Background : Conservative techniques designed to block or delay the aging process have been utilized in various ways for many years. However, their effects can be relatively minimal and short-term in most cases compared to surgery. The objective of this study was to evaluate the efficacy and safety of gold thread implantation for the treatment of periorbital wrinkles. Methods : A total of 78 consecutive patients who showed mild to severe periorbital wrinkles were deemed appropriate candidates, including 69 women and 9 men ranging from 31 to 59 years (mean, 47 years). Six gold threads about 4 cm in length were inserted subdermally in each patient at intervals of about 0.5 cm. Follow-up assessments were performed 1, 4, and 12 weeks after the procedure. The efficacy was rated by the physician using the Wrinkle Severity Rating Scale and patients who made global assessments of changes in periorbital wrinkles using the Visual Analog Scale. Adverse events were monitored throughout the course of the study. Results : The patients showed significant improvements after the procedure. There were minor complications such as foreign body sensation in the eye (2.63%) and eye pain (1.32%) that improved spontaneously without any specific treatments. Conclusions : Subdermal implantation of gold thread improves the appearance of periorbital wrinkles and does not appear to have serious side effects. Insertion of gold thread may be an effective and safe method for facial rejuvenation.
Purpose: Many researches about various surgical method for blepharoptosis have already been introduced. But researches for complications after blepharoptosis correction is relatively insufficient. So, this study was performed to recognize common complications that arised depending on the severity of blepharoptosis, levator function and surgical method. Methods: 250 patients who have underwent surgical treatment for blepharoptosis from 1987 to 2006 were employed in this study. Patients were categorized by severity of blepharoptosis, levator function and surgical method that has been used. Complications after blepharoptosis correction were analyzed. Result: Total of 64 patients had occurred complications, the specifics are as following; undercorrection 22, asymmetry 13, overcorrection 12, lagophthalmos 4, abnormal eyelid contour 4, exposure keratitis 3, ectropion 2, inclusion cyst 2, infection 1 and conjunctival prolapse 1. Among above patients, 3 patients had two kinds of complications. 21 patients was underwent secondary surgery due to complication. Conclusion: Evaluating the outcomes of the secondary surgery, the early correction was better than the late correction. The most of the complications were recovered through conservative and surgical treatments. The most of the complications (47 patients) were undercorrection, asymmetry, overcorrection and took 73.4% of the total complications. The more severe the blepharoptosis and the more poor the levator function, the rate of complications were higher. According to the operation methods, most complications were occurred in levator operation, frontalis transfer and OOM flap.
Objective : To evaluate the effect of Oriental Medical Treatment on a patient with Hypoxic Ischemic Encephalopathy followed by Cardiopulmonary Resuscitation Method : We applied various methodology of Oriental Medical Treatment including Acupuncture, Electroacupuncture, Physical treatment, Herbal Medicine, Moxibustion treatment and Western medication as well. Result: Herbal medicine was applied on the basis of the patient's history. We applied formular to remove phelgm as a pathogenic factor after Hypoxic Ischemic Encephalopathy. At the same time, considering the patient spent more than a month in ICU lacking appropriate nutrition, we used formuli on the basis of 'Deficiency of Spleen' focusing to vitalize the function of digestive system. As the condition of the patient changed, we also adapted formular accordingly. We prescribed Herbal medication to strengthen Yin and Yang equally as she got hospitalized for long time. Also we applied Acupuncture treatment and Moxibustion treatment to control Qi flow. The general condition of the patient got better with successful removal of Foley catheter and elevated Glasgow Coma scale. We used Electroacupuncture, Physical treatment and Western medication at the same to get maximized effect on relaxing the contracted muscle. According to the Modified Ashworth Scale (MAS), we have some changes in muscle spasticity but later, the effect was not that significant. Conclusion : We had a patient with Hypoxic Ischemic Encephalopathy followed by Cardiopulmonary Resuscitation. In the management of Hypoxic Ischemic Encephalopathy, Conservative treatments are the mainstream but there are not many alternatives. Therefore, We suggest that Oriental medical approach may contribute to the management of Hypoxic Ischemic Encephalopathy.

Although Nerium indicum poisoning is a globally rare occurrence, Nerium oleander poisoning is known to occur frequently in the Mediterranean regions. To our knowledge, this is the first reported case of accidental Nerium indicum poisoning in Korea. Its poisoning symptoms and signs are similar to that of digitalis poisoning, because of the presence of cardiac glycosides in Nerium indicum. A 16-year-old boy was admitted to the emergency department four hours prior to the accidental ingestion of Nerium indicum petals. The patient complained of nausea, vomiting, and dizziness. His initial vital signs were stable; laboratory blood test results were within normal levels, except for the blood digoxin level (1.5 ng/dL). An electrocardiogram (ECG) analysis showed normal sinus rhythm, progressive PR prolongation and second-degree Morbiz type I AV block. Conservative treatments including activated charcoal administration were conducted, because toxic symptoms and signs were not severe. The patient was admitted to the intensive care unit for close observation. His ECG was converted to normal rhythm after 1 day and the toxic symptoms and signs were completely resolved after 4 days.
