Lower prevalence of congenital cytomegalovirus infection in Portugal: possible ...

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...

Kingella kingae: An Unlikely Cause of Meningitis

Kingella kingae is the leading cause of osteoarticular infections between 6 and 48 months, a well-known cause of pediatric bacteremia and endocarditis and has been rarely associated with meningitis. We report a case of a healthy 10-year-old boy with meningitis due to Kingella kingae who presented with a history of severe headache, vomiting and prostration.

Acute Kidney Injury Associated with COVID-19 Infection: a Case Report

SARS-Cov2 infection is a highly transmissible disease associated with serious pulmonary disease. Renal involvement is frequent and associated with poor prognosis; however, mechanisms of kidney injury are not well established. We present a SARS-Cov2 patient with severe acute kidney injury. Kidney biopsy findings revealed a pattern of acute tubular necrosis with isometric vacuolization of the proximal tubule. The...

High-Grade Urothelial Carcinoma in a Kidney Transplant Recipient After JC Virus...

Kidney transplant (KT) recipients have an increased risk for urothelial carcinoma. A role for JC virus (JCV) in human cancers is not yet proved but there is an increasingly reported association between BK virus (BKV) nephropathy and renourinary neoplasms. We report a KT recipient who developed a high-grade urothelial carcinoma 5 years after a diagnosis of JCV nephropathy and 9 years after kidney transplantation...

Recurrent Maternal CMV Infection Associated with Symptomatic Congenital Infecti...

Human cytomegalovirus (CMV) is the most widespread agent of congenital infection in humans and is still a challenging issue. Despite lower rates of vertical transmission being associated with recurrent infection when compared with primary infection, the first still represents the majority of congenital infections worldwide. Based on data from active reporting, we explored the influence of maternal primary/non-p...

Lawsonella clevelandensis as the causative agent of a breast abscess

Lawsonella clevelandensis is a Gram-stain-positive, partially acid-fast, anaerobic, being considered a new species within a new genus in the suborder Corynebacterineae. There are only a few cases reported worldwide. This is a fastidious microorganism, difficult to identify by conventional methods, leading to inappropriate treatments. The authors report a case of a 29-year-old woman with a 3-week evolution of a ...

Rubella in Sub-Saharan Africa and sensorineural hearing loss: a case control study

Rubella infection can affect several organs and cause birth defects that are responsible for congenital rubella syndrome (CRS). Congenital hearing loss is the most common symptom of this syndrome, occurring in approximately 60% of CRS cases. Worldwide, over 100 000 babies are born with CRS every year. There is no specific treatment for rubella, but the disease is preventable by vaccination. Since 1969, the rube...
