RESUMO
INTRODUCTION: There are limited data characterizing eating habits among pediatric patients with eosinophilic esophagitis (EoE). We compared eating behaviors in pediatric patients with EoE with healthy controls and assessed the degree of correlation with symptomatology, endoscopic and histologic findings, and esophageal distensibility. METHODS: We conducted a prospective, observational study where subjects consumed 4 food textures (puree, soft solid, chewable, and hard solid) and were scored for eating behaviors including number of chews per bite, sips of fluid per food, and consumption time. Symptomatic, endoscopic, histologic, and esophageal distensibility data were collected for case subjects. RESULTS: Twenty-seven case subjects and 25 healthy controls were enrolled in our study (mean age 11.0 years, 63.5% male). Compared with healthy controls, pediatric patients with EoE demonstrated more chews per bite with soft solid (13.6 vs 9.1, P = 0.031), chewable (14.7 vs 10.7, P = 0.047), and hard solid foods (19.0 vs 12.8, P = 0.037). Patients with EoE also demonstrated increased consumption time with soft solid (94.7 vs 58.3 seconds, P = 0.002), chewable (90.0 vs 65.1 seconds, P = 0.005), and hard solid foods (114.1 vs 76.4 seconds, P = 0.034) when compared with healthy controls. Subgroup analysis based on disease status showed no statistically significant differences in eating behaviors between active and inactive EoE. Total endoscopic reference score positively correlated with consumption time ( r = 0.53, P = 0.008) and number of chews ( r = 0.45, P = 0.027) for chewable foods and with number of chews ( r = 0.44, P = 0.043) for hard solid foods. Increased consumption time correlated with increased eosinophil count ( r = 0.42, P = 0.050) and decreased esophageal distensibility ( r = -0.82, P < 0.0001). DISCUSSION: Altered eating behaviors including increased chewing and increased consumption time can be seen in pediatric patients with EoE, can persist despite histologic remission, and may be driven by changes in esophageal distensibility.

OBJECTIVE: Approximately 30% of patients with a history of repaired cleft palate (CP) go on to suffer from velopharyngeal dysfunction (VPD). This study discusses the operative management of VPD and postoperative speech outcomes in a cohort of CP patients. SETTING: An academic tertiary pediatric care center. METHODS: Retrospective cohort study. PATIENTS: Patients with history of repaired CP (Veau I-IV) who underwent operative management of VPD between January 1st, 2010 and December 31st, 2020. Operative modalities were posterior pharyngeal flap (PPF), sphincter pharyngoplasty (SPP), Furlow palate re-repair, and buccal myomucosal flap palate lengthening (PL). OUTCOME MEASURES: The primary outcome measure is postoperative speech improvement evaluated by the Pittsburgh Weighted Speech Scale (PWSS). RESULTS: 97 patients met inclusion criteria. 38 patients with previous straight-line primary palatoplasty underwent Furlow re-repair; these patients were significantly younger (7.62 vs 11.14, P < .001) and were more likely to have severe VPD per PWSS (OR 4.28, P < .01, 95% CI 1.46-12.56) when compared to VPD patients with previous Furlow repair. 21.1% of these patients required an additional non-revisional VPD procedure. The remaining patients underwent a non-revision procedure (26 PPF, 22 SPP, 11 PL); all experienced significant (P < .001 on paired t-test) reductions in PWSS total and subgroup VPD severity scores without difference in improvement between operation types. SPP was statistically associated with all-cause complication (OR 2.79, 95% CI 1.03-7.59, P < .05) and hyponasality (OR 3.27, 95% CI 1.112-9.630, P < .05). CONCLUSION: Furlow re-repair reduced need for additional VPD operations. Speech outcomes between non-revisional operations are comparable, but increased complications were seen in SPP.
