RESUMO
BACKGROUND: Magnetic resonance imaging (MRI) is the only imaging modality capable of directly visualizing the levator veli palatini (LVP) muscles: the primary muscles responsible for velopharyngeal closure during speech. MRI has been used to describe normal anatomy and physiology of the velopharynx in research studies, but there is limited experience with use of MRI in the clinical evaluation of patients with velopharyngeal insufficiency (VPI). METHODS: MRI was used to evaluate the velopharyngeal mechanism in patients presenting for VPI management. The MRI followed a fully awake, nonsedated protocol with phonation sequences. Quantitative and qualitative measures of the velopharynx were obtained and compared with age- and sex-matched individuals with normal speech resonance. RESULTS: MRI was completed successfully in 113 of 118 patients (96%). Compared with controls, patients with VPI after cleft palate repair had a shorter velum (P < 0.001), higher incidence of LVP discontinuity (P < 0.001), and shorter effective velar length (P < 0.001). Among patients with persistent VPI after pharyngeal flap placement, findings included a pharyngeal flap base located inferior to the palatal plane [11 of 15 (73%)], shorter velum (P < 0.001), and higher incidence of LVP discontinuity (P = 0.014). Patients presenting with noncleft VPI had a shorter (P = 0.004) and thinner velum (P < 0.001) and higher incidence of LVP discontinuity (P = 0.014). CONCLUSIONS: MRI provides direct evidence of LVP muscle anomalies and quantitative evaluation of both velar length and velopharyngeal gap. This information is unavailable with traditional VPI imaging tools, suggesting that MRI may be a useful tool for selecting surgical procedures to address patient-specific anatomic differences.

OBJECTIVE: To investigate whether flexible nasopharyngoscopy, when performed in addition to magnetic resonance imaging (MRI), influences the type of surgery selected or success of surgery in patients with velopharyngeal insufficiency (VPI). DESIGN: Cohort study. SETTING: A metropolitan children's hospital. PATIENTS: Patients with non-syndromic, repaired cleft palate presenting for management of VPI. INTERVENTIONS: MRI and nasopharyngoscopy or MRI alone for preoperative imaging of the velopharyngeal mechanism. MAIN OUTCOME MEASURES: (1) Surgical selection and (2) resolution of hypernasality. All speech, MRI, and nasopharyngoscopy measurements were performed by raters blinded to patients' medical and surgical history. RESULTS: Of the 25 patients referred for nasopharyngoscopy, 76% completed the exam. Of the 41 patients referred for MRI, the scan was successfully completed by 98% of patients. Completion of nasopharyngoscopy was significantly (p=0.01) lower than MRI. Surgical selection did not significantly differ (p=0.73) between the group receiving MRI and nasopharyngoscopy and the group receiving MRI alone, nor was there a significant difference between these groups in the proportion of patients achieving resolution of hypernasality postoperatively (p=0.63). Percent total velopharyngeal closure assessments on nasopharyngoscopy and MRI were strongly correlated (r=0.73). CONCLUSIONS: In patients receiving MRI as part of their preoperative VPI evaluation, the addition of nasopharyngoscopy did not result in a difference in surgical selection or resolution of hypernasality. Routine inclusion of nasopharyngoscopy may not be necessary for the evaluation of velopharyngeal anatomy when MRI is available.
RESUMO
Background: Secondary Furlow (Furlow) and buccal myomucosal flaps (BMMF) treat velopharyngeal insufficiency by lengthening the palate and retropositioning the levator veli palatini muscles. The criteria for choosing one operation over the other remain unclear. Methods: A single-center retrospective cohort study was conducted. Thirty-two patients with nonsyndromic, repaired cleft palate were included. All patients underwent a Furlow or BMMF. Outcome measures included (1) resolution of hypernasality 12 months postoperatively, (2) degree of improvement of hypernasality severity; and (3) change in velar length, as measured on magnetic resonance imaging scans obtained preoperatively and 12 months postoperatively. All measures were performed by raters blinded to participants' medical and surgical history. Results: Hypernasality was corrected to normal in 80% of the Furlow group and in 56% of the BMMF group. Patients receiving BMMF had more severe hypernasality during preoperative speech evaluation. Both groups had a median decrease of two scalar rating points for severity of hypernasality (P = 0.58). On postoperative magnetic resonance imaging, patients who underwent Furlow had a median increased velar length of 6.9 mm. Patients who received BMMF had a median increased velar length of 7.5 mm. There was no statistically significant difference between groups regarding increase in velar length (P = 0.95). Conclusions: Furlow and BMMF procedures increase velar length with favorable speech outcomes. The same degree of improvement for hypernasality was observed across groups, likely explained by the similar increase in velar length achieved. Anatomic changes in palate length and levator veli palatini retropositioning persist 1 year after surgery.
