Anomalies in the review process and interpretation of the evidence in the NICE guideline for chronic fatigue syndrome and myalgic encephalomyelitis.

Chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME) is a disabling long-term condition of unknown cause. The National Institute for Health and Care Excellence (NICE) published a guideline in 2021 that highlighted the seriousness of the condition, but also recommended that graded exercise therapy (GET) should not be used and cognitive-behavioural therapy should only be used to manage symptoms and reduce distress, not to aid recovery. This U-turn in recommendations from the previous 2007 guideline is controversial.We suggest that the controversy stems from anomalies in both processing and interpretation of the evidence by the NICE committee. The committee: (1) created a new definition of CFS/ME, which 'downgraded' the certainty of trial evidence; (2) omitted data from standard trial end points used to assess efficacy; (3) discounted trial data when assessing treatment harm in favour of lower quality surveys and qualitative studies; (4) minimised the importance of fatigue as an outcome; (5) did not use accepted practices to synthesise trial evidence adequately using GRADE (Grading of Recommendations, Assessment, Development and Evaluations trial evidence); (6) interpreted GET as mandating fixed increments of change when trials defined it as collaborative, negotiated and symptom dependent; (7) deviated from NICE recommendations of rehabilitation for related conditions, such as chronic primary pain and (8) recommended an energy management approach in the absence of supportive research evidence.We conclude that the dissonance between this and the previous guideline was the result of deviating from usual scientific standards of the NICE process. The consequences of this are that patients may be denied helpful treatments and therefore risk persistent ill health and disability.

COVID-19 Vaccine-Induced Parsonage-Turner Syndrome: A Case Report and Literature Review.

All modern vaccines share the risk of neurological adverse effects. Only a few cases of Parsonage-Turner syndrome (PTS), an uncommon peripheral nerve condition associated with coronavirus disease 2019 (COVID-19) immunization, have been reported to date. We describe a case of COVID-19 vaccine-induced PTS and provide a brief literature review. A 78-year-old male non-smoker with a medical history of coronary artery disease presented with non-exertional, constant chest pain for one hour and new onset of bilateral hand weakness for three days. He had no neurological disease or allergies and denied any recent trauma or infection. Three weeks before the onset of the symptoms, the patient received a second dose of the BNT162b2 COVID-19 vaccine, which was administered 21 days after the first dose. Physical examination was significant for weakness in right-hand grip and wrist flexion. There were no other motor deficits, upper motor neuron signs, bulbar weakness, or sensory deficits. Diagnostic workup for the underlying diabetes mellitus, infections, or other autoimmune diseases was negative. Imaging workup revealed no demyelination, fracture deformity, traumatic subluxation, or compressive myelopathy. Nerve conduction studies, including needle electromyography, showed decreased motor unit recruitment in the bilateral first dorsal interosseous and right deltoid, biceps, and triceps muscles confirming PTS. The patient was treated with 40 mg/day of oral prednisone and occupational therapy to maintain range of motion and activities of daily living. PTS is also known as neuralgic amyotrophy, brachial plexus neuritis, brachial plexopathy, and shoulder-girdle syndrome. It is characterized by asymmetrical, chronic, resistant upper extremity neuropathic pain and neurological defects such as paralysis and paresthesia. There are two different types of PTS: non-hereditary and inherited. The etiology and pathophysiology of PTS are not fully understood. Various aspects such as genetic, environmental, and immunological predisposition may play a role in developing the syndrome. Infections, vaccines, and injuries are typical causes of non-hereditary forms. After the COVID-19 epidemic and the commencement of a global immunization effort, similar instances happened. Presently there is no available test that unequivocally confirms or excludes PTS itself. Electrodiagnostic study and imaging modalities help to rule out other differential diagnoses. Also, there is no specific treatment available; however, it may resolve independently of treatment with supportive care.

Performance of specific morphologic features in distinguishing low-grade squamous intraepithelial lesions from high-grade squamous intraepithelial lesions in borderline cases: a College of American Pathologists Cytopathology Committee multiobserver study.

