We describe a simple method to create a reusable and customizable dental guard using readily available materials. Our method does not require an extra patient visit and does not add operative time. Furthermore, our guard is rigid, which allows force to be distributed over adjacent teeth, unlike soft mouth guards. 相似文献

Objective
Cervical lymphadenopathy is a common pediatric problem; reactive hyperplasia, specific infective agents, and malignancy are mainly the differential diagnosis. The aim of our study was to detect the prevalence of Epstein-Barr virus infection among children who complained of cervical lymphadenopathy and also to evaluate the clinical manifestations of the disease in pediatric patients.Methods
One hundred and sixty children presented with cervical lymphadenopathy were subjected to Epestien-Barr Virus (EBV) serology testing. Cases that showed positivity to heterophile antibody test, and/or EBV-specific antibodies; IgM against viral capsid antigen (VCA-IgM) and IgG against viral capsid antigen (VCA-IgG) were evaluated clinically for manifestations of the disease.Results
Twenty-four cases (15%) showed positivity to EBV serology, all of them had posterior cervical lymph nodes enlargement, 70.8% had fever, 66.6% had tonsillo-pharyngitis, 58.3% had splenomegaly, 25% had hepatomegaly, 41.6% had generalized lymphadenopathy, while skin rash was detected in 12.5%, and both palatal petechiae and palpebral edema were detected in 8.3%.Conclusions
EBV infection is not a rare cause of cervical lymphadenopathy in children. Posterior cervical lymphadenopathy in pediatric age group may represent a password for suspicion of EBV infection, while other clinical manifestations of the disease may include hepato-splenomegaly, skin rash, palpebral edema and palatal petechiae. 相似文献996.

Suicidal behavior on the subway often involves young people and has a considerable impact on public life, but little is known
about factors associated with suicides and suicide attempts in specific subway stations. Between 1979 and 2009, 185 suicides
and 107 suicide attempts occurred on the subway in Vienna, Austria. Station-specific suicide and suicide attempt rates (defined
as the frequency of suicidal incidents per time period) were modeled as the outcome variables in bivariate and multivariate
Poisson regression models. Structural station characteristics (presence of a surveillance unit, train types used, and construction
on street level versus other construction), contextual station characteristics (neighborhood to historical sites, size of
the catchment area, and in operation during time period of extensive media reporting on subway suicides), and passenger-based
characteristics (number of passengers getting on the trains per day, use as meeting point by drug users, and socioeconomic
status of the population in the catchment area) were used as the explanatory variables. In the multivariate analyses, subway
suicides increased when stations were served by the faster train type. Subway suicide attempts increased with the daily number
of passengers getting on the trains and with the stations’ use as meeting points by drug users. The findings indicate that
there are some differences between subway suicides and suicide attempts. Completed suicides seem to vary most with train type
used. Suicide attempts seem to depend mostly on passenger-based characteristics, specifically on the station’s crowdedness
and on its use as meeting point by drug users. Suicide-preventive interventions should concentrate on crowded stations and
on stations frequented by risk groups. 相似文献
