Background To report the early outcomes of cone beam computed tomography (CBCT) using last generation 3D C-arm in patients undergone advanced endovascular aortic aneurysm repair (AdEVAR) and to identify risk factors that may predict any un-planned procedures. Methods Patients undergone AdEVAR between December 2017 and December 2018 were enrolled. Final CBCT was performed in all patients after digital subtraction angiography. Primary end points were the incidence of any positive findings and the following unplanned procedures intended as any endovascular manoeuvre performed to fix such technical defect. The secondary endpoints were comparison of outcomes between patients with positive findings undergone unplanned procedure (Group A) versus patients without findings (Group B). Results 132 patients underwent endovascular treatment for aortic aneurysm. Of these, 22 (33%) fenestrated-branched endovascular aneurysm repairs (F-BEVAR), 21 (29%) EVAR with iliac branch devices, 19 (26%) abdominal and 10 (14%) thoracic EVAR were included in the study. Unplanned procedures after CBCT were necessary in 22 patients (31%). Patients in both groups were similar excepted for BMI >25 kg/m2 (55% vs. 26%), hostile iliac anatomy (64% vs. 32%) and previous aortic treatment (73% vs. 32%) (P Conclusion The use of CBCT, especially in challenging scenarios, can reveal technical defects and may potentially limit the need for late reintervention. Patients undergone previous aortic surgery should be carefully evaluated and routine CBCT should be performed.

Objective: The introduction of new endograft models improved long-term results of abdominal aortic aneurysm (AAA) endovascular repair (EVAR), but most of them maintained an old and unchanged design: a short body and long legs shifting up the flow divider. This study assessed the long-term results of EVAR with unimodular endoprosthesis fixed at the aorto-iliac bifurcation (Anatomical FiXation), in a large, unselected cohort. Materials and Methods: In a single-center, retrospective cohort study, 623 patients selectively treated between 1999 and 2016, were analyzed. Follow-up protocol included at least a computed tomography angiography within 3 months and a duplex ultrasound and clinical exam yearly. All enrolled patients were analyzed by 2020. The primary outcomes were technical success, clinical success, and survival. Secondary outcomes included survival-free from late-open-conversion (LOC), reintervention, and endoleaks. Results: Median age was 74±11 years and the follow-up 93±54 months. The technical success was achieved in 99.4% and the 30-day clinical success was 98.4%. A 5-year clinical success of 97.7% was registered and at 10 years success was 96.7%. The overall survival at 1, 5, 10, and 15 years was 92.4%, 79.5%, 64.9%, and 45.5%, respectively. Six (0.98%) AAA-related death were registered, 3 caused by infection of the endograft and 3 for secondary rupture. LOCs were 9 (1.47%) and reintervention-free survival at 1, 5, 10, and 15 years were 88.4%, 78.0%, 76.2%, and 74.6%, respectively. Freedom from endoleaks was 88.8% at 1 year and 72.7% at 15 years. A total of 63 high-flow endoleaks were registered (43 type I, 7 type IIIa, 12 type IIIb, and 1 type Ib+IIIb). No migrations were recorded, and the graft limb thrombosis rate was 1.14%. From a multivariate analysis resulted that long-term clinical success appeared to be reduced in patients affected by diabetes [odds ratio (OR) 0.24; p=0.04] and in presence of calcified and thrombotic iliac accesses (OR 0.16; p=0.006). Conclusion: EVAR with the Anatomical FiXation was confirmed to be safe, feasible, and effective to prevent AAA rupture in the long term as well. However, the overall survival remains afflicted by cardiovascular accident. The original concept of unibody bifurcated design allowed a very low rate of graft thrombosis and zeroed the risk of migration and related reintervention.

A 58-year-old man with a history of aortic and mitral mechanical valve replacement was referred to our hospital for symptomatic chronic heart failure. In 1988, he had undergone open surgical correction of an isthmic aortic coarctation (CoA), with the creation of an extra-anatomic bypass from the left subclavian artery to the descending thoracic aorta. The following findings were found: severe mitral valve failure with perivalvular leakage, severe aortic valve stenosis, pulmonary hypertension, distal anastomotic aneurysm with the apparent occlusion of the CoA. A thoracic endovascular aneurysm repair was performed. A postoperative high-pressure leak with no evident signs of ineffective sealing was observed. Computed tomography angiography (CTA) 3D reconstruction demonstrated the recanalization of the CoA. A second procedure was planned. The CoA was anterogradely cannulated. Three coils were deployed into the aneurysmal sac, followed by a vascular plug, positioned on the coarctation conduit, but it failed to anchor and dislocated into the sac. A second plug was deployed, but it also partially dislocated. Finally, a patent foramen ovale occluder device was deployed to occlude the communication. The final angiogram showed the complete occlusion of the coarctation and correction of the leak, which was confirmed by a 6-month post-operative CTA.

AIMS To investigate the clinical performance of regenerative periodontal surgery in the treatment of furcation defects versus open flap debridement (OFD) and to compare different regenerative modalities. MATERIAL AND METHODS A systematic search was conducted to identify RCTs evaluating regenerative surgical treatment of furcations with a minimum of 12-month follow-up. Three authors independently reviewed, selected and extracted data from the search conducted and assessed risk of bias. Primary outcomes were tooth loss, furcation improvement (closure/conversion) (FImp), gain of horizontal bone level (HBL) and attachment level (HCAL). Secondary outcomes were gain in vertical attachment level (VCAL), probing pocket depth (PPD) reduction, PROMs and adverse events. Data were summarized into Bayesian standard and network meta-analysis in order to estimate direct and indirect treatment effects and to establish a ranking of treatments. RESULTS The search identified 19 articles, reporting on 20 RCTs (19 on class II, 1 on class III furcations) with a total of 575 patients/787 defects. Tooth loss was not reported. Furcation closure ranged between 0% and 60% (10 trials), and class I conversion from 29% to 100% (six trials). Regenerative techniques were superior to OFD for FImp (OR = 20.9; 90% CrI = 5.81, 69.41), HCAL gain (1.6 mm), VCAL gain (1.3 mm) and PPD reduction (1.3 mm). Bone replacement grafts (BRG) resulted in the highest probability (Pr = 61%) of being the best treatment for HBL gain. Non-resorbable membranes + BRG ranked as the best treatment for VCAL gain (Pr = 75%) and PPD reduction (Pr = 56%). CONCLUSIONS Regenerative surgery of class II furcations is superior to OFD. FImp (furcation closure or class I conversion) can be expected for the majority of defects. Treatment modalities involving BRG are associated with higher performance.

Objective: The aim of this study was to evaluate aortic remodelling and associated complications in patients treated by thoracic endovascular aneurysm repair (TEVAR) for blunt traumatic aortic injuries (BTAI). Methods: This was a retrospective, observational, multicentre study. Remodelling was considered as aortic diameter variations of >2 mm and distal graft and aortic axis angle modification measured by computed tomography angiography (CTA). The predefined levels of measurement were the proximal end of the graft (D1: landing in zone [LZ] 2; D2: LZ 3); distal end (D3); and control measurement (D4) 15 mm beyond D3. Survival, procedure, graft, and/or radiation exposure related complications were registered. CTA was required within three months and at one, six, and 10 years post-operatively. Results: Between 2004 and 2017 52 patients were treated; 47 were included for remodelling analysis (five immediate deaths were excluded); median age was 47 years (range 20–80 years). Mean TEVAR oversizing was 19.6% ± 9.7% (range 5%–35%). Following a median follow up of 67.4 ± 56.1 months (range 14–153 months) survival at one, three, six, and 10 years was 90.4% (standard error [SE] 4.1%), 88.3% (SE 4.5%) 84.8% (SE 5.5%), and 84.8% (SE 5.5%), respectively. There were no procedure/graft related complications except for one late intramural haematoma that required re-intervention. Freedom from aortic remodelling at one, six, and 10 years was 85.1% (SE 5.2%), 30.9% (SE 8.6%), and 24.7% (SE 8.8%), respectively. The increase in D1/D2 and D3 diameters were influenced by time from intervention (both p

