A 21-year-old Pregnant Trauma Patient with Asymptomatic Fat Embolism; a Case Report

Introduction: Fat embolism syndrome (FES) is most often associated with orthopedic trauma that typically presents 24–72 hours after the trauma with a classic triad. Only few cases of fat embolism due to lower extremity venous system had been reported. Case presentation: The current case report presents a pregnant woman who was referred to our emergency department with bilateral femoral open fracture. After detecting fetal demise by abdominopelvic ultrasound, an area of fat density in right external iliac vein was detected in abdominopelvic contrast enhanced computed tomography (CT) scan which was considered as the probable diagnosis of fat embolism. While the patient did not show signs and symptoms of FES, the fat embolism was confirmed in further evaluations. Conclusion: In summary, although detection of fat embolus in CT scan in the emergency department is very rare, evaluation of lower extremity venous system in a posttraumatic patient seems to be crucial because early diagnosis of fat embolism can help the clinicians to prevent FES

MRI Findings in Children with the First Unprovoked Seizure Presenting to the Emergency Department; Does Developmental Delay Suggest the Importance of Brain MRI Evaluation?

Introduction: The first unprovoked seizure (FUS) in children is a convulsive seizure with an unknown cause, which may be due to an underlying neurological disease or a manifestation of epilepsy. Objective: The aim of this study was to evaluate the findings of brain magnetic resonance imaging (MRI) in pediatric patients with FUS, presenting to the emergency department (ED). Methods: In this cross-sectional study, all children with FUS (age: >1month and<14 years), who were referred to the ED of Qaem Hospital, Mashhad, Iran from 2016 to 2019, were investigated. Medical records, brain MRI findings, electroencephalography (EEG) results, and developmental status of children were reviewed retrospectively. Results: The brain MRI findings of 56 children with FUS were reviewed. The mean age of children was 3.92±6.05 years, and the sex distribution was equal. Seventeen (30.4%) patients had abnormal EEG findings, while 13 (23.2%) patients’ had non-specific EEG findings. Neurological examination of 4 (7.1%) children was abnormal. Overall, 6 (10.7%) patients had non-specific abnormal brain MRI findings for seizure, while 3 (5.4%) patients had specific abnormal findings. A significant relationship was observed between the developmental status of children and abnormal MRI findings (P=0.04). However, MRI findings had no significant relationship with EEG or neurological findings (P>0.05). Conclusion: It may be useful to perform brain MRI for children with FUS presenting to ED, especially those who are suspected of developmental disorders

Is prior use of renin-angiotensin system (RAS) inhibitors associated with more favourable outcome in COVID-19 hospitalized patients?

Objective: We aimed to investigate the extent of pulmonary involvement and adverse outcomes in patients receiving angiotensin-converting enzyme inhibitor (ACEI)/ angiotensin II receptor blocker (ARB) versus who did not, in hospitalized coronavirus infectious disease 2019 (COVID-19) patients. Methods: All COVID-19 patients with a positive polymerase chain reaction (PCR) test, who were admitted to our tertiary referral hospitals in Tehran, Iran between January 2021 and May 2021, and had an on-admission chest computed tomography (CT) scan, were included. The patients were divided into two groups (receiving ACEI/ARB and who did not) for further analysis. The outcomes of interest in our study were the extent of pulmonary involvement, intensive care unit (ICU) admission, and death. Results: A total of 893 participants (mean age of 58.6±15.4 years; female, 522 (58.4%)) were enrolled. Among them, 368 (41.2%) participants had hypertension, and use of ACEI/ARB was reported in 183 (20.5%) participants. Of all, 409 (45.8%) participants required ICU admission, and 259 (29%) participants succumbed to death. We found that participants who received ACEI/ARB were less likely to progress critical disease and experienced significantly lower ICU admission (P=0.022) and death (P<0.001). On multivariable analysis adjusting for age, sex, and comorbidities, this relationship remained statistically significant for death [OR: 0.23 (0.14-0.38); P<0.001] and ICU admission [OR: 0.49 (0.32-0.73); P=0.001]. Conclusion: Our findings showed that COVID-19 patients who receiving ACEI/ARB prior to hospitalization vs. those who did not, had more favorable outcomes

