Rattus norvegicus in 1980 in Korea. Since our serosurveys conducted in 1994, a genetically distinct hantavirus from Apodemus peninsulae has been investigated. To isolate hantavirus from A. peninsulae captured in Korea, the lung homogenate of seropositive A. peninsulae inoculted Vero E6 cells. Viral antigen was detected in a progressively higher percentage of cells with subsequent passage after 80 days postinoculation. The new isolate from seropositive Apodemus peninsulae was designated Suchong virus after Suchong valley located in northeastern region of South Korea. Comparing with hantaan virus 76-118 strain, Suchong virus-1, 2, 3 and 4 showed the similarity of 71.0~91.8% at nucleotide and 90.9~94.8% at amino acid sequences in 231 nucleotides region of M segment, and the similarity of 75.1~81.0% at nucleotide and 97.5~100% at amino acid sequences in 237 nucleotides of S segment.

OBJECTIVE: To evaluate the differences in maxillomandibular transverse measurements at either the crown or the estimated center of resistance (CR), and to compare values between normal occlusion and Class III malocclusion groups. METHODS: Dental casts and computed tomography (CT) data from 30 individuals with normal occlusion and 30 with skeletal Class III malocclusions were evaluated. Using the casts, dental arch widths (DAWs) were measured from the cusp tips, and basal arch widths (BAWs-cast) were measured as the distance between the points at the mucogingival junction adjacent to the respective cusp tips. The BAWs determined from CT (BAWs-CT) images were measured from the estimated CRs of the teeth. RESULTS: None of the DAW measurements or maxillomandibular DAW differences showed statistically significant intergroup differences. In contrast, the maxillary BAWs-CT and BAWs-cast were lesser in the Class III malocclusion group than in the normal occlusion group. The mandibular BAWs-CT were significantly greater in the Class III malocclusion group than in the normal occlusion group. Moreover, the maxillomandibular BAW differences on both CT and cast showed significant intergroup differences in all transverse measurements. CONCLUSIONS: The maxillomandibular DAW differences showed no significant intergroup differences. In contrast, the maxillomandibular BAW differences on both CT and cast showed significant intergroup differences in all transverse measurements. The maxillomandibular BAW differences at the estimated CRs, measured using CT or casts, can reveal underlying transverse maxillary basal arch deficiencies in patients with skeletal Class III malocclusions.

Endoscopic variceal ligation(EVL) was developed to provide a safer alternative than injection sclerotherapy for treatment of bleeding esophageal varices. EVL adds a new indication that will significantly increase the use of overtubes. overtube itself may have a role in predisposing to esophageal perforation but only one report has been published regarding an esophageal perforation related to the placement of an overtube. Recently, we experienced a case of esophageal perforation caused by overtube placement during endoscopic variceal ligation. So we report this case with review of relevant literatures.
