The results of 93 de la Caffinière thumb joint replacements in 71 patients were reviewed between 6 and 16 years. The survival rate was 89% at 16 years. Eleven thumb joints had failed requiring revision. The commonest reason for failure was aseptic loosening of the trapezial component. The failure rate was higher in men of working age than any other group, which possibly reflects the increased demands on the prosthesis of these patients. We support the use of this implant for degenerative osteoarthritis, but caution against its use in men under 65 years.

85termine the effect of C. nigrum seeds on the serum-free fatty acid and triglyceride fractions.Acute toxicity studies revealed no visible signs and symptoms of toxicity and none of the rabbits had died after 7 days, even at a high dosage like 8 glkg body weight (orally). It is, therefore, hypothesized that the C. nigrum seeds contain one or more types of hypoglycaemic principles. These may include an alkaloid and/or an orally active insulin-like compound. However, production of hypoglycaemia by some other entirely different mechanism cannot be excluded at present. Further comprehensive chemical and pharmacological investigations are thus needed to elucidate the exact mechanism of hypoglycaemic effect and to isolate the active principles of the Abstract: Antiulcerogenic effect of banana have been reported from this laboratory and elsewhere but in none of these communications was the species and variety mentioned. The effects of different biological variables like size (indicating maturity), season and soil on the antiulcerogenic effect of banana have also not been reported. The data of the present study indicate that the antiulcerogenic effect of banana is present primarily in the unripe, green plantain banana obtained from plant Musa sapientum Linn variety paradisiaca. The antiulcerogenic principle in plantain banana appears to be present in big (mature) unripe fruits and varies from season to season and place to place in the Indian subcontinent. The antiulcerogenic principle seems to be thermolabile. Antiulcerogenic effects seems to be due to strengthening of mucosal resistance factors.

Seventy-one patients (93 implants) had a de la Caffinière prosthesis implanted between 1980 and 1989 and were reviewed and reported in 1997. We reviewed this series 10 years later. Similar outcome measures were used as in the original study, pinch and grip strength measured and validated outcome scores obtained (DASH and EQ-5D). Radiographic outcome was assessed. Twenty-six patients with 39 implants were available for review at a mean of 19 years (range, 16-26 years). Survivorship at 26 years was 73.9% (95% CI, 61.2 to 86.6) for re-operation and 26.0% (95% CI, 0 to 52.7) for all failure. Patients had satisfactory power and thumb mobility and continued to be satisfied without pain. Registries should log such prostheses and add to implant survival data.

This study prospectively evaluated the outcome of manipulation under anaesthesia and hydrodilatation as treatments for adhesive capsulitis. A total of 36 patients (38 shoulders) were randomised to receive either method, with all patients being treated in stage II of the disease process. The mean age of the patients was 55.2 years (44 to 70) and the mean duration of symptoms was 33.7 weeks (12 to 76). Eighteen shoulders (17 patients) underwent manipulation under anaesthesia and 20 (19 patients) had hydrodilatation. There were three insulin-dependent diabetics in each group. The mean visual analogue score in the manipulation under anaesthesia group was 5.7 (3 to 8.5; n = 18) before treatment, 4.7 (0 to 8.5; n = 16) at two months (paired t-test p = 0.02), and 2.7 (0 to 9; n = 16) at six months (paired t-test, p = 0.0006). The mean score in the hydrodilatation group was 6.1 (4 to 10; n = 20) before treatment, 2.4 (0 to 8; n = 18) at two months (paired t-test, p = 0.001), and 1.7 (0 to 7; n = 18) at six months (paired t-test, p = 0.0006). The visual analogue scores in the hydrodilatation group were significantly better than in the manipulation under anaesthesia group over the six-month follow-up period (p < 0.0001). The mean Constant score in those manipulated was 36 (26 to 66) before treatment, 58.5 (24 to 90) at two months (paired t-test, p = 0.001) and 59.5 (23 to 85) at six months (paired t-test, p = 0.0006). In the hydrodilatation group it was 28.8 (18 to 55) before treatment, 57.4 (17 to 80) at two months (paired t-test, p = 0.0004) and 65.9 (28 to 92) at six months (paired t-test, p = 0.0005). The Constant scores in the hydrodilatation group were significantly better than in the manipulated group over the six-month period of follow-up (p = 0.02). The range of movement improved in all patients over the six months, but was not significantly different between the groups. At the final follow-up, 94% of patients (17 of 18) were satisfied or very satisfied after hydrodilatation compared with 81% (13 of 16) of those receiving a manipulation. Most of our patients were treated successfully, but those undergoing hydrodilatation did better than those who were manipulated.
