A 3.5-y-old Whippet mixed-breed dog was presented with a history of respiratory distress, exercise intolerance, and generalized demodicosis. Hematologic alterations included marked leukocytosis and neutrophilia. Radiographic examination showed a diffuse interstitial and mild peripheral alveolar lung pattern and pneumomediastinum. Because the cytologic examination of the bronchoalveolar aspirate was not diagnostic and a persistent perforation of the upper respiratory tract could not be ruled out, the dog was submitted to thoracoscopy, and subsequently the left cranial lung lobe as well as mediastinal and sternal lymph nodes were resected...

BACKGROUND: Benralizumab is a humanised, anti-interleukin 5 receptor α monoclonal antibody that directly and rapidly depletes eosinophils, reduces asthma exacerbations, and improves lung function for patients with severe eosinophilic asthma. The objective of this trial was to assess the safety and efficacy of benralizumab for patients with mild to moderate, persistent asthma. METHODS: In this randomised, double-blind, placebo-controlled, phase 3 trial, we recruited patients aged 18-75 years, weighing at least 40 kg, and with a postbronchodilator reversibility in forced expiratory volume in 1 s (FEV1) of at least 12% at screening, from 52 clinical research centres in six countries...

Here we report the applicability of a protocol based on clinical conditions and risk factors (RFs) for managing 35 allogeneic hematopoietic stem cell transplantation (allo-HSCT) recipients who developed a total of 52 episodes of respiratory viral infections (RVIs) caused by respiratory syncytial virus (RSV; n=19), human parainfluenza virus (HPIV; n=29), or both (n=4) over a 2-year study period. Risk categories were classified as high risk (cat-1) when the immunodeficiency scoring index) was ≥ 3 and/or ≥ 3 RFs and/or ≥ 1 co-infective virus(es) were present; the remaining cases were classified as low risk (cat-0)...

Palivizumab, a humanized murine monoclonal antibody that recognizes antigenic site II on both the prefusion (pre-F) and postfusion (post-F) conformations of the RSV F glycoprotein, is the only prophylactic agent approved for RSV. However, its relatively low neutralizing potency and high cost has limited its use to a restricted population of infants at high risk of severe disease. Previously, we isolated a high potency neutralizing antibody, 5C4, that specifically recognizes antigenic site Ø at the apex of the pre-F trimer...

Information about the epidemiology, clinical manifestations and comorbidities of sarcoidosis among Caucasians is relatively scarce. This review focuses primarily on the data from a recently published Caucasianpredominant population-based cohort from Olmsted County, Minnesota. Overall, the incidence rate was 10.0 per 100,000 population, which suggested that sarcoidosis is less common in Caucasians than in Blacks, but is more common in Caucasians than in Asians. Intrathoracic involvement was seen in the vast majority of patients, but less than half have respiratory symptoms...

INTRODUCTION: The relationship between human papilloma virus (HPV) and upper respiratory tract pathology was better understood in recent years and represents now an issue of particular interest in carcinogenesis and in immunocompromised host. We describe a case in which a rare genotype HPV-related papillomatosis mimics laryngeal carcinoma in an immunocompromised host. METHODS: A 54-year-old woman with a history of HIV-HCV coinfection and anal and laryngeal cancer successfully treated some years before was hospitalized for severe dyspnea, cough and dysphagia...

Pasteurella multocida is a common constituent of upper respiratory tract microbiota but is frequently isolated of alpaca lung tissues from pulmonary infections. Despite its importance, very little is known about this bacteria at molecular level. In order to characterize P. multocida isolates, 24 isolates recovered from 46 mortal acute cases in young alpacas with suspected pneumonia were analyzed, using biochemical and molecular tests for capsule and LPS typing, virulence factors detection, and ERIC-PCR genetic diversity analysis...