RESUMO
BACKGROUND: Motor vehicle collision (MVC) remains a leading cause of injury and death among children, but the proper use of child safety seats and restraints has lowered the risks associated with motor vehicle travel. Blunt cerebrovascular injury (BCVI) is rare but significant among children involved in MVC. This study reviewed the incidence of BCVI after MVC causing blunt injury to the head, face, or neck, comparing those that were properly restrained with those that were not. METHODS: A prospective, multi-institutional observational study of children younger than 15 years who sustained blunt trauma to the head, face, or neck (Abbreviated Injury Scale score >0) and presented at one of six level I pediatric trauma centers from 2017 to 2020 was conducted. Diagnosis of BCVI was made either by imaging or neurological symptoms at 2-week follow-up. Restraint status among those involved in MVC was compared for each age group. RESULTS: A total of 2,284 patients were enrolled at the 6 trauma centers. Of these, 521 (22.8%) were involved in an MVC. In this cohort, after excluding patients with missing data, 10 of 371 (2.7%) were diagnosed with a BCVI. For children younger than 12 years, none who were properly restrained suffered a BCVI (0 of 75 children), while 7 of 221 (3.2%) improperly restrained children suffered a BCVI. For children between 12 and 15 years of age, the incidence of BCVI was 2 of 36 (5.5%) for children in seat belts compared with 1 of 36 (2.8%) for unrestrained children. CONCLUSION: In this large multicenter prospectively screened pediatric cohort, the incidence of BCVI among properly restrained children under 12 years after MVC was infrequent, while the incidence was 3.2% among those without proper restraint. This effect was not seen among children older than 12 years. Restraint status in young children may be an important factor in BCVI screening. LEVEL OF EVIDENCE: Prognostic and Epidemiological; Level IV.

BACKGROUND: Blunt cerebrovascular injury (BCVI) is rare but significant among children. There are three sets of BCVI screening criteria validated for adults (Denver, Memphis, and Eastern Association for the Surgery of Trauma criteria) and two that have been validated for use in pediatrics (Utah score and McGovern score), all of which were developed using retrospective, single-center data sets. The purpose of this study was to determine the diagnostic accuracy of each set of screening criteria in children using a prospective, multicenter pediatric data set. METHODS: A prospective, multi-institutional observational study of children younger than 15 years who sustained blunt trauma to the head, face, or neck and presented at one of six level I pediatric trauma centers from 2017 to 2020 was conducted. All patients were screened for BCVI using the Memphis criteria, but criteria for all five were collected for analysis. Patients underwent computed tomography angiography of the head or neck if the Memphis criteria were met at presentation or neurological abnormalities were detected at 2-week follow-up. RESULTS: A total of 2,284 patients at the 6 trauma centers met the inclusion criteria. After excluding cases with incomplete data, 1,461 cases had computed tomography angiography and/or 2-week clinical follow-up and were analyzed, including 24 cases (1.6%) with BCVI. Sensitivity, specificity, positive predictive value, and negative predictive value for each set of criteria were respectively 75.0, 87.5, 9.1, and 99.5 for Denver; 91.7, 71.1, 5.0, and 99.8 for Memphis; 79.2, 82.7, 7.1, and 99.6 for Eastern Association for the Surgery of Trauma; 45.8, 95.8, 15.5, and 99.1 for Utah; and 75.0, 89.5, 10.7, and 99.5 for McGovern. CONCLUSION: In this large multicenter pediatric cohort, the Memphis criteria demonstrated the highest sensitivity at 91.7% and would have missed the fewest BCVI, while the Utah score had the highest specificity at 95.8% but would have missed more than half of the injuries. Development of a tool, which narrows the Memphis criteria while maintaining its sensitivity, is needed for application in pediatric patients. LEVEL OF EVIDENCE: Diagnostic Test/Criteria; Level II.

