Bringing Reproductive Health Guidelines Into Fellowship Training: A National Survey of Adult and Pediatric Rheumatology Fellows and Program Directors.

OBJECTIVE: This study seeks to assess rheumatology fellows' (RFs') and program directors' (PDs') interests in different educational tools and methods and to facilitate curriculum development for reproductive health related to rheumatic disease. METHODS: Constructs were conceptualized in four dimensions: 1) RF and PD confidence in their current curriculum relating to the American College of Rheumatology (ACR) Reproductive Health Guidelines (RHGs), 2) personal interest in this topic, 3) opinions of the importance of this topic, and 4) interest in a range of learning materials and educational experiences. The final survey was distributed to 753 RFs and 179 PDs in the United States using the ACR Committee on Training and Workforce email list. RESULTS: Response rates were 13% (n = 98) for RFs and 25% (n = 44) for PDs. Both groups indicated more interest in the topic than confidence in their curriculum and rated summary sheets, question banks, didactics, and online modules higher than nine other educational tools or methods. Despite interest in the topic, 38% of RF respondents and 24% of PD respondents were unaware of the recently published ACR RHGs. CONCLUSION: RFs and PDs consider reproductive health very important and report high personal interest in this topic. In contrast, both groups indicated lower confidence in current curricula, and substantial proportions of both groups were unaware of recently published guidelines. RFs' and PDs' interests in specific educational modalities are aligned. Curriculum development efforts should prioritize summary sheets, question banks, didactics, and online modules. Efforts are needed to address the educational needs of practicing rheumatologists and other professionals caring for patients with rheumatic disease.

AI-Based Automated Lipomatous Tumor Segmentation in MR Images: Ensemble Solution to Heterogeneous Data.

Deep learning (DL) has been proposed to automate image segmentation and provide accuracy, consistency, and efficiency. Accurate segmentation of lipomatous tumors (LTs) is critical for correct tumor radiomics analysis and localization. The major challenge of this task is data heterogeneity, including tumor morphological characteristics and multicenter scanning protocols. To mitigate the issue, we aimed to develop a DL-based Super Learner (SL) ensemble framework with different data correction and normalization methods. Pathologically proven LTs on pre-operative T1-weighted/proton-density MR images of 185 patients were manually segmented. The LTs were categorized by tumor locations as distal upper limb (DUL), distal lower limb (DLL), proximal upper limb (PUL), proximal lower limb (PLL), or Trunk (T) and grouped by 80%/9%/11% for training, validation and testing. Six configurations of correction/normalization were applied to data for fivefold-cross-validation trainings, resulting in 30 base learners (BLs). A SL was obtained from the BLs by optimizing SL weights. The performance was evaluated by dice-similarity-coefficient (DSC), sensitivity, specificity, and Hausdorff distance (HD95). For predictions of the BLs, the average DSC, sensitivity, and specificity from the testing data were 0.72 [Formula: see text] 0.16, 0.73 [Formula: see text] 0.168, and 0.99 [Formula: see text] 0.012, respectively, while for SL predictions were 0.80 [Formula: see text] 0.184, 0.78 [Formula: see text] 0.193, and 1.00 [Formula: see text] 0.010. The average HD95 of the BLs were 11.5 (DUL), 23.2 (DLL), 25.9 (PUL), 32.1 (PLL), and 47.9 (T) mm, whereas of SL were 1.7, 8.4, 15.9, 2.2, and 36.6 mm, respectively. The proposed method could improve the segmentation accuracy and mitigate the performance instability and data heterogeneity aiding the differential diagnosis of LTs in real clinical situations.

Qualitative evaluation of MRI features of lipoma and atypical lipomatous tumor: results from a multicenter study.

