J Contemp Dent Pract. 2017 Mar 01;18(3):214-217 Authors: Priyank H, Pandey V, Bagul A, Majety KK, Verma P, Choudhury BK Abstract INTRODUCTION: Endodontic treatment removes all pathogens, such as Enterococcus faecalis from pulp and root canals. The aim of this study is to assess the usefulness of sodium hypo-chlorite (NaOCl) in removing E. faecalis from the root canal used with three different irrigation methods. MATERIALS AND METHODS: This study was conducted on freshly extracted maxillary incisors. After biomechanical preparation, root canals were injected with E. faecalis. Three groups were made which contained 30 teeth in each group; 2 mL of NaOCl solution was used for irrigation followed by agitation with K-files in group I; 2 mL of NaOCl solution was used for irrigation and ultrasonic agitation was done in group II. In group III, an alternate irrigation with NaOCl and 3% hydrogen peroxide was done. The fourth group (control) was irrigated with sterile saline solution. E. fae-calis bacteria were sampled to the root canals with paper points and were transferred to tubes that contained 5 mL of brain heart infusion broth. Tubes were incubated and the presence of broth turbidity was suggestive of bacteria remaining in the root canal. RESULTS: All three groups showed no statistically significant difference. However, difference existed between experimental groups and control groups. CONCLUSION: The author concluded that all three methods of application of NaOCl were effective in disinfecting the root canal than the saline solution. CLINICAL SIGNIFICANCE: No single irrigant has 100% efficiency. Thus by this study, a best irrigating solution with maximum properties can be established.

Ugeskr Laeger. 2014 Nov 03;176(45): Authors: Nordholm-Carstensen A Abstract Cannabinoid hyperemesis syndrome (CHS) is characterised by unrelenting nausea, recurrent vomiting, abdominal pain and compulsive, hot bathing behaviour. The symptoms contrast the traditional effects associated with cannabis use. We report a "textbook example" of a 26-year-old man with CHS. CHS is an important differential diagnosis to consider in patients with similar symptoms and the distinctive symptom relief in hot water. Early recognition may prevent extensive, unnecessary medical examinations and frequent hospital admissions. PMID: 25394844 [PubMed - indexed for MEDLINE]
