Risk factors for clinical stress fractures in male military recruits: A prospective cohort study
2004
This prospective study was aimed at evaluating risk factors for symptomatic stress fractures among 179 Finnish male military recruits, aged 18 to 20 years. The subjects were studied in the very beginning of the military service of 6 to 12 months in summer. Bone mineral content (BMC) and density (BMD) were measured by dual energy X-ray absorptiometry (DXA) at the lumbar spine and at the hip and heel ultrasound investigation was performed. Blood was sampled for determination of serum total and free testosterone, total and free estradiol, sex hormone-binding globulin (SHBG), procollagen type I N propeptide, total and carboxylated osteocalcin, tartrate-resistant acid phosphatase 5b, 25-hydroxyv…
Exercise loading history and femoral neck strength in a sideways fall: A three-dimensional finite element modeling study
2016
Over 90% of hip fractures are caused by falls. Due to a fall-induced impact on the greater trochanter, the posterior part of the thin superolateral cortex of the femoral neck is known to experience the highest stress, making it a fracture-prone region. Cortical geometry of the proximal femur, in turn, reflects a mechanically appropriate form with respect to habitual exercise loading. In this finite element (FE) modeling study, we investigated whether specific exercise loading history is associated with femoral neck structural strength and estimated fall-induced stresses along the femoral neck. One hundred and eleven three-dimensional (3D) proximal femur FE models for a sideways falling situ…
Intratumoral Haemorrhage Causing an Unusual Clinical Presentation of a Vestibular Schwannoma
2012
We present a case of an elderly woman with no history of audiological disease with sudden onset of visual and hearing deficits associated with systemic clinical signs. On examination she had impairment of right CNs from V to X. CT and MR imaging demonstrated a cystic vestibular schwannoma with a rare intralesional fluid-fluid level correlated to a recent bleed. We include high quality MR images to show the acute impairment of the cranial nerves next to the tumour after acute bleeding. Our case report includes a voxel-based morphometry (VMB) analysis of the tumour that, as far as we know, has never been done before for such a tumour. VBM analysis was performed to calculate the hypothesized …
Humoral immune response to rotavirus NSP4 enterotoxin in Spanish children.
2005
The rotavirus non-structural protein 4 (NSP4) has been shown to play a crucial role in rotavirus-induced diarrhea, acting as a viral enterotoxin. It has also been demonstrated that antibody to NSP4 can reduce the severity of rotavirus-induced diarrhea in newborn mice. Two recombinant baculoviruses, expressing the NSP4 protein from the SA11 and Wa rotavirus strains, genotypes A and B, respectively, were used to produce and purify these glycoproteins, which were applied as antigen in an enzyme-linked immunosorbent assay (ELISA) to test the specific antibody response to NSP4 in human sera. Serum samples from 30 children convalescing from a rotavirus infection, from 54 healthy children under 5-…
Nephrolithiasis, bone mineral density, osteoporosis, and fractures: a systematic review and comparative meta-analysis
2016
Summary: Our meta-analysis demonstrates that people with nephrolithiasis have decreased bone mineral density, an increased odds of osteoporosis, and potentially an elevated risk of fractures. Introduction: People with nephrolithiasis might be at risk of reduced bone mineral density (BMD) and fractures, but the data is equivocal. We conducted a meta-analysis to investigate if patients with nephrolithiasis have worse bone health outcomes (BMD), osteoporosis, and fractures versus healthy controls (HCs). Methods: Two investigators searched major databases for articles reporting BMD (expressed as g/cm2 or a T- or Z-score), osteoporosis or fractures in a sample of people with nephrolithiasis, and…
The internal calcar septum and its contact with the virtual stem in THR: a computer tomographic evaluation.
2003
The internal calcar septum is a ridge of cortical bone protruding from the inner cortical wall of the proximal femur into the medullary canal. It extends from the lesser trochanter into the femoral neck and narrows the femoral cavity in its dorsal third. This region is essential for THR stability, but the degree of contact between the septum and standard THR implants has never been studied. We obtained CT scans of 50 arthrotic hip joints from patients requiring THR. Virtual stems (50 straight/wedge-shaped and 50 anatomic stems) were placed in CT images of the femora using a PC-based preoperative planning unit. The dimensions of the septum, degree and location of contact between the septum a…
Hypogonadism and Hormone Replacement Therapy on Bone Mass of Adult Women with Thalassemia Major
2002
We studied bone mass and metabolism in 30 adult women (age 28.5 +/- 1.3) with thalassemia major (TM) and evaluated whether prolonged hormone replacement therapy (HRT) was able to optimize bone accrual. TM patients had reduced bone mass, increased bone turnover and lower serum gonadotropin and estradiol levels compared with 10 normal women of similar age. A significant correlation was found between bone mass and sex hormone levels. Six TM patients with normal ovarian function had normal bone turnover markers and modestly low bone mass (lumbar spine -1.29 +/- 0.31; femoral neck -0.60+/-0.21; Z-score). The other 24 TM women were hypogonadic and had significantly lower bone mass for age (lumbar…
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…
Transgresión moral y enfermedad en los países nórdicos en la temprana Edad Moderna
2009
This article seeks to understand how people in the early modern age interpreted the nature of illness and the role that morality played in these interpretations. From this point of view illnesses were not only psycho-physical states or subjects for medical diagnosis but they were also subjects for narratives or stories through which people tried to understand what had caused their illness, and why it was happening to them. Illnesses were understood as strictly connected with the patient's character and were regarded as possible consequences of his personality. On the other hand, the interpretations also emphasised the ambivalence of a healer. Personal experiences and an understanding of one…
Feelings or cognitions? Moral cognitions and emotions as longitudinal predictors of prosocial and aggressive behaviors
2010
Abstract There is debate regarding the roles of sociomoral cognitions and emotions in understanding moral development. The short-term longitudinal relations among perspective taking, sympathy, prosocial moral reasoning, prosocial behaviors and aggression in adolescents were examined. Participants were 489 students ( M age = 12.28 years, SD = .48; 232 boys) in public and private schools from predominantly middle class families in Valencia, Spain. Students completed measures of perspective taking, sympathy, prosocial moral reasoning, prosocial behaviors, and aggressive behaviors. Overall, structural equation modeling analyses showed that moral reasoning and emotions were interrelated and pre…
