RESUMEN
Objective: The aim of this study was to determine current and previous SARS-COV-2 infection, and describe risk factors associated with seropositivity, among HCWs and hospital staff between June and October of 2020. Methodology: Data from the day of enrollment for a prospective cohort study were analyzed to determine point prevalence and seroprevalence of SARS-CoV-2 infection in HCWs and hospital staff of a university hospital in Colombia. Respiratory samples were collected to perform RT-PCR tests, along with blood samples to measure SARS-CoV-2 IgM and IgG antibodies. Data on nosocomial and community risk factors for infection were also collected and analyzed. Findings: 420 HCWs and hospital staff members were included. The seroprevalence at baseline was 23.2%, of which 10.7% had only IgM antibodies, 0.7% had IgG, and 11.7% had IgM and IgG. The prevalence of acute SARS-CoV-2 infection was 1.9%. Being a nurse assistant was significantly associated with seropositivity when compared with all other job duties (PR 2.39, 95% CI 1.27-3.65, p = 0.01). Conclusions: Overall SARS-CoV-2 prevalence was 1.9% and seroprevalence was 23.15%. Nurse assistants, medical doctors or students, and laboratory workers had a higher possibility of being SARS-CoV-2 seropositive.
RESUMEN
Introduction: Retroperitoneal hematomas are rare complications of radical inguinal orchiectomy. This case report discusses their radiological differential diagnosis and management. Case presentation: A radical inguinal orchiectomy was performed on a 27-year-old patient. After discharge, he referred back pain. Computed tomography showed a retroperitoneal hematoma. A conservative approach was decided. Discussion: Traditionally, retroperitoneal hematomas have been considered possible radiologic pitfalls, which has therapeutical implications. This pitfall seems less likely in contemporary clinical practice.A conservative approach is preferred in stable patients, whereas active management should be offered to unstable patients. Conclusion: Future studies are necessary to offer evidence-based therapeutical options.
