Abstract We have measured the T 2 * signal response associated with cortical activation due to finger motion at 1.5 Tesla. Both thin slice 2D and 3D images show intensity changes which vary from 2% 32% depending on volunteer, echo time, thickness, in‐plane resolution. The largest change occurred for thinnest slices highest resolution (2 mm 3 ). This is consistent reducing partial volume effects a simple difference in phase between intravascular surrounding parenchyma. No inflow enhancement...
Background and AimsGERD patients frequently complain of regurgitation gastric contents. Medical therapy with proton-pump inhibitors (PPIs) is ineffective in alleviating symptoms, because PPIs do nothing to restore a weak lower esophageal sphincter. Our aim was compare effectiveness increased PPI dosing laparoscopic magnetic sphincter augmentation (MSA) moderate-to-severe despite once-daily therapy.MethodsOne hundred fifty-two GERD, aged ≥21 years 8 weeks therapy, were prospectively enrolled...
Abstract Recent emphasis on high resolution gradient echo studies in functional imaging has led to the conclusion that there are likely three domains of response blood circulation brain when considering field inhomogeneity effects venous pre‐ and during activation. The first is a coherent effect due large or macroscopic vessels order size voxel (ca 200–500 μm most studies). These can lead very signal changes (up 100%). second at venule level 50–200 μm) associated with smaller parenchymal...
Our goal was to determine whether functional MRI on a standard 1.5 T system can localize activation during visual vigilance sustained attention task and this corresponds results described in PET investigation of similar task.Sixteen volunteers were studied using gradient echo technique. A single axial section oriented within stereotaxic coordinate space, 40 mm superior the anterior-posterior commissure line. Images with eyes closed followed by images subject concentration small dim spot....
Abstract Background and Objective : We report the use of new diagnostic parameters based on differential normalized fluorescence (DNF) signals for malignant tumor diagnosis. Study Design/Materials Methods Over 200 measurements endogenous from normal esophageal tissues were performed during routine endoscopy in 48 patients. A pulsed nitrogen‐pumped dye laser was used to provide situ excitation at 410 nm. Direct collection signal emitted by tissue achieved using an intensified photodiode array...
Magnetic sphincter augmentation (MSA) of the lower esophageal restores antireflux barrier in patients with hiatal hernias ≤3 cm. We performed a prospective study undergoing MSA LINX device during repair paraesophageal and over 3 cm axial component.Multicenter, consecutive treated at time >3 cm.200 (110 female) were between March 2014 February 2017 via laparoscopic hernia MSA. Mean age was 59.5 years, mean BMI 29.4. 40% had esophagitis, 20% intestinal metaplasia, 72 77 tested abnormal pH...
Regurgitative gastroesophageal reflux disease (GERD) refractive to medical treatment is common and caused by mechanical failure of the anti-reflux barrier. We compared effects magnetic sphincter augmentation (MSA) with those proton-pump inhibitors (PPIs) in a randomized trial.Patients moderate severe regurgitation (assessed foregut symptom questionnaire) despite once-daily PPI therapy (n = 152) were randomly assigned groups given twice-daily PPIs 102) or laparoscopic MSA 50) at 20 sites,...
A morphine to hydromorphone equivalence ratio of 7:1 has become the accepted standard, but evidence supporting it comes from single dose studies performed before advent patient controlled analgesia (PCA). We compared and use with PCA in bone marrow transplantation patients who required opioids for control severe oral mucositis over several days or weeks. An exploratory analysis clinical records 102 (981 days) used varying periods up 50 suggested a 3:1. To clarify this observation, we studied...
The frequent association of affective disorder and multiple sclerosis raises important aetiological clinical considerations. Reported here are seven patients who presented with symptoms had a preceding history bipolar disorder. hypothesis that illness may be the initial manifestation is discussed reference to relevant epidemiological research on topic.
Background: Pathologic reflux is a common debilitating digestive condition and anti-reflux surgery an effective treatment option. Depending on the specifics of procedure, leads to distinct changes in endoscopic appearance esophagogastric junction (EGJ). This American Foregut Society (AFS) white paper develops nomenclature for describing characteristics EGJ after commonly performed laparoscopic antireflux operations. Methods: The AFS Anti-Reflux Barrier Collaborative analyzed anatomic...
Introduction:The potential of single-incision laparoscopic surgery (SILS) as a less invasive and more cosmetically appealing technique has prompted the expansion its adoption. SILS been shown to be safe feasible alternative traditional multiport cholecystectomy, appendectomy, colectomy, many other procedures. The objective this study is provide an initial report feasibility correcting intestinal malrotation via transumbilical approach.Case Description:A 29-year-old woman presented with...
