Endovascular aortic repair (EVAR) was relatively safe, and became a widely performed procedure. If aortic dissection (AD) occurred in patient with previous EVAR, it could cause fatal complications like endograft collapse. Surgical treatment was limited in this situation for comorbidities and complex anatomies. Here we report a rare case of acute type B AD developed following trans-radial coronary intervention in a patient with previous EVAR of abdominal aortic aneurysm, which was treated with thoracic EVAR.

OBJECTIVES: The objectives of this study is to compare the differences of fetal heart rate (FHR) variables between preterm and term pregnancies after acoustic stimulation using computerized analysis of fetal heart rate. METHODS: Eighty-two normal pre-term and term pregnancies entered to this study after conventional 20-minutes nonstress test(NST) and 10-minutes acoustic stimulation test (AST). Acoustic stimulations were performed using Fetal Acoustic Stimulator (Model 146, Corometrics, US). We analyzed the FHR response after acoustic stimulation using our on-line computerized FHR analysis system, HYFM-I & II software. The changes of loss of signal, baseline FHR, variability, number of fetal movements, and number of FHR accelerations were analyzed numerically. RESULT: The mean baseline FHR was increased in term pregnancies from 141+/-7.0bpm to 152.7+/-9.7bpm, and in preterm pregnancies from 144.6+/-6.8bpm to 156.8+/-10.2bpm, respectively. The mean baseline FHR was significantly increased in both term and preterm pregnancies (p<0.01. paired t-test). The variability of FHR was increased in term pregnancies from 18.2+/-6.4bpm to 22.6+/-5.0bpm and in preterm pregnancies from 17.8+/-5.5bpm to 22.7+/-5.9bpm, respectively. The variability of FHR was also significantly increased in both term and preterm pregnancies. (p<0.01. paired t-test) CONCLUSION: The mean baseline FHR and the variability of FHR was significantly increased both preterm and term pregnancies. But the difference of each FHR variables between preterm pregnancies and term pregnancies was not statistically significant in this study.

Bond strength of luting cements to dentin is a critical consideration for success of complete cast crowns. This study was performed to evaluate the relationship between surface characteristics of teeth prepared for complete cast crowns and retention of cemented restorations. Eighty artificial crowns were cast for standardized complete crown tooth preparations accomplished with the use of a special device on recently extracted human teeth. Coarse diamond(#102R, Shofu) and superfine finishing diamond(#SF102R, Shofu) burs of similar shape were used. Crowns in each group were randomly subdivided into four subgroups of 10 for luting cements selected for this study: zinc phosphate cement (FLECK'S), polycarboxylate cement (Poly-F), reinforced glass ionomer cement (Fuji PLUS), and adhesive resin cement (Panavia 21). Retention was evaluated by measuring the tensile load required to dislodge the artificial crown from tooth preparations with an Instron testing machine, and analysed by one-way ANOVA and Student's t-test. The obtained results were as follows ; 1. When tooth preparation was done with coarse diamond bur, retentive force was diminished in order of Panavia 21, Fuji PLUS, FLECK'S, and Poly-F. Retentive forces showed the significant difference between Fuji PLUS group and FLECK'S group(p<0.001). 2. When tooth preparation was done with superfine diamond bur, retentive force was diminished in order of Fuji PLUS, Panavia 21, FLECK'S and Poly-F. Retentive forces showed the significant difference between Panavia 21 group and FLECK'S group(p<0.001). 3. Retentive force in coarse tooth surfaces was significantly higher than that in superfine tooth surface with all luting cements(p<0.001), and cement residues were almost retained with in the cast crown in all groups.

