Abstract
BACKGROUND Effect of inter-swallow interval on the contractility of smooth muscle esophagus is well-documented. However, the effects on peristalsis of the striated esophagus have not been systematically studied. A better understanding of striated esophagus motor function in health and disease may enhance the interpretation of manometric studies and inform clinical care. The aim of this study was to assess the effect of inter-swallow interval on striated esophagus compared to findings with that of the smooth muscle esophagus. METHODS We performed two sets of studies to (1) determine the effect of various inter-swallow interval in 20 healthy volunteers and (2) assess the effect of ultra-short swallow intervals facilitated by straw drinking in 28 volunteers. We analyzed variables using ANOVA with Tukey's pairwise comparison and paired t-test. KEY RESULTS Unlike smooth muscle esophagus, the striated esophagus contractile integral did not change significantly for swallow intervals ranging from 30 to 5 s. On the contrary, striated esophagus demonstrated absent or reduced peristalsis in response to ultra-short (<2 s) intervals during straw-facilitated multiple rapid swallows. CONCLUSIONS AND INFERENCES Striated esophagus peristalsis is subject to manometrically observed inhibition during swallows with ultra-short intervals. Inter-swallow intervals as short as 5 s that inhibit smooth muscle esophagus peristalsis do not inhibit striated muscle peristalsis. The mechanisms of these observations are unknown but may relate to central or myenteric nervous system influences or the effects of pharyngeal biomechanics.

Abstract
BACKGROUND The clinical features of pediatric cyclic vomiting syndrome (CVS) often evolve over time. Many patients develop a constellation of chronic symptoms that suggest autonomic nervous system (ANS) dysfunction during adolescence. We aimed to determine the proportion of children with CVS who develop chronic rather than episodic symptoms consistent with ANS dysfunction. METHODS Retrospective chart review of children ages 0-18 years followed in an outpatient tertiary care CVS center. Patients completed standardized questionnaires at intake and follow-up visits, documenting clinical symptom pattern. Continuous variables are summarized as median [interquartile range (IQR)]. A Mann-Whitney test was used for group comparisons. RESULTS One hundred subjects were included. A total of 40% developed symptoms of ANS dysfunction (ANS+); 20% were confirmed by comprehensive ANS testing, 11% by orthostatic vital sign abnormalities, and 9% by clinical symptoms. The median (IQR) age at onset of chronic symptoms was 14 (10.02, 15) years. The presence of another disorder of gut-brain interaction ( P = 0.018) and a greater number of comorbidities ( P = 0.031) were more common in the ANS+ group. ANS+ subjects missed more school days ( P = 0.047) and were seen less frequently in the emergency department ( P = 0.023). CONCLUSIONS Many children with CVS (40%) develop symptoms consistent with clinical dysautonomia in adolescence. These patients experience more comorbid conditions and a greater impact on school attendance, possibly representing a worsened quality of life as their disease course transitions to daily symptoms. When symptoms of CVS change over time, therapeutic interventions may need to be adjusted and targeted accordingly.

Abstract
BACKGROUND Aprepitant is a neurokinin-1 receptor antagonist, and recent guidelines by the American Neurogastoenterology and Motility Society recommend its use as prophylaxis in moderate-to severe cyclic vomiting syndrome (CVS). Data are limited to small studies in children. We aimed to determine its efficacy in adults with CVS. METHODS A retrospective review of CVS patients diagnosed using Rome criteria at a tertiary referral center was conducted. Drug response was defined as >50% reduction in symptoms and/or healthcare utilization. An intent-to-treat (ITT) analysis was conducted. KEY RESULTS Of 96 patients prescribed aprepitant, 26 (27%) were unable to start due to cost/lack of insurance coverage. Of 70 receiving therapy, mean age was 33 ± 11 years; 51 (73%) were female and 56 (80%) Caucasian. The majority (93%) were refractory to other prophylactic medications. Aprepitant was taken thrice weekly in 51 (73%), daily in 16 (23%) and a few times a month in 3 (4%) due to cost. Fifty (71.4%) had a global symptom response to aprepitant. There was significant reduction in the number of CVS episodes (14.5 ± 11.7 to 6.2 ± 8.0, p < 0.0001), emergency department visits (4.2 ± 7.7 to 1.8 ± 3.4, p = 0.006), and hospital admissions (1.6 ± 3.9 to 0.8 ± 2.1, p = 0.02) in patients treated with aprepitant. Seven (10%) discontinued the drug due to minor side effects. CONCLUSIONS AND INFERENCES Aprepitant is a safe and effective prophylactic medication in adults with refractory CVS. Adequate insurance coverage is a major barrier preventing its use.

