Rapidly progressive fatal idiopathic hypertrophic pachymeningitis with brainstem involvement in a child.

BACKGROUND: Hypertrophic pachymeningitis (HP) is a rare disorder characterized by diffuse thickening of the dura mater with resultant neurologic deficits. HP develops secondary to various conditions or idiopathically usually in adults but rarely in children. CASE REPORT: We describe a 3-year-old female child with idiopathic HP. Her HP involved the entire central nervous system with progression into the brainstem. The lesion responded poorly to pulsed steroids or any immunosuppressants. The brainstem lesion grew rapidly and formed various nodules that ultimately resulted in brain death. This is the first fatal case of HP in a child.

Changes in mental health and quality of life with dental implants as evaluated by General Health Questionnaire (GHQ) and Health Utilities Index (HUI).

OBJECTIVES: The purpose of this study was to assess and compare the improvement in oral and systemic conditions and health-related quality of life in patients with missing teeth receiving dental implants and conventional treatment. METHODS: A total of 97 patients with missing teeth, of whom 59 received dental implants and 38 received conventional treatment, were included in this study. The patients were divided into two age groups for a more detailed analysis: a 30- to 59-year age group (young) and a >60-year age group. The changes in oral condition, mental health, and health utility level before and after (pre- and post-, respectively) the procedures were assessed using an original questionnaire, the General Health Questionnaire 12 (GHQ12), and Health Utilities Index Mark 3. RESULTS: Responses to the GHQ12 indicated that treatment with implants significantly improved the oral health of patients in all treatment groups, except for the young group receiving partial dentures (PD). The mental state improved with a lower GHQ score; in terms of pre- versus post-procedure, mental state improved after the procedure in the young group receiving full dentures (FD) (1.75 ± 2.12 vs. 0.88 ± 2.10, p < 0.05), in the old group receiving PD (2.61 ± 3.91 vs. 0.72 ± 1.71, p < 0.05), and in the old group receiving FD (2.63 ± 3.12 vs. 0.44 ± 0.27, p < 0.05). The sleep score also improved by implant in FD of the old group (2.00 vs. 1.00, p < 0.05); it also is better with a lower score. CONCLUSIONS: Recovery of oral function and oral stability in middle-aged people who did not receive implants was possible with PD. However, the results suggest that implant treatment in edentulous denture cases and particularly in elderly people with dentures has a certain efficacy on the physical condition mediated through an improvement in aspects of the mental state.

An occupational health study of emergency physicians in Japan: health assessment by immune variables (CD4, CD8, CD56, and NK cell activity) at the beginning of work.

This study was conducted to evaluate the occupational health of Japanese physicians in emergency medicine. Subjects participating in this study were eighty-nine physicians working at 12 medical facilities (10 critical care emergency centers) in Japan. Participants were asked to complete a questionnaire of work conditions and to provide blood samples for immune variable measurements (CD4, CD8, CD56 and natural killer cell (NK cell) activity) before commencing their work. The data collected from seventy-four of 89 participating physicians were analyzed. The traditional work group comprised of 39 emergency physicians, who were significantly overworked compared to other two groups: the shift work group and the day work group. Among these three groups, no immune variable was significantly different except lymphocyte, number of CD4, and NK cell activity; and the NK cell activity of the shift work group was significantly lower than those of the traditional work group (p<0.01) and the day work group (p<0.01) in terms of Bonferroni's multiple comparison, probably due to circadian rhythm. It was indicated that NK cell activity was significantly lower in samples collected at night versus in the morning (OR=8.34, 95%CI: 1.95-35.6, p<0.01) through multiple logistic regression analyses. NK cell activity was significantly lower in individuals taking 0-3 days off per month, as compared to those taking 4 or more days off (OR=4.65, 95%CI: 1.27-17.0, p=0.02), according to multiple logistic regression analyses. Therefore, the low NK cell activity appears to have reflected the extent of fatigue arising from physicians' overwork. Overwork would have been a potential risk for the physicians' health, resulting in a lower quality of Japanese emergency medical services than that which could have been achieved otherwise. This study suggests that it would be better for the Japanese emergency physicians to take 4 or more days off per month for their health and the quality of their services.

The relationship between long-term changes in plasma B-type natriuretic peptide levels and electrocardiographic findings.

OBJECTIVES: Changes in B-type natriuretic peptide (BNP) and electrocardiographic (ECG) findings in an adult Japanese population were measured over a 5-year period, and the statistical relationships between these were evaluated. METHODS: This was a longitudinal analysis in which data were collected on 353 subjects (135 men and 218 women) who had undergone general health checks in 1998 and 2003. RESULTS: Data were examined by correlation coefficient and one-way analysis of covariance using repeated measurements. The correlation coefficient for BNP between 1998 and 2003 was 0.622 (P < 0.0001) for the men and 0.557 (P < 0.0001) for women. The changes in BNP over the same period were 13.71 +/- 26.06 (P < 0.0001) pg/ml in the men and 20.17 +/- 32.01 (P < 0.0001) pg/ml in the women. In 99 men and 145 women who had undergone ECG tests, with both normal and abnormal findings, visual inspections of changes in the ECG findings with respect to BNP changes were performed over the 5-year period. In men, both age and BNP significantly correlated with changes in ECG findings; however, in women, no significant correlation between BNP and changes in ECG findings was observed. CONCLUSIONS: This regional longitudinal study revealed a gender difference in the relationship between long-term changes in BNP and ECG findings, suggesting that a 10 pg/ml or more increase in BNP in men over a 5-year period may a indicate worsening of cardiac function and the need for intervention.
