Re-evaluation of the methodology for estimating the US specialty physician workforce.

Increasing pursuit of subspecialized training has quietly revolutionized physician training, but the potential impact on physician workforce estimates has not previously been recognized. The Physicians Specialty Data Reports of the Association of American Medical Colleges, derived from specialty designations in the American Medical Association (AMA) Physician Professional Data (PPD), are the reference source for US physician workforce estimates; by 2020, the report for pathologists was an undercount of 39% when compared with the PPD. Most of the difference was due to the omission of pathology subspecialty designations.

An Update on Prenatal Diethylstilbestrol Exposure and High-Grade Squamous Intraepithelial Lesions of the Lower Genital Tract.

Women with prenatal diethylstilbestrol exposure are excluded from less frequent cervical cancer screening because of their increased neoplasia risk. We report the results of a prospective follow-up study of prenatal diethylstilbestrol exposure and lower genital tract high-grade (grade 2 or higher) squamous intraepithelial lesions (HSIL). The age-adjusted risk of HSIL among diethylstilbestrol-exposed women (n=4,062) was higher than among the diethylstilbestrol unexposed (n=1,837) through age 44 years (hazard ratio 2.

Features of burnout amongst pathologists: A reassessment.

There has been little rigorous assessment of burnout among pathologists and pathology trainees. Given this relative dearth of relevant literature on pathologist burnout, this report aims to raise awareness of the issue among those working in and around this specialty. Our results are based on a survey given in conjunction with the American Board of Pathology's (ABPath) biennial Continuing Certification (CC) reporting of activities required of diplomates to maintain certification.

Strong Job Market for Pathologists: Results From the 2021 College of American Pathologists Practice Leader Survey.

Context.—: There has long been debate about whether and when there may be a shortage of pathologists in the United States. One way to assess this is to survey the hiring experiences of pathology practices.

Evidence-Based Alignment of Pathology Residency With Practice II: Findings and Implications.

This article presents findings from a 4-year series of surveys of new-in-practice pathologists, and a survey of physician employers of new pathologists, assessing how pathology graduate medical education prepares its graduates for practice. Using the methodology described in our previous study, we develop evidence for the importance of residency training for various practice areas, comparing findings over different practice settings, sizes, and lengths of time in practice. The principal findings are (1) while new-in-practice pathologists and their employers report residency generally prepared them well for practice, some areas-billing and coding, laboratory management, molecular pathology, and pathology informatics-consistently were identified as being important in practice but inadequately prepared for in residency; (2) other areas-autopsy pathology, and subspecialized apheresis and blood donor center blood banking services-consistently were identified as relatively unimportant in practice and excessively prepared for in residency; (3) the notion of a single comprehensive model for categorical training in residency is challenged by the disparity between broad general practice in some settings and narrower subspecialty practice in others; and (4) the need for preparation in some areas evolves during practice, raising questions about the appropriate mode and circumstance for training in these areas.

Polycarbonate Urethane Mesh: A New Material for Pelvic Reconstruction.

Objective: Polycarbonate urethane (PCU) is a new biomaterial, and its mechanical properties can be tailored to match that of vaginal tissue. We aimed to determine whether vaginal host immune and extracellular matrix responses differ after PCU versus lightweight polypropylene (PP) mesh implantation.

Methods: Hysterectomy and ovariectomy were performed on 24 Sprague-Dawley rats.

Evaluation of Host Immune Cellular and Extracellular Matrix Responses to Prolapse Mesh With and Without Tension in a Rat Model.

Objectives: We sought to determine whether vaginal host immune cellular and extracellular matrix responses are altered in a rat sacrocolpopexy model when lightweight polypropylene mesh is attached on tension versus without tension.

Methods: We performed hysterectomy and ovariectomy in 32 Sprague-Dawley rats. Animals were assigned to 4 groups (n = 8/group): (1) controls with sham operation only (control), (2) mesh sutured only on the vagina (vaginal mesh), (3) sacrocolpopexy without tension, and (4) sacrocolpopexy with tension.

Social Media Engagement at Academic Conferences: Report of the Association of Pathology Chairs 2018 and 2019 Annual Meeting Social Media Committee.

The use of social media at academic conferences is expanding, and platforms such as Twitter are used to share meeting content with the world. Pathology conferences are no exception, and recently, pathology organizations have promoted social media as a way to enhance meeting exposure. A social media committee was formed ad hoc to implement strategies to enhance social media involvement and coverage at the 2018 and 2019 annual meetings of the Association of Pathology Chairs.

Reevaluation of the US Pathologist Workforce Size.

Importance: There is currently no national organization that publishes its data that serves as the authoritative source of the pathologist workforce in the US. Accurate physician numbers are needed to plan for future health care service requirements.

Objective: To assess the accuracy of current pathologist workforce estimates in the US by examining why divergency appears in different published resources.

The State of the Job Market for Pathologists: Evidence From the College of American Pathologists Practice Leader Survey.

Context.—: Disagreement exists within the pathology community about the status of the job market for pathologists. Although many agree that jobs in pathology were harder to come by earlier this decade, recent evidence suggests improvement is occurring.

Whole-Genome and Segmental Homozygosity Confirm Errors in Meiosis as Etiology of Struma Ovarii.

Strumae ovarii are neoplasms composed of normal-appearing thyroid tissue that occur within the ovary and rarely spread to extraovarian sites. A unique case of struma ovarii with widespread dissemination detected 48 years after removal of a pelvic dermoid provided the opportunity to reexamine the molecular nature of this form of neoplasm. One tumor, from the heart, consisting of benign thyroid tissue was found to have whole-genome homozygosity.

Reproductive tract biology: Of mice and men.

