CT Angiography as a Confirmatory Test in Brain Death
2012
Objective: From recent studies, it remains unclear whether CT angiography could be an alternative to other established ancillary tests for the diagnosis of brain death. We examined intracranial contrast enhancement in CT angiography after clinically established brain death and compared the results with EEG and TCD findings.
White cord syndrome after non-contiguous double-level anterior cervical decompression and fusion (ACDF): A “no reflow phenomenon”?
2017
Abstract Study design Case report and review of literature. Objective To report a rare complication of anterior cervical decompression and fusion (ACDF) in a patient with severe cervical cord compression and review of relevant literature. Introduction The white cord syndrome is a very rare condition characterized by an ischemic-edematous lesion of the spinal cord following a surgical procedure, lacking intra o perioperative surgical or anesthesiological complications. Case report A 64-years old male affected by a severe cervical stenosis at multiple levels, with voluminous C3–C4 and C5–C6 disc herniations associated to T2-hyperintense myelomalacic area at C3–C4 level was admitted to our Uni…
Stroke Care Within the COVID-19 Pandemic—Increasing Awareness of Transient and Mild Stroke Symptoms Needed
2020
Background: The COVID-19 pandemic might affect health care resources and alter patient admission to hospital in case of stroke or transient ischemic attack (TIA). We aim to determine whether the COVID-19 pandemic is affecting utilization of recanalization procedures and numbers of patients with stroke and TIA admitted to a primary care stroke center.Methods: In this retrospective observational study, we compared patients admitted from January 2019 until February 2020 with patients admitted during the COVID-19 pandemic (March/April 2020) in Germany. We included patients with stroke (hemorrhagic or ischemic) or TIA as classified by International Statistical Classification of Diseases and Rela…
Oral myiasis in a cerebral palsy patient: A case report
2010
Myiasis is a rare condition caused by the invasion of tissues by the larvae of flies, mainly from the order of Diptera. Many cases of myiasis involving various human organs have been reported. Oral Myiasis is very rare in healthy persons. It occurs mainly in the tropics and is usually associated with inadequate personal and public hygiene; sometimes accompanied by poor manual dexterity. We present a case of oral myiasis in a mentally retarded, 13- year-old boy suffering with cerebral palsy. The diagnosis was based on the characteristic clinical features and the visualization of wriggling larvae. Large numbers of larvae were found in the gingival sulcus. Treatment consisted of manual removal…
Effects of ovariectomy and steroid replacement on GABAA receptor binding in female rat brain.
1991
Abstract The specific binding of tritiated muscimol to γ-aminobutyric acid (GABA) receptor sites was studied in distinct brain areas of female rats during different endocrine states. In diestrous rats with intact ovaries the highest receptor densities were found in the cortex (10.24 pmol/mg protein) and the lowest concentrations in the mediobasal hypothalamus (3.29 pmol/mg protein). Four weeks after removal of the ovaries, the number of binding sites was enhanced up to 2.4-fold in all brain areas investigated: the preoptic brain area, mediobasal hypothalamus, corticomedial amygdala, and cerebral cortex. The affinity of the binding sites remained unchanged. Substitution of estradiol and prog…
Effects of endothelin-1 on the cerebrovascular bed of the goat.
1991
Abstract The aim of the present study was to analyze the effects of endothelin-1 (ET-1) in the cerebrovascular bed of the goat, the importance of endothelial integrity and the contribution of extracellular Ca2+ to these responses. We measured isometric tension and 45Ca2+ uptake in isolated middle cerebral arteries, and cerebral blood flow (CBF) in unanesthetized animals. ET-1 elicited concentration-dependent contractions which were potentiated in arteries without endothelium. Ca2+-free medium and nicardipine inhibited, and Bay K 8644 potentiated the ET-1-induced contractions. ET-1 enhanced 45Ca2+ uptake in isolated arteries. Injections of ET-1 directly into the cerebral circulation decrease…
Epidemiology and Classification of Strokes
1991
Epidemiology concerns the occurrence and distribution of diseases in the population. By prevalence is meant the number of cases of the disease at a particular moment in a given group of persons, for example, in the entire population of a certain territory or in a clearly demarcated population group. Incidence refers to the number of new cases of the disease occurring in a population in a particular period of time. Figures on prevalence and incidence are meaningful only if the given disease is unequivocally defined. If the definition is too specific, many cases are not included (false-negative cases), whereas too broad a definition leads to many false-positive identifications (Table 3.1). Di…

Functional brain imaging: a window into the visuo-vestibular systems
2007
Advances have been made in identifying how areas involved in processing vestibular, ocular motor, and visual information are represented in the human cortex as well as the cortical interaction between these systems in healthy subjects.While we know how some vestibular and ocular motor disorders modify visuo-vestibular interaction by changing the 'normal' cortical activation-deactivation patterns, it is still early days in functional magnetic resonance imaging studies of patients with specific disorders. Findings from current brain imaging studies of several vestibular, ocular motor, and cerebellar disorders are presented.The promise of more insights into the complex neuronal networks of the…
