RESUMO

OBJECTIVE: Functional gastrointestinal disorders are common gastrointestinal diseases. The pathophysiology is multifactorial and psychosocial distress worsens symptoms severity. Since the end of 2019 the world has been facing COVID-19 pandemic. The associated control measures have affected the psychological health of people. The aim of the present study is to evaluate the impact of the COVID-19 pandemic on the prevalence of functional gastrointestinal disorders among Italian children and adolescents. PATIENTS AND METHODS: The study sample is composed of 407 patients (187 males, 220 females), aged from 10 to 17 years. The mean age is 14.27 ± 2.24 years. The study was conducted through the Italian version of the Questionnaire on Pediatric Gastrointestinal Symptoms-Rome III Version.  The prevalence of each disorder has been calculated as the ratio of affected subjects for each disease and the total number of effective cases for that specific disease. RESULTS: The study demonstrates that the prevalence of Functional Gastrointestinal Disorder in Italian children, during the COVD-19 pandemic, is higher, compared with the one reported in the previous studies. The most frequent disorders are Abdominal Migraine and Irritable Bowel Syndrome. CONCLUSIONS: Our study is the first one which provides data of the prevalence of Functional gastrointestinal disorders in sample of Italian adolescents, during the COVID-19 pandemic. The study underlines the need to focus on stress management, in order to reduce the effects of the lockdown on the psychological wellness of the youngest.

RESUMO

Presentamos un niño previamente sano de dos años con importante distensión abdominal al que después de varias intervenciones con escasa respuesta se diagnosticó aerofagia patológica. La aerofagia patológica en pediatría es un trastorno infrecuente, casi exclusivo en niños con enfermedad neurológica de base. Puede ser motivo de múltiples exámenes complementarios y tratamientos agresivos innecesarios. La reciente publicación de un caso asocia la aerofagia con un novedoso concepto, la disinergia abdómino-frénica


We report the case of a previously healthy 2-year-old child who presented with significant abdominal distension. After several interventions that proved ineffective, pathologic aerophagia was eventually diagnosed. In pediatrics, pathologic aerophagia is an uncommon disorder that almost exclusively affects children with an underlying neurological condition. It may lead to multiple diagnostic tests and unnecessary aggressive therapies. A recent case report associated aerophagia with a novel concept of abdomino-phrenic dyssynergia

RESUMO

BACKGROUND: Eructation is a physiologic event which allows gastric venting of swallowed air and most of the time is not perceived as a symptom. This is called gastric belching. Supragastric belching occurs when swallowed air does not reach the stomach and returns by mouth a short time after swallowing. This situation may cause discomfort, life limitations and problems in daily life. OBJECTIVE: Our objective in this investigation was to evaluate if gum chewing increases the frequency of gastric and/or supragastric belches. METHODS: Esophageal transit of liquid and gas was evaluated by impedance measurement in 16 patients with complaint of troublesome belching and in 15 controls. The Rome III criteria were used in the diagnosis of troublesome belching. The esophageal transit of liquid and gas was measured at 5 cm, 10 cm, 15 cm and 20 cm from the lower esophageal sphincter. The subjects were evaluated for 1 hour which was divided into three 20-minute periods: (1) while sitting for a 20-minute base period; (2) after the ingestion of yogurt (200 mL, 190 kcal), in which the subjects were evaluated while chewing or not chewing gum; (3) final 20-minute period in which the subjects then inverted the task of chewing or not chewing gum. In gastric belch, the air flowed from the stomach through the esophagus in oral direction and in supragastric belch the air entered the esophagus rapidly from proximal and was expulsed almost immediately in oral direction. Air swallows were characterized by an increase of at least 50% of basal impedance and saliva swallow by a decrease of at least 50% of basal impedance, that progress from proximal to distal esophagus. RESULTS: In base period, air swallowing was more frequent in patients than in controls and saliva swallowing was more frequent in controls than in patients. There was no difference between the medians of controls and patients in the number of gastric belches and supragastric belches. In six patients, supragastric belches were seen at least once during the 20-minute base period. None of the controls had supragastric belches. In the control group, the ingestion of yogurt caused no significant alteration in the number of air swallows, saliva swallows, gastric belches and supragastric belches. In the patient group, there was an increase in the number of air swallows. If the subjects were chewing gum during this 20-minute period, there was an increase in the number of saliva swallows in both groups, without alterations of the number of air swallow, gastric belches and supragastric belches. There was no alteration in the number of the saliva swallows, air swallows, gastric belches and supragastric belches in both groups for subjects who did not chew gum in the 20-40 minute period after yogurt ingestion. When the subjects were chewing the gum, there was an increase in saliva swallows in the control and patients groups and in air swallows in the patients group. CONCLUSION: Gum chewing causes an increase in saliva swallowing in both patients with excessive belching and in controls, and an increase in air swallowing in patients with excessive belching 20 minutes after yogurt ingestion. Gum chewing did not increase or decrease the frequency of gastric or supragastric belches.

