Implementation of clinical practice guidelines for acute ischaemic stroke in specialist care centres.

INTRODUCTION: Cerebrovascular disease is associated with high morbidity and mortality. In 2008, the Spanish Ministry of Health published its Clinical Practice Guidelines for stroke prevention, but implementation of that document has not yet been assessed. Our study aims to investigate compliance with the Guidelines by analysing control over vascular risk factors, antithrombotic treatment and lipid lowering treatment in patients who had suffered an acute ischaemic stroke and who were under the care of neurologists or internists. METHODS: Cross-sectional study based on data from clinical reports (vascular risk factors, diagnosis and treatment), blood pressure readings and laboratory tests pertaining to 203 patients diagnosed with acute ischaemic stroke and admitted to a medium-to-long stay hospital for rehabilitation and care. RESULTS: The mean patient age was 75 ± 10 years; 56% were women. The most common risk factors were hypertension (68%) and diabetes mellitus (40%). Intravenous fibrinolytic therapy had been administered to 8.9% of the patients. Of the patients with thrombotic cerebral infarction, 91.7% received antiplatelet agents; 59.4% of patients with embolic infarction received anticoagulants. Statins were prescribed to 65% of patients with thrombotic infarction. Laboratory tests upon admission showed that 23% of patients had total cholesterol levels above 175 mg/dl and 26.6% had plasma glucose levels above 126 mg/dl. Of the patient total, 70% received antihypertensive therapy, but 47.5% had blood pressure levels above 130/80 mm Hg. CONCLUSIONS: In our opinion, secondary prevention of acute cerebrovascular disease could be improved, mainly by increasing the percentage of patients treated with antiplatelet or anticoagulant drugs (depending on aetiology), increasing prescription of statins, and improving blood pressure control.

[Internet application for medical purposes in chronic patients cared in a systemic autoimmune diseases unit]. / Utilización de Internet como fuente de información por los pacientes de una consulta de Enfermedades Autoinmunes Sistémicas.

OBJECTIVE: In recent years Internet has become an important tool for medical information search, not only for physicians but also for the patients. Little is known about Internet patient's use in Spain. Our objective was to study the frequency with which patients with different chronic autoimmune diseases cared in our unit use Internet as a source of medical information, and to identify the factors associated with its use. METHODS: A survey was carried out on Internet use to patients cared in a teaching hospital Systemic Autoimmune Diseases unit along three consecutive weeks. RESULTS: Hundred thirty-eight patients completed the questionnaire. Eighty-seven (63%) were women. Fifty-four patients (39.1%) were older than 55 years. Mean disease progression was 34.2 +/- 39.2 months. 22% of the respondents were uneducated, 39% had elementary education level; 20% had average education level, and 20% had advanced education level. Forty-two patients (30.4%) used regularly Internet for any purpose. Factors associated to Internet use for medical purposes were regular Internet use (OR: 4.6; CI: 1.1-18.8;p = 0.03), and average or advanced educational degree (advanced education: OR: 22.9; CI: 2.6-202.7; p = 0.005; average education: OR: 8.5; CI: 1.2-59.6; p = 0.03). Eighty-one patients (58.7%) expressed their need of information on quality web pages. CONCLUSIONS: Many patients use Internet for medical purposes in our environment and even more consider to use it in the future. It is important to be aware of this fact and facilitate information about quality web pages for interested patients.

[Prescription of generic pharmaceutic specialties in discharge reports at a university hospital]. / Prescripción de especialidades farmacéuticas genéricas en informes de alta de un hospital universitario.

BACKGROUND: The use of generic pharmaceutic specialities (GPS) has risen lately as a necessary tool in the control of sanitary expenses. This use is becoming of high importance, even in the non-medical media. Our aim was to stablish its use profile in patients discharged from a University Hospital. MATERIAL AND METHOD: To analyse the use of GPS in 256 discharge reports, randomly chosen from the Clinical Documentation Service, belonging to eight different Units for two months (June-July 2000). RESULTS: A total of 1233 prescriptions were reported. Among them, there was an equivalent generic drug to the medication prescribed in 220 cases (18%), but only in five ocasions one of them was indicated (2.2%). The cost of the drugs with an equivalent form in GPS was calculated in 707,521 pts. This cost could have been reduced to 505,865 pts. taking into account the average price of the GPS. In case of indicating the cheapest one, the cost could have been 479,672 pts. CONCLUSIONS: There is an important proportion of GPS to indicate as an alternative to the usual medicaments prescribed. However, nowadays, the GPS prescription is not a usual practice among the hospital physicians.

[Usefulness of hepatic biopsy in an internal medicine service]. / Utilidad de la biopsia hepática en un servicio de Medicina Interna.

