Miliary tuberculosis: a severe opportunistic infection in juvenile systemic lupus erythematosus patients.

Introduction: One of the main issues in juvenile systemic lupus erythematosus (JSLE) patients is infection, such as tuberculosis (TB). Of note, SLE patients are susceptible to pulmonary and extrapulmonary TB. However, to our knowledge, this contagious disease was rarely reported in pediatric lupus population, particularly diffuse or miliary TB.

Cytomegalovirus infection in transplant recipients.

Cytomegalovirus infection is a frequent complication after transplantation. This infection occurs due to transmission from the transplanted organ, due to reactivation of latent infection, or after a primary infection in seronegative patients and can be defined as follows: latent infection, active infection, viral syndrome or invasive disease. This condition occurs mainly between 30 and 90 days after transplantation.

Objective:: To assess the prevalence of physical inactivity among adolescents with HIV/AIDS, as well as associated factors.

Methods:: Ninety-one adolescents (from 10 to 19 years old) with HIV/AIDS who are patients at a university follow-up service were interviewed. Anthropometric data (weight, height, and waist circumference) were measured twice; clinical information was obtained from medical records, and habitual physical activity was assessed by a questionnaire proposed by Florindo et al.

An outbreak of invasive fusariosis in a children's cancer hospital.

Fusarium is considered an emerging pathogen, and there are few reports of fusariosis in children. The objective of this study was to describe an outbreak of invasive fusariosis in a children's cancer hospital. A neutropenic 17-year-old male patient hospitalized for 10 days for a relapse of acute myeloid leukaemia, under chemotherapy, presented fever without any other symptoms; a thoracic computerized tomography showed bilateral pulmonary nodules.

Management of post-transplant Epstein-Barr virus-related lymphoproliferative disease in solid organ and hematopoietic stem cell recipients.

Epstein-Barr virus (EBV)-related post-transplant lymphoproliferative disease (PTLD) is one of the most serious complications associated with solid organ and hematopoietic stem cell transplantation. PTLD is most frequently seen with primary EBV infection post-transplant, a common scenario for pediatric solid organ recipients. Risk factors for infection or reactivation of EBV following solid organ transplant are stronger immunosuppressive therapy regimens, and being seronegative for receptor.
