[PMID: 38825182 DOI: 10.1016/j.redare.2024.05.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/04/2023] [Revised: 11/21/2023] [Accepted: 12/12/2023] [Indexed: 06/04/2024]
Abstract
PURPOSE To demonstrate the utility of machine learning models for predicting difficult airways using clinical and ultrasound parameters. METHODS This is a prospective non-consecutive cohort of patients undergoing elective surgery. We collected as predictor variables age, sex, BMI, OSA, Mallampatti, thyromental distance, bite test, cervical circumference, cervical ultrasound measurements, and Cormack-Lehanne class after laryngoscopy. We univariate analyzed the relationship of the predictor variables with the Cormack-Lehanne class to design machine learning models by applying the random forest technique with each predictor variable separately and in combination. We found each design's AUC-ROC, sensitivity, specificity, and positive and negative predictive values. RESULTS We recruited 400 patients. Cormack-Lehanne patients ≥ III had higher age, BMI, cervical circumference, Mallampati class membership ≥ III, and bite test ≥ II and their ultrasound measurements were significantly higher. Machine learning models based on physical examination obtained better AUC-ROC values than ultrasound measurements but without reaching statistical significance. The combination of physical variables that we call the "Classic Model" achieved the highest AUC-ROC value among all the models [0.75 (0.67-0.83)], this difference being statistically significant compared to the rest of the ultrasound models. CONCLUSIONS The use of machine learning models for diagnosing VAD is a real possibility, although it is still in a very preliminary stage of development. CLINICAL REGISTRY ClinicalTrials.gov: NCT04816435.

Usefulness of thoracic ultrasound in the assessment of removal of indwelling pleural catheter in patients with malignant pleural effusion. RADIOLOGIA 2024; 66 Suppl 1:S24-S31. [PMID: 38642957 DOI: 10.1016/j.rxeng.2023.04.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/24/2022] [Accepted: 04/20/2023] [Indexed: 04/22/2024]
Abstract
INTRODUCTION There are no defined criteria for deciding to remove a non-functioning indwelling pleural catheter (IPC) when lung re-expansion on chest X-ray is incomplete. Chest computed tomography (chest CT) is usually used. The objective of this work is to validate the usefulness of chest ultrasound performed by a pulmonologist and by a radiologist compared to chest CT. PATIENTS AND METHODS Prospective, descriptive, multidisciplinary and multicenter study including patients with malignant pleural effusion and non-functioning IPC without lung reexpansion. Decisions made on the basis of chest ultrasound performed by a pulmonologist, and performed by a radiologist, were compared with chest CT as the gold standard. RESULTS 18 patients were analyzed, all of them underwent ultrasound by a pulmonologist and chest CT and in 11 of them also ultrasound by a radiologist. The ultrasound performed by the pulmonologist presents a sensitivity of 60%, specificity of 100%, PPV 100% and NPV 66% in the decision of the correct removal of the IPC. The concordance of both ultrasounds (pulmonologist and radiologist) was 100%, with a kappa index of 1. The 4 discordant cases were those in which the IPC was not located on the ultrasound. CONCLUSIONS Thoracic ultrasound performed by an expert pulmonologist is a valid and simple tool to determine spontaneous pleurodesis and remove a non-functioning IPC, which would make it possible to avoid chest CT in those cases in which lung reexpansion is observed with ultrasonography.

Abstract
OBJECTIVE The objective was to describe the characteristics of the use of clinical ultrasound in two health centers (SC) of Health Area VII of the Region of Murcia (CS Murcia-Sur and CS Floridablanca). DESIGN Observational, descriptive, longitudinal, prospective and multicenter study. SITE: CS Murcia-Sur and CS Floridablanca (Health Area VII of the Region of Murcia). PARTICIPANTS One hundred and thirty-five patients were included. INTERVENTIONS Performance of clinical ultrasound in the primary care (PC) consultation. MAIN MEASUREMENTS Demographic variables (age, sex), as well as clinical variables (reason for consultation, type of ultrasound, results, referrals to the second hospital level, degree of diagnostic agreement) were collected. RESULTS One hundred and thirty-five patients were included, more than 50% were female. The main reason for consultation was musculoskeletal and soft tissue symptoms (44.4%), followed by digestive symptoms (21.5%). 44.4% of the ultrasounds were classified as normal, while pathological findings were found in 55.6%. Confirmatory tests were requested in 43.7% and the findings were confirmed in 67% of the patients. CONCLUSIONS The use of ultrasound in PC allows to show the high prevalence of pathological findings in the examination of patients. In a technique that helps the clinician in his diagnostic-therapeutic process. The integration of clinical ultrasound in the PC consultation can save complementary studies and referrals to a second level of care. Its implementation in PC requires proper training of professionals.

