  • Respiratory Syncytial Virus Bronchiolitis in Children DUSTIN K
    Respiratory Syncytial Virus Bronchiolitis in Children DUSTIN K. SMITH, DO; SAJEEWANE SEALES, MD, MPH; and CAROL BUDZIK, MD Naval Hospital Jacksonville, Jacksonville, Florida Bronchiolitis is a common lower respiratory tract infection in infants and young children, and respiratory syncytial virus (RSV) is the most common cause of this infection. RSV is transmitted through contact with respiratory droplets either directly from an infected person or self-inoculation by contaminated secretions on surfaces. Patients with RSV bronchiolitis usually present with two to four days of upper respiratory tract symptoms such as fever, rhinorrhea, and congestion, followed by lower respiratory tract symptoms such as increasing cough, wheezing, and increased respira- tory effort. In 2014, the American Academy of Pediatrics updated its clinical practice guideline for diagnosis and man- agement of RSV bronchiolitis to minimize unnecessary diagnostic testing and interventions. Bronchiolitis remains a clinical diagnosis, and diagnostic testing is not routinely recommended. Treatment of RSV infection is mainly sup- portive, and modalities such as bronchodilators, epinephrine, corticosteroids, hypertonic saline, and antibiotics are generally not useful. Evidence supports using supplemental oxygen to maintain adequate oxygen saturation; however, continuous pulse oximetry is no longer required. The other mainstay of therapy is intravenous or nasogastric admin- istration of fluids for infants who cannot maintain their hydration status with oral fluid intake. Educating parents on reducing the risk of infection is one of the most important things a physician can do to help prevent RSV infection, especially early in life. Children at risk of severe lower respiratory tract infection should receive immunoprophy- laxis with palivizumab, a humanized monoclonal antibody, in up to five monthly doses.

  • Allergic Fungal Airway Disease Rick EM, Woolnough K, Pashley CH, Wardlaw AJ
    REVIEWS Allergic Fungal Airway Disease Rick EM, Woolnough K, Pashley CH, Wardlaw AJ Institute for Lung Health, Department of Infection, Immunity & Inflammation, University of Leicester and Department of Respiratory Medicine, University Hospitals of Leicester NHS Trust, Leicester, UK J Investig Allergol Clin Immunol 2016; Vol. 26(6): 344-354 doi: 10.18176/jiaci.0122 Abstract Fungi are ubiquitous and form their own kingdom. Up to 80 genera of fungi have been linked to type I allergic disease, and yet, commercial reagents to test for sensitization are available for relatively few species. In terms of asthma, it is important to distinguish between species unable to grow at body temperature and those that can (thermotolerant) and thereby have the potential to colonize the respiratory tract. The former, which include the commonly studied Alternaria and Cladosporium genera, can act as aeroallergens whose clinical effects are predictably related to exposure levels. In contrast, thermotolerant species, which include fungi from the Candida, Aspergillus, and Penicillium genera, can cause a persistent allergenic stimulus independent of their airborne concentrations. Moreover, their ability to germinate in the airways provides a more diverse allergenic stimulus, and may result in noninvasive infection, which enhances inflammation. The close association between IgE sensitization to thermotolerant filamentous fungi and fixed airflow obstruction, bronchiectasis, and lung fibrosis suggests a much more tissue-damaging process than that seen with aeroallergens. This review provides an overview of fungal allergens and the patterns of clinical disease associated with exposure. It clarifies the various terminologies associated with fungal allergy in asthma and makes the case for a new term (allergic fungal airway disease) to include all people with asthma at risk of developing lung damage as a result of their fungal allergy.

Perez, MD*‡ *Cleveland Clinic Pediatric Institute, Cleveland, OH. †Cleveland Clinic Children’s Hospital for Rehabilitation, The Cleveland Clinic, Cleveland, OH. ‡Department of Community Pediatrics, Independence Family Health Center, Independence, OH. Practice Gaps 1. Respiratory syncytial virus (RSV) is the most common respiratory pathogen in infants and young children worldwide. Although the most effective management of this infection remains supportive care, many patients continue to be managed with therapies that lack the support of scientific evidence. 2. Although the quest for a safe and effective vaccine remains unsuccessful, the more vulnerable patients can be protected with passive prophylaxis. Because of limited clinical benefits and high costs, RSV prophylaxis should be limited to high-risk infants as directed by the most current evidence-based guidelines that, however, are not consistently followed. 3. The acute phase of this infection is often followed by episodes of wheezing that recur for months or years and usually lead to a physician diagnosis of asthma. The phenotype of post-RSV wheezing is different from atopic asthma, yet it is usually managed using the same pharmacologic therapy with often ineffective results.

