Review
The aim of the present study was to integrate the available data published in the literature on oral and maxillofacial neuroendocrine carcinomas concerning the demographic, clinical and histopathological features of this condition. An electronic search with no publication date restriction was undertaken in April 2021 in four databases. Eligibility criteria included reports published in English having enough data to confirm a definite diagnosis, always showing a neuroendocrine marker. Cases originating in the oropharynx, including base of the tongue and tonsils, were excluded. Outcomes were evaluated by the Kaplan-Meier method along with Cox regression. Twenty-five articles (29 cases) from nine different countries were detected. Mean patient age was 56.3 (± 17.5) years, with a slight male predilection. Symptomatology was present in 72.2% of informed cases. Regarding clinical presentation, a non-ulcerated nodule located in the gingiva with a mean size of 3.4 (± 2.0) cm was most frequently reported. Concomitant metastasis was identified in seven individuals. Histopathologically, most neoplasms were of the small cell type, and immunohistochemistry for both epithelial and neuroendocrine differentiation was used in 65.5% cases. Radical surgery was the treatment of choice in almost all cases, with or without adjuvant therapy. Mean follow-up was 20.5 (± 21.2) months, and only four patients developed recurrences. Eleven (44.0%) individuals died due to the disease. Ulcerated lesions were a prognostic factor. This study provides knowledge that can assist surgeons, oncologists, and oral and maxillofacial pathologists with the diagnosis and management of neuroendocrine carcinomas. Our findings demonstrated that the long-term prognosis of this lesion continues to be poor.

Review
Body packing is the term used for the intracorporeal concealment of illicit drugs, mainly cocaine, heroin, methamphetamine, and cannabinoids. These drugs are produced in the form of packages and are swallowed or placed in various anatomical cavities and body orifices. Basing on these two ways of transportation a distinction between body stuffers and body pushers can be made, with the former described as drug users or street dealers who usually carry small amounts of drugs and the latter as professional drug couriers who carry greater amounts of drugs. A review of the literature regarding body packing is presented, with the aim to highlight the toxicological and radiological features related to this illegal practice. Raising awareness about the encountered mean body levels of the drugs and the typical imaging signs of the incorporated packages could be useful for clinicians and forensic pathologists to (a) identify possible unrecognized cases of body packing and (b) prevent the serious health consequences and deaths frequently occurring after the packages' leakage or rupture or the packages' mass obstructing the gastrointestinal lumen.

Surgical Endoscopy Apr 2022Evidence and practice recommendations on the use of transanal total mesorectal excision (TaTME) for rectal cancer are conflicting. (Meta-Analysis)
Meta-Analysis
BACKGROUND
Evidence and practice recommendations on the use of transanal total mesorectal excision (TaTME) for rectal cancer are conflicting.
OBJECTIVE
We aimed to summarize best evidence and develop a rapid guideline using transparent, trustworthy, and standardized methodology.
METHODS
We developed a rapid guideline in accordance with GRADE, G-I-N, and AGREE II standards. The steering group consisted of general surgeons, members of the EAES Research Committee/Guidelines Subcommittee with expertise and experience in guideline development, advanced medical statistics and evidence synthesis, biostatisticians, and a guideline methodologist. The guideline panel consisted of four general surgeons practicing colorectal surgery, a radiologist with expertise in rectal cancer, a radiation oncologist, a pathologist, and a patient representative. We conducted a systematic review and the results of evidence synthesis by means of meta-analyses were summarized in evidence tables. Recommendations were authored and published through an online authoring and publication platform (MAGICapp), with the guideline panel making use of an evidence-to-decision framework and a Delphi process to arrive at consensus.
RESULTS
This rapid guideline provides a weak recommendation for the use of TaTME over laparoscopic or robotic TME for low rectal cancer when expertise is available. Furthermore, it details evidence gaps to be addressed by future research and discusses policy considerations. The guideline, with recommendations, evidence summaries, and decision aids in user-friendly formats can also be accessed in MAGICapp: https://app.magicapp.org/#/guideline/4494 .
CONCLUSIONS
This rapid guideline provides evidence-informed trustworthy recommendations on the use of TaTME for rectal cancer.

PURPOSE
Research interest in telehealth and autism spectrum disorder (ASD) has grown. There is a need to review the literature to allow speech-language pathologists (SLPs) and other service providers to consider applicability to their settings. The aim of this review was to examine the nature and outcomes of studies examining telehealth assessment and/or intervention in ASD.
METHOD
A systematic search of the literature was undertaken, with 14 studies meeting inclusion criteria. The authors extracted information from each included article, including participant characteristics, technology used, measures and reported outcomes. Quality review of articles was undertaken.
RESULT
The 284 participants with ASD across the 14 included studies ranged in age from 19 months to adulthood. The quality of the studies varied. A range of services were provided via telehealth, including diagnostic assessments, early intervention and language therapy. Results suggested that services delivered via telehealth were equivalent to services delivered face to face, and superior to comparison groups without telehealth sessions.
CONCLUSION
The findings suggest there may be a range of benefits in using telehealth with individuals with ASD, their families, and teachers. Further research, however, is required particularly regarding the use of telehealth directly with children with ASD for assessment and intervention.