ENFERMERIA INTENSIVA 2024:S2529-9840(23)00071-X. [PMID: 38453623 DOI: 10.1016/j.enfie.2023.10.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2023] [Revised: 08/14/2023] [Accepted: 10/02/2023] [Indexed: 03/09/2024]
Abstract
AIM To compare the efficacy of conventional puncture versus ultrasound-guided puncture for arterial blood gas sampling in adults. METHOD A search protocol was developed and applied to three databases (Medline, Cochrane, and Dialnet). Clinical trials published between January 2013 and January 2023, in Spanish or English, were considered. Outcomes in terms of first-attempt success, number of attempts until success, time taken, self-reported iatrogenic pain, and patient or professional experience were collected. The risk of bias for each included study was assessed. RESULTS Five randomized clinical trials were selected, with sample sizes ranging from 50 to 238 adult patients treated in emergency settings. Three out of four studies showed higher first-attempt success rates when using ultrasound, and 2 out of 4 studies reported a decrease in iatrogenic pain. Discrepant findings were observed among the studies in terms of time taken and the number of attempts required for success. CONCLUSIONS Although current evidence is limited and the findings are heterogeneous, ultrasound-guided arterial puncture may have advantages over conventional puncture in terms of first-attempt success and in reducing iatrogenic pain.

Utility of applying a diagnostic algorithm in giant cell arteritis based on the level of clinical suspicion. Med Clin (Barc) 2024:S0025-7753(23)00755-8. [PMID: 38278759 DOI: 10.1016/j.medcli.2023.11.021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2023] [Revised: 11/16/2023] [Accepted: 11/18/2023] [Indexed: 01/28/2024]
Abstract
INTRODUCTION To reach the diagnosis of giant cell arteritis (GCA), signs, symptoms, laboratory tests, imaging findings, and occasionally anatomopathological results from temporal artery biopsy are evaluated. This study describes the results of an algorithm analysis based on clinical and ultrasound evaluation of patients with suspected GCA, highlighting its diagnostic utility by contrasting its use in different clinical suspicion scenarios. METHOD Prospective multicenter study evaluating patients referred with suspected GCA through a preferential circuit (fast track), grouping them according to low or high clinical suspicion of GCA. Each of these scenarios is evaluated by biopsy and ultrasound for all patients, resulting in positive, indeterminate, or negative outcomes, yielding six possible groups. Potential areas of improvement are explored, emphasizing that, following a negative or indeterminate ultrasound, 18-FDG-PET-CT could be recommended. We analyze the results and application of a diagnostic algorithm, confirming its efficiency and applicability based on whether there is high or low clinical suspicion. RESULTS Sixty-nine patients (41 in the high suspicion group and 28 in the low suspicion group). There were 41 new diagnoses of GCA: 35 in the high suspicion group and 6 in the low suspicion group. Using ultrasound alone, the initial algorithm has an overall diagnostic efficiency of 72.5%, which improves to 80.5% when including 18F-FDG-PET/CT. The negative predictive value of ultrasound in patients with low clinical suspicion is 84.6%, and the positive predictive value of ultrasound in patients with high suspicion is 100%, improving sensitivity from 57.1% to 80.8% with 18F-FDG-PET/CT in this scenario. Temporal artery biopsy was performed on all patients, with no differences in sensitivity or specificity compared to ultrasound. In cases where all three tests - ultrasound, biopsy, and 18F-FDG-PET/CT - are performed, sensitivity increases to 92.3% in patients with high clinical suspicion. CONCLUSION In situations of high clinical suspicion, the algorithm provides sufficient information for the diagnosis of GCA if ultrasound is positive. A negative ultrasound is sufficient to rule out the diagnosis in the context of low clinical suspicion. 18-FDG-PET-CT may be useful in patients with high suspicion and negative or indeterminate ultrasound results.

