A review of 250 patients with the catastrophic antiphospholipid (Asherson's) syndrome (CAPS) taken from the web site organized by the Europhospholipid Group (http://www.med.ub.es/MIMMUN/FORUM/CAPS.HTM) is presented in this paper. A short historical overview of the antiphospholipid syndrome (APS) is followed by a description of the "triggering" factors, associated autoimmune diseases, clinical p...

INTRODUCTION Leptospirosis has recently come to international attention as a globally important re-emerging infectious disease. Our case is unusual given the season, location and setting in which leptospirosis occurred. According to the New York City Board of Health, there were only two other cases of leptospirosis in New York City in the year that our patient was diagnosed. CASE PRESENTATION...

Bacterial infections are an important complication of cirrhosis, particularly in hospitalized patients. In this article we review the prevalence, risk factors, and pathogenesis of bacterial infections in cirrhosis, focusing on the mechanisms of bacterial translocation such as impaired immunity and bacterial overgrowth, as well as maneuvers that may inhibit bacterial translocation and could be u...

Haemophilus parainfluenzae, a human commensal, is an infrequent cause of serious disease. A case of endocarditis caused by this organism in a five year old boy with complex congenital heart disease is reported. The course of this disease was very aggressive, leading to heart failure, disseminated intravascular coagulation and multiorgan failure in spite of appropriate antibiotics and surgical i...

We present a case of severe fatal hepatitis in a young patient presumably triggered by two ubiquitous viral diseases which occurred in close succession. This case is unusual because of the exceptional chronological sequence of primary Epstein-Barr virus and herpes simplex virus type 1 infection causing systemic immune dysregulation associated with rapidly developing liver failure and consecutiv...

We report a case of a premature infant with a vein of Galen malformation (VGM) who presented with high-output heart failure, pulmonary hypertension, and respiratory distress. An echocardiogram showed normal cardiac anatomy, patent ductus arteriosus, and retrograde flow in the descending aorta. Ultrasonography and computed tomography of head confirmed the diagnosis of a large VGM. The patient de...

We report a case of severe systemic loxoscelism in a previously healthy young man. This was associated with a Coombs-positive hemolytic anemia, striking leukomid reaction, renal failure, respiratory failure and cardiovascular collapse. This is the first documented case of a renal biopsy in a patient with renal failure after envenomation by the brown recluse spider. Associated systemic toxicity ...

Macrophage activation syndrome is a form of secondary hemophagocytic lymphohistiocytosis in the setting autoimmune diseases. It’s rare, hyperinflammatory complication requiring prompt institution therapy to prevent organ dysfunction and death. We report young female presenting with macrophage multiorgan failure diffuse alveolar hemorrhage inaugural systemic lupus erythematosus. The patient was ...

Liver abscesses are commonly caused by Enterobacteriaceae and anaerobes. This report is of a patient with liver abscess with massive haemolysis and multiorgan failure caused by Clostridium perfringens. Despite the reportedly high mortality rate and poor prognostic factors, the patient eventually recovered with prompt treatment.
