Objective

To investigate the predictive index of functional recovery after primary pontine hemorrhage (PPH) using the combined motor evoked potential (MEP) and somatosensory evoked potential (SEP) in comparison to the hematoma volume and transverse diameter measured with computerized tomography.

Methods

Patients (n=14) with PPH were divided into good- and poor-outcome groups according to the modified Rankin Score (mRS). We evaluated clinical manifestations, radiological characteristics, and the combined MEP and SEP responses. The summed MEP and SEP (EP sum) was compared to the hematoma volume and transverse diameter predictive index of global disability, gait ability, and trunk stability in sitting posture.

Results

All measures of functional status and radiological parameters of the good-outcome group were significantly better than those of the poor-outcome group. The EP sum showed the highest value for the mRS and functional ambulatory category, and transverse diameter showed the highest value for "sitting-unsupported" of Berg Balance Scale.

Conclusion

The combined MEP and SEP is a reliable and useful tool for functional recovery after PPH.

Case Report

Case Reports of Peduncular Hallucinosis in Patients with Pontine Hemorrhage : Two cases report.: Shin, Oh Soo , Kim, Tae Gun , Kwon, Soon Mo , Park, Dong Hwi , Byun, Seung Deuk; J Korean Acad Rehabil Med 2009;33(3):365-368.

Abstract
PDF

Peduncular hallucinosis that rarely reported in patients with brain stem lesion has several characteristics. The hallucination tends to be vivid, nonstereotypical images of person or animal. All the patients are aware that the hallucination is not part of reality. One of the suggested mechanisms of peduncular hallucinosis is imbalance among the cholinergic, serotonergic and other transmitting systems in the brain stem. We report two cases with typical features of peduncular hallucinosis which appeared about 30 and 12 months after pontine hemorrhage, respectively. We chose antipsychotics and selective serotonergic reuptake inhibitors for their medications, and their hallucinations disappeared about 2 months and 3 weeks after the medication, respectively. We suggest that peduncular hallucinosis should be considered in the patients with pontine hemorrhage if they complain of typical visual hallucinations. (J Korean Acad Rehab Med 2009; 33: 365-368)
