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.

Systemic Lupus Erythematosus (SLE) is a chronic auto-immune disorder with the involvement of multiple organ systems. It is more common in females. Here, we present a case of 12-year-old female, known case of SLE with lupus nephritis, presenting with neuropsychiatric symptoms. She was under steroids as well for a few weeks due to flare-up of symptoms prior to that. Due to this, there was a diagnostic dilemma between lupus psychosis and steroid induced psychosis. Approximately one third to half of the patients may have neurological involvement in Systemic Lupus Erythematosus. However, neuropsychiatric symptoms in them could be due to corticosteroids, which are frequently used in treatment. There are no definitive and easily available laboratory markers to distinguish these two aetiologies. Systemic Lupus Erythematosus patients, who are on steroids, with neuropsychiatric features should be assessed adequately. As there are no specific guideline and biomarkers to distinguish between these two, meticulous evaluation is necessary for appropriate management.

Amyand hernia is an accidental finding that occurs in 0.19–1.7% of patients with inguinal hernia, with children being more commonly affected than adults. However, the management depends on the guidelines given by Losanoff and Basson. A 62-year-old male presented with complaints of progressive swelling in the right inguinal region without any clinical spectrum of bowel obstruction or strangulation. Examination revealed a right-sided indirect inguinal hernia with positive Ziemann technique. Open hernioplasty revealed an appendix within a hernia sac and was found to be adhered to the surrounding structure with a fibrotic band. According to the Losanoff and Basson protocol, the patient had an appendectomy and an open mesh repair with polypropylene mesh without any post-operative complications. Amyand hernia are often predominantly present in children, with a rare presence in the elderly. Pre-operative clinical diagnosis remains a challenge, and the management depends upon the Losanoff and Basson protocol. Appendectomy of the normal appendix within the hernia sac is often recommended to prevent the sequelae (appendicitis, rupture) following manipulation during hernioplasty. Amyand's hernia is a rare clinical entity and difficult to diagnose due to its uncomplicated presentation. Nevertheless, the progress of appendix inflammation, the possibility of abdominal sepsis, and co-morbidities should all be taken into consideration when deciding how to manage individual patients.

Introduction and importance: Obturator hernia is an infrequent clinical entity of abdominal wall hernia, accounting for an incidence rate ranging from 0.073 to 2.2% of all hernias and being responsible for 0.2–1.6% of all cases of mechanical intestinal obstruction. The computed tomography (CT) scan, as an imaging modality, is critical in improving the diagnostic rate of obturator hernia. Case presentation: The authors herein report an 87-year-old thin male patient with a known history of chronic obstructive pulmonary disease who presenting with complaints of abdominal pain for 3 days and constipation for 2 days, as well as one episode of vomiting without any features of peritoneal irritation, which was diagnosed early as a right-sided obturator hernia via CT and managed with exploratory laparotomy with hernia reduction and polypropylene mesh repair. Discussion: Obturator hernia is a rare surgical phenomenon with a varied clinical spectrum, ranging from asymptomatic to presenting as intestinal obstruction. The CT scan plays a critical role in the detection of obturator hernias, which ameliorates the possible significant postoperative morbidity and mortality. Conclusion: This report demonstrates that a high index of suspicion combined with CT imaging aids in early diagnosis and management, thus overcoming the reluctant morbidity.

Esophagitis caused by Herpes Simplex virus is a well-recognized opportunistic infection in the immunocompromised or severely ill host. However, it is uncommon in otherwise immunocompetent host. It usually responds well to a course of acyclovir. We report a case of young female without any other immunocompromised state who presented with severe dysphagia. She was diagnosed endoscopically and later with histopathology and recovered well after a course of acyclovir.

Background: Among the various causes for dyspepsia in patients presenting to the gastroenterology department, Helicobacter pylori is the most common etiological agents. Here, we explore the prevalence of Helicobacter pylori infection, particularly, in dyspeptic patients and different endoscopic findings in such patients. Methods: We conducted a simple observational study in the gastroenterology department of a tertiary care center of Nepal. The Helicobacter pylori was detected using rapid urease test and endoscopic findings were collected from gastroduodenoscopy unit. The obtained data was analyzed using Statistical Package for Social Sciences (IBM-SPSS), version 22. Results: The overall prevalence of Helicobacter pylori infection in dyspeptic patients in our center was found to be 0.329 (0.259 – 0.406) at 95% Confidence Interval (CI). There was significant association of Helicobacter pylori infection with alcohol history (12 [52.17] vs 44 [29.93], p = 0.035) and endoscopic findings of duodenal ulcer (3, 100%) followed by gastritis (29, 50.88%). Conclusions: Amidst various etiology for dyspepsia, Helicobacter pylori was still prevalent at our center. However, considering the variability of its prevalence due to factors like alcohol history, more comprehensive studies are needed to estimate actual proportion in patients presenting with dyspeptic symptoms.
