ABSTRACT
RESUMEN: La presencia de defectos en el esmalte puede afectar negativamente la autoestima de pacientes jóvenes, haciendo muchas veces necesario realizar un tratamiento estético. El tratamiento con resinas infiltrantes, permite obtener resultados estéticos sin realizar remoción del tejido dentario. Sin embargo, en casos de defectos de esmalte con fracturas post-eruptivas, la resina infiltrante por sí sola, no permite obtener un resultado óptimo. El presente reporte utiliza la combinación de resina infiltrante con resina compuesta directa para obtener resultados estéticos. De esta manera, al infiltrar primero, se mejora el aspecto estético de la lesión y también las características adhesivas del esmalte defectuoso, para posteriormente restaurar el contorno perdido aplicando una delgada capa de resina compuesta de translucidez media.
ABSTRACT: The presence of enamel defects can affect negatively the self-esteem of young patients, making it necessary to carry out an aesthetic treatment. Resin infiltration treatment provides aesthetic results without the necessity of removing the defective dental tissue. However, in cases of enamel defects with post-eruptive fractures, the treatment with resin infiltration by itself does not achieve optimal results. This report uses the combination of resin infiltration with direct resin composite to obtain an aesthetic result. This way, by first infiltrating, the aesthetic appearance of the lesion is improved, as well as the adhesive characteristics of the enamel, and subsequently the contour is restored by applying a thin layer of medium translucency resin composite.

Hepatic echinococcosis is a worldwide parasitic disease caused by Echinococcus.It divided into two parts,cystic echinococcosis and alveolar echinococcosis.Surgical operation is the main treatment method and with huge trauma and risk.The treatment methods for hepatic echinococcosis became diverse with the development of minimally invasive treatment.High intensity focused ultrasound is an effective and safety treatment method for hepatic echinococosis.This paper introduced high intensity focused ultrasound treatment therapy in hepatic hydatid disease systematically.Introduced the principle,safety and efficacy,indications and therapeutic advantages,complications and shortcomings,through these aspects we could know about high intensity focused ultrasound treat for hepatic echinococcosis clearly.This paper introduced the prospect of high intensity focused ultrasound treatment in hepatic echinococcosis and affirmed the therapeutic value about it.This paper introduced a new method of minimally hvasive treatment,which is helpful for clinical treatment.
ABSTRACT
Objective To analyze the clinical effects of sinus tarsi approach with minimal-inva-sive percutaneous screw fixation of calcaneal fractures. Methods From February 2014 to July 2015,28 ca-ses of calcaneal fracture patients(Sanders Ⅰ ~ Ⅲ)were treated with minimal-invasive percutaneous screw fixation via sinus tarsi approach in our department. There were 18 males and 10 females with age ranging from 16 to 68 years(mean,32 years). According to the classification of Sanders,six cases were classified as Type I,twelve as Type Ⅱ,and ten as Type Ⅲ. The Bohler angle and Gissane angle were compared be-fore and after operation. Clinical results were evaluated with the Maryland foot scoring system. Results All the patients were followed up for 14 to 20 months(mean,15. 5 months). Anatomic or almost anatomic reduction was achieved in all patients according to the results of postoperative images. All fractures healed,and the healing time ranged from 4 to 7 months(average,5. 3 months). There was no wound infec-tion,necrosis or bone nonunion. According to the Maryland foot scoring system,16 cases were defined as excellent,10 cases as good,and 2 cases as poor. The good and excellent rate was 92. 8% . Conclusion For calcaneal fractures,sinus tarsi approach with minimal-invasive percutaneous screw fixation has the ad-vantages of small trauma,safe operation,limited complication,and stable fixation,which is a satisfactory clinical treatment.
ABSTRACT
OBJECTIVE: This study aimed to evaluate the outcome of benign vocal cord tumors treated using a laryngeal endoscopy under low temperature‑controlled radiofrequency and to elucidate the application of a dynamic laryngoendoscopy in the operation. MATERIALS AND METHODS: 85 patients with benign vocal cord tumors were treated by laryngeal endoscopy under low temperature‑controlled radiofrequency from September 2011 to October 2013. A XION electronic dynamic laryngoendoscopy (Germany) was used to observe curative effects 3 months after operation. Wave images were recorded with larynx‑wave recording software to analyze tumor characteristics. RESULTS: Among the 85 patients, 81 showed smooth surface of operation wounds without any residue. The mucosal wave was also basically normal. Sound was generally recovered after 1–3 months. Three cases presented improved pronunciation function after the operation, whereas 1 patient with residual tumor at the front of vocal chords underwent another operation after 6 months.CONCLUSION: Low temperature‑controlled radiofrequency exhibited many advantages, including minimal trauma, minimal bleeding, high safety, and few complications. Moreover, treatment of benign vocal cord tumors with a laryngeal endoscopy presented satisfactory outcomes. Therefore, this technology has broad application prospects.

