RESUMEN

Background: High-grade isthmic spondylolisthesis poses a clinical challenge in the pediatric and adolescent population. Current surgical management using posterior-based approaches may lead to incomplete reduction and restoration of listhesis, disc height, and lordosis. Combined anterior and posterior approach addresses these issues but has been infrequently reported, mainly in the treatment of low-grade isthmic spondylolisthesis. Neither offers good disc space visualization and control of spinal alignment during reduction. Case Description: A healthy 17-year-old female presented with 9 months of progressively worsening lower back pain radiating down the left lower extremity and 3 inches of height loss. Diagnosis of grade IV L5-S1 spondylolisthesis was made using plain radiographs, CT, and MRI. Management with combined anterior and posterior fusion, involving the manual manipulation of segments using an anterior pedicle screw joystick, was pursued. Outcome: Satisfactory alignment, solid arthrodesis, no complications, and improved patient reported outcomes. Conclusions: Combined anterior and posterior fusion with anterior joystick manipulation allowed for full reduction of grade IV spondylolisthesis and restoration of disc/foraminal height and L5-S1 segmental lordosis without neurological complication. Although less commonly performed in children and adolescents, this surgical approach can assist in restoring optimal alignment in isthmic spondylolisthesis.

RESUMEN

Purpose: To compare subjective outcomes and complications of anterior cruciate ligament reconstruction (ACLR) using either bone-patellar tendon-bone (BPTB) or quadriceps tendon (QT) autograft. Methods: A retrospective analysis of prospectively collected data identified consecutive cohorts of patients undergoing ACLR with either BPTB or QT autograft. Patients with less than 12-month follow-up and those undergoing concomitant osteotomies, cartilage restoration, and/or other ligament reconstruction procedures were excluded. Pre- and postsurgical patient-reported outcomes including International Knee Documentation Committee, Knee Injury and Osteoarthritis Outcome Score, Patient-Reported Outcomes Measurement Information System (PROMIS), Single Assessment Numeric Evaluation, Tegner, and Marx were compared between groups. Complications requiring reoperation were recorded. Results: One hundred nineteen patients met inclusion criteria, including 39 QT autografts and 80 BPTB autografts. Demographic information was comparable between groups. Mean follow-up was comparable between groups (QT 22.4 ± 10.6 months vs BPTB 28.5 ± 18.5 months, P = .06). At minimum 12-month follow-up (range 12.0-100.8 months), patients in both groups demonstrated statistically significant improvements in International Knee Documentation Committee (QT 60.0%, P < .0001; BPTB 57.7%, P < .0001), all Knee Injury and Osteoarthritis Outcome Score domains, PROMIS Mobility T-Score (QT 27.2%, P = .0001; BPTB 23.2%, P < .0001), PROMIS Global Physical Health (QT 14.4%, P = .002; BPTB 13.4%, P = .001), PROMIS Physical Function (QT 29.6%, P < .0001; BPTB 37.1%, P < .0001), PROMIS Pain Interference (QT -16.5%, P < .0001; BPTB -20.8%, P < .0001), Single Assessment Numeric Evaluation, (QT 76.9%, P < .0001; BPTB 73.3%, P < .0001), Tegner (QT 92.9%, P = .0002; BPTB 101.4%, P < .0001), and Marx (QT -26.6%, P = .02; BPTB -32.0%, P = .0002) with no statistically significant differences between the 2 groups. Overall postoperative reoperation rate did not differ between groups (QT 12.8% vs BPTB 23.8%, P = .2). Revision ACL reconstruction rate did not differ between groups (QT 5.1% vs BPTB 7.5%, P = .6). Conclusions: Patients undergoing autograft ACLR with either BPTB or QT demonstrated significant subjective improvements in patient-reported outcomes from preoperative values and no statistically significant differences in outcomes between the groups. Complication and revision ACLR rates were similar between the 2 groups. Level of Evidence: III, retrospective cohort study.

RESUMEN

It is easy to capture and share clinical photographs and x-ray images using modern smartphones. This technology affords health-care providers the ability to rapidly collaborate and facilitate care for their patients. This improvement, however, has increased concerns regarding patient privacy and the safeguarding of protected health information. Health-care providers should understand the deidentification process for patient photographs because this process fundamentally changes the expectations and requirements for how providers are to handle this information. Properly deidentified patient photographs (and other data) are no longer considered identifiable protected health information and are not subject to the handling requirements mandated by the Health Insurance Portability and Accountability Act. This article addresses patient privacy concerns attendant to the acquisition, transmission, and sharing of clinical photographs among health-care providers. It provides guidelines for providers seeking to minimize the risk of noncompliance with privacy requirements as they adopt these new technologies into their practices.