Abstract
BACKGROUND Cyclic vomiting syndrome (CVS) is a disorder of gut-brain interaction (DGBI) characterized by recurrent episodes of nausea and vomiting. Most children outgrow their CVS symptoms and develop migraine headaches, but there are limited data in adults. We thus sought to determine the natural history of CVS in adults. METHODS We conducted a retrospective analysis of patients at a specialized tertiary care clinic. Frequency of CVS episodes, emergency department (ED) visits, and hospitalizations were recorded at the index visit and at follow-up. KEY RESULTS Of 455 CVS patients with complete data, mean age was 33 ± 13 years, 294 (65%) were female, and 392 (86%) were Caucasian. Mean duration of follow-up was 47.4 ± 37.2 months. There was a significant reduction in frequency of CVS episodes/year (18 to 6.8), ED visits (6.1 to 2), and hospitalizations (2.3 to 0.7) (all p-values < 0.001) but only 88 (19%) of patients had complete resolution of episodes at follow-up. On multivariable regression analysis, non-white race [0.33 (0.11-0.98) p = 0.01], comorbidity count [0.77 (0.62-0.95) p = 0.01], cannabis use [0.36 (0.2-0.65) p = 0.0007], and aprepitant use [0.2 (0.08-0.005) p < 0.001] were associated with a reduced odds of complete resolution of CVS episodes. Of note, 19 patients (4%) died. CONCLUSIONS AND INFERENCES While most adults with CVS improved with specialized care, in contrast to children, only a small subset (~1 in 5) had complete resolution of symptoms. Reasons for the effects of race, cannabis use, and comorbidity burden on outcomes in CVS are unclear and warrant further investigation.

Abstract
Abstract
Background and purpose
Previous studies have shown that the role of global longitudinal 2DS in diagnosing and detecting coronary artery disease is modest. However, data on the sensitivity of the regional 2DS assessment is lacking (1–6). The aim of this study was to determine whether in echocardiographic evaluation of myocardial ischemia, regional 2D strain (2DS) assessment is more sensitive and specific in detecting ischemia due to critical stenosis of one or more coronary arteries in comparison with current standard of visual assessment of regional wall motion abnormalities (RWMA).
Material and methods
This retrospective study included 123 patients admitted through the Emergency Department across 36 months with the diagnosis of NSTE-ACS without previously known CAD or LBBB who underwent coronary angiography within the first 24 hours and had an echocardiogram with RWMA analysis done prior to procedure. 2DS analysis of regional longitudinal peak systolic strain (LPSS) according to the 18-segment model was performed by four clinicians, blinded to patient's clinical data.
Results
A significant correlation was found between individual parameters of LPSS and significant stenosis of all three major coronary vessels (>70% narrowing on coronary angiography, Table 1). Lower regional LPSS correlated well anatomically with the supplying arteries; for example, patients with LAD stenosis had significantly lower regional LPSS in all apical segments, lateral, anteroseptal and anterior mid segments and anterior basal segment. Similar patterns were seen in the LCx and RCA regions. Three graphs show the sensitivity and specificity of the most sensitive segments for each artery. The diagnostic accuracy of endocardial and epicardial regional LPSS was similar to the average regional LPSS.
Conclusion
We have shown that regional 2DS could be a good predictor of the presence and localization of coronary stenosis for each of the three main coronary arteries but further studies are needed to confirm this assumption.

Abstract
OBJECTIVE To develop and assess an evidence-based, individualized Cyclic Vomiting Syndrome Action Plan (CVSAP) to optimize both preventative and acute care. STUDY DESIGN This implementation science project synthesized a combination of clinical practice guidelines, published literature, and clinical experience by a team of CVS clinicians to develop the CVSAP. The tool was developed to include validated pictograms and an automatic, embedded, weight-based dosing calculator to output acute management recommendations. The final version of the CVSAP was tested by patients/caregivers, readability calculators, medical librarians, and clinicians using validated metrics. RESULTS All pictograms met the criteria for inclusion in the CVSAP. A composite readability score of 5.32 was consistent with a fifth-grade level. Patients/caregivers (n = 70) judged the CVSAP to be of high quality with consumer information rating form rating of 84.2%. Six medical librarians rated the CVSAP to have 93% understandability and 100% actionability, and 33 clinicians completing the SAM generated a suitability rating of 87.5%. CONCLUSIONS The CVSAP visually highlights individualized care plan components to facilitate optimized preventative and acute CVS care. Further investigation will determine if CVSAP increases caregiver confidence and compliance in home management and improves quality of life and clinical outcomes for patients with CVS.