Bovine herpesvirus 1 (BHV-1) infection may lead to conjunctivitis, upper respiratory tract problems, pneumonia, genital disorders and abortion. BHV-1 is able to spread quickly in a plaque-wise manner and invade by breaching the basement membrane (BM) barrier in the respiratory mucosa. BHV-1 Us3, a serine/threonine kinase, induces a dramatic cytoskeletal reorganization and BHV-1 Us9, a tail-anchored membrane protein, is required for axonal transport of viruses in neurons. In this study, we investigated the role of Us3 and Us9 during BHV-1 infection in the respiratory mucosa...

BACKGROUND: The common cold is a spontaneously remitting infection of the upper respiratory tract, characterised by a runny nose, nasal congestion, sneezing, cough, malaise, sore throat, and fever (usually < 37.8º C). The widespread morbidity caused by the common cold worldwide is related to its ubiquitousness rather than its severity. The development of vaccines for the common cold has been difficult because of antigenic variability of the common cold virus and the indistinguishable multiple other viruses and even bacteria acting as infective agents...

INTRODUCTION: Streptococcal species are known as the most common cause of bacterial upper respiratory tract infections (URTI). Once bacterial infection is diagnosed it demands empirical antibiotic prescription. On the other hand antimicrobial resistance is a global burden in today's medicine. For that reason, knowing of antimicrobial susceptibility patterns in population is an important background for successful treatment of bacterial caused URTI. The aim of this study was to analyze S...

Coccidioidomycosis (CM) is an infection caused by the coccidioides fungus. The spectrum of the disease ranges from a mild upper respiratory illness to severe disseminated infection that could affects the bones, joints, skin, central nervous system, and the gastrointestinal tract. Previous reports of a positive stool culture in the setting of disseminated CM are extremely rare. Herein, we describe a case of a 43-year-old immunocompetent patient with disseminated CM and evidence of positive coccidioides stool culture...

Rhinovirus has been neglected in the past because it was generally perceived as a respiratory virus only capable of causing mild common cold. Contemporary epidemiological studies using molecular assays have shown that rhinovirus is frequently detected in adult and pediatric patients with upper or lower respiratory tract infections. Severe pulmonary and extrapulmonary complications are increasingly recognized. Contrary to popular belief, some rhinoviruses can actually replicate well at 37 °C and infect the lower airway in humans...

Cough is one of the most common complaints for which sufferers seek medical assistance. However, currently available drugs are not very effective in treating cough, particularly that which follows an upper respiratory tract infection. Nonetheless, there has been a significant increase in our understanding of the mechanisms and pathways of the defensive cough as well as the hypersensitive/pathophysiological cough, both at airway and central nervous system (CNS) levels. Numerous molecules and signaling pathways have been identified as potential targets for antitussive drugs, including neurotrophins (NTs)...

The efficacy and safety of secukinumab, a fully human anti-interleukin-17A monoclonal antibody, has been evaluated for moderate to severe plaque psoriasis in global trials which have included a low proportion of Asian subjects. We analyzed the efficacy and safety of secukinumab in Taiwanese patients in a phase III global clinical trial (ERASURE). Fifty-one Taiwanese patients were randomized into s.c. placebo, 150 and 300 mg secukinumab treatment groups. The proportions of patients who achieved 75% or more improvement in Psoriasis Area and Severity Index (PASI-75) at week 12 were 87...

Nasal irrigation (NI) is an old practice of upper respiratory tract care that likely originated in the Ayurvedic medical tradition. It is used alone or in association with other therapies in several conditions-including chronic rhinosinusitis and allergic rhinitis-and to treat and prevent upper respiratory tract infections, especially in children. However, despite it being largely prescribed in everyday clinical practice, NI is not included or is only briefly mentioned by experts in the guidelines for treatment of upper respiratory tract diseases...

Data from EV-D68-infected patients demonstrate that pathological changes in the lower respiratory tract are principally characterized by severe respiratory illness in children and acute flaccid myelitis. However, lack of a suitable animal model for EV-D68 infection has limited the study on the pathogenesis of this critical pathogen, and the development of a vaccine. Ferrets have been widely used to evaluate respiratory virus infections. In the current study, we used EV-D68-infected ferrets as a potential animal to identify impersonal indices, involving clinical features and histopathological changes in the upper and lower respiratory tract (URT and LRT)...
