RESUMO

Vertebral fractures are the most prevalent osteoporotic fractures and are paradoxically the most underdiagnosed. While only one-third of patients have acute pain, they can present other associated chronic complications. Vertrebal fractures are associated with the onset of new fractures, both vertebral and nonvertebral. Radiography of the dorsal-lumbar spine is a useful tool for detecting them but depends on the subjective interpretation of the physician conducting the assessment. New techniques, such as vertebral morphometry, have recently demonstrated greater efficacy in detecting v vertebral fractures and are performed concomitantly with bone densitometry. Knowing how to identify vertebral fractures is essential for the secondary prevention of new fractures and improving our patients' quality of life.

RESUMO

BACKGROUND AND OBJECTIVES: Red blood cell (RBC) transfusion may be justified in iron deficiency anaemia (IDA) when an increase in oxygen delivery is needed, as sometimes occurs in subjects with haemoglobin <8·0 mg/dL, serious comorbidities or at risk of cardiovascular instability. Earlier investigations showed that some patients with severe IDA requiring transfusion had lower than expected post-transfusion haemoglobin levels with poorer clinical outcomes than other patients. After hypothesizing that haemoglobin responses to transfusion were different and that the underlying gastrointestinal (GI) disorders causing IDA could be a confounder explaining this association, these responses were analysed in a prospective cohort of IDA adults referred for outpatient GI investigation. MATERIALS AND METHODS: Transfused patients with proven IDA, baseline haemoglobin at referral <9·0 g/dL and no extraintestinal bleeding were eligible. To assess a homogeneous population, only GI disorders known to cause occult bleeding were considered. Haemoglobin increments per 100 mL of RBCs were investigated. RESULTS: In total, 2818 patients were enrolled over 10·5 years. On multivariable regression, diffuse angiodysplasias and GI cancer independently predicted for reduced increments in post-transfusion haemoglobin [adjusted regression coefficients: -0·082 (95% confidence interval, -0·093 to -0·072) and -0·073 (95% confidence interval, -0·081 to -0·066), respectively, P < 0·001 in both]. Haemoglobin responses in the remaining bleeding disorders were adequate and agreed with the principle that one RBC unit increases the haemoglobin an average of 1 g/dL. CONCLUSION: The potential differential impact of GI disorders on changes in haemoglobin levels after RBC transfusion could be useful for transfusing physicians, especially for diagnostic purposes.

RESUMO

AIMS: To assess inappropriate prescribing in older people with diabetes mellitus during the month prior to a hospitalization, using tools on potentially inappropriate medicines (PIMs) and potential prescribing omissions (PPOs) and comparing inappropriate prescribing in patients with without diabetes. METHODS: In an observational, prospective multicentric study, we assessed inappropriate prescribing in 672 patients aged 75 years and older during hospital admission. The Beers, Screening Tool of Older Person's Prescriptions (STOPP) and Screening Tool to Alert Doctors to Right Treatment (START) criteria and Assessing Care of Vulnerable Elders (ACOVE-3) medicine quality indicators were used. We analysed demographic and clinical factors associated with inappropriate prescribing. RESULTS: Of 672 patients, 249 (mean age 82.4 years, 62.9% female) had a diagnosis of diabetes mellitus. The mean number of prescribing drugs per patient with diabetes was 12.6 (4.5) vs. 9.4 (4.3) in patients without diabetes (P < 0.001). Of those patients with diabetes, 74.2% used 10 or more medications; 54.5% of patients with diabetes had at least one Beers-listed PIM, 68.1% had at least one STOPP-listed PIM, 64.6% had at least one START-listed PPO and 62.8% had at least one ACOVE-3-listed PPO. Except for the Beers criteria, these prevalences were significantly higher in patients with diabetes than in those without. After excluding diabetes-related items from these tools, only STOPP-listed PIMs remained significantly higher among patients with diabetes (P = 0.04). CONCLUSIONS: Polypharmacy is common among older patients with diabetes mellitus. Inappropriate prescribing is higher in older patients with diabetes, even when diabetes-related treatment is excluded from the inappropriate prescribing evaluation.

