Single fraction spine stereotactic ablative body radiotherapy with volumetric modulated arc therapy.

This study investigated a single institution's experience with volumetric modulated arc therapy (VMAT) directed stereotactic ablative body radiotherapy (SABR) for vertebral metastases. From 2010 to 2014, 95 lesions of spinal metastases in 73 patients were treated with SABR using VMAT. Clinical local control, pain level, and use of steroid medication were employed to evaluate treatment responses. The majority (79%) of patients were treated with a radiation dose of 20 Gy in a single fraction. However, when normal tissue constraints could not be achieved, the dose was reduced to 18 Gy (11%) or 16 Gy (8%) in 1 fraction. At the median follow up of 12.7 months (mean 18.0, range 1-56 months), clinical local control was 97% (92 out of 95). There was a mean 81% (median 100%, range 28-100%) decrease in subjective pain score. Seventy-seven percent of patients had a decrease in narcotic pain medication use. Pain was completely resolved at the treatment site for 69% (66/95) of patients. Prior to the SABR treatment, 33% (31/95) of patients had epidural extension of tumor. Among patients with epidural involvement, 45% (14/31) exhibited neurologic impairment prior to treatment. Twenty-three percent (7/31) experienced spinal cord compression. Prior to treatment, 34 patients experienced some form of neurologic impairment. Of these patients, 24% (8/34) experienced improved motor functioning; the remaining 76% (26/34) of patients' neurological dysfunction were stable. Our results indicate the SABR regimen using VMAT technique is clinically effective in achieving clinical local control and palliation. This is the first publication reporting clinical outcomes of VMAT directed SABR.

The Value of Signaling an Orthopaedic Surgery Program: A Survey to Orthopaedic Surgery Programs.

INTRODUCTION: A new system was implemented by the Association of American Medical Colleges called the preference signaling program for the 2022 to 2023 orthopaedic surgery residency match. Applicants were able to signal 30 orthopaedic surgery programs to indicate high interest in a specific program. The purpose of this study was to address how important signaling was to an orthopaedic surgery program this 2022 to 2023 application cycle. METHODS: A five-question survey was sent to orthopaedic surgery residency programs participating in the Electronic Residency Application Service this application cycle. Contact information was gathered through the Accreditation Council for Graduate Medical Education residency website and program websites. RESULTS: Responses were obtained from 69 of the 151 programs (46%) contacted. The average number of applicants per program was 727 (range, 372 to 1031, SD 155). Thirty-four of 61 respondents (56%) stated that 100% of their interviewees signaled their program. Fifty-five of 61 respondents (90%) indicated that their interviewee pool consisted of 75% or more applicants who signaled. Applicants who signaled had a 24.4% (range, 12.77 to 47.41, SD 8.04) chance of receiving an interview. Applicants who did not signal had just a 0.92% (range, 0 to 13.10, SD 2.08) chance of receiving an interview. Fifty-four of the 63 applicants (86%) answered that signaling played an important role in considering an applicant for an interview. CONCLUSION: Over half of the responding programs only interviewed applicants who signaled their program, and over 90% of programs' interview lists consisted of at least 75% of signaling applicants. Eighty-six percent of programs indicated that signaling played an important role in considering an applicant for an interview. Applicants who signaled were 26.5 times more likely to receive an interview than those who did not (P < 0.0001). With this information, applicants can narrow down their list of programs to apply to, knowing that their signal to a program will give them a better chance at receiving an interview.

Tumoral calcinosis of the knee treated with open, physeal sparing iliotibial band ACL reconstruction.

Tumoral calcinosis is a hereditary disease of calcium and phosphate metabolism causing peri-articular tumors of calcium deposits. We present a case of tumoral calcinosis in a 13-year-old male with a history of a 12q13.11 genetic deletion. Surgical resection of the tumor necessitated resection of the ACL in its entirety with curettage and adjuvant therapy to the lateral femoral notch, which resulted in ligamentous instability and bony structural incompetency at the femoral insertion. Given the patient's radiographically-apparent skeletal immaturity, and lack of reliable bony architecture to accommodate a femoral ACL tunnel, ACL reconstruction was performed using a physeal-sparing technique. This is a case of tumoral calcinosis treated with, to our knowledge, the first ACL reconstruction using this modified open technique.

Intraoperative navigation and preoperative templating software are associated with increased glenoid baseplate screw length and use of augmented baseplates in reverse total shoulder arthroplasty.