Purpose: To report the clinical outcomes and complications of flexor hallucis longus (FHL) tendoscopy using 3 portals. Materials and Methods: Between January 2012 and April 2013, 10 patients (10 ankles) received tendoscopic surgery for the treatment of FHL tenosynovitis. Patients complaining of pain and tenderness along the course of FHL despite over 6 months of conservative treatments were indicated for surgery. The mean age was 41.7 years (range: 18-57) and the follow up period was 12.7 months (range: 6-20). Tendoscopy was performed using posteromedial, posterolateral, and plantar portals. Clinical evaluations included preoperative and postoperative visual analogue scale (VAS), American orthopaedic foot and ankle society (AOFAS) score, and patients' satisfaction. Results: Tendoscopic findings included tenosynovitis in 10 cases, degenerated vinculae in 6 cases, stenosis of the tendon at its entrance into the fibro-osseous tunnel in 5 cases, and degenerative partial tendon tear in 3 cases. Two cases had associated symptomatic os trigonum and 3 cases had posterior ankle impingement syndrome. Preoperative pain decreased from median VAS 6 (range: 4-10) to 2.1 (range: 1-5) at the last follow up and AOFAS score improved from 50.1 (range: 36-63) to 82.1 (range: 61-89) (p<0.05). Nine patients were satisfied or very satisfied with the outcome. Injury of the lateral plantar nerve occurred in one case. Conclusion: FHL tendoscopy using 3 portals is a feasible and useful minimal invasive surgical technique for the management of FHL tenosynovitis.

Objectives: Extensively destroyed teeth are commonly restored with composite resin before cavity preparation for indirect restorations. The longevity of the restoration can be related to the proper bonding of the resin cement to the composite. This study aimed to evaluate the microshear bond strength of two self-adhesive resin cements to composite resin. Material and Methods: Composite discs were subject to one of six different surface pretreatments: none (control), 35% phosphoric acid etching for 30 seconds (PA), application of silane (silane), PA + silane, PA + adhesive, or PA + silane + adhesive (n = 6). A silicone mold containing a cylindrical orifice ($1mm^2$ diameter) was placed over the composite resin. RelyX Unicem (3M ESPE) or BisCem (Bisco Inc.) self-adhesive resin cement was inserted into the orifices and light-cured. Self-adhesive cement cylinders were submitted to shear loading. Data were analyzed by two-way ANOVA and Tukey's test (p < 0.05). Results: Independent of the cement used, the PA + Silane + Adhesive group showed higher microshear bond strength than those of the PA and PA + Silane groups. There was no difference among the other treatments. Unicem presented higher bond strength than BisCem for all experimental conditions. Conclusions: Pretreatments of the composite resin surface might have an effect on the bond strength of self-adhesive resin cements to this substrate.
The purpose of this study was to compare the shear bond strengths to ground dentin surfaces of four dentinal bonding agents in 193 teeth. Various dentin surfaces treated with four dentin bonding agents were attached with two restorative composite resins. The effectiveness of the bonding were tested by the monitoring the shear bond strength. The shear bond strengths were measured after 2 hours and 24 hours after surface conditioning with four dentin bonding agents. Effects of EDTA, the additive illumination, and sealer treatments without primer on bond strength to dentin surfaces were assessed. In addition the effects of the thickness of specimens ranging from 0.65 mm to 1.95 mm and the ratio of catalyst and base paste on the bond strength of chemical cure composite resin were estimated. The shear bond strength was determined by testing specimens in the Instron universal testing machine (Model No. 1122) at a crosshead speed of 1.0 mm/min. Following condusions were drawn: 1. The highest mean shear bond strengths of chemical cure composite resin to dentin conditioning with dentin bonding agents aged 2 hours were obtained, and then that was decreased with time followed by EDTA treatment. 2. In light cure composite resin, the shear bond strength was increased following dentin conditioning with bonding agents with time, irradiation time and EDTA treatment except in SB group. 3. The thicker the composite resin specimen was, the less the shear bond strength in chemical cure composite resin was. 4. In light cure composite resin, there was a little change in shear bond strength following dentin conditioning with bonding agents. 5. In chemical cure composite resin, the shear bond strength was the highest in the ratio of 1/1 of catalyst and base part. 6. Without a dentin primer, shear bond strength to dentin conditioned only with UB sealer was the highest among four sealers in light cure composite resin.