OBJECTIVE: To present the design and methodology for an actively enrolling comparative effectiveness study of revision palatoplasty versus pharyngoplasty for the treatment of velopharyngeal insufficiency (VPI). DESIGN: Prospective observational multicenter study. SETTING: Twelve hospitals across the United States and Canada. PARTICIPANTS: Individuals who are 3-23 years of age with a history of repaired cleft palate and a diagnosis of VPI, with a total enrollment target of 528 participants. INTERVENTIONS: Revision palatoplasty and pharyngoplasty (either pharyngeal flap or sphincter pharyngoplasty), as selected for each participant by their treatment team. MAIN OUTCOME MEASURE(S): The primary outcome is resolution of hypernasality, defined as the absence of consistent hypernasality as determined by blinded perceptual assessment of a standard speech sample recorded twelve months after surgery. The secondary outcome is incidence of new onset obstructive sleep apnea. Statistical analyses will use propensity score matching to control for demographics, medical history, preoperative severity of hypernasality, and preoperative imaging findings. RESULTS: Study recruitment began February 2021. As of September 2022, 148 participants are enrolled, and 78 have undergone VPI surgery. Enrollment is projected to continue into 2025. Collection of postoperative evaluations should be completed by the end of 2026, with dissemination of results soon thereafter. CONCLUSIONS: Patients with VPI following cleft palate repair are being actively enrolled at sites across the US and Canada into a prospective observational study evaluating surgical outcomes. This study will be the largest and most comprehensive study of VPI surgery outcomes to date.
RESUMO
Purpose: This study aims to describe the incidence of postoperative urinary retention among pediatric patients undergoing orthopedic surgery and identify risk factors. Methods: The Pediatric Health Information System was used to identify children aged 1−18 years who underwent orthopedic surgery. Collected from each patient's record were demographic information, principal procedure during hospitalization, the presence of neurologic/neuromuscular conditions and other complex chronic medical conditions, the total postoperative length of stay, and the presence of postoperative urinary retention. Results: The overall incidence of postoperative urinary retention was 0.38%. Children with complex chronic neuromuscular conditions (OR 11.54 (95% CI 9.60−13.88), p = < 0.001) and complex chronic non-neuromuscular medical conditions (OR 5.07 (95% CI 4.11−6.25), p ≤ 0.001) had a substantially increased incidence of urinary retention. Surgeries on the spine (OR 3.98 (95% CI 3.28−4.82, p ≤ 0.001) and femur/hip (OR 3.63 (95% CI 3.03−4.36), p ≤ 0.001) were also associated with an increased incidence. Conclusions: Children with complex chronic neuromuscular conditions have a substantially increased risk of experiencing postoperative urinary retention. Complex chronic non-neuromuscular medical conditions and surgeries to the spine, hip, and femur also carry a notably increased risk.
RESUMO
Empathy is the cornerstone of the patient-physician relationship and is consistently ranked by patients as one of the most important factors in the quality of their care. In this paper we examine the degree to which perceived physician empathy is associated with the characteristics of the caregiver (parent or legal guardian) and physician in pediatric orthopedic surgery. This was a cross-sectional survey study of 200 English-speaking caregivers of pediatric patients at a large children's hospital. The Consultation and Relational Empathy (CARE) Measure was used to measure perceived physician empathy. Only if the caregiver felt carefully listened to by the physician (p-value < 0.001), and if the physician showed respect for what the caregiver had to say (p-value = 0.007) were statistically significant and positively associated with perceived physician empathy. The most significant determinant of perceived physician empathy is whether the caregiver felt listened to during the encounter. Other factors such as caregiver demographics, health literacy, self-rated mental health, wait time, and time spent with the physician do not significantly affect perceived physician empathy.