ContextoEructação é um evento fisiológico que permite a eliminação de gás presente no estômago, geralmente não percebida como sintoma, situação identificada como eructação gástrica. Eructação supragástrica ocorre quando o ar deglutido não vai ao estômago, mas retorna do esôfago imediatamente após ser deglutido; situação que causa desconforto e limitações ao paciente.ObjetivoO objetivo desta investigação foi avaliar se goma de mascar aumenta a frequência de eructação gástrica e/ou supragástrica.MétodosO trânsito de líquido e gás foi avaliado por impedância in 16 pacientes com queixas de eructação excessiva e 15 controles. O diagnóstico de eructação excessiva foi feito tendo em consideração os critérios descritos no Roma III. O trânsito pelo esôfago foi medido por sensores de impedância localizados a 5 cm, 10 cm, 15 cm e 20 cm do esfíncter inferior do esôfago. Os indivíduos foram avaliados sentados em uma cadeira durante um período basal de 20 minutos, outro período de 20 minutos após a ingestão de iogurte (200 mL, 190 kcal), mastigando ou não goma de mascar, e em outro período por mais 20 minutos no qual invertiam o fato de mastigarem ou não goma de mascar. Na eructação gástrica o ar vinha do estômago em direção proximal, e na eructação supragástrica o ar entrou no esôfago e foi imediatamente eliminado em direção proximal. A deglutição de ar foi caracterizada pelo aumento em pelo menos 50% do valor da impedância e a deglutição de saliva pela diminuição em pelo menos 50% do valor da impedância, que progredia da parte proximal do esôfago para a parte distal.ResultadosNo período basal a deglutição de ar foi mais frequente nos pacientes do que nos controles, e a deglutição de saliva mais frequente nos controles do que nos pacientes. Não houve diferenças na mediana entre os resultados de controles e pacientes no número de eructações gástricas e supragástricas. Em seis pacientes ocorreram eructações supragástricas, o que não aconteceu em nenhum controle. Entre os controles a ingestão de iogurte não alterou a frequência de deglutição de ar, deglutição de saliva, eructações gástricas e eructações supragástricas. No grupo de pacientes houve aumento da deglutição de ar. Mastigar a goma durante este período causou aumento da deglutição de saliva, nos dois grupos, sem alterações na frequência de deglutição de ar, eructação gástrica e eructação supragástrica. No período entre 20 e 40 minutos após a ingestão do iogurte, se a pessoa não mascava a goma, não havia mudança na frequência de deglutição de saliva, deglutição de ar, eructações gástricas e eructações supragástricas. Quando a pessoa mascava a goma, houve aumento da deglutição de saliva nos dois grupos e de deglutição de ar no grupo de pacientes.ConclusãoGoma de mascar causa aumento da deglutição de saliva em pacientes com eructações excessivas e controles, e aumento da deglutição de ar em pacientes 20 minutos após a ingestão de iogurte. Goma de mascar não aumenta ou diminui a frequência de eructação gástrica ou eructação supragástrica.

