Aspiration of oil into the lung can lead to pneumonia. The degree of severity depends on the quantity and the nature of the oil. We report the case of a 43-year-old woman with no medical history who was hospitalized for suspected infectious pneumonia. Explorations led to the conclusion that aspiration pneumonia was secondary to the ingestion of oil favored by gastroesophageal reflux.

Bronchiolitis obliterans and its clinical correlate bronchiolitis obliterans syndrome (BOS) are a major cause of morbidity and mortality following lung transplantation. Gastroesophageal reflux disease (GERD) may be a contributing factor for the development of BOS. Since 2002, all recipients of lung and heart-lung transplantation at our institution have been routinely investigated for GERD. In this observational study, we report on the prevalence of GERD in this population, including all pediatric patients undergoing single (SLTx) or double (DLTx) lung transplantation or heart-lung (HLTx) transplantation from January 2003-May 2004. GERD was assessed 3-6 months after transplantation by 24-hr pH testing. The fraction time (Ft) with a pH < 4 within a 24-hr period was recorded. Spirometry data, episodes of confirmed acute rejection, and demographic data were also collected. Ten transplant operations were performed: 4 DLTx, 1 SLTx, and 5 HLTx. Nine patients had cystic fibrosis. One patient had end-stage pulmonary disease secondary to chronic aspiration pneumonia and postadenovirus lung damage. Of 10 patients tested, 2 had severe GERD (Ft > 20%), 5 had moderate GERD (Ft 10-20%), 2 had mild GERD (Ft 5-10%), and 1 had no GERD. The only patient in this group with no GERD had a Nissen fundoplication pretransplant. All study patients were asymptomatic for GERD. All patients with episodes of rejection had moderate to severe GERD posttransplant. There was no association between severity of GERD and peak spirometry results posttransplant. Moderate to severe GERD is common following lung transplantation in children.

The usefulness of radiologic examination in the diagnosis of aspiration pneumonia in infants. The aim of the study was to estimate whether the connection between the localisation and radiological findings on the plain X-ray chest examination exists in the group of 121 infants and young children, age 1 to 24 month (77 boys and 44 girls), treated for pneumonia and gastroesophageal reflux disease (GERD), established by 24-hour esophageal pH-monitoring. In all children the diagnosis of pneumonia were made on admission to hospital by physical and X-ray chest examinations. GERD, in accordance with consensus ESPAGAN, was diagnosed in the group of 65 children. Children with abnormal results of pH-monitoring had significantly more changes in the lower parts of the right lung and in the intermediate and the lower parts of the left lung. There were no difference in radiological appearance between the changes suspected to the aspiration etiology and other pneumonic changes in the group of 56 children with normal pH-investigation. Additionally, there was no significant difference in the frequency of atelectasis, emphysema and/or enlargement of the thymus between both groups.

We evaluated the role of gastro-esophageal reflux (GER) in aspiration pulmonary disease. To explore swallowing function, we measured the latent time (LT) on the swallowing provocation test in patient with non-aspiration pneumonia (PN, n=5), aspiration pneumonia (AP, n=8), post-gastrectomy aspiration pneumonia (PGAP, n=8), gastro-esophageal reflux disease (GERD, n=12) and normal group (NR, n=7). LT was prolonged in the AP (2.83 +/- 1.66 sec p < 0.01), PGAP (2.58 +/- 1.40 sec p < 0.05) and GERD (2.40 +/- 1.70 sec p < 0.05) groups compared with NR (1.04 +/- 0.56 sec) group, but not prolonged in PN (1.46 +/- 0.75 sec) group. LT was also prolonged when swallowing was provoked during inspiration both in AP (3.61 +/- 2.60 sec vs. 2.73 +/- 2.19 sec, p < 0.05) and NR (2.13 -/+ 1.12 sec vs. 1.49 +/- 1.30 sec, p < 0.01). Protected specimen brushing (PSB) was employed to detect pathogenic organisms in the PN (n=70), AP (AP, n=27) and PGAP (n=15) groups. Gram-negative rods were most frequently detected in the PGAP (p=0.008) group. We conclude that GER plays an important role in aspiration pulmonary disease not only as a source of aspirating agent but also as a disturbing factor of swallowing function.

We discuss here the indication and complications of tracheostomy performed in 57 home-care pateints with severe motor and intellectual disabilities (SMID) during the past 13 years at our hospital. Thirty-five cases underwent tracheostomy following emergency endotracheal intubation for acute respiratory failure. Recently, the number of cases without preceding endotracheal intubation have increased. Many patients underwent tracheostomy at the age of 1 to 4 years and 10 to 14 years. The quality of life (QOL) of almost all the patients without preceding intubation markedly improved, as well as that of their families, and they were able to return to home. The most decisive reason for tracheostomy was secretions and recurrent aspiration pneumonia in 8 patients, gastroesophageal reflux in 4 and upper airway obstructions in 3. Several complications of tracheostomy were observed: tracheal granulations in 9 patients, tracheal malacia in 8, and tracheoinnominate artery fistula in 5. Among 8 patients with tracheal malacia, bleeding from the tracheoinnominate artery fistula occurred in 3. In 7 patients, self-made long tracheostomy tubes were necessary for the initial management of the tracheal malacia or tracheal granulations. Subsequently, made-to-order long tracheostomy tubes were used in three of these patients. In 12 patients, improved endotracheal T-tube with the tip sealed on the vocal cord side was used to prevent aspiration. Home-care SMID patients with respiratory disturbance require tracheostomy timely performed, followed by careful observation to prevent postoperative complications.