Abstract
Ultrasound is an essential diagnostic tool in critically ill patients with extracorporeal membrane oxygenation (ECMO). With it, we can make an anatomical and functional (cardiac, pulmonary and vascular) evaluation which allows us to execute an adequate configuration, guides implantation, helps clinical monitorization and detects complications, facilitates withdrawal and complete post-implant evaluation. In patients with ECMO as respiratory support (veno-venous), thoracic ultrasound allows monitoring pulmonary illness evolution and echocardiography the evaluation of biventricular function, especially right ventricle function, and cardiac output to optimize oxygen transport. In ECMO as circulatory support (veno-arterial), echocardiography is the guide of hemodynamic monitoring, allows detecting the most frequent complications and helps the weaning. In ECMO teams, for a proper management of these patients, there must be trained intensivists with advanced knowledge on this technique.

Abstract
INTRODUCTION AND AIMS Cystic fibrosis (CF) is a genetic disease whose gastrointestinal compromise mainly involves the pancreas, bile ducts, and liver. Our aim was to analyze abdominal ultrasound findings. METHODS A retrospective, descriptive study was conducted on adults (patients ≥ 16 years of age) diagnosed with CF, within the time frame of 2006-2019. Clinical and genetic parameters, body mass index, forced expiratory volume in one second, pancreatic insufficiency, CF-related diabetes, cirrhosis secondary to CF, and abdominal ultrasound images were analyzed. RESULTS Seventy patients, 39 of whom were men (55.8%), had a mean age of 27 years and a mean body mass index of 21.3 ± 2.8 kg/m2 (r: 17-30.9). Forty-seven (67.1%) presented with pancreatic insufficiency, 6 (8.5%) with cirrhosis secondary to CF, and 21 (30%) had CF-related diabetes. Median forced expiratory volume in one second was 47% and the F508del mutation was found in 56.1%. Images of the pancreas: no pathologic findings in 49 (70%), increased echogenicity in 18 (25.7%), and cysts in 3 (4.3%). Gallbladder images: microgallbladder in 3 (4.2%), biliary sludge in 2 (2.8%), gallstones in 7 (10%), and a history of cholecystectomy in 4 (5.8%). Liver and spleen images: no pathologic findings in 47 (67.2%), homogeneous hepatomegaly with splenomegaly in 2 (2.8%), a heterogeneous pattern of the parenchyma in 11 (15.8%), increased echogenicity in 4 (5.7%), and heterogeneous echo patterns, lobulated liver contour, and splenomegaly in 6 (8.5%). CONCLUSION Abdominal ultrasound is a safe, low-cost technique that enables the identification of some degree of chronic liver and pancreatic diseases, improving the approach and follow-up decisions in adult patients with CF.

Interobserver reliability of classifying shoulder calcific tendinopathy on plain radiography and ultrasound. Rev Esp Cir Ortop Traumatol (Engl Ed) 2023:S1888-4415(23)00263-1. [PMID: 38110150 DOI: 10.1016/j.recot.2023.12.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2023] [Revised: 11/22/2023] [Accepted: 12/11/2023] [Indexed: 12/20/2023] Open
Abstract
INTRODUCTION Shoulder calcific tendinopathy is a frequent cause of shoulder pain. Diagnosis is usually based on ultrasound (US) and/or X-ray. US is considered an inherently operator-dependent imaging modality and, interobserver variability has previously been described by experts in the musculoskeletal US. The main objective of this study is to assess the interobserver agreement for shoulder calcific tendinopathy attending to the size, type, and location of calcium analyzed in plain film and ultrasound among trained musculoskeletal radiologists. MATERIAL AND METHODS From June 2018 to May 2019, we conducted a prospective study. Patients diagnosed with shoulder pain related to calcific tendinopathy were included. Two different experienced musculoskeletal radiologists evaluated independently the plain film and the US. RESULTS Forty patients, with a mean age of 54.6 years, were included. Cohen's kappa coefficient of 0.721 and 0.761 was obtained for the type of calcium encountered in plain film and the US, respectively. The location of calcification obtained a coefficient of 0.927 and 0.760 in plain film and US, respectively. The size of the calcification presented an intraclass correlation coefficient (ICC) of 0.891 and 0.86 in plain film and US respectively. No statistically significant differences were found in either measurement. CONCLUSION This study shows very good interobserver reliability of type and size measurement (plain film and US) of shoulder calcifying tendinopathy in experienced musculoskeletal radiologists.

