RESUMEN
BACKGROUND: Atrophy of the posterior maxilla as a consequence of tooth loss and sinus pneumatization is a frequent condition encountered in the clinical practice. Prosthetic rehabilitation with implants in these patients often requires some kind of bone regeneration procedure to increase the bone volume. AIM: The aim of the present retrospective study is to analyze the survival and success rates of a series of implants placed in the atrophic posterior maxilla with a transcrestal osteotome procedure, without placing a bone grafting material. MATERIALS AND METHODS: From 2006 to 2014, 36 dental implants (Neoss Ltd., Harrogate, UK) were inserted in 36 patients with at least 4 mm of bone below the maxillary sinus using transcrestal osteotome sinus floor elevation and placement of collagen sponge below the sinus membrane. ISQ measurements were made after implant placement and at abutment surgery after 4 to 6 months. The vertical bone height (VBH) was evaluated in intraoral radiographs taken prior to surgery and in radiographs from annual check-up appointments 5 to 13 years after implant placement. In addition, marginal bone loss (MBL) was evaluated. RESULTS: One implant was lost after four years of prosthetic loading. The remaining 35 implants showed no complications and were loaded with single crowns after 4-6 months of healing. All 35 implants showed clinical success after 8.5 ± 2.8 years of prosthetic loading (from 5 to 13 years). The vertical bone height was 5.9 ± 1.4 mm at surgery, 9.7 ± 1.1 mm at second surgery after 4-6 months, and 8.3 ± 1.8 at the follow-up at 8.5 ± 2.8 years (from 5 to 13 years). The implant stability registered was 73.2 ± 6.2 ISQ at the surgery and 75.8 ± 3.9 at the second surgery after 4-6 months. CONCLUSIONS: The present long-term follow-up study showed that the crestal approach for sinus floor bone augmentation without additional bone grafting results in predicable bone formation and high implant survival. The osteotome technique is a valid alternative to the more invasive lateral window technique in single cases with a minimum of 4 mm of VBH below the maxillary sinus.
RESUMEN
BACKGROUND: An increasing amount of evidence confirms that abnormalities in glucose metabolism are associated with cardiovascular morbidity and mortality in acute coronary syndromes (ACS). The in-hospital management of hyperglycemic diabetic patients with ACS is complex, and the traditional clinical-organizational approaches show a high degree of heterogeneity nationwide in Italy. METHODS: The current survey (March 2016-January 2017), carried out through the Delphi method, was focused on some management issues to verify the modalities/possibilities of resolution in daily clinical practice. In addition to the 12 members of the Board, who defined the web-based questionnaire and coordinated the various stages of the process, 66 specialists, cardiologists or diabetologists, were involved in 6 Italian Regions (Lombardy, Tuscany, Lazio, Friuli-Venezia Giulia, Puglia and Sicily). Three iterative rounds of evaluation of the 24 statements included in the questionnaire were scheduled. For each statement, the median evaluation value and the degree of convergence of the Panel of specialists were determined. RESULTS AND CONCLUSIONS: The final analysis reveals two key aspects with a broad convergence of opinions: (i) the need, since admission to hospital, of a close collaboration between cardiologists and diabetologists in the assistance of high-risk patients; and (ii) the opportunity of a specific diagnostic therapeutic care pathway extended to post-discharge management, where the role of the general practitioner should be adequately emphasized.

OBJECTIVE: To evaluate the prevalence of bacterial vaginosis in a population of Italian pregnant women and to study its association with adverse pregnancy outcomes, particularly preterm delivery. STUDY DESIGN: After giving informed consent, 598 women were consecutively enrolled at their first prenatal visit (13-18 weeks of gestation). The presence of bacterial vaginosis was assessed by Gram's method at 13-18 weeks of gestation (early bacterial vaginosis) and at 28-32 weeks of gestation (late bacterial vaginosis). Univariate and multiple logistic regression models of analysis were used to assess the statistical significance of the data. RESULTS: Preterm delivery occurred in 14.7% of pregnant women positivefor bacterial vaginosis at theirfirst prenatal visit and in 6.9% of healthy women (OR 1.6, CI 1.07-2.51). In patients with bacterial vaginosis, preterm delivery occurred more often in the 36th week of gestation (78.6%). CONCLUSION: The presence of bacterial vaginosis at an early gestational age is associated with preterm delivery, although in the study population the condition did not seem to be related to great prematurity.