RESUMEN

UNLABELLED: Oral squamous cell carcinoma (OSCC) is a cancer subtype that lacks validated prognostic and therapeutic biomarkers, and human papillomavirus status has not proven beneficial in predicting patient outcomes. A gene expression pathway analysis was conducted using OSCC patient specimens to identify molecular targets that may improve management of this disease. RNA was isolated from 19 OSCCs treated surgically at the University of Alabama at Birmingham (UAB; Birmingham, AL) and evaluated using the NanoString nCounter system. Results were confirmed using the oral cavity subdivision of the Head and Neck Squamous Cell Carcinoma Cancer (HNSCC) study generated by The Cancer Genome Atlas (TCGA) Research Network. Further characterization of the in vitro phenotype produced by Notch pathway activation in HNSCC cell lines included gene expression, proliferation, cell cycle, migration, invasion, and radiosensitivity. In both UAB and TCGA samples, Notch pathway upregulation was significantly correlated with patient mortality status and with expression of the proinvasive gene FGF1 In vitro Notch activation in HNSCC cells increased transcription of FGF1 and induced a marked increase in cell migration and invasion, which was fully abrogated by FGF1 knockdown. These results reveal that increased Notch pathway signaling plays a role in cancer progression and patient outcomes in OSCC. Accordingly, the Notch-FGF interaction should be further studied as a prognostic biomarker and potential therapeutic target for OSCC. IMPLICATIONS: Patients with squamous cell carcinoma of the oral cavity who succumb to their disease are more likely to have upregulated Notch signaling, which may mediate a more invasive phenotype through increased FGF1 transcription.

RESUMEN

OBJECTIVES: (1) Investigate overall survival (OS) and disease-free survival (DFS) for high-risk head and neck basal cell carcinoma (HNBCC) requiring large extirpation with free-flap reconstruction. (2) Determine impact of prognostic features-tumor size, subsite, number of high-risk features, perineural invasion, and bony invasion-on high-risk HNBCC survival. (3) Determine survival benefit of adjuvant radiation for high-risk HNBCC. STUDY DESIGN: Case series with chart review (2002-2013). SETTING: Academic tertiary care center. SUBJECTS AND METHODS: Consecutive head and neck patients (N = 431) required free-flap reconstruction following tumor extirpation, 38 for aggressive HNBCC. All cases were high risk. DFS and OS were examined using Kaplan-Meier analysis. Prognostic variables and adjuvant radiation were analyzed utilizing Student's t test for continuous variables and Fisher's exact testing for categorical dependent variables. Complications were reported. RESULTS: Mean tumor diameter was 5.17 cm (range, 1.2-15.0 cm). Mean follow-up was 19.9 months. Overall 2-year survival was 80%, falling to 66% at 5 years. Two-year disease-free survival was 72%. Six patients recurred (n = 5 local, 1 distant). Adjuvant radiotherapy improved DFS (P < .01) but not OS (P = .66). Tumors >2.5 cm did not affect OS (P = .61), regardless of subsite. Bone involvement (44.7% cases) did not affect DFS (P = .39) or OS (P = .18). CONCLUSIONS: Larger HNBCC warranting free tissue transfer do not confer worse outcomes, independent of subsite. Adjuvant radiotherapy does not improve OS but significantly affected DFS, allowing for 13.7 additional months of DFS. Bone involvement does not influence DFS or OS and should not preclude surgery, even in advanced cases requiring free-flap reconstruction.

RESUMEN

OBJECTIVES/HYPOTHESIS: To evaluate bone invasion, survival, and expression of bone morphogenetic protein-6 (BMP-6) in oral cavity cancer in the context of known biomarkers indicative of poor prognosis. STUDY DESIGN: Molecular expression study combined with retrospective chart review of corresponding patients at a tertiary care center. METHODS: Between 2000 and 2009, a total of 197 patients underwent resection for oral cavity squamous cell carcinoma. Of these, 30 pathologic specimens were chosen for further molecular analysis. These 30 patients were separated into three groups (10 per group) based on American Joint Committee on Cancer (AJCC) staging and staging based on size alone (TAJCC /SIZE ). The first group consisted of tumors staged as T2 /2 based on size less than 4 cm and that had no evidence of bone invasion. The T2 /4 group consisted of tumors that were upstaged from T2 based on bone invasion. The T4 /4 group consisted of tumors that were large with and without bone invasion. The expression of extracellular matrix metalloproteinase inducer (EMMPRIN), BMP-6, and epidermal growth factor receptor (EGFR) was examined using immunohistochemistry techniques. Patient demographics, tumor characteristics, survival, and recurrence were compared. RESULTS: Average follow-up was 21 months. Expression of BMP-6 was significantly higher in the T2 /4 cohort (tumor less than 4 cm with bony invasion) than the larger tumors without bone invasion (T4 /4 cohort, P = .05). In addition, increased BMP-6 expression correlated with aggressive behavior in the smaller tumors. Furthermore, increased EGFR expression positively correlated with increased levels of BMP-6. CONCLUSIONS: Increased expression of BMP-6 in oral cavity cancer may affect bone invasion.
