Abstract

PURPOSE: Developmental dysplasia of the hip (DDH) is a term used to cover a broad spectrum of anomalies ranging from mild dysplasia to high-riding dislocations. We report the management of DDH in children using the Dega osteotomy and their long-term follow-up.

METHODS: Fifty-eight hips from 48 children younger than 8 years treated using the Dega osteotomy between January 1988 and October 2000 were included in this multcenter study. Both prospective (41 hips) and retrospective (17 hips) cases were included, and follow-up was for a minimum of 13 years. Radiographs were made preoperatively, immediately postoperatively, after 6 weeks or at removal of the spica cast if any, at 6-month intervals and/or as indicated for 3 years postoperatively and then on annual basis until the last follow-up. A single-cut computed tomographic scan was performed for all prospective patients. Special attention was paid to the predictive measures of hip arthrosis and the survival of the hip after Dega osteotomy.

RESULTS: The final clinical outcome was favorable in 44 hips (75.9 %). Eleven hips needed a second surgery (acetabuloplasty and/or arthroplasty) during the follow-up period.

CONCLUSIONS: In our pediatric patient population the Dega osteotomy proved to be an adequate measure for the management of this complex condition. The worst complication was avascular necrosis, and all of the affected hips ended with failure (pain, another surgery, or both).

The reaction cross section (σ R) for a deformed target nucleus and spherical projectile is calculated using the optical-limit approximation of the Glauber-Sitenko theory. A method is presented to include both the density-dependent N N interaction and the higher order deformations of the target nucleus in the collision process. We studied both the orientation and the deformation dependence of σ R within the energy range 30-900 MeV/A We found that the orientation of the heavy target nucleus (A ≥ 120) can produce a difference in the calculated σ R up to 30%. The averaged σ R over all directions of the symmetry axis of the deformed nucleus differs by less than 1 % compared with σ R calculated for a spherical target with the same rms matter radius as the deformed nucleus. For certain orientation, it was found that σ R is highly dependent on the hexadecapole deformation. The orientation-averaged cross sections show almost no variation with either the sign or the value of the hexadecapole deformation. We compared the average cross section with the experimental data for several mass numbers; fair agreement is obtained. © 2003 MAIK "Nauka/Interperiodica".

PURPOSE: We identified an evidence-based definition of biochemical success following primary whole gland prostate cryoablation.

MATERIALS AND METHODS: The COLD Registry was queried for a risk stratified cohort of otherwise treatment naïve patients who underwent primary whole gland prostate cryoablation, of whom none had received any type of adjuvant therapy. Minimum followup in all study patients was 5 years. Variables included patient age, prostate specific antigen at diagnosis, Gleason score, D'Amico risk category and followup prostate specific antigen. Biochemical progression-free survival was studied based on Kaplan-Meier results using the Phoenix definition. HRs were calculated using proc PHReg.

RESULTS: Of 1,111 patients 891 achieved nadir prostate specific antigen less than 0.4 ng/ml, which correlated with a 5-year biochemical progression-free survival rate of 90.4% in those at low risk, 81.1% in those at intermediate risk and 73.6% in those at high risk. Nadir prostate specific antigen 0.4 ng/ml or greater was associated with 24-month biochemical failure of 29.2% in those at low risk, 46.4% in those at intermediate risk and 48.9% in those at high risk. Statistical analysis failed to reveal a superior prostate specific antigen end point compared to 0.4 ng/ml. HR findings supported the relevance of the end point of less than 0.4 ng/ml (p <0.0001).

CONCLUSIONS: To our knowledge this study represents the first evidence-based definition of biochemical success after primary whole gland prostate cryoablation. Nadir prostate specific antigen less than 0.4 ng/ml was the best objective indicator of biochemical success. Nadir prostate specific antigen 0.4 ng/ml or greater was associated with less favorable biochemical progression, precluding the use of a higher nadir prostate specific antigen end point (HR 5.649, 95% CI 4.33-7.38, p <0.0001).
