RESUMO

OBJECTIVES: Compare the feeding management practices in infants with cleft palate with and without Pierre Robin sequence (PRS) and determine if specific feeding difficulties or interventions predict delayed palate repair. DESIGN: Retrospective cross-sectional study. SETTING: Seventeen cleft palate teams contributed data. PATIENTS: 414 infants were included in this study: 268 infants with cleft palate only and 146 infants with cleft palate and PRS. PROCEDURES: Data were collected via parent interview and electronic health records. MAIN OUTCOME MEASURES: Outcomes for the primary objective included categorical data for: history of poor growth, feeding therapy, milk fortification, use of enteral feeding, and feeding difficulties. The outcome for the secondary objective was age in months at primary palate repair. RESULTS: Infants with PRS had a significantly higher prevalence of feeding difficulties (81% versus 61%) and poor growth (29% versus 15%) compared to infants with cleft palate only. Infants with PRS received all feeding interventions-including feeding therapy, milk fortification, and enteral feeding-at a significantly higher frequency. Infants with PRS underwent primary palate repair at a mean age of 13.55 months (SD = 3.29) which was significantly (P < .00001) later than infants with cleft palate only who underwent palate repair at a mean age of 12.05 months (SD = 2.36). Predictors of delayed palate repair included diagnosis of PRS as well as Hispanic ethnicity and a history of poor growth. CONCLUSIONS: These findings can be used to establish clinical directives focused on providing early, multimodal feeding interventions to promote optimal growth and timely palate repair for infants with PRS.

RESUMO

OBJECTIVE: To describe the impact of completing the CLEFT-Q appearance scales on patients with cleft lip and/or palate and to identify demographic and clinical characteristics and CLEFT-Q scores associated with reporting a negative impact. DESIGN: International cross-sectional survey. SETTING: Recruitment took place between October 2014 and November 2016 at 30 craniofacial clinics located in 12 countries. PATIENTS: Aged 8 to 29 years with cleft lip and/or palate. MAIN OUTCOME MEASURE(S): Participants were asked 4 questions to evaluate the impact of completing the field test version of a patient-reported outcome measure (the CLEFT-Q) that included 154 items, of which 79 (51%) asked about appearance (of the face, nose, nostrils, teeth, lips, jaws, and cleft lip scar). RESULTS: The sample included 2056 participants. Most participants liked answering the CLEFT-Q (88%) and the appearance questions (82%). After completing the appearance scales, most participants (77%) did not feel upset or unhappy about how they look, and they felt the same (67%) or better (23%) about their appearance after completing the questionnaire. Demographic and clinical variables associated with feeling unhappy/upset or worse about how they look included country of residence, female gender, more severe cleft, anticipating future cleft-specific surgeries, and reporting lower (ie, worse) scores on CLEFT-Q appearance and health-related quality-of-life scales. CONCLUSION: Most participants liked completing the CLEFT-Q, but a small minority reported a negative impact. When used in clinical practice, CLEFT-Q scale scores should be examined as soon as possible after completion in order that the clinical team might identify patients who might require additional support.

RESUMO

BACKGROUND: Patients with cleft lip and/or palate can undergo numerous procedures to improve appearance, speech, dentition and hearing. We developed a cleft-specific patient-reported outcome instrument to facilitate rigorous international measurement and benchmarking. METHODS: Data were collected from patients aged 8-29 years with cleft lip and/or palate at 30 hospitals in 12 countries between October 2014 and November 2016. Rasch measurement theory analysis was used to refine the scales and to examine reliability and validity. Normative CLEFT-Q values were computed for age, sex and cleft type. RESULTS: Analysis led to the refinement of an eating and drinking checklist and 12 scales measuring appearance (of the face, nose, nostrils, teeth, lips, jaws and cleft lip scar), health-related quality of life (psychological, social, school, speech distress) and speech function. All scales met the requirements of the Rasch model. Analysis to explore differential item functioning by age, sex and country provided evidence to support the use of a common scoring algorithm for each scale for international use. Lower (worse) scores on CLEFT-Q scales were associated with having a speech problem, being unhappy with facial appearance, and needing future cleft-related treatments, providing evidence of construct validity. Normative values for age, sex and cleft type showed poorer outcomes associated with older age, female sex and having a visible cleft. INTERPRETATION: The CLEFT-Q represents a rigorously developed instrument that can be used internationally to collect and compare evidence-based outcomes data from patients aged 8-29 years of age with cleft lip and/or palate.

