A molecular probe carrying anti-tropomyosin 4 for early diagnosis of cerebral ischemia/reperfusion injury

In vivo imaging of cerebral ischemia/reperfusion injury remains an important challenge.We injected porous Ag/Au@SiO_(2) bimetallic hollow nanoshells carrying anti-tropomyosin 4 as a molecular probe into mice with cerebral ischemia/reperfusion injury and observed microvascular changes in the brain using photoacoustic imaging with ultrasonography.At each measured time point,the total photoacoustic signal was significantly higher on the affected side than on the healthy side.Twelve hours after reperfusion,cerebral perfusion on the affected side increased,cerebrovascular injury worsened,and anti-tropomyosin 4 expression increased.Twenty-four hours after reperfusion and later,perfusion on the affected side declined slowly and stabilized after 1 week;brain injury was also alleviated.Histopathological and immunohistochemical examinations confirmed the brain injury tissue changes.The nanoshell molecular probe carrying anti-tropomyosin 4 has potential for use in early diagnosis of cerebral ischemia/reperfusion injury and evaluating its progression.

Recurrent Transient Ischemic Attacks Revealing Cerebral Amyloid Angiopathy: A Comprehensive Case

This case report investigates the manifestation of cerebral amyloid angiopathy (CAA) through recurrent Transient Ischemic Attacks (TIAs) in an 82-year-old patient. Despite initial diagnostic complexities, cerebral angiography-MRI revealed features indicative of CAA. Symptomatic treatment resulted in improvement, but the patient later developed a fatal hematoma. The discussion navigates the intricate therapeutic landscape of repetitive TIAs in the elderly with cardiovascular risk factors, emphasizing the pivotal role of cerebral MRI and meticulous bleeding risk management. The conclusion stresses the importance of incorporating SWI sequences, specifically when suspecting a cardioembolic TIA, as a diagnostic measure to explore and exclude CAA in the differential diagnosis. This case report provides valuable insights into these challenges, highlighting the need to consider CAA in relevant cases.

Neuroimaging diagnosis for cerebral infarction An 8-year bibliometric analysis

OBJECTIVE： To identify global research trends in neuroimaging diagnosis for cerebral infarction using a bibliometric analysis of the Web of Science. DATA RETRIEVAL： We performed a bibliometric analysis of data retrieval for neuroimaging diagnosis for cerebral infarction containing the key words ＂CT, magnetic resonance imaging, MRI, transcranial Doppler, transvaginal color Doppler, digital subtraction angiography, and cerebral infarction＂ using the Web of Science. SELECTION CRITERIA： Inclusion criteria were： （a） peer-reviewed articles on neuroimaging diagnosis for cerebral infarction which were published and indexed in the Web of Science; （b） original research articles and reviews; and （c） publication between 2004-2011. Exclusion criteria were： （a） articles that required manual searching or telephone access; and （b） corrected papers or book chapters. MAIN OUTCOME MEASURES： （1）Annual publication output; （2） distribution according to country; （3） distribution according to institution; （4） top cited publications; （5） distribution according to journals; and （6） comparison of study results on neuroimaging diagnosis for cerebral infarction. RESULTS： Imaging has become the predominant method used in diagnosing cerebral infarction. The most frequently used clinical imaging methods were digital subtraction angiography, CT, MRI, and transcranial color Doppler examination. Digital subtraction angiography is used as the gold standard. However, it is a costly and time-consuming invasive diagnosis that requires some radiation exposure, and is poorly accepted by patients. As such, it is mostly adopted in interventional therapy in the clinic. CT is now accepted as a rapid, simple, and reliable non-invasive method for use in diagnosis of cerebrovascular disease and preoperative appraisal. Ultrasonic Doppler can be used to reflect the hardness of the vascular wall and the nature of the plaque more clearly than CT and MRI. CONCLUSION： At present, there is no unified standard of classification of cerebral infarction imaging. Detection of clinical super-acute cerebral infarction remains controversial due to its changes on imaging, lack of specificity, and its similarity to a space-occupying lesion. Neuroimaging diagnosis for cerebral infarction remains a highly active area of research and development.

