Comparative Evaluation of the Effect of Six Different Low-Surface-Tension Vehicles on the Penetration of Modified Triple Antibiotic Paste in Dentinal Tubules: An In Vitro Study

Article

作者: Thote, Akshayprasad P ; Kibe, Aradhana N ; Nikhade, Pradnya P

Background Modified triple antibiotic paste (MTAP) helps in the elimination of microorganisms which is imperative for the success of endodontic therapy. The intracanal medicament powders must be mixed with vehicles for better handling and penetration in the root canals. The purpose of this study is to compare the effect of six low-surface-tension vehicles on the penetration of MTAP in dentinal tubules. Methodology The root apices of 60 single-rooted human mandibular premolars were resected to obtain 12mm length. After biomechanical preparation, intracanal medicaments were prepared by mixing with the six vehicles (Group 1- Bupivacaine, Group 2- Sodium ether lauryl sulfate, Group 3- Neosporin H, Group 4- Chlorhexidine gluconate, Group 5- Chitosan, and Group 6- Polyethylene glycol) with MTAP and Rhodamine B dye. Middle and apical transverse sections were scanned under a confocal laser scanning microscope. The data were statistically analyzed using the one-way ANOVA test and the level of significance was p<0.05. Results The maximum depth of penetration was seen in Group 2 (MTAP with sodium ether lauryl sulfate) followed by Group 5 (MTAP with chitosan), Group 4 (MTAP with chlorhexidine gluconate), Group 1 (MTAP with bupivacaine), and Group 6 (MTAP with polyethylene glycol), and the least penetration by Group 3 (MTAP with Neosporin H). The depth of penetration in the middle level was in the order of Group 2 followed by Group 4, Group 5, Group 3, Group 6, and Group 1. The depth of penetration in the apical level was in the order of Group 2 followed by Group 5, Group 1, Group 4, Group 6, and Group 3. The overall depth of penetration was significantly higher at the middle level than at the apical level. Conclusion Group sodium ether lauryl sulfate showed the maximum depth of penetration in both the middle and apical areas. The least depth of penetration in the middle area was seen in group bupivacaine and the apical area by group Neosporin H.

Autosensitization Triggered by Neosporin Use: A Unique Phenomenon

作者: Sragi, Zara ; Bathla, Jasdeep S ; Sugg, Kyle ; Tur, Komalpreet

Interface dermatitis is a type of dermatological insult to the dermo-epidermal skin junction. When this reaction causes secondary dermatosis that occurs distally on the body, it is known as autosensitization or autoeczematization. Here, we present the case of a middle-aged gentleman, with a medical history including human immunodeficiency virus, non-adherent to highly active antiretroviral therapy, initially presenting due to chronic recurring cellulitis on the left lower leg that had become progressively erythematous and tender to palpation. A few days later, he developed an intensely pruritic, papular rash on his face and chest. Following further investigation, he reported using Neosporin ointment on the leg rash prior to admission which had then caused allergic contact dermatitis. Ultimately, the patient was diagnosed with acute interface dermatitis due to Neosporin use, which led to a secondary autosensitization reaction involving his head, neck, and arms. This case illustrates the importance of thorough history taking and clinical suspicion to appropriately diagnose this phenomenon, further demonstrating the temporal association between allergic contact dermatitis and autosensitization.

Biliary antibiotics irrigation for E. coli-induced chronic proliferative cholangitis and hepatolithiasis: A pathophysiological study in rabbits

Article

作者: Cheng, Nan-Sheng ; Ma, Wen-Jie ; Wang, Jun-Ke ; Shi, Yu-Jun ; Hu, Hai-Jie ; Yang, Qin ; Li, Fu-Yu ; Wu, Zhen-Ru

BACKGROUND:

The gram-negative bacteria secreted endotoxin, Lipopolysaccharide (LPS), plays important roles in the formation and recurrence of hepatolithiasis and chronic biliary inflammation in patients of Southeast Asia. We aimed to elucidate the anti-inflammatory effect and mechanism of local antibiotics irrigation on chronic proliferative cholangitis (CPC) and hepatolithiasis.

METHODS:

Escherichia coli was injected into rabbit bile ducts to induce CPC. Rabbits were divided into sham operation (SO), povidone-iodine, Metronidazole plus chlorhexidine, ofloxacin, furacillin, Neosporin® G.U., and CPC groups. Local irrigation was performed for 28 days after CPC was established. Residual E. coli and LPS, and the expression of MCP-1, CD14, COX-2, VEGF, IL-6, NF-κB, TNF-α, Fas, TGF-β1, α-SMA, Collagen-I, β-glucuronidase, PKC, C-myc, and Mucin 5AC were assessed in bile duct tissues.