RESUMO

STUDY OBJECTIVES: Continuous positive airway pressure (CPAP), the mainstay treatment for obstructive sleep apnea (OSA), involves administration of air under pressure to the upper airway. A well-known but poorly understood side effect of positive airway pressure therapies is aerophagia, air entering the esophagus and stomach rather than the lungs. Gastric distension, a consequence of aerophagia, can increase gastroesophageal reflux (GER) by increasing transient lower esophageal sphincter relaxations, the most common cause of reflux. This study aimed to determine: (i) the prevalence of aerophagia symptoms in a group of OSA patients on CPAP therapy, and (ii) whether aerophagia symptoms are related to an increase in prevalence of GER symptoms. METHODS: Consecutive OSA patients undergoing polysomnography for the purpose of optimizing their CPAP therapy completed a validated questionnaire regarding GER symptoms and aerophagia symptoms. Complete datasets were collected for 259 individuals (203 males). RESULTS: The group with aerophagia symptoms (n = 130) had a greater prevalence of frequent (≥ once a week) GER symptoms (29% vs. 10%, p < 0.05) and nighttime GER symptoms (9 vs. 2%, p < 0.05) than those without aerophagia (n = 129). The group with nighttime GER symptoms (n = 27) had a greater prevalence of aerophagia symptoms (63% vs. 23%, p < 0.05) than those without nighttime GER symptoms (n = 232). CONCLUSIONS: In patients with OSA being treated with CPAP, the prevalence of GER and nighttime GER symptoms is greater in those with symptoms of aerophagia than those without. CPAP-induced aerophagia might precipitate GER, particularly nighttime GER, by exacerbating transient lower esophageal relaxations through gastric distension.

RESUMO

Pathologic aerophagia is sometimes seen in patients with neurologic disorders. It rarely causes massive bowel distention, ileus, and volvulus. Here, we report the use of esophagogastric separation and abdominal esophagostomy via jejunal interposition to prevent bowel distention caused by severe aerophagia in 2 patients with neurologic disorders in whom the usual nonoperative methods of management failed. In both cases, swallowed air was evacuated via the jejunostomy, eliminating bowel distention. This operation may be useful in patients with neurologic disorders associated with severe aerophagia.

RESUMO

Air swallowing can occur as a psychogenic phenomenon, because of abnormal anatomy, or during non-invasive positive pressure ventilation. Gross distension of the stomach with air can have severe consequences for the respiratory and gastrointestinal systems. We report the case of a 62-year-old man with severe dynamic hyperinflation due to chronic obstructive pulmonary disease, who developed respiratory failure requiring intubation a few hours after radical prostatectomy. Following a percutaneous tracheostomy and weaning of sedation on day six, his abdomen began to enlarge progressively. X-rays revealed massive gastric distension due to air swallowing, which continued despite all efforts to optimise therapy. The use of an underwater seal drainage system on a nasogastric tube improved ventilation and ultimately aided weaning from mechanical support.

RESUMO

STUDY OBJECTIVES: Aerophagia is a complication of continuous positive airway pressure (CPAP) therapy for sleep disordered breathing (SDB), whereupon air is forced into the stomach and bowel. Associated discomfort can result in CPAP discontinuation. We hypothesize that aerophagia is associated with gastroesophageal reflux disease (GERD) via mechanisms involving GERD related lower esophageal sphincter (LES) compromise. METHODS: Twenty-two subjects with aerophagia and 22 controls, matched for age, gender, and body mass index, who were being treated with CPAP for SDB were compared in regard to clinical aspects of GERD, GERD associated habits, SDB severity as measured by polysomnography, and mean CPAP pressure. RESULTS: More subjects with aerophagia had symptoms of GERD (77.3% vs. 36.4%; p < 0.01) and were on GERD related medications (45.5% vs. 18.2%, p < 0.05) than controls. Regarding polysomnography, mean oxygen saturation percentages were lower in the aerophagia group than controls (95.0% vs. 96.5%, p < 0.05). No other differences were observed, including mean CPAP pressures. No one in the aerophagia group (vs. 27.3% of the control group) was a current tobacco user (p < 0.01). There was no difference in caffeine or alcohol use between the 2 groups. CONCLUSIONS: These results imply aerophagia is associated with GERD symptoms and GERD related medication use. This finding suggests a relationship between GERD related LES pathophysiology and the development of aerophagia in patients with SDB treated with CPAP.