Abstract
Placenta accreta spectrum (PAS) disorders (with increasing order of the depth of invasion: accreta, increta, percreta) are quite challenging for the purpose of diagnosis and treatment. Pathological examination or imaging evaluation are not very dependable when considered as stand-alone diagnostic tools. On the other hand, timely diagnosis is of great importance, as maternal and fetal mortality drastically increases if patient goes through the third phase of delivery in a not well-suited facility. A multidisciplinary approach for diagnosis (incorporating clinical, imaging, and pathological evaluation) is mandatory, particularly in complicated cases. For imaging evaluation, the diagnostic modality of choice in most scenarios is ultrasound (US) exam; patients are referred for MRI when US is equivocal, inconclusive, or not visualizing placenta properly. Herewith, we review the reported US and MRI features of PAS disorders (mainly focusing on MRI), going over the normal placental imaging and imaging pitfalls in each section, and lastly, covering the imaging findings of PAS disorders in the first trimester and cesarean section pregnancy (CSP).

Abstract
We report retrospectively a series of four cases involving the successful use of the recently described parascapular sub-iliocostalis plane block (PSIP), for lateral-posterior rib fractures. The efficacy of the PSIP block may potentially depend on different mechanisms of action: (1) direct action in the fracture site by craniocaudal myofascial spread underneath the erector spinae muscle (ESM); (2) spread to deep layers through tissue disruption caused by trauma, to reach the proximal intercostal nerves; (3) medial spread below the ESM, to reach the posterior spinal nerves; and (4) lateral spread in the sub-serratus (SS) plane to reach the lateral cutaneous branches of the intercostal nerves; while avoiding significant negative hemodynamic effects and other possible complications associated to other techniques leading that the PSIP may be considered an alternative in some clinical scenarios to the Erector Spinae Plane block or the Paravertebral block.

Abstract
INTRODUCTION Incidence of gallbladder polyps is 0,3-12%. It is important to differentiate pseudopolyps (cholesterol polyps, adenomyomatosis, inflammatory polyps), which do not have the capacity to become malignant, from true polyps (adenomas and adenocarcinomas). The main risk factors for malignancy are >6-10 mm, growth, sessile morphology, Indian ethnicity and primary sclerosing cholangitis. Ultrasound is the gold standard for diagnosis. Most polyps diagnosed by ultrasound are pseudopolyps. The main objective of this study is to analyse whether ultrasound is accurate for diagnosing true polyps in patients undergoing surgery for this reason. METHODS Retrospective observational study with prospective data entry of patients undergoing elective cholecystectomy for gallbladder polyps from 2007 to 2021. Surgery was indicated in symptomatic patients and in those with risk factors. The study has been approved by the Clinical Research Ethics Committee of our hospital. RESULTS We included 124 patients in our study. An elective laparoscopic cholecystectomy was performed in all of them. The mean age was 55,4 years and 61% were women. Of all patients, 65% were symptomatic at diagnosis. Only 3 patients had true polyps (2,4%). All of them were tubular adenomas. The rest of patients were false positives (97,6%). The adenoma size was 11, 6 and 5 mm, respectively. The surgical indication was due to polyp size or due to associated biliary symptoms. CONCLUSION Ultrasonography is not accurate for the diagnosis of gallbladder polyps. Validation of other complementary tests for the diagnosis of gallbladder polyps in asymptomatic patients could be relevant to avoid unnecessary surgeries.

