The incidence of primary liver cell carcinoma was investigated in a prospective study over 6 yr and 5 mo in 403 clinically unselected patients derived from a homogeneous population by means of serial determination of alpha 1-fetoprotein (AFP) by radioimmunoassay. The diagnosis of liver cirrhosis was proved in 90% by laparoscopy and/or histology and/or autopsy. The incidence of primary liver cell carcinoma in liver cirrhosis in the clinically studied patients was 4.47%, significantly lower than in the autopsy material (11.03%; p less than or equal to 0.025). In the follow-up study, all patients with increasing AFP concentrations exhibited a primary liver cell carcinoma. A transitory rise of AFP (higher than 50 ng/ml) was observed in 15.1% of patients with liver cirrhosis without primary liver cell cancer. In contrast to the results of animal experiments, this transitory rise of AFP was not followed by malignant transformation of the cirrhotic tissue. Posthepatitic liver cirrhosis was observed in 21.57%, postalcoholic liver cirrhosis in 42.93%, and cryptogenic liver cirrhosis in 27.30%. Liver cirrhosis of other etiology occurred in 8.19%. The incidences of primary liver cell cancer in these 4 groups were 4.94, 4.62, 5.45, and 0%, respectively. These differences are not statistically significant, although in absolute figures postalcoholic liver cirrhosis is the main cause of primary liver cell carcinoma in this sample from West Germany. HBs antigen-positive liver cirrhosis was more often associated with primary liver cell cancer than HBs antigen-negative liver cirrhosis (6.58 versus 3.96%); this difference also is not statistically significant. Observations of larger groups of patients may show a higher risk of developing primary liver cell carcinoma in those with a combination of alcohol abuse and HBs antigenemia and/or acute hepatitis in the history. Patients without these 2 risk factors had an incidence of primary liver cell carcinoma of 2.61%; those with 1 risk factor, 5.77%; and those with both risk factors, 10.71%.

Necropsies were performed on 285 consecutively unclaimed Orang Asli bodies from Gombak Orang Asli Hospital during an eight-year period from May 1967 to April 1975. Of the 25 malignant neoplasms, hepatocellular carcinoma was by far the commonest (36%). The nine patients with this neoplasm had coexistant macronodular cirrhosis. There were 20 cases of cirrhosis; 45% of these had coexistant hepatocellular carcinoma. The 53,000 Orang Aslis living in West Malaysia comprise three tribes, the Negrito, Senoi, and Melayu Asli (Proto Malays). The Sinoi appear to have a high predilection for liver cancer, all our nine cases occurring in this group. These aboriginal people live in the jungles where they practice shifting cultivation and maintain their own dietary and social customs. Detailed studies of their dietary habits may provide a clue to the etiology of liver cancer in these people.

Fifty-five hepatocarcinomas were found in a review of approximately 7,500 surgical biopsies done on Nigerian Igbos during a period of 6 years. The male: female ratio was 2.9:1 and the age peak was between 20 and 49 years. The main symptoms were abdominal swelling, pain, emaciation, jaundice, fever, anorexia and diarrhea. Physical examination revealed a palpable liver in nearly all patients. Two patients presented acutely with hemoperitoneum due to rupture of necrotic tumor nodule. Cirrhosis was found in 60% of the adequately sized specimens. In comparison with published data, this series from an ethnic group in Nigeria, West Africa, reveals both similarities and dissimilarities which are noteworthy.

