While single dose activated charcoal is effective in preventing drug absorption, repeated doses not only prevent absorption but also can increase systemic drug clearance. The mechanism for the latter effect may involve interruption of enterohepatic recycling and/or promotion of drug exsorption from the systemic circulation into the gut lumen. A comprehensive review of reported studies in volunteer subjects and overdose patients showed that repeated dose activated charcoal markedly decreased the half-life and/or increased the clearance of a wide range of drugs. Side-effects of the treatment were infrequent, but included aspiration pneumonia, diarrhoea and constipation. The addition of laxatives to repeated dose charcoal treatment did not offer any significant increase in drug clearance and is not recommended. It is suggested that the optimal regimen for the use of repeat dose activated charcoal in acute drug intoxications is an initial dose of 75-100 g, followed by 50 g every 4 hours until the risks of systemic drug toxicity are reduced to an acceptable level.

Forty-four cases of botulism occurred in infants in Southeastern Pennsylvania between 1976 and 1983. Forty-three were caused by Clostridium botulinum type B. Progressive weakness necessitated ventilatory support in 39 infants. Complications during hospitalization included otitis media in 13 patients and aspiration pneumonia in 11. Eight infants developed the syndrome of inappropriate secretion of antidiuretic hormone and two developed adult respiratory distress syndrome. One infant died of progressive bradycardia despite adequate control of ventilation. Manifestations of autonomic nervous system dysfunction recognized on admission to the hospital were constipation, distention of the urinary bladder, and decreased salivation and tearing. During hospitalization, some infants had unexpected fluctuations of skin color, blood pressure, and heart rate. Infants' strength improved despite persistent intestinal elaboration of toxin. C botulinum was isolated from seven of nine home or work environments sampled. All 44 infants were white and were receiving breast milk at the time of onset of symptoms. The majority had first feedings of nonhuman food substances within 4 weeks prior to onset of symptoms. Delineation of fecal flora in seven infants revealed predominance of enterobacteriaceae. Perturbations of intestinal flora during infancy, especially at weaning, may cause transient permissiveness to colonization by C botulinum.

Jejunostomy is a surgical procedure by which a tube is situated in the lumen of the proximal jejunum, primarily to administer nutrition. There are many techniques used for jejunostomy: longitudinal Witzel, transverse Witzel, open gastrojejunostomy, needle catheter technique, percutaneous endoscopy, and laparoscopy. The principal indication for a jejunostomy is as an additional procedure during major surgery of the upper digestive tract, where irrespective of the pathology or surgical procedures of the esophagus, stomach, duodenum, pancreas, liver, and biliary tracts, nutrition can be infused at the level of the jejunum. It is also used in laparotomy patients in whom a complicated postoperatory recovery is expected, those with a prolonged fasting period, those in a hypercatabolic state, or those who will subsequently need chemotherapy or radiotherapy. As a sole procedure it is advised for neurologic and congenital illnesses, in geriatric patients who pose difficult care demands, and for patients with tumors of the head and neck. The complications seen with jejunostomy can be mechanical, infectious, gastrointestinal, or metabolic. The rate of technical complications of the Witzel longitudinal technique is 2.1%, for the transverse Witzel up to 6.6%, for the Roux-en-Y 21%, for open gastrojejunostomy from 2%, and for the needle catheter technique from 1.5% with 0.14% mortality. The percutaneous endoscopic procedures have as much as a 12% complication rate; no figures exist for laparoscopy. The complications are moderate and severe: tube dislocation, obstruction or migration of the tube, cutaneous or intraabdominal abscesses, enterocutaneous fistulas, pneumatosis, occlusion, and intestinal ischemia. The infectious complications are aspiration pneumonia and contamination of the diet. The gastrointestinal complications are diarrhea 2.3% to 6.8%, abdominal distension, colic, constipation, nausea, and vomiting. The metabolic complications are hyperglycemia 29%, hypokalemia 50%, water and electrolyte imbalance, hypophosphatemia, and hypomagnesemia. These complications are secondary to inadequate selection of nutrition relative to the characteristics of the patient, to inadequate management of the mixture, and to deficient clinical care. The ideal jejunostomy technique depends on the material resources but more importantly on the experience of the surgeon. The benefits of jejunostomy justify the risks.

Aicardi syndrome is an X-linked-dominant condition characterized by infantile spasms, agenesis of the corpus callosum, and chorioretinal lacunae. We reviewed the Aicardi Syndrome Foundation's compilation of family-based, self-reported questionnaires for the year 2000. Information was obtained from 77 females with Aicardi syndrome regarding developmental milestones, seizure frequency, seizure classification, antiepileptic drug use, and medical problems. Patient ages ranged from 1 to 25 years (mean = 7.2 years). All patients were significantly developmentally delayed with milestones ranging from 2 to 36 months. Of the patients, 91% attained milestones no higher than 12 months. Seizures were reported in 92% of patients and occurred daily in 67%. Infantile spasms were the most common seizure type observed in 17%, although a variety of other seizure types were also reported. Multiple antiepileptic drugs were used in these patients with 73% of patients taking two or more antiepileptic drugs. Five patients had a vagal nerve stimulator implanted, and one patient underwent a hemispherectomy. The most common medical problems cited included scoliosis, constipation, gastroesophageal reflux, aspiration pneumonia, and otitis media, but overall health was perceived to be good. Our review demonstrates the spectrum of developmental disabilities, epilepsy severity, and prognosis in a large group of Aicardi patients.