Abstract
OBJECTIVE Calcific tendinopathy of the rotator cuff is a common condition caused by the deposition of calcium crystals in the tendons of the rotator cuff. This study aimed to analyze the effectiveness of ultrasound-guided puncture and aspiration in calcific tendinopathy of the should in 86 patients treated at our center and to determine the factors associated with poor prognosis after this treatment. MATERIAL AND METHODS This retrospective descriptive study included 86 patients with calcific tendinopathy of the rotator cuff treated with ultrasound-guided puncture and aspiration between 2015 and 2019 for whom clinical and radiological variables were collected 1, 3, 6, and 12 months after the procedure. RESULTS One year after treatment, 81.4% patients showed clinical improvement and 96.5% showed radiological improvement. Complications were observed in 34.9%; all complications were mild. CONCLUSIONS Ultrasound-guided puncture and aspiration is an effective treatment for calcific tendinopathy of the shoulder, resulting in a high rate of clinical and radiological improvement and a low rate of minor complications. This technique has additional advantages, such as interaction with the patient and the lack of ionizing radiation.

Abstract
OBJECTIVE Our aim was to add to the small but growing body of evidence on the effectiveness of ultrasound-guided Achilles intratendinous hyperosmolar dextrose prolotherapy and introduce a novel, preceding step of paratenon hydrodissection with lidocaine in patients with chronic Achilles tendinosis resistant to rehabilitation therapy. METHODS We conducted a longitudinal, observational study on 27 consecutive patients diagnosed with Achilles tendinosis, in whom conservative treatment, ie, physiotherapy or shock wave therapy, had failed. A 2% lidocaine paratenon anesthesia and hydrodissection was followed by ultrasound-guided, intratendinous injections of 25% glucose every 5 weeks. Visual analogue scales (VAS) were used for pain assessment at rest, for activities of daily living, and after moderate exercise at the begining and at the end of the treatment. Moreover, tendon thickness and vascularisation were recorded at baseline and final treatment consultation. Effectiveness was estimated from scoring and relative pain reduction using a 95% CI. The non-parametric Wilcoxon test and a general linear model for repeated measures were applied. Statistical significance was established as p < 0.05. RESULTS A median of 5 (1-11) injection consultations per patient were required. Pain scores decreased significantly in all three conditions (p < 0.001). Relative reductions were 75% in pain at rest (95% CI;61-93%), 69% in pain with daily living activities (95% CI; 55-83%), and 70% in pain after moderate exercise (95% CI; 57-84%). Tendon neo-vascularisation was significantly reduced (p < 0.001). We did not observe significant changes in tendon thickness (p = 0.083). CONCLUSIONS Achilles tendinosis treatment with paratenon lidocaine hydrodissection and subsequent prolotherapy with hyperosmolar glucose solution is safe, effective, inexpensive, and virtually painless with results maintained over time.

Abstract
Comprehensive ultrasound assessment has become an essential tool to facilitate the diagnosis and therapeutic management of critically ill patients with acute respiratory failure (ARF). There is evidence supporting the use of ultrasound for the diagnosis of pneumothorax, acute respiratory distress syndrome, cardiogenic pulmonary edema, pneumonia and acute pulmonary thromboembolism, and in patients with COVID-19. In addition, in recent years, the use of ultrasound to evaluate responses to treatment in critically ill patients with ARF has been developed, providing a noninvasive tool for titrating positive end-expiratory pressure, monitoring recruitment maneuvers and response to prone position, as well as for facilitating weaning from mechanical ventilation. The objective of this review is to summarize the basic concepts on the utility of ultrasound in the diagnosis and monitoring of critically ill patients with ARF.

Abstract
Point-of-care ultrasound (POCUS) is a sensitive, specific tool for early diagnosis of diaphragm pathology in critically ill patients. We report the case of a patient with a history of iatrogenic diaphragmatic hernia who was admitted to the Resuscitation Unit after an emergency exploratory laparotomy. As the diagnosis of diaphragmatic hernia had already been confirmed, we determined the POCUS features that establish the diagnosis of diaphragmatic hernia: (1) normal bilateral diaphragmatic shortening fraction; (2) decreased diaphragmatic excursion; and (3) cephalic position of the diaphragmatic dome (4) greater in supine than in sitting position. We also outline a systematic ultrasound examination of the diaphragm and a POCUS-based differential classification of diaphragmatic dysfunction based on the functional integrity of the peripheral muscle and central diaphragmatic tendon in critically ill patients.