RESUMO

OBJECTIVE: This study aims to identify the risk factors associated with osteoporotic hip fractures in octogenarians and seeks to refine primary prevention strategies for these fractures. MATERIAL AND METHODS: We conducted a case-control study involving individuals aged 79 years and older with hip fractures, comparing them to age- and sex-matched controls without a history of hip fractures. We collected epidemiological, clinical, anthropometric, and analytical factors. We evaluated the presence of osteoporosis using bone densitometry. We defined sarcopenia according the European Working Group on Sarcopenia in Older People criteria (EWGSOP2). RESULTS: Ninety-five patients per group were analyzed, with a mean age of 82 years, of which 74% were women. The multivariate analysis included statistically significant factors found in the univariate analysis (p < 0.05). These factors included the Barthel Index, nutritional assessment using the CONUT tool, folic acid, vitamin D deficiency, presence of previous fractures, loss of visual acuity, bicipital circumference, sarcopenia, and osteoporosis (densitometry in the neck of the femur). The Nutritional state (OR: 0.08 [0.01-0.61]), the folic acid levels (OR 0.32 [0.1-1]), and a loss of visual acuity (OR 33.16 [2.91-377.87]) were the independent risk factors associated with hip fracture. CONCLUSIONS: The assessment of nutritional status in elderly patients, coupled with a comprehensive geriatric assessment, represents easily reproducible and cost-effective tools. These tools can effectively aid in identifying individuals at risk of hip fractures, thereby contributing to more targeted and efficient preventive measures.

RESUMO

OBJECTIVE: To describe patients diagnosed with hematoma of the rectus abdominis (HRA) muscle. MATERIAL AND METHODS: A retrospective analysis of patients diagnosed with HRA over the past 8 years in our center. RESULTS: A total of 17 patients (9 women) with mean age of 73 years were included in the study. In 52% of the cases the HRA was the cause of hospitalization. Anticoagulant therapy was documented in 70%. More than half of patients treated with low molecular weight heparin had renal insufficiency. In the group receiving oral anticoagulants (OA), 86% had INR greater than 4. Paroxysmal cough appeared in 13. The most common presentation was abdominal pain and palpable mass. CT scan sensitivity was superior to that of the ultrasound. The most common location was the lower right. Treatment was conservative in all but one. Two patients died. Mean decrease in hemoglobin was 4.7 g/dl. Average stay was 19 days. CONCLUSIONS: In our center, HRA almost equally affects both genders and appears in older people with excessive anticoagulation and cough. The clinical presentation, increased diagnostic sensitivity of CT scan and predominance in the right abdominal involvement are similar to other series. Mortality and hospital stay are higher than described.

RESUMO

This paper presents the first experience of the Spanish Society of Internal Medicine in the development of an Internet-based Continuing Medical Education program for Society members, accredited by the Health Ministry and the Autonomous University of Barcelona, and funded by the Menarini Group SA. Academic performance and satisfaction of participants in this course have been very satisfactory, both with respect to scientific content and the virtual learning environment. This experience shows that Internet-based continuing medical education is a field with a great future that is well accepted by participating physicians, and that the scientific societies, with the collaboration of other institutions and companies, can lead Internet-based Continuing Medical Education programs especially designed and tailored to their members.

RESUMO

OBJECTIVES: To evaluate the characteristics associated with falls causing hip fracture in patients 90 years of age or older (nonagenarians). A second objective was to compare these characteristics with those present in younger patients (65-79 year-olds). DESIGN: Prospective, observational study. SETTING: Six hospitals in Barcelona (Spain) and its surrounding area. PARTICIPANTS: 105 nonagenarians diagnosed with hip fracture after a fall. Most patients were women (78; 74%), with a mean age of 92.2+/-2 years. All of them were living in the community, except for eight institutionalized patients. 221 patients aged 65 to 79 composed the younger patient's comparison group. MEASUREMENTS: Characteristics of falls causing hip fracture were analyzed: location, time and the risk factor for the fall, classified as intrinsic, extrinsic or combined. RESULTS: The mean number of falls in the previous year was 1.5 - 22% of the patients reported having fallen two or more times. Falls usually happened while at home (70%) and during the day (64%). An intrinsic risk factor was considered the most likely cause in 37% of the cases, an extrinsic risk factor in 35%, and a combination in 28%. Multiple stepwise logistic regression analysis showed that nonagenarians were characterized by lower BI scores, more falls happening during night time, a higher use of, benzodiazepines and diuretics, and a lower use of non-benzodiazepinic hypnotics. CONCLUSIONS: Most falls causing hip fracture in nonagenarians happen during the day and at home. Falls in nonagenarians happening more frequently during nighttime, and these oldest subjects had lower BI scores, and a higher use of benzodiazepines and diuretics and less use of non-benzodiazepines hypnotics compared with the younger patients.

