An infant with delayed development and peripheral myopathy, nourished on a soy-based liquid diet deficient in carnitine, had gastrointestinal dysmotility manifested by postprandial vomiting, oral drooling, delayed gastric emptying and infrequent bowel movements. Oesophageal manometry showed a reduced lower oesophageal sphincter pressure for age with abnormal distal motility. Serum carnitine concentration was 9.9 mumol l-1. After dietary supplementation of carnitine the gastrointestinal symptoms resolved, oesophageal manometry returned to normal, and serum carnitine increased to 37.2 mumol l-1. Dietary carnitine deficiency in infancy may be a cause of smooth muscle dysmotility of the gastrointestinal tract.

Review of all reports involving anthelmintics in dogs and cats to the IAPIC between January 1, 1986 and August 10, 1988, revealed that ivermectin (extra-label use) and piperazine accounted for over 50% of the calls assessed as toxicoses and suspected toxicoses. Both ivermectin and piperazine are gamma-aminobutyric acid (GABA) agonists and their major effects appear to be on the central nervous system. Ivermectin toxicoses at estimated doses of greater than or equal to 100-less than 500 micrograms/kg were reported more than once only in the collies (n = 25) and Australian shepherds (n = 10); these two breeds accounted for 46% (69 of 150) of the toxicoses and suspected toxicoses calls in dogs. Ataxia, behavioral disturbances, tremors, mydriasis, weakness/recumbency, apparent blindness, hypersalivation/drooling (dogs only), and coma were the most commonly reported clinical signs in dogs and cats with suspected ivermectin toxicoses. Shock, dyspnea, vomiting, and ataxia were the most common clinical signs attributed to the microfilaricidal activity of ivermectin. Piperazine was the anthelmintic with the greatest number of reports of toxicoses and suspected toxicoses in cats. Piperazine neurotoxicity in cats and dogs usually was manifested by muscle tremors, ataxia, and/or behavioral disturbances within 24 hours after estimated daily dose(s) between 20 and 110 mg/kg.

The ingestion of hydrogen peroxide is usually benign. However, the ingestion of greater than 10% hydrogen peroxide can result in significant pathology. Two fatalities are reported in the literature involving children who ingested 27% and 40%. We report a case involving the ingestion of one mouthful of 35% hydrogen peroxide by a 26-month-old female. The child vomited spontaneously. In the Emergency Department the child was lethargic and had an episode of bright red emesis. Several hours later the child experienced a fainting episode followed by a brief respiratory arrest after which she began drooling bright red blood. The initial oral evaluation was negative. Endoscopic evaluation performed 16 hours postingestion revealed erosion of the cardia of the stomach, erythema of the lower esophageal sphincter, and an additional gastric burn. The child was observed for six days and discharged. Follow-up endoscopy performed 12 days postingestion showed only minimal hyperemia in the cardia of the stomach. Exposures to concentrated hydrogen peroxide should be managed aggressively.

Diagnosis of pulmonary disease due to inhalation (PDI) is based on the assumption that not all paediatric pulmonary disease is attributable to infection. Moreover, an accurate investigation of all typical signs of PDI is necessary: drooling, pouring of food from the nose, choking, frequent vomiting and regurgitation. Specific aetiological diagnosis is not difficult when PDI represents only the epiphenomenon of well defined diseases which have disturbed deglutition (e.g. premature birth, cerebral palsy, muscle disease). It is difficult but more important to find the cause of dysphagia when dysphagia itself represents the first sign of dysfunction of the autonomic nervous system (e.g. familial dysautonomy). There are different PDI due to oesophageal dysphagia, e.g. the anomalous artery which presses the oesophagus against the trachea, oesophageal duplication, achalasia. The most frequent cause is gastro-oesophageal reflux, although recently its role in producing symptoms at night in the asthmatic child in much less. Gastro-oesophageal reflux is increased by the Beta2, agonists, the corticosteroids and theophylline. Therefore these drugs, especially theophylline, have to be used with discretion, also if gastro-oesophageal reflux is only suspected (e.g. frequent vomiting by the infant). Anomalous communication between the oesophagus and airways, particularly the laryngotracheo-oesophageal cleft and the isolated tracheoesophageal fistula, are rare diseases and difficult to diagnose. Therefore diagnosis can be delayed for months or even years. Prognosis is extremely variable: repeated inhalation will, however, cause diffuse interstitial fibrosis or, more rarely, a bronchiectasic lesion.

We studied 80 children who presented to the emergency department (ED) with a complaint of coin ingestion to determine whether radiographs are necessary in all situations and to determine which symptoms or signs are predictive of esophageal coins. Radiographs were considered positive if the coin was in the esophagus. Radiographs were positive in 25 (31%) of patients, of whom 11 (14%) had no symptoms or signs in the ED. Fifty-five (69%) of the 80 patients had subdiaphragmatic foreign bodies (44 [55%]), or no foreign bodies (11 [14%]) seen on films. Fourteen (18%) of the children required removal of the coin. Variables correlating with positive radiograph, in order of significance, included localization, choking at ingestion, drooling in the ED, vomiting, and chest pain (P less than .05). Symptom type was predictive of radiographic findings, and it may be predictive of need for removal. All 14 patients with symptoms or signs in the ED had positive films, as compared to 11 of 66 (16.6%) with no symptoms (chi square = 33.555; P less than .001). Although this relationship is significant, the finding of esophageal foreign body in 17% of patients with no symptoms leads us to recommend that all patients have a chest radiograph if coin ingestion is suspected.

