Uso de membrana de celulosa oxidada post-gingivectomía en hiperplasia gingival inducida por fenitoína / Use of oxidized cellulose regenerated post-gingivectomy on ginigival hyperplasia induced by phenytoin

Introducción: La hiperplasia gingival es una condición benigna caracterizada por el aumento de volumen de la encía. Algunos fármacos, factores genéticos, aparatología y placa dentobacteriana son factores que pueden inducir esta condición. Objetivo: Devolver la anatomía a la encía brindando una mejor estética y permitiendo una óptima higiene oral. Material y métodos: Paciente masculino de 20 años de edad con antecedentes de fenitoína presenta aumento de volumen en la encía. Resultados: Se obtuvieron resultados estéticos y funcionales satisfactorios con el tratamiento quirúrgico y el uso de membrana de celulosa oxidada. Conclusión: En el manejo de la hiperplasia gingival es importante el enfoque no quirúrgico como control de placa dentobacteriana y medidas de higiene del mismo paciente (AU)

Introduction: Gingival hyperplasia is a benign condition characterized for the grown on the gingival volume. Some drugs, genetic, orthodontic and dental plaque are some factors that can induce this condition. Objective: To return the gingival anatomy, providing a better aesthetic allowing also good oral hygiene. Material and methods: A male 20 years of age with medical history of phenytoin display grown on the gingival volume. Results: Aesthetic and functional results were achieved with the surgical treatment and the oxidized cellulose membrane. Conclusion: In the gingival hyperplasia management is important de non-surgical approach, as dental plaque control and oral hygiene of the patient (AU)

Clinical Evaluation of Absorbable Regenerated Oxidized Cellulose in Lung Cancer Surgery / 中国肺癌杂志

BACKGROUND@#Thoracoscopic safe and effective hemostasis is an important condition for rapid rehabilitation of thoracic surgery. Placing hemostatic materials during surgery is a commonly used method in lung cancer laparoscopic surgery. Among them, resorbable oxidized cellulose is a commonly used hemostatic material. This research aims to observe the hemostatic effect of resorbable oxidized cellulose in lung cancer surgery.@*METHODS@#A retrospective analysis of 42 patients with thoracoscopic lung cancer undergoing radical surgery in the Department of Thoracic Surgery, First Affiliated Hospital of Zhejiang University School of Medicine from July 1, 2018 to December 1, 2018, and intraoperative use of regenerative oxidized cellulose to stop bleeding The clinical and pathological data were selected and the perioperative indicators were selected as the outcome events for statistical analysis.@*RESULTS@#The mean operative time was (120.5±57.3) min. The mean intraoperative blood loss was (26.8±21.6) mL. The average postoperative drainage volume was (513.6±359.5) mL. The average postoperative chest tube indwelling time was (2.6±1.2) d.@*CONCLUSIONS@#The use of absorbable regenerated oxidized cellulose in the radical operation of thoracoscopic lung cancer has a good hemostasis effect, and is suitable for hemostasis of wounds after lymph node dissection.

Research progress and application status of topical absorbable hemostatic / 医学研究生学报

Hemostatic agents play a crucial role in successful operations and the pre-hospital care of war wounds. Recently, hemostatic agents have become a hot topic in medicine,surgery and emergency medicine. The topical absorbable hemostatic agents are now the first choice of some clinical bleeding and war wounds owing to their features, such as flexible operation, high efficiency and wide application. A great variety of topical absorbable hemostatics have flooded the market. There are many differences existing among these hemostatics,including sources of material and the hemostatic mechanism,which makes it hard for clinicians to professionally se-lect the appropriate one.This review discusses the classification,hemostatic mechanism,clinical application,advantages and disadvan-tages of common topical absorbable hemostatics. Furthermore,we provide the basic theory for surgeons to choose suitable hemostatic a-gents at the right time.

A Case of Foreign Body Granuloma of the Posterior Mediastinum / 결핵

21-year-old male was admitted for evaluation of a mass shadow on chest film. On chest computed tomography showed 5 cm sized homogeneous low density based on the second thoracic vertebral body in the posterior mediastinum. The patient had been performed thoracic sympathectomy 6 months before admission and oxidized cellulose was used for hemostasis at that operation Surgical resection was performed and microscopic result was foreign body granuloma caused by oxidized cellulose. Oxidized cellulose is an absorbable sterile mesh and used to control capillary or venous bleeding. Although the manufacturer recommends its removal after hemostasis is achieved, in clinical practice it is usually left in situ to reabsorb spontaneously, usually with no untoward effect.
