RESUMO

BACKGROUND: Refractory obstructive sleep apnea (OSA) is a common condition in children with medical comorbidities, leading to a significant impact on quality of life. Drug-induced sleep endoscopy (DISE) has become the standard of care in identifying the levels of obstruction in children with refractory OSA. Epiglottopexy has been shown to improve OSA symptoms in adults and healthy children with epiglottic prolapse in a few studies, with minimal long-term complications. The objective of our study was to evaluate the role of epiglottopexy in children with refractory OSA. METHODS: A retrospective chart review of children with refractory OSA who were found to have epiglottic prolapse on DISE, and underwent epiglottopexy between January 2018 and November 2021 at a pediatric tertiary care hospital. RESULTS: 42 patients (age 8.1 ± 5.1 years) met inclusion criteria. Thirty patients (71.4 %) suffered from neurodevelopmental disease or congenital syndrome, and 14 patients (33.3 %) were gastrostomy-tube dependent. All patients had at least one prior surgical procedure to address their OSA. Thirty-six patients (85.7 %) were diagnosed with refractory OSA by polysomnography prior to surgery, with an average apnea-hypopnea index (AHI) of 12.4 ± 9.7/h. Forty patients (95.2 %) required an additional procedure in conjunction with epiglottopexy including lingual tonsillectomy (n = 27, 64.3 %), supraglottoplasty (n = 14, 33.3 %), tonsillectomy with or without revision adenoidectomy (n = 9, 21.4 %) and tongue base suspension (n = 1, 2.4 %). Twenty-one patients had repeated polysomnography; 4 patients were found to have residual severe OSA post-operatively (average AHI 17.4 ± 11.4/h), while the remaining patients demonstrated clinical improvement and a significant reduction in OSA severity, with an average AHI of 1.5 ± 2.2/h. Regression analysis identified pre-operative oxygen nadir <75 % to be associated with residual OSA postoperatively. Following surgery, 7 patients were found to have new-onset or worsening dysphagia, 6 of whom were diagnosed with complex medical comorbidities. CONCLUSIONS: Epiglottopexy, as part of multi-level airway surgery, is associated with a significant improvement in the severity of refractory OSA. Dysphagia may complicate the post-operative course, particularly in children with medical comorbidities.

RESUMO

MicroRNAs applications were vastly studied throughout the years, spanning from potential cancer biomarkers to targeted therapies for various diseases. Out of these utilizations, this paper focuses on their role in male infertility. Approximately 10-15% of worldwide couples are affected by infertility. Out of these, 50% are due to male determinants. The majority of cases still have an undetermined cause. Previous studies have found that the aberrant expression of microRNAs could be linked to certain reproductive dysfunctions in males. Further on, this study looked into the most recent literature published on this subject in order to assess the connection between the up-/down-regulation of various microRNAs and the roles they play in male infertility. MicroRNAs were found to be abundant and stable in the seminal liquid, which led to a facile identification using regular RNA detection methods. It was observed that the concentration of microRNAs in semen was modified in the case of patients suffering from asthenozoospermia and azoospermia. Moreover, idiopathic male infertility was associated with a single nucleotide polymorphism of the microRNA binding site. Future studies should focus their attention on discovering future treatments against male infertility targeting specific microRNAs and also on developing new and improved contraceptive methods.

RESUMO

Children with congenital central hypoventilation syndrome (CCHS) have a PHOX2B mutation-induced control of breathing deficit necessitating artificial ventilation as life support. A subset of CCHS families seek phrenic nerve-diaphragm pacing (DP) during sleep with the goal of tracheal decannulation. Published data regarding DP during sleep as life support in the decannulated child with CCHS and related airway dynamics in young children are limited. We report a series of 3 children, ages 3.3-4.3 years, who underwent decannulation. Sleep endoscopy performed during DP revealed varied (oropharynx, supraglottic, glottic, etc.) levels of complete airway obstruction despite modification of pacer settings. Real-time analysis of end tidal CO2 and SpO2 confirmed inadequate gas exchange. Because the families declined re-tracheostomy, all 3 patients rely on noninvasive mask ventilation as a means of life support while asleep. These results emphasize the need for extreme caution in proceeding with tracheal decannulation in young children with CCHS who expect to use DP during sleep as life support. Parents and patients should anticipate that they will depend on noninvasive mask ventilation (rather than DP) during sleep after undergoing decannulation. This information may improve management and guide expectations regarding potential decannulation in young paced children with CCHS.

