The cartoon in doctor-patient communication. Further study of the Arthritis and Rheumatism Council handbook on gout.

A sample of 50 consecutive patients with gout was tested by means of a multiple-choice knowledge-testing questionnaire based on the Arthritis and Rheumatism Council's Gout: A Handbook for Patients. Patients were divided into two groups: (a) those tested with an illustrated booklet containing 89 cartoons, and (b) those tested with an unillustrated booklet with text exactly the same as in the illustrated booklet. No significant difference was observed in either the overall test scores between the two groups or between individual question scores. It was concluded that increasing the number of illustrations in the Arthritis and Rheumatism Council's handbook on gout had not significantly increased the value of this material as a communication aid. Certain sources of error have been discussed including the possibility of an 'interest factor' due to the inevitable interest patients have in reading about their own disease, and also the possibility that technical factors to do with page layout and picture/text imbalance might be responsible for failing to show differences between the two groups.

Histocompatibility antigens in psoriatic arthritis.

Histocompatibility (HL-A) antigen typing was performed on 82 patients with psoriatic arthritis. The prevalance of HL-AB27 was increased (28%) compared with that in a control group (7-5%), and this was most marked in those with spinal changes. The prevalence in patients with sacroiliitis and syndesmophytes was 75%, with sacroiliitis alone 78%, but with syndesmophytes and normal sacroiliac joints only 36%. The overall prevalence in psoriatic spondylitis was 60%, with a prevalence of 71% in those fulfilling the New York criteria for anklosing spondylitis. The prevalence was not increased in those with only peripheral arthritis (11%). The prevalence of HLA-B13 was decreased in those with psoriatic spondylitis, though this was not statistically significant. The overall prevalence of HLA-BW17 was increased, this being particularly so in those with syndesmophytes, but values were not significant.

Amino acid composition of human nail, as measured by gas-liquid chromatography.

We describe a quantitative method for determination of histidine and 16 other amino acids in a nail hydrolysate. This is based on the formation of trifluoroacetyl amino acid methyl esters and gas-liquid chromatographic analysis with use of two columns of mixed stationary phases. Histidine is determined as a triple derivative Nalpha-trifluroacetyl-Nim-carbethoxy methyl histidinate. The specificity and reproducibility of the method are illustrated. As little as 1 mg of amino acid per gram of nail can be determined, and 15 hydrolysates can be completely analyzed in 10 working days. Data obtained from multiple analyses of 10 nail hydrolysates by the method described closely parallel those obtained in another laboratory, in which an amino acid analyzer was used.
