Nitroblue tetrazolium dye reduction test is now widely used for early detection of bacterial infection. Practically nitroblue tetrazolium dye reduction test (N.B.T. test) gives certain clue to rule out any possibility of aseptic inflammation. Authors performed N.B.T. test for 80 orthopaedic diseases and 40 controls, and the results were as followings: 1. Forty-one of 60 subjects with bacterial infection had more than 10% formazan positive neutrophils, and 18 of 20 subjects without bacterial infection showed less than 10%. formazan positive neutrophils, The groups of the elevated N.B.T. responses were mainly the subjects who had osteomyelitis, soft tissue inflammation, pyogenic arthritis, and bone and joint tuberculosis. 2. The mean proportion of N.B.T. positive neutrophils was 3.8±2.78% in 40 controls, 4.7±4.23% in 20 nonifectious group 12.7±10.3% in 12 chronic osteomyelitis, 12.5±10.7% in 15 treated bone and joint tuberculosis, 20.9±15.65% in 15 untreated bone and joint tuberculosis and 20±10.70% in 11 pyogenic arthritis and 7 other soft inflammatory group. 3. In noninfectious group, 7 of 8 subjects with elevated ESR and 3 of 4 subjects with elevated body temperature revealed N.B.T. responses less than 10%. 4. In 23 subjects with the elevated N.B.T. responses as well as leukecytosis, 22 subjects were the groups of bacterial infection and rest 1 was noninfectious in nature. 5. Therefore, the N.B.T. test is found to be useful for the purposes of the early diagnostic aid of the bacterial infection and differential diagnosis between bacterial infections and other diseases.

Subacute hematogenous ostemyelitis is mostly likely due to an altered relationship between host and pathogen, associated with increase host resistance, decreased virulence of the causative organism and/or antibiotics modification. In a retrospective study of the hematogenous ostemyelitis in 156 cases, 19 cases of them were the subacute form of the ostemyelitis. Pain is the most consistent symptom and most of the constitutional symptoms were usually mild. However, the ESR was often elevated. From our data, the following results were obtained. 1. The most common skeletal involvement was the distal part of the tibia(8 out of 19 patients). 2. The causative organism was staphylococcus aureus by the bacterial culture of the specimens. 3. In the literature, acute hematogenous ostemyelitis rarely cross the physis in patients older than 18 months of its age. However, subacute ostemyelitis frequently does cross the physis(5 out of 19 patients). 4. Cross physeal lesions were healed without any permanant damage to the growth plate in our cases(5 out of 19 patients). 5. All patients except for one case were treated by curettage and antibiotics. 6. The mush higher incidence of the cross physeal lesions may be expected by MRI in identifying the lesion. 7. Seven out of 19 patients had radiographic findings similar to eosinophilic granjuloma, Ewing's sarcoma or osteosarcoma.

BACKGROUND: Healthcare-associated infections (HAIs) are among the most important threats to patient safety. When hospitalized children face these threats, there is morbidity, mortality, prolonged hospitalization, and increased healthcare costs. Research on local healthcare epidemiology is necessary to enhance collective knowledge and evidence formanaging this problem. METHODS: We performed a retrospective analysis of databases of patients who were diagnosed with HAIs at Chung-Ang University Hospital (CAUH) from 2007 through 2011. Cases were selected from the microbiology registry databases. The data on prevalence of HAIs in various wards and its annual trends were compared to previously reported nationwide data. Moreover, we analyzed the patterns of antibiotic susceptibility results for HAI pathogens. RESULTS: A total of 181 HAIs were identified in 122 patients. The HAI rate among pediatric patients at CAUH was 2.4/1,000 person-hospital days. Urinary tract infections (UTIs) (53 episodes, 29.3%) were the most common, followed by pneumonia (33 episodes, 18.2%). Staphylococcus aureus was found to be the most common gram-positive organism, whereas Escherichia coli was the most common gram-negative organism. Methicillin-resistant S. aureus (MRSA) comprised 84% of the S. aureus infections. Imipenem resistance was detected in 58.8% and 55.0% of Acinetobacter baumannii and Pseudomonas aeruginosa isolates, respectively. CONCLUSION: Between 2007 and 2011, UTIs were the most common type of HAIs, and MRSA was the most common pediatric HAI pathogen, both in the general ward and intensive care unit at the CAUH. Further research on the epidemiology and pathogenesis of HAIs is necessary and prevention measures should be implemented to prevent HAIs in children.

