Endodontic Retreatment of Teeth With Uncertain Endodontic Prognosis Versus Dental Implants: 5-year Results From a Randomised Controlled Trial

PURPOSE. To ascertain whether it is better to endodontically retreat a previously endo-dontically treated tooth with periapical pathology and/or symptoms and an uncertain prognosis, or to replace the tooth with a single implant-supported crown. MATERIALS AND METHODS. Twenty patients requiring treatment of a previously endodon-tically treated tooth with periapical pathology and/or symptoms of endodontic origin and an uncertain prognosis, as judged by the recruiting investigator, were randomly allocated to endodontic retreatment (endo group; 10 patients) or tooth extraction and replacement with an implant-supported crown (implant group; 10 patients) according to a paral-lel-group design at a single centre. Patients were followed up to 5 years after treatment completion. Outcome measures were: procedure failure; complications; marginal bone level changes at both teeth and implants; radiographic endodontic success (teeth only); number of patient visits and days to complete treatment; chairside time; costs; and ae-sthetics, as assessed using the pink aesthetic score (PES) for the soft tissues and the white aesthetic score (WES) for the tooth/crown by independent assessors. RESULTS. One patient from the endo group dropped out. One endodontically retreated tooth fractured. There were no statistically significant differences in treatment failure between groups (difference in proportions = 0.1; 95% CI-0.18 to 0.35; P = 1.00). Three endo group patients had one complication each versus one complication in the implant group, the difference not being statistically significant (difference in proportions = 0.2; 95% CI-0.17 to 0.51; P = 0.582). The mean marginal bone levels at endo retreatment/implant insertion were 2.10 ± 0.66 mm for the endo and 0.05 ± 0.15 mm for the implant group. Five years after treatment completion, teeth lost on average 0.60 ± 0.96 mm and implants 0.56 ± 0.77 mm, the difference not being statistically significant (mean difference =-0.05 mm; 95% CI:-0.95 to 0.86; P = 0.914). Of the four teeth that originally showed periapical radiolucency, one was lost, two displayed complete healing, and one showed radiographic improvement. There were no statistically significant differences in the number of patient visits (endo = 6.7 ± 0.7; implant = 6.1 ± 0.7; mean difference = 0.6; 95% CI:-0.1 to 1.3 P = 0.106). However, it took significantly more days (endo = 61 ± 13.0; implant = 191.4 ± 75.0; mean difference =-130.4; 95% CI:-184.5 to-76.4; P < 0.001) but less chairside time (endo = 628 ± 41.4 min; implant = 328.5 ± 196.4 min; mean difference =-299.5; 95% CI:-441.3 to 1.0; P = < 0.001) to complete the rehabilitation. Implant treatment was significantly more expensive (endo = 1440 ± 549.7; implant = 2099 ± 170.3; mean difference = 659; 95% CI: 257.2 to 1060.8; P = 0.004). Five years after treatment completion, mean PES were 12.3 ± (1.3) and 8.9 ± 2.2 and mean WES were 8.1 ± 1.4 and 7.1 ± 1.7 in the endo group and implant group, respectively. Soft tissues aesthetics (PES) was significantly better at endodontically retreated teeth (mean difference-3.4; 95% CI-5.1 to-1.6; P (t-test) = 0.001), whereas no significant differences were observed between treatments in tooth aesthetics (WES) (mean difference =-1.0; 95% CI-2.6 to 0.5; P (t-test) = 0.178)

Evaluation of the Performance of ACR TI-RADS Also Considering Those Nodules with No Indication of FNAC: A Single-Center Experience

Background: Several US risk stratification score systems (RSSs) have been developed to standardize a thyroid nodule risk of malignancy. It is still a matter of debate which RSS is the most reliable. The purpose of this study is to evaluate: (1) the concordance between the American College of Radiology TI-RADS (ACR TI-RADS) and fine needle aspiration cytology (FNAC), (2) the cancer rate in the ACR TI-RADS categories, (3) the characteristics of nodules evaluated by FNAC even if not formally indicated according to ACR TI-RADS ('not indicated FNACs"). Methods: From January 2021 to September 2022, patients attending the Endocrinology Unit of the CTO Hospital of Rome for evaluation of thyroid nodules were included. Results: 830 nodules had negative cytology, belonging to TIR2 and TIR1C. One hundred and thirteen nodules were determined to be suspicious for or consistent with malignancy belonging to TIR3B/TIR4/TIR5. Of this last group, 94% were classified as TR4/TR5 nodules. In total, 87/113 underwent surgery. Among these, 73 had histologically proven cancer, 14 turned out to be benign. "Not indicated FNACs" was 623. Among these, 42 cancers were present. Conclusions: This study confirmed the diagnostic power of ACR TI-RADS. In addition, these data suggest revising the ACR TI-RADS indication to FNAC, especially for TR4