BACKGROUND: Preoperative templating software and intraoperative navigation have the potential to impact baseplate augmentation utilization and increase screw length for baseplate fixation in reverse total shoulder arthroplasty (rTSA). We aimed to assess their impact on the (1) baseplate screw length, (2) number of screws used, and (3) frequency of augmented baseplate use in navigated rTSA. METHODS: We compared 51 patients who underwent navigated rTSA with 63 controls who underwent conventional rTSA at a single institution. Primary outcomes included the screw length, composite screw length, number of screws used, percentage of patients in whom 2 screws in total were used, and use of augmented baseplates. RESULTS: Navigation resulted in the use of significantly longer individual screws (36.7 mm vs. 30 mm, P < .0001), greater composite screw length (84 mm vs. 76 mm, P = .048), and fewer screws (2.5 ± 0.7 vs. 2.8 ± 1, P = .047), as well as an increased frequency of using 2 screws in total (35 of 51 patients [68.6%] vs. 32 of 63 controls [50.8%], P = .047). Preoperative templating resulted in more frequent augmented baseplate utilization (76.5% vs. 19.1%, P < .0001). CONCLUSION: The difference in the screw length, number of screws used, and augmented baseplate use demonstrates the evolving role that computer navigation and preoperative templating play in surgical planning and the intraoperative technique for rTSA.

Adolescent vertebral osteomyelitis mimicking a neoplasm.

A 14-year-old previously healthy girl presented with atraumatic onset of low back and flank pain and mildly elevated inflammatory markers. Magnetic resonance imaging disclosed an L5 superior endplate fracture, and cultures grew methicillin-susceptible Staphylococcus aureus. We discuss the variable presentations and appropriate treatments of adolescent vertebral osteomyelitis.

Primary bone sarcoma with BCOR internal tandem duplication.

BCOR internal tandem duplications (ITDs) and rearrangements are implicated in the oncogenesis of a subset of undifferentiated sarcomas. To date, BCOR ITD sarcomas have been exclusively found in non-appendicular infantile soft tissues, whereas BCOR-rearranged sarcomas occur in both bones and soft tissues affecting a wider patient age range. Little is known about patient outcome in BCOR ITD sarcomas. We present a BCOR-expressing, primary bone, undifferentiated sarcoma case involving an adolescent male's left tibia that, unexpectedly, harbored a BCOR ITD instead of a BCOR rearrangement. Furthermore, the patient achieved a partial histologic response after receiving a Ewing sarcoma chemotherapy regimen. Our case expands the clinical spectrum of BCOR ITD sarcomas and suggests that childhood and adult BCOR-expressing sarcomas with an undifferentiated histology should be considered for both BCOR rearrangement and ITD screening. Accurate BCOR mutation identification in undifferentiated sarcomas is essential to define their clinical spectrum and to develop effective management strategies.

Multiple parent-adult child relations and well-being in middle and later life.

OBJECTIVES: Despite the centrality of parent-adult child relations, prior research has found only weak associations with parent well-being. There is a need to give more explicit attention to the relations of parents with multiple children and to the potentially mixed or "ambivalent" nature of those relations. These patterns may differ for mothers and fathers. METHODS: Wave 1 of the National Survey of Families and Households provided detailed information on relations between parents and each of their adult children. The sample included 2,270 persons aged 50+ who had at least one child aged 19+. RESULTS: Measures across multiple adult children uncovered more mixed patterns of "collective ambivalence" that included lesser quality and/or contact with at least some children. The presence of less positive relations with any children was consistently, albeit modestly, related to lower parent well-being. Mothers reported higher "maximum" quality and interaction across children, but mothers and father did not differ in "minimum" reports. Associations between parent-child relations and well-being were similar for mothers and fathers. DISCUSSION: Analyses that incorporate the relations of parents with their multiple adult children, viewed as part of a family network, yield a more comprehensive and nuanced view of those relations and their implications for well-being.

Fibrous Dysplasia in the Calcaneus.

Fibrous dysplasia in the calcaneus is extremely rare; the most common locations of monostotic fibrous dysplasia of extremity bones being the proximal femoral shaft, tibia, humerus, and radius. An extensive literature search has revealed only 3 case reports that have been published concerning this topic, the most recent published in 2003. This is a case report of fibrous dysplasia in the calcaneus of a young male, including a discussion of the classical presentation of fibrous dysplasia and how this case differed. LEVELS OF EVIDENCE: Therapeutic, Level IV: Case study.

Close To You? How Parent-Adult Child Contact Is Influenced by Family Patterns.

OBJECTIVES: Intergenerational contacts occur in the context of other family relationships. We examine how in-person contacts among parents and all adult children affect each other, focusing on proximity and other predictors to assess whether and how visiting is correlated across adult children. METHODS: We use a modeling approach derived from an adaptation of multilevel models to provide a convenient mechanism by which to write child-specific equations, each with its own set of predictors, and wherein one child's attribute values can be attached to other children's records. RESULTS: We find that parent-adult child visiting is positively correlated across siblings, but the frequency of visiting within families is not directly reciprocated. Rather, visiting responds to common family factors. Visiting declines with distance, but there are strong discontinuities in the effect. Distance between parents and a focal child is positively associated with visiting with other children. DISCUSSION: The empirical patterns we report can be framed within enhancement and compensation models. Positive correlations and cross-sibling interactions that juxtapose levels of visiting against not seeing a child in last 12 months are consistent with the enhancement model. The cross-sibling interaction for distance, whereby one child's farther distance leads to more visits reported with others, provides evidence of a countervailing, though, weaker, pattern of compensation for proximity.

