1/365. Sight-threatening acute orbital swelling from peribulbar local anesthesia.Severe allergic reactions to peribulbar local anesthesia are extremely rare. A 70-year-old woman presented with acute orbital swelling and optic nerve dysfunction after a peribulbar local anesthetic injection. The patient was treated with acute orbital decompression as well as intravenous antibiotics and methylprednisolone; she made a good recovery. An allergy, probably to lignocaine, was the most likely cause. Urgent recognition and treatment of this condition may prevent potentially serious visual consequences.- - - - - - - - - - ranking = 1keywords = dysfunction (Clic here for more details about this article) |
2/365. Postpartum onset of acute heart failure possibly due to postpartum autoimmune myocarditis. A report of three cases.autoimmune diseases, especially autoimmune thyroid disease, frequently develop after delivery due to the immune rebound mechanism. Most cases have transient dysfunction of affected organs. Cardiac dysfunction developed after delivery is called postpartum or peripartum cardiomyopathy. However, the aetiology of the disease is not clarified yet. Here we report three cases that developed acute heart failure in the postpartum period. One was complicated with an atrioventricular block and postpartum autoimmune thyroiditis. All patients recovered to normal cardiac function or pre-attack condition after 1 month of therapy with conventional drugs and bed rest. All three had positive antiheart antibody detected by indirect immunofluorescence assay, and one had antibody to heart myosin detected by enzyme-linked immunosorbent assay. Moreover, one of two patients examined revealed lymphocytic infiltration by endomyocardial biopsy. antibodies to 26 viruses were not elevated significantly during the first 2 weeks after admission in any case. It is strongly suggested that heart failure is induced by postpartum autoimmune myocarditis, and thus clinicians should be aware of this disease.- - - - - - - - - - ranking = 2keywords = dysfunction (Clic here for more details about this article) |
3/365. Utility of thallium-201 scintigraphy in detecting right ventricular dysfunction in pulmonary embolism.Acute right ventricular dysfunction has been established both as a diagnostic and prognostic indicator in pulmonary embolism. This report illustrates the utility of thallium-201 scintigraphy as an adjunctive noninvasive test in the diagnosis of pulmonary embolism by demonstrating increases in regional right ventricular perfusion and its subsequent resolution with treatment presumably as a result of decreased pressure work.- - - - - - - - - - ranking = 166.64001935198keywords = ventricular dysfunction, dysfunction (Clic here for more details about this article) |
4/365. Acute pseudohepatitis in a chronic substance abuser secondary to occult seat belt injury.Causes of a massive elevation in serum aminotransferases (aspartate aminotransferase [AST] and alanine aminotransferase [ALT]) in the substance-abusing patient include viral hepatitis and drug hepatotoxicity. A patient chronically addicted to injection heroin and cocaine presented to the emergency room in a confused state and was admitted to a medical ward with an AST of 4120 U/L, ALT 3820 U/L and right upper quadrant discomfort. Investigations for viral and hepatotoxic causes for the liver dysfunction revealed only hepatitis c seropositivity. A computed tomogram of the abdomen, however, revealed a significant contusion to the right lobe of the liver consistent with traumatic injury. A motor vehicle accident, in which the patient was wearing a seat belt, and which had occurred a few days before admission and had been thought to be minor, was the cause of the liver dysfunction. Significant blunt abdominal traumatic injuries are usually managed exclusively by surgical trauma units. This case underlines the need for medical specialists to be aware of hepatic contusion injuries and to have a high index of suspicion when investigating unexplained hepatocellular dysfunction in chronic substance abusers who have been in motor vehicle accidents.- - - - - - - - - - ranking = 3keywords = dysfunction (Clic here for more details about this article) |
5/365. Acute pulmonary edema associated with placement of waist-high, custom-fit compression stockings.Compression stockings are a safe, noninvasive treatment for patients with symptomatic orthostatic hypotension due to autonomic nervous system dysfunction. In this report, we describe a 75-year-old man who had development of pulmonary edema approximately 45 minutes after placement of compression stockings on the first postoperative day following a carotid endarterectomy. No sudden changes were noted on an electrocardiogram or echocardiogram or in the cardiac isoenzymes associated with the pulmonary edema. The patient had a history of coronary artery disease, diabetes mellitus-induced autonomic nervous system dysfunction, and recent surgery near the carotid baroreceptor. All these factors may have limited his ability to compensate for a rapid increase in central blood volume. The temporal relationship of the patient's respiratory distress to the placement of the compression stockings, in the absence of laboratory findings of primary cardiac dysfunction, make stocking-related fluid shift the likely precipitating event in the formation of acute pulmonary edema. This case suggests that compression stockings should be used with caution in patients with limited cardiac reserve.- - - - - - - - - - ranking = 3keywords = dysfunction (Clic here for more details about this article) |
