Screening chest wall ultrasound in the mastectomy patient

BackgroundWhile there are clear guidelines regarding chest wall ultrasound in the symptomatic patient, there is conflicting evidence regarding the use of ultrasound in the screening of women post-mastectomy. ObjectiveTo assess the utility of screening chest wall ultrasound after mastectomy and to assess features of detected malignancies. MethodsThis IRB approved, retrospective study evaluates screening US examinations of the chest wall after mastectomy. Asymptomatic women presenting for screening chest wall ultrasound from January 2016 through May 2017 were included. Cases of known active malignancy were excluded. All patients had at least one year of clinical or imaging follow-up. 43 exams (8.5 %) were performed with a history of contralateral malignancy, 465 exams (91.3 %) were performed with a history of ipsilateral malignancy, and one exam (0.2 %) was performed in a patient with bilateral prophylactic mastectomy. ResultsDuring the 17-month period, there were 509 screening US in 389 mastectomy patients. 504 (99.0 %) exams were negative/benign. Five exams (1.0 %) were considered suspicious, with recommendation for biopsy, which was performed. Out of 509 exams, 3 (0.6 %) yielded benign results, while 2 (0.39 %) revealed recurrent malignancy, with a 95 % confidence interval (exact binomial) of 0.05 % to 1.41 % for screening ultrasound. Both patients who recurred had previously recurred, and both had initial cancer of lobular histology. ConclusionOf 509 chest wall screening US exams performed in mastectomy, 2 malignancies were detected, and each patient had history of invasive lobular carcinoma and at least one prior recurrence prior to this study, suggesting benefit of screening ultrasound in these populations.

Ultrasonographic examination of acute soft tissue lesions in the elbow has good inter-rater reliability and acceptable agreement with magnetic resonance imaging

BackgroundUltrasound (US) has been suggested a valuable complement to clinical and radiological examinations in elbow trauma. Magnetic resonance imaging (MRI) has been the method of choice, despite fair to moderate interrater reliability (IRR). US has potential advantages but is assessor dependent and IRR scarcely examined. The primary aim of the present study was to investigate IRR for US and secondarily inter-observer agreement (IOA) between US and MRI in the acute phase after elbow trauma. Acute phase was defined as 2 weeks and, if applicable, the following weekend. The hypothesis was that US reliability would be at least substantial for complete muscle or ligament lesions. Methods116 patients (50 men, median age 47 [range 19-87] years) suffering an elbow trauma with dislocation and/or fracture were included. Exclusion criteria were prior injury to the same elbow, and US and/or MRI not possible within 16 days. During US the condition of muscle origins at the epicondyles and collateral and annular ligament complexes was recorded in a pre-designed protocol, with the alternatives intact, partially or completely torn. 72 patients had a second US examination the same day by an independent upper extremity surgeon. 58 of the 116 patients underwent an MRI before or after the US, evaluated by 2 radiologists using the same protocol. IOA and IRR between assessors and modalities were analyzed with kappa statistics and interpreted according to Landis and Koch. Perfect agreement (PA) was reported in percent. ResultsUS examination within 2 weeks was feasible with tolerable discomfort. Defining muscle origins and ligaments as intact or completely torn the US IRR ranged from substantial to near perfect (kappa 0,63-1; PA 93-100%). Intact tissues vs tear (partial and complete tear combined) or intact vs partial vs complete tear resulted in kappa values from moderate to substantial and PA 74%-96% with lowest reliability for the muscle origins. The IOA between MRI and US ranged from fair to near perfect for no tear vs complete tear (kappa 0,25-1; PA 65-100%). Agreement between no tear and tear (partial and complete together) ranged from fair to substantial (0,25-0,66; PA 63-89%) and no tear vs partial or complete tear ranged from fair to moderate (0,25-0,53; PA 50-79%). ConclusionUS in the acute setting is suitable and reliable for diagnosis of ligament injuries in the elbow and is in addition fast, cheap and easily accessible. The agreement with MRI seems to vary with the structure assessed and severity of the lesions, ranging from fair to near perfect.

Subclinical Atherosclerosis in a Gout Cohort: Prevalence and Associations.

