Introduction: Little is known about the clerkship (clinical) medical students’ knowledge of hand hygiene as the single most important precautionary measure to reduce nosocomial healthcare-associated infections. The aim of this study is to explore the knowledge of, and attitudes towards, hand hygiene practices among fourth-year clerkship medical students at Alfaisal University, College of Medicine, Riyadh, Saudi Arabia.Materials and Methods: A cross-sectional, paper-based, Yes/No formatted questionnaire was administered to explore the students’ knowledge of, and attitudes towards, hand hygiene practices. Data were decoded in Microsoft Excel sheet and presented as numbers and percentages.Results: One hundred and eleven students (n=111/147) participated in the questionnaire (response rate: 76%). Although the majority of students had a fair knowledge of hand hygiene practices, a number of them had some misconceptions. Only 14% of students correctly agreed to the statement: "Traditional hand washing (water, plus regular soap) decreases the number of germs." Furthermore, only 32% of students correctly answered that "hand washing with a regular soap, instead of an antiseptic soap, is better in limiting the transmission of clostridium difficile infections". Almost all students (93%) agreed to the importance of hand hygiene education in medical curricula and its awareness in healthcare centers. Despite the importance of hand hygiene, only 13% of students reviewed the respective WHO and CDC guidelines before starting their clinical training in the teaching hospital.Discussion: The students’ inadequate knowledge about hand hygiene needs to be enriched by well-structured curricular and extra-curricular programs as well as more positive attitudes by healthcare workers.

Introduction The physician-patient relationship is at the heart of the art of medicine. Patient-centered care is rapidly evolving as the standard of care as well as the optimal vehicle to achieve high-quality healthcare and good clinical outcomes. This study aims to examine the attitudes of pre-clinical (third-year) students from Alfaisal University (Riyadh, Saudi Arabia) toward the physicianpatient relationship. Methods This cross-sectional study took place during the spring 2017 academic year. All third-year students (n=210) were requested to voluntarily complete an online and anonymous questionnaire. The questionnaire covered students' demographical characteristics (gender, nationality, and cumulative grade point average) and their response to a previously validated instrument, the Patient-Practitioner Orientation Scale (PPOS), which explores the attitudes of medical students toward the doctor-patient relationship. Results In total, 132 students participated in the survey (n=132/210) with an overall response rate of 62.9%. Most respondents were female (56.8%), non-Saudi citizens (53.0%), and high achievers (70.5%). Most of the mean scores on the PPOS statements indicated patient-centered attitudes-that is, mean scores were higher than "3". The mean score for the overall PPOS was 4.0 ± 1.5, whereas the mean scores for the sharing and caring domains were 4.2 ± 1.5 and 3.8 ± 1.4, respectively. Univariate correlations between the students' demographics and their mean scores for the sharing domain, caring domain, and overall PPOS showed no statistically significant differences (p > 0.05). Conclusion The pre-clinical medical students showed favorable patient-centered attitudes. There were no statistically significant differences between students' demographics (gender, nationality, and academic performance) and PPOS scores (sharing domain, caring domain and overall score).

This study aimed to compile all the relevant studies of patients presenting with pericardial tamponade before or after diagnosis of lymphoma, describe the clinical presentations of patients with lymphoma and cardiac tamponade, and assess the difference in overall survival based on the timing of cardiac tamponade diagnosis. A comprehensive search strategy was conducted in the following databases: PubMed and Cochrane Library, using the following keywords: Lymphoma AND Cardiac Tamponade. The criteria for eligibility included cases with a confirmed diagnosis of lymphoma and cardiac tamponade, human studies, and publications in English language. The statistical analysis was performed using IBM Statistical Package for Social Sciences (SPSS) version 20. We included 48 research articles ( n = 52 cases) with adequate reporting of measured outcomes. The median age of the patients was 52 (9–94) years. Only 6 patients were noted to have primary cardiac lymphoma, while the majority of cases were considered to have secondary cardiac lymphoma (88.5%). According to the data on the type of lymphoma reported through cytology and immunohistochemistry, 49 patients were diagnosed with non-Hodgkin lymphoma, and of these cases the most common subtype was large B-cell lymphoma (42.9%). Overall, the average duration of illness was 14 ± 23 days. A total of 13 patients had distant heart sounds, 12 cases were noted to be hypotensive, and 13 subjects were found to have increased jugular venous pressure. Our retrospective study demonstrated that most patients presented with pericardial tamponade after lymphoma diagnosis, and those were mostly secondary cardiac lymphoma of the non-Hodgkin type with large B-cell as the most common subtype. Dyspnoea, oedema, and constitutional symptoms were the most common presenting signs. The median overall survival of patients with lymphoma and cardiac tamponade is 4 months, with no significant difference in mortality in the presentation timing before and after the diagnosis of lymphoma.

Patient: Male, 30Final Diagnosis: Benign pericardial schwannomaSymptoms: Chest painMedication: —Clinical Procedure: —Specialty: SurgeryObjective:Rare diseaseBackground:Primary pericardial tumors have a prevalence of between 6.7% and 12.8% of all tumors arising in the cardiac region. Pericardial schwannoma is a rare entity. It arises from the cardiac plexus and vagus nerve innervating the heart. Most of the reported cases, have presented with benign behavior, however, in rare situations, they can undergo transformation to malignant behavior When comparing the prevalence of cardiac tumors to that of pericardial tumors, the latter is much lower in occurrence. A review of English literature identified six pericardial schwannoma cases.Case Report:We present a case of a 30-year-old male patient who presented to our center with the chief complaint of six months of gradually progressive left chest pain. His past medical history (PMH) was positive for panic attacks (for which he was taking beta-blockers), paroxysmal tachycardia, sweating, and irritability. A computed tomography chest scan was done; a differential diagnosis of paraganglioma was suggested. However, histopathological examination confirmed the pericardial mass was a schwannoma. The patient was surgically treated by thoracotomy to resect the lesion.Conclusions:This case adds to the existing limited literature on pericardial schwannoma as the seventh reported case. Neurogenic cardiac tumors; our case marks the second case reported to occur in the subcarinal area near the left atrium.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a novel virus that causes multi-systemic manifestations identified as coronavirus disease 2019 . Respiratory tract symptoms are the most commonly seen in infected patients with COVID-19. Hypercoagulability state is the most common coagulopathy disorder associated with critically ill COVID-19 patients. Several inflammatory and coagulation factors such as D-dimers and fibrinogen correlate with the degree of pro-thrombotic state and burden of the disease. We describe a case of a 51-year-old man who presented with respiratory pneumonia and concomitant severe bilateral arterial thrombosis followed by right above knee amputation.
