Abstract
OBJECTIVES/HYPOTHESIS To report on the prevalence of premature (PM) birth in a consecutive series of children treated for snoring and sleep-disordered breathing (S/SDB), the parameters specific to their management and variables predictive of disease severity. STUDY DESIGN A retrospective study was undertaken at a tertiary pediatric hospital. METHODS Children with history of PM and presenting with S/SDB were identified from a prospectively kept surgical database. We set out to determine the prevalence of PM among the patients presenting with S/SDB who required airway evaluations and surgery. Pulse oximetry is overnight recordable oxygen saturation and heart rate tracing that provides information about hypoxemia during sleep. This was performed on all children preoperatively. The pulse oximetry findings were used to plan for perioperative monitoring and care. A multivariable analysis was used to identify factors predictive of abnormal pulse oximetry studies. We evaluated the associated diagnoses, surgical procedures required, and response to treatment in these selected children. RESULTS Fifty-seven out of 1,038 patients were PM (33 males; mean age, 62.09 ± 34.91 months; range, 4-190 months). The mean gestational age was 30.3 ± 4.0 weeks. The prevalence rate of PM among patients treated surgically for SDB is 5.5% (95% CI 5.2-5.8) at our center. Comorbid pulmonary and gastrointestinal disorders were encountered on 23 (40%) and 17 (29.8%) occasions, respectively, and were the most commonly encountered comorbid diagnostic categories. Large airway abnormalities were encountered in 11 (19.3%) children, and the most common were subglottic stenosis (four) and laryngeal paralysis (four). Comorbid respiratory disease was negatively predictive of abnormal pulse oximetry (coefficient -0.35, P<.05). Postoperative respiratory outcomes correlated with abnormal pulse oximetry (coefficient 0.3; P<.05). CONCLUSIONS Our findings suggest children with PM presenting to pediatric otolaryngology require a comprehensive evaluation for S/SDB. A significant proportion of children with S/SDB and a history of PM frequently had pulmonary and gastrointestinal comorbidities in our cohort. One-half required admission postoperatively, and these were predictable based on preoperative pulse oximetry. Respiratory comorbidity was negatively predictive of severity of SDB. Inversely, children with untreated pulmonary comorbidities are more likely to have postoperative complications.

Risk of oesophageal adenocarcinoma among individuals born preterm or small for gestational age. Eur J Cancer 2013; 49:2207-13. [PMID: 23490653 DOI: 10.1016/j.ejca.2013.02.014] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2013] [Revised: 02/06/2013] [Accepted: 02/09/2013] [Indexed: 12/24/2022]
Abstract
BACKGROUND Gastroesophageal reflux is a main risk factor for oesophageal adenocarcinoma (EAC). Infants born preterm or small for gestational age (SGA) regurgitate more than infants born at term, and some data support the hypothesis of an association with oesophagitis, Barrett's oesophagus and EAC. This study aimed to assess the association between risk of EAC and preterm or SGA birth. METHODS In this population-based case-control study, all incident cases of EAC in Sweden between 1st January 1998 and 31st December 2004 with retrievable birth records were eligible as cases. We sampled three matched controls per case from the birth ledger at the same delivery ward as the respective case. Data on gestational age, birth weight and other perinatal exposures were extracted from the original birth records. For comparison, we collected perinatal data for cases of cardia adenocarcinoma and oesophageal squamous cell carcinoma and controls. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated. RESULTS The risk of EAC increased by 13% per week of shorter duration of gestation (OR 1.1, 95%CI 1.0-1.3), while SGA did not influence the risk. No effect of preterm birth or SGA was found on the risk of cardia adenocarcinoma or oesophageal squamous cell carcinoma. CONCLUSION Preterm birth, but not SGA, might lead to an increased risk of EAC as an adult.

Abstract
BACKGROUND & AIMS The association between gastroesophageal reflux and esophageal adenocarcinoma is likely to be mediated by inflammation. Reflux is common in infancy; the esophageal mucosa of infants born preterm or small for gestational age (SGA) could be particularly vulnerable. We investigated the association between preterm or SGA birth and risk of esophagitis early in life. METHODS We analyzed data from the Swedish birth register and the Swedish patient register to identify birth characteristics of individuals with endoscopically verified esophagitis from 1973 to 2007 and to determine their outcomes (7358 cases). Five controls were selected randomly and matched with each case (N = 38,479). Multivariable conditional logistic regression models were used to provide odds ratios (ORs) and 95% confidence intervals (CIs), adjusted for potential confounding. RESULTS The risk of esophagitis was increased among individuals born preterm (≤32 gestational weeks) (OR, 2.74; 95% CI, 2.15-3.49) or SGA (OR, 1.49; 95% CI, 1.32-1.68). When data were stratified by age at diagnosis and by sex, different risk patterns appeared. Among individuals diagnosed with esophagitis 9 years of age and younger, the OR for prematurity was 6.82 (95% CI, 4.65-10.03) and the OR for SGA at birth was 1.98 (95% CI, 1.55-2.52). Furthermore, the association with preterm birth was stronger among males (OR, 9.88; 95%, CI 5.93-16.45) than females (OR, 3.41; 95% CI, 1.81-6.41), whereas the association with SGA was stronger among females (OR, 2.50; 95% CI, 1.76-3.55) than males (OR, 1.64; 95% CI, 1.16-2.30). The risk of being diagnosed with esophagitis at age 20 or younger was not associated with preterm birth (OR, 1.02; 95% CI, 0.64-1.63), but was associated with being SGA at birth (OR, 1.31; 95% CI, 1.11-1.54). CONCLUSIONS Preterm birth is associated with esophagitis only during childhood, whereas SGA birth is associated with esophagitis during adolescence as well. The associations appear to differ between sexes.

