[Acute aortic dissection].

OBJECTIVE: Acute aortic dissection is a medical emergency associated with high rates of mortality. Despite recent diagnostic advances, prompt and accurate diagnosis is difficult. We present a review of the a medical emergency service experience to diagnosis, factors associated to prompt diagnosis and inhospital evolution. MATERIAL AND METHOD: We studied 86 consecutive patients who had aortic dissections, to assess the presentation, management, and outcome. RESULTS: Mean age 61.9 +/- 12.5 years, 80% male. Hypertension was the most common predisposing factor (65% of patients overall). Chest pain was the most common initial complaint (58%). The initial clinical impression was aortic dissection in 56% of patients overall. Computed tomography was diagnostic in 96% when used. 62% underwent surgery. Overall in-hospital mortality was 28%. CONCLUSIONS: Acute aortic dissection presents with a wide range of manifestations. A high clinical index of suspicion and a prompt computed tomography should to improve recognition of aortic dissection.

[Diabetic ketoacidosis in an emergency department].

OBJECTIVE: We study clinical data and differences in the patients with Diabetic Ketoacidosis (CAD) attended in an Emergency Department (ED). METHODS: We described 15 patients with criteria for diagnosis of CAD during a 12-month period. We value prospectively clinical data, precipitating factors, diagnosis associated, previous diagnosed diabetes, complications, mortality and use of and intensive care unit (UCI). We comparing groups according two characteristics: age group and prior diagnosis of diabetes mellitus.

[Dystomatosis produced by fasciola hepatica: three cases in Madrid].

Three cases of hepatic fascioliasis diagnosed in the Department of Internal Medicine are presented. All of the patients live in Madrid, all were fed watercress in the last month and the diagnosis was established during the invasive phase and confirmed by serological testing. We emphasized the importance of the TC scan in the correct diagnosis, the ectopic location of the parasite presentation like subcutaneous thoracic nodule and the efficacy of bithionol in the treatment.

[Community-acquired pneumonia in the aged: prognostic factors].

We studied the clinical characteristics and the initial supplementary test available in the emergency service, in aged patients with community-acquired pneumonia, as well as their mortality prognosis value. We assessed 190 patients attended consecutively during one year. Clinical, analytical and radiological data were registered. The parameters associated to a higher mortality were: age, absence of thoracic pain, reduction in the level of consciousness, leukocytosis, increased urea levels, aminotransferases, lactate dehydrogenase and reduction in prothrombin activity and pH. The data associated to a greater relative risk were: age above 80 years, absence of thoracic pain, prothrombin activity lower than 70% and ALT < 40 U/l. The presence of three to four of these variables had a sensitivity of 62% and a specificity of 94% in the prediction of mortality. In the multivariable analysis, the following variables remained significative: age, obnubilation and decrease of prothrombin. We stress the relevance of a high clinical suspicion, given the frequency of these cases with little symptomatology, in order to allow for an early treatment and the identification of right risk patients at the initial assessment.

[Rhabdomyolysis in acute intoxications].

The development of rhabdomyolysis is a complications of acute intoxications, although its actual incidences is unknown. We had studied the frequency and differential characteristics of the patients with such complications. A prospective study was conducted with 200 patients admitted to a General Hospital from an urban area due to acute intoxication, recording the etiology of the intoxication, motivation and analytical characteristics of the patients with rhabdomyolysis compared to their patients without rhabdomyolysis. The incidence of rhabdomyolysis was 7.7%. Among the patients with rhabdomyolysis, ludic motivation (59%) and etiology associated to drug abuse (heroin 30%, cocaine 24%) were more frequent compared to the patients without rhabdomyolysis. Twenty per cent of the patients consuming cocaine and 17% of the patients consuming heroin developed rhabdomyolysis. Acute rhabdomyolysis was, thus, a significant complication of acute intoxications, associated to the consumption of illegal drugs and, at least in our cases, with a good evolution regarding the renal function.

[Cardiovascular complications due to cocaine].

The increase of cocaine consumption is a common new item in the medical literature and in the national press and, hence, it does not surprises us any more. However, we are seeing every day the appearance of unknown or forgotten complications. In this paper, we review the cardiovascular complications due to the consumption of this drug, stressing the physiopathological mechanisms and the therapeutical aspects. In addition, we describe our experience with the management of these patients.

[Impact of arterial hypertension on the central nervous system].

Cerebrovascular diseases (CVD) entail high costs associated to therapies, hospitalizations and disabilities. Arterial hypertension (AHT) is the major modifiable risk factor for the development of all types of CVDs (cerebrovascular accidents, vascular dementias, etc.). The increase of arterial pressure causes functional and anatomical changes in the cerebral circulation which facilitate the development of CVDs. The time of evolution and the severity of the AHT, as well as the associated vascular risk factors, will determine its impact on the central nervous system.

[Intraparenchymal cerebral hemorrhage and cocaine].

Medical problems related to cocaine consumption are not rare in our environment; however, to this respect, descriptions in the spanish literature are scarce. We present three cases of intracerebral hemorrhage which occurred after cocaine consumption (intranasal route in two cases and intravenous route in one case). In the three cases, another associated risk factor was observed (alcohol in one case, hypertension in other case, arteriovenous malformation in the third case). We comment on the pathophysiological theories of the cause of bleeding, high-lighting the routine search of this association.

[Rhabdomyolysis and cocaine consumption: presentation of 13 cases].

We present 13 cases taken care at the Emergency Service, whose diagnosis was acute rhabdomyolysis related to consumption of illicit drugs. In all cases, the presence of cocaine in the urine was detected. Clinical features, other associated factors and complications are described, stressing the etiopathogenic mechanism of presentation of cocaine-related rhabdomyolysis.

[Atrial fibrillation and cerebral infarct].

The importance of atrial fibrillation (AF) as a risk factor (RF) for cerebral infarction (CI) is well-known. It is probably caused by cardiac embolism but other explanations can also justify this association. Our aim was to analyse the features of the patients with CI and AF and sinus rhythm (SR), as well as to form hypotheses as regards the pathogenesis. 250 patients with CI, 204 in RS and 46 in AF (31 non-valvular and 15 associated to a valvular disease) were studied, analysing the prevalence of RF and initial blood tests. The group of patients with valvular AF of probably embolic mechanism had a minor prevalence of RF (hypertension, diabetes, smoking, alcoholism) but higher mortality. The group with non-valvular AF, had a lower RF prevalence compared to the SR group (non-embolic mechanism), without statistical significance and with a similar mortality rate. We concluded that the atherothrombotic mechanism can be the cause of a considerable proportion of CI in patients with non-valvular AF.

[Risk factors in cerebrovascular disease and their prognostic importance].

The prevalence of cerebrovascular disease risk factors and their immediate mortality prognostic value together with the initial analytical parameters are evaluated. 250 cases of cerebral infarction (CI), 150 cases of intracerebral hemorrhage (ICH) and 60 cases of transitory ischemic events (TIE) were studied and compared to a control group. A higher prevalence of arterial hypertension, cardiopathy, previous cerebrovascular disease and elevated hematocrit was found in the CI group. In the TIE group there was an increased prevalence of cardiopathy, previous cerebrovascular disease and high hematocrit. In the ICH group an increased prevalence of hypertension and left ventricular hypertrophy was found. We have to point out the importance of a global approach of the risk factors. The intrahospital mortality due to CI was associated with old age, low hematocrit, leukocytosis and high blood sugar at admission. ICH was associated with a higher systolic arterial pressure leukocytosis and elevated blood glucose at admission.
