  • Lower prevalence of congenital cytomegalovirus infection in Portugal: possible impact of COVID-19 lockdown?
    Publication . Fernandez, C; Chasqueira, MJ; Marques, A; Rodrigues, L; Marçal, M; Tuna, M; Braz, MC; Neto, AS; Mendes, C; Lito, D; Rocha, P; Vasconcellos, G; Menezes, MF; Sousa, MJ; Nunes, C; Paixão, P
    Cytomegalovirus (CMV) is the most frequent cause of congenital infection all over the world. Its prevalence ranges from 0.2 to 2.2%. Transmission from children to their pregnant mothers is a well-known risk factor, particularly if they attend a childcare centre. This study aims to compare the prevalence of CMV congenital infection (CMV_CI) in Portugal (Lisbon) between two studies, performed respectively in 2019 and 2020. In the 2019 study, performed in two hospitals, we found a 0.67% CMV_CI prevalence, using a pool strategy previously tested with saliva samples. In the 2020 study, using the same pool approach in four hospitals (the previous and two additional), and based on 1277 samples, the prevalence was 0.078%.Conclusion: The close temporal coincidence with COVID-19 lockdown suggests that these measures may have had a significant impact on this reduction, although other explanations cannot be ruled-out. What is Known: • Cytomegalovirus is the leading cause of congenital infection. • Behavioural measures decrease cytomegalovirus seroconversion in pregnant women. What is New: • From 2019 to 2020 there was a significant reduction in the prevalence of congenital CMV infection.

  • Management of Pipkin Fractures Using a Safe Surgical Hip Dislocation
    Publication . Henriques, R; Ramalho, D; Soares do Brito, J; Rocha, P; Spranger, A; Almeida, P
    INTRODUCTION: Pipkin fractures are rare events and usually occur as a consequence for high-energy trauma. Surgery to obtain anatomical reduction and fixation is the mainstay treatment for the majority of these injuries; nonetheless, controversy exists regarding the best surgical approach. DESCRIPTION OF THE CASE: We present the case of a 41-year-old male, which sustained a type II Pipkin fracture following a motorcycle accident. In the emergency department, an emergent closed reduction was performed, followed by surgery five days later. Using a surgical hip dislocation, a successful anatomical reduction and fixation was performed. After three years of follow-up, the patient presented with a normal range of motion, absent signs for avascular necrosis or posttraumatic arthritis, but with a grade II heterotopic ossification. DISCUSSION: Safe surgical hip dislocation allows full access to the femoral head and acetabulum, without increasing the risk for a femoral head avascular necrosis or posttraumatic arthritis. Simultaneously, this surgical approach gives the opportunity to repair associated acetabular or labral lesions, which explains the growing popularity with this technique. CONCLUSION: Although technically demanding, safe surgical hip dislocation represents an excellent option in the reduction and fixation for Pipkin fractures.