OBJECTIVES: The objectives of the study are (1) to distinguish lipoma (L) from atypical lipomatous tumor (ALT) using MRI qualitative features, (2) to assess the value of contrast enhancement, and (3) to evaluate the reproducibility and confidence level of radiological readings. MATERIALS AND METHODS: Patients with pathologically proven L or ALT, who underwent MRI within 3 months from surgical excision were included in this retrospective multicenter international study. Two radiologists independently reviewed MRI centrally. Impressions were recorded as L or ALT. A third radiologist was consulted for discordant readings. The two radiologists re-read all non-contrast sequences; impression was recorded; then post-contrast images were reviewed and any changes were recorded. RESULTS: A total of 246 patients (135 females; median age, 59 years) were included. ALT was histopathologically confirmed in 70/246 patients. In multivariable analysis, in addition to the lesion size, deep location, proximal lower limb lesions, demonstrating incomplete fat suppression, or increased architectural complexity were the independent predictive features of ALT; but not the contrast enhancement. Post-contrast MRI changed the impression in a total of 5 studies (3 for R1 and 4 for R2; 2 studies are common); all of them were incorrectly changed from Ls to ALTs. Overall, inter-reader kappa agreement was 0.42 (95% CI 0.39-0.56). Discordance between the two readers was statistically significant for both pathologically proven L (p < 0.001) and ALT (p = 0.003). CONCLUSION: Most qualitative MR imaging features can help distinguish ALTs from BLs. However, contrast enhancement may be limited and occasionally misleading. Substantial discordance on MRI readings exists between radiologists with a relatively high false positive and negative rates.

Statin-Associated Necrotizing Autoimmune Myositis Complicated by an Uncommon Adverse Effect to Treatment.

Statin-associated necrotizing autoimmune myositis (NAM) is an autoimmune condition characterized by severe acute-onset proximal muscle weakness, a very high creatinine kinase (CK) level, and prominent myofiber necrosis and minimal lymphocytic infiltration on muscle biopsy. Unlike self-limited statin myopathy, this condition usually requires aggressive immunomodulation therapy to assist recovery and prevent future disability. In this case report, we present a patient who developed progressive muscle weakness after taking atorvastatin for one year. At initial presentation, her CK level was 28,000 U/L. She was diagnosed with statin-associated NAM and started on high-dose intravenous solumedrol, mycophenolate, and intravenous immunoglobulin (IVIG) therapy. However, she subsequently developed acute bilateral vision loss and right side hemineglect; she was diagnosed with posterior reversible encephalopathy syndrome (PRES), thought to be a possible delayed adverse reaction to IVIG. IVIG was discontinued, and the patient was treated with supportive therapy. At six-month follow-up, she had significant improvement in muscle strength and vision.

An Interesting Case of Neurobrucellosis Mimicking Neuropsychiatric Lupus.

This case describes a patient presenting with acute onset papilledema, subacute strokes resulting in upper extremity weakness and numbness, arthritis, maculopapular rash, depressed C4 and CH50, and a high titer anti-double-stranded DNA antibody. The patient was given the diagnosis of probable systemic lupus erythematosus, which was supported by the Systemic Lupus International Collaborating Clinics (SLICC) criteria. He was aggressively treated for neuropsychiatric lupus (NPSLE) with pulse dose steroids and a dose of intravenous cyclophosphamide. Blood cultures drawn on admission later grew out 2/4 bottles of Gram-variable bacteria, speciated as Brucella melitensis by PCR. Serum Brucella serologies were also positive. On further evaluation, the patient noted a history of eating unpasteurized cheese in Mexico. Given these additional findings, the patient's presentation was most consistent with a diagnosis of neurobrucellosis. Steroids were tapered off, no further doses of cyclophosphamide were given, and a prolonged course of intravenous and oral antibiotic therapy was administered, resulting in complete resolution of the patient's presenting symptoms.

Retroperitoneal Angiomatoid Fibrous Histiocytoma Presenting as a Recurrent Spontaneous Retroperitoneal Hemorrhage in a 9-Year-Old Boy.

Angiomatoid fibrous histiocytoma (AFH) is a rare soft tissue tumor that typically presents in children and young adults. Occurrence outside of the extremities and the head and neck region is exceedingly rare. We report the case of a 9-year-old boy who presented with recurrent retroperitoneal hemorrhage initially thought to be a manifestation of an underlying bleeding disorder. After comprehensive diagnostic work-up, including multiple negative biopsies, the patient underwent surgical resection of an extensively hemorrhagic intramuscular mass and to date remains well. Pathologic examination confirmed AFH with EWSR1 gene rearrangement. This first documented report of an AFH in a retroperitoneal location in a child highlights the diagnostic difficulties and clinical challenges of AFH arising in an atypical location.

