CONTEXT: Brain oxidative reactions are involved in epilepsy as well as neurodegenerative diseases. In animal convulsion models, some anticonvulsants have been found to suppress oxidative reactions associated with convulsions. However, the effect of anticonvulsants on brain oxidative reactions has not fully been clarified. OBJECTIVE: Midazolam and phenobarbital are often used as an intravenous anesthetic, and are known to have anticonvulsive effect, but antioxidative effect of these drugs has rarely been studied. Thus, the purpose of this study was to evaluate the effects of these drugs on the degree of convulsions and brain oxidative reactions in an animal convulsion model. MATERIALS AND METHODS: In order to evaluate brain oxidative reactions, we measured malondialdehyde (MDA) level and heme oxygenase (HO)-1 mRNA expression level in the brain of mice in a convulsion model generated by a single injection of pentylenetetrazole (PTZ). We evaluated the effects of midazolam and phenobarbital on the degree of PTZ-induced convulsions and on the changes in brain MDA level and HO-1 mRNA expression level. RESULTS: After PTZ injection, severe convulsions were observed in all mice. MDA level was increased in the whole brain, while HO-1 mRNA expression level was increased only in the hippocampus. Both midazolam and phenobarbital prevented the convulsions and suppressed the increase in both MDA level and HO-1 mRNA expression level in the brain. CONCLUSION: In this study, both midazolam and phenobarbital suppressed PTZ-induced MDA and HO-1 reactions in the brain, suggesting that these drugs inhibit brain oxidative reactions in a convulsion model.

CONTEXT: Interleukin-6 (IL-6) plays an important role in immune and inflammatory responses. Midazolam has been reported to modulate IL-6 response. Cyclooxygenase (COX) inhibitors, which are used together with midazolam in some patients undergoing surgery, also modulate it. We hypothesized that their combination results in eliciting the synergistical effect on the IL-6 response. OBJECTIVE: The aim of the present study was to evaluate the effect of the combination of midazolam and a COX inhibitor on IL-6 production. MATERIALS AND METHODS: Peripheral blood mononuclear cells (PBMCs) were isolated from healthy volunteers and incubated with lipopolysaccharide (LPS), midazolam, and/or COX inhibitors, including indomethacin, SC-560, a COX-1 selective inhibitor, and NS-398, a COX-2 selective inhibitor. The supernatant concentrations of IL-6 and prostaglandins (PGs), including PGE2, PGF2α, PGD2, and 15-deoxy-Δ¹²,¹⁴-prostaglandin J2 (15dPGJ2) were measured. RESULTS: Midazolam had no effect on IL-6 production in the cells incubated for 12 h, and any COX inhibitors also had no effect. However, the combination of midazolam and NS-398 significantly inhibited it. Midazolam raised the concentration of 15dPGJ2 in the supernatant of the cells, but not the concentration of other PGs. DISSCUSSION AND CONCLUSION: The results in the present study demonstrated that the combination of midazolam and a COX-2 inhibitor inhibited LPS-induced IL-6 production in human PBMCs even if each drug separately did not have any effect on it. The finding suggests that their combination is effective against excessive IL-6 production such as severe inflammatory response and that the effect of midazolam on IL-6 production is possibly elicited via 15dPGJ2.

