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.

BACKGROUND: Females generally have a lower pain and temporal summation threshold than men. However, the results of studies designed to evaluate gender differences in the thresholds of heat pain and the temporal summation have been inconsistent. Newly developed device, CHEPS (Contact Heat Evoked Potential Stimulation) model of PATHWAY, have superiority on its fast rise and return time in temperature. Therefore we investigated gender differences in heat pain and temporal summation threshold. METHODS: Forty healthy volunteers (20 males and 20 females) were enrolled in this study. A thermode was applied to the volar side of each volunteer's left forearm and heat pain and the temporal summation threshold was then measured. The heat pain threshold was estimated using the staircase method by starting from 36degrees C and then increasing the temperature in 0.5degrees C increments. The temporal summation threshold was estimated by applying five successive stimulation of the same temperature starting at 2degrees C lower than the heat pain threshold and then increasing the temperature in 0.5degrees C increments. RESULTS: The mean heat pain thresholds was found to be 41.63 +/- 1.63degrees C for males and 41.60 +/- 1.84degrees C for females and the temporal summation thresholds were found to be 40.83 +/- 1.64degrees C for males and 40.77 +/- 1.93degrees C for females. The differences between males and females were not statistically significant. CONCLUSIONS: The result of this study suggested that there are no gender differences in heat pain and temporal summation threshold.

PURPOSE: In this study, we examined the difference in the treatment efficacy depending on the sympathetic activity in men with lower urinary tract symptoms (LUTS). METHODS: In the current single-center, retrospective study, we evaluated a total of 66 male patients aged 40-70 years of age, presenting with LUTS, whose International Prostate Symptom Score (IPSS) exceeded 8 points. They had a past 3-month history of taking alfuzosin XL, and their heart rate variability (HRV) was measured before and after the treatment. In addition, we also recruited 39 healthy volunteers who visited a health promotion center for a regular medical check-up. They were aged between 40 and 70 years and had an IPSS of <8 points. We divided the patients with LUTS into two groups: the groups A and B, based on a low frequency/high frequency (LF/HF) ratio of 1.7, which was the mean value of the LF/HF ratio in the healthy volunteers. After a 3-month treatment with alfuzosin XL, we compared treatment outcomes, based on the IPSS and peak urine flow rate, between the two groups. RESULTS: A 3-month treatment with alfuzosin XL, comprising the measurement of the HRV, was performed for the 23 patients of the group A (23/38) and 17 of the group B (17/28). After a 3-month treatment with alfuzosin XL, total IPSS and IPSS questionnaire 2 and 5 were significantly lower in the group A as compared with the group B. But this was not seen in the group B. Furthermore, there were no significant differences in other parameters, such as maximal flow rate and IPSS storage subscore, between the two groups. CONCLUSIONS: Our results indicate that the treatment efficacy was lower in patients with sympathetic hyperactivity as compared with those with sympathetic hypoactivity. Thus, our results will provide a basis for further studies to clarify causes of LUTS in a clinical setting.

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.