Abstract
We report the case of a paediatric patient who presented at the Emergency Department with severe pain in the right lower extremity caused by a scorpion sting. Analgesics were ineffective, so we decided to perform an ultrasound-guided popliteal block, which provided complete analgesia and allowed the patient to be followed up in the outpatient department, with no adverse effects. The sting of the species of scorpion found in Spain is not dangerous to human life; however, it causes self-limiting localised pain that lasts for 24-48h, and can be severe. The first-line treatment is effective analgesia. Regional anaesthesia techniques are useful in the control of acute pain, and are an example of effective collaboration between the Anaesthesiology and Emergency services.

Abstract
INTRODUCTION Ultrasound has been used to quantify and qualify muscle morphology in critically ill children and can detect changes in muscle thickness. The aim of this study was to assess the reliability of ultrasound measurement of muscle thickness in critically ill children and to compare the assessments made by an expert with those made by inexperienced sonographers. MATERIAL AND METHODS Cross-sectional observational study conducted in the paediatric intensive care unit of a tertiary care university hospital in Brazil. The sample included patients aged 1 month to 12 years who received invasive mechanical ventilation for at least 24 h. Ultrasound images of the biceps brachii/brachialis and quadriceps femoris were obtained by one experienced sonographer and several inexperienced sonographers. We assessed intrarater and inter-rater reliability by means of the intraclass correlation coefficient (ICC) and Bland-Altman plot analysis. RESULTS Muscle thickness was measured in 10 children with a mean age of 15.5 months. The mean thickness of the assessed muscles as 1.14 cm for the biceps brachii/brachialis (standard deviation [SD], 0.27) and 1.85 cm for the quadriceps femoris (SD, 0.61). The intrarater and inter-rater reliability were good for all sonographers (ICC > 0.81). The differences were small, there was no significant bias in the Bland-Altman plots and all measurements were within the limits of agreement, except for 1 measurement of biceps and quadriceps. CONCLUSION Sonography can be used in critically ill children to accurately assess changes in muscle thickness, even by different evaluators. More studies are needed to establish a standardised approach to the use of ultrasound for monitoring muscle loss in order to incorporate it in clinical practice.

Salivary gland ultrasound in clinical practice: What is its real usefulness? REUMATOLOGIA CLINICA 2023; 19:260-265. [PMID: 37147062 DOI: 10.1016/j.reumae.2022.09.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/23/2022] [Accepted: 09/13/2022] [Indexed: 05/07/2023]
Abstract
BACKGROUND Salivary gland ultrasound (SGU) provides information about structural gland abnormalities that can be graded and used for primary Sjögren's syndrome (pSS) diagnosis. Its potential role as a prognostic marker for detecting patients at high risk of lymphoma and extra-glandular manifestations is still under evaluation. We aim to assess the usefulness of SGU for SS diagnosis in routine clinical practice and its relationship with extra-glandular involvement and lymphoma risk in pSS patients. METHODS We designed a retrospective observational single-center study. Data was collected using the electronic health records of patients referred to an ultrasound outpatient clinic for evaluation over a 4-year period. Data extraction included demographics, comorbidities, clinical data, laboratory tests, SGU results, salivary gland (SG) biopsy, and scintigraphy results. Comparisons were made between patients with and without pathological SGU. The external criterion for comparison was the fulfillment of the 2016 ACR/EULAR pSS criteria. RESULTS A total of 179 SGU assessments were included from this 4-year period. Twenty-four cases (13.4%) were pathological. The most frequently diagnosed conditions prior to SGU-detected pathologies were pSS (9.7%), rheumatoid arthritis (RA) (13.1%), and systemic lupus (4.6%). One hundred and two patients (57%) had no previous diagnosis (sicca syndrome work-up); of these, 47 patients (46.1%) were ANA positive and 25 (24.5%) anti-SSA positive. In this study, the sensitivity and specificity of SGU for SS diagnosis were 48% and 98% respectively, with a positive predictive value of 95%. There were statistically significant relationships between a pathological SGU and the presence of recurrent parotitis (p=.0083), positive anti-SSB antibodies (p=.0083), and a positive sialography (p=.0351). CONCLUSIONS SGU shows high global specificity but low sensitivity for pSS diagnosis in routine care. Pathological SGU findings are associated with positive autoantibodies (ANA and anti-SSB) and recurrent parotitis.