Objective Target vessel instability is a relevant complication after thoracoabdominal aortic aneurysms branched endovascular aortic repair (BEVAR). Long-term bridging stent-graft (BSG) durability has already been established, but the incidence of long-term complications as component fractures was not deeply investigated. This paper aims to assess BSG fracture incidence and risk factors after BEVAR. Methods This was a dual-center observational retrospective cohort study. Data of each patient treated with BEVAR between April 2008 and December 2019 were prospectively collected. The primary outcome was the incidence of BSG fracture during follow-up. A logistic regression analysis was performed, including preoperative and postoperative measurements as well as intraoperative details to identify potential risk factors. Results Two hundred ninety-five target visceral vessels in 91 patients were considered suitable for cannulation. Technical success was 96.9% (286/295 target visceral vessels). The median follow-up was 32.5 months (interquartile range, 14.3-50.1 months). Five BSG fractures (1.75%; 5/286) were detected. Four BSG fractures involved the superior mesenteric artery, and one the celiac trunk. Four different types of fractured stents were detected during follow-up: two Advanta, one BeGraft, one Fluency, and one Viabahn. The median time to BSG fracture was 28.2 months (interquartile range, 11.7-50.8 months). The use of multiple stents (P = .030) and different stent types on the same vessel (P = .004) were associated with BSG fracture at univariable analysis. Using bare-metal stents for distal relining (P = .045) was the only significant factor predisposing to BSG fracture at multiple logistic regression. Conclusions BSG fracture is a rare but severe complication after BEVAR. It is not related to the stent type used as bridging stent, and it is hardly predictable based on preoperative anatomy. Using multiple and different stents on the same vessel and relining the bridging stents with bare-metal stents may increase BSG fracture risk. A strict computed tomography angiography follow-up remains the best strategy to detect target vessel instability.

Purpose To evaluate the Covera Plus (Bard, Tempe, Arizona) covered stent as a bridging stent in branched thoraco-abdominal endovascular aneurysm repair (BEVAR). Materials and Methods Retrospective analysis of 112 self-expandable stents was performed at 2 university centers between August 2017 and March 2019. Thirty-one consecutive BEVAR procedures were studied (21 males; mean age, 75 years; 29 American Society of Anesthesiologists grade III/IV) with 119 patent target vessels (7 did not receive the studied device). Primary endpoints were technical success, branch instability, and primary/secondary clinical success. Secondary endpoints included primary/secondary patency and any adverse events. Results Technical success was 100%. Median follow-up was 12 months (interquartile range, 6–14 months). Branch instability was registered twice (2/112), due to immediate renal occlusion and type Ic endoleak; no additional events occurred during the follow-up. Primary clinical success was 84%. There were 2 immediate deaths, 1 upper limb ischemia, 1 hemorrhage from splenic artery, and 1 type Ic endoleak; these last 3 events were successfully treated, with a secondary clinical success of 100% that was maintained during the follow-up. One late death occurred. Primary patency was 99% (111/112) and 100% (105/105) within 30 days and at the end of the study period,respectively. Adverse events included 4 acute kidney injuries and 2 spinal cord ischemia. No type I/III endoleaks, occlusion, fracture, or dislodging were diagnosed after 30 days. Conclusions The stent graft seems safe and effective for bridging in BEVAR with low branch instability and high patency rate. Longer follow-up is required to confirm these promising results.

Background The diabetic foot ulcer (DFU) is a high prevalence complication that significantly impairs the health-related quality of life (HRQoL) and is characterized by prolonged hospital length of stay (LOS). The impact of the micro-fragmented autologous adipose tissue injection at the minor amputation wound in the case of DFU (MiFrAADiF) on HRQoL and LOS compared to the standard care has not been determined yet. Methods This was a two-arm, 6-month, individually randomized controlled single-center clinical trial. A 1:1 randomization to local injection of autologous micro-fragmented adipose tissue (treatment group; n=57) or standard clinical care (control group; n=57) was performed. The primary objective was the HRQoL. The secondary endpoint was the LOS. HRQoL was assessed with the Medical Outcomes Study 36-item Short-Form Health Survey which provides 2 scores focused on physical (PCS) and mental functioning (MCS). The trial was registered in ClinicalTrials.gov (NCT03276312). Results The type of treatment (p=0.009) and the time elapsed since surgery (p= 0.0000) demonstrated a significant improvement on PCS. The MCS improvements resulted in a non-significant association with treatment (p= 0.21). The time elapsed since surgery showed a significant influence on the MCS (p= 0.0000). The mean LOS was 16.2 days and 24.4 days for the treatment and the control group respectively (p= 0.025). Conclusions The MiFrAADiF trial demonstrated a significant improvement in terms of physical HRQoL and a significant reduction of the hospital length of stay after injection of micro-fragmented autologous adipose tissue in diabetic patients' minor amputations wound.

Intraoral ultrasonography has been widely employed for the preoperative assessment of tumor margins due to its capability to evaluate depth of invasion (DOI) and tumor thickness (TT). Recently, a novel ultrasonographic technique, ultra-high frequency ultrasound (UHFUS) has been increasingly applied to the study of oral lesions. This study evaluates the potential application of intraoral UHFUS to assess DOI and TT parameters of oral squamous cell carcinoma (OSCC) lesions. Patients clinically suspected of OSCC lesions were enrolled and underwent an intraoral UHFUS examination preoperatively. The parameters of TT, DOI, echogenicity, and vascularization were assessed. The parameters of TT and DOI as evaluated by means of UHFUS were compared to histology, which was set as the benchmark. Ten patients in total were enrolled. UHFUS-based DOI and TT measurements were found to positively correlate with histology (p &lt, 0.05), although UHFUS provided a slight overestimation of DOI. No differences were found in terms of echogenicity or vascularization depending on the site of the lesion. According to these preliminary results, UHFUS could support the preoperative assessment of TT and DOI, potentially enhancing the clinical evaluation of OSCC.

Objective At our institution, we adopted routinely ultrasound guided approach for all percutaneous procedures. The objective of this study was to describe the predictors of access site failures (ASFs) in patients undergoing percutaneous aorto iliac revascularization and to also evaluate whether other factors such as time period or different vascular devices may influence outcomes in terms of ASFs. Methods We reviewed all consecutive percutaneous revascularizations performed for aortoiliac occlusion or stenosis at our institution from 2011 to 2020. All procedure were performed using an ultrasound (US) guided common femoral access. The primary outcome was ASFs, defined as bleeding or groin hematomas that required transfusions; pseduoaneurysm (diagnosed by US); retroperitoneal hematoma; artery laceration or ruptured (diagnosed intraoperatively); and thrombosis. Multivariable logistic regression was used to determine predictors of ASFs. Results A total of 502 femoral arteries were accessed under DUS guidance with no failure in sheath placement. Technical success was achieved in 498 of 502 procedures (99.2%). ASFs occurred in 21 patients (7%); but year of procedure appear to be associated with an excess of ASFs as rates were different between the first and second period of the study (10.9% vs 4.8%, P = .04). Results of multivariable logistic regression model indicated that independent predictors of ASFs were common femoral artery (CFA) calcification peripheral artery calcium scoring system (PACCS) grade (odds ratio [OR], 8.7; 95% confidence interval [CI], 5.5-13.7), and CFA diameter (OR, 0.46; 95% CI, 0.25-0.85). Compared to patients with successful percutaneous access, ASFs resulted in longer post-op lengths of stay (P = Conclusion Percutaneous US guided access can be safely performed in patients undergoing endovascular procedures for aorto iliac revascularization with TASC C and D lesions. CFA calcification PACCS grade greater than 3 and smaller femoral vessel diameter are independent risk factors for ASFs.

