Factors influencing US osteopathic medical students to choose pathology as a specialty.

The decline in the number of US allopathic (Medical Doctor or M.D.) medical students matching to pathology residency has been a topic of much discussion at national pathology professional society meetings and in recent publications. A recent survey of fourth-year allopathic medicals students was conducted to better understand the rationale behind students' interest or lack thereof in pathology as a specialty. This study utilizes a similar survey tool gauging osteopathic (Doctor of Osteopathy or D.O.) student knowledge and interest in pathology, and offers insight into a possible growth market for the specialty. Similar to allopathic students, osteopathic students noted that clinical or research opportunities in pathology during medical school, autopsy observation/participation, and participation in pathology interest groups correlated with a greater likelihood of selecting pathology as a specialty. However, some key differences in osteopathic medical school curricular elements including microscope use, gross pathology specimen demonstrations, case-based learning by pathologists, exposure to pathology during other rotations, awareness of a pathology interest group, as well as an overall understanding of the everyday work of a pathologist were noted. Experiential exposure to pathology, and direct mentorship from pathologists may present an opportunity for pathology professional organizations, and pathology residency programs to partner with osteopathic medical schools to increase interest in the field, and aid in pipeline development.

Positive Job Search Experience for New Pathologists Seeking First Employment Between 2017 and 2019.

CONTEXT.­: An aging population calls for an adequate response in the workforce of medical professionals. The field of pathology has seen a downward trend in numbers of graduating US allopathic medical students choosing the specialty. Concerns about the job market after residency and fellowship graduation may be a contributing factor. OBJECTIVE.­: To provide an update on the trends emerging from a survey of pathology graduates' job search experience for their first nonfellowship position. DESIGN.­: Data from an annual job search survey sent by the College of American Pathologists Graduate Medical Education Committee between 2017 and 2019 to College of American Pathologists junior members and fellows in practice 3 years or less actively looking for a nonfellowship position was analyzed. Various indicators of the job search experience were compared year to year and with the previously published 2012 to 2016 benchmark data. RESULTS.­: Analysis revealed positive trends between the 2017 to 2019 data and the 2012 to 2016 benchmark data, including participants' perceiving more ease in finding a position, improved availability of jobs in their subspecialty choice, and higher ratings of satisfaction with the position accepted, as well as a greater proportion of respondents finding a position within 6 months of initiating their job search. CONCLUSIONS.­: The job market for pathology residents and fellows looking for their first nonfellowship position has improved with respect to multiple indicators, such as ease of finding a position, length of job search, and satisfaction with the position accepted when comparing 2017 to 2019 data with the 2012 to 2016 benchmark data.

Entry of Graduates of US Pathology Residency Programs Into the Workforce: Cohort Data Between 2008 and 2016 Remain Positive and Stable.

The pathologist workforce in the United States is a topic of interest to the health-care community as a whole and to institutions responsible for the training of new pathologists in particular. Although a pathologist shortage has been projected, there has been a pervasive belief by medical students and their advisors that there are "no jobs in pathology." In 2013 and again in 2017, the Program Directors Section of the Association of Pathology Chairs conducted surveys asking pathology residency directors to report the employment status of each of their residents graduating in the previous 5 years. The 2013 Program Directors Section survey indicated that 92% of those graduating in 2010 had obtained employment within 3 years, and 94% of residents graduating in 2008 obtained employment within 5 years. The 2017 survey indicated that 96% of those graduating in 2014 had obtained employment in 3 years, and 97% of residents graduating in 2012 obtained positions within 5 years. These findings are consistent with residents doing 1 or 2 years of fellowship before obtaining employment. Stratification of the data by regions of the country or by the size of the residency programs does not show large differences. The data also indicate a high percentage of employment for graduates of pathology residency programs and a stable job market over the years covered by the surveys.

Gender Parity in Gainful Employment and Other Gender Trends in the Job Market for Recent Pathology Graduates.

CONTEXT.­: Gender-based barriers to equal salary, career advancement, and leadership still exist in medicine. Herein we provide the first report of data comparing the experiences of men and women seeking their first nonfellowship position in pathology. OBJECTIVE.­: To identify gender trends regarding pathologists taking their first job after training and the relationship to various demographic factors, job search satisfaction, and outcome. DESIGN.­: Aggregate data from the College of American Pathologists Graduate Medical Education Committee Job Market surveys (2015-2018) were analyzed across multiple domains including residency focus, number and subspecialty of fellowships completed, and extent to which expectations were met in regard to work duties, geographic preference, benefits, and salary. These data were examined in the context of assessing gender-based differences. RESULTS.­: Comparable results were identified in all measured outcomes according to gender. There were no differences between gender and medical school type, relocation, residency training focus, number of fellowships completed, overall satisfaction with position accepted, salary, or extent to which the position met expectations. Similarly, there were also no discrepancies between gender and the geographic region in which positions were accepted, practice setting, practice subspecialty, partnership track, length of job search, or difficulty finding a position. CONCLUSIONS.­: Analysis from 4 years of job market survey data shows equivalent results between men and women looking for their first nonfellowship position in pathology. There were no significant differences with regard to difficulty finding a position, overall satisfaction with the position accepted, salary, benefits, or access to partnership track.

