Independent reporting in oral and maxillofacial pathology.

AIMS: To understand the current practice, extent of use and barriers related to independent reporting (IR) in oral and maxillofacial pathology (OMFP) training in the UK. METHODS: A questionnaire was created containing questions about the experiences and opinions surrounding IR in OMFP. The target participants were (1) consultants in OMFP who had been involved in training OMFP trainees in the last 5 years and (2) current OMFP trainees. The questionnaire was delivered via Google Forms and disseminated using a link in an invitation email sent to the participants. RESULTS: A total of 13 consultant responses (response rate of 81%) and 12 trainee responses (response rate of 92%) were received. Of these, three consultants and five trainees were using IR at the time of the study. Several themes emerged highlighting the perceived benefits and concerns regarding IR. CONCLUSIONS: This study suggests that there is a disparity in the way IR is used in OMFP training across the UK. There was shared concern between consultants and trainees regarding the lack of clear guidance and subsequent fear of litigation. These are issues that need to be addressed if trainees are to have a similar experience across the country and be prepared for independent practice on completion of training.

Guidelines for cellular and molecular pathology content in clinical trial protocols: the SPIRIT-Path extension.

The 2013 SPIRIT (Standard Protocol Items: Recommendations for Interventional Trials) Statement provides evidence-based recommendations for the minimum content to be included in a clinical trial protocol. Assessment of biospecimens is often required for trial eligibility or as part of an outcome evaluation, and precision molecular approaches are increasingly used in trial design. However, cellular and molecular pathology practices within trials have not been codified or formalised. We developed international consensus reporting guidelines for cellular and molecular pathology content in clinical trial protocols (the SPIRIT-Path extension) using an international Delphi process, which assesses candidate items generated from a previous systematic review, followed by an expert consensus meeting. 74 individuals from five continents responded, including clinicians, statisticians, laboratory scientists, patient advocates, funders, industry representatives, journal editors, and regulators. The SPIRIT-Path guidelines recommend 14 additional items (seven extensions to the SPIRIT checklist and seven elaborations) that should be addressed in trial protocols containing pathology content, alongside the SPIRIT 2013 Statement items. SPIRIT-Path recommends that protocols should document the individuals, processes, and standards for all cellular and molecular pathology components of the trial, including all stages of the specimen pathway and any digital pathology methods, with specific consideration of the value of trial data and biological tissues for additional translational studies.

Delphi study to determine the key qualities consultant histopathologists look for in their trainees.

AIMS: A Delphi study to triangulate and determine the relative importance of the key qualities of trainees identified from qualitative interviews that sought to understand how consultant histopathologists determine diagnostic competences in trainees. METHODS: Twelve participants were purposively chosen for the Delphi to form an expert panel of relevant stakeholders. Participants were asked to score and rank the items presented to them. RESULTS: A total of 22 out of 27 of the key qualities of trainees (items) reached 'consensus in' after round 2 suggesting participants were able to agree that the majority of the items identified in the qualitative interviews were important to diagnostic competence. Five items reached 'no consensus'. Participants did not suggest any additional items. Participants particularly valued qualities of reflection and professionalism and trainees who understood the process of reaching a diagnosis and how their pathological report could impact on patient care. CONCLUSIONS: This study has triangulated findings from our qualitative interviews and show that consultants value a wide variety of qualities when determining diagnostic competence in their trainees. The judgement is complex and is therefore best assessed longitudinally and on a number of cases, so consultants can look for consistency of both approach to diagnosis and of trainee behaviour.

How consultants determine diagnostic competence in histopathology trainees.

AIMS: This is a qualitative study exploring how consultant histopathologists determine diagnostic competence in their trainees. METHODS: Semi-structured interviews were conducted with consultants and trainees and analysed using the Framework Method. RESULTS: Five major themes emerged from the data: process, person, stage of training, trust and time. Within these major themes, there were multiple subthemes which reflect the complex, longitudinal nature of the judgement, as well as the knowledge, skills and attitudes which are most relevant to diagnostic competence. A conceptual framework is proposed to illustrate the judgement ecology, which is supported by anonymised quotes from interview participants. CONCLUSIONS: Our study is the first to explore in depth how consultant histopathologists determine diagnostic competence in their trainees. This is particularly important as histopathology is a unique medical specialty for which there is little evidence to support the current assessment strategies during training. The resulting conceptual model and findings from this study may help to form an evidence base to inform future assessment tools in histopathology.