RESUMO

OBJECTIVES: The European Working Group on Sarcopenia in Older People (EWGSOP) has proposed different methods and cut-off points for the three parameters that define sarcopenia: muscle mass, muscle strength and physical performance. Although this facilitates clinical practice, it limits comparability between studies and leads to wide differences in published prevalence rates. The aim of this study was to assess how changes in cut-off points for muscle mass, gait speed and grip strength affected sarcopenia prevalence according to EWGSOP criteria. METHODS: Cross-sectional analysis of elderly individuals recruited from outpatient clinics (n=298) and nursing homes (n=276). We measured muscle mass, grip strength and gait speed and assessed how changes in cut-off points changed sarcopenia prevalence in both populations. RESULTS: An increase from 5.45 kg/m2 to 6.68 kg/m2 in the muscle mass index for female outpatients and nursing-home residents increased sarcopenia prevalence from 4% to 23% and from 9% to 47%, respectively; for men, for an increase from 7.25 kg/m2 to 8.87 kg/m2, the corresponding increases were from 1% to 22% and from 6% to 41%, respectively. Changes in gait speed and grip strength had a limited impact on sarcopenia prevalence. CONCLUSION: The cut-off points used for muscle mass affect the reported prevalence rates for sarcopenia and, in turn, affect comparability between studies. The main factors influencing the magnitude of the change are muscle mass index distribution in the population and the absolute value of the cut-off points: the same difference between two references (e.g., 7.5 kg/m2 to 7.75 kg/m2 or 7.75 kg/m2 to 8 kg/m2) may produce different changes in prevalence. Changes in cut-off points for gait speed and grip strength had a limited impact on sarcopenia prevalence and on study comparability.

RESUMO

OBJECTIVES: To analyse the characteristics of the hospitalized very elderly people (age equal or superior to 80 years) with hypertension (HT). PATIENTS AND METHODS: Prospective study including the patients with HT who need hospitalization in our medical institution. Data collected were: demographic, clinical parameters, factors of vascular risk, hygienic-dietetic strategies, pharmacological treatment, cause of hospitalization, and biochemical determinations. RESULTS: There were included 92 very elderly patients (71 women); they represent 14 % of total hospitalized people. Two third parts had not realized academic studies, being 60 % of rural origin. Almost the half (41 %) was diabetic, and 27 % had dyslipidemia. Overall 62 % had 4 or more factors of cardiovascular risk. The hospitalization was related to the HT in the half of the cases, and 61 % had already previously some cardiovascular event. The lifestyle modifications more frequent were: not to smoke (95 %), no alcohol (81 %), and diet without salt (75 %). Diuretics were the most frequent anti-hypertensive agent used. The global mortality was two times superior to the hypertensive population < 80 years in the same period. CONCLUSIONS: The very elderly hypertensive patients of our study are fundamentally women, of rural origin and without academic studies. The above mentioned hospitalization is attributable directly to the HT in the half of the cases. They are a population of high cardiovascular risk, with previous events cardiac and cerebral-vascular. They confess to realize frequently the hygienic-dietetic strategies recommended. The diuretics are the anti-hypertensive agents most used for the HT. Since it was of waiting for the mortality in this group it is high.

RESUMO

This report describes a rare case of intra-abdominal liposarcoma in a 67-year-old woman. The patient presented at Internal Medicine Unit in May 2004, to study of thyroid pathology. The clinical examination was normal, except for the finding of an asymptomatic mass in the abdomen. The patient knew the existence of tumor since time ago, but she confesses to have only occasional discomfort. In the abdominal ultrasonography a solid mass with large cystic component was detected but relation with other organs was not clear. Computed tomography revealed the presence of a mass with solid and cystic components, in contact with small intestine in the left side of abdomen. A complete resection of tumor arising from mesentery of jejunum was performed successfully with end to end anastomosis. The gross specimen was lobulated and measured 8.5 x 7.5 cm. The histopathology analysis showed proliferating lipoblasts with irregular nuclei on a myxoid background, with plexiform vascular pattern, characteristics belongs to myxoid type liposarcoma. The patient is alive and well one year after removal of tumor. The uncommon site and the exceptional cystic morphology of tumor are discussed, and so it must be included the primary mesenteric liposarcoma in the differential diagnosis of intra-abdominal tumors with cystic large areas.

