Abstract:

Conventional assessment of overactive bladder syndrome uses invasive pressure-measuring catheters to detect bladder contractions (urodynamics). We hypothesised that bladder shape changes detected and measured using transabdominal ultrasound scan could provide a non-invasive and clinically useful alternative investigation of bladder contractions. This feasibility study evaluated a novel transabdominal ultrasound scan bladder shape test during conventional urodynamics and physiological bladder filling. The aim was to initially evaluate and refine a non-invasive approach for detecting and quantif

Objective: Infertility affects approximately 10–15% of couples. Assessment of the endometrium with ultrasound has become a standard procedure during the diagnostic workup and treatment of infertility. Our study was designed to investigate whether endometrial thickness on the day of human chorionic gonadotropin administration is a predictor of intrauterine insemination (IUI) success as the primary outcome. Materials and Methods: In the prospective observational study, a serial transvaginal ultrasound scan was performed to measure endometrial thickness following ovulation induction with clomiphe

Purpose: To assess serial CT as a measure of the progress of emphysema in patients with severe α1,-antitrpsin deficiency (phenotype PiZ). Material and Methods: In a randomized placebo-controlled study of α1,-antitrypsin augmentation therapy, 22 patients with moderate emphysema were followed for 2–4 years with an annual lung CT. The images were analysed by means of semiautomatic lung detection, and the degree of emphysema was quantitated by the density-mask and the percentile methods. The influence of lung volume was standardised by a regression model. Results: A highly significant decline in H

This analysis aimed to evaluate the association of AP/ELP with cardiovascular events.

Abstract:

Abstract Autoimmune Lymphoproliferative Syndrome (ALPS) is a disorder of abnormal lymphocyte survival caused by defective Fas-mediated apoptosis. Patients with ALPS develop lymphadenopathy, hepatosplenomegaly, and an increased number of an unusual T cell population, characterized as T cells that are CD3+ CD4− CD8− and referred to as double negative T cells (DNTs). Although ALPS is a rare disorder, we have shown it may be more common than previously appreciated. Treatment options for patients with ALPS are limited.

Background: IUGR refers to a condition in which a fetus is unable to grow to its genetically predetermined potential size. It is the major cause of perinatal morbidity and mortality in developing countries. The present study was conducted to compare the validity of clinical diagnosis against sonographic diagnosis of IUGR.Methods: This study was conducted in the department of Obstetrics and Gynaecology, SMGS Hospital, Jammu from Octobar 2013 to September 2014. It included 247 women with singleton pregnancies with longitudinal lie. They underwent serial clinical assessment using SFH, AG and weig

Abstract:

Real-time elastosonography (RTE) is a recently described, non-invasive, ultrasonographic technique developed to assess tissue elasticity. The main aim of this study was to investigate the ultrasonographic and elastosonographic appearance of the common calcaneal tendon (CCT) in an ovine model, and to monitor the progression of tendon healing after an experimentally-induced tendinopathy. Sound tendons were initially evaluated (T0) with a caliper and by a single operator with ultrasound. Ultrasonographic and elastosonographic images were then acquired. Subsequently, ultrasound-guided tendon lesio

Objectives: To evaluate trends of nasal bone length (NBL), prenasal thickness (PT), nuchal fold (NF), prenasal thickness to nasal bone length (PT-NBL) ratio, and prefrontal space ratio (PFSR), measured serially in second- and third-trimester Down syndrome (DS) fetuses. Methods: Prenatal databases were searched for cases of continuing DS pregnancies with serial measurements, taken at least two weeks apart. Trends were plotted on previously reported normal ranges. Results: Serial measurements were available in 25 Down syndrome fetuses. Median gestational age (GA) was 25 weeks; average number of

Abstract:

Muscle damage is a common response to unaccustomed eccentric exercise; however, the effects of skeletal muscle damage on local vascular function and blood flow are poorly understood. This study examined serial local vascular responses to flow-mediated (endothelial-dependent) and nitroglycerin-mediated (endothelial-independent) dilation in the brachial artery after strenuous eccentric exercise and serially assessed resting blood flow. Ten healthy males performed 50 maximal eccentric unilateral arm contractions to induce muscle damage to the biceps brachii. Changes in maximal isometric strength

Abstract:

In mice, myocardial hypertrophic preconditioning (HP), which is produced by the removal of short-term transverse aortic constriction (TAC), was recently reported to render the heart resistant to hypertrophic responses induced by subsequent reconstriction (Re-TAC). However, there is no efficient noninvasive method for ensuring that the repeated aortic manipulations were successfully performed. We previously demonstrated that ultrasound biomicroscopy (UBM) is a noninvasive and effective approach for predicting TAC success. Here, we investigated the value of UBM for serial predictions of load con

Objective. Hourly fetal urine production rate (HFUPR) was studied in relation to both gestational age and the onset of spontaneous labor in normal term human pregnancies. Methods. Serial volume measurements were obtained from longitudinal ultrasound images of the fetal bladder at 1–5-minute intervals, and HFUPR was subsequently calculated. A total of 178 adequate bladder-filling cycles were recorded in 112 women, and the amniotic fluid index (AFI) was assessed. Results. HFUPR did not change significantly between 37 and 42 weeks' gestation. However, HFUPR decreased during the last 14 days prior

Abstract:

AbstractDespite decades of research, the mortality rate of sepsis and septic shock remains unacceptably high. Delays in diagnosis, identification of an infectious source, and the challenge of providing patient-tailored resuscitation measures routinely result in suboptimal patient outcomes. Bedside ultrasound improves a clinician's ability to both diagnose and manage the patient with sepsis. Indeed, multiple point-of-care ultrasound (POCUS) protocols have been developed to evaluate and treat various subsets of critically ill patients. These protocols mostly target patients with undifferentiated

Abstract:

Many women in resource-poor settings lack access to reliable gestational age assessment because they do not know their last menstrual period; there is no ultrasound (US) and methods of newborn gestational age dating are not practised by birth attendants. A bespoke multiple-measures model was developed to predict the expected date of delivery determined by US. The results are compared with both a linear and a nonlinear model. Prospectively collected early US and serial symphysis-pubis fundal height (SFH) data were used in the models. The data were collected from Karen and Burmese women attendin

Purpose The implantation of abdominal aortic endografts requires the insertion of large devices that have the potential to traumatize the iliac arteries, particularly on the ipsilateral side, where the main body of the endograft is introduced. The consequences of this potential trauma are unknown, but the possibility for significant injury remains. For this reason, a prospective measurement of iliac intimal medial thickness by serial duplex ultrasound was undertaken to determine the effect of endograft placement on iliac arteries.

Nearly all the size distributions 2 to 3 min air, measured with the graded wire screen samplers were unimodal, with a geometric standard deviation averaging 1.8±0.058. The grand average of the geometric mean and standard error of the mean diffusion coefficient was 0.048±0.0004. The results obtained using different combinations of the graded wire screens were consistent. The measured diffusion coefficient predicts a nasal penetration of 9% to 16% for inspiratory