RESUMO

BACKGROUND: The best treatment for patients with advanced non-small cell lung cancer (NSCLC) and a poor performance status is not well defined. In this phase 2 trial, patients were randomized to receive treatment with either single-agent pemetrexed or 1 of 2 combination regimens. METHODS: Patients with newly diagnosed, histologically confirmed nonsquamous NSCLC and an Eastern Cooperative Oncology Group (ECOG) performance status of 2 were stratified by age and serum albumin level and were randomized (1:1:1) to 1 of 3 regimens: pemetrexed (arm 1), pemetrexed and bevacizumab (arm 2), or pemetrexed, carboplatin, and bevacizumab (arm 3). The response to treatment was assessed every 2 cycles; responding and stable patients continued treatment until progression or unacceptable toxicity. RESULTS: One hundred seventy-two patients were randomized, 162 patients began the study treatment, and 146 patients completed 2 cycles and were evaluated for their response. The median progression-free survival (PFS) was 2.8 months in arm 1, 4.0 months in arm 2, and 4.8 months in arm 3. The overall response rates were 15% in arm 1, 31% in arm 2, and 44% in arm 3. The overall survival was similar in the 3 treatment arms. All 3 regimens were relatively well tolerated. Patients receiving bevacizumab had an increased incidence of hypertension, proteinuria, and bleeding episodes, but most events were mild or moderate. CONCLUSIONS: All 3 regimens were feasible for patients with advanced NSCLC and an ECOG performance status of 2. The addition of bevacizumab to pemetrexed increased the overall response rate. The efficacy of pemetrexed/carboplatin/bevacizumab (median PFS, 4.8 months) approached the prespecified study PFS goal of 5 months. Larger studies will be necessary to define the role of bevacizumab in addition to standard pemetrexed and carboplatin in this population. Cancer 2018;124:1982-91. © 2018 American Cancer Society.

RESUMO

This Phase II trial evaluated the efficacy of bendamustine, bortezomib and rituximab in patients with previously untreated low-grade lymphoma. Eligible patients had low grade lymphoma with no previous systemic disease treatment. Treatment for all patients was given in 28-day cycles for a maximum of 6 cycles. Patients received rituximab 375 mg/m2 intravenously (IV) on days 1, 8 and 15 of cycle 1 and day 1 of cycles 2-6; bendamustine 90 mg/m2 IV on days 1 and 2; and bortezomib 1·6 mg/m2 IV on days 1, 8 and 15. Patients were permitted to begin maintenance treatment with rituximab 6 months after completion of study treatment and after 6-month follow-up assessments had been conducted. Fifty-four eligible patients were enrolled. The most common grade 3/4 toxicities were leucopenia (28%), neutropenia (30%) and lymphopenia (17%). There were no treatment-related deaths and 1 unrelated death on study (embolic stroke). The overall response rate was 94% for all patients. The median follow-up was 54 months. Kaplan-Meier estimates of progression-free survival and overall survival at 36 months were 75% and 88%, respectively. The treatment regimen was well tolerated and produced high response rates. Further study of this regimen in patients with previously untreated lymphoma is warranted.