A 78-year-old woman presented with type IIIC and IIID endoleaks after endovascular treatment for a thoracoabdominal aortic aneurysm. Mating between the ruptured segments of superior mesenteric artery stent graft was performed. After failed attempts at relining the right renal artery stent graft, a hybrid approach was used to connect the side branch to the target vessel: a stent graft was deployed into the side branch of the main graft and it was temporarily occluded with a balloon. After opening the sac, a stent graft was deployed into the right renal artery and the two stent grafts were connected with a running suture. Follow-up examination performed 1 month postoperatively by computed tomography imaging confirmed the effectiveness of this treatment. Key Words: Thoracoabdominal, Hybrid technique, Multibranched graft, BEVAR

AIM An acute phase response is induced after non-surgical periodontal treatment (SRP). The main aim of this study was to compare acute phase (24-hr) and medium-term (3-months) inflammation and clinical outcomes after SRP with or without application of enamel matrix derivative (EMD) in sites with probing pocket depth (PPD) ≥ 6 mm. METHODS Thirty-eight periodontitis-affected subjects were randomized to SRP or SRP + EMD. Periodontal parameters were recorded at baseline and 3 months. Serum samples were collected at baseline, 1 and 90 days after treatment. RESULTS Both treatments triggered an intense acute inflammation on day 1, which regressed to baseline values at 3 months. D-dimer and cystatin C levels did not show sharp increases in SRP + EMD group 24 hr after treatment, compared to SRP. Significant difference between groups was observed for D-dimer (p

Purpose: To report preliminary outcomes of Viabahn Balloon-Expandable Endoprosthesis (VBX) stent-graft as bridging stent for renal arteries in fenestrated endovascular aneurysm repair (FEVAR). Materials and Methods: Between 2018 and 2019, patients undergoing FEVAR at 3 referral Italian university hospitals were prospectively collected. During the study period, VBX was the first-line choice as bridging stent for renal arteries. Procedural and anatomical data were analyzed, including renal artery (RA) configuration. A dedicated software (3Mensio, Vascular Imaging, Bilthoeven, The Netherlands) was used and RA anatomy classified as follow: upward-oriented in case of any angle >30° above the horizontal or transverse axis perpendicular to the aortic axis, downward-oriented if there was an angle >30° measured below the transverse axis and downward + upward in case of an angle 90°. Primary endpoints were technical success, defined as complete deployment of the fenestrated endograft without target vessel (TV) loss, limb stenosis or occlusion and type I or III endoleak, and freedom from target artery instability (TAI), defined by target vessel-related death, occlusion, rupture or reintervention for stenosis, endoleak or disconnection. Secondary endpoints were target artery patency rate and freedom from reinterventions. Results: A total of 26 elective FEVAR for juxta/pararenal aneurysm (20), thoracoabdominal type II (3) and type IV (3) were included. Fifty-one RA were planned for revascularization. Of these, 32 were downward, 10 horizontal, 6 upward, 4 were downward + upward. Technical success was achieved in 88.5% (23/26) of patients and 94.2% (48/51) of the TVs. One occlusion (2.1%) occurred within 30 days in a patient with previous endovascular aortic repair and suprarenal fixation. During follow-up (median 10 months), there was 1 type IC endoleak after 6 months (2.1%) in a patient with upward plus downward arterial orientation. Freedom from TAI was 96.1% (CI = 0.89 to 1.04) at first month and 92.3% (CI = 0.82 to 1.03) at 6 months. No aneurysm-related mortality and renal insufficiency occurred during follow-up. Conclusion: The use of VBX as bridging stent of RA in FEVAR is safe and feasible. Previous EVAR and tortuosity of RA may be a challenging on target vessel fate.

Aim : To describe a bailout technique to advance and precisely deploy thoracic endograft in the ascending aorta in case of difficulty crossing the aortic arch. Case Report : A 73-year-old man presented with a large ruptured aneurysms in the descending aorta. During the TEVAR, stent-graft passage through the aortic arch was impossible due to the severe tortuosity of the aorta. The problem has been resolved using the sheath-anchoring rail guidewire (SARG) technique. Through an axillary access, a snare was used to capture the stiff wire from the femoral access. A sheath was advanced over the stiff wire to the ascending aorta and placed there. By exploiting the grip of the sheath on the stiff in the ascending aorta, it was possible to handle the tension, move the delivery system through the arch and carefully deploy the graft. Conclusions : The SARG is a simple and quick learning technique which can be useful for Physicians dealing with complex aortic arch anatomy.

Background Concern exists about durability of stent grafts used to bridge aortic grafts to visceral and renal arteries during fenestrated and branched endovascular aneurysm repair (F/B-EVAR). There are no guidelines regarding the ideal technique for joining target vessels (TVs). Methods We systematically reviewed data published from 2014 to 2019 using PRISMA guidelines and PICO models. Keywords were searched in MEDLINE, EMBASE, and Cochrane Library. All articles were screened by two authors (a third author in case of discrepancies). Only original articles regarding F/B-EVAR in complex aortic aneurysm, reporting the number and type of TVs mated, the onset of bridging stent complications, and reinterventions on TVs were included. Analysis included quality assessment scoring, types of stent grafts, and complications related to bridging stents. Results 19 studies were included with 2,796 patients and 9556 TV; 4,797 renal arteries (50.2%), 4,174 visceral arteries (43.6%), and undefined TV (n = 585; 6.1%) were bridged. Balloon-expandable stent-grafts (B-EXP) were used in 40.9% and self-expandable (S-EXP) in 22.7% and undefined stents in 36.3%. The included studies had quality assessment scores ranging between 11/15 and 15/15, with high grade of accordance on reporting general results, but a low grade of accordance on reporting detailed data. Despite study heterogeneity, high-volume analysis confirmed a higher rate of complication in renal arteries than visceral arteries, 6% (95% CI 4–8) vs. 2% (95% CI 1–3), respectively. The rate of reinterventions was similar, 3% (95% CI 2–4) and 2% (95% CI 1–3). S-EXP versus B-EXP stent complication was 4% (95% CI 2–7) vs. 3% (95% CI 2–5), respectively. Conclusions This systematic review underlines the low grade of accordance in reporting detailed data of bridging stents in F/B-EVAR. Renal TVs were more prone to complications, with an equivalent reintervention rate to visceral TVs. As to B-EVAR, the choice of B-EXP over S-EXP is still uncertain.

Primary oral mucosal melanoma (OMM) is a rare neoplasm accounting for the 0.2% to 0.8% of all melanomas. The aim of the present manuscript is (1) to describe 2 cases of primary OMM treated at our department, and (2) to perform a systematic literature review on primary OMM occurrence and treatment.Two cases of primary OMM were described. A systematic review is presented in order to assess the treatment options, recurrence, metastasis development, and survival rate of primary OMM.Two patients were referred for the development of a lesion of the hard palate and the maxillary gingival mucosa, respectively. An incisional biopsy was performed in both patients, followed by extensive surgical resection after a thorough consideration of patient history and systemic involvement. The literature search retrieved 447 primary OMM cases. In the 30% of cases, distant metastases were already present at the time of diagnosis. The management of primary OMM most frequently involved surgical treatment and adjuvant radiotherapy.Primary OMM still represents a challenge for the clinician, as the diagnosis is often performed when metastases have already developed. The prognosis is generally poor, thus highlighting the need for further investigations to improve early diagnosis.

