In a prospective study, 38 consecutive cases of primary liver cell carcinoma were seen over one year (1988) at the liver unit of the University College Hospital, Nigeria. An analysis of the chest X-ray findings was made. Normal chest X-rays were found in 23.7% of cases. Abnormal findings included elevated diaphragm (63.2%), pulmonary metastases (18.4%), and pleural effusion (18.4%), perhaps the highest ever so reported. It may be concluded that, in a middle-aged man with a hard irregular hepatomegaly, the findings of the triad of elevated diaphragm, pulmonary metastasis and pleural effusion on chest X-ray should make one very suspicious of liver cancer. The differential diagnoses of these radiological findings are briefly discussed.

Hepatoma is a rare disease in Natal Indians. It occurs in male patients in the fifth decade. They have no history of alcohol intake. The main presenting feature is abdominal pain, weight loss and hepatomegaly. Blood tests reveal a raised alkaline phosphatase, hypoalbuminaemia, hypergammaglobulinaemia and markedly raised gamma glutamyl transferase. The tumour is a single large expanding mass in the right lobe. The patient usually presents in a late stage of the illness and shows a progressive downhill course. Hepatitis B virus infection is emerging as the likeliest carcinogen.

Severe cachexia of extremely rapid onset typifies the young Black African patient with hepatocellular carcinoma (HCC). In order to assess whether this is a consequence of tumor-associated increases in protein metabolism or simply due to inadequate dietary intake, the following study was undertaken. The technique of constant i.v. infusion of 14C-labeled leucine was used to measure whole body protein flux, breakdown, synthesis, and oxidation rates in 8 adults with HCC, 4 patients with massive hepatomegaly due to metastatic adenocarcinoma from bowel, 6 patients with chronic liver disease, and 10 controls. Endogenous protein breakdown and oxidation were similar between patients with chronic liver disease (breakdown, 4.4 +/- 1.2 g/kg/day; oxidation, 0.8 +/- 0.4 g/kg/day) and controls but were significantly (P less than 0.002) higher in patients with liver tumors, the highest rates being observed in those with HCC (breakdown, 8.5 +/- 4.3 g/kg/day; oxidation, 1.4 +/- 0.5 g/kg/day). Protein turnover was generally higher in the HCC group, with increased rates of reincorporation of amino acids into protein synthesis (P less than 0.05). In one HCC patient a synchronized diagnostic liver biopsy demonstrated high fractional synthesis of rates of HCC proteins of 86%/day. In addition, the incorporation rates of labeled amino acid into fibrinogen, immunoglobulin G, and transferrin were also highest (P less than 0.03) in HCC patients. In order to assess the relative importance of diet in weight loss, dietary intake levels were assessed from hospital records of HCC patients and by dietary recall during the week prior to study. Intakes ranged from 30 to 70% of calculated requirement levels. In conclusion, our results suggest that the rapid wasting seen in patients with HCC is due to an imbalance between the metabolic demands, which can be elevated in some patients, and inadequate dietary replenishment.

Immunotherapy with interleukin (IL)-2 possesses great potential in the treatment of immune-mediated diseases and cancers. However, only a few reports on a small number of children have appeared in the literature. From March 1988 to March 1989, 11 children and adolescents were treated with IL-2. They included 1 patient with hepatocellular carcinoma, 1 with hepatoblastoma, 6 with childhood atopic dermatitis, and 3 with juvenile rheumatoid arthritis. The dosages ranged from 10,000 to 50,000 U/kg every 8 hours by intravenous drip. The following side effects were observed: anorexia, fever, and chillness (100%), general malaise (82%), irritability (64%), diarrhea (100%), nausea and vomiting (73%), weight gain (82%), edema (82%), abdominal distension (73%), oliguria (82%), cough (91%), dyspnea (27%), pleural effusion (40%), hypotension (82%), skin eruption (82%), oral ulcer (18%), enlarged liver (73%) liver function abnormalities (82%), renal function impairment (36%), electrolyte imbalance (73%), anemia (91%), thrombocytopenia (54%), leukopenia (18%), and eosinophilia (73%). Immunologically, numbers of natural killer cells were increased and natural killer and lymphokine-activated killer cell activities were augmented after IL-2 treatment. There was a tendency for serum levels of IL-2 and receptor IL-2 to decrease, especially in patients with atopic eczema. Ten patients (91%) completed one course (9 to 12 days) of therapy, and the remaining patient interrupted the treatment because of intolerable adverse effects. Clinically, complete remission for 3 months was obtained in 1 juvenile rheumatoid arthritis patient, transient improvement (2 to 6 weeks) in all atopic dermatitis patients, minor response in the hepatoblastoma patient, and no response in the patient with hepatocellular carcinoma.

The patient, a 29-year-old female, was hospitalized because of clouding of consciousness, fever and right hemiplegia 4 days after the onset. On first examination she was found having fever in the 37 degree range, positive CRP, hepatomegaly, anemia and hepatic function impairment. Neurological examination revealed somnolence, conjugate deviation to the left and stiff neck. The muscular power measured about 3+ for the upper extremities and 0 for the lower extremities. Babinski sign was present on the right side. The spinal fluid showed an increase in cell counts, especially the neutrophil count. CT scans showed diffuse white-matter hypodensity in the left hemisphere. Soon after admission the patient fell into coma and died 6 days after admission. Autopsies led to a diagnosis of Hurst's encephalitis complicated by hepatoma with liver cirrhosis. It was reported that the immune complex was found in 25.9% of liver cirrhosis patients. From this fact it is suggested that Hurst's encephalitis might be elicited by some immunological mechanism.

