Ultrasound elastography assessment of skin involvement in systemic sclerosis: Lights and shadows

Objective. To assess skin elasticity in systemic sclerosis (SSc) by using a new imaging modality, ultrasound elastography (UE). Methods. Our study included 18 consecutive patients with SSc and 15 healthy controls. Modified Rodnan skin score, physical examination, and assessment of organ involvement were performed. UE was carried out on the middle forearm and on the fingers of the dominant arm. The echo signals recorded in real time during freehand operations of probe compression and relaxation produced images representing tissue elasticity, consisting of translucent colored bands superimposed on the B-mode ultrasonographic images. The color scale varied within a large band spectrum from red, indicative of soft and highly elastic tissue, to blue, which denoted hard and barely elastic tissue. Results. On the forearm of all patients, UE showed a homogeneous blue area corresponding to the dermis visualized in a B-mode ultrasonographic image; in controls, a blue pattern was never detected and a predominance of green with sporadic areas of pale blue was observed. At sequential evaluations, UE of fingers produced inconstant and changeable colored areas. Conclusion. The imaging pattern observed in the forearm of patients with SSc may represent the reduction of strain in the dermis clue to loss of elasticity. The variable pattern obtained by finger evaluation demonstrated that UE can assess skin involvement in SSc only in those areas where the dermis is known to be thicker and where the bone hyperreflection is minimal. Further studies are needed to confirm our results and determine the validity of this new imaging modality. (First Release June 15 2010; J Rheumatol 2010;37: 1688-91: doi:10.3899/jrheum.090974

Vitamin D and Physical Performance in Elderly Subjects: The Pro.V.A Study

Background The role of Vitamin D in musculoskeletal functionality among elderly people is still controversial. We investigated the association between serum 25-hydroxyvitamin D (25OHD) levels and physical performance in older adults. Methods 2694 community-dwelling elderly women and men from the Progetto Veneto Anziani (Pro.V.A.) were included. Physical performances were assessed by: tandem test, 5 timed chair stands (TCS), gait speed, 6-minute walking (6 mW) distance, handgrip strength, and quadriceps strength. For each test, separate general linear models and loess plots were obtained in both genders, in relation to serum 25OHD concentrations, controlling for several potential confounders. Results Linear associations with 25OHD levels were observed for TCS, gait speed, 6 mW test and handgrip strength, but not for tandem test and quadriceps strength. After adjusting for potential confounders, linear associations with 25OHD levels were still evident for the 6 mW distance in both genders (p = .0002 in women; <.0001 in men), for TCS in women (p = .004) and for gait speed (p = .0006) and handgrip strength (p = .03) in men. In loess analyses, performance in TCS in women, in gait speed and handgrip strength in men and in 6 mW in both genders, improved with increasing levels of 25OHD, with most of the improvements occurring for 25OHD levels from 20 to 100 nmol/L. Conclusion lower 25OHD levels are associated with a worse coordination and weaker strength (TCS) in women, a slower walking time and a lower upper limb strength in men, and a weaker aerobic capacity (6 mW) in both genders. For optimal physical performances, 25OHD concentrations of 100 nmol/L appear to be more advantageous in elderly men and women, and Vitamin D supplementation should be encouraged to maintain their 25OHD levels as high as this threshold

New genetic loci link adipose and insulin biology to body fat distribution.

Body fat distribution is a heritable trait and a well-established predictor of adverse metabolic outcomes, independent of overall adiposity. To increase our understanding of the genetic basis of body fat distribution and its molecular links to cardiometabolic traits, here we conduct genome-wide association meta-analyses of traits related to waist and hip circumferences in up to 224,459 individuals. We identify 49 loci (33 new) associated with waist-to-hip ratio adjusted for body mass index (BMI), and an additional 19 loci newly associated with related waist and hip circumference measures (P < 5 × 10(-8)). In total, 20 of the 49 waist-to-hip ratio adjusted for BMI loci show significant sexual dimorphism, 19 of which display a stronger effect in women. The identified loci were enriched for genes expressed in adipose tissue and for putative regulatory elements in adipocytes. Pathway analyses implicated adipogenesis, angiogenesis, transcriptional regulation and insulin resistance as processes affecting fat distribution, providing insight into potential pathophysiological mechanisms

Congenital Cardiac Defects, Such as Eustachian Valve, May Increase the Risk of Cryptogenic Stroke: A Case Report

Eustachian valve is an embryonic endocardial heart structure; after birth it becomes an embryogenic residue and its persistance in adult life is unusual.The literature reports some cases of association between Eustachian valve and PFO and is known that the prominent Eustachian valve can represent a way facilitating systemic embolism. Several studies also investigated the role of Eustachian valve in the pathophysiology of both migraine and cerebral em-bolism.In addiction is known how Eustachian valve may increase the risk of endocarditis, which mostly affects intravenous drug abusers or those withimplanted medical devices or central venous catheters. The most commonly identified organism is Staphylococcus aureus(approximately 53% of cases).We present a case of a 46-year-old woman with known migraine. She was hos-pitalized in Stroke Unit for a cryptogenic stroke with a right-to -left shunt de-tected with transcranial doppler ultrasound with \u201cbubble test\u201d and a patent foramen ovale with right-to-left shunt with a fenestration of atrial septumand a voluminous Eustachian valve detected with transesophageal echocardiogra-phy; she developed fever with a blood cultures positive for methicillin-resis-tant Staphylococcus aureus(MRSA), even if without evidence of endocarditis vegetations. In summary, the objective of our paper is to present an example of a correlation between the persistence of the Eustachian valve with bothcryptogenetic stroke, possible valve infection and migrain