Abstract
OBJECTIVE To present a series of patients with elastofibroma dorsi (ED) in order to recall the pathology and justify its diagnostic and therapeutic management in the primary care setting. MATERIALS AND METHODS Retrospective observational and longitudinal study of 12 patients with 18ED. Epidemiological, clinical and imaging characteristics were analysed. Treatment outcomes were assessed in terms of pain (VAS scale), shoulder function (Constant and Murley scale) and quality of life (EuroQol-5 dimension scale, EQ-5D). The mean follow-up of the cases was 60.5months (5years, range 1-161months). RESULTS Six patients were male and six were female, with a mean age at diagnosis of 59years. The diagnosis of suspicion in all cases was based in clinical and imaging findings. Only three required surgery. The results of all were satisfactory. CONCLUSIONS Both the diagnosis and the indication for treatment of an ED can be made in the primary care setting. In typical cases, which are the majority, the clinical history and an ultrasound study allow a diagnosis of certainty. The indication for conservative or surgical treatment depends on the informed patient. When there are diagnostic doubts or the patient wishes surgical resection of the tumour, the patient should be referred to a hospital specialist.

Abstract
OBJECTIVE To identify differential features between patients with seropositive and seronegative rheumatoid arthritis (RA). METHOD Prospective cohort study, including patients who were admitted for polyarthralgia. At baseline was performed: laboratory studies, X-rays of hands and feet, ultrasound of both hands with power Doppler technique, clinical data and clinimetry. In subsequent visits the definitive diagnosis of RA was established or not. It was considered as seronegative RA when patients were negative for both RF and ACPAs. RESULTS 746 patients were included, of which 128 (17.1%) ended with a final diagnosis of RA. Of these 128 patients, 87 (67.9%) were seropositive RA, while 41 (32%) were seronegative RA. The only feature that showed significant differences was the presence of tenosynovitis detected by ultrasound with a positive power Doppler signal, 13.7% of the patients with seropositive RA vs 41.6% of the patients with seronegative RA (p=0.0028). CONCLUSION The only differential feature of patients with seronegative RA was the higher proportion of tenosynovitis detected by ultrasound.

Abstract
INTRODUCTION Eco-guided interventionism has changed the way Physical Medicine and Rehabilitation specialists deal with musculoskeletal pain and other problems such as spasticity. The implementation of the Eco-Guided Intervention Units improves the results of the usual minimally invasive treatments in our speciality's clinical practice. The biggest drawback of this practice is the long learning curve and the difficulty of practice during training courses. OBJECTIVE To develop a system of phantoms that allow the practice of interventionism in anatomical models by shortening learning times and improving certainty by achieving the objective of interventionist practice. METHODS Describes the method of manufacturing three-dimensional models of joints with images obtained from computerized axial tomography, and their subsequent inclusion in gelatin's made molds, which allow to obtain phantoms, similar to real joint models, that allow to study using ultrasound techniques, and the practice of eco-guided interventionism. CONCLUSION Three-dimensional joint models made with gelatin are useful in the practice and learning of joint eco-guided interventionism techniques.

