AIDS Presenting as Granulomatous Amebic Encephalitis: PET and MR Imaging correlation

We report a patient in whom GAE secondary to Acanthamoeba was the initial presentation of acquired immunodeficiency syndrome in a 41‐year‐old male, and discuss the FDG positron emission tomography (PET) and magnetic resonance imaging findings that preceded the pathological diagnosis. The PET results provided complementary information when coupled with the MR brain findings. Improved understanding of the clinical and imaging findings of this deadly disease is the best hope for early diagnosis and treatment of this uncommon but deadly disease.

Additionally, hydrothermal synthesis is a common method to control nanostructures. In practice, researchers paid more attention to the direct effect of “useful ions” on morphology or size of nanostructures, e.g. the combination and decomposition processes of H+ and WO42− to form WO3. Unfortunately, the effects of ot...

However, at room temperature they possess a B2-ordered crystal structure and, therefore, exhibit reduced ductility. Guided by thermodynamic calculations, the Al concentration was systematically reduced in MoCrTi-xAl (x&n...

The objective of the study was to identify the relationship between subcortical gray matter (GM) volumes and juvenile myoclonic epilepsy (JME).MethodsWe analyzed the brain magnetic resonance imaging (MRI) scans that were performed during the time of the diagnosis of epilepsy by using voxel-based morphometry (VBM) method. The volumetric three-dimensional sequence was used for structural investigation. The volumes of the thalamus, caudate nucleus, pallidum, and putamen were measured in both hemispheres of patients with JME, patients with generalized tonic–clonic seizures alone (GTCS) (as a disease control group) and he...

Abstract Miltefosine is an alkylphosphocholine compound used primarily for treatment of leishmaniasis that also demonstrates in vitro and in vivo anti-amebic activity against Acanthamoeba species. As such, recommendations for treatment of amebic encephalitis generally include miltefosine therapy. Data supports a minimum amebicidal concentration of at least 16 mcg/mL is required for most Acanthamoeba species. Although there is a high level of mortality associated with amebic encephalitis, a paucity of data regarding miltefosine levels in the plasma and cerebrospinal fluid in vivo exists in the literature. We found ...

In this study, we report the occurrence of the Acanthamoeba belonging to the T4 genotype isolated from nasal and oral swabs of a 15-yr-old man with HIV infection. HIV was confirmed using ELISA kit and RT-PCR assay. The isolated strain showed pathogenic potential using thermo and osmotolerance assays. This patient might be vulnerable to develop GAE or disseminated infections and depending on the immunologic status of the patient, this could be a health threat. Monitoring of such patients, appropriate diagnostic procedures and improved-HIV related care can alter the outcome of such infections. PMID: 28761472 [PubMed]

We describe a case of fatal granulomatous amoebic encephalitis in a patient recently diagnosed to be having SLE, who was receiving corticosteroids, cyclophosphamide, methotrexate, and hydroxychloroquine. The patient presented in an altered sensorium and expired after being hospitalized for 6 days. Postmortem examination of the brain showed extensive areas of necrosis and neutrophilic infiltrate with trophozoites and cysts of Acanthamoeba.