Review
OBJECTIVE
The likelihood of timely treatment for cervical cancer increases with timely detection of abnormal cervical cells. Automated methods of detecting abnormal cervical cells were established because manual identification requires skilled pathologists and is time consuming and prone to error. The purpose of this systematic review is to evaluate the diagnostic performance of artificial intelligence (AI) technologies for the prediction, screening, and diagnosis of cervical cancer and pre-cancerous lesions.
MATERIALS AND METHODS
Comprehensive searches were performed on three databases: Medline, Web of Science Core Collection (Indexes = SCI-EXPANDED, SSCI, A & HCI Timespan) and Scopus to find papers published until July 2022. Articles that applied any AI technique for the prediction, screening, and diagnosis of cervical cancer were included in the review. No time restriction was applied. Articles were searched, screened, incorporated, and analyzed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines.
RESULTS
The primary search yielded 2538 articles. After screening and evaluation of eligibility, 117 studies were incorporated in the review. AI techniques were found to play a significant role in screening systems for pre-cancerous and cancerous cervical lesions. The accuracy of the algorithms in predicting cervical cancer varied from 70% to 100%. AI techniques make a distinction between cancerous and normal Pap smears with 80-100% accuracy. AI is expected to serve as a practical tool for doctors in making accurate clinical diagnoses. The reported sensitivity and specificity of AI in colposcopy for the detection of CIN2+ were 71.9-98.22% and 51.8-96.2%, respectively.
CONCLUSION
The present review highlights the acceptable performance of AI systems in the prediction, screening, or detection of cervical cancer and pre-cancerous lesions, especially when faced with a paucity of specialized centers or medical resources. In combination with human evaluation, AI could serve as a helpful tool in the interpretation of cervical smears or images.

Meta-Analysis Review
OBJECTIVE
Pre-eclampsia (PE) is associated with impaired trophoblastic invasion and typical villous and vascular placental lesions. The primary aim of this study was to quantify the prevalence of placental histopathological lesions in pregnancies complicated by PE.
METHODS
MEDLINE, EMBASE and CINAHL were searched electronically, and relevant articles reporting on placental histopathological lesions were assessed according to the following criteria: study design, number of pregnancies included, severity of PE and whether the pathologist was blinded to the clinical information. Prospective and retrospective case-control studies including ≥ 100 pregnancies were included in the systematic review. The incidence of each type of histological lesion according to the Perinatal Section of the Society for Pediatric Pathology classification in pre-eclamptic and normal pregnancies was identified, and lesions were categorized into two main groups: villous lesions and vascular lesions. Random-effects meta-analysis of proportions was used for analysis. Between-study heterogeneity was assessed using the I statistic.
RESULTS
The search yielded 717 citations, and a total of eight studies (four blinded and four non-blinded) were included in the review. In unblinded studies, the pooled prevalence of villous lesions was 11.6% and 48.2% in normal and pre-eclamptic pregnancies, respectively, giving a pooled odds ratio (OR) of 7.59. In blinded studies, the pooled prevalence of villous lesions was 18.5% and 42.0% in normal and pre-eclamptic pregnancies, respectively, giving a pooled OR of 4.28. In unblinded studies, the pooled prevalence of vascular lesions was 8.1% and 37.3% in normal and pre-eclamptic pregnancies, respectively, giving a pooled OR of 20.34. In blinded studies, the pooled prevalence of vascular lesions was 9.8% and 38.9%, in normal and pre-eclamptic pregnancies, respectively, giving a pooled OR of 7.08.
CONCLUSIONS
In blinded studies, the incidence of both placental villous and vascular histopathological lesions is four- to seven-fold higher in pre-eclamptic than in normal pregnancies. Greater differences are reported in unblinded studies. Despite the higher probability (point prevalence) of finding abnormal placental pathology in pregnancies with PE, placental lesions are not specific to the diagnosis of PE. Copyright © 2017 ISUOG.

