Case ReportsSuccessful treatment with hydrocortisone for heat stroke with critical illness-related corticosteroid insufficiency: transitional changes in serum cytokine and cortisol concentrations.
A 37-year-old man was transferred to our emergency center because of heat stroke with circulatory shock. Despite aggressive body cooling, massive intravenous transfusion, and supply of inotropic agents, shock was persistent. To evaluate adrenal function, an adrenocorticotropic hormone stimulation test was conducted and the results indicated that he had critical illness-related corticosteroid insufficiency (CIRCI) as a result of adrenal insufficiency. ⋯ He was discharged on the thirty-seventh hospital day. Serum cortisol and cytokine concentrations were initially high and the cytokines decreased subsequent to hydrocortisone administration. It is speculated that CIRCI is an exacerbating factor in heat stroke, and hydrocortisone may be a potential therapeutic approach in such patients.

Comparative StudyComparison of Parker-tipped and Murphy-tipped tracheal tubes in Airway Scope-assisted intubation in a manikin.
We tested our hypothesis that a Parker-tipped tracheal tube could improve the reliability of tracheal tube passage as compared to a Murphy-tipped tracheal tube during Airway Scope-assisted intubation in a manikin. ⋯ When the advancement of a conventional tracheal tube during Airway Scope-assisted intubation is likely to result in collision with the glottis or other laryngeal structures, the selection of a Parker-tipped tracheal tube is a better option.

Case ReportsFunctional analysis of ryanodine receptor type 1 p.R2508C mutation in exon 47.
Malignant hyperthermia (MH) is a pharmacogenetic disorder of intracellular calcium homeostasis with an autosomal dominant inheritance. Most of the reported mutations in exon 47 were identified in Asian patients. However, no functional analysis of p.R2508C has been performed. We therefore conducted a functional analysis of the mutation by altering calcium homeostasis in human embryonic kidney (HEK) 293 cells transfected with the p.R2508C mutation in exon 47 of the ryanodine receptor 1 (RYR1). ⋯ We demonstrated that the transfected RYR1 mutant was more sensitive to caffeine and 4CmC than wildtype RYR1. These findings suggest that the p.R2508C mutation may be pathogenetic for susceptibility to MH.

For direct laryngoscopy, we compared midline and left-molar approaches with respect to ease of intubation, using a Macintosh blade. We investigated the relationship between failure of the left-molar approach and preoperative risk factors for difficult intubation. ⋯ Difficulty in the insertion of the endotracheal tube limits the efficacy of the left-molar approach. It is not possible to predict the failure of intubation with the left-molar approach by considering the preoperative risk factors.

Case ReportsAnesthetic management of renal transplantation in a patient with familial dysautonomia.
Familial dysautonomia is an inherited disorder characterized by autonomic and sensory nervous system neuropathy resulting in extremely labile blood pressure (severe hypertension followed by hypotension). As more patients with familial dysautonomia reach adulthood due to improved medical treatment, perioperative encounters of patients with familial dysautonomia will increase. This report is the first adult case to describe an anesthetic management of kidney transplantation for an adult familial dysautonomia patient. The clinical manifestations of this disease and rationale of our anesthetic management are discussed.
