Background And Objectives:
Liver abscess (LA) is a well-described disease in the medical literature; however, information about its characteristics and outcome in the Middle East is lacking. We compared the mode of presentation, risk factors, management and outcome of LA patients in Saudi Arabia with cases from the United Kingdom (UK).
Design And Setting:
Retrospective review of LA patients from three tertiary care centers (2 from Saudi Arabia and 1 from the UK) over a period of 10 years, from 1995 to 2005.
Patients And Methods:
Data collected included demographic characteristics; clinical presentation; biochemical, microbiological and radiological findings; treatment modalities; and outcome.
Results:
A total of 83 patients were diagnosed with LA, including 48 patients from Saudi Arabia and 35 patients from the UK. The mean (SD) age was 45.2 (20.3) years for those from Saudi Arabia and 55.4 (18.8) years for those from the UK (P=.022). The majority of the patients were males (70% from Saudi Arabia and 80% from the UK). Upper abdominal pain and fever were the commonest symptoms, each reported in 87% of the cases. Alkaline phosphatase elevation was the commonest liver function abnormality, seen in 66 (80%) patients. Organisms were isolated in 43 (52%) cases and the majority of these were coliforms (58%). Amebic liver abscesses occurred in 19 (23%) patients and all of those patients were either from or had traveled recently to the Indian subcontinent. Complete resolution of the abscesses was achieved in 66 (80%) patients with aspiration and/or antibiotics, and 9 (10.8%) patients died. On multivariate analysis, underlying malignancy, hypotension and chest signs at presentation were predictors of poor outcome (P=.008, .029 and .001, respectively).
Conclusions:
Successful resolution of LA is achievable in the majority of the cases, although underlying malignancy is associated with poor outcome. Amebic liver abscesses must be considered in patients with a history of travel to endemic areas.

A pleural effusion is the abnormal collection of fluid between the parietal and visceral pleura layers of tissue that form the lining of the lungs and chest cavity. It can occur independently or due to surrounding parenchymal diseases, such as infection, malignancy, or inflammatory conditions.

Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...