RESUMO

PURPOSE: Airway management in neonates with Pierre Robin sequence (PRS) can be challenging. The goal was to describe the algorithm developed by the authors over the past 8 years. METHODS: A retrospective case series analyzing airway management in neonates with PRS admitted to the neonatal intensive care unit at a tertiary care pediatric hospital was performed. The utility of the proposed algorithm for airway management incorporating more consistent use of polysomnography (PSG), and airway assessment was assessed. RESULTS: A total of 31 neonates with PRS (12 men, 19 women) with a mean gestational age of 38.2 weeks were analyzed. Thirteen (41.9%) patients had a named syndrome, chromosomal abnormality, or global delay. Twenty (64.5%) patients had pre-intervention PSG, and severe obstructive sleep apnea with an apnea-hypopnea index (AHI) ≥ 10 events/hour was identified in 19 (95.0%). Mandibular distraction osteogenesis was performed in 18 (58.1%) patients, and improved the AHI on post-operative PSGs. Direct assessment of the upper and lower airways was performed in 19 patients, and 13 (68.4%) were found to have secondary airway pathology. Presence of a concomitant syndrome was significantly associated with need for tracheostomy. CONCLUSION: The algorithm differs from previous ones in that it relies on rigorous pre- and post-intervention PSG (including with a nasopharyngeal airway), as well as that it allows flexibility between treatment options given the whole-patient clinical scenario and endoscopic findings. Results from these studies may be integrated to stratify patients into those who are most likely to benefit from conservative interventions or surgical procedures.

RESUMO

BACKGROUND: This phase I/II study was designed to determine the maximum tolerated dose of tivantinib in combination with standard dose FOLFOX for the treatment of patients with advanced solid tumors and to evaluate the safety and efficacy of this combination for patients with previously untreated metastatic adenocarcinoma of the distal esophagus, gastroesophageal (GE) junction, or stomach. METHODS: Patients with advanced solid tumors for which FOLFOX would be appropriate chemotherapy received escalating doses of tivantinib BID (days 1-14) in a standard 3 + 3 design in phase I. In phase II, patients with advanced GE cancer received standard FOLFOX day 1 and tivantinib (360 mg PO BID) days 1-14 of each 2-week cycle. Restaging occurred every four cycles. The primary phase II endpoint was response rate (RR). RESULTS: Forty-nine patients were enrolled (15 on phase I and 34 on phase II). The expansion dose was established as tivantinib 360 mg BID in combination with FOLFOX. Thirty-two phase II patients were treated for a median of eight cycles (range, 1-38), with an overall RR of 38%. Treatment-related toxicities included neutropenia, fatigue, diarrhea, nausea, and peripheral neuropathy. Median progression-free survival (PFS) was 6.1 hmonths with a median time to progression of 7.0 months. Median overall survival was 9.6 months. Two patients remain on study at the time of this analysis. CONCLUSIONS: The combination treatment of tivantinib plus FOLFOX in patients with advanced GE cancer showed a response and PFS in the range of historical controls for first-line FOLFOX therapy. However, two patients had extended time on study treatment (36 and 45 cycles) at the time of data cutoff.

RESUMO

BACKGROUND: This phase II study combined aflibercept with preoperative chemoradiation for patients with stage II/III rectal cancer, followed by mFOLFOX6/aflibercept. METHODS: Patients received preoperative 5-FU (days 1-43), radiation (weeks 1-6), and aflibercept (days 1-15) each 28 day cycle for 6 weeks. Six weeks following the last aflibercept dose, patients underwent surgical resection. Four cycles of mFOLFOX6 plus aflibercept began 8 weeks after surgery. RESULTS: Common treatment-related toxicities included diarrhea, fatigue, and mucositis. The pCR rate was 23%. DISCUSSION: Afilbercept plus 5-FU-based chemoradiation was tolerated in patients with localized rectal cancer and showed a pCR rate within range of historical data.