INTRODUCTION: Distinguishing between low-grade squamous intraepithelial lesions (LSIL) and high-grade squamous intraepithelial lesions (HSIL) can be difficult on certain Papanicolaou (Pap) tests, hindering interobserver concordance. We investigated the variables influencing the interpretation of LSIL versus HSIL in Pap test slides rejected from the College of American Pathologists PAP education program. MATERIALS AND METHODS: Eleven cytologists, who were unaware of the reference interpretation, examined 21 Pap slides (11 submitted as LSIL and 10 as HSIL) rejected from the PAP education program and recorded the number of LSIL cells, HSIL cells, keratinized dysplastic cells, LSIL clusters with mixed HSIL cells, atypical squamous metaplasia, atypical glandular cells, the presence of inflammation or infectious organisms, and the overall interpretation (LSIL or HSIL). We evaluated the significance of these 11 variables using a nonlinear mixed model analysis. RESULTS: LSIL had greater concordance (92 of 121 responses; 76.0% concordance) than HSIL (68 of 110 responses; 61.8% concordance; P < 0.001). The only predictors of misclassified cases were the number of atypical squamous metaplastic cells and the number of HSIL cells (P < 0.001). The more of these cells identified, the more likely the reviewers were to classify the slide as HSIL. The reproducibility of the diagnosis was fair (Gwet's agreement coefficient, 0.33). CONCLUSIONS: Interobserver reproducibility is a challenge for a subset of cases with features intermediate between LSIL and HSIL. Atypical squamous metaplasia and dysplastic nuclei with a nuclear/cytoplasmic ratio greater than one half of the cell volume (HSIL) present on a Pap test influenced the likelihood that a reviewer would interpret the case as HSIL rather than LSIL.

Medically unexplained symptoms: assessment and management.

Medically unexplained symptoms or persistent physical symptoms are common, real and are associated with significant distress, loss of functioning and high healthcare costs. History, examination and appropriate investigations are essential to make a diagnosis. Once the diagnosis has been made, exploring the impact of the symptoms helps us to tailor our advice to patients. This paper sets out a practical approach to taking a history, assessment and stepwise management principles.

Identifying and managing functional cardiac symptoms.

Recurring chest pain and other cardiac symptoms that cannot be adequately explained by organic pathology are common and can be associated with substantial disability, distress and high healthcare costs. Common mental disorders such as depression and anxiety frequently co-occur with these symptoms and, in some cases, account for their presentation, although they are not universally present. Due to the frequency of functional cardiac presentations and risks of iatrogenic harm, physicians should be familiar with strategies to identify, assess and communicate with patients about these symptoms. A systematic and multidisciplinary approach to diagnosis and management is often needed. Health beliefs, concerns and any associated behaviours should be elicited and addressed throughout. Psychiatric comorbidities should be concurrently identified and treated. For those with persistent symptoms, psychosocial outcomes can be poor, highlighting the need for further research and investment in diagnostic and therapeutic approaches and multidisciplinary service models.

BMC family practice integrated GP care for patients with persistent physical symptoms: feasibility cluster randomised trial.