Objective To explore the therapeutic efficacy of percutaneous compression plate internal fixation in the treatment for elder-ly patients with interchanteric fractures. Methods All 17 patients with interchanteric fractures from March 2012 to January 2013 were trea-ted with percutaneous compression plate internal fixation(Fracture classification:type A1. 2 with 3cases,A1. 3 with 4cases,A2. 1 with 6 ca-ses,A2. 2 with 3 cases,A2. 3 with 1 case). After operation,the patients did functional exercises at the early stage. Then the efficacy were e-valuated and analyzed. Results Operation time was 30~80 min,with average time 50 min, blood loss was (40~100) mL,with average volume 60 mL,time of X-ray exposure was 12~22 s,with average time 20 s. All 17 patients were followed up for 3~18 months. Postoperative function were evaluated according to Harris Hip Score,15 cases were excellent,and 2 cases were good,the excellent and good rate was 100%. Conclusion Percutaneous compression plate internal fixation is suitable for the elderly patients of interchanteric fractures,with shorter oper-ation time,less blood loss,reliable fixation and less complications.
ABSTRACT
The consequences of osteoporotic vertebral compression fractures are pain, progressive vertebral collapse with resultant kyphosis, and systemic manifestations. Minimally invasive stabilization procedures such as vertebroplasty and balloon kyphoplasty have been introduced to treat for refractory pain due to these fractures. Vertebroplasty and kyphoplasty are new alternatives for the treatment of osteoporotic vertebral compression fractures. Both methods stabilize the fractured vertebra with polymethylmethacrylate cement to relieve pain and allow immediate mobilization. Kyphoplasty is an extension of vertebroplasty that uses an inflatable bone tamp to restore the vertebral body height while creating a cavity to be filled with bone cement. A large proportion of subjects had some pain relief both in vertebroplasty and kyphoplasty. Vertebral height restoration was possible using kyphoplasty and for a subset of patients using vertebroplasty. Cement leaks occurred in both groups but, the incidence of cement leakage in kyphoplasty is lower than that of the vertebroplasty. Vertebroplasty and kyphoplasty are safe and effective procedures. Good short-term results have been reported following both vertebroplasty and kyphoplasty for the painful osteoporotic vertebral fractures. Severe complications result from bone cement leakage into the spinal canal or the vascular system have been reported but the incidence was very rare. Both vertebroplasty and kyphoplasty offer therapeutic benefit significantly reducing pain and improving mobility in patients with vertebral fracture without significant differences between groups in term of quality. While early results are promising, more research is needed to better understand the log-term effects of both procedures on the human spine.

The incidence of early gastric cancer (EGC) has increased to over 50% in Korea and Japan due to rapid advances in diagnostic instrumentation and increased use of mass screening. Considering the excellent prognosies of EGC patients, the quality of life of these patients after treatment has recently been emphasized. For the better quality of life, laparoscopic surgery has emerged as an alternative therapy for EGC patients. Since Kitano et al. first performed laparoscopy-assisted distal gastrectomy (LADG) for early gastric cancer in 1991, it has been performed worldwide, especially in Japan and Korea. A number of reports have presented the excellent short term outcomes; less pain, better cosmetics, faster recovery, and shorter hospital stay. However, there is little evidence of the oncological outcome of laparoscopic gastrectomy as a treatment modality for gastric cancer. Multi-center randomized controlled trials of laparoscopic versus open gastrectomy are needed to establish the future role of laparoscopic surgery in the treatment of patients with gastric cancer.
