Using ThinPrep Papanicolaou test samples to evaluate sexually transmitted infection screening practices.

INTRODUCTION: We sought to evaluate the use of Papanicolaou samples as a screening tool for sexually transmitted infections (STIs). METHODS: Retrospective chart review analyzing Papanicolaou samples for STI. Samples were processed and results compared to clinical data to assess this technique's viability. Cases and controls were matched by sample date. Characteristics of women with STI testing were compared in bivariate analyses. RESULTS: We analyzed 50 STI-positive and 50 date-matched samples. Thirteen (26.0%) of the STI-positive patients were not screened at their visit. Women without STI screening were older (39.5 vs. 30.0 years, P = 0.001); non-Hispanic White (65.9% vs. 46.4%, P = 0.05); and married (60.0% vs. 26.9%, P = 0.005) than women with STI screening. Fifty-eight were offered and accepted STI testing at their visit; 37 samples were STI-positive: 17 (29.3%) Mycoplasma genitalium (Mgen), 10 (17.2%) chlamydia, 6 (10.3%) trichomoniasis, 1 (1.7%) gonorrhea, and 3 (5.2%) had two STIs. Among the 42 patients without STI testing, 12 (28.6%) had positive samples: 6 (14.3%) chlamydia, 5 (12.0%) Mgen, and 1 (2.4%) trichomoniasis. CONCLUSIONS: Over one-quarter of STI-positive patients were not screened; though low-risk by current screening criteria, a significant number may harbor untreated STIs; using Papanicolaou samples may allow for increased screening in this population.

The Prevalence of Extranodal Extension in Papillary Thyroid Cancer Based on the Size of the Metastatic Node: Adverse Histologic Features Are Not Limited to Larger Lymph Nodes.

Extranodal extension (ENE) is a prognostic indicator of aggressiveness for papillary thyroid cancer (PTC). The association between the size of metastatic nodes and the prevalence of ENE has not been previously explored. However, there is a common belief that small lymph nodes with metastatic disease do not significantly impact patient outcome. This study investigates the relationship between the prevalence of ENE and the size of a positive lymph node. Linear dimensions and malignant histological characteristics of 979 metastatic lymph nodes from 152 thyroid cancer patients were retrospectively analyzed. Data was analyzed using chi-square tests and multilevel logistic regression modeling. ENE was present in 144 of 979 lymph nodes; the sizes of the involved lymph nodes ranged from 0.9 to 44 mm. ENE was identified in 7.8% of lymph nodes measuring ≤ 5 mm, 18.9% between 6 and 10 mm, 23.1% between 11 and 15 mm, 25.0% between 16 and 20 mm, and 14.0% between 21 and 25 mm in size. The association between node size and ENE status was significant (odds ratio (OR) = 1.07, confidence interval (CI) = [1.04, 1.11]). The size of the metastatic focus directly correlated with ENE (OR = 1.07, 95% CI = [1.07, 1.14], p value < 0.001). Increasing lymph node size increases the likelihood of ENE for metastatic PTC. Importantly, small positive lymph nodes can also harbor ENE to a significant extent. Further studies are required to determine the clinical and prognostic significance of lymph node size and the presence of ENE.

Evaluation of ultrasound reporting for thyroid cancer diagnosis and surveillance.

BACKGROUND: Despite the importance of ultrasound imaging in thyroid disease care, ultrasound reports vary greatly in the features described. It is essential that ultrasound reports contain and present all components necessary for a clinical decision in a reader-friendly format. METHODS: One hundred ninety thyroid and neck ultrasound reports were scored using the universal ultrasound report template developed by Su et al, along with the American Thyroid Association (ATA) and the American Association of Clinical Endocrinologists/Associazione Medici Endocrinologi/European Thyroid Association (AACE/AME/ETA) guidelines. All ultrasounds were performed on patients seen between August and November 2015 by a single surgeon (M.L.U), and originated from a variety of physicians and institutions. RESULTS: An average of 30.9% of Su et al's criteria was satisfactorily included in the reports. Similar results were reached when the ATA and the AACE/AME/ETA guidelines were applied as scoring templates. CONCLUSION: Our results reveal the wide variation in ultrasound reporting. The standardization of ultrasound reporting would help to improve physicians' ability to properly diagnose and manage patients with thyroid disease.

Leiomyoma of the sternothyroid muscle.

BACKGROUND: Leiomyomas are benign cutaneous tumors of smooth muscle origin. Only a small percentage of leiomyomas arise in the head and neck region. We present the first case of leiomyoma arising in the sternothyroid muscle of the neck. CASE REPORT: We analyze the clinical presentation, pathology, and histology for a single case study. The histologic findings of the tumor located in the sternothyroid muscle support the diagnosis of leiomyoma. DISCUSSION: This is the first case of leiomyoma arising in the sternothyroid muscle, and only the second reported case of leiomyoma in the strap muscles of the neck. CONCLUSION: Leiomyoma should be included in the differential diagnosis of soft tissue tumors in the head and neck region. A histological analysis is essential in determining both tumor type and subtype, which will inform the proper course of treatment.

