The behavioral disturbances such as agitation, aggression and wandering oc-curred in the geriatric patients have imposed much burdens on the caregivers. The origin of the behavioral disorders in the geriatric patients were identified to be based on the multidimensional interaction of the biological, psychological and social factors. There are no satisfactory instrum-ents for assessment of behavioral disorders in the geriatric patients. Furthermore, the functional assessments are also required to evaluate the environmental events to influence the problem beh-aviors in the geriatric patients.

< 0.05). The incidence of emergence agitation was 17% in the subtenons lidocaine injection group, which was significantly lower than in the control group (36%) (P < 0.05). CONCLUSIONS: A lidocaine injection into the subtenons space reduces emergence agitation after sevoflurane anesthesia in pediatric strabismus surgery.

BACKGROUND: We designed this study to find the appropriate dose of fentanyl for the prevention of emergence agitation in pediatric tonsillectomy patients under sevoflurane anesthesia. METHODS: Sixty pediatric patients receiving sevoflurane anesthesia for tonsillectomy was assigned to 3 groups. Fentanyl 0.5microgram/kg (group 1), 1.0microgram /kg (group 2), or 1.5microgram/kg (group 3) was administered intravenously 10 min before the end of surgery. Agitation score was checked at the postanesthesia care unit. RESULTS: The results showed a lower incidence of severe agitation in groups 2 and 3 than in group 1. There was no difference between groups 2 and 3. CONCLUSIONS: For preventing emergence agitation after sevoflurane anesthesia, we recommend using fentanyl in a dose of more than 1.0micrgram/kg.

Behavior disturbances in dementia have many causes, and it is difficult to judge the effectiveness of any method as well as to classify and choose the right agents or methods of treatment. Because agitated behavior disturbances are intermittent phenomena, it is not certain that the change of symptom is response of treatment or incidental. We should help elderly people with risk of dementia, including the preventive intervention and various treatment strategies for the last stages of life. To the comprehensive treatment of behavioral disturbance of patients with dementia, adequate medical resources are essential through organized medical delivery system as well as environmental modification, family management and pharmacotherapy.

BACKGROUND: It is well known that sevoflurane anesthesia is associated with emergence agitation (EA) in children, and that fentanyl may reduce its incidence. However, in case of midazolam, there have been conflicting reports. Therefore, we measured the effect of midazolam on EA after sevoflurane anesthesia and compared it with that of fentanyl. METHODS: Sixty pediatric patients receiving sevoflurane anesthesia for tonsillectomy was assigned to 3 groups. Saline 0.1 ml/kg (group P), midazolam 0.1 mg/kg (group M), or fentanyl 1 microgram/kg (group F) was administered intravenously 10 minutes before the end of surgery. The incidences of over-sedation (OS) and EA were checked three times at the postanesthesia care unit. RESULTS: Group M had a tendency to show a high incidence of OS, but its incidence of EA was not different from the other groups. In group F, OS and EA were less frequent than in groups P and M. CONCLUSIONS: After sevoflurane anesthesia for tonsillectomy, fentanyl effectively prevented EA, but midazolam elicited OS and was ineffective at preventing EA.

INTRODUCTION: Eliminating the residual debris and bacteria in the root canal system is one of the main purposes of the endodontic treatment. However, the complexity on the anatomy of the root canal system makes it difficult to eliminate the bacterial biofilm existing along the root canal surface and necrotic pulp tissue by mechanical instrumentation and chemical irrigation. Recently, more effective irrigant delivery systems for root canal irrigation have been developed. The purpose of this review was to present an overview of root canal irrigant delivery techniques and devices available in endodontics. REVIEW: The contents of this paper include as follows; - syringe-needle irrigation, manual dynamic irrigation, brushes - sonic and ultrasonic irrigation, passive ultrasonic irrigation, rotary brush, RinsEndo, EndoVac, Laser CONCLUSION: Though technological advances during the last decade have brought to fruition new agitation devices that rely on various mechanisms, there are few evidence based study to correlate the clinical efficacy of these devices with improved outcomes except syringe irrigation with needle and ultrasonic irrigation. The clinicians should try their best efforts to deliver antimicrobial and tissue solvent solutions in predictable volumes safely to working length.

In order to avoid contamination attributed to Vanbreuseghem hair haiting technique in the laboratory, the author contrived the following modified method. After adding 100ml of antibiotics solution (mixture of 500mg of Cyclohexamide, 20, 000u of Penicillin and 40mg of Streptomycin in 1,000ml of distilled water) in PVC phial containing 100gm of soil, it was gently agitated for an hour and lefted to be settled for 12 hours. The suspended solution obtained and a batch of horse hair were randomly distributed on a Petri dishfitted with blue cloths, then cultured at 24C'. The overall results obtained from this modified method were not as satisfying as that of the Vanbreuseghem method but a few advantages such as simplicity of the procedure and significantly lower laboratory contamination implicated its practicality. Furthermore, this method was also found to be useful in the first isolation of infected animal hairs, hair perforation tests and as a substitution for artificial media. For the cross mating, a patch of blue cloths was laid on top cf moist sterilized soil evenly spreaded on a Petri dish. Then hair-baiting procedure was performed and good results were obtained.

Subaortic left brachiocephalic vein is a rare congenital anomaly that is sometimes found in the normal population. We report here on a case of subaortic left brachiocephalic vein that was detected incidentally by performing contrast transesophageal echocardiography (TEE) with using agitated saline and computed tomography (CT).

BACKGROUND: The effectiveness of preemptive analgesia is still controversial. This study was designed to compare the effects of nalbuphine used in the pre-anesthesia period and after surgery for pain control when performing adenoidectomy or tonsillectomy in children. METHODS: Two hundreds four patients (aged 3 to 12 years) were randomly allocated into two groups: the preemptive group (group P, n = 98) and the intraoperative group (group I, n = 106). Nalbuphine 0.1 mg/kg was administered into the patients before induction of anesthesia in group P and it was injected at least 10 minutes after the beginning of surgery in group I. The anesthesia was performed in the conventional fashion. The pain score, the sedation score and the agitation score were checked and recorded in the postanesthetic room (PAR) at arrival (0), at 15 minutes and at 30 minutes. RESULTS: The pain scores for PAR 0, 15 and 30 minutes were significantly lower in group I than those in group P. The other sedation scores or agitation scores were similar in both groups. CONCLUSIONS: Nalbuphine used during the pre-anesthetic period was less effective than that used in the intraoperative period for pain control when performing adenoidectomy or tonsillectomy in children.
