Denture disinfection by microwave irradiation: A randomized clinical study

Objective

This study evaluated the clinical effectiveness of two exposure times of microwave irradiation on the disinfection of complete dentures.

Methods

Biofilm samples were collected from dentures of 30 patients, who were randomly divided into two experimental groups of 15 subjects each: Group 1—patients had their maxillary denture microwaved for 3 min (650 W); Group 2—patients had their maxillary denture microwaved for 2 min (650 W). Denture biofilm samples were taken with swabs, before (left side surfaces) and after (right side surfaces) microwave irradiation. All microbial material was plated on selective media for Candida spp., Staphylococcus spp., mutans streptococci and a non-selective media. After incubation (48 h/37 °C), the number of colony-forming units (cfu/mL) was counted. Microorganisms which grew on selective media were identified using biochemical methods. The data were statistically analyzed by Kruskal–Wallis test, followed by Dunn's post-test (α = 0.05).

Results

Microwave irradiation for 3 min (Group 1) resulted in sterilization of all dentures evaluated. After microwave irradiation for 2 min (Group 2), a significant decrease in Candida spp. (P = 0.0062), Staphylococcus spp. (P = 0.0178), mutans streptococci (P = 0.0047) and non-identified species (P < 0.0001) was achieved in comparison with the cfu/mL obtained before irradiation. The colonies grown after 2 min of microwave irradiation were identified as Candida albicans, non-aureus Staphylococci and Streptococcus mutans.

Conclusion

Microwave irradiation for 3 min may be a potential treatment to prevent cross-contamination.

大学生蠕形螨感染情况调查

目的:了解在校大学生蠕形螨感染情况,探讨蠕形螨感染与面部皮肤疾病的关系.方法:采用透明胶带粘贴法对638名在校大学生进行蠕形螨检查,同时对面部皮肤状况进行调查.结果:在校大学生蠕形螨感染率为17.55%,且男性(22.05%)显著高于女性(14.58%);毛囊蠕形螨面部感染率(65.18%)高于皮脂蠕形螨(24.11%);有面部皮肤疾病者蠕形螨感染率明显高于面部皮肤正常者.结论:本校大学生蠕形螨感染较为普遍,感染多为毛囊蠕形螨;蠕形螨感染是痤疮、酒渣鼻等皮肤疾病的致病因素之一.     

新冠肺炎疫情防控期间急诊腹部多发伤一体化救治管理及对策

探讨新型冠状病毒肺炎（NCP）疫情期间急诊科接诊腹部多发伤的安全防护管理及高效救治流程及对策。制定规划急诊科安全防护管理方案及腹部多发伤一体化救治方案,制定急诊科疫情防控标准管理流程及腹部多发伤一体化救治管理流程,在把好预防NCP“四个安全防护管理环节”上,做到确保病区安全,避免院内交叉感染的发生;通过实施以上救治措施,提高了救治效果、降低了死亡率。按照全防护管理流程及腹部多发伤一体化救治管理流程保证了NCP疫情期间急诊科病区安全、医护人员安全、患者和陪护家属安全,无疫情不良事件发生,同时显著提高了腹部多发伤患者的抢救成功率。     

腹股沟疝无张力修补术后补片感染的外科处理

目的探讨腹股沟疝无张力修补术后补片感染的原因与外科处理方法。 方法回顾性分析2010年1月至2019年1月南京医科大学附属南京医院收治的12例腹股沟疝无张力修补术后补片感染患者的临床资料,研究其感染的原因并总结外科处理的方法。 结果12例患者均再次手术取出感染补片,患者全部治愈。术后随访9~36个月,无疝复发。 结论补片感染是腹股沟疝无张力修补术的严重并发症,一旦发生需再次手术取出补片,治疗不增加术后疝复发率。     

How to advise a patient who wants a tattoo?

Tattooing and permanent make-up have become mainstream procedures. Many factors play a role in the final outcome of a tattoo and the satisfaction of the customer. The technical and artistic skills of the tattooist will determine the esthetic result and will help to guide the customers in their decision and choice of the tattoo. Although tattooing is by many considered as safe one should be are aware of the risks of complications related to this body modification technique. Some customers have a medical problem and some doubt about the safety of the procedure. People with increased risk of adverse events often seek medical advice prior to decide to get a tattoo or PMU. Physicians should not only be informed about the medical history of their patients but also have some basic knowledge of the practice of tattooing and the effects this procedure can exert on the skin and on the health condition of the patient. Contraindications and special precautions with regard to skin diseases and specific systemic conditions will be addressed in this article.     

Systemic diseases and infections,anecdotal complications and oddities associated with tattooing

Complications associated with tattoos are mostly of cutaneous origin. They include chiefly ink allergy, local infection, benign tumors or malignant lesions and elective localization of various dermatoses. Tattoo-related systemic diseases and infections have more rarely been described, the most common being sarcoidosis and hepatitis C. However, unusual associations have also been reported, even though they may be anecdotal or likely unrelated with the procedure.
