The association between PD and PLBW weight was consistent, except for exposure measurement 1, i.e. using at least one site with CAL> or =3 mm for periodontitis diagnosis, while the magnitude of this varied according to the definition established.

The extensive use of central venous catheters (CVC) in a hospital environment leads to increased iatrogenic complications, as more catheters are used enclosed and its maintenance is prolonged. Several complications are known to be related to central venous catheter, of which the uncommon cardiac tamponade (CT), hardly recognized and associated with high mortality. We present a clinical case, with favorable outcome, of a patient who developed a CT 17 days after CVC placement, and try to reflect on the measures that can be taken to reduce its incidence, as well as the therapeutic approaches to practice in the presence of a suspected CT.

Objective: to evaluate the oral health condition of pregnant/postpartum women attending public services in the city of Feira de Santana, BA, Brazil, at three different times between 2005 and 2015. Methods: this is a study socioeconomic and demographic characteristics, health condition and health care, lifestyle and oral health status of 1,245 participants obtained from a database of three previous investigations: I Intervention Study (2005-2007); II Case-Control Study (2010-2011); III Case-Control Study (2012-2015). Results: comparing the three periods, the frequency of gingivitis (24.41% versus 8.90% versus 5.77%; p<0.01) and periodontitis (44.64% vs 9.16% vs 11.55%; p<0.01) was found to decrease; the worst dental conditions regarding the number of teeth present, healthy and extracted and the DMFT index were found in period III compared to period II. Conclusion: an improvement was seen in the participants' periodontal condition over time, which coincides with the implementation of policies pertaining to women's health, oral health and income redistribution in this city.

Objective: This study aimed to compare four radiographic methods for interpreting the periodontitis in epidemiological studies on associations with systemic conditions.Methods: A database from a case-control study evaluating the association between osteoporosis and periodontitis was used to compare four different radiographic criteria (RC) with the clinical criteria (CC) for interpreting the presence of periodontal disease (PD): RC-1, one tooth; RC-2, at least two teeth; RC-3, at least three teeth; RC-4, at least four teeth, with one or more sites on the mesial or distal face presenting bone loss ≥ 3 mm, in relation to the cement-enamel junction. PD frequency and diagnostic values were calculated, along with the main association measurements (odds ratios), for the two criteria presenting highest specificity.Results: PD frequency varied according to the RC used, from 76.6% to 95.6%. RC-4 and RC-3 presented the highest specificity (30.5% and 21.0%, respectively). The sensitivity was 100% for all criteria tested. The unadjusted and adjusted odds ratios for RC-3 and RC-4 ranged from 1.13 to 1.52, without statistical significance.Conclusions: The findings showed that PD frequency may be influenced by different RCs, as well as indicating variation in the strength of the association between osteoporosis and periodontitis.