A Rare Case of Digital Ischemia and Gangrene in ANCA-Associated Vasculitis with Review of the Literature.

This paper describes one patient with Antineutrophil Cytoplasmic Antibody- (ANCA-) associated vasculitis who initially presented with multiple ischemic fingers and toes. On further evaluation, the patient was also found to have pulmonary-renal involvement and episcleritis. The diagnosis was supported with a positive cANCA (anti-proteinase 3) and a bronchoscopy consistent with diffuse alveolar hemorrhage. Although the patient refused a tissue biopsy, clinical presentation including nasal ulceration, sinus congestion, and epistaxis and anti-proteinase 3 antibody were more consistent with Granulomatosis with Polyangiitis (GPA) rather than Microscopic Polyangiitis (MPA) or Eosinophilic Granulomatosis with Polyangiitis (EGPA) based on the recently presented ACR/EULAR Provisional 2017 Classification Criteria for GPA (Luqmani et al., 2016). The patient responded well to therapy including high dose steroids and cyclophosphamide, with improvement of all organs involved and had no further digital ischemia or gangrene on follow-up. We include a review of the English literature summarizing presentation, management, and outcome of 16 similar cases.

Fever, Myositis, and Paralysis: Is This Inflammatory Myopathy or Neuroinvasive Disease?

West Nile virus (WNV) is a mosquito-borne RNA Flavivirus which emerged in North America in 1999. Most patients present with a febrile illness but a few develop WNV neuroinvasive disease. Myopathy is an uncommon manifestation. We describe a case of a 42-year-old male from Los Angeles who presented with 8 days of fever and muscle pain. Initial physical exam was normal except for 4/5 muscle strength testing in his extremity proximal muscles. Laboratory revealed a creatine kinase of 45,000 and a urinalysis with large blood but no red blood cells, suggesting rhabdomyolysis. The patient's condition declined despite aggressive supportive care and hydration, and on hospital day #6 he developed severe altered mental status and progressed to complete right arm paralysis and 2/5 muscle strength in bilateral legs. EMG/NCS showed sensorimotor axonal polyneuropathy and the cerebrospinal fluid was positive for IgM and IgG WNV antibodies. The patient was diagnosed with WNV neuroinvasive disease, poliomyelitis (and encephalitis) type with myopathy/muscle involvement. He was treated supportively and his muscle and neurologic disease gradually improved. At 12-month follow-up his muscle enzymes had normalized and his weakness had improved to 5/5 strength in bilateral legs and 3/5 strength in the right arm.

Inflammatory Biomarkers, Comorbidity, and Neurocognition in Women With Newly Diagnosed Breast Cancer.

BACKGROUND: Neurocognitive dysfunction is reported in women with breast cancer even prior to receipt of adjuvant therapy; however, there is little understanding of underlying mechanisms. We tested the hypothesis that pretreatment neurocognitive dysfunction in newly diagnosed patients is related to immunological activation, as indexed by pro-inflammatory cytokines. METHODS: One hundred seventy-four postmenopausal patients with newly diagnosed breast cancer underwent a comprehensive neuropsychological evaluation (assessment of cognitive function, mood, and fatigue) and measurement of key cytokine levels prior to surgery. Age-matched control participants without cancer were evaluated concurrently. Multivariable regression analyses examined the contribution of circulating Interleukin-6 (IL-6), interleukin-1 receptor antagonist (IL-1ra), and soluble TNF receptor type two (sTNF-RII) in predicting neurocognitive performance in patients after controlling for key factors thought to impact functioning. All tests of statistical significance were two-sided. RESULTS: Memory performance was statistically significantly reduced, in patients compared with controls (P = .02). Of the three cytokines measured, only IL-1ra was statistically significantly elevated in cancer patients when compared with control participants (mean ± SD, 375 ± 239 pg/mL vs 291 ± 169 pg/mL, P = .007). After controlling for age, education, race, mood, fatigue, body mass index, and comorbidity, cytokines independently explained 6.0% of the total variance in memory performance (P = .01) in cancer patients but not control participants, with higher sTNF-RII associated with worse functioning. Exploratory analyses found that comorbidity statistically significantly explained variance in processing speed and executive functioning (P = .03 and P = .03, respectively). CONCLUSION: An association of TNF with memory, previously reported in patients after exposure to chemotherapy, was found prior to initiation of any treatment, including surgery. This association requires further investigation as sTNF-RII was not higher in cancer patients relative to control participants.