RESUMO

BACKGROUND: AUY922 is an inhibitor of heat shock protein 90 (Hsp90). Hsp90 inhibitors induce kit degradation in preclinical gastrointestinal stromal tumor (GIST) models. This trial was designed to determine the progression-free survival (PFS) of patients with GIST refractory to or intolerant of imatinib and sunitinib. METHODS: Eligible patients received AUY922 70 mg/mg(2) by intravenous (IV) infusion on days 1, 8, and 15 of 21-day cycles. Treatment continued until progression or unacceptable toxicity. RESULTS: Between December 2011 and January 2015, 25 patients were enrolled (median age, 63 years; 56% male) and received a median of 2 cycles (range: 1-12) of AUY922 treatment. Thirty-four patients were planned, but enrollment was stopped early due to slow accrual. Median PFS was 3.9 months (95% CI: 2.5, 5.3) and median OS was 8.5 months (95% CI: 5.2, 16.7). Radiographic response was evaluated in 21 patients; one patient achieved PR (4%) with another 15 having best response of stable disease (60%). The most common treatment-related adverse event was diarrhea (60% all grades). Reversible ocular toxicities that resulted in drug hold (24%) or reduction (8%) were also observed. CONCLUSION: AUY922 produced a median PFS which compares favorably to historical controls of placebo (6 weeks) for patients refractory to treatment with imatinib. While diarrhea and ocular toxicities were common, the majority of patients received treatment until disease progression.

RESUMO

BACKGROUND: The prevalence of ventricular septal defects (VSDs), a birth defect in which there is an opening in the wall that separates the left and right ventricles of the heart, seemed to be substantially higher in Delaware compared with the National Birth Defects Prevention Network (NBDPN). The Delaware Birth Defects Registry (BDR) noted their high prevalence of VSDs in comparison with other states. METHODS: A subset of children with a VSD born in 2007 through 2010 was identified from the complete reportable statewide defect list that the BDR creates each year. VSDs were categorized by type of VSD (muscular, perimembranous, conotruncal, or atrioventricular septal defect), by either isolated or complex, and then by spontaneously closed, surgically closed, open but clinically insignificant, lost to follow-up, fetal or neonatal death. RESULTS: The BDR team found a prevalence of VSD of 83.4 per 10,000 including fetal/neonatal deaths. Excluding fetal and neonatal deaths the prevalence was 78.7 per 10,000 live births. Excluding small muscular VSDs, the prevalence in Delaware falls to 25.7 per 10,000. CONCLUSION: The BDR team chose to include all babies with all types of VSDs. Using these criteria Delaware's prevalence of 78.7 was higher than that reported by other states (whose prevalence ranges from 1.6 to 70.0 per 10,000 live births) (National Birth Defects Prevention Network, ). Delaware's prevalence is similar to other states when small muscular VSDs are excluded. Birth Defects Research (Part A) 106:888-893, 2016. © 2016 Wiley Periodicals, Inc.

RESUMO

Introduction The PI3 kinase (PI3K) pathway is a commonly dysregulated pathway in cancers and is an attractive target for antitumor therapy. BEZ235 is a potent, highly specific and selective dual PI3K/mTOR inhibitor. Methods Patients were enrolled in a 3 + 3 dose escalation design to determine the maximum tolerated dose (MTD), toxicities, and pharmacokinetics (PK) of BEZ235 when administered twice-daily as an oral sachet. For intrapatient PK comparison, patients were to receive a lead in of the total daily dose in a QD schedule for the first 8 days of the initial 28 day cycle. Patients continued treatment until unacceptable toxicity or disease progression occurred. Results Thirty-three patients received BEZ235. Initial dose levels of 200 and 400 mg BID had no DLTs. At the 600 mg BID dose level with 1200 mg QD lead in dose two DLTs of grade 3 mucositis occurred early in the first treatment cycle, the lead-in QD dosing was eliminated. Fatigue and mucositis limited dosing at 600 mg BID in subsequent patients. The 400 mg BID dose level was re-explored, with DLTs of grade 3 hyperglycemia, dehydration, fatigue, and grade 3 thrombocytopenia. Twelve patients were enrolled at an intermediate dose of 300 mg BID; a grade 3 mucositis DLT was reported in 1 patient, and this dose was declared the MTD. Preliminary PK data demonstrate a consistent increase in PK parameters (Cmax and AUC) with dose level compared to QD dosing. Fifteen patients experienced stable disease as their best response, including 10 (colorectal [4 patients], endometrial [3 patients], carcinoid NOS, pancreas, and melanoma) who had disease control for ≥16 weeks. Conclusions The recommended dose of BEZ235 administered BID as an oral sachet formulation is 300 mg BID. Toxicities seen have been reported for other dual PI3K/mTOR inhibitors.