RESUMO

PURPOSE: To determine whether the features of the antiphospholipid syndrome (APS) are in any way influenced by the presence or absence of systemic lupus erythematosus (SLE). We followed up patients with 'primary' APS (PAPS) and APS secondary to SLE (APS plus SLE) with the objective of comparing laboratory and clinical events and of determining whether patients with PAPS would have evolution to SLE. PATIENTS AND METHODS: A total of 114 patients from 3 European referral centers were included in this study. Fifty-six had APS plus SLE and 58 had PAPS. Laboratory and clinical data were collected during an average 2-year period. RESULTS: Patients with PAPS and patients with APS plus SLE had similar clinical and laboratory profiles, with the exceptions of autoimmune hemolytic anemia, endocardial valve disease, neutropenia, and low C4 levels, all of which occurred more frequently in patients with APS plus SLE (p values: < 0.05, < 0.005, < 0.01, and < 0.001, respectively). On follow-up, 10 thrombotic episodes occurred in 10 patients, 8 of whom were receiving anticoagulant therapy. No patient with PAPS had either anti-DNA or anti-extractable nuclear antigen antibodies, and these patients had a significantly lower prevalence of antinuclear antibodies (41%) than patients with APS plus SLE (89%). CONCLUSIONS: Patients with APS plus SLE and PAPS have similar clinical profiles, although heart valve disease, hemolytic anemia, low C4 levels, and neutropenia seem to be more common in patients with APS plus SLE. Patients with APS may develop further thrombotic events despite anticoagulation therapy.

RESUMO

The effect on platelet function of plasma from 9 patients with primary antiphospholipid syndrome (PAS) with previous thrombotic episodes was investigated under flow conditions. Five asymptomatic individuals with antiphospholipid antibodies (aPL) (A-aPL) and 14 normal controls were also studied. Patients and controls plasmas were added (1:20 v/v) to anticoagulated blood and perfused through annular chambers containing collagen rich vessel segments. The interaction of platelets with vessel subendothelium was morphometrically evaluated in thin sections. An increase in both covered surface and thrombi formation was observed in perfusions in the presence of PAS-plasma (mean +/- SD: 34.2% +/- 9.6% and 23.2% +/- 10.0% respectively) compared with control plasmas (21.4% +/- 7.3% and 10.1% +/- 7.7%, p < 0.01). Affinity purified anticardiolipin antibodies from one PAS patient showed a similar effect when added to normal blood. In contrast, A-aPL plasma had no effect on platelet-subendothelium interaction. In parallel studies, the same plasmas were incubated with isolated normal platelets before and after activation with ADP or collagen and the binding of immunoglobulins (Ig) was determined by flow cytometry. A significantly increased binding of Ig was observed in 8 out of 9 plasmas from PAS patients when platelets had been activated with collagen but not when resting or ADP activated platelets were used. No increased Ig binding to platelets was seen using A-aPL individuals plasma. These observations might help to explain the pathophysiology of the thrombotic events occurring in patients with PAS.

RESUMO

Hypercalcemia may occur during the course of various granuloma-forming diseases. Herein we describe a patient who had symptomatic hypercalcemia as a prominent sign of Wegener's granulomatosis. We observed a direct correlation between the serum levels of 1,25-dihydroxyvitamin D [1,25(OH)2D] and both the serum and the urinary calcium levels. Administration of prednisone and cyclophosphamide led to a substantial decrease in the levels of calcium and serum 1,25(OH)2D, but the serum levels of 25-hydroxyvitamin D remained unchanged. Two months after admission of the patient, the levels of calcium and 1,25(OH)2D increased; after we increased the dose of cyclophosphamide, these levels decreased (the dose of corticosteroids was not changed). We suggest that the excessive synthesis of 1,25(OH)2D was inhibited by a direct or indirect action not only of prednisone but also of cyclophosphamide on the 1 alpha-hydroxylation of 25-hydroxyvitamin D in the activated macrophage of Wegener granulomas. Furthermore, in view of this case and two other recently reported cases, we believe that Wegener's granulomatosis must be definitively added to the list of granulomatous diseases that are responsible for 1,25(OH)2D-mediated hypercalcemia.

RESUMO

OBJECTIVES: To study the clinical characteristics at diagnosis and during follow-up of patients with the antiphospholipid syndrome (APS) and to analyze the influence of treatment on their outcome. PATIENTS: One hundred patients with APS were included (86% female and 14% male; mean age, 36 years). Sixty-two percent had primary APS and 38% had APS associated with systemic lupus erythematosus (SLE). The median length of follow-up was 49 months. RESULTS: Fifty-three percent of the patients had thromboses, 52% had thrombocytopenia, and 60% of the women had pregnancy losses. Patients with APS associated with SLE had a higher prevalence of hemolytic anemia (P = .02), thrombocytopenia (platelet count lower than 100 x 10(9)/L) (P = .004), antinuclear antibodies (P = .0002), and low complement levels. Fifty-three percent of the patients with thrombosis had recurrent episodes (86% in the same site as the previous thrombotic event). Recurrences were observed in 19% of the episodes treated with long-term oral anticoagulation, in 42% treated prophylactically with aspirin, and in 91% in which anticoagulant/antiaggregant treatment was discontinued (P = .0007). Multivariate analysis showed that prophylactic treatment and older age had an independent predictive value for rethrombosis. Prophylactic treatment during pregnancy (usually with aspirin) increased the live birth rate from 38% to 72% (P = .0002). CONCLUSIONS: Patients with APS have a high risk of recurrent thromboses. Long-term oral anticoagulation seems to be the best prophylactic treatment to prevent recurrences. Prophylactic treatment with aspirin during pregnancy reduced the rate of miscarriages remarkably.

