Meta-Analysis
Eosinophilic solid and cystic renal cell carcinoma (ESC-RCC) is a novel and uncommon type of renal cell carcinoma, which has been recently recognized and introduced as a distinct entity in the WHO 2022 kidney tumor classification. Previously known as "unclassified RCC", followed by "tuberous sclerosis complex (TSC)-associated RCC", ESC-RCC is now a distinct category of kidney tumor, with its own name, with specific clinical manifestations, and a unique morphological, immunohistochemical and molecular profile. Due to its recent introduction and the limited available data, the diagnosis of ESC-RCC is still a complex challenge, and it is probably frequently misdiagnosed. The secret of diagnosing this tumor lies in the pathologists' knowledge, and keeping it up to date through research, thereby limiting the use of outdated nomenclature. The aim of our case-based review is to provide a better understanding of this pathology and to enrich the literature with a new case report, which has some particularities compared to the existing cases.

Meta-Analysis Review
BACKGROUND
Cardiac implantable electronic devices (CIED) are a heterogeneous group of medical devices with increasingly sophisticated diagnostic capabilities, which could be exploited in forensic investigations. However, current guidelines are lacking clear recommendations on the topic. The first aim of this systematic review is to provide an updated assessment of the role of postmortem CIED interrogation, and to give practical recommendations, which can be used in daily practice. Secondly, the authors aim to determine the rates of postmortem CIED interrogation and autopsy investigations, the type of final rhythm detected close to death (with a focus on the significance of documented arrhythmias), as well as the role of postmortem CIED interrogation in the determination of final cause/time of death, and any potentially fatal device malfunctions.
METHODS
A systematic search in MEDLINE and Scopus aiming to identify reports concerning postmortem human CIED interrogation was performed, including a systematic screening of reference lists. Case reports, letters to the editors, commentaries, review articles or guidelines were excluded, along with studies related to cardiac devices other than CIED. All data were pooled and analyzed using fixed-effects meta-analysis models, and the I statistic was used to assess heterogeneity.
RESULTS
A total of 25 articles were included in the systematic review, enrolling 3194 decedent CIED carriers. Ten studies (40%) had a 100% autopsy rate, whereas in further 6 studies autopsy findings were variably reported; CIED interrogation was available from 22 studies (88%), and it was never performed prior to autopsy. The overall rate of successful postmortem CIED interrogation was 89%, with high heterogeneity among studies, mainly due to device deactivation/battery discharge. Twenty-four percent of CIED carriers experienced sudden cardiac death (SCD), whereas non-sudden cardiac and non-cardiac death (NSCD, NCD) were reported in 37% and 30% of decedents, respectively. Ventricular tachyarrhythmias were recorded in 34% of overall successfully interrogated CIED, and in 62% of decedents who experienced a SCD; of all ventricular tachyarrhythmias recorded, 40% was found in NSCD or NCD. A clear interpretation of the etiological role of recorded arrhythmias in the causation of death required integration with autopsy findings. Overall, potentially fatal device malfunctions were detected in 12% of cases.
CONCLUSIONS
Postmortem CIED interrogation is a valuable tool for the determination of the cause of death, and may complement autopsy. Forensic pathologists need to know the potential utility, pitfalls, and limitations of this diagnostic examination to make this tool as much reliable as possible.

PURPOSE
There is an important need for interprofessional practice (IPP) between speech-language pathologists (SLPs) and classroom teachers (CTs) in mainstream schools to support student outcomes. This mixed methods systematic review aimed to synthesize existing literature to describe the experiences of IPP between SLPs and CTs in mainstream schools.
METHOD
A systematic review protocol was utilized to conduct a comprehensive search of six databases (PubMed Central, EMBASE, Cochrane Library, CINAHL EBSCO, ERIC, and ProQuest Dissertations & Theses Global) using key words related to the research question. A total of 1,876 unique studies were retrieved. Of these, 18 studies were identified as relevant to the research question, as they described the experiences of IPP between SLPs and CTs. Thematic analysis was used to analyze the quantitative and qualitative studies.
RESULTS
Six main themes describing IPP experiences were identified: (1) what are you bringing to the collaboration table? (2) putting the value in collaboration, (3) sharing is collaborating, (4) the nature of collaboration varies, (5) the educational context matters, and (6) influences to collaboration beyond professional control.
CONCLUSIONS
IPP between SLPs and CTs is complex, with various facilitators and barriers to IPP emerging within the education context. Competencies for SLPs and CTs related to having a shared understanding, adequate communication, and building relationships with each other help support IPP in schools. The utilization of a relationship-centered care approach between SLPs and CTs is also important to foster and support student outcomes.

