Crown removal and endodontic drainage as a last method in active gingival bleeding with liver cirrhosis and periodontitis: a case report

The most common local cause of active gingival bleeding is the vessel engorgement and erosion by severe inflammation. Abnormal gingival bleeding is also associated with the systemic disturbances. Hemorrhagic disorders in which abnormal gingival bleeding is encountered include the following: vascular abnormalities (vitamin C deficiency or allergy), platelet disorders, hypoprothrombinemia (vitamin K deficiency resulting from liver disease), and other coagulation defects (hemophilia, leukemia). There are many conventional methods for gingival bleeding control, such as, direct pressure, electrocoagulation, direct suture, drainage, application of hemostatic agents and crushing and packing. If the active continuous gingival bleeding is not stopped in spite of the application of all conventional bleeding control methods, the life of patient is threatened owing to upper airway obstruction, syncope, vomiting and hypovolemic shock. Therefore, the rapid and correct hemostatic method is very important in the emergency dental care.

USE OF A COMPUTER NAVIGATION SYSTEM FOR OSTEOTOMIES IN THE ORTHOGNATHIC SURGERY: TECHNICAL NOTE

Antibiotic prophylaxis in the operation of the closed mandibular fractures and the efficacy of postoperative antibiotics

PURPOSE: This study compared the frequency of postoperative infections in patients for a closed mandibular fracture with that without the ostoperative antibiotic prophylaxis. Patients and Methods: 48 patients without any specific medical history were divided into two groups depending on whether or not antibiotics had been applied after the surgery. The 24 patients in group 1 received only a second-generation cephalosporin (Cefotetan(R)) ntravenously from admission to immediate after the surgery. Likewise, 24 patients in group 2 received 1.0g of Cefotetan(R) twice daily longer than the third day after surgery. The mean (SD) duration of antibiotics administration after surgery was 6.9 (+/-3.56). The patients were evaluated after surgery for any postoperative infections according to the criteria: purulent drainage from a wound, spontaneous wound dehiscence accompanied by swelling, pain, and fever around the wound. RESULTS: Postoperative infections were encountered in 2 out of 24 patients in group 1, who received antibiotic medication until shortly after surgery, and in 3 out of the 24 patients in group 2, in whom the medication was continued even after the surgery. There was no sig nificant difference in the incidence of postoperative infections between the two groups. CONCLUSION: From this study, postoperative use of antibiotics seems to be unnecessary with view of the little significance of the factors that could affect the wound infection.

Study of User Preference of Graphic User Interface in Laboratory Information System / 대한의료정보학회지

In order to elucidate employees satisfaction levels in using graphic user interface(GUI) in a laboratory information system(LIS), users attitudes toward GUI versus CUI(Character User Interface) in a similar LIS were surveyed one month after implementing upgrade version of LIS in a tertiary care university hospital laboratory. The outcome of the study showed that approximately two third of users preferred to have GUI in LIS. There was no difference in preference of GUI or not. However the female and older employees tend to shy away from GUI. The employee productivity was improved with GUI although it takes slightly longer program loading time than that of CUI. In conclusion, the laboratory employee satisfaction was higher with GUI than CUI and their productivity was improved with GUI.
