ABSTRACT
The aim of this systematic review was to test the following hypotheses: (1) that there is no difference in implant survival rate between individuals with overweight or obesity and those who are within the ideal weight range; (2) that there are no differences between these groups regarding indicators of peri-implant health. Two independent reviewers performed a literature search of the PubMed/MEDLINE, Scopus, and Cochrane Library databases for studies published up to April 1, 2018. A meta-analysis was performed to determine the risk difference for implant failure and mean difference for marginal bone loss, probing depth, and bleeding on probing. Six studies were selected for review, involving a total of 746 patients with 986 implants: 609 in overweight or obese individuals and 377 in individuals within the ideal weight range. The findings of this systematic review indicate that the first hypothesis should be accepted, since no statistically significant difference in implant survival rate was found between individuals with overweight/obesity and those within the ideal weight range (P=0.64). The second hypothesis was rejected, as the review indicated a difference in marginal bone loss (P<0.00001), probing depth (P<0.00001), and bleeding around dental implants (P<0.00001).

The aim of this systematic review was to identify randomized, placebo-controlled clinical trials investigating the effectiveness of corticosteroids in the control of pain, oedema, and trismus following third molar surgery, and to analyse the effects of the type of drug administered and the time and route of drug administration on the outcomes of interest. Searches were performed in the PubMed, Scopus, and Cochrane Library databases. This review was structured according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. The search identified 1223 studies. After assessing eligibility based on the inclusion and exclusion criteria, 17 studies were selected for the qualitative analysis (a total of 730 patients aged 15-45 years). Ten studies were included in the meta-analysis, which was performed using Review Manager software. The corticosteroids were effective in controlling pain (P=0.002; mean difference -17.38, 95% confidence interval -24.81 to -9.95) and trismus (P<0.00001; mean difference 6.10, 95% confidence interval 3.42 to 8.77). With the exception of the submucosal route, the route of administration did not appear to affect the outcomes. The administration of a corticosteroid in the preoperative phase was superior to its use in the postoperative phase for the control of trismus.

A 46-year-old female patient with chronic Chagas' myocarditis without heart failure was submitted to chemotherapy because of Hodgkin's disease. During treatment the frequency of polymorphic ventricular extrasystoles raised and the patient died by a sudden cardiac arrest. Autopsy revealed chronic Chagas myocarditis with an acute exacerbation. Nests of amastygotes with a density of up to 14 pseudocysts/cm2 were found in the myocardium, although restricted to the septum and left ventricular posterolateral wall. Extensive histologic examination did not reveal parasites in other locations. This favors the concept of a localized exacerbation of Chagas' disease due to immunosuppression developing from a persistent parasitic focus in the heart. Although this reactivation during chemotherapy of malignant disease is rarely reported in literature, a careful monitoring of patients with positive Chagas' serology during chemotherapy is recommended.