RESUMO

Sino-orbital fungal infection is a rare, but life-threatening disease seen mainly in immunocompromised patients. While initial clinical impression may vary, dacryocystitis has rarely been described as the initial presenting sign. The authors present 2 pediatric cases of dacryocystitis as the initial sign of invasive fungal sinusitis. To their knowledge, this presenting sign has not been previously reported in the pediatric population. Management strategies and outcomes are discussed.

RESUMO

OBJECTIVE: Our aim was to evaluate dental/orthodontic outcomes for patients who underwent recombinant human bone morphogenic protein (rhBMP-2) alveolar cleft repair and to examine parental satisfaction following the procedure. Design Retrospective review. Setting Tertiary children's hospital. Participants Parents, dentists, and orthodontists completed satisfaction questionnaires. Main Outcome Measures Parent, dentist, and orthodontist satisfaction with the use of rhBMP-2 in alveolar cleft repair. Results Parent response rate was 71.4% (30/42). The dentist response rate was 60% (18/30). The orthodontist response rate was 53.3% (16/30). Parent and patient satisfaction was 93.3% and 83.3%, respectively. Of dentist respondents, 55.6% reported that the bone quality and alveolar ridge mucosal repair allowed for dental treatment. Of orthodontist respondents, 87.5% reported the graft enabled treatment, and 73.3% felt the graft prevented tooth root exposure and resorption. Conclusions Parents, dentists, and orthodontists are satisfied with outcomes when rhBMP-2 is used for alveolar cleft repair. The bone formed was reported as adequate to support dental and orthodontic treatment in most cases with few complications. Because of safety concerns over the use of this product in an off-label manner, further controlled studies are warranted.

RESUMO

BACKGROUND: AMRA (adverse metabolic or muscular reaction to anesthesia) reports submitted to The North American Malignant Hyperthermia Registry of the Malignant Hyperthermia Association of the United States from 1987 to 2006 revealed a 2.7% cardiac arrest and a 1.4% death rate for 291 malignant hyperthermia (MH) events. We analyzed 6 years of recent data to update MH cardiac arrest and death rates, summarized characteristics associated with cardiac arrest and death, and documented differences between early and recent cohorts of patients in the MH Registry. We also tested whether the available data supported the hypothesis that risk of dying from an episode of MH is increased in patients with inadequate temperature monitoring. METHODS: We included U.S. or Canadian reports of adverse events after administration of at least 1 anesthetic drug, received between January 1, 2007, and December 31, 2012, with an MH clinical grading scale rank of "very likely MH" or "almost certain MH." We excluded reports that, after review, were judged to be due to pathologic conditions other than MH. We analyzed patient demographics, family and patient anesthetic history, anesthetic management including temperature monitoring, initial dantrolene dose, use of cardiopulmonary resuscitation, MH complications, survival, and reported molecular genetic DNA analysis of RYR1 and CACNA1S. A one-sided Cochran-Armitage test for proportions evaluated associations between mode of monitoring and mortality. We used Miettinen and Nurminen's method for assessing the relative risk of dying according to monitoring method. We used the P value of the slope to evaluate the relationship between duration of anesthetic exposure before dantrolene administration and peak temperature. We calculated the relative risk of death in this cohort compared with our previous cohort by using the Miettinen and Nurminen method adjusted for 4 comparisons. RESULTS: Of 189 AMRA reports, 84 met our inclusion criteria. These included 7 (8.3%) cardiac arrests, no successful resuscitations, and 8 (9.5%) deaths. Of the 8 patients who died, 7 underwent elective surgeries considered low to intermediate risk. The average age of patients who died was 31.4 ± 16.9 years. Five were healthy preoperatively. Three of the 8 patients had unrevealed MH family history. Four of 8 anesthetics were performed in freestanding facilities. In those who died, 3 MH-causative RYR1 mutations and 3 RYR1 variants likely to have been pathogenic were found in the 6 patients in whom RYR1 was examined. Compared to core temperature monitoring, the relative risk of dying with no temperature monitoring was 13.8 (lower limit 2.1). Compared to core temperature monitoring, the relative risk of dying with skin temperature monitoring was 9.7 (1.5). Temperature monitoring mode best distinguished patients who lived from those who died. End-tidal CO2 was the worst physiologic measure to distinguish patients who lived from those who died. Longer anesthetic exposures before dantrolene were associated with higher peak temperatures (P = 0.00056). Compared with the early cohort, the recent cohort had a higher percentage of MH deaths (4/291 vs 8/84; relative risk = 6.9; 95% confidence interval, 1.7-28; P = 0.0043 after adjustment for 4 comparisons). CONCLUSIONS: Despite a thorough understanding of the management of MH and the availability of a specific antidote, the risk of dying from an MH episode remains unacceptably high. To increase the chance of successful MH treatment, the American Society of Anesthesiologists and Malignant Hyperthermia Association of the U.S. monitoring standards should be altered to require core temperature monitoring for all general anesthetics lasting 30 minutes or longer.