Lumps and Bumps of the Gingiva: A Pathological Miscellany.

Lesions of the gingivae are amongst the commonest lesions seen in patients and the vast majority are reactive hyperplasias, related to a number of chronic irritant stimuli. However, there are a number of entities that have a predilection for the gingivae, which are much less common in other parts of the oral cavity. The purpose of this paper is to discuss the clinical and histological differential diagnoses when presented with a lump on the gingivae, including the approach to diagnosis and diagnostic pitfalls.

Odontogenic tumors and lesions treated in a single specialist oral and maxillofacial pathology unit in the United Kingdom in 1992-2016.

OBJECTIVES: Odontogenic tumors (ODTs) are a heterogeneous group of lesions derived from elements of tooth-forming tissues. No detailed data on the incidence of odontogenic tumors in the United Kingdom have been published. The aim of this study was to retrospectively describe the range and incidence of odontogenic tumors from 1992 to 2016 in a single specialist unit and to compare this population with others. STUDY DESIGN: By using the Oral and Maxillofacial Pathology database, Sheffield (UK), we included both local and referred consultation cases. A proportion of diagnoses were reclassified in accordance with the 2017 World Health Organization classification. RESULTS: In total, 559 odontogenic tumors were diagnosed. Overall, the most common lesions were ameloblastoma (196 [33.8%]), odontoma (148 [25.5%]), and odontogenic myxoma (37 [6.3%]), but this varied between local and referral case populations, with odontomas being most common in the local population (43%). The sites affected and the gender and age of patients were similar to other Western populations. Malignant ODTs comprised 33 cases (5.7%), of which 9 (27.3%) were ameloblastic carcinoma. The majority of the malignant ODTs comprised referral cases. CONCLUSIONS: Here, we present the first detailed data on ODTs within a UK population, and the pattern of incidence from the local population is similar to other Western populations. The exceptional rarity of malignant ODTs emphasizes the need for specialist centers for their treatment to gain diagnostic experience.

Assessors' and trainees' perceptions of workplace-based assessments in histopathology.

AIM: Workplace-based assessments (WBAs) are an integral part of specialist medical and dental training in the UK. Histopathology represents a very different training environment to the surgical specialities so it is important to know that the current WBAs are fit for purpose. A literature search revealed very little evidence regarding the perception of WBAs in histopathology. The aim of this study was therefore to assess the current perception of WBAs in histopathology by assessors and trainees. METHODS: A questionnaire was sent to all histopathology assessors and trainees on the Royal College of Pathologists database. Data were analysed using basic descriptive statistics. Free text comments were analysed by thematic analysis. RESULTS: The questionnaire was completed by 242/2175 assessors (response rate 11.1%) and 91/519 trainees (response rate 17.5%). There was no significantly different perception of WBAs between trainers and trainees (p>0.05). Key findings included respondents stating that they strongly disagreed or disagreed WBAs identify diagnostic competence (68% of trainees; 62% of assessors), identify trainees in difficulty (69% of trainees; 64% of assessors) or accurately reflect trainee progress (62% of trainees; 59% of assessors). Analysis of free text comments identified three main issues related to WBAs: their utilisation, purpose and design. CONCLUSION: There was an overall negative perception of WBAs, particularly their perceived regulatory nature. It appears that the current WBAs do not always meet the criteria of a useful test in that they are perceived as being applied variably, produce results with questionable validity and have little apparent educational value.

A review of paediatric oral and maxillofacial pathology.

This review aims to summarise common paediatric oral and maxillofacial pathology. It will focus on lesions that have a particular predilection for children, lesions that impart significant morbidity or rare and important entities which paediatric specialists may be less familiar with. Although the vast majority of pathology encountered will be benign or require minimal intervention, there are also lesions that may require urgent referral to an appropriate specialist, multidisciplinary team care and significant surgery. Recognition and appreciation of the clinicopathological features should facilitate an appreciation that the growth, anatomy, physiology or relationship of the maxillofacial structures may have been altered by the pathological entity or treatment received.