BACKGROUND: Patients continue to suffer from medically unexplained symptoms otherwise referred to as persistent physical symptoms (PPS). General practitioners (GPs) play a key role in the management of PPS and require further training. Patients are often frustrated with the care they receive. This study aims to assess the acceptability of an 'integrated GP care' approach which consists of offering self-help materials to patients with PPS and offering their GPs training on how to utilise cognitive behavioural skills within their consultations, as well as assessing the feasibility of conducting a future trial in primary care to evaluate its benefit. METHODS: A feasibility cluster randomised controlled trial was conducted in primary care, South London, UK. GP practices (clusters) were randomly allocated to 'integrated GP care plus treatment as usual' or 'treatment as usual'. Patients with PPS were recruited from participating GP practices before randomisation. Feasibility parameters, process variables and potential outcome measures were collected at pre-randomisation and at 12- and 24-weeks post-randomisation at cluster and individual participant level. RESULTS: Two thousand nine hundred seventy-eight patients were identified from 18 GP practices. Out of the 424 patients who responded with interest in the study, 164 fully met the eligibility criteria. One hundred sixty-one patients provided baseline data before cluster randomisation and therefore were able to participate in the study. Most feasibility parameters indicated that the intervention was acceptable and a future trial feasible. 50 GPs from 8 GP practices (randomised to intervention) attended the offer of training and provided positive feedback. Scores in GP knowledge and confidence increased post-training. Follow-up rate of patients at 24 weeks was 87%. However estimated effect sizes on potential clinical outcomes were small. CONCLUSIONS: It was feasible to identify and recruit patients with PPS. Retention rates of participants up to 24 weeks were high. A wide range of health services were used. The intervention was relatively low cost and low risk. This complex intervention should be further developed to improve patients'/GPs' utilisation of audio/visual and training resources before proceeding to a full trial evaluation.

Mental health in South East London general hospitals: using electronic patient records to explore associations between psychiatric diagnoses and length of stay in a patient cohort receiving liaison psychiatry input.

BACKGROUND: Psychiatric illnesses are prevalent in general hospitals and associated with length of stay (LOS). Liaison psychiatry teams provide psychiatric care in acute hospitals and can improve mental health-related outcomes but, to achieve ambitious policy targets, services must understand local need. AIMS: Using electronic patient records, we investigate associations between psychiatric diagnoses and LOS in South East London hospitals. METHOD: Patient records were extracted using the South London and Maudsley NHS Foundation Trust Biomedical Research Centre Case Register Interactive Search system. There were 6378 admissions seen by liaison psychiatry aged <65 years between 2011 and 2016. Linear mixed-effects models investigated the impact of psychiatric diagnoses on LOS. Potential confounders included medical diagnoses, gender, age, ethnicity, social deprivation, hospital site and investment per admission. RESULTS: According to marginal means, longer LOS is associated with primary diagnoses of organic disorders (mean: 23 days, 95% CI 20.39-25.61), depressive disorders (mean: 11.03 days, 95% CI 9.74-25.61) and psychotic disorders (mean: 10.63 days, 95% CI 8.75-12.51). Shorter LOS is associated with personality disorders (mean: 6.28 days, 95% CI 4.12-8.45), bipolar affective disorders (mean 6.81 days, 95% CI 3.49-10.14) and substance-related problems (mean 7.53 days, 95% CI 6.01-9.05). CONCLUSIONS: Psychiatric diagnoses have differential associations with in-patient LOS. Liaison psychiatry teams aim to mitigate the impact of psychiatric illness on patient and hospital outcomes but understanding local need and the wider context of care provision is needed to maximise potential benefits. DECLARATION OF INTEREST: M.H. is a consultant liaison psychiatrist for King's College Hospital adult liaison psychiatry team. At the time of writing, H.T. was senior business manager at SLaM psychological medicine and integrated care clinical academic group. These may be considered financial and/or non-financial interests given the implications of findings for service funding.

Persistent physical symptoms reduction intervention: a system change and evaluation in secondary care (PRINCE secondary) - a CBT-based transdiagnostic approach: study protocol for a randomised controlled trial.

