Criteria For Diagnosis

Objective: To analyze the imaging characteristics of hemorrhagic cerebral infarction (HI). Methods: The cases were selected from 220 patients with new cerebral infarction who were hospitalized in our hospital from March 2015 to February 2018, of which 34 cases were found with hemorrhagic cerebral infarction. All the selected cases met the criteria for "Diagnosis Points of Various Cerebrovascular Diseases" adopted by the Fourth National Cerebrovascular Diseases Academic Conference of the Chinese Medical Association in 1995, and were confirmed by cranial CT and/or GE1.5HDX MRI scans as Hemorrhagic cerebral infarction. Retrospectively analyze the clinical data, clinical manifestations, brain CT, GE1.5HDX magnetic resonance examination, and clinical data of 34 patients with HI, and analyze their short-term prognosis, HI occurrence time, type of bleeding, infarct area, incidence site, arteries The blood supply and imaging performance were analyzed by statistical X2 test to analyze the imaging characteristics of hemorrhagic cerebral infarction. Results: 1. 34 patients with HI in this group accounted for 15.45% of the cerebral infarction in the same period, including 16 males and 18 females. The ages ranged from 45 to 86 years, with an average of 68.09 ± 10.41 years. 2.34 cases of HI included cerebral embolism in 26 cases (76.47%), cerebral thrombosis in 7 cases (20.58%), lacunar infarction in 1 case (2.94%), cardiogenic cerebral embolism in 22 cases (64.71%), and history of atrial fibrillation. Fourteen patients (41.18%) and 24 patients with large infarction (70.59%). Conclusions: Embolization, occlusion, recanalization, and establishment of collateral circulation are closely related to the occurrence of HI. For patients with cardiogenic cerebral embolism and large-scale cerebral infarction, regardless of whether the clinical symptoms are exacerbated, attention should be paid to cerebral infarction.

Cardiac Abnormalities

Cardiovascular pathology is one of the urgent problems of modern medicine, including children. The peculiarity of most cardiovascular diseases in children lies in their prolonged formation, tendency to chronic course, less apparent clinical manifestations in the first stages of the disease. Objective. In childhood, large-scale clinical epidemiological studies have not yet become widespread. But the available statistics allows analyzing trends and patterns that reflect the features of cardiovascular pathology in childhood, its role in health of the child population, which was the objective of this paper. Materials and methods. The analysis of medical and statistical documents of 1825 children aged 0–18 years followed up for cardiomyopathies of dysplastic genesis (DGC) in healthcare facilities of Kharkiv. The indications for following up were clinical symptoms and cardiac ultrasound findings during outpatient or inpatient examination in the absence of organic cardiovascular diseases. Results. Most often, clinical manifestation and, accordingly, diagnosis were observed from 4 to 11 years. Most minor cardiac abnormalities persist over the lifetime, and clinical significance may increase with age, contributing to the development of pathology or becoming a risk factor for cardiac pathology. Conclusions. The structure of minor cardiac abnormalities among the children of the dispensary group is heterogeneous: prolapse of the mitral valve (mostly isolated), abnormal chords of the left ventricle and open foramen ovale are most frequently recorded; prolapse of other valves and aneurysms of the atrial septum are very rare. Primary diagnosis of minor cardiac abnormalities mainly takes place at age 4 to 11 years. Summarizing the findings, it can be noted that minor cardiac abnormalities have a relatively high detection rate and constitute a large and heterogeneous dispensary monitoring group.

Objective: High-risk factors of the patients with moyamoya disease (MMD) were analyzed to provide the basis for prediction and management of cerebral infarction after direct bypass surgery in adult MMD. Methods: 1. Retrospective analysis of clinical data was collected from adult MMD patients (n = 250) following superficial temporal artery-middle cerebral artery bypass surgery performed in our hospital from July 2013 to December 2017. Of the 250 patients, all underwent hemispherical bypass surgery, and bilateral surgery was performed on 14 patients. 2. Clinical data were analyzed based on sex, age, hypertension, diabetes, smoking history, history of alcohol use, presurgery cerebral infarction, transient ischemic attack, classification of clinical manifestations, clinical typing, Suzuki stage of surgical side, Suzuki stage of nonoperative side, preoperative Modified Rankin Scale (MRS), and lesions of the postoperative cycle or not. Results: 1. There were significant differences in classification of clinical manifestations, preoperative infarction, clinical typing, and Suzuki stage of nonoperative side (p < 0.05). 2. Logistic regression analysis showed that the independent factors affecting postoperative cerebral infarction were preoperative infarction and the Suzuki stage of nonoperative side (p < 0.05). The preoperative infarction (B 1.431, OR 4.184, 95% CI 1.217–14.382) and the Suzuki stage of nonoperative side (B 0.495, OR 1.640, 95% CI 1.207–2.227) were both risk factors. Conclusion: The possibility of a new cerebral infarction in postoperative patients with a history of cerebral infarction was greater. The Suzuki stages (I–VI) of the nonoperative side was higher and associated with an increased probability of cerebral infarction after surgery.

