Pharmacological Sedation in Paediatric Dentistry.

AIM: This research aims to explore and evaluate various sedation strategies used in paediatric dentistry, focusing on effectively and safely addressing dental anxiety to improve cooperation during dental treatment in paediatric patients. MATERIALS: To identify relevant studies for this systematic review, the Scopus, Web of Science and PubMed databases were used, combining the terms "sedation" with "pediatric dentistry" or "pedodontics" through the Boolean operators "AND" and "OR". Only literature published in English within the last ten years was included. The inclusion criteria were clinical studies, case reports and in vivo studies, while systematic reviews, meta-analyses and studies conducted on animals or in vitro were excluded. After eliminating duplicates, 544 articles were identified, of which 501 were excluded for not meeting the inclusion criteria. A further 27 articles were excluded for various reasons, including lack of retrieval, in vitro nature or being reviews. Finally, 16 articles were selected for inclusion in the review. CONCLUSION: These findings underscore the importance of pharmacological management in paediatric dental care, offering valuable insights into the selection and application of sedation techniques to mitigate dental anxiety and enhance patient outcomes.

Correlation between vegetarian diet and oral health: a systematic review.

OBJECTIVE: Nutrition plays a significant role in preserving the balance of the human body. Considering each person's particular characteristics, diet can directly and indirectly alter the body's immune response. The purpose of this study is to draw attention to the connection between a vegetarian diet and its impact on oral health. MATERIALS AND METHODS: To determine the connection between a vegetarian diet and dental health, a search of the literature was conducted on the PubMed, Scopus, and Web of Science databases. English language and a publication year between January 1, 2013, and March 1, 2023, were the inclusion criteria for the search. RESULTS: There were 167 articles in total that addressed the subject of interest, and 18 of them were chosen for qualitative analysis. CONCLUSIONS: This study suggests that a vegetarian diet may alter oral health, namely periodontal health, tooth erosion, and oral microbiome. Even if the data collected prevents the effect of a vegetarian diet on oral health from being confirmed, this study acts as a starting point for future, more focused research.

Autologous tooth for bone regeneration: dimensional examination of Tooth Transformer® granules.

OBJECTIVE: Since 1967, when the osteoinduction properties of autogenous demineralized dentin matrix were discovered, autologous tooth grafts have been advocated as a viable option to autologous or heterologous bone graft. Tooth graft materials may be extracted from the patient's whole tooth using a granulating device. The aim of this study was to examine the size of granules obtained by the Tooth Transformer (TT)® device, using a laser instrument with high precision. MATERIALS AND METHODS: The TT® device can obtain bone graft material in a short period from an extracted tooth. The resulting material can act as an osteoconductive scaffold, providing a mineral substrate during resorption, including platelet growth factors and morphogenetic proteins. Different studies have investigated the dimension and behavior of various graft material particles, since the size of the grafted particles may play a role in osteogenesis and bone regeneration. RESULTS: Different dimensions of granules are available: small (< 400 µm), medium (400 µm-1,000 µm) and large (1,000 µm-2,000 µm). From 4.03 µm to 100 µm the percentage of granules was 14.52 ± 1.93%. A larger part of the granules was up to 100 µm, while 85.47 ± 1.93% of the granules were from 100 µm to 1,000 µm. CONCLUSIONS: 85% of the granules produced were in accordance with the dimensions suggested in the literature.

Author Correction: Impact of sacubitril/valsartan on implantable defibrillator eligibility in heart failure: a real-world experience.

Correction to: European Review for Medical and Pharmacological Sciences 2021; 25 (18): 5690-5700-DOI: 10.26355/eurrev_202109_26788-PMID: 34604961, published online on 30 September 2021. After publication, the authors applied to change the first two lines of Table II as the second column results were erroneously shifted in the first column. In this way, the results were quite difficult to understand. There are amendments to this paper.

Impact of ablation index settings on pulmonary vein reconnection.