There has been so much controversies about the position of upper and lower jaws, and their first permanent molars in normal occlusion and Angle's class I,II,III malocclusions. So, the purpose of this study is to compare the position of upper and lower jaws, and their first molars in normal occlusion and Angle's class IIIIII malocclusions by lateral cephalometric analysis. The sample consisted of one hundred and twenty girls(thirty in each group) who had completed growth. The findings of this study were as follows: 1. In class I malocclusion, both maxilla and mandible were slightly posterior position than normal occlusion, but they showed harmonious relationship. 2. In class II malocclusion, the mandible was greatly retruded, and the maxilla was also slightly retruded to the cranial base as compared with normal occlusion. 3. In class III malocclusion, the maxilla was significantly retruded to the cranial base, but no significant difference was found in mandibular position as compared with normal occlusion. 4. The maxillary first molar was located at posterior position in class II malocclusion, and anterior position in class III malocclusion to the cranium, so that the rotation of mandible was influenced by that. 5. The mandibular first molar showed constant relationship to the mandible in all four groups, but different position to the cranial base in direct proportion to the mandibular position. 6. On the treatment planning of class II malocclusion, it seems to be better to promote the mandibular horizontal growth by inhibiting the vertical growth of maxillary molar area, and on the treatment planning of class III malocclusion, it seems to be better to promote the antero-inferior growth of maxilla and to promote the mandibular vertical growth by inducing the vertical growth of maxillary molar area.

PURPOSE: Wall-eyed bilateral internuclear ophthalmoplegia (WEBINO) is a variation of bilateral internuclear ophthalmoplegia (Bilateral INO) that has profound exotropia in primary position. Head trauma is a rare cause in WEBINO. We report a case of WEBINO after head trauma which was not improved for 9 months and underwent extraocular muscle surgery with adjustable suture. METHODS: A 39-year-old man was referred to the department of ophthalmology for diplopia after head trauma from the department of neurosurgery. He was profoundly exotropic in the primary position and hads bilateral marked limitation of adduction with contralateral abducting nystagmus. There was no improvement even 9 months after the injury, so he underwent extraocular muscle surgery with adjustable suture. RESULTS: At postoperative 6 months, the patient showed orthophoria in the primary position and ocular motility was increased in adduction. There was no diplopia with a large area of binocular single vision in the primary position. CONCLUSIONS: Because of the disruption of normal ocular motor control in WEBINO, the effect of standard muscle surgery is unpredictable. Adjustable surgery is considerable as a useful technique because it is important in making accurate postoperative alignment, especially for diplopia.

C1q nephropathy is a rare glomerular disease, defined by characteristic mesangial C1q immune deposition seen in immunofluorescence microscopy with no serological evidence of systemic lupus erythematosus. C1q nephropathy can be diagnosed with a subsequent biopsy, as with IgA nephropathy. There are some cases with an initial diagnosis of hematuria and proteinuria with minimal disease changes, focal segmental glomerulonephritis, and mesangial proliferative glomerulonephritis, but lacking C1q nephropathy, in which C1q deposition on immunofluorescence subsequently develops. We report a case that was diagnosed as diffuse mesangial proliferative glomerulonephritis, but a subsequent biopsy showed C1q nephropathy, with C1q deposition in both immunohistochemistry and electron microscopy (EM). We treated the C1q nephropathy with methylprednisolone and confirmed the disappearance of C1q depositions by both immunohistochemistry and EM in a follow-up biopsy.
