Abstract
PURPOSE To perform a scoping review of the evidence for therapeutic interventions to manage functional impairments associated with Rett syndrome (RTT) throughout the lifespan. METHODS MEDLINE, EMBASE, PsycINFO, CENTRAL, CINAHL, Scopus and Index to Chiropractic Literature were searched systematically up to December 2019. Two investigators independently reviewed all search results and extracted those that met the inclusion criteria. Human and animal model studies pertaining to therapies that increase functional ability or treat RTT-associated symptoms in all age groups were included. Relevant studies were grouped into intervention categories and rated using the Oxford Centre of Evidence Based Medicine Levels of Evidence. Demographics of participants, interventions, and outcomes were summarized. RESULTS Ninety-one articles representing 88 studies met the inclusion criteria, of which 80 were human clinical studies and eight were studies using animal models. Study designs were primarily case series and only six studies involved participants above the age of 40. CONCLUSION A small number of rigorously studied rehabilitation interventions have been published. Published studies aim to address a wide variety of functional impairments. Research regarding implementation of therapies for older patients with RTT is lacking and requires further exploration.

The course of awake breathing disturbances across the lifespan in Rett syndrome. Brain Dev 2018; 40:515-529. [PMID: 29657083 PMCID: PMC6026556 DOI: 10.1016/j.braindev.2018.03.010] [Citation(s) in RCA: 49] [Impact Index Per Article: 8.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/12/2017] [Revised: 02/15/2018] [Accepted: 03/27/2018] [Indexed: 11/16/2022]
Abstract
Rett syndrome (RTT), an X-linked dominant neurodevelopmental disorder caused by mutations in MECP2, is associated with a peculiar breathing disturbance exclusively during wakefulness that is distressing, and can even prompt emergency resuscitation. Through the RTT Natural History Study, we characterized cross sectional and longitudinal characteristics of awake breathing abnormalities in RTT and identified associated clinical features. Participants were recruited from 2006 to 2015, and cumulative lifetime prevalence of breathing dysfunction was determined using the Kaplan-Meier estimator. Risk factors were assessed using logistic regression. Of 1205 participants, 1185 had sufficient data for analysis, including 922 females with classic RTT, 778 of whom were followed longitudinally for up to 9.0 years, for a total of 3944 person-years. Participants with classic or atypical severe RTT were more likely to have breathing dysfunction (nearly 100% over the lifespan) compared to those with atypical mild RTT (60-70%). Remission was common, lasting 1 year on average, with 15% ending the study in terminal remission. Factors associated with higher odds of severe breathing dysfunction included poor gross and fine motor function, frequency of stereotypical hand movements, seizure frequency, prolonged corrected QT interval on EKG, and two quality of life metrics: caregiver concern about physical health and contracting illness. Factors associated with lower prevalence of severe breathing dysfunction included higher body mass index and head circumference Z-scores, advanced age, and severe scoliosis or contractures. Awake breathing dysfunction is common in RTT, more so than seizures, and is associated with function, quality of life and risk for cardiac dysrhythmia.

Abstract
OBJECTIVES Through evidence review and the consensus of an expert panel, we developed recommendations for the clinical management of gastroesophageal reflux disease, constipation, and abdominal bloating in Rett syndrome. METHODS Based on review of the literature and family concerns expressed on RettNet, initial draft recommendations were created. Wherein the literature was lacking, 25 open-ended questions were included. Input from an international, multidisciplinary panel of clinicians was sought using a 2-stage modified Delphi process to reach consensus agreement. Items related to the clinical assessment and management of gastroesophageal reflux disease, constipation, and abdominal bloating. RESULTS Consensus was achieved on 78 of 85 statements. A comprehensive approach to the assessment of gastroesophageal reflux and reflux disease, constipation, and abdominal bloating was recommended, taking into account impairment of communication skills in Rett syndrome. A stepwise approach to the management was identified with initial use of conservative strategies, escalating to pharmacological measures and surgery, if necessary. CONCLUSIONS Gastrointestinal dysmotility occurs commonly in Rett syndrome. These evidence- and consensus-based recommendations have the potential to improve care of dysmotility issues in a rare condition and stimulate research to improve the present limited evidence base.

Abstract
OBJECTIVE We conducted a nationwide survey to determine the prevalence of common gastrointestinal and nutritional disorders in Rett syndrome (RTT) based on parental reporting and related the occurrence of these problems to age and methyl-CpG-binding protein 2 (MECP2) gene status. METHODS We designed a questionnaire that probed symptoms, diagnoses, diagnostic tests, and treatment interventions related to gastrointestinal and nutritional problems in RTT. The International Rett Syndrome Foundation distributed the questionnaire to 1666 family-based members and forwarded their responses for our review. We interrogated the Rare Disease Clinical Research Network database to supplement findings related to medications used to treat gastrointestinal problems in RTT. RESULTS Parents of 983 female patients with RTT (59%) responded and identified symptoms and diagnoses associated with gastrointestinal dysmotility (92%), chewing and swallowing difficulties (81%), weight deficits or excess (47%), growth deficits (45%), low bone mineral content or fractures (37%), and biliary tract disorders (3%). Height-for-age, weight-for-age, and body mass index z scores decreased significantly with age; height- and weight-, but not body mass index-for-age z scores were significantly lower in female subjects with MECP2 mutations than in those without. Vomiting, nighttime awakening, gastroesophageal reflux, chewing difficulty, and choking with feeding were significantly less likely to occur with increasing age. Short stature, low bone mineral content, fractures, and gastrostomy placement were significantly more likely to occur with increasing age. Chewing difficulty, choking with feeding, and nighttime awakening were significantly less likely to occur, whereas short stature was significantly more likely to occur, in female subjects with MECP2 mutations than in those without. Diagnostic evaluations and therapeutic interventions were used less frequently than the occurrence of symptoms or diagnoses in the RTT cohort. CONCLUSIONS Gastrointestinal and nutritional problems perceived by parents are prevalent throughout life in girls and women with RTT and may pose a substantial medical burden for their caregivers. Physician awareness of these features of RTT may improve the health and quality of life of individuals affected with this disorder.

