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.

Male chronic pelvic pain syndrome (MCPPS) is defined as chronic pain, pressure, or discomfort localized to the pelvis, perineum, or genitalia of males lasting more than 3 months that is not due to readily explainable causes. Other names for the disorder include prostatodynia and chronic nonbacterial (abacterial) prostatitis, although it is unclear how the symptoms relate to the prostate. And it appears to be extensive variability in clinical presentation and may result in chronic neuropathic pain and neuromuscular pain. Therefore patients with MCPPS should be cared by multimodal treatment including antihyperalgesics, antidepressants and pain intervention procedures such as caudal block. We report successful care in two men with MCPPS.

OBJECTIVE: This study was designed to compare three different measures of the elderly human brain; the magnetization transfer ratio (MTR) histogram, the percentage of brain parenchymal volume, and the volume of T2 hyperintense areas in terms of correlations with the study subjects' neurocognitive performance. MATERIALS AND METHODS: Thirty-five healthy community-dwelling elderly volunteers aged 60-82 years underwent dual fast spin-echo (FSE) imaging and magnetization transfer imaging. A semi-automated technique was used to generate the MTR histogram, the brain parenchymal volume, and the T2 lesion volume. The subjects' neurocognitive performance was assessed by using the Korean-Mini Mental State Examination (K-MMSE) and additional tests. The peak height of the MTR (PHMTR), the percentage of brain parenchymal volume (PBV), and the normalized T2 lesion volume (T2LV) were compared between the normal group (Z score on the K-MMSE > or = -2, n=23) and the mild cognitive impairment group (Z score on the K-MMSE < -2, n=12), and these parameters were correlated with age and various neurocognitive performance scores. RESULTS: The PHMTR was significantly lower in the cognitively impaired subjects than the PHMTR in the normal subjects (p = 0.005). The PBV scores were lower in the cognitively impaired subjects than in the normal subjects (p = 0.02). The T2LV scores were significantly higher in the cognitively impaired subjects (p = 0.01). An inverse correlation was found between the PHMTR and T2LV (r = -0.747, p < ; 0.001), and also between the PBV and T2LV (r = -0.823, p < ; 0.001). A positive correlation was observed between the PHMTR and the PBV (r = 0.846, p < 0.001). Scores on the various neurocognitive tests were positively correlated with the PHMTR (6 of 7 items) and the PBV (5 of 7 items), and they were negatively correlated with the T2LV (5 of 7 items). CONCLUSION: Our findings of a correlation among the PBV, the T2LV, and the PHMTR suggest that MTR histograms and the PBV and T2LV can be used as a reliable method and valid statistical tool, respectively, for quantifying the total lesion burden in an aging brain.

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.
