ABSTRACT
In India, Chronic suppurative otitis media (CSOM) is a general public health issue leading to hearing loss which can be corrected surgically by Tympanoplasty. By applying predictors for a successful surgery the effectiveness of the surgery can be improved. In this study we aim to determine the usefulness of prognostic factors in predicting outcome of surgery for better patient compliance. 1. To compare MERI scores and saccharin test time in predicting graft uptake and hearing outcomes in Tympanoplasty surgery. A prospective study included all cases of mucosal type of CSOM of either sex according to the inclusion and exclusion criteria. Saccharin clearance time was used to assess Eustachian tube function and Pure Tone Audiometry has been done Pre-operatively to assess Hearing. Risk categories were assigned using MERI scoring chart and severity of disease assessed by otomicroscopy during surgery. Patients were post-operatively followed up to 6 months. Outcomes were assessed using Graft uptake, Hearing improvement and for recurrence of infection, compared with different categories of MERI and Saccharin time. The overall graft uptake was 96.6%. 100% successful graft uptake was seen among normal eustachian tube function. Hearing improvement after surgery may be predicted by saccharin and MERI test. Abnormal Saccharin test shows guarded prognosis in predicting the success of middle ear surgeries. Based on the MERI score and saccharin clearance time, hearing benefit and Surgical success can be assessed and patients can be counselled prior surgery regarding the expected outcome.
ABSTRACT
To analyse the outcome of transnasal endoscopic repair of CSF Rhinorrhea in a tertiary care centre. This is a retrospective study conducted on 81 patients who underwent CSF Rhinorrhea repair in a tertiary care hospital for a period of 11 years. Following confirmation of diagnosis using bio-chemical and radiological investigations, all patients underwent transnasal endoscopic repair of CSF Rhinorrhea using a multilayer graft. Patients were followed up for 6 months. The most common etiology in our study was spontaneous CSF rhinorrhea (60.49%) and subjects with BMI > 25.5 kg/m2 were more prone to it. Cribriform plate was found to be the most frequent site of leak in our study (58.02%), followed by fovea ethmoidalis (12.35%). Overall success rate was 96.30%. Transnasal endoscopic approach for cerebrospinal fluid rhinorrhea repair shows good success rate and also offers the advantages of better visualization and identification of site of leak, less complications, rapid postoperative recovery, and low recurrence rate. Transnasal endoscopic CSF Rhinorrhea repair has shown good results in terms of low recurrence rates and high patient satisfaction among other advantages. Hence this approach should be commonly used for CSF rhinorrhea repair by surgeons.
ABSTRACT
In present modern era, the outbreak of COVID-19 pandemic has created informational crisis. The public sentiments collected from different reflexions (hashtags, comments, tweets, posts of twitter) are measured accordingly, ensuring different policy decisions and messaging are incorporated. The implementation demonstrates intuition in to the advancement of fear sentiment eventually as COVID-19 approaches maximum levels in the world, by making use of detailed textual analysis with the help of required text data visualization. In addition, technical outline of machine learning stratification approaches are provided in the frame of text analytics, and comparing their efficiency in stratifying coronavirus tweets of different lengths. Using Naïve Bayes method, 91% accuracy is achieved for short tweets and using logistic regression classification method, 74% accuracy is achieved for short tweets.
ABSTRACT
The present study aimed at the production, purification and characterization of fibrinolytic nattokinase enzyme from the bacteria isolated from natto food. For the purpose, a fibrinolytic bacterium was isolated and identified as Bacillus subtilis based on 16S rDNA sequence analysis. The strain was employed for the production and optimization of fibrinolytic enzyme. The strain showed better enzyme production during 72nd h of incubation time with 50 degrees C at the pH 9. The lactose and peptone were found to be increasing the enzyme production rate. The enzyme produced was purified and also characterized with the help of SDS-PAGE analysis. The activity and stability profile of the purified enzyme was tested against different temperature and pH. The observations suggesting that the potential of fibrinolytic enzyme produced by Bacillus subtilis RJAS 19 for its applications in preventive medicines.