The current observational, prospective study enrolled 65 patients with gout, diagnosed according to 2015 ACR/EULAR criteria [17], evaluated in Rheumatology Clinic, Emergency County Hospital Craiova, and 40 healthy subjects. This research aimed to determine the presence of subclinical carotid atherosclerosis, revealed by an increased intima media thickness and carotid plaques in gout patients, by US examination. Secondary, we aimed to search for the possible correlations displayed between the presence of subclinical carotid atherosclerosis and several disease variables. CCAIMT over 0.9mm was identified for 19 patients (29.23%), percentage statistically significant different compared to controls (7; 17.5%), p=0,0428. For 23 patients (35.38%) carotid plaques were present at US examination, more prevalent compared to controls (19; 29.23%), p=0.002. Using multivariate logistic regression, we pointed out that SUA (OR 2,103; p=0.0002), age (OR=1,051; p<0.001), disease duration (OR=1.740; p=0.0039) and LDLc (OR=1,003; p=0.0029) were independently associated to an increased IMT in patients with gout, similar results being obtained for carotid plaques. MSKUS was performed for all patients, with important results. The presence of deposits associated with an increased risk of a thick IMT; similar results were obtained for double contour sign, aggregates and tophi. A statistically significant risk was noticed for the presence of deposits (p=0.002). Regarding the presence of carotid atheroma plaques, a higher risk was associated to deposits identification, double contour sign, aggregates, tophi and PD signal. Our results sustain that carotid ultrasound is an easily accessible imagistic method that offers important predictors of atherosclerotic status.

Metabolic Syndrome in Psoriasis Patients-an Observational Study.

Our observational study included on 54 patients with PsO, evaluated into the Dermatology Department of the Emergency County Hospital Craiova, Romania, between August 2023 and January 2024, and 40 controls. Our research proposed determining the prevalence of MetS in a cohort of PsO patients, and its relationship to subclinical atherosclerosis, evaluated by carotid ultrasound. Metabolic syndrome (MetS) was established according to National Cholesterol Education Program (NCP) Adult Treatment Panel (ATP) III criteria for MetS for 35 of the patients (64.81%) vs. 11 of the control group (27.5%), p=0.0003. An overview of each component of MetS depending on the diagnostic criteria for MetS showed that waist and total cholesterol exerted significant differences. Carotid ultrasound evaluation revealed an increased ITM, of over 0.9mm, for 19 (35.18%) or PsO patients, significantly increased compared to controls, as well as the presence of carotid plaques in significantly different percentages (37.03% PsO vs. 17.5% controls, p=0.001). We also noted that for patients with MetS, US examination displayed increased results for IMT compared to those without MetS. The prevalence of carotid atheroma plaque was augmented in patients with MetS and PsO. In our PsO group IMT exerted a positive inter-relation with: age, MetS, blood glucose, disease duration, and PASI. Important to note is that after multiple linear regression analysis, age and MetS were independent indicators of IMT (p=0.02 for age and p=0.001 for MetS). Our findings sustain a firm relationship between MetS and psoriasis and the major consequence of this observation is the inherent risk of cardiovascular events.

Performance of Generative Artificial Intelligence in Dental Licensing Examinations

Generative artificial intelligence (GenAI), including large language models (LLMs), has vast potential applications in health care and education. However, it is unclear how proficient LLMs are in interpreting written input and providing accurate answers in dentistry. This study aims to investigate the accuracy of GenAI in answering questions from dental licensing examinations. A total of 1461 multiple-choice questions from question books for the US and the UK dental licensing examinations were input into 2 versions of ChatGPT 3.5 and 4.0. The passing rates of the US and UK dental examinations were 75.0% and 50.0%, respectively. The performance of the 2 versions of GenAI in individual examinations and dental subjects was analysed and compared. ChatGPT 3.5 correctly answered 68.3% (n = 509) and 43.3% (n = 296) of questions from the US and UK dental licensing examinations, respectively. The scores for ChatGPT 4.0 were 80.7% (n = 601) and 62.7% (n = 429), respectively. ChatGPT 4.0 passed both written dental licensing examinations, whilst ChatGPT 3.5 failed. ChatGPT 4.0 answered 327 more questions correctly and 102 incorrectly compared to ChatGPT 3.5 when comparing the 2 versions. The newer version of GenAI has shown good proficiency in answering multiple-choice questions from dental licensing examinations. Whilst the more recent version of GenAI generally performed better, this observation may not hold true in all scenarios, and further improvements are necessary. The use of GenAI in dentistry will have significant implications for dentist-patient communication and the training of dental professionals.

The added value of color parameter imaging for the evaluation of focal liver lesions with "homogenous hyperenhancement and no wash out" on contrast enhanced ultrasound.