Abstract Introduction Venous cerebral infarction is a serious complication after meningioma resection. To reduce the incidence of venous infarction, we identified risk factors for postoperative venous cerebral infarction after surgical resection of meningioma in patients with clinical symptoms.Methods The clinical and imaging data of 1127 patients with intracranial meningiomas who underwent resection in our hospital were retrospectively collected and analyzed. Venous cerebral infarction was evaluated by postoperative imaging and clinical manifestations. Univariate and multivariate analyses were performed to identify risk factors associated with venous cerebral infarction.Results Overall, 3.3% (37/1127) of patients experienced symptomatic venous cerebral infarction after meningioma resection. Multivariate analysis revealed superficial meningioma, moderate to severe peritumoral edema, peritumoral critical vein and WHO grade II-III as independent predictors of a postoperative venous cerebral infarction. After timely intervention, the symptoms were clearly alleviated in one month, and the prognosis was good, but injury to key veins could cause irreversible neurological disorders.Conclusions Intraoperative protection of veins is the primary way to prevent venous cerebral infarction. The present study identified several significant and independent risk factors for postoperative venous infarction, thereby enabling the identification of high-risk patients who require special attention during clinical and surgical management.

Although Toxocara canis is known to cross the blood-brain barrier, central nervous system involvement is uncommon. Clinical manifestations vary and include cerebral infarction, meningoencephalitis, myelitis, vasculitis or seizure. However cerebral infarction and meningoencephalitis rarely occur simultaneously. We report a case of multiple cerebral infarction combined with eosinophilic meningoencephalitis in a patient with neurotoxocariasis. After control of increased intracranial pressure and treatment with albendazole and steroid, the patient’s clinical symptoms improved markedly.

Abstract Funding Acknowledgements Type of funding sources: Public grant(s) – National budget only. Main funding source(s): UKRI CDT in AI for Healthcare http://ai4health.io and British Heart Foundation Background  Data curation is an important process that structures and organises data, supporting research and the development of artificial intelligence models. However, manually curating a large volume of medical data is a time-consuming, repetitive and costly process that puts additional strain on clinical experts. The curation becomes more complex and demanding as more data sources are used. This leads to an introduction of disparity in the data structure and protocols.  Purpose  Here, we propose an automatic framework to curate large volumes of heterogenous cardiac MRI scans acquired across different sites and scanner vendors. Our framework requires minimal expert involvement throughout and works directly on DICOM images from the scanner or PACS.  The resulting structured standardised data allow for straightforward image analysis, hypothesis testing and the training and application of artificial intelligence models.  Methods  It is broken down into three main components anonymisation, cataloguing and outlier detection (see Figure 1). Anonymisation automatically removes any identifiable patient information from the DICOM image attributes. These data are replaced with anonymised labels, whilst maintaining relevant longitudinal information from each patient. DICOM attributes are also used to automatically group the different images according to imaging sequence (e.g. CINE, Delayed-Enhancement, T1 maps), acquisition geometry (e.g. short-axis, 2-chamber, 4-chamber) and imaging attributes (e.g. slice thickness, TE, TR), for easier querying. The sorting characteristics are flexible and can easily be defined by the user. Finally, we detect and flag, for subsequent manual inspection, any outliers within those groups, based on the similarity levels of chosen DICOM attributes. This framework additionally offers interactive image visualisation to allow users to assess its performance in real time.  Results  We tested the performance of ACUR CMRI on 26,668 CMR image series (723,531 images) from 858 patient examinations, which took place across two sites in four different scanners. With an average execution time per patient of 100 seconds, ACUR was able to sort imaging data with 1191 different sequence names into 43 categories. The framework can be freely downloaded from https://bitbucket.org/cmr-ai-working-group/acur/.  Conclusions  We present ACUR, an automatic framework to curate large volumes of heterogeneous cardiac MRI data. We show how it can quickly and automatically curate data, grouping it according to desired imaging characteristics defined in DICOM attributes. The proposed framework is flexible and ideally suited as a pre-processing tool for large biomedical imaging data studies.

