Temporomandibular disorders/myoarthropathy of the masticatory system. Costs of dental treatment and reimbursement by Swiss federal insurance agencies according to the Health Care Benefits Ordinance (KLV)

The goal of the study was to calculate the direct costs of therapy for patients with MAP. This retrospective study included 242 MAP patients treated at the Department of Prosthodontics of the University of Bern between 2003 and 2006. The following parameters were collected from the clinical charts: chief complaint, diagnosis, treatment modalities, total costs, costs of the dental technician, number of appointments, average cost per appointment, length of treatment, and services reimbursed by health insurance agencies. The average age of the patients was 40.4 ± 17.3 years (76.4% women, 23.6% men). The chief complaint was pain in 91.3% of the cases, TMJ noises (61.2%) or limitation of mandibular mobility (53.3%). Tendomyopathy (22.3%), disc displacement (22.4%), or a combination of the two (37.6%) were more often diagnosed than arthropathy alone (7.4%). Furthermore, 10.3% of the MAP patients had another primary diagnosis (tumor, trauma, etc.). Patients were treated with counseling and exercises (36.0%), physiotherapy (23.6%), or occlusal splints (32.6%). The cost of treatment reached 644 Swiss francs for four appointments spread over an average of 21 weeks. In the great majority of cases, patients can be treated with inexpensive modalities. 99.9% of the MAP cases submitted to the insurance agencies were reimbursed by them, in accordance with Article 17d1-3 of the Swiss Health Care Benefits Ordinance (KLV) and Article 25 of the Federal Health Insurance Act (KVG). The costs of treatment performed by dentists remain modest. The more time-consuming services, such as providing information, counseling and instructions, are poorly remunerated. This aspect should be re-evaluated in a future revision of the tariff schedule.

Assessing Nursing Assistants' Knowledge of Behavioral Approaches to Mental Health Problems

Nurse's aides are the primary caregivers in nursing homes, a major receiving site for elders with behavioral and psychiatric problems. We describe the development, psychometric properties, and utility of a brief instrument designed to assess aides' knowledge of three specific mental health problems (depression, agitation, and disorientation) and behavioral approaches to them. The instrument was administered to 191 nurse's aides and 21 clinicians with training in behavioral management and experience with older residents. The nurse's aides averaged 11 of 17 correct answers, and the clinicians averaged 15 of 17 correct answers. Implications for staff training and consultation activities in nursing homes are discussed.

Transmembrane tumor necrosis factor alpha is required for enteropathy and is sufficient to promote parasite expulsion in gastrointestinal helminth infection

To study the specific role of transmembrane tumor necrosis factor (tmTNF) in protective and pathological responses against the gastrointestinal helminth Trichinella spiralis, we compared the immune responses of TNF-alpha/lymphotoxin alpha (LTalpha)(-/-) mice expressing noncleavable transgenic tmTNF to those of TNF-alpha/LTalpha(-/-) and wild-type mice. The susceptibility of TNF-alpha/LTalpha(-/-) mice to T. spiralis infection was associated with impaired induction of a protective Th2 response and the lack of mucosal mastocytosis. Although tmTNF-expressing transgenic (tmTNF-tg) mice also had a reduced Th2 response, the mast cell response was greater than that observed in TNF-alpha/LTalpha(-/-) mice and was sufficient to induce the expulsion of the parasite. T. spiralis infection of tmTNF-tg mice resulted in significant intestinal pathology characterized by villus atrophy and crypt hyperplasia comparable to that induced following the infection of wild-type mice, while pathology in TNF-alpha/LTalpha(-/-) mice was significantly reduced. Our data thus indicate a role for tmTNF in host defense against gastrointestinal helminths and in the accompanying enteropathy. Furthermore, they also demonstrate that TNF-alpha is required for the induction of Th2 immune responses related to infection with gastrointestinal helminth parasites.

Health literacy among young adults: a short survey tool for public health and health promotion research

Health literacy (HL) is context-specific. In public health and health promotion, HL in the private realm refers to individuals' knowledge and skills to prevent disease and to promote health in everyday life. However, there is a scarcity of measurement tools explicitly geared to private realm contexts. Our aim was to develop and test a short survey tool that captures different dimensions of HL in the context of family and friends. We used cross-sectional data from the Swiss Federal Surveys of Adolescents from 2010 to 2011, comprising 7983 males and 366 females between 18 and 25 years. HL was assessed through a set of eight items (self-reports). We used principal component analysis to explore the underlying factor structure among these items in the male sample and confirmatory factor analysis to verify the factor structure in the female sample. The results showed that the tested item set represented dimensions of functional, interactive and critical HL. Two sub-dimensions, understanding versus finding health-relevant information, denoted functional HL. Interactive and critical HL were each represented with two items. A sum score based on all eight items (Cronbach's α: 0.64) showed expected positive associations with own and parental education among males and females (p < 0.05). The short item set appears to be a feasible measurement tool to assess HL in the private realm. Its broader application in survey studies may help to improve our understanding of how this form of HL is distributed in the general population.