The study of male and female reproductive tract development requires expertise in two separate disciplines, developmental biology and endocrinology. For ease of experimentation and economy, the mouse has been used extensively as a model for human development and pathogenesis, and for the most part similarities in developmental processes and hormone action provide ample justification for the relevance of mouse models for human reproductive tract development. Indeed, there are many examples describing the phenotype of human genetic disorders that have a reasonably comparable phenotype in mice, attesting to the congruence between mouse and human development.

The Life Cycle of the Uterine Fibroid Myocyte.

Purpose Of Review: Uterine fibroids are common benign tumors of women in the USA and worldwide, yet the biological nature and pathogenesis of these tumors remain largely unknown. This review presents our view of the stages in the life cycle of a subset of uterine fibroid myocytes, introduces hypothetical concepts and morphological data to explain these changes, and relates these changes in individual myocytes to the phases of fibroid tumor development.

Recent Findings: The observations gained from light and electron microscopic, immunohistochemical, and morphometric studies in our laboratory have led to the hypothesis that fibroid changes over time may relate to the excessive production of collagen by phenotypically transformed myocytes.

Development of the human female reproductive tract.

Development of the human female reproductive tract is reviewed from the ambisexual stage to advanced development of the uterine tube, uterine corpus, uterine cervix and vagina at 22 weeks. Historically this topic has been under-represented in the literature, and for the most part is based upon hematoxylin and eosin stained sections. Recent immunohistochemical studies for PAX2 (reactive with Müllerian epithelium) and FOXA1 (reactive with urogenital sinus epithelium and its known pelvic derivatives) shed light on an age-old debate on the derivation of vaginal epithelium supporting the idea that human vaginal epithelium derives solely from urogenital sinus epithelium.

Evidence-Based Alignment of Pathology Residency With Practice: Methodology and General Consideration of Results.

Few medical specialties engage in ongoing, organized data collection to assess how graduate medical education in their disciplines align with practice. Pathology educators, the American Board of Pathology, and major pathology organizations undertook an evidence-based, empirical assessment of what all pathologists need to learn in categorical residency. Two challenges were known when we commenced and we encountered 2 others during the project; all were ultimately satisfactorily addressed.

Tissue interactions and estrogenic response during human female fetal reproductive tract development.

The role of tissue interactions was explored to determine whether epithelial differentiation within the developing human reproductive tract is induced and specified by mesenchyme in tissue recombinants composed of mouse vaginal mesenchyme + human uterine tubal epithelium (mVgM+hTubE). The tissue recombinants were grown in DES-treated ovariectomized athymic mice. After 2-4 weeks of in vivo growth, several vaginal specific features were expressed in the human tubal epithelium.

A Review and Update on Papillary Immature Metaplasia of the Uterine Cervix: A Distinct Subset of Low-Grade Squamous Intraepithelial Lesion, Proposing a Possible Cell of Origin.

Context: - Papillary immature metaplasia (PIM) is a known papillary cervical lesion associated with low-risk human papillomavirus (LR-HPV).

Objective: - To evaluate additional clinicopathologic features and the HPV genotypes of PIM and discuss the presumptive cell of origin.

Design: - A total of 26 PIM cases were evaluated by p16, cytokeratin (CK) 7, and CK17 immunohistochemical stainings.

Prenatal diethylstilbestrol exposure and cancer risk in women.

In the Diethylstilbestrol [DES] Combined Cohort Follow-up, the age- and calendar-year specific standardized incidence ratio [SIR] for clear cell adenocarcinoma [CCA] was 27.6 (95% confidence interval [CI] 7.51-70.

Response of xenografts of developing human female reproductive tracts to the synthetic estrogen, diethylstilbestrol.

Human female fetal reproductive tracts 9.5-22 weeks of gestation were grown for 1 month in ovariectomized athymic adult female mouse hosts that were either untreated or treated continuously with diethylstilbestrol (DES) via subcutaneous pellet. Normal morphogenesis and normal patterns of differentiation marker expression (KRT6, KRT7, KRT8, KRT10, KRT14, KRT19, ESR1, PGR, TP63, RUNX1, ISL1, HOXA11 and α-ACT2) were observed in xenografts grown in untreated hosts and mimicked observations of previously reported (Cunha et al.

New insights into human female reproductive tract development.

We present a detailed review of the embryonic and fetal development of the human female reproductive tract utilizing specimens from the 5th through the 22nd gestational week. Hematoxylin and eosin (H&E) as well as immunohistochemical stains were used to study the development of the human uterine tube, endometrium, myometrium, uterine cervix and vagina. Our study revisits and updates the classical reports of Koff (1933) and Bulmer (1957) and presents new data on development of human vaginal epithelium.

Structured Annual Faculty Review Program Accelerates Professional Development and Promotion: Long-Term Experience of the Duke University Medical Center's Pathology Department.

This retrospective observational study on faculty development analyzes the Duke University Pathology Department's 18-year experience with a structured mentoring program involving 51 junior faculty members. The majority had MD degrees only (55%). The percentage of young women faculty hires before 1998 was 25%, increasing to 72% after 2005.

Prenatal diethylstilbestrol exposure and high-grade squamous cell neoplasia of the lower genital tract.

Background: Prenatal diethylstilbestrol (DES) exposure is associated with an excess risk of clear-cell adenocarcinoma of the vagina and cervix, and of high-grade squamous neoplasia.

Objective: We explored whether neoplasia risk remains elevated among DES-exposed women as they age.

Study Design: In all, 4062 DES-exposed and 1837 unexposed daughters were followed for approximately 30 years (1982 through 2013) for pathology-confirmed diagnoses of cervical intraepithelial neoplasia grade ≥2 (CIN2+) of the lower genital tract (n = 178).
