PURPOSE: The purpose of this study was to construct and test a structural equation modeling on the reproductive health behavior of single women with sexual experiences. This study employed Ajzen's Theory of Planned Behavior (TPB). METHODS: The data were collected after receipt of consent from 250 single women with sexual experiences, and analyzed using SPSS 18.0 and AMOS 18.0. RESULTS: Model fit indices for the hypothetical model were suitable for the recommended level: x²=362.407, RMR=0.065, RMSEA=0.070, GFI=0.867. TLI=0.927, CFI=0.938, IFI=0.939, and x²/dF=2.237. Intention showed direct effect with the biggest effect being on reproductive health behavior. Attitude, subjective norm and perceived behavioral control were found to have a direct effect on intention. Among them, perceived behavioral control revealed the largest influence. CONCLUSION: This study suggests that the TPB is a suitable model in explaining the reproductive health behavior of single women with sexual experience. Strategic plans for educational and intervention programs should be aimed to encourage single women to engage in reproductive health behavior.

The authors report two cases of successful reconstruction in infected nonunion of the femur involving marked shortening by compression and gradual distraction at the nonunion site using Ilizarov external fixator. At first, infection was controlled by radical excision & the administration of systemic antibiotics for four weeks and we also started compression at the nonunion site 3 days after operation. Autogenous iliac bone graft was added to strengthen the site of new bone formation lastly. In this report, the role of the compression seems to provide a good environment for distraction osteogenesis by focal necrosis and triggering inflammation. Compression and gradual distraction may be one of the treatment mordalities for nonunion of a long bone with massive bone loss or shortening, even infected.

The study was undertaken to evaluate the effect of major blood components on the CT number. The CT numbers according to the various levels of hematocrit, total protein and cholesterol were checked and analysed by the dilution of pack cell, plasma and 184 complete blood cell count samples under same scanning conditions. In case of normal protein and cholesterol level(33 samples), the CT number was increased about 5.5 hounsfield unit according to 10% increase of hematocrit level: and In case of normal hematocrit and cholesterol level(39 samles), the CT number was increased about 3.5 hounsfield unit according to 1gm% increase of protein level. CT number changes were not predictable according to the changes of cholesterol level(34 samples). From these results, we concluded that major blood components should be considered in the CT number analysis of tissue.

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: An experimental study was carried out to evaluate the morphological changes in the blood brain barrier and neighbouring brain tissue caused by Gd-DTPA in uremia-induced rabbits. MATERIALS AND METHODS: Bilateral renal arteries and veins of ten rabbits were ligated. Gd-DTPA(0.2 mmol/kg) was intravenously injectedinto seven rabbits immediately after ligation. After MRI, they were sacrificed 2 or 3 days after ligation in orderto observe light and electron microscopic changes in the blood brain barrier and brain tissue. RESULTS: MRIfindings were normal, except for enhancement of the superior and inferior sagittal sinuses on T1 weighted imagesin uremia-induced rabbits injected with Gd-DTPA. On light microscopic examination, these rabbits showed perivascular edema and glial fibrillary acidic protein expression ; electron microscopic examination showed separation of tight junctions of endothelial cells, duplication/rarefaction of basal lamina, increased lysosomes of neurons with neuronal death, demyelination of myelin, and extravasation of red blood cells. Uremia-induced rabbits injected with Gd-DTPA showed more severe changes than those without Gd-DTPA injection. CONCLUSION: Injuries to the blood brain barrier and neighbouring brain tissue were aggravated by Gd-DTPA administration inuremia-induced rabbits. These findings appear to be associated with the neurotoxicity of Gd-DTPA.

PURPOSE: Fractional exhaled nitric oxide (FeNO) has been widely reported as a marker for airway inflammationin, and FeNO have shown increased levels in the non-asthmatic patients with other atopy related diseases, such as rhinitis. Bronchial hyperresponsiveness is a characteristic feature of asthma, which is often associated with airway inflammationin allergic rhinitis. It has been suggested that asthma is associated with rhinitis, which is a link between the upper and the lower airways, beyond allergy associated inflammation in the respiratory tract. To evaluate the usefulness of FeNO measurement, as a risk factor of allergic and nonallergic rhinitis in children with asthma. METHODS: Fifty-three children included in this study were diagnosed as asthma from April through August 2005 in the Department of Pediatrics, Kyung Hee University School of Medicine. They conducted FeNO monitoring, total eosinophil count and serum immunoglobulin E at that time. We put a question to the participants' parents about the doctor diagnosed participants' manifestations (sneezing, nasal congestion, nasal itching, rhinorrhea), via a telephone interview survey or at the outpatient department in July 2011. Statistical analyses were performed using IBM SPSS ver. 18.0. RESULTS: The overall prevalence of rhinitis, among the 53 children, was 67.9%. The means of FeNO differed significantly between the two groups, being higher in children who have rhinitis symptoms and lower in asymptomatic children. (mean+/-SD, 29.4+/-24.6 to 13.6+/-11.8 parts per billion; P=0.003; T-test) CONCLUSION: To take the measurement of FeNO value in asthmatics may be a tool in the predictor of the causes of rhinitis.

Malignant hyperthermia is a metabolic and genetic disease which present with multiple signs of variable intensity and time course. Most of signs are nonspecific to malignant hyperthermia an4 it is not unusual for malignant hyperthermia-susceptible patients to under- go their first anesthesia uneventfully. Thus,the accurate prediction of preanesthetic susceptibility and early diagnosis of malignant hyperthermis can be lifesaving. Recently, some episodes of signs and symptoms suggestive of malignant hyperthemia after spinal an- esthesia those were suspected to be malignant hyperthermia have been reported. In our hospital, two patients suffered from signs and symptoms suggestive of malignant hyperthermia after spinal anesthesia. One patient showed severe muscle rigidity on the un- blocked upper extremities and thorax, tachycardia (120-160beat/min) and hypertension (180-160/120-100mmHg) and later he showed high fever(38-40degrees C), generalized seizure and severe acidosis. He expired the next day of operation in spite of intensive care. The other patient showed shivering, high fever(39degrees C) and elevated serum CPK level(more than 1,500IU/ L) after spinal anesthesia. Intensive treatment with cooling was immediately initiated. Then, he recovered completely 6 hours later. His mother and a brother showed increased serum CPK level(91,112IU/L, respectively), too. Although we could not performed confirmatory diagnostic test, signs and symptoms were very similar to those of malignant hyperthermia. So, we suspected that it might be malignant hyperthermia.

Osteochondroma is a benign bone tumor that is most commonly found in the extremities and is prevalent in adolescents, with a peak incidence before the age of 20 years. Herein, we present a rare case of a 33-year-old man with an asymptomatic tumor on the right anterior rib that was pathologically confirmed to be a rib osteochondroma after surgical excision. We describe the computed tomography and magnetic resonance imaging (MRI) procedures and highlight the importance of MRI as a critical diagnostic tool for osteochondroma.