A retrospective study was performed to determine the predisposing factors associated with the complications of ingested gastrointestinal (GI) tract foreign bodies (FBs) in children who had surgical or endoscopic removal. The study was performed in 161 children who had endoscopic or surgical removal. The clinical data were evaluated in two groups. In groups I and II, respectively, 135 patients with no complications and 26 patients with complications were analyzed. The relative risk analysis was performed for the risk factors. The number of the patients with an accurate history and the radiopaque FBs was significantly higher in group I. Metal, especially sharp objects, and food plugs obstructing a diseased esophagus were the most common FBs found in group II. The majority of the FBs of both groups were entrapped in esophagus, the number of the FBs distal to esophagus was significantly higher and duration of lodgment was significantly longer in group II. Esophageal abrasion, laceration and bleeding, complete esophageal obstruction, caustic injury, severe esophageal stricture, laryngeal edema, recurrent aspiration pneumonia, loss of weight, intestinal perforation, constipation and intestinal obstruction were determined as complications. The relative risk was >1 for duration of lodgment more than 24 h, for sharp or pointed objects, button batteries, nonopaque objects, diseased esophagus and for the objects located below the upper third of esophagus. Type, radiopacity, location and duration of the ingested GI tract FB determine the outcome. A delayed diagnosis is the most significant factor increasing the risk of complications. Physician must maintain a high index of suspicion and a more extensive history; physical examination and radiodiagnostic investigation should be obtained in suspected cases.

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.

A 6-year-old boy with multiple severe disabilities was admitted with acute and progressive dyspnoea. A new percutaneous endoscopic gastrostomy (PEG) catheter had been placed 2 weeks earlier, during which the old catheter was cut and left in the stomach. Radiological assessment revealed pneumonia and a traumatic fistula between the oesophagus and the left main bronchus. Respiratory support was required. The patient recovered after oesophagoscopic removal of the remaining portion of the PEG catheter. A 7-year-old boy with multiple severe disabilities presented with an acutely reduced level of consciousness, vomiting and progressive dyspnoea. Chest x-ray revealed signs of aspiration pneumonia and, after respiratory problems worsened, a foreign object in the oesophagus. The foreign object was likely the remaining portion of a PEG catheter that was removed 12 months earlier. The patient was discharged in good condition a few days after oesophagoscopic removal of the remaining catheter. PEG is a commonly used method for enteral feeding in children. The Dutch guideline on enteral feeding in children indicates that endoscopic removal of the PEG catheter is often necessary. In daily practice, however, endoscopic removal is not always performed. To avoid serious complications, authors recommend endoscopic removal ofthe silicon disk when replacing or removing a PEG catheter in children aged less than 6 years and all children with mental retardation, prior laparotomy or constipation. Endoscopic removal of the disk should be considered in all other children if the disk is not passed in stool within 2 weeks and an x-ray shows that the disk is in the oesophagus, stomach or proximal intestine.

Ketogenic diet (KD) is known to be effective in intractable epilepsy. However, the role of KD in refractory status epilepticus (RSE) has not been well described. The aim of this study is to explore the role of KD in patients with RSE. We retrospectively reviewed the medical records of four children and one adult with RSE between October 2006 and August 2010. All presented with status epilepticus (SE) that was presumed to be associated with viral encephalitis. After we failed to control the seizures with standard measures for SE, we tried KD. The overall seizure frequency decreased to <50% of baseline in median eight (1-19) days. At one month of KD, two patients were seizure-free, one patient showed >90% seizure reduction, and the others had >75% decrease without generalized seizures. With improvement in the RSE, we were able to taper the antiepileptic drugs (AEDs) and wean patients from prolonged mechanical ventilation. The adverse events of KD in RSE included aspiration pneumonia, gastroesophageal reflux, constipation, and hypertriglyceridemia. Those results demonstrate that KD can be a valuable therapeutic option for patients with RSE.

This case study compares two different clinical outcomes for a patient with a long-standing psychotic disorder prescribed clozapine on two occasions. During the first trial, clozapine was used at a higher dose for this patient (350-450mg/day) and included clinically significant sialorrhea, pneumonia, and pneumonia-like illnesses requiring immediate medical intervention including hospitalization. There were also patient complaints of fatigue, cough, choking, and constipation leading to poor adherence. Clozapine was discontinued when the patient withdrew his consent due to side effects, despite his awareness of its benefits, including reduction of command hallucinations and irritability. The second clozapine trial was associated with lower daily doses and therapeutic serum blood levels. The patient was actively participating in and adhering to the medication plan. A very narrow window of clozapine dose was exceeded for two days and the patient complained of hypersalivation, cough, and lethargy. He was subsequently hospitalized for a two week period to treat aspiration pneumonia. This hospitalization helped establish the ideal daily dose of clozapine for this patient and also brought the relationship between aspiration pneumonia and clozapine to the attention of the psychiatrist and medical specialist. Once the appropriate dosage for this patient was established, his psychotic and affective symptoms were controlled, he was not hampered by adverse side effects, and he started to actively participate in social and recreational activities and plans that culminated in discharge from a state psychiatric facility to a supportive community residence. It is our hope that the lessons we have learned from our shared experience with this patient will be of benefit to other clinicians and patients.