Marital implications of parent-adult child coresidence: a longitudinal view.

OBJECTIVES: This study assesses implications of changes in coresidence with adult children for parents' marital relations, hypothesizing that transitions into coresidence lower marital quality and transitions out of coresidence increase marital quality. METHODS: Panel data from Waves 1 and 2 of the National Survey of Families and Households are used to analyze whether change in three measures of marital quality-time together, happiness, and disagreements-is related to adult child coresidence. RESULTS: When adult children move out, parent couples increase their time together; there is a tendency for reduced time together when the nest "refills." However, there are no effects of moves in or out on the marital happiness of parents or the number of marital disagreements they have. There is also no effect on time together or on marital quality when one adult child moves out but another moves in during the same period. The presence of younger children has more consistent associations with marital quality. DISCUSSION: Coresidence with adult children does not appear to be an experience that disrupts the quality of marital relations. It may be that qualitative dimensions of coresidence experiences with adult children matter more than coresidence per se.

Change in perceived age in middle and later life.

Analyses examine change in the age people "feel" (felt age) and "would like to be" (ideal age) (relative to current age) in middle and later life. Data are from 1,815 respondents in two waves (1995-96, 2004-06) of the Midlife in the United States Survey (MIDUS) who were age 40+ at Wave 1. In aggregate, people feel about the same amount younger but become increasingly distant from preferred age. Favorable health trends between waves and better expected future health are related to younger felt age, cross-sectionally and longitudinally. Health is not related to ideal age, but education and (for respondents younger than 60) better financial expectations are associated with less youthful ideal age. Patterns for felt age appear to reflect images of later life as a time of physical decline, whereas ideal age appears to be shaped more by socioeconomic considerations.

Atypical intradermal smooth muscle neoplasms (formerly cutaneous leiomyosarcomas): case series, immunohistochemical profile and review of the literature.

Atypical intradermal smooth muscle neoplasms (AISMN, formerly known as cutaneous leiomyosarcomas) are uncommon neoplasms, which seem to be remarkable for their excellent prognosis in contrast to their deeper counterparts. The rarity of AISMN has posed a challenge for characterizing the morphologic spectrum, immunohistochemical staining pattern, and behavior. In this study we evaluated the histologic and immunohistochemical features of 20 cases of AISMN. Clinical follow-up was available on 19 out of 20 patients and ranged from 1 to 124 months with an average of 35 months and a median of 20 months with a male predominance (male to female ratio was 2.3:1). Our data show a wide variation in differentiation and atypical features. Among these, the presence of mitotic figures is diagnostically valuable in rendering the final diagnosis. A broad panel of immunohistochemical stains revealed that smooth muscle actin and muscle specific actin, when used in combination, identified smooth muscle differentiation in 100% of the cases. With some caveats, CD34, S100, and CK 5/6 were helpful in ruling out other important cutaneous spindle cell neoplasms. Significantly, loss of phosphatase and tensin homolog (PTEN) staining was seen in the majority of our cases (80%), supporting a role for PTEN loss in the etiology of these lesions. Logistic regression analysis revealed that positive margin status was helpful for predicting recurrence (100% sensitivity and 94% specificity). We conclude that AISMN can have significant morphologic variation and overlap with other spindle cell neoplasms of the skin and that a limited panel of key immunohistochemical stains should be used to distinguish this lesion. The different surgical measures such as wide excision versus Mohs procedure showed a similar clinical outcome. Although the significance of frequent PTEN loss supports a molecular mechanism of tumor genesis, the diagnostic utility of the stain remains to be determined.

Intraoperative navigation for minimally invasive resection of periarticular and pelvic tumors.

The surgical approach to benign, metastatic, and some low-grade malignant tumors is often difficult due to their typically precarious locations. This article presents a series of cases where intraoperative stealth navigation was used to treat periarticular tumors. The use of paired point imaging with image fusion has made approaching tumors through an accurate and minimally invasive technique a viable option for the treatment of a subset of musculoskeletal tumors.

How old am I? Perceived age in middle and later life.

Literatures on perceived age and developmental issues in middle and later life are joined in analyzing perceived age and its implications for well-being. Respondents aged 40-74 (N = 2,696) are drawn from the national MIDUS survey, containing developmental variables such as personal growth and insight into past. People generally "feel" (felt age) and would "like" (ideal age) to be younger, but these exhibit different predictors and outcomes. Younger felt age is associated with positive developmental assessments and enhanced well-being, whereas younger ideal age is associated with less positive assessments and lower well-being. The association between felt age and well-being is moderated by developmental assessments. The contrasting patterns exhibited by felt age and ideal age reflect the complexities of age perceptions. It is suggested that felt age entails perceptions of current circumstances as they relate to expectations about aging, whereas ideal age reflects a comparative overview of the life cycle.
