Juvenile nasopharyngeal angiofibroma is a very rare, highly vascular, uncapsulated and locally invasive tumor. Recently a changing trend has been seen in its epidemiology, pathogenesis, diagnosis, medical management, pre-operative care, surgical management and postoperative care including radiotherapy. Study the changing trend basically in the north-eastern region of south-east Asia and its prospects. Retrospective study of patients presenting with JNA between the study period of 6 months (October 2014-March 2015 in the, Department of Otolaryngology and Head and Neck Surgery, Assam Medical College, Dibrugarh, Assam, India. Incidence in comparison to previous studies has increased. Eight patients were treated in the study period. Different approaches were used. Mean age of presentation was 18 years and more than 75 % of them were either Stage III or Stage IV. Different approaches like transpalatine, transpalatine along with transnasal, lateral rhinotomy and endoscopic surgery were used. The recurrence rate was 12.5 %. Surgery by transpalatine approach should be the choice of treatment. Endoscopic resection should be only used for Stage I or Stage II disease.
A new, simple, novel, accurate, precise, reliable, rapid and linear reverse phase high-performance liquid chromatography (RP-HPLC) method was developed and fully validated for simultaneous qualitative and quantitative estimation of Rosuvastatin (ROS), Clopidogrel (CLOP) and Aspirin (ASP) in bulk and pharmaceutical dosage form as per International Conference on Harmonization (ICH) guidelines. In the present work, good chromatographic separation was achieved by isocratic method using a Hypersil BDS C18 column (250 mm ×4.6, 5 μm) and a mobile phase consisting of KH2Po4 buffer pH-6.0: acetonitrile in the ratio 60:40, at a flow rate of 1 ml/min. The effluents obtained were monitored at 242nm with the UV-visible detector. The calibration curves obtained were linear (r2=0.999) over the concentration range of 7.5-22.5μg/ml and 1-3μg/ml for CLOP, ASP and ROS respectively. A run time of 7.0 minutes for each sample made it possible to analyze more than 200 samples per day. The retention time of ASP, CLOP and ROS was found to be 3.103 min, 4,277 min and 5.707 min respectively. The high recovery values (99%-101%) indicate a satisfactory accuracy. The low percent relative standard deviation (% RSD) values in the precision study reveal that the method is precise therefore the method can be used for routine monitoring of CLOP, ASP and ROS in industry in the assay of bulk drug and dosage form.

Synopsis
It is difficult to predict the future course and length of the ongoing COVID-19 pandemic, which has devastated healthcare systems in low- and middle-income countries (LMICs). Anesthesiology and critical care services are hard hit as many hospitals have stopped performing elective surgeries, staff and scarce hospital resources have been diverted to manage COVID-19 patients, and several makeshift COVID-19 units had to be set up. Intensive care units are overwhelmed with critically ill patients. In these difficult times, LMICs need to improvise, perform indigenous research, adapt international guidelines to suit local needs, and target attainable clinical goals.
Background: Epidemiological data on critically ill patients is crucial for understanding resource utilisation, gaps in quality of care and for supporting surveillance of endemic or emerging diseases. We report the epidemiology of critically ill patients from 17 intensive care units (ICUs) in Nepal using an established and standardised ICU registry. Methods: The ICU registry data is collected prospectively and includes data on case mix, severity, organ support and outcomes. We conducted a retrospective observational study with all adult (≥18 years) critically ill patients admitted to 17 ICUs in Nepal between September 2019 and September 2022. We report on case mix, treatment received, severity of illness, standardised mortality rates (SMR), discharge outcomes and ICU service activity. Descriptive statistics were used to report the findings. Results: Of the 18603 unique admissions, 14% were operative, with 35% emergency surgeries. Patients’ median age was 57 (IQR 40-71) and 59% were male. Hypertension and diabetes were common comorbidities and pneumonia accounted for 26% of all admissions. During the ICU stay, 39% of patients received mechanical ventilation, 29% received vasoactive medication and 10% received renal replacement therapy. The median predicted risk of death was 0.1 (IQR 0.1-0.3) using APACHE II and 0.2 (IQR 0.1-0.4) using eTropICS. The median SMR was 0.7 (IQR 0.5-0.8) and 0.8 (IQR 0.6-1.4) using eTropICS and APACHE II, respectively. Median length of stay was 4 days (IQR 2-7). Eighteen percent died in the ICU; of those alive at discharge, 12% went home, 84% went to another department and 3% went to another hospital. COVID-19 was the most common notifiable disease reported (12% of all admissions). Median ICU turnover was 9% (IQR 6-14) with bed capacity ranging from 43-278. Conclusions: These findings should guide forecasting and service planning to ensure ICUs can optimally care for critically ill patients in Nepal.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