Correlation of clinical, laboratory, and short‐term outcomes of immunocompromised and immunocompetent COVID‐19 patients with semi‐quantitative chest CT score findings: A case‐control study

Abstract Background As the effects of immunosuppression are not still clear on COVID‐19 patients, we conducted this study to identify clinical and laboratory findings associated with pulmonary involvement in both immunocompromised and immunocompetent patients. Methods A case‐control of 107 immunocompromised and 107 immunocompetent COVID‐19 patients matched for age and sex with either positive RT‐PCR or clinical‐radiological findings suggestive of COVID‐19 enrolled in the study. Their initial clinical features, laboratory findings, chest CT scans, and short‐term outcomes (hospitalization time and intensive care unit [ICU] admission) were recorded. In addition, pulmonary involvement was assessed with the semi‐quantitative scoring system (0−25). Results Pulmonary involvement was significantly lower in immunocompromised patients in contrast to immunocompetent patients, especially in RLL (p = 0.001), LUL (p = 0.023), and both central and peripheral (p = 0.002), and peribronchovascular (p = 0.004) sites of lungs. Patchy (p < 0.001), wedged (p = 0.002), confluent (p = 0.002) lesions, and ground glass with consolidation pattern (p < 0.001) were significantly higher among immunocompetent patients. Initial signs and symptoms of immunocompromised patients including dyspnea (p = 0.008) and hemoptysis (p = 0.036), respiratory rate of over 25 (p < 0.001), and spo2 of below 93% (p = 0.01) were associated with higher pulmonary involvement. Total chest CT score was also associated with longer hospitalization (p = 0.016) and ICU admission (p = 0.04) among immunocompromised patients. Conclusions Pulmonary involvement score was not significantly different among immunocompromised and immunocompetent patients. Initial clinical findings (dyspnea, hemoptysis, higher RR, and lower Spo2) of immunocompromised patients could better predict pulmonary involvement than laboratory findings

A technical review of percutaneous sclerotherapy with bleomycin for giant hepatic venous malformation

Abstract Background Hepatic venous malformation (HVM), traditionally called liver haemangioma, is considered the most common benign hepatic lesion. Treatment might be indicated in large and symptomatic HVMs. We aim to describe stepwise technical aspects of trans-hepatic percutaneous sclerotherapy of hepatic venous malformation (HVM). Main text Patients with symptomatic HVM larger than 5 cm are selected after discussion in hepatobiliary multidisciplinary team. After prophylactic antibiotic and corticosteroid administration, local anaesthesia and conscious sedation are applied. A 22-gauge spinal or Chiba needle is used to obtain percutaneous access to the HVM through normal liver parenchyma under ultrasound guidance. To ensure proper needle placement and to prevent accidental delivery of sclerosant into unintended areas, about 5–10 mL iodine contrast is injected under fluoroscopy. Then, 45–60 IU bleomycin is mixed with 10 mL distilled water and 10 mL lipiodol and is slowly injected under fluoroscopy over a period of 20–30 s. After the needle is removed, manual pressure is applied over the puncture site for a period of 5 min followed by placement of a sandbag. Patients are monitored for 6–8 h post-procedure. Conclusion In this technical review, we described our institutional technique of percutaneous sclerotherapy, which could be regarded as an alternative to TAE in the management of HVM

Liver hydatidosis disease with portal vein invasion: Report of a rare case and review of literature

Hydatid disease is a zoonosis caused by Echinococcus granulosus. Humans are aberrant intermediate hosts and following the infection, the parasite may infest any organ of the body, with the liver and lungs being the most involved organs. Portal vein involvement by hydatid cyst disease is extremely rare with only seven cases published to our knowledge. We present a 62-year-old Persian male with an incidental liver cyst. His laboratory tests were in normal ranges. The ultrasonography (US), computed tomography (CT) and magnetic resonance imaging (MRI) findings show hydatid disease of the liver with distal portal vein involvement and collateral venous formations. The patient is being followed and has not gone under surgery yet. It possesses a propensity to invade multiple organ systems, notably the liver and lungs. Hydatid disease is imposing a significant burden on healthcare systems specifically in developing countries. Manifestations of the disease are often non-specific, while a subset of the infected population remains asymptomatic. Portal vein invasion and obstruction is a rare complication, and it is important to distinguish it from vein thrombosis, as the management of these entities requires different approaches