BACKGROUND: Persistent physical symptoms (PPS), also known as medically unexplained symptoms (MUS), affect approximately 50% of patients in secondary care and are often associated with disability, psychological distress and increased health care costs. Cognitive behavioural therapy (CBT) has demonstrated both short- and long-term efficacy with small to medium effect sizes for PPS, with larger treatment effects for specific PPS syndromes, including non-cardiac chest pain, irritable bowel syndrome (IBS) and chronic fatigue syndrome (CFS). Research indicates that PPS conditions share similar cognitive and behavioural responses to symptoms, such as avoidance and unhelpful beliefs. This suggests that a transdiagnostic approach may be beneficial for patients with PPS. METHODS: A randomised controlled trial (RCT) will be conducted to evaluate the efficacy and cost-effectiveness of a transdiagnostic CBT-based intervention for PPS. 322 participants with PPS will be recruited from secondary care clinics. Participants stratified by clinic and disability level will be randomised to CBT plus standard medical care (SMC) versus SMC alone. The intervention consists of 8 CBT sessions delivered by a qualified therapist over a period of 20 weeks. Outcomes will be assessed at 9, 20, 40- and 52-weeks post randomisation. Efficacy will be assessed by examining the difference between arms in the primary outcome Work and Social Adjustment Scale (WSAS) at 52 weeks after randomisation. Secondary outcomes will include mood, symptom severity and clinical global impression at 9, 20, 40 and 52 weeks. Cost-effectiveness will be evaluated by combining measures of health service use, informal care, loss of working hours and financial benefits at 52 weeks. DISCUSSION: This trial will provide a powered evaluation of the efficacy and cost-effectiveness of a transdiagnostic CBT approach versus SMC for patients with PPS. It will also provide valuable information about potential healthcare pathways for patients with PPS within the National Health Service (NHS). TRIAL REGISTRATION: ClinicalTrials.gov NCT02426788. Registered 27 April 2015. Overall trial status: Ongoing; Recruitment status: No longer recruiting.

Persistent physical symptoms reduction intervention: a system change and evaluation (PRINCE)-integrated GP care for persistent physical symptoms: protocol for a feasibility and cluster randomised waiting list, controlled trial.

INTRODUCTION: Persistent physical symptoms (PPS), also known as medically unexplained symptoms are associated with profound physical disability, psychological distress and high healthcare costs. England's annual National Health Service costs of attempting to diagnose and treat PPS amounts to approximately £3 billion. Current treatment relies on a positive diagnosis, life-style advice and drug therapy. However, many patients continue to suffer from ongoing symptoms and general practitioners (GPs) are challenged to find effective treatments. Training GPs in basic cognitive behavioural skills and providing self-help materials to patients could be useful, but availability in primary care settings is limited. METHODS AND ANALYSIS: A cluster randomised waiting list, controlled trial will be conducted to assess the feasibility of an integrated approach to care in general practice. Approximately 240 patients with PPS will be recruited from 8 to 12 GP practices in London. GP practices will be randomised to 'integrated GP care plus treatment as usual' or waiting list control. Integrated GP care plus treatment as usual will include GP training in cognitive behavioural skills, GP supervision and written and audio visual materials for both GPs and participants. The primary objectives will be assessment of trial and intervention feasibility. Secondary objectives will include estimating the intracluster correlation coefficient for potential outcome measures for cluster effects in a sample size calculation. Feasibility parameters and identification of suitable primary and secondary outcomes for future trial evaluations will be assessed prerandomisation and at 12 and 24 weeks' postrandomisation, using a mixed-methods approach. ETHICS AND DISSEMINATION: Ethical approval was granted by the Camberwell St Giles Ethics Committee. Results will be disseminated via peer-reviewed publications and conference presentations. This trial will inform researchers, clinicians, patients and healthcare providers about the feasibility and potential cost-effectiveness of an integrated approach to managing PPS in primary care. TRIAL REGISTRATION NUMBER: NCT02444520; Pre-results.

Post-Brachytherapy Transformation of Prostatic Adenocarcinoma to Squamous Cell Carcinoma: A Cadaver Anatomy Case Report.

Prostatic squamous cell carcinoma comprises less than 1% of reported prostate cancers. This form of cancer has a poor prognosis with a low survival time following diagnosis and no definitive form of treatment. A Caucasian male cadaver presented with primary pure squamous cell carcinoma of the prostate with metastasis to the liver and local invasion of the bladder, ureter, and rectum. Post-mortem examination showed evidence of brachytherapy radiation seeds in the prostate. Histological analysis and clinical intuition suggest that these seeds were used in an attempt to treat a previous low-grade adenocarcinoma of the prostate. The lack of patient history complicates determining a definitive cause of death, but the pathological presentation strongly suggests that the cause of death was a pure squamous cell carcinoma of the prostate following brachytherapy treatment for a previous prostatic adenocarcinoma. This case report further aids in establishing the relationship between the use of brachytherapy for prostatic adenocarcinoma and the subsequent development of prostatic squamous cell carcinoma.

