BACKGROUND Chloroquine-azithromycin is being evaluated as combination therapy for malaria. It may provide added benefit in treating or preventing bacterial infections that occur in children with malaria. OBJECTIVE We aim to evaluate the effect of treating clinical malaria with chloroquine-azithromycin on the incidence of respiratory-tract and gastrointestinal-tract infections compared to trea...
The aim of the study was to define the respiratory morbidity caused by lymphocytic interstitial pneumonitis (LIP) in children with vertically acquired HIV infection. A retrospective case note review was performed on 95 children attending three London hospitals. Clinical and radiological evidence of LIP, acute lower respiratory tract infections, and chronic lung disease was obtained using a stru...
It is not known whether respiratory syncytial virus spreads beyond the respiratory tract. With the use of reverse transcriptase polymerase chain reaction, we found viral and transcribed RNA in cells from the arterial blood of four children with bronchiolitis but none in serum or cerebrospinal fluid. Respiratory syncytial virus might therefore spread outside the respiratory tract.
Among 40 allogeneic stem cell transplant recipients who developed symptomatic respiratory syncytial virus infection, including 22 patients with lower respiratory tract infection, 19 received palivizumab (9 of whom had upper respiratory tract disease). Palivizumab did not prevent progression to lower respiratory infection and had no impact on the overall survival rate.
Respiratory syncytial virus (RSV) has emerged since its isolation from infected children in 1957 as an important respiratory pathogen (Falsey et al, 2005; Hall et al, 2009; Nair et al, 2010; Ruuskanen et al, 2011). Generally, infection is restricted to the upper respiratory tract and not associated with long-term pathology, but progression to a more severe lower respiratory tract infection is f...
OBJECTIVE To assess the impact of respiratory tract infection in the postoperative period of cardiac surgery in relation to mortality and to identify patients at higher risk of developing this complication. METHODS Cross-sectional observational study conducted at the Recovery of Cardiothoracic Surgery, using information from a database consisting of a total of 900 patients operated on in this...
The 2019 novel coronavirus (2019-nCoV) behind the ongoing outbreak - which the World Health Organization has declared an international public health emergency - was named after the family of viruses it belongs to. The term “coronavirus” may have initially been unfamiliar to many, but most everyone has encountered milder forms of such viruses, of which four strains cause about a fifth of common ...
Background and Purpose: The obstruction of the upper respiratotri for tract (URT) is one of the most important reasons patients recurrent referral to the ENT clinic. Adentonsilar hypertrophy is almost common reason of the upper respiratory tract obstruction, and it will cause some changes in lung volumes and also in blood gases. The purpose of this study was to determine the effects of tonsil...
Influenza virus tissue tropism defines the host cells and tissues that support viral replication and contributes to determining which regions of the respiratory tract are infected in humans. The location of influenza virus infection along the respiratory tract is a key determinant of virus pathogenicity and transmissibility, which are at the basis of influenza burdens in the human population. A...
D between causes of respiratory distress in animals that have acute signs is challenging. Clinical signs are generally nonspecific and can result from congestive heart failure as well as primary respiratory tract disease. Data gathered through medical history, physical examination, and thoracic radiography can be ambiguous or nonconfirmatory. Differentiation of the common causes of respiratory ...