Purpose: Cystoscopy, as with other endoscopic procedures, is a fearful and painful for the majority of patients. To this reduce fear, pain and discomfort, the routine administration of sedative drugs, such as midazolam and propofol, is widely accepted for a gastrointestinal endoscopy. There have also been some studies on midazolam anesthesia during cystoscopy. However, the effects and safety of propofol anesthesia during cystoscopy have not been established. Therefore, the effects and safety of propofol anesthesia during cystoscopy were investigated in this study. Materials and Methods: 200 male patients were divided into 2 groups: Group A consisted of 80 patients sedated using 1mg/kg propofol IV, and group B consisted of 120 patients who received normal saline IV instead of propofol. All patients received 90mg diclofenac IM for pain control. There were no significant differences in the ages and weights between the two groups. The vital signs and oxygen saturation were monitored before, during and after the cystoscopy. The degree of pain and satisfaction of the patients and urologist were measured. Results: The pain scales were significantly reduced in group A compared to group B. Group A patients and the operator were also significantly more satisfied than those in group B. Although the blood pressure, pulse rate or respiratory rate changed during the cystoscopy, they were not clinically significant and there was no need for additional treatment. 12 patients in group A showed temporary hypoxia; however, they were treated with oxygen administration and recovered within several minutes. Conclusions: Propofol anesthesia during cystoscopy can be performed safely and effectively as an outpatient procedure, as long as there is adequate preparation and monitoring.

Prediction of individual outcome after cardiopulmonary resuscitation is of major medical, ethical, and socioeconomic interest but uncertain. We experienced the case thats the patient got complete neurologic recovery after the 123th day firm cardiac arrest, who had been suspected to go with poor prognosis because she got the findings of Glasgow Coma Scale 4, severe diffuse encephalopathy on encephalogram and generalized tonic-clonic seizure at the 4th day. Recently, a 29 year-old women who sustained from respiratory arrest induced presumably by sedative and anticonvulsant therapy for control of seizure that happened during local lidocaine anesthesia far mamoplasty was transfered to our emergency medical center from local private plastic office. Arrest time was about 20 minutes. On hospital arrival, she had a pulseless bradyasystole and no respiration, but spontaneous circulation was restored at 10 minutes artier CPR started. We started cerebral oriented resuscitation including mild hypothermia(34degrees C), hemodilution, calcium channel blocker infusion. On hospital day 4, patient's glasgow coma scale(GCS) was 4. On hospital clay 7, Brain Magnetic Resonance Imaging(MRI) showed high signal intensity on T2WI, involving the bilateral basal ganglia. After contrast administraton, marked enhancement can be seen at the lesion site. Patient's glasgow coma scale(GCS) increased step by step to 5 on 8th day, 7 on 14th day, 10 on 15th day, 13 on 17th day, 15 on 20th day. 40 days later the patient was discharged with minor neurologic abnormality including hand tremor, dysphonia, amenorrhea and Mini Mental State Examination(MMSE) score(26). Long-term Follow up revealed that all neurologic functional abnormality inducting hand tremor, dysphonia, amenorrhea and MMSE score(26) is completely recovered on 123th day after episode of cardiopulmonary arrest.

PURPOSE: To determine the effect of intraocular pressure (IOP) reduction of selective laser trabeculoplasty (SLT) on medically uncontrolled open-angle glaucoma (OAG) and the factors associated with the treatment result. METHODS: Forty-seven eyes of 47 OAG patients were enrolled for 180° SLT or 360° SLT, all under maximal tolerated medical therapy and with IOP above their target pressure. All patients were followed-up for at least 1 year after the procedure. Treatment success was defined as IOP reduction ≥20% from baseline at 12 months after SLT treatment without additional anti-glaucomatous intervention. RESULTS: The treatment success rate was 65.96%. Baseline IOP was 23.84 ± 4.52 mmHg in the success group and 21.44 ± 2.97 mmHg in the failure group (p = 0.035). Significant mean IOP reduction was observed at 6, 9, and 12 month follow-ups (p = 0.001 at 6 months; 0.041 at 9 months, and <0.001 at 12 months). The success rate did not vary significantly by sex (p = 0.362), age (p = 0.081), history of cataract surgery (p = 0.470), number of medications (p = 0.857), duration of medication (p = 0.613), or angular degree of SLT treatment (180° vs. 360°) (p = 0.137). There was a positive correlation between mean baseline IOP and mean reduction of IOP from baseline in the success group (p < 0.001, r = 0.861), while there was no such correlation in the failure group (p = 0.272, r = −2.921). CONCLUSIONS: SLT was an effective treatment for IOP reduction until 12 months in medically uncontrolled OAG patients. A greater amount of IOP reduction is expected in patients with higher baseline IOP in the success group.