Gastroparesis is a serious complication of lung transplantation that can lead to weight loss, gastroesophageal reflux disease, and recurrent aspiration pneumonia. We present 2 lung allograft recipients in whom gastroparesis resolved with the use of transcutaneous electrical nerve stimulation (TENS). In both patients, severe symptoms of gastroparesis refractory to medical therapy were completely ablated after 20 and 30 days of therapy. Both patients are currently asymptomatic with a normal diet, without the use of promotility agents. Lung transplant recipients with severe gastroparesis can derive significant benefit from TENS.

Aspiration of oropharyngeal contents is a constant threat for elderly patients fed via a nasogastric tube (NGT). Colonization of the oropharynx of these patients by pathological flora and the development of biofilms on the feeding tube has been documented recently. In addition, the presence of the NGT may interfere with the gastro-oesophageal sphincter, leading to gastro-oesophageal reflux. Thus, the passage of pathogenic bacteria in both directions is facilitated. The purpose of this study was to explore the microbiota of the gastric juice and the oropharynx in NGT-fed elderly patients. Samples of gastric juice were drawn after an overnight fast, and microbial cultures and direct pH measurement were performed. Concomitant cultures were obtained from the oropharynx. Overall, 107 gastric and oropharyngeal cultures were obtained from 52 subjects. Pathogenic flora (Gram-negative bacteria or Staphylococcus aureus) were isolated from 74% of stomach samples and from 69% of oropharynx samples. Proteus spp. (26%) and Escherichia coli (22%) were the most common isolates in the gastric juice, and Proteus spp. (24%) and Pseudomonas spp. (21%) were the most common isolates in the oropharynx. Similarity in the composition of the oropharynx and gastric flora was observed in most cases. The gastric pH was relatively high (4.57 +/- 0.65 at 3 h after feeding and 4.2 +/- 0.9 at 12 h after feeding) and was highly correlated with the isolation of pathogenic bacteria (r = 0.58, P < 0.01). These results support the view that in addition to the oropharynx, the stomach of NGT-fed elderly patients constitutes a reservoir of pathogens that could be associated with the risk of aspiration pneumonia. The cause of the high gastric pH and its relation to pathogenic bacteria warrants further study.

Gastroesophageal reflux disease is the most common and expensive digestive disease with complex and multi-factorial pathophysiologic mechanisms. Transient inappropriate relaxation of the lower esophageal sphincter is the predominant mechanism in the majority of patients with mild to moderate disease. Hiatal hernias and a reduced lower esophageal sphincter pressure have a significant role in patients with moderate to severe disease. Typical manifestations of gastroesophageal reflux disease include heartburn, regurgitation, and dysphagia. Atypical symptoms, such as noncardiac chest pain, pulmonary manifestations of asthma, cough, aspiration pneumonia, or ENT manifestations of globus and laryngitis, can be seen in patients with or without typical symptoms of gastroesophageal reflux disease. Endoscopy and ambulatory pH tests are best to evaluate the anatomic and physiologic impact ofgastroesophageal reflux disease. Complications of chronic gastroesophageal reflux disease include peptic strictures and Barrett metaplasia. Barrett esophagus is a major risk factor for esophageal adenocarcinoma, and upper endoscopy with surveillance biopsies is recommended for patients with Barrett esophagus. Medical therapy with anti-secretory agents (H2 blockers and proton pump inhibitors) is effective for most patients with gastroesophageal reflux disease. Surgical fundoplications and endoscopic treatment modalities are mechanical treatment options for patients with gastroesophageal reflux disease.

We report on the complication of gastroesophageal reflux (GER) in four patients with lower brainstem dysfunction. These patients suffered from perinatal asphyxia, cerebellar hemorrhage, or congenital dysphagia of unknown origin and showed facial nerve palsy, inspiratory stridor due to vocal cord paralysis, central sleep apnea, and dysphagia, in various combinations. Naso-intestinal tube feeding was introduced in all of the patients due to recurrent vomiting and aspiration pneumonia resulting from GER. T2-weighted magnetic resonance (MR) imaging revealed symmetrical high intensity lesions in the tegmentum of the lower pons and the medulla oblongata in two of the patients, and pontomedullary atrophy in another patient. In normal subjects, lower esophageal sphincter contraction is provoked by distension of the gastric wall, through a vago-vagal reflex. Since this reflex arc involves the solitary tract nucleus, where the swallowing center is located, the association of dysphagia and GER in the present patients is thought to result from the lesions in the tegmentum of medulla oblongata. We propose the term "dysphagia-GER complex" to describe the disturbed motility of the upper digestive tract due to lower brainstem involvement. In children with brainstem lesions, neurological assessment of GER is warranted, in addition to the examination of other signs of brainstem dysfunction, including dysphagia and respiratory disturbance.

The aim of the study was to conduct a survey using a dedicated questionnaire to estimate feeding difficulties, gastrointestinal involvement and weight gain in a population of 118 Duchenne muscular dystrophy (DMD) patients (age range 13.80-35.8 years). All the answers were entered in a database and the data analysed subdividing the cohort into age groups (3-9, 9-13, 13-18, 18-24, 24-30, 30-36 years). The results indicate that chewing difficulties are frequent and become increasingly present with age, associated with a progressive increase of the duration of meals. Episodes of choking or other clinical signs of swallowing difficulties are in contrast much less frequent even after age 18. Aspiration pneumonia were also not very frequent and only occurred in 7/118. Clinical signs of gastroesophageal reflux requiring treatment were only found in 5 while 43/118 complained of constipation requiring treatment. Very few of our patients had their weight above 2 SD (n = 4) and this was always found in patients between 9 and 18 years while after this age there was an increasing number of patients with weight below 2 SD. The results of our survey suggest that although choking is one of the most feared complications in patients with DMD, clinical signs of swallowing abnormalities are infrequent when collecting clinical information retrospectively. Further studies using an objective evaluation such as videofluoroscopy are needed to identify minor signs that may not be obvious on clinical examination.
