This study was performed to evaluate the effect that screw number and length have on the ability of two types of plate to resist vertical masticatory force. Five trials were done with two, four, or six screws, using screws 4 mm, or 12 mm in lenght and mini bone plates or mini compression plates. The fractured ribs were subjected to increasing weights until failure. With the mini bone plate, increasing the number of screws increased the weight resisted than screw length. For the mini compression plate, increasing screw length and the number of screws increased weight resisted.

The purpose of this experiment was to determind whether the gold electrodeposit on Pd-Ag and Ni-Cr alloys influences on the shear bond strength between veneering resin and silicoated metal surface. All the metal specimens were sandblasted with 250microneter aluminum oxide and followed by silicoating and resin veneering. According to the metal surfaces to be veneered, experimental groups were divided into five. Group Prec : Gold alloy without gold coating Group Semi : Pd-Ag alloy without gold coating Group Base : Ni-Cr alloy without gold coating Group Semi-G : Pd-Ag alloy with gold coating Group Base-G : Ni-Cr alloy with gold coating All specimens were thermocycled 1,000 times at temperature of 5degrees C to 55degrees C. The effects of gold electrodeposit on the shear bond strength between resin and metal interface were measured and fractured surface of the resin veneered metal was examined under the scaning electron microscope. The following results were obtained 1. The shear bond strength between resin and metal was 64.51+/-11.11Kg/cm2in Prec group, 62.77+/-11.23Kg/cm2in Base group and 58.97+/-9.20 Kg/cm2in Semi Group. There was no significant difference among the groups. 2. The bond strength in groups Semi-G and Base-G decreased about 17%, compared to the non-gold-electrodeposit groups(Semi, Base). 3. In groups of non electrodeposit(Prec, Semi, Base), fracture occurred at the interface between alloy and resin, while fracture interface was observed between gold coating and resin in group Semi-G, and between metal substrate and gold coating in group Base-G resp[ectively.

OBJECTIVES: More than half of the elders suffer from chronic sleep disturbances. Moreover, sleep disturbances are more prevalent in patients with depressive disorder than in community dwelling elderly. In this study, we aim to estimate the risk factors of poor sleep quality and its effect on quality of life in patients with late life depression. METHODS: This study included 159 depressive patients aged 65 years or older who completed Pittsburgh Sleep Quality Index (PSQI). A global PSQI score of 5 or greater indicates a poor sleeper. Structural diagnostic interviews were performed using the Korean version of Mini International Neuropsychiatric Interview (MINI). Depression was evaluated by the Korean form of Geriatric Depression Scale (KGDS). Global cognition was assessed by Mini-Mental State Examination in the Korean version of the Consortium to Establish a Registry for Alzheimer's Disease assessment packet. Quality of life was evaluated by the Korean version of Short-Form 36-Item Health Survey (SF-36). RESULTS: The frequencies of poor sleepers were 90.5% in major depressive disorder, 71.8% in minor depressive disorder, 47.1% in subsyndromal depressive disorder, and 73.0% in all types of depressive disorders. Multivariate logistic regression analysis indicated that female [odds ratio (OR) = 2.83, 95% confidence interval (CI) = 1.20-6.67] and higher KGDS score (OR = 1.13, 95% CI = 1.05-1.21) were risk factors of poor sleep quality in patients with late life depression. In the analysis of ANCOVA adjusted for age, gender, education and KGDS score, the mean scores of vitality mental health and mental component summary of SF-36 were lower in poor sleepers than in good sleepers. CONCLUSIONS: Poor sleepers among patients with late life depression are very common and are associated with female and higher KGDS scores. Poor sleep quality causes a significant negative effect on mental health quality. So researchers and clinicians should be more vigilant in the evaluation and treatment of sleep disturbances in patients with late life depression.