Abstract
BACKGROUND Pulmonary congestion is a strong predictor of mortality and cardiovascular events in chronic kidney disease (CKD); however, the effects of the mild form on functionality have not yet been investigated. The objective of this study was to assess the influence of mild pulmonary congestion on diaphragmatic mobility (DM) and activities of daily living (ADL) in hemodialysis (HD) subjects, as well as compare ADL behavior on dialysis and non-dialysis days. In parallel, experimentally induce CKD in mice and analyze the resulting pulmonary and functional repercussions. METHODS Thirty subjects in HD underwent thoracic and abdominal ultrasonography, anthropometric assessment, lung and kidney function, respiratory muscle strength assessment and symptoms analysis. To measure ADL a triaxial accelerometer was used over seven consecutive days. Twenty male mice were randomized in Control and CKD group. Thoracic ultrasonography, TNF-α analysis in kidney and lung tissue, exploratory behavior and functionality assessments were performed. RESULTS Mild pulmonary congestion caused a 26.1% decline in DM (R2=.261; P=.004) and 20% reduction in walking time (R2=.200; P=.01), indicating decreases of 2.23mm and 1.54min, respectively, for every unit increase in lung comet-tails. Regarding ADL, subjects exhibited statistically significant differences for standing (P=.002), walking (P=.034) and active time (P=.002), and number of steps taken (P=.01) on days with and without HD. In the experimental model, CKD resulted in increased levels of TNF-α on kidneys (P=.037) and lungs (P=.02), attenuation of exploratory behavior (P=.01) and significant decrease in traveled distance (P=.034). Thoracic ultrasonography of CKD mice showed presence of B-lines. CONCLUSION The mild pulmonary congestion reduced DM and walking time in subjects undergoing HD. Individuals were less active on dialysis days. Furthermore, the experimental model implies that the presence of pulmonary congestion and inflammation may play a decisive role in the low physical and exploratory performance of CKD mice.

Can ultrasound characteristics help in differentiating adenoma vs carcinoma in follicular thyroid neoplasms? RADIOLOGIA 2023; 65:22-31.

Abstract
INTRODUCTION AND OBJECTIVES Thyroid nodules frequently require ultrasound and Fine Needle Aspiration Cytology (FNAC) evaluation. However, FNA cytology does not allow differentiation between follicular adenoma and carcinoma on Bethesda type IV lesions. This situation leads to many unnecessary surgical procedures because it is not possible to assure the benignity of the lesions, even when most of the specimens correspond to adenomas or even other benign lesions. The objective is this study is to establish if there are any US characteristics that would help us to predict the risk of malignancy of nodules with a pathological diagnosis of follicular neoplasm in order to achieve a more conservative management for non-suspicious nodules. MATERIAL AND METHODS We studied 61 nodules in 61 patients (51 women and 10 men) that underwent thyroid surgery and had histopathological results of either follicular adenoma or carcinoma. Different US characteristics of the nodules were analysed (composition, echogenicity, margin, calcification status, the presence of halo and overall observer suspicion of malignancy) and were correlated with the histopathological analysis. RESULTS We have found a statistically significant association between the presence of calcifications, ill-defined borders and overall observer suspicion or impression (defined by well-known suspicious for malignancy ultrasonographic features, such as calcification, poorly defined margin, and a markedly hypoechoic solid nodule; and benign ultrasonographic features, such as predominantly cystic echogenic composition and the presence of a perinodular hypoechogenic halo) with follicular carcinoma. However all those features have shown low sensitivities in the present study (30%, 30% and 50%, respectively). On the other hand, the absence of halo sign has shown a sensitivity of 100% and a negative predictive value (NPV) of 100% in our study. CONCLUSIONS The presence of calcifications, ill-defined borders and the overall impression or suspicion of malignancy associate with a higher risk for follicular carcinoma in Bethesda type IV thyroid nodules but their absence do not allow to predict benignity in these nodules. Inversely, when a halo sign lesion is observed, benign follicular neoplasm should be considered.

Abstract
The generation of cell blocks (CBs) obtained from ultrasound-guided fine needle aspiration biopsies (USFNAB) is a well-established technique in breast and thyroid pathology, but is rarely used in dermatology. We reviewed CBs obtained from USFNAB of skin lesions, which were categorized as malignant skin tumors, benign skin tumors, inflammatory skin tumors or deposit skin diseases. The diagnostic yield of each category was compared to histopathology. The USFNAB of 51 skin lesions was processed into CBs. There was overall agreement between histopathology and CBs in 84.31% of cases. Diagnostic group concordance for benign, malignant as well as inflammatory and deposit skin lesions were 69.2%, 93.7% and 86.3% respectively. Cell block generation from USFNAB aspirates of skin lesions should be considered as part of the dermatologic diagnostic armamentarium. Further experience is needed to better understand for which types of dermatologic lesions it would be clearly indicated.
