Risk factors for prediction of inadequate response to antiresorptives.

Some patients sustain fractures while on antiresorptives. Whether this represents an inadequate response (IR) to treatment or a chance event has not been elucidated. We performed a study to identify which patients are more likely to fracture while on treatment.

Beta-blocker use is associated with fragility fractures in postmenopausal women with coronary heart disease.

Background And Aims: An association between cardiovascular disease and osteoporosis is described. A number of drugs often used by patients with coronary heart disease, such as thiazides, statins and beta-blockers, have shown controversial effects on bone. 1) To study the possible association between coronary heart disease (CHD) and bone mass density (BMD), quantitative ultrasound measurements (QUS) and the prevalence of fragility and vertebral fractures.

Bone mineral density and risk of fractures in aging, obese post-menopausal women with type 2 diabetes. The GIUMO Study.

Background And Aims: Type 2 diabetes mellitus (DM) has a high prevalence in aging obese postmenopausal women. It is not clear whether or not diabetes produces an increase in bone mineral density or an increase in fracture rates.

Objective: The main objective of this study was to investigate whether type 2 DM produces a higher prevalence of vertebral, hip and non-vertebral fractures in obese postmenopausal Caucasian women.

Prevalence of Paget's disease of bone in Spain.

Introduction: Epidemiological studies in Europe have revealed that the prevalence of Paget's disease of bone (PDB) has marked geographic variations. At present, the prevalence of PDB in Spain is unknown, limited to data from isolated towns or centers. We conducted a radiological national-based survey, to estimate the age and sex prevalence of PDB and its geographic variation within the country.

[Adverse cutaneous reactions to erlotinib].

Introduction: Erlotinib is an inhibitor of human epidermal growth factor approved for treating non-small cell lung cancer. The aim of this prospective observational study was to determine the prevalence of adverse cutaneous reactions caused by erlotinib and assess the management of such effects.

Methods: Eleven patients with lung cancer and 1 with ovarian cancer received erlotinib at a dose of 150 mg/d.

Reticular telangiectatic erythema associated with an implantable cardioverter defibrillator.

Reticular telangiectatic erythema (RTE) is a skin reaction associated with implantable cardiac devices (ie, pacemakers and cardioverter defibrillators). We present a patient who developed an erythematous patch over the implantable cardioverter defibrillator site. We discuss the clinical features, histologic findings, and patch testing of this entity.

[Pseudovascular squamous cell carcinoma].

The adenoid form of squamous cell carcinoma is a neoplasm that is characterized by the fact that it presents a pseudoglandular pattern in the histological study. The biological phenomenon that explains this histological pattern is acantholysis; when the latter is massive, the tumor may even mimic a vascular proliferation, and is known as pseudovascular squamous cell carcinoma. This tumor has the clinical characteristics of a squamous cell carcinoma, but histologically, it may mimic an angiosarcoma.

[Stevens-Johnson syndrome and toxic epidermal necrolysis].

Introduction: The aim of this work is to reflect the clinical experience of the Dermatology Department of Hospital General in Valencia with Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) or Lyell's syndrome over the last 15 years.

Methods: Data on epidemiology, likely causal agents, complementary tests, concomitant pathologies, management, evolution and complications was gathered through a retrospective study.

Results: Thirteen patients were included, with a mean age of 53 years.

Inhaled steroids do not decrease bone mineral density but increase risk of fractures: data from the GIUMO Study Group.

Although the negative effect of systemic steroids on bone is well documented, there is not clear evidence about possible adverse effects of inhaled steroids on bone metabolism and fractures. A cross-sectional study was performed on 105 women suffering from bronchial asthma treated with inhaled steroids and 133 controls. Bone mineral density (BMD) was measured by quantitative ultrasonography (QUS) at the calcaneus and by dual X-ray absorptiometry (DXA), at both the lumbar spine and proximal femur.

[Papillary dermal elastolysis similar to pseudoxanthoma elasticum].

Papillary dermal elastolysis similar to pseudoxanthoma elasticum is an elastolytic disorder characterized by cutaneous lesions on the neck and in the supraclavicular region that are clinically similar to pseudoxanthoma elasticum, with no systemic complications. The histological examination shows a loss of elastic fibers in the papillary dermis. We report a case in a 76-year-old woman with typical lesions on the neck.

[Treatment of severe refractory pemphigus vulgaris with rituximab].