Purpose To evaluate the efficacy of endovascular repair of popliteal artery aneurysms (PAAs) with a wire-interwoven nitinol stent. Materials and Methods This is a prospective, descriptive, and analytical study. From January 2016 to December 2018, 28 consecutive patients (29 lower limbs) were treated for a PAA with the deployment of the Supera stent (Abbott Vascular, Illinois). Twenty-three (79.3%) PAAs were asymptomatic; 6 (20.7%) presented with symptoms. The mean diameter and length of the aneurysm were 26.8 mm (20–40 mm) and 47.1 mm (23–145 mm) respectively. The primary endpoint was the prevention of embolic symptoms. The secondary endpoints were aneurysm exclusion, aneurysm diameter decrease, freedom from reintervention, and preservation of preoperative runoff vessels. Results Technical success was 100%, with a median of 2.4 run-off vessels at completion angiography, without any loss of run-off vessels. A double Supera stent was deployed in 10 cases. At completion angiography, a median of 2.4 runoff vessels were present, without any loss of runoff vessels. The mean follow-up time was 24.3 (12–35) months. Primary endpoints were reached in 100% of the cases and vessels run off was preserved in all cases. In 2 PAAs, complete sac thrombosis was witnessed at 6-month follow-up, while at 12-month follow-up, it was seen in 10 of 29 (34.4%) limbs. In all the other cases the diameter of the aneurysm remained stable, with a freedom from sac enlargement of 100%. No fractures or stent thromboses were detected. Conclusions For endovascular repair of PAAs, the use of a thick interwoven-wire stent, that could work like a multilayer flow modulator showed encouraging mid-term results with no cases of stent fracture, occlusion or aneurysm increase.

BACKGROUND: COVID-19 outbreak had an extremely relevant impact on dental activity. Since the beginning of the pandemic, a previously unseen change in terms of procedures, organization of patient flow, and personal protective equipment (PPE) employed led to a reorganization of all the aspects of patient management. The aim of the present study was to report and compare current dental activity with pre-COVID era. METHODS: Data on the dental activity in the period 9th March - 9th September 2020 were retrieved and compared with the same period of the previous year. The differences with pre-COVID era in terms of patient schedule and PPE were evaluated using Student t-test for independent data. Significance was set at p

OBJECTIVE To assess the prevalence and severity of periodontitis (P) among Italian patients affected by rheumatoid arthritis (RA). MATERIALS AND METHODS A full-mouth periodontal examination and a rheumatologic examination were performed. RA disease activity was scored using the DAS28. Serum analyses investigated levels of rheumatoid factor, anti-citrullinated protein antibodies (ACPAs), C-reactive protein, erythrocyte sedimentation rate and fibrinogen. Information concerning smoking, body mass index and RA medical therapy was collected. Data were analysed by Student's t test, chi-square test, binary logistic regression and Spearman's rank. RESULTS This cross-sectional study included 120 subjects, 77 had both diseases while 43 only had RA. The number of teeth present was statistically lower in the RA-P compared to the RA group (p

Background Almost 38% of all patients with end-stage chronic kidney disease (CKD) have peripheral arterial disease of the lower limbs that can lead to chronic limb threatening ischemia (CLTI). The aim of this study was to assess the impact of several factors to conduct a stratification of the amputation risk in CKD patients with CLTI receiving endovascular revascularization. Methods Observational, retrospective, single-center study of patients treated from 2010 to 2016. The primary endpoint was the major amputation. The study included adult CKD dialysis patients affected by CLTI (rest pain and/or trophic lesions) with indication to endovascular revascularization and excluded for open repair. Results A total of 82 patients were considered (58 men [70.7%], 24 women [29.3%] mean age 70.4 ±15.0 years). The number of major amputations was 28 (34.1%). The arterial lesion severity (TASC II-classification) and the trophic lesions extension (WIfI classification) were significantly associated with major amputation (OR and 95%CI, 1.20 [1.07-1.34], p= .001; 2.65 [1.49-4.72], p= 0.001; respectively). Based on the abovementioned characteristics, a prognostic score was proposed to predict the major amputation risk. A score ≥23 was associated with a 67.6% probability of amputation in the following 12 months. Conclusions The CLTI revascularization is associated with poor outcomes in CKD patients. The present clinical score provided a pragmatic tool to calculate the major amputation risk. An elevated score could facilitate the decision-making process in order to perform an endovascular treatment vs conservative approach.

Purpose: To evaluate intravascular ultrasound (IVUS) safety and efficacy to detect visceral stenting issues during complex endovascular aneurysm repair through branched and fenestrated repair (B-FEVAR). Materials and Methods: A single-center retrospective analysis of 33 bridging stents assessed intraoperatively using IVUS between January and September 2020 was performed. Ten aortic aneurysm patients [7 thoracoabdominal / 1 pararenal / 2 juxtarenal; 3 females; mean age 73 years [range 70–77 years]) were included. Eight BEVAR (5 standard; 2 custom-made) and 2 FEVAR (custom-made) were performed. The study assessed the safety and efficacy of IVUS utilization to detect immediate branch instability after visceral stenting in the case of B-FEVAR. The primary safety endpoint was defined as the absence of IVUS-related adverse events. The primary efficacy endpoint was defined as the composite of technical success of the IVUS-assessment in each target visceral vessels (TVVs), the rate of IVUS-findings divided as prompting additional maneuvers or not, and the incidence of postoperative computed tomography angiography findings compared with intraoperative assessment. Results: There were no IVUS-related adverse events. The technical success of the IVUS-assessment was achieved in all TVVs. No technical issues compromised the evaluation of the intended vessel. Among the 7 findings identified by IVUS, 3 were suspected at the angiography. In all, 57% (4/7) had normal final angiography. IVUS was able to detect a 12% (4/33) intraoperative branch instability not identified/suspected at the completion angiography. The IVUS assessment led to an immediate revision in 5 (15%) vessels. A total of 57% (4/7) of the issues were detected in patients undergoing primary BEVAR. The remaining 43% (3/7) was detected in patients undergoing secondary intervention for branch instability. Conclusion: IVUS was safe as an adjunctive imaging technique to assess completion after B-FEVAR. It demonstrated efficacy in the detection of intraoperative issues missed by angiography. Further investigations are required to validate these promising results.

AIM To investigate the effect of rehabilitation in fully/partially edentulous patients with stage IV periodontitis on oral-health-related quality of life (OHRQoL) and systemic health. MATERIALS AND METHODS A systematic electronic and manual search was conducted. Three authors independently reviewed, selected, and extracted the data. Outcomes were OHRQoL (Oral Health Impact Profile 14 [OHIP-14] and OHIP-49, General Oral Health Assessment Index [GOHAI], visual analogue scale, symptoms registration) and systemic health-related outcomes (incidence and prevalence of systemic diseases, values of systemic disease indicators). Qualitative data were synthesized for OHRQoL and systemic health-related outcomes. Meta-analysis was conducted on available quantitative data. RESULTS The search identified 59 articles (6724 subjects in total). OHRQoL improved across all the studies, irrespective of the number of missing teeth, their location, or treatment modality. Meta-analysis showed significant improvement of OHIP-49 (36.86, p

Objectives During the months of March and April 2020, Italy saw an exponential outbreak of COVID‐19 epidemic. Dental practitioners were particularly limited in their routine activity, and the sole performance of urgent treatments was strongly encouraged during the peak of the epidemic. A survey among dental professionals was performed between 6th‐13th of April, in order to evaluate the status of dental practice during COVID‐19 in Italy. Materials and Methods An online anonymous questionnaire was administered to retrieve data on the dental procedures performed, the preventive measures adopted, and the predictions on the future changes in dentistry following the pandemic. Results The survey was completed by 3,254 respondents and, according to the results obtained, dental activity was reduced by the 95% and limited to urgent treatments. The majority of the surveyed dentists employed additional personal protective equipment compared to normal routine, although in a non‐negligible number of cases difficulty in retrieving the necessary equipment was reported. Conclusions The survey provided a snapshot of dental activity during the SARS‐CoV‐2 outbreak. Overall, following the peak of the epidemic, it is probable that dental activities will undergo some relevant changes prior to fully restart.

