Measurement of vessel stenosis using ultrasonography or magnetic resonance is still the principal method for determining the severity of carotid atherosclerosis and need for endarterectomy.
A ...56-year-old male was admitted to the Cardiovascular Institute "Dedinje" due to a clinically asymptomatic restenosis of the operated left internal carotid artery (ICA). Angiography and magnetic resonance angiography (MRA) in previous hospitalization had revealed occluded right ICA. However, routine duplex ultrasonography revealed a high-grade restenosis (85%) of the left ICA and subocclusion of the right ICA by an ulcerated plaque (confirmed on repeated MRA).
Selective arteriography examination could misrepresent the degree of stenosis especially in patents with the ICA that seems to be occluded. MRA is considered the method of choice for identifying pseudo-occlusions of ICA.
Nanostructured single layered (pure TiO2 , pure ?-Fe2O3 and mixed Fe2O3 /TiO2
with two different oxide ratios, 2 : 3 and 3 : 2) and double layered (TiO2
layer over a Fe2O3 layer) thick films have ...been fabricated by screen printing
technology on a glass substrate. The pastes used for film preparation were
obtained by adding an organic vehicle to the oxide powders together with a
small percentage of binding glass frit. Samples were dried up to 100 ?C and
sintered at 650 ?C/60 minutes. Structural, morphological and optical studies
have been carried out using XRD, SEM analyses and UV/Vis spectroscopy. The
prepared pure and mixed Fe2O3 /TiO2 thick films had a homogenous
nanostructure without secondary phases. Indirect band gaps were determined
from the measured transmission spectra and the obtained values are in the
range of literature data.
Glucose-galactose malabsorption (GGM) is a rare autosomal recessive disorder of intestinal transport of glucose and galactose, leading to watery diarrhea, dehydration, failure to thrive, or early ...death. We report a female newborn with GGM, whose clinical diagnosis was confirmed by mutational analysis of the SGTL1 gene. Bilateral nephrolithiasis was discovered after an episode of hematuria. Metabolic causes of nephrolithiasis were not found. The most likely explanation for the development of nephrolithiasis is chronic diarrhea leading to dehydration and highly concentrated urine. High fluid intake and rigorous prevention of dehydration is therefore advised for these patients. Furthermore, life-long monitoring of their renal status, including regular ultrasound examinations, is warranted.
Abstract Patient was admitted for endarterectomy of the left internal carotid artery. Echocardiography showed mitral stenosis with mitral valve area of 1.4 cm2 . Since the patient's functional ...capacity could not be determined due to left-sided hemiplegia, it was decided to perform high-dose dobutamine stress-echocardiography in order to assess the patient's hemodynamics during stress. Gradients over mitral valve increased from 32/10 mmHg at baseline to 43/16 mmHg at 40 mcg/kg/min dobutamine infusion. Preoperative and 24 hour perioperative hemodynamic variables were monitored by Swan–Ganz catheher, and their values did not change significantly as compared to baseline. Postoperative course was uneventful, and the patient was discharged on the fifth postoperative day.