RESUMO

Antiendothelial cell antibodies (AECA) have been detected in 20 out of 30 patients (67%) with thrombosis associated with antiphospholipid antibodies. Seven patients had systemic lupus erythematosus and 13 had the "primary" antiphospholipid syndrome. Seven patients had both IgG and IgM AECA, 9 had IgG AECA only, and 4 had only IgM AECA. None of 30 control patients with thrombotic events not related to antiphospholipid antibodies had a positive titre of AECA (P less than 0.001). No correlation between AECA, antinuclear antibodies, anti-dsDNA antibodies, anti-neutrophil cytoplasm antibodies, precipitating antibodies to soluble nuclear and cytoplasmic antigens or complement components was found. The possible role of these AECA in the pathogenesis of thrombotic events is discussed.

RESUMO

Twenty-three patients with the 'primary' antiphospholipid syndrome were studied over 2-6 years. Twenty-two (96%) had antiphospholipid antibodies detected by ELISA (87% had antibodies to thromboplastin and 70% to cardiolipin), and 18 out of the 21 tested patients (86%) had lupus anticoagulant activity by coagulative assays. Mean age of the cohort was 29.9 years and the sex ratio (female:male) 4.75:1. Eleven patients presented 18 venous and/or arterial thrombosis and 13 had 25 foetal losses (84% occurred during the second and third trimester). Other clinical features were migraine, livedo reticularis, and epilepsy. Three patients had relatives with systemic lupus erythematosus. Thrombocytopaenia was seen in 33%, antinuclear antibodies in low or moderate titre in 30%, and haemolytic anaemia in 13%. During the follow-up, two patients presented recurrent thrombosis despite anticoagulant therapy, one of them dying because of recurrent pulmonary thromboembolism. Four patients achieved successful term pregnancies after treatment with aspirin and a further patient after treatment with aspirin and low dose prednisolone. No patient developed systemic lupus erythematosus or any other definable connective tissue disease. The 'primary' antiphospholipid syndrome may exist as a distinct clinical entity and all younger patients presenting with thrombotic events, foetal losses and/or thrombocytopaenia, without any evidence of a well defined disease, should be tested for antiphospholipid antibodies in order to rule out this syndrome.

RESUMO

We determined the prevalence and relationship with clinical manifestations of antibodies to thromboplastin (aTP) in 92 patients with systemic lupus erythematosus (SLE). Thirty-two (35%) patients had aTP: 13 (14%) were positive for IgG aTP, 13 (14%) for IgM aTP, and 6 (7%) for both. Patients with aTP had an increased incidence of thrombosis (p = 0.01), thrombocytopenia (p < 0.001), hemolytic anemia (p < 0.001), and fetal losses (p = 0.03). When the IgG and IgM aTP isotypes were analysed separately, the IgG aTP were found to be associated with thrombosis (p < 0.001), thrombocytopenia (p < 0.001), and fetal losses (p = 0.02). The IgM aTP were associated with hemolytic anemia (p < 0.001). A correlation was found between the titers of aTP and those of anticardiolipin antibodies, in both IgG (p < 0.01, r = 0.6) and IgM (p < 0.01, r = 0.64) isotypes, and between the titers of IgG aTP and the diluted Russell's viper venom time used to detect the lupus anticoagulant (p < 0.001, r = 0.42). This test is a reliable, reproducible and sensitive assay for the detection of antiphospholipid antibodies, specially in those patients under anticoagulant therapy.

RESUMO

IgG and IgM isotypes of anticardiolipin (aCL) antibodies were measured in a group of 40 patients with biopsy-proven temporal arteritis (TA), 13 of them with ischemic complications related to the disease. High levels of aCL antibodies were found in only 3 (7.5%) patients. Two had high titres of both IgG and IgM isotypes and the third had high titres of the IgM isotype. No relationship between aCL antibody positivity and the development of any of the classical early occlusive complications of TA was found. However, 2 out of the 3 patients with positive aCL antibody titres later developed ischemic phenomena on conventional corticosteroid treatment. This finding suggests that aCL antibodies could perhaps have a role in the development of the late ischemic complications that occasionally occur in adequately treated TA patients.
