RESUMO
We describe a case of non-alcoholic steatohepatitis detected incidentally during laparoscopic Roux-en-Y gastric bypass (LRYGBP). A 51-year-old female patient was scheduled for elective LRYGBP. Her weight was 144.9 kg and her body mass index was 56. Liver function tests showed mild elevation in alanine transaminase. The patient had a history of hypertension and insulin resistance and had no history of alcohol abuse. During LRYGBP, the gross appearance of the liver resembled metastatic lesions but the histology confirmed the diagnosis of non-alcoholic steatohepatitis. The appearance of the liver necessitated taking biopsies, which showed Von Meyenburg complexes and moderate macrovesicular steatosis. This patient made an uneventful recovery and was discharged 2 days postoperatively.

Individuals who are overweight or suffering from obesity are in a chronic state of low-grade inflammation, making them particularly susceptible to developing severe forms of respiratory failure. Studies conducted in past pandemics link obesity with worse health outcomes. This population is thus of particular concern within the context of the COVID-19 pandemic, considering the cessation of obesity management services. This systematic review highlights [1] the reciprocal link between the obesity and COVID-19 pandemics, [2] obesity as a risk factor for more severe disease in past pandemics, [3] potential mechanisms that make individual's suffering from obesity more susceptible to severe disease and higher viral load, and [4] the need to safely resume bariatric services as recommended by expert guidelines, in order to mitigate the health outcomes of an already vulnerable population.

AIM: This review provides a comprehensive overview of more than 100 of the most cited studies in general medical journals and evaluates whether citations predict the quality of a scientific article. BACKGROUND: The number of citations is commonly used as a measure of the quality and impact of a scientific article. However, it is often criticised that the number of citations is in fact a poor indicator of the true quality, as it can be influenced by different factors such as current trends. METHODS: This review was conducted in line with the PRISMA guidelines. The Journal Citation Report (JCR) within Incites allowed the evaluation and comparison of articles, published in general medical journals, using far-reaching citation data drawn from scholarly and technical journals and conference proceedings. All steps of the review were performed in duplicate and conflicts were resolved through consensus. RESULTS: The 100 most cited articles published from 1963 until the end of 2018 were identified. The number of citations ranged from 4012 to 31853. Most of the articles were published in the 2000's, followed by the 1990's, 1980's, 1970's and 1960's, respectively. All of the articles were published in five journals. There were 50 studies at level II, 28 at level V, 10 at level IV, 7 at level III, and 5 at Level I. CONCLUSION: This systematic review provides an overview of the most cited articles, published in general medical journals. The number of citations provides an indication of the quality of evidence. However, researchers and clinicians should use standardized assessment tools rather than solely rely on the number of citations in order to judge the quality of published articles.