Will I Need to Move to Get My First Job?: Geographic Relocation and Other Trends in the Pathology Job Market.

CONTEXT.­: There is an ongoing perception that the pathology job market is poor, which may be discouraging medical students from pursuing the specialty. Academic pathologists believe that jobs are available but relocation may be necessary. OBJECTIVE.­: To identify trends regarding the geographic relocation of pathologists taking their first job after training. DESIGN.­: The College of American Pathologists (CAP) Graduate Medical Education Committee has sent an annual job search survey from 2012-2016 to CAP junior members and fellows in practice for 3 years or less and seeking their first job. Data were analyzed across demographics and geographic domains consisting of the following: stayed at same institution/city, relocated within the same region, or relocated to a different region. Standard statistical methods were used. RESULTS.­: Of 501 respondents, 421 reported completing combined anatomic pathology (AP)/clinical pathology (CP) training, while 80 reported AP- or CP-only training. Of the 421 AP/CP respondents, 109 (26%) stayed at the same institution or city, while of the 80 AP- or CP-only respondents, 36 (45%) stayed at the same institution or city. One hundred ninety-nine respondents completed surgical pathology fellowships with 124 (62%) general/oncologic surgical pathology and 75 (38%) subspecialty surgical pathology trainees. Job seekers who completed general surgical pathology/surgical oncologic pathology fellowship accounted for 34 of 52 (65%) of those remaining at the same institution or city, while those with subspecialty training accounted for 40 of 77 (52%) of those relocating to a different region. Relocation did not demonstrate any significant trends in regard to other demographics studied. CONCLUSIONS.­: The pathology job market appears stable with no precedent for geographic hardship.

Randomized, controlled trial of standard, large-capacity versus jumbo biopsy forceps for polypectomy of small, sessile, colorectal polyps.

BACKGROUND: Polypectomy with cold biopsy forceps is a frequently used technique for removal of small, sessile, colorectal polyps. Jumbo forceps may lead to more effective polypectomy because of the larger size of the forceps cup. OBJECTIVE: To evaluate the efficiency of cold jumbo biopsy forceps compared with standard forceps for polypectomy of small, sessile, colorectal polyps. DESIGN: Randomized, controlled trial. SETTING: Outpatient endoscopy center. PATIENTS: This study involved 140 patients found to have at least one eligible polyp defined as a sessile polyp measuring ≤6 mm. INTERVENTION: Polypectomy with cold biopsy forceps. MAIN OUTCOME MEASUREMENTS: Complete visual polyp eradication with one forceps bite. RESULTS: In 140 patients, a total of 305 eligible polyps were detected (151 removed with jumbo forceps and 154 with standard forceps). Complete visual eradication of the polyp with one forceps bite was achieved in 78.8% of the jumbo forceps group and 50.7% of the standard forceps group (P < .0001). Biopsies from the polypectomy sites of adenomatous polyps thought to be visually completely eradicated with one bite showed a trend toward a higher complete histologic eradication rate with the jumbo forceps (82.4%) compared with the standard forceps (77.4%), but the difference did not reach statistical significance (P = .62). The withdrawal time for visual inspection of the colon and time to perform polypectomies were significantly shorter in the jumbo forceps group (mean 21.43 vs 18.23 minutes; P = .02). LIMITATIONS: Lack of blinding to the type of forceps used. CONCLUSION: The jumbo biopsy forceps is superior to the standard forceps in removing small, sessile polyps. ( CLINICAL TRIAL REGISTRATION NUMBER: NCT00855790.).

Autoimmune esophagitis: IgG4-related tumors of the esophagus.

We present a case of a 23-year-old gentleman who presented with dysphagia, weight loss, and recurrent esophageal strictures requiring multiple dilatations. An endoscopic ultrasound with esophagogastroduodenoscopy revealed a mass present in the distal esophagus. Fine needle aspiration suggested that the mass in the lower esophagus resembled a gastrointestinal stromal tumor. After surgical resection, final pathologic analysis revealed that the tumor was comprised of benign-appearing fibroinflammatory cells with an increase and predominance of IgG4-positive plasma cells. The microscopic appearance was consistent with a benign condition as a result of an IgG4-related process. He did not, however, have any other symptoms indicative of systemic autoimmune disease or connective tissue disorders. We present the pre-operative imaging, operative management, pathologic diagnosis, and literature review of this rare condition and the first known report of autoimmune esophagitis as part of the IgG4 spectrum of diseases.