Acute hemorrhagic myositis in inflammatory myopathy and review of the literature.

We describe two patients with dermatomyositis that presented with interstitial lung disease, positive V and Shawl sign who developed acute spontaneous abdominal/retroperitoneal bleed. Both patients expired despite aggressive treatment and resuscitation. Hemorrhagic myositis in these two patients with inflammatory myopathy is a very rare complication. The association of anti-Ro52 with this potentially very serious complication remains unclear. This potential relationship should be further evaluated in future studies.

Memory for performed and observed activities following traumatic brain injury.

Traumatic brain injury (TBI) is associated with deficits in memory for the content of completed activities. However, TBI groups have shown variable memory for the temporal order of activities. We sought to clarify the conditions under which temporal order memory for activities is intact following TBI. Additionally, we evaluated activity source memory and the relationship between activity memory and functional outcome in TBI participants. Thus, we completed a study of activity memory with 18 severe TBI survivors and 18 healthy age- and education-matched comparison participants. Both groups performed eight activities and observed eight activities that were fashioned after routine daily tasks. Incidental encoding conditions for activities were utilized. The activities were drawn from two counterbalanced lists, and both performance and observation were randomly determined and interspersed. After all of the activities were completed, content memory (recall and recognition), source memory (conditional source identification), and temporal order memory (correlation between order reconstruction and actual order) for the activities were assessed. Functional ability was assessed via the Community Integration Questionnaire (CIQ). In terms of content memory, TBI participants recalled and recognized fewer activities than comparison participants. Recognition of performed and observed activities was strongly associated with social integration on the CIQ. There were no between- or within-group differences in temporal order or source memory, although source memory performances were near ceiling. The findings were interpreted as suggesting that temporal order memory following TBI is intact under conditions of both purposeful activity completion and incidental encoding, and that activity memory is related to functional outcomes following TBI.

Parenting stress and neurocognitive late effects in childhood cancer survivors.

BACKGROUND: Surveillance of neurocognitive late effects has typically focused on the pediatric survivor alone and rarely has focused on the potential family burden. We investigated the impact of child neurocognitive effects on parenting stress and hypothesized that parents of childhood cancer survivors with greater executive difficulties experience higher stress relative to parents of children with less adverse impact. METHODS: Parents of 44 children who survived cancer involving central nervous system-directed treatments and who had documented neurocognitive deficits completed standardized questionnaires assessing their perceived level of stress and perception of their child's executive functioning abilities in daily life. Data from performance-based cognitive tests were obtained on the children. Multiple regression models examined socio-demographic, clinical, and child's executive functioning as predictors of parent stress. Differences in parenting stress based on child's level of executive functioning were evaluated. RESULTS: Parent stress was significantly associated with both performance-based and parent report measures of child executive functioning. Child executive functioning significantly predicted parent stress even after controlling for socio-demographic and clinical factors, and the final model accounted for 42% of the variance in parent stress levels. Significant differences in parent stress were found when comparing higher versus lower levels of child executive functioning. The nature of the executive difficulties, however, appears important, as we found increased parenting stress among children with behavioral regulation problems rather than metacognitive difficulties. CONCLUSIONS: The associations between parenting stress and neurocognitive problems found in this study suggest the need for further research, along with professional monitoring and appropriate intervention.

Neonatal acute appendicitis: a proposed algorithm for timely diagnosis.