Bellosta et al1 recently demonstrated a significantly higher incidence of acute limb ischemia (ALI) in COVID-19 patients. In addition, an increased failure rate after revascularization occurred. The colleagues must be complemented for their clinical and scientific com- mitments. The increased thromboembolic complica- tions in COVID-19 patients have been reported even in those receiving anticoagulant therapy and in nonathero- sclerotic patients.1-3 More than 27,000 COVID-19 cases were registered in our region (Emilia-Romagna). Our unit represents the unique vascular surgery service in the province of Modena. As a tertiary COVID center, we did not observe ALI in such patients. It must be taken into account that Bellosta et al1 provide care in an Italian region with a higher incidence of COVID-19 (Lombardia). However, this difference of incidence in northern Italy remains unclear. We observed two COVID-19 patients with concomitant pulmonary embolism (PE) and aortic floating thrombus (AFT; Fig). They were asymptomatic for peripheral embolism and without a source for the PE. Because of the PE, anticoagulant therapy and low- dose antiplatelet therapy were initiated. A significant reduction of the AFT was observed with resolution of the PE in both patients. The AFT is a rare but serious clin- ical condition able to cause dramatic peripheral embo- lism.4 Aortic stent implantation, abnormal coagulation function, and aortic diseases were reported as predictors of AFT.4 Medical therapy was proposed as the treatment of choice in asymptomatic AFT patients.4 Following the plethora of procoagulant modifications described in COVID-19 patients and the above-mentioned trends to intrastent thrombus relapse, we preferred to avoid inva- sive procedures.4,5 Indeed, the AFT may be a more common source of ALI in COVID-19. The preoperative workup reported by Bellosta et al1 did not include thoracic computed tomography (CT) angiog- raphy. COVID-19 patients are usually diagnosed by means of CT scans, and our observations were possible thanks to the use of contrast medium. Finally, thoracoabdominal CT angiography should be considered a routine evaluation in COVID-19 patients presenting with embolic complications. Clearly, further investigations are required: the throm- botic mechanism; the type, dose, and duration of the anti- coagulant therapy; and the indications for and timing of surgical management of thrombus and emboli.1-3,5

Objectives: The aim was to report indications, technical aspects, and outcomes of a multicentre experience of late open conversions (LOCs) after endovascular abdominal aneurysm repair (EVAR), in order to identify risk factors which may influence early morbidity and mortality rates, and long term survival. Methods: Ten vascular centres retrospectively reviewed all patients requiring LOC (≥30 days from initial EVAR, undergoing total or partial endograft explantation) from 1996 to 2017. Baseline characteristics, endograft data, indications, procedural details, post-operative outcomes, and follow up data were reviewed and analysed. Results: Included patients totalled 232 (90.1% males, mean age 74.3 ± 7.9 years). The number of LOC per year significantly increased during the study period, reaching 22 in 2017 (correlation r = 0.867, p

Background The aim of this study is to compare early and late results of an expanded polytetrafluoroethylene (ePTFE—Gore TAG®, group A) mesh structured endograft versus a Dacron one (Relay Plus® Bolton, group B) in thoracic endovascular aneurysm repair (TEVAR). Methods A prospective database was used to extract information from anonymous patients who underwent TEVAR for descending thoracic aortic aneurysms (DTAAs) between February 2005 and February 2019 at 3 referral university hospitals. Cases treated by means of ePTFE endograft (Gore TAG, group A) and Dacron graft (Relay Plus Bolton, group B) in elective and urgent settings were included. Early and late outcomes were compared. Results A total of 129 consecutive patients were included (115 men and 14 women). ePTFE—Gore TAG® and Dacron—Relay Plus® Bolton were used in 56 (43.4%) and 73 (56.5%) patients, respectively. Preoperative characteristics of patients were similar. Technical success was 100%. Urgent procedures were 22.4%. Mean aortic coverage and partial debranching were 217.5 ± 91.3 and 37.2%, respectively. Early mortality and spinal cord ischemia (SCI) were 8.5% and 2.3%, respectively, without differences between the 2 groups. Early reintervention was required in 5.4% (group A) and 11% (group B), P = 0.29. Median follow-up was 32 months (interquartile range 12–55 months, range 1–156 months), similar between the 2 groups. Type I endoleak (EL), type II EL, and type III EL were observed in 16.3%, 10.9%, and 3.1% of cases, respectively, without significant differences between the groups. The rate of sac shrinkage was 28.6% in group A vs. 39.7% in group B (P = 0.19). Freedom from reintervention in group A versus group B at 6, 12, 24, and 36 months was 94.0% vs. 97.1%, 94.0% vs. 95.5%, 90.8% vs. 86.9%, and 81.1% vs. 80.4%, respectively (log-rank 0.35, Breslow 0.54). Rate of survival at 6, 12, 24, and 36 months was 96.0% vs. 94.2%, 89.3% vs. 86.8%, 76.5% vs. 77.5%, and 63.3% vs. 64.2%, respectively (log-rank 0.30, Breslow 0.57). Conclusions ePTFE—Gore TAG and Dacron—Relay Plus Bolton in DTAA presented similar early and late results in terms of mortality, SCI, EL, and TEVAR-related reinterventions. Effectiveness of TEVAR procedure was confirmed by the high rate of sac shrinkage and it was not influenced by endograft fabric.

Objectives The aim of the present study is to report a case series of patients with peri-implant medication-related osteonecrosis of the jaw (MRONJ), in particular describing the onset of the condition and surgical treatment outcome. Material and methods Fifteen consecutive patients with clinical diagnosis of peri-implant MRONJ were retrospectively included in the study. The sample was stratified on the base of oral, pharmacological, and general health variables. The number of affected implants was recorded in all patients, and MRONJ staging applied. Surgical treatment was performed with a standardized operative protocol, involving implant removal, sequestrectomy, debridement of soft tissue, and bone curettage. Follow-up evaluating surgical outcome was performed at twelve months after surgery. Results in our study sample, patients were almost equally distributed in terms of underlying diseases in osteoporotic and oncologic patients. All MRONJ lesions were symptomatic, and in 6 patients bone exposure was detected. 40 implants in total were evaluated, with MRONJ being present around 29 implants. 12 patients were diagnosed with Stage III MRONJ, and 3 patients with Stage II MRONJ. Surgical treatment leads to complete healing in 86.7% of cases, with 100% success for maxillary MRONJ. Conclusions Surgical treatment seems to have a positive impact on MRONJ treatment also in cases of peri-implant involvement. However, monitoring and prevention are fundamental in patients under pharmacological treatment with anti-resorptive/antiangiogenic drugs, as peri-implant MRONJ can develop also in absence of specific traumatic events.

