Squamous cell carcinoma of tympanomastoid region – A rare and often misdiagnosed entity

Squamous cell carcinoma of the temporal bone and external auditory canal is a rare entity. We present a case of 62 year old male, with stage IV squamous cell carcinoma of tympanomastoid region. As the tumour was deemed unresectable, mass debulking was done and patient was given post-operative radiotherapy. The objective to report this case was to emphasise the importance of early diagnosis and prompt treatment for a better survival. A high index of suspicion is necessary as the initial presentation may mimic more common otologic conditions

Role of Silver Diamine Fluoride in Permanent Tooth Caries Management: A Narrative Review

Introduction: Silver Diamine Fluoride is vastly used in preventive and therapeutic management of deciduous dentition. It includes its utilization as a fissure sealant, for arresting carious lesions and as a pulp capping agent. However, its use in permanent dentition is limited. Hence, the present narrative review has been conducted in order to assess SDF use in permanent dentition. Methodology: Present review was conducted to evaluate role of SDF in permanent tooth caries management. A rigorous literature search was conducted utilizing various databases suchas PubMed, Scopus, Web of Science, Cochrane Database, and CTRI (Clinical Trial Registry - India). The search period was defined to be last 10 years, that is, from 1st January 2012 to 31st December 2021. Terminologies "Silver Diamine Fluoride," "SDF," "Permanent Dentition” were included. The terminologies were combined using Boolean Operations "AND" and "OR". Results:  7 studies were identified after following inclusion and exclusion criteria. The included studies were evaluated for study design, nature of trial along with its type, materials compared and procedure performed along with the results. Various uses of SDF were identified such as fissure sealant, in root caries management, in proximal or occlusal caries management along with its use as indirect pulp capping agent.  Conclusion: Although SDF use in primary dentition is widely acknowledged. Its use in permanent dentition is still limited. Hence more clinical trials need to be carried out for better understanding of this material

Observation of γγ → ττ in proton-proton collisions and limits on the anomalous electromagnetic moments of the τ lepton

The production of a pair of τ leptons via photon–photon fusion, γγ → ττ, is observed for the f irst time in proton–proton collisions, with a significance of 5.3 standard deviations. This observation is based on a data set recorded with the CMS detector at the LHC at a center-of-mass energy of 13 TeV and corresponding to an integrated luminosity of 138 fb−1. Events with a pair of τ leptons produced via photon–photon fusion are selected by requiring them to be back-to-back in the azimuthal direction and to have a minimum number of charged hadrons associated with their production vertex. The τ leptons are reconstructed in their leptonic and hadronic decay modes. The measured fiducial cross section of γγ → ττ is σfid obs = 12.4+3.8 −3.1 fb. Constraints are set on the contributions to the anomalous magnetic moment (aτ) and electric dipole moments (dτ) of the τ lepton originating from potential effects of new physics on the γττ vertex: aτ = 0.0009+0.0032 −0.0031 and |dτ| < 2.9×10−17ecm (95% confidence level), consistent with the standard model

Awareness and practice of patient’s oral care among critical care nurses in a rural tertiary care hospital

Background and aim: Oral care contributes significantly to the patients’ health outcome in a critical care unit. Nurses play a vital role in maintaining good oral health. However, there remains a dearth of literature regarding oral care practices among nurses workingin an Indian critical care unit. In this descriptive cross sectional study, we assessed the level of awareness and the existing practices of patients’ oral care among our critical care unit (CCU) nurses. Methodology: After obtaining approval from the institutional ethics committee, 64 CCU nurses, having work experience of atleast 6 months in the CCU, were enrolled in this descriptive cross sectional study. A self-structured questionnaire was used to assess the awareness and practice of the nurses. The data collected was analyzed using descriptive statistics and results were expressed as percentages.Result: Of the 64 nurses enrolled in the study, there were no dropouts. It was found that 62 (96.87%) nurses provided oral care to all the CCU patients. 60 (93.7%) nurses claimed that a standard oral care protocol has been provided to them. Documentation of the oral care was carried out by 54 (84.37%) nurses. Although 50% of the nurses had been trained to provide oral care, 54 (84.37%) nurses felt the need of fresh training. 60 (93.7%) nurses preferred using toothbrush in conscious patients. Chlorhexidine was the most commonly used solution. Bleeding, extubation and biting were among the few complications that they faced during routine oral care.Conclusion: Despite working in a rural set up with limited resources available, oral care was provided by most of the nurses. Following a standard protocol and documentation of the same, has helped maintain consistency in oral care of all critical care patients.Citation: Bhavika S, Shetti AN, Mustilwar R, Anshul S.