RESUMO

BACKGROUND: This phase I study determined the maximum tolerated dose (MTD) of AUY922 with capecitabine in advanced solid tumors. METHODS: Capecitabine 1000 mg/m(2) PO BID was administered with escalating doses of AUY922 IV; the MTD of AUY922 was combined with capecitabine 1250 mg/m(2) (DL6). RESULTS: 23 patients were treated at 5 dose levels (22 mg/m(2)-70 mg/m(2)). No DLTs were observed until DL6 (grade 3 diarrhea). Reversible vision darkening was seen in 26%. Four patients had partial response; 2 previously progressed on fluorouracil. Eight patients had stable disease (median 25.5 weeks). CONCLUSION: AUY922 plus capecitabine was well-tolerated up to 70 mg/m(2) with encouraging preliminary efficacy.

RESUMO

Chondrodysplasia punctata (CDP) is a rare congenital syndrome characterized by aberrant, punctate deposition of calcium during endochondral bone formation, resulting in the characteristic finding of epiphyseal stippling on radiographs. While otolaryngologic manifestations such as nasomaxillary hypoplasia and mixed hearing loss are common, tracheobronchial calcification occurs rarely in neonates with CDP. The management of CDP-related airway stenosis is complex and there is limited literature pertaining to outcomes of airway interventions. Herein, we describe the clinical course and outcome of tracheal dilation for a newborn patient with CDP. Laryngoscope, 134:1464-1468, 2024.

RESUMO

BACKGROUND: Pediatric tracheostomy decannulation protocols vary among institutions and may include toleration of Passy Muir Valve (PMV), microlaryngoscopy and bronchoscopy (MLB) findings, and polysomnography evaluation. Transtracheal pressure (TTP) is an objective measurement utilized to evaluate PMV toleration. We aimed to investigate the role of TTP in decannulation candidates and compare TTP measurements with polysomnography and MLB findings. METHODS: A retrospective cohort study of children who underwent TTP measurement during PMV trial between December 2012 and November 2022. RESULTS: A total of 79 patients underwent TTP measurement and MLB evaluation; of these, 16 (20.3%) patients had a capped polysomnography. Twenty-eight (35.4%) patients had TTPs ≤10 cm H2O, and 51 (64.6%) patients had TTPs >10 cm H2O. The most common indication for tracheostomy was upper airway obstruction (n = 41, 51.9%), followed by a need for mechanical ventilation (n = 24, 30.4%). Twenty-five (31.6%) patients were decannulated. Patients with TTPs ≤10 cm H2O had a mean Apnea-Hypopnea Index of 0.17 ± 0.26/h compared with 6.93 ± 7.67/h in those with TTPs >10 cm H2O, p = 0.0365. Patients with TTPs >10 cm H2O were found to have a significantly higher occurrence of airway obstruction (96.1% vs. 46.4%, p < 0.0001) and multilevel airway obstruction (70.6% vs. 21.4%, p < 0.0001) on MLB. Neither TTP measured at time of PMV assessment nor capped polysomnography was associated with successful decannulation. CONCLUSIONS: TTP measurements at time of PMV evaluation are associated with polysomnography and MLB findings. One-time PMV measurements were not indicative of decannulation success.