Low-Grade Squamous Intraepithelial Lesion or High-Grade Squamous Intraepithelial Lesion? Concordance Between the Interpretation of Low-Grade Squamous Intraepithelial Lesion and High-Grade Squamous Intraepithelial Lesion in Papanicolaou Tests: Results From the College of American Pathologists PAP Education Program.

CONTEXT.­: Obtaining diagnostic concordance for squamous intraepithelial lesions in cytology can be challenging. OBJECTIVE.­: To determine diagnostic concordance for biopsy-proven low-grade squamous intraepithelial lesion (LSIL) and high-grade squamous intraepithelial lesion (HSIL) Papanicolaou test slides in the College of American Pathologists PAP Education program. DESIGN.­: We analyzed 121 059 responses from 4251 LSIL and HSIL slides for the interval 2004 to 2013 using a nonlinear mixed-model fit for reference diagnosis, preparation type, and participant type. We evaluated interactions between the reference diagnosis and the other 2 factors in addition to a repeated-measures component to adjust for slide-specific performance. RESULTS.­: There was a statistically significant difference between misclassification of LSIL (2.4%; 1384 of 57 664) and HSIL (4.4%; 2762 of 63 395). There was no performance difference between pathologists and cytotechnologists for LSIL, but cytotechnologists had a significantly higher HSIL misclassification rate than pathologists (5.5%; 1437 of 27 534 versus 4.0%; 1032 of 25 630; P = .01), and both were more likely to misrepresent HSIL as LSIL ( P < .001) than the reverse. ThinPrep LSIL slides were more likely to be misclassified as HSIL (2.4%; 920 of 38 582) than SurePath LSIL slides (1.5%; 198 of 13 196), but conventional slides were the most likely to be misclassified in both categories (4.5%; 266 of 5886 for LSIL, and 6.5%; 573 of 8825 for HSIL). CONCLUSIONS.­: More participants undercalled HSIL as LSIL (false-negative) than overcalled LSIL as HSIL (false-positive) in the PAP Education program, with conventional slides more likely to be misclassified than ThinPrep or SurePath slides. Pathologists and cytotechnologists classify LSIL equally well, but cytotechnologists are significantly more likely to undercall HSIL as LSIL than are pathologists.

False-Negative Interpretation of Adenocarcinoma In Situ in the College of American Pathologists Gynecologic PAP Education Program.

CONTEXT: - Adenocarcinoma in situ (AIS) is difficult to correctly interpret on Papanicolaou (Pap) cytology slides and false-negative interpretations of AIS can cause significant problems in daily practice. OBJECTIVE: - To investigate the false-negative interpretation rate of AIS and the factors related to false-negative interpretation through responses in an educational environment. DESIGN: - We retrospectively evaluated 11 337 responses in the PAP Education Program (PAP-Edu) from 173 AIS slides from 2011 to 2015. The false-negative interpretation rate, most common false-negative interpretations, and related other factors were evaluated. RESULTS: - The overall false-negative rate was 6.9% (784 of 11 337). Respondents correctly interpreted AIS 50.0% (5667 of 11 337) of the time; high-grade intraepithelial lesion (HSIL) and malignancies (adenocarcinoma, squamous cell carcinoma, and other carcinomas) accounted for 42.7% (4842 of 11 337) and low-grade intraepithelial lesion accounted for 0.4% (44 of 11 337) of responses. Overall, 92.7% (10 509 of 11 337) of responses were HSIL and above. Among 784 false-negative responses, negative for intraepithelial lesion or malignancy was the most common (61.5% [482 of 784]), followed by reparative changes (24.1% [189 of 784]) and atrophic vaginitis (7.7% [60 of 784]). Overall, pathologists' responses showed a significantly higher false-negative rate than cytotechnologists' responses (8.3%, 403 of 4835 versus 5.7%, 275 of 4816; P < .001). The false-negative response rates were not statistically different among preparation types. CONCLUSIONS: - The low correct interpretation rate and higher false-negative rate for AIS demonstrate the difficulty in interpreting AIS on Pap cytology, which may cause clinical consequences. The higher false-negative rate with pathologists than with cytotechnologists suggests cytotechnologists' higher screening sensitivity for AIS or cautious interpretation to avoid false-positive results by pathologists.