Improving the adoption of thyroid cancer clinical practice guidelines.

OBJECTIVES/HYPOTHESIS: To present an overview of the barriers to the implementation of clinical practice guidelines (CPGs) in thyroid cancer management and to introduce a computer-based clinical support system. DATA SOURCES: PubMed. REVIEW METHODS: A review of studies on adherence to CPGs was conducted. RESULTS: Awareness and adoption of CPGs is low in thyroid cancer management. Barriers to implementation include unfamiliarity with the CPGs and financial concerns. Effective interventions to improve adherence are possible, especially when they are readily accessible at the point of care delivery. Computerized clinical support systems show particular promise. The authors introduce the clinical decision making modules (CDMMs) of the Thyroid Cancer Care Collaborative, a thyroid cancer-specific electronic health record. These computer-based modules can assist clinicians with implementation of these recommendations in clinical practice. CONCLUSION: Computer-based support systems can help clinicians understand and adopt the thyroid cancer CPGs. By integrating patient characteristics and guidelines at the point of care delivery, the CDMMs can improve adherence to the guidelines and help clinicians provide high-quality, evidence-based, and individualized patient care in the management of differentiated thyroid cancer.

Inter-Observer Variation in the Pathologic Identification of Extranodal Extension in Nodal Metastasis from Papillary Thyroid Carcinoma.

BACKGROUND: Extranodal extension (ENE) in lymph node metastases has been shown to worsen the prognosis of papillary thyroid cancer (PTC). Despite the clinical significance of ENE, there are no stringent criteria for its microscopic diagnosis, and its identification is subject to inter-observer variability. The objective of this study was to determine the level of agreement among expert pathologists in the identification of ENE in PTC cases. METHODS: Eleven expert pathologists from the United States, Italy, and Canada were asked to review 61 scanned slides of representative permanent sections of PTC specimens from Mount Sinai Beth Israel Medical Center in New York. Each slide was evaluated for the presence of ENE. The pathologists were also asked to report the criteria they use to identify ENE. RESULTS: The overall strength of agreement in identifying ENE was only fair (κ = 0.35), and the proportion of observed agreement was 0.68. The proportions of observed agreement for the identification of perinodal structures (fat, nerve, skeletal, and thick-walled vessel involvement) ranged from 0.61 to 0.997. CONCLUSIONS: Overall agreement for the identification of ENE is poor. The lack of agreement results from both variation in pathologists' identification of features and disagreement on the histologic criteria for ENE. This lack of concordance may help explain some of the discordant information regarding prognosis in clinical studies when this feature is identified.

Testing with feedback improves recall of information in informed consent: A proof of concept study.

OBJECTIVE: This study investigates whether applying educational testing approaches to an informed consent video for a medical procedure can lead to greater recall of the information presented. METHODS: Undergraduate students (n=120) were randomly assigned to watch a 20-min video on informed consent under one of three conditions: 1) tested using multiple-choice knowledge questions and provided with feedback on their answers after each 5-min segment; 2) tested with multiple choice knowledge questions but not provided feedback after each segment; or 3) watched the video without knowledge testing. RESULTS: Participants who were tested and provided feedback had significantly greater information recall compared to those who were tested but not provided feedback and to those not tested. The effect of condition was stronger for moderately difficult questions versus easy questions. CONCLUSIONS: Inserting knowledge tests and providing feedback about the responses at timed intervals in videos can be effective in improving recall of information. PRACTICAL IMPLICATION: Providing informed consent information through a video not only standardizes the material, but using testing with feedback inserted within the video has the potential to increase recall and retention of this material.

Inter-Observer Variation in the Pathologic Identification of Minimal Extrathyroidal Extension in Papillary Thyroid Carcinoma.

BACKGROUND: Extrathyroidal extension (ETE) is a significant prognostic factor in papillary thyroid carcinoma (PTC). Minimal extrathyroidal extension (mETE) is characterized by involvement of the sternothyroid muscle or perithyroid soft tissue, and is generally identified by light microscope examination. Patients with mETE, identified pathologically, are automatically upstaged to pT3. However, the prognostic implications of mETE have been a source of controversy in the literature. Moreover, there is also controversy surrounding the identification of mETE on pathological specimens. The objective of this study was to determine the level of agreement among expert pathologists in the identification of mETE in PTC cases. METHODS: Eleven expert pathologists from the United States, Italy, and Canada were asked to perform a review of 69 scanned slides of representative permanent sections of PTC specimens. Each slide was evaluated for the presence of mETE. The pathologists were also asked to list the criteria they use to identify mETE. RESULTS: The overall strength of agreement for identifying mETE was slight (κ = 0.14). Inter-pathologist agreement was best for perithyroidal skeletal muscle involvement (κ = 0.46, moderate agreement) and worst for invasion around thick-walled vascular structures (κ = 0.02, slight agreement). In addition, there was disagreement over the constellation of histologic features that are diagnostic for mETE, which affected overall agreement for diagnosing mETE. CONCLUSIONS: Overall agreement for the identification of mETE is poor. Disagreement is a result of both variation in individual pathologists' interpretations of specimens and disagreement on the histologic criteria for mETE. Thus, the utility of mETE in staging and treatment of PTC is brought into question. The lack of concordance may explain the apparent lack of agreement regarding the prognostic significance of this pathologic feature.

