Comparison of effectiveness of 7.5% Povidone-iodine with 1% Clotrimazole ear drops and lignocaine in Otomycosis

Objectives: Our study is comparing the effectiveness of 7.5% Povidone-iodine with 1% Clotrimazole ear drops and lignocaine in the management of Otomycosis to highlight the importance of replacing conventional antifungals in routine practice. Setting: Department of ENT and Head and Neck Surgery, Holy Family Hospital, Rawalpindi, Pakistan. Study design: A prospective randomized control trial Methodology: This study was conducted for 12 months in our institute from July 2014 to June 2015. A total number of 148 patients with clinically diagnosed Otomycosis between the age group 15 to 55 years were studied. All patients with a clinical diagnosis of Otomycosis presenting with all four features of earache, itching, ear-blockage, and ear discharge in ENT OPD were included. Ear swabs were taken and sent for fungal culture. Patients were divided into A and B groups each comprising of 74 patients. Group A received 1% Clotrimazole ear drops and lignocaine and group B received 7.5% Povidone-iodine for 14 days after the results of cultures were received. At the end of 14 days, patients of both groups were compared based on the resolution of symptoms and signs. Results: At the end of 14 days, 32 out of 74 patients (43%) in group A receiving 1% Clotrimazole ear drops and lignocaine reported resolution of all symptoms, and 52 out of 74 patients(70%) showed complete resolution of all signs, while in group B,68 out of 74 patients(91%) showed complete resolution of symptoms and 69 out of 74 patients (93%) showed complete resolution of signs. Our study showed significant improvement in signs and symptoms of Otomycosis achieved by treatment with 7.5% Povidone-iodine compared to that achieved by 1% Clotrimazole ear drops and lignocaine. Conclusion: 7.5% Povidone-iodine is a more effective antifungal agent in the treatment of Otomycosis as compared to 1% Clotrimazole ear drops and lignocaine

Role of interventional radiology in the management of peripheral vascular malformations: a tertiary care center experience.

Peripheral vascular malformations (PVMs) represent a wide spectrum of vascular abnormalities occurring due to anomalous connections between arteries, veins, capillaries, and lymphatic channels at the microscopic level, in different combinations. They are rare and challenging to treat. Different operators may have different approaches based on their experience and expertise. Sclerotherapy either alone or in combination with embolization has been used as an independent method for the treatment of PVMs. Purpose The aim of this study is to assess the safety and efficacy of sclerotherapy and embolization, with or without surgery, for the treatment of peripheral vascular malformations, based on our approach. Materials and methods A retrospective review of all patients with PVMs treated in our interventional radiology department from 2011 to 2017 was carried out. Medical records, imaging, and follow-up notes were reviewed to evaluate the response to treatment and post-procedure complications. Results Thirty-four sessions were performed in 15 patients (eight male, seven female) with PVMs. Low-flow lesions were identified in 10, intermediate flow in one, and high flow in four patients. Sodium tetradecyl sulfate (STS) was used as the sclerotherapeutic agent in 10 (66.67%), glue with lipoidal in three (20.0%), and bleomycin in one patient (6.67%). Coils with PVA and a covered stent were used in one and a combination of coil, PVA, and gel foam was used in one patient. A marked response was seen in 11 and a partial response in four patients. One patient developed foot gangrene. Stent thrombosis was noted in one patient with no clinical consequences. Recurrence was seen in two patients, who were lost to follow up. Conclusion PVMs are complex lesions. Sclerotherapy with or without embolization is a safe and effective treatment modality, with clinical response approaching 100

Privacy preserving and serverless homomorphic-based searchable encryption as a service (SEaaS)

Serverless computing has seen rapid growth, thanks to its adaptability, elasticity, and deployment agility, embraced by both cloud providers and users. However, this surge in serverless adoption has prompted a reevaluation of security concerns and thus, searchable encryption has emerged as a crucial technology. This paper explores the Searchable Encryption as a Service (SEaaS) and introduces an innovative privacy-preserving Multiple Keyword Searchable Encryption (MKSE) scheme within a serverless cloud environment, addressing previously unmet security goals. The proposed scheme employs probabilistic encryption and leverages fully homomorphic encryption to enable operations on ciphertext, facilitating searches on encrypted data. Its core innovation lies in the use of probabilistic encryption for private multi-keyword searches. To validate its practicality, we deploy the scheme on the public cloud infrastructure, “Contabo,” and conduct rigorous testing on a real-world dataset. The results demonstrate that our novel scheme successfully preserves the privacy of search queries and access patterns, achieving robust security. This research contributes to the field of serverless cloud security, particularly in the context of searchable encryption, by providing a refined solution for safeguarding data while maintaining usability in a serverless computing landscape

Green Synthesized Silver Nanoparticles as Potent Antifungal Agent against Aspergillus terreus Thom

