Forty patients with cranial bone defects after craniectomy underwent extensive cerebrospinal fluid (CSF) hydrodynamic investigations by means of a CSF infusion test before and after cranioplasty. The results of these investigations were related to the clinical signs of the patients before and after cranioplasty and to the size and location of the skull bone defect. Twenty-two patients were considered to have "the syndrome of the trephined" (ST). The remaining patients were either free of symptoms or had symptoms not related to ST. CSF hydrodynamic variables that were changed before and normalized after cranioplasty include the following: Resting pressure, sagittal sinus pressure, buffer volume, elastance at resting pressure and pulse variations at resting pressure. The changes were statistically significant mainly in ST patients who were also relieved of their symptoms after cranioplasty.
Familial amyloidotic polyneuropathy (FAP) is an autosomal dominant inherited disorder characterized by progressive peripheral and autonomic neuropathy, associated with neural and systemic amyloid deposits. The amyloid fibrils contain a variant transthyretin (TTR) molecule (TTR met30), over 90% of which is produced in the liver. After liver transplantation in two patients with severe symptomatic FAP, only normal TTR was detectable in circulation. The two patients are being monitored at regular intervals, and, although in one patient there was no evidence of reduction in the quantity of amyloid present at 6 months, there had been no further progression of the neuropathy.
SUMMARY With the patient in the supine position, the subarachnoidal space was infused with artificial CSF at several constant pressure levels. The resulting flow of liquid was recorded.
Summary: Purpose: To study the incidence of epilepsy in a rural area of Ethiopia.Methods: A community-based study was performed in a random sample of villages with 61,686 inhabitants in a rural area of central Ethiopia. In a door-to-door survey, all inhabitants in the study area were interviewed about seizures. A standardized protocol was used. All new cases with epilepsy that had occurred since a previous study was made 3.5 years earlier were included. Fifty-three of the subjects were investigated with EEG.Results: One-hundred thirty-nine incident cases were identified, corresponding to an annual incidence of 64 in 100,000 inhabitants [95% confidence interval (CI) 44-84]. The corresponding rate for males was 72 (CI 42-102); for females, it was 57 (CI 31-84). The highest age-specific incidence occurred in the youngest age groups (0-9 years); the next highest was in the group aged 10-19 years. Generalized convulsive seizures occurred in 69%, partial seizures ~ ~~ ~~ occurred in 20%, and unclassifiable seizures occurred in 11%. Seizures occurred daily in 10% and weekly in another 14%; 33% had monthly seizures. Twenty-two percent had a family history of epilepsy. A history of head trauma was ascertained in 5.7% and was the most common possible etiologic factor identified. Thirteen percent were treated with antiepileptic drugs (AEDs).
Conclusions:The incidence of epilepsy in Ethiopia is high. A high incidence in combination with a prevalence of epilepsy in the study area comparable to that in the rest of the world may be explained by a high degree of spontaneous remission of epilepsy and/or a high mortality due to epilepsy. Despite health education on epilepsy given to the community, a minority of subjects were treated with AEDs, which may reflect the inadequacies of the health services and transportation difficulties faced by the patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
