Spontaneous intraparenchymal cerebral hemorrhages (SIPH) account for 10–15% of acute strokes. Sorting these patients according to the risk of harboring an underlying vascular etiology may help selecting the patients who would mostly benefit from Multidetector CT Angiography (MDCTA). The aim of this study was to evaluate the accuracy of Non-Contrast brain CT (NCCT) in predicting possible vascular etiologies in patients with SIPH. In this retrospective study, we evaluated the NCCT of 334 patients who presented with SIPH from March 2017 to March 2021 and we looked for vascular etiologies in the CTA which was performed for these patients. We used NCCT criteria to predict the presence of any vascular etiologies in SIPH patients and proposed a scoring system based on these criteria which might predict the risk of vascular ICH (VICH score). Out of 334 evaluated patients, 9.3% had an underlying vascular etiology. Independent predictors of the vascular etiology included: age < 46 years, no history of hypertension and coagulation disorders, lobar hemorrhages, and presence of significant perilesional edema. We used these criteria and NCCT classification to create a practical scoring system to predict the risk of vascular ICH (VICH). In our study, VICH score ≥ 4 had 51.6% sensitivity and 96.4% specificity for predicting a positive MDCTA as the maximum optimal cut-off point. The VICH score seemed to be successful in predicting vascular etiologies in this retrospective cohort of 334 patients. This scoring system can be used to select patients if there are limited resources to perform CT angiography. [ABSTRACT FROM AUTHOR]

Introduction: Health care systems all over the world face numerous challenges as a result of the rapid spread of the COVID-19 virus that has resulted in increased mortality rates. About 40% of ICU-admitted COVID-19 patients were not severely ill at the time of admission. Thus, by using appropriate ICU admission predictors, clinicians can identify potential critical patients early on. It can also result in suitable resource allocation and consideration for these patients. Therefore, the current study was done with the aim of identifying clinical characteristics and laboratory data that could predict ICU admission in cases with COVID-19. Methods: This two-center retrospective observational study was done in Imam Reza and Ghaem Hospitals, Mashhad, Iran. Overall, 334 COVID-19 patients who referred to these hospitals from February to May 2020 were enrolled in this study. The participants were separated into two groups according to ICU admission status. All demographic, clinical, and paraclinical information were extracted from the medical records of the patients. Results: The present study composed of 88 ICU and 246 non-ICU-admitted COVID-19 patients. No significant differences were found in age between the two groups of patients (P=0.154). Multivariate regression analysis revealed that higher levels of CRP (OR=1.01, 95%CI 1.001-1.010, P=0.016), WBC (OR=1.11, 95% CI 1.01-1.22, P=0.03), and HRCT scores (OR=1.08, 95%CI=1.01-1.16, P=0.037) were linked to higher odds of ICU admission. Conclusion: This study suggests that higher levels of CRP, WBC, and LDH, as well as the HRCT score at the time of admission, were potential independent predictors of ICU admission during inpatient treatment in COVID-19 patients.

Background: Chronic pulmonary thromboembolism (CTEPH) is an unusual complication of acute pulmonary embolism (PE), which is now considered to be treatable. In modern multi- detector scanners, a detailed evaluation of pulmonary artery geometry is currently possible. This study aimed to evaluate the changes in pulmonary artery bifurcation angle (PABA) in the follow-up computed tomography angiography (CTA) of patients with acute PE. Methods: In this cross-sectional study, the records of two tertiary-level academic hospitals were gathered from 2012 to 2019. Pulmonary artery (PA) bifurcation angle and diameter were measured. Chi square test, independent samples t test, Mann-Whitney, and Pearson's tests were employed to compare data. To evaluate the cut-off point, we utilized receiver operating characteristic (ROC) curve analysis. The accuracy, sensitivity, and specificity of pulmonary artery bifurcation angle changes were calculated. A P value <0.05 was considered to be significant. Results: Forty-six patients were included in the study. No significant differences were found between patients with and without CTEPH, and PABA in the dimeters of PA trunk, right PA, and left PA in the first CTA images (P values of 0.151, 0.142, 0.891, and 0.483, respectively), while in the secondary CTA, the mean PABA was significantly smaller in patients with CTEPH (P=0.011). In the receiver operating characteristic (ROC) analysis, delta angle revealed an area under the curve of 0.745 and an optimal cutoff of 0, leading to a sensitivity of 64%, specificity of 87%, and accuracy of 76% for diagnosing CTEPH. Conclusion: We showed a significant decrease in PABA in patients developing CTEPH. This parameter can be easily measured in lung CTA. [ABSTRACT FROM AUTHOR]