Treatment of peripheral arterial disease in diabetes: a consensus of the Italian Societies of Diabetes (SID, AMD), Radiology (SIRM) and Vascular Endovascular Surgery (SICVE).

AbstractDiabetic foot (DF) is a chronic and highly disabling complication of diabetes. The prevalence of peripheral arterial disease (PAD) is high in diabetic patients and, associated or not with peripheral neuropathy (PN), can be found in 50% of cases of DF. It is worth pointing out that the number of major amputations in diabetic patients is still very high. Many PAD diabetic patients are not revascularised due to lack of technical expertise or, even worse, negative beliefs because of poor experience. This despite the progress obtained in the techniques of distal revascularisation that nowadays allow to reopen distal arteries of the leg and foot. Italy has one of the lowest prevalence rates of major amputations in Europe, and has a long tradition in the field of limb salvage by means of an aggressive approach in debridement, antibiotic therapy and distal revascularisation. Therefore, we believe it is appropriate to produce a consensus document concerning the treatment of PAD and limb salvage in diabetic patients, based on the Italian experience in this field, to share with the scientific community

The pathogenesis of Charcot neuroarthropathy: current concepts

The pathogenesis of Charcot neuroarthropathy (CN) has been poorly understood by clinicians and scientists alike. Current researchers have made progress toward understanding the cause of CN and possible treatment options. The authors review the current literature on the pathogenesis of this debilitating disorder and attempt to explain the roles of inflammation, bone metabolism, and advanced glycation end products

A study of prognostic factors in Chinese patients with diabetic foot ulcers

Objective: Few studies have identified factors as predictors of clinical prognosis of patients with diabetic foot ulcers (DFUs), especially of Chinese patients. In this study, we assessed the prognostic factors of Chinese patients with DFUs. Methods and materials: This was a retrospective study (January 2009–January 2011) of 194 DFUs conducted in an inpatient population at PLA 454 Hospital in Nanjing, China, to determine the prognostic influential factors of DFUs in Chinese patients. All of the studied patients were grouped into an amputation group, a non-healing group, and a cured group, according to the clinical prognosis. Patient parameters, including gender, age, smoking habits, education level, family history of diabetes mellitus, medical history, duration of foot lesions and complications, ankle-brachial index (ABI), transcutaneous oxygen pressure (TcPO2), urinary albumin/creatinine ratio (Alb/Cr), fundus oculi, electrocardiogram, DFU characteristics, bacterial nature, and neuropathy, were cross-studied among the three groups. Results: Compared with the other two groups, the amputation group showed a higher number of males, older in age, lower ABI and TcPO2 levels, higher Wagner wound grading and size, and significantly higher urinary Alb/Cr ratio, blood urea nitrogen, serum creatinine, white blood cell count, and erythrocyte sedimentation rate. Compared to the cured group (162 patients), more patients with an older age, smoking, family history of diabetes mellitus, medical history of foot ulcerations, lower ABI and TcPO2 levels, higher urine Alb/Cr ratio, and serum creatinine were found in the non-healing group. Regression analysis was used to study the correlation between various factors and clinical prognosis, and the results were as follows: age, Wagner wound classification, and heel ulcerations were negatively correlated to the DFU prognosis, whereas the female population, ABI, and TcPO2 were positively correlated with DFU prognosis. Conclusion: In this retrospective study, we conclude that the DFU prognosis may be related to age, gender, wound location (heel), Wagner wound classification, ABI, and TcPO2 levels in the Chinese population

Proinflammatory Modulation of the Surface and Cytokine Phenotype of Monocytes in Patients With Acute Charcot Foot

Despite increased information on the importance of an inappropriate inflammatory response in the acute Charcot process, there has been no previous attempt to define the specific pathways that mediate its pathogenesis. Here, the role played by monocytes was analyzed