The purpose of this study was to investigate the added value of color parameter imaging (CPI) in the differential diagnosis of focal liver lesions (FLLs) with "homogeneous hyperenhancement but not wash out" on contrast-enhanced ultrasound (CEUS). A total of 101 patients with 108 FLLs were enrolled in this study. All the FLLs received US and CEUS examinations. The stored CEUS clips of target lesions were postprocessed with CPI analysis by radiologists. The receiver operator characteristic (ROC) curve was used to evaluate the added value of CPI. The McNamara test was used to compare the diagnostic sensitivity, specificity, and accuracy between CEUS and CPI patterns. Univariate and multivariate logistic regression analyses were used to develop a CPI nomogram. The C index and calibration curve were used to evaluate the predictive ability of the nomogram. The intraclass correlation coefficient was used to test the reproducibility and reliability of CPI. Decision curve analysis (DCA) was used to evaluate the added value of applying CPI. The following CPI features were more frequently observed in malignant FLLs: eccentric perfusion (malignant: 70.0% vs. benign: 29.2%, p < 0.001), feeding artery (51.7% vs. 4.2%, p < 0.001), mosaic (63.3% vs. 6.3%, p < 0.001), red ingredients >1/3 (90.0% vs. 14.6%, p < 0.001). In addition, centripetal (43.8% vs. 18.3%, p = 0.004), peripheral nodular (54.2% vs. 1.7%, p < 0.001), subcapsular vessel (12.5% vs. 0.0%, p = 0.004), spoke-wheel vessels (25.0% vs. 5.0%, p = 0.003), branched vessels (22.9% vs. 5.0%, p = 0.006), blue and pink ingredients >2/3 (85.4% vs. 10.0%, p < 0.001) were more observed in benign FLLs. A nomogram incorporating peripheral nodular, spoke-wheel vessels, and red ingredients >1/3 was constructed. The model had satisfactory discrimination (AUC = 0.937), and the optimal diagnostic threshold value was 0.740 (0.983, 0.850). By the DCA, the model offered a net benefit over the treat-all-patients scheme or the treat-none scheme at a threshold probability 5%-93%. Using CPI can detect and render subtle information of the main features of FLLs on CEUS; it is conducive to the radiologist for imaging interpretation, and a combining read of the CEUS and CPI of the FLLs with features of "homogenous hyperenhancement and no washout" can improve significantly the diagnostic performance of CEUS for FLLs.

Value of high frame rate contrast enhanced ultrasound in gallbladder wall thickening in non-acute setting

BackgroundUltrasound (US) has been widely used in screening and differential diagnosis of gallbladder wall thickening (GWT). However, the sensitivity and specificity for diagnosing wall-thickening type gallbladder cancer are limited, leading to delayed treatment or overtreatment. We aim to explore the value of high frame rate contrast enhanced ultrasound (H-CEUS) in distinguishing wall-thickening type gallbladder cancer (malignant) from GWT mimicking malignancy (benign).MethodsThis retrospective study enrolled consecutive patients with non-acute GWT who underwent US and H-CEUS examination before cholecystectomy. Clinical information, US image and H-CEUS image characteristics between malignant and benign GWT were compared. The independent risk factors for malignant GWT on H-CEUS images were selected by multivariate logistic regression analysis. The diagnostic performance of H-CEUS in determining malignant GWT was compared with that of the gallbladder reporting and data system (GB-RADS) score.ResultsForty-six patients included 30 benign GWTs and 16 malignant GWTs. Only mural layering and interface with liver on US images were significantly different between malignant and benign GWT (P < 0.05). Differences in enhancement direction, vascular morphology, serous layer continuity, wash-out time and mural layering in the venous phase of GWT on H-CEUS images were significant between malignant and benign GWT (P < 0.05). The sensitivity, specificity and accuracy of H-CEUS based on enhancement direction, vascular morphology and wash-out time in the diagnosis of malignant GWT were 93.75%, 90.00%, and 91.30%, respectively. However, the sensitivity, specificity and accuracy of the GB-RADS score were only 68.75%, 73.33% and 71.74%, respectively. The area under ROC curve (AUC) of H-CEUS was significantly higher than that of the GB-RADS score (AUC = 0.965 vs. 0.756).ConclusionsH-CEUS can accurately detect enhancement direction, vascular morphology and wash-out time of GWT, with a higher diagnostic performance than the GB-RADS score in determining wall-thickening type gallbladder cancer. This study provides a novel imaging means with high accuracy for the diagnosis of wall-thickening type gallbladder cancer, thus may be better avoiding delayed treatment or overtreatment.

