Serial EEG findings in 27 cases of Creutzfeldt-Jakob disease.

Serial EEG examination was performed in a series of 27 cases of Creutzfeldt-Jakob disease observed in Chile in the period 1960 to 1977. The pattern of EEG disturbances is described in the different stages of the disease and compared with those previously reported. In the fully developed stage of the disease, 94% of the EEGs (25 of 27 patients) showed a characteristic periodic aspect. The progressive disappearance of the superficial periodic activity is tentatively explained in one patient submitted to stereo EEG.

Prevalence of epilepsy in children of Melipilla, Chile.

The prevalence of epilepsy among children born in 1966 and reaching the age of 9 years during 1975 was investigated in Melipilla, Chile, using questions similar to those used by Rose et al. (1973). Of 2,104 potential respondents, 2,085 were interviewed. A sample of 593 children received neurological examination and 455 received an electroencephalogram. The prevalence rates for epilepsy were higher than those reported in two American studies using the same methodology. The possibility of socioeconomic factors to account for these differences was considered. Prevalence rates for simple febrile convulsions and minimal brain dysfunction were similarly calculated.

Occlusive arterial disease of the child and young adult. Clinical electroencephalographical analysis of 26 cases.

26 patients suffering from acute arterial disease, predominant in childhood and young adults, have been studied. Convulsive symptom and electroencephalographic (EEG) findings are especially analyzed. The series are grouped following the Hilal classification, based on angiographical aspects. The incidence and etiological facts as well as the clinical and the angiographical findings, are summarized. The EEG analysis shows the high incidence of localized or lateralized abnormalities (23 out of 26), closely related with the clinical signs. However, there is no close relationship between these findings and the conscious state of the stage of the disease. An attempt is made to correlate the added diffuse and/or paroxysmal activities with the brain damage suspected by the angiographical signs. Seizures are present in 10 cases, 9 of them as initial symptoms predominantly of the focal type. There seems to be no relationship between the incidence and type of fits and the angiographical findings. Follow-up study shows that seizures do not modify the immediate course of the disease nor the persistence of this sequela in 9 of the controlled patients. The histopathological findings of cerebral vessel involvement are reported.

Role of fetal surveillance in diabetic pregnancies.

The role of fetal surveillance in pregnancies complicated by insulin-dependent diabetes mellitus without evidence of hypertension, microvascular disease, or fetopathy is questioned.

Prevalence of fetal heart rate decelerations in self-referred low-risk patients in the third trimester.

We tested the hypotheses that fetal heart rate decelerations are present during the third trimester in most low risk pregnant women, the prevalence of decelerations is a function of the length of time fetal heart rate monitoring occurs and their presence is not associated with an adverse prognosis. We performed a retrospective chart review of 114 self-referred low-risk pregnant patients who presented to the labor and delivery triage area of a tertiary care hospital at 26-41 weeks gestation. None required admission to the hospital. The control group consisted of patients who delivered immediately before and after the delivery of the study patient. Normal long-term variability and fetal baseline heart rate were found in all electronic fetal monitoring tracings. Accelerations were present in 91% and decelerations in 65% of patients. There was no correlation between length of time of monitoring and the incidence of decelerations. At delivery, there were no differences in birthweight, gestational age, 5-min Apgar scores or cord pH between the control and study patients. Variable decelerations were a common finding in the third trimester of low-risk pregnant patients who self referred to labor and delivery triage. They were not prognostic of an adverse perinatal outcome.

Pediatric leg length discrepancy: causes and treatments.

Leg length discrepancies have multiple causes with a number of treatment options available to accomplish a goal of equal or near equal leg lengths at skeletal maturity. The management of a deformity in the lower extremity can be a complex undertaking requiring the skill and expertise of a multidisciplinary health care team. The purpose of this article is to provide an overview of how a treatment plan is formulated after careful evaluation through ongoing assessment, diagnosis, treatment, and follow-up. The plan of care needs to fit the needs of the child and those of the family through realistic goal setting, ongoing teaching, and support.

[The effect of encephalogram bispectral index monitoring during total intravenous anesthesia with propofol in outpatient surgery].

OBJECTIVE: To assess the effect of monitoring the encephalogram bispectral index (BIS) during outpatient surgery. Outcome measures were amount of propofol administered, awakening and discharge. MATERIAL AND METHODS: Forty consecutive outpatient surgery patients were studied. The patients gave informed consent and received general intravenous anesthesia with propofol administered through a laryngeal mask using a computerized system (Diprifusor(R)). Two groups were formed: in group A, BIS was monitored, although the information was hidden from the anesthesiologists, who used the usual signs (loss of blinking reflex, pupil size and hemodynamic response) to guide anesthesia; in group B the anesthesiologists used BIS monitoring to guide propofol administration. Measurements were blood pressure, heart rate and BIS at six times during the procedure (T1-T6). Other data recorded were age, weight, height, propofol consumption in relation to weight and duration of procedure, consumption of rocuronium and alfentanil, duration of propofol infusion, time from withdrawal of propofol until eye opening, duration of stay in the post-anesthesia intensive care unit and time until total recovery. A questionnaire assessed the presence of intraoperative awareness and degree of satisfaction. The data were analyzed by Student's t and a chi square tests, with statistical significance at p < 0.05. RESULTS: Demographic variables (age, weight and height) were similar, as were duration of propofol infusion, total dose of alfentanil and rocuronium, evolution of blood pressure and heart rate. Statistically significant differences in BIS were observed at two times, T4 and T5; total propofol administered was 32.6% lower in group B; and time until eye opening was significantly shorter in group B. No significant differences were observed for time until full recovery. No instances of intraoperative awareness were reported and satisfaction was high in both groups. CONCLUSION: BIS monitoring allows for propofol titration that leads to a mean reduction of 32.6% in consumption, shortening the time until eye opening without causing intraoperative awareness or reducing patient satisfaction.
