RESUMEN

Background: The attentive management of rheumatoid arthritis (RA) has attracted particular attention. The German 7-joint Ultrasound (US-7) is the first scoring system that combines bone erosions and soft tissue lesions in a single composite scoring system. This study aimed to assess the correlation between US-7 and Disease Activity Score Using 28 Joint Counts (DAS28) in clinically active RA patients. The efficacy of a novel ultrasound score-based system, the US-9 score (joints assessed with US-7 plus knees), was also compared with the standard US-7 score. Methods: All the RA patients referred to the outpatient rheumatology clinic of Ghaem Hospital, Mashhad, Iran, during 2019-2020 were included. 28 joints were clinically examined to calculate DAS28. Nine joints were assessed comprising the German US-7 plus knees using grayscale ultrasonography (GSUS) and power Doppler ultrasonography (PDUS). Retrieved data were analyzed by SPSS software, version 22. The Spearman Correlation test was used to find the correlation between DAS28 and ultrasonographic findings. The statistical significance level was set at P<0.05. Results: This study was composed of thirty-five RA patients with a mean age of 49.1±12.0 years. US-7 synovitis scores in GSUS and PDUS were significantly correlated with DAS28 (P=0.02, r=0.38 and P=0.003, r=0.48, respectively). US-9 synovitis scores in GSUS and PDUS were also significantly correlated with DAS28 (P=0.003, r=0.49 and P=0.006, r=0.45, respectively). The synovitis score measured by GSUS was significantly correlated with the GSUS knee synovial score (P=0.01, r=0.42). Conclusion: Ultrasound assessment of large joints such as knees can be an effective approach to determining RA severity. However, it can be proposed that adding more involved joints into the sonographic assessment does not necessarily provide a better clinical correlation.

RESUMEN

BACKGROUND AND AIMS: Thromboembolism complication is considered the most common complication associated with the treatment of endovascular. This systematic review and meta-analysis aimed to assess the studies investigating the effect of glycoprotein IIb/IIIa inhibitor agents on thromboembolic complications during endovascular aneurysm coiling. MATERIALS AND METHODS: This systematic review investigated the outcome of the use of three glycoprotein IIb/IIIa inhibitor agents (ie abciximab, tirofiban, and eptifibatide) on the thromboembolic complications during endovascular aneurysm coiling. The electronic databases of PubMed, Web of Science, Scopus, and Medline were searched up to 25 June 2021, using the keywords "Abciximab," "Tirofiban," and "Eptifibatide" incombination with "Thromboembolism Complication," "Aneurysms," and "Endovascular Aneurysm Coiling." RESULTS: A total of 21 articles were found to be eligible and included in this review. The rates of complete and partial recanalization were estimated to be 56% and 92% in patients who underwent abciximab and tirofiban therapy, respectively. Rupture aneurysms were found in the majority of patients. In general, the mortality rate of the patients treated for thromboembolic complications during endovascular treatment of cerebral aneurysms with glycoprotein IIb/IIIa inhibitors was found to be 4.8% (CI 95%:0.027-0.067; p < .005). The average remission rate in studies investigating thromboembolism was 91% (CI 95%:0.88-0.95, I2 : 65.65/p < .001). CONCLUSION: Based on the obtained results, a higher mean rate of complete recanalization by eptifibatide was found in studies in which abciximab or tirofiban were used, compared to other mentioned agents. Moreover, the amount of hemorrhage was reported to be less after using tirofiban rather than abciximab.

