Acid Resistance of Glass Ionomer Cement Restorative Materials.

In view of the need for aesthetics, restorations of teeth will typically be completed using tooth colored restorative materials. With the advent of biomimetic restorative materials, such as glass ionomer cements (GIC), much greater emphasis is now being placed on how well such materials can resist the challenge of acids that are present in foods and drinks, or gastric contents that are regurgitated. This laboratory study compared the dissolution and behavior of five GIC materials (GC Fuji® VII, GC Fuji® Bulk, GC Fuji® IX Fast, Fuji® IX Extra and GC Equia® Forte Fil) when exposed to three acids (citric acid, phosphoric acid and lactic acid), versus ultrapure deionized water, which was used as a control. Discs of each material GIC were submerged in solutions and percentage weight changes over time determined. Subsequently, the GIC materials were also placed as a part of standardized Class II sandwich restorations in bovine teeth (n = 20), and submerged in the solutions, and the extent of GIC dissolution and protection of the adjacent tooth was scored. Weight loss increased with time and with acid concentration. Overall, the most soluble material was GC Fuji® IX Extra, while GC Fuji® IX Fast and GC Fuji® Bulk were less soluble, and the least soluble material was GC Equia® Forte Fil. The most destructive solution for both the discs and for GIC restorations in teeth was 10% citric acid, while the least destructive acid was 0.1% lactic acid. The more recent GIC materials GC Fuji® Bulk and GC Equia® Forte Fil showed increased acid resistance over the older GIC materials, and this further justifies their use in open sandwich Class II restorations in more hostile environments.

Would You Be Surprised if This Patient Died in the Next 12 Months? Using the Surprise Question to Increase Palliative Care Consults From the Emergency Department.

BACKGROUND: There is a growing movement to increase palliative care consults from the emergency department (ED) to reduce healthcare costs and improve quality of life. The surprise question is a screening tool that emergency medicine physicians may be able to use towards achieving this goal. OBJECTIVE: The objectives of this study were to increase awareness of hospice and palliative care medicine (HPM) among emergency medicine (EM) providers and to evaluate whether this heightened awareness increased palliative care consults among participating emergency medicine providers. METHODS: We conducted an anonymous convenience sample survey and two educational interventions about HPM including the surprise question among emergency medicine resident and attending physicians at a large urban public academic quaternary care center from July to November 2018. A report of palliative care consults ordered between August 1, 2017 and January 1, 2019 was generated from the electronic health records used by the hospital. The number of palliative care consults made before and after the educational intervention was compared. RESULTS: After the first educational intervention centered on the surprise question, palliative care consults from the ED increased from an average of 2.25 per month (range 0 to 8, SD: 2.38) to 12.67 per month (range 9 to 19, SD: 4.01, p < .001). CONCLUSION: Educating EM physicians about the surprise question can increase the number of palliative care consults from the ED, thereby potentially improving patient care and decreasing costs by avoiding unwanted healthcare interventions.

Clinical and financial implications of emergency department visits for synthetic marijuana.

BACKGROUND: Many users believe that synthetic cannabinoids offer a safe and legal means of getting high. However, spikes in emergency department visits have been associated with use of synthetic cannabinoids. The purpose of the current study was to document emergency department visits from three large hospitals in one metropolitan area over a two month period. METHOD: This was a retrospective chart review examining 218 patients presenting to three inner city emergency departments between March and April 2014. Data collected included demographic information, information regarding ED diagnosis and treatment, signs and symptoms, ancillary testing, ED disposition, and cost of the medical treatment. RESULTS: The majority of patients (75.7%) were discharged after ED workup, but 12.4% were admitted for medical treatment and 11.5% were admitted for psychiatric treatment. Ten patients (4.6%) were admitted to the ICU. Symptoms experienced most frequently include: hypertension, tachycardia, agitation, drowsiness, nausea, and confusion. Cluster analysis revealed four symptom clusters of individuals presenting after using synthetic cannabinoids: 1) confusion, hostility, agitation, 2) nausea, vomiting, abdominal pain, 3) drowsiness, and 4) the absence of these symptoms. CONCLUSION: This study has three important findings. First, significant ED resources are being used to treat individuals presenting due to effects of synthetic cannabis. Second, synthetic cannabis is not a benign substance. Third, while the hostile and agitated user is generally presented in the media, this study finds significant heterogeneity in presentation. Further research is needed to fully understand the implications of synthetic cannabinoid use.
