The recommendation to position a patient having a seizure on a lateral decubitus is aimed at minimizing the risk of aspiration. The authors reviewed the database of the Epilepsy Foundation Clinic of South Florida for patients with epilepsy treated for pneumonia between May 1999 and May 2000 and patients admitted to two university telemetry units who had dislocation of the shoulder during an epileptic seizure. Over 2 months, 2 of 733 adults with intractable seizures had aspiration pneumonia after a generalized tonic clonic seizure (GTCS). Although no study has specifically addressed the problem of aspiration pneumonia in adults with GTCS, our findings suggest this problem is not common. From the two epilepsy centers, 5 of 806 patients dislocated a shoulder during a seizure. Video recordings showed that these patients were positioned in a lateral decubitus by staff while still having the convulsion. The dislocated shoulder in all cases was on the lower side. The risk of shoulder dislocation in a convulsing patient positioned in a lateral decubitus is less than 1%. Nevertheless, dislocations can result in disabling recurrences and are easily preventable. Because aspiration is more likely in the postictal rather than ictal phase of a GTCS, when oral secretions are not usually increased and there is cessation of respiratory movements, lateral decubitus should only be implemented after cessation of the convulsion, In inpatients (such as those on telemetry), secretions may be better managed by bedside aspiration of the oral cavity.

Forty-four children (20 male: 24 female) with West syndrome (infantile spasms, mental retardation/regression and hypsarrhythmia) diagnosed at Sultan Qaboos University Hospital (Pediatric Neurology Division of the Department of Child Health) are reported, with thirty-four (77.3%) children constituting the symptomatic group. All children were followed up for an initial 1 year at this hospital. Thirty-seven cases (84%) still continue their follow-up with us. The age of onset ranged from 1 to 14 months (mean, 6.0 months). Developmental delay before the onset of infantile spasms was noted in 29 (65.9%) children. Brain computed tomography was abnormal in 29 (65.9%). Sodium valproate and vigabatrin were the most often used drugs, though other antiepileptic drugs were also used. Nine (24.5%) children achieved good seizure control, out of which five have normal development. Only one child could be weaned off antiepileptic drugs completely. There was one death in the whole series, related to aspiration pneumonia.

This report may be the first case of perioperative management in a patient with dentato-rubro-pallido-luysian atrophy (DRPLA). A 19-yr-old man with DRPLA was admitted for recurrent aspiration pneumonia. Medications included phenobarbital, carbamazepine and clonazepam. The planned surgical procedure was tracheostomy and tracheoesophageal separation. He recovered from these procedures uneventfully. Two months later, however, he was readmitted for plastic surgery of narrowing tracheostoma. All of these procedures were performed under general anesthesia, induced using propofol (or thiamylal) and vecuronium, and maintained with sevoflurane. Thiamylal, propofol and benzodiazepines were effective in the prevention of myoclonus-like seizure. No adverse effects of muscle relaxant were observed.

Patients with severe neurological impairment may develop recurrent pneumonia due to aspiration. Laryngotracheal separation and tracheoesophageal diversion are one of the surgical treatments to prevent salivaly aspiration. We report anesthetic management for laryngotracheal separation and tracheoesophageal diversion of five pediatric patients with severe cerebral palsy. Anesthetic problem was that all patients was repeating intractable pneumonia. And when the trachea was resected from esophageal mucosa, we experienced temporary ventilatory disturbance. So airway management was most important during anesthesia. Perioperative complications were postanesthetic seizure and postoperative brief apnea. Recurrent fever and aspiration pneumonia subsided in all of them. Our impression is that laryngotracheal separation and tracheoesophageal diversion are not so invasive surgical treatment for intractable pneumonia. But perioperative management should be concerned about both respiratory and neurological problems.

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.

In this report, we describe the natural intoxication of 2 dogs that consumed moldy dairy products found in the household garbage and the procedures used to identify and quantify the tremorgenic mycotoxins, roquefortine and penitrem A, in the remaining portions of ingested materials. Following the ingestion of mycotoxins, the dogs of our report developed muscle tremors or seizures that resembled clinical signs of strychnine poisoning. Roquefortine was the predominant mycotoxin in a moldy cream cheese wrapper that was found among scattered garbage consumed by the first dog. Penitrem A was the only mycotoxin detected in discarded moldy macaroni and cheese that was consumed by the second dog. Treatment of dogs with tremorgenic mycotoxin intoxication involves supportive care. Close monitoring is important because the development of aspiration pneumonia is common and has been reported as the cause of death. Clinical signs of intoxication gradually resolve within 24 to 48 hours.

