Stafne bone cavity : magnetic resonance imaging

A case of Stafne bone cavity (SBC) affecting the body of the mandible of a 51-year-old female is reported. The imaging modalities included panoramic radiograph, computed tomography (CT) and magnetic resonance (MR) imaging. Panoramic radiograph and CT were able to determine the outline of the cavity and its three dimentional shape, but failed to precisely diagnose the soft tissue content of the cavity. MR imaging demonstrated that the bony cavity is filled with soft tissue that is continuous and identical in signal with that of the submandibular salivary gland. Based on the MR imaging a diagnosis of SBC was made and no further studies or surgical treatment were initated. MR imaging should be considered the diagnostic technique in cases where SBC is suspected. Recognition of the lesion should preclude any further treatment or surgical exploration

Duretovo krvarenje: rijetka komplikacija ishemijskog moždanog udara u području središnje moždane arterije - Prikaz slučaja

We report on an unusual case of brainstem Duret hemorrhage after ischemic stroke in the anterior circulation. The patient showed a clinical and neuroradiological picture of an acute and malignant middle cerebral artery infarct with increased intracranial pressure followed by a brainstem hemorrhage. The report suggests that the descending transtentorial herniation of any etiology might be complicated by a Duret hemorrhage.Opisuje se rijedak slučaj Duretova krvarenja moždanoga debla nakon ishemijskog moždanog udara u prednjem krvotoku. Bolesnik je pokazivao kliničku i neuroradiološku sliku akutnog i zloćudnog infarkta središnje moždane arterije uz povišen intrakranijski tlak, nakon čega je uslijedilo krvarenje u moždanom deblu. Ovaj prikaz ukazuje na to da se Duretovo krvarenje može pojaviti kao komplikacija kod silazne transtentorijske hernijacije bilo koje etiologije

Effects of Baking, Roasting and Frying on Total Polyphenols and Antioxidant Activity in Colored Chickpea Seeds

ABSTRACT Chickpea lines with colored testa (seed coat) contain high levels of polyphenolic compounds that exhibit high levels of antioxidant activity. In a previous study, we showed that common processing procedures, such as soaking and cooking, decrease the levels of these bioactive compounds and subsequent overall antioxidant activity. The observed reduction in total phenolic content was due to the movement of polyphenols from the seed coat to the soaking or cooking water. Here, the effects of baking, roasting and frying processes were examined in relation to total phenolic content (TPC), total flavonoid content (TFC) and ferric-reducing ability of plasma antioxidant activity (FRAP AA) of colored chickpea seeds. Baked, fried and roasted colored chickpea seeds had significantly higher levels of TPC, TFC and FRAP AA than regular cream-and beige-colored seeds subjected to the same treatments. In contrast to our previous results with soaking and cooking, baking, frying and roasting retained most of the TPC, TFC and FRAP AA in the final products. Thus, colored chickpeas subjected to these three processing methods might be considered a functional food in addition to its traditional role of providing dietary proteins

White matter changes in multiple sclerosis: correlation of q-space diffusion MRI and 1H MRS

Objective To explore the diagnostic usefulness of high b-value diffusion magnetic resonance brain imaging (“q-space” imaging) in multiple sclerosis (MS). More specifically, we aimed at evaluating the ability of this methodology to identify tissue damage in the so-called normal-appearing white matter (NAWM). Design In this study we examined the correlation between q-space diffusion imaging and magnetic resonance spectroscopy (MRS)-based two-dimensional 1H chemical shift imaging. Eight MS patients with different degree of disease severity and seven healthy subjects were scanned in a 1.5-T magnetic resonance imaging (MRI) scanner. The MRI protocol included diffusion tensor imaging (DTI) (with bmax of 1000 s/mm2), high b-value diffusion-weighted imaging (with bmax of 14,000 s/mm2) and 2D chemical shift imaging. The high b-value data set was analyzed using the q-space methodology to produce apparent displacement and probability maps. Results We found that the q-space diffusion displacement and probability image intensities correlated well with N-acetylaspartate levels (r=.61 and .54, respectively). Furthermore, NAWM that was abnormal on MRS was also found to be abnormal using q-space diffusion imaging. In these areas, the q-space displacement values increased from 3.8±0.2 to 4.6±0.6 μm (P<.02), the q-space probability values decreased from 7.4±0.3 to 6.8±0.3 (P<.002), while DTI revealed only a small, but still significant, reduction in fractional anisotropy values from 0.40±0.02 to 0.37±0.02 (P<.05). Conclusion High b-value diffusion imaging can detect tissue damage in the NAWM of MS patients. Despite the theoretical limitation of this method, in practice it provides additional information which is clinically relevant for detection of tissue damage not seen in conventional imaging techniques
