Changes of the modal frequencies after delamination initiation, compared to those of a non-delaminated specimen, gave a good indication of the degree of damage, demonstrating the feasibility of using measured changes in the vibration characteristics to detect damage.
At the time of spacer removal, a single intraoperative specimen gave a positive culture result in two patients (coagulase-negative bacteria in both cases), without pre-operative signs of infection.
Furthermore, scanning electron microscopy (SEM) of the fractured specimens gave an insight into the change in dimple size and the presence of quasi-brittle islands which were a direct consequence of the various active deformation mechanisms.
Analysis of 273 particles selected from 10 images of freeze-dried, unstained NECD specimens gave an average molecular mass of 381±23 kDa, and fitting of the particle mass histogram with a Gaussian curve gave a peak value of 412 kDa (Figure 2C).
Imprint cytology of the biopsy specimens gave an additional positive result in 109 cases (7.9%).
The study demonstrated that the analysis of a cumulative area of 2.5 mm2 from at least three biopsy specimens gave an accurate estimate of the overall joint.
Each well contained 700 µl of Middlebrooke 7H9 broth, 100 µl of a cocktail of polymyxin B, Amphotericin B, Nalidixic acid, trimethoprim and azlocillin (PANTA: BD®), 100 µL of solutions of INH 1 µg/ml or RIF 10 µg/ml and 100 µl of the processed specimen, giving a final volume of 1 ml/well, and critical concentrations of 0.1 µg/ml INH and 1 µg/ml RIF.
Eighteen photographs were obtained from each specimen, giving a total of 900.
The results showed that the residual soil specimens gave a relatively consistent equilibrium time (roughly 8 min).
On average, papers that looked at myomectomy specimens gave a lower risk of sarcomatous change of 0.08 % (1 in 1,306) compared to those that looked at hysterectomy specimens where the overall pooled risk was 0.15 % (1 in 650).