RESULTS:

The residual E. coli and LPS, and expression of MCP-1, CD14, COX-2, IL-6, NF-κB, TNF-α, Fas, TGF-β1, α-SMA, β-glucuronidase, PKC, C-myc, and Mucin 5AC in the SO, povidone-iodine, Metronidazole plus chlorhexidine, ofloxacin, and Neosporin® G.U. groups were significantly lower than those in the furacillin and CPC groups (P<0.05). VEGF and Collagen-I levels in the SO, povidone-iodine, metronidazole plus chlorhexidine, and ofloxacin groups were significantly lower than those in the furacillin, Neosporin® G.U., and CPC groups (P<0.05).

CONCLUSIONS:

LPS affects the pathophysiology of E. coli caused chronic proliferative cholangitis and hepatolithiasis recurrence. Local antibiotics irrigation could prevent chronic proliferative cholangitis and stones formation by decreasing LPS-induced proinflammatory and profibrotic cytokines release. Povidone iodine, metronidazole plus chlorhexidine, and ofloxacin were more effective than Neosporin® G.U. and furacillin.

奇迹抗生素？！PNAS | 新研究揭示常用抗生素新霉素鼻喷预防COVID-19与流感的潜力

人类呼吸道病毒感染往往会引起广泛的疾病，每年在全球范围内会造成大量的发病和死亡。近日，一篇发表在国际杂志Proceedings of the National Academy of Sciences上题为“Intranasal neomycin evokes broad-spectrum antiviral immunity in the upper respiratory tract”的研究报告中，来自耶鲁大学医学院等机构的科学家们通过研究发现，常见的非处方抗生素新霉素，可能成为抵御包括COVID-19和流感在内的多种呼吸道病毒感染的秘密武器。文章中，研究人员通过鼻腔给予动物模型新霉素（一种常见的抗生素）治疗，测试了其预防或治疗呼吸道病毒感染的有效性，随后他们发现，相同的鼻腔治疗方法（使用的是非处方药膏Neosporin）成功激活了健康人体内的干扰素刺激基因（ISGs，interferon-stimulated genes），迅速建立起一道强大的抗病毒防线。研究者Iwasaki说道，这是一项令人兴奋的研究发现，即一种廉价的非处方抗生素药膏能刺激机体激活一种抗病毒反应。这项研究支持了新霉素在抵御动物模型机体病毒性疾病中的关键预防和治疗性作用，并展示出了其能有效阻断病毒的感染和传播。呼吸道病毒每年会在全球影响数百万人的健康，截至2024年2月，因冠状病毒SARS-CoV-2所引起的COVID-19已经在全球引起了7.745亿例病例，导致690万人发生死亡；流感病毒每年在全球也会造成高达500万例严重病例，且会导致50万名患者发生死亡。常用抗生素新霉素或有望帮助抵御人类呼吸道病毒感染图片来源：Proceedings of the National Academy of Sciences (2024). DOI:10.1073/pnas.2319566121目前，大多数用于抵御呼吸道病毒感染的疗法（包括抗病毒药物、单克隆抗体和恢复期血浆疗法）都能通过静脉注射或口服，其重点能阻断当前感染的进展。研究人员表示，以鼻腔为中心的疗法或许有更好地机会在感染扩散到下呼吸道并引起严重疾病之前阻断感染。Dela Cruz博士说道，这项多学科合作的研究个工作结合了动物肺部感染建模实验和人类研究评估的重要见解，而且这种鼻腔内疗法在人体试验中同样引发了强烈的ISGs表达，预示着其作为预防措施的巨大潜力。本文研究结果表明，研究人员或许有望优化这种廉价的常用抗生素，从而有效预防病毒性疾病发生以及其在人群中的扩散，尤其是在资源非常有限的全球社区中，由于这种方法具有一定的宿主导向特性，因此，这种方法无论针对何种病毒或许都是有效的。综上，本文研究结果表明，新霉素或能被潜在用来作为一种宿主定向型抗病毒策略，从而预防和治疗人类呼吸道病毒感染。参考文献：Tianyang Mao, Jooyoung Kim, Mario A.

Novo Holdings invests in macrocycle startup Orbis as once-overlooked molecules get new interest

At long last, macrocycles are spinning into the spotlight. On Thursday, Orbis Medicines launched with €26 million in seed funding from European VC fund Forbion and Novo Holdings, the investment arm of Novo Nordisk’s parent foundation. The startup is focused on developing peptide drugs based on macrocycles, which are small chemical rings. Most macrocycle drugs, such as cyclosporine or a component of Neosporin, have been discovered in nature, but the molecules were for a long time left on the sidelines by drug developers because they had difficulty passing through membranes, an important quality for many pill-based medicines. However, recent advances in designing peptides have shown it’s possible to overcome that obstacle and have rekindled interest in the potential for macrocyclic medicines.
