Association Between Dental Caries Prevalence and Stress Levels in Japanese Children.

Introduction Early life stress (ELS) caused by abuse and bullying has increased dramatically, however, effective means for accurate detection have not been found. Some decades ago, an association between stress and dental caries was suggested. However, even now, stress is not recognized widely as a potential risk factor for caries. Therefore, the purpose of this study was to verify the possible effects of stress by comparing them to the effects of saliva factors and the microorganisms that pose a general caries risk. Methods We conducted cross-sectional observation research on 30 children with mental problems, diagnosed as 'stressed,' and 30 age-matched unstressed children in the same elementary school. An oral examination (dental caries diagnosis) and an oral environment survey (saliva test) were carried out in 2007. Further, the concentration and activity of salivary stress proteins were measured. All variables were statistically analyzed using the Mann-Whitney U test, correlation, and multivariate analysis. Results The dental caries experience ratio was significantly higher in the stress group, and only the concentration of CgA, a salivary stress protein, showed a significant difference. Unexpectedly, we did not detect any differences in the rates and counts of cariogenic bacteria or salivary buffering activity. Binomial logistic regression analysis only showed significance in the presence or absence of ELS. Conclusion Stress factors may have a stronger influence on caries development in the stress group than in the general caries risk. Therefore, long-term stress, causing changes in the children's bodies, might hint at important factors leading to the development of dental caries.

Physical Parameters, Use of Specific Medical Treatments, Nursing Levels, and Activities of Daily Living Are Potential Indicators for Forgoing Maintenance Hemodialysis.

Maintenance hemodialysis (HD) therapy is essential for survival in patients with end-stage renal disease (ESRD); however, HD can also be life-threatening in the final stages of ESRD. Currently, no clear indicators and/or biomarkers exist regarding when HD should be forgone. In the present study, we examined temporal changes in multiple clinical parameters, including biochemical data, physical data, the use of specific medical treatments, nursing care levels, and the activities of daily living (ADL) in 47 ESRD patients who underwent maintenance HD and who died in our hospital. We also investigated the status of informed consents regarding the forgoing of HD in these patients. We found that while biochemical parameters were unaltered, physical parameters such as consciousness levels and blood pressure gradually deteriorated during hospitalization. The use of the following specific medical treatments significantly increased over time: vasopressor use, O2 inhalation, and ventilator use. The need for nursing care increased and the ADL levels decreased toward the time of death. Medical doctors gave information regarding forgoing HD to patients and/or their family/relatives in 55% of cases, obtained agreement to forego HD in 45% of cases, and HD was actually foregone in 38% of cases. Most clinical parameters were not significantly different between the patients whose HD sessions were forgone versus those in whom HD was continued, indicating that HD was foregone in the very last stages of life. The results suggest that physical parameters, the use of specific medical treatments, the levels of nursing care, and ADL are potential indicators for forgoing HD in the final stages of ESRD.

Follow-up study of female delinquent adolescents in a detention centre: effectiveness of psychiatric intervention as a mental health service.

RESULTS: of previous studies suggest that many female offenders have co-morbid psychiatric disorders, which require mental health services. However, few longitudinal studies examined subjects during incarceration or detention. This study compares depressive symptoms, abnormal eating behaviour and impulsivity before release from a detention centre and after incarceration, thereby indicating the effectiveness of psychiatric intervention in a Japanese detention centre. METHOD: Of 64 young women, 36 were followed up. Self-report measures were used to assess depression, eating behaviour and impulsivity after incarceration and one month before release. RESULT: s: Of the 36 participants, nine were diagnosed using the MINI-kids as needing mental health services. Those who received psychiatric intervention were diagnosed as having major depression and/or post-traumatic stress disorder. Significant main effects of intervention and effects of time were shown in the DSD. The EAT-26 score demonstrated the significance of the effects of time and interaction. In the BIS-11 scores, neither intervention nor time showed significant effects. CONCLUSIONS: Results of this study showed that the time course and psychiatric intervention contributed to recovery of depression and therapeutic intervention. The time course might reduce eating problems. Psychiatric intervention might be necessary for female juvenile detainees, which presents an important issue for future studies.

A comparison of the handling and accuracy of syringe and vial versus prefilled insulin pen (FlexPen).

