Background: Febrile seizures (FS) are the most common form of convulsion in children with the aged between 6 months to 5 years. Different studies have shown that reduction of zinc leads to the incidence of FS in children. Objectives: This study was conducted with the goal of examination of the zinc level in the patients with FS. Patients and Methods: This case-control study was conducted on 90 children in three equal groups of children with febrile seizures, febrile children without febrile seizures (FS) and healthy children. In order to examine the zinc level blood samples were taken of all subjects and the zinc level of these patients was determined. The data was analyzed using the SPSS-16 statistical software and by descriptive statistical tests and ANOVA.
Introduction: Ovarian vein thrombosis usually presents within 7 days after delivery. Clinically, patients appear very ill, and their accompanying symptoms include back pain, fever, and abdominal pain. In these patients, the right ovarian vein is more probable (80% vs 6%). Case Presentation: A 24-year-old pregnant woman with fetal death (13 - 14 weeks of gestational age) received 600 μg of misoprostol every 12 hours 2 days after the abortion. She had right and left lower quadrant pain. In ultrasound, left ovarian thrombosis was reported, and abdominal computed tomography (CT) confirmed the diagnosis of ovarian vein thrombosis. Blood analysis of antiphospholipid syndrome was normal. Conclusions: Ovarian vein thrombosis has irreparable and significant side effects; thus, it is important to accurately diagnose it and check its radiographic findings.
: The number of reports of the extrapulmonary manifestations of the coronavirus disease 2019 (COVID-19) is increasing in the literature. The neurological manifestations of COVID-19 in pediatric patients, however, are not well studied. Acute transverse myelitis is among the neurological manifestations usually reported with viral infections. However, the development of transverse myelitis in pediatric patients following COVID-19 is extremely rare. We report a case of acute transverse myelitis in a previously healthy 11 years old female patient with COVID-19 who was asymptomatic before the onset of weakness.
Classifier chains method is introduced recently in multi-label classification scope as a high predictive performance technique aims to exploit label dependencies and, in the meantime, preserving the computational complexity in a desirable level. In this paper, we present a method for chain's order, called Ordered Classifier Chains (OCC), elaborating that the sequence of labels in the chain plays an important role in predictive performance of corresponding multi-label classifiers. OCC proposes making use of correlation of every class label with that of features. OCC renders an ordering of class labels in their descending order. Once the ordering of labels is determined, the features along with every label are fed to binary classifier. In the classifier chain model, the feature space of every binary classifier is extended with the new order of labels. In order to specify association of each sample with the set of class labels, it is given to all of classifiers. Empirical evaluations include an extensive range of multi-label datasets reveal that OCC manages to improve the classification performance compared to existing approaches.
A significant number of hospitalized patients with COVID-19 are prone to thromboembolic events including deep vein thrombosis, pulmonary embolism, cerebrovascular accident, and myocardial infarction. However, some COVID-19 patients have a higher risk of bleeding that is associated with an increased risk of mortality. We report a 71-year-old woman who was a confirmed case of COVID-19 admitted for pulmonary involvement and complicated acute renal failure. During hospitalization, she suffered from a sudden onset of severe pain in the lower left abdomen as well as a sudden drop in blood pressure and hemoglobin. Haematomas in the left rectus and obturator internus muscle were observed in abdominal and pelvic computed tomography scan. Signs of haemorrhage were also seen in the anterolateral aspect of the bladder with extension to the paracolic, subdiaphragmatic, perihepatic and, perisplenic spaces. The patient was totally recovered by a conservative approach. Bleeding tendency could be a serious complication, especially, in COVID-19 patients with complicated renal failure that receive heparin prophylaxis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