Abstract
BACKGROUND Joint hypermobility (JH) is associated with autonomic nervous system dysregulation and functional abdominal pain disorders (FAPDs). Understanding the neurophysiological processes linking these conditions can inform clinical interventions. Autonomic activity regulates gastrointestinal (GI) sensorimotor function and may be a key mechanism. The aims of this study were to examine the relation of JH with dynamic autonomic activity and parasympathetic regulation in adolescents with FAPDs and identify optimal JH cutoff scores that best index autonomic regulation in FAPDs. METHODS A total of 92 adolescents with FAPDs and 27 healthy controls (age 8-18 years; 80% female) were prospectively enrolled. JH was assessed by Beighton scores. ECG recordings were conducted during supine, sitting, and standing posture challenges. ECG-derived variables-heart period (HP), respiratory sinus arrhythmia (RSA), and vagal efficiency (VE)-were analyzed using linear regression and mixed effects modeling. KEY RESULTS Beighton scores of ≥4 optimally distinguished autonomic function. Adolescents with FAPD and JH had reduced VE compared to adolescents with FAPDs without JH (B = 18.88, SE = 6.25, p = 0.003) and healthy controls (B = 17.56, SE = 8.63, p = 0.044). These subjects also had lower and less dynamic RSA and HP values during posture shifts, with strongest differences in supine position and using the VE metric. CONCLUSIONS & INFERENCES Suboptimal autonomic regulation indexed by reduced vagal efficiency may be a mechanism of symptoms in hypermobile FAPD patients with Beighton score ≥ 4. Autonomic disturbance may serve as potential intervention target for patients with JH and functional GI disorders.

Abstract
BACKGROUND There are no pediatric norms for gastric emptying (GE) measured by nuclear scintigraphy. The 13 C-labeled, stable isotope GE breath test (GEBT) is a non-radioactive alternative. We aimed to determine normative GEBT ranges in a cohort of healthy children and examine the influence of age, gender, puberty, and body surface area (BSA). METHODS Healthy children ages 8-18 years completed the [13 C]-Spirulina platensis GEBT after an overnight fast. Breath samples were collected at baseline, every 15 min × 1 h, then every 30 min for 4 h total. The 13 CO2 excretion rate was determined by the change in 13 CO2 /12 CO2 over time in each breath sample, expressed as kPCD (Percent 13 C Dose excreted/min). A mixed model with random time was used for multivariable analysis and outcome fit into a quadratic model. KEY RESULTS The 100 subjects completed the test meal within allotted time. Median (IQR) age was 13.5 (11.3-15.5) years; 51% were female. Females had lower 13 CO2 excretion rates (slower GE) than males across time (p < 0.001) while decreased excretion rates correlated with higher BSA (p = 0.015). Gender differences were also noted within pubertal stages with females showing slower GE. Multivariable analysis suggested that pre-pubertal children have faster GE than both peri- and post-pubertal groups (p < 0.0001). CONCLUSIONS & INFERENCES Gender, puberty, and BSA influence GE rates in healthy children more than age. Although further data are needed, pubertal stage and hormonal influences may be unique factors to consider when assessing GE in children.

Abstract
OBJECTIVES/BACKGROUND Cyclic vomiting syndrome (CVS) is a disabling disorder of gut-brain interaction manifested by stereotypical and severe episodes of nausea and vomiting. Prevalence data indicate that CVS affects 1-2% of children and there has been a recent dramatic rise in diagnosed adults. METHODS This narrative review summarizes relevant literature pertaining to pediatric and adult CVS and provides a guide to management based on extensive clinical experience. RESULTS More timely diagnosis is facilitated by an expert consensus diagnostic approach and limited testing. Some diagnostic tests of exclusion remain essential. These include an upper gastrointestinal (GI) contrast study to exclude intestinal malrotation and basic laboratory screening. An abdominal ultrasound is recommended to exclude renal hydronephrosis in children and biliary disease in adults. Exclusion of metabolic/genetic conditions is warranted in those with specific warning signs, presentation in infants/toddler age, and in those with refractory disease. In the absence of chronic GI symptoms, referral to a GI specialist for upper endoscopy is generally not necessary in children but recommended in adults. A large subset termed migraine-equivalent CVS display strong clinical and genetic features of migraine. A unifying pathophysiologic core concept involves neuronal hyperexcitability and aberrant central modulation of autonomic signals. This is coupled with multiple susceptibility factors including mitochondrial dysfunction/cellular energy deficits, a hyper-responsive hypothalamic-pituitary-adrenal axis and many comorbidities that increase vulnerability to triggering events. CVS episodes are frequently triggered by stressors and intercurrent illnesses. Lifestyle and non-pharmacological interventions thus play a pivotal role in successful management. Pharmacological therapies are categorized into abortive, supportive/rescue, and prophylactic treatments. The majority respond particularly well to migraine-focused treatment strategies. CONCLUSION Despite improved characterization and understanding, CVS remains classified as a functional disorder of brain-gut interaction that is often disjointly managed by generalists and subspecialists. Early recognition, evaluation, and management will facilitate care and improve outcomes. Further research into its natural history with common progression to migraine headaches, neuroendocrine mechanisms, and the pathophysiologic relation to migraine diathesis is much needed.

