Ultrasound, magnetic resonance imaging and radiography of the finger joints in psoriatic arthritis patients.

OBJECTIVES: To report the discrepancies and agreements between US, MRI and radiography of the hand in PsA, and to compare the sensitivity and specificity of US and radiography to MRI as the gold standard imaging study in PsA. METHODS: All of the 100 prospectively recruited consecutive PsA patients underwent clinical assessment and concomitant radiographic, US and MRI studies of the MCP, PIP and DIP joints of one hand. Synovitis, flexor tenosynovitis, extensor paratenonitis, erosions and bone proliferations were identified and scored. All readers were blinded to clinical data, and agreement was calculated based on prevalence-adjusted bias-adjusted kappa (PABAK). RESULTS: The prevalence of synovitis, flexor tenosynovitis, extensor paratenonitis and erosions was similar for US and MRI, while that of bone proliferation was significantly increased in US and radiography compared with MRI (P < 0.001). The absolute agreement between US and MRI was good-to-very good for synovitis (85-96%, PABAK = 0.70-0.92), flexor tenosynovitis (93-98%, PABAK = 0.87-0.96) and extensor paratenonitis (95-98%, PABAK = 0.90-0.97). Agreement between US, MRI and radiography was 96-98% (PABAK = 0.92-0.97) for erosions and 71-93% (PABAK = 0.47-0.87) for bone proliferations. Sensitivity of US with MRI as gold standard was higher for synovitis (0.5-0.86) and extensor paratenonitis (0.63-0.85) than for flexor tenosynovitis (0.1-0.75), while the specificity was high for each pathology (0.89-0.98). CONCLUSION: There is very good agreement between US and MRI for the detection of inflammatory changes in finger joints in PsA. US, radiography and MRI have a good-to-very good agreement for destructive changes.

Role of ultrasound for assessment of psoriatic arthritis patients with fibromyalgia.

OBJECTIVE: To investigate whether ultrasonography (US), as an objective imaging modality, can optimise the evaluation of disease activity in psoriatic arthritis (PsA) patients with concomitant fibromyalgia syndrome (FMS). METHODS: The study population included 156 consecutive PsA patients who were recruited prospectively and fulfilled the ClASsification criteria for Psoriatic ARthritis criteria. The patients underwent complete clinical evaluation including assessment of fulfilment of the 2016 fibromyalgia classification criteria. All of the patients underwent US evaluation including 52 joints, 40 tendons and 14 entheses. The US score was based on the summation of a semiquantitative score (including synovitis, tenosynovitis and enthesitis). Scoring was performed by a sonographer blinded to the clinical data. Spearman's correlation coefficient and multivariate linear regression models were used to examine the association of FMS with clinical and the US scores. RESULTS: Forty-two patients (26.9%) with coexisting PsA and FMS were compared with 114 (73.1%) PsA patients without FMS. Patients with PsA and FMS had significantly increased scores for clinical composite indices, including non-Minimal Disease Activity, Composite Psoriatic Disease Activity Index (CPDAI), Disease Activity for Psoriatic Arthritis (DAPSA) and Psoriatic Arthritis Disease Activity Score (PASDAS) (p<0.001). In contrast, the total US score and its subcategories were similar for those with and without FMS. The total US score significantly correlated with CPDAI, DAPSA and PASDAS (p<0.001) in the PsA without FMS but not in the PsA with FMS group. FMS was significantly associated with higher clinical scores (p<0.001) but not with the US score (multivariable linear regression models). CONCLUSIONS: US has significantly greater value than composite clinical scores in the assessment of disease activity in PsA patients with FMS.

Prevalence of COVID-19 and seroprevalence to SARS-CoV-2 in a rheumatologic patient population from a tertiary referral clinic in Israel.

BACKGROUND: It is unclear if the prevalence of COVID-19 in rheumatologic patients is similar to that of the general population. There are no reports of seroprevalence of SARS-CoV-2 in these patients. AIMS: To investigate prevalence of COVID-19 cases and seroprevalence among rheumatologic patients and the risk factors for infection. METHODS: A cross-sectional study in a rheumatologic population. An online questionnaire was sent on 31 April 2020. Blood samples from 20% sample of patients were drawn for SARS-CoV-2 antibodies. Patients were divided based on autoimmune (AI) diagnosis. Prevalence of COVID-19 by nasopharyngeal swab and by serology (seroprevalence) was compared to national data. Risk factors for infection of SARS-CoV-2 were assessed. RESULTS: The study group included 1204 patients, 74.5% had an AI diagnosis. The prevalence of COVID-19 was 0.16% in the rheumatologic patient population and 0.22% in the AI group, which was not different from prevalence in Israel on 4 May 2020 (0.18%, P = 0.912 and P = 0.759 respectively). Serologic tests were performed in 242 patients, of which five were found positive pointing to a seroprevalence of 2.07%. Exposure to a known COVID-19 patient was the only significant risk factor for being positive by swab or by serology. AI diagnosis, immunosuppression, corticosteroid, hydroxychloroquine did not influence the risk. CONCLUSIONS: The prevalence of COVID-19 in a population of rheumatologic patients was similar to that of the general population. Mild/asymptomatic cases may be prevalent according to serologic tests. The major risk factor for infection is exposure to a known case of COVID-19, and immunosuppression did not play a role in the risk of infection.