Isolated lymphoplasmacytic sclerosing pancreatitis involving the pancreatic tail.

We present an interesting case of a 62-year-old woman with a 3-month history of vague, left-sided abdominal pain. CT imaging revealed a hypodense lesion in the tail of the pancreas. The patient had no history of pancreatitis or autoimmune diseases. Laboratory testing revealed a normal CA19-9 (33 U/mL) and an elevated IgG4 (133 mg/dL). Due to concerns of pancreatic malignancy, she underwent operation. We found a dense, inflammatory mass in the tail of the pancreas, which was removed via an open distal pancreatectomy with splenectomy. Histologic analysis revealed a pancreas with sclerotic ducts and surrounding lymphoplasmacytic inflammation most consistent with lymphoplasmacytic sclerosing pancreatitis (LPSP). LPSP, also termed autoimmune pancreatitis, is a benign disease of the pancreas, which can mimic pancreatic adenocarcinoma. It is the most common benign finding diagnosed on pathology after pancreatic resection for presumed malignancy. LPSP most commonly involves the head and, more uncommonly, the tail of the pancreas. It can be successfully treated with steroids obviating the need for resection. IgG4 levels may assist in recognition of this disease. As our experience with utilization of IgG4 testing and knowledge of the systemic nature of LPSP increase, patients with this disease may be spared unnecessary resection.

Autoimmune pancreatitis and concurrent small lymphocytic lymphoma: not just a coincidence?

CASE: A 76-year-old gentleman presented with painless jaundice, weight loss, and anorexia. Computed tomography imaging revealed fullness of the pancreatic head and multiple enlarged retroperitoneal lymph nodes. Cholangiogram revealed a distal common bile duct stricture. Due to concerns of malignancy, the patient underwent operative exploration. Several enlarged lymph nodes in the aortocaval region and a firm hard mass in the pancreatic head were found. Frozen section from one of the lymph nodes was suspicious for low-grade lymphoma. A pancreaticoduodenectomy was performed. Histologic analysis of the pancreatic head revealed a lymphoplasmacytic infiltrate with stromal fibrosis consistent with autoimmune pancreatitis. The retroperitoneal lymph nodes were involved by small lymphocytic lymphoma. DISCUSSION: Autoimmune pancreatitis is the most common benign diagnosis after pancreatic resection for presumed malignancy. It has a well-documented association with autoimmune conditions, such as Sjögren's syndrome, inflammatory bowel disease, and sclerosing cholangitis. Additionally, chronic lymphocytic leukemia-small lymphocytic lymphoma is often associated with autoimmune phenomena, most notably autoimmune hemolytic anemia. However, an association between autoimmune pancreatitis and small lymphocytic lymphoma has not been previously described. To our knowledge, this is the first reported case of a patient with concurrent autoimmune pancreatitis and small lymphocytic lymphoma.

Contemporary results with ampullectomy for 29 "benign" neoplasms of the ampulla.

BACKGROUND: Ampullectomy may be an appropriate oncologic procedure in selected patients. Sparse data exist on procedure-related complications and the relationship between histologic analysis and outcomes. STUDY DESIGN: We retrospectively reviewed our experience with ampullectomy in 29 patients with a preoperative benign histologic diagnosis over 15 years (1991 to 2006). Presenting signs, symptoms, and preoperative diagnostic studies were reviewed. Postoperative complications and followup for recurrence were recorded. The abilities of preoperative histologic biopsy, intraoperative frozen section, and final histologic analysis to guide management and predict outcomes were determined. RESULTS: Median age was 63 years. Jaundice was present in 30% of patients. Median length of hospital stay was 9 days. Forty-five percent of patients had a complication, and there was one postoperative mortality (3%). Ampullary adenomatous neoplasms were present in 89% of patients. Preoperative biopsy had complete concordance with final pathology in 76% of patients. Preoperative biopsy and intraoperative frozen section failed to identify carcinoma in four patients. Pancreaticoduodenectomy was performed within 7 days in the postoperative period in three of these patients. After ampullectomy (median followup=16 months), recurrences were identified in two patients (8%) with benign tumors. No patients with high-grade dysplasia (n=4) have had recurrence. CONCLUSIONS: Preoperative biopsy and intraoperative frozen section analysis have limitations in the management of patients undergoing ampullectomy. High-grade dysplasia on preoperative biopsy is not an absolute contraindication to ampullectomy. Morbidity of ampullectomy is significant, but longterm outcomes of this procedure, in patients without invasive malignancy, are acceptable.

Elevation of serum IgG4 in Western patients with autoimmune sclerosing pancreatocholangitis: a word of caution.