Assessing Adherence to US LI-RADS Follow-up Recommendations in Vulnerable Patients Undergoing Hepatocellular Carcinoma Surveillance.

Purpose To assess adherence to the US Liver Imaging Reporting and Data System (LI-RADS) recommendations for hepatocellular carcinoma (HCC) surveillance and associated patient-level factors in a vulnerable, diverse patient sample. Materials and Methods The radiology report database was queried retrospectively for patients who underwent US LI-RADS-based surveillance examinations at a single institution between June 1, 2020, and February 28, 2021. Initial US and follow-up liver imaging were included. Sociodemographic and clinical data were captured from electronic medical records. Adherence to radiologist recommendation was defined as imaging (US, CT, or MRI) follow-up in 5-7 months for US-1, imaging follow-up in 3-6 months for US-2, and CT or MRI follow-up in 2 months for US-3. Descriptive analysis and multivariable modeling that adjusted for age, sex, race, and time since COVID-19 pandemic onset were performed. Results Among 936 patients, the mean age was 59.1 years; 531 patients (56.7%) were male and 544 (58.1%) were Asian or Pacific Islander, 91 (9.7%) were Black, 129 (13.8%) were Hispanic, 147 (15.7%) were White, and 25 (2.7%) self-reported as other race. The overall adherence rate was 38.8% (95% CI: 35.7, 41.9). The most common liver disease etiology was hepatitis B (60.6% [657 of 936 patients]); 19.7% of patients (183 of 936) had current or past substance use disorder, and 44.8% (416 of 936) smoked. At adjusted multivariable analysis, older age (odds ratio [OR], 1.20; P = .02), male sex (OR, 1.62; P = .003), hepatology clinic attendance (OR, 3.81; P < .001), and recent prior US examination (OR, 2.44; P < .001) were associated with full adherence, while current smoking (OR, 0.39; P < .001) was negatively associated. Conclusion Adherence to HCC imaging surveillance was suboptimal, despite US LI-RADS implementation.

Non-Invasive Quantitative Approximation of Intracranial Pressure in Pediatric Idiopathic Intracranial Hypertension Based on Point-of-Care Ultrasound of the Optic Nerve Sheath Diameter.

To investigate whether ultrasound-based optic nerve sheath diameter (US-ONSD) is a reliable measure to follow up children with idiopathic intracranial hypertension (IIH). In addition, to analyze the inter- and intra-individual relationships between US-ONSD and intracranial pressure (ICP), and to investigate whether an individualized mathematical regression equation obtained from two paired US-ONSD/ICP values can be used to approximate ICP from US-ONSD values. 159 US examinations and 53 invasive ICP measures via lumbar puncture (LP) were performed in 28 children with IIH. US-ONSD was measured using a 12 Mhz linear transducer and compared to ICP values. In 15 children, a minimum of 2 paired US-ONSD/ICP determinations were performed, and repeated-measures correlation (rmcorr) and intra-individual correlations were analyzed. The cohort correlation between US-ONSD and ICP was moderate (r = 0.504, p < 0.01). Rmcorr (r = 0.91, p < 0.01) and intra-individual correlations (r = 0.956-1) of US-ONSD and ICP were excellent. A mathematical regression equation can be calculated from two paired US-ONSD/ICP values and applied to the individual patient to approximate ICP from US-ONSD. Related to excellent intra-individual correlations between US-ONSD and ICP, an individualized regression formula, created from two pairs of US-ONSD/ICP values, may be used to directly approximate ICP based on US-ONSD values. Hence, US-ONSD may become a non-invasive and reliable measure to control treatment efficacy in pediatric IIH.

Ultrasonography Enthesitis and Synovitis Screening in Psoriatic Patients: A Case Control Study.