Chronic aspiration shifts the immune response from adaptive immunity to innate immunity in a murine model of asthma. Inflamm Res 2012; 61:863-73.

Abstract
OBJECTIVE AND DESIGN The hypothesis that aspiration of gastric fluid drives the anti-ovalbumin response toward a Th2 reaction even in animals not prone to Th2 responses was evaluated. SUBJECTS Forty-eight male C57BL/6 mice were used. METHODS Mice were sensitized and challenged with ovalbumin starting 5 weeks prior to the initiation of weekly aspirations of either gastric fluid or normal saline as a control. Weekly aspiration continued during the course of exposure to ovalbumin. TREATMENT Aspiration consisted of 50 μl of gastric fluid with 50 μl of 0.9 % normal saline used as a control. Antigen exposure consisted of sensitization to ovalbumin via intraperitoneal injection on days 0 and 14 and challenge on day 21 with aerosolized antigen for 30 min. RESULTS No evidence of a shift toward a Th2 response as a result of gastric fluid aspiration was seen in the Th1-prone strain utilized, although a profound down-regulation of a broad array of T cell-associated cytokines and chemokines and up-regulation of macrophage-associated markers was observed as a result of aspiration. CONCLUSIONS These data provide support for the hypothesis that the clinical association between asthma and gastroesophageal reflux disease (GERD) does not involve an exacerbation of asthma by GERD-associated aspiration of gastric fluid, but may cause immune reactions unrelated to the asthma pathology.

Abstract
PURPOSE Preterm birth is associated with gastric acid-related disorders in infancy, but no investigators have examined this association beyond early childhood. We used antisecretory medication data to explore whether preterm birth is associated with gastric acid-related disorders in young adulthood. METHODS We conducted a national cohort study of 626,811 individuals born in Sweden in 1973 to 1979, followed up for antisecretory (proton pump inhibitor and H2-receptor antagonist) medication prescriptions from all outpatient and inpatient pharmacies nationwide from 2005 to 2009 (ages 25.5-37.0 years). We excluded individuals with congenital anomalies, and examined potential confounding by other comorbidities identified on the basis of oral anti-inflammatory or corticosteroid medication prescription. RESULTS Gestational age at birth was inversely associated with antisecretory medication prescription in young adulthood. Adjusted odds ratios for ≥1 antisecretory medication prescription/year were 3.38 (95% confidence interval [95% CI], 1.73-6.62) for individuals born at 22-27 weeks, 1.38 (95% CI, 1.19-1.60) for those born at 28-34 weeks, and 1.19 (95% CI, 1.06-1.32) for those born at 35-36 weeks, relative to those born full-term (37-42 weeks). Exclusion of individuals who were prescribed oral anti-inflammatory or corticosteroid medications (≥1/year) had little effect on these results. CONCLUSIONS These findings suggest that low gestational age at birth may be independently associated with an increased risk of gastric acid-related disorders in young adulthood.

Abstract
OBJECTIVE To evaluate the association of late-preterm birth with asthma severity among young children. METHODS A retrospective cohort study was performed with electronic health record data from 31 practices affiliated with an academic medical center. Participants included children born in 2007 at 34 to 42 weeks of gestation and monitored from birth to 18 months. We used multivariate logistic or Poisson models to assess the impact of late-preterm (34-36 weeks) and low-normal (37-38 weeks) compared with term (39-42 weeks) gestation on diagnoses of asthma and persistent asthma, inhaled corticosteroid use, and numbers of acute respiratory visits. RESULTS Our population included 7925 infants (7% late-preterm and 21% low-normal gestation). Overall, 8.3% had been diagnosed with asthma by 18 months. Compared with term gestation, late-preterm gestation was associated with significant increases in persistent asthma diagnoses (adjusted odds ratio [aOR]: 1.68), inhaled corticosteroid use (aOR: 1.66), and numbers of acute respiratory visits (incidence rate ratio: 1.44). Low-normal gestation was associated with increases in asthma diagnoses (aOR: 1.34) and inhaled corticosteroid use (aOR: 1.39). CONCLUSION Birth at late-preterm and low-normal gestational ages might be an important risk factor for the development of asthma and for increased health service use in early childhood.

Abstract
The rate of preterm birth is increasing in developed countries. Improvements in neonatal intensive care have decreased the rate of infant mortality after preterm birth, particularly for those born at the earliest gestational ages. However, the result is an increasing absolute number of preterm birth survivors who suffer from disabilities such as neurosensory, respiratory and cognitive impairments. Evidence is also accumulating demonstrating that these survivors may be at increased risk for mortality, even into later childhood, and that they may face challenges transitioning into adulthood, such as a decreased likelihood of reproduction.