RESUMO

BACKGROUND: Maintenance of function during cancer treatment is important to older adults. Characteristics associated with pretreatment life-space mobility and changes during non-small cell lung cancer (NSCLC) treatment remain unknown. METHODS: This mixed methods cohort study recruited adults age ≥65 with advanced NSCLC starting palliative chemotherapy, immunotherapy, and/or targeted therapy from a Comprehensive Cancer Center, Veterans Affairs, and safety-net clinic. Patients completed geriatric assessments including Life-Space Assessment (LSA) pretreatment and at 1, 2, 4, and 6 months after treatment initiation. LSA scores range from 0 to 120 (greater mobility); LSA <60 is considered restricted. We used mixed-effects models to examine pretreatment LSA, change from 0 to 1 month, and change from 1 to 6 months. A subgroup participated in semistructured interviews pretreatment and at 2 and 6 months to understand the patient experience of life-space change. For each interview participant, we created joint displays of longitudinal LSA scores juxtaposed with illustrative quotes. RESULTS: Among 93 patients, median age was 73 (range 65-94). Mean pretreatment LSA score was 67.1. On average, LSA declined 10.1 points from pretreatment to 1 month and remained stable at 6 months. Pretreatment LSA score was associated with several demographic, clinical, geriatric assessment, and symptom characteristics. LSA decline at 1 month was greater among patients with high anxiety (slope = -12.6 vs. -2.3, p = 0.048). Pretreatment body mass index <21 kg/m2 was associated with LSA improvement from 1 to 6 months (slope = 4.1 vs. -0.04, p = 0.003). Joint displays illustrated the impact of different life-space trajectories on patients' lives in their words. CONCLUSION: Older adults with NSCLC have low pretreatment life space with many developing restricted life space during treatment. Incorporating life-space assessments into clinical cancer care may help older adults concretely visualize how treatment might impact their daily function to allow for informed decision making and identify early changes in mobility to implement supportive interventions.

