Hepatopulmonary Syndrome with Right-to-left Shunt in Cirrhotic Patients Using Macro-Aggregated Albumin Lung Perfusion Scan: Comparison with Contrast Echocardiography and Association with Clinical Data.

Objectives: The diagnosis of hepatopulmonary syndrome (HPS) which is a common complication in cirrhotic patients is still subject to debate. This study investigated the association of clinical findings with HPS in cirrhotic patients using macro-aggregated albumin lung perfusion scan (Tc-MAA lung scintigraphy). In addition, comparison between Tc-MAA lung scintigraphy and contrast echocardiography (CEE) in detection of HPS was also performed.

Neurological manifestations related to Crohn's disease: a boon for the workforce.

The neurological manifestations of Crohn's disease and its prevalence are not well known. Here, we report five patients of confirmed Crohn's disease with different neurological presentations. The neurological presentations include anterior ischemic optic neuropathy, myelopathy, posterior reversible encephalopathy syndrome, chronic inflammatory demyelinating polyneuropathy, and chronic axonal sensory and motor polyneuropathy.

Assessment of the Prevalence of Diabetic Gastroparesis and Validation of Gastric Emptying Scintigraphy for Diagnosis.

Objective: Gastroparesis is defined as delayed gastric emptying and is a common medical condition in diabetic patients. Scintigraphy is commonly used as a standard diagnostic procedure for the quantitative assessment of gastroparesis. The aims of this study were to determine an optimum imaging time for the diagnosis of gastroparesis, to assess the prevalence of gastroparesis, to evaluate the correlation between endoscopy and scintigraphy findings as well as the correlation between gastric emptying with patient genders, blood glucose concentration, and functional dyspepsia.

Assessment of Gastric Accommodation in Patients with Functional Dyspepsia by 99mTc-Pertechtenate Single Photon Emission Computed Tomography Imaging: Practical but not Widely Accepted.

Objective: Impaired gastric accommodation is one of the main symptoms in patients with functional dyspepsia. The aim of the present study was to assess gastric accommodation in patients with functional dyspepsia using single photon emission computed tomography (SPECT) imaging.

Methods: Twenty-four patients with functional dyspepsia and 50 healthy volunteers as control group were enrolled in this study.

The association of increased stomach wall radiotracer uptake with prolonged use of omeprazole capsules on myocardial perfusion imaging (MPI) using 99mTc-sestamibi SPECT.

Myocardial perfusion imaging (MPI) is widely used in routine practice for diagnosis and risk stratification of coronary artery disease (CAD). Intense curvilinear activity in the stomach wall of a patient was seen on MPI raw data. This phenomenon was completely dissimilar to the familiar intraluminal gastric reflux of sestamibi.

Topography of gastritis and its severity in 864 first degree relatives of gastric cancer patients.

Objectives: Studies on gastric mucosal histological findings among first degree relatives (FDR) of gastric cancer (GC) patients are scarce. The aim is to evaluate the topography and the severity of gastritis among FDR of GC patients.

Design: A total of 989 subjects who were FDR of GC patients, ages 40-65 years underwent gastroscopies.
