ABMMNC implantation could be a safe alternative to achieve therapeutic angiogenesis in patients with thromboangiitis obliterans and critical limb ischemia refractory to other treatment modalities.
In this study, measurements of dose-area product (DAP) and entrance dose were carried out simultaneously in a sample of 162 adult patients who underwent different interventional examinations. Effective doses for each measurement technique were estimated using the conversion factors that have been determined for specific X-ray views in a mathematical phantom. Exposure conditions used in clinical practice never match these theoretical models exactly, and deviations from the assumed standard conditions cause uncertainties in effective dose estimations. Higher effective dose values are found if the air kerma results are used rather than DAP readings, both for patient and Rando phantom studies. Comparison of DAP, fluoroscopy times and skin doses were made with published data. DAP measurement for the effective dose calculation and thermoluminescent dosimeter for the skin dose estimates are found to be the most reliable methods for patient dosimetry.
In sonographic examination, the presence of the main renal artery with a diameter smaller than usual in a kidney with normal dimensions is indicative of the presence of an accessory renal artery. Taking this into account, we can obtain higher rates of detection of accessory renal arteries in sonographic examinations.
Objective: Hypothyroidism is a metabolic condition that can lead to cognitive and behavioral deficits in children and adolescents. However, there is less evidence about subclinical hypothyroidism (SH) as a risk factor for neuropsychological disorders in childhood. The aim of thisstudy was to evaluate cognitive functions like active/passive attention, maintaining attention, and response inhibition in pediatric patients with SH.Methods: Seventeen patients (between 7-17 years old) with SH were tested with the Stroop test, Verbal Fluency test and the sub-tests of the Wechsler intelligence scale for children-Revised (WISC-R). SH diagnosis was based on the mild increase of serum thyrotropin (TSH) level together with a normal serum free thyroxine level and an exaggerated TSH response to thyrotropin-releasing hormone. Results: Out of seventeen cases, 10 (59%) were girls and 7 (41%) were boys. Six cases were obese and 5 were overweight. The children in the SH group, as compared to the control group, obtained significantly lower scores on both the Digit Span subtest of the WISC-R and the Stroop subtests, which are sensitive to attention. No significant differences were found between the SH group and the healthy controls in verbal fluency and encoding tests. Conclusion: In this study, pediatric patients with SH showed poor performance in tests measuring attention. Therefore, we want to stress the importance of close collaboration between pediatric endocrinology and child and adolescent psychiatry departments. Conflict of interest:None declared.
An endovascular intervention is a feasible alternative to the technically challenging conventional surgery for the treatment of traumatic vertebral arterial lesions. This report describes a rare case involving a 22-year-old patient with a traumatic vertebral arterial pseudoaneurysm and multiple arteriovenous fistulas which were successfully sealed using the endovascular stent-graft technique.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