Update on the College of American Pathologists Experience With High-Risk Human Papillomavirus Proficiency Testing for Cytology.

CONTEXT: - Since 2008, the College of American Pathologists has provided the human papillomavirus for cytology laboratories (CHPV) proficiency testing program to help laboratories meet the requirements of the Clinical Laboratory Improvement Amendments of 1988. OBJECTIVES: - To provide an update on trends in proficiency testing performance in the College of American Pathologists CHPV program during the 4-year period from 2011 through 2014 and to compare those trends with the preceding first 3 years of the program. DESIGN: - Responses of laboratories participating in the CHPV program from 2011 through 2014 were analyzed using a nonlinear mixed model to compare different combinations of testing medium and platform. RESULTS: - In total, 818 laboratories participated in the CHPV program at least once during the 4 years, with participation increasing during the study period. Concordance of participant responses with the target result was more than 98% (38 280 of 38 892). Overall performance with all 3 testing media-ThinPrep (Hologic, Bedford, Massachusetts), SurePath (Becton, Dickinson and Company, Franklin Lakes, New Jersey), or Digene (Qiagen, Valencia, California)-was equivalent (P = .51), and all 4 US Food and Drug Administration (FDA)-approved platforms-Hybrid Capture 2 (Qiagen), Cervista (Hologic), Aptima (Hologic), and cobas (Roche Molecular Systems, Pleasanton, California)-outperformed laboratory-developed tests, unspecified commercial kits, and other (noncommercial) methods in ThinPrep medium (P < .001). However, certain off-label combinations of platform and medium, most notably Cervista with SurePath, demonstrated suboptimal performance (P < .001). CONCLUSIONS: - Laboratories demonstrated proficiency in using various combinations of testing media and platforms offered in the CHPV program, with statistically significant performance differences in certain combinations. These observations may be relevant in the current discussions about FDA oversight of laboratory-developed tests.

Postmortem Aortic Dissection: An Artifact of the Embalming Process.

Aortic dissection (AD) is a serious condition that affects 3/100,000 individuals a year. Recently, a case report was published describing an embalmed patient with an aortic dissection. The purpose of this study was to examine the frequency of AD among 80 embalmed cadavers and confirm the AD with histopathologic evaluation. In seven cases of grossly identified AD, six were determined to be due to the embalming procedure and only one case of true antemortem AD was confirmed. These results suggest that aortic morphology can be altered by administration of the embalming fluid and that alterations can mimic AD, not only on gross inspection but also on postmortem imaging. Awareness of this embalming artifact may prevent misdiagnosis of an aortic dissection in an embalmed patient, a point particularly useful for autopsy pathology that may include postmortem examination of an embalmed patient.

Human papillomavirus testing and reporting rates in 2012: results of a College of American Pathologists national survey.

