[en] With the ever increasing trend of using cross-section imaging in today's era, incidental detection of small solid renal masses has dramatically multiplied. Coincidentally, the number of asymptomatic benign lesions being detected has also increased. The role of radiologists is not only to identify these lesions, but also go a one step further and accurately characterize various renal masses. Earlier detection of small renal cell carcinomas means identifying at the initial stage which has an impact on prognosis, patient management and healthcare costs. In this review article we share our experience with the typical and atypical solid renal masses encountered in adults in routine daily practice.
[en] Fischer-344 male adult (4-6 mo) and aged (24-26 mo) rats were exposed to 0-3.0 ppm O3 for 8h, sacrificed immediately, and O2 consumption, 1C14-glucose metabolism and G6PDH activity were determined. For O2 consumption, the exp to 0.5 ppm O3 produced a stimulation in both age groups. Decrements in O2 consumption were only evident in aged rats after 1.5 and 3.0 ppm. Glucose metabolism showed a marked difference rats were 40% adult rats. Control values in aged rats were 40% of adults. Exp to 0.5 ppm was stimulatory in adults and aged, while 1.5 and 3.0 pp, decreased glucose metabolism in both groups. No age-related difference in G6PDH activity between control and exposed was seen. However, in both age groups, 0.5 ppm O3 resulted in a significant increase in activity (33-41%)l 1.5 and 3.0 ppm were without effect. The combined results show a biphasic response of adult and aged lung to severe, acute O3 exp. One-half ppm O3 for 8h is stimulatory for all three parameters examined in both age groups. Three ppm O3 inhibits O2 consumption and glucose metabolism in both age groups but is ineffective on G6PDH activity
[en] Ultrasonography of thyroid gland is a frequently performed investigation. Many of the diffuse thyroid pathologies are associated with altered vascularity. In view of potential applications and scant available data, there is a need to find normal values of Doppler indices of superior thyroid artery (STA). To find the normal range of Doppler indices like mean peak systolic velocity (PSV), resistivity index (RI), and pulsatility index (PI) of STA in clinically euthyroid adult individuals. Prospective cross-sectional observational study. A study was done in the Department of Radiodiagnosis of a tertiary care hospital, involving clinically euthyroid adult volunteers. Ultrasonography of the thyroid gland with Doppler of bilateral STAs was performed and mean values of PSV, RI, and PI were calculated. A total of 208 subjects, with a mean age of 37.7 years, underwent Doppler evaluation of STA; 148 of them were women and 60 were men. The mean PSV obtained was 16.94 ± 5.3 cm/s. Mean PI and RI were 0.93 ± 0.31 and 0.5 ± 0.13, respectively. There was no significant difference in the values obtained among both the genders. Mean values of Doppler indices of STA in euthyroid individuals have been found in this study.
[en] The combined determination of β2-M, THP, Alb, IgG may be used as the sensitive indication of the early degeneration of kidney function. The authors observed 107 cases, and found that the anomalous examine-out ratios of hemorrhage β2-M and UTHP are 50.75% and 65.67% respectively, 1.5-2.3 times higher than the Ccr animals examine-out ratio. The radio-immunoassay of β2-M and THP is a better measure for discovering light kidney function injury in early period than Ccr method. The clinical value of the radio-immunoassay of β2-M, THP is obviously better than the traditional and classical method. The diseases of anybody system may influence the kidney function through various mechanisms. The retrogression of kidney tissue of the patients in old-and mid-age leads to decrease of kidney function. The combination of β2-M and THP has the highest anomalous examine-out ratios of kidney function; the next is urine Alb
[en] Ortner's syndrome (left recurrent laryngeal nerve palsy caused by cardiovascular pathology) is described in literature as occurring secondary to a variety of conditions. Spontaneous aneurysm of ductus arteriosus is a rare cause of this condition. We present a case where an adult patient with an aneurysm of the ductus arteriosus presented for the first time at the age of 62 years with hoarseness of voice secondary to left recurrent laryngeal nerve palsy
[en] Paediatric interventional uroradiology lies at the intersection of the disciplines of paediatric interventional radiology and paediatric endourology. Interdisciplinary collaboration has led to the development of new techniques and refinement of procedures adopted from adult practice. This article reviews the major procedures used in paediatric interventional uroradiology, with emphasis on nephrostomy, percutaneous nephrolithotomy, balloon-burst pyeloplasty, and antegrade ureteric stenting.
[en] Position emission tomography (PET) imaging using [18F]-setoperone to quantify cortical 5-HT2A receptors has the potential to inform pharmacological treatments for geriatric depression and dementia. Prior reports indicate a significant normal aging effect on serotonin 5HT2A receptor (5HT2AR) binding potential. The purpose of this study was to assess the test-retest variability of [18F]-setoperone PET with a high resolution scanner (HRRT) for measuring 5HT2AR availability in subjects greater than 60 years old. Methods: Six healthy subjects (age range = 65–78 years) completed two [18F]-setoperone PET scans on two separate occasions 5–16 weeks apart. The average difference in the binding potential (BPND) as measured on the two occasions in the frontal and temporal cortical regions ranged between 2 and 12%, with the lowest intraclass correlation coefficient in anterior cingulate regions. We conclude that the test-retest variability of [18F]-setoperone PET in elderly subjects is comparable to that of [18F]-setoperone and other 5HT2AR radiotracers in younger subject samples
[en] Thirteen patients with varying degrees of Graves' ophthalmopathy were examined using high-resolution infrared oculography to determine peak velocities for horizontal eye movements between 3 degrees and 30 degrees. As severity of the orbital disease increased, peak velocities became substantially lower. Vertical-muscle surgery failed to have any effect on peak velocity of horizontal eye movements. In contrast, orbital decompression caused notable improvement in peak velocity of eye movements. Eye-movement recordings, which provide a measure of extraocular muscle function rather than structure, may provide a safe, sensitive, and accurate method for classifying and following up patients with Graves' ophthalmopathy
[en] Humoral primary immunodeficiency diseases (hPIDs) are a heterogeneous group of hereditary disorders resulting in abnormal susceptibility to infections of the sinopulmonary tract. Some of these conditions (e.g., common variable immunodeficiency disorders [CVID]) imply a number of non-infectious thoracic complications such as non-infectious airway disorders, diffuse lung parenchymal diseases, and neoplasms. Chest high-resolution computed tomography (HRCT) is a key imaging tool to characterise and quantify the extent of underlying thoracic involvement, as well as to direct and monitor treatment. The aims of this review are to provide a brief clinical overview of hPIDs and describe the related chest HRCT imaging features in the adult population, with a special focus on CVID and its complications.
