Chronic hypoxemia is known to cause peripheral neuropathy (PNP) in chronic obstructive pulmonary disease (COPD) patients. We aimed to know how often PNP is encountered in such patients and the changes in the central nervous system (CNS) if any. We enrolled 32 patients (30 M, 2 F; mean age +/- SD: 61.5 +/- 8.8 years) with COPD into the study. PaO2 > or = 55 mmHg was considered as the cut-off val...

Brainstem auditory evoked response (BAER) is a reliable test for neonatal auditory and neurological dysfunction and it permits early diagnosis and rehabilitation. The purpose of this study is to demonstrate latencies of BAER in normal term neonates in order to obtain reference values in a university hospital. BAER was performed in the second day of life in 47 normal newborns (25 male, 22 female...

Brainstem auditory evoked responses (BAER) were longitudinally recorded prospectively in 18 term infants with neonatal hyperbilirubinemia (NHB) (total serum bilirubin > 15 mg/dl). Seven neonates had abnormal BAER. Wave complex IV-V was absent in eight recordings in NHB group while they were normal in the control group (p < 0.001). Prolongation of latency of waves I and V and interwave conductio...

BACKGROUND Brainstem auditory evoked response has been an underused diagnostic modality in horses as evidenced by few reports on the subject. HYPOTHESIS/OBJECTIVES To describe BAER findings, common clinical signs, and causes of hearing loss in adult horses. ANIMALS Study group, 76 horses; control group, 8 horses. METHODS Retrospective. BAER records from the Clinical Neurophysiology Labora...