RESUMEN

In 2018, during our first clinical study on the kineticomyographic (KMG)-controlled bionic hand, we implanted three magnetic tags inside the musculotendinous junction of three paired extensor-flexor transferred tendons. However, the post-operative tissue adhesions affected the independent movements of the implanted tags and consequently the distinct patterns of the obtained signals. To overcome this issue, we modified our surgical procedure from a one-stage tendon transfer to a two-stage. During the first surgery, we created three tunnels using silicon rods for the smooth tendon gliding. In the second stage, we transferred the same three pairs of the forearm agonist-antagonist tendons through the tunnels and implanted the magnetic tags inside the musculotendinous junction. Compared to our prior clinical investigation, fluoroscopy and ultrasound evaluations revealed that the surgical modification in the current study yielded more pronounced independent movements in two specific magnetic tags associated with fingers (maximum 5.7 mm in the first trial vs. 28 mm in the recent trial with grasp and release) and thumb (maximum 3.2 mm in the first trial vs. 9 mm in the current trial with thumb flexion-extension). Furthermore, we observed that utilizing the flexor digitorum superficialis (FDS) tendons for the flexor component in finger and thumb tendon transfer resulted in more independent movements of the implanted tags, compared with the flexor digitorum profundus (FDP) in the prior research. This study can help us plan for our future five-channel bionic limb design by identifying the gestures with the most significant independent tag displacement.

RESUMEN

BACKGROUND: Prostate-specific membrane antigen (PSMA) can provide a prostate cancer (PCa) detection approach in positron emission tomography (PET) using Food and Drug Administration (FDA)-approved PSMA-11 peptide. There are some studies evaluated magnetic-nanoprobes for PSMA detection by MRI, using non-FDA-approved ligands including antibodies or peptides, which are not as specific as PSMA-11. PURPOSE: To assess targeted iron oxide nanoparticles (IONPs) by PSMA-11 peptides as a potential specific nano-molecular probes to investigate a PSMA+ PCa-xenograft model by MRI. STUDY TYPE: Prospective. ANIMAL MODEL: Twenty male C57BL6 nude mice induced subcutaneously PSMA+ LNCaP cell line tumor. FIELD STRENGTH/SEQUENCE: 1.5 T, T2 -W Fast Spin echo and T2 *-W Gradient echo. ASSESSMENT: Coated IONPs with Carboxymethylated-dextran (DNPs) and with bovine serum albumin (BNPs), as well as, targeted DNPs with PSMA-11-HYNIC peptide (TDNPs) and targeted BNPs with PSMA-11-HBED peptide (TBNPs) were injected intravenously with dose 2.8 mg Fe/kg. Coronal T2 -W and the T2 *-W images were obtained before and 4 hours and 6 hours post-injection. Signal intensity (SI) and relative signal enhancement (RSE) were computed in two- and three-dimensional analyses. Histological analysis of tumors was evaluated, and the Fe distribution within the body based on atomic absorption spectroscopy was calculated. STATISTICAL TESTS: One-way ANOVA followed by Tukey's multiple comparison test, Paired-samples T-test, P < 0.05 was considered significant. RESULTS: A reduction in T2 -W SI was achieved as 22 ± 7%, 59 ± 3%, 65 ± 5%, and 78 ± 3% respectively for BNPs, TBNPs, DNPs, and TDNPs 6 hours post-injection. The most difference between targeted and non-targeted groups was observed at 6 hours for PSMA-11-HBED, and at 4 hours for PSMA-11-HYNIC. RSE indicated 88.6 ± 3.1% and 80.7 ± 3.2% enhanced contrast between tumor and muscle region for TBNPs and TDNPs on T2 *-W images. CONCLUSIONS: Both TBNPs and TDNPs are promising novel nano-molecular probes for PSMA+ PCa tumor detection. The injection dose of non-targeted IONPs can be reduced by using targeted nanoprobes three times for BNPs and two times for DNPs. EVIDENCE LEVEL: 1 TECHNICAL EFFICACY: Stage 1.

