Intramedullary Spinal Schwannoma: Case Report and Review of Preoperative Magnetic Resonance Imaging Features

Intramedullary schwannomas are rare spinal cord tumours. Correct preoperative diagnosis is essential for proper surgical planning and complete resection. We present a case of cervical intramedullary schwannoma followed by discussion on its preoperative magnetic resonance imaging features and review of the literature

Amorphane sesquiterpenoids from the liverwort Marsupella emarginata var. aquatica

Four oxygenated amorphane derivatives [(-)-(1R,2S,6R,10S)- 2alpha-acetoxyamorpha-4,7(11)-dien-8-one, (-)-(1R,2S,6R,10S)- 2alpha-acetoxy-11-methoxyamorpha-4,7-diene, (-)- (1R,2R,3S,6R,10S)-2alpha,3alpha-diacetoxyamorpha-4,7(11)-dien- 8-one and (-)-(1R,2R,3R,6R,9S,10R)2alpha,3alpha-diacetoxy- 9alpha-hydroxyamorpha-4,7(11)-dien-8-one] have been isolated from the Scottish liverwort Marsupella emarginata var. aquatica. Their structures were determined following extensive (mainly 1D and 2D NMR) spectroscopic studies

Monitoring Vital Signs With Time-Compressed Speech

Spearcons-time-compressed speech phrases-may be an effective way of communicating vital signs to clinicians without disturbing patients and their families. Four experiments tested the effectiveness of spearcons for conveying oxygen saturation (SpO ) and heart rate (HR) of one or more patients. Experiment 1 demonstrated that spearcons were more effective than earcons (abstract auditory motifs) at conveying clinical ranges. Experiment 2 demonstrated that casual listeners could not learn to decipher the spearcons whereas listeners told the exact vocabulary could. Experiment 3 demonstrated that participants could interpret sequences of sounds representing multiple patients better with spearcons than with pitch-based earcons, especially when tones replaced the spearcons for normal patients. Experiment 4 compared multiple-patient monitoring of two vital signs with either spearcons, a visual display showing SpO and HR in the same temporal sequence as the spearcons, or a visual display showing multiple patient levels simultaneously. All displays conveyed which patients were abnormal with high accuracy. Visual displays better conveyed the vital sign levels for each patient, but cannot be used eyes-free. All displays showed accuracy decrements with working memory load. Spearcons may be viable for single and multiple patient monitoring. Further research should test spearcons with more vital signs, during multitasking, and longitudinally
