Changes in the definition of terms relating to the diagnosisof myocardial infarction (MI) have evolved by better understandingof the pathophysiology culminating in the new term of acutecoronary syndrome (ACS). Figure 1 illustrates the processesthat occur in the development of an acute coronary event.

Impact of clinical history on fracture detection with radiography   总被引:3,自引:0,他引:3  
Berbaum  KS; el-Khoury  GY; Franken  EA  Jr; Kathol  M; Montgomery  WJ; Hesson  W 《Radiology》1988,168(2):507-511
The effect of knowledge of localizing symptoms and signs in the detection of fractures was studied. Forty radiographs of the extremities were examined twice by seven radiologists; the sessions were separated by 4 months. In 26 cases, a subtle fracture was present; 14 cases were normal. In half of the cases at each session, the precise location of pain, tenderness, or swelling was provided. The observer was asked to determine if the case was normal or abnormal (provide the exact location of the fracture) and to indicate the degree of confidence in the diagnosis. Responses were converted to a numeric scale for analysis. Analysis of receiver operator characteristic parameters indicates that clues regarding location of trauma facilitate detection of fractures. The improvement is based largely on an increased true-positive rate without an increased false-positive rate, regardless of the decision criteria of the radiologist (overall willingness to "overread" or "underread"). This has direct clinical applicability and reinforces the plea of radiologists for precise clinical information.  相似文献

Clinical and genetic features of variegate porphyria in a Chinese patient     
Chow KM  Hui CF  Kay R  Wong KS  Lam CW 《中华医学杂志(英文版)》2001,114(4):424-427
Acute porphyria is rare in orientals. We describe a Chinese woman with recurrent generalised tonic-clonic seizures and abdominal pain. Genomic DNA studies identified a heterozygous base substitution from guanine to adenine at nucleotide position 503, resulting in substitution of arginine by histidine at position 168 of the protein (R168H). This genetic abnormality is similar to the mutation reported in Caucasians with variegate porphyria. To the best of our knowledge, this is the first report in the English literature a Chinese patient with variegate porphyria with an identifiable mutation. A brief review of porphyria is presented.  相似文献

Racism in psychiatry: paradigm lost--paradigm regained     
Bhugra D  Bhui K 《International review of psychiatry (Abingdon, England)》1999,11(2-3):236-243
Racism and psychiatry have been 'linked' in the public imagination, largely because psychiatry is seen as an instrument of social control, and racism as a different form of oppression which permeates society at large. Racism in psychiatry is often believed to be the mediating factor in cases of 'psychiatric misdiagnosis' and 'mismanagement.' Misdiagnosis includes underdiagnosis and overdiagnosis; this can account for the non-delivery of appropriate treatments because of an erroneous diagnostic label. In some instances this leads to a deferred intervention, or in some ethnic groups, help-seeking is delayed for unnecessarily long periods. Racism is not a recent phenomenon. The blunt application of the word 'racism' perpetuates conceptual confusion about what is meant by the term, what processes are taking place, how much of the processes are institutionalized or individual and to what degree individuals are aware of the impact of their actions. We propose a way of understanding racism in psychiatric practice, and suggest that within such a framework, the therapist/professional and the patient can work together towards improving patient care.  相似文献

Bladder pheochromocytoma encountered on sonography     
M elikta  N Okur  KS Aikimbaev  F Binokay  M Sert  E Akgül 《Journal of Medical Imaging and Radiation Oncology》2004,48(3):398-400
Pheochromocytomas of the bladder are rare neoplasms, constituting <0.06% of all vesical tumours. Common presenting features of this tumour include episodes of sweating, hypertension, haematuria and postmicturition syncope. We describe a case of bladder pheochromocytoma in a 66‐year‐old man whose only symptom of macroscopic haematuria was initially assessed with ultrasonography. Clinical presentation highlights the need for a high index of suspicion during sonographic evaluation of bladder neoplasms because such tumours might present without symptoms of adrenergic excess.  相似文献

Common mood and anxiety states: gender differences in the protective effect of physical activity     
Bhui K  Fletcher A 《Social psychiatry and psychiatric epidemiology》2000,35(1):28-35
Background: We wished to examine the impact of the duration and intensity of physical activity on common anxiety and depressive states. Method: A nested case-control design was applied to data from the Health and Lifestyle Survey. Anxiety and depressive states were measured by caseness on the General Health Questionnaire. Physical activity variables were defined from a detailed activity schedule. Results: After adjustment for potential confounders, the findings suggest that compared to men who reported 0–44 min of daily physical activity, there is benefit to men who exercise for at least 92 min a day (92–161 min a day: OR = 0.57, 95% CI = 0.37–0.87, P < 0.01; 162–554 min a day: OR = 0.65, 95% CI = 0.43–0.97, P < 0.05), but not to women. The protective effect does not appear to vary according to the intensity of activity in men or women. Conclusions: Physical activity of long duration amongst men confers protection against common mood and anxiety states. This study found no such protection for women.

Pegylated liposomal doxorubicin plus highly active antiretroviral therapy versus highly active antiretroviral therapy alone in HIV patients with Kaposi's sarcoma     
Martin-Carbonero L  Barrios A  Saballs P  Sirera G  Santos J  Palacios R  Valencia ME  Alegre M  Podzamczer D  González-Lahoz J;Caelyx/KS Spanish Group 《AIDS (London, England)》2004,18(12):1737-1740
Twenty-eight HIV patients either naive or failing highly active antiretroviral therapy (HAART)with moderate-advanced Kaposi's sarcoma (KS)were randomly chosen to initiate a new HAART regimen plus pegylated liposomal doxorubicin(PLD) or the new HAART regimen alone. After 48 weeks, better response rates were observed in the HAART plus PLD group (76% versus 20%).In HIV-infected patients with moderate-advanced KS, HAART alone may not be enough for KS response.  相似文献

The first 150 words of the full text of this article appear below. Key points Coronary artery disease accounts for >30% ofdeaths in Western society. The diagnosis of myocardial infarctionshould be qualified by size, causation and time from occurrence. Mortalityis reduced by immediate or ‘primary’ percutaneouscoronary intervention or thrombolysis within the first 24 hof onset of ST-segment elevation myocardial infarction. Strategiesto reduce platelet activation (glycoprotein IIb/IIIa receptorantagonists, or clopidogrel) are now recommended in the treatmentof high-risk non-ST-segment myocardial infarction/unstable angina. Elevatedserum troponins may be the result of non-ischaemic myocardialdamage, especially in critical illness.