The clinical screening of enthesitis and synovitis in patients with psoriasis lacks specificity and sensitivity during the preclinical phase. to assess US subclinical synovitis and enthesitis in psoriatic patients compared with healthy controls. A cross-sectional study on 40 psoriatic patients and 40 healthy sex- and age-matched controls. US examination of 18 joints was performed along with 22 entheseal sites on the upper and lower limbs. US subscores were established according to the US abnormalities: inflammatory score (tendon thickening, hypoechogenicity, bursitis, Doppler signal), damage score (calcification, enthesophytes, bone erosion) and total score (the sum of inflammatory and damage scores). US synovitis were more frequent in psoriatic patients (0.68%) than in controls (0.29%), but the difference was not significant. Patients with psoriasis had more US enthesitis (92,5%) compared to controls (40%)(p<0.001). The total number of enthesitis was higher in the psoriatic group (20.90%) compared to controls (4,78%)(p<0.001). There were more US abnormalities in the psoriatic group compared to controls for calcaneal tendon enthesis(p<0.001), distal patellar tendon enthesis(p<0.001) and deep flexor tendons of the finger enthesis(p<0.001). Compared to controls, psoriatic patients had a significantly higher inflammatory score (Mean±SD) (2.85±3.34 versus 0.58±1.17), damage score (3±2.57 versus 0.60±1.41), and total score (5.85±5.20 versus 1.18±2.07) (p < 0.001 each). Patients with scalp psoriasis had more US enthesitis (p=0.020). Our results indicate that US enthesitis and synovitis are more frequent in patients with psoriasis. Prospective studies with larger sample size are needed to define the contribution of US in predicting the clinical onset of PsA.

Diagnosis of calcium pyrophosphate crystal deposition disease by ultrasonography: how many and which sites should be scanned?

To develop the optimal US scanning protocol for the diagnosis of calcium pyrophosphate crystal deposition (CPPD) disease. In this cross-sectional study, consecutive patients with a crystal-proven diagnosis of CPPD disease, and age-, sex-matched disease controls with a negative synovial fluid analysis were prospectively enrolled in two Italian Institutions. Four rheumatologists, blinded to patients' clinical details, performed US examinations using a standardized scanning protocol including 20 joints (shoulders, elbows, wrists, metacarpophalangeal joints from second to fifth fingers, hips, knees, ankles). CPPD was identified as presence/absence, according to the OMERACT definitions. Reduced US scanning protocols were developed by selecting the most informative joints to be imaged by US using the LASSO technique. Patients were randomly divided into training and validation sets. Their diagnostic accuracy was tested comparing the area under the receiver operating characteristic curves. The number of participants enrolled was 204: 102 with CPPD disease and 102 disease controls [age, mean (s.d.): 71.3 (12.0) vs 71.1 (13.5) years; female: 62.8% vs 57.8%]. The median number of joints with US evidence of CPPD was 5 [interquartile range (IQR): 4-7] and 0 (IQR: 0-1) in patients with CPPD disease and controls, respectively (P < 0.01). The detection of CPPD in ≥2 joints using a reduced scanning protocol (bilateral assessment of knees, wrists and hips) showed a sensitivity of 96.7% (95% CI: 82.8, 99.9) and a specificity of 100 (95% CI: 88.8, 100.0) for the diagnosis of CPPD disease and had good feasibility [mean (s.d.): 12.5 (5.3) min]. Bilateral US assessment of knees, wrists and hips had excellent accuracy and good feasibility for the diagnosis of CPPD disease.

Use of a controlled attenuation parameter for the diagnosis of non-alcoholic fatty liver disease

To evaluate the efficacy of vibration-controlled transient elastography (VCTE) with a controlled attenuation parameter (CAP) in a population of patients with non-alcoholic fatty liver disease (NAFLD)and to compare to US and different non-invasive indices. Single center NAFLD patients' database of 2021-2023 years was retrospectively analysed. Data of VCTE evaluation with CAP (FibroScan 530® and FibroScan 630 Expert®) as well as liver US examination results and values of HSI, FLI, BAAT and NAFLD-LFS were extracted. AUROCs for all methods used were constructed and sensitivity and specificity analysis was performed. The data of 1081 patients were available for analysis (385 with steatosis, 274 with NASH, 422 without NAFLD as a control). Ultrasound examination in the diagnosis of liver steatosis compared to VCTE with CAP showed sensitivity and specificity of 94.6 and 63.7%, respectively. Diagnosis of liver steatosis using indices and scales showed sensitivity and specificity of HSI: 97.9 and 60.1% (AUROC 0.90), FLI: 92.5 and 85.3% (AUROC 0.93), BAAT: 76.6 and 73.5% (AUROC 0.82), NAFLD-LFS: 56.7 and 81.8% (AUROC 0.85). The sensitivity of the US of the liver was consistent with previous studies, but the specificity was low. The HSI index had the best indicators of sensitivity and specificity in relation to the diagnosis of liver steatosis. Combination of liver US and HSI can be used in screening of liver steatosis, however, for the complete diagnosis better tools which can simultaneously evaluate liver steatosis and fibrosis should be used.