  • An Uncommon Etiological Factor for Aspiration Pneumonitis Caused By
    Cao et al. BMC Pulm Med (2021) 21:254 https://doi.org/10.1186/s12890-021-01620-5 CASE REPORT Open Access An uncommon etiological factor for aspiration pneumonitis caused by spontaneous sphenoid sinus meningoencephalocele with cerebrospinal fuid rhinorrhea: a case report Jiayu Cao1†, Wei Liu2†, Li Wang1, Yujuan Yang1, Yu Zhang1* and Xicheng Song1 Abstract Background: Aspiration pneumonitis is an infammatory disease of the lungs which is difcult to diagnose accu- rately. Large-volume aspiration of oropharyngeal or gastric contents is essential for the development of aspiration pneumonitis. The role of cerebrospinal fuid (CSF) rhinorrhea is often underestimated as a rare etiological factor for aspiration in the diagnosis process of aspiration pneumonitis. Case presentation: We present a case of a patient with 4 weeks of right-sided watery rhinorrhea accompanied by intermittent postnasal drip and dry cough as the main symptoms. Combined with clinical symptoms, imaging exami- nation of the sinuses, and laboratory examination of nasal secretions, she was initially diagnosed as spontaneous sphenoid sinus meningoencephalocele with CSF rhinorrhea, and intraoperative endoscopic fndings and postopera- tive pathology also confrmed this diagnosis. Her chest computed tomography showed multiple focculent ground glass density shadows in both lungs on admission. The patient underwent endoscopic resection of meningoenceph- alocele and repair of skull base defect after she was ruled out of viral pneumonitis. Symptoms of rhinorrhea and dry cough disappeared, and pneumonitis was improved 1 week after surgery and cured 2 months after surgery. Persistent CSF rhinorrhea caused by spontaneous sphenoid sinus meningoencephalocele was eventually found to be a major etiology for aspiration pneumonitis although the absence of typical symptoms and well-defned risk factors for aspira- tion, such as dysphagia, impaired cough refex and refux diseases.

  • Current Concepts in Adult Acute Rhinosinusitis ANN M
    Current Concepts in Adult Acute Rhinosinusitis ANN M. ARING, MD, and MIRIAM M. CHAN, PharmD, OhioHealth Riverside Methodist Hospital, Columbus, Ohio Acute rhinosinusitis is one of the most common conditions that physicians treat in ambulatory care. Most cases of acute rhinosinusitis are caused by viral upper respiratory infections. A meta-analysis based on individual patient data found that common clinical signs and symptoms were not effective for identifying patients with rhinosinusitis who would benefit from antibiotics.C-reactive protein and erythrocyte sedimentation rate are somewhat useful tests for confirming acute bacterial maxillary sinusitis. Four signs and symptoms that significantly increase the likelihood of a bacterial cause when present are double sickening, purulent rhinorrhea, erythrocyte sedimentation rate greater than 10 mm per hour, and purulent secretion in the nasal cavity. Although cutoffs vary depending on the guideline, anti- biotic therapy should be considered when rhinosinusitis symptoms fail to improve within seven to 10 days or if they worsen at any time. First-line antibiotics include amoxicillin with or without clavulanate. Current guidelines support watchful waiting within the first seven to 10 days after upper respiratory symptoms first appear. Evidence on the use of analgesics, intranasal corticosteroids, and saline nasal irrigation for the treatment of acute rhinosinusitis is poor. Nonetheless, these therapies may be used to treat symptoms within the first 10 days of upper respiratory infection. Radiography is not recommended in the evaluation of uncomplicated acute rhinosinusitis. For patients who do not respond to treatment, computed tomography of the sinuses without contrast media is helpful to evaluate for possible complications or anatomic abnormalities.