A case of a solitary symptomatic non-parasitic cyst of the liver, was seen and treated at the Muhimbili Medical Centre, Dar Es Salaam. This is the first case report from Tanzania, cystic disease of the liver is rarely diagnosed clinically, the possibility should be seriously considered in any patient with an enlarged liver which is associated with few or no symptoms and little or no impairment of liver function. In African countries, it is suggested that non-parasitic cysts of the liver be considered in the differential diagnosis of hepatocellular carcinoma because of its high prevalence rate in these countries.

Three patients with hereditary tyrosinemia type 1, two brothers and one girl, studied at the age of 5, 12 and 15 years, respectively, had neither generalized hyperaminoaciduria, glucosuria nor clinical symptoms of rickets. Untreated the elder brother had only slightly elevated plasma tyrosine level (141 mumol/l, normal less than 80), and low excretion of p-hydroxyphenyllactate. He presented with pronounced thrombocytopenia (3 X 10(9)/l). At 13 years of age he contracted hepatocellular carcinoma. The younger brother presented with serum tyrosine of 318 mumol/l and thrombocyte count 48 X 10(9)/l. Succinylacetone in urine was elevated in both, 30 and 79 mumol/mmol creatinine, respectively. The female patient was investigated for hepatomegaly in infancy, atypical tyrosinemia being considered, but afterwards developed normally without diet or any other treatment until she contracted hepatoma at the age of 15 years. Her plasma tyrosine level was 600-700 mumol/l, and she excreted large amounts of p-hydroxyphenyllactate. Succinylacetone in urine was low but elevated (8 mumol/mmol creatinine). The fumarylacetoacetase activity in fibroblasts from the brothers and in lymphocytes from the girl was less than 5% and 10% of control levels, respectively. In conclusion, the chronic form of hereditary tyrosinemia may occur without evidence of renal tubular dysfunction.

Differential effects of total parenteral nutrition (TPN) on host nutrition and growth of cancer are unclear. Growth of adult ACI-N rats bearing transplanted Morris hepatocarcinoma no. 3924A given TPN with or without fat was studied in comparison with Purina Chow-fed, fasting, and semifasting (either amino acid or dextrose alone) rats over 5 days. The isocaloric, isonitrogenous TPN regimens with or without fat maintained body weight and nitrogen balance of cancer-bearing rats equally well. When compared with Chow-fed rats, the volume of the cancer, its weight, doubling time, protein content, and incorporation of thymidine into DNA were similar in rats given TPN either with or without fat. Although the volume of the cancer decreased in fasting and semifasting rats, the nutritional status of the host was also impaired. Administration of TPN to cancer-bearing rats was associated with an abnormal increase in serum lactic acid level, which was not ameliorated by the use of fat to reduce the carbohydrate load. Although TPN with and without fat maintains the nutritional status, hepatomegaly and hepatic steatosis limit the administration of carbohydrate and fat as energy substrates in this system.

Clinical, laboratory, and ultrasonographic features of 75 patients of primary hepatocellular carcinoma (PHC) living in the Gizan Area of Saudi Arabia and their follow-up, during a 2-year period, were characterized. Eighty-nine percent of the cases were defined histologically, whereas in the rest, ultrasonographic (US) evidence along with an alphafetoprotein (AFP) level exceeding 480 ng/ml were taken as the positive evidence for PHC. Eighty percent of the cases were male patients, with the peak incidence during the seventh decade. The most common clinical presentations were hepatic enlargement (91%), abdominal pain (76%), splenic enlargement (33%), and acites (33%), followed by bruit, fever, metastases, and varices. Alteration in a liver function test was manifest in 97% of the cases, AFP values greater than 480 ng/ml in 57%, and a hepatitis B virus surface antigen (HBsAg) positivity in 65% of the cases. There was no intersex variation in positivity for HBsAg, antibody to HBsAg (anti-HBs), antibody to hepatitis B virus core antigen (anti-HBc) among the 30 PHC cases studied. Positivity for HBsAg or the overall hepatitis B virus exposure in PHC cases was higher than the normal controls (P less than 0.001). In addition to histologic confirmation of PHC in 67 cases, there was histologic evidence of cirrhosis in 25%, or chronic active hepatitis in 19% of the cases. At the time of diagnosis, the average duration of the presenting illness was less than 2 months, while the mortality in the ensuing 2-month period was 73%. The average span of total illness in the vast majority of cases was 4 to 6 months. Two female patients (one with fibrolamellar carcinoma) however, survived for 2 years. Immunization against hepatitis B virus should be considered for all newborns in such hyperendemic communities. A continuous program should be started in such communities to screen and immunize all those yet unexposed to hepatitis B virus. The established HBsAg carriers should be periodically examined ultrasonographically along with an AFP estimation for initiating the chemotherapeutic and other measures against PHC in fairly early stages of malignancy.

The purpose of this study is to evaluate the appropriateness of laparoscopic examination in Ethiopia where chronic liver diseases and tuberculous peritonitis commonly present with ascites. A total of 240 patients were examined consecutively. The indications were ascites (62%) hepatomegaly (29%), splenomegaly (22%), oesophageal varices (31%), abdominal masses (6%) and miscellaneous conditions (5%). Laparoscopic findings included cirrhosis with or without primary hepatocellular carcinoma (PHC) in 72% and tuberculous peritonitis in 6% of 232 successfully examined cases. Biopsies were possible in 165 cases. When all 144 patients with ascites were separately analyzed, 82% were due to cirrhosis of the liver with or without PHC and 9% tuberculous peritonitis. There was a good correlation between laparoscopic and histological diagnosis. Though invasive, the procedure carries low morbidity and the diagnostic yield is high. The laparoscope, therefore, should be considered as an appropriate technology for developing countries.