Long-term prognosis in dialysis is poor compared to that in healthy control persons. A worsening of the prognosis is noted especially for patients who at initiation of dialysis have congestive heart failure, ischemic heart disease, or left ventricular dysfunction or hypertrophy. This is the main reason that cardiovascular causes are the most common for morbidity in these patients. The weight obtained when normal urine output is present is the dry weight. With reduced ability to excrete the volume by the kidneys in end-stage renal disease (ESRD), the body will retain water and the patient will gain weight. This extra weight is due to volume overload. While volume overload may induce a rise in blood pressure, if the heart is in acceptable condition, a fast removal of fluid by ultrafiltration (UF) during dialysis may instead cause hypotension. Ultrafiltration failure in peritoneal dialysis (PD) patients may lead to successive water retention and overhydration with subsequent cardiac failure, while volume overload may occur over a few days in hemodialysis (HD) patients. Anemia or even too-high hematocrit may impair cardiac function further and worsen conditions caused by wrong dry weight. Thus, during long-term and sustained volume overload, left ventricular (LV) hypertrophy will occur in an eccentric manner. A sustained overload then may lead to cell death and LV dilatation and, eventually, systolic dysfunction. Once a severe left ventricular dilatation has developed, the blood pressure may decrease during volume overload. A worsened prognosis is seen if malnutrition and low albumin levels are present. Volume overload necessitates ultrafiltration to achieve dry weight. Thereby, volume contraction contributes to exaggerated stimulation of or response to activation of the RAS and alpha-adrenergic sympathetic systems. If ultrafiltration goes beyond these compensatory mechanisms, hypotension will occur and increase the risk for hypoperfusion of vital organs. Such episodes may cause cardiac morbidity, aspiration pneumonia, vascular access closure, or neurological complications (seizures, cerebral infarction), besides a more rapid lowering of residual renal function. Preventive measures are, first, finding the right dry weight; second, minimizing interdialytic weight gain; third, optimizing the target for hemoglobin (110-120 g/l); fourth, lowering dialysate calcium (1.25 mmol/l); and fifth, eventually using higher dialysate potassium if long dialyses are performed.

We reviewed the incidence of aspiration pneumonia secondary to seizures in three populations of patients with chronic epilepsy: 733 outpatients seen in an Epilepsy Foundation clinic; 806 adult patients admitted to two university video telemetry units; and 95 institutionalized, profoundly retarded adult patients with chronic epilepsy. Two of the 733 adults who had seizures in the outpatient setting and 2 of the 806 patients who had one or more epileptic seizures in the telemetry units developed aspiration pneumonia. In the 95 institutionalized patients, there were 17 instances of aspiration pneumonia after a generalized seizure and 32 instances of aspiration unrelated to seizures over a 12-month period. Our findings suggest that aspiration pneumonia is not a common complication of seizures in otherwise healthy adults. The increased incidence of aspiration in developmentally delayed individuals seems to derive from a combination of factors. Increased oral secretions, impaired swallowing mechanisms, and difficulty in attaining adequate patient positioning significantly increased the risk of aspiration.

Decisions on ventilatory support (VS) in multiple sclerosis (MS) are complex. All patients with MS requiring mechanical ventilation or tracheostomy since 1969 (22) at Mayo Clinic were reviewed. Seventeen had progressive (PMS; 11 secondary and six primary progressive) and one had relapsing remitting MS (RRMS). Four had neuromyelitis optica (NMO). Of those with PMS, all but two required a wheelchair or were bedbound before VS and survived a median of 22 months; 14 were mechanically ventilated and seven underwent subsequent lifelong tracheostomy; three had tracheostomy only. The indications (usually multiple) for VS in PMS patients were aspiration pneumonia, poor ventilation because of mucous plugging, mechanical failure, and airway control/protection for seizures and coma. The RRMS patient required mechanical ventilation for 10 days, with subsequent short-term tracheostomy during a brainstem exacerbation. Of the four patients with NMO one made a dramatic recovery after plasmapheresis. Compared with PMS, the NMO group had a shorter time from disease onset to VS, a longer duration of ventilation, and the three patients not treated with plasma exchange or steroids did worse. The prognosis for independent ventilation (+/- tracheostomy) was worst for patients with NMO, except for one patient who received plasma exchange, and better then expected for PMS, despite poor preventilation functional status.

Delirium is one of the most common disorders in hospitalized patients. The authors present the case of an elderly male patient with postoperative cognitive decline that did not resolve with the conventional treatment. The diagnosis was only established on autopsy. A 75-year-old man was evaluated after a fall. Initial evaluation revealed voluntary guarding in the right epigastric region, and free air was detected under the right hemidiaphragm on abdominal radiography. An exploratory laparotomy revealed a perforation that had apparently sealed off. After surgery, he had initial improvement toward baseline; however, after several days, his postoperative course was complicated by a progressive deterioration in mental status, recurrent seizures, and aspiration pneumonia. Computed tomographic scan of the brain showed communicating hydrocephalus. Examination of the cerebrospinal fluid revealed an elevated opening pressure and elevated protein. His mental status continued to deteriorate, and he died. Autopsy revealed the pathologic diagnosis of primary leptomeningeal melanomatosis.