BACKGROUND: Neonatal appendicitis (NA) is a rare disease with a high mortality. The diagnosis has never been reported preoperatively and is notoriously difficult to make. METHODS: Charts since 1995 were retrospectively reviewed for discharge or death diagnoses of appendicitis in neonates younger than 28 days. We report 3 cases of NA seen at our institution during this period. RESULTS: All 3 infants were previously well, born at term, and presented with signs consistent with abdominal sepsis. The first 2 diagnoses were not made until autopsy. The third case survived after having an urgent computed tomographic scan, exploratory laparotomy, and appendectomy. DISCUSSION: The literature summarizing common presenting features of NA is reviewed. We present an algorithm to guide the workup of these neonates to facilitate earlier diagnosis and potentially improve outcomes.

Impact of cecostomy and antegrade colonic enemas on management of fecal incontinence and constipation: ten years of experience in pediatric population.

BACKGROUND: In childhood and adolescence, fecal soiling represents a psychologically devastating problem. Physical and emotional distress associated with daily rectal enemas is minimized by the introduction of a cecostomy tube for colonic cleansing with antegrade colonic enemas (ACEs). PATIENTS AND METHODS: Over a period of 10 years (1997-2007), we performed "button" cecostomies in 69 pediatric patients with fecal soiling secondary to a variety of disorders; laparoscopic procedures were performed in 40 and open procedures in 29. Mean postoperative follow-up was 4.03 SD +/- 1.76 years. Cleansing protocols differed between patients. RESULTS: We adopted a standardized questionnaire concerning management of incontinence/intractable constipation before and after button cecostomy insertion to assess the long-term impact of ACE on symptom severity and quality of life. Complications included tube dislodgement (n = 9), development of granulation tissue (n = 11), decubitus ulcer (n = 5), and infection (n = 3). Patient/parents satisfaction (appraisal scale 1-3) and improvement of quality of life achieved statistical significance for both (P < .001). CONCLUSIONS: Since button cecostomy and ACE were introduced in our institution as a management option, the treatment of fecal incontinence and intractable constipation significantly improved in terms of efficacy and patient compliance and also resulted in greater patient and parent satisfaction.

The complexity of care for patients with rheumatoid arthritis: metrics for better understanding chronic disease care.

BACKGROUND: Patients with rheumatoid arthritis (RA) provide an important opportunity for understanding care of patients with a serious chronic condition. OBJECTIVES: We sought to characterize the complexity of care for patients with RA, including metrics describing the patient, the disease, and use of the health care system across time and place. METHODS: We undertook a prospective cohort study of 568 community-dwelling patients with RA by using observational data from clinically detailed telephone interviews at baseline and 2 years later in addition to medical record abstraction. Health status, comorbidity, use of disease-modifying antirheumatic drugs, visits, providers, provider types, encounter settings, and the discontinuity between patients and providers were studied. RESULTS: Within a 12-month window, 568 patients had 8686 outpatient encounters with the health care system with a mean of 3.41 unique providers per patient associated with a mean of 5 primary care and 6 rheumatologist visits. Half did not see a primary care physician, and 20% did not see a rheumatologist during 6-month periods despite their use of potentially toxic drugs, a mean of 4 comorbidities and progressive RA. Over the course of 24 months, 29% of patients changed their primary care provider, and 15% changed their rheumatologist. Patients were moderately impaired with mean SF-12 physical component score 37 (SD, 9). CONCLUSION: Patients with RA have frequent encounters with multiple providers and also frequent discontinuity of care. Recognizing the complexity of the care of patients with a chronic disease across multiple dimensions provides an opportunity to better understand challenges and opportunities in delivering high quality care.

Lymphomatoid granulomatosis: a rare mimicker of vasculitis.

Lymphomatoid granulomatosis (LG) is a rare Epstein-Barr virus-associated lymphoproliferative disorder, with a propensity for blood vessel destruction. Although it most commonly affects the lung, it can affect multiple extrapulmonary sites (i.e., skin, nervous system, gastrointestinal tract, liver, spleen, kidney, and heart). Since LG often mimics systemic vasculitis, it presents a diagnostic clinical challenge. We describe a case of LG with no pulmonary involvement, which was thought to be systemic vasculitis on the basis of multiorgan involvement and biopsy findings.

Selective IgA immune unresponsiveness to Proteus mirabilis fumarate reductase A-chain in rheumatoid arthritis.

