THE NERVOUS SYSTEM AND GASTROINTESTINAL FUNCTION M.A. Altaf and M.R. Sood DEV DISABIL RES REV, 2008 GASTROINTESTINAL DISORDERS IN CHILDREN WITH NEURODEVELOPMENTAL DISABILITIES P.B. Sullivan DEV DISABIL RES REV, 2008 ORAL- MOTOR IMPAIRMENT Symptoms from oral-motor impairment include feeding problems, drooling and gagging as well as dysarthria. Uncoordinated swallowing increases the rysk of pulmonary aspiration, which may or may not heralded by recurrent coughing and choking with feeds. P.B. Sullivan, 2008 ORAL- MOTOR IMPAIRMENT Feeding problems can easily lead to malnutrition in children with CP and seriously adversely effect the quality of life of theirs mothers. Those children with the severest general motor deficit are also those with the most severe degree of oral-motor impairment. This is because development of oral-motor skills mirrors general neurological maturation. P.B. Sullivan, 2008 ORAL- MOTOR IMPAIRMENT This development requires the coordination of the movement of a total of 31 pairs of striated muscles in the mouth, pharyng and oesophagus by six cranial nerves, the brain stem and the cerebral cortex. When the central control of this mass of musculature is severly impaired there is little chance of getting sufficient quantities of food and drink safely into the esophagus P.B. Sullivan, 2008 GER The high incidence of GER (15-75%) in neurologically impaired children is well recognized. Several reasons have been proposed to account for this high incidence…including hiatus hernia, adoption of a prolonged supine position, and increased intrabdominal pressure secondary to spasticity, scoliosis or seizures P.B. Sullivan, 2008 GER Nevertheless, CNS dysfunction is likely to be the prime cause of GER. As a result of neuromuscolar incoordination, the antireflux function of LES mechanism and esophageal motility are significantly impaired. Thus, food and acid and pepsin reflux rostrally from the stomach into the esophagus P.B. Sullivan, 2008 Mechanisms of GER Pharynx • Transient LES relaxation • Intra-abdominal pressure • Reduced esophageal capacitance • Gastric compliance • Delayed gastric emptying UES Esophagus Mechanisms of Esophageal Complications Crural diaphragm Pylorus Angle of His • Impaired esophageal clearance • Defective tissue resistance • Noxious composition of refluxate LES Mechanisms of Airway Complications Stomach • Vagal reflexes • Impaired airway protection GERD GER is a pathological process and GERD refers to the symptom complex that arises as a result of that process. It is ironic that the learning deficit that usually accompanies neurological impairement also impairs the ability of the affected individual to communicate the main symptom of GERD which is pain P.B. Sullivan, 2008 GERD Chronic peptic esophagitis=>mucosal ulceration=>stricture formation Pain=>irritability and crying=>distonic movement of face and neck Chronic dysphagia=>behavioral food avoidance or aversion Vomiting, hematemesis, anemia, rumination and regurgitation Dental problem P.B. Sullivan, 2008 RESPIRATORY CONSEGUENCE OF GERD The association between GERD and respiratory complications (apnea, laryngitis, asthma/wheezing, chronic cogh, chronic pulmonary aspiration, recurrent pneumonia and progressive lung has injury) been recognized for decades P.B. Sullivan, 2008 ORALMOTOR IMPAIRMENT GERD La diagnosi => pHmetria esofagea => pasto baritato => esofagogastroduodenoscopia => Manometria esofagea pHmetria esofagea Monitoraggio prolungato del pH esofageo dimostra •per quanto tempo vi è acido nell’esofago (IR in %) •relazione tra i sintomi e l’evento RGE accessi di tosse FKT Pasto baritato