- Objectives: The aim of the ITI Consensus Workshop on zygomatic implants was to provide Consensus Statements and Clinical Recommendations for the use of zygomatic implants.Materials and methods: Three systematic reviews and one narrative review were written to address focused questions on (1) the indications for the use of zygomatic implants; (2) the survival rates and complications associated with surgery in zygomatic implant placement; (3) long-term survival rates of zygomatic implants and (4) the biomechanical principles involved when zygoma implants are placed under functional loads. Based on the reviews, three working groups then developed Consensus Statements and Clinical Recommendations. These were discussed in a plenary and finalized in Delphi rounds.Results: A total of 21 Consensus Statements were developed from the systematic reviews. Additionally, the group developed 17 Clinical Recommendations based on the Consensus Statements and the combined expertise of the participants.Conclusions: Zygomatic implants are mainly indicated in cases with maxillary bone atrophy or deficiency. Long-term mean zygomatic implant survival was 96.2% [95% CI 93.8; 97.7] over a mean follow-up of 75.4 months (6.3 years) with a follow-up range of 36-141.6 months (3-11.8 years). Immediate loading showed a statistically significant increase in survival over delayed loading. Sinusitis presented with a total prevalence of 14.2% [95% CI 8.8; 22.0] over a mean 65.4 months follow-up, representing the most common complication which may lead to zygomatic implant loss. The international experts suggested clinical recommendations regarding planning, surgery, restoration, outcomes, and the patient's perspective.

- Computed Tomography Coronary Angiography (CTCA) is a rapid, non-invasive diagnostic tool for coronary artery disease (CAD). Rapid Access Chest Pain Clinics (RACPC) were introduced in UK in 2000, in order to assess rapidly patients with chest pain. To evaluate the use of CTCA as initial work-up for unstable angina pectoris in a primary care-based RACPC. Eighty-eight (n=88) patients were examined by a consultant cardiologist and referred for CTCA if indicated. CTCA was performed with a 640 slices, 320-row CT scanner. Thirty-five (n=35) patients were discharged without further investigations; 50 (mean age 59.8 years; 24 male) were referred for CTCA and 3 were referred directly for an invasive angiography (IA). Following CTCA, 17 patients were discharged. Seventeen (n=17) patients with no history of CAD, but with positive CTCA findings and eleven (n=11) patients with known CAD but without new lesions on CTCA were discharged after optimisation of medical treatment. Five (n=5) of the 50 patients eventually underwent IA; 2 were referred for CABG; 3 continued with medical treatment. No major adverse cardiac events were recorded in a 6-months' follow up period. The cost for each patient who underwent CTCA was £1,087; 94% of patients rated their experience as good or excellent. The time interval from RACPC visit-to-definitive diagnosis was <3 weeks in 50% of patients, <6 weeks in 90%. Use of CTCA as initial investigation in Primary Care, is both clinically and cost-effective. CTCA should be considered in the initial diagnostic work-up of unstable angina pectoris patients, with or without prior history of CAD.
