Background and Objectives: Dental caries has seen an increase in untreated cases, leading to significant health and quality-of-life impacts, necessitating innovative approaches like the promising non-operative management with silver diamine fluoride. This study aimed to evaluate the mechanisms of action of silver diamine fluoride on arresting dental caries in primary teeth. Materials and Methods: A systematic search was conducted across MEDLINE (PubMed), Google Scholar, and Wiley Online Library, including both in vivo and in vitro studies published from 1 January 2017 to 16 October 2022. ⋯ Modified silver diamine fluoride application techniques, including light curing or laser irradiation, enhanced efficacy, with light curing notably increasing surface microhardness. Based on a limited number of studies, no statistically significant differences in clinical effectiveness were observed with higher silver diamine fluoride concentrations or extended application durations. Conclusions: Silver diamine fluoride effectively induces quantitative changes in oral microflora and enhances the microhardness and mineral density of enamel and dentine in primary teeth, with modified application methods showing potential for improved outcomes.

Introduction: 5-phosphodiesterase inhibitors (PDE-5I) have been investigated as a treatment for urinary dysfunction for almost a decade. The general perception is that they play a significant role in managing lower urinary tract symptoms (LUTS), particularly those associated with benign prostatic hyperplasia (BPH). However, the specific biochemical processes by which PDE-5I repairs urinary function are still poorly understood and there is little instrumental evidence of significant improvement in urinary symptoms. ⋯ Conclusions: PDE-5I seems effective in relieving symptoms of some BPH patients when administered as complementary to agents currently used to treat BPH. However, the mechanism of action of PDE-5 inhibitors in LUTS remains poorly understood and it is difficult to determine the specific subset of BPH patients who will benefit from the combination of PDE-5 inhibitors with the current treatment. Well-designed, sufficiently informative comparative studies focusing on specific target group profiles (age, urogenital parameters) are needed to define new therapeutic options.

Despite medical advances, sepsis and septic shock remain some of the leading causes of mortality worldwide, with a high inter-individual variability in prognosis, clinical manifestations and response to treatment. Evidence suggests that pulmonary sepsis is one of the most severe forms of sepsis, while liver dysfunction, left ventricular dysfunction, and coagulopathy impact the prognostic. Sepsis-related hypothermia and a hypoinflammatory state are related to a poor outcome. ⋯ The progression to organ deficiencies refers to the individual particularities of sepsis-related multi-organ failure. Finally, the patient's trajectory in the ICU points out the need for a better understanding of interindividual responses to various supportive therapies. This review aims to identify the main sources of variability in clustering septic patients in various clinical phenotypes as a useful clinical tool for a precision-based approach in sepsis and septic shock.

Background and Objectives: Hepatic resection offers promising outcomes for patients with hepatocellular carcinoma (HCC) but can be constrained by factors like patient suitability. Continuous advancements in laparoscopic and robotic technologies have made minimally invasive hepatectomies (MIHs) a viable alternative to open hepatectomies with benefits in terms of recovery and complications. Materials and Methods: We completed a retrospective review on 138 HCC patients who underwent OH or MIH between 2010 and 2020 at the Hume-Lee Transplant Center. ⋯ The reduced LOS and operation time enhance its feasibility, and older patients previously denied for curative resection may qualify for MIH. Preoperative TACE also enhances survival outcomes, emphasizing its general role in managing resectable HCCs. Both robotic and laparoscopic hepatectomies offer acceptable short- and long-term clinical outcomes, highlighting MIH as the standard choice for HCC patients.

Bilateral acute retinal necrosis (BARN) represents a broad ophthalmological field of severe retinal pathologies associated with poor visual prognosis and blindness. The purpose of this review is to examine the clinical spectrum in detail over the past few years, exploring laboratory and instrumental diagnosis, and providing useful and up-to-date guidance in this field. A systematic review of this field has been performed through the PRISMA guidelines, searching in the PUBMED database. ⋯ Anatomical and functional recovery is unfavorable if they are not individuated in a quick time. Early diagnosis and timely treatment offer a better chance of visual improvement and the avoidance of complications. Complications worsen the visual prognosis over months and may require a surgical approach.