Objective To evaluate the effect of periodontitis (PD) on glucoregulatory hormones in obesity, never explored so far, a cross-sectional study was conducted in 110 severely obese, non-diabetic individuals. Methods We collected clinical periodontal parameters, including probing pocket depth (PPD), bleeding on probing (BOP), clinical attachment level (CAL). Insulin, glucagon, GLP-1 and GIP were measured after 3 days of standardized diet. Results Forty-seven subjects had periodontitis (PD+) and 63 did not (PD−). PD+ showed 30.3% of gingival sites with PPD > 4 mm, 55.2% of BOP sites and a mean CAL loss of 4.1 mm. Compared with PD−, PD+ had higher glucagon (26.60 [25.22] vs 3.93 [7.50] ng/l, p

Objectives To determine the efficacy of 4 different oral hygiene regimens involving adjunctive interdental cleaning devices in unsupervised young subjects with intact interdental papilla. Material and methods Sixty periodontally healthy subjects were randomly allocated to 4 groups following different oral hygiene regimens (T-7): use of manual toothbrush alone; manual toothbrush plus dental floss; manual toothbrush plus interdental brushes; and manual toothbrush plus rubber interdental picks. Oral hygiene instructions (OHI) were given. One week after (T0), professional supragingival scaling and polishing was performed, and subjects were then reseen every 2 weeks (T14 and T28). At T-7, T0, T14 and T28, full-mouth plaque score (FMPS), full-mouth bleeding score (FMBS) and angulated bleeding index (AngBI) were taken. Results During the first week (T-7/T0 unclean phase), FMPS decreased significantly in all groups except the group using dental floss. At T28, a significant decrease in FMPS (P

BaCKground: To assess the long-term safety and effectiveness of endovascular aneurysm repair (evar) treatment with unibody endograft deployed on aortic bifurcation (anatomical fixation). MeThods: a retrospective, observational, single-center study of patients treated from 1999 to 2002 with unibody bifurcated endograft. follow-up protocol required clinical and doppler-ultrasound at 1 and 6 months and annually thereafter, computed tomography angiography at 1-, 6- and 12-months and then every year. Primary endpoints included technical and treatment success, survival and freedom from late evar failure; secondary endpoints were freedom from late open conversion (loC), freedom from late re-interventions and endoleaks. resulTs: seventy-three patients, mean age of 73±6 years were enrolled. Median follow-up was 6±0.5 years. Technical success was 98.6% (n.=71/73; causes of failure: 1 open conversion and 1 type ib endoleak). a treatment success of 96% (n.=69/72) was recorded due to endoleaks (n.=2; 1 type ia and 1 type ib) and limb occlusion (n.=1). survival at 1, 5, 10, 15 and 18 years was 90%, 58%, 40%, 32% and 23% respectively. one aneurysm-related death for infection of the endograft was registered. evar failure was 14% (n.=10/71). Three loC were recorded and freedom from reinterventions at 1, 5, 10 and 18 years was 99%, 91%, 86% and 86%. fourteen endoleaks were recorded: ia (n.=6; 42.8%), ia+ib (n.=1; 7.1%), ib (n.=2; 14.2%) and ii (n.=5; 35.6%). four endoleaks were observed, 9 endovascular correction and 1 loC were required. endoleaks free survival of 90% at 1-year and 75% at the end of the study. aneurysm sac shrinkage was observed in 79% (n.=56/71). CONCLUSIONS: This small, retrospective cohort of anatomically fixed EVAR demonstrated long-term safety and effectiveness. The design of the unibody graft did not substantially change and newer generation should guarantee the same performance.

AIM The aim of this study was to compare surgical treatment of periodontal intra-bony defects (IBD) with or without the adjunct of enamel matrix derivative (EMD) in terms of acute-phase responses in healthy patients. METHODS Thirty-eight periodontitis-affected subjects, one IDB each, were randomized to minimally invasive periodontal surgery (MIS) with or without EMD. Periodontal parameters were recorded at baseline and 6-months. Blood samples were collected at baseline, 1, 7 and 180 days after treatment. RESULTS At 24 hr, the group treated MIS with EMD showed lower values of C-reactive protein (CRP; p

Background The diabetic foot ulcer (DFU) is one of the most prevalent complications of diabetes mellitus and often develops severe effects that can lead to amputation. A non-healing “minor” amputation often precedes a major amputation resulting in a negative impact on the function and quality of life of the patients. Stem cell-based therapies have emerged as a promising option to improve healing, and the adipose tissue is an abundant and easy to access source. The injection of autologous micro-fragmented adipose tissue at the amputation stump of a diabetic population undergoing a lower limb minor amputation was evaluated and compared with the standard care. Methods In this randomized controlled trial with two arms (parallel assignment) and no masking, 114 patients undergoing a lower limb minor amputation were randomized to standard of care or to micro-fragmented adipose tissue injection prepared using a minimal manipulation technique (Lipogems®) in a closed system. Clinical outcomes were determined monthly up to 6 months. Primary endpoint of the study was the evaluation of the healing rate and time after the minor amputation. Secondary endpoints included the assessment of safety, feasibility, technical success, relapse rate, skin tropism, and intensity of pain. Results At 6 months, 80% of the micro-fragmented adipose tissue-treated feet healed and 20% failed as compared with the control group where 46% healed and 54% failed (p = 0.0064). No treatment-related adverse events nor relapses were documented, and technical success was achieved in all cases. The skin tropism was improved in the treatment group, and the pain scale did not differ between the two groups. Conclusion The results of this randomized controlled trial suggest that the local injection of autologous micro-fragmented adipose tissue is a safe and valid therapeutic option able to improve healing rate following minor amputations of irreversible DFU. The technique overcomes several stem cell therapy-related criticisms and its potential in wound care should be better evaluated and the therapeutic indications could be expanded. Trial registration ClinicalTrials.gov number: NCT03276312. Date of registration: September 8, 2017 (retrospectively registered).

Over 20 years from the first endovascular aortic repair, endoleaks still represent a common problem, even with newer endograft generation. Numerous procedures can be adopted to manage these complications; relining of the endoprosthesis is a rational technique to treat type III and IV endoleaks. The absence of dedicated materials for these procedures forces the vascular surgeon to perform complex hybrid or endovascular interventions. In this case report, we aimed to evaluate our relining experience using the Nellix device in 5 consecutive cases.

Endovascular treatment nowadays represents a valuable option in the treatment of ruptured abdominal aortic aneurysms (rAAAs). The aim of this study is to evaluate a 15-year, single-center experience with endovascular treatment of rAAAs and the role of the type of fixation in outcome.Retrospective analysis of all consecutive hemodynamically stable and unstable patients with a diagnosed rAAA treated at this hospital with an endovascular procedure between December 1999 and January 2015 was conducted. Patients with symptomatic aneurysms and impending ruptures were excluded. Predictive factors of immediate and overall major complications and survival were investigated. Study end points included technical and clinical success, mortality, and major adverse events.This study included 142 patients. Technical success was 97.1% within 30 days, 60 major adverse events were reported in 43 patients (30.3%), including 40 deaths (28.2%). Clinical success at 30 days was 59.9%. Predictive factors of 30-day mortality were chronic renal disease (odds ratio [OR] 3.44, P = 0.006), chronic obstructive pulmonary disease (OR 2.42, P = 0.032), hemodynamic instability at presentation (OR 4.57, P = 0.001), and the use of an aortic balloon (OR 23.4, P 0.001). The use of local anesthesia (OR 0.38, P = 0.017) had a protective influence. One-year survival was 52%. At a median follow-up of 44 months (range 0.5-152), overall survival was 39% (95% CI 30-48), with a median overall survival of 13 month (95% CI 6-36). Five-year survival was 23%. Predictive factors of long-term mortality were advanced age (85 years) (hazard ratio [HR] 2.0, P = 0.002), hemodynamic instability at admission (HR 1.90, P = 0.005), and the use of an aortic balloon (HR 4.56, P 0.001). The implantation of an anatomically fixated (AFIX) device was found to be protective against mortality (OR 0.41, P = 0.011).In this series, satisfactory rates of complications and survival were observed after endovascular repair of rAAAs. In addition to the well-known predictors of outcome, the type of fixation also seems to play a significant role, and the AFIX device was associated with improved longer term survival when its use was deemed feasible.