Background: The normal range of kidney size is a controversial issue among different populations given to its impressibility by multiple factors, therefore, this study aimed to provide valid reference ranges for kidney dimensions in the adult population of Mashhad. Also, we assessed the association of kidney size characteristics with some personal predisposing factors. Methods: This cross-sectional study was conducted on 938 healthy individuals. Ultrasound measurement, physical examination, and laboratory analysis were performed. Demographic, dietary, and anthropometric data were obtained. The variables were categorized into 5 groups each, and data analysis were performed using the following statistical tests: Pearson correlation test, variance analysis, t-test, and chi-square test. A value of p<0.05 was considered statistically significant. Results: Weight had the most association with kidney size followed to a lesser extent by height and age. Even after adjustment for other confounding variables, weight remained as an independent factor, while this effect was resolved for height and age. Also, all values for renal function, body bio-impedance, blood pressure components, and water intake were notably correlated with kidney size. Conclusion: This study determined the normal kidney size in healthy adults. We also declared the normal range of kidney size is a dynamic concept and should be assessed for each individual separately according to their personal determinative factors. [ABSTRACT FROM AUTHOR]

Objective(s): Systemic lupus erythematosus (SLE) is an autoimmune disease with a wide range of clinical manifestations. Cognitive dysfunction is one of the manifestations that could present prior to the emergence of any other neuropsychiatric involvements in SLE. Cognitive dysfunction is a subtle condition occurring with a high frequency. However, there is no data on the correlation of cognitive dysfunction with central nervous system (CNS) imaging findings, in particular single-photon emission computed tomography scan (SPECT) and functional MRI. We decided to perform a systematic review of brain SPECT and fMRI in SLE patients with cognitive dysfunction. Methods: PubMed, Scopus, and Google Scholar databases were searched until April 2017 with the following keywords: "SLE OR systemic lupus erythematous OR lupus" AND "functional MRI OR functional magnetic resonance imaging OR fMRI OR SPECT or SCAN". A total of 1,767articles were found. Two rheumatologists reviewed the articles and finally 14 articles were selected for the final systematic review. Results: The fMRI and SPECT imaging techniques could provide valuable information regarding the SLE patients with cognitive dysfunction at the early stages of the disease. Conclusion: Brain SPECT scan and fMRI are used as functional imaging tools in SLE. Both of these diagnostic modalities are sensitive in reflecting the subtle brain damages in SLE patients with cognitive dysfunction. Brain fMRI and SPECT scan could be significantly beneficial in the diagnosis and initial management of cognitive dysfunction in SLE. Nevertheless, prospective studies could be useful in confirming the application of these diagnostic modalities in the clinical setting. [ABSTRACT FROM AUTHOR]

Background: Systemic sclerosis (SS) is a collagen vascular disease of unknown etiology that is characterized by connective tissue abnormalities. This study aimed to evaluate the extra-pulmonary manifestations of SS on chest high resolution computed tomography (HRCT). Materials and Methods: The medical records of patients with SS who presented to our hospital in a 10-year period were retrospectively reviewed. Forty patients with SS were included in this study. The extra pulmonary manifestations of SS were evaluated in these patients, including esophageal involvement, pulmonary arterial dilatation, pleural abnormalities, pericardial disease and mediastinal lymph node involvement. Results: The most common extra-pulmonary manifestation was esophageal dilatation, which was detected in 70% of the cases followed by pleural involvement. Pulmonary arterial dilatation was seen in 20%, pleural involvement in 40%, pericardial involvement in 40% and mediastinal lymphadenopathy in 30%. The most common pleural abnormality was diffuse pleural thickening and the most common pericardial abnormality was pericardial effusion. There was an association between the severity of lung fibrosis with the incidence of esophageal dilatation and pulmonary arterial hypertension (PAH) in our series. Patients with SS and interstitial lung disease (ILD) who had PAH, had more severe lung fibrosis than those without PAH. Conclusion: Patients with SS may have a variety of extra-pulmonary manifestations, which can be detected using HRCT. Our study evidenced that HRCT was useful for detecting extra-pulmonary findings of SS such as esophageal dysmotility and dilatation, enlargement of main pulmonary artery and PAH, pleuropericardial involvement and mediastinal lymphadenopathy.