Abstract
BACKGROUND & AIMS Auricular neurostimulation therapy, in which a noninvasive device delivers percutaneous electrical nerve field stimulation (PENFS) to the external ear, is effective in pediatric patients with functional abdominal pain disorders. Preclinical studies showed that PENFS modulates central pain pathways and attenuates visceral hyperalgesia. We evaluated the efficacy of PENFS in adolescents with irritable bowel syndrome (IBS). METHODS We analyzed data from pediatric patients with IBS who participated in a double-blind trial at a tertiary care gastroenterology clinic from June 2015 through November 2016. Patients were randomly assigned to groups that received PENFS (n = 27; median age, 15.3 y; 24 female) or a sham stimulation (n = 23; median age, 15.6 y; 21 female), 5 days/week for 4 weeks. The primary endpoint was number of patients with a reduction of 30% or more in worst abdominal pain severity after 3 weeks. Secondary endpoints were reduction in composite abdominal pain severity score, reduction in usual abdominal pain severity, and improvement in global symptom based on a symptom response scale (-7 to +7; 0 = no change) after 3 weeks. RESULTS Reductions of 30% or more in worst abdominal pain were observed in 59% of patients who received PENFS vs 26% of patients who received the sham stimulation (P = .024). The patients who received PENFS had a composite pain median score of 7.5 (interquartile range [IQR], 3.6-14.4) vs 14.4 for the sham group (IQR, 4.5-39.2) (P = .026) and a usual pain median score of 3.0 (IQR, 3.0-5.0) vs 5.0 in the sham group (IQR, 3.0-7.0) (P = .029). A symptom response scale score of 2 or more was observed in 82% of patients who received PENFS vs 26% of patients in the sham group (P ≤ .001). No significant side effects were reported. CONCLUSIONS Auricular neurostimulation reduces abdominal pain scores and improves overall wellbeing in adolescents with IBS. PENFS is a noninvasive treatment option for pediatric patients with functional bowel disorders. ClinicalTrials.gov no: NCT02367729.

Abstract
BACKGROUND Due to scarcity of scientific literature on pediatric gastroparesis, there is a need to summarize current evidence and identify areas requiring further research. The aim of this study was to provide an evidence-based review of the available literature on the prevalence, pathogenesis, clinical presentation, diagnosis, treatment, and outcomes of pediatric gastroparesis. METHODS A search of the literature was performed using the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines with the following databases: PubMed, EMBASE, Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects, Cochrane Central Register of Controlled Trials, and Web of Science. Two independent reviewers screened abstracts for eligibility. KEY RESULTS Our search yielded 1085 original publications, 135 of which met inclusion criteria. Most articles were of retrospective study design. Only 12 randomized controlled trials were identified, all of which were in infants. The prevalence of pediatric gastroparesis is unknown. Gastroparesis may be suspected based on clinical symptoms although these are often non-specific. The 4-hour nuclear scintigraphy scan remains gold standard for diagnosis despite lack of pediatric normative comparison data. Therapeutic approaches include dietary modifications, prokinetic drugs, and postpyloric enteral tube feeds. For refractory cases, intrapyloric botulinum toxin and surgical interventions such as gastric electrical stimulation may be warranted. Most interventions still lack rigorous supportive data. CONCLUSIONS Diagnosis and treatment of pediatric gastroparesis are challenging due to paucity of published evidence. Larger and more rigorous clinical trials are necessary to improve outcomes.

Abstract
Gastrointestinal (GI) motility disorders are associated with suboptimal nutrition in children, mainly because of malabsorption and symptoms limiting dietary intake. Apart from medical therapy, nutrition support has a crucial role in maintaining growth and improving clinical outcomes in children. Based on recent data and guidelines, this review provides an overview of nutrition assessment and specific interventions for common pediatric GI disorders including gastroesophageal reflux disease, esophageal motility disorders, gastroparesis, chronic intestinal pseudo-obstruction, and constipation. Several approaches including diet modification, enteral nutrition (gastric vs post-pyloric, temporary vs permanent access, bolus vs continuous), and parenteral nutrition need to be tailored based on patient's nutrition and clinical assessment.

