Bioabsorbable implants in orthopaedics: new developments and clinical applications.
The use of bioabsorbable implants in orthopaedic surgical procedures is becoming more frequent. Advances in polymer science have allowed the production of implants with the mechanical strength necessary for such procedures. Bioabsorbable materials have been utilized for the fixation of fractures as well as for soft-tissue fixation. These implants offer the advantages of gradual load transfer to the healing tissue, reduced need for hardware removal, and radiolucency, which facilitates postoperative radiographic evaluation. Reported complications with the use of these materials include sterile sinus tract formation, osteolysis, synovitis, and hypertrophic fibrous encapsulation. Further study is required to determine the clinical situations in which these materials are of most benefit.

The management of pulmonary tuberculosis notified in England and Wales in 1993.
We have compared the management of 925 cases of pulmonary tuberculosis reported to the 1993 national tuberculosis notification survey with the recommended standards of treatment. Forty-eight per cent of patients were white, 36% came from the Indian subcontinent (ISC) and 15% were of other ethnic origin. Most patients (86%) were under the care of thoracic physicians. Sputum microscopy was positive in 44%, and culture confirmation was obtained in 64% of cases. Drug resistance was reported in 30/582 isolates (5%), ranging from 13% in Black-Africans to 4.5% in ISC ethnic groups and 2% in the whites, with none reported in those of Black-Caribbean origin. Almost all patients (94.5%) were started on a recommended drug combination, but only 74% continued to receive one, with thoracic physicians significantly more likely than other physicians to use a recommended combination. Non-standard durations of either initial and/or continuation phase therapy were used in 303 patients, but in only 167 was a satisfactory reason given for the modification. Definite or suspected drug toxicity was reported in 79 (9%) and was significantly more likely with non-standard regimens. Seventy-two patients died before the survey was carried out one year after their notification, only 15 of them directly due to tuberculosis. Of the 815 cases observed to treatment completion, 430 (53%) were then discharged. There were adequate reasons for follow-up after the end of treatment in all but 98 of those so managed. Although the results were satisfactory overall, continued efforts are required to increase the percentage of patients treated with evidence-based recommended regimens and durations of chemotherapy.

The management of lymph node tuberculosis notified in England and Wales in 1993.
We have compared the management of 219 cases of lymph node tuberculosis reported to the 1993 national notification survey with the recommended standards of treatment. The diagnosis was supported by positive histology and bacteriology in 81 cases (37%), positive histology in 70 (32%), positive bacteriology in 26 (12%), and on only clinical grounds in 40 (18%). Most patients (88%) were under the care of thoracic physicians. Almost all (97%) were commenced on a recommended drug combination, but only 81% continued to receive it, with thoracic physicians more likely than other physicians to use a recommended combination. Non-standard durations of the initial and/or continuation phases of treatment were used in 83 patients, but in only 49 cases was a satisfactory reason given for the modification. Definite or suspected drug toxicity was reported in 22 cases (10%), and was significantly more likely with non-standard regimens. There were no deaths. Of the 209 patients observed to treatment completion, 129 (62%) were then discharged. There were adequate reasons for follow-up after the end of treatment in all but 32 (15%) of those so managed. Further education is required to increase the percentage of patients treated with evidence-based regimens and durations of chemotherapy.