RESUMEN

Chronic granulomatous disease (CGD) is a rare primary immunodeficiency disorder that is characterized by deficiencies in the phagocytes capacity to eliminate ingested microorganisms, which frequently causes bacterial and fungal infections. The extensive involvement of the lungs, ribs, and vertebrae that is complicated by multiple abscesses from aspergillosis is rare. in this study, we report a 13-year-old boy with CGD who experienced concurrent pneumonia, rib osteomyelitis, spondylodiscitis, paravertebral, and epidural abscesses as a result of Aspergillus flavus infection with associated computed tomography scan and magnetic resonance imaging findings. Patients with CGD are susceptible to Aspergillus infection. Correct diagnosis based on clinical and paraclinical findings as well as choosing the best treatment regimen is essential for achieving a favorable outcome.

RESUMEN

Background: One controversial question in Carpal Tunnel Syndrome (CTS) diagnosis is whether magnetic resonance imaging (MRI) and Ultrasound (US) imaging tools have any relationship with electrodiagnostic (EDX) study. The objective of this study is to determine the possible correlation between MRI and US measurements with EDX parameters. Methods: Both US and MRI of the median nerve were simultaneously performed in 12 confirmed CTS wrists, at two levels of forearm distal fold (proximal) and the hook of the hamate (distal), to measure various anatomic parameters of the nerve. EDX parameters of median motor distal latency (DL) and median sensory proximal latency (PL) were evaluated in milliseconds. Results: Nerve cross-sectional area (CSA), measured by MRI, correlated with sensory PL at distal level (p = 0.015). At proximal level MRI, nerve width and width to height ratio also correlated with motor DL (p = 0.033 and 0.021, respectively). Median nerve CSA proximal to distal ratio correlated with sensory PL (p = 0.028) at MRI. No correlation was found between US and EDX measurements. Conclusions: Median nerve MRI measurement of nerve CSA at hook of the hamate (distal) level or CSA proximal to distal ratio correlated with EDX parameter of sensory PL. On the other hand, nerve MRI width and width to height ratio at distal level correlated with motor DL in EDX. Level of Evidence: Level III (Diagnostic).

RESUMEN

Background: Tethered cord syndrome (TCS) is a type of occult spinal dysraphism, which necessitates early detection as an essential component of patient management in reducing complications. This study aimed to compare the findings of spinal cord ultrasonography between TCS patients and healthy individuals. Methods: The current study is a case-control study of patients who were admitted to the Akbar and Ghaem Hospitals (Mashhad, Iran) in 2019. The study population comprised 30 children with TCS aged under two years old, and the control group included 34 healthy peers of the same age. The maximum distance of the spinal cord from the posterior canal wall was measured in millimeters using ultrasonography. Demographic and sonographic findings of each participant were recorded in checklists, which were then entered into SPSS software. P values less than 0.05 were considered statistically significant. Results: The study included 30 children with TCS and 34 healthy individuals with a mean age of 7.67±6.39 months. TCS patients had a significantly shorter maximum distance of the spinal cord from the posterior wall of the spinal canal than the control group (1.75±0.62 mm vs. 2.79±0.76, P<0.001). After performing corrective surgery, the TCS patients indicated significant improvement in this interval (1.57±0.54 mm to 2.95±0.49 mm, respectively, P=0.001). Conclusion: In comparison to children without TCS, the spinal cord was substantially closer to the posterior canal wall in TCS patients. However, these outcomes were improved significantly in patients after surgery.

RESUMEN

Aim: The accuracy of ultrasound findings in predicting the incidence of morbidly adherent placenta has been evaluated previously. In this study, we assessed the sensitivity and specificity of different quantitative findings of color Doppler and grayscale ultrasonography in predicting morbidly adherent placenta. Material and methods: In this prospective cohort study, all pregnant women over 20 weeks of gestational age with anterior placenta and a history of previous cesarean section were evaluated for inclusion. Various ultrasound findings were measured. The non-parametric receiver operating characteristic curves, the area under the curve, and the cut-off values were assessed. Results: A total of 120 patients were ultimately included for analysis, of whom 15 had morbidly adherent placenta. The two groups were significantly different regarding the number of vessels. Based on color Doppler ultrasonography, in predicting the morbidly adherent placenta, more than two intraplecental echolucent zones with color flow had 93% and 98% sensitivity and specificity, respectively. According to grayscale ultrasonography, more than thirteen intraplacental echolucent zones had the sensitivity and specificity of 86% and 80% in predicting morbidly adherent placenta, respectively. Echolucent zone >11 mm at non-fetal surface had a sensitivity of 93% and a specificity of 66% in detecting morbidly adherent placenta. Conclusions: According to the results, the quantitative findings of color Doppler ultrasound have considerable sensitivity and specificity in detecting morbidly adherent placenta. More than two echolucent zones with color flow are recommended as the main diagnostic parameter indicating the presence of morbidly adherent placenta with a sensitivity of 93% and a specificity of 98%.

