Even with the best health care available, many patients with epilepsy still suffer from poorly controlled seizures. Patients with intractable partial seizures are often inhibited from realizing their full potential and may experience a less than optimal quality of life. Vagus nerve stimulation (VNS) is being studied in a double-blind, controlled, randomized trial at 17 epilepsy centers throughout the U.S. and Europe as a potential therapy for patients with refractory seizures. During a 14-week controlled phase in three of the centers, the therapeutic group (N = 10) experienced a mean seizure frequency percent reduction (SFPR) of 33.1% as compared to baseline (p = 0.0084) while the subtherapeutic group (N = 12) experienced an SFPR of 0.6% as compared to baseline (p = 0.9183). After the controlled phase, all patients were switched into the therapeutic group in an open extension phase. Results after one year of therapeutic stimulation (N = 15) reveal a mean SFPR of 35.6% (p = 0.0088) with 6 of the 15 patients (40%) achieving at least a 50% seizure reduction. Adverse effects included hoarseness, coughing and nausea. There were no deaths or serious injuries related to the device. Based on these limited data, VNS appears to be a safe and efficacious new therapy for refractory partial seizures.

Aspiration is the leading cause of anaerobic lung infections. Risk factors for these infections include a depressed level of consciousness, a history of seizure, general anesthesia, central nervous system or neuromuscular disease, cerebrovascular accident, impaired swallowing and use of a tracheal or nasogastric tube. Clinical presentation includes fever, weight loss, malaise and cough productive of foul-smelling sputum. Diagnosis is based on radiographic findings, clinical features and a characteristic morphology of mixed flora on Gram stain of uncontaminated pulmonary specimens. The diagnosis is confirmed by isolation of organisms, usually polymicrobial, on culture. Treatment includes proper drainage, debridement of necrotic tissue and an antibiotic regimen (often initially empiric) with an agent active against anaerobic and aerobic organisms.

Cocaine abuse surged in the 1980s, forcing reevaluation of its previously benign image. Snorted, smoked, and injected, the drug is more widely abused than ever and, the consequences are devastating. Medical complications are frequent and range from mild (eg, cough, itching, headache) to life-threatening (eg. stroke, seizure, cardiovascular failure). Behavioral disturbances constitute the most dramatic and widespread effects of intoxication and withdrawal. Psychopathologic responses may include perceptual disturbances (eg. hallucinations) agitation, aggression, delirium, confusion, and profound delusional ideation. The goals of treatment are abstinence, rehabilitation, and relapse prevention. Hospital care may be necessary in certain circumstances. Regardless of where treatment takes place, a comprehensive program of supportive care, behavioral therapy, urine monitoring, and often psychopharmacologic intervention is required.

This case presentation will discuss the pathophysiology of a child in septic shock due to Neisseria meningitidis. The most prevalent nursing care concerns of this case encountered during the pediatric intensive care unit (PICU) and during the general floor stay will be addressed. The nursing skill required for identifying problems and planning care that clearly fall under the nursing domain also will be covered. In addition, the complexities of this case demonstrate that collaboration between the PICU nurse and the general pediatric nurse is imperative for successful patient outcome. A.W. was a 5 1/2-month-old infant transported to our PICU from a referral hospital in the state. Diagnosis at time of admission was meningococcemia, disseminated intravascular coagulopathy, septic shock, respiratory failure, and purpura fulminans. There was a 2- to 3-day history of a runny nose, cough, and vomiting. On the day of admission, A.W. had three seizures and developed a fever and a purpuric rash.

Lidocaine-induced seizures have been reported after topical administration. A 30-year-old, 48-kg women with acquired immunodeficiency syndrome, chronic end-stage renal failure, anemia, congestive heart failure (CHF), cardiomyopathy, and increased liver function tests was admitted to the hospital with fever, chills, and dry cough. Bronchoscopy was performed to rule out Pneumocystis carinii pneumonitis; the patient experienced seizure activity after administration of a total dose of topical lidocaine 300 mg. Plasma drug concentration measured shortly after seizure, and at 4 and 22 hours after seizure were 12.0, 7.6, and 1.4 mg/L, respectively. A direct correlation exists between clinical symptoms and blood level of lidocaine; as the level increases to 8-12 mg/L the probability of seizure increases. The extent of absorption and bioavailability after airway administration depends on tissue vascularity, sites and techniques of application, patient's disease state, and, most important, the dose/unit body weight. The lidocaine dose should be titrated slowly and patients monitored for altered mental status. The dose often has to be decreased empirically in patients with liver disease or CHF. Efforts should be made to deliver minimum amounts of the drug to the lower respiratory tract, since its pharmacokinetics at that site are similar to those with intravenous administration.

A five year retrospective review of all exposures to a high concentration phenol disinfectant (Creolin Disinfectant 26% phenol) reported to a regional poison center located 96 cases, with 16 cases lost to follow up. There were 60 oral-only exposures, 7 dermal-only exposures and 12 oral/dermal exposure. One patient was an inhalation exposure. Fifty-two cases (65%) were evaluated in a hospital. Eleven patients with oral exposures (14%) experienced rapid CNS depression, but no seizures occurred. Vomiting, coughing, and stridor was noted in 14, 7 and 4 patients respectively. Burns were noted in 17 of 72 (24%) patients with oral exposure and 5 of 19 (26%) with dermal exposure. Seventeen patients underwent endoscopy. Tissue sloughing was noted in one case. All other burns were first degree. No cardiovascular complications occurred. Twenty-eight patients (35%) were followed at home via telephone with one episode of vomiting and one episode of dermal irritation occurring. CNS toxicity from exposure to a high concentration phenol containing cleaning product appears to be rapid in onset. The absence of serious toxicity and major chemical burns in this series does not eliminate concern with the corrosive and systemic risks of phenol poisoning.