RESUMO
This study investigates determinants of pediatric orthopedic surgery patients' parent or guardian (caregiver) satisfaction with the physician in an outpatient office setting. This was a cross-sectional survey study of 200 English-speaking caregivers of pediatric patients that checked into the pediatric orthopedic clinic at the authors' institution from 1 March 2017 to 1 November 2018. Questionnaires given in clinic include the Newest Vital Sign and The Literacy in Musculoskeletal Problems survey to measure general and musculoskeletal health literacy, respectively, demographic information, expected/estimated wait time, Consultation and Relational Empathy Measure, and Consumer Assessment of Healthcare Providers and Systems Clinician and Group. After multivariate regression, only perceived physician empathy as measured by the Consultation and Relational Empathy Measure score was significantly correlated with caregiver satisfaction (P < 0.0001), accounting for 56% of the variability of caregiver satisfaction scores. The odds of a satisfaction score of at least 9 out of 10 were 21% higher for every unit increase of the Consultation and Relational Empathy Measure score [odds ratio = 1.21 (P < 0.0001)]. After logistic regression, the caregiver's gender was also correlated with patient satisfaction and the odds of a patient satisfaction score ≥9 for males was less than 1/4th that of females [odds ratio = 0.16 (P = 0.040)]. The most important determinant of caregiver satisfaction with the physician in an outpatient pediatric orthopedic setting is perceived physician empathy. This accounts for the majority of the caregiver's satisfaction. This is the first study to determine this relationship in pediatric orthopedic surgery.

BACKGROUND: Palate re-repair has been proposed as an effective treatment for velopharyngeal insufficiency (VPI) with a low risk of obstructive sleep apnea (OSA). The authors conducted a systematic review and meta-analysis to determine the proportion of patients achieving normal speech resonance following palate re-repair for VPI, the proportion developing OSA, and the criteria for patient selection that are associated with increased effectiveness. METHODS: PubMed, Embase, and Scopus were searched from inception through April 2018 for English language articles evaluating palate re-repair for the treatment of VPI in patients with a repaired cleft palate. Inclusion criteria included reporting of hypernasality, nasal air emission, nasometry, additional VPI surgery, and/or OSA outcomes. Meta-analysis was conducted using random effects models. Risk of bias was assessed regarding criteria for patient selection, blinding of outcome assessors, and validity of speech assessment scale. RESULTS: Eighteen studies met inclusion criteria. The incidence of achieving no consistent hypernasality follow palate re-repair was 61% (95% confidence interval [CI]: 44%-75%). The incidence of additional surgery for persistent VPI symptoms was 21% (95% CI: 12%-33%). The incidence of OSA was 28% (95% CI: 13%-49%). Criteria for selecting patients to undergo re-repair varied, with anterior/sagittal position of palatal muscles (33%) and small velopharyngeal gap (22%) being the most common. No specific patient selection criteria led to superior speech outcomes (P = .6572). CONCLUSIONS: Palate re-repair achieves normal speech resonance in many but not all patients with VPI. Further research is needed to identify the specific examination and imaging findings that predict successful correction of VPI with re-repair.

OBJECTIVES: Electroencephalography is used in neurocritical care for detection of seizures and assessment of cortical function. Due to limited resolution from scalp electroencephalography, important abnormalities may not be readily detectable. We aimed to identify whether intracranial electroencephalography allows for improved methods of monitoring cortical function in children with severe traumatic brain injury. DESIGN: This is a retrospective cohort study from a prospectively collected clinical database. We investigated the occurrence rate of epileptiform abnormalities detected on intracranial electroencephalography when compared with scalp electroencephalography. We also investigated the strength of association of quantitative electroencephalographic parameters and cerebral perfusion pressure between both intracranial and scalp electroencephalography. SETTING: This is a single-institution study performed in the Phoenix Children's Hospital PICU. PATIENTS: Eleven children with severe traumatic brain injury requiring invasive neuromonitoring underwent implantation of a six-contact intracranial electrode as well as continuous surface electroencephalography. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Visual detection of epileptiform abnormalities was performed by pediatric epileptologists. Association of intracranial and scalp electroencephalography total power, alpha percentage, and alpha-delta power ratio to cerebral perfusion pressure was performed using univariate dynamic structural equations modeling. Demographic data were assessed by retrospective analysis. Intracranial and scalp electroencephalography was performed in 11 children. Three of 11 children had observed epileptiform abnormalities on intracranial electroencephalography. Two patients had epileptiform abnormalities identified exclusively on intracranial electroencephalography, and one patient had seizures initiating on intracranial electroencephalography before arising on scalp electroencephalography. Identification of epileptiform abnormalities was associated with subsequent identification of stroke or malignant cerebral edema. We observed statistically significant positive associations between intracranial alpha-delta power ratio to cerebral perfusion pressure in nine of 11 patients with increased strength of association on intracranial compared with scalp recordings. CONCLUSIONS: These findings suggest that intracranial electroencephalography may be useful for detection of secondary insult development in children with traumatic brain injury.