Ultrasound Diagnosis and Behaviors in Cases with Encapsulated and Unrestricted Liquid Collections into Body Cavities

Purpose: We present our experience in the diagnosis, follow-up and planning therapy of thoracic, abdominal and retroperitoneal liquid collections in different emergency patients using conventional and interventional ultrasound. Material and Methods: The right and left oblique and propositioning view was used in 235 patients/159 male and 76 female/ for US examination to identify fluids in the thorax and peritoneal or retroperitoneal space. The examination was performed after the clinical survey with patient’s supine. Positive findings of US were compared with those provided by CT, punctures under US control or surgery. US machine supplied with linear and convex transducers, CT machine, needles and catheters were used. Results: 197 of all 235 US examined patients had fluid collections, confirmed by CT scan, surgery or clinical course. In 156 patients we performed FN diagnostic punctures under US control. There was 155 true-positives, 25 true-negatives, 5 false-positives and 2 false-negative results. Overall this demonstrated that ultrasonography have sensitivity of 98.72%, specificity of 83.33% and accuracy of 96.25 %. The PPV is 96.87% and the NPV – 92.59%. Conclusions: Our experience and literature reports support the opinion that US examination can and should be used as a primary method for diagnosis and follow-up of clinically suspected free and organized fluids in the thorax, abdomen and retroperitoneum.

Prediction of placenta accreta spectrum in patients with placenta previa using a clinical, US and MRI combined model: A retrospective study with external validation

PurposeTo build and validate a predictive model of placental accreta spectrum (PAS) in patients with placenta previa (PP) combining clinical risk factors (CRF) with US and MRI signs. MethodOur retrospective study included patients with PP from two institutions. All patients underwent US and MRI examinations for suspicion of PAS. CRF consisting of maternal age, cesarean section number, smoking and hypertension were retrieved. US and MRI signs suggestive of PAS were evaluated. Logistic regression analysis was performed to identify CRF and/or US and MRI signs associated with PAS considering histology as the reference standard. A nomogram was created using significant CRF and imaging signs at multivariate analysis, and its diagnostic accuracy was measured using the area under the binomial ROC curve (AUC), and the cut-off point was determined by Youden’s J statistic. ResultsA total of 171 patients were enrolled from two institutions. Independent predictors of PAS included in the nomogram were: 1) smoking and number of previous CS among CRF; 2) loss of the retroplacental clear space at US; 3) intraplacental dark bands, focal interruption of the myometrial border and placental bulging at MRI. A PAS-prediction nomogram was built including these parameters and an optimal cut-off of 14.5 points was identified, showing the highest sensitivity (91%) and specificity (88%) with an AUC value of 0.95 (AUC of 0.80 in the external validation cohort). ConclusionA nomogram-based model combining CRF with US and MRI signs might help to predict PAS in PP patients, with MRI contributing more than US as imaging evaluation.

Risk Factors for Nonalcoholic Fatty Liver Disease among Patients Referred to Radiological Departments at Hail Hospitals, KSA

Background: Nonalcoholic fatty liver disease (NAFLD) incidence and prevalence have increased globally. The gravity of this chronic disease comes from its ability to progress to cirrhosis and hepatocellular carcinoma, which are rising rapidly. Genetic, demographic, environmental, and clinical factors are significant in the occurrence of NAFL. This study aimed to assess risk factors that affect the occurrence of NAFLD. Methods and Results: This cross-sectional study was carried out at hospitals in the Hail Region, KSA. It included 160 patients: 76 were considered as control (normal liver), and 84 suffered from fatty liver (according to a US image). Sonography was carried out using a US scanner with curvilinear transducers having a frequency of 3.5MHz. The following data were obtained: age, BMI, clinical history, including long-term medication of more than 3 months (oral antidiabetic medications, hormone replacement therapy for hyperthyroidism, and antihypertensive drug), T2D, viral hepatitis, liver span, lipidemia, metabolic disorders, and weight loss. The prevalence of NAFLD increases significantly among patients taking medications for a long time and T2D patients (P&lt;0.001). Hepatomegaly is one of the most common physical examination findings of NAFLD (P&lt;0.001). Conclusion: A periodic US examination is helpful because it can reveal fatty infiltration of the liver in the early stages to avoid fatal complications, especially for patients with long-term medication or T2D. Other studies with larger sample sizes and different known risk factors are needed to discover all risk factors for the KSA population.

Prevalence of Underreported Nicotine Exposure Among US Nonsmoking Adults: A Comparison of Self-Reported Exposure and Serum Cotinine Levels From NHANES 2013-2020.