BACKGROUND: To determine the preferable method for self-injecting insulin, we compared the handling, safety, and dose accuracy of a conventional disposable syringe and vial with FlexPen (Novo Nordisk A/S, Bagsvaerd, Denmark), a prefilled pen. METHODS: Insulin therapy-naive healthcare professionals (HCPs) (n = 30), unfamiliar with insulin delivery, injected 10 U of insulin into a sponge pad using either a syringe and vial or the FlexPen, both with 30-gauge 8-mm needles, on day 1. The following day, they used the alternative method. They evaluated the handling of the two methods on device-specific questionnaires and compared overall preference on a third questionnaire. To evaluate dose accuracy, 30 insulin therapy-experienced HCPs and 20 insulin therapy-naive HCPs were asked to deliver 10 U of insulin using each method, and the amount discharged was weighed. RESULTS: FlexPen was rated easier to use and overall more preferable than the syringe and vial by insulin therapy-naive HCPs (P < 0.001). The pen device was more accurate than the syringe and vial when used by experienced HCPs (mean +/- SD dose delivered, 9.91 +/- 0.11 U vs. 9.82 +/- 0.25 U, respectively; P < 0.001) and by insulin therapy-naive HCPs (9.91 +/- 0.12 U vs. 9.74 +/- 0.85 U; P < 0.001). CONCLUSIONS: Insulin therapy-naive HCPs found FlexPen easier to handle and preferable to use compared to a conventional syringe and vial. Both insulin therapy-experienced and -naive HCPs were able to deliver insulin significantly more accurately with the FlexPen than with a syringe and vial (P < 0.001).

Trauma exposure and posttraumatic stress disorder in delinquent female adolescents.

BACKGROUND: Although juveniles within the justice system have high psychiatric morbidity, few comprehensive investigations have shown posttraumatic stress disorder (PTSD) in female delinquents. Here, we aim to describe the nature and extent of PTSD and trauma exposure and to clarify the relationships among comorbidity and psychosocial factors in juvenile female offenders. METHOD: Sixty-four girls were randomly interviewed using structured tools. Self-report measures were used to assess depression, eating behaviour, impulsivity and parental attitude. RESULTS: The PTSD prevalence was 33%, and 77% of the female juvenile offenders had been exposed to trauma. The offenders with PTSD showed a significantly high psychiatric comorbidity. Depression and adverse parenting were associated with PTSD development, and abnormal eating was also correlated with PTSD symptoms. Marked differences in the frequency and intensity of PTSD evaluation depending on the type of comorbidity and trauma were observed. CONCLUSIONS: Incarcerated young females in Japan have serious trauma-related problems, and the degree of depression is a strong predictor of PTSD development and symptoms. This study highlights the importance of adequate diagnosis and treatment of PTSD in delinquent female adolescents.

Usability of a microtapered needle (TN3305) for insulin treatment in japanese patients with diabetes mellitus: a comparative clinical study with a standard thin wall needle.

BACKGROUND: We evaluated the clinical usability of a microtapered needle (TN3305, "Needle T," Terumo Corp., Tokyo, Japan) by comparing it with a standard needle (Micro-Fine +, 31 gauge, 5 mm, thin wall, "Needle B," Nippon Becton Dickinson Co., Ltd., Tokyo) in a multicenter study. METHODS: Ninety-nine patients with diabetes mellitus being treated in 11 Japanese hospitals were enrolled in the study. Written consent was obtained from all patients. They were allocated randomly to two groups by an envelope (crossover) method. Injections were performed using one needle first, followed by the other needle 4 or 5 days later. Pain caused by injection was evaluated using a visual analogue scale (VAS). RESULTS: In the overall evaluation, Needle T was chosen by 40 patients (44.4%) and Needle B by 17 (18.8%); 33 patients (36.7%) expressed no preference. VAS scores for Needles T and B were 1.48 +/- 0.18 and 2.47 +/- 0.24 cm, respectively (P < 0.001). In this study, lower VAS indicated less pain. CONCLUSIONS: The preferences and VAS scores suggested that Needle T caused less pain than Needle B. The incidence of adverse events and safety were equivalent for both needles. We believe that usability of Needle T by patients for self-injection is better.