RESUMO
OBJECTIVE: To determine the impact of illustrated postoperative instructions on patient-caregiver knowledge and retention. DESIGN: Prospective study with all participants receiving an educational intervention. SETTING: Pediatric plastic surgical missions in Guatemala City, Guatemala, between 2019 and 2020. PARTICIPANTS: A total of 63 majority-indigenous Guatemalan caregivers of patients receiving cleft lip and/or palate surgery. INTERVENTION: Illustrated culturally appropriate postoperative care instructions were iteratively developed and given to caregivers who were surveyed on illustration-based and text-based information at preoperative, postoperative, and four-week follow-up time points. MAIN OUTCOME MEASURE: Postoperative care knowledge of illustration-based versus text-based information as determined by the ability to answer 11 illustration- and 8 text-based all-or-nothing questions, as well as retention of knowledge as determined by the same survey given at four weeks follow-up. RESULTS: Scores for illustration-based and text-based information both significantly increased after caregivers received the postoperative instructions (+13.30 ± 3.78 % SE, + 11.26 ± 4.81 % SE; P < .05). At follow-up, scores were unchanged for illustration-based (-3.42 ± 4.49 % SE, P > .05), but significantly lower for text-based information (-28.46 ± 6.09 % SE, P < .01). Retention of text-based information at follow-up correlated positively with education level and Spanish literacy, but not for illustration-based. CONCLUSIONS: In the setting of language and cultural barriers on a surgical mission, understanding of illustration-based and text-based information both increased after verbal explanation of illustrated postoperative instructions. Illustration-based information was more likely to be retained by patient caregivers after four weeks than text-based information, the latter of which correlated with increased education and literacy.

BACKGROUND: This study updates our institutional experience with modified Furlow palatoplasty, evaluating speech outcomes and incidence of secondary speech surgery throughout development and at skeletal maturity. METHODS: Nonsyndromic patients undergoing primary modified Furlow palatoplasty between 1985 and 2005 with post-operative speech evaluations were retrospectively reviewed. Secondary speech surgery and Pittsburgh Weighted Speech Scale (PWSS) scores prior to secondary speech or orthognathic surgeries were assessed in the 5-7, 8-11, 12-14, and 15+ age groups and analyzed by Veau cleft type. RESULTS: Five hundred fifty-one patients with 895 total speech assessments were analyzed. Of 364 patients followed to age 15 or older, 19.8% underwent secondary speech surgery. Speech assessment of patients aged 15 or older without prior secondary speech surgery showed competent velopharyngeal mechanisms in 77% of patients. PWSS nasal emission scores were worse in the 5-7 age range (p=0.02), while resonance scores remained stable throughout development (p=0.2). Patients with Veau type I or II clefts had worse overall PWSS classifications in the age 5-7 and 8-11 age groups (p=0.01, p=0.03), with greater odds of secondary speech surgery relative to those with Veau type III (OR 2.9, p<0.001) or IV clefts (OR 3.6, p=0.001). CONCLUSIONS: Most patients undergoing primary modified Furlow palatoplasty do not require secondary speech surgery and achieve socially acceptable speech at skeletal maturity. However, Veau type I and II clefts are associated with increased risk for early velopharyngeal dysfunction and secondary speech surgery. Incidence of secondary speech surgery was 19.8%, an increase from our previously reported rate of 8%.
RESUMO
The size of many intertidal animals varies with tidal height. These size gradients could be produced by growth or survival varying with tidal height, or by animals moving to a preferred tidal level. The body size of the snail, Littorina sitkana, increases steadily with tidal height in rocky high intertidal habitats of British Columbia. To determine how size gradients were maintained in L. sitkana, I quantified how growth, survival, and snail movement varied with tidal height. I studied populations of L. sitkana found on sheltered pebble beach and exposed basaltic shelf habitats. Mark-recapture studies and experimental transplants showed that growth could not have produced the size gradients because snail growth rates in both habitats were as fast or faster at low tidal levels (where the snails were the smallest) than at high tidal levels. However, survival rates were lowest at low tidal levels. On pebble beaches, this was due to size selective predation on large snails by the pile perch, Rhacochilus vacca. On basaltic shelves, heavy wave action at low tidal levels may have caused the poor survival rates. Transplanted snails moved homeward on pebble beaches, but not on basaltic shelves. Reduced survival rates at low tidal levels cause size gradients in both habitats, and snail movement helps to maintain size gradients on pebble beaches.