Isolated cerebral mucormycosis that looks like stroke and brain abscess:A case report and review of the literature

BACKGROUND Cerebral mucormycosis is an infectious disease of the brain caused by fungi of the order Mucorales.These infections are rarely encountered in clinical practice and are often misdiagnosed as cerebral infarction or brain abscess.Increased mortality due to cerebral mucormycosis is closely related to delayed diagnosis and treatment,both of which present unique challenges for clinicians.CASE SUMMARY Cerebral mucormycosis is generally secondary to sinus disease or other disseminated disease.However,in this retrospective study,we report and analyze a case of isolated cerebral mucormycosis.CONCLUSION The constellation of symptoms including headaches,fever,hemiplegia,and changes in mental status taken together with clinical findings of cerebral infarction and brain abscess should raise the possibility of a brain fungal infection.Early diagnosis and prompt initiation of antifungal therapy along with surgery can improve patient survival.

Cerebral proliferative angiopathy in pediatric age presenting as neurological disorders:A case report

BACKGROUND Cerebral proliferative angiopathy(CPA)is a rare subtype of arteriovenous malformation.It is extremely rare in pediatric patients and has serious implications for developing children.However,reports of these disorders worldwide are limited,and no uniform reference for diagnosis and treatment options exists.We report the case of a 6-year-old with CPA having predominantly neurological dysfunction and review the literature on pediatric CPA.CASE SUMMARY We report the case of a pediatric patient with CPA analyzed using digital subtraction angiography(DSA)who presented initially with a neurological disorder as the main manifestation.This case is the basis for further discussion of the clinical presentation,pathogenesis,diagnosis,and treatment of CPA in children.After the cerebral DSA,the patient was treated conservatively with sedation,fluid replacement,and blood anticoagulation.She could not cooperate with the followup magnetic resonance imaging examination because of her young age,and her family declined further treatment because of the surgery’s high risk.She was followed up for 3 months;her symptoms did not worsen.CONCLUSION This report of rare pediatric CPA can inform and advance clinical research on congenital cerebrovascular diseases.

CHARACTERISTIC MAGNETIC RESONANCE ENHANCEMENT PATTERN IN CEREBRAL SCHISTOSOMIASIS

Objective To describe the characteristic magnetic resonance imaging (MRI) appearance of cerebral schistosomiasis. Methods Twenty-five patients whose diagnosis of central nervous system (CNS) schistosomiasis had been pathologically (n=8) and clinically (n=17) confirmed were randomly selected. MRI was performed on a Signal 1.5T MRI scanner before and after the intravenous administration of gadopentetate dimeglumine constrast medium. We reviewed the MRI studies obtained at the time of initial presentation, as well as follow-up studies obtained during and after medical treatment. Results Immunological tests in 15 patients indicated schistosomiasis haematobium. Contrast-enhanced T1-weighted images in 22 cases showed central linear enhancement surrounded by multiple enhancing punctate nodules, which appeared “arborized”. Through operation and pathological examination, 8 cases had the granuloma formation of schistosomal eggs extensive surrounded by inflammation and venous congestion. And 17 cases were treated with praziquantel and corticosteroid therapy. And they were followed up for 2 months by taking MRI, which turned out to be complete resolution of the enhancing structure and edema. At follow-up, all the patients’ initial symptoms also resolved. Conclusion The specified MRI enhancement pattern of cerebral schistosomiasis is common in most cases of CNS schistosomiasis, so it should be taken account into the diagnosis of cerebral schistosomiasis.

Study of clinical features of amyloid angiopathy hemorrhage and hypertensive intracerebral hemorrhage