ACTIVE SURVEILLANCE FOR PAPILLARY THYROID MICROCARCINOMA: NEW CHALLENGES AND OPPORTUNITIES FOR THE HEALTH CARE SYSTEM.

OBJECTIVE: The dramatic increase in papillary thyroid carcinoma (PTC) is primarily a result of early diagnosis of small cancers. Active surveillance is a promising management strategy for papillary thyroid microcarcinomas (PTMCs). However, as this management strategy gains traction in the U.S., it is imperative that patients and clinicians be properly educated, patients be followed for life, and appropriate tools be identified to implement the strategy. METHODS: We review previous active surveillance studies and the parameters used to identify patients who are good candidates for active surveillance. We also review some of the challenges to implementing active surveillance protocols in the U.S. and discuss how these might be addressed. RESULTS: Trials of active surveillance support nonsurgical management as a viable and safe management strategy. However, numerous challenges exist, including the need for adherence to protocols, education of patients and physicians, and awareness of the impact of this strategy on patient psychology and quality of life. The Thyroid Cancer Care Collaborative (TCCC) is a portable record keeping system that can manage a mobile patient population undergoing active surveillance. CONCLUSION: With proper patient selection, organization, and patient support, active surveillance has the potential to be a long-term management strategy for select patients with PTMC. In order to address the challenges and opportunities for this approach to be successfully implemented in the U.S., it will be necessary to consider psychological and quality of life, cultural differences, and the patient's clinical status.

Intraoral sebaceous carcinoma metastatic to the lung and subcutis: Case report and discussion of the literature.

BACKGROUND: Intraoral sebaceous carcinoma is a rare form of sebaceous carcinoma with only 9 published cases in the world literature to date. We present a 10th case of intraoral sebaceous carcinoma located in the anterior maxillary gingiva with metastases to the lung and subcutis and discuss 3 possible etiologies for this unique presentation. METHODS: We analyze the clinical presentation, pathology, histology, and genetic testing for a single case study and review relevant literature. RESULTS: The histologic findings of the lung tumor and surgical excisions of the tumors in the gingiva and subcutis suggest the gingiva is the primary site. There is no evidence for the genetic abnormalities consistent with Muir-Torre syndrome. CONCLUSION: The histologic findings suggest the oral cavity is the most likely site of tumor origin. This is the first case of intraoral sebaceous carcinoma reported to arise in the gingiva as well as to spread to cutaneous sites.

Oral cavity squamous cell carcinoma metastatic to central compartment (level 6) lymph nodes.

Alterations to drainage pathways in the head and neck as a result of surgical manipulation are not well understood. We present two unusual cases of oral squamous cell carcinoma metastatic to the level 6 nodal compartment following extensive treatment. Both oral squamous cell carcinoma cases exhibited metastases to the central neck compartment following extensive surgery and radiation. Each patient had prior history of multifocal oral cavity disease and recurrent neck metastases requiring salvage lymphadenectomy. Surgical interventions may alter the usual lymphatic drainage patterns. In cases of extensive treatment, all levels of the neck should be monitored for lymph node recurrence.

Health impact assessments for environmental restoration: the case of Caño Martín Peña.

BACKGROUND: Health Impact Assessment (HIA) is a methodology for predicting the effects of a proposed policy or plan on health. A proposed environmental restoration and development plan presented an opportunity for an HIA in an environmental justice community surrounding the Martín Peña channel in San Juan, Puerto Rico. The HIA focused on the dredging of the channel, debris removal, road, sewer, and storm water infrastructure improvements, housing demolition, and resident relocation. OBJECTIVE: The aim of this study was to determine the potential effects of the proposed plan on the community's health to inform the funding decision by the Puerto Rican legislature. As the first HIA in Puerto Rico, a secondary objective was to build HIA capacity in Puerto Rico. METHODS: This HIA used community training, literature reviews, existing local studies, focus groups, interviews, and disease surveillance data to assess baseline health, determine expected effects, and build capacity. FINDINGS: The Martín Peña community is experiencing deteriorating environmental conditions. Flooding and negative environmental exposures, such as mold, limits to physical activity, stress, chemical toxicants, pathogenic bacteria, and pests, are worsening. The higher rates of diseases, such as asthma and diarrhea, in the community compared with elsewhere in Puerto Rico appear to be largely attributable to these factors. Overall, the proposed plan is expected to improve many of these health disparities but the successful implementation depends on continued community acceptance and participation, particularly with the relocation process. Recommendations are for full financing and several mitigation efforts to avoid negative and preserve beneficial health consequences. CONCLUSIONS: As the first HIA in Puerto Rico, this assessment provided specific recommendations to benefit the health of the community affected by an environmental restoration and development plan and also capacity building for a larger audience in Puerto Rico. This approach could be generalized to other Latino environmental justice communities in Puerto Rico and abroad.