Lung metastasis is a rare cause of hemoptysis. Bronchial artery embolization is an effective intervention for treatment of hemoptysis with various underlying etiologies. A 28-year-old man with a known history of malignant melanoma in the neck from 6 years ago and lung metastasis from 1 year ago referred to the Emergency Department of our teaching hospital with the chief complaint of hemoptysis. Chest x-ray and pulmonary CT-scan showed multiple pulmonary nodules with different sizes in both lung parenchyma. The patient's hemoptysis did not resolve completely in spite of appropriate medical treatment. The patient was then referred to the endovascular unit of the vascular department in our hospital and underwent bilateral bronchial artery embolization. With this procedure his symptoms resolved completely and he was discharged after a week. [ABSTRACT FROM AUTHOR]

Descriptive case report of a 42-year old woman with coetaneous vasculitis, and severe abdominal pain, which was led to diagnostic laparotomy. These presentations are probably as a side effect of Methocarbamol injection. This is the first report according to our literature search (PubMed, google scholar, ISI web of knowledge, ProQuest, MD consult, Science Direct, SCOPUS) about Methocarbamol related vasculitis from 1966 since now. Vasculitis is not a known side effect of Methocarbamol. This case indicates, likely the potential for development of vasculitis with this medication. [ABSTRACT FROM AUTHOR]

Purpose: To systematically review the recent alternative medical interventions on renal colic pain and compare their efficiency with conventional treatments. Materials and Methods: This was a systematic review and network meta-analysis (NMA) study, based on the PRISMA guidelines on online databases of PubMed, Scopus, and web of science. We quarried these databases with relevant keywords for clinical trial studies that aimed at reducing renal colic pain in patients refereeing to the ED from after January 2011 to February 2022. Randomized clinical trials that used the Visual Analogue Scale (VAS) for assessment of renal colic pain before and after medical interventions in adult patients were included in this study. NMA was conducted based on the continuous values of the mean difference of the pain after 30 and 60 minutes of the medication administration. Results: Twenty-four studies that were meeting the inclusion criteria were included in our review with 2724 adult participants who were mostly male. Study arms included conventional medications (NSAID, Opioid, paracetamol), ketamine, MgSo4, desmopressin, and lidocaine. Based on the qualitative synthesis, ten studies (41.7%) did not find significant differences between conventional and alternative treatments. Also, there is no agreement on some more recent medications like using ketamine or desmopressin while MgSO4 and lidocaine use are supported by most studies. NMA revealed that desmopressin is significantly having worse pain reduction properties. NMA did not show any difference between ketamine, lidocaine, and MgSo4, versus the conventional treatment. Conclusion: To conclude, lidocaine and MgSo4 might be good alternative treatments for renal colic when conventional treatments are contraindicated or pain is not responding to those. Ketamine might be indicated in patient- based circumstances. Desmopressin may be agreeably avoided in further research or clinics. [ABSTRACT FROM AUTHOR]

Background: Increased subcutaneous fat thickness and depth of target organs in over-obese patients, results in weak signals and inadequate images. Tissue harmonic imaging has been used widely in obese patients and is believed to result in higher quality images. This superiority is not proved in modern machines with improved image quality in conventional mode. Objective: To compare the image quality between conventional and tissue harmonic ultrasound images. Methods: This cross-sectional study was carried out from March 2015 to June 2016. Seventy-six over-obese patients referred to Ghaem Hospital (Mashhad, Iran) for weight-correction surgeries, were enrolled into the study. Conventional and tissue harmonic images of their kidneys were blinded and compared back-to-back by four expert radiologists. Data were analyzed by SPSS version 16, using Cochrane's Q test. Results: All raters reported image quality to be better in tissue harmonic compared to fundamental frequency ultrasound (p=0.000, Cochrane's Q test). Although better image quality in tissue harmonic mode was reported by the four raters, there was weak inter-observer agreement (p=0.081 for right kidney and p=0.21 for left kidney). Conclusion: Advances in ultrasound equipment and the introduction of tissue harmonic imaging can improve the diagnostic performance in over-obese patients and this mode of imaging should be used whenever evaluating over-obese subjects.

Background: Soluble Fas (sFas) is a marker of apoptosis that appears to increase in the serum of systemic lupus erythematosus patients and may have a correlation with disease activity. The exact role of sFas in apoptosis is not clear. The purpose of this study is to assess the correlation between serum levels of soluble Fas (Apo/1-CD95) and the activity of systemic lupus erythematosus. Patients and Methods: Our study was performed on 114 systemic lupus erythematosus patients who were compared with 50 randomly selected sex, age and race-matched healthy controls. Disease activity was defined according to the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI-2K). All physical exams and laboratory parameters were collected to determine the SLEDAI. sFas levels were determined using a commercially available ELISA kit. Results: There was a significant difference between serum levels of sFas in the case and control groups (P=0.001). A significant correlation coefficient existed between the sFas and SLEDAI2K variables (P=0.001, r=0.494). Significant statistical difference was found between serum levels of sFas in the active and inactive phases of disease according to SLEDAI= 9 or≥10, (P=0.002). The sFas levels were 270 - 300 pg/mL for SLEDAI≤9 and 355-502 pg/mL for SLEDAI≥10, with a confidence interval of 95%. Conclusion: This study shows a significant elevation of sFas levels in the sera of systemic lupus erythematosus patients with active disease; therefore it can be used as an appropriate marker for evaluation of disease activity.
