The causes of abdominal pain in patients with AIDS are different from those of the general population, and there are no guidelines as to which investigations are optimal. We reviewed our experience of 63 patients who presented with abdominal pain as the main reason for admission to the AIDS unit at St Stephen's and Westminster Hospital between January 1988 and January 1990. All patients were assessed within the same structured diagnostic programme. Thirty-five had upper abdominal pain, predominantly in the right upper quadrant in 27; seven had lower abdominal pain, which was concentrated in the right iliac fossa in three; 21 had diffuse abdominal pain. The causes of pain were determined satisfactorily in the majority of patients using routine gastroenterological investigations. The predominant site of pain had considerable predictive value in the diagnosis. The commonest cause of right upper quadrant pain was sclerosing cholangitis (17 of 27); endoscopic retrograde cholangio-pancreatography was necessary for a confident diagnosis. Diarrhoea was frequently associated (15 of 21) with diffuse abdominal pain; the commonest cause (six of 21) was cytomegalovirus colitis. Neoplasia was the cause of abdominal pain in eight patients. The other causes of abdominal pain and the utility of various investigations are discussed. An investigatory route which may provide maximum information has been suggested.

The medical records of 222 patients with liver abscess at Siriraj Hospital from 1978 to 1985 were analysed. Amoebic abscess was three times more prevalent than pyogenic abscess. In both groups middle aged males were affected more often than others. The main clinical manifestations were fever, right upper quadrant pain and hepatomegaly. History of colitis in the past, marked leukocytosis, elevation of alkaline phosphatase and a single abscess confined to the right lobe were suggestive of amoebic liver abscess. The presence of concurrent abdominal infection, marked anemia and jaundice were associated with pyogenic abscess. Patients with pyogenic abscess developed complications more often and the case fatality rate was greater than patients with amoebic abscess. Most of the patients were successfully treated with a combination of antimicrobials and drainage.

Amebiasis can be considered the most aggressive disease of the human intestine, responsible in its invasive form for clinical syndromes, ranging from the classic dysentery of acute colitis to extra-intestinal disease, with emphasis on hepatic amebiasis, unsuitably named amebic liver abscess. Found worldwide, with a high incidence in India, tropical regions of Africa, Mexico and other areas of Central America, it has been frequently reported in Amazonia. The trophozoite reaches the liver through the portal system, provoking enzymatic focal necrosis of hepatocytes and multiple micro-abscesses that coalesce to develop a single lesion whose central cavity contains a homogeneous thick liquid, with typically reddish brown and yellow color similar to "anchovy paste". Right upper quadrant pain, fever and hepatomegaly are the predominant symptoms of hepatic amebiasis. Jaundice is reported in cases with multiple lesions or a very large abscess, and it affects the prognosis adversely. Besides chest radiography, ultrasonography and computerized tomography have brought remarkable contributions to the diagnosis of hepatic abscesses. The conclusive diagnosis is made however by the finding of Entamoeba histolytica trophozoites in the pus and by the detection of serum antibodies to the amoeba. During the evolution of hepatic amebiasis, in spite of the availability of highly effective drugs, some important complications may occur with regularity and are a result of local perforation with extension into the pleural and pericardium cavities, causing pulmonary abscesses and purulent pericarditis, respectively The ruptures into the abdominal cavity may lead to subphrenic abscesses and peritonitis. The treatment of hepatic amebiasis is made by medical therapy, with metronidazole as the initial drug, followed by a luminal amebicide. In patients with large abscesses, showing signs of imminent rupture, and especially those who do not respond to medical treatment, a percutaneous drainage must be performed with either ultrasound or computerized tomography guidance. Surgical drainage by laparotomy is reserved to patients with secondary infections.

Preeclampsia and the variant HELLP syndrome are systemic conditions associated with vascular changes resulting in vasoconstriction. Most commonly, patients present with elevated blood pressure and proteinuria, with a background of complaints such as headache, scotoma, and right upper quadrant pain. The systemic vascular changes experienced can target any organ system, oftentimes with more than one organ system being involved. We present the case of a patient admitted with HELLP syndrome who subsequently developed multisystem organ dysfunction, including placental abruption, disseminated intravascular coagulopathy, acute renal failure, colitis, abdominal ascites, pancreatitis, and the development of pancreatic and colonic abscesses.
