When compared to the RoE and RoW, this further decrease from March 2020 to April 2020 in Italy was significantly less (p=0.005), most likely reflecting the earlier effects of the containment measures in Italy, taken earlier than anywhere else in the West.
The COVID-19 pandemic massively hit Italy and caused a disruption of healthcare services, including cardiac imaging studies. This raises concern about the medium- and long-term consequences for the high number of patients who were denied timely diagnoses and the subsequent lifesaving therapies and procedures.

The purpose of this study was to compare clinically and radiographically the effects of potassium nitrate in polycarboxylate cement and mineral trioxide aggregate (MTA) as pulpotomy agents in vital immature mandibular first molars.
The trial design was a parallel randomized, 11 allocation ratio, with both the participants and the data assessor blinded. A total of 50molars of 48 eligible children aged 6-9years were studied. The children had mandibular immature first molars with extensive caries that revealed pulp exposure during caries excavation. Patients were randomly allocated equally into 2 groups in which potassium nitrate in polycarboxylate cement (the intervention group) and MTA (the control group) were used as pulpotomy biomaterials. The treated teeth were restored permanently. The primary outcome was clinical/radiographic assessment after 1week, 6 months, and 12months. The secondary outcomes were radiometric analysis at 6 and 12months to determine dimensional changes during maturogenesis. The digi.
The clinical and radiographic success reported in the present study reveals that potassium nitrate in polycarboxylate cement could be used as a biological and economic alternative to MTA as a pulpotomy agent in vital immature mandibular first molars. Further follow-up for longer periods is recommended.
The aim of this systematic review was to evaluate the existing randomized controlled trials (RCTs) on the safety and efficacy of vital pulp therapy (VPT) and to analyze the outcomes of VPT performed with a variety of pulp-capping materials and techniques.
MEDLINE (PubMed), Embase, Cochrane Library, and gray literature were searched (January 2000-March 2021). Study selection and data extraction were performed in duplicate. Eligible RCTs were critically appraised for risk of bias and quality of evidence and were meta-analyzed to estimate the treatment effects.
Fourteen studies were included. The pooled success rate of VPT using contemporary capping materials such as mineral trioxide aggregate (MTA) or calcium silicate-based materials (CSMs) was 93.2% (95% confidence interval [CI], 91.6%-94.9%). Multiple subgroup analyses by different etiologies, procedure types, developmental stages of teeth, and preoperative diagnoses were performed. Analyses presented low certainty of evidence. No significant difference was noted between MTA and CSM at 12months or a longer follow-up (risk ratio =0.99; 95% CI, 0.95-1.03) with low certainty of evidence. Laser-assisted VPT failed to show significantly better outcomes than conventional VPT (risk ratio=1.19; 95% CI, 0.99-1.49) with very low certainty of evidence.
When MTA or CSM was used as a capping material, VPT was 93% successful. The techniques, etiologies, developmental stages of teeth, and preoperative diagnosis had no significant influence on treatment outcomes. No major adverse effects (except discoloration associated with the use of MTA) were identified. The overall quality of evidence was low.

Crown fractures are a common type of traumatic dental injury. Various factors may affect the outcome of crown fractures. This study aimed to evaluate the treatment outcomes of immature teeth with a crown fracture.
This retrospective cohort study included patients who presented to a dental trauma center from 2008-2018 with a history of a crown fracture of immature teeth and at least 6months of follow-up. Outcomes of primary endodontic or restorative interventions as well as reinterventions were evaluated. Kaplan-Meier curves were used to compare the unadjusted differences in survival time. Logistic and Cox regression analyses were performed to identify potential predictors for complication and survival time, respectively.
The success rates of the primary interventions for 99 teeth (72 patients) after a median follow-up of 22months were as follows cervical pulpotomy (90.4%), partial pulpotomy (85.2%), mineral trioxide aggregate apical barrier (80.0%), root canal treatment (66.6%), and only restoration (47.2%). Teeth that received vital pulp therapy were less prone to complications (adjusted hazard ratio=0.21; 95% confidence interval, 0.09-0.53; P<.05), whereas those with concomitant luxation injuries were more susceptible to complications (adjusted odds ratio=2.90; 95% confidence interval, 1.01-8.29; P<.05).
Crown fractures had a relatively high favorable prognosis. Vital pulp therapy (partial or cervical pulpotomy) had the highest success rate, whereas cases that received only restoration had the lowest success rate. Teeth with concomitant luxation injuries had more odds and hazards of complications.

Bats found in Brazil are small, which can lead to situations in which there are limitations in the collection of the central nervous system (CNS) and the amount of material may be insufficient to carry out laboratory diagnostic techniques for rabies. The objective of this work was to evaluate an alternative sample collection for the diagnosis of rabies in bats. A total of 92 bat samples, 82 positives and 10 negatives were selected. The cranial cavity was scraped with the aid of sterile tips and a virus diluent was added to create a suspension. All samples were submitted to Rabies Tissue Culture Infection Test (RTCIT) and reverse transcription polymerase chain reaction (RT-PCR). The diagnostic sensitivity and specificity of the RTCIT and RT-PCR using the cranial cavity lavage were calculated in comparison with the results of the laboratory routine (DFAT and RTCIT) performed with the CNS (considered gold standard). The results of the RTCIT show that the cranial cavity lavage is not an adequate sample for viral isolation, since the diagnostic sensitivity was low (37.8 %) when compared with the tests with the CNS. However, the RT-PCR of the cranial cavity lavage may be a tool to assist in the diagnosis, since it presented a sensitivity of 76.8 %. The results of this study suggest that cranial cavity lavage is an interesting alternative to enable the diagnosis of rabies in bats and increases the possibility of diagnosis contributing to rabies surveillance and control.

Worldwide, digital devices are improving every stage of the patient care pathway. For one, sensors are being used to monitor patient metrics 24/7, permitting swift diagnosis and interventions. At the treatment stage, 3D printers are currently being investigated for the concept of personalised medicine by allowing patients access to on-demand, customisable therapeutics. Robots are also being explored for treatment, by empowering precision surgery or targeted drug delivery. Within medical logistics, drones are being leveraged to deliver critical treatments to remote areas, collect samples, and even provide emergency aid. To enable seamless integration within healthcare, the Internet of Things technology is being exploited to form closed-loop systems that remotely communicate with one another. This review outlines the most promising healthcare technologies and devices, their strengths, drawbacks, and scopes for clinical adoption.Photomedicine has long been used for treating cancerous diseases. With advances in chemical and material sciences, various types of light-activated photosensitizers (PSs) have been developed for effective photodynamic therapy (PDT) and photothermal therapy (PTT). However, conventional organic/inorganic materials-based PSs lack disease recognition capability and show limited therapeutic effects in addition to side effects. Recently, intelligent dynamic nanoassemblies that are activated in a tumor environment have been extensively researched to target diseased tissues more effectively, for increasing therapeutic effectiveness while minimizing side effects. This paper presents the latest dynamic nanoassemblies for effective PDT or PTT and combination phototherapies, including immunotherapy and image-guided therapy. Dynamic self-assembly exhibits great potential for clinical translation in diagnosis and treatment through its integrated versatility. Nanoassemblies based on multidisciplinary technology are a promising technique for treating incurable cancerous diseases in the future.