Objectives: This study evaluated the effects of different surface conditioning methods on the bond strength of orthodontic brackets to glazed full-zirconia surfaces. Materials and Methods: Glazed zirconia (except for the control, Zirkonzahn Prettau) disc surfaces were pre-treated: PO (control), polishing; BR, bur roughening; PP, cleaning with a prophy cup and pumice; HF, hydrofluoric acid etching; AA, air abrasion with aluminum oxide; CJ, CoJet-Sand. The surfaces were examined using profilometry, scanning electron microscopy, and electron dispersive spectroscopy. A zirconia primer (Z-Prime Plus, Z) or a silane primer (Monobond-S, S) was then applied to the surfaces, yielding 7 groups (PO-Z, BR-Z, PP-S, HF-S, AA-S, AA-Z, and CJ-S). Metal bracket-bonded specimens were stored in water for 24 hr at $37^{\circ}C$, and thermocycled for 1,000 cycles. Their bond strengths were measured using the wire loop method (n = 10). Results: Except for BR, the surface pre-treatments failed to expose the zirconia substructure. A significant difference in bond strengths was found between AA-Z ($4.60{\pm}1.08MPa$) and all other groups ($13.38{\pm}2.57-15.78{\pm}2.39MPa$, p < 0.05). For AA-Z, most of the adhesive remained on the bracket. Conclusions: For bracket bonding to glazed zirconia, a simple application of silane to the cleaned surface is recommended. A zirconia primer should be used only when the zirconia substructure is definitely exposed.

Purpose: Rigid external distraction(RED) is a highly effective technique for correction of maxillary hypoplasia in patients with cleft or syndromic craniosynostosis. Despite many advantages of RED, it also has the problem of relapse as the conventional advancement surgery. Bicoronal approach, that is the common approach to gain access to the craniofacial skeleton, had some morbidity, such as hair loss, sensory loss, wide scar and temporal hollowing. We present our clinical experience of RED distraction with minimal invasive approach and early rigid fixation to overcome these disadvantages. Methods: A 27-year-old female patient with Crouzon's disease underwent Le Fort III osteotomy and RED device application through the minimal invasive direct skin incisions. After the latent period of 5 days, distraction was undertaken until proper convexity and advancement were obtained. During the rigid retention period, inflammation occurred on the right cheek, and proper conservative managements were done including continuous irrigation. To maintain the stability of distraction, early rigid fixation was undertaken on the osteotomy sites through another skin incisions. Preoperative and postoperative orthodontic treatments were performed. Serial photographs and cephalometric radiographs were obtained preoperatively, after distraction and 6 months after distraction. Results: The cephalometric analysis demonstrated postoperatively significant advancement of the maxilla and improvement of facial convexity. After 6-month follow-up period, the maxilla was stable in the sagittal plane and no relapse was found. Facial scars were not noticeable and other deformity and morbidity did not occur. Conclusion: This effective and stable technique will be a good alternative for the patients who need large amount of distraction and for adult patients with severe maxillary hypoplasia or syndromic craniosynostosis.
Objectives: Hydrogen peroxide ($H_2O_2$) surface treatment of fiber posts has been reported to increase bond strength of fiber posts to resin cements. However, residual oxygen radicals might jeopardize the bonding procedure. This study examined the effect of three antioxidant agents on the bond strength of fiber posts to conventional and self-adhesive resin cements. Materials and Methods: Post spaces were prepared in forty human maxillary second premolars. Posts were divided into five groups of 8 each: G1 (control), no pre-treatment; G2, 10% $H_2O_2$ pre-treatment; G3, G4 and G5. After $H_2O_2$ application, Hesperidin (HES), Sodium Ascorbate (SA) or Rosmarinic acid (RA) was applied on each group respectively. In each group four posts were cemented with Duo-Link conventional resin cement and the others with self-adhesive BisCem cement. Push-out test was performed and data were analyzed using 2-way ANOVA and tukey's post-hoc test (${\alpha}=0.05$). Results: There was a statistically significant interaction between the cement type and post surface treatment on push-out bond strength of fiber posts (p < 0.001, F = 16). Also it was shown that different posts' surface treatments significantly affect the push-out bond strength of fiber posts (p = 0.001). $H_2O_2$ treated posts (G2) and control posts (G1) cemented with Duo-link showed the highest ($15.96{\pm}5.07MPa$) and lowest bond strengths ($6.79{\pm}3.94$) respectively. Conclusions: It was concluded that $H_2O_2$ surface treatment might enhance the bond strength of fiber posts cemented with conventional resin cements. The effect of antioxidants as post's surface treatment agents depends on the characteristics of resin cements used for bonding procedure.
