Hypercholesterolaemic arthropathy in primary biliary cirrhosis.

A new cause of severe transient fitting polyarthritis is described in a patient with primary biliary cirrhosis. Hypercholesterolaemia is thought to provoke acute inflammatory periarthritis and peritendinitis. The clinical features are sudden onset of peripheral joint pain and effusion, with redness of the overlying skin, often precipitated by unusual exercise. Cholestyramine may help to prevent this form of arthritis.

Hepatocellular carcinoma in primary biliary cirrhosis: report of four cases.

Of 98 patients dying with primary biliary cirrhosis only four developed hepatocellular carcinoma. It is suggested that the development of hepatocellular carcinoma is uncommon in this type of chronic liver disease because of its known female preponderance, and the fact that cirrhosis develops late in the course of the illness.

Hepatitis Bs antibody in alcoholic cirrhosis.

Sera from patients with chronic liver disease were tested for antibody against hepatitis B surface antigen by radioimmunoassay. The antibody was found in 25% of patients with alcoholic cirrhosis and in 52% when alcoholic cirrhosis was associated with portal hypertension, these results being significantly higher than in a matched control population. Other forms of chronic liver disease did not differ from the control population. Hepatitis B virus infection might be a factor in determining which alcoholic patients go on to develop chronic liver disease and cirrhosis.

The danger of hallucinogenic mushrooms.

There has been a revival of interest amongst young people in the raw consumption of "wild" Psilocybin mushrooms, because of their hallucinogenic properties. Seven cases of mushroom overdosage are described. Whilst the hallucinogenic mushrooms are relatively harmless, the dangers from inadvertent ingestion of commonly occurring poisonous varieties are emphasised.

The value of the 14C breath test in the assessment of fat absorption.

The absorption of oral 14C-glyceryl tripalmitate was tested in 77 subjects by hourly interval sampling of breath 14CO2 for up to 6 h. A highly significant correlation was obtained between maximum breath 14CO2 activity and faecal fat excretion. The test was very effective in differentiating between patients with and without steatorrhoea. Repetition of this examination with oral 14C-palmitic acid demonstrated normal absorption in pancreatic steatorrhoea but impaired absorption in intestinal steatorrhoea, thus enabling these conditions to be distinguished. The 14C breath tests are most useful as simple and inexpensive outpatient screening tests for steatorrhoea.

Reduction in peripheral blood K cells and activated T cells in primary biliary cirrhosis.

Lymphocyte subpopulations were measured in the peripheral blood of 13 patients with primary biliary cirrhosis (PBC), 13 with chronic active hepatitis (CAH), and 16 age- and sex-matched normal subjects. A significant, relative and absolute, reduction in activated T cells and K cells, compared with that in normal subjects, was found in PBC but not in CAH. The reduction in K cells observed in PBC was found to be accompanied by a parallel decrease in lymphocyte-mediated antibody-dependent cytotoxicity.

Computer interrogation of patients.

A system of routine interrogation of patients using a computer has been developed. It includes a visual display unit with a specially designed response keyboard, and the program has been designed to adapt to the individual patient. The system was evaluated objectively, using the criteria of accuracy in eliciting symptoms, acceptability to the patient, and cost. While doctors will always take the ultimate management decisions, it seems that machines can be programmed to undertake the routine interrogation of patients, elicit evidence accurately and acceptably, and calculate the probabilities of disease as effectively as doctors.

The management of ulcerative colitis.

The modern medical and surgical treatment of ulcerative colitis has been detailed. Whilst improvements in medical management have been few in the past decade there have been advances in dietary management and in the use of new drugs such as azathioprine and disodium cromoglycate which are currently being evaluated. Sulphasalazine remains a valuable drug in treating attacks of the disease and in preventing relapses, and its mode of action is now better understood. Steroid therapy, used orally, parenterally or topically, is of value in managing acute colitic attacks. Surgery is often required and total proctocolectomy with ileostomy remains the operation of choice. Colectomy with ileorectal anastomosis still remains a controversial operation but has its enthusiastic advocates. The interesting a new operation of proctocolectomy, with the establishment of an ileal bladder and continent ileostomy, is being assessed in Sweden and in a few centres in Britain and America.
