Investigation of therapeutic effects of calcium dobesilate in cerebral hypoxia/ reperfusion injury in rats
CONCLUSION: From these results, it was observed that CD treatment could reduce neuronal necrosis and create anti-inflammatory, anti-edema, anti-oxidant, anti-apoptotic, and anti-autophagic effects in hypoxia/reperfusion injury in rats.PMID:36548871 | DOI:10.1080/01616412.2022.2159109

Malignant Hyperthermia: A Killer If Ignored
J Perianesth Nurs. 2022 Apr 9:S1089-9472(21)00353-1. doi: 10.1016/j.jopan.2021.08.018. Online ahead of print.ABSTRACTMalignant hypothermia (MH) is a potentially fatal hypermetabolic reaction of skeletal muscle. It is an autosomal dominant disorder that generally occurs in people with RYR1, CACNA1S, or STAC3 mutations. And these genetic abnormalities often cause the imperfection of calcium release channels of skeletal muscle. The incidence of MH among different racial groups across the world ranges from approximately 1:5,000-1:250,000, but there is no national statistic MH incidence in China. It is not clear whether there a...

Postoperative malignant hyperthermia confirmed by calcium-induced calcium release rate after breast cancer surgery, in which prompt recognition and immediate dantrolene administration were life-saving: a case report
ConclusionsThe occurrence of MH can be life-threatening, but its frequency is very low, and genetic testing and muscle biopsy are required to confirm the diagnosis. On retrospective evaluation using the malignant hyperthermia scale, the present case was almost certainly that of a patient with MH. Prompt recognition and immediate treatment with dantrolene administration and body cooling effectively reversed a potentially fatal syndrome. This was hence a valuable case of a patient with postoperative MH that led to a confirmed diagnosis by CICR.

Anesthetic considerations in hyperparathyroid crisis: A case report
Introduction:
Hyperparathyroid crisis is a rare and potentially life-threatening complication of severe calcium intoxication. Parathyroidectomy is the only curative method for hyperparathyroid crisis. Several case reports and case series have been published on the medical and surgical treatments for hyperparathyroid crisis, however, few reports have focused on the associated perioperative anesthetic management.
Patient concerns:
A 48-year-old Chinese woman presented with a 2-week history of nausea and vomiting and complained of mental status alteration including confusion and agitation in the 24 hours prior to...

Overlapping Mechanisms of Exertional Heat Stroke and Malignant Hyperthermia: Evidence vs. Conjecture
AbstractExertional heat stroke (EHS) and malignant hyperthermia (MH) are life-threatening conditions, triggered by different environmental stimuli that share several clinical symptoms and pathophysiological features. EHS manifests during physical activity normally, but not always, in hot and humid environments. MH manifests during exposure to haloalkane anesthetics or succinylcholine, which leads to a rapid, unregulated release of calcium (Ca2+) within the skeletal muscles inducing a positive-feedback loop within the excitation –contraction coupling mechanism that culminates in heat stroke-like symptoms, if not rapidly r...

Role of injection laryngoplasty in preventing post-stroke aspiration pneumonia, case series report
Conclusion:
Injection laryngoplasty proved to be both successful and safe in improving glottic closure with immediate results in those who had failed to show a positive response after long-term swallowing rehabilitation. The positive and dramatic clinical outcomes were observed through changes in the coughing force. Our case series support the use of injection larygnoplasty as a powerful adjunctive treatment method to prevent aspiration pneumonia in post-stroke patients with vocal fold insufficiency. Pre- and post-injection peak cough flow changes may reflect improvement in glottic closure and indicate the safety of swal...

Chitosan nanoparticles release nimodipine in response to tissue acidosis to attenuate spreading depolarization evoked during forebrain ischemia.
Abstract
Stroke is an important cause of mortality and disability. Treatment options are limited, therefore the progress in this regard is urgently needed. Nimodipine, an L-type voltage-gated calcium channel antagonist dilates cerebral arterioles, but its systemic administration may cause potential side effects. We have previously constructed chitosan nanoparticles as drug carriers, which release nimodipine in response to decreasing pH typical of cerebral ischemia. Here we have set out to evaluate this nanomedical approach to deliver nimodipine selectively to acidic ischemic brain tissue. After washing a nanoparti...

Changes in electrolyte concentrations alter the impedance during ischemia-reperfusion injury in rat
brain
In this study, changes in the bio-impedance spectroscopy using a two-electrode method
with varying frequencies from 100 to 35 kHz have been assessed in a model of global cerebral
ischemia in anesthetized rats during normal, occlusion and reperfusion conditions. Global cerebral
ischemia was induced by bilateral common carotid artery occlusion for 40 min following 40 min of
reperfusion. The concentration of sodium, potassium, calcium and chloride ions in the whole rat
brain was determined by electrolyte analyzer. For the interpretation of in vivo results, changes in
electrical impedance with varying concentrati...

Acute symptomatic seizures and epilepsy after mechanical thrombectomy
ConclusionsThe incidence of PSE after mechanical thrombectomy was low in our cohort. All blood biomarkers displayed interesting sensitivity and specificity. However, the number of PSE cases was small and more studies are needed on risk factors for PSE after mechanical thrombectomy. The potential of blood markers of brain injury markers to contribute to assessment of PSE risk should be explored further.This article is part of the Special Issue "Seizures & Stroke".

Pre-anesthetic ultrasonographic assessment of the internal jugular vein for prediction of hypotension during the induction of general anesthesia
ConclusionIJV-A in the Trendelenburg position was an independent predictor of hypotension during induction. Further study is required to examine the diagnostic accuracy of IJV-A as a predictor for hypotension during induction.