BACKGROUND: To assess immediate and midterm outcomes of hemodynamically-unstable patients with ruptured abdominal aortic aneurysm (rAAA) treated with the Nellix endovascular sealing system (EVAS). METHODS: From June 2014 to June 2017, 21 hemodynamically-unstable rAAA patients with challenging anatomies were treated with EVAS. The mean AAA diameter and neck length measured 73}15 mm and 14}10 mm, respectively. All the patients presented an advance trauma life support (ATLS) hemorrhage class.1 confirming a compromised hemodynamic status. Primary endpoints include technical success, treatment success, primary safety and 30-day survival. Secondary endpoints include re-intervention rate and time free-from-reintervention. RESULTS: Technical success was achieved in 95% (N.=20/21); one patient was converted intraoperatively to open surgery due to ongoing hemorrhage. Seven re-interventions were performed within 30-days and one during the follow-up; treatment success rate of 67% and re-intervention rate of 33%. Early endoleaks were diagnosed in 5 patients (24%). Primary safety was 52%. After a mean follow-up of 11}10 months, survival rates were 81%, 62% and 57% at 1, 6 and 12 months, respectively. Time free-from-reintervention was 15}11 months. CONCLUSIONS: Emergency-EVAS (eEVAS) appeared feasible and useful, especially in hemodynamically-unstable patients with challenging anatomies. There are some limitations in this cohort study and larger, prospective and comparative studies are required to confirm eEVAS as part of an emergency treatment protocol for rAAA.

Background: To assess the nutraceutical effects of twice/daily intake of kiwifruit on periodontal parameters and systemic health before and after initial periodontal treatment (IPT). Methods: At baseline, participants were randomly assigned to test and control group, and either consumed two kiwifruits/day for 5 months or no kiwifruit. In the first 2 months, no periodontal treatment was delivered (2 M). Subsequently, a session of full-mouth IPT within 24 hours was performed. Participants were then re-assessed after 3 months (5 M). Blood samples, evaluating systemic biomarkers and vital signs, were also collected atbaseline, 2 M, and 5 M. Results: Groups were balanced at baseline. At 2 M no within-groups differences could be detected for any parameter but the bleeding score, which decreased significantly in the kiwifruit group by 6.67% ± 11.90% (P < 0.01). Comparison of test and control group showed that 2 months of kiwifruit consumption resulted in significant lower values of bleeding, plaque, and attachment loss. After IPT both groups demonstrated substantial significant clinical benefits however the control group showed significant greater reductions of bleeding, plaque and attachment loss than the test group. Systemic biomarkers and vital signs did not show clinically relevant differences between test and control group. Conclusions: Kiwifruit consumption reduces gingival inflammation despite the lack of any periodontal instrumentation or patient's behavioral changes. No adjunctive effect to periodontal treatment of dietary intake of kiwifruit was noted. (NCT NCT03084484).

The purpose of the study was to evaluate the efficacy of conservative surgical treatment of medication related osteonecrosis of the jaw (MRONJ) in patients affected by osteoporosis and exposed to oral bisphosphonates (BPs). Subjects diagnosed with MRONJ and osteoporosis under oral BPs that had undergone conservative surgery and had at least 24 months follow-up were included. All patients received medical-antibiotic therapy and then underwent conservative surgical treatment consisting of sequestrectomy, soft tissue debridement and bone curettage with limited or no extension. A total of 53 patients, mean age of 71.9 ± 10.2 years (range 41-87), were enrolled. Two years after conservative surgical therapy 45 patients (91.8%) showed complete healing. The presence of rheumatoid arthritis (p = 0.003) and a more severe initial MRONJ stage (p = 0.023) were associated with a negative surgical outcome while the presence of bone sequestrum was strongly associated with a positive outcome (p = 0.036). Conservative surgical treatment of MRONJ lesions in patients affected by osteoporosis and receiving only oral BPs may represent a valid therapeutic approach determining a high number of complete healing cases. Conservative surgery should be encouraged at early MRONJ stages and after medical therapy failure.

To compare nephrotoxic and radiation exposure during elective endovascular aneurysm repair (EVAR) of abdominal aortic aneurysms in a selected patient cohort treated with 2 different infrarenal endograft types: the unibody and modular.Procedural data were retrospectively collected in a single center, case-controlled study. From January 2010 to January 2012, patients treated with elective EVAR were analyzed. Patients treated for thoracoabdominal aneurysms, aortic dissection, aortoiliac aneurysms, and pseudoaneurysms were excluded. The remaining subjects were divided according to the endograft type: group A treated with a unibody endograft type (60 patients) and group B (57 patients) treated with a modular endograft type. Outcome measures included total procedural time, total fluoroscopy time, and volume of contrast medium.All end points for group A and B were statistically significantly different; median surgical procedure duration was 75 vs. 105 min (P 0.0001), median volume of iodine contrast injected was 85 vs. 170 mL (P 0.0001), and median fluoroscopy time was 350 vs. 780 sec (P 0.0001).The overall EVAR procedural duration, fluoroscopy time, and volume of contrast medium infusion were significantly reduced in the group treated with the unibody endografts. These results seem to suggest that the unibody endograft may reduce patient risk of nephrotoxic action of the contrast medium, especially important in patients with existing renal insufficiency, and may reduce ionizing radiation exposure for both the patients and operators.

Objectives To systematically review the performance of access flap (OFD) in the treatment of class II furcation defects (FD). Methods RCTs evaluating surgical treatment of class II FD with OFD, minimum 6 months follow-up were identified. Screening, data extraction, and quality assessment were conducted independently by three reviewers. The primary outcomes were tooth survival and change in the horizontal clinical attachment level (HCAL). Changes in vertical clinical attachment level (VCAL), reduction of pocket probing depth (PPD), recession increase (REC), horizontal (HBL), and vertical bone level (VBL) were also collected. Results The search identified 1571 studies out of which 11 articles met the inclusion criteria. Data analysis was performed on 199 patients and 251 FD. Tooth survival was seldom reported. Altogether with inflammatory amelioration, the weighted mean differences were for HCAL 0.96 mm [CI: (0.60, 1.32), p

Aim To update the available evidence on the impact of periodontitis on diabetes control, incidence and complications. Methods Observational studies on the effect of periodontitis on diabetes, published after 2012, were identified through electronic databases and hand-searched journals. Findings were summarized by evidence tables, using PRISMA statement. Quality of the included studies was evaluated through the Newcastle Ottawa scale. Results Healthy individuals with periodontitis exhibit a poor glycaemic control and a higher risk of developing diabetes. Individuals affected by diabetes show a deterioration of glycaemic control if also affected by periodontitis and significantly higher prevalence of diabetes-related complications. Limited evidence is available on gestational diabetes and type 1 diabetes. Conclusions Periodontitis has a significant impact on diabetes control, incidence and complications. Nevertheless, the heterogeneity and quality of the included publications suggest that caution should be exercised when interpreting the data and that there remains an important need for additional evidence.