OBJECTIVES: Study the percentage of clinical successes which have been confirmed by percutaneous hepatic biopsy guided by echography (PHBE) in those diseases which can affect the liver in an Internal Medicine service. PATIENTS AND METHODS: 78 patients were chosen for this study. All of them were admitted to hospital during the last eight years. Each patient had had a PHBE made regarding clinical, analytical and echographic criteria that were necessary to conclude their diagnostic studies. They were distributed into different groups. RESULTS: Patients could be distributed into five different groups. There was a higher percentage of clinical successes on those who suffered from chronic hepatopathy derived from alcohol-addiction and on those with carcinomatous hepatopathies. When corroborating the diagnosis of clinical suspect, the diagnostic profitability of the biopsy proved to get down in the others groups, depending on it was the group of miscellaneous, dissociate cholestasis and, in the last place, unknownly originated fever. CONCLUSIONS: The diversity of diseases which can affect the liver in an Internal Medicine service gives PHBE a particular diagnostic character. The diagnosis of clinical suspect was confirmed in 78.2% of the total of cases that made up the different groups. Therefore, PHBE plays a main role in a large amount of hepatic repercussive diseases that are treated in Internal Medicine services where, despite the clinical suspect, a diagnostic corroboration is often required for a right treatment.

Effect of tobacco consumption on bone mineral density in healthy young males.

Smoking is related to a decreased bone mass and increased risk of osteoporotic fractures. Nevertheless, the effect of smoking in males is poorly understood. The purpose of this study was to assess the repercussion of smoking on bone mass in otherwise healthy male smokers and its relationship with markers of mineral metabolism and hormone profile. We measured bone mineral density (BMD) in 57 healthy males (26 nonsmokers, 31 smokers; aged 20-45 years) by dual X-ray absorptiometry (DXA, Hologic QDR1000) in the lumbar spine and proximal femur. In a subset we measured biochemical markers of bone metabolism and hormonal profile. We found significant differences in BMD between heavy smokers (more than 20 cigarettes/day) and nonsmokers in all skeletal sites. Serum levels of dehydroepiandrosterone sulfate (S-DHEAS) were lower in smokers and correlated with femoral BMD measurements. No significant differences in bone turnover markers were found. Our findings show that smoking by healthy young males is associated with decreased bone mass.

[Amyloid angiopathy as a clinico-pathological entity to consider in the differential diagnosis of any hemorrhagic cerebrovascular accident]. / La angiopatía amiloide como entidad clínico-patológica a valorar en el diagnóstico diferencial de todo accidente cerebro vascular hemorrágico.

Intracerebral hemorrhages represent about 10% of the whole of vascular cerebral accidents. According to different authors, the incidence of cerebral amyloid angiopathy varies between 5-10% and up to 20-30% of all primary non-traumatic intracerebral hemorrhages. This incidence was analyzed in our environment. A retrospective study was carried out on 403 patients, 203 of them were analyzed between 1990-91 and the other 200 between 1992-3. Age, arterial tension, relapses and localization were taken as criteria for a diagnosis. For the statistical analysis, Student's T-test was used for quantitative variables, while square Chi with Yates' correction was used for qualitative variables. Ischemic cerebral accidents (90.5% of the total) are more frequent than hemorrhagic cerebral accidents, which represent 5.7%. 3.7% were not registered. Therefore, it was suspected cerebral amyloid angiopathy in 1.4% of all vascular cerebral accidents. This represents 26.1% of the total of hemorrhagic patients. Different variables from groups of hemorrhagic vascular cerebral accidents were compared to those caused by amyloid cerebral angiopathy and significant statistics were found with respect to localization in the cerebral hemispheres (p < 0.01). Neither age, nor arterial tension or relapses were significant. Amyloid cerebral angiopathy as a cause of hemorrhagic cerebrovascular accident is and entity to be considered in the diagnosis of these patients. By using clinical criteria and others of localization through complementary explorations, a diagnosis for guessing such a process can be determined.

Bone mineral density, sex steroids, and mineral metabolism in premenopausal smokers.

Smoking is related to decreased bone mass and increased risk of osteoporotic fractures. However, the harmful effects of smoking on bone have not been well characterized. The purpose of this study was to assess the repercussions of smoking on bone mass in premenopausal women, and the relationship between these effects and parameters of mineral metabolism and hormone profile. We measured bone mineral density (BMD) in 101 premenopausal women (47 smokers, 54 nonsmokers) with dual-energy X-ray absorptiometry (DeXA) of the proximal femur and lumbar spine. In a subgroup of the sample (16 smokers, 15 nonsmokers) we measured biochemical indicators of mineral metabolism and hormone profile. BMD in the femoral neck, Ward's triangle, and the intertrochanter region was significantly lower in smokers (P < 0.05) than in nonsmokers. Concentrations of sex hormone-binding globulin were higher, and free testosterone index (FTI) was lower (P < 0.05) in smokers. We found no significant differences between the groups in parameters of mineral metabolism. Concentrations of dehydroepiandrosterone sulfate and free testosterone index were directly correlated with values of BMD in different sites. Our findings show that smoking by premenopausal women is associated with decreased BMD and characteristic changes in the hormone profile.