Review
PURPOSE
Trauma-related preventable death (TRPD) has been used to assess the management and quality of trauma care worldwide. However, due to differences in terminology and application, the definition of TRPD lacks validity. The aim of this systematic review is to present an overview of current literature and establish a designated definition of TRPD to improve the assessment of quality of trauma care.
METHODS
A search was conducted in PubMed, Embase, the Cochrane Library and the Web of Science Core Collection. Including studies regarding TRPD, published between January 1, 1990, and April 6, 2021. Studies were assessed on the use of a definition of TRPD, injury severity scoring tool and panel review.
RESULTS
In total, 3,614 articles were identified, 68 were selected for analysis. The definition of TRPD was divided in four categories: I. Clinical definition based on panel review or expert opinion (TRPD, trauma-related potentially preventable death, trauma-related non-preventable death), II. An algorithm (injury severity score (ISS), trauma and injury severity score (TRISS), probability of survival (Ps)), III. Clinical definition completed with an algorithm, IV. Other. Almost 85% of the articles used a clinical definition in some extend; solely clinical up to an additional algorithm. A total of 27 studies used injury severity scoring tools of which the ISS and TRISS were the most frequently reported algorithms. Over 77% of the panels included trauma surgeons, 90% included other specialist; 61% emergency medicine physicians, 46% forensic pathologists and 43% nurses.
CONCLUSION
The definition of TRPD is not unambiguous in literature and should be based on a clinical definition completed with a trauma prediction algorithm such as the TRISS. TRPD panels should include a trauma surgeon, anesthesiologist, emergency physician, neurologist, and forensic pathologist.

Review
The recovery of severely altered cadavers (i.e., extensively decomposed, mummified, charred or dismembered) can be a challenge for forensic pathologists due to the difficulties in identification, PMI estimation and manner and cause of death determination. In such cases, integrating routine approaches (autopsy, histology, toxicology) to more specific forensic branches can be fundamental to improving the investigative process. In this paper a systematic review using PubMed, Scopus and Web of Science databases has been performed. The aim was to evaluate the forensic approaches implemented in the management of severely altered bodies due to decomposition, mummification, skeletonization, charring or dismemberment (to which we refer to as "complex"), and the role of each approach in the solution of a case. Then, the literature revision results were used to propose a schematic flowchart summarizing the post mortem activities that can be performed in forensic practice, adaptable in relation to each case.

Review
Oral cancer (OC) is one of the most common forms of head and neck cancer and continues to have the lowest survival rates worldwide, even with advancements in research and therapy. The prognosis of OC has not significantly improved in recent years, presenting a persistent challenge in the biomedical field. In the field of oncology, artificial intelligence (AI) has seen rapid development, with notable successes being reported in recent times. This systematic review aimed to critically appraise the available evidence regarding the utilization of AI in the diagnosis, classification, and prediction of oral cancer (OC) using histopathological images. An electronic search of several databases, including PubMed, Scopus, Embase, the Cochrane Library, Web of Science, Google Scholar, and the Saudi Digital Library, was conducted for articles published between January 2000 and January 2023. Nineteen articles that met the inclusion criteria were then subjected to critical analysis utilizing QUADAS-2, and the certainty of the evidence was assessed using the GRADE approach. AI models have been widely applied in diagnosing oral cancer, differentiating normal and malignant regions, predicting the survival of OC patients, and grading OC. The AI models used in these studies displayed an accuracy in a range from 89.47% to 100%, sensitivity from 97.76% to 99.26%, and specificity ranging from 92% to 99.42%. The models' abilities to diagnose, classify, and predict the occurrence of OC outperform existing clinical approaches. This demonstrates the potential for AI to deliver a superior level of precision and accuracy, helping pathologists significantly improve their diagnostic outcomes and reduce the probability of errors. Considering these advantages, regulatory bodies and policymakers should expedite the process of approval and marketing of these products for application in clinical scenarios.

PURPOSE
Community aphasia groups (CAGs) can provide a range of benefits to people with aphasia and support long-term psychosocial wellbeing. However, the dominant speech-pathologist-led service delivery model is inherently limited in scope. Peer-led groups hold potential as a sustainable and empowering extension of this traditional model. The implementation of peer-led models likely requires targeted training and support, however little is known about the characteristics and impacts of CAG facilitation. This study reviews the literature on CAGs and their facilitation.
MATERIALS AND METHODS
We conducted a scoping review on this topic.
RESULTS
One hundred and seventy-seven texts were included, reporting on a heterogeneous range of activities. Most texts reported on speech-pathologist-led groups, however, a range of alternative models were also represented. While no studies directly compared the impacts of different facilitation models, some comparative benefits could be drawn from the literature. Facilitation was perceived as complex and challenging, and significant gaps were identified in the training of facilitators. Ten qualitative studies investigated characteristics and impacts of facilitator behaviours, providing a useful foundation for future development of training and evaluation tools.
CONCLUSIONS
Further investigation into alternative facilitation models and facilitator training needs will likely support the proliferation of high-quality CAGs.Implications for RehabilitationCommunity aphasia groups (CAGs) play an important role in supporting identity and wellbeing for individuals with chronic aphasia.The traditional speech-pathology led model of group service delivery is limited in scope; the addition of peer- and volunteer-led CAGs may facilitate access to groups and meet a range of different needs for individuals with aphasia.CAG facilitation is a complex and challenging task, likely requiring specialised training, however, this has not been widely available to facilitators.The development of specialised facilitator training will likely support the proliferation of sustainable and high-quality CAGs.