OBJECTIVE: To determine if selective immune unresponsiveness to microbial antigens is associated with predisposition to rheumatoid arthritis (RA). METHODS: Proteins from Proteus mirabilis lysate were isolated by SDS-PAGE and examined by Western blotting for antibody responses in sera from patients with RA compared to healthy subjects and patients with psoriatic arthritis (PsA). RESULTS: Although RA patients had marked IgA immune responses to many P. mirabilis proteins compared to healthy subjects, selective unresponsiveness was found in RA to a 66 kDa protein identified as fumarate reductase A-chain (FRD-A) by mass spectroscopy. This was confirmed in Western blots with recombinant FRD-A from P. mirabilis. IgA unresponsiveness to FRD-A was found in 21/59 (35.6%) RA patients compared to 7/63 (11.1%) healthy individuals (p < 0.01) and 6/52 (11.5%) patients with PsA (p < 0.01). IgA unresponsiveness to FRD-A was present in 20/46 (43.5%) RA patients with IgA rheumatoid factors (RF) compared to 1/13 (7.7%) without RF (p < 0.025). CONCLUSION: Our results identify a selective hole in the IgA immune repertoire for P. mirabilis FRD-A in a subset of IgA RF-positive patients with RA.

Development and evaluation of a patient self-report case-finding method for rheumatoid arthritis.

OBJECTIVE: To describe the development and evaluation of a patient self-report case-finding method for rheumatoid arthritis (RA) not dependent on direct contact with the treating physicians. METHODS: The American College of Rheumatology criteria for RA diagnosis were adapted for patient self-report using a questionnaire, and alternative scoring algorithms were evaluated to balance case-finding sensitivity and specificity. Positive rheumatoid factor tests were used to identify 1053 individuals in 2 large healthcare organizations; 440 agreed to receive study materials. Case-finding results were validated by medical record review (MRR) for a random sample of 90 patients. Three scoring algorithms were compared with MRR for likelihood of RA diagnosis. Cases not classifiable by algorithm were flagged and reviewed by 2 expert physicians for likelihood of RA diagnosis. RESULTS: Pilot testing demonstrated that patients comprehended the questionnaire and were willing to answer the questions. Completed questionnaires were returned by 265 (60%) of the 440 patients contacted. Following expert physician review of 16 flagged cases in the 90-patient MRR subsample, the most accurate scoring algorithm demonstrated 80% sensitivity, 67% specificity, 74% accuracy, and 77% positive predictive value for detecting early RA. CONCLUSION: The case-finding method represents a promising tool for identifying RA patients, with potential application in research and quality-assurance activities. RELEVANCE: This case-finding method should be useful in research and quality-assurance efforts requiring identification of RA patients treated by all types of providers in healthcare organizations in which centralized laboratory data are available.

Spanish Arthritis Empowerment Program: a dissemination and effectiveness study.

OBJECTIVE: To evaluate the effectiveness of the Spanish Arthritis Empowerment Program as presented by the Arthritis Foundation, Southern California Chapter, in Orange County, California. METHODS: Participants with arthritis (n = 141) enrolled in the program between October 1999 and May 2001. All materials were in Spanish. Written pretest, 6-week posttest, and 6-month followup tests measured pain rating, self-report joint counts, function (modified Health Assessment Questionnaire [mHAQ]), self efficacy, self-care behavior, and arthritis knowledge. RESULTS: Mean age was 51 years, 92% were female, 84% were born in Mexico, 55% had sixth grade education or less, and 60% had no medical insurance. Of the 141 participants, 118 completed 6-month followup testing. Repeated-measures analysis of variance showed significant improvement from pretest to 6-month followup in pain (6.0 versus 3.4); self efficacy (5.5 versus 8.4), self-care behavior (1.7 versus 4.9), arthritis knowledge (1.6 versus 4.5), and general health (2.1 versus 2.5), all at P < 0.001. Small improvement was reported in mHAQ (0.56 versus 0.50; P = 0.024). CONCLUSION: The Spanish Arthritis Empowerment Program was successfully disseminated. Significant improvements in self efficacy and in arthritis symptoms were maintained at the 6-month followup.