Secondhand smoke (SHS) poses a significant health risk. However, individuals who do not smoke may be unaware of their exposure, thereby failing to take protective actions promptly. We assessed the prevalence of underreported nicotine exposure in a nationally representative sample of US nonsmoking adults using data from the US National Health and Examination Survey. Individuals with underreported nicotine exposure were defined as those who reported no exposure to all tobacco products (traditional tobacco, nicotine replacements, and e-cigarettes) or SHS, yet had detectable levels of serum cotinine (>0.015 ng/mL). We fitted logistic regression models to determine sociodemographic and chronic condition factors associated with underreported nicotine exposure. Our analysis included 13 503 adults aged 18 years and older. Between 2013 and 2020, the prevalence of self-reported SHS exposure, serum cotinine-assessed nicotine exposure, and underreported nicotine exposure among US nonsmokers were 22.0%, 51.2%, and 34.6%, respectively. Remarkably, 67.6% with detectable serum cotinine reported no SHS exposure. Males, non-Hispanic blacks, individuals of other races (including Asian Americans, Native Americans, and Pacific Islanders), and those without cardiovascular diseases were more likely to underreport nicotine exposure than their counterparts. The median serum cotinine value was higher in respondents who reported SHS exposure (0.107 ng/mL) than in those who reported no exposure (0.035 ng/mL). We estimate that approximately 56 million US residents had underreported nicotine exposure. Over a third of US nonsmokers underreport their nicotine exposure, underlining the urgent need for comprehensive public awareness campaigns and interventions. Further research into sociodemographic determinants influencing this underreporting is needed. Understanding the extent of underreported nicotine exposure is crucial for developing effective public health strategies and interventions. It is imperative to bolster public consciousness about the risks associated with SHS. Additionally, surveillance tools should also incorporate measures of exposure to outdoor SHS and e-cigarette vapor to enhance the quality of data monitoring. Findings from this study can guide tobacco control initiatives and inform smoke-free air legislation.

Age-specific incidence of joint disease in paediatric patients with haemophilia: A single-centre real-world outcome based on consecutive US examination.

Joint health is one of the most important factors contributing to a healthy life in patients with haemophilia. Recent study revealed that starting early prophylaxis was not enough to prevent joint disease in most paediatric patients with haemophilia. In this study, we aimed to determine the age-specific incidence of acute joint disease during childhood at single haemophilia treatment centre (HTC). The joint health in 48 patients was evaluated based on consecutive US testing for 5 years at annual multidisciplinary comprehensive care. During the study period, 23 patients (47.9%) had no joint disease since the initial examination, whereas 13 patients (27.0%) showed development from negative to positive findings. The incidence of joint disease increased with age: 0% in preschool, 5.3% in elementary school, 14.3% in junior high school and 35% beyond high school age. Among the 13 patients who developed joint disease, two experienced acquired synovitis that resolved during the follow-up period. Statistical analysis revealed that the patients who routinely underwent follow-up by the HTC exhibited a significantly lower incidence of joint disease than did those followed up at other institutions (p<.001). These results indicated that close check-up, including routine joint examination using US as well as frequent assessment of pharmacokinetic profile at the HTC, might play an important role in avoiding joint disease among paediatric patients with haemophilia.

Neu Laxova Syndrome—A Terrifying Disease in Two Siblings With a Novel Variant in PHGDH Gene

Introduction Neu-Laxova Syndrome (NLS) is a rare, autosomal, and recessively inherited disease characterized by severe congenital malformations, leading to prenatal or early postnatal mortality. The hallmark clinical features of this syndrome are severe intrauterine growth restriction, central nervous system abnormalities, restrictive dermopathy, and characteristic facial dysmorphia. There is no cure or treatment for this syndrome and the termination of the pregnancy is the suggested approach. Case description Here, we report a new case of 2 siblings with NLS, diagnosed in utero by ultrasonography and genetic examination. Two variants in heterozygosity in the phosphoglycerate dehydrogenase gene were discovered, including a previously uncharacterized variant (c.487C&gt;T p. [Arg163Trp]). Comments Despite all the advances in prenatal diagnosis, NLS remains undiagnosed in many pregnancies. Early and sequential US examinations should be performed in high-risk pregnant women, to establish an early diagnosis.

