BACKGROUND: Congenital Zika virus (ZIKV) infection can be detected in both the presence and absence of microcephaly, and manifests as a number of signs and symptoms detected clinically and by neuroimaging. However, to date, qualitative and quantitative measures for the purpose of diagnosis and prognosis are limited. OBJECTIVES: Main objectives of this study conducted on fetuses and infants with confirmed congenital ZIKV infection and detected brain abnormalities are: 1) To assess the prevalence of microcephaly and the frequency of the anomalies including a detailed description based on ultrasound and magnetic resonance imaging (MRI) in fetuses and ultrasound, MRI and computed tomography imaging postnatally; 2) To provide quantitative measures of fetal and infant brain findings by MRI using volumetric analyses and diffusion weighted imaging (DWI); 3) To obtain additional information from placental and fetal histopathological assessments and postnatal clinical evaluations...

BACKGROUND: Immediate initiation of antiretroviral therapy (ART) in asymptomatic adults with CD4 counts higher than 500 cells per μL, as recommended, might not always be possible in resource-limited settings. We aimed to identify subgroups of individuals who would benefit most from immediate treatment. METHODS: The START trial was a randomised controlled trial in asymptomatic, HIV-positive adults previously untreated with ART. Participants with CD4 counts higher than 500 cells per μL were randomly assigned to receive immediate ART or to defer ART until CD4 counts were lower than 350 cells per μL...

Cutaneous granulomatosis is a heterogeneous group of diseases, characterized by a skin inflammatory reaction triggered by a wide variety of stimuli, including infections, foreign bodies, malignancy, metabolites, and chemicals. From a pathogenic point of view, they are divided into non-infectious and infectious granulomas. Pathophysiological mechanisms are still poorly understood. Non-infectious granulomatous skin diseases include granuloma annulare, necrobiosis lipoidica, rheumatic nodules, foreign body granulomas, cutaneous sarcoidosis, and interstitial granulomatous dermatitis...

BACKGROUND AND AIM OF THE WORK: Bone marrow (BM) abnormalities in the spine are a common, sometimes unexpected, finding on Magnetic Resonance Imaging (MRI), which is the most sensitive imaging modality to evaluate the marrow, and their interpretation can be difficult for the unexperienced radiologist. In this review, the MRI appearance of normal age-related BM changes, as well as the imaging features of benign and malignant diseases, are presented. DISCUSSION: A large variety of BM signal alterations has been identified and described, including normal variants, BM reconversion,  degenerative changes, infections, spondyloarthritis and osteonecrosis, trauma, neoplastic lesions (both primary or metastatic), post-radiation and chemotherapy sequelae...

Equine serum hepatitis (i.e., Theiler's disease) is a serious and often life-threatening disease of unknown etiology that affects horses. A horse in Nebraska, USA, with serum hepatitis died 65 days after treatment with equine-origin tetanus antitoxin. We identified an unknown parvovirus in serum and liver of the dead horse and in the administered antitoxin. The equine parvovirus-hepatitis (EqPV-H) shares <50% protein identity with its phylogenetic relatives of the genus Copiparvovirus. Next, we experimentally infected 2 horses using a tetanus antitoxin contaminated with EqPV-H...

Wiskott-Aldrich syndrome is a rare X-linked recessive disease resulting from variations in the WAS gene. Wiskott-Aldrich syndrome is sometimes difficult to differentiate from immune thrombocytopenic purpura. A 2-month-old boy was admitted to our hospital for purpura and thrombocytopenia. His mean platelet volume was reported to be normal. Treatment with intravenous immunoglobulins failed to improve the patient's platelet count. Subsequently, an acute cytomegalovirus infection was confirmed by serological testing and antigenemia...

Household contacts of pulmonary tuberculosis (TB) patients are at increased risk of TB infection and disease. However, their risk in relation to the intensity of exposure remains unknown.We studied smear-positive TB cases and their household contacts in Vitória, Brazil. We collected clinical, demographic and radiographic information from TB cases, and obtained tuberculin skin test (TST) and QuantiFERON-TB Gold (QFT) results from household contacts. We measured intensity of exposure using a proximity score and sleep location in relation to the TB index case and defined infection by TST ≥10 mm or QFT ≥0...

BACKGROUND: Pneumocephalus, illustrated by air in the cranial vault is relatively infrequent and generally associated with neurosurgery, trauma, meningitis and barotrauma. However cases of spontaneous non-traumatic pneumocephalus remain rare. While the relationship between continuous positive airway pressure (CPAP) and atraumatic pneumocephalus has been previously reported, to our knowledge the rare presentation associated with sinus wall osteomyelitis has never been described. We summarize here the case of a 67-year-old woman's acute presentation of Streptococcus salvarius infection after a sudden drop in her consciousness...

Essential HIV cure-related clinical trials (HCRCT) have a potentially high-risk profile in terms of participants' health, which could hinder enrollment by people living with HIV (PLWH) and healthcare professionals (HP). The ANRS-APSEC survey is part of the IAS "Towards an HIV cure" initiative, which promotes multidisciplinary research for a safe, affordable and scalable cure. The study objectives were to understand the psychosocial mechanisms underlying PLWH and HP viewpoints about future HCRCT. Six focus group discussions (three with PLWH (n = 21) and three with HP (n = 30)) were held in three French infectious disease units...

During the Zika epidemic in Brazil, a baby was born at term with microcephaly and arthrogryposis. The mother had Zika symptoms at 10 weeks of gestation. At 17 weeks, ultrasound showed cerebral malformation and ventriculomegaly. At 24 weeks, the amniotic fluid contained ZIKV RNA and at birth, placenta and maternal blood were also positive using RT-qPCR. At birth the baby urine contained ZIKV RNA, whereas CSF at birth and urine at 17 days did not. Seizures started at 6 days. EEG was abnormal and CT scan showed cerebral atrophy, calcifications, lissencephaly, ventriculomegaly, and cerebellar hypoplasia...

Background: Bordetella pertussis is a human pathogen responsible for serious respiratory illness. The disease is most severe in infants too young to be vaccinated with most hospitalizations and deaths occurring within this age group. The Advisory Committee on Immunization Practices recommended immunization of pregnant women to protect infants from birth until their first vaccination at six to eight weeks of age. We previously demonstrated that maternal vaccination with licensed acellular pertussis vaccines protected newborn baboons from disease...