Medicinal plants are composed of a rich pool of biomolecules and have been increasingly recognized for their antimicrobial properties; however, increasing concerns have been put on the bioavailability features. Thus, this study is aimed at exploring the synthesis and characterization of silver nanoparticles synthesized by Chenopodium album L. leaf extract and assessing the antifungal activity against Aspergillus terreus Thom. Plant extract was prepared in methanol to synthetize silver nanoparticles, which were then characterized by Scanning Electron Microscopy (SEM), UV-Visible spectroscopy, and particle size analysis. UV-Visible analysis indicated maximum absorption at 378 nm, and an average particle size was observed as 25.6 nm. Oval to hexagonal shape was observed by SEM. Antifungal activity of silver nanoparticles (1, 1.5, 2, 2.5, 3, and 3.5%) was addressed against A. terreus biomass. At 3.5%, silver nanoparticles revealed to be highly effective, leading to 92% retardation in fungus growth. In next phase, various organic fractions, viz., chloroform, n-butanol, n-hexane, and ethyl acetate, were obtained from plant methanol extract, and the corresponding silver nanoparticles were prepared. These fractions were also assessed for antifungal activity, and n-hexane fraction led to 64% inhibition in A. terreus biomass. Following gas chromatography-mass spectrometry (GC-MS), 18 compounds were identified, namely, 1,3-cyclopentadiene-5-(1 methylethylidene and o-xylene), ethyl benzene, octadecane, nonane, decane, 2-methylheptane, n-hexadecane, 2-methylheptane, and eicosane, along with carbonyl compounds (4,4-dimethyl-3-hexanone) and phenols, like stearic acid, propionic acid hydrazide, and 2,4-di-T-butylphenol. These findings proved that C. album silver nanoparticles are highly effective against A. terreus.N.C.-M. acknowledges the Portuguese Foundation for Science and Technology under the Horizon 2020 Program (PTDC/PSI-GER/28076/2017)

Drug-Induced Hand-Foot Syndrome in Cancer Patients Receiving Capecitabine in A Tertiary Care Hospital

Objective: To determine the frequency of hand-foot syndrome and associated factors among patients receiving Capecitabine for the management of cancer in a tertiary care setting. Study Design: Cross-sectional study. Place and Duration of Study: Oncology Department Combined Military Hospital, Rawalpindi Pakistan from Dec 2020 to May2021. Methodology: One hundred patients with malignant conditions taking Capecitabine for more than two weeks were included in the study. A detailed relevant dermatological examination was carried out on all the patients to diagnose hand-foot syndrome based on the National Cancer Institute Common Terminology Criteria for Adverse Events Version 4.0 Grading of Hand-Foot Syndrome. Results: Out of 100 cancer patients using Capecitabine for more than two weeks included in the study. Sixty-eight showed the presence of hand-foot syndrome, while 32 did not show any features of hand-foot syndrome. Combination treatment was statistically significantly associated with hand-foot syndrome among the patients included in our study (p-value<0.001). Conclusion: Hand-foot syndrome was a common side effect seen in patients managed with Capecitabine for their cancerous condition. Patients using other chemotherapeutic agents along with Capecitabine were more at risk of having hand-foot syndrome than those taking Capecitabine alone

Implementation and effectiveness of non-specialist mediated interventions for children with Autism Spectrum Disorder: A systematic review and meta-analysis

INTRODUCTION: In recent years, several non-specialist mediated interventions have been developed and tested to address problematic symptoms associated with autism. These can be implemented with a fraction of cost required for specialist delivered interventions. This review represents a robust evidence of clinical effectiveness of these interventions in improving the social, motor and communication deficits among children with autism. METHODS: An electronic search was conducted in eight academic databases from their inception to 31st December 2018. A total of 31 randomized controlled trials were published post-2010 while only 2 were published prior to it. Outcomes pertaining to communication, social skills and caregiver-child relationship were meta-analyzed when reported in \u3e 2 studies. RESULTS: A significant improvement was noted in child distress (SMD = 0.55), communication (SMD = 0.23), expressive language (SMD = 0.47), joint engagement (SMD = 0.63), motor skills (SMD = 0.25), parental distress (SMD = 0.33) parental self-efficacy (SMD = 0.42) parent-child relationship (SMD = 0.67) repetitive behaviors (SMD = 0.33), self-regulation (SMD = 0.54), social skills (SMD = 0.53) symptom severity (SMD = 0.44) and visual reception (SMD = 0.29). CONCLUSION: Non-specialist mediated interventions for autism spectrum disorder demonstrate effectiveness across a range of outcomes for children with autism and their caregivers

Transition metal doped CeO2 for photocatalytic removal of 2-chlorophenol in the exposure of indoor white light and antifungal activity

Besides natural sunlight and expensive artificial lights, economical indoor white light can play a significant role in activating a catalyst for photocatalytic removal of organic toxins from contaminated water. In the current effort, CeO2 has been modified with Ni, Cu, and Fe through doping methodology to study the removal of 2-chlorophenol (2-CP) in the illumination of 70 W indoor LED white light. The absence of additional diffractions due to the dopants and few changes such as reduction in peaks’ height, minor peak shift at 2θ (28.525°) and peaks’ broadening in XRD patterns of modified CeO2 verifies the successful doping of CeO2. The solid-state absorption spectra revealed higher absorbance of Cu-doped CeO2 whereas a lower absorption response was observed for Ni-doped CeO2. An interesting observation regarding the lowering of indirect bandgap energy of Fe-doped CeO2 (∼2.7 eV) and an increase in Ni-doped CeO2 (∼3.0 eV) in comparison to pristine CeO2 (∼2.9 eV) was noticed. The process of e-– h+ recombination in the synthesized photocatalysts was also investigated through photoluminescence spectroscopy. The photocatalytic studies revealed the greater photocatalytic activity of Fe-doped CeO2 with a higher rate (∼3.9 × 10−3 min-1) among all other materials. Moreover, kinetic studies also revealed the validation of the Langmuir-Hinshelwood kinetic model (R2 = 0.9839) while removing 2-CP in the exposure of indoor light with a Fe-doped CeO2 photocatalyst. The XPS analysis revealed the existence of Fe3+, Cu2+ and Ni2+ core levels in doped CeO2. Using the agar well-diffusion method, the antifungal activity was assessed against the fungus M. fructicola and F. oxysporum. Compared to CeO2, Ni-doped CeO2, and Cu-doped CeO2 nanoparticles, the Fe-doped CeO2 nanoparticles have outstanding antifungal properties
