Purpose: To establish the incidence of chipping of zirconia-based restorations, either implant or tooth supported in a retrospective study. Material and methods: Sixty patients received 222 cemented units of zirconia-based restorations. One hundred thirteen units were cemented on teeth, 97 on implants and 12 units were pontics. After the delivery of the restorations, during the recalls, the patients were examined in regard to the presence of chipping of the veneering ceramic. Location of the restoration, the type of support and the design of the restoration were assessed as possible factors influencing chipping rate. Results: During an observation period of up to 5,5 years, 27 (12,16%) zirconia-based units showed chipping of the veneering ceramic. A total of 14 units had to be remade, resulting in a survival rate of 93,69% of the zirconia-based restorations. The chipping rate seemed to be higher in restorations on implants than those supported by teeth. In the molar region chipping occured twice as often as in the premolar and front regions (15,83% vs 7,84%). An increased chipping rate was observed in multi-unit restorations (13,95%) as compared to single-unit restorations (9,67%). Conclusion: Chipping of the porcelain veneering is the most frequent complication of zirconia-based restorations. They should be recommended with care in the molar region, especially as multi-unit restorations.

Uterine Torsion

A study was carried out to find out the retrospective incidence of uterine torsion in buffaloes among obstetrical cases in Amul milk shed area and factors influencing it. Data on 1,13,772 obstetrical cases attended from January 2017 to June 2018 by Amul Veterinarians were collected. Moreover, 50 buffaloes suffering from uterine torsion were taken up during July-December, 2018 to know the side, site, degree of uterine torsion, parity as well as sex and viability of the calf and the dam after detorsion/Caesarean section in the same area. In the retrospective study, a total of 2000 cases of uterine torsion were recorded among total 1,13,772 bovine obstetrical cases, which encompassed 1.76%. Of the 2000 cases, 92.20 (1844) percent torsions were found in buffaloes only. Among 57,111 obstetrical cases attended in buffaloes, the incidence of uterine torsion was 3.23%. Moreover, the region/center-wise incidence of torsion cases varied from 1.30–19.36%. The highest incidence of uterine torsion was found in Anand region (19.36 %) followed by Kathlal (11.23 %) and Mahemdabad (10.14 %) regions, while the lowest incidence was in Virpur (2.06%), Petlad (1.46%) and Piplata (1.30%). It was concluded that buffaloes mostly experience right side (100%), post-cervical (82%) uterine torsion of 270–360° (66%), at full term of gestation (70%)with lower survivability of the calves (30%), however, the survival rate of the dams post-treatment was 90%.

Number Of Individuals

<b><i>Background:</i></b> The increase in life expectancy and low mortality have doubled the number of individuals older than 65 in the last 30 years. <b><i>Methods:</i></b> We conducted a retrospective study of 101 patients older than 80 years of age treated by low digestive hemorrhage (LDH) in an emergency department during 2018. Sociodemographic variables were evaluated, as well as comorbidity and survival at 18 months. Survival was assessed by a Kaplan-Meier test. <b><i>Results:</i></b> 52.5% of the subjects were women. The average comorbidity of the sample was 1.97. The survival rate per year was 60%. The finding on colonoscopy shows no association with mortality. However, those patients on anticoagulant/antiplatelet therapy have a higher survival rate. <b><i>Conclusion:</i></b> Survival per year is high, so urgent colonoscopy for an LDH should be performed after evaluating the patient’s stability and functional status in a scheduled and outpatient manner.

Clinical Records

This retrospective study evaluated the survival rate of short, sandblasted acid-etched surfaced implants with 6 and 8 mm lengths with at least 120 days of follow-up. Data concerning patient, implant and surgery characteristics were retrieved from clinical records. Sandblasted and acid-etched (SLA)-surfaced tissue-level 6 mm (TL6) or 8 mm (TL8) implants or bone-level tapered 8 mm (BLT8) implants were used. Absolute and relative frequency distributions were calculated for qualitative variables and mean values and standard deviations for quantitative variables. A Cox regression model was performed to verify whether type, length and/or width influence the implant survival. The cumulative implant survival rate was assessed by time-to-event analyses (Kaplan–Meier estimator). In all, 513 patients with a mean age of 58.00 ± 12.44 years received 1008 dental implants with a mean follow-up of 21.57 ± 10.77 months. Most implants (78.17%) presented a 4.1 mm diameter, and the most frequent indication was a partially edentulous arch (44.15%). The most frequent locations were the posterior mandible (53.97%) and the posterior maxilla (31.55%). No significant differences were found in survival rates between groups of type, length and width of implant with the cumulative rate being 97.7% ± 0.5%. Within the limitations of this study, the evaluated short implants are a predictable option with high survival rates during the follow-up without statistical differences between the appraised types, lengths and widths.

Objectives:The present study was conducted in a vocational integration service of a northern Italian town with two major aims: to assess vocational integration programs undertaken from 1stJanuary 2004 to 1stJanuary 2007; and to identify job tenure-associated predictors.Methods:This is a retrospective study; we collected data such as gender, age, duration, type and outcome of the vocational integration program, and number of interventions performed by the vocational integration service. Self-report questionnaires were also used to assess the satisfaction of users, caregivers, practitioners, and of the company contacts involved in the study.Results:The service has enrolled 84 users during the observation period. Out of these users, 64.3% of them still had their jobs after three years. Users, caregivers and company contacts expressed high levels of satisfaction for the support received by the vocational integration service. The company expressed less satisfaction for the collaboration received by the Departments of Mental Health (DMHs) that coached the users. The only variable associated to the outcome was the number of interventions that the users received before their placement on the job.Conclusions:Despite all the limits of this study, its results show that the chance of taking advantage of a supported job placement service has likely proven itself effective in helping people with mental disorders to obtain and maintain a competitive employment. Our results, however, also point to the necessity of implementing newer strategies meant to develop a greater integration among all services dealing with mentally ill people.