What can we learn from simulation-based training to improve skills for end-of-life care? Insights from a national project in Israel.

BACKGROUND: Simulation-based training improves residents' skills for end-of-life (EOL) care. In the field, staff providers play a significant role in handling those situations and in shaping practice by role modeling. We initiated an educational intervention to train healthcare providers for improved communication skills at EOL using simulation of sensitive encounters with patients and families. METHODS: Hospital physicians and nurses (n = 1324) attended simulation-based workshops (n = 100) in a national project to improve EOL care. We analyzed perceptions emerging from group discussions following simulations, from questionnaires before and after each workshop, and from video-recorded simulations using a validated coding system. We used the simulation setting as a novel tool for action research. We used a participatory inquiry paradigm, with repetitive cycles of exploring barriers and challenges with participants in an iterative pattern of observation, discussion and reflection - including a description of our own responses and evolution of thought as well as system effects. RESULTS: The themes transpiring included lack of training, knowledge and time, technology overuse, uncertainty in decision-making, poor skills for communication and teamwork. Specific scenarios demonstrated lack of experience at eliciting preferences for EOL care and at handling conflicts or dilemmas. Content analysis of simulations showed predominance of cognitive utterances - by an order of magnitude more prevalent than emotional expressions. Providers talked more than actors did and episodes of silence were rare. Workshop participants acknowledged needs to improve listening skills, attention to affect and teamwork. They felt that the simulation-based workshop is likely to ameliorate future handling of EOL situations. We observed unanticipated consequences from our project manifested as a field study of preparedness to EOL in nursing homes, followed by a national survey on quality of care, leading to expansion of palliative care services and demand for EOL care education in various frameworks and professional areas. CONCLUSIONS: Reflective simulation exercises show barriers and paths to improvement among staff providers. When facing EOL situations, physicians and nurses use cognitive language far more often than emotions related expressions, active listening, or presence in silence. Training a critical mass of staff providers may be valuable to induce a cultural shift in EOL care.

[Recurrent hospitalizations due to false positive troponin in a patient presenting with chest pain].

A 58 year old male patient was hospitalized numerous times due to an elevated troponin I level in spite of the absence of specific chest pain and ischemic changes on ECG. The patient had undergone two coronary angiography procedures and numerous cardiac studies without evidence of ischemic heart disease. The elevated troponin level remained unchanged in between hospitalizations while the patient was asymptomatic. Further workup revealed that the troponin I level was normal when tested with an alternative laboratory kit. The troponin T level was also normal. This case report underscores the problematic nature of relying on an elevated troponin level as the sole component in the diagnosis of coronary disease.

Termination of pregnancy due to fetal abnormalities performed after 23 weeks' gestation: analysis of indications in 144 cases from a single medical center.

BACKGROUND/AIMS: To assess the indications for late termination (> or =23 weeks' gestation) of pregnancy (LTOP), and to evaluate the rate of cases potentially diagnosable earlier. METHODS: Cases of singleton pregnancy ending in LTOP due to fetal abnormalities in our institute between 1/1998 and 12/2005 were retrospectively reviewed. The women were divided into two groups according to the sequence of events that led to LTOP: Group 1 - the first test indicating an abnormal finding was performed < or =23 weeks' gestation, but LTOP was performed >23 weeks; Group 2 - the first test indicating an abnormal finding was performed > or =23 weeks of gestation, or the fetal prognosis was not certain at the time of diagnosis and there was a medical recommendation to continue investigation. RESULTS: There were 144 cases of LTOP (average gestational age 26.2 +/- 3.4 weeks). More than 70% of the cases were aborted because of chromosomal/genetic indication in Group 1; many of them could have been detected earlier in pregnancy, while about 80% of the cases were aborted because of structural abnormalities in Group 2 (p < 0.001). The structural anomaly could have been diagnosed earlier in 56 cases ( approximately 74%) if the pregnant woman had undergone an earlier anomaly scan. In another 13 cases (9%), fetal prognosis was not certain and continuing prenatal investigation was required. CONCLUSIONS: The most common indications for LTOP were structural abnormalities (91 cases, 70%) which included the central nervous system (26 cases, 29%), cardiac abnormalities (24 cases, 26%), and multiple malformations (18 cases, 20%). The diagnosis of fetal anomaly could have been made earlier in more than half of the pregnant women undergoing LTOP.
