From an incidental lipoma to ileo-ileal intussusception in an adult: A case report.

INTRODUCTION AND IMPORTANCE: Intussusception in adults is rare, constituting a miniscule number of bowel obstruction pathologies. Clinical practice often considers it a last-resort diagnosis, as other causes of mechanical small bowel obstruction are more common. The diagnosis is a challenging one to make, as the "telescoping" motion of the intestines fluctuates in a waxing-and-waning nature. In adults, the etiology is predominantly a pathological lead point being either benign or malignant. When encountering an obscure cause of abdominal pain, intussusception caused by a small bowel lipoma may be the culprit. CASE PRESENTATION: In this unique case, we present the journey of a 55-year-old Emirati male who presented with severe abdominal pain, nausea and vomiting. The patient underwent various imaging modalities, initially an "incidental" lipoma finding in the terminal ileum until a diagnosis of ileo-ileal intussusception emerged in later imaging, given its unusual and fluctuating nature. Ultimately, a resection of the bowel segment with side-to-side anastomosis was done. CLINICAL DISCUSSION: This case report aims to illuminate the diverse clues and incidental findings encountered during our patient's path to a diagnosis. By exploring the elements of this patient's journey to a diagnosis, we aspire to aid future clinicians in navigating the challenges of identifying obstructive pathologies and considering intussusception as a rare yet crucial differential diagnosis. CONCLUSION: This case highlights the importance of a comprehensive approach to diagnosis and management of patients presenting with obstructive symptoms, incorporating both clinical insight and imaging modalities such as CT to ensure optimal patient outcomes. When confronting such an obscure cause of abdominal pain, intussusception caused by a small bowel lipoma may be the culprit.

A scoping review of the literature on the impact of the COVID-19 quarantine on the psychological wellbeing of medical students.

BACKGROUND: The goal of this study was to identify the nature and extent of the available published research on the impact of social isolation, on the psychological wellbeing of medical students, who had to quarantine due to the COVID-19 pandemic. METHODS: Design. Scoping review. SEARCH STRATEGY: The PRISMA-ScR (Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews), guideline, was used to structure this study. A search strategy was carried out across six bibliographic databases. PubMed, Embase, ERIC, Scopus, Cochrane Database of Systematic Reviews and Web of Science. The following search terms were used, "medical student*" AND "impact" AND "quarantine" AND "COVID-19". Searches were initially confined to articles published (excluding conference abstracts) between 1 January 2019- 21 August 2021 but updated in September 2022 with the original search terms expanded to include "isolation" or "lockdown" as well as "quarantine" and the period of search extended to 21 August 2022. A search of secondary references was conducted. Data from the selected studies were extracted, and the following variables recorded; first author and year of publication, country of study, study design, sample size, participants, mode of analysing impact of quarantine from COVID-19 on mental health and results of the studies. RESULTS: A total of 223 articles were identified in the original search in 2021 and 387 articles, in the updated search in 2022. Following the exclusion of duplicates and application of the agreed inclusion and exclusion criteria, 31 full-text articles were identified for the final review, most of which were cross sectional studies. Sample sizes ranged from 13 to 4193 students and most studies used a variety of self-administered questionnaires to measure psychological wellbeing. Overall, 26 of the 31 articles showed that quarantine had a negative impact on the psychological well-being of medical students. However, two studies showed no impact, and three studies showed an improvement. CONCLUSION: The evidence is growing. Quarantine because of the COVID-19 pandemic may have had a negative impact on the psychological wellbeing of medical students, but this is not certain. There is therefore a need for more studies to further evaluate this research question.

Polycystic Ovary Syndrome and Endometrial Cancer: A Scoping Review of the Literature on Gut Microbiota.

Gut dysbiosis has been associated with polycystic ovary syndrome (PCOS) and endometrial cancer (EC) but no studies have investigated whether gut dysbiosis may explain the increased endometrial cancer risk in polycystic ovary syndrome. The aim of this scoping review is to evaluate the extent and nature of published studies on the gut microbiota in polycystic ovary syndrome and endometrial cancer and attempt to find any similarities between the composition of the microbiota. We searched for publications ranging from the years 2016 to 2022, due to the completion date of the 'Human Microbiome Project' in 2016. We obtained 200 articles by inputting keywords such as 'gut microbiome', 'gut microbiota', 'gut dysbiosis', 'PCOS', and 'endometrial cancer' into search engines such as PubMed and Scopus. Of the 200 identified in our initial search, we included 25 articles in our final review after applying the exclusion and inclusion criteria. Although the literature is growing in this field, we did not identify enough published studies to investigate whether gut dysbiosis may explain the increased EC risk in PCOS. Within the studies identified, we were unable to identify any consistent patterns of the microbiome similarly present in studies on women with PCOS compared with women with EC. Although we found that the phylum Firmicutes was similarly decreased in women with PCOS and studies on women with EC, there was however significant variability within the studies identified making it highly likely that this may have arisen by chance. Further research pertaining to molecular and microbiological mechanisms in relation to the gut microbiome is needed to elucidate a greater understanding of its contribution to the pathophysiology of endometrial cancer in patients with polycystic ovarian syndrome.