In sedation of dental patients with moderate or severe mental retardation, it is difficult to identify the optimum sedation level and to maintain it appropriately. Moreover, many patients have concomitant epilepsy and are medicated with oral antiepileptic drugs (AEDs), which influence the drug-metabolizing enzymes. In particular, valproate (VPA) has been demonstrated to inhibit propofol metabolism in vitro. Therefore, the objective of the present study was to investigate the clinical influence of oral VPA on the required dose of propofol for sedation, with use of a prospective cohort study design. We studied 45 patients with moderate or severe mental retardation who underwent dental treatment under sedation. Propofol was infused, and sedation was maintained at the same level in all patients using a bispectral index (BIS) monitor. After the completion of treatment for the scheduled patients, patients were divided into those with oral VPA treatment (VPA group: 20 patients) and without any oral antiepileptic treatment (control group: 25 patients). The propofol dose required for sedation and times to the recovery of the eyelash reflex and spontaneous eye opening were evaluated. The median required propofol doses in the VPA and control groups were 4.15 (range 1.97-5.88) and 5.67 (2.92-7.17) mg/kg/h, respectively. We observed a statistically significant difference between the two patient groups with respect to median VPA dose (p < 0.01). However, no statistically significant differences were noted in the time until eyelash reflex recovery or spontaneous eye opening between the two groups. The results suggest that oral VPA reduces the dose of propofol required for sedation during dental treatment in patients with moderate or severe mental retardation.

51歳男。左上前歯部のブリッジ脱離による審美障害を主訴とした。重度の異常絞扼反射を有するため、静脈内鎮静法で処置することになり、初回はミダゾラムとプロポフォールを併用したが、絞扼反射を完全に抑制できなかった。そこで、プロポフォールとレミフェンタニルを用いた鎮静法に変更したところ、絞扼反射を良好に抑制し、合併症を認めることなく治療を行うことができた。また、約1年間に計10回、静脈内鎮静法を用いて処置を行ったが、10回目のプロポフォールの平均投与速度は初回の53.5%まで減少し、絞扼反射が脱感作傾向を呈した。重度の異常絞扼反射を有する患者の鎮静法では、処置中の異常絞扼反射の抑制だけでなく、反射の閾値を上昇させる点において、プロポフォールとレミフェンタニルを併用した鎮静法が有用と思われた。

Treatment for acute lymphoblastic leukemia (ALL) mainly consists of chemotherapy, irradiation and bone marrow transplantation. In terms of long-term treatment effects, dental abnormalities and chronic graft-versus host disease (GVHD) are problems. We present a patient surviving relapse of ALL at one year of age. He had extreme dental abnormalities and multiple caries. Most of his permanent teeth were abnormal, and multiple caries were observed. Since he had a strong vomiting reaction to dental treatment, general anesthesia was given. During the general anesthesia, much sputum was aspirated because of chronic GVHD. His dental condition was worse than other cases reported previously. Since the survival rate has increased recently, the dental effects of ALL treatment have become significant. Especially, in patients undergoing total body irradiation at under 2 years of age, it is highly likely that dental problems will occur in the future.

STUDY OBJECTIVE: To investigate the use of propofol sedation using Bispectral Index (BIS)-guided target-controlled infusion (TCI) in dental patients with intellectual disability. DESIGN: Single-center, prospective, randomized clinical trial. SETTING: Academic outpatient clinic. SUBJECTS: 40 ASA physical status 1 and 2 patients with intellectual disability. INTERVENTIONS: Patients were randomized to two groups. The manual control (MC) group (n = 20) had sedation by manually controlled infusion of propofol without a BIS index monitor. The BIS-TCI group (n = 20) had sedation by BIS-guided TCI of propofol. MEASUREMENTS: The required dose of propofol, recovery time for the eyelash reflex, and spontaneous eye opening times were recorded. MAIN RESULTS: BIS-TCI significantly reduced the dose of propofol and shortened the recovery times for eyelash reflex and spontaneous eye opening. CONCLUSION: Propofol sedation using BIS-guided TCI is a useful and safe method in the management of patients with intellectual disability.

