1/8. Medical treatment of the adolescent drug abuser. An opportunity for rehabilitative intervention.Illnesses related to both the pharmacologic properties of abused substances and their methods of administration often bring the teenager to medical attention and may provide sufficient motivation for the adolescent to seek help beyond the acute problem. Successful treatment of an overdose reaction, an abstinence syndrome, or any other medical complication of drug abuse may give the physician a unique opportunity to begine further evalution for future care.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
2/8. Echocardiographic evolution of left ventricular and left atrial thrombi in a patient with left ventricular dysfunction due to alcoholic cardiomyopathy, chronic atrial fibrillation and multiple non-fatal systemic embolisms.The echocardiographic characteristics and evolution of multiple pedunculated left atrial and left ventricular intracavitary thrombi in a patient with alcoholic cardiomyopathy are reported. The patient had a long history of left ventricular dysfunction and atrial fibrillation but the referring physician had not prescribed anticoagulant prophylaxis. Multiple, non-fatal, systemic embolizations occurred during hospitalization and echocardiography was used to monitor the effect of the anticoagulant therapy on the remodelling and final dissolution of intracavitary thrombi.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
3/8. Unusual manifestations of peripartal cardiac disease.Because peripartal cardiac disease occurs infrequently, its manifestations may be unfamiliar to most physicians. We report two unusual cases of postpartum cardiac disease: one patient presented with cerebral and peripheral arterial embolization, and the second patient developed late eclamptic seizures with subsequent myocardial infarction. Both patients recovered. Nonobstetric physicians should be aware of these pregnancy-associated medical complications to allow prompt diagnosis and aggressive therapy.- - - - - - - - - - ranking = 2keywords = physician (Clic here for more details about this article) |
4/8. A case of Purtscher's retinopathy.This article describes a case of Purtscher's retinopathy, a syndrome believed to be caused by microembolic infarction of the retina, in a 20-year-old man after remote extraocular trauma. The patient jumped from a 20-meter high building. He suffered multiple crush injuries, but a computed tomographic scan of the brain and orbit was normal. More than 1 month after injury, his visual acuity diminished to light perception in the right eye and counting fingers in the left. The ophthalmoscopic picture was characteristic of Purtscher's retinopathy with cotton-wool exudates and retinal hemorrhages localized to the posterior pole. His vision was improved only slightly 6 months later. Although rare, emergency physicians should be familiar with this entity as a cause of diminished vision associated with extraocular trauma.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
5/8. Acute renal vascular occlusion: an uncommon mimic.Two adult patients with acute renal vascular occlusion with infarction are described. Both patients were believed to have ureteral colic. In each instance, the correct diagnosis was overlooked at the initial emergency department visit. An uncommon clinical entity that continues to go undiagnosed, acute vascular occlusion of the kidney must be considered in the differential diagnosis of acute flank pain. Absence of the nephrogram phase on an intravenous pyelogram (IVP) should alert emergency physicians to this possible diagnosis and to the need for further work-up. Subsequent diagnostic evaluation should begin with renal ultrasonography to rule out obstructive uropathy. If hydroureteronephrosis is not present, follow-up perfusion studies are necessary to confirm the absence of renal perfusion. Greater awareness of this uncommon clinical entity and its potential morbidity is essential to correct diagnosis and management.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
6/8. Peripartum complications. hemorrhage, embolism, hypertension, and infection.Maternal peripartum complications continue to be a significant problem in the united states, even among previously healthy women. The problems include peripartum bleeding, infection, hypertension, and thromboembolic disease. Primary care physicians are often called upon to treat these conditions. An awareness of the approach to diagnosis and management helps to ensure optimal outcome.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
7/8. Trousseau's syndrome.We report 4 cases of Trousseau's syndrome, in which spontaneous recurrent or migratory venous thromboses, arterial emboli caused by nonbacterial thrombotic endocarditis, or both, develop in a patient with a recognized or occult malignant tumor. The clinical course of 3 of the patients emphasizes a key point: The occurrence for no known reason of thromboses preventable by anticoagulation therapy with heparin but not with warfarin sodium should alert a physician to focus diagnostic efforts on uncovering an underlying malignant lesion. Thromboses may occur months to years before the tumor is discovered, and a thorough negative initial examination does not obviate the need for a continuing search. patients with Trousseau's syndrome have persistent low-grade intravascular coagulation, and therapy with heparin should be continued indefinitely. Stopping heparin therapy for even a day may permit a new thrombosis to develop. Immunostaining a biopsy specimen from 1 patient provided evidence that 2 properties of a neoplastic lesion are required for the syndrome to develop: The malignant cells express surface membrane tissue factor, and structural features of the tumor permit the malignant cells or vesicles it sheds to be exposed to circulating blood.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
8/8. Interphysician agreement in the diagnosis of subtypes of acute ischemic stroke: implications for clinical trials. The TOAST Investigators.To test interphysician agreement on the diagnosis of subtype of ischemic stroke, we sent subtype definitions and 18 case summaries (clinical features and pertinent laboratory data) to 24 neurologists who have a special interest in stroke, and asked them to determine the most likely subtype diagnosis. The overall agreement was 0.64 (Kappa [K] = 0.54). Interphysician agreement was highest for the diagnoses of stroke secondary to cardioembolism (K = 0.75) or to large-artery atherosclerosis (K = 0.69). Individual physicians varied widely; four agreed with the consensus diagnosis in all 18 cases, while six others disagreed with the consensus diagnosis in three to five cases. Our level of interphysician agreement is greater than that reported in other studies and was substantial. However, despite using subtype definitions and being given extensive information often not available in the acute setting, physicians still disagree about the etiology of stroke, particularly in regard to stroke due to small-artery occlusion or of undetermined etiology. physicians seem reluctant not to attribute stroke to a specific etiology. The uncertainty about subtype diagnosis will affect interpretation of the results of clinical trials in patients selected by the subtype of ischemic stroke and also suggests that results of treatment as affected by subtype should be cautiously interpreted unless efforts to assure uniformity are included in the trial's operations. Refinement of algorithms for determining subtype of ischemic stroke do improve interphysician agreement. Such criteria should be applied strictly, and trials should include measures to assure the most uniform diagnosis of stroke subtype possible.- - - - - - - - - - ranking = 10keywords = physician (Clic here for more details about this article) |
