Acute Pulmonary Edema as the Initial Hospital Presentation of Systemic Lupus Erythematosus

Acute pulmonary edema is an unusual initial presentation for systemic lupus erythematosus. A 46-year-old woman required intensive care for life-threatening pulmonary edema of unknown etiology, which was unresponsive to conventional treatment. Her condition improved only when pulse corticosteroid therapy was initiated, with clinical and echocardiographic improvement in cardiac function. The diagnosis of systemic lupus erythematosus was then made, based on immunologic tests and renal biopsy. The patient's condition remained stable only with continuation of appropriate therapy for systemic lupus erythematosus.

The natural history and management of recurrent corneal erosion: A prospective randomised trial

One hundred and seventeen patients with a history of recurrent corneal erosion were recruited at initial hospital presentation. Seventy-five cases had a history of shallow corneal injury, 23 had epithelial basement membrane dystrophy (EBMD), 8 had both and 11 had neither. Mean age at presentation was 38 years and follow-up ranged from 6 to 16 months (mean 10.6 months). Sixty-one patients presented with a first acute corneal erosion, 21 with a subsequent acute corneal erosion and 35 with chronic symptoms. Patients with EBMD or a trauma-related focal epithelial basement membrane abnormality were more likely to present with chronic recurrent symptoms than trauma-related cases with no abnormality on examination. Both EBMD and trauma-related cases typically recurred in the lower half of the cornea, frequently in the midline (z = 7.3, p < 0.0001), suggesting an intrinsic or acquired abnormality of the epithelial basement membrane at this site. Only four of 82 acute episodes did not resolve by 5 days with simple patching, cycloplegia and topical antibiotic ointment. In the vast majority of patients presenting with an acute erosion, simple management measures only are required. Of 117 cases started on prophylactic ointment at night, further therapy due to prophylaxis failure was required in only 5. EBMD was a risk factor for failure (relative risk 10.77). There was no difference in efficacy between once daily prophylactic paraffin and hypertonic saline ointments (p = 0.17), suggesting they both have only a lubricant action.

Interleukin-8 and development of adult respiratory distress syndrome in at-risk patient groups

Neutrophils have been implicated in the pathogenesis of the adult respiratory distress syndrome (ARDS). We have measured concentrations of the neutrophil attractant interleukin-8 in blood and bronchoalveolar lavage fluid (BAL) from patients at risk of ARDS. We studied 29 patients from three groups at risk of developing ARDS: multiple trauma (n=16), perforated bowel (n=6), and pancreatitis (n=7). ARDS developed in 7 of these patients. Interleukin-8 in BAL and blood samples taken on initial hospital presentation was measured by a sandwich enzyme-linked immunosorbent assay. The mean BAL interleukin-8 concentration was significantly higher for the patients who subsequently progressed to ARDS than for the non-ARDS group (3·06 [SE 2·64] vs 0·053 [0·010] ng/mL, p=0·0006). There was no difference between the groups in plasma interleukin-8 (6·23 [2·60] vs 5·12 [2·22] ng/mL, p=0·31). Immunocytochemistry suggested that the alveolar macrophage is an important source of interleukin-8 at this early stage in ARDS development. This study provides evidence of a relation between the presence of interleukin-8 in early BAL samples and the development of AR DS. The early appearance of interleukin-8 in BAL of patients at risk of ARDS may be an important prognostic indicator for the development of the disorder and reinforces the likely importance of neutrophils and the effects of their accumulation and activation in the pathogenesis of many cases of ARDS.

Intravenous streptokinase infusion in acute myocardial infarction with electrocardiographic monitoring for myocardial reperfusion

We present a case of thrombolytic therapy for acute myocardial infarction with high-dose intravenous streptokinase infusion in the emergency department. Resolution of ST segment elevation and relief of chest pain occurred within one hour of the infusion, and coronary angiographic study six days later showed a significant proximal obstruction (80%) of the right coronary artery. The patient underwent coronary artery bypass surgery eight weeks after his initial hospital presentation.
