Show Abstract
Hide Abstract
Primary aldosteronism (PA), characterized by an excessive production of aldosterone, affects 5-13 % of patients with hypertension. Accurate strategies are needed for the timely diagnosis of PA to allow curability and prevention of excessive cardiovascular events and related damage. This study aimed to evaluate the usefulness of semiquantification of (131)I-6?-iodomethyl-norcholesterol (NP-59) single photon emission computed tomography (SPECT)/CT in differentiating aldosterone-producing adenoma (APA) from idiopathic adrenal hyperplasia (IAH) and in predicting clinical outcomes after adrenalectomy.

Hide Abstract
A 56-year-old woman, who had already suffered from systemic sclerosis and primary biliary cirrhosis, was presented with progressive pain at the right lower quadrant of abdomen, lower-grade fever, and leukocytosis for 4 days. Blood cultures did not yield pathogens. Abdominal ultrasonography revealed a right iliac artery aneurysm compressing the right kidney resulting in right hydronephrosis. 67Ga SPECT/CT demonstrated an intense hot area at the right common iliac artery, suggestive of an infected aneurysm. Contrast-enhanced CT showed concordant findings. This case illustrates the value of 67Ga SPECT/CT in discriminating pathologic uptake of the abdomen from physiologic activity of the bowels.

This study examines the utilization patterns of myocardial perfusion imaging (MPI) and cardiac catheterization (CC) under Taiwans national health insurance program. This study used the longitudinal health insurance database with 1,000,000 people were randomly selected from the national health insurance research database. This study obtained data from these patients with coronary artery disease (CAD) and comparison with the utilization of MPI or CC between 2005 and 2009. The incidence of CAD did not significantly change, while the prevalence of CAD, utilization of MPI, and the utilization of CC for the CAD patients increased annually. There were the most CAD patients in Northern Taiwan (43.5%), followed by Southern, Central, and Eastern Taiwan. The utilizations of both of MPI (12.7 per 100 CAD patients) and CC (10.6 per 100 CAD patients) were most frequent in Northern Taiwan followed by Southern, Central, and Eastern Taiwan. However, the MPI/CC ratio was 1.20 in Northern Taiwan, followed by Southern, Central, and Eastern Taiwan (0.88, 0.64, and 0.52, respectively, P = 0.0008). The use of MPI was higher than CC only in Northern Taiwan. MPI may be underutilized to serve the role of gatekeeper for CC in the other regions.

Hide Abstract
Myoclonic astatic epilepsy (MAE) is characterized by multiple seizure types, which are often refractory. Although vagus nerve stimulation (VNS) is an alternative treatment for medically intractable seizures, its exact mechanism of action remains unclear. Herein, we report the case of a 4-year-old boy with intractable MAE who has been in a seizure-free status for 2 years and 3 months since 6 months after the implantation of a vagus nerve stimulator (Model 103, Cyberonics, Inc., Houston, TX). Various test results 6 months after VNS were compared with those before VNS. Results of an electroencephalograph revealed disappearance of epileptiform discharges and an increased beta-gamma spectrum rhythm. The brain diffusion-tensor imaging showed an increased ratio of fraction anisotropy in the right fimbria-fornix, indicating improved diffusion of the white matter tract, and (18)F-fluorodeoxyglucose positron emission tomography revealed globally improved cerebral glucose metabolism. His cognitive and social-emotional performances also improved at 2 years after VNS. To the best of our knowledge, this is the first report to describe the effects of VNS on fimbria-fornix and glucose metabolism in MAE.

Hide Abstract
Niemann-Pick type C disease (NPC) is a rare autosomal recessive lipid storage disorder caused by impaired cellular functions in processing and transporting low-density lipoprotein-cholesterol. In this report, we present magnetic resonance imaging (MRI), magnetic resonance spectrography (MRS) and 18-fluoro-2-deoxyglucose positron emission tomography (PET) imaging results for a 22-year-old male NPC patient. The patients two MRI studies (at age 19 years and 22 years) demonstrated progressive changes of brain atrophy that were more prominent at the frontal lobes, and hyperintense signals in bilateral parietal-occipital periventricular white matter. MRS (at age 19 years) revealed no significant decrease in N-acetyl aspartate/choline ratio in the left frontal central white matter. PET (at age 22 years) showed significant bilateral hypometabolism in the prefrontal cortex and dorsomedial thalamus, and hypermetabolism in the parietal-occipital white matter, lenticular nucleus of the basal ganglia, cerebellum and pons. The imaging findings noted by MRI, MRS and 18-fluoro-2-deoxyglucose PET offered a possible supplementary explanation for the clinical neurological symptoms of this NPC patient.

Hide Abstract
A 14-year-old girl, who had been suffering from intermittent fevers for 2 months, developed painful erythematous plaques on the lower extremities. Laboratory data revealed elevated C-reactive protein, lactate dehydrogenase, and aspartate aminotransferase/alanine aminotransferase (AST/ALT). Blood and urine cultures were negative. CT showed hepatosplenomegaly. F-18 FDG PET revealed multiple patchy uptakes on the subcutaneous surfaces residing mainly at the lower trunk and extremities. The PET images and clinical manifestations appeared indistinguishable from those due to panniculitis while the pathology from skin biopsy demonstrated panniculitis-like T-cell lymphoma. She received chemotherapy and the follow-up PET showed significant resolution of previous abnormal uptakes from the subcutaneous lesions.

Show Abstract
Hide Abstract
Thymic carcinoma is a rare anterior mediastinal malignancy. Most patients present initially with chest pain, cough or dyspnea. Asymptomatic patients account for less than one third of the total cases. Thymic carcinoma is aggressive and tends to metastasize to the lymph nodes, lungs, and bones, and less commonly to the liver, spleen, brain, and adrenal glands. We present a 49-year-old man who received abdominal ultrasound and magnetic resonance imaging for a health checkup, during which, a necrotic hepatic tumor was found incidentally. Fluorodeoxyglucose (FDG) positron emission tomography was performed to search for the primary site of malignancy, and lobulated FDG hypermetabolic lesions in the anterior mediastinum were found. The diagnosis of thymic carcinoma with liver metastasis was then confirmed after morphological and immunohistochemical studies of hepatic and mediastinal biopsy specimens.

What is Visualize?

JoVE Visualize is a tool created to match the last 5 years of PubMed publications to methods in JoVE's video library.

How does it work?

We use abstracts found on PubMed and match them to JoVE videos to create a list of 10 to 30 related methods videos.

Video X seems to be unrelated to Abstract Y...

In developing our video relationships, we compare around 5 million PubMed articles to our library of over 4,500 methods videos. In some cases the language used in the PubMed abstracts makes matching that content to a JoVE video difficult. In other cases, there happens not to be any content in our video library that is relevant to the topic of a given abstract. In these cases, our algorithms are trying their best to display videos with relevant content, which can sometimes result in matched videos with only a slight relation.