PURPOSE: Ablation index (AI) is a radiofrequency lesion quality marker. The AI value that allows effective and safe pulmonary vein isolation (PVI) is still debated. We evaluated the incidence of acute and late PV reconnection (PVR) with different AI settings and its predictors. METHODS: The Ablation Index Registry is a multicenter study that included patients with paroxysmal/persistent atrial fibrillation (AF) who underwent first-time ablation. Each operator performed the ablation using his preferred ablation catheter (ThermoCool® SmartTouch or Surround Flow) and AI setting (380 posterior-500 anterior and 330 posterior-450 anterior). We divided the study population into two groups according to the AI setting used: group 1 (330-450) and group 2 (380-500). Incidence of acute PVR was validated within 30 min after PVI, whereas the incidence of late PVR was evaluated at repeat procedure. RESULTS: Overall, 490 patients were divided into groups 1 (258) and 2 (232). There was no significant difference in the procedural time, fluoroscopy time, and rate of the first-pass PVI between the two study groups. Acute PVR was observed in 5.6% PVs. The rate of acute PVR was slightly higher in group 2 (64/943, 6.8%, PVs) than in group 1 (48/1045, 4.6% PVs, p = 0.04). Thirty patients (6%) underwent a repeat procedure and late PVR was observed in 57/116 (49%) PVs (number of reconnected PV per patient of 1.9 ± 1.6). A similar rate of late PVR was found in the two study groups. No predictors of acute and late PVR were found. CONCLUSION: Ablation with a lower range of AI is highly effective and is not associated with a higher rate of acute and late PVR. No predictors of PV reconnection were found.

Impact of sacubitril/valsartan on implantable defibrillator eligibility in heart failure: a real-world experience.

OBJECTIVE: Current guidelines recommend an implantable cardiac defibrillator (ICD) in patients with symptomatic heart failure and reduced ejection fraction (HFrEF; left ventricular ejection fraction [LVEF] ≤35%) despite ≥3 months of optimal medical therapy. Recent observations demonstrated that sacubitril/valsartan induces beneficial reverse cardiac remodeling in eligible HFrEF patients. Given the pivotal role of LVEF in the selection of ICD candidates, we sought to assess the impact of sacubitril/valsartan on ICD eligibility and its predictors in HFrEF patients. PATIENTS AND METHODS: We retrospectively evaluated 48 chronic HFrEF patients receiving sacubitril/valsartan and previously implanted with an ICD in primary prevention. We assumed that ICD was no longer necessary if LVEF improved >35% (or >30% if asymptomatics) at follow-up. RESULTS: Over a median follow-up of 11 months, sacubitril/valsartan induced a significant drop in LV end-systolic volume (-16.7 ml/m2, p=0.023) and diameter (-6.8 mm, p=0.022), resulting in a significant increase in LVEF (+3.9%, p<0.001). As a consequence, 40% of previously implanted patients resulted no more eligible for ICD at follow-up. NYHA class improved in 50% of the population. A dose-dependent effect was noted, with higher doses associated to more reverse remodeling. Among patients deemed no more eligible for ICD, lower NYHA class (odds ratio (OR) 3.73 [95% CI 1.05; 13.24], p=0.041), better LVEF (OR 1.23 [95% CI 1.01; 1.48], p=0.032) and the treatment with the intermediate or high dose of sacubitril/valsartan (OR 5.60 [1.15; 27.1], p=0.032) were the most important predictors of status change. CONCLUSIONS: In symptomatic HFrEF patients, sacubitril/valsartan induced beneficial cardiac reverse remodeling and improved NYHA class. These effects resulted in a significant reduction of patients deemed eligible for ICD in primary prevention.

An enigmatic case of cardiac death in an 18-years old girl.

We report a case of unusual and unexplained cardiac death in an 18-years old female patient with congenital neurosensorial deafness. The fatal event was characterized by an initial syncopal episode, associated with a wide QRS tachycardia (around 110 bpm) but stable hemodynamic conditions. The patient, however, subsequently developed severe hypotension and progressive bradyarrhythmias until asystole and lack of cardiac response to resuscitation maneuvers and ventricular pacing.

Performance and clinical comparison between left ventricular quadripolar and bipolar leads in cardiac resynchronization therapy: Observational research.

AIM: To evaluate Attain Performa (Medtronic, Dublin, Ireland) quadripolar lead performance in clinical practice and, secondarily, to compare its long term clinical outcomes vs bipolar leads for left ventricular (LV) pacing. METHODS AND RESULTS: We retrospectively analyzed clinical, procedural and follow-up data of 215 patients implanted with a quadripolar lead. One hundred and twenty one patients implanted with bipolar lead were selected to compare long-term clinical outcomes. The quadripolar lead was implanted in the target vein in 196 patients (91%) without acute dislodgements. In 50% of patients the chosen final pacing configuration at implant would not have been available with bipolar leads. A dedicated quadripolar pacing vector was chosen more frequently when the LV tip location was apical than otherwise (65.6% vs 42.7%, p=0.003). After a median follow-up of 14 months, the LV pacing threshold was less than 2.5V at 0.4ms in 98 patients (90%) with a safety margin between phrenic nerve and LV pacing threshold >3V in 97 patients (89%). We observed a slight trend toward a lower risk of heart failure worsening and a lower incidence of ventricular arrhythmias and pulmonary congestion in patients implanted with quadripolar leads compared with the control group. CONCLUSION: Quadripolar leads improve the management of phrenic nerve stimulation at no trade-off with pacing threshold and lead stability. Quadripolar leads seems to be associated with a lower incidence of VT/VF and pulmonary congestion, when compared with bipolar leads, but further investigations are necessary to confirm that this positive effect is associated with better LV reverse remodeling.