6/365. Reversible biventricular dysfunction secondary to ischemia in a patient with acute airway obstruction: a case report and review of the literature on reversible causes of acute ventricular dysfunction.Reversible causes of acute myocardial dysfunction are important for clinicians to recognize. Reversible biventricular dysfunction secondary to myocardial ischemia is presented in a patient with acute upper airway obstruction. The differential diagnosis of reversible acute myocardial dysfunction is reviewed.- - - - - - - - - - ranking = 301.95203483356keywords = ventricular dysfunction, dysfunction (Clic here for more details about this article) |
7/365. Acute left ventricular dysfunction and subarachnoid hemorrhage.OBJECTIVE: Severe left ventricular (LV) dysfunction associated with acute subarachnoid hemorrhage (SAH) due to cerebral aneurysm rupture. SETTING: An adult 12-bed surgical intensive care unit of a university hospital. PATIENT: A female patient presenting with SAH (Hunt & Hess grade III) and severe left ventricular dysfunction. INTERVENTIONS: central venous pressure, arterial blood pressure, extravascular lung water catheter, transesophageal echocardiography, blood gas analysis, electrocardiograms, and chest x-ray for clinical management. MEASUREMENTS AND MAIN RESULTS: On admission to the district hospital, an electrocardiogram (ECG) revealed a sinus rhythm with transient ST elevations. A transesophageal echocardiography showed a left ventricular ejection fraction (LV-EF) of approximately 10%. Severe LV dysfunction required inotropic and vasopressor support to maintain mean arterial pressure above 60 mmHg, while the first measurement of an extravascular lung water catheter revealed a cardiac index of 2.0 L/min/m2 and moderate hypovolemia. Despite stepwise volume loading that increased intrathoracic blood volume--an indicator of cardiac preload--from 719 mL/m2 to 927 mL/m2, cardiac index remained poor. enoximone lead to a marked increase of cardiac index up to 3.9 L/min/m2 and LV-EF to about 30%, but had to be stopped due to thrombopenia. Surgical clipping of an intracranial aneurysm was postponed because of the impaired cardiac function and was performed on day 18 after admission. Interestingly, neurologic outcome was not as poor as might be expected from the literature. CONCLUSION: Severe left ventricular dysfunction may occur in acute SAH and may necessitate delay of aneurysm surgery.- - - - - - - - - - ranking = 201.96802322237keywords = ventricular dysfunction, dysfunction (Clic here for more details about this article) |
8/365. myocardial bridging as a cause of acute transient left heart dysfunction.The significance of myocardial bridging is still a matter of debate, and although several reports have underlined its pathologic potential, myocardial bridging is often considered to be a benign phenomenon. We present here the case of a 63-year-old woman with a history of acute left heart failure and ECG evidence of ischemia, and whose primary abnormality on extensive workup was myocardial bridging. This case further underlines that myocardial bridging can lead to significant cardiac events.- - - - - - - - - - ranking = 4keywords = dysfunction (Clic here for more details about this article) |

Acute hyperphosphatemia caused by sodium phosphate enema in a patient with liver dysfunction and chronic renal failure.We report a case of acute hyperphosphatemia secondary to rectal administration of sodium phosphate and sodium biphosphate (Fleet enema). parathyroid hormone and calcitonin levels were measured along with phosphate clearance and the tubular reabsorption of phosphate.- - - - - - - - - - ranking = 4keywords = dysfunction (Clic here for more details about this article) |
10/365. IgG anti-GQ1b positive acute ataxia without ophthalmoplegia.IgG anti-GQ1b antibody was present in a patient with acute ataxia and areflexia without ophthalmoplegia or elementary sensory loss. Sensory nerve conduction studies and somatosensory evoked potentials were normal, but postural body sway analysis showed dysfunction of the proprioceptive afferent system. The clinical presentation and laboratory results for this patient resemble those of miller fisher syndrome, except for the lack of ophthalmoplegia. This case may represent part of an IgG anti-GQ1b syndrome.- - - - - - - - - - ranking = 1keywords = dysfunction (Clic here for more details about this article) |