In patients who have impaired hepatic reserve, the Warren shunt has been proposed as an effective operation because it decompresses the esophageal varices without disturbing portal perfusion of the liver. However, early reports of high operative mortality and technical difficulties have impeded acceptance of the procedure. The operation was done in a series of 17 patients. All patients in whom elective variceal decompression with a patent splenic vein was required and without clinical ascites were candidates for this operation. Follow-up ranged from 2 to 48 months. Six patients had alcoholic cirrhosis, two had primary biliary cirrhosis and seven had postnecrotic cirrhosis; in two the cause of the liver disease was unknown. Five patients were categorized as Child's class A, nine as class B and three as class C. No intraoperative or early postoperative deaths owing to hemorrhage occurred. However, there was one death two weeks postoperatively from pulmonary sepsis and one death five weeks postoperatively due to antigen-positive hepatitis. Two patients died from hepatic failure six weeks and five months after operation, respectively; in the first of these, chronic active hepatitis was diagnosed at the time of operation. In one patient hemorrhage recurred and transfusion was required. Although ascites, which eventually resolved, developed in eight patients after operation, the results in 76 percent of patients have been good without new episodes of hemorrhage or encephalopathy. We conclude that the Warren shunt is a safe and effective elective operation for the treatment of patients in whom hemorrhage from esophageal varices has occurred.

Pigment gallstones are defined as any dark brown-to-black stone, consisting of calcium salts of bilirubin, phosphate, carbonate and other anions, and can be separated into carbonate- and noncarbonate-containing groups. Pigment stones predominate in the rural Orient, in cirrhosis, and in elderly United States patients undergoing cholecystectomy. Clinical associations include bile duct obstruction, stasis, and possibly hemolysis. Of pigment stones, 50% are radioopaque and account for two-thirds of all opaque stones. The concentrations of bile salts, phospholipids,, cholesterol, and total bilirubin in bile are similar to normal levels, but the concentration of unconjugated bilirubin is increased in the bile of some patients. Increased unconjugated bilirubin in bile may be caused by increased hydrolysis of excreted conjugated bilirubin. Unconjugated bilirubin is solubilized by bile salts, but the interaction is primarily nonmicellar. Ionized calcium and pH are important determinants of solubility. Sulfated glycoproteins, excreted in increased amounts in patients with cholelithiasis, may be the site of pigment stone precipitation because these compounds bind calcium salts tightly. E coli is frequently cultured from pigment stones in Japan but not in the United States; thus, bacterial beta-glucuronidase may be important in stone formation in Japan but probably not in the West. Stasis leads to increased calcium secretion and to increases in the concentration of sparingly soluble compounds that may then precipitate. Incomplete emptying of the gallbladder may result in the same concentration process. Unsaturated fats and chronic vagal stimulation cause pigment stone formation in animals. At present, surgery is the only treatment for pigment lithiasis.

The relative sensitivities of counterimmunoelectrophoresis (CIE) and haemagglutination assays for the detection of hepatitis B surface antigen (HB(s)Ag) and antibodies (anti-HB(s)) were compared. Twelve scientists from ten countries in Asia, Africa and the Pacific region participated in the study. The participants provided serum samples from 15 953 subjects comprising patients with acute and chronic hepatitis, cirrhosis, and hepatocellular carcinoma (HCC), as well as blood donors and other normal individuals. For the detection of HB(s)Ag in a reference panel serum, immune adherence haemagglutination (IAHA) was slightly more sensitive than passive haemagglutination inhibition (PHI); CIE was the least sensitive. Mean HB(s)Ag frequencies in patients with acute hepatitis, chronic hepatitis, cirrhosis, and HCC were significantly higher than in healthy controls. Passive haemagglutination (PHA) was more sensitive than CIE for the detection of anti-HB(s). The frequency of anti-HB(s) in patients with HCC was significantly lower than that in the other groups. Mean anti-HB(s) frequencies in patients with acute hepatitis, chronic hepatitis, and cirrhosis were not significantly different from that in normal subjects. Subtyping of HB(s)Ag was performed by PHI. Among asymptomatic carriers the predominant HB(s)Ag subtype in northeast Asia was adr.In India, ayw predominated in carriers, with the demarcation between adr and ayw occurring west of Burma. In West Africa the only subtype detected was ayw, but in East Africa the majority subtype was adw. The r subtype was found only in Asian populations east of India and in Western Pacific populations. In Papua New Guinea all four subtypes were identified. With one possible exception, the subtypes of HB(s)Ag-positive patients with liver disease reflected the predominant type in each geographic location.

