Racial and gender differences of cervical vertebral maturation staging between African Americans versus Caucasian patients of various age groups: A retrospective study.

BACKGROUND AND OBJECTIVE: The primary purpose of this study was to compare CVM staging between African American (AA) and Caucasian (CC) subjects, grouped based on gender. The secondary objectives were to conduct a CVM comparison of (1) male vs. female subjects, grouped based on their race, and (2) AA vs. CC subjects, categorized based on their age group. MATERIALS AND METHODS: All patients between 8-18 years of age (University of XXX), meeting the criteria, were included between the period of the year 2007 to 2020. Three blinded independent evaluators analysed the lateral cephalograms for a 6-stage CVM system (CS1 to CS6) as described by McNamara and Franchi. Samples were divided based on race, gender, and age to conduct the statistical analysis for racial and gender comparisons. RESULTS: Out of the initial 1,300 lateral cephalograms, 1,276 with the mean age: 12.7 years SD 2.5 years, and median CVM: 4 (IQR: 25% percentile- 2 and 75% percentile- 4) were included. Gender-specific racial age comparison showed no significant differences for male subjects for most of the CVM stages (P>0.05). Overall and race-specific gender comparison of age showed significant differences for almost all CVM stages (P<0.05). No significant difference of CVM was found on racial comparison for overall, females (P=0.6131) or males (P=0.0825) subjects. On age-specific racial comparison, AA girls (8-10 years) were skeletally more mature than CC girls (P=0.0143); over 14-year-old CC girls (P<0.0001) and over 16-year-old CC boys (P=0.0008), being skeletally more mature than AA boys of the same age. CONCLUSIONS: There was no significant difference between AA and CC subjects on gender-specific comparisons for most of the CVM stages. A significant difference of age was observed for most of the CVM stage between male and female subjects on race-specific comparisons. Female patients were ahead in skeletal maturity as compared to males for each CVM stage. The CVM for 8-12-year-old AA females was significantly higher than that of the CC females, whereas the CVM for>14-year-old CC females was significantly higher than AA females.

Autologous fat grafting to the reconstructed breast: the management of acquired contour deformities.

BACKGROUND: Autologous fat grafting has become a workhorse for soft-tissue augmentation throughout the body. In the reconstructed breast, autologous fat grafting is a useful tool for managing secondary contour deformities. The authors have categorized these deformities into three types: type 1 deformities are step-off deformities between the chest wall/reconstructed breast interface, type 2 deformities result from intrinsic deficiencies within a flap such as fat necrosis, and type 3 deformities are the result of extrinsic factors such as postoperative irradiation. METHODS: The authors conducted a detailed retrospective review of 110 patients who have received fat grafting to the reconstructed breast for the management of contour deformities. In addition, the authors reviewed the recent literature describing the use of autologous fat grafting to the breast. Particular attention has been placed on the concerns of oncologic surveillance in reconstructed breasts that have undergone fat grafting. RESULTS: The authors have had relative success in the treatment of patients who will require postoperative irradiation and even those who have rippling surrounding an implant. CONCLUSIONS: Autologous fat grafting represents an important tool for the management of secondary contour deformities of the reconstructed breast. Fat grafting is a simple, safe, and effective treatment option, with low morbidity.

Reconstruction of extensive partial or total sacrectomy defects with a transabdominal vertical rectus abdominis myocutaneous flap.

Following partial or total sacrectomy, extensive soft tissue defects are frequently created. These ablations typically involve an anterior and a posterior approach, creating a large communication between the abdominal cavity and the central gluteal region. Local flap options are usually not sufficient for definitive closure of these large defects. We have found that the most useful option for reconstruction in these cases is a vertical rectus abdominis myocutaneous (VRAM) flap, passed transabdominally through the peritoneal cavity into the sacral defect during the initial anterior-approach portion of the procedure and then inset following completion of the posterior-approach final resection. Advantages of the VRAM flap are that it can supply ample skin, as well as soft tissue bulk, is easy to perform, and does not require microvascular techniques. Utilizing a prospectively maintained database, all patients over the last 14 years who underwent reconstruction utilizing a transabdominal VRAM flap following extensive partial or total sacrectomy with intraabdominal communication were identified. A retrospective chart review was then performed. Our study population consisted of 12 patients with a mean age of 58.5 years. Following sacrectomy, all patients underwent reconstruction with a VRAM flap. Flap sizes averaged 9.1 x 27 cm. Early flap complications included 3 small areas of flap necrosis at the distal, superior portion of the flap, 2 of which required minimal operative intervention of debridement and reclosure. No late flap complications have occurred, and all 12 patients completely healed, with a mean follow-up time of 29.1 months. Following sacrectomy, extensive soft tissue defects are created in the sacral area and communicate with the abdominal cavity. In these situations, we have found the inferiorly-based pedicled VRAM, passed transabdominally, to be the most reliable and useful choice of flap reconstruction. It has a low incidence of complications, low morbidity, and is easy to perform with a high success rate.

Skin-sparing mastectomy and immediate reconstruction is an acceptable treatment option for patients with high-risk breast carcinoma.

BACKGROUND: Skin-sparing mastectomy (SSM) followed by immediate reconstruction is an effective treatment option for patients with early-stage breast carcinoma, but its use in patients with more advanced disease is controversial. METHODS: A retrospective review was performed that included 38 consecutive patients with high-risk breast carcinoma who underwent SSM and immediate reconstruction (between July 1996 and January 2002). Tumor characteristics, type of reconstruction, margin status, timing of adjuvant therapy, postoperative complications, and incidence of recurrence were evaluated. RESULTS: High-risk patients (Stage IIA [n=4 patients] Stage IIB [n=23 patients] Stage IIIA [n=8 patients] and Stage IIIB [n=3 patients]) underwent immediate reconstruction after SSM with the use of a transverse rectus abdominis myocutaneous flap (n=31 patients), a latissimus dorsi myocutaneous flap plus an implant (n=3 patients), or tissue expanders with subsequent implant placement (n=4 patients). The median follow-up was 52.9 months (range, 27.5-92.0 months), and the median time to recurrence has not yet been reached at the time of last follow-up. The median interval from surgery to the initiation of postoperative adjuvant therapy was 38 days (range, 25-238 days). Local recurrence was seen in 1 patient (2.6%), systemic recurrence in was seen in 10 patients (26.3%), and both local and distant metastases in were seen in 2 other patients (5.3%). CONCLUSIONS: SSM with immediate reconstruction appeared to be an oncologically safe treatment option for high-risk patients with advanced stages of breast carcinoma. In addition to the aesthetic and psychological benefits of performing SSM with immediate reconstruction, local recurrence rates and disease-free survival were favorable when combined with the use of radiation therapy and adjuvant chemotherapy, as indicated.