Abstract
BACKGROUND Nausea frequently co-exists with functional abdominal pain disorders (FAPDs) and may be linked to a higher disease burden. This study aimed to prospectively compare multisystem symptoms, quality of life, and functioning in FAPDs with and without nausea. METHODS Adolescents ages 11-18 years fulfilling Rome III criteria for a FAPD were grouped by the presence or absence of chronic nausea. Subjects completed validated instruments assessing nausea (Nausea Profile Questionnaire = NPQ), quality of life (Patient-Reported Outcome Measurement Information System), functioning (Functional Disability Inventory), and anxiety (State-Trait Anxiety Inventory for Children). Group comparisons were performed for instruments, multisystem symptoms, school absences, and clinical diagnoses. KEY RESULTS A total of 112 subjects were included; 71% reported chronic nausea. Patients with Nausea compared to No Nausea had higher NPQ scores (P ≤ 0.001), worse quality of life (P = 0.004), and greater disability (P = 0.02). State and trait anxiety scores were similar (P = 0.57, P = 0.25). A higher NPQ score correlated with poorer quality of life, more disability, and higher anxiety. Specific comorbidities were more common in Nausea vs No Nausea group: dizziness (81% vs 41%; P ≤ 0.001), concentrating difficulties (68% vs 27%; P ≤ 0.001), chronic fatigue (58% vs 20%; P = 0.01), and sleep disturbances (73% vs 48%; P = 0.02). The Nausea group reported more school absences (P = 0.001) and more commonly met criteria for functional dyspepsia (P = 0.034). CONCLUSION AND INFERENCES Nausea co-existing with FAPDs is associated with a higher extra-intestinal symptom burden, worse quality of life, and impaired functioning in children. Assessing and targeting nausea therapeutically is essential to improve outcomes in FAPDs.

Abstract
PURPOSE OF REVIEW Cyclic vomiting syndrome (CVS) is a disabling functional gastrointestinal disorder characterized by severe vomiting episodes that alternate with symptom-free periods. The purpose of this review is to summarize current knowledge and highlight most recent data on prevalence, diagnosis, management, and impact of CVS in children and adults. RECENT FINDINGS Originally thought to be a pediatric disorder, the past decade has witnessed a considerable increase in CVS diagnosed in adults. Despite improved recognition of CVS, without a delineated pathophysiology and specific biomarker, it remains classified as a functional gastrointestinal disorder. Migraines and CVS share a common pathway based on several studies and response to migraine therapy. Recent work has begun to expand the list of comorbidities and identify plausible mechanisms and new therapeutic avenues. This review seeks to highlight best practices and novel therapies for CVS based on expert consensus and review of available literature.

Abstract
OBJECTIVE To determine nationwide prevalence and healthcare utilization in children with anorectal malformations and associated anomalies over a 6-year period. STUDY DESIGN We used the Kids' Inpatient Database for the years 2006, 2009, and 2012 for data collection. International Classification of Diseases, Ninth Revision codes were used to identify patients with anorectal malformations and associated anomalies. RESULTS A total of 2396 children <2 years of age with anorectal malformations were identified using weighted analysis; 54.3% of subjects were male. The ethnic subgroups were 40.1% white, 23.6% Hispanic, 9.3% African American, and 27% other ethnicity. Other congenital anomalies were reported in 80% of anorectal malformations and were closely associated with increased length of stay and costs. A genetic disorder was identified in 14.1% of the sample. Urogenital anomalies were present in 38.5%, heart anomalies in 21.2%, and 8.6% had vertebral anomalies, anal atresia, cardiac defects, tracheoesophageal fistula and/or esophageal atresia, renal anomalies, and limb defects association. Anorectal malformations with other anomalies including vertebral anomalies, anal atresia, cardiac defects, tracheoesophageal fistula and/or esophageal atresia, renal anomalies, and limb defects association incurred significant hospital charges when compared with anorectal malformations alone. The average annual healthcare expenditure for surgical correction of anorectal malformations and associated anomalies for the 3 years was US $45.5 million. CONCLUSIONS This large, major nationally representative study shows that majority of children with anorectal malformations have additional congenital anomalies that deserve prompt recognition. The high complexity and need for lifelong multidisciplinary management is associated with substantial healthcare expenditure. This information complements future healthcare resource allocation and planning for management of children with anorectal malformations.

Abstract
OBJECTIVE To determine if children with benign joint hypermobility (BJH) syndrome and chronic functional pain disorders have more autonomic dysfunction. STUDY DESIGN Retrospective chart review study of pediatric patients seen in the pediatric neurogastroenterology and autonomic clinic who underwent autonomic testing and had either a Beighton score of ≥6 and met Brighton criteria for BJH (with BJH) or a score of ≤2 (no BJH). RESULTS Twenty-one female subjects (10 without BJH) met inclusion criteria; 64% of BJH had diagnosis confirmed by genetics consultation. We evaluated for postural tachycardia syndrome, syncope, orthostatic intolerance, and orthostatic hypotension. None of these diagnoses, as well as baseline heart rate, peak heart rate in first 10 minutes of head up tilt (P = .35 and P = .61, respectively), and sudomotor index (suggestive of autonomic neuropathy) (P = .58), showed differences between the groups. Age of onset of symptoms was also similar (P = .61) (BJH vs without BJH: median [range]:15.6 years [12.9-17.5] vs 15.4 years [11.1-18.2]). There was no difference between groups in complaints of migraine, chronic nausea, chronic fatigue, lightheadedness, dizziness, fainting >3 times/lifetime, delayed onset of sleep, irritable bowel syndrome, dyspepsia, abdominal migraine, functional abdominal pain, constipation, or fibromyalgia. CONCLUSIONS Children with chronic functional pain disorders and BJH have autonomic testing findings and comorbid features compared with a similar cohort of subjects without BJH, suggesting that BJH is not the driver of the autonomic and comorbid disorders.

