The chief causes of liver disease in Ethiopia are reviewed, considering hospital data on admissions for hepatitis, cirrhosis, ascites and hepatoma. Liver diseases account for 11.4% of all medical admissions in 3 medical wards in Addis Ababa. The causes are viral hepatitis, post- hepatic and post necrotic and mixed cirrhosis and hepatocellular carcinoma. Alcoholic cirrhosis is rare. Viral hepatitis with shivering, rigor and fever and elevated direct bilirubin levels are common in Ethiopians, especially in child-bearing women. The hepatitis B surface antigen (HBsAg) is often associated with hepatitis. The disease may be transmitted by several species of mosquitoes, placental transmission, or feces, urine, saliva or semen. Blood products are not screened for hepatitis B. Cirrhosis is common, and causes significant mortality, usually from esophageal varices and hepatic coma. Chronic active hepatitis patients may live for a time, especially if they are near a hospital and are treated with steroids. In Ethiopia presenting symptoms for hepatoma are anorexia, weight loss, persistent, burning, right upper quadrant pain, and a hard, nodular, tender RUQ mass. Over 5% of malignancies seen are primary hepatocellular carcinomas. 50% have HBsAG, compared to 3.8% of controls. 65% have alpha-fetoglobulins. It is suggested that some viral hepatitis cases progress to cirrhosis, of which some go on to hepatocellular carcinoma. Herbal medicines, aflatoxins and other toxins may also contribute to liver disease.

Ultrasound examinations of 563 patients with right upper quadrant pain and a clinical suspicion of acute cholecystitis were reviewed. In 31 patients, a tender, dilated gall-bladder with a thick (more than 4 mm) partly hypoechoic wall without any detectable calculi was found on the emergency examination. This was interpreted as due to acute acalculous cholecystitis. None of the patients was critically ill. Twenty-one of the patients had follow-up studies with either oral cholecystography, cholangiography, or ultrasound. Fourteen of the 21 had gall-bladder calculi while seven did not. These seven patients presumably represent the true frequency (1.2%) of acute acalculous cholecystitis in this clinical setting. In five other patients with an initial diagnosis of acute acalculous cholecystitis the gall-bladder wall thickening probably was secondary to concomitant pancreatitis, appendicitis, hepatitis or peptic ulcer disease. A meticulous and careful search for gall-bladder calculi should be performed in the presence of a dilated, tender thick-walled gall-bladder.

Clinical and laboratory evidence of an association of oral contraceptive (OC) use with the subsequent development of benign and malignant hepatobiliary neoplasia is growing. The authors present a case in which an adenoma within a large, multicentric anaplastic spindle cell carcinoma occurred in a woman with a long history of OC use. The patient, a 38-year-old gravida 2, para 2, was diagnosed following low-grade fevers and right upper quadrant pain. A partial hepatectomy was performed with no complications; however, a follow-up examination 2 months later revealed widespread intra-abdominal tumor recurrence histologically identical to the original tumor. Immunostaining for alpha 1 antitrypsin and keratin was strongly positive in tumor cells, indicating a biliary derivation. Electron microscopy indicated an epithelial derivation as well, including the presence of intracellular lumens, intermediary filaments, and numerous intercellular junctions. Estrogen and progesterone receptors were negative in the tumor. The tritiated thymidine labeling index was 5.05%, with an estimated potential doubling time of 11 days. This woman had no history of hepatitis, no family or personal history of neoplasms, and no known hepatotoxin exposure. The only medication used by the patient was Norlestrin, an OC containing 1 mg norethindrone and 50 mcg ethinyl estradiol that she had taken continuously for the past 8 years.

Differential diagnosis of viral hepatitis begins with a check for darkened urine and bile in the urine. These hallmarks of conjugated hyperbilirubinemia immediately rule out prehepatic liver disease. Next, studies are done for the elevated transaminase levels that are characteristic of hepatitis infection, and a thorough history is taken to rule out drug- and toxin-induced hepatitis that may mimic acute viral hepatitis. Elevated alkaline phosphatase is a good marker of cholestasis. Ultrasonography can clarify this diagnosis. The classic presenting symptoms of viral hepatitis are jaundice, nausea, vomiting, malaise, anorexia, and dull right upper quadrant pain. However, serologic studies are needed to detect the presence of specific viral agents.

A patient with right upper quadrant pain showed normal tracer extraction and a prolonged hepatocellular phase during biliary imaging, findings that are most consistent with complete common duct obstruction. He had no other evidence of biliary tract obstruction and was diagnosed subsequently as having viral hepatitis. Hepatitis must be considered when biliary imaging suggests complete common bile duct obstruction.

