To evaluate the changes of ABR values in hyperbilirubinemic newborns, 85 cases with severe jaundice (total bilirubin levels over 16 mg/dL and direct bilirubin less than 2 mg/dL) were selected from those admitted to Children's Medical Center by simple sampling method. These infants had no other problem except jaundice. ABR was taken before treatment in all cases and in some (10 cases) after...

in an attempt to assess objectively the integrity of the auditory pathways in 30 patients with definite multiple sclerosis (ms), an audiometric evaluation was performed and auditory brainstem responses (abrs) were obtained. stressing the auditory system by increasing the stimulation rate showed some enhancement in the identification of ms. 24 (ro%) patients had an abnormal abr along with clinic...

Changes in brainstem auditory-evoked potential response were serially investigated in 20 head-injury patients with neurologic and computed tomographic signs of brainstem lesion. The reliability of computed tomography in the evaluation of indirect signs of brainstem lesion from the image was investigated with elaboration of the brainstem auditory-evoked potential response. The measurement of aud...

Neuropathological and neuroimaging studies show cortical and subcortical volume loss in alcohol-dependent individuals. Using quantitative magnetic resonance imaging (MRI) and proton magnetic resonance spectroscopic imaging ((1)H MRSI), we studied the size and potential cellular injury of the brainstem in untreated heavy alcohol drinkers. The brainstem is considered critical in the development a...

A 65-year-old comatose man with metastatic melanoma developed rapidly cycling breathing, clusters of approximately 10 abdominal excursions within 3 seconds, interspersed by seconds apnea (video 1 and figure), mimicking myoclonus. Introduced Plum Posner1 as a respiratory pattern associated lesions in the low pons or high medulla, cluster breathing can occur without pontomedullary when alkalosis ...

introduction: neonatal hypernatremia dehydration (nhd) is a dangerous condition in neonates, which is accompanied by acute complications (renal failure, cerebral edema, and cerebral hemorrhage) and chronic complications (developmental delay). children begin learning language from birth, and hearing impairment interferes with this process. we assessed the hearing status of infants with hypernatr...

while most tinnitus cases have some degree of hearing impairment, a small percent of the patients admitted to ear, nose and throat clinics or hearing evaluation centers are those who complain of tinnitus despite having normal hearing thresholds. present study was performed in order to better understanding of the probable causes of tinnitus and to investigate possible changes in the cochlear and...

background: brainstem hemorrhage was first described by cheyne in 1812 in a pathological study of patients presenting with lethargy and coma. in 1877 bode reviewed the findings of 67 patients reported in the literature (1). in the united states, the incidence of closed head injury is estimated to be approximately 200 cases per 100,000 persons per year. the financial burden of head injuries in t...

Brainstem death and brain death although practically same with regards to the concept of organ donation, remain technically different. Brain death mandates irreversible cessation of all the functions of the entire brain and brainstem while brainstem death signifies irreversible damage to the brainstem. As per the Indian law, brainstem death is the legal requirement and not brain death.

Cortical spreading depression is a pathophysiological excitation wave that occurs during pathophysiological brain conditions such as ischemic brain infarction, migraine aura, and others. Judged from experiments in rodents, the brainstem is thought to be comparatively resistant to the generation of spreading depression. However, because spreading depression can be elicited in the brainstem of ra...
