Respiratory Outcomes in Preterm Infants

The archetypal lung disease in preterm infants and one of the more common complications of preterm birth is bronchopulmonary dysplasia (BPD), which may include both parenchymal and small airway components. Common clinical manifestations of BPD include hypoxia, hypercarbia, tachypnea, and asthma-like symptoms . “Classic” or “old” BPD was frst described in 1967 by Northway et al. , and was characterized by inflammation with airway injury and alveolar fbrosis. Over time, BPD has evolved (“new” BPD), particularly with use of newer ventilation strategies and exogenous surfactant, to a phenotype characterized by fewer and larger simplifed alveoli with dysnaptic growth of the pulmonary vascular bed . Although several defnitions of BPD or chronic lung disease of prematurity have been used since 1967 , currently the most widely agreed upon defnition of BPD was developed at a NICHD workshop published in 2001 . At this workshop, the diagnosis and severity of BPD in premature infants were based on gestational age (<32 weeks or ≥32 weeks) and need for oxygen and/or respiratory support at specifed time points. This defnition was subsequently validated in 2005 . It should be recognized that this oxygen-based defnition could overestimate or underestimate the incidence of BPD as goal oxygen saturations remain controversial and can vary among clinical centers . Additionally, this oxygen-based defnition may overestimate the incidence of BPD in clinical sites at higher altitudes where the partial pressure of oxygen is decreased .

Recurrent Respiratory Papillomatosis

Papillomaviruses are a family of non-enveloped double-stranded DNA viruses that infect a number of different species including birds, cows, and humans. The human papillomavirus (HPV) can be found globally, with very little impact of geographic location on prevalence infection (De Villiers et al. 2004; Forman et al. 2012). HPV causes abnormal cellular proliferation within infected tissues, which can be broadly categorized as mucosal or cutaneous; HPV types that infect mucosal tissues are the cause of many benign neoplastic conditions such as condylomata acuminata (genital warts) and recurrent respiratory papillomatosis, and those types that infect cutaneous tissues are the cause of common skin warts (verrucae). HPV gained attention following the discovery that it is the causative agent in cervical cancer (zur Hausen 1976, 1996). Since, it has also been shown to be involved in the genesis of some head and neck cancers, as well as penile, vaginal, vulva, and anogenital cancers (Forman et al. 2012). Over 170 different HPV types have been sequenced to date (de Villiers 2013), a number that has been rising steadily with the improvement of sequencing methods. It can be diffcult to ascertain the precise portion of the population that is infected at any given time, as in most cases the virus remains latent or shows no symptoms. Up to 80% of sexually active women harbor a genital HPV infection at any one time, and men are thought to be similarly afflicted (Antonsson et al. 2000; Donne et al. 2010; Doorbar et al. 2015).

Depression and Anxiety in Patients with Chronic Respiratory Diseases

Mood disorders are often eclipsed by the primary task of respiratory management in those with chronic respiratory diseases. This is likely for a variety of reasons, including that it is not the forte of the primary respiratory provider to identify and/or manage these symptoms, that the presenting problem is the respiratory illness itself and that resources to identify and manage quality of life issues and mood disorders are often lacking. Though pharmacological options are generally readily available, identification of the mood disturbance is, in itself, time-consuming and requires some expertise to properly identify. Additionally, resources of psychotherapists with expertise in behavioral medicine are lacking. The largest of psychosocial problems faced by those with respiratory illnesses might be the same issues as those faced by any patient facing significant medical challenges. Though there may be some common psychosocial difficulties between the patients who share specific medical disorders, to some degree, individual differences with regard to resilience, coping strategies, comorbid complications, disease manifestation, hardiness, meaning attributed to the disease, and psychosocial supports all influence the direction and toll the disease itself may take on the individual. Lazarus describes a pattern of appraisal which is critical to any stressors; this involves the person evaluating the threat of the stress as well as the resources they need to minimize, tolerate, or eradicate the stressor. This appraisal process is critical to the patient’s future steps of how to rally resources to address the needs for managing the illness. It is at this stage that the patient is in vital need of resources to facilitate decision making and that they are vulnerable to decompensation in decision processing if they cannot rally these resources.