Ward rounds are widely considered an underutilized resource with regard to medical education, and therefore, a project was undertaken to assess if the initiation of "trainee-centered ward rounds" would help improve the confidence, knowledge acquisition, and workplace satisfaction of junior doctors in the clinical environment. Data were collated from junior doctors, registrar grade doctors, and consultants working in the delivery suite at Luton and Dunstable University Hospital in Luton over a 4-week period in March-April 2013. A review of the relevant literature was also undertaken. This pilot study found that despite the reservations around time constraints held by both junior and senior clinicians alike, feedback following the intervention was largely positive. The junior doctors enjoyed having a defined role and responsibility during the ward round and felt they benefited from their senior colleagues' feedback. Both seniors and junior colleagues agreed that discussing learning objectives prior to commencing the round was beneficial and made the round more learner-orientated; this enabled maximal learner-focused outcomes to be addressed and met. The juniors were generally encouraged to participate more during the round and the consultants endeavored to narrate their decision-making, both were measures that led to greater satisfaction of both parties. This was in keeping with the concept of "Legitimate peripheral participation" as described by Lave and Wenger. Overall, trainee-centered ward rounds did appear to be effective in overcoming some of the traditional barriers to teaching in the ward environment, although further work to formalize and quantify these findings, as well as using greater sample sizes from different hospital departments and the inclusion of a control group, is needed.
RESUMO
The transition period from foundation program doctor to specialty trainee can be difficult for junior doctors. This difficult period often acts as a major obstacle for learning in the workplace. Existing induction programs are commonly seen as inadequate at easing this transition, and therefore, a pilot study intervention was undertaken to assess if the initiation of "learner-centered induction programs" could help improve the confidence, knowledge acquisition, and satisfaction of junior doctors as they begin specialty training in neurosurgery. Ethnographic and anecdotal evidences were collated from junior doctors, specialty trainees, and consultants in order to investigate if further work on this subject would be beneficial. All participants were working in the Department of Neurosurgery at University Hospital Coventry and Warwickshire, Coventry, UK, over a 4-week period in March/April 2015. A review of the relevant literature was also undertaken. This report found that despite the reservations around the increased organizational demands of induction programs of this nature, as well as concerns around a single junior doctor covering the ward alone during the induction period, feedback following the intervention was largely positive. Junior doctors appreciated being taught about their roles and responsibilities from their predecessors as well as deciding among themselves what topics they wanted covering. As a result, the induction sessions tended to focus on clinical skills rather than theoretical knowledge, which most of the junior doctors believed they could cover adequately in their own time. The junior doctors felt that they benefited from learning/refreshing their relevant practical skills in a safe environment under senior supervision, prior to starting on the wards. Finally, as the induction program was of a greater duration than the traditional half day, they felt they had sufficient time to ask questions and address concerns while "on the job". Overall, "learner-centered induction programs" did appear to show promise in this pilot study with regards to increasing the confidence of junior doctors starting a neurosurgical placement and helped ease the transition process from foundation doctor to specialty trainee in neurosurgery. We believe further work to formalize and quantify these findings using questionnaires and a larger sample group as well as across successive is indicated and may help junior doctor learning and transition processes in future practice.
RESUMO
INTRODUCTION: The authors present an unusual case of small bowel obstruction in a 62-year-old man. PRESENTATION OF CASE: A 62-year-old man with a background of transitional cell carcinoma (TCC) of the bladder presented to the emergency department with abdominal pain, distension, vomiting and had not opened his bowels for three days. 3 weeks previously he had a repeat Transurtheral resection of bladder tumour (TURBT), during which there was an iatrogenic perforation of the bladder. A CT scan of the abdomen and pelvis revealed small bowel obstruction but did not identify a cause. At laparotomy the cause of the obstruction was identified as a section of the small bowel that had partially herniated into the bladder, via the perforation. The defect was repaired and the patient made an uneventful recovery. DISCUSSION: Herniation of the bowel into a defect in the bladder wall is a rare event with only 6 previous cases reported in the literature. It can cause signs and symptoms of bowel obstruction. CONCLUSION: In patients with known bladder perforations who present with symptoms and signs of bowel obstruction, bowel herniation into the bladder should be considered. Early surgical intervention may be necessary if the patient is clinically unwell with appropriate symptoms and signs and imaging does not provide conclusive answer.
RESUMO
Objective. The demand for laparoscopic surgery has led to the core laparoscopic skills course (CLSC) becoming mandatory for trainees in UK. Virtual reality simulation (VR) has a great potential as a training and assessment tool of laparoscopic skills. The aim of this study was to determine the role of the CLSC in developing laparoscopic skills using the VR. Design. Prospective study. Doctors were given teaching to explain how to perform PEG transfer and clipping skills using the VR. They carried out these skills before and after the course. During the course they were trained using the Box Trainer (BT). Certain parameters assessed. Setting. Between 2008 and 2010, doctors attending the CLSC at St Georges Hospital. Participants. All doctors with minimal laparoscopic experience attending the CLSC. Results. Forty eight doctors were included. The time taken for the PEG skill improved by 52%, total left hand and right hand length by 41% and 48%. The total time in the clipping skill improved by 57%. Improvement in clips applied in the marked area was 38% and 45% in maximum vessel stretch. Conclusions. This study demonstrated that CLSC improved some aspects of the laparoscopic surgical skills. It addresses Practice-based Learning and patient care.