RESUMEN

Introduction: Cervical adenopathy can be involved in various pathological processes. This study aimed to evaluate the ultrasound classification of cervical adenopathy (A-RADS) to choose the appropriate approach. Materials and Methods: This cross-sectional study was conducted among 294 patients with cervical adenopathy at Mashhad University of Medical Sciences during 2020-2021. The data of the long axis diameter, short axis diameter, shape, border, vascular pattern, presence of calcification and changes in cyst/necrosis, cortical echogenicity, hilum visibility, and location of involved lymph nodes were extracted. Lymph nodes was classified into four normal, reactive, suspicious & lymphoid disorders, and metastatic groups, based on ultrasound appearance (Adenopathy-reporting and data system). Diagnostic methods included follow-up, core needle biopsy (CNB), and fine needle aspiration (FNA), and surgical results. After determining the final diagnosis, demographic, sonographic, and pathological data were analyzed at a significance level of p<0.05. Results: Of 294 patients, 185 were benign, and 109 were malignant. There were no significant differences in the location, long axis diameter, shape, cystic or necrotic changes, calcification, and margins of the lymph nodes between the benign and malignant groups. The enlarged short axis diameter, invisible hilum with isoechoic cortex, and non-hilar vascularity were significantly higher in the malignant group (p<0.001). The malignancy rate was 8.7% in reactive cases, 48.5% in lymphoid disorders, and 90% in metastatic nodes. Conclusion: The results of this study shows that cervical lymph nodes can be classified based on short axis diameter, cortex and hilum echo-texture and vascular pattern into normal, reactive, suspicious & lymphoid disorders, and metastatic, which have a high concordance with pathologic results.

RESUMEN

Myelolipoma is a benign tumor containing mature adipose cells and a combination of myeloid and erythroid elements. This tumor is typically found in the adrenal glands; however, it has been detected outside the adrenal glands in rare cases. We report an extremely rare case of myelolipoma in the lumbar spine causing significant neural compression due to the involvement of the posterior spinal elements. Given the significant neurological deficit, the patient was surgically managed as soon as possible. Extra-adrenal myelolipomas are rare lesions, and only one case has been reported in the spine so far. However, this diagnosis should be considered in cases with its characteristic imaging features.

RESUMEN

Background: The interest in ultrasonography (US) and magnetic resonance imaging (MRI) assessment of the patients with carpal tunnel syndrome (CTS) is growing. This paper aimed to find the correlation of postoperative changes in these modalities' parameters with clinical outcomes. Methods: Boston CTS questionnaire-symptom severity (BQ-SS), Boston CTS questionnaire-functional status (BQ-FS), and visual analog scale (VAS) questionnaires (for pain, paresthesia, and grip weakness assessment) were used to evaluate clinical outcomes. Various imaging parameters of the median nerve and carpal tunnel were evaluated using US and MRI at two levels of the hook of the hamate (distal) and the pisiform (proximal) once preoperatively and then 3 months postoperatively. Corresponding US and MRI parameter measures were compared, and correlational analysis was performed between alteration of imaging findings and changes in clinical parameters postoperatively. Results: Patients' functional status (BQ-FS score) was positively correlated with the nerve width both in US and MRI at the proximal level (r = 0.457 and r = 0.453, respectively) and also with the MRI nerve circumference at the distal level (r = -0.482). Correlation between paresthesia and the nerve width was notable in MRI at the distal hook of the hamate level (r = -0.403). Grip weakness VAS score was correlated with the nerve width-to-height ratio (WHR) in US at the distal level (r = 0.432). Conclusions: Changes in US and MRI parameters of the median nerve width, circumference, and WHR were associated with clinical changes in patients with CTS after surgery.