Abstract The study was to analyze the clinical features and imaging characteristics of moyamoya disease (MMD) and to explore the significance of multi-model imaging in the diagnosis of MMD. A retrospective analysis of the clinical features, imaging characteristics, and treatment of 78 adult MMD patients enrolled from March 2010 to March 2013 was performed. The MMD patients in our series were between 23 and 53 years old, and the male to female ratio was 4:1. The main clinical manifestations were sensory abnormalities, headache, and motor dysfunction, depending on the type of MMD. Intracerebral hemorrhage (ICH) was detected in 54 patients (69.2％), cerebral infarction in 20 (25.6％), and ICH together with cerebral infarction in 4 (5.1%). Using computed tomography angiography (CTA), magnetic resonance angiography (MRA), and digital subtraction angiography (DSA), stenotic or occlusive lesions were observed in the internal carotid artery, anterior cerebral artery, and middle cerebral artery. Aneurysms accompanying MMD were found in 17 of the patients (21.8％). Ultimately, 21 patients underwent multiple burr-hole surgery and 57 underwent bypass surgery with or without temporalis muscle sticking. Fourteen patients underwent aneurysm embolization. The clinical manifestations of MMD vary, though the most common is ICH. DSA is the gold standard method for the diagnosis of MMD, and should be performed as early as possible in clinically suspected cases. CTA and MRA are non-invasive techniques used for MMD patient screening and follow-up.

ObjectiveTo analyze the clinical manifestations, imaging, electroencephalography, treatment, and prognosis of 35 cases of autoimmune glial fibrillary acidic protein astrocytopathy (GFAP-A) in children.MethodsChildren hospitalized in the Department of Neurology, Hunan Children’s Hospital, China, between January 2015 and June 2021, owing to autoimmune diseases of the central nervous system were subjected to a cell-based assay (CBA). The assay identified 40 children positive for GFAP-immunoglobulin (Ig)G antibodies in the serum and/or the cerebrospinal fluid. Based on clinical manifestations and imaging characteristics, five children who were only positive for GFAP-IgG antibodies in serum were excluded, and the remaining 35 children were diagnosed with autoimmune GFAP-A. The clinical data derived from the 35 children were retrospectively analyzed.ResultsA total of 35 children, including 23 males and 12 females with a mean age of 6.3 ± 0.6 years, manifested clinical symptoms of fever (62.9%), headache (42.9%), convulsions (42.9%), abnormal mental behavior (51.4%), disorders of consciousness (54.3%), visual disturbance (22.9%), ataxia (11.4%), paralysis (40%), and autonomic dysfunction (25.7%). One child exhibited only the clinical symptom of peripheral facial nerve palsy. Eleven out of 35 children were also positive for other antibodies. In addition to the common overlapping autoimmune syndromes, one case of autoimmune GFAP-A also manifested as Bickerstaff’s brainstem encephalitis. Linear periventricular enhancement upon MRI was significantly less frequent in children (8.5%) than in adults. In pediatric patients, MRI contrast enhancement was principally seen in the meninges and brain lobes. Although repeated relapse (17.1%) and sequelae symptoms (20%) occurred in some cases, most children showed a favorable prognosis. Spearman’s rank correlation showed that the antibody titer was not significantly associated with the severity of the initial disease conditions.ConclusionsThe disease diagnosis in children seropositive for GFAP antibodies only should receive a comprehensive diagnosis based on their clinical symptoms, imaging, electroencephalographic characteristics, and treatment responses. Some patients with relapses should receive repeated gamma globulin and corticosteroid therapy or the addition of immunosuppressants to their therapeutic regimen, and slow-dose tapering of corticosteroids and extended treatment are recommended for patients with overlapping autoimmune syndromes.