Pemphigus vulgaris is a potentially fatal autoimmune bullous disease. High doses of immunosuppressive drugs are used in managing severe cases of pemphigus. Rituximab, an anti-CD20 monoclonal antibody, has proven to be effective in patients with refractory pemphigus vulgaris and pemphigus foliaceus.

[Scleredema of Buschke associated with diabetes mellitus. Study of four cases].

Scleredema of Buschke is characterized by a thickening of the dermis with mucin deposits among the collagen fibers, which manifests as a hardening of the skin, predominantly on the upper trunk. It has been associated with long-standing, poorly controlled diabetes mellitus, monoclonal gammopathies and streptococcus infections. We studied patients with a clinical diagnosis of scleredema confirmed by means of a histopathological study, and associated with diabetes mellitus.

Postmenopausal women with Colles' fracture have bone mineral density values similar to those of controls when measured with calcaneus quantitative ultrasound.

Background: It is a matter of controversy whether or not Colles' fracture is an osteoporotic fracture. Indeed, the usefulness of quantitative ultrasound in distinguishing Colles' fracture from normal fractures is also unclear.

Methods: A cross-sectional case-control study was done on 469 postmenopausal Spanish women, 121 with Colles' fracture and 348 controls.

Postmenopausal women with colles' fracture have lower values of bone mineral density than controls as measured by quantitative ultrasound and densitometry.

Measurement of ultrasonographic parameters provides information concerning not only bone density but also bone architecture. We investigated the usefulness of ultrasonographic parameters and bone mineral density (BMD) to evaluate the probability of Colles' fracture. Two-hundred eighty-nine postmenopausal women (62.

Compliance and satisfaction with raloxifene versus alendronate for the treatment of postmenopausal osteoporosis in clinical practice: An open-label, prospective, nonrandomized, observational study.

Background: The treatment of osteoporosis among postmenopausal women represents a major public health challenge because long-term therapy is needed to prevent fractures and chronic disability. Low patient compliance with prescribed osteoporosis treatments can severely distort the validity of controlled clinical trials. Raloxifene and alendronate have been shown to reduce the incidence of osteoporotic fracture in postmenopausal women in well-conducted randomized trials, but few data are available on the rate of adherence to these treatments in routine clinical practice.

Low vitamin D levels in outpatient postmenopausal women from a rheumatology clinic in Madrid, Spain: their relationship with bone mineral density.

To evaluate a possible relationship between vitamin D levels and bone mineral density (BMD) and the prevalence of hypovitaminosis in a population of postmenopausal women from a rheumatologic outpatient clinic in Madrid, Spain, 171 postmenopausal women (aged 47-66 years) divided into two groups (osteoporotic and nonosteoporotic, according to WHO criteria) were studied between November and June. Liver and kidney function were normal in all subjects. Serum parathyroid hormone (PTH) and calcidiol levels were determined and bone densitometry carried out at the lumbar spine and hip level.

[High prevalence of vitamin D deficiency in postmenopausal women at a rheumatology office in Madrid. Evaluation of 2 vitamin D prescription regimens].

Background: Vitamin D deficiency has been frequently observed in the elderly population in Europe. However few information is available about the vitamin D status in postmenopausal women in the Mediterranean countries. The aim of this study was to evaluate the vitamin D status assessed by serum 25(OH)D3 (calcidiol) in postmenopausal women who attended a Rheumatology practice in Madrid area, and to evaluate calcidiol serum levels through one year after two forms of vitamin D administration.

Pamidronate and biochemical markers of bone turnover.

We have examined the response of different biochemical bone turnover markers to intravenous pamidronate administration (15 mg for 5 days) in 14 patients with Paget's disease, on days 8, 15 and 30 after pamidronate treatment. Urinary parameters of bone resorption, free pyridinolines (Pyr) and hydroxyproline (OHP), as well as serum tartrate-resistant acid phosphatase (TRAP) were measured. Two serum biochemical osteoblastic markers, alkaline phosphatase (AP) and osteocalcin (OC), were also analysed.

Relations between calcidiol serum levels and bone mineral density in postmenopausal women with low bone density.

The relationship between vitamin D and bone density was studied in 150 selected, mature (45-74), postmenopausal women with a lumbar spine Z score below 0. Vitamin D status was evaluated using calcidiol serum levels. Serum calcitriol and parathyroid hormone (PTH) values were also evaluated in some subjects.