The ingestion of a caustic substance can lead to severe damage to the esophagus. Currently, esophagoscopy is recommended for all patients with a history of caustic substance ingestion because clinical criteria have not proved to be reliable predictors of esophageal injury. The records of 79 consecutive patients younger than 20 years who were first seen with a history of corrosive ingestion were reviewed. The presence or absence of three serious signs and symptoms--vomiting, drooling, and stridor--as well as the presence and location of oropharyngeal burns were compared with the findings on subsequent esophagoscopy. Fifty percent (7/14) of the patients with two or more of these serious signs and symptoms (vomiting, drooling, and stridor) had serious esophageal injury as compared with no positive endoscopic results in the group with none or only one of these clinical findings. The presence of oropharyngeal burns did not identify patients with serious esophageal injury. These results suggest that the presence of two or more signs or symptoms in patients with a history of caustic substance ingestion may be a reliable predictor of esophageal injury.

Five Karan Swiss crossbred (Sahiwal x Brown Swiss) calves were abruptly switched over from a diet of concentrate and maize fodder to ad libitum air dried Leucaena leucocephala leaves plus twigs. After 17 days on the L. leucocephala diet, 3 of the calves were supplemented with copper sulphate (10 mg/kg DM L. leucocephala) for 12 days. Thereafter all the calves were taken off the L. leucocephala diet and returned to the pre-experimental concentrate and maize fodder diet. While on the L. leucocephala diet, the average DM intake/d of L. leucocephala declined to 497 g within 3 weeks and all calves lost weight. This weight loss was reversed in the 3 calves that received copper sulphate, and all calves gained weight when they resumed the concentrate and maize fodder diet. The toxic effects of L. leucocephala feeding for 24 days were characterised by poor growth, emaciation, alopecia, loss of hair from the tail switch, ear and eye lesions, ulceration of the mouth region, drooling viscid saliva and vomiting of thick green saliva in one of the calves. Mean levels of 3,4 dihydroxypyridone (DHP) (mg/100 ml) were 30.35 +/- 13.52 and 55.57 +/- 13.77 on days 2 and 4 respectively in rumen liquor and up to 136.01 +/- 80.18 in urine. The mean ratios of mimosine: DHP of 3.14, 0.12 and 0.04 in feed, faeces and urine respectively revealed extensive degradation of mimosine to DHP in the calves fed the L. leucocephala diet and it was concluded the calves were unable to tolerate a diet consisting solely of L. leucocephala.

This two-year-old boy presented with a two-day history of vomiting and fever. He was diagnosed with acute otitis media four days before this incident. Repeated questioning revealed removal of a percutaneous enterostomy tube two weeks earlier with failure to pass the internal bumper in his stool. The child was in no distress, except for repeated emesis and drooling. A chest x-ray revealed a foreign body in the esophagus, and the patient underwent removal of the percutaneous endoscopic gastrostomy plastic bumper by endoscopy without incident.

Tetrahydrobiopterin (BH4) deficiencies are a heterogeneous group of disorders caused by a defect in two of the three enzymes involved in its biosynthesis or in the two recycling enzymes. Except for the deficiency of dehydratase, an enzyme catalyzing a reaction in the recycling pathway, all other variants of BH4 deficiency are characterized by developmental delay, progressive neurological deterioration, hypokinesis, drooling, swallowing difficulty, truncal hypotonia, increased limb tone, myoclonus and brisk deep tendon reflexes. A deficiency of guanosine triphosphate cyclohydrolase I (GTPCH), the first enzyme in the biosynthetic pathway of BH4, is described in a 14-month-old male infant with hyperphenylalaninemia, developmental delay, hypertonia of the extremities, seizures, feeding difficulties, and vomiting. Urinary pteridine screening revealed very low levels of neopterin and biopterin which was highly suggestive of GTPCH deficiency. Low cerebrospinal fluid concentrations of 5-hydroxyindoleacetic acid (5HIAA) and homovanillic acid concentrations, together with no detectable neopterin and decreased concentrations of biopterin and folate, agreed with the diagnosis of GTPCH deficiency. Subsequently measured neopterin and biopterin synthesis in cytokine-stimulated skin fibroblasts confirmed GTPCH deficiency, albeit indirectly. The patient showed marked improvement on a low-protein low-phenylalanine diet with neurotransmitter precursor administration. The favorable outcome in this patient clearly shows that not only newborns with elevated phenylalanine levels but also older children with neurological signs and symptoms should be screened for a BH4 deficiency in order to have maximum benefit of the treatment.

The aim of this study was to estimate the prevalence and severity of feeding and nutritional problems in children with neurological impairment within a defined geographical area. In a cross-sectional study, a validated questionnaire was sent to 377 parents of children (aged 4 to 13 years) on the Oxford Register of Early Childhood Impairments with oromotor dysfunction. The return rate was 72%. Of these, 93% had cerebral palsy; 47% were unable to walk; 78% had speech difficulty; and 28% continuous drooling of saliva. Gastrointestinal problems were commonly encountered: 59% were constipated; 22% had significant problems with vomiting, and 31% had suffered at least one chest infection in the previous 6 months. Feeding problems were prevalent: 89% needed help with feeding and 56% choked with food; 20% of parents described feeding as stressful and unenjoyable. Prolonged feeding times (3h/day) were reported by 28%. Only 8% of participants received caloric supplements and 8% were fed via gastrostomy tube. Even though 38% of respondents considered their child to be underweight, 64% of children had never had their feeding and nutrition assessed. The results highlight that feeding problems in children with neurological impairment are common and severe, causing parental concern. Many of these children would benefit from nutritional assessment and management as part of their overall care.