Abstract
OBJECTIVES To evaluate the prevalence of nausea and its association with functional gastrointestinal disorders (FGIDs) in a large-scale, population-based study of Latin American school children. STUDY DESIGN This cross-sectional study collected data from children in 3 Latin American countries. A Spanish version of the Questionnaire on Pediatric Gastrointestinal Symptoms-Rome III Version (QPGS-III) was administered to school children in Central and South America. Subjects were classified into FGIDs based on Rome criteria (QPGS-III). Students from 4 public and 4 private schools in the countries of El Salvador, Panama, and Ecuador participated in this epidemiologic study. RESULTS A total of 1137 school children with mean age 11.5 (SD 1.9, range 8-15) years completed the QPGS-III (El Salvador n = 399; Panama n = 321; Ecuador n = 417). Nausea was present in 15.9% of all school children. Two hundred sixty-eight (24%) children met criteria for at least 1 FGID. Nausea was significantly more common in children with FGIDs compared with those without: El Salvador 38% vs 15% (P < .001); Panama 22% vs 7% (P < .001); Ecuador 25% vs 13% (P = .004). Among children with FGIDs, those with functional constipation had a high prevalence of nausea. Nausea was significantly more common in girls and children attending private schools. CONCLUSIONS Nausea is commonly present in Latin American school children. FGIDs are frequently associated with nausea.

Abstract
OBJECTIVE To determine if several multisystem comorbid conditions occur more frequently in subjects with tilt-table defined postural tachycardia syndrome (POTS) compared with those without. STUDY DESIGN Retrospective chart review of 67 subjects aged 6-24 years, referred to a tertiary care neurogastroenterology and autonomic disorders clinic for a constellation of functional gastrointestinal, chronic pain, and autonomic complaints. All patients underwent formal autonomic testing, Beighton scores assessment for joint hypermobility (0-9), and fibromyalgia tender points (0-18) (43 subjects). RESULTS Twenty-five subjects (37%) met tilt table criteria for POTS. The median age of 16 years (range, 12-24 years) in the POTS group differed from 15 years (range, 6-21 years) in the no-POTS group (P = .03). Comorbidities including chronic fatigue, sleep disturbances, dizziness, syncope, migraines, functional gastrointestinal disorders, chronic nausea, fibromyalgia, and joint hypermobility did not differ between groups. All subjects with fibromyalgia by tender point-examination had a Beighton score ≥ 4 (P = .002). CONCLUSIONS Comorbid conditions are equally prevalent in children and young adults with and without tilt-table defined POTS, suggesting that POTS itself is not a cause of the other comorbidities. Instead, POTS likely reflects another comorbid condition in children with functional disorders. Dizziness and syncope, classically associated with POTS, are not predictive of a diagnosis of POTS by tilt table, a test that is still required for formal diagnosis. These results suggest a paradigm shift in the concept of POTS as the physiological basis of many functional symptoms.

Abstract
OBJECTIVE To describe the effects of childhood functional constipation compared with functional constipation plus fecal incontinence on quality of life, evaluating effects on physical, psychosocial, and family functioning. STUDY DESIGN This prospective, multicenter study collected data from 5 regional children's hospitals. Children meeting Rome III criteria for functional constipation were included. Parents completed the following 5 instruments: Pediatric Quality of Life Inventory (PedsQL), PedsQL-Family Impact Module, Functional Disability Inventory-Parent Version, Pediatric Inventory for Parents (PIP), and Pediatric Symptom Checklist-Parent Report. RESULTS Families of 410 children aged 2-18 years (mean [SD], 7.8 [3.5] years; 52% male) were included. Children with functional constipation+fecal incontinence had worse quality of life than children with functional constipation alone (PedsQL Total Score, P ≤ .03). Older children with functional constipation + fecal incontinence had lower quality of life than their younger counterparts (PedsQL Total Score, P ≤ .047). Children with functional constipation+fecal incontinence had worse family functioning (PedsQL-Family Impact Module Total Score, P ≤ .012), greater parental stress (PIP-F Total Score, P ≤ .016; PIP-D Total Score, P ≤ .013), and poorer psychosocial functioning (Pediatric Symptom Checklist Total Score, P ≤ .003). There were no statistically significant between-group differences in physical functioning based on the functional Disability Inventory. CONCLUSION Fecal incontinence significantly decreases quality of life compared with functional constipation alone in children. Older children with functional constipation+fecal incontinence may be at particular risk. Strategies for early identification and treatment of constipation along with diagnosis and treatment of related adjustment difficulties may mitigate the negative impact of this highly prevalent condition.

