The noise is defined as unwanted sound that causes discomfort and physical changes. This study was conducted to evaluate intensity of noise in the pediatric dental clinic and to investigate noise environment of a pediatric dentist. Human ear shaped microphone and mobile noise level meter were used for recording noise and calculating intensity of noise.
By recording according to the method specified by Korea Occupational Safety and Health Agency (KOSHA) of Korea Ministry of labor and employment, the following results were obtained. For 16 experimental days, 8 hour time weighted average (8hr-TWA) was 49.33 dBA (A-weighted deci-Bell) on daily average with maximum 58.54 dBA and minimum 33.97 dBA. And Dose was 0.49% on daily average with maximum 1.28%, minimum 0.04%. These values are less than criteria of KOSHA standard (85 dBA, 100%). Comparing the highest noise level for each patient, pulp therapy group and Frankel grade I group were the highest.
The intensity of dental noise of pediatric dental clinic didn’t meet standard of KOSHA. It is necessary to re-evaluate noise environment by establishing new standards considering environment of pediatric dental clinic.

BACKGROUND: The purpose of this stady is to define the clinical characteristics of Tsutsugamushi disease. METHODS: We analyzed 12 cases of tsutsugamushi disease admitted to BAG AE general hospital from 1999. Oct. 1st to Dec. 10. Tsutsugamushi disease was diagnosed by indirect immunofluorescent antibody test. RESULTS: 1) Among them, 8 cases were female and 4 cases were male. The prevalence was predominantly high in female. 2) The age distribution ranged from 40 to 80 years old. The high incidence of age was 70's and 80's. 3) The peak incidene was showed between October and November.(91.6%). 4) The most frequent symptoms were fever and chills(91.6%). 5) Rash and eschar were observed in 83.3%(10 of 12) both. 6) Hepatosplenomegaly and lymphadenopathy were also observed in 25%(3 of 12), 16.6%(2 of 12) respectively. 7) The Laboratory finding showed the elevation of AST 66.6% (8 of 12), ALT 58.3%(7 of 12), alkaline phosphatase 25%(3 of 12) and LDH 25%(3 of 12). Albuminuria and hypoalbuminuria were also observed in 25%(3 of 12), 58.3%(7 of 12) respectively. 8) The therapeutic efficacy of doxycycline was excellent. CONCLUSION: Tsutsugamushi disease which appeared in Pyoungtack area showed typical clinical pattern and was effective to doxycycline treatment.

Black staining of the teeth in children and adolescents does not cause pain or serious illness, but it can be socially debilitating for esthetic reasons. Black staining is easily removed through periodic professional mechanical tooth cleaning and ultrasonic scaling, but it can easily recur within few months. Using essential oil-containing mouth rinses diluted at 50% twice per day could prevent the black staining from returning after it is removed, reducing the need for mechanical treatments and improving esthetics.

Lumbar intraspinal synovial cysts are included in the difference diagnosis of lumbar radiculopathy. Developing imaging modalities has result in increased reporting about these lesions. However, the case of bilateral new lumbar intraspinal synovial cysts after laminectomy has been rarely reported. We report of a rare case with bilateral lumbar intraspinal synovial cysts after laminectomy, requiring surgical excision.

Although postherpetic neuralgia (PHN) is a common chronic pain syndrome, the pathophysiology of this disorder is not well known and management is often very difficult. N-Methyl-D-Aspartate (NMDA) receptor antagonists are known to be effective in PHN, and magnesium, a physiological blocker of NMDA receptors, is widely used to treat various chronic pain disorders. Here, we present a case of the PHN refractory to conventional treatment, which was treated successfully with transforaminal epidural injection of magnesium sulphate at the affected dermatome.

The success of dental implant therapy relies mainly upon the presence and maintenance of bone adjacent to implant. An 1-year prospective study was performed, upon the patients who were diagnosed as having chronic adult periodontitis, and had been treated with dental implant. The purpose of this study was to measure the radiographic bone level changes proximal to Astra Tech Single Tooth Implants (ATST, Astra Tech AB, MOlndal, Sweden) with microthread and Astra Tech TiOblast Implant (ATTB) without microthread supporting fixed partial prosthesis. Measurements were used to determine mean marginal bone loss during the first year of loading. 17 subjects with its partial prosthesis supported by 37 implants were followed up for an 1-year period. The marginal bone loss of implants was positively correlated with the retention factor, microthread (Microthread(TM)) in crestal area of ATST. The results were as follows. 1. The mean marginal bone loss of ATST was 0.226+/-0.395mm, while ATTB was 0.440+/-0.360mm. There was a statistically significant difference between ATST and ATTB (p<0.05). 2. The mean bone loss of the upper jaw fixtures was 0.269+/-0.265mm for ATST and 0.529+/-0.417mm for ATTB. There was a statistically significant difference between ATST and ATTB (p<0.05). In the lower jaw the corresponding figures were 0.167+/-0.231mm and 0.313+/-0.214mm, respectively. There was no significant difference between ATST and ATTB (p>0.05). 3. The mean bone loss of ATST was lower than that of ATTB at all sites according to bone quality. There was a statistically significant difference between ATST and ATTB at bone quality type III (p<0.05). In conclusion, the mean bone loss of ATST was smaller than that of ATTB. Therefore, the retention factor of crestal area, microthread (Microthread(TM)) was effective to maintenance of marginal bone level around fixture.

BACKGROUND: Determination of antibody specificity using antigram spread sheet requires experience and knowledge on in vitro characteristics of red cell antibodies, time-consuming, and still subjective to human error. A computer-based antibody identification system was developed to overcome these disadvantages. METHODS: Decision support system program for antibody identification was designed using Visual Basic 5.0 for Dade Data-cyte Plus. This system integrates the reaction patterns of saline, 37degrees C albumin, antiglobulin, 4degrees C saline enzyme treated and user-defined phases and lists the antibodies according to the probability. 115 irregular antibodies previously confirmed by standard manual method reanalyzed with this program. RESULTS: In 111 of 115 cases (96.5%), this system produced the same results with the manual identification. In two cases, of not matched 4 cases the computer program suggested additional antibodies and in one case, the computer program detected previous human error. In the other case, antibody identification was possible only after further tests including selective adsorption of multiple antibodies. CONCLUSION: The decision support system was rapid and easy and showed good concordance rate when compared with manual antibody identificaion results. In addition, human error could be reduced. Decision support system for antibody identification could be used in small blood banks by less experienced staffs.