Propofol and midazolam have a synergistic anesthetic action. One of the reasons for this is thought to be the inhibitory effect of propofol on midazolam metabolism. However, because both drugs bind strongly to serum protein, their interaction may not only involve the effects of propofol on midazolam metabolism, but may also involve propofol's effects on serum protein-binding. Against this background, we investigated the characteristics of midazolam binding to serum albumin, and evaluated the effects of both propofol and ketamine on this binding. Midazolam was added to a serum albumin solution with propofol or ketamine, and, after incubation for 1 h, albumin-free solution was separated from the sample and the midazolam concentration was measured using a high-performance liquid chromatography system. The albumin-unbound rate of midazolam was evaluated and compared with the rate in the control solution (only midazolam). Propofol significantly raised the rate of albumin-unbound free midazolam, while ketamine had no effect on the binding of midazolam to serum albumin. These findings suggest that the increase in albumin-unbound free midazolam brought about by propofol is involved in the synergistic effect of these two agents.

The oral administration of midazolam has often been used for sedation in pediatric patients. However, oral administration of an intravenous formulation of midazolam is difficult for younger pediatric patients because of its bitter taste. Liposomes have been developed as vesicles encapsulating various kinds of drugs to serve as a medical drug-delivery system. Thus, the aim of the present study was to produce pH-sensitive liposomes encapsulating midazolam and to evaluate its pharmacokinetics on rabbits. Liposome-encapsulated midazolam was produced from hydrogenated L-α-phosphatidylcholine, cholesterol, dipalmitoylphosphatidic acid, and midazolam. The capacity of liposomes to encapsulate midazolam (encapsulation efficiency), stability of encapsulation, and release efficiency were evaluated in vitro. Further, the produced liposome-encapsulated midazolam solution was orally administered to rabbits in vivo. As a result, midazolam was encapsulated by liposomes with a high encapsulation efficiency and was stably encapsulated in a physiological medium. Further, the produced liposomes rapidly and effectively released midazolam in an acidic medium in vitro. When the liposome-encapsulated midazolam solution was orally administered to rabbits, the time to achieve the maximum plasma concentration of midazolam after administration was slightly longer, but both the maximum plasma concentration and area under the concentration-time curve were higher than those receiving midazolam solution. In conclusion, we produced pH-sensitive liposome-encapsulated midazolam, which remained stable in a physiological medium and showed efficient release in an acidic environment. The results suggest that it is possible to clinically use liposome-encapsulated midazolam for oral administration as a useful drug-delivery vehicle.

Iron, a source of oxidative stress, plays a major role in the pathology of neurodegenerative disease. In Alzheimer's disease, the hippocampus is vulnerable to oxidative stress, leading to impairment in memory formation. In our previous study, a brain oxidative reaction was induced after intraperitoneal injection of ferric nitrilotriacetate (Fe-NTA). However, since only a small amount of iron reached the brain in the previous study, Fe-NTA was administered into the hippocampus using an osmotic pump in this study. After continuous injection of Fe-NTA for 2 weeks, a high level of apoptotic change was induced in the hippocampus, in accordance with the iron localization. After injection for 4 weeks, the hippocampus was totally destroyed. A small amount of iron infiltrated into the cerebral cortex and the striatum, and deposition was observed at the choroid plexus and ependymal cells. However, no apoptotic reaction or clear tissue injury was observed in these areas. In addition, muscarinic acetylcholine receptors (M1, M2, and M4) were decreased in both the cortex and hippocampus while it increased in the striatum. Thus, the hippocampus is likely vulnerable to oxidative stress from Fe-NTA, and the oxidative stress is considered to bring the disturbance in the muscarinic acetylcholine receptors.

Some dental patients have histories of adverse reactions to local anesthesia. The aim of the present study was to investigate the frequency of allergy to local anesthetics of dental patients who had histories of adverse reactions to local anesthesia based on the results of allergy tests in our institute over a period of 5 years. We investigated the past medical records of dental patients retrospectively, and twenty patients were studied. Three of the 20 showed a positive or false-positive reaction in the intracutaneous test, and one patient showed a false-positive reaction in the challenge test. Our results suggest that the frequency of allergy to local anesthetics is low even if patients have histories of adverse reactions to local anesthesia. However, allergy tests of local anesthetics should be performed in patients in whom it is uncertain whether they are allergic.