A telemonitoring platform for the investigation of blood pressure profiles in pacemaker patients.

Rate responsive pacemakers (PM) use different strategies to adapt the patient paced rate, with the aim of having the best hemodynamic performance in response to internal or external conditions. Closed-loop stimulation (CLS) uses intracardiac impedance as a sensor principle. The evaluation of impact of different pacing modalities and technologies on the blood pressure (BP) profiles is mainly investigated in short-term laboratory settings, mainly due to the need of reliable daily-based BP values. The impact of CLS pacing on systemic blood pressure (BP) has been studied on short term basis, but data on long term effects are scarse. This study present a telemedicine platform designed for evaluating the effect of the rate responsive technology on daily systolic and diastolic BP data. BP and pacemaker data were collected daily from fourteen patients during a 3 month period. The total number of monitoring days was 1277 (91 day/patient), for a total number of 4455 BP measures. On average 3.5 measure/day/patient were received). The analysis of the BP data showed that CLS pacing results in diastolic pressure closer to the normal values than accelerometer-based pacing, which were associated to lower diastolic pressures.

[Gastrointestinal stromal tumors: our experience]. / Tumori stromali gastrointestinali: nostra esperienza.

The authors report their experience on the treatment of GIST. They point out the importance of classification of the disease in low, medium and high risk neoplasms based on the characteristic of the tumour: site, volume and mytotic index as the Consensus Conference of Bethesda recently established. Surgical procedure remains the most important treatment in localized disease, while patients with advanced disease can benefit from imatinib, a chemotherapeutic agent recently introduced, as an adjuvant therapy.

[Treatment of hemorrhoids with circular mechanic stapler]. / Trattamento della patologia emorroidaria con suturatrice meccanica circolare.

In a pilot study undertaken in collaboration with the Department of Surgery of "San Carlo di Nancy" Hospital in Rome, over the period form January 1998 to February 2000, 128 patients with haemorrhoidal disease underwent surgery using a circular stapler to "lift" the mucous-haemorrhoidal prolapse, according to the pathogenetic theory discussed here below. We compared the results of our series with those of a retrospective series of 80 patients that undergoing traditional surgery (Khubchandani 45, Milligan-Morgan 30, Whitehead 5), evaluating length of operation, postoperative pain and complications. Our preliminary data show that the technique requires only a short learning period, reduces the length of the operation, reduces the medium- and long-term pain and allows mables the patient to resume full working activity earlier.

Induction of interleukin-1beta and interleukin-6 gene expression in hypoperfused skeletal muscle of patients with peripheral arterial disease.

BACKGROUND: A growing amount of data supports the role of inflammation in the pathophysiology of atherosclerotic diseases but the cellular source of cytokines has not been clearly identified. Cytokines could be produced by inflammatory cells, activated endothelial and smooth muscle cells, and by the tissue exposed to recurrent ischemia. Accordingly, we evaluated whether hypoperfusion induces gene expression of interleukin (IL)-1beta and IL-6 in the skeletal muscle of patients with peripheral arterial disease and critical limb ischemia. METHODS: Skeletal muscle biopsies were obtained, during a femoral-distal bypass, from normoperfused (control) and hypoperfused skeletal muscles in 8 patients. Gene expression was assessed by semiquantitative reverse transcriptase-polymerase chain reaction, using glyceraldehyde-phosphate-deydrogenase mRNA levels as a normalization factor. RESULTS: In the hypoperfused biopsies, the level of IL-1beta gene expression was significantly higher in all but 2 patients (mean upregulation > 8.8 fold, p = 0.043), and the level of IL-6 gene expression was significantly higher in all but 1 patient (mean upregulation > 23.7 fold, p = 0.031). CONCLUSIONS: We report that IL-1beta and IL-6 gene expression is markedly upregulated in hypoperfused skeletal muscle of patients with critical lower limb ischemia. To our knowledge this is the first report of a local activation of the inflammatory cascade at the level of hypoperfused skeletal muscle. This activation, which could worsen symptoms and tissue viability and be involved in the pathophysiology of reperfusion injury, might be considered as a therapeutic target. It remains to be investigated whether our results may also apply to coronary artery disease.
