Imaging of sarcopenia.
2016
Sarcopenia is currently considered a geriatric syndrome increasing in older people. The consequences of sarcopenia – in terms of impaired mobility, limited self-sufficiency and disability – have been amply demonstrated, increasing the need to develop methods to identify muscle mass loss as early as possible. Although sarcopenia involves a reduction in both muscle mass and function, loss of muscle mass remains the essential criterion for diagnosing this condition in daily practice. Computed tomography and magnetic resonance imaging represent the gold standard for studying body composition, and can identify quantitative and qualitative changes in muscle mass. These techniques are costly, time…
Lymphoscintigraphy with peritumoral injection versus lymphoscintigraphy with subdermal periareolar injection of technetium-labeled human albumin to i…
2014
Background Preoperative lymphoscintigraphy is without doubt a valid method for the detection of the sentinel lymph node (SLN). There has been considerable debate regarding the optimal site for the introduction of the tracer; various sites include peritumoral (PT), periareolar (PA), subdermal, and intradermal injection. Purpose To evaluate retrospectively the lymphoscintigraphic identification rate of peritumoral (PT) injection versus subdermal periareolar (PA) injection in the detection of SLNs in breast cancer. Material and Methods Between October 2002 and December 2011, a cohort of 906 consecutive patients with biopsy proven breast cancer underwent 914 SLN biopsy procedures. A total of 33…
Prevalence of cervical human papillomavirus infection and types among women immigrated to Sicily, Italy.
2009
We determined the prevalence of human papillomavirus (HPV) cervical infection and HPV genotypes among 115 women immigrating to Sicily (Italy), with regard to abnormal cytology and socio-behavioral characteristics in a cross-sectional, observational study. Information was collected with the help of cultural mediators/translators. HPV-DNA was assayed by the INNOLiPA HPV assay and a nested PCR/sequencing method. Sixty (52.2%) women came from sub-Saharan Africa and 55 (47.8%) from Eastern Europe. HPV infection was found in 55 (47.8%) women. The most frequent types were the oncogenic types HPV-16 (7.8%), HPV-18 and 51 (6.0% each), HPV-52 (5.2%), 31, 53, and 68 (4.3% each). Twenty-seven (23.5%) w…
A pigmented papule acting like a playful ghost: dermoscopy of three targetoid hemosiderotic hemangiomas
2018
Targetoid hemosiderotic hemangioma represents an uncommon, distinctive, benign lympho-vascular lesion, with a variable clinical appearance, typically occurs in the lower limbs and trunk. Most patients are in their 20's or 30's. We describe three dermoscopic cases followed by the review of the literature. Dermoscopic images have been collected and have been evaluated for the presence of dermoscopic features. Concerning the review, we researched on pubmed and records were reviewed noting patient age of onset, sex, location, overall size, dermoscopic appearance. The harmonic mean age of patients was 31 years; the female-to-male ratio was 1:1, and the most common locations were lower extremitie…
Treating Cockroach Phobia With Augmented Reality
2009
In vivo exposure is the recommended treatment of choice for specific phobias; however, it demonstrates a high attrition rate and is not effective in all instances. The use of virtual reality (VR) has improved the acceptance of exposure treatments to some individuals. Augmented reality (AR) is a variation of VR wherein the user sees the real world augmented by virtual elements. The present study tests an AR system in the short (posttreatment) and long term (3, 6, and 12 months) for the treatment of cockroach phobia using a multiple baseline design across individuals (with 6 participants). The AR exposure therapy was applied using the "one-session treatment" guidelines developed by Öst, Salko…
Post-reproductive aged women: a lost generation in the cervical cancer screening programme
2020
The aims of the study were to find out why some post-reproductive aged women did not participate in the organised cervical cancer screening programme in Latvia and to clarify factors that would motivate them to take part. A cross-sectional study was carried out between January and July 2017 among female patients in three general practitioner (GP) practices. GP practice nurses used the Latvian national health service database to identify women aged 25–70 who had not participated in the organised programme for the last 3 years. Participants were asked to complete a specially developed questionnaire. The results were then compared between three age groups: 25–34, 35–49 and 50–70 years. Include…
Aortic root dilation in associated with the reduction in capillary density observed at nailfold capillaroscopy in SSc patients
2020
Systemic sclerosis (SSc) is an autoimmune disease characterized by endothelial dysfunction and fibroblasts activation. Microvascular disease may be easily observed by means of nailfold capillaroscopy. Recent evidences emphasized also the involvement of large-medium arteries in SSc, mainly in terms of increased stiffness of the vessel wall. The study aims to measure aortic root diameter in a cohort of SSc patients and to correlate echocardiographic findings with the capillaroscopic pictures. We analyzed the clinical records of 125 consecutive SSc patients (M/F 14/111, mean age 55 ± 12.7 years, median disease duration 11 years) referring in 3 second-level rheumatology centers. All subjects un…
Abscess of the orbit arising 48 h after root canal treatment of a maxillary first molar
2006
Aim To discuss a rare, but severe complication arising following routine root canal treatment. Summary An orbital abscess is reported that occurred following routine root canal treatment. A young, healthy female patient, with no history of chronic paranasal infection had undergone root canal treatment of the right maxillary first molar. On hospital admission, she presented with extensive periorbital swelling and discreet diplopia. Computed tomography imaging identified massive purulent sinusitis and subsequent involvement of the orbit via the inferior and medial orbital wall within 48 h after completion of root canal treatment. Immediate surgical drainage of the maxillary sinus and the or…
Fatigue, Worry, and Fear—Life Events in the Narratives of Women With Fibromyalgia
2012
In this article we explored narrated life stories of 20 women with a long history of fibromyalgia to reach a deeper understanding of how people interpret the causes and consequences of different life events and illness experiences. Based on narrative analysis, we identified three model narratives that illustrate the different life courses of women with fibromyalgia. In addition, we described a counternarrative that questions fibromyalgia as a chronic disease. In this narrative study, we give insights to the invisible symptoms and unheard experiences that are associated with fibromyalgia and to the ongoing discussion on the etiology and maintenance of fibromyalgia.
Numerical approach to problems of gravitational instability of geostructures with advected material boundaries
1998
SUMMARY We present a numerical approach for solving 2-D mantle flow problems where the chemical composition changes abruptly across intermediate boundaries. The method combines a Galerkin-spline technique with a method of integration over regions bounded by advected interfaces to represent discontinuous variations of material parameters. It allows direct approximation of a natural free surface position, instead of a posteriori calculation of topography from the normal stress at the upper free-slip boundary. We formulate a model where a viscous incompressible fluid filling a square box is divided into layers (not necessarily horizontal) by advected boundaries, across which the density and vi…