Abstract
OBJECTIVE To determine the strength of the relationship between paradoxical breathing (PB) and spontaneous pleural diseases in dyspneic dogs and cats. DESIGN Cross-sectional study. ANIMALS Dogs (n = 195) and cats (194) with a recorded diagnosis of dyspnea examined at the National Veterinary Schools of Alfort and Toulouse (France) between January 2001 and October 2009. PROCEDURES Dogs and cats were divided into 2 groups according to the presence or absence of PB. Stratified analysis by species was performed. Signalment of affected animals and occurrence of PB were recorded. The relationship between PB and pleural diseases among dyspneic dogs and cats was analyzed. RESULTS A strong relationship between PB and pleural diseases was highlighted in multivariate analysis (dogs, OR = 12.6 and 95% confidence interval = 4.6 to 31.2; cats, OR = 14.1 and 95% confidence interval = 6.0 to 33.5). Paradoxical breathing prevalence among dyspneic dogs and cats was 27% and 64%, respectively. Occurrence of pleural diseases in dyspneic animals with and without PB was 49% and 9% in dogs and 66% and 13% in cats, respectively. The sensitivity and specificity of PB as a predictor of pleural diseases were 0.67 and 0.83 in dyspneic dogs and 0.90 and 0.58 in dyspneic cats, respectively. The positive and negative predictive values of PB were 0.49 and 0.91 in dyspneic dogs and 0.66 and 0.87 in dyspneic cats, respectively. Age, sex, feline breeds, and canine morphotypes in patients with PB were not significantly different from those of other dyspneic animals. CONCLUSIONS AND CLINICAL RELEVANCE PB was strongly associated with pleural diseases in dyspneic dogs and cats. The presence of this clinical sign should prompt small animal practitioners to implement appropriate emergency procedures and guide their diagnostic strategy.

Abstract
INTRODUCTION Rett syndrome is a neurologically disorder that affects approximately one in 10,000 females. CASE REPORT A 21-year-old girl with Rett syndrome was hospitalized for abdominal distention and pain. Physical examination revealed abdominal tenderness. Radiology investigation revealed bilateral free air in subdiaphragmatic area. Gastric perforation observed at laparotomy. Primary suturing and omentoplasty were performed. In the follow-up, the symptoms of intestinal obstruction occurred. Conservative treatment failed and second intervention was performed. At laparotomy severe gastric and intestinal dilatation and bowel adhesions were detected. Adhesiolysis, tube gastrostomy, and feeding jejunostomy performed. DISCUSSION Rett syndrome and associated gastric complications are uncommon. These pathologic disorders may cause gastric, intestinal necrosis, intestinal obstructions. Because of the late occurring of physical findings and insidious presentation of the gastrointestinal perforations in Rett syndrome, physicians should keep in mind this rare entity to reduce morbidity and mortality.

Abstract
Rett Syndrome is associated with decreased peristaltic esophageal waves and gastric dysmotility, resulting in swallowing difficulties and gastric dilation. Rarely, gastric necrosis and perforation occur. Our case represents the third reported case of gastric necrosis and perforation associated with Rett Syndrome. A 31-year-old female after 11 hours of intermittent emesis and constant, sharp abdominal pain presented with evidence of multiorgan system failure including hypovolemic shock, metabolic acidosis, coagulopathy, and hepatorenal failure. A chest radiograph revealed intra-abdominal free air necessitating emergent laparotomy. During exploration, a severely dilated, thin-walled stomach with an area of necrosis and gross perforation was noted. Wedge resection of the necrotic tissue and primary closure were performed. Despite aggressive perioperative resuscitation and ventilation support, the patient died 3 hours postoperatively secondary to refractory shock and hypoxemia. Severe gastric dilation can occur with Rett Syndrome and may cause gastric necrosis and perforation. Prolonged elevated gastric pressures can decrease perfusion and may contribute to perforation. Timely decompression via percutaneous endoscopic or surgical gastrostomy could decrease the risk of perforation particularly when significant gastric distention is present. Consideration of gastric necrosis and perforation in patients with Rett Syndrome may lead to earlier intervention and decreased mortality.

Abstract
This is the unusual case of a 17-year-old girl affected by Rett Syndrome (RS) who suffered acute abdominal distension and constipation for a week. Laparotomy showed massive gastric dilatation, with total necrosis and perforation. Total gastrectomy and Y-Roux esophagojejunostomy were performed. We believe the clinical status was caused by the mechanism of air swallowing, present in our patient and typical in RS. In fact, as reported, massive air bloat may result in a decrease of the intramural blood flow with consequential ischemia of the gastric wall. We stress the importance of early detection of the gastroenterological symptoms in these patients, with timely positioning of nasogastric tube and gastrostomy, to prevent serious complications potentially life-threatening as massive gastric necrosis.
