Bench-to-bedside review: hyperinsulinaemia/euglycaemia therapy in the management of overdose of calcium-channel blockers.

Hyperinsulinaemia/euglycaemia therapy (HIET) consists of the infusion of high-dose regular insulin (usually 0.5 to 1 IU/kg per hour) combined with glucose to maintain euglycaemia. HIET has been proposed as an adjunctive approach in the management of overdose of calcium-channel blockers (CCBs). Indeed, experimental data and clinical experience, although limited, suggest that it could be superior to conventional pharmacological treatments including calcium salts, adrenaline (epinephrine) or glucagon. This paper reviews the patho-physiological principles underlying HIET. Insulin administration seems to allow the switch of the cell metabolism from fatty acids to carbohydrates that is required in stress conditions, especially in the myocardium and vascular smooth muscle, resulting in an improvement in cardiac contractility and restored peripheral resistances. Studies in experimental verapamil poisoning in dogs have shown that HIET significantly improves metabolism, haemodynamics and survival in comparison with conventional therapies. Clinical experience currently consists only of a few isolated cases or short series in which the administration of HIET substantially improved cardiovascular conditions in life-threatening CCB poisonings, allowing the progressive discontinuation of vasoactive agents. While we await further well-designed clinical trials, some rational recommendations are made about the use of HIET in severe CBB overdose. Although the mechanism of action is less well understood in this condition, some experimental data suggesting a potential benefit of HIET in beta-adrenergic blocker toxicity are discussed; clinical data are currently lacking.Journal ArticleReviewinfo:eu-repo/semantics/publishe

Validation of the superior interhemispheric approach for tuberculum sellae meningioma

International audienceObjectThe objective of this study was to evaluate the ophthalmological outcome, nonvisual morbidity, and surgical complications after tuberculum sellae meningioma (TSM) removal using a superior interhemispheric approach.MethodsIn the last decade, 20 consecutive patients with TSM underwent operations using the superior interhemispheric approach. Visual acuity, visual field, and ocular fundus examination were assessed both preoperatively and 6-months postoperatively. Nonvisual morbidity was determined at an early postoperative period and at 6 months based on assessment of the Karnofsky Performance Scale score, leakage of CSF, endocrinological status, and olfactory function, which was assessed using a visual analog scale (VAS). The potential brain injury related to the approach was assessed by MRI at 6 months. Magnetic resonance imaging was then performed yearly to detect a recurrence. The mean follow up was 56.3 ± 34 months.ResultsThe primary presenting symptom for diagnosis of TSM in 20 patients (female:male ratio of 6.6:1, mean age 59.1 ± 11.1 years) was visual disturbance in 12 patients (60%), headache in 4 (20%), cognitive alteration in 1 (5%), epilepsy in 2 (10%), and accidental in 1 (5%). In a total of 40 eyes, 17 eyes in 11 patients presented with preoperative deterioration of visual acuity. Postoperatively, the visual acuity improved in 13 eyes in 8 patients (72.8%), remained unchanged in 3 eyes in 2 patients (18.2%) and deteriorated in 1 patient (9%). The nonvisual morbidity included olfactory deterioration in 7 patients (35%), and panhypopituitarism in 1 patient (5%). No patients experienced a CSF leak. The impact of olfactory deterioration on the quality of life, as estimated by a VAS score (range 0–10), was a mean of 5.7 ± 2.2 (95% CI 4.1–7.3). On the follow-up MRI, no additional lesions or recurrences were observed on the medial aspect of the frontal lobe along the surgical corridor.ConclusionsThe superior interhemispheric approach appears to be effective in resolving the problem of visual deterioration due to a TSM, without inducing surgical injury on the brain surface along the surgical corridor. Olfactory deterioration remained the challenging predominant nonvisual morbidity using this approach