Cytomegalovirus-induced hepatitis presented as acute right upper quadrant pain with a cholestatic profile in a middle-aged woman. The presentation was confused by the presence of gallstones. Her course was complicated by pleuritis, atypical lymphocytosis, lymphadenopathy, and transient arthritis. Urine virus cultures grew cytomegalovirus and seroconversion of indirect immunofluorescent antibody to late cytomegalovirus antigen was demonstrated. Biopsies of the patient's liver failed to grow cytomegalovirus or to show viral inclusions. Electron micrographic studies were negative. Biopsy specimens were stained with monoclonal antibodies to cytomegalovirus by an indirect fluorescence technique. Clearly defined inclusions were specifically stained. Both nuclear and cytoplasmic inclusions were demonstrated using monoclonal antibodies CH16 and CH12, respectively. Insofar as we are aware, this is the first reported direct evidence for hepatic viral infection with this virus in a previously healthy adult.

Two cases of unusual extrapulmonary tuberculosis are presented. One patient was suffering of a pulmonary tuberculosis involving the brain, liver, spleen and peritoneum, with headaches, ascites, weight loss and night sweats. The other patient had lymph nodes and nodular liver tuberculosis and complained of fever, right upper quadrant pain, anorexia and weight loss. This tuberculosis form is extremely rare; only 23 cases were reported between 1950 and 1990. Furthermore, a drug-induced hepatitis developed in a liver already damaged by the tuberculosis and a chronic active C hepatitis. These two cases remind us that the diagnosis of extrapulmonary tuberculosis may be extremely difficult. It must be suspected mostly in patients that are immuno-depressed or whose origins are not caucasian. Other diagnoses are often wrongly suggested, such as tumors, inflammatory diseases or other infectious diseases. As a result, the correct diagnosis or other infectious diseases. As a result, the correct diagnosis is often delayed. If cultures are negative and the chest roentgenogram is normal, procedures such as transbronchial, liver, bone marrow or lymph node biopsies may help to properly identify the disease.

Epstein-Barr (EB) virus infection is common, with up to 90% of individuals demonstrating positive titers by age 20. Although elevated liver function tests commonly occur, severe hepatitis is rare. Only six cases of ascites complicating Epstein-Barr infection are reported, but none clearly demonstrate the absence of other causes of hepatic dysfunction. A 37-yr-old male presented with a 4-wk history of upper respiratory tract symptoms. Over 3 days before admission he developed jaundice and right upper quadrant pain. After hospitalization, the patient developed tense ascites requiring paracentesis. Serum-ascitic albumin gradient was 0.3 g/dL. Liver function tests peaked at the following values: prothrombin time of 24.5 s, total bilirubin of 18.0 mg/dL, and transaminases in excess of 5000 IU/L. EB Virus IgG and IgM titers were 1:640 and >1:40, respectively. Other viral serologies and polymerase chain reactions were negative. The patient experienced a complete clinical and laboratory recovery over the next 6 months. This represents the first documentation of ascites complicating Epstein-Barr infection without other sources of hepatic dysfunction. It demonstrates a narrow serum-ascitic albumin gradient in these patients, and that complete recovery can occur with supportive care.

Azithromycin (Zithromax), an erythromycin derivative that belongs to a subgroup of the macrolides known as azolides, has generally been considered to be a very safe medication. Hepatic side effects are uncommon but may include jaundice, fever, and right upper quadrant pain. Herein we describe a patient who developed azithromycin-induced cholestatic hepatitis that resolved upon discontinuation of the drug. Lack of other known causes for liver disease, the temporal relationship with this drug, and the typical changes of liver histology have established the diagnosis. Clinicians should be aware of this side effect of azithromycin, which is widely prescribed.

Fitz-Hugh-Curtis syndrome (FHCS) is a condition with right upper quadrant pain in association with pelvic inflammatory disease. Invasive procedures such as laparoscopy or laparotomy were indispensable to definite diagnosis of FHCS, and no more useful methods in radiological diagnosis of FHCS has been reported until now. In this present study abdominal enhanced-CT findings were analysed retrospectively in eight cases diagnosed clinically as FHCS. We focused on hepatic capsular enhancement, which was identified on early phase in all cases and on delayed phase in five. Moreover, hepatic capsular enhancement was detected at the anterior surface of medial segment and the lateral aspect of right lobe in all cases, while at the anterior surface of lateral segment in five cases. These findings, which disappeared on follow-up CT after treatment, were thought to reflect "acute" peri-hepatitis. Abdominal enhanced CT, especially on early phase, is suggested to be a non-invasive, useful modality for the diagnosis of FHCS. When hepatic capsular enhancement is identified in the interpretation of abdominal enhanced CT images in sexually active women who have right upper abdominal pain, we should suspect the possibility of FHCS and examine gynecological findings or the value of IgA and IgG antibodies for Chlamydia trachomatis.