The aim of this study is to compare clinical outcomes of patients who underwent allogeneic stem cell transplantation (HCT) for myelofibrosis with reduced intensity conditioning (RIC) using either Busulfan Fludarabine (BuFlu), Fludarabine Bis-chlorethyl-nitroso-urea/ carmustine Melphalan (FBM) or Fludarabine Melphalan (FluMel) regimens. Sixty-one patients were identified who underwent HCT with one of these RIC regimens. Overall survival (OS) was not different in the 3 groups. However, 100% donor chimerism was seen in more frequently at day +30 and day +100 in patients who received FBM or FluMel than BuFlu, in both CD3 and CD33 fractions. For instance, 100% donor chimerism in CD33 fraction was present in 100% patients in FBM cohort, 90% in FluMel cohort while 44% in BuFlu cohort at day +100. Acute graft-versus host disease, grade 2-4 and grade 3-4, was not statistically different in the 3 groups (BuFlu 47 and 35%, FBM 68 and 27%, FluMel 68 and 46%; p = 0.31 and 0.45). Relapses and non-relapse mortality was also not statistically significantly different. Our study shows similar OS with these 3 RIC regimens in myelofibrosis; although donor chimerism at day +30 and day +100 was better in patients who received FBM and FluMel.

BACKGROUND: In recently updated breast cancer screening guidelines, the American Cancer Society (ACS) and United States Preventive Services Task Force (USPSTF) recommended increasing mammography screening intervals for various age groups. In addition, ACS does not recommend clinical breast examination (CBE) for routine screening among average-risk women. Our study explores women's attitudes regarding screening mammography and CBE and evaluates the impact of the updated USPSTF and ACS guidelines on these attitudes. MATERIALS AND METHODS: Six hundred fourteen patients presenting to Mayo Clinic, Arizona and Minnesota, in July 2016 completed a self-administered survey, which included a summary of the updated guidelines. RESULTS: A majority of the 555 women who fit the inclusion criteria reported that CBE and mammogram are useful in detecting breast cancer and should be performed annually, and 51% of participants were unaware of the updated guidelines. Before reviewing the guidelines, 77% believed yearly CBE and 76% believed yearly mammogram was needed for routine screening. After reviewing the guidelines, the percentage of women who planned to continue with yearly CBE and mammogram decreased significantly to 61% and 64%, respectively (p < 0.001 and p < 0.001). Nearly half the participants (48%) believed the most influential reason for the guideline change was to decrease healthcare spending. CONCLUSION: Breast cancer screening is well received among patients, and a majority of surveyed women were unaware of recent guideline changes. After reviewing the guidelines, there was a significant downward shift in intended screening frequency, although the majority still planned to undergo annual screening. Informing women about updated evidence-based guidelines may influence their knowledge, preferences, and opinions.

INTRODUCTION: Patients with malignancy represent a particular challenge for the emergency department (ED) given their higher acuity, longer ED length of stay, and higher admission rate. It is unknown if patients with malignancies and hyperlactatemia are at increased risk of mortality. If serum lactic acid could improve detection of at-risk patients with cancer, it would be useful in risk stratification. There is also little evidence that "alarm" values of serum lactate (such as >/=4 mmol/L) are appropriate for the population of patients with cancer. METHODS: This was a continuous retrospective cohort study of approximately two years (2012-2014) at a single, tertiary hospital ED; 5,440 patients had serum lactic acid measurements performed in the ED. Of the 5,440 patients in whom lactate was drawn, 1,837 were cancer patients, and 3,603 were non-cancer patients. Cumulative unadjusted mortality (determined by hospital records and an external death tracking system) was recorded at one day, three days, seven days, and 30 days. We used logistic regression to examine the risk of mortality 30 days after the ED visit after adjusting for confounders. RESULTS: In an unadjusted analysis, we found no statistically significant difference in the mortality of cancer vs. non-cancer patients at one day and three days. Significant differences in mortality were found at seven days (at lactate levels of <2 and 4+) and at 30 days (at all lactate levels) based on cancer status. After adjusting for age, gender, and acuity level, 30-day mortality rates were significantly higher at all levels of lactic acid (<2, 2-4, 4+) for patients with malignancy. CONCLUSION: When compared with non-cancer patients, cancer patients with elevated ED lactic acid levels had an increased risk of mortality at virtually all levels and time intervals we measured, although these differences only reached statistical significance in later time intervals (Day 7 and Day 30). Our results suggest that previous work in which lactate "cutoffs" are used to risk-stratify patients with respect to outcomes may be insufficiently sensitive for patients with cancer. Relatively low serum lactate levels may serve as a marker for serious illness in oncologic patients who present to the ED.