Abstract
Chronic nausea is an increasingly acknowledged complaint in children. It is commonly encountered in association with functional gastrointestinal (GI) disorders but can also occur in isolation. As such, there is no pediatric diagnostic classification for chronic idiopathic nausea. The pathophysiology appears complex, from foregut motor and sensory disturbances to autonomic imbalance and CNS influences. Also, there is scarcity of specific treatments that target this highly bothersome symptom. Treatment is mainly empiric or aimed at other functional complaints. Our retrospective data indicate a high prevalence of comorbid conditions in children with chronic nausea. These include migraines, autonomic disturbances, sleep problems, fatigue, and anxiety. Identifying specific features and targeting these therapeutically may be essential for improved treatment outcomes.

Abstract
OBJECTIVE To evaluate the prevalence of joint hypermobility (JH) and comorbid conditions in children and young adults referred to a tertiary care neurogastroenterology and autonomic disorders clinic for functional gastrointestinal complaints. STUDY DESIGN This was a retrospective chart review of 66 new patients aged 5-24 years who fulfilled at least 1 pediatric Rome III criteria for a functional gastrointestinal disorder (FGID) and had a recorded Beighton score (n = 45) or fibromyalgia tender point score (n = 45) based on physician examination. Comorbid symptoms were collected and autonomic testing was performed for evaluation of postural tachycardia syndrome (POTS). RESULTS The median patient age was 15 years (range, 5-24 years), 48 (73%) were females, and 56% had JH, a significantly higher rate compared with population studies of healthy adolescents (P < .001; OR, 10.03; 95% CI, 5.26-19.13). POTS was diagnosed in 34% of patients and did not correlate significantly with hypermobility. Comorbid conditions were common, including sleep disturbances (77%), chronic fatigue (93%), dizziness (94%), migraines (94%), chronic nausea (93%), and fibromyalgia (24%). CONCLUSION JH and other comorbid symptoms, including fibromyalgia, occur commonly in children and young adults with complex FGIDs. POTS is prevalent in FGIDs but is not associated with hypermobility. We recommend screening patients with complex FGIDs for JH, fibromyalgia, and comorbid symptoms such as sleep disturbances, migraines, and autonomic dysfunction.

Abstract
OBJECTIVES To compare children with primary, chronic idiopathic nausea to those with secondary nausea associated with functional abdominal pain. STUDY DESIGN Retrospective chart review of 45 children with a primary complaint of chronic nausea several times per week. Comparisons were made to prospectively collected data on 49 children with functional abdominal pain and comorbid nausea. RESULTS The majority of those affected were adolescent Caucasian females. Subjects with chronic nausea had a more severe presentation with daily 88% (vs 26%) and constant 60% (vs 10%) nausea (P < .001), one-half with peak morning intensity. In the chronic nausea group, 62% had migraines, and 71% (vs 22%) had familial migraines (P < .001), 36% had postural tachycardia syndrome and 27% cyclic vomiting syndrome. Both groups suffered comorbid symptoms (anxiety, dizziness, fatigue, and sleep problems). The chronic nausea cohort underwent extensive, negative medical evaluations. CONCLUSIONS Chronic idiopathic nausea of childhood is a poorly described symptom. Patients with primary (vs secondary) chronic nausea were more likely Caucasian, older adolescent females with severe, daily nausea and comorbid conditions such as anxiety, dizziness, and fatigue as well as significantly more migraine features. Chronic nausea is a major, disabling symptom that requires increased recognition as a separate functional entity. Future studies may need to focus on comorbid conditions including migraine and dysautonomia.

Abstract
Chronic nausea is a prevalent but poorly described symptom in adolescents. It often co-occurs with other functional gastrointestinal disorders (FGIDs) but may also present in isolation. A multitude of triggers and complex neural pathways underlie the sensation of nausea. These include gastrointestinal and blood-borne insults, dysmotility, vestibular or central nervous system pathways, an aberrant autonomic nervous system, and psychosocial factors. Although clinical algorithms are lacking, diagnosis is typically made on the basis of a thorough clinical history and without extensive testing. Treatment is mainly empiric and may be directed at comorbid symptoms such as migraine, delayed gastric emptying, orthostatic intolerance, and visceral hypersensitivity. Chronic idiopathic nausea is an increasingly prevalent symptom that needs careful clinical assessment and individualized treatment plans.

