Acute renal embolus is rarely reported in the medical literature; thus, accurate data regarding presentation, laboratory tests, diagnostic techniques, and treatment are lacking. To better define this condition, we examined the medical records of all patients admitted to Kaplan Medical Center and Sheba Medical Center in central Israel from 1984 to 2002 who had a diagnosis of renal infarction and atrial fibrillation. We noted demographic, clinical, and laboratory parameters; method of diagnosis; treatment received; and patient outcome. We identified 44 cases of renal embolus: 23 females and 21 males, with an average age of 69.5 +/- 12.6 years. Thirty (68%) patients had abdominal pain, and 6 (14%) had a previous embolic event. Nine patients were being treated with warfarin on admission, 6 (66%) of whom had an international normalized ratio (INR) < 1.8. Hematuria was present in 21/39 (54%), and 41 (93%) patients had a serum lactate dehydrogenase (LDH) level > 400 U/dL. The mean LDH was 1100 +/- 985 U/dL. Diagnostic techniques included renal isotope scan, which was abnormal in 36/37 cases (97%); contrast-enhanced computed tomography (CT) scan, which was diagnostic in 12/15 cases (80%); and ultrasound, which was positive in only 3/27 cases (11%). Angiography was positive in 10/10 cases (100%). Twenty-three (61%) of 38 patients had normal renal function on follow-up. The 30-day mortality was 11.4%. Renal embolus was diagnosed mainly in patients aged more than 60 years, some of whom had a previous embolic event. Most of those receiving anticoagulant therapy had a subtherapeutic INR. Abdominal pain was common, as well as hematuria and an elevated LDH. These patients are at risk of subsequent embolic events to other organs. The most sensitive diagnostic technique in this population is a renal isotope scan, but contrast-enhanced CT scan requires further assessment.

Hepatitis E virus (HEV) is an enteric virus that usually causes a self-resolving hepatitis; although, it may be fatal, especially in pregnant women. Although HEV is endemic in Israel, there have been no recent local outbreaks. We report the case of a 70-year-old man who presented with painless jaundice. Ultrasound and abdominal computed tomography scan revealed gallstones, with no evidence of cholecystitis and no dilatation of the intra-or extrahepatic bile ducts. An open cholecystectomy was performed with intraoperative cholangiography. There was no evidence of choledocholithiasis. A subsequent endoscopic retrograde cholangiopancreatography was normal. His bilirubin level subsequently increased to a maximum of 25 mg/dL, and his gamma-glutamyl-transferase level reached 1,400 U/L. There was no evidence of any autoimmune or metabolic disease, and routine viral serology was normal except for immunoglobulin G to hepatitis A virus. A liver biopsy revealed an acute cholestatic picture. The jaundice resolved slowly after a period of 6 months. Hepatitis E virus RNA was isolated from the acute-phase serum and was not detectable in the convalescent serum. This case is a unique example of chronic cholestatic jaundice that we think is caused by acute HEV infection.

Septic arthritis is usually of hematogenous origin and is increasingly being reported in elderly patients, who often have underlying medical conditions such as diabetes or alcoholism. We report a 62-year-old patient with alcoholic liver disease who presented with Escherichia coli bacteremia and septic arthritis in a previously fractured ankle. There are scarce reports of infectious arthritis in cirrhotic patients, but this is the first report of arthritis after a primary enteric bacteremia. We believe that the patient described here developed E. coli bacteremia as a result of bacterial overgrowth and translocation related to alcoholic liver disease and cirrhosis. The resulting bacteremia resulted in the development of infection in the left ankle, which had preexisting disease and was thus vulnerable. This case provides further evidence for the mode of infection being bacteremia in cirrhotic patients. In patients with cirrhosis and fever, a high index of suspicion is required for joint infection as a potential cause of fever or deterioration in the cirrhotic's patient general condition.