Objective: To determine whether results of the nasopharyngeal FilmArray respiratory panel (NP-FARP) influenced antibiotic decisions. Methods: We reviewed the medical records of nonintensive care unit (ICU) inpatients that had an NP-FARP performed at our institution between June 2013 and June 2014. The inpatient records were reviewed 48 hours after the NP-FARP for the following data: demographic information; NP-FARP, serum procalcitonin, and methicillin-resistant Staphylococcus aureus nasal swab (MRSA NS) results; antibiotics prior and post-48 hours of the NP-FARP result; and the current immunosuppression status. Clinical outcome data were not obtained. Patients were categorized into those who had a positive (+) or a negative (-) NP-FARP. We further subdivided these two categories into groups A, B, and C based on the antibiotic modifications 48 hours after their NP-FARP result. Group A included patients who were never initiated on antimicrobial therapy. Patients whose antibiotics were discontinued or deescalated were placed in group B. Patients with antibiotic escalation or continuation without change constituted group C. We compared and analyzed groups A, B, and C in the (+) and (-) NP-FARP cohorts. Results: A total of 545 patients were included. There were 143 (26%) patients with positive and 402 (74%) patients with negative NP-FARPs. Comparison of groups A, B, and C between those with a (+) and (-) NP-FARP were as follows: (+) A and (-) A, 28/143 (20%) and 84/402 (21%); (+) B and (-) B, 59/143 (41%) and 147/402 (37%); and (+) C and (-) C, 56/143 (39%) and 171/402 (43%), respectively. We found no statistically significant differences between groups (+) A versus (-) A, (+) B versus (-) B, and (+) C versus (-) C with respect to age, gender, MRSA NS result, procalcitonin result, or concurrent immunosuppression. Conclusion: In non-ICU inpatients, NP-FARP alone or in combination with procalcitonin or MRSA NS did not influence antibiotic decisions during the study period.

BACKGROUND: Outcomes have improved significantly in multiple myeloma (MM), but racial disparities in health care access and survival exist. A comprehensive analysis exploring MM care and racial disparities is warranted. METHODS: Patients with MM from 1991 to 2010 in the Surveillance, Epidemiology, and End Results-Medicare database were evaluated for racial trends in clinical myeloma-defining events (MDEs), the receipt of treatment (drugs and stem cell transplantation; [SCT]), the cost of care, and overall survival (OS). RESULTS: Among 35,842 patients, the frequency of all MDEs at diagnosis increased over time; whereas, in recent years (2006-2010), all MDEs with the exception of renal dialysis decreased. Blacks had highest rates for all MDEs except bone fractures, which were highest in whites. Over time, the proportion of patients who received any treatment, multiple agents, and SCT increased significantly, and the largest increase was observed in the receipt of immunomodulatory drugs and steroids. There was greater receipt of bortezomib and SCT among whites and blacks and higher receipt of immunomodulatory drugs among Hispanics and Asians (P < .001). Medicare claims were highest during first 6 months after MM diagnosis for blacks and at any time after MM diagnosis for Hispanics. Over time, Medicare claims increased most steadily for Hispanics (P < .001). Hypercalcemia, renal dysfunction, and bone fractures were associated with inferior OS. Blacks and Asians had superior OS compared with whites, but racial differences in OS became less pronounced during 2006 through 2010 (P = .182) compared with prior years (P < .01). Better OS was noted among patients who had higher median incomes. CONCLUSIONS: The current results indicate that there have been significant changes in the management of patients with MM over time and provide an in-depth understanding of the factors that may help explain racial disparities.