BACKGROUND The aim of this study was to assess clinical and contemporary costs associated with elective endovascular repair of intact descending thoracic aortic aneurysms (DTAA) into the mid-term follow-up. METHODS A retrospective review of a prospectively maintained clinical database including 29 consecutive patients from July 2005 to December 2009 treated with elective endovascular repair (TEVAR) or TEVAR and surgical infrarenal repair (hybrid) of intact DTAA was performed. Mean age was 74.5 years old (±7.1). Primary clinical endpoints include mortality and major morbidity. Additionally a comprehensive economic appraisal of individual in-hospital and follow-up costs was executed. Economic endpoints include in-hospital and follow-up costs and patient discharge status. Elective endovascular and open repairs' clinical and economical outcomes in contemporary literature were assessed for comparison according to PRISMA standards. RESULTS Immediate mortality was 6.9% (1/24 TEVAR and 1/5 hybrid). Three respiratory complications were recorded (11%; 2 TEVAR, 1 hybrid). Renal and cardiac complication rates were 7.4% (1 TEVAR, 1 hybrid) and 3.7% (1 TEVAR) respectively. Routine discharge home was achieved for 85% of patients (95.7% TEVAR, 25% hybrid). Three endoleaks were treated throughout the follow-up (2 TEVAR, 1 hybrid; mean 30.4 mo, ±19.9) rendering an 11% (3/27) reintervention rate. Average immediate cost was €21,976.87 for elective endovascular repair and €33,783.21 for elective endovascular hybrid repair. Additional reintervention and routine follow-up costs augmented immediate costs by 12.4%. CONCLUSIONS This study supports satisfying immediate clinical outcomes for TEVAR and TEVAR+surgical infrarenal procedures. Although limited by a small population size and difficulties in economic comparisons, this study presents the real world social and economic cost scenario for both elective TEVAR and TEVAR hybrid treatment of DTAA of both the in-hospital and at mid term follow-up periods.

Third molar extraction is one of the most frequent interventions in dentistry. Nevertheless, there is scarce evidence on the host response of individuals with impacted or semi-impacted third molars and the possible effects of surgical removal. A case-control study of 40 patients was designed to evaluate 1) the differences in biomarkers of systemic inflammation, vascular function, and metabolism (high-sensitive C-reactive protein, lipids, fibrinogen, oxidative stress, and endothelial function analysis) and 2) the acute and short-term effects of surgical removal in patients with bilateral impacted or semi-impacted third molars compared to controls with no third molars. Patients undergoing third molar extraction exhibited greater levels of systemic inflammation, oxidative stress, and triglycerides than controls. Raised white blood cell counts as well as peaks of serum levels of C-reactive protein and fibrinogen were noticed in the first postoperative week. Three months after the extraction, all markers returned to baseline values. Malondialdehyde, an indicator of oxidative stress indicator, was significantly reduced after third molar removal. Semi-impacted or impacted third molars are associated with higher systemic inflammation, and their removal may represent a useful human model to study acute inflammation and determine beneficial systemic effects ( ClinicalTrials.gov NCT03048175).

Objective: The objective of this study was to assess immediate and midterm outcomes for urgent/emergent and elective patients with thoracoabdominal aortic aneurysms (TAAAs) treated with the first commercially available “off-the-shelf“ multibranched endograft for endovascular aneurysm repair, with a single-step or a staged surgical approach. Methods: A multicenter, nonrandomized, retrospective study was conducted of TAAA patients grouped by urgent/emergent and elective treatment with multibranched endograft for endovascular aneurysm repair at 13 Italian centers from November 2012 to August 2016. Urgent/emergent repair was classified as rupture in 16%, impending rupture in 9%, pain in 53%, or a maximum TAAA diameter ≥80 mm in 22%. Study end points were technical success, mortality, spinal cord ischemia, target visceral vessel (TVV) patency, and procedure-related reinterventions at 30 days and at follow-up. Results: Seventy-three patients (274 TVVs) were enrolled. Treatment was performed in elective (n = 41 [56%]) or urgent/emergent (n = 32 [44%]) settings, according to a single-step (n = 30 [41%]) or staged (n = 43 [59%]) approach. Technical success was 92%. Mortality within 30 days was 4% (n = 3 urgent/emergent patients) due to myocardial infarction. Spinal cord ischemia was recorded in two patients (3%; elective group). The primary patency of TVVs was 99% (three renal branch occlusions). Procedure-related reinterventions were required in five cases (7%). At least one adverse event from any cause ≤30 days was registered in 42% (n = 31). At a median follow-up of 18 months (range, 1-43 months), eight (11%) deaths (elective vs urgent/emergent, 2% vs 22%; P = .018), three (1%) cases of branch occlusion or stenosis, and five (7%) reinterventions were recorded. A survival of 88% (standard error [SE], 4%), 86% (SE, 4%), and 82% (SE, 5%) was evidenced at 12, 24, and 36 months, respectively. Urgent/emergent repair and female gender were identified as independent risk factors for all-cause mortality (P < .001 and P = .015, respectively), and the staged approach was identified as protective (P = .026). Freedom from reintervention was 86% (SE, 4%) and 83% (SE, 5%) at 12 and 24 months. Conclusions: The first off-the-shelf multibranched endograft seems safe in both urgent/emergent and elective settings. The staged surgical approach appears to positively influence overall survival. This unique device and its operators will usher in a new treatment paradigm for TAAA repair.

Objective To review the effectiveness of enamel matrix derivative (EMD) in the treatment of periodontal pockets of suprabony defects. Methods Randomized Clinical Trials comparing open flap debridement (OFD) versus EMD in periodontal suprabony defects were identified through electronic and manual search. Screening, data extraction and quality assessment were conducted. The primary outcome measures were tooth survival (TS) and clinical attachment level (CAL) gain. Pocket probing depth (PPD) reduction and recession (REC) increase were secondary outcome measures. Information concerning clinical and radiological bone gain was also collected. Results The search identified 1170 studies, three articles reporting on (99 subjects/358 teeth) met the inclusion criteria and were included. No tooth was lost during follow-up (8–12 months). The adjunctive mean benefit of EMD was: 1.2 mm for CAL gain [confidence interval (CI): (0.9, 1.4), p

We evaluated retrospectively the efficacy of local resection for patients who presented with bisphosphonate-related osteonecrosis of the jaw (BRONJ). We studied 120 subjects with who required local resection of 129 BRONJ lesions that had not responded to medical treatment. The primary outcomes were improvement of the clinical stage of BRONJ and resolution of disease, and the secondary outcome was the influence of the surgeon's experience on the healing of the lesions. Age, sex, underlying diseases, smoking, and coexisting conditions were recorded. Logistic regression analysis was used to isolate factors that could potentially affect the outcome. Most of the lesions (n=107, 84%) improved postoperatively, 20 showed no change, and one got worse. One patient died. Stratification indicated complete healing and total resolution of disease for all 26 stage I lesions, improvement for 67 of the 77 stage II lesions, and for 14 of the 25 stage III lesions. The disease resolved in 67 of the 69 stage II lesions, and 14 of the stage III cases. Logistic regression indicated that smoking and the stage of disease could affect the outcome. Analysis of the surgeons' learning curve showed that performance improved significantly over time. Complete healing after local resection increased from 40% to 80% over a period of eight years (p

Aim: To systematically review the literature and to determine the clinical performance of conservative surgery (CS) for the treatment of intrabony defects (ID). Methods: RCTs on ID treatment with 12 months of follow-up were identified through electronic databases and hand-searched journals. Primary outcomes were tooth survival, clinical attachment (CAL) gain, probing depth (PD) reduction and gingival recession increase (REC). Weighted means and forest plots were calculated for each outcome variable 12 months after surgery. Long-term stability was explored with RCTs of at least 24 months of follow-up. Subgroup analysis was performed according to the type of flap. Results: Twenty-seven trials reporting 647 subjects and 734 defects were identified. Twelve months after CS, tooth survival was 98% (IQ: 96.77-100), CAL gain 1.65 mm (95% CI: 1.37-1.94; p < 0.0001), PD reduction 2.80 mm (CI: 2.43-3.18; p < 0.0001) and REC increase 1.26 mm (CI: 0.94-1.49; p < 0.0001). Longer follow-up showed similar findings. CI of CAL gain were 1.44-3.52 for recently introduced papilla preservation flaps and 1.25-1.89 mm for access flaps. Conclusions: The treatment of intrabony defect with CS is associated with high tooth retention and improvement of periodontal clinical parameters. Clinical performance may vary according to the type of surgical flap used. © 2011 John Wiley & Sons A/S.