The burden of entheseal involvement in systemic lupus erythematosus: a comparative ultrasonograghic study

BackgroundImaging is crucial for identifying and diagnosis of the musculoskeletal (MSK) symptoms, which are one of the most typical manifestations of systemic lupus erythematosus (SLE). For the joints, tendons, and entheseal sites, ultrasonography has shown to be sensitive and accurate for the diagnosis of both inflammation and structural damage.AimThe goal of the current investigation is to determine the prevalence and the distribution of entheseal abnormalities in SLE patients, using musculoskeletal ultrasonography (MSUS) and to assess the relationship between entheseal sonographic changes and the SLE disease activity.Patients and methodsOne hundred sixty-eight subjects were studied (56 SLE patients, 56 psoriatic arthritis (PSA) patients, and 56 normal cases). To compare the frequency and the distribution of entheseal involvement, high-resolution MSUS was conducted to assess the entheseal sites of all patients in accordance with the Madrid Sonographic Enthesitis Index (MASEI).ResultsClinical enthesitis was detected in 39.3% of the SLE patients using the Leeds Enthesitis Index compared to 71% detected via US examination, indicating a high proportion of subclinical enthesitis in our SLE patients. The most frequently affected enthesis was the distal insertion of the patellar tendon at the tibial tuberosity which was detected in 41% of SLE patients. Enthesitis was significantly more frequent in PSA patients (100%) compared to SLE patients (71.4%) (p < 0.05) and more significantly frequent in SLE patients compared to the healthy controls (19.6%). There was a significant correlation between MASI and SLEDAI scores (r = 0.250*, p = 0.048) and the total protein in 24 h (r = 0.289*, p = 0.031). In addition, there was an inverse significant correlation between MASEI and serum albumin (r = − 0.324*, p = 0.015).ConclusionIn SLE patients, enthesitis is frequently clinical and ultrasound-verified. The most impacted enthesis is at the insertion of the quadriceps tendon. Enthesitis presence and the rise in the MASI score can serve as indicators of the severity of the SLE disease.Key Points• The most impacted entheseal site lies at the insertion of the quadriceps tendon.• The presence and the rise in MASEI score can serve as indicators of the severity of the SLE disease.

Validation of the modified Alvarado score on patients attending A&E units with suspected appendicitis

IntroductionThe aim of our prospective study was to confirm validity and diagnostic accuracy of the modified Alvarado score, which was developed at the Department of Surgery, University of Szeged, on patients presenting with symptoms suggestive of acute appendicitis (right lower quadrant complaints) at the A&E department.Patient population, methods138 patients were included in our study between 01.01.2019 and 01.01.2020. For patients attending A&E, the first medic calculated and recorded the modified Alvarado score before surgical consultation. The consulting surgeon decided on further treatment without knowing the score. Validation of the score was based on the pathology report of the removed appendix (whether the operation was warranted, and if the score also supported indication for surgery), if there was readmission or surgery due to worsening symptoms after discharge from A&E. We also examined if there was any connection between the value of the Alvarado score and the severity of inflammation. Our aim was to prove that using modified Alvarado score at the A&E Units helps to reduce patient’s waiting time and avoid unnecessary surgical consultations. Furthermore our study included measuring the diagnostic accuracy of the ultrasound examination (specificity, sensitivity).ResultsBased on the results, patients presenting at A&E had a mean modified Alvarado score of 6.5. Comparing the score to histological results showed that the specificity of the modified Alvarado score was 100%, and its sensitivity was 80.7%. Based on Spearman’s rank correlation (0.796) and ROC analysis (AUC 0.968), the modified Alvarado score has an excellent predictive value in diagnosing acute appendicitis. When comparing the patients’ waiting times with the use of modified Alvarado score and without it we found that there was a significant difference in group also in group under 4 points and in group over 7 points when using modified Alvarado score, so the diagnostic and therapeutic algorithm should be much quicker with the help of the score. We found a correlation between the severity of inflammation based on the Fisher’s exact test. Rank correlation of the same question also showed a significant connection. All patients had an US examination during their diagnostic course, its sensitivity was 82.6%, specificity was 87%. Based on this, we can conclude that the predictive value of the imaging method is good.ConclusionsWe can conclude according to our results that the predictive value of the modified score is excellent, and it can be safely applied by non-surgeons in urgent care in the differential diagnosis of acute appendicitis. The new score incorporates the results of an easily obtainable, ionising radiation free imaging method, the ultrasound, which was not included in previous scores. With the help of the new score, the number of unnecessary surgical referrals and waiting times for patients are reduced, excess examinations will become avoidable.
