TOPIC: Critical Care TYPE: Medical Student/Resident Case Reports INTRODUCTION: A Dieulafoy's lesion was first described by Dr. M. T. Gallard in 1884, but the name followed after a French surgeon, Paul Georges Dieulafoy, who presented three cases of "submucosal arterioles" stomach 1898. Although this is rare lesion, it an important etiology gastrointestinal (GI) hemorrhage that clinicians need t...

PURPOSE We evaluated the utility of magnetic resonance imaging (MRI) and (18)F-fluorodeoxyglucose positron emission tomography/computed tomography ((18)F-FDG PET/CT) for the preoperative staging of invasive lobular carcinoma (ILC) of the breast and compared the results with those of invasive ductal carcinoma (IDC). METHODS The study included pathologically proven 32 ILCs and 73 IDCs. We compa...

OBJECTIVE Lesion procedures for psychiatric indications have a history that spans more than a century. This review provides a brief history of psychiatric surgery and addresses the most recent literature on lesion surgery for the treatment of anxiety and mood disorders. METHODS Relevant data described in publications from the early 1900 s through the modern era regarding lesion procedures for...

BACKGROUND While 68Ga-PSMA PET-MRI might be superior to PET-CT with regard to soft tissue assessment in prostate cancer evaluation, it is also known to potentially introduce additional PET image artefacts. Therefore, the impact of PET acquisition duration and attenuation data on artefact occurrence, lesion detectability, and quantification was investigated. To this end, whole-body PET list mode...

Figure 2 Using the indices of haemoglobin (IHb) colour chart function provided by the Olympus EVIS LUCERA system, the reference IHb values are displayed in yellow, with areas higher than the reference value (hypervascular) displayed in “warm” colours (i. e., orange±red) and hypoperfused areas displayed in “cool” col− ours (blue±grey). IHb charting of the lesion shows a clear vascular map. The l...

Background and Purpose Calcium channel blockers reduce edema due to cerebral ischemia, but little is known about their usefulness in hemorrhage. Therefore, we studied the effect of the calcium channel blocker ('S-)-emopamil in collagenaseinduced hemorrhage. Methods Adult rats had hemorrhagic necrosis induced by the intracerebral injection of 0.4 U of bacterial collagenase. Six groups of rats we...

Behcet`s disease is characterized by small vessel vasculitis and involvement of multiple systems. In neuro-Behcet cases, spinal cord involvement is approximately 10-18%. Spinal cord lesions are often associated with cerebral or brainstem lesions, and isolated spinal cord involvement in Behcet`s disease is very rare. Here, we report a case with an isolated lesion of the cervical spine.

background & aim: according to presence of immune system factors in chronic periapical lesions, hypersensitivity reactions may have some role in pathogenesis of these lesions. up to now, among the factors participating in type i hypersensitivity reaction, only one of them has been studied. so the aim of this study was to evaluate the relationship between the presence of ige & number of mast cel...

introduction: this study evaluated the diagnostic value of the dipyridamole induced electrocardiuogram (ecg) cahnges, comparing with myocardial perfusion imaging. materials and methods: 222 patinets were studied with dipyridamole infusion (based on ecg criteria) as well as dipyridamole-myocardial perfusion imaging (mpi). results: abnormal dipyridamole test and abnormal mpi were noted in 11% and...

introduction: hemangiomas are the most frequent benign tumors of the liver and detecting them from metastasis or other malignant hepatic tumors is of outmost importance. 99mtc- rbc scan is highly specific and is the method of choice for this differentiation. this scintigraphy is performed in planar and spect modes. these two procedures are in agreement most of the times, however since spect is ...