Meta-Analysis
OBJECTIVE
Tongue-tie, which is also known as ankyloglossia, is a common condition where the lingual frenulum is unusually tight or short. While most literature investigates the impact of tongue-tie on breastfeeding, recent articles have examined its role in speech production in children. However, these have not previously been reviewed systematically. This study aims to determine the impact of tongue-tie on speech outcomes and assess whether frenectomy can improve speech function.
METHODS
In this systematic review, we conducted a comprehensive search of PubMed/MEDLINE, Cochrane Library, Embase, and speechBITE to analyze primary studies investigating the impact of frenectomy for tongue-tie on speech outcomes. We extracted data regarding patient age, male to female ratio, procedure type, follow-up time, and speech outcomes and ran statistical analyses to determine if frenectomy for tongue-tie leads to improvement in speech issues in pediatric patients. Speech outcomes extracted were subjectively measured based on the interpretation of a speech and language pathologist or parent.
RESULTS
Our analysis included 10 studies with an average patient age of 4.10 years, and average cohort size of 22.17 patients. Overall, frenectomy for tongue-tie was associated with an improvement in speech articulation (0.78; 95% CI: 0.64-0.87; < .01). Increasing patient age was found to be negatively correlated with post-frenectomy speech outcomes ( = .01). However, this relationship disappeared in the adjusted model.
CONCLUSION
Overall, we conclude that frenectomy is a suitable treatment to correct speech issues in select patients with tongue-tie if caught early in childhood. Despite the limited investigations around speech outcomes post-frenectomy, these results are informative to providers treating tongue-tie.

Review
Acute Myocardial Infarction (AMI) refers to the death of heart tissue in the absence ofperfusion. It is one of the top causes of death globally, particularly in middle andhigher-age groups. However, for the pathologist, the post-mortem macroscopic andmicroscopic diagnosis of early AMI remains challenging. In the early acute stage ofAMI, no microscopic visible signs of tissue alterations like necrosis and neutrophilinfiltration can be seen. In such a scenario, immunohistochemistry (IHC) accounts forthe most suitable and safest alternative to study early diagnostic cases by selectivelydetecting changes in the cell population. This systematic review focuses on themultiple causes/changes that lead to the privation of blood flow as well as tissuechanges induced by the absence of perfusion.We performed a systematic review of the last 10-15 years' publications that focused ondetecting immunohistochemical changes that appear in the cell population in case ofacute myocardial infarction. We found around 160 articles on AMI, which we narroweddown to 50 with the use of specific filters such as: "Acute Myocardial Infarction," "Ischemia," "Hypoxia," "Forensic," "Immunohistochemistry, and "Autopsy." The presentreview comprehensively highlights the current knowledge of specific IHC markers usedas gold standards during post-mortem investigation of acute myocardial infarction. Thepresent review comprehensively highlights the current knowledge of specific IHCmarkers used as gold standards during post-mortem investigation of acute myocardialinfarction, and some new potential immunohistochemical markers that can be used inthe early detection of myocardial infarction.

Review
Documented cases of sodium nitrite toxicity are almost exclusively caused by accidental ingestion; however, self-poisoning with sodium nitrite represents an increasing trend in nitrate-related deaths. This systematic review summarizes the most crucial evidence regarding the fatal toxicity of sodium nitrite. It identifies gaps and differences in the diagnostic forensic approaches and the detection methods of sodium nitrite intoxication. A total of eleven research articles were selected for qualitative and quantitative data. Most of the studies (6/11) were case reports. Fifty-three cases of fatal intoxication with sodium nitrite were chosen for the review. More research is required to develop cost-effective techniques and uniform cutoffs for blood nitrite and nitrate levels in the event of deadly sodium nitrite poisoning. There is still a lack of critical information on other matrices and the impact of time since death on toxicological results in such situations. The available evidence provides useful recommendations for forensic pathologists and health practitioners engaged in instances of sodium nitrite poisoning or death. The data should also set off alarm bells in the public health system, in prosecutor's offices, and for policymakers so that they may undertake preventative measures to stop and restrict the unregulated market for these substances.

Review
OBJECTIVE
Angiogenesis plays a vital role at the molecular level in various inflammatory lesions, that lead to their chronicity. Oral lichen planus is an immune-mediated chronic inflammatory disorder. The angiogenetic role and exact mechanisms in oral lichen planus are still unclear due to a dearth of studies. Its clinical significance with angiogenesis also requires further elucidation necessitating a thorough review of the studies that have been conducted so far. The present review was designed to identify the dependence of oral lichen planus progression on angiogenesis which could aid in devising metronomic treatments required to halt the progression of this disease.
MATERIALS AND METHODS
A thorough search was made using MEDLINE by PubMed, Scopus, Google scholar, Cochrane library, and EMBASE databases. Original research articles, that immunohistochemically evaluated angiogenesis in oral lichen planus were included for review. Risk of bias was analysed for each study using Modified Newcastle-Ottawa scale and Review Manager 5.4 was used to output its result.
RESULTS
Twenty-nine published articles were included for data synthesis. The most commonly employed antibody was CD34, however, upregulated VEGF expression was the principal while ICAM-1, VCAM-1, and PECAM-1 were critical angiogenic factors to mediate angiogenesis in oral lichen planus.
CONCLUSION
The current evidence supports that angiogenesis, a fundamental pathogenetic mechanism of oral lichen planus, leads to its persistence and chronicity. However, studies with a larger sample size, standard evaluation criteria, different subtypes, and adequate follow-up are warranted.

