[Epidemiological events related to decompensated heart failure]. / Factores epidemiológicos asociados a la hospitalización por descompensación de la insuficiencia cardiaca.

OBJECTIVE: The present study aimed to evaluate the profile of patients with decompensated heart failure hospitalized in a tertiary hospital. METHODS: It was designed an observational and retrospective study where data from clinical records of patients suffering from heart failure along 2005 were registered randomly. RESULTS: 209 patients were collected (average age: 78.6 +/- 9.1; male: 52.4%) with a comorbidity rate of 87.55%. Almost one third of them have not stimation of systolic function and among the others 72.4% have it preserved. Most of decompensated were due to respiratory infections. Ischemic-hipertensive cardiopathy was the most frequent aetiology of systolic disfunction. Average stay was 12.9 days with a mortality rate of 9.56%. Its main risk factors were advanced stages in NYHA od Red Cross scales, as so as dementia or ictus. CONCLUSIONS: The present study shows a patient hospitalized for decompensated heart failure roughly different from that one reported at clinical trials. It makes difficult to apply therapeutical interventions, previously well documented to be useful.

[Pacemaker endocarditis]. / Endocarditis del marcapasos.

Pacemaker endocarditis is a rare but serious complication of permanent transvenous pacing. The most common presentation is fever syndrome or gram positive bacteremia. For the diagnostic it is important to performed blood cultures and an echocardiography. A retrospective study included the cases of pacemaker endocarditis diagnosed in the Internal Medicine Department of our Hospital between 1989-2003. Six patients were included. Repeated manipulation of the system and diabetes were the most frequent risk factors. The most frequently detected causative microorganisms were Staphylococci. In spite of the low sensitivity of the transthoracic echocardiography in expert hands it can improve, in this series it places in 66 %. Surgical treatment with cardiopulmonary bypass and implantation of a new system was performed in the same intervention in all patients. None relapsed and the overall mortality was 17%.

[Pacemaker endocarditis]. / Endocarditis del marcapasos.

In the last years an increment has taken place in the pacemaker and implantable cardioverter-defibrillator indications that will have as consequence an increase of the prevalence of endocarditis associated to intravascular devices, for what acquires special relevance for the clinician to know this entity and to include it in his differential diagnoses. The objective of this article is to describe the epidemiology, clinic characteristics, diagnosis, treatment and outcome of the pacemaker endocarditis.

[Controversies in infective endocarditis]. / Controversias en endocarditis infecciosas.

The infective endocarditis is defined mainly as the infection of the internal surface of the heart, affecting to the cardiac valves although it can also do it to the septos, the tendinosas cords or endocardio mural. Around the origin, the diagnosis and the treatment of the disease, a considerable controversy has taken place. In this sense, basic criteria exist that they define to the infective endocarditis; however, particular situations are appraised in which the meticulous study is essential from the patient, doing special reference to the origin agents and, more in particular, to the fungal endocarditis.

[Drug interactions in the prescription of medical patients at hospital discharge]. / Interacciones entre medicamentos prescritos al alta en un Servicio de Medicina Interna.

OBJECTIVES: To detect and evaluate the clinical significance of drugs interactions in patients discharged from hospital. MATERIAL AND METHODS: We retrospectively screened the medication for potential drug interactions of 412 patients discharged. Interactions were catalogued according to clinical importance following the Hansten and Horn's classification. RESULTS: Three hundred twenty-nine potential interactions were detected. The 39.9% of the patients had at least one potentially interacting drug combination. The 52.6% of the interactions were catalogued as Class 3, bearing in mind minimizing the risk of the interaction. We did not find any Class 1 or 2 interactions, which have potentially major severity. Oral anticoagulants and digoxin were the most frequently implicated drugs. The patient monitoring was well done in the 100% of the interactions of Oral anticoagulants with other drug, but in the interactions of digoxin with another, this control was not done adequately. One patient was rehospitalised due to high levels of digoxin, he had been discharged with two potential interactions. CONCLUSIONS: The frequently of potential drug interactions in medical patients at hospital discharged was high, but the clinical significance appear to be low.

[Spondylodiskitis caused by Candida albicans. Report of two new cases]. / Espondilodiscitis por Candida albicans. Aportación de dos nuevos casos.

Recently, candidiasis infection is on the increase and several factors have been associated, such us immunodepression, catheters, weakening diseases, prolonged antibiotherapy, HIV infection and IDU. Spondylodiskitis due to Candida sp. is a rare entity. Two cases of spondylodiskitis due to Candida albicans were diagnosed: a 29 year old man and a 35 year old woman. Both were IDUs with a previous history of HIV infection. The most prominent clinical features in both cases were pain, fever and constitutional syndrome. We describe the clinical, diagnostic, and therapeutic features of both cases.

[Partial bilateral rupture of the Achilles tendon associated to levofloxacin]. / Rotura parcial bilateral aquílea asociada a levofloxacino.