RESUMEN

Sacrococcygeal chordoma is a rare malignant bone tumor. Although there are tough membranes such as the periosteum and presacral fascia (which resist transgression by the tumors), chordoma usually invades the rectal wall. The serious problem with these tumors is the late diagnosis and its high likelihood to become enlarged. The main treatment options for this tumor is surgical resection, radiotherapy, and chemotherapy. Due to the tumor vicinity to important organs such as bladder and its neurovascular structures, it makes surgical excision extremely challenging. The aim of this study is to describe a 50-year-old man with a giant sacrococcygeal mass. The novelty of this case report is the huge and unique size of the tumor which has not reported previously as well the special surgical approaches performed to remove the tumor.

RESUMEN

OBJECTIVES: Accurate detection and competent management of thyroid nodules, as a common disease, basically depends on the reliability of the ultrasonography (US) report. In this research, we evaluated inter and intra-observer variation among ultrasonography reporters, based on ACR-TIRADS. METHODS: In this retrospective study, 345 thyroid US images of 150 patients were reviewed. Three clinicians with at least 6-year experience in thyroid US reviewed the images twice at 6-8 weeks' intervals. Composition, echogenicity, shape, margin, and echogenic foci based on ACR-TIRADS were reported, independently. Inter and intra-observer variations were calculated based on Cohen's Kappa statistics. RESULTS: 345 ultrasonography images of 150 patients with thyroid nodules (83 women and 67 men) with a mean age of 65 years were reviewed. Moderate to the substantial intra-observer agreement was achieved with the highest Kapa value in the category of shape (k=0.61-0.77). For TIRADS level, the moderate intra-observer agreement was observed (k=0.42-0.46). Inter-observer agreement for the US category of thyroid nodules was obtained slightly to moderate. Composition (k=0.42 and 0.51) and echogenicity (k=0.45 and 0.46) showed the highest overall agreement and margin showed the lowest overall agreement (k=0.18 and 0.19). In assessing TIRADS level of nodules, a fair agreement was obtained (k=0.23 and 0.29). CONCLUSION: Moderate to substantial intra-observer agreement and slight to moderate inter-observer variation for evaluation of thyroid nodules; shows the need for a computer-aided diagnosis system based on artificial intelligence to assist our physicians in differentiating thyroid nodule characteristics based on explicit image features. An additional training course based on ACR-TIRADS for physicians can be another useful recommendation.

RESUMEN

BACKGROUND: In recent years, several trials investigated the role of anti-inflammatory agents in reducing cardiovascular events. Trehalose is a natural disaccharide able to reduce inflammation by enhancing macrophage autophagic activity. This action has been demonstrated to attenuate atherosclerotic plaque development in various pro-atherogenic animal models. However, at present, no data about the efficacy of this compound in human subjects have been published. METHODS: We performed a randomized, double-blind trial involving 15 patients with history of myocardial infarction and evidence of systemic inflammation (defined as C-reactive protein > 2 mg/L). The patients were randomly assigned, in 2:1 ratio, to receive either intravenous trehalose (15 g once weekly) or placebo for 12 weeks. The primary efficacy end-point was the change in arterial wall inflammation, assessed by quantifying 18F-FDG PET/CT uptake in carotid arteries and ascending aorta. RESULTS: The MDS TBR change of the index vessel at 3-month follow-up was not significant in treatment and placebo groups. Furthermore, we could not demonstrate any significant difference between the trehalose group and control group in changes of cIMT from baseline to 3 months in the overall population. No significant changes in echocardiographic measurement were noted after trehalose treatment. Except for the change in urea level in placebo group (31.00 ± 6.59 vs. 25.60 ± 6.402 P = 0.038) no other changes were detected after treatment. Also, there was a significant difference between changes in alanine aminotransferase (ALT) trehalose and placebo groups. CONCLUSION: This was the first study that specifically assessed the effects of intravenous trehalose on atherogenesis in human subjects. Trehalose treatment was characterized by an optimal safety profile, but no significant reduction in arterial wall inflammation could be observed. This might be a consequence of the small sample size of this trial. Larger studies are needed to better assess the efficacy of this compound in this clinical context.