Developing Dramatic Movies to Teach Interdisciplinary Collaboration to Allied Health, Medical and Nursing Students

Many times a Hollywood movie has scenes that are useful to illustrate aspects of health care practice. However, it is often impractical to use an entire two-hour movie in class, and a clip or two really does not convey the dramatic picture that the complete movie reveals.

Caries-preventive effectiveness of fluoride varnish as adjunct to oral health promotion and supervised tooth brushing in preschool children: a double-blind randomized controlled trial.

OBJECTIVES To evaluate the effect of biannual fluoride varnish applications in preschool children as an adjunct to school-based oral health promotion and supervised tooth brushing with 1000ppm fluoride toothpaste. METHODS 424 preschool children, 2-5 year of age, from 10 different pre schools in Athens were invited to this double-blind randomized controlled trial and 328 children completed the 2-year programme. All children received oral health education with hygiene instructions twice yearly and attended supervised tooth brushing once daily. The test group was treated with fluoride varnish (0.9% diflurosilane) biannually while the control group had placebo applications. The primary endpoints were caries prevalence and increment; secondary outcomes were gingival health, mutans streptococci growth and salivary buffer capacity. RESULTS The groups were balanced at baseline and no significant differences in caries prevalence or increment were displayed between the groups after 1 and 2 years, respectively. There was a reduced number of new pre-cavitated enamel lesions during the second year of the study (p=0.05) but the decrease was not statistically significant. The secondary endpoints were unaffected by the varnish treatments. CONCLUSIONS Under the present conditions, biannual fluoride varnish applications in preschool children did not show significant caries-preventive benefits when provided as an adjunct to school-based supervised tooth brushing with 1000ppm fluoride toothpaste. CLINICAL SIGNIFICANCE In community based, caries prevention programmes, for high caries risk preschool children, a fluoride varnish may add little to caries prevention, when 1000ppm fluoride toothpaste is used daily.

VEGFR2 Signaling Prevents Colorectal Cancer Cell Senescence to Promote Tumorigenesis in Mice With Colitis.

BACKGROUND & AIMS Senescence prevents cellular transformation. We investigated whether vascular endothelial growth factor (VEGF) signaling via its receptor, VEGFR2, regulates senescence and proliferation of tumor cells in mice with colitis-associated cancer (CAC). METHODS CAC was induced in VEGFR2(ΔIEC) mice, which do not express VEGFR2 in the intestinal epithelium, and VEGFR2(fl/fl) mice (controls) by administration of azoxymethane followed by dextran sodium sulfate. Tumor development and inflammation were determined by endoscopy. Colorectal tissues were collected for immunoblot, immunohistochemical, and quantitative polymerase chain reaction analyses. Findings from mouse tissues were confirmed in human HCT116 colorectal cancer cells. We analyzed colorectal tumor samples from patients before and after treatment with bevacizumab. RESULTS After colitis induction, VEGFR2(ΔIEC) mice developed significantly fewer tumors than control mice. A greater number of intestinal tumor cells from VEGFR2(ΔIEC) mice were in senescence than tumor cells from control mice. We found VEGFR2 to activate phosphatidylinositol-4,5-bisphosphate-3-kinase and AKT, resulting in inactivation of p21 in HCT116 cells. Inhibitors of VEGFR2 and AKT induced senescence in HCT116 cells. Tumor cell senescence promoted an anti-tumor immune response by CD8(+) T cells in mice. Patients whose tumor samples showed an increase in the proportion of senescent cells after treatment with bevacizumab had longer progression-free survival than patients in which the proportion of senescent tumor cells did not change before and after treatment. CONCLUSIONS Inhibition of VEGFR2 signaling leads to senescence of human and mouse colorectal cancer cells. VEGFR2 interacts with phosphatidylinositol-4,5-bisphosphate-3-kinase and AKT to inactivate p21. Colorectal tumor senescence and p21 level correlate with patient survival during treatment with bevacizumab.

Threat of alveolar echinococcosis to public health - a challenge for Europe

Alveolar echinococcosis (AE) is a neglected 'malignant' parasitic disease. The European endemic area of Echinococcus multilocularis in foxes is larger than previously anticipated, and there is new evidence that both fox populations and the prevalence of E. multilocularis have increased in many areas, indicating increased pressure for infection with E. multilocularis eggs in intermediate and accidental hosts, including humans. This may result in more human AE cases within the next decades. Current numbers of both immunocompetent and immunocompromised AE patients, and the anticipated future increase, call for scaling-up research to rapidly improve the development and implementation of prevention measures, early diagnosis, and curative treatment of human AE.