RESUMO

BACKGROUND: The FACE-Q Craniofacial Module is a patient-reported outcome measure designed for patients aged 8 to 29 years with conditions associated with a facial difference. In part 1, we describe the psychometric findings for the original CLEFT-Q scales tested in patients with cleft and noncleft facial conditions. The aim of this study was to examine psychometric performance of new FACE-Q Craniofacial Module scales. METHODS: Data were collected between December 2016 and December 2019 from patients aged 8 to 29 years with conditions associated with a visible or functional facial difference. Rasch measurement theory (RMT) analysis was used to examine psychometric properties of each scale. Scores were transformed from 0 (worst) to 100 (best) for tests of construct validity. RESULTS: 1495 participants were recruited with a broad range of conditions (e.g., birthmarks, facial paralysis, craniosynostosis, craniofacial microsomia, etc.) RMT analysis resulted in the refinement of 7 appearance scales (Birthmark, Cheeks, Chin, Eyes, Forehead, Head Shape, Smile), two function scales (Breathing, Facial), and an Appearance Distress scale. Person separation index and Cronbach alpha values met criteria. Three checklists were also formed (Eye Function, and Eye and Face Adverse Effects). Significantly lower scores on eight of nine scales were reported by participants whose appearance or functional difference was rated as a major rather than minor or no difference. Higher appearance distress correlated with lower appearance scale scores. CONCLUSION: The FACE-Q Craniofacial Module scales can be used to collect and compare patient reported outcomes data in children and young adults with a facial condition.

RESUMO

BACKGROUND: We analyzed cases of malignant hyperthermia (MH) reported to the North American MH Registry for clinical characteristics, treatment, and complications. METHODS: Our inclusion criteria were as follows: AMRA (adverse metabolic/musculoskeletal reaction to anesthesia) reports between January 1, 1987 and December 31, 2006; "very likely" or "almost certain" MH as ranked by the clinical grading scale; United States or Canadian location; and more than one anesthetic drug given. An exclusion criterion was pathology other than MH; for complication analysis, patients with unknown status or minor complications attributable to dantrolene were excluded. Wilcoxon rank sum and Pearson exact chi(2) tests were applied. A multivariable model of the risk of complications from MH was created through stepwise selection with fit judged by the Hosmer-Lemeshow statistic. RESULTS: Young males (74.8%) dominated in 286 episodes. A total of 6.5% had an MH family history; 77 of 152 patients with MH reported >or=2 prior unremarkable general anesthetics. In 10 cases, skin liquid crystal temperature did not trend. Frequent initial MH signs were hypercarbia, sinus tachycardia, or masseter spasm. In 63.5%, temperature abnormality (median maximum, 39.1 degrees C) was the first to third sign. Whereas 78.6% presented with both muscular abnormalities and respiratory acidosis, only 26.0% had metabolic acidosis. The median total dantrolene dose was 5.9 mg/kg (first quartile, 3.0 mg/kg; third quartile, 10.0 mg/kg), although 22 patients received no dantrolene and survived. A total of 53.9% received bicarbonate therapy. Complications not including recrudescence, cardiac arrest, or death occurred in 63 of 181 patients (34.8%) with MH. Twenty-one experienced hematologic and/or neurologic complications with a temperature <41.6 degrees C (human critical thermal maximum). The likelihood of any complication increased 2.9 times per 2 degrees C increase in maximum temperature and 1.6 times per 30-minute delay in dantrolene use. CONCLUSION: Elevated temperature may be an early MH sign. Although increased temperature occurs frequently, metabolic acidosis occurs one-third as often. Accurate temperature monitoring during general anesthetics and early dantrolene administration may decrease the 35% MH morbidity rate.

RESUMO

Military forces and the recreational industry rely on the repellent properties of permethrin-treated fabrics and N,N-diethyl-meta-toluamide (deet)-based lotions to provide protection from disease vectors and hematophagous organisms. Concerns regarding efficacy have been raised as pyrethroid resistance becomes more common and recent publications present contradictory conclusions. In this preliminary study, consenting volunteers were exposed to pyrethroid-susceptible and pyrethroid-resistant Aedes aegypti strains while wearing sleeves of untreated or permethrin-treated army uniform fabric as well as with untreated or deet-treated exposed forearms. Deet was nearly 100% effective against both susceptible and resistant strains. However, permethrin treatment provided no significant protection against the resistant Puerto Rico strain relative to untreated control sleeves. These results confirm that pyrethroid-resistant vectors can negate the efficacy of permethrin-treated uniforms. Additional testing with resistant field strains is needed to better understand the risk to service members.