Review
INTRODUCTION
Suicidal hanging resulting in decapitation is rarely documented. This discussion involves a case of a 35-year-old man found decapitated in his residence's garden. A systematic literature review on hanging-induced decapitation was conducted to comprehensively investigate and compare the case to existing literature. The study aims to identify frequently described post-mortem findings in cases of suicidal hanging leading to decapitation.
CASE REPORT
A 35-year-old man was found decapitated in his garden, with a jute strap and chimney debris nearby. The cervical region was completely severed along the dorsoventral and craniocaudal plane, exposing internal structures. A ligature mark was present, along with Amussat's sign and Simon's bleeding.
METHODS
The systematic review of the literature followed PRISMA standards, analyzing 3622 publications from Google Scholar, PubMed, and Scopus databases up to 2023. Inclusion criteria comprised cases of complete or incomplete decapitation resulting from hanging, available in full-text and written in English.
RESULTS
16 articles on hanging-induced decapitation met the selection criteria; 22 cases were analyzed. Studies, mostly from Europe, showed a mean victim age of 44.3, all male. Fall height ranged from 1 m to 18 m, with various suspension media. Most cases displayed complete decapitation, primarily between cervical vertebrae C1 and C3. Some cases noted collateral findings.
CONCLUSIONS
Complete crime scene investigation and thorough post-mortem examination are crucial for reconstructing events, especially with confounding elements. Precise evidence collection and literature comparison are essential to understand the case and substantiate the forensic pathologist's hypothesis in court.

OBJECTIVES
The high incidence of prostate cancer causes prostatic samples to significantly affect pathology laboratories workflow and turnaround times (TATs). Whole-slide imaging (WSI) and artificial intelligence (AI) have both gained approval for primary diagnosis in prostate pathology, providing physicians with novel tools for their daily routine.
METHODS
A systematic review according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines was carried out in electronic databases to gather the available evidence on the application of AI-based algorithms to prostate cancer.
RESULTS
Of 6290 articles, 80 were included, mostly (59%) dealing with biopsy specimens. Glass slides were digitized to WSI in most studies (89%), roughly two-thirds of which (66%) exploited convolutional neural networks for computational analysis. The algorithms achieved good to excellent results about cancer detection and grading, along with significantly reduced TATs. Furthermore, several studies showed a relevant correlation between AI-identified histologic features and prognostic predictive variables such as biochemical recurrence, extraprostatic extension, perineural invasion, and disease-free survival.
CONCLUSIONS
The published evidence suggests that AI can be reliably used for prostate cancer detection and grading, assisting pathologists in the time-consuming screening of slides. Further technologic improvement would help widening AI's adoption in prostate pathology, as well as expanding its prognostic predictive potential.

Meta-Analysis Review
OBJECTIVE
Adenotonsillectomy is one of the most common surgical procedures performed on children. Caregivers are often concerned about voice change after the procedure, and such concerns remain unsettled. This meta-analysis analyzed voice change in children after adenotonsillectomy.
DATA SOURCES
The PubMed, Medline, EMBASE, and Cochrane databases.
REVIEW METHODS
The study protocol was registered on PROSPERO. Two authors independently searched for articles using keywords "adenoidectomy," "tonsillectomy, "voice," "nasalance,"and "speech." English articles specifying voice changes after adenotonsillectomy were pooled with standardized mean difference (SMD) using random-effects model. Evaluation methods were computerized acoustic voice analysis, aerodynamic analysis, nasometer, rhinomanometry, evaluations from a speech-language pathologist or otolaryngologist, and a caregiver assessment questionnaire.
RESULTS
Twenty-three studies with 2154 children were analyzed (mean age: 8.0 y; 58% boys; mean sample size: 94 children). Due to insufficient data for other outcome variables, this meta-analysis only summarized changes in the computerized acoustic voice analysis 1 month and 3 months after surgery. The computerized acoustic analysis revealed significant changes in jitter (SMD = -0.36; 95% confidence interval [CI]: -0.60 to -0.11), shimmer (SMD = -0.34; 95% CI: -0.57 to -0.11), and soft phonation index (SMD = -0.36; 95% CI: -0.57 to -0.15) at 1 month after surgery. Parameters including fundamental frequency, jitter, noise-to-harmonics ratio, and shimmer were not significantly changed at 3 months after surgery.
CONCLUSIONS
This meta-analysis observed small improvements in jitter, shimmer, and soft phonation index 1 month after surgery. No significant effects were observed in voice outcomes 3 months after surgery. Laryngoscope, 134:2538-2550, 2024.
