Coronavirus disease 2019 is an infectious disease that can present with a wide range of symptoms. Abdominal pain is less common than other symptoms but is more frequent among patients with severe disease. Various abdominal imaging findings are described in the literature for children and adults with COVID-19 infection. Mesenteric lymphadenopathy is reported in pediatric patients with COVID-19 gastrointestinal infection. It is very rarely reported in the adult population.We report a case of an adult male with multiple risk factors, who presented with severe abdominal pain and tenderness in the right inguinal fossa. He was evaluated for differential diagnosis of acute appendicitis, renal colic, diabetic ketoacidosis (DKA), and COVID-19. His investigations showed normal laboratory tests and a normal chest radiograph. His CT abdomen showed a normal appendix and multiple prominent mesenteric lymph nodes. His COVID-19 PCR was positive. He was discharged after pain relief with home isolation instructions and symptomatic management.Our case represents an atypical clinical presentation of COVID-19 infection in many ways. His laboratory investigations were not suggestive of COVID-19. Our patient's abdominal imaging findings represent a rare association of COVID-19 with mesenteric lymphadenitis in adults. The clinical course of our patient was smooth after discharge and he did not develop any complications of COVID-19 despite multiple risk factors. Our case reminds the significance of keeping broad diagnostic differentials in the emergency department. Although mesenteric lymphadenitis is often a self-limiting condition affecting children and young adults, it is the most frequent alternative diagnosis of acute appendicitis and intussusception. Mesenteric lymphadenitis can be the sole atypical presentation of COVID-19 in adults. Atypical presentations are not uncommon due to the scarcity of data on this evolving disease.
Methicillin-susceptible Staphylococcus aureus (MSSA) is quite common in the environment. It can lead to a wide range of infections varying from simple boils to disseminated and metastatic infections. Disseminated multifocal MSSA infection without infective endocarditis is extremely rare. We report a case of a 48-year-old diabetic male who presented with complaints of back pain, lower limb weakness, urinary retention, and saddle sensation loss. His imaging showed an epidural abscess, spondylitis, multiple paraspinous abscess collections, iliopsoas and gluteal abscess formation, multiple abdominal abscesses, multiple cavitating lung nodules, left-sided empyema, and azygos venous thrombosis. He was managed with urgent laminectomy and evacuation of spinal epidural abscess. He was admitted under the medical team for further multidisciplinary patient care. Emergency physicians and internists should be able to recognize such cases early on to make appropriate management plans. Misdiagnosis and delay in treatment initiation can lead to high mortality and poor patient outcomes. Advanced imaging techniques should be utilized to avoid missed foci. Improved source control results in better patient outcomes.
Herd behavior is a commonly used term to describe the conduct of different individuals in a group acting without using an individual thought process. The term was first coined by British surgeon Wilfred Trotter in 1914. This editorial will elaborate on how herd behavior has affected the healthcare industry and will include examples from the coronavirus disease 2019 (COVID-19) pandemic. Many interventions were introduced during the initial period of the pandemic, some of them later proved to be either incorrect or only beneficial to a selected group of patients. The nonmedical intervention included personal protective equipment (PPE), the establishment of fever clinics, and telemedicine. Some of these interventions were beneficial and will likely continue after the pandemic. The aim of this editorial is to highlight observed herd behavior in medical practice during pandemics and endorses the need for evaluation of evidence rigorously.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