Causes of death in 8 of 235 drunkenness offenders each followed up for two years, have been described. The subjects followed up were a heterogenous population of alcohol abusers. The majority were alcohol dependent irregular heavy drinkers. The main causes of death were suicide, road traffic accident, domestic accident, liver cirrhosis, hypothermia (from exposure) and ischaemic heart disease. More than one cause of death was listed in all cases. Chronic alcoholism was frequently listed. Depression was another sub-ordinate cause of death. The overall observed rate of mortality was 30 times the expected rate which was many times higher than those reported by earlier workers for alcoholics generally. These findings were discussed and it was concluded that drunkenness offenders are a particular at risk sub group of alcoholics. In view of the appreciable post mortem blood alcohol levels, it was further concluded that chronic alcoholism and the actual state of being drunk were the two major causes of death in this group of alcohol abusers.

Ninety-five cases of typhoid infection seen at autopsy at the University College Hospital, Ibadan, over a 10-year period were reviewed. They constituted 2.7% of 3,556 autopsies performed during this period. Apart from the associated conditions such as sickle cell disease, aplastic anaemia, schistosomiasis, liver cirrhosis and pregnancy which may lower the patients' immunity, a delay in seeking medical care, misdiagnoses, inappropriate therapy and a high complication rate were some of the factors that would appear to contribute to mortality. Therefore, in order to reduce death associated with these factors, it is essential to improve the health education of the people stressing the importance of personal communal hygiene and prompt hospital attendance from the onset of illness. There must also be improved clinical awareness of the disease to ensure early diagnosis and treatment. These are of great importance as the disease is treatable.

The fact that only a small percentage of excessive drinkers develop cirrhosis may be due to a genetic susceptibility to the disease. In order to identify possible genetic risk factors for cirrhosis, we studied mixed-race (Negroid-Caucasian) inhabitants of the French West Indies and compared: (1) the frequency of 51 HLA-A, -B, -C and -DR antigens in 41 subjects with alcoholic cirrhosis and in two control groups consisting of 41 excessive drinkers free of liver disease and 51 healthy non-drinkers; and (2) the frequency of Gm and Km haplotypes in the same groups. Analysis of the Gm system also determined the patients' ethnic origins. The frequency of the HLA-A2 antigen was significantly higher in the cirrhotic patients than in the control group of excessive drinkers (chi 2 = 4.47; P less than 0.05), while that of the HLA-B15 antigen was significantly lower (chi 2 = 5.14; P less than 0.05). The frequency of the Cw4 antigen was significantly higher in the cirrhotics than in the non-drinkers (chi 2 = 5.59; P less than 0.05). However, these differences did not persist when the number of comparisons was taken into account. The frequency of Gm and Km haplotypes was not significantly different in the three groups. In conclusion, complementary studies are required to determine the value of the Gm-Km system as a marker of susceptibility to alcoholic cirrhosis. Our results do not identify an association between HLA antigens and cirrhosis specific to a negroid ethnic group and support the notion that such an association is weak.

The study was designed to determine the prevalence of alcoholism/problem drinking among emergency medical admissions. Of 203 emergency admissions to two medical wards, 18% were found to be problem drinkers, using the brief Michigan alcoholic screening test (MAST) questionnaire. Problem drinking was found in 31% of males and 5% of females. Most drinking was done with friends (77%) and at the "rum shop" (62%). Fifty-one per cent of problem drinkers started between the ages of sixteen and twenty years. Seventy per cent of all problem drinkers had a first degree family relative who drank compared to 28% of non-drinkers. A high prevalence of alcoholism (48%) was found among smokers. Housestaff detected just over half of male (56%) and female (60%) alcoholics who were MAST-positive. Medical diagnoses among MAST-positive patients were gastrointestinal (cirrhosis, pancreatitis and hepatitis) in 32%, neurological (delirium tremens, seizures and subdural hematoma) in 27% and cardiovascular (cardiomyopathy, heart failure and dysrhythmias) in 16%. The detected level of problem drinking is likely to cause significant morbidity, and allows an important opportunity for intervention. The use of questionnaire methods to screen for alcoholism needs further evaluation in the region.