BACKGROUND: Autoimmune pancreatocholangitis is characterized by sclerosing inflammation of the biliary tree or pancreatic duct and can mimic pancreaticobiliary malignancy. Serum immunoglobin (Ig) G4 values seem to be helpful in distinguishing autoimmune pancreatocholangitis from pancreatic malignancy in the Japanese population; however, its significance in the Western population has not been well studied. METHODS: We report a retrospective analysis of 7 consecutive patients with autoimmune pancreatocholangitis and compare them to 23 patients with pancreatic malignancy. Clinical presentation, diagnostic tests, and preoperative IgG4 levels were reviewed in all patients. Presence of autoimmune pancreatocholangitis or pancreatic malignancy was determined by pathologic analysis in all patients and reviewed by a single pathologist. RESULTS: In all patients, autoimmune pancreatocholangitis manifested in a similar fashion to pancreatic malignancy. Median IgG4 levels were far lower in pancreatic cancer patients with localized, resectable disease (24 mg/dL), locally advanced disease (24 mg/dL), and metastatic disease (28 mg/dL) as compared with patients with autoimmune pancreatocholangitis (142 mg/dL, P < .05). Only one patient with pancreatic cancer had an IgG4 level that was >100 mg/dL. In contrast, all patients with autoimmune pancreatitis or cholangitis had levels >100 mg/dL. However, in five of these seven patients, IgG4 levels were below the upper limits of normal. CONCLUSIONS: Autoimmune pancreatocholangitis mimics pancreatobiliary malignancy. Serum IgG4 values seem to be helpful in distinguishing autoimmune pancreatocholangitis from malignancy in the Western population. However, absolute values seem to be lower in the United States compared with Japan. The upper limit of normal as reported in laboratories in the United States may not be useful in identifying abnormally high IgG4 values. A new upper limit of normal may need to be defined because IgG subclass determinations are being used more frequently in Western patients with biliary obstruction.

Detection of endogenous biomolecules in Barrett's esophagus by Fourier transform infrared spectroscopy.

Fourier transform infrared (FTIR) spectroscopy provides a unique molecular fingerprint of tissue from endogenous sources of light absorption; however, specific molecular components of the overall FTIR signature of precancer have not been characterized. In attenuated total reflectance mode, infrared light penetrates only a few microns of the tissue surface, and the influence of water on the spectra can be minimized, allowing for the analyses of the molecular composition of tissues. Here, spectra were collected from 98 excised specimens of the distal esophagus, including 38 squamous, 38 intestinal metaplasia (Barrett's), and 22 gastric, obtained endoscopically from 32 patients. We show that DNA, protein, glycogen, and glycoprotein comprise the principal sources of infrared absorption in the 950- to 1,800-cm(-1) regime. The concentrations of these biomolecules can be quantified by using a partial least-squares fit and used to classify disease states with high sensitivity, specificity, and accuracy. Moreover, use of FTIR to detect premalignant (dysplastic) mucosa results in a sensitivity, specificity, positive predictive value, and total accuracy of 92%, 80%, 92%, and 89%, respectively, and leads to a better interobserver agreement between two gastrointestinal pathologists for dysplasia (kappa = 0.72) versus histology alone (kappa = 0.52). Here, we demonstrate that the concentration of specific biomolecules can be determined from the FTIR spectra collected in attenuated total reflectance mode and can be used for predicting the underlying histopathology, which will contribute to the early detection and rapid staging of many diseases.

Early histologic changes in fibrosing cholestatic hepatitis C.

Recurrent hepatitis C (RHCV) after liver transplantation is almost universal, and occasional patients will have an aggressive course characterized histologically by pericellular/sinusoidal fibrosis and cholestasis, known as fibrosing cholestatic hepatitis (FCH). The early stages and evolution of this disease have not been well characterized. A total of 77 liver biopsies performed for indication (nonprotocol) were evaluated for necroinflammation, rejection, cholestasis, and fibrosis. Control groups were composed of protocol biopsies from HCV transplant patients (10 biopsies) as well as non-HCV transplant patients (6 biopsies). Scoring for necroinflammation, rejection, and fibrosis were compiled using standard criteria (hepatic activity index, Banff, Ishak, METAVIR). Pericellular fibrosis was staged with a novel "sinusoidal" system. A cholestasis scoring system was developed to quantitate parenchymal and portal features of cholestasis. Biopsies were categorized as rejection, RHCV, FCH, and stable based on histology and clinical information. FCH was found to have a higher fibrosis stage overall when compared to most diagnostic groups, regardless of the staging system used. Additionally, sinusoidal fibrosis was significantly higher in the FCH diagnosis group. Cholestasis was more prominent in biopsies of FCH in all comparisons. In conclusion, the presence of cholestasis and fibrosis with mild to moderate RHCV should raise the suspicion of FCH. When studying the evolution of these cases, the first abnormality to appear is RHCV and cholestasis, fibrosis develops soon after, and both continue to worsen until the point of allograft failure or patient death.