RESUMO

The etiology of abnormal belching is not known. Currently, it is being subsumed under "functional gastroduodenal disorders." Here, we report the unusual case history of a patient who developed aerophagia and consecutive excessive belching in association with herpes simplex encephalitis. The case report adds to the limited information about potential organic geneses of belching. Implications for possible medical therapies are discussed.

RESUMO

Noninvasive positive ventilation has undergone a remarkable evolution over the past decades and is assuming an important role in the management of both acute and chronic respiratory failure. Long-term ventilatory support should be considered a standard of care to treat selected patients following an intensive care unit (ICU) stay. In this setting, appropriate use of noninvasive ventilation can be expected to improve patient outcomes, reduce ICU admission, enhance patient comfort, and increase the efficiency of health care resource utilization. Current literature indicates that noninvasive ventilation improves and stabilizes the clinical course of many patients with chronic ventilatory failure. Noninvasive ventilation also permits long-term mechanical ventilation to be an acceptable option for patients who otherwise would not have been treated if tracheostomy were the only alternative. Nevertheless, these results appear to be better in patients with neuromuscular/-parietal disorders than in chronic obstructive pulmonary disease. This clinical review will address the use of noninvasive ventilation (not including continuous positive airway pressure) mainly in diseases responsible for chronic hypoventilation (that is, restrictive disorders, including neuromuscular disease and lung disease) and incidentally in others such as obstructive sleep apnea or problems of central drive.

RESUMO

Nausea, gastroparesis, and aerophagia are gastrointestinal phenomena that have variable impact on affected patients. The causes of nausea are varied; treatment of these conditions relates to the underlying etiology. Antiemetic agents acting on several distinct receptor subtypes produce benefits in distinct patient subsets. Gastroparesis is characterized by delays in gastric emptying, usually defined scintigraphically. Standard care of gastroparesis relies on dietary modification, antiemetic drug therapy, and initiation of medications that stimulate gastric motor activity. Recent advances include pyloric injection of botulinum toxin and surgical implantation of an electrical neurostimulator. Other surgical therapies are reserved for refractory cases. Aerophagia presents in individuals of normal and impaired cognitive function, most commonly with symptoms of overdistension or eructation. There are no pharmaceutical remedies for this condition; thus, therapy relies on behavioral treatments.

RESUMO

BACKGROUND: While the mechanism of aerophagia remains unclear, the frequency of clenching has been reported to be increased when under stress. We hypothesized that, via the swallowing reflex, chronic air swallowing was induced through a "learned habit" of the oral cavity, which was acquired through psychological factors. This study examined whether the habitual repeated swallowing in the oral cavity was a process of aerophagia. METHODS: After continuous experimental saliva swallowing, changes in the stomach bubble were examined by abdominal X-rays in a standing position. The subjects included 9 males and 10 females aged 20 to 36 years that were without organic disease in the pharynx and nasal cavity. X-ray images were digitized, and the area of the stomach bubble was measured by tracing. RESULTS: A close correlation was revealed in the stomach bubble area between posteroanterior and lateral views in six males (p<0.001, r = 0.910). In 3 males and 10 females, the area of the stomach bubble by posteroanterior view after 30 swallows was significantly increased compared with that before swallowing (p = 0.004). CONCLUSIONS: In the present study, abdominal X-rays confirmed that frequent saliva swallowing expanded the stomach bubble.