CONTEXT: College of American Pathologists (CAP) surveys are used to establish national benchmarks for laboratory parameters. OBJECTIVE: To evaluate changes in laboratory human papillomavirus (HPV) testing patterns in laboratories incorporating HPV testing with Papanicolaou tests in 2012. DESIGN: Data were analyzed from the CAP HPV Supplemental Questionnaire distributed to 1771 laboratories participating in either CAP HPV or CAP Papanicolaou proficiency testing in 2013. RESULTS: A total of 1022 laboratories (58%) responded. There were more high-risk (HR) HPV tests performed per institution as compared to previous surveys. There were more HPV tests performed within an institution as compared to previous surveys. Hybrid Capture 2 (HC2) remains the most common method (42.4%, 239 of 564); Cervista and cobas methods are used in 37.2% (210 of 564) and 14.9% (84 of 564) of laboratories, respectively. Human papillomavirus testing is offered as a reflex test after a Papanicolaou test result of atypical squamous cells of undetermined significance (ASC-US) in 89.6% of laboratories (476 of 531); as a cotest for women aged 30 years and older in 60.3% (404 of 531); as reflex testing after atypical squamous cells, cannot exclude high-grade squamous intraepithelial lesion (ASC-H) in 42.7% (320 of 531); and as reflex testing after atypical glandular cells (AGC) in 27.3% (145 of 531). The HPV-positive rates for ASC-US and ASC-H were similar in 2012 and 2006. Cervista (49.2%, 88 of 179) and Roche cobas (27.4%, 49 of 179) are the most common methods used for genotyping. Most laboratories use the CAP Human Papillomavirus for Cytology Program for proficiency testing. CONCLUSIONS: There was an increase in annual volume of HR-HPV testing with a shift toward in-house HR-HPV testing. Genotyping volumes also increased. HC2 and Cervista are most commonly used, with an increasing volume of Roche cobas testing. The most common indication for HPV testing among all laboratories was ASC-US reflex testing, but an increase in HPV cotesting was observed. The data provide an update into persisting and newer trends in HPV testing practices.

Diagnosis of sebaceous lymphadenoma by fine needle aspiration in a patient with Cowden syndrome: Case report and review of the literature.

Sebaceous lymphadenoma (SLA) is a rare benign tumor of the salivary gland that commonly arises in the parotid gland in adults. It is rarely diagnosed correctly preoperatively. In addition, to the best of our knowledge, SLA has not been described yet in the literature in association with Cowden's syndrome (CS). We present an extremely rare case of parotid SLA that was diagnosed preoperatively by fine needle aspiration in a patient with CS.

The Bethesda System thyroid diagnostic categories in the African-American population in conjunction with surgical pathology follow-up.

BACKGROUND: It has been reported that African-Americans (AA) have a higher prevalence of overall malignancy compared to Caucasians, in the United States, yet the incidence of thyroid malignancy is half. The aim of this study is to assess the rate of malignant versus benign thyroid disease in AA from an urban-based hospital with an academic setting. Our study analyzed the AA population with respect to fine needle aspiration (FNA) of thyroid lesions, in correlation with final surgical pathology. This is the first study of its kind to our knowledge. DESIGN: We retrospectively reviewed thyroid FNA cytology between January 2005 and February 2011. Consecutive FNA specimens with corresponding follow-up surgical pathology were included. The patients were categorized as African- American (AA) and Non-African-American (NAA), which included Caucasians (C), Hispanics (H), and Others (O). The FNA results were classified using the latest edition of The Bethesda System for Reporting Thyroid Cytopathology (TBS-Thy) and the follow-up surgical pathology was used for the final categorization. RESULTS: We studied 258 cases: 144 AA (56%) and 114 NAA [43 C (17%), 3 H (1%), and 68 O (28%)]. The average age for AA was 51 years (range 20 - 88) and for NAA was 53 years (range 25 - 86). There were more females than males in the AA versus the NAA group (85 vs. 75%). The incidence of thyroid lesions in the FNA specimens was similar between these two populations. The distribution of benign versus malignant diagnosis on follow-up surgical pathology was examined across TBS-Thy class. CONCLUSION: Our data suggest that distribution of benign versus malignant lesions in the thyroid FNA of AA versus NAA, with follow-up surgical pathology, is comparable for TBS-Thy classes, non-diagnostic (I), benign (II), suspicious for malignancy (V), and malignant (VI) in AA versus NAA.