BACKGROUND: Skin cancer prevalence is well-characterized for white solid organ transplant recipients. Although the prevalence of skin cancer in non-white (Black, Asian, Hispanic) kidney transplant recipients (KTRs) has been assessed, no study has reported the prevalence of skin cancer in Native American (NA) KTRs. The aim of this study is to determine if the prevalence of skin cancer in NAKTRs is the same as in white KTRs. METHODS: We conducted a case-controlled retrospective review from a single transplant center. One hundred thirteen NAKTRs who received a transplant between 2001 and 2011 were age- and transplant-year matched with 113 white controls. RESULTS: The 226 KTRs consisted of 141 (62.4%) men and 85 (37.6%) women, with a mean age of 50.2 ± 10.8 years. There was no skin cancer found in NAKTRs prior to or post transplantation, while seven (6.2%) white KTRs had eight skin cancers prior to transplantation, and 28 (24.8%) white KTRs developed 66 skin cancers post transplantation. Twenty-two (19.5%) NAKTRs did not follow-up with dermatology at this institution. The median follow-up in NAKTRs was 3.3 years compared to 3.0 years in white KTRs. CONCLUSION: NAKTRs have a decreased prevalence of skin cancer compared to their white counterparts.

BACKGROUND: In total knee arthroplasty (TKA) for valgus knees, the decision to use a constrained implant is often made intraoperatively depending on the extent of soft tissue releases performed and residual soft tissue imbalance. The purpose of this study is to determine if preoperative radiographic criteria of valgus knees can predict the extent of soft tissue releases required and the level of constraint needed to balance the knee during TKA. METHODS: A single surgeon's 807 consecutive TKA standing hip-knee-ankle radiographs from 2007-2012 were analyzed. One hundred eighty-seven valgus knees were identified and annotated. Statistical univariate and multivariate analyses were performed for both outcomes, lateral release and articulation, to assess the association with risk factors of gender, age, and preoperative radiographic markers of valgus deformity. A P-value <.05 represented a significant difference between groups. RESULTS: Use of a constrained articulation was associated with increased valgus deformity (mechanical hip-knee-ankle angle, P < .0001) and extent of lateral soft tissue release (P < .0001). No relationship existed between the use of a constrained articulation and age or gender (P > .05). A preoperative anatomic tibiofemoral valgus angle of >16.8° was associated with the use of a constrained articulation during surgery. CONCLUSIONS: Our data demonstrate that preoperative radiographic characteristics of the valgus knee can be utilized to predict the extent of lateral soft tissue release and whether a constrained articulation will be required in TKA. This will provide surgeons with useful information to offer accurate preoperative counseling to patients and to ensure that the appropriate prosthetic parts are available during surgery.
RESUMO
Outcomes have improved considerably in multiple myeloma (MM), but disparities among racial-ethnic groups exist. Differences in utilization of novel therapeutics are likely contributing factors. We explored such differences from the SEER-Medicare database. A utilization analysis of lenalidomide, thalidomide, bortezomib, and stem cell transplant (SCT) was performed for patients diagnosed with MM between 2007 and 2009, including use over time, use by race, time-dependent trends for each racial subgroup, and survival analysis. A total of 5338 MM patients were included with median 2.4-year follow-up. Within the first year of MM diagnosis, utilization of lenalidomide, bortezomib, SCT, and more than one novel agent increased over time while utilization of thalidomide decreased. There was significantly lower utilization of lenalidomide among African-Americans (P < 0.01), higher thalidomide use among Hispanics and Asians (P < 0.01), and lower bortezomib use among Asians (P < 0.01). Hispanics had the highest median number of days to first dose of bortezomib (P = 0.02) and the lowest utilization of SCT (P < 0.01). Hispanics and Asians were the only groups without notable increases in lenalidomide and bortezomib use, respectively. SCT utilization increased over time for all except African-Americans. SCT use within the first year after diagnosis was associated with better overall survival (HR 0.52; 95% CI: 0.4-0.68), while bortezomib use was associated with inferior survival (HR 1.14; 95% CI 1.02-1.28). We noted considerable variability in MM therapeutics utilization with seeming inequity for racial-ethnic minorities. These trends should be considered to eliminate drug access and utilization disparities and achieve equitable benefit of therapeutic advances across all races.