RESUMO

OBJECTIVE: Epiglottopexy has been an increasingly utilized intervention in children with epiglottic prolapse and airway obstruction. Given the role of the epiglottis in protecting the airway during swallowing and the potential effect of repositioning the epiglottis on the passage of the bolus, we aimed to compare swallowing outcomes before and after epiglottopexy in children. STUDY DESIGN: A retrospective cohort study. SETTING: Tertiary care children's hospital. METHODS: Data were extracted from charts of children who underwent epiglottopexy and had a subsequent instrumental swallowing evaluation between January 2018 and September 2022. RESULTS: A total of 93 patients underwent epiglottopexy. Of these, 38 patients met inclusion requirements. The mean age at surgery was 41 ± 47 months. Most patients (n = 37, 97.4%) had significant comorbidities such as secondary airway lesions (n = 33, 91.7%), a genetic or syndromic disorder (n = 25, 69.4%), and dysphagia (n = 29, 76.3%). All patients had a concurrent procedure at the time of epiglottopexy with supraglottoplasty (n = 24, 63.2%) and lingual tonsillectomy (n = 16, 42.1%) being the most common. No changes in initiation or patterns of swallowing were noted postoperatively. A total of 7 (18.4%) patients had worsening swallow function: 2 had new-onset dysphagia, and 5 had worsening pre-existing dysphagia. Liquid or food textures penetrated remained unchanged or improved in most cases. No risk factors for worsening dysphagia were identified in our cohort. CONCLUSION: Children with medical comorbidities undergoing epiglottopexy with additional airway interventions may experience new or worsening dysphagia. However, the procedure is generally safe without notable patterned changes in the swallowing mechanism.

RESUMO

OBJECTIVE: To provide recommendations for a comprehensive management approach for infants and children presenting with symptoms or signs of aspiration. METHODS: Three rounds of surveys were sent to authors from 23 institutions worldwide. The threshold for the critical level of agreement among respondents was set at 80 %. To develop the definition of "intractable aspiration," each author was first asked to define the condition. Second, each author was asked to complete a 5-point Likert scale to specify the level of agreement with the definition derived in the first step. RESULTS: Recommendations by the authors regarding the clinical presentation, diagnostic considerations, and medical and surgical management options for aspiration in children. CONCLUSION: Approach to pediatric aspiration is best achieved by implementing a multidisciplinary approach with a comprehensive investigation strategy and different treatment options.

RESUMO

PURPOSE: To evaluate the feasibility and efficacy of sorafenib and everolimus in renal cell carcinoma (RCC). METHODS: Patients with advanced RCC and ≤ 1 previous targeted therapy were treated. RESULTS: Maximum tolerated doses were sorafenib 200 mg PO BID, everolimus 35 mg PO once weekly. Dose-limiting toxicity was hand-foot syndrome. The response rate was 13%; median PFS was 5.45 months (95% CI: 3.8-7.6). Skin toxicity, fatigue, hypertension, proteinuria, and mucositis (usually Grade 2) were common. CONCLUSIONS: Fifty percent doses of sorafenib and everolimus were required when these drugs were combined. No increase in efficacy was suggested; toxicity was modestly increased.

RESUMO

OBJECTIVES: (1) Identify the time required for completion, submission, and acceptance of a Triological Thesis and trends for thesis acceptance. (2) Determine the current Triological Society demographics and identify variances based on separated age groups of the current membership. STUDY DESIGN: Retrospective review of The Triological Society database and survey of candidates and fellows. METHODS: Data from the records of all candidates and fellows of the Triological Society were reviewed to determine the number of years from candidate to active fellow status for all members inducted into the Triological Society from 1990 to 2018. In addition, all current candidates, active and senior fellows were surveyed online to capture demographic data and opinions regarding the Triological Society. RESULTS: Since 1990, there has been a steady increase in the number of candidates and theses accepted. Of candidates successfully completing theses, 73% did so within 3 years and 90% within 5 years. Based on the 514 of 809 (64%) active and senior fellows responding to the survey, 83% reported being male and 15% female. Also, 73% reported as Caucasian, 12% Asian, 2% Hispanic, 2% Black, 0% Native American, and 2% Mixed Race. Of the 93 of 178 (52%) active candidates (those authorized to prepare a thesis) responding to the survey, 70% reported as male, 28% female, 58% Caucasian, 17% Asian, 6% Hispanic, 5% Black, 0% Native American, and 3% Mixed Race. CONCLUSIONS: The Triological Society continues to grow, and its membership is becoming more diverse, including more women and wider ethnic diversity. Candidates should plan for submitting their thesis as early as possible as data demonstrates the greatest likelihood of success if done within 3 years.