OBJECTIVE: To evaluate the incidence of gestational diabetes in our population and verify costs of universal screening. To assess neonatal and obstetrical outcomes with respect to maternal epidemiological characteristics. METHODS: Eight hundred and fifty-six pregnant women between 24th and 28th weeks of gestation were examined in this observational study. Universal screening with glucose challenge test was used to screen the group for gestational diabetes. History, obstetrical and neonatal outcomes were collected and then analyzed. RESULTS: Gestational diabetes was diagnosed in 6.6% of cases. Patients with at least one risk factor had a cesarean section in 50% of cases and a spontaneous vaginal delivery in 23.59% of cases (p < 0.001). The absence of any risk factor was found in 73.7% of positive glucose tolerance test and in 62.5% of affected patients. The cost of universal screening in our study, was 57,60 Euros per case identified. CONCLUSIONS: Given the high prevalence of diabetes, the high proportion of patients potentially not identified with a selective screening in this study and the relatively low cost, universal screening for gestational diabetes seems the best way to identify patients and prevent adverse obstetrical and neonatal outcomes.

The aim of the study was to identify which groups of women contribute to interinstitutional variation of caesarean delivery (CD) rates and which are the reasons for this variation. In this regard, 15,726 deliveries from 11 regional centers were evaluated using the 10-group classification system. Standardized indications for CD in each group were used. Spearman's correlation coefficient was used to calculate (1) relationship between institutional CD rates and relative sizes/CD rates in each of the ten groups/centers; (2) correlation between institutional CD rates and indications for CD in each of the ten groups/centers. Overall CD rates correlated with both CD rates in spontaneous and induced labouring nulliparous women with a single cephalic pregnancy at term (P = 0.005). Variation of CD rates was also dependent on relative size and CD rates in multiparous women with previous CD, single cephalic pregnancy at term (P < 0.001). As for the indications, "cardiotocographic anomalies" and "failure to progress" in the group of nulliparous women in spontaneous labour and "one previous CD" in multiparous women previous CD correlated significantly with institutional CD rates (P = 0.021, P = 0.005, and P < 0.001, resp.). These results supported the conclusion that only selected indications in specific obstetric groups accounted for interinstitutional variation of CD rates.

BACKGROUND: Caesarean delivery (CD) rates are commonly used as an indicator of quality in obstetric care and risk adjustment evaluation is recommended to assess inter-institutional variations. The aim of this study was to evaluate whether the Ten Group classification system (TGCS) can be used in case-mix adjustment. METHODS: Standardized data on 15,255 deliveries from 11 different regional centers were prospectively collected. Crude Risk Ratios of CDs were calculated for each center. Two multiple logistic regression models were herein considered by using: Model 1- maternal (age, Body Mass Index), obstetric variables (gestational age, fetal presentation, single or multiple, previous scar, parity, neonatal birth weight) and presence of risk factors; Model 2- TGCS either with or without maternal characteristics and presence of risk factors. Receiver Operating Characteristic (ROC) curves of the multivariate logistic regression analyses were used to assess the diagnostic accuracy of each model. The null hypothesis that Areas under ROC Curve (AUC) were not different from each other was verified with a Chi Square test and post hoc pairwise comparisons by using a Bonferroni correction. RESULTS: Crude evaluation of CD rates showed all centers had significantly higher Risk Ratios than the referent. Both multiple logistic regression models reduced these variations. However the two methods ranked institutions differently: model 1 and model 2 (adjusted for TGCS) identified respectively nine and eight centers with significantly higher CD rates than the referent with slightly different AUCs (0.8758 and 0.8929 respectively). In the adjusted model for TGCS and maternal characteristics/presence of risk factors, three centers had CD rates similar to the referent with the best AUC (0.9024). CONCLUSIONS: The TGCS might be considered as a reliable variable to adjust CD rates. The addition of maternal characteristics and risk factors to TGCS substantially increase the predictive discrimination of the risk adjusted model.
