Staphylococcal cassette chromosome mec (SCCmec) type and coagulase serotype are important epidemiologic factors in methicillin-resistant Staphylococcus aureus (MRSA). To investigate correlation between SCCmec type and coagulase serotype of MRSA, we analyzed SCCmec types of MRSA strains isolated from clinical sources and compared the results to coagulase serotypes and antimicrobial susceptibility patterns. A total of 108 MRSA isolates were classified into four SCCmec types: II (55.6%), IV (21.3%) III (13.0%) and IIIA (8.3%), and five coagulase serotypes: II (54.6%), IV (21.3%), V (18.5%) and VII (2.8%). All of coagulase type II, IV and V strains belonged to SCCmec type II, III/IIIA and IV, respectively. SCCmec types II, III and IIIA were multidrug resistant, whereas SCCmec type IV strains were non-multidrug resistant except beta-lactams and erythromycin. The data provide that there is a significant correlation between SCCmec types and phenotypic characteristic of coagulase serotypes.

We present a case of hyaline vascular type Castleman disease involving the bilateral cervical lymph nodes. To our knowledge, no previous case of this localized form of the disease has been reported. Dynamic CT demonstrated a hypervascular pattern of enhancement, with central less enhanced areas that corresponded histologically to fibrosis. For the diagnosis of this uncommon lymph node disease, these findings might be helpful.

The purpose of this study was to investigate the effects of the Co-60 gamma irradiation on the osseointegration. 2.0 mm titanium alloy screw implants were placed in the tibial metaphysis of the rabbits, bilaterally. The mean length of the implants was 6.0 mm. The right tibia was irradiated with a single dose of 15 Gy from 60Co teletherapic machine at 5th postoperative day. The experimental group was irradiated tibia. The control group was non-irradiated tibia. To observe the phase of bone formation, the bone labeling by intramuscular injection of 20mg/Kg of Tetracycline, Calcein, Alizarin red S, was performed. The rabbits were sacrificed on the 1st, 2nd, 4th, 6th, 8th week and the tibia including implants were taken, and then the specimens were examined by the microradiography, light microscopy, and fluorescent microscopy. The obtained results were as follows; 1. There were connective tissue between bone and titanium at 1st week, in both group. Especially, the many empty lacunae without nucleus and obscure cytoplasm in experimental group, were observed. 2. The osteons were observed at 4th week in control group, and at 6th week in experimental group. The bone formation in experimental group was retarded as compared to the control group. 3. In fluorescent microscopy, bone labelling band was observed as linear, arc or concentric shape. Occasionary interrupted labelling band was observed, which is demonstrated bone remodeling. 4. In microradiographic examination, the radiolucent image was found between bone and implant with widening of bone marrow spaces as compared to the control group.

Aspiration can generate postoperative pulmonary morbidity of varing severity, depending on the type and volume of the aspirate. Epidural anesthesia can lead to local anesthetic systemic toxicity with mental change, followed by respiratory depression and abdominal and intercostal muscle weakness depressing the ability of the patient to cough and clear the airway. The authors experienced a case of pulmonary aspiration with systemic toxicity after epidural anesthesia for cesarean section. The chest X-ray showed alveolar consolidation at left lower lung field and arterial blood gases showed that PaO2 decreased. The exact causes of mental change and respiratory depression were unknown, but we suspected it lidocaine induced systemic toxicity due to vascular absorption, When airway reflexes are ineffective during face mask ventilation of the lungs, aspiration of clear oral secretions can generate small airway obstruction.

It is generally believed that the anomalous pancreaticobiliary duct union (APBDU) might be involved in the formation of choledochal cyst and malignancies of hepatopancreaticobiliary system. The purpose of this study is to make an animal model of APBDU similar to that of human. One to two-month-old Mongrel dogs (n=12) were divided into two groups; the control group (n=2) in which sham operation was performed, and the experimental group (n=10) in which the end of distal common bile duct (CBD) was anastomosed to the side of dorsal pancreatic duct to produce APBDU. Serum was obtained for chemical analysis at the 10th postoperative day. The dogs were sacrificed at the 5th week (n=3), the 6th week (n=3), the 7th week (n=2), the 8th week (n=2) and the 6th month (n=2) after the operative intervention. At the day when the experimental animals were sacrificed, operative cholangiogram was taken, and bile juice was obtained for chemical analysis and bacterial culture. The en-bloc specimens of hepatopancreaticobiliary system were obtained for microscopic examination. Serum and bile juice amylase levels were elevated in the experimental group (n=10), but not in the control group (n=2). On operative cholangiogram, there was no evidence of bile duct dilatation in control group (n=2). On the other hand, bile duct in the experimental group was markedly dilated without any evidence of stenosis in all (n=10). Histologic examination of the hepatopancreaticobiliary system in the experimental group resembled the findings of choledochal cyst in human. The APBDU of this animal model can produce bile duct dilatation by pancreaticobiliary reflux. We think that this animal model can be potentially promising for the research about the APBDU associated hepatopancreaticobiliary diseases.

PURPOSE: To assess the diagnostic accuracy and value in an imaging technique field through the comparison of cone beam computed tomography and conventional panoramic radiography in assessing the topographic relationship between the mandibular canal and impacted third molars. MATERIALS AND METHODS: Participants consisted of 100 patients offered the images through cone beam computed tomography and panoramic radiography. PSR-9000(TM) Dental CT system (Asahi Roentgen Ind. Co., Ltd, Japan) was used as the unit of cone beam computed tomography. CE-II (Asahi Roentgen Ind. Co., Ltd, Japan) and Pro Max (Planmeca Oy, Finland) were used as the unit of panoramic radiography. The images obtained through panoramic radiography were classified into 3 types according to the distance between mandibular canal and root of mandibular third molar. And they were classified into 4 types according to the proximity of radiographic feature. The images obtained through cone beam computed tomography based on the classification above were classified into 4 types according to the location between the mandibular canal and the root and were analyzed. And they were classified into buccal, inferior, lingual, and between roots, according to the location between mandibular canal and root. The data were statistically analyzed and estimated by chi-square-test. RESULTS: 1. There was no statistical significance according to 3 types (type l, type ll, type lll) through CBCT. 2. The results of 4 types (type A, type B, type C, type D) through CBCT were as high prevalence of CBCT 1 in type A, CBCT 2 in type B, CBCT 3 in type C, and CBCT1 in type D and those of which showed statistical significance (P value=0.03). 3. The results according to location between mandibular canal and root through CBCT recorded each 49, 25, 17, 9 as buccal, inferior, lingual, between roots. CONCLUSION: When estimating the mandibular canal and the roots through the panoramic radiography, it could be difficult to drive the views of which this estimation was considerable. Thus it is required to have an accurate diagnostic approaching through CBCT that could estimate the location between mandibular canal and roots.
