Abstract

Background In accordance with German neurosurgical and neurological consensus recommendations, lead placements for deep brain stimulation (DBS) in patients with Parkinson’s disease (PD) are usually performed with the patient awake and in “medication off” state. This allows for optimal lead position adjustment according to the clinical response to intraoperative test stimulation. However, exacerbation of Parkinsonian symptoms after withdrawal of dopaminergic medication may endanger the patient by inducing severe “off” state motor phenomena. In particular, this can be a problem in awake craniotomies utilizing intraoperative airway management and resuscitation. Case presentation We report the case of a PD patient with progressive orofacial and neck muscle dystonia resulting in laryngeal spasm during DBS lead placement. This led to upper airway compromise and asphyxia, requiring resuscitation. Conclusions Laryngeal spasms may occur as a rare “off” state motor complication in patients with PD. Other potential causes of intraoperative difficulties breathing include bilateral vocal cord palsy, positional asphyxia, and silent aspiration. In our practice, we have adjusted our medication regimen and now allow patients to receive their standard dopaminergic medication until the morning of surgery. Neurologists and neurosurgeons performing lead placement procedures for PD should be aware of this rare but unsafe condition to most optimized treatment. peerReviewed

19. Synovial Cyst Mimicking an Intraspinal Sacral Mass

Abstract

A 68-year-old female had a three-week history of severe low back pain radiating down the posterior left buttocks and left leg exacerbated by standing and walking. Lumbar spine MRI revealed cystic mass with similar intensity to cerebrospinal fluid located on dorsolateral left side of the sacral spinal canal inferior to the S1 pedicle. There was compression of left exiting S1 and traversing S2 nerve roots. Neurosurgery consult was requested to evaluate the cystic mass in the sacral spinal canal. After clinical evaluation, an unusually located synovial cyst was thought possible. Cyst contents were heterogeneous, suggestive of small hemorrhage and acute clinical history seemed reasonable. Left S1 and partial left S2 hemilaminectomy was performed and an epidural, partially hemorrhagic cyst was removed. There was no obvious connection to the ipsilateral L5-S1 facet joint. Pathology revealed synovial cyst, and the patient’s leg pain was improved postoperatively. This synovial cyst was unusual as it had no connection with the facet joint intraoperatively and its location in the sacral canal was uncommon.

45. Use of preoperative magnetic resonance imaging T1 and T2 sequences to determine intraoperative meningioma consistency.

Author

Hoover, Jason M., Morris, Jonathan M., and Meyer, Fredric B.

Abstract

Background: Meningioma firmness is a critical factor that influences ease of resection and risk, notably when operating on tumors intimate with neurovascular structures such as the mesial sphenoid wing. This study develops a predictive tool using preoperative magnetic resonance imaging (MRI) characteristics to determine meningioma consistency. Methods: 101 patients with intracranial meningioma (50 soft/51 firm) were included. MRI characteristics of 38 tumors (19 soft/19 firm) were retrospectively reviewed to identify preoperative imaging features that were then correlated with intraoperative description of the tumor as either “soft and/or suckable” or “firm and/or fibrous.” Criteria were developed to predict consistency and then blindly applied to the remaining 63 meningiomas (31 soft/32 firm). Results: The overall sensitivities for detecting soft and firm consistency were 90% and 56%, respectively (95% CI = 73–97% and 38–73%; P < 0.001). Compared to gray matter, meningiomas that were T2 hypointense were almost always firm. Soft meningiomas were hyperintense on T2 and hypointense on T1. Soft meningiomas were slightly larger and less likely to be associated with edema. There was a slight preponderance of firm meningiomas in the infratentorial compartment. Grade of meningioma was not predictive. Contrast enhancement, diffusion restriction, changes in overlying bone, intratumoral cysts, and angiographic features were not predictable. Conclusions: This tool using T1 and T2 series predicts meningioma consistency. Such knowledge should assist the surgeon in preoperative planning and counseling. [ABSTRACT FROM AUTHOR]

Abstract

Objective: To test the hypothesis that norepinephrine induces a pressor response in the pulmonary vascular bed of the cat and identify the alpha-(1)adrenoceptor subtypes involved in the mediation or modulation of these effects.Design: Prospective vehicle controlled study.Setting: University research laboratory.Subjects: Intact chest preparation, adult mongrel cats.Interventions: In separate experiments, the effects of 5-methyl-urapidil, a selective alpha-(1)A-subtype adrenoceptor antagonist, chloroethylclonidine, an alpha-(1)B-subtype and -(1)D-subtype adrenoceptor antagonist, and BMY 7378, the selective alpha-(1)D-subtype adrenoceptor antagonist, were investigated on pulmonary arterial responses to norepinephrine and other agonists in the pulmonary vascular bed of the cat.Measurements and Main Results: The systemic pressure and lobar arterial perfusion pressure were continuously monitored, electronically averaged, and permanently recorded. In the feline pulmonary vascular bed of the isolated left lower lobe, norepinephrine induced a dose-dependent vasoconstrictor response that was not significantly altered after administration of BMY 7378. However, the responses to norepinephrine were significantly attenuated following administration of 5-methyl-urapidil and chloroethylclonidine.Conclusions: The results of the present study suggest that norepinephrine has potent vasopressor activity in the pulmonary vascular bed of the cat and that this response may be mediated or modulated by both alpha-(1)A-subtype and -(1)B-subtype adrenoceptor sensitive pathways.

Abstract

The article focuses on how Siemens Renewable Power Generation, a Midwestern U.S. biomass gasification power plant, won a project through Integrated Drive Systems, provider of automation systems. It details how it was able to show a plant developer how to cut 3.5 from 85 million dollars in upfront capital costs, or 4.1% of the entire project, improve the annual profit margin from 11.5% to 14.41% by delivering labor, operational and maintenance efficiencies.