The rural CGW population has not yet undergone the metamorphosis experienced by its urban counterparts. Reminiscent of a past era, suicides far outweight homicides. Although many rural firearm injuries involve hunting accidents, these comprise only a small fraction of CGW at best. Similarly, although many rural firearm injuries involve shotguns or rifles, few CGW result from these weapons. Although the number of patients is small, those with shotgun or rifle injuries manifest lower mortality rates. The authors have confirmed the notion that caliber of civilian weapons is difficult to correlate with outcome. The geographic size of the rural catchment area is an important consideration because it must select a population able to withstand transfer. The authors noted an inverse relationship between length of time before arrival at the facility and mortality. The selection phenomenon probably accounts for the reduced mortality found in the authors series versus most others. Prognostic features of individual gunshot wounds are likely to be similar among varied populations when circumstances of the injury are matched. Thus, one expects similar features on initial examination and CT scan to have similar predictive value. The authors confirmed that CGS and specific deficits were strong predictors of outcome. No patient with a GCS score of 5 or less on admission survived. Absent pupillary response, absent brain stem function, presence of respiratory drive or cough only, and posturing were strong indicators of impending death. The authors confirmed the prognostic value associated with CT evidence of intraventricular hemorrhage, transventricular trajectory, transtentorial herniation, massive edema, and bihemispheric injury. Interestingly, presence of extensive facial fractures, an indicator of trajectory, suggested better outcome. Subarachnoid hemorrhage did not reach prognostic significance. Roughly half of the authors' patients had positive serum ethanol levels, although the test was unable to discern prognosis. Abnormality of any coagulation parameter and frank disseminated intravascular coagulation were correlated with poor outcome. Likewise, thrombocytopenia occurring within the first 24 hours was an indicator of poor prognosis. Although prophylactic antibiotics were not used in all cases, the authors encountered no deep or superficial infections in surviving patients. The prevalence of seizures in the authors' series despite prophylactic AED is unusually high. This feature merits further study.

We have analysed retrospectively the clinical features and electroencephalograms in 35 patients with complex partial seizures of temporal lobe origin who were seizure-free after epilepsy surgery. Two groups were differentiated for statistical analysis: 16 patients had hippocampal temporal lobe seizures (HTS) and 19 patients had extrahippocampal temporal lobe seizures (ETS) associated with a small tumour of the lateral or inferior temporal cortex. All patients in the HTS group had ictal onset verified with intracranial recordings (depth or subdural electrodes). In the ETS group, extrahippocampal onset was verified with intracranial recordings in eight patients and assumed, because of failure of a previous amygdalohippocampectomy, in one patient. Historical information, ictal semiology and ictal EEG of typical seizures were analysed in each patient. The occurrence of early and late oral automatisms and dystonic posturing of an upper extremity was analysed separately. A prior history of febrile convulsions was obtained in 13 HTS patients (81.3%) but in none with ETS (P < 0.0001, Fisher's exact test). An epigastric aura preceded seizures in five patients with HTS (31.3%) and none with ETS (P = 0.0135, Fisher's exact test), while an aura with experiential content was recalled by nine patients with ETS (47.4%) and none with HTS (P = 0.0015), Fisher's exact test). Early oral automatisms occurred in 11 patients with HTS (68.8%) and in two with ETS (10.5%) (P = 0.0005, Fisher's exact test). Early motor involvement of the contralateral upper extremity without oral automatisms occurred in three patients with HTS (18.8%) and in 10 with ETS (52.6%) (P = 0.0298, Fisher's exact test). Arrest reaction, vocalization, speech, facial grimace, postictal cough, late oral automatisms and late motor involvement of the contralateral arm and hand occurred with similar frequency in both groups. These observations show that the early clinical features of HTS and ETS are different.

The present paper describes eight patients (two teenagers and six adults) who had chronic symptoms (haemoptysis, cough, recurrent pneumonia) caused by foreign body (FB) inhalation which went undetected for 3 months to 25 yr. None of the patients had the usual predisposing conditions like mental retardation, seizures or brain tumour. The diagnosis of FB was made by radiography in one patient only. Computerized tomography visualized one FB (a beef bone), and bronchoscopy identified FB in another two patients. The remaining four cases were diagnosed at thoracotomy. Removal of FB was curative in three of five cases who required surgical resection for irreversible bronchiectatic changes. The severity of pulmonary changes correlated with duration of symptoms. It is concluded that chronic, unexplained respiratory symptoms should warrant further investigation to exclude FB despite negative history and normal chest radiography. Finding of granulation tissue or cicatricial stenosis of the bronchus could be the only clue to the presence of a FB. Early diagnosis would avoid irreversible parenchymal changes which necessitate lung resection.