RESUMO

Precise discrimination of tumor from normal tissues remains a major roadblock for therapeutic efficacy of chimeric antigen receptor (CAR) T cells. Here, we perform a comprehensive in silico screen to identify multi-antigen signatures that improve tumor discrimination by CAR T cells engineered to integrate multiple antigen inputs via Boolean logic, e.g., AND and NOT. We screen >2.5 million dual antigens and ∼60 million triple antigens across 33 tumor types and 34 normal tissues. We find that dual antigens significantly outperform the best single clinically investigated CAR targets and confirm key predictions experimentally. Further, we identify antigen triplets that are predicted to show close to ideal tumor-versus-normal tissue discrimination for several tumor types. This work demonstrates the potential of 2- to 3-antigen Boolean logic gates for improving tumor discrimination by CAR T cell therapies. Our predictions are available on an interactive web server resource (antigen.princeton.edu).

RESUMO

OBJECTIVE: To make recommendations on the identification, routine evaluation, and management of fetuses at risk for airway compromise at delivery. METHODS: Recommendations are based on expert opinion by members of the International Pediatric Otolaryngology Group (IPOG). A two-iterative Delphi method questionnaire was distributed to all members of the IPOG and responses recorded. The respondents were given the opportunity to comment on the content and format of the survey, which was modified for the second round. "Consensus" was defined by >80% respondent affirmative responses, "agreement" by 51-80% affirmative responses, and "no agreement" by 50% or less affirmative responses. RESULTS: Recommendations are provided regarding etiologies of perinatal airway obstruction, imaging evaluation, adjunct evaluation, multidisciplinary team and decision factors, micrognathia management, congenital high airway obstruction syndrome management, head and neck mass management, attended delivery procedure, and delivery on placental support procedure. CONCLUSIONS: Thorough evaluation and thoughtful decision making are required to optimally balance fetal and maternal risks/benefits.

RESUMO

Plexiform fibrohistiocytic tumor is a low-grade soft tissue malignancy that can at times be difficult to differentiate from the less biologically aggressive cellular neurothekeoma. The two entities, which may display identical clinical and histological features, cannot be distinguished by immunohistochemical or molecular diagnostic means. Electron microscopy may enable the accurate identification of problematic examples and thus aid in resolving these occasionally occurring diagnostic dilemmas. To illustrate typical variations in the ultrastructural appearance of plexiform fibrohistiocytic tumor, the authors present two diagnostically noncontroversial examples, and to demonstrate the potential diagnostic utility of electron microscopy in this setting, they present an example of plexiform fibrohistiocytic tumor that could not otherwise have been distinguished from cellular neurothekeoma.

RESUMO

Signaling through the insulin-like growth factor-I receptor (IGF-IR) is implicated in cellular proliferation, apoptosis, carcinogenesis, metastasis, and resistance to cytotoxic cancer therapies. Targeted disruption of IGF-IR signaling combined with cytotoxic therapy may therefore yield improved anticancer efficacy over conventional treatments alone. In this study, a fully human anti-IGF-IR monoclonal antibody A12 (ImClone Systems, Inc., New York, NY) is examined as an adjunct to radiation therapy. IGF-IR expression is shown for a diverse cohort of cell lines, whereas targeted IGF-IR blockade by A12 inhibits IGF-IR phosphorylation and activation of the downstream effectors Akt and mitogen-activated protein kinase. Anchorage-dependent proliferation and xenograft growth is inhibited by A12 in a dose-dependent manner, particularly for non-small cell lung cancer lines. Clonogenic radiation survival of H226 and H460 cells grown under anchorage-dependent conditions is impaired by A12, demonstrating a radiation dose-enhancing effect for IGF-IR blockade. Postradiation anchorage-independent colony formation is inhibited by A12 in A549 and H460 cells. In the H460 xenograft model, combining A12 and radiation significantly enhances antitumor efficacy compared with either modality alone. These effects may be mediated by promotion of radiation-induced, double-stranded DNA damage and apoptosis as observed in cell culture. In summary, these results validate IGF-IR signal transduction blockade as a promising strategy to improve radiation therapy efficacy in human tumors, forming a basis for future clinical trials.

