Study objective: To define the epidemiology, clinical manifestations, and long-term complications of respiratory viral infections in adult lung transplant recipients. Design: Retrospective review of the records of 122 adult lung transplant recipients over a 5-year period at one institution. Results: Ten episodes of infection with respiratory syncytial virus, parainfluenza, influenza, or adenovi...

There are complex interactions between airway allergy and viral infection. Available evidence suggests that viral respiratory infection can initiate, maintain and activate exacerbation of allergic conditions in respiratory tract. Innate and inflammatory responses to acute viral infection play important roles in its relationship to allergic reactions. On the other hand, biased immune responses t...

BACKGROUND Respiratory tract infection is one of the most common reasons for hospitalization among adults, and recent evidence suggests that many of these illnesses are associated with viruses. Although bacterial infection is known to complicate viral infections, the frequency and impact of mixed viral-bacterial infections has not been well studied. METHODS Adults hospitalized with respirator...

conclusions infection with hmpv and rsv are most frequent infections among pediatric patients with respiratory tract symptoms. coinfection with these viruses may exacerbate the clinical symptoms and increase hospitalization rates, especially in children younger than one year old. results the hmpv and rsv were detected in 44 (15.7%) and 84 (30.0%) samples, respectively. coinfection with both vir...

BACKGROUND Bioterrorism using anthrax claimed five lives in the United States in 2001 and remains a potential public health threat. In the aftermath of a large-scale anthrax attack, mass screening to identify early inhalational anthrax may improve both the management of individual cases and the efficiency of health resource utilization. PURPOSE To develop the evidence base for outpatient anth...

This is a report of a case with unilateral cavernous sinus thrombosis due to ipsilateral ethmoid sinusitis. A 10 year old female was admitted in our hospital with severe headache, purulent postnasal discharge, right eye proptosis and third cranial nerve palsy in the same eye. She had history of viral upper respiratory tract infection and then acute otitis media which did not improve with rou...

Viral infections are common causes of respiratory tract disease in the outpatient setting but much less common in the intensive care unit. However, a finite number of viral agents cause respiratory tract disease in the intensive care unit. Some viruses, such as influenza, respiratory syncytial virus (RSV), cytomegalovirus (CMV), and varicella-zoster virus (VZV), are relatively common. Others, s...

The factors that cause prolonged human influenza virus respiratory tract infection and determine its clinical impact and the development of drug-resistant viruses are unclear. During a 3-year period, symptomatic influenza virus excretion for 2 weeks was observed among 8 immunocompromised patients and found to be associated with lymphocytopenia at onset (8 of 8 patients) more often than with gra...

Cryptosporial and bacterial co-infection is reported in a budgerigar with clinical manifestations of septicemia and respiratory tract infection. Microscopically large number of round to oval 2-5μm cryptosporidial organisms were found to be lodged on the parabronchial epithelial cells of the respiratory tract. The bacterial colonies were seen around the parabronchial spaces of the lung tissue. I...

Viral infections are known to modulate the upper respiratory tract microbiome, but few studies have addressed differences in nasopharyngeal microbiome following SARS-CoV-2 infection. Using swab medical waste samples from 79 confirmed positive and 20 negative patients, we assessed composition with metagenomic sequencing. COVID-19 status breathing assistive device use was associated beta diversit...