Abstract
Neuroendocrine (NE) differentiation in prostate cancer (PC) has attracted much attention since it has been shown to be associated with androgen independence and bad prognoses. In this study 34 patients with hormone refractory prostate cancer and elevated Chromogranin A (CgA) serum values were treated with estramustine for 15 months. The results were evaluated by analyzing clinical data and the serially measured total PSA and Chromogranin A serotest concentration, as well as bone scan recordings. In responders to therapy a sharp decline in CgA level was recorded as well as a slight decrease in the number of metastatic lesions in the bone. However, in 6- and 12-month nonresponders, supranormal serum CgA concentrations were measured (mean 305 +/- 122 ng/ml/ and 284 +/- 101 ng/ml, respectively). Statistical significance was found between neither of these groups (p > 0.05). Mean bone lesions data were practically identical in nonresponding groups (9.6 and 9.5) but were much lower in the respective responders (4.9 and 4.1). Twelve patients were found to be nonresponders 3 months after therapy initiation (12 out of 34, 35.3%). From the remaining 22 studied subjects a positive response patients continued in 17 patients during the next 3 months or overall in a six-month period (17 out of 34, 50%, or 17 out of 22, 77.3% from 3-month responders). After 9 months of therapy, 15 responding, patients were found (15 out of 34, 44.1%, or 15 out of 17, 88.2% from 6-month responders) while, after a full year of estramustine administration, 8 patients responded to therapy (8 out of 34, 23.5%, or 8 out of 15, 53.3% from responders after 9 months of treatment). Finally, after 15 months of treatment, only 3 responding patients found (3 out of 34, 8.8% or 3 out of 8, 37.5% from responders after 12 months of treatment). Mean response periods after 12 and 15 months of estramustine treatment were 5.5 and 5.7 months, respectively. In conclusion, the reported results indicate a 12-15 month responding period for estramustine therapy in patients with a slight initial elevation in CgA serotest (up to 150 ng/ml) and less than 10 metastatic osseous lesions. Thus, serum CgA assessment has definitely found a role in monitoring PC patients with NE positive stage D3 disease. This specially holds true as the population of aged men is rapidly increasing, posing a great challenge to urologists and oncologists in treating difficult-to-manage hormone-independent prostatic carcinoma.

Abstract
Circulating Chromogranin A (CgA), total PSA (TPSA) and F-PSA concentrations were measured in 211 patients (pt) with newly diagnosed prostate cancer (PC) and in 25 controls with benign prostatic hypertrophy (BPH). TPSA values ranging 3.5-5.5 ng/ml were found in 14 PC pt (6.6%), 5.5-9.9 ng/ml in 29 pt (13.7%), 10-19.9 ng/ml in 75 pt (35.6%), 20-50 ng/ml in 64 pt (30.3%) and > 50 ng/ml in 29 pt (13.7%). In those groups of PC pt false negative % F-PSA level > 18 was respectively measured in 0 out of 14, 2 out of 29 (6.9%) 6 out of 75 (8.0%), 61 out of 4 (9.4%) and 6 out of 29 (20.7%) pt, or totally in 20 out of 211 (9.5%) pt. Among 20 PC pt with false negative %F-PSA data elevated CgA level (> 80 ng/ml) was found in 18 subjects (18 out of 20 90%) or respectively in 0, 1/2 (50%), 516 (83%), 6 out of 6 (100%) and 6 out of 6 (100%) patients. Bone scintigraphy was performed in all pt with TPSA concentration > 10 ng/ml at the time of diagnosis. Bone lesions were respectively found in 4 out of 75 (5.3%) pt with TPSA 10-20 ng/ml, 12 out of 64 (14%) pt with TPSA level from 20-50 mg/ml and in 25k9 (75.9%) pt with. TPSA above 50 ng/ml. Overall osseous metastases were recorded in 41 out of 211 pt (19.4%) with newly diagnosed PC and in 18 of these Stage D2 pt (43.9%) elevated CgA concentration were measured Among them elevated CgA level and tumor dissemination matched with false negative %F-PSA parameter (> 18%) in 4 out of 18 (22.2%) pt as well as in 37 out of 191 (19.4%) pt with %F-PSA < 18% (p > > 0.05). In parallel, a positive CgA level in newly presented PC pt was closely associated with %F-PSA false negativity (18 out of 20, 90%). A negative correlation between TPSA elevation and the magnitude of CgA serotest level indicate differences in their biological origin and activities. According to the data reported herein we advocate the assessment of serum Chromogranin A concentration in first presented patients with clinically proven PC, elevated T-PSA level and %F-PSA parameter > 18%. Neuroendocrine structures are resistant toward hormonal treatment and hence CgA measurement is strongly suggested in all candidates for a systemic hormone therapy.