Objective: The purpose of this study was to differentiate between cerebral amyloid angiopathy (CAA) and hypertension (HTN) based on hemorrhage pattern interpretation. Methods: From June 1994 to Oct., 2000, 83 patients admitted to our service with acute intracerebral hemorrhage (ICH) were investigated retrospectively; 41 patients with histologically proven diagnosis of cerebral amyloid angiography and 42 patients with clear history of hypertension were investigated. Results: Patients with a CAA-related ICH were significantly older than patients with a HTN-related ICH (74.0 years vs 66.5 years, P<0.05). There was a significantly higher number of hematomas≥30ml in CAA (85.3%) when compared with HTN (59.5%). No basal ganglional hemorrhage was seen in CAA, but in 40.5% in HTN. In CAA-related ICH, subarachnoid hemorrhage (SAH) was seen in 26 patients (63.4%) compared to only 11 patients (26.2%) in HTN-related ICH. Intraventricular hemorrhage was seen in 24.4% in CAA, and in 26.2% in HTN. Typical features of CAA-related ICH included lobar distribution affecting mainly the lobar superficial areas, lobulated appearance, rupture into the subarachnoid space, and secondary IVH from the lobar hemorrhage. More specifically, multiplicity of hemorrhage, bilaterality, and repeated episodes also strongly suggest the diagnosis of CAA. Multiple hemorrhages, defined as 2 or more separate hematomas in multiple lobes, accounted for 17.1% in CAA-related ICH. Conclusion: There are certain features in CAA on CT and MRI and in clinical settings. To some extent, these features may contribute to distinguishing CAA from HTN related ICH.

State of the art in neurocysticercosis

Diagnosis of neurocysticercosis(NCC)based merely on computed tomography(CT)and magnetic resonance imaging may be doubtful when considering that parenchymal and extraparenchymal NCC are practically distinct clinical and pathophysiological entities.In this letter,we comment on a recent case report by Rizvi et al.

A Review of Human Cysticercosis and Diagnostic Challenges in Endemic Resource Poor Countries

Human cysticercosis is a neglected tropical parasitic zoonotic disease with high public health concerns. Infection of Taenia solium cysticerci in the brain commonly known as neurocysticercosis is a cause to over 29% of all epileptic cases in endemic countries. Unfortunately, this infection can go unnoticed for over 10 years. The objective of this review was to characterize the diagnostic approaches accessible in endemic poor resource countries. The review sought literature from library catalogues and public databases for studies on epidemiology and diagnosis challenges of human cysticercosis. The search key words included “Taenia solium, T. solium cysticercosis, human cysticercosis, neurocysticercosis and diagnosis”. Most of the diagnostic procedures rely on serology. Neuroimaging tools which would confirm and thus enable the assessment of the burden of the disease in endemic countries are rarely used. Therefore assessing the estimate on prevalence and burden of the disease fallacious is owing to the low sensitivity of serological tools and the inhibition of humoral, cellular immune responses, inflammatory reaction and cytokines by the living cysticerci.

Hemorrhagic transformation of ischemic cerebral proliferative angiopathy: A case report

BACKGROUND Cerebral proliferative angiopathy(CPA)is a rare vascular disease characterized by the presence of diffuse vascular proliferation,progressive vascular hyperflow and vasodilation of multiple vessels in the normal brain parenchyma.Unlike cerebral arteriovenous malformations,CPA has a mixed appearance between that of lesions with cell proliferation and endothelial proliferation.To date,the pathogenesis of CPA is unclear,in which changes induced by cortical ischemia in the elastic layer of the blood supply artery and smooth muscle cells may be involved.CASE SUMMARY In this article,we retrospectively analyzed a case of hemorrhagic transformation of ischemic CPA diagnosed by digital subtraction angiography and reviewed the related literature for further exploration of its pathogenesis,diagnosis and treatment.CONCLUSION The information in the present case report may facilitate further clinical research on this cerebrovascular disease.

A Brazilian Case of Tongue Cysticercosis

Human cysticercosis is a neglected tropical parasitic disease due to the tapeworm Taenia solium, common in endemic developing countries. Cysticerci are most commonly found within the central nervous system, but they may also localize in a variety of tissues, including the tongue. Here, we described a case of a 21-year-old woman with a painless, firm, smooth, mucosa-colored nodule located in the lateral region of the tongue was seen by a dentist. An excisional biopsy was performed, and the surgical specimen was examined histomorphologically. The analysis revealed the presence of a cystic lesion containing a serrated larva (Cysticercus cellulosae) as well as a cystic capsule with predominantly mononuclear inflammation. The morphological findings were consistent with the diagnosis of cysticercosis of the tongue. The patient was followed for 22 months and showed no signs of recurrence.
