All sets of paper currency produced by the government of Nepal were collected from four major sources (transporters, butchers, food sellers, and banks) where paper currency is widely used. The currencies used by public transport in Nepal (micro-buses) were found to be extremely contaminated with various pathogenic bacteria followed by the currency used by butchers and food sellers. These microorganisms could be one of the major causes of widely transmitting diseases in Nepal. Eight different pathogenic bacteria were isolated that are the known to be involved in transmitting various diseases in Nepal. A lot of people loss their life every year in Nepal due to the transmittance of diseases by these kind of bacteria. Use of paper money could be one of the major sources of transmittance of such diseases in Nepal that provides platform for the growth of such bacteria. Public awareness of using paper currency in circulation became essential for the safety in human health.

Background: Atrial fibrillation (AF) is the most common cardiac arrhythmia associated with high morbidity and mortality. AF treatment is guided by a patient–provider risk–benefit discussion regarding drug versus ablation or combination. Thermal ablation has a high rate of adverse events compared to pulsed field ablation (PFA). In this systematic review, we aimed to determine the safety and efficacy of PFA. Methods: The electronic search for relevant articles in English was completed in PubMed, PubMed Central, Cochrane library, Scopus, and Embase databases till July 2022. The screening was completed via the use of Covidence software. The risk of bias assessment and data extraction from the included studies was performed, and the narrative synthesis was performed accordingly. Results: A total of six studies were selected for review and 1897 patients receiving PFA were involved in these studies. Our review was focused on pulmonary vein isolation success, major adverse events, and arrhythmia recurrence. Successful pulmonary vein isolation (PVI) was completed in 100% of cases except in two studies. In one of them, six out of seven patients (86%) in the epicardial cohort had successful PVI. In the MANIFEST-PF survey, the acute PVI success rate was 99.9%. The major complications were rare and included pericardial tamponade, vascular complications requiring surgery, and stroke. The atrial arrhythmia recurrence was higher in the thermal group than in the PFA group (39% vs. 11%). Conclusions: The success rate of PVI by PFA is high, and major adverse events are low. PFA is found to decrease the recurrence of atrial arrhythmia compared to thermal ablation. Substantial randomized controlled trials (RCTs) are needed to validate the efficacy and safety of PFA over conventional methods.

Background Headache is a common neurological disorder, with a global prevalence of around 50%. It may affect people of any age, gender, education, socioeconomic status and occupation. Tension headache, migraine headache and cluster headache are commonly encountered headache types. The prevalence of headache problems is higher among medical students. This could potentially affect their academic performance and quality of life. The objective of this study is to find out the prevalence of headaches and their clinical characteristics among students of a medical college. Materials and methods An online, single-centre, cross-sectional study was conducted among undergraduate medical students in Nepal. Stratified sampling followed by a simple random sampling technique was adopted depending upon the academic years of students. For data collection, pre-tested semi-structured questionnaire was used. The data entry and analysis were done by using Statistical Package for the Social Sciences (IBM-SPSS), version-23. The prevalence of headache and its subtypes were calculated. All the clinical characteristics associated with headaches were also studied. Results The prevalence of headache disorder was 65 (26.86%), with tension headache (69.23%) being the commonest one. It was highest among fourth-year students (37.84%) followed by first-year students (33.33%). Anxiety/stress (75.40%) was the most common precipitating factor. This problem stopped most of the students (63.09%) from doing daily activities. More than half of them (53.85%) practised self-medication in case of non-resolution of pain, and non-steroidal anti-inflammatory drugs (NSAIDs) were frequently used. Conclusion Headache was fairly prevalent among medical students. Anxiety/stress in medical life has led to headaches in the majority of students. The headache disturbed their daily activities and promoted self-medication practice. So, this problem should be properly looked into and addressed in time by the concerned authority.

Subacute sclerosing panencephalitis (SSPE) is a late complication of childhood measles. It is characterized by a progressive decline in cognitive and motor functions, seizures, and eventually death. Although a combination of intrathecal interferon alpha (IFN-α) and daily oral isoprinosine has been reported to have a good outcome, there is no cure for this condition.We present a case of a 16-year-old male with SSPE who presented with progressive weakness, frequent loss of postural control, multiple episodes of generalized tonic-clonic seizures, and urinary incontinence. On exploration of his history, he had measles at the age of two months. Investigation showed increased serum measles antibody titer, high amplitude spikes in electroencephalogram (EEG), and high fluid-attenuated inversion recovery (FLAIR) signals on MRI of the brain consistent with probable SSPE. He was managed symptomatically until his condition got worse and he eventually passed away.
