Neuroimaging in Antisocial Personality Disorder

Neuroimaging has been used in antisocial personality disorder since the invention of computed tomography and new modalities are introduced as technology advances. Magnetic resonance imaging, diffusion tensor imaging, functional magnetic resonance imaging and radionuclide imaging are such techniques that are currently used in neuroimaging. Although neuroimaging is an indispensible tool for psychiatric reseach, its clinical utility is questionable until new modalities become more accessible and regularly used in clinical practice. The aim of this paper is to provide clinicians with an introductory knowledge on neuroimaging in antisocial personality disorder including basic physics principles, current contributions to general understanding of pathophysiology in antisocial personality disorder and possible future applications of neuroimaging.

Ultrasound-guided retrograde tibial access through chronically occluded tibial arteries: a last resort recanalization technique

PURPOSEWe aimed to demonstrate the feasibility of ultrasound (US)-guided retrograde tibial access through chronically occluded tibial arteries as a bailout endovascular recanalization procedure in patients with critical limb ischemia (CLI).METHODSFifty-one CLI patients with failed conventional antegrade tibiopedal recanalization required retrograde tibiopedal access in the same session. In all of these patients, the target tibial artery was chronically occluded in at least the distal half of the cruris. Access attempts were made under real-time US by a single operator experienced in image-guided vascular access procedures. Fluoroscopy was used only as an adjunct during advancement of a 0.018 inch guidewire. If access to the artery was successful by the retrograde route, the occluded artery was usually predilated with a 2 mm balloon, and the standard endovascular treatment was mostly performed through the antegrade route.RESULTSPatients had athereosclerosis (n=35) or Buerger’s disease (n=32) and presented with Rutherford category IV and category V. Successful placement of a guidewire in the occluded artery lumen was achieved in 81% of all patients, whereas, treatment success, i.e. angiographic demonstration of in-line flow at the end of procedure, was achieved in 49%. No significant procedure-related complications were observed. Of 33 limbs with initially successful endovascular treatment, 6 required minor and 1 required major amputation during follow-up.CONCLUSIONUS-guided retrograde access through completely occluded tibial arteries is difficult but feasible. Half of the tibial arteries that could not be recanalized otherwise were converted to successful recanalization by this method

Computed tomography findings of primary epiploic appendagitis as an easily misdiagnosed entity: Case series and review of literature

BACKGROUND: Primer epiploic appendagitis (PEA) is an uncommon condition. METHODS: We retrospectively reviewed the clinical records and computed tomography (CT) findings of 45 patients with PEA. RESULTS: On the basis of physical examination and pain localization, presumptive clinical diagnosis was acute appendicitis (n=13), acute cholecystitis (n=2), acute diverticulitis (n=19), renal colic (n=7) and ovarian pathology (n=4). CONCLUSION: Although it has no characteristic clinical and laboratory features, CT is the best modality for accurate diagnosis of PEA