RESUMEN

The present study aimed to evaluate the sensitivity and specificity of clinical tests and ultrasonography in detecting ankle ligament injuries. In this cross-sectional study, 105 patients with a history of ankle sprain were included. Ankle ligaments, including syndesmosis of ankle, as well as deltoid, calcaneofibular, anterior talofibular, and posterior talofibular ligaments were evaluated by clinical tests, ultrasonography, and magnetic resonance imaging. The sensitivity and specificity of ultrasound and clinical tests were assessed in normal, sprain, partial tear, and complete tear groups. The inter-observer reliability (Cohen's Kappa score) of the evaluated techniques with magnetic resonance imaging was assessed. Anterior drawer test showed a sensitivity and specificity of 81 and 80% in the detection of anterior talofibular ligament injuries, respectively. Ultrasonography showed 100% sensitivity and specificity in distinguishing normal anterior talofibular ligament from the torn or sprained ligament with a kappa value of 1. The sensitivity of ultrasonography in detecting normal calcaneofibular ligament and deltoid ligament was 93% and 90%, respectively. Ultrasonography was highly specific in detecting calcaneofibular ligament tear but it was not sensitive in this regard. Ultrasonography was proved reliable in determining the normal anterior talofibular ligament and calcaneofibular ligament from the torn or sprained ligament. Ultrasonography is an effective complementary tool for primary evaluation of ankle injuries, which leads to early diagnosis and efficient quality of care. Clinical tests are not reliable to rule out the ankle ligaments injury and the results should be interpreted with caution.

RESUMEN

INTRODUCTION: The management of thyroid nodules has been proposed based on US features and information obtained from Fine-Needle Aspiration Cytology (FNAC). In this study, we checked the diagnostic value of ultrasound in comparison with FNAC in probably benign nodules of thyroid. MATERIALS AND METHODS: Patients with thyroid nodules referred to the Radiology department from 2015 to 2020, were classified into five types based on the American College of Radiology/thyroid imaging reporting and data system (TI-RADS) standards. The patients with TI-RADS III-V were examined by FNA biopsy. Subsequently, the collected data of 535 patients having thyroid nodules with TI-RADS III were statistically analyzed. RESULTS: The mean age of the patients was estimated at 46.57. The analysis of TI-RADS III cases examined by the FNA biopsy revealed that 99.1% of the cases were diagnosed with benign lesions. The mean size of benign and malignant nodules was 27mm and 41mm, respectively. There was no significant correlation between the size of the nodules or patients age, and thyroid malignancy (P-values > 0.05). CONCLUSION: There was a very low chance of malignancy (0.9%) in thyroid nodules with thyroid imaging classification of TI-RADS III. Furthermore, no meaningful correlation was observed between the size of the nodules and their malignancy. Therefore, the use of FNAC, based on the current guidelines, on thyroids for nodules larger than 2.5 cm might need to be revised.

CASE PRESENTATION: The case was a 20-year-old woman who was referred to with pain and massive vulvar edema by passing 7 days from her labor. The laboratory tests showed leukocytosis, lymphopenia, and elevated C-reactive protein levels. The high-resolution computed tomography was in favor of Covid-19 changes. Finally, she died because of respiratory distress, ON the 8th day postpartum.