RESUMO

BACKGROUND: Measuring the patient perspective is important in evaluating outcomes of cleft care. Understanding how treatment outcomes vary depending on cleft type may allow for better planning of treatments, setting of expectations, and more accurate benchmarking efforts. The CLEFT-Q is a patient-reported outcome measure for patients with cleft lip and/or palate. METHODS: The 12 CLEFT-Q scales measuring appearance (i.e., face, nose, nostrils, lips, cleft lip scar, teeth, and jaws), function (i.e., speech), and health-related quality of life (i.e., psychological, school, social, and speech-related distress) were field tested in a cross-sectional study in 30 centers in 12 countries. Patients with cleft lip and/or cleft palate aged 8 to 29 years were recruited from clinical settings. Differences in CLEFT-Q scores by cleft subtypes were evaluated using one-way analysis of variance or Kruskal-Wallis H tests, with Tukey or Dunn procedure with Bonferroni corrections post hoc analyses, respectively. Scores are presented using radar charts to visualize all outcomes simultaneously. RESULTS: The field test included 2434 patients. Scores on all CLEFT-Q scales varied significantly with cleft subtype. Patients with unilateral or bilateral cleft lip and/or palate scored lower on all appearance scales compared with patients with cleft palate or unilateral incomplete cleft lip. Scores on the speech function and speech-related distress scales decreased with each progressive group in the Veau classification. Patients with complete bilateral cleft lip and palate scored lowest on the social, school, and psychological scales. CONCLUSIONS: Patient-reported outcomes measured with the CLEFT-Q vary significantly with cleft type. Visualizing multiple outcomes simultaneously with radar charts allows for an understanding of a patient's overall status in a single graph.

RESUMO

BACKGROUND: The authors determined associated cardiac arrest and death rates in cases from Canada and the United States as reported to The North American Malignant Hyperthermia (MH) Registry and analyzed factors associated with a higher risk of poor outcomes. METHODS: The authors searched the database for AMRA (adverse metabolic/musculoskeletal reaction to anesthesia) reports with inclusion criteria as follows: event date between January 1, 1987, and December 31, 2006; "very likely" or "almost certain" MH as ranked by MH Clinical Grading Scale; location in Canada or the United States; and one or more anesthetic agents given. The exclusion criterion was a pathologic condition other than MH independently judged by the authors. Severe MH outcomes were analyzed as regards clinical history and presentation, using Wilcoxon rank sum tests for continuous variables and Pearson exact chi-square tests for categorical variables. A Bonferroni correction adjusted for multiple comparisons. RESULTS: Of 291 events, 8 (2.7%) resulted in cardiac arrests and 4 (1.4%) resulted in death. The median age in cases of cardiac arrest/death was 20 yr (range, 2-31 yr). Associated factors were muscular build (odds ratio, 18.7; P = 0.0016) and disseminated intravascular coagulation (odds ratio, 49.7; P < 0.0001). Increased risk of cardiac arrest/death was related to a longer time period between anesthetic induction and maximum end-tidal carbon dioxide (216 vs. 87 min; P = 0.003). Unrelated factors included patient or family history, anesthetic management, and the MH episode. CONCLUSIONS: Modern US anesthetic practice did not prevent MH-associated cardiac arrest and death in predominantly young, healthy patients undergoing low- to intermediate-risk surgical procedures.