Background and Objective: Rosai-Dorfman disease (RDD) are usually misdiagnosed because of rarity and nonspecific clinical and radiological features. The aim of our study is to explore the clinical and imaging characteristics of RDD to improve diagnostic accuracy. Methods: Clinical and imaging data in 10 patients with RDD were retrospectively analyzed. 7 patients were underwent CT scanning and 3 patients were underwent MR examination. Results: 8 (8/10) patients presented with painless enlarged lymph nodes (LNs) or mass. 3 cases were involved with LNs, 5 cases were involved with extra-nodal tissues, and the remaining 2 cases were involved with LNs and extra-nodal tissue simultaneously. In enhanced CT images, enlarged LNs displayed mild or moderate enhancement, and 2 cases showed heterogeneous ring-enhancement. MR features of 3 patients with extra-nodal RDD, 2 cases showed a mass located in the subcutaneous and anterior abdominal wall respectively, and 1 case showed an intracranial mass. Besides, all lesions showed high signal foci on DWI images, and were characterized by marked heterogeneous enhancement with blurred edge. The dural/fascia tail sign and dilated blood vessels could be seen around all the lesions on enhanced MRI. Radiological features of 2 cases with LN and extranodal tissue involved, one case presented with the swelling and thickening of pharyngeal lymphoid ring and nasopharynx, meanwhile with enlarged LNs in bilateral submandibular area, neck and abdominal cavity, and also companied with osteolytic lesion in right proximal humerus. All these LNs displayed mild and moderate enhancement on CT images. Another case showed enlarged LNs in bilateral neck accompanied with soft tissue mass in the sinuses. Conclusions: RDD occurred commonly in young and middle-aged men and presented with painless enlarged LNs or mass.RDD had a huge diversity of imaging findings, which varied with different location. The radiological features, such as small patches of high signal foci in the masses on DWI images, heterogeneous enhancement and blood vessels around the masses, are helpful in diagnosis of extranodal RDD.

Cerebrovascular diseases are a problem of the world today, and according to the forecast, the problem of the near future arises. The main risk factors for the development of ischemic disorders of the cerebral circulation include oblique and aging, arterial hypertension, smoking, diabetes mellitus and heart disease. An effective strategy for the prevention of cerebrovascular events is based on the implementation of large-scale risk control measures, including the use of antiagregant and anticoagulant therapy, invasive interventions such as atheromectomy, angioplasty and stenting. In this connection, the efforts of neurologists, cardiologists, angiosurgery, endocrinologists and other specialists are the basis for achieving an acceptable clinical outcome. A review of the SF-36 method for assessing the quality of life in patients with the effects of transient ischemic stroke is presented. The assessment of quality of life is recognized in world medical practice and research, an indicator that is also used to assess the quality of the health system and in general sociological research.

Introduction: Epididymo-orchitis is a common urological disease among men. Little is known about the clinical and epidemiological aspects of the disease in Iran. Thus, the present study was aimed to investigate the etiology, clinical sequelae and risk factors of patients with epididymo-orchitis in Tehran, Iran. Materials and Methods: Patients presenting with epididymo-orchitis were prospectively analyzed in order to study the etiology and pattern of the disease. Bacteriological, molecular and serological tests were undertaken to look for Chlamydia trachomatis, Neisseria gonorrhoeae, Brucella spp., Mycoplasma spp, and other bacteria. Results: Fifty patients with epididymo-orchitis were evaluated according to their clinical symptoms, duration of symptoms, physical examination, and laboratory studies. The mean age of the patients was 53 years. Fever, dysuria, pain in the flanks, urinary frequency and discharges occurred in 58.0%, 50.0%, 50.0%, 28.0% and 6.0%, respectively. Bacterial pathogen was identified in 26% (13/50) of patients by urine culture. Escherichia coli was the etiological agent in 11/13 patients (84.6%). Two out of 50 patients (4.0%) were also positive for Chlamydia trachomatis. Two samples were serologically positive for Brucella spp. High Mean age, fever, urinary frequency, history of the underlying disease and history of urinary tract infections were found to have a significant association with the positive bacteriologic urine culture (P<0.05). Conclusions: The most common clinical manifestations were fever, dysuria, and abdominal pain. E. coli and C. trachomatis were the major causative agents. Use of a set of diagnostic approaches including clinical symptoms, urine culture and more precise techniques such as PCR should be taken into consideration for the definitive diagnosis.