Consente una precisa valutazione della anatomia del tubo digerente (frequenti le anomalie anatomiche nei bambini con danno neurologico) Pasto baritato Consente una valutazione (grossolana) della funzione di deglutizione che, tuttavia,viene meglio studiata con => Videofluoroscopia => Valutazione logopedica => Valutazione foniatrica In casi selezionati, la funzione di deglutizione viene studiata dal punto di vista manometrico Deglutizioni secche Deglutizioni umide Esofagogastroduodenoscopia Valuta le condizioni della mucosa esofagea, permettendo di diagnosticare la presenza di lesioni esofagitiche più o meno gravi Terapia medica Risultati spesso deludenti => procinetici (domperidone) => antiacidi (idrossido di MG e Al) => acido alginico => antisecretivi (ranitidina, omeprazolo, esomeprazolo) In pediatria va seguito lo schema “step up” (dal farmaco più maneggevole e con minor effetti collaterali al farmaco meno maneggevole e con più effetti collaterali) PPI antiH2 Ac. alginico procinetico Domperidone: 0.2 mg/Kg/dose 4 volte/die, 20’ prima dei pasti Ac. Alginico: 0.5 ml/Kg/dose 4 volte al giorno. 20’ dopo i pasti Ranitidina: 10 mg/Kg in 2 dosi al giorno PPI: 1-2 mg/Kg al giorno alla mattina Terapia medica Farmaci “non gastroenterologici” => baclofen => ondansetron Effect of baclofen on emesis and 24 hour esophageal pH in NI children with GER The GABA type B receptor agonist baclofen was recently reported to reduce reflux in adult patients with GERD reducing the incidence of transient lower esophageal sphincter relaxations 8 NI children with GER was studied. Baclofen (0.7 mg/Kg/die) was administered…in 3 divided doses 30’ before meals for 7 days J Pediatr Gastroenterol Nutr. 2004 Mar; 38(3):317 Results Emesis decreased in 6/8 patients (75%) pH monitoring parameters ¾N of refluxes 193 vs. 124 (39%) P 0.01 ¾RI 17 vs. 11 (40%) P 0.21 ¾N of long acid refluxes 11 vs. 4 (56%) P 0.02 ¾T of longest acid reflux 41’ vs. 27’ (37%) P 0.13 In conclusions: 1 week baclofen therapy…had significant effects on GERD in NI children J Pediatr Gastroenterol Nutr. 2004 Mar; 38(3):317 Ondansetron: a review of its use as an antiemetic in children Ondansetron is a selective serotonin 55-HT3 receptor antagonist. In dose ranging and large placeboplacebo-controlled trials, intravenous (0.075 to 0.15 mg/Kg) or oral (0.1 mg/kg) ondansetron was significantly more effective than placebo in preventing emesis in children undergoing surgery associated with a high risk of postop. nausea and vomiting Paediatr Drugs 2001; 3(6): 441 DA PEDGI For this very difficult population, I have noticed that often Baclofen or Tranzene or some other med prescribed by neurologist work better for vomiting or reflux than “our” medicines do (H2 blockers and PPIs) I use ondansetron 4 mg od – bid Adrian Jones, Professor of Pediatrics Edmonton, Alberta Canada Trattamenti “operativi“ NO medicina, NO chirurgia ¾sondino ng ¾sondino transpilorico Trattamenti “operativi“ NO medicina, NO chirurgia ¾Gastrostomia (chirurgica, percutanea endoscopica, laparoscopica) ¾Digiunostomia (chirurgica, percutanea endoscopica, laparoscopica) Gastrostomia Obiettivi •migliorare lo stato nutrizionale •evitare un riempimento eccessivo dello stomaco VIA GASTRICA pallone VANTAGGI DELLA GASTROSTOMIA Miglioramento dello stato nutrizionale Somministrazione sicura di farmaci e di altri trattamenti (stipsi) Impact of nutritional rehabilitation on GER in neurological impaired children 10 malnourished NI children (triceps skin fold thickness [TSF] below the 5th percentile) treated with aggressive nutritional rehabilitation, rehabilitation, fed through a PEG.