Fluoroquinolones-associated tendonitis and tendon rupture are well described in the literature but these are not frequently observed and related to the new agents of this group, as levofloxacin. This is probably due to the recent introduction and expansion. Although epidemiological studies are needed to know the frequency of that levofloxacin-induced tendinopathies, case-report could alert to the physicians about this possible severe adverse reaction. We present a case of bilateral Achilles tendonitis with partial spontaneous rupture probably associated to levofloxacin.

Use of ligase chain reaction for the rapid diagnosis of lymph node tuberculosis.

Ligase chain reaction amplification (LCx Abbott Laboratories) was used to detect the presence of M. tuberculosis in 101 adenopathy specimens obtained from 98 patients. A total of 30 cases of lymph node tuberculosis were diagnosed, and the data were compared with results obtained using conventional techniques. The sensitivity of auramine staining and culture were 50.0% and 66.7%, respectively. The sensitivity, specificity, positive predictive value and negative predictive value of the LCx assay were 80.0, 98.6, 96.0, and 92.1% respectively. The results confirm the reliability of ligase chain reaction amplification for the detection of lymph node tuberculosis.

[Tuberculous peritonitis: a Third World's disease?]. / Peritonitis tuberculosa: ¿una enfermedad del tercer mundo?

Tuberculous peritonitis has a high morbidity and mortality. The clinical outcome of tuberculous peritonitis depends on an early diagnosis and treatment. We review five cases of tuberculous peritonitis diagnosed in a short stay medical unit over a one-year period. All patients were successfully treated with antituberculous drugs. The clinical management of this disease is described and current views regarding the value of computed tomography and other diagnostic techniques are discussed.

[Inflammatory pseudotumor of the spleen. Review and a new case report]. / Pseudotumor inflamatorio del bazo. Revisión y aportación de un nuevo caso.

Splenic inflammatory pseudotumour has been defined as a benign tumour reactive lesion with unspecified reparative or inflammatory alterations. It is a mimicking tumour often confused with other pathologies, primarily, lymphoproliferative disorders. Though its aetiology remains unknown, these tumours are often associated to infectious agents such as the Epstein-Barr virus. We describe a case of a 29 year-old patient with a history of infectious mononucleosis, followed by fever, weight loss, and splenomegaly. Splenectomy detected a homogeneous, whitish 2 cm node diagnosed as splenic inflammatory pseudotumour. The clinical features and diagnosis of this disorder are discussed in relation to the histopathological findings.

[Statin-induced rhabdomyolysis and renal failure: also with fluvastatine]. / Rabdomiolisis y fallo renal por estatinas: también con fluvastatina.

Hydroximetilglutaril-coenzima A reductase inhibitors (statin) have the potential to cause rhabdomyolysis. However, fluvastatin is rarely associated with rhabdomyolysis when compared to other statins. Differences in biochemical and pharmacokinetic properties between fluvastatin and the other statins have been invocated in order to explain the apparent comparative safety of fluvastatin. We present a case of rhabdomyolysis with acute renal failure in a patient receiving fluvastatin and, following the Karch-Lasagne algorithm, we present evidence that this case was an adverse reactions to fluvastatin.

[Resistant tuberculosis by drugs]. / Tuberculosis resistente a fármacos.

Among all infectious diseases, tuberculosis has probably been the most frequent cause of death and morbidity in the history of humanity. On a world-wide basis, the tuberculosis (TB) represents a serious public health problem, existing great differences between developed and developing countries in terms of controlling the disease. One of the problems inherent in this disease is the resistance of Mycobacterium tuberculosis to drugs, specially the multi-resistance (defined as resistance to isoniziade and rifampicine), it represents a problem of global health. Faced with clinical suspect, its diagnosis must be immediately done and treatment must be started as soon as possible. For this purpose, we have at our disposal such effective diagnosis and therapeutic methods. However, the most important the most important action is that all these patients must be subjected to a close evolved control carried by specialized units.

[A rare presentation of tuberculosis. Miliary tuberculosis in a immunocompetent patient]. / Rara presentación de tuberculosis. Afectacón miliar en paciente inmunocompetente.

Currently, miliary TB has a higher incidence among the elderly and immunodepressed patients, and exceptionally in young adults. A case of miliary tuberculosis was diagnosed in a young immunocompetent patient without using invasive techniques. The clinical and diagnostic implications will be discussed.

[Oral anticoagulation]. / Anticoagulación oral.

The use of oral anticoagulants in the prevention of thrombotics processes, has experienced a considerable increase. In addition, there are a growing experience on the medical and socials consequences of the use of this drug. This has originated a much more pragmatic vision of the daily handling of the anticoagulated patient. In this article, we made are vision about the indications and the practical use, including some useful advices and criteria for the concomitant drug selection.