BACKGROUND: Morphine for the intravenous patient controlled analgesia (IV-PCA) provides effective postoperative pain control, but it has side effects such as itching, nausea and vomiting. Meanwhile, butorphanol, a synthetic potent agonist-antagonist narcotic with low incidence of adverse side effects and minimal addiction, produce adequate analgesia for postoperative pain. The purpose of this study was to compare the suitability of butorphanol combining with or without morphine with that of morphine in terms of relieving postoperative pain and incidence of side effects. METHODS: Sixty ASA physical status I or II female patients undergoing total abdominal hysterectomy were randomly allocated into one of three groups according to type of drug used (n=20 for each group). The groups were divided to group M (morphine 100 mg), group M B (morphine 50 mg+butorphanol 10 mg) and group B (butorphanol 20 mg). Drugs for each group mixed with 90 ml of normal saline (total amount: 100 ml) for infusion. Loading dose, PCA dose, lockout interval, mode of infusion was 0.05 ml/kg, 0.02 ml/kg, 8 minute, and PCA only, respectively. In each group, visual analog scale (VAS), pain score, sedation score, degree of satisfaction, total amount of drug used, history of attempt/injetion and incidence of side effects were checked. RESULTS: There were no significant differences in analgesic effects and degree of satisfaction among three groups, but incidence of side effects (especially pruritis) were less in group M+B and B compared with group M (p<0.05). CONCLUSIONS: Butorphanol showed comparable postoperative pain relief and marked less side effects compared with morphine. Butorphanol was considered as a useful drug for postoperative pain relief using IV-PCA.

INTRODUCTION: Several methods, including loss of eye lash (eyelash) reflex and loss of verbal contact, have heen used as criteria for estimating the optimal hypnosis for anesthesia induction. However, these methods are too objective. We examined the hypnotic dose response of etomidate, using a bispectral index as a more subjective criterion for anesthesia induction. METHODS: Fourty-Five ASA I or II adult patients scheduled for elective orthopedic surgery were randomly allocated to three groups according to induction dose of etomidate. They were Group 1: 0.1 mg/kg ; Group 2: 0.15 mg/kg; Group 3: 0.2 mg/kg (n = 15 for each group), respectively. Etomidate diluted as 10 ml in a syringe injected through an 18G forearm intravenous catheter, using a syringe pump at the rate of 20 ml/min. Observer's Assessment of Alertness/sedation (OAA/S) scale of 1 was considered optimal for hypnosis. Bispectral index, OAA/S scale, and vital signs were checked every minute until spontaneous eye opening after end of drug infusion. Also, the correlation coefficient between BIS and OAA/S scale was checked for evaluating the bispectral index; this was a useful tool for estimating the degree of hypnosis. RESULTS: BIS and OAA/S showed their lowest scores around 60 sec. after the etomidate injection, which was very different from time to peak effect known to be the 2 min. The correlation coefficient (r) between BIS and OAA/S was 0.84 on average, suggesting the BIS as an good subjective indicator of optimal hypnosis for anesthesia induction. Vital signs were stable in all groups. Hypnotic ED50 and ED95 were 0.12 and 0.19 mg/kg, respectively. CONCLUSIONS: Bispectral index can be a useful tool for estimating the optimal hypnosis for anesthesia induction. Hypnotic ED50 of etomidate was 0.12 mg/kg.

PURPOSE: This study investigated the need for information and social support in parents of children with epilepsy. METHODS: A total of 119 parents of children with epilepsy were recruited and asked to fill out questionnaires. RESULTS: Of 119 parents, two-third reported that they received full and sufficient information about their child's disease and its management but one-third felt the information was insufficient and incomplete. Most parents (62.2%) felt at loss when their child had a seizure, either at home or at school. They wanted information on the causes of seizures, adequate steps deal with seizure and steps they should take to become adequate and supportive parents for their children. However, most parents were reluctant to disclose the disease or to receive support from outsiders. CONCLUSION: Regardless of the fact that most parents received sufficient information about the management of epilepsy, they felt at a loss when their child had a seizure attack. Therefore nurses should give specific instruction on seizure management and assess the needs of parents on a regular basis.
